[0118] The following will be combined with the accompanying drawings to clearly and in detail describe the technical solutions in some embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments provided by the present disclosure, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present disclosure.

[0119] In optical communication technology, in order to establish information transmission between information processing devices, it is necessary to load information onto light and use the propagation of light to achieve information transmission. Here, the light loaded with information is an optical signal. When optical signals are transmitted in information transmission equipment, the loss of optical power can be reduced, so high-speed, long-distance, and low-cost information transmission can be achieved. The signals that information processing equipment can recognize and process are electrical signals. Information processing equipment usually includes optical network terminals (Optical Network Unit, ONU), gateways, routers, switches, mobile phones, computers, servers, tablets, televisions, etc., and information transmission equipment usually includes optical fibers and optical waveguides.

[0120] The optical module can realize the mutual conversion between optical signals and electrical signals between information processing equipment and information transmission equipment. For example, at least one of the optical signal input end or the optical signal output end of the optical module is connected to an optical fiber, and at least one of the electrical signal input end or the electrical signal output end of the optical module is connected to an optical network terminal; the first optical signal from the optical fiber is transmitted to the optical module, and the optical module converts the first optical signal into a first electrical signal, and transmits the first electrical signal to the optical network terminal; the second electrical signal from the optical network terminal is transmitted to the optical module, and the optical module converts the second electrical signal into a second optical signal, and transmits the second optical signal to the optical fiber. Since multiple information processing devices can transmit information through electrical signals, at least one of the multiple information processing devices needs to be directly connected to the optical module, and all information processing devices do not need to be directly connected to the optical module. Here, the information processing device directly connected to the optical module is called the upper computer of the optical module. In addition, the optical signal input end or the optical signal output end of the optical module can be called an optical port, and the electrical signal input end or the electrical signal output end of the optical module can be called an electrical port.

[0121] FIG1 is a partial structural diagram of an optical communication system provided according to some embodiments of the present disclosure. As shown in FIG1 , the optical communication system mainly includes a remote information processing device 1000 , a local information processing device 2000 , a host computer 100 , an optical module 200 , an optical fiber 101 and a network cable 103 .

[0122] One end of the optical fiber 101 extends toward the remote information processing device 1000, and the other end of the optical fiber 101 is connected to the optical module 200 through the optical port of the optical module 200. The optical signal can be totally reflected in the optical fiber 101, and the propagation of the optical signal in the total reflection direction can almost maintain the original optical power. The optical signal undergoes multiple total reflections in the optical fiber 101 to transmit the optical signal from the remote information processing device 1000 to the optical module 200, or to transmit the optical signal from the optical module 200 to the remote information processing device 1000, thereby realizing long-distance, low-power loss information transmission.

[0123] The optical communication system may include one or more optical fibers 101, and the optical fibers 101 are detachably connected or fixedly connected to the optical module 200. The host computer 100 is configured to provide data signals to the optical module 200, receive data signals from the optical module 200, or monitor or control the working state of the optical module 200.

[0124] The host computer 100 includes a substantially rectangular housing and an optical module interface 102 disposed on the housing. The optical module interface 102 is configured to connect to the optical module 200 so that the host computer 100 and the optical module 200 establish a unidirectional or bidirectional electrical signal connection.

[0125] The host computer 100 also includes an external electrical interface, which can be connected to an electrical signal network. For example, the external electrical interface includes a Universal Serial Bus (USB) interface or a network cable interface 104, and the network cable interface 104 is configured to access the network cable 103 so that the host computer 100 establishes a unidirectional or bidirectional electrical signal connection with the network cable 103. One end of the network cable 103 is connected to the local information processing device 2000, and the other end of the network cable 103 is connected to the host computer 100, so as to establish an electrical signal connection between the local information processing device 2000 and the host computer 100 through the network cable 103. For example, the third electrical signal sent by the local information processing device 2000 is transmitted to the host computer 100 through the network cable 103, and the host computer 100 generates a second electrical signal according to the third electrical signal. The second electrical signal from the host computer 100 is transmitted to the optical module 200, and the optical module 200 converts the second electrical signal into a second optical signal, and transmits the second optical signal to the optical fiber 101, and the second optical signal is transmitted to the remote information processing device 1000 in the optical fiber 101. For example, the first optical signal from the remote information processing device 1000 is transmitted through the optical fiber 101, and the first optical signal from the optical fiber 101 is transmitted to the optical module 200, and the optical module 200 converts the first optical signal into a first electrical signal, and the optical module 200 transmits the first electrical signal to the host computer 100, and the host computer 100 generates a fourth electrical signal according to the first electrical signal, and transmits the fourth electrical signal to the local information processing device 2000. It should be noted that the optical module is a tool for realizing the mutual conversion between optical signals and electrical signals. During the conversion process between the optical signals and electrical signals, the information does not change, but the encoding and decoding methods of the information can change.

[0126] The host computer 100 includes not only an optical network terminal but also an optical line terminal (OLT), an optical network device (ONT), or a data center server.

[0127] FIG2 is a partial structural diagram of a host computer according to some embodiments. In order to clearly show the connection relationship between the optical module 200 and the host computer 100, FIG2 only shows the structure of the host computer 100 related to the optical module 200. As shown in FIG2, the host computer 100 also includes a PCB circuit board 105 arranged in the housing, a cage 106 arranged on the surface of the PCB circuit board 105, a heat sink 107 arranged on the cage 106, and an electrical connector arranged inside the cage 106. The electrical connector is configured to access the electrical port of the optical module 200; the heat sink 107 has a protruding structure such as fins that increase the heat dissipation area.

[0128] The optical module 200 is inserted into the cage 106 of the host computer 100, and the cage 106 fixes the optical module 200. The heat generated by the optical module 200 is transferred to the cage 106 and then diffused through the heat sink 107. After the optical module 200 is inserted into the cage 106, the electrical port of the optical module 200 is connected to the electrical connector inside the cage 106, so that the optical module 200 establishes a bidirectional electrical signal connection with the host computer 100. In addition, the optical port of the optical module 200 is connected to the optical fiber 101, so that the optical module 200 establishes a bidirectional optical signal connection with the optical fiber 101.

[0129] FIG3 is a structural diagram of an optical module provided according to some embodiments of the present disclosure, and FIG4 is an exploded diagram of an optical module provided according to some embodiments of the present disclosure; wherein: the x-axis direction is the length direction of the optical module 200, the y-axis direction is the width direction of the optical module 200, and the z-axis direction is the height direction of the optical module 200. As shown in FIG3 and FIG4, the optical module 200 includes a shell, a circuit board 300 disposed in the shell, a light emitting component 400, and a light receiving component 500. However, the present disclosure is not limited thereto, and in some embodiments, the optical module 200 includes one of the light emitting component 400 and the light receiving component 500.

[0130] The housing comprises an upper housing 201 and a lower housing 202 . The upper housing 201 is assembled and connected to the lower housing 202 to form the housing having two openings 203 and 204 . The outer contour of the housing is generally a square body.

[0131] In some embodiments, the lower shell 202 includes a bottom plate 2021 and lower side plates located on both sides of the bottom plate 2021 and vertically arranged with respect to the bottom plate 2021; the upper shell 201 includes a cover plate 2011, and the cover plate 2011 is covered on the two lower side plates of the lower shell 202 to form the above-mentioned shell.

[0132] In some embodiments, the lower shell 202 includes a bottom plate 2021 and a first lower side plate 2022 and a second lower side plate 2023 located on both sides of the bottom plate 2021 and perpendicular to the bottom plate 2021; the upper shell 201 includes a cover plate 2011 and a first upper side plate 2012 and a second upper side plate 2013 located on both sides of the cover plate 2011 and perpendicular to the cover plate 2011, and the first lower side plate 2022 and the second lower side plate 2023 are respectively connected to the first upper side plate 2012 and the second upper side plate 2013 to realize the assembly connection between the upper shell 201 and the lower shell 202.

[0133] The direction of the connection line of the two openings 203 and 204 may be consistent with the length direction of the optical module 200, or may be inconsistent with the length direction of the optical module 200. For example, the opening 203 is located at the end of the optical module 200 (the right end of FIG. 3 ), and the opening 204 is also located at the end of the optical module 200 (the left end of FIG. 3 ). Alternatively, the opening 203 is located at the end of the optical module 200, and the opening 204 is located at the side of the optical module 200. The opening 203 is an electrical port, and the gold finger of the circuit board 300 extends from the electrical port and is inserted into the upper computer (for example, the optical network terminal 100); the opening 204 is an optical port, which is configured to access the optical fiber 101 so that the optical fiber 101 is connected to the optical module 200.

[0134] The assembly method of combining the upper shell 201 and the lower shell 202 facilitates the installation of components such as the circuit board 300, the light emitting component 400 and the light receiving component 500 into the shell, and the upper shell 201 and the lower shell 202 form a package protection for these components. In addition, when assembling components such as the circuit board 300, the light emitting component 400 and the light receiving component 500, it is convenient to deploy the positioning components, heat dissipation components and electromagnetic shielding components of these components, which is conducive to the automated implementation of production.

[0135] In some embodiments, the upper shell 201 and the lower shell 202 are made of metal materials to facilitate electromagnetic shielding and heat dissipation.

[0208] FIG30 is a schematic diagram of the structure of the unlocking component and the lower shell in the optical module according to an embodiment of the present disclosure, and FIG31 is a schematic diagram of the exploded structure of the unlocking component and the lower shell in the optical module according to an embodiment of the present disclosure. Referring to FIG30 and FIG31, in order to facilitate the installation of the optical transceiver component and the circuit board and improve the compactness of the optical module structure, in some examples of the embodiments of the present disclosure, the lower shell 202 includes: a first wall 2021a and a second wall 2022a. Among them, the second wall 2022a is connected to one end of the first wall 2021a, and the second wall 2022a is recessed in the first wall 2021a. In the embodiments of the present disclosure, the locking portion 20221 (in some examples, it can also be called a locking component) can be provided on the second wall 2022a.

[0209] In some examples, it can also be understood that the first wall 2021a protrudes from the second wall 2022a, that is, one end of the lower shell 202 is thicker than the other end; in this way, the optical transceiver component can be set at the thicker end, for example, on the inner side of the first wall 2021a, and the circuit board itself is thinner and occupies less space, and can be set on the inner side of the second wall 2022a; in this way, the circuit board in the optical module has a compact structure in the shell; when connected to the host computer, the second wall 2022a can be inserted into the host computer, so that the space occupied by the host computer is relatively small.

[0210] In some optional examples of the embodiments of the present disclosure, the first wall 2021a and the second wall 2022a can be integrally formed, for example, can be integrally cast. Among them, the locking portion 20221 can be a protrusion on the second wall 2022a. In some examples, the locking portion 20221 and the second wall 2022a can also be integrally formed.

The ejector 602 may extend from the end of the body 601 toward the second wall 2022a, and the ejector 602 extends along the height direction of the lower shell 202 (for example, the direction shown in the negative direction of the z-axis in FIG. 6 ), so that the ejector 602 is tilted relative to the body 601. It can be understood that in some examples of the embodiments of the present disclosure, the unlocking component 600 may be a sheet metal part, so in some examples, the ejector 602 may be formed by bending one end of the unlocking component 600 facing the second wall 2022a, that is, the ejector 602 and the body 601 may be an integral structure; in this way, the processing and production of the unlocking component 600 is facilitated, and the processing and production cost of the unlocking component 600 is saved.

[0214] In some examples, the body 601, the ejector 602 and the force member 603 are an integrally formed structure, wherein the force member 603 can be formed by bending one end of the ejector 602 facing the second wall surface 2022a.

[0218] In some examples, the first wall surface 2021a includes a first bottom plate 20211, a first side plate 20212, and a second side plate 20213, and the first side plate 20212 and the second side plate 20213 are relatively arranged on both sides of the first bottom plate 20211. In some embodiments of the present disclosure, the outer surface of the first bottom plate 20211 is provided with a first recessed portion 20214 and a second recessed portion 20215, the second recessed portion 20215 is recessed in the first recessed portion 20214, the second recessed portion 20215 penetrates to the third wall surface 2023a, and the unlocking component is arranged in the second recessed portion 20215. In some examples, the first recessed portion 20214 can be located in the middle of the first recessed portion 20214 along the width direction of the first bottom plate 20211, and the second recessed portion 20215 is connected to the first recessed portion 20214. In some embodiments of the present disclosure, the unlocking component is disposed in the second recessed portion 20215, that is, in the embodiments of the present disclosure, the unlocking component is limited by the second recessed portion 20215. The width of the second recessed portion 20215 may be adapted to the width of the unlocking component, for example, the width of the second recessed portion 20215 may be equal to or similar to the width of the unlocking component. In some examples of the embodiments of the present disclosure, the body 601 may be located in the second recessed portion 20215.

[0219] In some embodiments, the first recessed portion 20214 includes a first sub-recessed portion 2141 and a second sub-recessed portion 2142, the first sub-recessed portion 2141 is connected to the second recessed portion 20215, the second sub-recessed portion 2142 extends to the third wall surface 2023a, and the second sub-recessed portion 2142 is connected to the first sub-recessed portion 2141, the second recessed portion 20215 and the third wall surface 2023a. In other words, the shape of the first recessed portion 20214 can be a "convex" shape, wherein the second sub-recessed portion 2142 is located between the first sub-recessed portion 2141 and the second wall surface 2022a.

[0220] In some examples of the embodiments of the present disclosure, the second recessed portion 20215 has a first bottom wall surface 2151 and a push-up wall surface 2152; the first bottom wall surface 2151 protrudes from the second wall surface 2022a; that is, there is still a certain height difference between the first bottom wall surface 2151 and the second wall surface 2022a. The push-up wall surface 2152 is connected between the first bottom wall surface 2151 and the second wall surface 2022a, and the push-up wall surface 2152 is inclined. The inclination of the push-up wall surface 2152 can be the same or similar to the inclination of the push-up member 602. In some specific examples, the push-up wall surface 2152 can be formed by chamfering the third wall surface 2023a between the first wall surface 2021a and the second wall surface 2022a (for example, cutting off the right angle formed after the second recessed portion 20215 penetrates to the third wall surface 2023a), thereby forming the push-up wall surface 2152.

[0221] Alternatively, in some examples, it can also be understood that a slope is formed between the first bottom wall surface 2151 and the second wall surface 2022a, and the first bottom wall surface 2151 and the second bottom wall surface 2156 are transitioned through the slope.

In the embodiment of the present disclosure, the push-up wall surface 2152 is an example of a straight wall surface for description.

[0223] In some examples, a first angle is defined between the ejection wall 2152 and the second wall 2022a, and a second angle is defined between the ejection member 602 and the second wall 2022a; wherein the first angle is greater than the second angle, so that when the unlocking member 600 moves toward the first wall 2021a, one end of the ejection member 602 facing the second wall 2022a abuts against the ejection wall 2152.

[0224] In some optional examples, the first angle may be 150°-160°, for example, the first angle may be 150°, 155° or 160°. The second angle may be 135°-150°, for example, the first angle may be 135°, 140°, 145° or 150°.

[0225] It should be noted here that the numerical values ​​and numerical ranges involved in the embodiments of the present disclosure are approximate values. Due to the influence of the manufacturing process, there may be a certain range of errors, which can be considered negligible by those skilled in the art.

[0226] In the embodiment of the present disclosure, the first angle between the push-up wall surface 2152 and the second wall surface 2022a is set to be greater than the second angle between the push-up member 602 and the second wall surface 2022a; in this way, when the unlocking component 600 moves toward the first wall surface 2021a, only the end of the push-up member 602 facing the side of the lower shell 202 contacts the push-up wall surface 2152, that is, the push-up member 602 and the push-up wall surface 2152 are in line-surface contact, so that the movement resistance and jitter caused by the uneven push-up wall surface 2152 or the push-up member 602 on the movement of the unlocking component can be effectively avoided, and the stability of the unlocking component unlocking the optical module can be improved. In some examples of the embodiments of the present disclosure, a limiting column 2153 is provided on the first bottom wall surface 2151; wherein the limiting column 2153 protrudes from the first bottom wall surface 2151. An accommodating through hole 6011 is provided on the unlocking component, and a limiting column 2153 is penetrated in the accommodating through hole 6011, and the limiting column 2153 is located at the end of the accommodating through hole 6011 facing away from the second wall surface 2022a; a positioning column 6012 is provided at the end of the accommodating through hole 6011 facing the second wall surface 2022a; in some embodiments of the present disclosure, a reset member 607 is provided in the accommodating through hole 6011, one end of the reset member 607 is connected to the positioning column 6012, and the other end of the reset member 607 is connected to the limiting column 2153; when the unlocking component moves away from the second wall surface 2022a, the reset member 607 provides a reset force facing the second wall surface 2022a to the unlocking component, so that when the external force on the unlocking component disappears, the reset member 607 drives the unlocking component to move toward the second wall surface 2022a.

[0227] Among them, the accommodating perforation 6011 can be obtained by digging holes or slotting the sheet metal. In some examples of the embodiments of the present disclosure, the reset member 607 can be an elastic member such as a spring, a sponge column, etc., one end of the elastic member abuts against the limiting column 2153, the elastic member extends along the extension direction of the accommodating perforation 6011, and the other end of the elastic member is connected to the positioning column 6012. In this way, when the unlocking component moves toward the first wall surface 2021a, the reset member 607 is compressed, thereby accumulating force; when the external force on the unlocking component disappears, the accumulated force of the reset member 607 is released, thereby pushing the unlocking component to move toward the second wall surface 2022a.

[0228] In some examples, the reset member 607 can also be two magnets with the same poles facing each other, one of which is set on the limit column 2153, and the other is set on the positioning column 6012. When the unlocking component moves toward the first wall 2021a, the distance between the two magnets with the same poles facing each other decreases and the repulsive force increases. When the external force on the unlocking component disappears, the repulsive force between the two magnets is released, thereby pushing the unlocking component to move toward the second wall 2022a.

[0229] In the embodiment of the present disclosure, a receiving hole 6011 is provided on the unlocking component, and a limiting column 2153 is provided on the first bottom wall 2151. The limiting column 2153 is passed through the receiving hole 6011, and the limiting column 2153 is located at the end of the receiving hole 6011 that is away from the second wall 2022a. In this way, when the reset member 607 is provided, the reset member 607 can be accommodated in the receiving hole 6011, which can reduce the size of the space occupied by the reset member 607, thereby facilitating the miniaturization of the optical module. In addition, the limiting column 2153 is arranged at the end of the accommodating through hole 6011 facing away from the second wall surface 2022a, and the positioning column 6012 is arranged at the end of the accommodating through hole 6011 facing the second wall surface 2022a. In this way, one end of the reset member 607 only needs to be sleeved on the outer periphery of the positioning column 6012, and the other end of the reset member 607 can be pressed against the limiting column 2153, which facilitates the installation of the reset member 607 and improves the assembly efficiency of the optical module.

[0230] In some other examples of the embodiments of the present disclosure, the second recessed portion 20215 further has a first limiting wall 2154 and a second limiting wall 2155, and the first limiting wall 2154 and the second limiting wall 2155 are relatively arranged on both sides of the first bottom wall 2151 along the width direction, and the first limiting wall 2154 is recessed to form a first limiting groove 21541, and the first sub-bottom wall 21542 of the first limiting groove 21541 is recessed in the first bottom wall 2151; the second limiting wall 2155 is recessed to form a second limiting groove 21551, and the second sub-bottom wall 21552 of the second limiting groove 21551 is recessed in the first bottom wall 2151; the first limiting groove 21541 and the second limiting groove 21551 are located on both sides of the limiting column 2153; the main body 601 is limited between the first limiting wall and the second limiting wall.

[0231] The first limiting groove 21541 and the second limiting groove 21551 can be arranged opposite to each other, wherein the width between the side walls of the first limiting groove 21541 and the second limiting groove 21551 is greater than the width between the first limiting wall surface 2154 and the second limiting wall surface 2155. As an optional example, the width between the first limiting wall surface 2154 and the second limiting wall surface 2155 can be adapted to the width of the body 601. Of course, in some examples, the widths of the body 601, the ejecting member 602 and the force applying member 603 can be the same, so that the unlocking member 600 can move in the second recessed portion 20215.

[0232] In some optional examples of the embodiments of the present disclosure, the outer surface of the first side plate 20212 is provided with a third recessed portion 2121, and the surface of the second side plate 20213 is provided with a fourth recessed portion 2131. The third recessed portion 2121 is recessed to form a plurality of first card slots 21211 arranged side by side, and the fourth recessed portion 2131 is recessed to form a plurality of second card slots 21311 arranged side by side. The third recessed portion 2121 is communicated with the first recessed portion 20214, and the fourth recessed portion 2131 is also communicated with the first recessed portion 20214.

[0233] In some embodiments of the present disclosure, the first card slot 21211 can be formed by punching the side wall of the third recessed portion 2121 inwardly, and the first card slot 21211 can be provided with two, three or four, etc. In the embodiments of the present disclosure, there is no restriction on the number of the first card slots 21211. Among them, the setting method of the second card slot 21311 can be the same as or similar to the first card slot 21211, which will not be repeated in the embodiments of the present disclosure. In some examples, the second card slot 21311 can be symmetrically arranged with the first card slot 21211, so that the positioning process when setting the first card slot 21211 and the second card slot 21311 can be reduced, thereby improving the processing efficiency.

[0234] In some other optional examples of the embodiments of the present disclosure, the second recessed portion 20215 further has a second bottom wall 2156, a third limiting wall 2157 and a fourth limiting wall 2158, the second bottom wall 2156 is located at the end of the first bottom wall 2151 facing away from the second wall 2022a, and the second bottom wall 2156 is recessed in the first bottom wall 2151; the third limiting wall 2157 and the fourth limiting wall 2158 are located on both sides of the second bottom wall 2156 along the width direction of the second bottom wall 2156, the third limiting wall 2157 is recessed in the first limiting wall 2154, and the fourth limiting wall 2158 is recessed in the second limiting wall 2155. That is to say, there is a certain height difference between the second bottom wall 2156 and the first bottom wall 2151 , and the width between the third limiting wall 2157 and the fourth limiting wall 2158 is greater than the width between the first limiting wall 2154 and the second limiting wall 2155 .

[0235] In some examples, there is a transition slope 2159 between the second bottom wall 2156 and the first bottom wall 2151. That is, the transition slope 2159 is not perpendicular to the first bottom wall 2151 and the second bottom wall 2156. In this way, the influence of the height difference between the first bottom wall 2151 and the second bottom wall 2156 on the movement of the rubber-coated handle can be reduced, and the smoothness of the unlocking component moving in the second recessed portion 20215 can be effectively improved.

[0236] To ensure that when the unlocking component is in a reset state, that is, the optical module and the host computer are in a locked state, the force-applying member 603 is located between the second wall 2022a and the locking spring sheet of the host computer, while reducing the overall size of the optical module, in some embodiments disclosed herein, along the width direction of the lower shell 202, sinking grooves 20223 are provided on both sides of the locking portion 20221, and the sinking grooves 20223 are recessed in the second wall 2022a, and the side wall of the sinking groove 20223 facing the first wall 2021a is a sloped wall 20224. In some examples, when the unlocking component 600 is in a reset state, the force-applying member 603 can sink into the sinking groove 20223.

[0237] By setting a sinking groove 20223 on both sides of the locking part 20221, the sinking groove 20223 is recessed in the second wall 2022a; in this way, when the unlocking component is in the reset state, the fourth bending portion sinks into the sinking groove 20223, so that the force-applying member 603 is integrally attached to the second wall 2022a, which can reduce the gap between the force-applying member 603 and the second wall 2022a, thereby reducing the gap between the locking spring sheet of the upper computer and the second wall 2022a, thereby improving the stability of the locking of the optical module and the upper computer.

[0238] In some embodiments of the present disclosure, the sloped wall 20224 is not perpendicular to the second wall 2022a and the bottom wall of the sinking groove 20223. In this way, a sloped wall 20224 is formed on the side of the sinking groove 20223 facing the first wall 2021a. When the unlocking component 600 moves toward the first wall 2021a, the force-applying member 603 moves from the inside to the outside of the sinking groove 20223 along the sloped wall 20224, which can reduce the movement resistance of the force-applying member 603 and improve the smoothness of the movement of the unlocking component 600.

[0239] In some examples, the inclined wall surface may be a straight inclined surface; or, in other examples, the sloped wall surface 20224 may also be an outwardly convex arc-shaped wall surface. The embodiments of the present disclosure do not limit the type of the inclined wall surface.

[0240] Figure 36 is a schematic diagram of the structure of the unlocking component in the optical module according to an embodiment of the present disclosure, and Figure 37 is another schematic diagram of the structure of the unlocking component in the optical module according to an embodiment of the present disclosure. In order to prevent the unlocking component 600 from being pulled out of the movable gap between the lower shell and the outer cover under the action of external force, referring to Figures 35-37, in the embodiment of the present disclosure, the unlocking component 600 also includes: a first limiting arm 604 and a second limiting arm 605.

[0241] The first limiting arm 604 protrudes from the main body 601, and the first limiting arm 604 is located on the side of the accommodating hole 6011, the first limiting arm 604 includes a first limiting extension arm 6041 and a first limiting bending arm 6042, the first limiting extension arm 6041 extends along the width direction of the main body 601 into the first limiting groove, and the first limiting bending arm 6042 is bent toward the first sub-bottom wall.

[0242] In some embodiments of the present disclosure, the dimension of the first limiting arm 604 along the length direction of the main body 601 is smaller than the dimension of the first limiting groove along the length direction of the second recessed portion, so that the first limiting arm 604 can move in the first limiting groove along the length direction.

[0243] In some embodiments of the present disclosure, the first limiting arm 604 is disposed on the side of the accommodating through hole 6011 , so that the first limiting arm 604 can widen the body 601 on the side of the accommodating through hole 6011 , thereby enhancing the strength of the body 601 .

[0244] In some examples of the embodiments of the present disclosure, part of the first limiting arm 604 can be bent toward the lower shell body 202 to form a first limiting extension arm 6041 and a first limiting bending arm 6042; in this way, the size of the first limiting arm 604 along the thickness direction of the main body 601 can be increased. When limiting the unlocking component 600, the first limiting bending arm 6042 can be blocked on the side wall of the first limiting groove facing away from the second wall, so that the size of the first limiting arm 604 along the thickness direction of the main body 601 is larger than the gap between the first sub-recess and the outer cover plate, thereby avoiding the unlocking component 600 from being pulled over. In addition, the size of the first limiting arm 604 along the thickness direction of the main body 601 is increased. In this way, when the unlocking component 600 is limited, the force area of ​​the first limiting arm 604 along the thickness direction of the main body 601 is increased, thereby improving the stability of the main body 601 in the thickness direction; when the main body 601 swings in the thickness direction, the first limiting bending arm 6042 can abut against the first sub-bottom wall surface, thereby improving the unlocking stability of the unlocking component 600.

[0245] It can be understood that in the embodiment of the present disclosure, the second position-limiting support arm 605 protrudes from the body 601, and the second position-limiting support arm 605 is located on the other side of the accommodating through hole 6011, and the second position-limiting support arm 605 includes a second position-limiting extension arm 6051 and a second position-limiting bending arm 6052, the second position-limiting extension arm 6051 extends into the second position-limiting groove along the width direction of the body 601, and the second position-limiting bending arm 6052 bends toward the second sub-bottom wall surface. In the embodiment of the present disclosure, the second position-limiting support arm 605 can be arranged in the same or similar manner as the first position-limiting support arm 604, and the detailed description of the first position-limiting support arm 604 can be referred to, and the embodiment of the present disclosure will not be repeated.

[0246] In addition, in the embodiment of the present disclosure, the first limiting arm 604 and the second limiting arm 605 can be symmetrically arranged relative to the accommodating hole 6011; in this way, the unlocking component 600 can be provided with stable limiting by the symmetrical first limiting arm 604 and the second limiting arm 605, thereby preventing the unlocking component 600 from shaking in the second recessed portion.

[0247] In some embodiments of the present disclosure, when the unlocking component 600 moves toward the first wall surface 2021a to the second preset position, the first limiting arm 604 abuts against the wall surface of the first limiting groove on the side facing away from the second wall surface, and the second limiting arm 605 abuts against the wall surface of the second limiting groove on the side facing away from the second wall surface, so as to limit the moving stroke of the unlocking component 600. In this way, it is possible to avoid the unlocking component 600 from excessively moving in the second recessed portion, causing fatigue of the reset component 607, and effectively prolonging the service life of the reset component 607, that is, prolonging the effective unlocking times of the unlocking component 600.

[0248] In some examples of the embodiments of the present disclosure, the force applying member 603 has two unlocking arms 6031 extending along the second wall surface. The two unlocking arms 6031 are arranged side by side along the width direction of the lower shell, and an avoidance gap 6032 is provided between the two unlocking arms 6031, and the avoidance gap 6032 is used to avoid the locking part. When the optical module and the host computer are in a locked state, the locking part is inserted into the avoidance gap 6032, and the two unlocking arms 6031 are located on both sides of the locking part.

[0249] In some examples, the force member 603 has a fourth bending portion 60311, and the fourth bending portion 60311 is bent from one end of the force member 603 facing away from the body 601 toward the second wall surface, and the fourth bending portion 60311 is attached to the side of the force member 603 facing the second wall surface. In some examples, the fourth bending portion 60311 can be formed by bending a portion of the unlocking arm 6031 toward the second wall surface. In some embodiments of the present disclosure, by providing the fourth bending portion 60311, the strength of the force member 603 can be improved, ensuring that the force member 603 will not bend and deform during the unlocking process, thereby ensuring the effectiveness of the unlocking component 600 in unlocking the optical module. Among them, when the unlocking component 600 is in the reset state, the fourth bending portion 60311 can sink into the sinking groove.

[0250] Fig. 38 is another structural schematic diagram of an unlocking component in an optical module according to an embodiment of the present disclosure. Referring to Fig. 38, in the embodiment of the present disclosure, the unlocking component 600 further includes a rubber-coated handle 606, one end of which is coated on the end of the body 601 facing away from the second wall surface; the other end of the rubber-coated handle 606 extends to the outside of the second recessed portion, and the rubber-coated handle 606 is limited between the third limiting wall surface and the fourth limiting wall surface.

[0251] It can be understood that in the embodiment of the present disclosure, a portion of the rubber-coated handle 606 may be limited between the third limiting wall and the fourth limiting wall. Another portion of the rubber-coated handle 606 extends to the side of the first wall facing away from the second wall. When the optical module needs to be pulled out or extracted from the host computer, the rubber-coated handle 606 can be pulled, so that the rubber-coated handle 606 drives the body 601, the ejector 602 and the force-applying member 603 of the unlocking component to move toward the first wall.

[0252] In some embodiments of the present disclosure, since the rubber-coated handle 606 is coated on the end of the main body 601 facing away from the second wall, the size of the rubber-coated handle 606 is slightly larger than the size of the main body 601; the width dimension between the third limiting wall and the fourth limiting wall is set to be larger than the width dimension between the first limiting wall and the second limiting wall, so that the rubber-coated handle 606 can be matched with the clearance between the third limiting wall and the fourth limiting wall, thereby reducing the friction force on the rubber-coated handle 606 and improving the smoothness of the movement of the unlocking component 600 in the second recessed portion when unlocking.

[0253] Since the second bottom wall is recessed in the first bottom wall, the second bottom wall is relatively thin and difficult to process during production. In order to avoid forming a larger through hole at the second bottom wall and to avoid the rubber-coated handle 606 from entering the lower shell and interfering with the lower shell, causing the unlocking component 600 to move unsmoothly, in some examples of the embodiments of the present disclosure, a fiber optic adapter mounting structure is provided in the lower shell, and the fiber optic adapter mounting structure is located on the side of the second bottom wall facing the first bottom wall, so that the side of the second bottom wall facing the first bottom wall is a closed bottom wall.

[0254] That is to say, in some embodiments of the present disclosure, part of the second bottom wall surface can be thickened by means of the optical adapter mounting structure in the lower shell body, and when the second bottom wall surface is recessed in the first bottom wall surface, the part of the second bottom wall surface provided with the optical adapter mounting structure forms a closed bottom wall surface; in this way, the opening area of ​​the through hole formed in the second bottom wall surface can be reduced, thereby avoiding the interference between the rubber-coated handle 606 and the lower shell body, and improving the smoothness of the movement of the unlocking component 600 in the second recessed portion.

[0255] In order to facilitate the connection between the external optical fiber (e.g., the optical connector of the external optical fiber) and the optical fiber adapter of the optical port, in some examples of the embodiments of the present disclosure, the rubber-coated handle 606 is a soft part. For example, the rubber-coated handle 606 can be made of silicone, soft plastic or soft rubber materials. In this way, when the optical connector of the external optical fiber is inserted into the optical fiber adapter, the rubber-coated handle 606 can be bent, thereby facilitating the connection between the optical fiber adapter and the external optical fiber connector.

[0256] As an optional example, a pull ring may be provided on the end of the rubber-coated handle 606 extending to the lower shell facing away from the upper computer. The pull ring may be in the shape of a circular hole, an elliptical hole or other special-shaped hole structures, which is not limited in the embodiments of the present disclosure.

[0257] FIG39 is a cross-sectional view of an unlocking component in an optical module according to an embodiment of the present disclosure, FIG40 is a partial enlarged view of B in FIG39, and FIG41 is a schematic diagram of an exploded structure of the lower housing, the unlocking component and the outer cover plate in the optical module according to an embodiment of the present disclosure. Referring to FIGS. 39-41, in order to enhance the connection strength between the rubber-coated handle 606 and the body 601, increase the force area of ​​the rubber-coated handle 606, and change the force direction of the rubber-coated handle 606, and avoid the rubber-coated handle 606 from falling off or breaking off from the body 601, in some embodiments of the present disclosure, a plurality of notches 6013 are provided at one end of the body 601 facing away from the second wall, and the notches 6013 extend along the width direction of the body 601, and the plurality of notches 6013 are arranged along the length direction of the body 601. In some embodiments of the present disclosure, the notch 6013 may be a through hole, and in some examples, the notch 6013 may also be a groove. In some embodiments of the present disclosure, the notch 6013 is described as a through hole as an example. Part of the rubber-coated handle 606 is embedded in the notch 6013. In a specific configuration, the rubber-coated handle 606 can be injected into a mold with the body 601 when it is in a molten state (liquid state), and the liquid rubber is filled into the notch 6013, and the parts located on both sides of the body 601 are connected through the parts in the notch 6013 to form an integral part. In this way, after the rubber-coated handle 606 is connected to the body 601, the force-bearing area of ​​the rubber-coated handle 606 and the strength of the rubber-coated handle 606 are increased, which can effectively prevent the rubber-coated handle 606 from being pulled off, and the force between the rubber-coated handle 606 and the body 601 is converted from the friction force on the surface to the pulling force in the notch 6013, which can increase the force of the rubber-coated handle 606 on the main body 601, and can prevent the rubber-coated handle 606 from falling off from the body 601.

[0258] In some embodiments of the present disclosure, the thickness of the portion of the rubber-coated handle 606 coated on the body 601 is greater than the thickness of the end of the rubber-coated handle 606 facing away from the second wall. In this way, on the one hand, the strength of the connection between the rubber-coated handle 606 and the body 601 can be enhanced, and on the other hand, the material of the rubber-coated handle 606 can be saved, reducing the processing and production costs.

[0259] FIG42 is a schematic diagram of a structure of an outer cover plate in an optical module according to an embodiment of the present disclosure, FIG43 is another schematic diagram of a structure of an outer cover plate in an optical module according to an embodiment of the present disclosure, FIG44 is another schematic diagram of a structure of an outer cover plate in an optical module according to an embodiment of the present disclosure, and FIG45 is a partial enlarged view of C in FIG44. Referring to FIG41-FIG45, the outer cover plate 700 includes: a first protruding portion 701, a cover plate body 702 and a first extending portion 703; wherein the first protruding portion 701 includes: a first bending portion 7011 and a second bending portion 7012.

[0260] In some examples, the outer cover 700 may be made of sheet metal, wherein the cover body 702 may be covered on the first wall 2021 a and located on the side of the unlocking component facing away from the lower shell 202 .

[0261] The first extension portion 703 may extend from one end of the cover body 702 to the second wall surface. For example, the first extension portion 703 may be arranged at one end of the cover body 702 facing the second wall surface. In some examples, the first extension portion 703 and the cover body 702 may be an integral part. For example, the sheet metal part may be cut and processed to form the first extension portion 703. Among them, the first bending portion 7011 may have one end of the first extension portion 703 facing the second wall surface (i.e., the end facing away from the cover body 702) bent toward the lower shell 202 (usually also understood as bending toward the inner side of the cover body 702); in some embodiments of the embodiments of the present disclosure, the first bending portion 7011 is attached to the inner wall surface of the first extension portion 703. In this way, the space occupied by the first bending portion 7011 can be reduced, which facilitates the arrangement of the second bending portion 7012.

[0262] In some embodiments of the present disclosure, the second bending portion 7012 is bent from the first bending portion 7011 toward the lower shell 202 , and the second bending portion 7012 can serve as the first protruding portion 701 .

[0263] That is to say, in some embodiments of the present disclosure, the first protrusion 701 and the outer cover plate 700 may be an integral structure, that is, the sheet metal is cut and bent to form the first protrusion 701. In this way, since the first protrusion 701 is formed by bending the sheet metal, the first protrusion 701 has a certain elasticity, which can improve the smoothness of the reset of the unlocking component.

[0264] In the embodiment of the present disclosure, the cover plate body 702, the first extension portion 703, the first bent portion 7011 and the second bent portion 7012 are formed by cutting and bending the sheet metal parts to provide abutment when the unlocking component is reset; in this way, the processing and forming of the first protrusion 701 is facilitated, and the processing and production cost of the first protrusion 701 is effectively saved.

[0265] In some examples of the embodiments of the present disclosure, the second bending portion 7012 includes: a first sub-bending segment 70121 and a second sub-bending segment 70122. The first sub-bending segment 70121 is bent from the first bending portion 7011 toward the lower housing 202. That is, in the embodiments of the present disclosure, after the first bending portion 7011 is bent and attached to the inner wall surface of the first extension portion 703, the end of the first bending portion 7011 continues to bend toward the direction of the lower housing 202, thereby forming the first sub-bending segment 70121. In the embodiment of the present disclosure, the second sub-bending section 70122 is bent from the first sub-bending section 70121 toward the lower shell body 202; that is, the end of the first sub-bending section 70121 is toward the lower shell body, and the head end of the second sub-bending section 70122 is also toward the lower shell body, and the end of the second sub-bending section is toward the inner wall surface of the outer cover plate 700; in this way, an arc-shaped bending portion 70123 is formed at the connection between the first sub-bending section 70121 and the second sub-bending section 70122, and when the unlocking component moves toward the second wall surface 2022a, the arc-shaped bending portion 70123 abuts against the pushing member.

[0266] In some embodiments of the present disclosure, the second bending portion 7012 is set to two sub-bending sections, wherein the first sub-bending section 70121 is bent toward the lower shell body, and the second sub-bending section 70122 is bent away from the lower shell body; in this way, an arc-shaped bending portion 70123 is formed at the connection between the first sub-bending section 70121 and the second sub-bending section 70122; the pushing member is pushed against by the arc-shaped bending portion 70123, so that the contact portion between the first protrusion 701 and the pushing member is smoother, which can effectively prevent the pushing member from being scratched, thereby improving the smoothness of the reset of the unlocking component and preventing the unlocking component from getting stuck.

[0267] In some examples of the embodiments of the present disclosure, the width of the first extension portion 703 is smaller than the width of the cover body 702, and the width of the second bent portion 7012 is smaller than the width of the first bent portion 7011. That is, in some embodiments of the present disclosure, when the first extension portion 703 is formed at one end of the cover body 702 facing the second wall, the sheet metal part can be cut to form the first extension portion 703, so that the width of the first extension portion 703 is smaller than the width of the cover body 702. In this way, it is convenient to bend the first extension portion 703 to form the first bent portion 7011, and the stress when the first extension portion 703 is bent can be reduced. In addition, when the first bending portion 7011 is bent to form the second bending portion 7012, the side of the first bending portion 7011 can be cut again so that the width of the second bending portion 7012 is smaller than the width of the first bending portion 7011; in this way, when the second bending portion 7012 is bent, the stress when bending the second bending portion 7012 can be reduced.

[0268] In addition, when the outer cover plate 700 is installed on the first wall, the cover plate body 702 is embedded in the first sub-recessed portion, and the outer wall surface of the cover plate body 702 is flush with the first wall surface, the first extension portion 703 is embedded in the second sub-recessed portion, and the outer wall surface of the first extension portion 703 is flush with the first wall surface; the second bending portion 7012 can be embedded in the second recessed portion. The side wall surface of the first extension portion 703 can contact the side wall surface of the second sub-recessed portion, so that the second sub-recessed portion can be used to limit the first extension portion 703.

[0269] As an optional example, the width of the second bent portion 7012 can be slightly smaller than the width of the second recessed portion. In this way, when the outer cover 700 is installed on the first wall, the second bent portion 7012 is embedded in the second recessed portion and cooperates with the gap between the side wall of the second recessed portion, which facilitates the installation of the outer cover 700 and improves the installation efficiency of the outer cover 700.

[0270] In some embodiments of the present disclosure, a first recessed portion is provided on the first wall surface, and the first recessed portion is provided to include a first sub-recessed portion and a second sub-recessed portion; thus, the cover body 702 can be embedded in the first sub-recessed portion, and the first extension portion 703 can be embedded in the second sub-recessed portion, so that the surface of the outer cover 700 can be flush with the first wall surface, thereby maintaining the overall flatness of the outer surface of the optical module. In some embodiments of the present disclosure, the second bending portion 7012 has a first side wall surface 70124 and a second side wall surface 70125 that are opposite to each other along the width direction; as shown in Figure 20, the first bending portion 7011 has a third side wall surface 70111 and a fourth side wall surface 70112; a first notch 70113 is provided between the third side wall surface 70111 and the first side wall surface 70124, and a second notch 70114 is provided between the fourth side wall surface 70112 and the second side wall surface 70125. The first notch 70113 and the second notch 70114 are used to release the bending stress between the second bending portion 7012 and the first bending portion 7011.

[0271] In some examples, after cutting the two side edges of the first bending portion 7011, the first side wall surface 701244 of the second bending portion 7012 can continue to be cut toward the first bending portion 7011 to form a first notch 70113, wherein the processing and forming method of the second notch 70114 can be the same or similar to that of the first notch 70113, and the embodiments of the present disclosure will not be repeated here.

[0272] In the embodiment of the present disclosure, the width of the first extension portion 703 is set to be smaller than the width of the cover body 702, the width of the second bending portion 7012 is set to be smaller than the first bending portion 7011, and a first notch 70113 is set between the first side wall surface 70124 of the second bending portion 7012 and the third side wall surface 70111 of the first bending portion 7011, and a second notch 70114 is set between the second side wall surface 70125 and the fourth side wall surface 70112; in this way, when the second bending portion 7012 is bent to form, the first notch 70113 and the second notch 70114 can release the stress generated by the bending of the second bending portion 7012, thereby facilitating the bending and forming of the second bending portion 7012, and can effectively protect the first bending portion 7011 from being torn by the stress generated by the bending of the second bending portion 7012; that is, it is convenient for the processing and forming of the first bending portion 7011 and the second bending portion 7012, thereby ensuring the structural integrity of the outer cover 700.

[0273] In some examples of the embodiments of the present disclosure, the outer cover 700 further includes a second extension portion 704 and a third bending portion 705. The second extension portion 704 is located at one end of the cover body 702 facing away from the second wall surface, the second extension portion 704 extends away from the second wall surface, the width of the second extension portion 704 is smaller than the cover body 702, and the second extension portion 704 is limited between the third limiting wall surface and the fourth limiting wall surface; the third bending portion 705 is bent toward the lower shell from one end of the second extension portion 704 facing away from the second wall surface, and the third bending portion 705 is attached to the inner wall surface of the second extension portion 704; the width of the third bending portion 705 is greater than the width of the second extension portion 704, so that the end of the third bending portion 705 contacts the inner wall surface of the cover body 702. It should be noted here that the width of the third bending portion 705 and the width of the second extension portion 704 can refer to the dimensions along the length direction of the lower shell. In some embodiments of the present disclosure, the width of the third bending portion 705 is set to be greater than the width of the second extending portion 704. This facilitates bending and forming the third bending portion 705, improves the convenience of processing and production, and improves the yield rate of optical module products.

[0274] In some examples, the length dimension of the second extension portion 704 can be slightly smaller than the width between the third limiting wall and the fourth limiting wall; in this way, the second extension portion 704 can be easily embedded between the third limiting wall and the fourth limiting wall, and limit the installation of the outer cover 700, for example, limiting the outer cover 700 along the width direction of the lower shell.

[0275] In addition, in some embodiments of the present disclosure, the second extension portion 704 can be covered on the side of the rubber-coated handle facing away from the lower shell body, thereby limiting the rubber-coated handle. That is to say, in the embodiments of the present disclosure, the second extension portion 704 can also play a certain limiting role on the rubber-coated handle in the direction facing away from the lower shell body.

[0276] Furthermore, in some embodiments of the present disclosure, a third bending portion 705 is formed by bending the end of the second extension portion 704. Thus, a bent arc is formed at the end of the second extension portion 704 facing away from the second wall surface. This can prevent burrs or burrs from forming at the end of the second extension portion 704. The end of the second extension portion 704 is in an arc shape. This can prevent scratches on other components. Furthermore, when assembling an external optical fiber connector, the rubber-coated handle is bent toward the second extension portion 704. This can also prevent scratches on the rubber-coated handle, thereby effectively extending the service life of the rubber-coated handle.

[0277] In other examples of the embodiments of the present disclosure, the outer wall surface of the cover body 702 is recessed to form a recessed groove 7021, and the recessed groove 7021 is used to accommodate a label, and the depth of the recessed groove 7021 is greater than the thickness of the label. In the embodiments of the present disclosure, the recessed groove 7021 can be obtained by stamping the cover body 702. In some examples, the recessed groove 7021 can also be obtained by cold rolling, and the embodiments of the present disclosure are not limited to this. In some embodiments of the present disclosure, the label can be attached to the recessed groove 7021, and the thickness of the label is usually 0.2mm; in some embodiments of the present disclosure, the depth of the recessed groove 7021 can be 0.4mm-0.5mm. In this way, the label sinks into the recessed groove 7021, and during the transportation, transshipment, transfer or use of the optical module, the label can be prevented from being hung up, thereby protecting the label.

[0278] In some examples of the embodiments of the present disclosure, the inner wall surface of the cover body 702 is protruded to form a second protruding portion 7022 corresponding to the concave groove 7021, and the protruding height of the second protruding portion 7022 is greater than the thickness of the third bent portion 705. It can be understood that in some embodiments of the present disclosure, when the concave groove 7021 is formed by stamping the cover body 702, the second protruding portion 7022 is formed on the opposite side of the concave groove 7021; in this way, the second protruding portion 7022 can enhance the strength of the cover body 702. When the unlocking component moves toward the first wall, due to the setting of the push-up member, the unlocking component simultaneously moves away from the lower shell body (i.e. facing the outer cover plate 700). When the unlocking component moves to the unlocking position, the unlocking component abuts against the inner wall of the outer cover plate 700. In the embodiment of the present disclosure, a second protrusion 7022 is formed on the inner wall of the outer cover plate 700. In this way, the second protrusion 7022 abuts against the unlocking component, thereby preventing the unlocking component from pushing the outer cover plate 700 against the outer cover plate 700 and deforming it.

[0279] In some examples, the outer cover plate 700 also includes a third side plate 706 and a fourth side plate 707, the inner surface of the third side plate 706 protrudes to form a plurality of first buckles 7061 arranged side by side, and the inner surface of the fourth side plate 707 protrudes to form a plurality of second buckles 7071 arranged side by side; the third side plate 706 is embedded in the third recessed portion, and the first buckle 7061 is clamped in the first clamping groove; the fourth side plate 707 is embedded in the fourth recessed portion, and the second buckle 7071 is clamped in the second clamping groove.

[0280] In some embodiments of the present disclosure, the first card slot can be formed by punching the side wall of the third recessed portion inwardly, and the first card slot can be provided with two, three or four, etc. In the embodiments of the present disclosure, there is no restriction on the number of the first card slots. Among them, the setting method of the second card slot can be the same as or similar to the first card slot, which will not be repeated in the embodiments of the present disclosure. In some examples, the second card slot can be symmetrically arranged with the first card slot, so that the positioning process when setting the first card slot and the second card slot can be reduced, thereby improving the processing efficiency.

[0281] Correspondingly, the first buckle 7061 can also be stamped out by the third side plate 706, and the number of the first buckles 7061 can be the same as the number of the first slots; in addition, the setting method of the second buckle 7071 can also be the same as or similar to the first buckle 7061, which will not be repeated in the embodiments of the present disclosure.

[0282] In some embodiments of the present disclosure, when assembling the outer cover plate 700, the third side plate 706 can be inserted into the third recessed portion, the fourth side plate 707 can be inserted into the fourth recessed portion, and the first clip 7061 can be inserted into the first slot, and the second clip 7071 can be inserted into the second slot, thereby improving the installation and assembly efficiency of the outer cover plate 700.

[0283] In some examples, the wall surface of the third side plate 706 contacts the wall surface of the third recessed portion, and the wall surface of the fourth side plate 707 contacts the wall surface of the fourth recessed portion, thereby limiting the outer cover plate 700 and improving the stability of the installation of the outer cover plate 700.

[0284] In other examples, the thickness of the third side panel 706 is the same as or similar to the depth of the third recess, so that when the third side panel 706 is inserted into the third recess, the outer wall surface of the third side panel 706 is flush with the outer wall surface of the first side panel; correspondingly, the thickness of the fourth side panel 707 is the same as or similar to the depth of the fourth recess, so that when the fourth side panel 707 is inserted into the fourth recess, the outer wall surface of the fourth side panel 707 is flush with the outer wall surface of the second side panel, thereby improving the flatness of the surface of the optical module.

[0285] FIG46 is a cross-sectional view of the unlocking component and the lower shell in the optical module according to an embodiment of the present disclosure, FIG47 is a partial enlarged view of D in FIG46, FIG48 is a partial enlarged view of the unlocking component in the optical module according to an embodiment of the present disclosure when it moves to a preset position, FIG49 is another cross-sectional view of the unlocking component and the lower shell in the optical module according to an embodiment of the present disclosure, and FIG50 is a partial enlarged view of E in FIG49. Referring to FIGS. 46-50, in some examples of the embodiments of the present disclosure, when it is necessary to pull out or extract the optical module from the host computer, the unlocking component can be moved toward the first wall surface 2021a. For example, referring to FIG46, the unlocking component 600 can be moved along the negative direction of the x-axis in FIG46, and at this time, the ejector 602 moves from the second wall surface 2022a to the first wall surface 2021a. That is, when the optical module is inserted into the host computer and the optical module and the host computer are in a locked state, the ejector 602 can be located on the second wall surface 2022a, or part of the ejector 602 is located on the second wall surface 2022a; when the unlocking component 600 moves toward the first wall surface 2021a, the ejector 602 moves from the second wall surface 2022a to the first wall surface 2021a. In some examples, the ejector 602 can be completely moved to the first wall surface 2021a, or part of it can be moved to the first wall surface 2021a.

[0286] In some embodiments of the present disclosure, the first wall surface 2021a protrudes from the second wall surface 2022a. When the ejector 602 moves from the second wall surface 2022a to the first wall surface 2021a, the step formed between the first wall surface 2021a and the second wall surface 2022a (for example, the ejector wall surface 2152 described in detail in the previous embodiment of the present disclosure) abuts against the surface of the ejector 602 facing the lower housing 202. In this way, the ejector 602 is subjected to the force of the ejector 602, thereby raising the height of the ejector 602. At this time, the entire unlocking component 6 moves back to the lower housing 202 under the drive of the ejector 602. For example, as shown in FIG. 46, the entire unlocking component 600 moves in the direction shown in the positive direction of the y-axis in FIG. 46. For example, it moves from the state shown in FIG. 46 to the state shown in FIG. 50.

[0287] In some embodiments of the present disclosure, the force member 603 is connected to one end of the push member 602 facing the locking portion. In some embodiments of the present disclosure, the force member 603 can be parallel or approximately parallel to the second wall 2022a. It can be understood that when the unlocking component moves toward the first wall 2021a, due to the interaction between the push member 602 and the push wall 2152 between the first wall 2021a and the second wall 2022a, the entire unlocking component moves back toward the lower shell 202 under the drive of the push member 602; at this time, the force member 603 moves back toward the second wall 2022a, thereby pushing the locking spring on the upper computer cage away from the locking portion 20221, thereby unlocking the optical module and the upper computer.

[0288] In some optional examples of the embodiments of the present disclosure, due to the setting of the push-up member 602, when the unlocking member 600 moves toward the first wall 2021a, the unlocking member 600 is pushed by the push-up member 602 as a whole and moves back toward the lower shell body; to ensure that when the optical module is inserted into the upper computer, the force-applying member 603 is located between the locking spring piece of the upper computer and the second wall 2022a, in some embodiments of the present disclosure, a first protrusion 701 is provided on the side of the outer cover plate 700 facing the push-up member 602; when the unlocking member 600 moves toward the second wall to a first preset position (for example, along the position shown in FIG. 48), the first protrusion 701 contacts the push-up member 602 to move the unlocking member 600 toward the lower shell body, and when the unlocking member 600 is in a reset state, the first protrusion 701 is interference fit with the unlocking member 600.

[0289] That is to say, in some embodiments of the present disclosure, after the unlocking component 600 unlocks the optical module and the host computer, the unlocking component 600 first moves along the length direction of the first wall 2021a or the second wall 2022a during the process of moving and resetting to the second wall 2022a; when the unlocking component 600 moves to the first preset position, the ejecting member 602 contacts the first protrusion 701, and since the ejecting member 602 is inclined, the force of the first protrusion 701 on the ejecting member 602 can be decomposed into a force vertically directed to the lower shell 202 and a force along the length direction of the lower shell 202; at this time, the unlocking component 600 continues to move along the length direction of the lower shell 202 under the action of the resetting force, and the force of the first protrusion 701 on the ejecting member 602 pushes the entire unlocking component 600 to move toward the lower shell 202, thereby making the force-applying member 603 fit onto the second wall 2022a.

[0290] In some examples, the first protrusion 701 may be a convex strip, a convex rib or a spring sheet, etc., provided on the inner wall of the outer cover plate 700. The first protrusion 701 may extend along the width direction of the outer cover plate 700; wherein the length of the first protrusion 701 may match the width of the unlocking component, for example, the length of the first protrusion 701 may be the same, close or similar to the width of the unlocking component.

[0291] In some possible examples, when the unlocking component is in the reset state, the first protrusion 701 can abut against the top end of the ejection member that is connected to the body 601. In this way, when the unlocking component is in the reset state, the first protrusion 701 and the unlocking component can be in an interference fit state, so that the force applying member 603 is completely attached to the second wall surface.

[0292] The optical module provided by the embodiment of the present disclosure forms a housing cavity by covering the upper shell and the lower shell, and arranges the circuit board and the optical transceiver component in the housing cavity, which is convenient for the arrangement of the circuit board and the optical transceiver component and improves the installation and assembly efficiency of the optical module; a first wall surface and a second wall surface are arranged on the lower shell, the second wall surface is recessed in the first wall surface, and a locking portion is arranged on the second wall surface; in this way, when the optical module is inserted into the upper computer, the locking portion on the second wall surface establishes a locking relationship with the outside, for example, it is locked with the locking structure on the cage of the upper computer; the embodiment of the present disclosure In the example, the body of the unlocking component is arranged on the first wall surface, the pushing member of the unlocking component is arranged obliquely relative to the body, and the force-applying member is arranged at one end of the pushing member facing the locking portion; in this way, when the optical module needs to be pulled out from the upper computer, the unlocking component can be moved in the direction of the first wall surface, the pushing member moves from the second wall surface to the first wall surface, and pushes the unlocking component as a whole to move back toward the lower shell body, so that the force-applying member pushes the locking structure on the cage of the upper computer away from the locking portion, thereby unlocking the locking portion; in addition, an outer cover plate is arranged on the first wall surface, and the outer cover plate is arranged on the The unlocking component faces away from the side of the lower shell body, so that the outer cover plate limits the unlocking component on the lower shell body and moves along the length direction of the lower shell body, and a movable gap of the unlocking component is left between the outer cover plate and the lower shell body, so that when the unlocking component moves toward the first wall surface, the push-out member moves from the second wall surface to the first wall surface, thereby pushing the entire unlocking component in the direction away from the lower shell body, that is, it is convenient for the force-applying member to apply a force to the locking structure of the upper machine cage; in the embodiment of the present disclosure, a first protrusion is provided on the side of the outer cover plate facing the push-out member, and the first protrusion can selectively abut against the push-out member during the process of the unlocking component moving and resetting toward the second wall surface, so that the first protrusion has a force facing the lower shell body on the push-out member, so that the unlocking component moves toward the lower shell body while resetting to the second wall surface, so that the force-applying member can move on the second wall surface during the resetting process of the unlocking component from the first preset position, so that the force-applying member is inserted into the lower side of the locking structure of the upper machine cage, so that the unlocking component is normally reset, and is successfully unlocked at the next unlocking, thereby improving the smoothness and stability of the unlocking of the unlocking component.

[0293] In some examples of the embodiments of the present disclosure, when the unlocking component moves toward the first wall surface to the first preset position (for example, as shown in FIG. 22, the first preset position may be the position where the ejecting member 602 begins to contact the ejecting wall surface 2152), the ejecting member 602 is separated from the first protruding portion 701, and when the unlocking component continues to move toward the first wall surface, there is a certain gap between the ejecting member 602 and the first protruding portion 701. That is to say, in some embodiments of the present disclosure, when the unlocking component moves toward the first wall surface to the first preset position, the force between the first protruding portion 701 and the ejecting member 602 is zero, and the unlocking component continues to move a certain distance to reach the unlocking position, and the force-applying member 603 completely unlocks the optical module from the host computer.

[0294] When the unlocking component moves toward the second wall to the first preset position, the first protrusion 701 contacts the push-up member 602 to move the unlocking component 600 toward the lower shell body, and when the unlocking component is in a reset state, the vertical distance between the first protrusion 701 and the second wall is smaller than the vertical distance between the surface of the main body 601 facing away from the second wall and the second wall.

[0295] That is to say, when the unlocking component 600 is in the reset state, at least one of the first protrusion 701 and the unlocking component may undergo a certain deformation; for example, the first protrusion 701 may have a certain deformation with its back facing the lower shell body; in some examples, since the unlocking component is supported by sheet metal, the unlocking component may also have a certain deformation; or, in other examples, both the first protrusion 701 and the unlocking component may undergo a certain deformation.

[0296] In the embodiment of the present disclosure, the push-up member 602 is configured to separate from the first protrusion 701 when the unlocking member moves toward the first wall to the first preset position, and when the unlocking member moves toward the second wall to the first preset position, the first protrusion 701 contacts the push-up member 602, so that the unlocking member moves toward the lower shell body, and when the unlocking member is in a reset state, the vertical distance between the first protrusion 701 and the second wall is smaller than the vertical distance between the surface of the body 601 facing away from the second wall and the second wall; in this way, when the optical module and the upper computer are in a locked state or the unlocking member is in a reset state, the unlocking member 600 can be subjected to the pressing force directed to the lower shell body by the first protrusion 701, so that the unlocking member and the lower shell body fit together, which facilitates the stable locking of the optical module and the upper computer.

[0299] 51 , the first lower side plate 2022b may be provided with a first recessed area 210. The first recessed area 210 is recessed toward the inner cavity of the wrapping cavity, so that the first recessed area 210 is recessed in the first lower side plate 2022b.

[0300] The first lower side plate 2022b may be provided with a first locking slot 2028b that is recessed inwardly of the first lower side plate 2022b and communicates with the first recessed area 210 .

[0301] In some embodiments, the unlocking component 600 may include an unlocker 620b. The unlocker 620b is installed on the outer side of the lower housing 202, and one end of the unlocker 620b is embedded in the first recessed area 210 and the first locking slot 2028b on the first lower side plate 2022b.

[0302] After one end of the unlocker 620b is embedded in the first recessed area 210 and the first locking slot 2028b, one end of the unlocker 620b is recessed in the first lower side plate 2022b to facilitate embedding the locking plate of the cage 106 in the recessed area of ​​the unlocker 620b, thereby fixing the optical module 200 and the cage 106 through the locking plate.

[0303] 52 and 53 , the unlocking component 600 may include a handle 610 b (in some examples, the gripping portion may include the handle 610 b ). The handle 610 b is connected to the unlocking device 620 b , and the operator may grasp the handle 610 b to push the unlocking component 600 inward, thereby inserting the optical module 200 into the cage 106 , and locking the optical module 200 and the cage 106 .

[0304] Alternatively, the operator may grasp the handle 610 b to pull the unlocking component 600 outward, thereby pulling the optical module 200 out of the cage 106 , thereby unlocking the optical module 200 and the cage 106 .

[0305] In some embodiments, a gripping hole 611b (also referred to as a through hole 611 in some examples) may be formed on the handle 610b. The gripping hole 611b runs through the handle 610b, and the operator can push the unlocker 620b inward by gripping the gripping hole 611b, or pull the unlocker 620b outward by gripping the gripping hole 611b.

[0342] The fourth inclined surface 6222 is inclined toward the second lower side plate 2023b, so that the fourth inclined surface 6222 is inclined from inside to outside.

[0343] In some embodiments, when the third inclined surface 6221 is inclined from outside to inside and the fourth inclined surface 6222 is inclined from inside to outside, the third inclined surface 6221 and the fourth inclined surface 6222 form a second groove, which is a V-shaped groove.

[0345] When the second unlocking arm 622 is installed on the second lower side plate 2023b, the second unlocking arm 622 is installed on the bearing surface on the second lower side plate 2023b, the third inclined surface 6221 and the fourth inclined surface 6222 are located in the third recessed area of ​​the second lower side plate 2023b, and the second locking hook 6223 is embedded in the second locking slot of the second lower side plate 2023b to realize the connection between the second unlocking arm 622 and the second lower side plate 2023b.

[0346] FIG54 is an exploded view of the assembly of the lower housing and the unlocking component in an optical module according to some embodiments of the present disclosure. As shown in FIG54, the first unlocking arm 621b is installed on the outer side of the first lower side plate 2022b, the second unlocking arm 622 is installed on the outer side of the second lower side plate 2023b, the first inclined surface 6211 and the second inclined surface 6212 are embedded in the first recessed area 210, and the third inclined surface 6221 and the fourth inclined surface 6222 are embedded in the third recessed area, so that the first groove formed by the first inclined surface 6211 and the second inclined surface 6212 is recessed in the first lower side plate 2022b, and the second groove formed by the third inclined surface 6221 and the fourth inclined surface 6222 is recessed in the second lower side plate 2023b.

[0347] After the assembly of the optical module 200 is completed, when the optical module 200 is inserted into the cage 106 of the host computer 100, the locking piece on the cage 106 is embedded in the first groove and the second groove on the unlocker 620b, so that the first groove and the second groove on the unlocker 620b are against the locking piece, thereby achieving the locking of the optical module 200 and the host computer 100, and preventing the optical module 200 from being abnormally detached.

[0348] In some embodiments, when the unlocker 620b is installed on the outer side of the side panel of the lower shell 202, the unlocker 620b can be fixedly connected to the side panel. When unlocking the optical module 200 and the host computer 100, the operator grasps the handle 610b and applies force outward, and the unlocker 620b moves outward under the force. At this time, the inclined surface on the unlocker 620b that is inclined from the inside to the outside can lift up the locking plate on the cage 106, so that the unlocker 620b is separated from the locking plate.

[0349] Since the right end of the unlocker 620b is embedded in the recessed area and the locking slot of the lower side plate, the unlocker 620b is fixedly connected to the lower shell 202. When the operator applies outward force, the unlocker 620b drives the lower shell 202 to move outward to pull the optical module 200 out of the upper computer 100, thereby unlocking the optical module 200 and the upper computer 100.

[0350] In some embodiments, when the unlocker 620b is installed on the outer side of the side panel of the lower shell 202, the unlocker 620b can be non-fixedly connected to the side panel, and the unlocker 620b can move forward and backward within a certain range on the side panel. When the unlocker 620b moves forward and backward, the locking plate is lifted up, and then the lower shell 202 is driven to move, thereby pulling the optical module 200 out of the cage 106.

[0351] 51, in order to enable the unlocker 620b to move forward and backward within a certain range on the lower housing 202, a first limit slot 2029 may be formed on the first bearing surface 2030. The first limit slot 2029 is recessed in the first bearing surface 2030, and an opening is formed on the side of the first limit slot 2029 facing away from the lower bottom plate 2021b.

[0352] The first limit slot 2029 is arranged along the length direction of the lower shell 202, and the first limit slot 2029 extends from the first connecting surface 2020 to the outer side of the second side surface 2025b. The limiting length of the first limit slot 2029 is the unlocking stroke size of the unlocker 620b. The first limit slot 2029 is used to limit the movement of the first unlocking arm 621b.

[0353] 53 , a first protrusion 6217 may be disposed on the second inclined surface 6212 . The first protrusion 6217 is located in a direction of the second inclined surface 6212 toward the lower bottom plate 2021 b , and the first protrusion 6217 protrudes from the bottom surface of the second inclined surface 6212 .

[0354] When the first unlocking arm 621b is placed outside the first lower side plate 2022b, the first protrusion 6217 is embedded in the first limit slot 2029. When the optical module 200 is unlocked, the unlocker 620b is forced to move leftward, and the first protrusion 6217 moves leftward along the first limit slot 2029, while the lower housing 202 does not move.

[0355] Similarly, a third limit slot can be formed on the bearing surface of the second lower side plate 2023b. The third limit slot is recessed in the bearing surface of the second lower side plate 2023b, and is used to limit the movement of the second unlocking arm 622.

[0356] 53 , a third protrusion 6227 may be disposed on the fourth inclined surface 6222. The third protrusion 6227 is located in a direction of the fourth inclined surface 6222 toward the lower bottom plate 2021b, and the third protrusion 6227 protrudes from the bottom surface of the fourth inclined surface 6222.

[0357] When the second unlocking arm 622 is placed outside the second lower side plate 2023b, the third protrusion 6227 is embedded in the third limit slot. When the optical module 200 is unlocked, the unlocker 620b is forced to move leftward, and the third protrusion 6227 moves leftward along the third limit slot, while the lower housing 202 does not move.

[0358] In some embodiments, referring to Fig. 51, the first lower side plate 2022b may be provided with a first limiting protrusion 203b, which protrudes outward from the first lower side plate 2022b and is close to the first recessed area 210, so that the unlocker 620b drives the lower housing 202 to move through the first limiting protrusion 203b.

[0359] 53 , a first limiting hole 6215 may be formed on the first arm 6210. The first limiting hole 6215 is located at one end of the first arm 6210 away from the first connecting portion 624 and is arranged along the length direction (left-right direction) of the first arm 6210.

[0360] In some embodiments, the first limiting protrusion 203b is embedded in the first limiting hole 6215 to install the first support arm 6210 on the first lower side plate 2022b, and the first limiting protrusion 203b is used to limit the first unlocking arm 621b from escaping outward, thereby ensuring the connection between the first unlocking arm 621b and the first lower side plate 2022b.

[0361] In some embodiments, the first limiting hole 6215 has a preset length in the length direction, and the preset length may be an unlocking stroke size of the unlocker 620 b so as to limit the movement of the first arm 6210 through the first limiting hole 6215 .

[0362] In some embodiments, a limiting hole may be provided on the first lower side plate 2022 b , and the limiting hole is recessed inwardly in the first lower side plate 2022 b , and the limiting hole is close to the first recessed area 210 .

[0363] A limiting protrusion may be formed on the first support arm 6210 . The limiting protrusion is located on the inner side surface of the first support arm 6210 facing the first lower side plate 2022 b , and the limiting protrusion is protruded toward the inner cavity of the lower housing 202 .

[0364] When the first unlocking arm 621b is installed on the outer side of the first lower side plate 2022b, the limiting protrusion on the first support arm 6210 is embedded in the limiting hole on the first lower side plate 2022b to limit the first unlocking arm 621b from coming out through the limiting protrusion, thereby ensuring the connection between the first unlocking arm 621b and the first lower side plate 2022b.

[0365] In some embodiments, referring to Fig. 51, a second limiting protrusion may be provided on the second lower side plate 2023b. The second limiting protrusion protrudes outward from the second lower side plate 2023b, and the second limiting protrusion is close to the third recessed area.

[0366] 53 , a second limiting hole 6225 may be formed on the second arm 6220 . The second limiting hole 6225 is located at one end of the second arm 6220 away from the second connecting portion 625 , and is disposed along the length direction of the second arm 6220 .

[0367] In some embodiments, the second limiting protrusion is embedded in the second limiting hole 6225 to install the second support arm 6220 on the second lower side plate 2023b, and the second limiting protrusion limits the second unlocking arm 622 from being disengaged, thereby ensuring the connection between the second unlocking arm 622 and the second lower side plate 2023b.

[0368] In some embodiments, the second limiting hole 6225 has a preset length in the length direction, and the preset length may be an unlocking stroke size of the unlocker 620 b so as to limit the movement of the second arm 6220 through the second limiting hole 6225 .

[0369] In some embodiments, a limiting hole may be provided on the second lower side plate 2023b, and the limiting hole is recessed inwardly in the second lower side plate 2023b.

[0370] A limiting protrusion may be formed on the second support arm 6220. The limiting protrusion is located on the inner side surface of the second support arm 6220 facing the second lower side plate 2023b, and the limiting protrusion protrudes toward the inner cavity of the lower housing 202.

[0371] When the second unlocking arm 622 is installed on the outer side of the second lower side plate 2023b, the limiting protrusion on the second support arm 6220 is embedded in the limiting hole on the second lower side plate 2023b to limit the second unlocking arm 622 from coming out through the limiting protrusion, thereby ensuring the connection between the second unlocking arm 622 and the second lower side plate 2023b.

[0372] FIG55 is a partial top view of a lower housing in an optical module according to some embodiments of the present disclosure. As shown in FIG55 , the first limiting protrusion 203b on the first lower side plate 2022b can be a columnar protrusion, and the outer side surface of the first limiting protrusion 203b can be a square surface. The first limiting protrusion 203b is embedded in the first limiting hole 6215, and the first unlocking arm 621b is installed on the outer side of the first lower side plate 2022b through the first limiting protrusion 203b, which can effectively prevent the first unlocking arm 621b from falling out of the lower housing 202.

[0373] The second limiting protrusion on the second lower side plate 2023b can be a columnar protrusion, and the outer side surface of the second limiting protrusion can be a square surface. The second limiting protrusion is embedded in the second limiting hole 6225, and the second unlocking arm 622 is installed on the outer side of the second lower side plate 2023b through the second limiting protrusion, which can effectively prevent the second unlocking arm 622 from falling off the lower shell 202.

[0374] In some embodiments, the thickness dimension of the first limiting protrusion 203b can be equal to the width dimension of the first limiting hole 6215, so that the first limiting protrusion 203b can be embedded in the first limiting hole 6215, so that the first limiting hole 6215 can move left and right along both sides of the first limiting protrusion 203b, and at the same time, the first limiting protrusion 203b can prevent the first unlocking arm 621b from falling out of the first lower side plate 2022b.

[0375] The thickness of the second limiting protrusion can be equal to the width of the second limiting hole 6225, so that the second limiting protrusion can be embedded in the second limiting hole 6225, and the second limiting hole 6225 can move left and right along the two sides of the second limiting protrusion. In this way, the second limiting hole 6225 can move left and right along the two sides of the second limiting protrusion, and the second unlocking arm 622 can be prevented from escaping from the second lower side plate 2023b by the second limiting protrusion.

[0376] In some embodiments, the first limiting protrusion 203b includes a first end and a second end, the first end is far away from the first recessed area 210, the second end is close to the first recessed area 210, the first end has a first thickness dimension H1, the second end has a second thickness dimension H2, and the first thickness dimension H1 is smaller than the second thickness dimension H2.

[0377] Since the thickness of the first end of the first limiting protrusion 203b is smaller than the thickness of the second end, the outer side surface of the first limiting protrusion 203b facing away from the inner cavity of the lower shell 202 has a first outer side surface 2031 and a second outer side surface 2032. The first outer side surface 2031 is inclined from left to right, and the second outer side surface 2032 is a plane.

[0378] When the first limiting protrusion 203b is inserted into the first limiting hole 6215, the first end of the first limiting protrusion 203b is smaller in size, so the first limiting protrusion 203b can be easily inserted into the first limiting hole 6215. The second end of the first limiting protrusion 203b is larger in size, so when the unlocker 620b moves, the second end of the first limiting protrusion 203b can receive the pulling force when the unlocker 620b moves, and transmit the pulling force to the lower housing 202, so as to facilitate the bearing of the force.

[0379] FIG. 56 is an assembly diagram of a lower housing and an unlocking component in an optical module provided according to some embodiments of the present disclosure. As shown in FIG. 56 , when the unlocker 620b is mounted on the side plate of the lower housing 202, the first arm 6210 of the first unlocking arm 621b is placed on the outer side of the first lower side plate 2022b.

The first locking hook 6213 is placed in the first locking groove 2028b.

[0380] Place the second arm 6220 of the second unlocking arm 622 on the outside of the second lower side plate 2023b. Insert the second limiting protrusion into the second limiting hole 6225. Place the third inclined surface 6221 and the fourth inclined surface 6222 in the third recessed area of ​​the second lower side plate 2023b, and place the third protrusion 6227 on the fourth inclined surface 6222 in the third limiting slot of the second lower side plate 2023b. Place the second locking hook 6223 in the second locking slot.

[0381] At this time, the first end of the first limiting protrusion 203b is close to the left end of the first limiting slot 2029, and the right end of the second inclined surface 6212 is against the first connecting surface 2020. The first end of the second limiting protrusion is close to the left end of the third limiting slot, and the right end of the fourth inclined surface 6222 is against the second connecting surface of the second lower side plate 2023b, thereby realizing the connection between the unlocker 620b and the lower housing 202.

[0382] FIG57 is a diagram of the unlocking process of the lower housing and the unlocking component in an optical module provided according to some embodiments of the present disclosure. As shown in FIG57 , when unlocking the optical module 200, the operator grasps the handle 610b and pulls the unlocker 620b to the left, and the first unlocking arm 621b is forced to move to the left. At this time, the lower housing 202 does not move, the first limiting hole 6215 moves to the left along the side of the first limiting protrusion 203b, the first protrusion 6217 on the second inclined surface 6212 moves to the left in the first limiting slot 2029, and the first locking hook 6213 moves to the left in the first locking slot 2028b until the right end of the first limiting hole 6215 abuts against the first limiting protrusion 203b.

[0383] When the right end of the first limiting hole 6215 abuts against the first limiting protrusion 203b, and the first unlocking arm 621b continues to move leftward, the first unlocking arm 621b drives the lower housing 202 to move leftward through the first limiting protrusion 203b, so that the lower housing 202 moves leftward.

[0384] Similarly, when the operator grasps the handle 610b and pulls the unlocker 620b to the left, the second unlocking arm 622 is forced to move to the left, the lower shell 202 remains stationary, the second limiting hole 6225 moves to the left along the side of the second limiting protrusion, the third protrusion 6227 on the fourth inclined surface 6222 moves to the left in the third limiting slot, and the second locking hook 6223 moves to the left in the second locking slot until the right end of the second limiting hole 6225 contacts the second limiting protrusion.

[0385] When the right end of the second limiting hole 6225 abuts against the second limiting protrusion, the second unlocking arm 622 continues to move leftward, and the second unlocking arm 622 drives the lower housing 202 to move leftward through the second limiting protrusion, so that the lower housing 202 moves leftward.

[0386] In some embodiments, the unlocker 620b can be non-fixedly connected to the limiting hole and the shell through the limiting protrusion, so that the unlocker 620b can move left and right on the outside of the shell within a certain range to achieve locking and flexible plugging and unplugging of the optical module 200.

[0387] The unlocker 620b may be non-fixedly connected to the shell through other structures. As long as the unlocker 620b can move left and right on the outside of the shell within a certain range, it belongs to the protection scope of the embodiments of the present disclosure.

[0388] In some embodiments, the unlocker 620b may be installed on the lower side plate of the lower housing 202. When the optical module 200 is unlocked, the unlocker 620b drives the lower housing 202 to move to the left.

[0389] In some embodiments, the unlocker 620b can be installed on the lower side plate of the lower shell 202 and the upper side plate of the upper shell 201. When the optical module 200 is unlocked, the unlocker 620b drives the lower shell 202 and the upper shell 201 to move left to ensure that the optical module 200 is unlocked.

[0390] FIG58 is a structural diagram of an upper housing in an optical module provided according to some embodiments of the present disclosure. As shown in FIG58 , the upper housing 201 may include a first upper side plate 2012b. The first upper side plate 2012b is located on one side of the upper housing 201, and the bottom surface of the first upper side plate 2012b covers the top surface of the first lower side plate 2022b.

[0391] The first upper side plate 2012b may be formed with a second recessed area 211. The second recessed area 211 is recessed in the first upper side plate 2012b, and is located above the first recessed area 210. The first recessed area 210 and the second recessed area 211 form a recessed area on the housing.

[0392] The second recessed area 211 may include a fifth side surface 2014b. One side of the fifth side surface 2014b is connected to the first upper side plate 2012b, and the fifth side surface 2014b is inclined toward the inner cavity of the encapsulated cavity, that is, the fifth side surface 2014b is inclined from outside to inside.

[0395] In some embodiments, a second limiting slot 2016 b may be formed on the second bearing surface 2017 b. The second limiting slot 2016 b is recessed in the second bearing surface 2017 b, and an opening is formed on one side of the second limiting slot 2016 b facing the lower housing 202 .

[0396] 53 , a second protrusion 6216 may be disposed on the second inclined surface 6212 . The second protrusion 6216 is located in a direction from the second inclined surface 6212 toward the upper housing 201 , and the second protrusion 6216 protrudes from the top surface of the second inclined surface 6212 .

[0397] The second protrusion 6216 can be embedded in the second limiting slot 2016b, so that the first unlocking arm 621b moves outside the first upper side plate 2012b through the second protrusion 6216.

[0398] Similarly, the upper housing 201 may include a second upper side plate 2013b. The second upper side plate 2013b is located at the other side of the upper housing 201, and the bottom surface of the second upper side plate 2013b covers the top surface of the second lower side plate 2023b.

[0399] A fourth recessed area may be formed on the second upper side plate 2013b. The fourth recessed area is recessed in the second upper side plate 2013b, and the fourth recessed area is located above the third recessed area on the second lower side plate 2023b. The fourth recessed area and the third recessed area form a recessed area on the housing.

[0400] The fourth recessed area may include a fourth bearing surface. The outer edge of the fourth bearing surface is flush with the outer side surface of the second upper side plate 2013b. A fourth limit slot may be formed on the fourth bearing surface. The fourth limit slot is recessed in the fourth bearing surface, and the fourth limit slot is formed with an opening on one side facing the lower shell 202.

[0401] 53 , a fourth protrusion 6226 may be disposed on the fourth inclined surface 6222 . The fourth protrusion 6226 is located in a direction from the fourth inclined surface 6222 toward the upper housing 201 , and the fourth protrusion 6226 protrudes from the top surface of the fourth inclined surface 6222 .

[0402] The fourth protrusion 6226 can be arbitrarily embedded in the fourth limiting slot, so that the second unlocking arm 622 moves outside the second upper side plate 2013b through the fourth protrusion 6226.

[0403] FIG59 is an assembly structure diagram of an upper housing and an unlocking component in an optical module according to some embodiments of the present disclosure, and FIG60 is an assembly cross-sectional view 1 of an upper housing, a lower housing and an unlocking component in an optical module according to some embodiments of the present disclosure. As shown in FIG59 and FIG60, when the first unlocking arm 621b is placed on the outside of the first upper side plate 2012b, the first inclined surface 6211 and the second inclined surface 6212 are placed in the second recessed area 211, the top surface of the first locking hook 6213 is connected to the bottom surface of the first upper side plate 2012b, and the second protrusion 6216 is embedded in the second limiting slot 2016b, so as to realize the connection between the first unlocking arm 621b and the first upper side plate 2012b.

[0404] When the second unlocking arm 622 is placed on the outside of the second upper side plate 2013b, the third inclined surface and the fourth inclined surface are placed in the fourth recessed area, the top surface of the second locking hook 6223 is connected to the bottom surface of the second upper side plate 2013b, and the fourth protrusion 6226 is embedded in the fourth limiting slot to realize the connection between the second unlocking arm 622 and the second upper side plate 2013b.

[0405] In this way, after the upper shell 201 is covered on the lower shell 202, the unlocking device 620b is placed on the outer side of the upper shell 201 and the lower shell 202, the first unlocking arm 621b is located on the outer side of the first upper side plate 2012b and the first lower side plate 2022b, and the first unlocking arm 621b is non-fixedly connected to the first upper side plate 2012b and the first lower side plate 2022b. The second unlocking arm 622 is located on the outer side of the second upper side plate 2013b and the second lower side plate 2023b, and the second unlocking arm 622 is non-fixedly connected to the second upper side plate 2013b and the second lower side plate 2023b.

[0406] When the optical module 200 is unlocked, when the unlocker 620b is forced to move to the left, the first protrusion 6217 moves to the left along the first limiting slot 2029, the second protrusion 6216 moves to the left along the second limiting slot 2016b, the third protrusion 6227 moves to the left along the third limiting slot, the fourth protrusion 6226 moves to the left along the fourth limiting slot, the first limiting hole 6215 moves to the left along the first limiting protrusion 203b, and the second limiting hole 6225 moves to the left along the second limiting protrusion. At this time, the upper shell 201 and the lower shell 202 do not move.

[0407] When the unlocker 620b continues to move to the left under the force, the right end of the first limiting hole 6215 abuts against the right end of the first limiting protrusion 203b, and the right end of the second limiting hole 6225 abuts against the right end of the second limiting protrusion. At this time, the unlocker 620b transmits the force to the upper shell 201 and the lower shell 202, so that the unlocker 620b drives the upper shell 201 and the lower shell 202 to move to the left.

[0408] In some embodiments, the length dimension of the first limiting slot 2029 and the length dimension of the second limiting slot 2016b can be the same, and the length dimension of the first limiting slot 2029 and the length dimension of the second limiting slot 2016b can be equal to the length dimension of the first limiting hole 6215.

[0409] The length dimension of the first limiting slot 2029 and the length dimension of the second limiting slot 2016 b may be the same, and the length dimension of the first limiting slot 2029 and the length dimension of the second limiting slot 2016 b may be greater than the length dimension of the first limiting hole 6215 .

[0410] FIG61 is a partial assembly diagram of an optical module and a host computer cage according to some embodiments of the present disclosure, and FIG62 is an assembly cross-sectional view of a lower housing, an unlocking component, and a host computer cage in an optical module according to some embodiments of the present disclosure. As shown in FIG61 and FIG62, the upper housing 201 is covered on the lower housing 202, and the unlocking device 620b is installed on the outer side of the upper housing 201 and the lower housing 202 to complete the assembly of the optical module 200. After the assembly of the optical module 200 is completed, the optical module 200 is inserted into the cage 106 of the host computer 100.

[0411] Since one end of the unlocker 620b is tilted inward, the first inclined surface 6211 and the second inclined surface 6212 on the first unlocking arm 621b form a first groove, and the third inclined surface 6221 and the fourth inclined surface 6222 on the second unlocking arm 622 form a second groove. When the optical module 200 is inserted into the cage 106, the locking piece 1061 on the cage 106 is embedded in the first groove and the second groove.

[0412] In some embodiments, when the optical module 200 is pulled in a static environment, since the locking piece 1061 of the cage 106 is inserted into the unlocker 620b, the locking piece 1061 presses against the unlocker 620b, which can prevent the optical module 200 from escaping from the cage 106, thereby achieving locking of the optical module 200 and the cage 106.

[0413] When the optical module 200 needs to be pulled out, the operator grabs the handle 610b and pulls it outward, and the unlocking device 620b is forced to move to the left, and the upper housing 201 and the lower housing 202 do not move. Because the second inclined surface 6212 abuts against the fourth inclined surface 6222 and the locking piece 1061, and the second inclined surface 6212 and the fourth inclined surface 6222 are inclined from the inside to the outside, when the unlocking device 620b moves to the left, the second inclined surface 6212 and the fourth inclined surface 6222 gradually lift the locking piece 1061 when moving to the left, until the locking piece 1061 escapes from the first groove and the second groove on the unlocking device 620b.

[0414] When the locking piece 1061 escapes from the first groove on the unlocker 620b, the right end of the first limiting hole 6215 on the unlocker 620b contacts the first limiting protrusion 203b, and the right end of the second limiting hole 6225 contacts the second limiting protrusion. When the unlocker 620b moves to the left, the external pulling force is transmitted to the upper shell 201 and the lower shell 202. At this time, the upper shell 201, the lower shell 202 and the unlocker 620b move to the left together. Finally, the optical module 200 is unlocked under the action of the external pulling force and escapes from the cage 106.

[0415] After the unlocker 620b moves a certain distance to the left, the unlocker 620b transmits the external pulling force to the shell through the limit protrusion on the shell, so that the unlocker 620b moves to the left together with the shell. However, after the optical module 200 is unlocked, the unlocker 620b is not reset. When the optical module 200 is inserted into the host computer 100 again, the moving stroke of the unlocker 620b is longer.

[0416] FIG63 is a partial structural diagram of a lower housing in an optical module according to some embodiments of the present disclosure, and FIG64 is a structural diagram of a lower housing in an optical module according to some embodiments of the present disclosure. As shown in FIG63 and FIG64, a first spring groove 207 may be formed on the first lower side plate 2022b. The first spring groove 207 is located on a side of the first lower side plate 2022b away from the first locking slot 2028b, and an opening is formed on a side of the first spring groove 207 facing away from the inner cavity.

[0417] A first spring 208 may be installed in the first spring slot 207 . One end of the first spring 208 is fixedly installed on the inner wall of the first spring slot 207 , and the other end of the first spring 208 is movably installed in the first spring slot 207 .

[0418] Similarly, a second spring slot may be formed on the second lower side plate 2023b. The second spring slot is located on a side of the second lower side plate 2023b away from the second locking slot, and an opening is formed on a side of the second spring slot facing away from the inner cavity.

[0419] A second spring may be installed in the second spring slot. One end of the second spring is fixedly installed on the inner wall of the second spring slot, and the other end of the second spring is movably installed in the second spring slot.

[0420] In some embodiments, a first positioning notch 209 may be formed on the first spring slot 207. The first positioning notch 209 is located on a side of the first spring slot 207 facing the upper housing 201, and the first positioning notch 209 is connected to the first spring slot 207.

[0421] 58 , the upper housing 201 may be provided with a first positioning column 2018 . The first positioning column 2018 is located on the inner side of the cover plate 2011 facing the lower housing 202 , is close to the first upper side plate 2012 b , and protrudes from the cover plate 2011 .

[0422] Similarly, a second positioning notch may be formed in the second spring slot. The second positioning notch is located on a side of the second spring slot facing the upper housing 201, and the second positioning notch is connected to the second spring slot.

[0423] A second positioning column may be provided on the upper shell 201. The second positioning column is located on the inner side of the cover plate 2011 facing the lower shell 202, the second positioning column is close to the second upper side plate 2013b, and the second positioning column protrudes from the cover plate 2011.

[0424] When the upper shell 201 is covered on the lower shell 202 , the first positioning post 2018 is inserted into the first positioning notch 209 , and the second positioning post is inserted into the second positioning notch, so as to position and connect the upper shell 201 and the lower shell 202 .

[0425] In some embodiments, when the upper shell 201 and the lower shell 202 are positioned and connected, the positioning posts and positioning notches are not limited to the above-mentioned design methods. As long as the upper shell 201 and the lower shell 202 can be positioned, they all fall within the protection scope of the embodiments of the present disclosure.

[0426] FIG65 is a second structural diagram of an unlocker in an optical module provided according to some embodiments of the present disclosure. As shown in FIG65 , a first spring hook 6214 may be provided on the first unlocking arm 621b. The first spring hook 6214 is located at the connection between the first arm 6210 and the handle 610b, and the first spring hook 6214 protrudes toward the inner cavity of the lower housing 202.

[0427] In some embodiments, the first spring hook 6214 can be formed by stamping, by stamping inward from the outer surface of the first arm 6210, with the right end of the first spring hook 6214 protruding toward the inner cavity of the lower shell 202, and the left end of the first spring hook 6214 fixedly connected to the first arm 6210.

[0428] Similarly, a second spring hook 6224 may be provided on the second unlocking arm 622. The second spring hook 6224 is located at the connection between the second arm 6220 and the handle 610b, and the second spring hook 6224 protrudes toward the inner cavity of the lower housing 202.

[0429] The second spring hook 6224 can be formed by stamping, by stamping inward from the outer surface of the second arm 6210 , with the right end of the second spring hook 6224 protruding toward the inner cavity of the lower shell 202 , and the left end of the second spring hook 6224 fixedly connected to the second arm 6220 .

[0430] FIG66 is a second assembly diagram of a lower housing and an unlocking component in an optical module according to some embodiments of the present disclosure, FIG67 is a second unlocking process diagram of a lower housing and an unlocking component in an optical module according to some embodiments of the present disclosure, and FIG68 is a second assembly cross-sectional diagram of an upper housing, a lower housing, and an unlocking component in an optical module according to some embodiments of the present disclosure. As shown in FIG66, FIG67 and FIG68, when the unlocker 620b is installed on the outer sides of the two lower side plates of the lower housing 202, the first spring hook 6214 extends into the first spring slot 207, and the first spring hook 6214 is connected with the first spring 208. The second spring hook 6224 extends into the second spring slot, and the second spring hook 6224 is connected with the second spring.

[0431] When the optical module 200 is locked with the cage 106, the first spring 208 and the second spring are in a normal state. When the optical module 200 and the cage 106 are unlocked, the unlocker 620b is forced to move to the left, and the first spring hook 6214 compresses the first spring 208 when it moves, and the second spring hook 6224 compresses the second spring when it moves.

[0432] When the unlocker 620b moves to the left, the unlocker 620b gradually lifts the locking plate 1061 on the cage 106 until the limiting hole on the unlocker 620b abuts against the limiting protrusion on the shell. The unlocker 620b transmits the external pulling force to the shell, and the unlocker 620b drives the shell to move to the left. At this time, the first spring 208 and the second spring are no longer compressed.

[0433] After the optical module 200 is pulled out of the cage 106 , since the first spring 208 and the second spring are in a compressed state, when no external pulling force is applied to the unlocking device 620 b , the unlocking device 620 b is reset under the action of the spring force, so that the optical module 200 can be easily inserted into the cage 106 again.

[0434] In some embodiments, when the upper shell 201 is covered on the lower shell 202 and the unlocker 620b is installed on the outside of the upper shell 201 and the lower shell 202, there may be a gap between the right end of the handle 610b and the left end of the lower shell 202, and the left end of the unlocking arm protrudes from the left end of the lower shell 202 so that the handle 610b can be positioned by the unlocker 620b.

[0435] In some embodiments, the first lower side plate 2022b may be formed with a first positioning groove 212. The first positioning groove 212 is recessed in the first lower side plate 2022b, communicates with the first spring groove 207, and extends from the first spring groove 207 to the lower bottom plate 2021b.

[0436] When the unlocker 620 b is installed on the outer side of the lower shell 202 , the handle 610 b can be positioned through the first positioning groove 212 to facilitate the positioning and assembly of the handle 610 b and the lower shell 202 .

[0437] In some embodiments, when the material of the outer wall of the shell and the unlocking component 600 is a relatively hard metal material, direct contact between the hard materials is considered hard contact. In this way, when the outer wall of the shell and the unlocking component 600 are in hard contact, a gap will be generated between the two, so that the electromagnetic waves radiated from the optical port of the optical module can propagate along the gap.

[0438] To prevent electromagnetic waves from being radiated and transmitted along the gap between the outer wall of the housing and the unlocking component 600, referring to Fig. 63, a first shielding portion 206 may be provided on the first lower side plate 2022b. The first shielding portion 206 is located between the first spring groove 207 and the first limiting protrusion 203b, and the first shielding portion 206 extends from the upper portion of the first lower side plate 2022b to the bottom.

[0439] The first unlocking arm 621b covers the first shielding portion 206, and the first lower plate 2022b and the first unlocking arm 621b are conductively connected via the first shielding portion 206. The first shielding portion 206 is used to seal the gap between the first lower plate 2022b and the first unlocking arm 621b.

[0440] Similarly, a second shielding portion may be provided on the second lower side plate 2023b. The second shielding portion is located between the second spring slot and the second limiting protrusion, and the second shielding portion extends from the upper portion to the bottom of the second lower side plate 2023b.

[0441] The second unlocking arm 622 covers the second shielding portion, and the second lower side plate 2023b and the second unlocking arm 622 are conductively connected through the second shielding portion. The second shielding portion is used to seal the gap between the second lower side plate 2023b and the second unlocking arm 622.

[0442] In some embodiments, the first shielding portion 206 and the second shielding portion may be conductive pads, or may be rib protrusions on the lower side plate of the lower housing 202 .

[0443] A conductive pad is arranged between the contact point between the outer wall of the shell and the unlocking component 600. The conductive pad is relatively softer than the outer wall of the shell and the unlocking component 600. The conductive pad can realize conduction between the outer wall of the shell and the unlocking component 600 and can seal the gap between the outer wall of the shell and the unlocking component 600.

[0444] The optical module provided by the embodiment of the present disclosure has a conductive pad disposed on the side panel of the shell, and the side panel and the unlocking component 600 are connected by conductive contact through the conductive pad, thereby avoiding the formation of a gap between the side panel and the unlocking component 600, and further avoiding the radiation and propagation of electromagnetic waves from the gap between the side wall of the shell and the unlocking component, thereby improving the electromagnetic shielding effect of the optical module.

[0445] FIG69 is an exploded view of an unlocking component according to some embodiments. Referring to FIG69 , in some embodiments, the unlocking component 600 includes an unlocking handle 610 (in some examples, it may also be referred to as a gripping portion) and an unlocker 620c, wherein the bottom surface of one end of the unlocker 620c is recessed toward the top surface to form a matching groove 621c, and the other end surface is formed with a snap-fit ​​component 623. When the optical module is in a locked state, that is, when the optical module is connected to the host computer, the unlocking handle 610 is in a static state, and the static state means that the unlocking handle 610 is in a natural drooping state, and the natural drooping state means that the plane where the unlocking handle 610 is located is in a downward state, and at the same time, the unlocker 620c is in a horizontal state, and the engaging component 623 is engaged in the cage of the host computer, thereby locking the optical module in the host computer; when the optical module needs to be unlocked, pull the unlocking handle 610 upwards, and in the process of pulling upwards, the end where the engaging component 623 is located gradually sinks until the engaging component 623 is separated from the cage of the host computer, thereby unlocking the optical module from the host computer.

[0446] FIG70 is a structural diagram of an unlocking handle according to some embodiments; FIG71 is a partial structural diagram of an unlocking handle according to some embodiments. As shown in FIG70 and FIG71, in some embodiments, the unlocking handle 610 includes a body structure 611c, and when the unlocking handle 610 is pulled upward, the unlocking handle 610 can be pulled by pulling the body structure 611c. Exemplarily, the body structure 611c is a U-shaped structure.

[0447] The tail portion of one end of the body structure 611c is respectively formed with a first bending portion 612 and a second bending portion 613 connected to each other. Similarly, the tail portion of the other end of the body structure 611c is respectively formed with a first bending portion 612 and a second bending portion 613 connected to each other. For example, the first bending portion 612 and the second bending portion 613 are both bent structures, such as the first bending portion 612 and the second bending portion 613 are both L-shaped structures. The first bending portion 612 wraps around the limiting portion 2021c to limit the unlocking handle 610 to the lower shell 202.

[0448] The second bending portion 613 at one end is not connected to the second bending portion 613 at the other end, but is disconnected from each other. The first bending portion 612 at one end is connected to the second bending portion 613 end to end, and there is a smooth transition between the two.

[0449] A first groove 615 is formed between the first bending portion 612 and the main body structure 611c, and a second groove 616 is formed between the first bending portion 612 and the second bending portion 613. The first groove 615 and the second groove 616 have different orientations. Exemplarily, the first groove 615 is toward the direction of the lower shell 202, and the first groove 615 wraps the limiting portion 2021c, and the second groove 616 is toward the direction of the upper shell 201.

[0450] A limiting hole 614 is formed on one side of the main body structure 611c near the first bent portion 612, and the limiting hole 614 is embedded in the surface of the limiting column 2022c, and the opening formed between the first bent portion 612 and the main body structure 611c wraps the surface of the limiting portion 2021c, thereby limiting the unlocking handle 610 on the lower housing 202. In some embodiments, when the unlocking handle 610 is pulled upward, the unlocking handle 610 rotates with the limiting column 2022c as a fulcrum, thereby driving the rotation of the unlocker 620c.

[0451] In some embodiments, the second bending portion 613 includes a first connection portion 6131 and a second connection portion 6132 connected in a bending manner. For example, the first connection portion 6131 and the second connection portion 6132 are not connected in a straight line, but are connected in a bending manner, and the first connection portion 6131 is arranged in a warped manner relative to the second connection portion 6132. A connection surface 6136 is formed at the position where the first connection portion 6131 and the second connection portion 6132 are connected.

[0452] In some embodiments, the surface of the first connecting portion 6131 includes a first plane 6133, and the surface of the second connecting portion 6132 includes a second plane 6135. When the unlocking handle 610 is in a stationary state, the first plane 6133 contacts the surface of the mating groove 621c. When the unlocking handle 610 is pulled upward, the second bending portion 613 flips in the mating groove 621c until it flips to the point where the second plane 6135 contacts the surface of the mating groove 621c. During the flipping process, the first plane 6133 gradually flips over from contacting the surface of the matching groove 621c to contacting the surface of the matching groove 621c with the second plane 6135. In order to ensure that the engaging component 623 is completely separated from the upper computer, the height of the end where the matching groove 621c is located should be sufficient. The distance from the second plane 6135 to the opposite side is defined as the first distance, and the first distance is L3 marked in Figure 71. The distance from the first plane 6133 to the connecting surface 6136 between the first connecting part 6131 and the second connecting part 6132 is defined as the second distance, and the second distance is L1 marked in Figure 71. The first distance L3 is greater than the second distance L1, so that the flipping trajectory shows a change in height during the flipping process, and the height of the unlocker 620c also shows a change in height, so that the end where the matching groove 621c is located is lifted, and it is ensured that the height of the end where the matching groove 621c is lifted is sufficient, so that the engaging component 623 sinks to a height sufficient to separate from the cage of the upper computer. Exemplarily, the height of the end where the matching groove 621c is located at the beginning of the flip is lower than the height at the end of the flip, and the height of the end where the locking part 623 is located at the beginning of the flip is higher than the corresponding height at the end of the flip, that is, the end where the matching groove 621c is located is raised, and the end where the locking part 623 is located is sunk until the locking part 623 is completely separated from the upper computer and unlocking is successfully achieved.

[0453] The first distance L3 is greater than the second distance L1, so that the first connection portion 6131 is approximately rectangular. Exemplarily, when the unlocking handle 610 is in a stationary state, the dimension of the first connection portion 6131 along the length direction of the lower shell 202 is greater than its dimension along the width direction of the lower shell 202. The first connection portion 6131 is approximately rectangular, and the flipping trajectory shows a change in height during the flipping process, so that the end where the matching groove 621c is located is lifted, and the end where the engaging component 623 is located sinks.

[0454] In some embodiments, in order to detach the engaging component 623 from the cage of the upper computer, in the process of gradually flipping from the first plane 6133 contacting the surface of the matching groove 621c to the second plane 6135 contacting the surface of the matching groove 621c, when the second plane 6135 contacts the surface of the matching groove 621c, the height of the surface in contact with the matching groove 621c increases compared with when the first plane 6133 contacts the surface of the matching groove 621c. For example, when the second plane 6135 contacts the surface of the matching groove 621c, the center of the limiting column 2022c At this time, when the distance between the second plane 6135 is greater than the distance between the center of the limit column 2022c and the first plane 6133 when the second plane 6135 contacts the surface of the matching groove 621c, the distance between the two states is the height change shown during the flipping process of the second bending portion 613, and the height change is caused by the flipping trajectory of the second bending portion 613. The height change causes the end where the matching groove 621c is located to rise, and the end where the locking component 623 is located to sink, and the sinking height satisfies the locking component 623 to detach from the cage of the upper computer.

[0455] In some embodiments, the surface of the first connection part 6131 includes a first plane 6133 and an arc segment 6134, and the surface of the second connection part 6132 includes a second plane 6135. The first plane 6133 and the second plane 6135 are connected by the arc segment 6134. When the optical module is in a locked state, the first plane 6133 is located on the top surface of the first connection part 6131, the arc segment 6134 is located on the side of the first connection part 6131, and the second plane 6135 is located on the side of the second connection part 6132. When the unlocking handle 610 is pulled upward, the second bending part 613 is flipped in the matching groove 621c. During the flipping process, the arc segment 6134 and the surface of the matching groove 621c maintain tangent motion. When the two are tangent, the flipping friction of the second bending part 613 can be reduced, thereby increasing the smoothness of unlocking.

[0456] The first plane 6133, the arc segment 6134, and the second plane 6135 are connected to form a contact surface. As the unlocking handle 610 rotates, different parts of the contact surface will contact the unlocking device 620c. Similarly, the engaging component 623 is ensured to be completely separated from the upper computer. The distance between the second plane 6135 and the side opposite to it is the first distance, which is L3 marked in FIG. 71. The distance between the first plane 6133 and the connecting surface between the first connecting portion 6131 and the second connecting portion 6132 is the second distance, which is L3 marked in FIG. 71. Marked L1, the first distance is greater than the second distance, so that the flipping trajectory shows a change in height during the flipping process, and the height of the unlocker 620c also shows a change in height. For example, the height of the end where the matching groove 621c is located at the beginning of the flip is lower than the height at the end of the flip, and the height of the end where the locking component 623 is located at the beginning of the flip is higher than the corresponding height at the end of the flip, that is, the end where the matching groove 621c is located is lifted, and the end where the locking component 623 is located is sunk, until the locking component 623 is completely separated from the upper computer, and the unlocking is successfully achieved.

[0457] The first distance L3 is greater than the second distance L1, and the distance between the arc segment 6134 and the opposite side is the third distance L2, and the size of the third distance L2 is between the first distance L3 and the second distance L1, so that the first connection portion 6131 presents an approximately rectangular shape. Exemplarily, when the unlocking handle 610 is in a stationary state, the size of the first connection portion 6131 along the length direction of the lower shell 202 is greater than its size along the width direction of the lower shell 202. When the first connection portion 6131 is in an approximately rectangular shape, during the rotation of the unlocking handle 610, the size in the unlocking path changes, and the height in the later stage of unlocking is greater than the height in the early stage of unlocking, thereby lifting the end where the matching groove 621c is located, and sinking the end where the engaging component 623 is located, thereby achieving unlocking.

[0458] FIG. 72 is a structural diagram of an unlocker according to some embodiments; FIG. 73 is a structural diagram of an unlocker according to some embodiments. As shown in FIG. 72 and FIG. 73, in some embodiments, the bottom surface of one end of the unlocker 620c close to the optical port is recessed toward the top surface to form a matching groove 621c, and the matching groove 621c covers the surface of the second bending portion 613 at both ends, and the end of the second bending portion 613 extends into the matching groove 621c; a clamping part 623 is formed at the other end of the unlocker 620c; a through hole 622 is formed on the middle structure of the unlocker 620c, and the through hole 622 passes through the connecting shaft 2024c and can rotate around the connecting shaft 2024c. When the unlocking handle 610 is pulled upward, the unlocker 620c is driven to rotate around the connecting shaft 2024c, so that the end where the clamping part 623 is located sinks until the clamping part 623 is pulled out of the cage of the host computer, thereby realizing the unlocking of the optical module. At this time, the connecting shaft 2024c is located on the lower housing 202, and the connecting shaft 2024c serves as a rotation axis, and the lower housing 202 provides a rotation axis for the rotation of the unlocking device 620c. For example, the rotation axis can be arranged in the unlocking device 620c, and correspondingly, through holes are formed on both sides of the lower housing 202 to embed the rotation axis, that is, the unlocking device 620c itself is formed with a rotation axis.

[0459] A protrusion 624 is formed on the side of the unlocker 620c opposite to the engaging part 623, and a spring 2025c is provided on one side of the connecting shaft 2024c in the lower shell 202, and the protrusion 624 is connected to the spring 2025c, so that the unlocker 620c and the spring 2025c are connected together. When the optical module needs to be unlocked, the end where the engaging part 623 is located presses the spring 2025c to sink, and when the unlocking is completed, the unlocker 620c is reset under the rebound effect of the spring 2025c, and at the same time, the spring 2025c can also play a certain buffering role in the sinking process.

[0460] FIG74 is a cross-sectional view of an unlocking component according to some embodiments. As shown in FIG74 , in some embodiments, the second bending portions 613 on both sides extend from the bottom end into both sides of the matching groove 621c, and the unlocker 620c is covered on the surface of the second bending portions 613 on both sides. For example, one side of the matching groove 621c is covered on the surface of the second bending portion 613 on one side, and the other side is covered on the surface of the second bending portion 613 on the other side.

[0461] When the unlocking handle 610 is pulled upward, the second bending parts 613 on both sides rotate and flip in the matching groove 621c, so that the end of the unlocking device 620c where the matching groove 621c is located is lifted, and the end where the engaging part 623 is located is sunk, thereby realizing the unlocking of the optical module. Since the second bending parts 613 on both sides need to rotate and flip in the matching groove 621c, there are certain preset requirements for the size of the matching groove 621c. For example, the size of the matching groove 621c along the width direction of the lower shell 202 is greater than the distance between the second bending parts 613 on both sides, and the size of the matching groove 621c along the length direction of the lower shell 202 is greater than the length of the second bending part 613, thereby providing sufficient space for the second bending part 613 to rotate and flip in the matching groove 621c.

[0462] FIG75 is a cross-sectional view of an optical module according to some embodiments; FIG76 is a cross-sectional exploded view of an optical module according to some embodiments. As shown in FIG75 and FIG76, in some embodiments, the limiting hole 614 of the unlocking handle 610 is embedded in the surface of the limiting column 2022c, and then the first bending portion 612 wraps the limiting portion 2021c downwardly, thereby limiting the unlocking handle 610 on the lower shell 202; the second bending portion 613 supports the unlocking device 620c upward, so that when the unlocking handle 610 is pulled, the second bending portion 613 is turned to drive the rotation of the unlocking device 620c, thereby lifting the end of the unlocking device 620c where the matching groove 621c is located, and sinking the end where the engaging component 623 is located, thereby realizing the unlocking of the optical module. Exemplarily, when the unlocking handle 610 is pulled, the unlocking handle 610 rotates with the limiting column 2022c as the fulcrum. In order to prevent the unlocking handle 610 from slipping out of the limiting column 2022c during the rotation, the distance between the outer walls of the limiting columns 2022c on both sides is greater than the distance between the outer walls of the main body structure 611c on both sides, so that the outer wall of the limiting column 2022c protrudes relative to the outer wall of the main body structure 611c, thereby preventing the surface unlocking handle 610 from slipping out of the limiting column 2022c.

[0463] As shown in Figures 75 and 76, when the optical module is in a locked state, the unlocking handle 610 is in a naturally drooping state. At this time, the unlocker 620c covers the surface of the first plane 6133 on both sides. For example, the matching groove 621c covers the surface of the first plane 6133 on both sides, and the surface of the matching groove 621c is in contact with the first plane 6133.

[0464] In some embodiments, the unlocking handle 610 in Figures 75 and 76 is pulled upward. During the pulling process, the arc segment 6134 and the surface of the mating groove 621c remain tangent to each other. The second bending portion 613 is rotated with the tangent point formed by the tangency as a fulcrum. During the rotation process, it is gradually flipped from the first plane 6133 contacting the surface of the mating groove 621c to the second plane 6135 contacting the surface of the mating groove 621c. The flipping trajectory lifts the end of the unlocker 620c where the mating groove 621c is located, and sinks the end where the locking part 623 is located, thereby unlocking the optical module.

[0465] In the unlocking process of the present disclosure, when the unlocking handle 610 is pulled upward, the second bent portion 613 is driven to flip the contact surface in the matching groove 621c, and the end where the engaging component 623 is located is sunk by the height difference generated by the flipping, thereby unlocking the optical module. In the process of the second bent portion 613 flipping to achieve unlocking, the arc segment 6134 and the surface of the matching groove 621c remain tangent, thereby reducing the friction during the flipping process, making the force more coherent, thereby further increasing the smoothness of unlocking and improving the unlocking experience.

[0466] FIG77 is a schematic diagram of the unlocking principle of an unlocking component according to some embodiments; FIG78 is a cross-sectional diagram of the unlocking principle of an unlocking component according to some embodiments. As shown in FIG77 and FIG78, the left and right sides of the arrows respectively correspond to the states when the optical module is in a locked state and the optical module is in an unlocked state. The unlocking handle 610 is pulled upward from the position where the unlocking handle 610 is located on the left side of the arrow, and gradually changes to the state on the right side of the arrow during the pulling process. It can be seen from the state on the right side of the arrow that at this time, the end of the unlocker 620c where the matching groove 621c is located is lifted, and the end where the engaging component 623 is located is sunk, so that the optical module can be unlocked.

[0467] The optical module on the left side of the arrow is in a locked state. At this time, the first plane 6133 of the second bent portion 613 is in contact with the surface of the matching groove 621c, and the unlocker 620c is in a horizontal state. When the optical module needs to be unlocked, the unlocking handle 610 is pulled upward. During the pulling process, the second bent portion 613 is flipped in the matching groove 621c. For example, the arc segment 6134 is tangent to the surface of the matching groove 621c, and the second bent portion 613 is rotated with the tangent point formed by the tangency as the fulcrum, and the unlocker 620c is turned. 0c is in an inclined state, and gradually changes from the first plane 6133 contacting the surface of the matching groove 621c to the arc segment 6134 contacting the surface of the matching groove 621c, and then continues to rotate and flip until it changes to the second plane 6135 contacting the surface of the matching groove 621c. During these changes, one end where the matching groove 621c is located is gradually lifted, and one end where the engaging part 623 is located is gradually sunk, and the sinking height satisfies the engagement part 623 to be separated from the cage of the host computer, thereby realizing the unlocking of the optical module. It can be seen that in the process of the second bending part 613 flipping to realize unlocking, the arc segment 6134 and the surface of the matching groove 621c remain tangent, thereby reducing the friction during the flipping process, making the force more coherent, thereby increasing the smoothness of unlocking and improving the unlocking experience.

[0468] FIG79 is a structural diagram of an optical module in a locked state according to some embodiments. As shown in FIG79 , in some embodiments, when the optical module is in a locked state, the unlocker 620c is covered on the surface of the first plane 6133, and is pulled upward along the current position of the unlocking handle 610, and the arc segment 6134 is kept tangent to the surface of the matching groove 621c, and is rotated and flipped with the tangent point as the fulcrum until the second plane 6135 contacts the surface of the matching groove 621c. The height change amount shown in this change process is generated by the flipping trajectory of the second bending portion 613, and the height change amount causes the end where the matching groove 621c is located to rise, and the end where the engaging component 623 is located to sink, and the sinking height satisfies the engagement component 623 to be separated from the cage of the host computer.

[0469] FIG80 is a structural diagram of an optical module in an unlocked state according to some embodiments. As shown in FIG81 , in some embodiments, when the optical module is in an unlocked state, the second plane 6135 contacts the surface of the matching slot 621c. If the distance between the first plane 6133 and the side opposite to the first plane 6133 is smaller than the distance between the second plane 6135 and the side opposite to the second plane 6135, then in the process of gradually flipping from the first plane 6133 contacting the surface of the matching slot 621c to the second plane 6135 contacting the surface of the matching slot 621c, the change in height makes the engaging part 623 sink to a sufficient height to detach from the cage of the host computer, thus successfully achieving unlocking.

[0470] [Corrected 14.09.2024 according to Rule 91] Figure 81 is a diagram of an unlocking process of an unlocking component according to some embodiments. As shown in Figure 81, in some embodiments, when the optical module is in a locked state, the unlocker 620c is covered on the surface of the first plane 6133, the surface of the matching groove 621c is in contact with the first plane 6133, and the unlocker 620c is in a horizontal state.

[0471] FIG82 is a second diagram of an unlocking process of an unlocking component according to some embodiments. As shown in FIG82, in some embodiments, when the unlocking handle 610 is gradually pulled upward along the current position of the unlocking handle 610 in FIG81, the unlocking device 620c is driven to rotate along the connecting shaft 2024c, and the unlocking device 620c begins to present an inclined state, illustratively, gradually changing from the first plane 6133 contacting the surface of the matching groove 621c to the arc segment 6134 contacting the surface of the matching groove 621c, and the state at this time still cannot make the engaging component 623 detach from the cage of the host computer.

[0472] FIG83 is a third diagram of an unlocking process of an unlocking component according to some embodiments. As shown in FIG83 , in some embodiments, when the unlocking handle 610 is gradually pulled upward along the current position of the unlocking handle 610 in FIG82 , the unlocking device 620c is continuously driven to rotate along the connecting shaft 2024c. In this process, the arc segment 6134 remains tangent to the surface of the matching groove 621c, and continues to rotate and flip at the tangent point until the second plane 6135 contacts the surface of the matching groove 621c. The height variation shown in the rotation and flipping process is generated by the flipping trajectory of the second bending portion 613. The height variation causes the end where the matching groove 621c is located to rise, and the end where the engaging component 623 is located to sink, and the sinking height satisfies the engagement component 623 to be separated from the cage of the upper computer.

[0473] According to the unlocking component in the present disclosure, when the unlocking handle is in a naturally drooping state, the plane where the unlocker is located is parallel to the surface of the upper shell body, and the first plane is in contact with the surface of the matching groove. At this time, the unlocker is engaged in the cage of the upper computer, thereby realizing the connection relationship between the optical module and the upper computer; when the unlocking handle is pulled upward, the second bent portion of the unlocking handle flips in the matching groove until the second plane is in contact with the surface of the matching groove. Since the distance between the second plane and the side opposite to the second plane is greater than the distance between the second plane and the connecting surface, there is a height change in the flipping trajectory during the flipping process. Exemplarily, the height of the matching groove at the end of the flipping is higher than the height of the matching groove at the beginning of the flipping. The flipping trajectory of the second bent portion causes the end of the unlocker where the matching groove is located to rise, and the end where the engaging component is located to sink, until the engaging component is detached from the cage of the upper computer, thereby releasing the connection relationship between the optical module and the upper computer, thereby realizing the unlocking of the optical module. In the present disclosure, a second bend is formed at the end of the unlocking handle. By flipping the second bend in the matching groove, since the distance between the second plane and the side opposite to the second plane is greater than the distance between the second plane and the connecting surface, the second bend is approximately rectangular at this time, and the flipping trajectory shows a change in height, thereby causing the end where the engaging component is located to sink until it is separated from the cage of the host computer, thereby successfully achieving unlocking. In the present disclosure, by flipping the second bend that is approximately rectangular, the trajectory shows a change in height, thereby achieving unlocking. At the same time, the trajectory is smooth during the unlocking process, thereby improving the smoothness of unlocking the optical module and improving the unlocking experience.

[0474] FIG84 is a structural diagram of an optical network terminal cage according to some embodiments. As shown in FIG84, in some embodiments, the cage of the host computer, such as the port of the cage 106 of the optical network terminal 100, has a spring 1061 that matches the engaging component of the unlocking component 400, and the spring 1061 includes a fixed end and a free end, the fixed end is used to be fixed on the cage 106, and the free end can move up and down, and the surface of the free end is provided with a card interface 1062, and the card interface 1062 matches the engaging component 318. When the engaging component 318 is engaged in the card interface 1062, the electrical port module 300 (in some examples, it can also be called an optical module) is fixed in the host computer, thereby realizing the locking of the electrical port module 300; when the engaging component 318 is disengaged from the card interface 1062, the electrical port module 300 is separated from the host computer, thereby realizing the unlocking of the electrical port module 300.

[0475] In some embodiments, when the spring piece 1061 remains relatively still, its free end is tilted relative to the fixed end, and the surface of the spring piece 1061 is an inclined surface. The inclined spring piece 1061 is more conducive to unlocking the electrical port module 300 than the planar spring piece.

[0476] When unlocking the electrical port module 300, there are many ways to release the engagement relationship between the electrical port module 300 and the host computer. In some embodiments, the host computer cage is kept relatively fixed, and the locking component 318 is sunk, so that the electrical port module 300 actively escapes from the spring 1061, and the electrical port module 300 is separated from the host computer; in some embodiments, the locking component 318 is kept relatively fixed, and the spring 1061 is pushed up, so that the electrical port module 300 is passively escaped from the spring 1061, and the electrical port module 300 is separated from the host computer. In the present disclosure, since the locking component 318 is provided on the surface of the upper shell 310, and is not provided on the surface of the unlocker 420, in some embodiments, the locking component 318 can be kept relatively fixed, and the spring 1061 is pushed up to achieve the unlocking of the electrical port module 300.

[0477] In some embodiments, when the unlocking handle 410 remains in a natural drooping state, the unlocker 420 remains relatively still, and there is a certain distance between the unlocker 420 and the engaging part 318. Then, the unlocker 420 cannot act on the engaging part 318 and the spring piece 1061, and cannot separate the two, thereby keeping the electrical port module 300 in a locked state.

[0478] In some embodiments, when the electrical port module 300 is unlocked, when the unlocking handle 410 is pulled upward in the direction of the upper shell 310, the unlocker 420 can slide along the upper shell 310 toward the locking component 318 and the spring piece 1061 under the action of the thrust, and the sliding unlocker 420 gradually approaches the locking component 318 and the spring piece 1061, and then gradually lifts the spring piece 1061 until the spring piece 1061 is disengaged from the locking component 318, thereby achieving the unlocking of the electrical port module 300.

[0479] FIG85 is a structural diagram of an unlocking component according to some embodiments. As shown in FIG85 , in some embodiments, the unlocking component 400 includes an unlocking handle 410 and an unlocker 420 connected to each other, the unlocking handle 410 is rotatably connected relative to the upper shell 310, and the unlocker 420 is slidably connected relative to the upper shell 310. When the unlocking handle 410 is pulled upward along the side wall of the upper shell 310, the unlocking handle 410 rotates relative to the upper shell 310, and during the rotation of the unlocking handle 410, the unlocker 420 is driven to move along the first guide rail 313 and the second guide rail 314 toward the engaging component 318 and the spring 1061, and the gradually moving unlocker 420 slowly acts on the spring 1061, slowly lifting the spring 1061 until the spring 1061 is separated from the engaging component 318, and the engaging component 318 is passively separated from the spring 1061, thereby realizing the unlocking of the electrical port module 300.

[0480] In some embodiments, in order to limit the unlocking handle 410 to the side wall of the upper shell 310, a first nesting hole 414 and a second nesting hole 415 are respectively formed on both sides of the surface of the unlocking handle 410. The first nesting hole 414 is nested on the first rotating axis 315, and the second nesting hole 415 is nested on the second rotating axis 316, thereby limiting the unlocking handle 410 to the side wall of the upper shell 310, and can rotate along the first rotating axis 315 and the second rotating axis 316.

[0481] In some embodiments, the unlocker 420 includes a body structure 421, which is disposed between the first plate 311 and the second plate 312. In order to realize that when the unlocking handle 410 is rotated, the unlocking handle 410 is pushed toward the engaging part 318 and the spring 1061, a boss 411 is formed on the surface of the unlocking handle 410, and the boss 411 is disposed between the first nesting hole 414 and the second nesting hole 415. When the unlocking handle 410 is rotated, the boss 411 rotates accordingly, and during the rotation of the boss 411, a thrust is applied to the end surface of the body structure 421, thereby pushing the unlocking handle 420 to move, so that the unlocking handle 420 gradually approaches the engaging part 318 and the spring 1061, thereby acting on the spring 1061 to lift the spring 1061, thereby realizing the unlocking of the electrical port module 300. For example, in order to increase the smoothness of the force applied when the boss 411 rotates to push the unlocker 420 to move, the surface of the boss 411 in contact with the unlocker 420 is a smooth curved surface, thereby reducing the friction between the two and increasing smoothness.

[0482] In some embodiments of the present disclosure, when the boss 411 cooperates with the main body structure 421, whether the surfaces of the boss 411 and the main body structure 421 are flush affects the fit. Due to processing errors and assembly errors, there is a certain height difference between the boss 411 and the surface of the unlocker 420, which affects the interaction between the two. When the contact area between the boss 411 and the unlocker 420 is large, this effect is particularly obvious. At the same time, when the contact area between the boss 411 and the main body structure 421 is large, the force is more dispersed, which is not conducive to generating an effective unlocking stroke. Therefore, in some embodiments, the end of the main body structure 421 extends the first arm 422 toward the unlocking handle 410. In order to cooperate with the first arm 422, a surface of the boss 411 is recessed to form a notch 412. The notch 412 rotates with the rotation of the unlocking handle 410. As the notch 412 rotates, the notch 412 squeezes the first arm 422. Under the squeezing, the first arm 422 slides along the inside of the notch 412. When the first arm 422 slips out of the notch 412, it continues to be abutted by the side wall 418 connected to the notch 412, so that the first arm 422 moves toward the engaging component 318, thereby pushing the unlocker 420 to move toward the position where the spring piece 1061 is located, generating a certain unlocking stroke. The contact area between the first arm 422 and the notch 412 is relatively smaller than the contact area between the boss 411 and the main structure 421, thereby reducing the influence of the uneven surfaces of the boss 411 and the main structure 421 on the interaction. At the same time, the force is concentrated on the action surface between the first arm 422 and the notch 412, so that the force is more concentrated, which is conducive to generating an effective unlocking stroke. At the same time, due to the setting of the notch 412, when the electrical port module 300 is in a locked state, the unlocker 420 is closer to the unlocking handle 410, and is further away from the engaging component 318 and the spring 1061, so it will not act on the spring 1061, and will not destroy the engaging relationship between the spring 1061 and the engaging component 318, so that the electrical port module 300 remains in a locked state.

[0483] When the notch 412 is L-shaped, it has better openness, so that at the moment when the notch 412 and the first arm 422 are separated, the unlocker 420 can be separated from the notch 412 and is no longer restricted by the notch 412.

[0484] In some embodiments, in order to keep a certain distance between the unlocker 420 and the spring 1061 when the electrical port module 300 is in a locked state, otherwise the electrical port module 300 will be unlocked, destroying the current locked state. Exemplarily, when the electrical port module 300 is in a locked state, a longer distance is kept between the unlocker 420 and the spring 1061. In order to ensure that a longer distance is kept between the unlocker 420 and the spring 1061 when the electrical port module 300 is in a locked state, the first arm 422 is shorter in length to shorten the relative length of the unlocker 420 when the electrical port module is in a locked state, thereby lengthening the distance from the spring 1061, thereby avoiding acting on the spring 1061 and maintaining the locked state of the electrical port module. Correspondingly, the notch 412 is located on the side of the boss 411 facing the engaging component 318, and the notch 412 is relatively closer to the engaging component 318.

[0485] In some embodiments, when unlocking the electrical port module 300, sufficient unlocking stroke should be provided so that the unlocker 420 can completely lift the spring sheet 1061, thereby completely separating the spring sheet 1061 from the engaging component 318, and successfully unlocking. When the first arm 422 is a short arm with a shorter length, when the unlocking handle 410 is pulled to a certain height, the notch 412 and the first arm 422 will be staggered with each other, no longer in contact and connection, and the first arm 422 will no longer be squeezed, and the unlocking stroke will not continue to be generated at this time. For example, at a certain moment, the first arm 422 will be separated from the notch 412, and the two will be disconnected, so that the notch 412 will no longer continue to push the first arm 422 to generate the unlocking stroke.

[0486] In some embodiments, in order to generate a continuous and sufficient unlocking stroke, in the boss 411, a surface opposite to the surface where the notch 412 is located is recessed to form a groove 413. For example, one surface of the boss 411 is recessed toward the inner direction of the boss 411 to form the notch 412, and the other surface of the boss 411 is also recessed toward the inner direction of the boss 411 to form the groove 413. The groove 413 and the notch 412 are located at the diagonal position of the boss 411, and the groove 413 is farther away from the engaging part 318 than the notch 412. The recessed directions of the groove 413 and the notch 412 are oppositely arranged, and the opening directions of the groove 413 and the notch 412 are different. For example, the opening of the notch 412 is toward the side where the engaging part 318 is located, and the opening of the groove 413 is away from the side where the engaging part 318 is located. Matching the groove 413, the end surface of the main body structure 421 facing the unlocking handle 410 also extends a second arm 423. In order to facilitate the extension, the second arm 423 extends from the side wall of the main body structure 421, and the second arm 423 is arranged on the side of the main body structure 421. Since the groove 413 is farther away from the engaging part 318 than the notch 412, that is, the groove 413 is farther away from the main body structure 412 than the notch 412, the second arm 423 extends from the side wall of the main body structure 421, and the end of the second arm 423 is bent to form a bent portion 424. The length of the second arm 423 is relatively long, and illustratively, it has a preset length, so that the bent portion 424 passes over the side of the boss 411 until it extends to the position where the groove 413 is located, thereby extending the bent portion 424 to the groove 413. Exemplarily, the second arm 423 is connected to the bent portion 424 by bending, and the end of the second arm 423 is bent inward to form the bent portion 424 .

[0487] The groove 413 is farther away from the locking part 318 relative to the notch 412, and correspondingly, the bent portion 424 is farther away from the locking part 318 relative to the first arm 422. The second arm 423 extends the bent portion 424 at the end to the position of the groove 413, so that the groove 413 interacts with the bent portion 424, and the notch 412 interacts with the first arm 422. Since the notch 412 is closer to the groove 413, the length of the first arm 422 is relatively shorter than the length of the second arm 423.

[0488] As the unlocking handle 410 rotates, the notch 412 rotates accordingly, and the rotating notch 412 squeezes the first arm 422, thereby pushing the first arm 422 to move. Since the length of the first arm 422 is relatively short, for example, the length of the first arm 422 is less than the length of the second arm 423, the first arm 422 and the notch 412 will be disconnected due to mutual displacement during the rotation of the notch 412, and the first arm 422 and the side wall 418 will also be disconnected due to mutual displacement. At this time, the first arm 422 is no longer subjected to force, and the unlocking device 420 cannot be moved further. In order to completely lift up the spring sheet 1061 and completely disengage the spring sheet 1061 from the engaging component 318, the present invention During opening, through the cooperation between the groove 413 and the bent portion 424, as the first arm 422 moves, the bent portion 424 enters the groove 413, and the groove 413 rotates as the unlocking handle rotates. At this time, the inner wall of the groove 413 squeezes the bent portion 424, so that the second arm 423 moves toward the engaging part 318. Even if the notch 412 no longer continues to act on the first arm 422 to produce an unlocking stroke, the unlocking process can still continue until the spring piece 1061 is completely lifted up and the electrical port module is detached from the upper computer.

[0489] In the present disclosure, the first arm 422 is squeezed by the notch 412 at the beginning of the rotation of the unlocking handle 410, driving the main body structure 421 to move. In the process of the movement of the first arm 422, the bending portion 424 enters the groove 413. At this time, the bending portion 424 is squeezed by the groove 413, driving the second arm 423 to move, and the movement of the second arm 423 drives the main body structure 421 to move. In the present disclosure, the unlocking stroke is continuously generated by the forces at the first arm 422 and the bending portion 424, thereby increasing the unlocking stroke and achieving complete unlocking. The first arm 422 is short in length, and then the second arm 423 extends from the side over the boss 411. This design can make the first arm 422 and the second arm 423 more concentrated, which is conducive to miniaturization. At the same time, when in the locked state, it deviates far from the engaging component 318 and maintains a certain distance from the engaging component 318, thereby avoiding acting on the spring sheet and destroying the locked state. Assuming that unlocking is performed only through the first arm 422, the length of the first arm 422 is relatively long, which is not conducive to miniaturization of the size, and it is impossible to maintain a long distance from the engaging part 318. Assuming that unlocking is performed only through the second arm 423, the second arm 423 will be subjected to force at the beginning of the rotation of the unlocking handle 410, which is not conducive to generating a long unlocking stroke. The present disclosure generates a progressive unlocking stroke by progressively applying force to the shorter first arm 422 and the second arm 423 extending from the side, providing a continuous and sufficient unlocking stroke. The present disclosure is cleverly designed, which is conducive to miniaturization of the size; and it generates a longer unlocking stroke, thereby achieving complete unlocking. In some embodiments, the progressive unlocking can be that the bending portion 424 is subjected to force at the moment when the first arm 422 stops being subjected to force; in some embodiments, the progressive unlocking can also be that the bending portion 424 has started to be subjected to force before the first arm 422 stops being subjected to force.

[0490] The shape of the groove 413 can be U-shaped, with good wrapping properties to prevent the bending portion 424 from slipping out of the groove 413, increase the moving time of the bending portion 424 in the groove 413, thereby generating a longer unlocking stroke and achieving complete unlocking of the electrical port module 300.

[0491] When the electrical port module 300 is in a locked state, the bent portion 424 does not contact the groove 413 to maintain the locked state of the electrical port module 300. When the unlocking handle 410 is rotated to a certain height, the bent portion 424 begins to contact the groove 413. As the unlocking handle 410 rotates, the compression between the groove 413 and the bent portion 424 pushes the unlocker 420 toward the engaging component 318 and the spring 1061, thereby increasing the unlocking stroke and providing a continuous and sufficient unlocking stroke until the spring 1061 is completely lifted up and the electrical port module is separated from the upper computer.

[0492] FIG86 is a structural diagram 1 of an unlocking handle according to some embodiments; FIG87 is a structural diagram 2 of an unlocking handle according to some embodiments. As shown in FIG86 and FIG87, in some embodiments, the unlocking handle 410 includes a fixed end and a free end, the fixed end is fixed to the upper shell 310, and the fixed end is the end of the unlocking handle 410 connected to the upper shell 310, and a notch 412 and a groove 413 are formed on both sides of the end, respectively. The free end of the unlocking handle 410 is freely arranged relative to the upper shell 310, and when the free end is pulled upward, the unlocking handle 410 rotates along the side wall of the upper shell 310. The boss 411 is at the fixed end of the unlocking handle 410. The notch 412 and the groove 413 are respectively arranged on two different surfaces of the boss 411, and illustratively, the notch 412 is farther away from the engaging part than the groove 413.

[0493] In order to limit the unlocking handle 410 on the side wall of the upper shell 310, a first nesting hole 414 and a second nesting hole 415 are respectively formed on both sides of the surface of the fixed end of the unlocking handle 410, the first nesting hole 414 is nested on the first rotating shaft 315, and the second nesting hole 415 is nested on the second rotating shaft 316, so that the unlocking handle 410 is limited on the side wall of the upper shell 310, and the unlocking handle 410 can rotate along the first rotating shaft 315 and the second rotating shaft 316. In order to avoid some structures, a first avoidance portion 416 is formed on one side of the second nesting hole 415, and a second avoidance portion 417 is formed on one side of the first nesting hole 414.

[0494] In some embodiments, in order to increase the smoothness of unlocking, the notch 412 includes a first accommodating cavity 4121 and a first rounded corner 4122. The first accommodating cavity 4121 is used to accommodate the first support arm 422. The first rounded corner 4122 is located at the top of the first accommodating cavity 4121. As the unlocking handle 410 rotates, the opening of the notch 412 rotates downward. During the rotation, the first rounded corner 4122 contacts the first support arm 422, and the inner wall of the notch 412 squeezes the first support arm 422. During the pulling process, the first rounded corner 4122 acts tangentially to the first support arm 422, and the tangent point of the two is used as a fulcrum, thereby pushing the unlocker 420 forward. "Pushing the unlocker 420 forward" refers to pushing the unlocker 420 in the direction of the locking component 318 and the spring piece 1061. When the first fillet 4122 is separated from the first arm 422, the side wall 418 connected to the notch 412 will abut against the first arm 422 until the side wall 418 is separated from the first arm, and the first arm 422 will no longer be subjected to force, and thus cannot drive the main structure to move. Due to the smooth surface of the first fillet 4122, the tangential motion friction between the first fillet 4122 and the first arm 422 makes the motion smoother, thereby making the unlocking process smoother.

[0495] In some embodiments, in order to increase the smoothness of unlocking, the groove 413 includes a second accommodating cavity 4131, a second rounded corner 4132 and a curved surface 4133. As the unlocking handle 410 rotates, the opening of the groove 413 rotates upward, and the curved surface 4133 begins to contact the bent portion 424. The curved surface 4133 squeezes the bent portion 424, thereby pushing the bent portion 424 to move toward the second rounded corner 4132. As the unlocking handle 410 continues to rotate, the bent portion 424 contacts the second rounded corner 4132, and the two also move tangentially. , with the tangent point of the two as the fulcrum, the bent portion 424 is moved toward the second accommodating cavity 4131, and the second accommodating cavity 4131 squeezes the bent portion 424, so that the bent portion 424 pushes the unlocker 420 toward the locking component 318 and the spring sheet 1061, until the unlocker 420 completely lifts the spring sheet 1061 and completely separates the spring sheet 1061 from the locking component 318, thereby releasing the locking relationship between the electrical port module 300 and the host computer, separating the electrical port module 300 from the host computer, and unlocking the electrical port module 300.

[0496] In some embodiments, in order to ensure that the unlocking stroke occurs when the notch 412 squeezes the first arm 422, the inner wall size of the notch 412 along the height direction of the upper shell 310 is greater than the inner wall size of the notch 412 along the length direction of the upper shell 310. Among them, the inner wall size of the notch 412 along the height direction of the upper shell 310 is the line segment H marked in Figure 86, and the inner wall size of the notch 412 along the length direction of the upper shell 310 is the line segment L marked in Figure 86. When the length of the line segment H is greater than the length of the line segment L, the rotation of the notch 412 can cause the first arm 422 to be displaced, resulting in a certain unlocking stroke. In some embodiments, the notch 412 is L-shaped, including a vertical inner wall and a horizontal inner wall. For example, the size of the vertical inner wall is greater than the size of the horizontal inner wall to push the first arm 422 to slide forward.

[0497] FIG88 is a structural diagram 1 of an unlocker according to some embodiments; FIG89 is a structural diagram 2 of an unlocker according to some embodiments; and FIG90 is a cross-sectional structural diagram of an unlocker according to some embodiments. As shown in FIGS. 88-90, in some embodiments, the bending portion 424 is a hemispherical arm, the top surface of the bending portion 424 is a plane, and a hemispherical surface is formed downward around the top surface, so that the force-bearing surface between the bending portion 424 and the groove 413 is more concentrated, avoiding the existence of other force-bearing surfaces.

[0498] In some embodiments, the second arm 423 and the first arm 422 both extend relative to the end surface of the main body structure 421. For example, the relative extension length of the second arm 423 is greater than the relative extension length of the first arm 422. The longer extension length of the second arm 423 ensures that the bent portion 424 passes over the side of the boss 411 and extends to the groove 413. The relative extension length of the second arm 423 is the line segment n marked in FIG9, and the relative extension length of the first arm 422 is the line segment m marked in FIG88. Obviously, the length of the line segment n is greater than the length of the line segment n. The present disclosure uses two arms with different extension lengths to generate a progressive unlocking path, which is not only conducive to miniaturization of size, but also provides a longer unlocking stroke.

[0499] In some embodiments, the first arm 422 and the bending portion 424 extend in different directions. The first arm 422 extends in the same direction as the length of the main body structure 421 , and the bending portion 424 extends in the same direction as the width of the main body structure 421 .

[0500] In some embodiments, the lengths of the first arm 422 and the second arm 423 may be designed according to the expected unlocking stroke, so as to achieve the expected unlocking stroke and realize complete unlocking of the electrical port module 300 .

[0501] In some embodiments, in order to enable the unlocker 420 to slide along the upper shell 310 and thus move toward the locking component 318 and the spring piece 1061, a first slide groove 426 and a second slide groove 425 are respectively formed on both sides of the main body structure 421. As mentioned above, the surface of one end of the upper shell 310 close to the light port is disconnected to form a first flat plate 311 and a second flat plate 312 on both sides, respectively. The first flat plate 311 and the second flat plate 312 are arranged opposite to each other and are not connected, and there is a gap 319 therebetween, and the gap 319 is used to accommodate the unlocker 420. A first guide rail 313 is formed on the side wall of the first plate 311 facing the gap 319, and a second guide rail 314 is formed on the side wall of the second plate 312 facing the gap 319. The first slide groove 426 is slidably connected to the first guide rail 313, and the second slide groove 425 is slidably connected to the second guide rail 314. Therefore, when the unlocking handle 410 is pulled upward, under the action of the thrust, the first slide groove 426 slides along the first guide rail 313 toward the engaging component 318 and the spring piece 1061, and the second slide groove 425 slides along the second guide rail 314 toward the engaging component 318 and the spring piece 1061, so that the unlocking device 420 acts on the surface of the spring piece 1061 to lift the spring piece 1061, thereby unlocking the electrical port module 300. Exemplarily, the lengths of the first slide groove 426 and the second slide groove 425 depend on the unlocking stroke required for the electrical port module 300 to unlock.

[0502] When the electrical port module 300 is in a locked state, in order to prevent the electrical port module 300 from being unlocked, a certain distance should be maintained between the electrical port module 300 and the engaging part 318, and the unlocker 420 should have a preset length. In order to ensure the unlocking stroke, the length of the first slide groove 426 and the second slide groove 425 should have a preset length, and the length left for the first arm 422 is limited, and the end of the first arm 422 is connected to the surface of the boss 411, so the first arm 422 is limited between the boss 411 and the main body structure 421, which also leads to a shorter setting length of the first arm 422, which is a short arm; at the same time, it is necessary to ensure that the unlocker 420 is relatively closer to the unlocking handle 410 to lengthen the distance between the unlocker 420 and the engaging part 318 when the electrical port module 300 is in a locked state, and the setting length of the first arm 422 cannot be too long. Therefore, whether from the perspective of the mechanical setting relationship or the unlocking principle, the length of the first arm 422 cannot be too long.

[0503] In some embodiments, a first arm 422 and a bent portion 424 are formed at one end of the main body structure 421, and a connecting plane 428 is formed at the other end. A first inclined surface 429a and a second inclined surface 429b are formed at both ends of the connecting plane 428. When the electrical port module 300 needs to be unlocked, the unlocking handle 420 is rotated, and the unlocker 420 is driven to move toward the position where the engaging component 318 and the spring 1061 are located. Then, the first inclined surface 429a and the second inclined surface 429b also move toward the position where the engaging component 318 and the spring 1061 are located. During the movement, the first inclined surface 429a and the second inclined surface 429b are respectively in contact with the two sides of the spring 1061, and the thrust applied by the unlocking handle 410 acts on the first inclined surface 429a and the second inclined surface 429b. On the inclined surface 429b, according to the decomposition of the acting force, the thrust on the first inclined surface 429a and the second inclined surface 429b can be decomposed into a horizontal component and a vertical component that are perpendicular to each other. Under the action of the horizontal component, the unlocker 420 moves forward, and under the action of the vertical component, the spring piece 1061 is pushed upward. As the unlocking handle 410 rotates, the unlocker 420 is pushed forward. During the pushing process, the first inclined surface 429a and the second inclined surface 429b contact the spring piece 1061 and act on the spring piece 1061. The contact surface between the two inclined surfaces and the spring piece 1061 is gradually raised as the unlocker 420 moves forward, and the free end of the spring piece 1061 can be raised by the gradually raised contact surface until the spring piece 1061 is separated from the engaging component 318. Meanwhile, illustratively, the first inclined surface 429 a and the second inclined surface 429 b are not connected and have a certain gap therebetween so as to avoid the engaging component 318 when the engaging component 318 is released.

[0504] In some embodiments, the spring clip 1061 is in an inclined state. For example, the height of the free end of the spring clip 1061 is higher than the height of the fixed end of the spring clip 1061. In order to make the first inclined surface 429a and the second inclined surface 429b contact the spring clip 1061 from their bottom, thereby acting on the spring clip 1061, the height of the connecting plane 428 should be lower than the height of the main body structure 421, so that the surface where the first inclined surface 429a and the second inclined surface 429b are located is sunken, so that the first inclined surface 429a and the second inclined surface 429b are respectively in contact with the spring clip 1061 from the beginning, extending the contact time with the spring clip 1061, thereby ensuring that the spring clip 1061 is effectively lifted up and completely lifted up until the spring clip 1061 is separated from the locking component 318, thereby unlocking the electrical port module 300 from the host computer. To this end, a connecting slope 427 is connected between the main body structure 421 and the connecting plane 428, and the main body structure 421 and the connecting plane 428 are connected by the connecting slope 427, so as to ensure effective action on the spring piece 1061. Exemplarily, the connecting slope 427 is inclined so that the surface of the main body structure 421 is higher than the surface of the connecting plane 428, and the inclination angle of the connecting slope 427 can be determined according to the position of the engaging component 318.

[0505] FIG91 is a structural diagram of an upper shell according to some embodiments. As shown in FIG91 , in some embodiments, a first rotating shaft 315 is formed on one side of the first flat plate 311, and a second rotating shaft 316 is formed on one side of the second flat plate 312. The first rotating shaft 315 and the second rotating shaft 316 are both bent and extended relative to the side wall of the upper shell 310. Exemplarily, the extension directions of the two are consistent to facilitate the nesting of the unlocking handle 410. In order to limit the unlocking handle 410, a limiting groove 3161 is formed on the second rotating shaft 316, and a limiting structure is provided on the surface of the limiting groove 3161 to limit and fix the unlocking handle 410. Exemplarily, the limiting structure can be a limiting sheet.

[0506] FIG92 is a cross-sectional view of an electrical port module according to some embodiments. As shown in FIG92, in some embodiments, the main body structure 421 of the unlocker 420 is disposed between the first plate 311 and the second plate 312, the first plate 311 is formed with a first guide rail 313 on the side wall facing the gap 319, the second plate 312 is formed with a second guide rail 314 on the side wall facing the gap 319, and a first slide groove 426 and a second slide groove 425 are formed on both sides of the main body structure 421, the first slide groove 426 is slidably connected to the first guide rail 313, and the second slide groove 425 is slidably connected to the first guide rail 313. The second slide grooves 425 are slidably connected to the second guide rail 314. Therefore, when the unlocking handle 410 is pulled upward, under the action of the thrust, the first slide groove 426 slides along the first guide rail 313 toward the engaging component 318 and the spring piece 1061, and the second slide groove 425 slides along the second guide rail 314 toward the engaging component 318 and the spring piece 1061, so that the unlocker 420 acts on the surface of the spring piece 1061 to lift the spring piece 1061, thereby unlocking the electrical port module 300.

[0507] FIG93 is a structural diagram of an electrical port module end according to some embodiments. As shown in FIG93 , in some embodiments, in order to limit the unlocking handle 410, a limiting groove 3161 is formed on the second rotating shaft 316, and a limiting piece 317 is provided on the surface of the limiting groove 3161 to limit the unlocking handle 410 on the upper shell 310 to prevent the unlocking handle 410 from slipping out of the upper shell 310.

[0508] A first avoidance portion 416 is formed on one side of the second nesting hole 415 for avoiding the limiting piece 317 ; a second avoidance portion 417 is formed on one side of the first nesting hole 414 for avoiding the side wall of the upper shell 310 .

[0509] FIG94 is a diagram of an unlocking process of an unlocking component according to some embodiments. As shown in FIG94 , in some embodiments, when the unlocking handle 410 is rotated upward, the unlocking handle 410 pushes the unlocking device 420 to move forward to approach the engaging component 318 and the spring 1061, and the unlocking device 420 contacts the two sides of the spring 1061 through the first inclined surface 429a and the second inclined surface 429b respectively; during the forward movement of the unlocking device 420, the surfaces of the first inclined surface 429a and the second inclined surface 429b gradually act on the spring 1061, and the free end of the spring 1061 can be lifted up through the gradually rising contact surface until the spring 1061 is separated from the engaging component 318, thereby unlocking the electrical port module 300. Among them, "moving forward" means that the unlocking device 420 moves toward the position where the engaging component 318 is located.

[0510] When the unlocking handle 410 is in a naturally drooping state, the electrical port module 300 is inserted into the cage of the host computer. Since the distance between the unlocking device 420 and the spring 1061 is relatively far, the unlocking device 420 cannot act on the spring 1061. Therefore, the electrical port module 300 is kept locked. When the unlocking handle 410 is pulled to a higher height, the unlocking device 420 contacts the spring 1061 and acts on the spring 1061 until the spring 1061 is lifted up, thereby unlocking the electrical port module 300.

[0511] FIG95 is a schematic diagram of an unlocking principle of an unlocking component according to some embodiments. As shown in FIG95 , the process shown is the process of interaction between the notch 412 and the first arm 422 during the process of rotating the unlocking handle 410 to unlock. Before the unlocking handle 410 is pulled, the first arm 422 is arranged in the notch 412 to maintain the stability of the unlocker 420. As the unlocking handle 410 is gradually lifted, the opening of the notch 412 gradually moves downward. During this movement, the first rounded corner 4122 of the notch 412 supports the first arm 422 to move forward. The notch 412 exerts pressure on the first arm 422. Under the pressure, the first arm 422 moves forward until it is separated from the notch 412, and then moves forward by the side wall 418. When the first arm 422 is no longer in contact with the side wall 418, the first arm 422 is no longer squeezed and cannot continue to push the first arm 422 to move forward. For example, the notch 412 and the first arm 422 may be disconnected at some point due to vertical misalignment, such as the first arm 422 being located diagonally above the notch 412 , so that the unlocker 420 cannot be pushed forward any further.

[0512] FIG96 is a second schematic diagram of an unlocking principle of an unlocking component according to some embodiments. As shown in FIG96 , the process shown is the process of interaction between the groove 413 and the bent portion 424 during the process of pulling the unlocking handle 410 to unlock. Before the unlocking handle 410 is pulled, the groove 413 and the bent portion 424 cannot contact each other, otherwise a certain unlocking stroke will be generated for the electrical port module 300, destroying the locked state of the electrical port module 300 at this time. As the unlocking handle 410 is gradually lifted, the opening of the groove 413 rotates upward, and the curved surface 4133 begins to contact the bent portion 424, pushing the bent portion 424 to move toward the second fillet 4132. As the unlocking handle 410 continues to rotate, the bent portion 424 contacts the second fillet 4132, and the two also make tangential motion. With the tangent point of the two as the fulcrum, the bent portion 424 is moved toward the second accommodating cavity 4131. The rotating second accommodating cavity 4131 squeezes the bent portion 424, thereby causing the second arm 423 to move forward and driving the main body structure 421 to move at the same time, until the unlocking device 420 completely lifts the spring piece 1061 and completely separates the spring piece 1061 from the engaging component 318, thereby releasing the engaging relationship between the electrical port module 300 and the host computer, separating the electrical port module 300 from the host computer, and realizing the unlocking of the electrical port module 300.

[0513] In some embodiments, as the unlocking handle 410 is gradually lifted, the curved surface 4133 begins to contact the bending portion 424. At this time, the first arm 422 is still connected to the notch 412, that is, the time point when the notch 412 is disconnected from the first arm 422 is later than the time point when the curved surface 4133 and the bending portion 424 are in contact with each other, so as to ensure the continuity of unlocking.

[0514] FIG. 97 is a first diagram of an unlocking component in an initial unlocking state according to some embodiments; FIG. 98 is a second diagram of an unlocking component in an initial unlocking state according to some embodiments. As shown in FIG. 97 and FIG. 98, before the unlocking handle 410 is pulled, the first arm 422 is disposed in the notch 412 to maintain the stability of the unlocker 420. Before the unlocking handle 410 is pulled, the groove 413 and the bent portion 424 cannot come into contact with each other, otherwise a certain unlocking stroke will be generated for the electrical port module 300, destroying the locked state of the electrical port module 300 at this time.

[0515] FIG99 is a first diagram of an unlocking intermediate state of an unlocking component according to some embodiments; FIG100 is a second diagram of an unlocking intermediate state of an unlocking component according to some embodiments. As shown in FIG99 and FIG100, as the unlocking handle 410 rotates, the opening of the groove 413 rotates upward, the curved surface 4133 begins to contact the bent portion 424, and the curved surface 4133 squeezes the bent portion 424, thereby pushing the bent portion 424 to move toward the second fillet 4132. As the unlocking handle 410 continues to rotate, the bent portion 424 contacts the second fillet 4132, and the two also move tangentially. With the tangent point of the two as the fulcrum, the bent portion 424 is moved toward the second accommodating cavity 4131, and the second accommodating cavity 4131 squeezes the bent portion 424, so that the bent portion 424 pushes the unlocking device 420 toward the direction of the engaging component 318 and the spring 1061.

[0516] FIG101 is a first diagram of the final unlocking state of an unlocking component according to some embodiments; FIG102 is a second diagram of the final unlocking state of an unlocking component according to some embodiments; and FIG103 is a third diagram of the final unlocking state of an unlocking component according to some embodiments. As shown in FIGS. 101-103, when unlocking is completed, the bent portion 424 is in the groove 413, and at this time, the first arm 422 has broken contact with the notch 412 and is no longer connected.

[0517] The electrical port module provided by the present disclosure includes an upper shell and an unlocking component. The surface of the upper shell has a snap-fit ​​component, which is snap-fitted with the spring of the upper computer through the snap-fit ​​component, so that the electrical port module is snapped into the upper computer. The unlocking component includes an unlocking handle and an unlocker, wherein the unlocking handle is arranged at the end of the upper shell and is rotatably connected to the upper shell, one end of the unlocking handle is formed with a notch, and the other end is formed with a groove, and both the notch and the groove rotate with the rotation of the unlocking handle. The unlocker is slidably connected to the upper shell, and the unlocker includes a body structure, and the end surface of the body structure extending toward the unlocking handle is respectively formed with a first arm and a second arm. The first arm is arranged in the notch, and the second arm includes an extension arm and a bending portion formed by bending the end of the extension arm. As the notch rotates, the notch presses the first arm, so that the first arm slides along the inner wall of the notch until it slips out of the notch, and then the side wall connected to the notch continues to abut, so that the first arm moves toward the snap-fit ​​component. When the electrical port module is in a locked state, the first arm is arranged in the notch. In order to prevent the unlocker from acting on the spring sheet and the engaging part at this time, the length of the first arm is relatively short, so that the unlocker is as far away from the spring sheet and the engaging part as possible in the current state, thereby maintaining the current locked state. When the length of the first arm is relatively short, during the movement, the first arm and the notch will be disconnected due to the offset, until the first arm and the abutting side wall will also be disconnected due to the offset, so that the first arm is no longer squeezed and no unlocking stroke is generated. Therefore, as the first arm moves, the bent portion of the second arm enters the groove, and the inner wall of the groove squeezes the bent portion during the rotation of the groove, so that the second arm moves toward the engaging part and continues to generate an unlocking stroke until the spring sheet is lifted up, so that the engaging part and the spring sheet are separated, thereby releasing the engaging connection between the electrical port module and the host computer. In the present disclosure, the first arm and the second arm are respectively subjected to force, providing a continuous and sufficient unlocking stroke, completely separating the electrical port module from the host computer, and realizing the unlocking of the electrical port module. It can be understood that the optical module is a type of electrical port module, and the unlocking component provided in the present disclosure is also applicable to the optical module, that is, the optical module can also adopt the unlocking component provided in the present disclosure.
