Description

Technical Field

[0001] This application relates to the field of optical communication technologies, and particularly to an optical module. Background Art

[0002] With the development of new services and application models such as cloud computing, mobile Internet, and video, the development and progress of optical communication technologies have become increasingly important. In optical communication technologies, an optical module is a tool for realizing the mutual conversion of optical and electrical signals and is one of the key components in optical communication devices.

[0003] Generally, the optical module is inserted into the cage of the host computer and is locked and fixedly connected to the cage of the host computer to ensure the stability of the electrical connection between the optical module and the host computer; when it is necessary to pull out the optical module from the host computer, it is necessary to unlock the optical module and the cage of the host computer. Summary of the Invention

[0004] An embodiment of this application provides an optical module to solve the problem of unlocking the optical module and the cage of the host computer.

[0005] This application provides an optical module, including:

[0006] An upper housing;

[0007] A lower housing, which is covered with the upper housing to form a receiving cavity. A circuit board and an optical transceiver component are arranged in the receiving cavity, and the optical transceiver component is electrically connected to the circuit board; the lower housing includes:

[0008] A first wall surface;

[0009] A second wall surface, which is connected to one end of the first wall surface and is recessed from the first wall surface. A locking portion is provided on the second wall surface; the locking portion is configured to establish a locking relationship with the outside;

[0010] An unlocking component, which is movably arranged in the lower housing along the length direction of the lower housing, and the unlocking component extends from the first wall surface to the second wall surface; the unlocking component includes:

[0011] A body, which is arranged on the first wall surface;

[0012] A pushing member, which is connected to one end of the body, and the pushing member is inclined relative to the body;

[0013] A force-applying member, which is connected to the end of the pushing member facing the locking portion. When the unlocking component moves towards the first wall surface, the pushing member moves from the second wall surface towards the first wall surface, so that the force-applying member moves away from the lower housing, thereby unlocking the locking relationship between the locking portion and the outside;

[0014] The outer cover plate is disposed on the first wall surface and is located on the side of the unlocking component facing away from the lower housing. There is an activity gap for the unlocking component to move between the outer cover plate and the lower housing. A first protrusion is provided on the side of the outer cover plate facing the pushing member. During the process of the unlocking component moving towards the second wall surface, the first protrusion is configured to selectively abut against the pushing member, so that the first protrusion pushes the unlocking component towards the lower housing.

[0015] In the optical module provided by the embodiment of the present application, the upper housing and the lower housing are covered to form an accommodation cavity, and the circuit board and the optical transceiver component are arranged in the accommodation cavity, which facilitates 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 provided on the lower housing. The second wall surface is recessed from the first wall surface, and a locking portion is provided on the second wall surface. In this way, when the optical module is inserted into the host computer, the locking portion on the second wall surface establishes a locking relationship with the outside, for example, locks with the locking structure on the host computer cage. In the embodiment of the present application, the body of the unlocking component is arranged on the first wall surface, the pushing member of the unlocking component is inclined 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 it is necessary to pull out the optical module from the host computer, the unlocking component can be moved towards the first wall surface, the pushing member moves from the second wall surface towards the first wall surface, and pushes the whole unlocking component to move away from the lower housing, so that the force applying member pushes the locking structure on the host computer cage away from the locking portion, thereby unlocking the locking portion. In addition, an outer cover plate is covered on the first wall surface and is covered on the side of the unlocking component facing away from the lower housing. In this way, the outer cover plate limits the unlocking component on the lower housing and allows it to move along the length direction of the lower housing. There is an activity gap for the unlocking component between the outer cover plate and the lower housing, which facilitates the pushing member to move from the second wall surface towards the first wall surface when the unlocking component moves towards the first wall surface, so as to push the whole unlocking component in the direction away from the lower housing, that is, it is convenient for the force applying member to apply a force to the locking structure of the host computer cage. In the embodiment of the present application, a first protrusion is provided on the side of the outer cover plate facing the pushing member. During the process of the unlocking component moving back to the second wall surface to reset, the first protrusion can selectively abut against the pushing member. In this way, the first protrusion has a force facing the lower housing on the pushing member, so that the unlocking component moves towards the lower housing while resetting towards the second wall surface, so that the force applying member can move along the second wall surface during the reset process of the unlocking component from the first preset position, which is convenient for the force applying member to be inserted under the locking structure of the host computer cage, facilitates the normal reset of the unlocking component, and can be smoothly unlocked during the next unlocking, improving the smoothness and stability of the unlocking of the unlocking component.

[0042] The technical solutions in some embodiments of the present application will be clearly and detailedly described below in conjunction with the accompanying drawings. Apparently, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments provided in the present application fall within the protection scope of the present application.

[0043] In optical communication technology, in order to establish information transmission between information processing devices, it is necessary to load information onto light and utilize the propagation of light to achieve information transmission. Here, the light loaded with information is an optical signal. When the optical signal is transmitted in an information transmission device, the loss of optical power can be reduced, so that high-speed, long-distance, and low-cost information transmission can be achieved. The signals that information processing devices can recognize and process are electrical signals. Information processing devices generally include optical network units (ONUs), gateways, routers, switches, mobile phones, computers, servers, tablet computers, televisions, etc., and information transmission devices generally include optical fibers and optical waveguides, etc.

[0044] An optical module can realize the mutual conversion between optical signals and electrical signals between an information processing device and an information transmission device. 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 unit; 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 unit; the second electrical signal from the optical network unit 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 information can be transmitted between multiple information processing devices through electrical signals, at least one of the multiple information processing devices needs to be directly connected to the optical module, rather than all the information processing devices being directly connected to the optical module. Here, the information processing device directly connected to the optical module is called the host 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.

[0045] Figure 1 It is a partial structural diagram of an optical communication system provided according to an embodiment of the present application. Refer to Figure 1 As shown, 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 external optical fiber 101, and a network cable 103.

[0046] One end of the external optical fiber 101 extends in the direction of the remote information processing device 1000, and the other end of the external 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 external 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 external 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 and low-power-loss information transmission.

[0047] The optical communication system may include one or more external optical fibers 101, and the external optical fiber 101 is detachably or fixedly connected to the optical module 200. The host computer 100 is configured to provide a data signal to the optical module 200, or receive a data signal from the optical module 200, or monitor or control the working state of the optical module 200.

[0048] The host computer 100 includes a housing generally in the shape of a cuboid, and an optical module interface 102 provided on the housing. The optical module interface 102 is configured to access the optical module 200 to establish a unidirectional or bidirectional electrical signal connection between the host computer 100 and the optical module 200.

[0049] The host computer 100 further includes an external power interface, which can access an electrical signal network. For example, the external power interface includes a Universal Serial Bus (USB) interface or a network cable interface 104. The network cable interface 104 is configured to access a 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, a third electrical signal sent by the local information processing device 2000 is transmitted into the host computer 100 through the network cable 103. 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. The optical module 200 converts the second electrical signal into a second optical signal and transmits the second optical signal to the external optical fiber 101. The second optical signal is transmitted in the external optical fiber 101 to the remote information processing device 1000. For example, a first optical signal from the remote information processing device 1000 propagates through the external optical fiber 101. The first optical signal from the external optical fiber 101 is transmitted to the optical module 200. The optical module 200 converts the first optical signal into a first electrical signal. The optical module 200 transmits the first electrical signal to the host computer 100. The host computer 100 generates a fourth electrical signal according to the first electrical signal and transmits the fourth electrical signal into the local information processing device 2000. It should be noted that an optical module is a tool for realizing the mutual conversion between optical signals and electrical signals. During the above conversion process of optical signals and electrical signals, the information does not change, but the encoding and decoding methods of the information may change.

[0050] In addition to including an optical network terminal, the host computer 100 further includes an Optical Line Terminal (OLT), an Optical Network Terminal (ONT), or a data center server, etc.

[0051] Figure 2 It is a partial structure diagram of the host computer according to an embodiment of the present application. To clearly show the connection relationship between the optical module 200 and the host computer 100, Figure 2 only the structure of the host computer 100 related to the optical module 200 is shown. Referring to Figure 2 as shown, the host computer 100 further includes a PCB circuit board 105 disposed in the housing, a cage 106 disposed on the surface of the PCB circuit board 105, a radiator 107 disposed on the cage 106, and an electrical connector disposed inside the cage 106. The electrical connector is configured to access the electrical port of the optical module 200; the radiator 107 has raised structures such as fins for increasing the heat dissipation area.

[0052] 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 conducted 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 as to establish a two-way electrical signal connection between the optical module 200 and the host computer 100. In addition, the optical port of the optical module 200 is connected to the external optical fiber 101, so as to establish a two-way optical signal connection between the optical module 200 and the external optical fiber 101.

[0053] Figure 3 It is a schematic structural diagram of the optical module provided by the embodiment of the present application. Figure 4 It is an exploded structural schematic diagram of the optical module provided by the embodiment of the present application. Refer to Figure 3 and Figure 4 As shown in

[0054] Refer to Figure 3 and Figure 4 As shown, the upper housing 201 covers the lower housing 202 to form a receiving cavity with two openings between the upper housing 201 and the lower housing 202. The overall contour of the receiving cavity can be a cuboid structure. In some examples, the lower housing 202 includes a bottom plate and two side plates located on both sides of the bottom plate and perpendicular to the bottom plate.

[0055] The two openings can be two openings at both ends in the same direction. For example, refer to Figure 3 As shown, the two openings can be located at both ends of the optical module along the length direction of the optical module (such as the direction shown by the x-axis in Figure 3 ); in some examples, the two openings can also be located in different directions. For example, refer to Figure 3 As shown, one of the openings can be located at one end of the optical module along the length direction of the optical module, and the other opening can be located on one side of the optical module along the width direction of the optical module (such as the direction shown by the y-axis in Figure 3 ). In the embodiment of the present application, one of the openings can be the electrical port 203, and the gold fingers of the circuit board 300 extend out from the electrical port 203 and are inserted into the host computer; the other opening can be the optical port 204 for external optical fiber access to connect to the optical transceiver component 400 inside the optical module; optoelectronic devices such as the circuit board 300 and the optical transceiver component 400 can be arranged in the receiving cavity and wrapped by the receiving cavity.

[0056] In the embodiments of the present application, an assembly method of combining an upper housing 201 and a lower housing 202 is adopted, which facilitates the installation of devices such as a circuit board 300 and an optical transceiver component 400 into the housing, and the upper housing 201 and the lower housing 202 form a package protection housing for the outer layer of the optical module; the upper housing 201 and the lower housing 202 are generally made of metal materials, which is conducive to achieving electromagnetic shielding and heat dissipation.

[0057] In some examples of the embodiments of the present application, to ensure that a stable connection relationship can be formed between the optical module and the host computer after the optical module is inserted into the host computer, a locking portion 20221 is usually provided on the outer wall surface of the lower housing 202, and the locking portion 20221 is used for a fixed connection with the host computer. For example, the locking portion 20221 can be snap-connected to the locking structure of the host computer. Among them, there is a locking spring piece in the host computer cage 106, and the locking spring piece cooperates with the locking portion 20221 to achieve the locking of the optical module and the host computer.

[0058] The unlocking component 600 can be arranged on the outer wall of the lower housing 202 to achieve the unlocking between the optical module and the host computer, that is, to release the fixed connection between the optical module and the host computer. In some examples, when unlocking, the unlocking component 600 pushes the locking spring piece, so that the locking spring piece is separated from the locking portion 20221, thereby releasing the locking relationship between the optical module and the host computer, and facilitating the extraction or removal of the optical module from the cage of the host computer.

[0059] In some examples, circuit traces, electronic components, and chips are arranged on the circuit board 300. The electronic components and chips are connected according to the circuit design through the circuit traces to achieve functions such as power supply, electrical signal transmission, and grounding. The electronic components can include, for example, capacitors, resistors, triodes, and metal-oxide-semiconductor field-effect transistors (MOSFETs). The chips can include, for example, a microcontroller unit (MCU), a laser driver chip, a transimpedance amplifier (TIA), a limiting amplifier (LA), a clock and data recovery chip (CDR), a power management chip, and a digital signal processing (DSP) chip.

[0060] The circuit board 300 is generally a rigid circuit board 300. Due to its relatively hard material, the rigid circuit board 300 can also achieve a bearing function. For example, the rigid circuit board 300 can stably bear the above-mentioned electronic components and chips; the rigid circuit board 300 can also be inserted into the electrical connector in the cage 106 of the host computer 100.

[0061] The circuit board 300 further includes a gold finger 301 formed on its end surface. The gold finger 301 is composed of a plurality of independent pins. The circuit board 300 is inserted into the cage 106, and is electrically connected to the electrical connector in the cage 106 through the gold finger 301. The gold finger 301 can be disposed only on the surface of one side of the circuit board 300 (such as Figure 4 the upper surface shown), or can be disposed on the upper and lower surfaces of the circuit board 300 to provide a larger number of pins, so as to adapt to occasions with a large demand for the number of pins. The gold finger 301 is configured to establish an electrical connection with the host computer to achieve power supply, grounding, two-wire synchronous serial (Inter-Integrated Circuit, I2C) signal transmission, data signal transmission, etc. Of course, the flexible circuit board 300 is also used in some optical modules. The flexible circuit board 300 is generally used in cooperation with the rigid circuit board 300 as a supplement to the rigid circuit board 300.

[0062] The optical transceiver component 400 is electrically connected to the circuit board 300. The optical transceiver component 400 can include an optical emission component and an optical reception component. Among them, the optical emission component can emit an optical signal, for example, convert the electrical signal transmitted by the circuit board 300 into an optical signal and transmit the optical signal to the external optical fiber; the optical reception component can receive an optical signal, for example, receive the optical signal transmitted by the external optical fiber. In some examples, the optical emission component and the optical reception component can be combined together or separated from each other.

[0063] Figure 5 FIG. is a schematic structural diagram of the unlocking component cooperating with the lower housing in the optical module provided by the embodiment of the present application. Figure 6 FIG. is an exploded structural diagram of the unlocking component cooperating with the lower housing in the optical module provided by the embodiment of the present application. Referring to Figure 5 and Figure 6 As shown, for the convenience of installing the optical transceiver component and the circuit board and improving the compactness of the optical module structure, in some examples of the embodiment of the present application, the lower housing 202 includes: a first wall surface 2021 and a second wall surface 2022. Among them, the second wall surface 2022 is connected to one end of the first wall surface 2021, and the second wall surface 2022 is recessed from the first wall surface 2021. In the embodiment of the present application, the locking portion 20221 can be disposed on the second wall surface 2022.

[0064] In some examples, it can also be understood that the first wall surface 2021 protrudes outward from the second wall surface 2022, that is to say, one end of the lower housing 202 is thicker than the other end; in this way, the optical transceiver component can be arranged at the thicker end, for example, arranged inside the first wall surface 2021, while the circuit board itself is thinner and occupies less space, and can be arranged inside the second wall surface 2022; in this way, the circuit board in the optical module has a compact structure inside the housing; when connected to the host computer, the second wall surface 2022 can be inserted into the host computer, in this way, the space occupied by the host computer is relatively small.

[0065] In some alternative examples of the embodiments of the present application, the first wall surface 2021 and the second wall surface 2022 can be integrally formed, for example, integrally cast. Among them, the locking portion 20221 can be a protruding portion on the second wall surface 2022. In some examples, the locking portion 20221 and the second wall surface 2022 can also be integrally formed. As an alternative example, the side of the locking portion 20221 facing away from the first wall surface 2021 (that is, the side of the locking portion 20221 facing the host computer during the insertion of the optical module into the host computer) can be an inclined wall 20222, so that it is convenient for the locking structure on the host computer to cross the locking portion 20221 and be snapped on the side of the locking portion 20221 facing the first wall surface 2021, improving the smoothness of the insertion of the optical module into the host computer.

[0066] In some examples of the embodiments of the present application, the unlocking component 600 can be movably arranged on the lower housing 202 along the length direction of the lower housing 202 (for example Figure 6 the direction shown by the x-axis in the figure), and the unlocking component 600 extends from the first wall surface 2021 to the second wall surface 2022. In some examples, the unlocking component 600 can be a sheet metal part, that is to say, the unlocking component 600 can also be made of a metal material. In the embodiments of the present application, the unlocking component 600 includes a body 601, a pushing member 602 and a force applying member 603.

[0067] In some examples, the body 601 can be arranged on the first wall surface 2021. In some alternative examples, a limiting groove can be arranged on the first wall surface 2021 along the length direction, and the body 601 is arranged in the limiting groove and moves along the limiting groove. In some other examples, limiting ribs can also be arranged on the first wall surface 2021 along the length direction. Two limiting ribs can be arranged, and the two limiting ribs are arranged at intervals along the width direction of the lower housing 202 (for example Figure 6 the direction shown by the y-axis in the figure), and the body 601 can be arranged in the gap between the two limiting ribs and move along the groove defined by the two limiting ribs.

[0068] In some examples of the embodiments of the present application, the pushing member 602 is connected to one end of the main body 601 facing the second wall surface 2022, and the pushing member 602 is inclined with respect to the main body 601 towards the second wall surface 2022. The pushing member 602 may extend from the end of the main body 601 towards the second wall surface 2022, and the pushing member 602 extends along the height direction of the lower housing 202 (for example Figure 6 the direction shown by the negative z-axis in

[0069] ), so that the pushing member 602 is inclined with respect to the main body 601. It can be understood that in some examples of the embodiments of the present application, the unlocking member 600 may be a sheet metal part. Therefore, in some examples, the pushing member 602 may be formed by bending one end of the unlocking member 600 facing the second wall surface 2022. That is to say, the pushing member 602 and the main body 601 may be an integral structure; in this way, it is convenient for the processing and production of the unlocking member 600, and the processing production cost of the unlocking member 600 is saved.

[0070] To limit the unlocking member 600 on the lower housing 202, the optical module provided in the embodiments of the present application further includes an outer cover plate 700. The outer cover plate 700 is covered on the first wall surface 2021 and is located on the side of the unlocking member 600 facing away from the lower housing 202; for example, the outer cover plate 700 may be covered on the lower side wall of the lower housing 202.

[0071] In some embodiments of the present application, there is an activity gap for the unlocking member 600 to move between the outer cover plate 700 and the lower housing 202. In some examples, the activity gap may be the distance between the outer cover plate 700 and the bottom wall of the limiting groove. That is to say, the unlocking member 600 moves between the bottom wall of the limiting groove and the inner wall of the outer cover plate 700.

[0072] Figure 7 FIG. is a schematic structural view of the lower housing in the optical module provided according to the embodiments of the present application. Figure 8 is Figure 7 a partial enlarged view of part A in Figure 9 FIG. is another schematic structural view of the lower housing in the optical module provided according to the embodiments of the present application. Figure 10 FIG. is a schematic structural view of the cooperation between the lower housing and the unlocking member in the optical module provided according to the embodiments of the present application. Refer to Figures 7 - 10As shown, in some examples of the embodiments of the present application, the lower housing 202 further includes a third wall surface 2023, which is connected between the first wall surface 2021 and the second wall surface 2022, and the third wall surface 2023 is used to abut against the upper computer housing. In some embodiments, the third wall surface 2023 may be a stepped surface between the first wall surface 2021 and the second wall surface 2022.

[0073] In some examples, the first wall surface 2021 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 oppositely arranged on both sides of the first bottom plate 20211. In some embodiments of the present application, the outer surface of the first bottom plate 20211 is provided with a first recess 20214 and a second recess 20215, the second recess 20215 is recessed in the first recess 20214, the second recess 20215 penetrates through to the third wall surface 2023, and the unlocking member is arranged in the second recess 20215. In some examples, the first recess 20214 may be located in the middle of the first recess 20214 along the width direction of the first bottom plate 20211, and the second recess 20215 is communicated with the first recess 20214. In some embodiments of the present application, the unlocking member is arranged in the second recess 20215, that is to say, in the embodiments of the present application, the unlocking member is limited by the second recess 20215. Among them, the width of the second recess 20215 may be adapted to the width of the unlocking member, for example, the width of the second recess 20215 may be equal to or close to the width of the unlocking member. In some examples of the embodiments of the present application, it may be that the body 601 is located in the second recess 20215.

[0074] In some embodiments, the first recess 20214 includes a first sub-recess 2141 and a second sub-recess 2142, the first sub-recess 2141 is communicated with the second recess 20215, the second sub-recess 2142 extends to the third wall surface 2023, and the second sub-recess 2142 is communicated with the first sub-recess 2141, the second recess 20215, and the third wall surface 2023. That is to say, the shape of the first recess 20214 may be in a "convex" shape, and the second sub-recess 2142 is located between the first sub-recess 2141 and the second wall surface 2022.

[0075] In some examples of the embodiments of the present application, the second recess 20215 has a first bottom wall surface 2151 and a pushing wall surface 2152; the first bottom wall surface 2151 protrudes from the second wall surface 2022; that is to say, there is still a certain height difference between the first bottom wall surface 2151 and the second wall surface 2022. The pushing wall surface 2152 is connected between the first bottom wall surface 2151 and the second wall surface 2022, and the pushing wall surface 2152 is inclined. Wherein, the inclination mode of the pushing wall surface 2152 and the inclination mode of the pushing member 602 can be the same or similar. In some specific examples, the pushing wall surface 2152 can be formed by chamfering a part of the third wall surface 2023 between the first wall surface 2021 and the second wall surface 2022 (for example, cutting off the right-angle edge formed after the second recess 20215 penetrates through to the third wall surface 2023), thereby forming the pushing wall surface 2152.

[0076] Or, 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 2022, and the first bottom wall surface 2151 and the second bottom wall surface 2156 are transitioned through the slope.

[0077] In some alternative examples, the pushing wall surface 2152 can be a straight wall surface; in some other alternative examples, the pushing wall surface 2152 can also be an arc-shaped wall surface. It can be understood that when the pushing wall surface 2152 is an arc-shaped wall surface, the arc-shaped wall surface can be a convex arc surface. In the embodiments of the present application, the pushing wall surface 2152 is taken as an example of a straight wall surface for illustration.

[0078] In some examples, there is a first included angle between the pushing wall surface 2152 and the second wall surface 2022, and there is a second included angle between the pushing member 602 and the second wall surface 2022; wherein, the first included angle is greater than the second included angle, so that when the unlocking member 600 moves towards the first wall surface 2021, the end of the pushing member 602 facing the second wall surface 2022 abuts against the pushing wall surface 2152.

[0079] In some alternative examples, the first included angle can be 150°-160°. For example, the first included angle can be 150°, 155° or 160°. The second included angle can be 135°-150°. For example, the first included angle can be 135°, 140°, 145° or 150°.

[0080] It should be noted here that the numerical values and numerical ranges involved in the embodiments of the present application are approximate values. Affected by the manufacturing process, there may be a certain range of errors, and this part of the errors can be considered negligible by those skilled in the art.

[0081] In the embodiment of the present application, the first angle between the push-up wall surface 2152 and the second wall surface 2022 is set to be greater than the second angle between the push-up member 602 and the second wall surface 2022; in this way, when the unlocking component 600 moves toward the first wall surface 2021, 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 application, 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 provided 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 2022; a positioning column 6012 is provided at the end of the accommodating through hole 6011 facing the second wall surface 2022; in some embodiments of the present application, 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 2022, the reset member 607 provides a reset force facing the second wall surface 2022 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 2022.

[0082] 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 application, the reset member 607 can be an elastic member such as a spring or a sponge column, 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 2021, 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 2022.

[0083] 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 2021, 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 2022.

[0084] In the embodiment of the present application, by providing an accommodation through-hole 6011 on the unlocking component and a limiting post 2153 on the first bottom wall surface 2151, the limiting post 2153 passes through the accommodation through-hole 6011 and the limiting post 2153 is located at one end of the accommodation through-hole 6011 facing away from the second wall surface 2022. In this way, when the reset member 607 is provided, the reset member 607 can be accommodated in the accommodation through-hole 6011, which can reduce the space size occupied by the reset member 607, thereby facilitating the miniaturization of the optical module. In addition, the limiting post 2153 is provided at one end of the accommodation through-hole 6011 facing away from the second wall surface 2022, and a positioning post 6012 is provided at one end of the accommodation through-hole 6011 facing the second wall surface 2022. In this way, one end of the reset member 607 only needs to be sleeved on the outer periphery of the positioning post 6012, and the other end of the reset member 607 abuts against the limiting post 2153, which is convenient for the installation of the reset member 607 and improves the assembly efficiency of the optical module.

[0085] In some other examples of the embodiment of the present application, the second recess 20215 further has a first limiting wall surface 2154 and a second limiting wall surface 2155. The first limiting wall surface 2154 and the second limiting wall surface 2155 are oppositely arranged on both sides of the first bottom wall surface 2151 in the width direction. The first limiting wall surface 2154 is recessed to form a first limiting groove 21541, and the first sub-bottom wall surface 21542 of the first limiting groove 21541 is recessed from the first bottom wall surface 2151. The second limiting wall surface 2155 is recessed to form a second limiting groove 21551, and the second sub-bottom wall surface 21552 of the second limiting groove 21551 is recessed from the first bottom wall surface 2151. The first limiting groove 21541 and the second limiting groove 21551 are located on both sides of the limiting post 2153. The body 601 is limited between the first limiting wall surface and the second limiting wall surface.

[0086] The first limiting groove 21541 and the second limiting groove 21551 can be oppositely arranged. Among them, 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 pushing member 602, and the force applying member 603 can be the same to facilitate the movement of the unlocking component 600 in the second recess 20215.

[0087] In some alternative examples of the embodiments of the present application, a third recess 2121 is provided on the outer surface of the first side plate 20212, and a fourth recess 2131 is provided on the surface of the second side plate 20213. A plurality of first card slots 21211 arranged side by side are formed by the depression of the third recess 2121, and a plurality of second card slots 21311 arranged side by side are formed by the depression of the fourth recess 2131. Among them, the third recess 2121 communicates with the first recess 20214, and the fourth recess 2131 also communicates with the first recess 20214.

[0088] In some embodiments of the present application, the first card slot 21211 can be formed by stamping the side wall of the third recess 2121 inward. The first card slot 21211 can be provided with two, three, four, etc. In the embodiments of the present application, the number of the first card slots 21211 is not limited. Among them, the setting method of the second card slot 21311 can be the same as or similar to that of the first card slot 21211, and this will not be elaborated in the embodiments of the present application. In some examples, the second card slot 21311 can be symmetrically arranged with the first card slot 21211. In this way, the positioning process when setting the first card slot 21211 and the second card slot 21311 can be reduced, and the processing efficiency can be improved.

[0089] In some other alternative examples of the embodiments of the present application, the second recess 20215 further has a second bottom wall surface 2156, a third limiting wall surface 2157 and a fourth limiting wall surface 2158. The second bottom wall surface 2156 is located at one end of the first bottom wall surface 2151 facing away from the second wall surface 2022, and the second bottom wall surface 2156 is recessed from the first bottom wall surface 2151; the third limiting wall surface 2157 and the fourth limiting wall surface 2158 are located on both sides of the second bottom wall surface 2156 along the width direction of the second bottom wall surface 2156. The third limiting wall surface 2157 is recessed from the first limiting wall surface 2154, and the fourth limiting wall surface 2158 is recessed from the second limiting wall surface 2155. That is to say, there is a certain height difference between the second bottom wall surface 2156 and the first bottom wall surface 2151, and the width between the third limiting wall surface 2157 and the fourth limiting wall surface 2158 is greater than the width between the first limiting wall surface 2154 and the second limiting wall surface 2155.

[0090] In some examples, there is a transition inclined surface 2159 between the second bottom wall surface 2156 and the first bottom wall surface 2151. That is to say, the transition inclined surface 2159 is not perpendicular to both the first bottom wall surface 2151 and the second bottom wall surface 2156. In this way, the influence of the height difference between the first bottom wall surface 2151 and the second bottom wall surface 2156 on the movement of the rubber-coated handle can be reduced, and the smoothness of the unlocking component moving in the second recess 20215 can be effectively improved.

[0091] To ensure that when the unlocking component is in the reset state, that is, when the optical module and the host computer are in the locked state, the force-applying member 603 is located between the second wall surface 2022 and the locking spring piece of the host computer, and at the same time reduce the overall size of the optical module. In some embodiments of the present application, along the width direction of the lower housing 202, sinking grooves 20223 are provided on both sides of the locking portion 20221. The sinking grooves 20223 are recessed from the second wall surface 2022. The side wall of the sinking groove 20223 facing the first wall surface 2021 is a sloped wall surface 20224. In some examples, when the unlocking component 600 is in the reset state, the force-applying member 603 can sink into the sinking groove 20223.

[0092] By providing the sinking grooves 20223 on both sides of the locking portion 20221, the sinking grooves 20223 are recessed from the second wall surface 2022; 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 surface 2022, which can reduce the gap between the force-applying member 603 and the second wall surface 2022, thereby reducing the gap between the locking spring piece of the host computer and the second wall surface 2022, and improving the locking stability between the optical module and the host computer.

[0093] In some embodiments of the present application, the sloped wall surface 20224 is not perpendicular to both the second wall surface 2022 and the bottom wall of the sinking groove 20223. In this way, a sloped wall surface 20224 is formed on the side of the sinking groove 20223 facing the first wall surface 2021. When the unlocking component 600 moves in the direction of the first wall surface 2021, the force-applying member 603 moves outwards from the sinking groove 20223 along the sloped wall surface 20224, which can reduce the moving resistance of the force-applying member 603 and improve the smoothness of the movement of the unlocking component 600.

[0094] In some examples, the inclined wall surface can be a straight inclined surface; or, in other examples, the sloped wall surface 20224 can also be a convex arc wall surface. The embodiments of the present application do not limit the type of the inclined wall surface.

[0095] Figure 11 FIG. is a schematic structural diagram of an unlocking component in an optical module provided according to an embodiment of the present application. Figure 12 FIG. is another schematic structural diagram of an unlocking component in an optical module provided according to an embodiment of the present application. To prevent the unlocking component 600 from being pulled out of the moving gap between the lower housing and the outer cover under the action of an external force, refer to Figures 10 - 12 As shown, in an embodiment of the present application, the unlocking component 600 further includes: a first limiting arm 604 and a second limiting arm 605.

[0096] The first limiting support arm 604 protrudes from the body 601, and the first limiting support arm 604 is located on one side of the accommodation through hole 6011. The first limiting support 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 body 601 into the first limiting groove, and the first limiting bending arm 6042 bends towards the first sub-bottom wall surface.

[0097] In some embodiments of the present application, the dimension of the first limiting support arm 604 along the length direction of the 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 support arm 604 can move along the length direction in the first limiting groove.

[0098] In some embodiments of the present application, the first limiting support arm 604 is arranged on one side of the accommodation through hole 6011. In this way, the first limiting support arm 604 can widen the body 601 on one side of the accommodation through hole 6011, thereby enhancing the strength of the body 601.

[0099] In some examples of the embodiments of the present application, a part of the first limiting support arm 604 can be bent downward towards the lower housing 202, so as to form the first limiting extension arm 6041 and the first limiting bending arm 6042; in this way, the dimension of the first limiting support arm 604 along the thickness direction of the body 601 can be increased. When limiting the unlocking component 600, the first limiting bending arm 6042 can block on the side wall of the first limiting groove facing away from the second wall surface, that is, the dimension of the first limiting support arm 604 along the thickness direction of the body 601 is greater than the gap between the first sub-recessed portion and the outer cover plate, so as to prevent the unlocking component 600 from being pulled through. In addition, increasing the dimension of the first limiting support arm 604 along the thickness direction of the body 601, in this way, when limiting the unlocking component 600, the stress area of the first limiting support arm 604 along the thickness direction of the body 601 is increased, improving the stability of the body 601 in the thickness direction; when the 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.

[0100] It can be understood that in the embodiments of the present application, the second limiting support arm 605 protrudes from the body 601, and the second limiting support arm 605 is located on the other side of the accommodation through hole 6011. The second limiting support arm 605 includes a second limiting extension arm 6051 and a second limiting bending arm 6052. The second limiting extension arm 6051 extends along the width direction of the body 601 into the second limiting groove, and the second limiting bending arm 6052 bends towards the second sub-bottom wall surface. In the embodiments of the present application, the setting manner of the second limiting support arm 605 can be the same as or similar to that of the first limiting support arm 604. For details, reference can be made to the detailed description of the first limiting support arm 604, and the embodiments of the present application will not elaborate on this.

[0101] In addition, in the embodiments of the present application, the first limiting arm 604 and the second limiting arm 605 can be symmetrically arranged with respect to the receiving through hole 6011; in this way, the unlocking component 600 can be stably limited by the symmetric first limiting arm 604 and the second limiting arm 605, avoiding the unlocking component 600 from shaking in the second recess.

[0102] In some embodiments of the present application, when the unlocking component 600 moves to the second preset position towards the first wall surface 2021, the first limiting arm 604 abuts against the wall surface on the side of the first limiting groove facing away from the second wall surface, and the second limiting arm 605 abuts against the wall surface on the side of the second limiting groove 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 situation that the unlocking component 600 moves excessively in the second recess, causing fatigue of the reset member 607, and effectively improving the service life of the reset member 607, that is, improving the effective unlocking times of the unlocking component 600.

[0103] In some examples of the embodiments of the present application, 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 in the width direction of the lower housing, and an avoidance notch 6032 is provided between the two unlocking arms 6031 for avoiding the locking portion. When the optical module and the host computer are in a locked state, the locking portion passes through the avoidance notch 6032, and the two unlocking arms 6031 are located on both sides of the locking portion.

[0104] In some examples, the force applying member 603 has a fourth bending portion 60311, and the fourth bending portion 60311 is bent from the end of the force applying member 603 facing away from the body 601 towards the second wall surface, and the fourth bending portion 60311 is attached to the side of the force applying member 603 facing the second wall surface. In some examples, the fourth bending portion 60311 can be formed by bending a part of the unlocking arm 6031 towards the second wall surface. In some embodiments of the present application, by providing the fourth bending portion 60311, the strength of the force applying member 603 can be improved, ensuring that the force applying member 603 will not be bent and deformed during the unlocking process, and ensuring the effectiveness of the unlocking component 600 to unlock 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.

[0105] Figure 13 Another structural schematic diagram of the unlocking component in the optical module provided according to the embodiments of the present application. Refer to Figure 13 As shown, in the embodiments of the present application, the unlocking component 600 further includes a rubber-coated handle 606, one end of the rubber-coated handle 606 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 recess, and the rubber-coated handle 606 is limited between the third limiting wall surface and the fourth limiting wall surface.

[0106] It can be understood that in the embodiments of the present application, a part of the overmolded handle 606 may be limited between the third limiting wall surface and the fourth limiting wall surface. Another part of the overmolded handle 606 extends to the side of the first wall surface facing away from the second wall surface. When it is necessary to pull out or extract the optical module from the host computer, the overmolded handle 606 can be pulled, so that the overmolded handle 606 drives the body 601, the pushing member 602 and the force applying member 603 of the unlocking component to move towards the first wall surface.

[0107] In some embodiments of the present application, since the overmolded handle 606 covers one end of the body 601 facing away from the second wall surface, the size of the overmolded handle 606 is slightly larger than the size of the body 601; the width dimension between the third limiting wall surface and the fourth limiting wall surface is set to be larger than the width dimension between the first limiting wall surface and the second limiting wall surface. In this way, the overmolded handle 606 can be in clearance fit with the third limiting wall surface and the fourth limiting wall surface, thereby reducing the friction force received by the overmolded handle 606 and improving the smoothness of the unlocking component 600 moving in the second recess.

[0108] Since the second bottom wall surface is recessed from the first bottom wall surface, during processing and production, the thickness of the second bottom wall surface is relatively thin and difficult to process. To avoid forming a relatively large through hole at the second bottom wall surface and prevent the overmolded handle 606 from entering the lower housing and interfering with the lower housing, resulting in the situation that the unlocking component 600 moves smoothly, in some examples of the embodiments of the present application, a fiber optic adapter mounting structure is provided in the lower housing, and the fiber optic adapter mounting structure is located on the side of the second bottom wall surface facing the first bottom wall surface, so that the side of the second bottom wall surface facing the first bottom wall surface is a closed bottom wall surface.

[0109] That is to say, in some embodiments of the present application, the part of the second bottom wall surface can be thickened by the fiber optic adapter mounting structure in the lower housing. When the second bottom wall surface is recessed from the first bottom wall surface, the part of the second bottom wall surface with the fiber optic 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, the situation of interference between the overmolded handle 606 and the lower housing can be avoided, and the smoothness of the unlocking component 600 moving in the second recess can be improved.

[0110] To facilitate the connection between an external optical fiber (such as an optical connector of the external optical fiber) and the fiber optic adapter of the optical port, in some examples of the embodiments of the present application, the overmolded handle 606 is a soft component. For example, the overmolded handle 606 can be made of silicone, soft plastic or soft rubber materials, etc. In this way, when the optical connector of the external optical fiber is inserted into the fiber optic adapter, the overmolded handle 606 can be bent, so as to facilitate the connection between the fiber optic adapter and the external optical fiber connector.

[0111] As an alternative example, a pull ring may be provided at one end of the rubber-coated handle 606 that extends to the lower housing facing away from the host computer. The pull ring may have a circular hole shape, an elliptical hole shape, or other special-shaped hole structures, and the embodiments of the present application do not limit this.

[0112] Figure 14 It is a cross-sectional view of the unlocking component in the optical module provided according to the embodiments of the present application. Figure 15 It is Figure 14 a partial enlarged view at position B in Figure 16 It is an exploded structural schematic diagram of the cooperation of the lower housing, the unlocking component, and the outer cover plate in the optical module provided according to the embodiments of the present application. Referring to Figures 14 - 16 As shown, in order to enhance the connection strength between the rubber-coated handle 606 and the body 601, increase the stress area of the rubber-coated handle 606, and change the stress direction of the rubber-coated handle 606 to avoid the situation where the rubber-coated handle 606 falls off or breaks from the body 601. In some embodiments of the present application, a plurality of notches 6013 are provided at one end of the body 601 facing away from the second wall surface. 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 application, the notches 6013 may be through holes, and in some examples, the notches 6013 may also be grooves. In some embodiments of the present application, the notches 6013 being through holes are taken as an example for illustration. Among them, a part of the rubber-coated handle 606 is embedded into the notches 6013. When specifically setting, it may be when the rubber-coated handle 606 is in a molten state (liquid state), it is injected into the mold where the body 601 is placed, and the liquid rubber fills into the notches 6013, and the parts on both sides of the body 601 are connected through the parts in the notches 6013 to form an integral part. In this way, after the rubber-coated handle 606 is connected to the body 601, the stress area and strength of the rubber-coated handle 606 are increased, the situation where the rubber-coated handle 606 is pulled off can be effectively avoided, and the acting force between the rubber-coated handle 606 and the body 601 is converted from the surface friction force to the tensile force in the notches 6013, which can enhance the acting force of the rubber-coated handle 606 on the main body part 601 and avoid the situation where the rubber-coated handle 606 falls off from the body 601.

[0113] In some embodiments of the present application, the thickness of the part of the rubber-coated handle 606 covering the body 601 is greater than the thickness of the end of the rubber-coated handle 606 facing away from the second wall surface. In this way, on the one hand, it can enhance the strength at the connection between the rubber-coated handle 606 and the body 601, and on the other hand, it can save the material used for the rubber-coated handle 606 and reduce the processing production cost.

[0114] Figure 17 It is a structural schematic diagram of the outer cover plate in the optical module provided according to the embodiments of the present application. Figure 18 It is another structural schematic diagram of the outer cover plate in the optical module provided according to the embodiments of the present application.Figure 19 Another structural schematic diagram of the outer cover plate in the optical module provided according to the embodiments of the present application, Figure 20 is Figure 19 a partial enlarged view of the position C in Figures 16 - 20 Referring to the figure shown, the outer cover plate 700 includes: a first protruding portion 701, a cover plate main body 702, and a first extension portion 703; wherein, the first protruding portion 701 includes: a first bending portion 7011 and a second bending portion 7012.

[0115] In some examples, the outer cover plate 700 can be made of a sheet metal part. Among them, the cover plate main body 702 can be covered on the first wall surface 2021 and is located on the side of the unlocking component facing away from the lower housing 202.

[0116] The first extension portion 703 can extend from one end of the cover plate main body 702 to the second wall surface. For example, the first extension portion 703 can be provided at one end of the cover plate main body 702 facing the second wall surface. In some examples, the first extension portion 703 and the cover plate main body 702 can be an integral part. For example, the sheet metal part can be cut and processed to form the first extension portion 703. Among them, the first bending portion 7011 can be bent from one end of the first extension portion 703 facing the second wall surface (i.e., the end facing away from the cover plate main body 702) towards the lower housing 202 (usually it can also be understood as bending towards the inner side of the cover plate main body 702); in some embodiments of the embodiments of the present application, the first bending portion 7011 fits on the inner wall surface of the first extension portion 703. In this way, the occupied space of the first bending portion 7011 can be reduced, which is convenient for the arrangement of the second bending portion 7012.

[0117] In some embodiments of the present application, the second bending portion 7012 is bent from the first bending portion 7011 towards the lower housing 202, and the second bending portion 7012 can serve as the first protruding portion 701.

[0118] That is to say, in some embodiments of the present application, the first protruding portion 701 and the outer cover plate 700 can be an integral structure, that is, the sheet metal part is cut and bent to form the first protruding portion 701. In this way, since the first protruding portion 701 is formed by bending the sheet metal part, the first protruding portion 701 has a certain elasticity, which can improve the smoothness of the reset of the unlocking component.

[0119] In the embodiments of the present application, the cover plate main body 702, the first extension portion 703, the first bending portion 7011, and the second bending portion 7012 are formed by cutting and bending the sheet metal part, and they are used to resist and support when the unlocking component is reset; in this way, it is convenient for the processing and forming of the first protruding portion 701, and effectively saves the processing production cost of the first protruding portion 701.

[0120] In some examples of the embodiments of the present application, the second bending portion 7012 includes a first sub-bending segment 70121 and a second sub-bending segment 70122. Among them, the first sub-bending segment 70121 is bent from the first bending portion 7011 towards the lower housing 202. That is to say, in the embodiments of the present application, 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 be bent in the direction towards the lower housing 202, so as to form the first sub-bending segment 70121. In the embodiments of the present application, the second sub-bending segment 70122 is bent from the first sub-bending segment 70121 away from the lower housing 202; that is to say, the end of the first sub-bending segment 70121 faces the lower housing, and the beginning of the second sub-bending segment 70122 also faces the lower housing, and the end of the second bending segment faces 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 segment 70121 and the second sub-bending segment 70122, and when the unlocking component moves towards the second wall surface 2022, the arc-shaped bending portion 70123 abuts against the pushing member.

[0121] In some embodiments of the present application, the second bending portion 7012 is set as two sub-bending segments. Among them, the first sub-bending segment 70121 is bent towards the lower housing, and the second sub-bending segment 70122 is bent away from the lower housing; in this way, an arc-shaped bending portion 70123 is formed at the connection between the first sub-bending segment 70121 and the second sub-bending segment 70122; by abutting against the pushing member through the arc-shaped bending portion 70123, in this way, the contact part between the first protruding portion 701 and the pushing member is smoother, which can effectively avoid the situation that the pushing member is scratched, and thus the smoothness of the reset of the unlocking component can be improved, and the situation that the unlocking component gets stuck is avoided.

[0122] In some examples of the embodiments of the present application, the width of the first extension portion 703 is smaller than the width of the cover plate main body 702, and the width of the second bending portion 7012 is smaller than the width of the first bending portion 7011. That is to say, in some embodiments of the present application, when forming the first extension portion 703 at one end of the cover plate main body 702 facing the second wall surface, 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 plate main body 702. In this way, it is convenient to bend the first extension portion 703 to form the first bending portion 7011; the stress during bending the first extension portion 703 can be reduced. In addition, when bending the first bending portion 7011 to form the second bending portion 7012, the side of the first bending portion 7011 can be cut and processed 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 bending to form the second bending portion 7012, the stress during bending the second bending portion 7012 can be reduced.

[0123] In addition, when the outer cover plate 700 is installed on the first wall surface, the cover plate main body 702 is embedded in the first sub-sunken portion, and the outer wall surface of the cover plate main body 702 is flush with the first wall surface. The first extension portion 703 is embedded in the second sub-sunken 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 sunken portion. Wherein, the side wall surface of the first extension portion 703 can be in contact with the side wall surface of the second sub-sunken portion, so that the second sub-sunken portion can be used to limit the first extension portion 703.

[0124] As an alternative example, the width of the second bending portion 7012 can be slightly smaller than the width of the second sunken portion. In this way, when the outer cover plate 700 is installed on the first wall surface, the second bending portion 7012 is embedded in the second sunken portion and is in clearance fit with the side wall surface of the second sunken portion, which facilitates the installation of the outer cover plate 700 and improves the installation efficiency of the outer cover plate 700.

[0125] In some embodiments of the present application, by providing a first sunken portion on the first wall surface and setting the first sunken portion to include a first sub-sunken portion and a second sub-sunken portion, in this way, the cover plate main body 702 can be embedded in the first sub-sunken portion, and the first extension portion 703 can be embedded in the second sub-sunken portion, so that the surface of the outer cover plate 700 can be flush with the first wall surface, and the overall flatness of the outer surface of the optical module can be maintained. In some embodiments of the present application, 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 in the width direction; referring to Figure 20 As shown, the first bending portion 7011 has a third side wall surface 70111 and a fourth side wall surface 70112. There is a first notch 70113 between the third side wall surface 70111 and the first side wall surface 70124, and a second notch 70114 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.

[0126] In some examples, after cutting the two side edges of the first bending portion 7011, a first notch 70113 can be formed by continuing to cut the first side wall surface 701244 of the second bending portion 7012 towards the first bending portion 7011. Among them, the processing and forming method of the second notch 70114 can be the same as or similar to that of the first notch 70113, and the embodiments of the present application will not elaborate on this.

[0127] In the embodiments of the present application, the width of the first extension portion 703 is set to be smaller than the width of the cover plate main body 702, the width of the second bending portion 7012 is set to be smaller than that of the first bending portion 7011, a first notch 70113 is provided 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 provided 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, the first notch 70113 and the second notch 70114 can release the stress generated by the bending of the second bending portion 7012, facilitating the bending and forming of the second bending portion 7012, and effectively protecting the first bending portion 7011 from being torn by the stress generated by the bending of the second bending portion 7012; that is, it facilitates the processing and forming of the first bending portion 7011 and the second bending portion 7012, ensuring the structural integrity of the outer cover plate 700.

[0128] In some examples of the embodiments of the present application, the outer cover plate 700 further includes a second extension portion 704 and a third bending portion 705. Among them, the second extension portion 704 is located at one end of the cover plate main 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 that of the cover plate main 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 bends from one end of the second extension portion 704 facing away from the second wall surface toward the lower housing, and the third bending portion 705 fits against the inner wall surface of the second extension portion 704; among them, 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 plate main 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 may refer to the dimension along the length direction of the lower housing. In some embodiments of the present application, the width of the third bending portion 705 is set to be greater than the width of the second extension portion 704, so that it is convenient to bend and form the third bending portion 705, improving the convenience of processing and production and the yield rate of the optical module product.

[0129] In some examples, the length dimension of the second extension portion 704 can be slightly smaller than the width between the third limiting wall surface and the fourth limiting wall surface; in this way, it is convenient for the second extension portion 704 to be embedded between the third limiting wall surface and the fourth limiting wall surface and limit the installation of the outer cover plate 700, for example, limit the outer cover plate 700 in the width direction along the lower housing.

[0130] In addition, in some embodiments of the present application, the second extension portion 704 can cover the side of the rubber-coated handle facing away from the lower housing, thereby limiting the rubber-coated handle, that is, in the embodiments of the present application, the second extension portion 704 can also play a certain limiting role in the direction of the rubber-coated handle facing away from the lower housing.

[0131] In addition, in some embodiments of the present application, a third bending portion 705 is formed by bending the end portion of the second extension portion 704. In this way, a bent arc is formed at the end portion of the second extension portion 704 facing away from the second wall surface, which can avoid the formation of burrs or rough edges at the end portion of the second extension portion 704. The end portion of the second extension portion 704 is arc-shaped, which can avoid scratching other components. In addition, when assembling an external optical fiber connector, the plastic-coated handle bends towards the second extension portion 704, which can also avoid scratching the plastic-coated handle, and can effectively extend the service life of the plastic-coated handle.

[0132] In some other examples of the embodiments of the present application, a recessed groove 7021 is formed by recessing the outer wall surface of the cover plate body 702. 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 application, the recessed groove 7021 can be obtained by stamping the cover plate body 702. In some examples, the recessed groove 7021 can also be obtained by cold rolling. The embodiments of the present application do not limit this. In some embodiments of the present application, the label can be pasted in the recessed groove 7021. Generally, the thickness of the label is 0.2 mm. In some embodiments of the present application, the depth of the recessed groove 7021 can be 0.4 mm - 0.5 mm. In this way, the label sinks into the recessed groove 7021, and during the transportation, transfer, movement or use of the optical module, the situation where the label is scraped off can be avoided, that is, the label can be protected.

[0133] In some examples of the embodiments of the present application, a second protruding portion 7022 is formed by protruding the inner wall surface of the cover plate body 702 corresponding to the recessed groove 7021, and the protruding height of the second protruding portion 7022 is greater than the thickness of the third bending portion 705. It can be understood that in some embodiments of the present application, when stamping the cover plate body 702 to form the recessed groove 7021, the second protruding portion 7022 is formed on the opposite side of the recessed groove 7021. In this way, the second protruding portion 7022 can enhance the strength of the cover plate body 702. When the unlocking component moves towards the first wall surface, due to the arrangement of the pushing member, the unlocking component moves simultaneously away from the lower housing (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 embodiments of the present application, by forming the second protruding portion 7022 on the inner wall of the outer cover plate 700, in this way, the second protruding portion 7022 abuts against the unlocking component, and the situation where the unlocking component pushes the outer cover plate 700 to deform can be avoided.

[0134] In some examples, the outer cover plate 700 further includes a third side plate 706 and a fourth side plate 707. A plurality of first buckles 7061 arranged side by side protrude from the inner surface of the third side plate 706, and a plurality of second buckles 7071 arranged side by side protrude from the inner surface of the fourth side plate 707. The third side plate 706 is embedded in the third recess, and the first buckles 7061 are clamped in the first card slots. The fourth side plate 707 is embedded in the fourth recess, and the second buckles 7071 are clamped in the second card slots.

[0135] In some embodiments of the present application, the first card slot may be formed by inward stamping of the side wall of the third recess. The first card slot may be provided with two, three, four, etc. In the embodiments of the present application, the number of the first card slots is not limited. Among them, the setting method of the second card slot may be the same as or similar to that of the first card slot, and details are not described herein again in the embodiments of the present application. In some examples, the second card slot may be symmetrically arranged with the first card slot. In this way, the positioning process when setting the first card slot and the second card slot can be reduced, and the processing efficiency can be improved.

[0136] Correspondingly, the first buckle 7061 may also be formed by stamping the third side plate 706, and the number of the first buckles 7061 may be the same as the number of the first card slots. In addition, the setting method of the second buckle 7071 may also be the same as or similar to that of the first buckle 7061, and details are not described herein again in the embodiments of the present application.

[0137] In some embodiments of the present application, when assembling the outer cover plate 700, the third side plate 706 can be inserted into the third recess, the fourth side plate 707 can be inserted into the fourth recess, and the first buckle 7061 can be snapped into the first card slot, and the second buckle 7071 can be snapped into the second card slot, which improves the installation and assembly efficiency of the outer cover plate 700.

[0138] In some examples, the wall surface of the third side plate 706 contacts the wall surface of the third recess, and the wall surface of the fourth side plate 707 contacts the wall surface of the fourth recess, thereby forming a limit on the outer cover plate 700 and improving the stability of the installation of the outer cover plate 700.

[0139] In other examples, the thickness of the third side plate 706 is the same as or approximately the same as the depth of the third recess, so that when the third side plate 706 is inserted into the third recess, the outer wall surface of the third side plate 706 is flush with the outer wall surface of the first side plate. Correspondingly, the thickness of the fourth side plate 707 is the same as or approximately the same as the depth of the fourth recess, so that when the fourth side plate 707 is inserted into the fourth recess, the outer wall surface of the fourth side plate 707 is flush with the outer wall surface of the second side plate, improving the flatness of the surface of the optical module.

[0140] Figure 21 It is a cross-sectional view of the cooperation between the unlocking component and the lower housing in the optical module provided by the embodiment of the present application. Figure 22 It isFigure 21 Partial enlarged view at D in Figure 23 Partial enlarged view when the unlocking component in the optical module provided according to the embodiment of the present application moves to a preset position Figure 24 Another cross-sectional view of the cooperation between the unlocking component and the lower housing in the optical module provided according to the embodiment of the present application Figure 25 For Figure 24 Partial enlarged view at E in Figures 21 - 25 As shown, in some examples of the embodiment of the present application, when it is necessary to pull out or extract the optical module from the host computer, the unlocking component can be moved in the direction of the first wall surface 2021. For example, referring to Figure 21 As shown, the unlocking component 600 can move along Figure 21 The negative x-axis direction in

[0141] In some embodiments of the present application, the first wall surface 2021 protrudes from the second wall surface 2022. When the pushing member 602 moves from the second wall surface 2022 to the first wall surface 2021, the step formed between the first wall surface 2021 and the second wall surface 2022 (such as the pushing wall surface 2152 described in detail in the foregoing embodiments of the present application) abuts against the surface of the pushing member 602 facing the lower housing 202; thus, the pushing member 602 will be subjected to the acting force of the pushing member 602, so as to lift the height of the pushing member 602. At this time, the entire unlocking component 6 moves away from the lower housing 202 under the drive of the pushing member 602. For example, referring to Figure 21 As shown, the entire unlocking component 600 moves in the direction shown by the positive y-axis in 21. For example, it moves from the state shown in Figure 21 Shown in Figure 25 Shown in

[0142] In some embodiments of the present application, the force - applying member 603 is connected to one end of the pushing member 602 facing the locking portion. In some embodiments of the present application, the force - applying member 603 can be parallel or approximately parallel to the second wall surface 2022. It can be understood that when the unlocking component moves towards the first wall surface 2021, due to the interaction between the pushing member 602 and the pushing wall surface 2152 between the first wall surface 2021 and the second wall surface 2022, the entire unlocking component moves away from the lower housing 202 under the drive of the pushing member 602; at this time, the force - applying member 603 moves away from the second wall surface 2022, thereby pushing the locking spring piece on the upper computer cage away from the locking portion 20221, realizing the unlocking of the optical module and the upper computer.

[0143] In some alternative examples of the embodiments of the present application, due to the arrangement of the pushing member 602, when the unlocking component 600 moves towards the first wall surface 2021, the entire unlocking component 600 is pushed by the pushing member 602 and moves away from the lower housing; 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 surface 2022, in some embodiments of the present application, a first protruding portion 701 is provided on one side of the outer cover plate 700 facing the pushing member 602; when the unlocking component 600 moves towards the second wall surface to the first preset position (for example, when it reaches the position shown in Figure 23 ), the first protruding portion 701 contacts the pushing member 602, so that the unlocking component 600 moves towards the lower housing, and when the unlocking component 600 is in the reset state, the first protruding portion 701 has an interference fit with the unlocking component 600.

[0144] That is to say, in some embodiments of the present application, after the unlocking component 600 unlocks the optical module and the upper computer, during the process of the unlocking component 600 moving back to the second wall surface 2022 for reset, the unlocking component 600 first moves along the length direction of the first wall surface 2021 or the second wall surface 2022; when the unlocking component 600 moves to the first preset position, the pushing member 602 contacts the first protruding portion 701. Since the pushing member 602 is inclined, the force exerted by the first protruding portion 701 on the pushing member 602 can be decomposed into a force perpendicular to the lower housing 202 and a force along the length direction of the lower housing 202; at this time, under the action of the reset force, the unlocking component 600 continues to move along the length direction of the lower housing 202, and the force exerted by the first protruding portion 701 on the pushing member 602 pushes the entire unlocking component 600 towards the lower housing 202, so that the force - applying member 603 fits on the second wall surface 2022.

[0145] In some examples, the first protruding portion 701 may be a rib, a bead or an elastic piece provided on the inner wall of the outer cover plate 700. The first protruding portion 701 may extend along the width direction of the outer cover plate 700; wherein, the length of the first protruding portion 701 may match the width of the unlocking member. For example, the length of the first protruding portion 701 may be the same as, similar to or approximate to the width of the unlocking member.

[0146] In some possible examples, when the unlocking member is in the reset state, the first protruding portion 701 may abut against the top of the pushing member facing away from the connection with the main body 601. In this way, when the unlocking member is in the reset state, the first protruding portion 701 and the unlocking member may be in an interference fit state, so that the force applying member 603 is completely attached to the second wall surface.

[0147] The optical module provided by the embodiment of the present application forms a receiving cavity by covering the upper housing and the lower housing, and arranges the circuit board and the optical transceiver component in the receiving cavity, which facilitates 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 housing, the second wall surface is recessed from 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 host computer, the locking portion on the second wall surface establishes a locking relationship with the outside, for example, locks with the locking structure on the host computer cage; in the embodiment of the present application, the body of the unlocking component is arranged on the first wall surface, the pushing member of the unlocking component is inclined 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 it is necessary to pull out the optical module from the host 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 whole unlocking component to move away from the lower housing, so that the force applying member pushes the locking structure on the host computer cage away from the locking portion, thereby unlocking the locking portion; in addition, an outer cover plate is covered on the first wall surface, and the outer cover plate is covered on the side of the unlocking component facing away from the lower housing. In this way, the outer cover plate limits the unlocking component on the lower housing and allows it to move along the length direction of the lower housing. There is a moving gap for the unlocking component between the outer cover plate and the lower housing, which facilitates the pushing member to move from the second wall surface to the first wall surface when the unlocking component moves towards the first wall surface, so as to push the whole unlocking component in the direction away from the lower housing, that is, it is convenient for the force applying member to apply a force to the locking structure of the host computer cage; in the embodiment of the present application, a first protrusion is arranged on the side of the outer cover plate facing the pushing member. During the process of the unlocking component moving back to the second wall surface to reset, the first protrusion can selectively abut against the pushing member. In this way, the first protrusion has a force facing the lower housing on the pushing member, so that the unlocking component moves towards the lower housing while moving back to the second wall surface, so that the force applying member can move while adhering to the second wall surface during the reset process of the unlocking component from the first preset position, which is convenient for the force applying member to be inserted under the locking structure of the host computer cage, facilitates the normal reset of the unlocking component, and can be smoothly unlocked during the next unlocking, improving the smoothness and stability of the unlocking of the unlocking component.

[0148] In some examples of the embodiment of the present application, when the unlocking component moves towards the first wall surface to the first preset position (for example, as shown in Figure 22 the first preset position may be the position where the pushing member 602 starts to contact the pushing wall surface 2152), the pushing member 602 is separated from the first protrusion 701. When the unlocking component continues to move towards the first wall surface, there is a certain gap between the pushing member 602 and the first protrusion 701. That is to say, in some embodiments of the present application, when the unlocking component moves towards the first wall surface to the first preset position, the acting force between the first protrusion 701 and the pushing member 602 is zero. After the unlocking component continues to move a certain distance to reach the unlocking position, the force applying member 603 completely unlocks the optical module from the host computer.

[0149] When the unlocking component moves to the first preset position towards the second wall surface, the first protruding portion 701 contacts the pushing member 602, so that the unlocking component 600 moves towards the lower housing. And when the unlocking component is in the reset state, the vertical distance between the first protruding portion 701 and the second wall surface is less than the vertical distance between the surface of the main body 601 facing away from the second wall surface and the second wall surface.

[0150] That is to say, when the unlocking component 600 is in the reset state, at least one of the first protruding portion 701 and the unlocking component can undergo a certain deformation. For example, the first protruding portion 701 may have a certain deformation facing away from the lower housing. 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 protruding portion 701 and the unlocking component may undergo a certain deformation.

[0151] In the embodiment of the present application, the pushing member 602 is arranged to be separated from the first protruding portion 701 when the unlocking component moves to the first preset position towards the first wall surface, and when the unlocking component moves to the first preset position towards the second wall surface, the first protruding portion 701 contacts the pushing member 602, so that the unlocking component moves towards the lower housing. And when the unlocking component is in the reset state, the vertical distance between the first protruding portion 701 and the second wall surface is less than the vertical distance between the surface of the main body 601 facing away from the second wall surface and the second wall surface. In this way, during the process of the optical module being in the locked state or the unlocking component being in the reset state, the unlocking component 600 can receive the pressing force provided by the first protruding portion 701 pointing to the lower housing, so that the unlocking component fits with the lower housing, which is convenient for the optical module and the host computer to be stably locked.
