Technical Field

[0002] The present disclosure relates to the field of communication technology, and in particular to an optical module. Background Art

[0003] Optical modules consist of optoelectronic components, functional circuits, and optical interfaces, performing optical-to-electrical and electro-optical conversion. Optical modules are categorized by package type, primarily including SFP (Small Form-Factor Pluggable), GBIC (Gigabit Interface Converter), and XFP (10Gigabit Small Form Factor Pluggable). SFP optical modules are hot-swappable, small-form-factor optical modules packaged as SFP. Because SFP optical modules require frequent insertion and removal from a host computer during use, they are equipped with a release mechanism to facilitate insertion and removal from the host computer. Currently, the release ring of an SFP optical module applies force in the direction of removal, resulting in a long linear travel distance between the ring and the module, which can easily interfere with other components within some devices. Therefore, the current release mechanism of SFP optical modules is not suitable for some devices. Summary of the Invention

[0050] Some embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. However, the embodiments described are only some of the embodiments of the present disclosure, not all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments provided in the present disclosure are within the scope of protection of the present disclosure.

[0051] Unless the context requires otherwise, throughout the specification and claims, the term "including" is to be interpreted as open and inclusive, that is, "including, but not limited to"; the terms "first" and "second" are not to be understood as indicating or implying relative importance or indicating an upper limit on quantity; the term "plurality" means two or more; the term "connected" is to be understood in a broad sense, for example, "connected" can be a fixed connection, a detachable connection, or an integral connection, and can be directly connected or indirectly connected through an intermediate medium; the use of the terms "suitable for" or "configured to" means open and inclusive language, which does not exclude equipment that is suitable for or configured to perform additional tasks or steps; terms such as "parallel", "perpendicular", "same", "consistent", "level" and so on are not limited to absolute mathematical theoretical relationships, but also include acceptable error ranges generated in practice, and also include differences based on the same design concept but due to manufacturing reasons.

[0052] In optical communication technology, to establish information transmission between information processing devices, it is necessary to load the information onto light and use the propagation of light to achieve information transmission. Here, the light loaded with information is an optical signal. When transmitting optical signals within information transmission equipment, they can reduce optical power loss, thereby enabling high-speed, long-distance, and low-cost information transmission. The signals that information processing equipment can recognize and process are electrical signals. Information processing equipment typically includes optical network units (ONUs), gateways, routers, switches, mobile phones, computers, servers, tablets, televisions, etc., and information transmission equipment typically includes optical fibers and optical waveguides.

[0053] Optical modules can convert optical signals into electrical signals between information processing devices and information transmission devices. For example, at least one of the optical signal input or output ends of an optical module is connected to an optical fiber, and at least one of the electrical signal input or output ends of the optical module is connected to an optical network terminal. A first optical signal from the optical fiber is transmitted to the optical module, which converts the first optical signal into a first electrical signal and transmits the first electrical signal to the optical network terminal. A second electrical signal from the optical network terminal is transmitted to the optical module, which converts the second electrical signal into a second optical signal and transmits the second optical signal to the optical fiber. Because multiple information processing devices can transmit information via electrical signals, at least one of the multiple information processing devices needs to be directly connected to the optical module, rather than all of them. Here, the information processing device directly connected to the optical module is referred to as the optical module's host computer. Furthermore, the optical signal input or output end of the optical module can be referred to as an optical port, and the electrical signal input or output end of the optical module can be referred to as an electrical port.

[0054] FIG1 is a partial structural diagram of an optical communication system according to some embodiments. As shown in FIG1 , the optical communication system mainly includes a remote information processing device 1000 , a local information processing device 2000 , a host computer 100 , an optical module 200 , an optical fiber 101 , and a network cable 103 .

[0055] One end of optical fiber 101 extends toward remote information processing device 1000, and the other end of optical fiber 101 is connected to optical module 200 through the optical port of optical module 200. Optical signals can be totally reflected in optical fiber 101, and the propagation of the optical signal in the direction of total reflection can almost maintain the original optical power. The optical signal undergoes multiple total reflections in optical fiber 101 to transmit the optical signal from remote information processing device 1000 to optical module 200, and vice versa, thereby achieving long-distance, low-power information transmission.

[0056] The optical communication system may include one or more optical fibers 101, and the optical fibers 101 may be detachably connected or fixedly connected to the optical module 200. The host computer 100 is configured to provide data signals to the optical module 200, receive data signals from the optical module 200, or monitor or control the operating status of the optical module 200.

[0057] The host computer 100 includes a substantially rectangular housing and an optical module interface 102 disposed on the housing. The optical module interface 102 is configured to connect to the optical module 200 to establish a unidirectional or bidirectional electrical signal connection between the host computer 100 and the optical module 200.

[0058] The host computer 100 also includes an external electrical interface that can access an electrical signal network. For example, the external electrical 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 that an electrical signal connection is established between the local information processing device 2000 and the host computer 100 via the network cable 103. For example, a third electrical signal emitted by the local information processing device 2000 is transmitted to the host computer 100 via the network cable 103. The host computer 100 generates a second electrical signal based on 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 optical fiber 101. The second optical signal is transmitted to the remote server 1000 via the optical fiber 101. For example, a first optical signal from the remote information processing device 1000 is transmitted through the optical fiber 101. The first optical signal from the 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 based on the first electrical signal and transmits the fourth electrical signal to the local information processing device 2000. It should be noted that optical modules are tools for converting optical signals into electrical signals. During this conversion process, the information does not change, but the encoding and decoding methods of the information can change.

[0059] In addition to the optical network terminal, the host computer 100 also includes an optical line terminal (OLT), an optical network device (ONT), or a data center server.

[0060] Figure 2 is a partial structural diagram of a host computer according to some embodiments. To clearly illustrate the connection between the optical module 200 and the host computer 100, Figure 2 only shows the structure of the host computer 100 related to the optical module 200. As shown in Figure 2, the host computer 100 also includes a PCB circuit board 105 disposed within the housing, a cage 106 disposed on the surface of the PCB circuit board 105, a heat sink 107 disposed on the cage 106, and an electrical connector disposed within the cage 106. The electrical connector is configured to connect to the electrical port of the optical module 200; the heat sink 107 has raised structures such as fins to increase the heat dissipation area.

[0061] The optical module 200 is inserted into the cage 106 of the host computer 100. The cage 106 secures the optical module 200. Heat generated by the optical module 200 is transferred to the cage 106 and then dissipated through the heat sink 107. After the optical module 200 is inserted into the cage 106, the electrical port of the optical module 200 connects with the electrical connector inside the cage 106, thereby establishing a bidirectional electrical signal connection between the optical module 200 and the host computer 100. Furthermore, the optical port of the optical module 200 connects to the optical fiber 101, thereby establishing a bidirectional optical signal connection between the optical module 200 and the optical fiber 101.

[0062] Figure 3 is a structural diagram of an optical module according to some embodiments, Figure 4a is an exploded view of an optical module according to some embodiments, and Figure 4b is an exploded view of an optical module according to some embodiments. As shown in Figures 3 to 4b, the optical module 200 includes a housing, a circuit board 300 disposed within the housing, a light emitting component 400, and a light receiving component 500. However, the present disclosure is not limited to this. In some embodiments, the optical module 200 includes either the light emitting component 400 or the light receiving component 500.

[0063] The housing includes an upper housing 201 and a lower housing 202 . The upper housing 201 covers the lower housing 202 to form the housing having two openings 204 and 205 . The outer contour of the housing is generally a square.

[0064] In some embodiments, the lower shell 202 includes a base plate 2021 and two lower side plates 2022 located on both sides of the base plate 2021 and arranged perpendicular to the base plate 2021; the upper shell 201 includes a cover plate 2011, and the cover plate 2011 covers the two lower side plates 2022 of the lower shell 202 to form the above-mentioned shell.

[0065] In some examples, a support plate 2016 is provided at the optical port of the upper housing 201, and the support plate 2016 is located on the opposite side of the cover plate 2011. The support plate 2016 has a housing gap 2015 to facilitate marking the direction of the optical module and avoid errors when inserting external optical fibers into the optical port.

[0066] In some embodiments, the support plate 2016 may be located in the lower shell, which is not specifically limited here.

[0067] In some embodiments, the lower shell 202 includes a base plate 2021 and two lower side plates 2022 located on both sides of the base plate 2021 and arranged perpendicularly to the base plate 2021; the upper shell 201 includes a cover plate 2011 and two upper side plates located on both sides of the cover plate 2011 and arranged perpendicularly to the cover plate 2011. The two upper side plates are combined with the two lower side plates 2022 to achieve the upper shell 201 covering the lower shell 202.

[0068] In some embodiments, the upper housing 201 includes a cover plate 2011, and a first upper side plate 20121 and a second upper side plate 20122 located on both sides of the cover plate 2011 and arranged perpendicular to the cover plate 2011. The first upper side plate 20121 and the second upper side plate 20122 extend from one end of the cover plate 2011 to the other end of the cover plate 2011.

[0069] The direction of the line connecting the two openings 204 and 205 can be consistent with the length direction of the optical module 200, or it can be inconsistent with the length direction of the optical module 200. For example, opening 204 is located at the end of the optical module 200 (the right end in Figure 3), and opening 205 is also located at the end of the optical module 200 (the left end in Figure 3). Alternatively, opening 204 is located at the end of the optical module 200, while opening 205 is located on the side of the optical module 200. Opening 204 is an electrical port, and the gold finger of the circuit board extends from the electrical port 204 and is inserted into the electrical connector of the host computer 100; opening 205 is an optical port, which is configured to connect to the external optical fiber 101, so that the optical fiber 101 connects the light emitting component 400 and the light receiving component 500 in the optical module 200.

[0070] In some examples, a support plate 2016 is provided at the optical port of the upper housing 201, and the support plate 2016 is located on the opposite side of the cover plate 2011. The support plate 2016 has a housing gap 2015 to facilitate marking the direction of the optical module and avoid errors when inserting external optical fibers into the optical port.

[0071] The combined assembly of the upper housing 201 and the lower housing 202 facilitates installation of the circuit board, light emitting component 400, light receiving component 500, and the like within the housing, which then encapsulates and protects these components. Furthermore, during assembly of the circuit board, light emitting component 400, and light receiving component 500, the positioning components, heat dissipation components, and electromagnetic shielding components of these components are easily positioned, facilitating automated production.

[0072] In some embodiments, the upper shell 201 and the lower shell 202 are made of metal materials, which facilitates electromagnetic shielding and heat dissipation.

[0073] In some embodiments, the optical module 200 further includes an unlocking component 600 located outside its housing. The unlocking component 600 is configured to achieve a fixed connection between the optical module 200 and the host computer, or to release the fixed connection between the optical module 200 and the host computer.

[0074] For example, the unlocking component 600 is located on the outside of the two lower side panels 2022 of the lower housing 202 and includes a snap-fit ​​component that mates with the cage 106 of the host computer 100. When the optical module 200 is inserted into the cage 106, the snap-fit ​​component of the unlocking component 600 secures the optical module 200 in the cage 106. When the unlocking component 600 is pulled, the snap-fit ​​component of the unlocking component 600 moves accordingly, thereby changing the connection between the snap-fit ​​component and the host computer, thereby releasing the optical module 200 from the cage 106 and allowing the optical module 200 to be removed from the cage 106.

[0075] Figure 5 is a partial schematic diagram of the connection between an unlocking component and an upper housing, according to some embodiments. Figure 6a is a partial exploded schematic diagram of an unlocking component and an upper housing, according to some embodiments. As shown in Figures 5 and 6a, the cover plate 2011 of the upper housing 201 is provided with a mating protrusion 2013, which engages with a corresponding component on the cage. When the optical module 200 is inserted into the cage 106, the mating protrusion 2013 secures the optical module 200 in the cage 106. The upper housing 201 is provided with a clamping shaft and a mounting seat 220. The unlocking component 600 includes a pull ring 610 and an unlocking member 620.

[0076] In some embodiments, the pull ring 610 and the unlocking member 620 may be assembled and connected to the housing. The pull ring 610 can rotate on the housing. When the pull ring 610 rotates, it pushes the unlocking member 620. When the unlocking member 620 is pushed, it changes the connection between the mating protrusion 2013 and the cage 106, thereby releasing the fixed relationship between the optical module 200 and the cage 106, thereby allowing the optical module 200 to be removed from the cage 106. For example, the pull ring 610 may be assembled and connected to the upper housing 201, and the unlocking member 620 may be assembled and connected to the upper housing 201. Of course, in some embodiments, the pull ring 610 or the unlocking member 620 may be assembled and connected to the lower housing 202.

[0077] In some embodiments, a latching shaft 210 is formed on the upper housing 201. The latching shaft 210 is assembled and connected to the pull ring 610, allowing the pull ring 610 to rotate on the upper housing 201. For example, a latching shaft 210 is formed on the outer side of one end of the first upper side plate 20121 and the outer side of one end of the second upper side plate 20122. Axial holes are formed on both sides of the pull ring 610. The axial holes on both sides of the pull ring 610 respectively assemble and connect the latching shafts 210 on the first upper side plate 20121 and the second upper side plate 20122. When the pull ring 610 is pulled, the pull ring 610 rotates around the latching shaft 210.

[0078] In some embodiments, a mounting base 220 is formed on the upper housing 201 and is located on the side of the matching protrusion 2013 near the optical port. The mounting base 220 is assembled and connected to an unlocking member 620, which is movable relative to the mounting base 220. The pull ring 610 rotates to push the unlocking member 620 to move on the mounting base 220. The unlocking member 620 is assembled and connected to the mounting base 220, and the unlocking member 620 has a locked position and an unlocked position during movement relative to the mounting base. For example, when the unlocking member 620 is in the locked position, the matching protrusion 2013 engages with a mating buckle on the cage 106, securing the optical module 200 to the cage 106 and preventing the entire optical module 200 from being removed from the cage. When the unlocking member moves to the unlocking position, the unlocking member 620 can drive the end of the mating buckle to lift up, so that the mating buckle moves along the surface of the matching protrusion and separates from the matching protrusion 2013, thereby releasing the buckling relationship between the matching protrusion 2013 and the cage 106, thereby allowing the optical module 200 to be separated from the cage 106, thereby enabling the optical module 200 to be pulled out of the cage.

[0079] In some embodiments, the pull ring 610 is disposed on the outer wall of one end of the housing formed by the upper and lower housings. The pull ring 610 is provided with an axial hole, and the locking shaft is mounted within the axial hole. When the pull ring is pulled from the electrical port toward the optical port, the pull ring 610 rotates along the locking shaft. The unlocking member 620 is movably disposed within the mounting seat 220 and has a locked position and an unlocked position during movement relative to the mounting seat 220. Specifically, when the unlocking member 620 is in the locked position, the mating protrusion 2013 engages with the mating buckle on the cage, locking the optical module in the cage and preventing removal of the entire optical module. When the unlocking member 620 is in the unlocked position, the unlocking member 620 drives the end of the mating buckle to lift, causing the mating buckle to move along the surface of the mating protrusion 2013 and separate from the mating protrusion 2013, thereby releasing the locking relationship and allowing the optical module to be separated from the cage, thereby unlocking the optical module.

[0080] In some embodiments, to better enable the mating protrusion 2013 to fit within the mating buckle, a snap groove 2014 is provided on the surface of the cover 2011. The surface of the snap groove 2014 is recessed relative to the surface of the cover 2011, toward the lower housing. The mating protrusion 2013 is positioned within the snap groove 2014, such that the bottom of the snap groove 2014 is lower than the surface of the cover 2011. The profile area of ​​the mating buckle is smaller than the bottom area of ​​the snap groove 2014. When the unlocking member 620 is in the locked position, the mating buckle is completely positioned within the snap groove 2014.

[0081] In some embodiments, the mating protrusion 2013 is a triangular protrusion structure that can be snapped into place with the annular mating buckle on the cage to fix the position of the optical module relative to the cage, ensuring stable operation of the optical module. From left to right, the height of the mating protrusion 2013 gradually decreases to reduce friction between the mating buckle and the mating protrusion during movement from right to left, thereby preventing the mating buckle from abutting against the step caused by the different heights.

[0082] In some embodiments, the triangular protrusion, from left to right, is shaped like an inverted triangle, with one corner of the triangular protrusion pointing toward the electrical port. The shape of the mating buckle matches the shape of the triangular protrusion. The corners of the triangular protrusion are chamfered in an arc shape, making the connection between the triangular protrusion and the mating buckle smoother and reducing friction between the mating buckle and the mating protrusion.

[0083] FIG6 b is a second partial schematic diagram of an exploded view of an unlocking component and an upper housing according to some embodiments. As shown in FIG6 b , in some embodiments, the unlocking component 600 may include an elastic member 630. The elastic member 630 is assembled and connected to the unlocking component 620 and the mounting base 220. When the pull ring 610 pushes the unlocking component 620 to move toward the unlocked position, the elastic member 630 is squeezed and deformed. When the force of rotating the pull ring 610 decreases, the elastic member 630 recovers its shape, generating a force that can push the unlocking component 620, causing the unlocking component 620 to move toward the locked position. For example, the elastic member 630 may be an elastic member such as a spring that can generate a recoverable deformation.

[0084] In some embodiments, the unlocking member 600 may include a first elastic member 631 and a second elastic member 632. The first elastic member 631 is located on one side of the unlocking member 620, and the second elastic member 632 is located on the other side of the unlocking member 620.

[0085] Figure 7a is a schematic diagram of an exploded view of a pull ring provided according to some embodiments. Figure 7b is a schematic diagram of a pull ring provided according to some embodiments from a second angle. Figures 7a and 7b show the pull ring from different angles. As shown in Figures 7a and 7b, the pull ring 610 includes a pull ring body 611 and a pull ring kit 612. The pull ring body 611 is a sealed or semi-sealed annular structure. The pull ring kit 612 is mounted on a side arm of the pull ring body 311. The type of optical module can be distinguished by setting an identification on the pull ring kit 612. For example, the identification set on the pull ring kit 612 can be distinguished by color or letter.

[0086] The pull ring body 611 includes: a first arm 6111, a second arm 6112, a third arm 6113, and a fourth arm 6114, which are connected end to end, and a bent portion 6115 located on the first arm 6111. For example, the side edge of the top of the second arm 6112 is connected to one end of the first arm 6111, and the side edge of the top of the fourth arm 6114 is connected to the other end of the first arm 6111, so that the first arm 6111 is suspended outside the second arm 6112 and the fourth arm 6114.

[0087] In order to reduce the space occupied by the optical module and enhance the strength of the pull ring body 611 , the width of each arm of the pull ring body 611 is greater than its thickness.

[0088] In some embodiments, the first arm 6111 is disposed opposite the third arm 6113, and the second arm 6112 is disposed opposite the fourth arm 6114. When the unlocking member is in the unlocked position, to reduce the space occupied by the optical module, the second arm 6112 and the fourth arm 6114 are located on the outer walls of the two side panels of the upper housing. For example, the second arm 6112 is located on the outer side of the first upper side panel 20121, the fourth arm 6114 is located on the outer side of the second upper side panel 20122, and the first arm 6111 is located at one end of the cover panel 2011.

[0089] In some embodiments, the first arm 6111 is located at the optical port, and the width of the first arm 6111 is distributed along the vertical direction of the optical module. The third arm 6113 is located on the outer wall of the support plate 2016. In some embodiments, the first arm 6111 and the third arm are arranged perpendicularly, and the third arm 6113 is located on the outer wall of the support plate 2016, thereby reducing the space occupied by the optical module in the left and right directions.

[0090] The bent portion 6115 is located on the sidewall of the first arm 6111 and between the second arm 6112 and the fourth arm 6114. The second and fourth arms protect the bent portion 6115. The lower surface of the bent portion 6115 is higher than the lower surface of the first arm 6111, positioning the bent portion 6115 above the cover. A gap exists between the lower surface of the bent portion 6115 and the upper surface of the cover.

[0091] The second arm 6112 has a first axial hole 6117, and the fourth arm 6114 has a second axial hole 6118. The center lines of the first axial hole 6117 and the second axial hole 6118 are flush with the surface of the cover 3011, so that the pull ring 610 can maintain balance during rotation and reduce the friction between the pull ring 610 and the surface of the upper shell 201.

[0092] In some embodiments, the bent portion 6115 includes a curved component 61151 and a reinforcing component 61152. The curved component 61151 is located between the first arm 6111 and the reinforcing component 61152 and has an arcuate shape. When the unlocking member is in the locked position, the reinforcing component 61152 is attached to the optical port, and the left end of the unlocking member 620 contacts the reinforcing component 61152. The reinforcing component 61152 is perpendicular to the cover plate 2011. The first arm 6111 is located to the left of the reinforcing component 61152. The reinforcing component is parallel to the first arm.

[0093] In some embodiments, both the first arm 6111 and the reinforcement component 61152 are plate-like structures, and a gap may be provided between the first arm 6111 and the reinforcement component 61152. To increase the strength of the pull ring and prevent deformation during unlocking, the gap between the first arm 6111 and the reinforcement component 61152 may be filled with reinforcing material.

[0094] During unlocking, the pull ring is pulled upward and to the left, causing the first arm 6111 and the bent portion 6115 to move downward and to the right around the axis of rotation. The contact point between the pull ring 610 and the unlocking member 620 gradually shifts from the reinforcing member 61152 to the curved member 61151, pushing the unlocking member 620 to the right. The curved member 61151 makes the unlocking process smoother and reduces jamming.

[0095] When the unlocking member is in the unlocked position, the reinforcement component 61152 is arranged parallel to the cover plate 2011, and the first arm 6111 is located above the reinforcement component 61152. In some embodiments, the third arm 6113 can be a single piece of sheet material or formed from two sheets of sheet material. As shown in FIG7 a , the third arm 6113 is formed from two sheets of sheet material and has an arm gap 6116. The pull ring assembly 612 is mounted on the surface of the third arm 6113, covering the arm gap 6116.

[0096] In some embodiments, the width of the arm gap 6116 is smaller than the width of the housing gap 2015, and the pull ring assembly 612 covers the arm gap 6116, and the pull ring assembly 612 also covers the housing gap 2015. In some embodiments, a first chamfer 614 is provided at the upper right corner of the second arm 6112. The first chamfer is arc-shaped, so that when the pull ring is pulled upward and left, the sliding between the second arm 6112 and the cover plate is smoother, reducing jamming.

[0097] In some embodiments, a second chamfer 613 is provided at the upper right corner of the fourth arm 6114, and the third chamfer is arc-shaped, so that when the pull ring is pulled to the upper left, the sliding between the fourth arm 6114 and the cover plate is smoother, reducing jamming.

[0098] Figure 8a is a first structural diagram of another pull ring according to some embodiments, and Figure 8b is a second structural diagram of another pull ring according to some embodiments. As shown in Figures 8a and 8b , in some embodiments, the pull ring 610 may include a first connecting portion 613 and a second connecting portion 614. The bottom of the first connecting portion 613 is connected to the top of the second support arm 6112, and the top side of the first connecting portion 613 is connected to one end of the first support arm 6111. The bottom of the second connecting portion 614 is connected to the top of the fourth support arm 6114, and the top side of the second connecting portion 614 is connected to the other end of the first support arm 6111.

[0099] In some embodiments, a first driving surface 6131 is formed on the other side of the first connecting portion 613. The bottom of the first driving surface 6131 contacts one end of the driving member 620. For example, the first driving surface 6131 is an arcuate surface. When the pull ring 610 rotates, the first driving surface 6131 rotates, pushing the unlocking member 620. As the first driving surface 6131 rotates, the contact position between the first driving surface 6131 and the unlocking member 620 continuously changes. When the unlocking member 620 is in the unlocked position, the top of the first driving surface 6131 contacts one end of the driving member 620.

[0100] In some embodiments, a second driving surface 6141 is formed on the other side of the second connecting portion 614. The bottom of the second driving surface 6141 contacts one end of the driving member 620. Exemplarily, the second driving surface 6141 is an arcuate surface. When the pull ring 610 rotates, the second driving surface 6141 rotates, pushing the unlocking member 620. As the second driving surface 6141 rotates, the contact position between the second driving surface 6141 and the unlocking member 620 continuously changes. When the unlocking member 620 is in the unlocked position, the top of the second driving surface 6141 contacts one end of the unlocking member 620.

[0101] Figure 9a is a schematic diagram of the first angle of a release member according to some embodiments. Figure 9b is a schematic diagram of the second angle of a release member according to some embodiments. Figures 9a and 9b illustrate the release member from different angles. As shown in Figures 9a and 9b, the release member 620 includes an release body 621, an release guide, and a spring compression portion. The first end of the release body 621 contacts and connects with the pull ring, while the second end of the release body 621 is located in the snap groove 2014. When the release member is in the locked position, the second end of the release body 621 is located to the left of the mating buckle. During the unlocking process, the pull ring is pulled upward and to the left, causing the first arm 6111 and the bent portion 6115 to move downward and to the right around the axis of rotation. The contact point between the pull ring 610 and the first end of the release member 620 gradually moves from the reinforcing member 61152 to the curved member 61151, pushing the second end of the release member 620 under the mating buckle, raising the mating buckle and disengaging the mating buckle from the mating protrusion.

[0102] In some embodiments, the unlocking member 620 may include an unlocking guide portion 622 located on a side of the unlocking body 621. The unlocking guide portion 622 is assembled and connected to the mounting seat 220 so that the unlocking body 621 can move on the upper housing 201.

[0103] In some embodiments, the unlocking member 620 may include an elastic member compression portion (also referred to as a spring compression portion in some technologies) 623, which is located on the side of the unlocking body 621. The elastic member compression portion 623 is assembled and connected to the mounting base 220 and the elastic member 630, so that the elastic member 630 can act on the unlocking body 621.

[0104] In some embodiments, the second end of the unlocking body 621 is provided with a first elastic leaf guide 6211 and a second elastic leaf guide 6212. A relief groove 6213 is defined between the first elastic leaf guide 6211 and the second elastic leaf guide 6212. When the unlocking member 620 is moved to the unlocked position, the mating protrusion 2013 can be positioned in the relief groove 6213, with the first elastic leaf guide 6211 positioned on one side of the mating protrusion 2013 and the second elastic leaf guide 6212 positioned on the other side of the mating protrusion 2013.

[0105] In some embodiments, the first elastic sheet guide portion 6211 has an inclined first guide slope 62111, and the inclination direction of the first guide slope is toward the right. The first guide slope 62111 of the first elastic sheet guide portion 6211 causes the thickness of the first elastic sheet guide portion 6211 to gradually increase from right to left. The right side of the first elastic sheet guide portion 6211 has a small thickness, which facilitates insertion into the gap formed by the mating buckle and the upper cover plate 3011 during the unlocking process. The left side thickness of the first elastic sheet guide portion 6211 is greater than the maximum thickness of the matching protrusion 2013. In some examples, in order to facilitate unlocking and prevent the mating buckle from tilting during the lifting process, the inclined slopes of the first elastic sheet guide portion 6211 and the second elastic sheet guide portion 6212 are the same.

[0106] The rightmost end of the first guide slope 62111 of the first spring sheet guide part 6211 is provided with a reinforced section, which is perpendicular to the surface of the cover plate, so that the thickness of the rightmost end of the first spring sheet guide part 6211 is increased, thereby increasing the thickness of the first spring sheet guide part 6211 when the first spring sheet guide part 6211 initially contacts the mating buckle during the unlocking process, thereby preventing the first spring sheet guide part 6211 from bending.

[0107] In some embodiments, the second spring clip guide portion 6212 has an inclined second guide surface 62121, with the second guide surface 62121 tilted toward the right. The second guide surface 62121 causes the thickness of the second spring clip guide portion 6212 to gradually increase from right to left. The right side of the second spring clip guide portion 6212 is thinner, facilitating insertion into the gap formed between the mating buckle and the upper cover 3011 during unlocking. The left side of the second spring clip guide portion 6212 is thicker than the maximum thickness of the mating protrusion 2013. To facilitate unlocking and prevent the mating buckle from tilting during lifting, the first and second spring clip guide portions 6211 and 6212 have the same inclined surface.

[0108] The rightmost end of the second guide slope 62121 of the second spring sheet guide part 6212 is provided with a reinforced section, which is perpendicular to the surface of the cover plate, so that the thickness of the rightmost end of the second spring sheet guide part 6212 is increased, and the thickness of the second spring sheet guide part 6212 is increased when the second spring sheet guide part 6212 initially contacts the mating buckle during the unlocking process, thereby preventing the second spring sheet guide part 6212 from bending or breaking.

[0109] The width of the relief groove 6213 is greater than the side length of the mating protrusion 6213. In the unlocked position, the mating protrusion 6213 fits between the first spring guide 6211 and the second spring guide 6212, lifting both ends of the mating buckle and facilitating unlocking. The width of the relief groove 6213 is the distance between the first spring guide 6211 and the second spring guide 6212.

[0110] In some embodiments, a first unlocking guide portion 6221 is provided on a side wall of the unlocking body 621. The first unlocking guide portion 6221 protrudes outward from the side wall of the unlocking body 621. The length of the first unlocking guide portion 6221 is shorter than the length of the unlocking body 621, and the upper surface of the first unlocking guide portion 6221 is lower than the upper surface of the unlocking body 621, so that the first unlocking guide portion 6221 slides within the first fixing portion.

[0111] The first spring compression portion 6231 is located outside the first unlocking guide portion 6221. The first spring compression portion 6231 protrudes outward relative to the side wall of the unlocking body 621. The length of the first spring compression portion 6231 is shorter than the length of the first unlocking guide portion 622.

[0112] For example, the left end of the first spring compression portion 6231 is flush with the left end of the first unlocking guide portion 6221. For example, to ensure that the forces on both sides of the unlocking body 621 are balanced during the unlocking process, the unlocking body 621 is further provided with a second unlocking guide portion 6222 and a second spring compression portion 6232.

[0113] The other side wall of the unlocking body 621 is provided with a second unlocking guide portion 6222 . The second unlocking guide portion 6222 protrudes outward relative to the side wall of the unlocking body 621 . The side of the second unlocking guide portion 6222 is connected to the other side wall of the unlocking body 621 .

[0114] Exemplarily, the length of the second unlocking guide portion 6222 is smaller than the length of the unlocking body 621, the upper surface of the second unlocking guide portion 6222 is lower than the upper surface of the unlocking body 621, and the second unlocking guide portion 6222 is assembled with the mounting seat 220 so that the second unlocking guide portion 6222 slides in the second fixed portion.

[0115] In some embodiments, one end of the second unlocking guide portion 6222 may not be flush with one end of the unlocking body 621. Of course, in some embodiments, one end of the second unlocking guide portion 6222 may be flush with one end of the unlocking body 621.

[0116] The second spring compression portion 6232 is located outside the second unlocking guide portion 6222. The second spring compression portion 6232 protrudes outward relative to the side wall of the unlocking body 621. The length of the second spring compression portion 6232 is shorter than the length of the second unlocking guide portion 6222.

[0117] In some examples, the second elastic member compression portion 6232 is located outside the second unlocking guide portion 6222. The second elastic member compression portion 6232 protrudes outward relative to the sidewall of the second unlocking guide portion 6222. The length of the second elastic member compression portion 6232 is less than the length of the second unlocking guide portion 6222. The second elastic member compression portion 6232 can be assembled to connect the mounting base 220 and the elastic member 630.

[0118] The first unlocking guide portion 6221 is symmetrically arranged with the second unlocking guide portion 6222 , and the second spring compression portion 6232 is symmetrically arranged with the first spring compression portion 6231 .

[0119] In some embodiments, the top surface of the unlocking body 621 is provided with a first step 6214, which divides the top surface of the unlocking body 621 into two sub-bodies 6216 and 6215 of different heights. To prevent the unlocking component 600 from interfering with external structures, the right end of the first step 6214 does not extend beyond the left edge of the locking groove 2014 when in the locked position.

[0120] The first sub-body 6216 is located on the left side of the first step 6214 , the second sub-body 6215 is located on the right side of the first step 6214 , and the upper surface of the first sub-body 6216 is higher than the upper surface of the second sub-body 6215 .

[0121] The first end of the first sub-body abuts the pull ring. The first end of the first step connects to the second end of the first sub-body. The second sub-body connects to the second end of the first step. The distance between the upper surface of the second sub-body and the upper surface of the cover plate is smaller than the distance between the upper surface of the first sub-body and the upper surface of the cover plate.

[0122] Figure 9c is a third-angled schematic diagram of an unlocking member according to some embodiments. As shown in Figure 9c, the lower surface of the first spring guide portion 6211 is raised to form a first limiting protrusion 6226, which allows the lower surface of the first spring guide portion 6211 to contact the surface of the locking groove 2014. This prevents the locking groove 2014 from causing the first spring guide portion 6211 to become suspended in the air, thereby increasing the strength of the unlocking member 600.

[0123] In some embodiments, the lower surface of the first spring clip guide portion 6211 can be raised to form a first limiting protrusion 6226. The first limiting protrusion 6226 reduces the distance between the lower surface of the first spring clip guide portion 6211 and the upper surface of the snap groove 2014, so that the lower surface of the first spring clip guide portion 62112 contacts the surface of the snap groove 2014, so that the distance between the contact position between the mating buckle 1061 and the first spring clip guide portion 6211 and the upper surface of the snap groove 2014 is reduced as much as possible, thereby facilitating the sliding of the mating buckle 1061 in the first spring clip guide portion 6211.

[0124] In some embodiments, the upper surface of the second sub-body 6215 is lower than the upper surface of the first sub-body 6216, reducing the lifting height of the first spring guide portion 6211, facilitating the sliding of the mating buckle 1061 along the first spring guide portion 6211 to the upper surface of the second sub-body 6215, thereby achieving the separation of the mating buckle 1061 and the matching protrusion 2013.

[0125] The snap groove 2014 limits the first limiting protrusion 6226 in the left and right directions. The snap groove 2014 allows the first elastic sheet guide portion 6211 to move within the snap groove 2014, preventing the unlocking member from moving to the left beyond the range when returning to its original position.

[0126] The lower surface of the second spring guide portion 6212 is raised to form a second limiting protrusion 6227, so that the lower surface of the second spring guide portion 6212 contacts the surface of the snap groove 2014, preventing the snap groove 2014 from causing the second spring guide portion 6212 to be suspended in the air, thereby increasing the strength of the unlocking component 600.

[0127] In some embodiments, the lower surface protrusion of the second spring clip guide portion 6212 forms a second limiting protrusion 6227, and the second limiting protrusion 6227 reduces the distance between the lower surface of the second spring clip guide portion 6212 and the upper surface of the snap groove 2014, so that the lower surface of the second spring clip guide portion 6212 contacts the surface of the snap groove 2014, so that the distance between the contact position between the mating buckle 1061 and the second spring clip guide portion 6212 and the upper surface of the snap groove 2014 is reduced as much as possible, thereby facilitating the sliding of the mating buckle 1061 in the second spring clip guide portion 6212.

[0128] In some embodiments, the upper surface of the second sub-body 6215 is lower than the upper surface of the first sub-body 6216, reducing the lifting height of the second elastic leaf guide 6212 and facilitating the sliding of the engaging buckle 1061 along the second elastic leaf guide 6212 to the upper surface of the second sub-body 6215, thereby separating the engaging buckle 1061 from the mating protrusion 2013. The snap groove 2014 limits the left and right position of the second limiting protrusion 6227, allowing the second elastic leaf guide 6212 to move within the snap groove 2014, preventing the unlocking member from moving leftward beyond its range when returning to its original position.

[0129] Figure 10a is a structural diagram of another unlocking member according to some embodiments, and Figure 10b is a structural diagram of another unlocking member according to some embodiments. As shown in Figures 10a and 10b, in some embodiments, a contact portion 624 is formed at one end of the unlocking member 621. The contact portion 624 is configured to contact the pull ring body 611 so that the unlocking member 621 can be pushed by the contact portion 624 when the pull ring body 611 rotates. For example, the top of the contact portion 624 may be flush with the top of one end of the unlocking member 621. However, in some embodiments, the top of the contact portion 624 may be higher or lower than the top of one end of the unlocking member 621.

[0130] In some embodiments, the width of the contact portion 624 is greater than the width of one end of the unlocking body 621 to increase the contact area between the pull ring body 611 and the unlocking member 620, thereby facilitating the pull ring body 611 to push the contact portion 624. For example, one side of the contact portion 624 protrudes from a side edge of the first unlocking guide portion 6221, and the other side of the contact portion 624 protrudes from a side edge of the second unlocking guide portion 6222.

[0131] In some embodiments, one side of the contact portion 624 is flush with a side of the first elastic member compression portion 6231 , and the other side of the contact portion 624 is flush with a side of the second elastic member compression portion 6232 .

[0132] In some embodiments, a first connecting block 6223 is formed at the top of one end of the first unlocking guide portion 6221. The first connecting block 6223 connects the unlocking body 621 and the first unlocking guide portion 6221. The top of the first connecting block 6223 may be flush with the top of the unlocking body 621. The first connecting block 6223 reinforces the connection between the first unlocking guide portion 6221, the unlocking body 621, and the contact portion 624. Exemplarily, a first connecting surface 62231 is formed on the first connecting block 6223. The first connecting surface 62231 extends obtusely from the side of the contact portion 624 to the side of the unlocking body 621. The first connecting surface 62231 forms an obtuse angle with the side of the unlocking body 621 and the side of the contact portion 624. When the unlocking member 620 moves to the unlocked position, the first connecting surface 62231 can be fixedly connected to the side of the mounting base 220.

[0133] In some embodiments, a second connecting block 6224 is formed at the top of one end of the second unlocking guide portion 6222. The second connecting block 6224 connects the unlocking body 621 and the second unlocking guide portion 6222. The top of the second connecting block 6224 may be flush with the top of the unlocking body 621. The second connecting block 6224 reinforces the connection between the second unlocking guide portion 6222, the unlocking body 621, and the contact portion 624. Exemplarily, a second connecting surface 62241 is formed on the second connecting block 6224. The second connecting surface 62241 extends obtusely from the side of the contact portion 624 to the side of the unlocking body 621. The second connecting surface 62241 forms an obtuse angle with the side of the unlocking body 621 and the side of the contact portion 624. When the unlocking member 620 moves to the unlocked position, the second connecting surface 62241 can be fixedly connected to the side of the mounting base 220.

[0134] Figure 11a is a structural diagram of another unlocking member according to some embodiments, and Figure 11b is a structural diagram of another unlocking member according to some embodiments. As shown in Figures 11a and 11b, in some embodiments, one side of the contact portion 624 protrudes from the side of the first elastic member compression portion 6231, and the other side of the contact portion 624 protrudes from the side of the second elastic member compression portion 6232.

[0135] In some embodiments, a first assembly protrusion 6241 and a second assembly protrusion 6242 are formed on the bottom of the contact portion 624. The first assembly protrusion 6241 and the second assembly protrusion 6242 are formed by protruding outward from the bottom surface of the contact portion 624. The first assembly protrusion 6241 is located on one side of the contact portion 624, and the second assembly protrusion 6242 is located on the other side of the contact portion 624. The first assembly protrusion 6241 and the second assembly protrusion 6242 are assembled and connected to the upper housing 201.

[0136] Figure 12a is a schematic diagram of the first angle structure of an upper shell provided according to some embodiments. Figure 12b is a schematic diagram of the second angle structure of an upper shell provided according to some embodiments. Figure 12c is a schematic diagram of a cross-section of an upper shell provided according to some embodiments. Figure 12d is a schematic diagram of a cross-section of an upper shell provided according to some embodiments. As shown in Figures 12a to 12d, the upper shell includes a cover plate 2011 and upper side plates 2012 located on both sides of the cover plate. An axon 230 is respectively provided at corresponding positions of the two upper side plates 2012. The first axial hole 6117 and the second axial hole 6118 are respectively inserted into the axons 230 at corresponding positions. When the pull ring is pulled, the axial hole rotates around the axon to cause the pull ring to rotate.

[0137] The first upper side plate is provided with a first axon; the second upper side plate is provided with a second axon.

[0138] In some embodiments, a first clamping shaft 211 is provided on the first upper side plate 20121, and a second clamping shaft 212 is provided on the second upper side plate 20122. The first clamping shaft 211 can be inserted into the first shaft hole 6117, and the second clamping shaft 212 can be inserted into the second shaft hole 6118. When the pull ring is pulled, the first shaft hole 6117 rotates on the first clamping shaft 211, and the second shaft hole 6118 rotates on the second clamping shaft 212, so that the pull ring 610 rotates on the upper housing 201.

[0139] The cover 2011 is provided with a mounting base 220. The unlocking member 620 is movably disposed within the mounting base 220 and has a locked position and an unlocked position during movement relative to the mounting base 220. In other words, the mounting base 220 is movably connected to the unlocking member 620. For example, the side of the unlocking member 620 can be assembled and connected to the mounting base 220.

[0140] Mounting base 220 includes a first fixing portion 221 and a second fixing portion 222 disposed opposite each other, with a movable slot 223 defined between the first fixing portion 221 and the second fixing portion 222. An unlocking member 620 is movably positioned within movable slot 223 via an elastic member and can extend out of the movable slot 223 to engage with a mating buckle when driven by the first arm 6111. The movable slot 223 constrains the movement of unlocking member 620, limiting its movement to either a direction away from or a direction toward the mating buckle (i.e., left-right). Exemplarily, an unlocking body 621 is positioned within movable slot 223, with the first fixing portion 221 and the second fixing portion 222 limiting the unlocking body 621 on opposing sides.

[0141] For example, the first fixing portion 221 is provided with a first avoidance groove 2211 and a second avoidance groove 2212 , and the first avoidance groove 2211 and the second avoidance groove 2212 are communicated with each other. The first avoidance groove 2211 is recessed relative to the second avoidance groove 2212 .

[0142] The first spring compression portion 6231 is embedded in the first avoidance groove 2211. In other words, the first avoidance groove 2211 is assembled and connected to the first elastic member compression portion 6231. The length of the first avoidance groove 2211 is greater than the length of the first spring compression portion 6231, and the first elastic member 631 is located on the left side of the first spring compression portion 6231. One end of the first elastic member 631 contacts the side wall of the first spring compression portion 6231, and the other end of the first elastic member 631 contacts the end of the second avoidance groove 2212. During the unlocking process, the first arm 6111 gradually changes from being perpendicular to the cover plate to being parallel to the cover plate, pushing the spring compression portion 623 to slide from left to right in the first avoidance groove 2211, and the first elastic member 631 is compressed by force. After the external force is removed, the elastic member resumes its deformation to drive the unlocking body back to its original position.

[0143] For example, the edge of the first spring compression portion 6231 can be rectangular or square, or other shapes. In order to reduce the friction between the spring compression portion and the first avoidance groove 2211, the edge of the spring compression portion is arc-shaped, and the corresponding first avoidance groove 2211 is arc-shaped.

[0144] In some embodiments, the first unlocking guide 6221 is embedded in the second avoidance groove 2221. In other words, the second avoidance groove 2221 is assembled and connected to the first unlocking guide 6221. The second avoidance groove 2221 is longer than the first unlocking guide 6221. During the unlocking process, the first unlocking guide 6221 slides within the second avoidance groove 2221. The right side wall of the second avoidance groove 2221 limits the first unlocking guide 6221 to the left and right, preventing it from sliding rightward beyond the preset position.

[0145] In order to balance the force on the unlocking body 621 , the second fixing portion 222 is provided with a third avoidance groove 2221 and a fourth avoidance groove 2222 . The third avoidance groove 2221 is connected to the fourth avoidance groove 2222 .

[0146] For example, the third avoidance groove 2221 may be symmetrical with the first avoidance groove 2211 , and the fourth avoidance groove 2222 may be symmetrical with the second avoidance groove 2212 , so as to ensure balanced force on the unlocking body 621 .

[0147] In some embodiments, the second spring compression portion 6232 is embedded in the third avoidance groove 2221. In other words, the third avoidance groove 2221 is assembled and connected to the second elastic member compression portion 6232. The length of the third avoidance groove 2221 is greater than the length of the second spring compression portion 6232, and the second elastic member is located on the left side of the second spring compression portion 6232. One end of the second elastic member contacts the side wall of the second spring compression portion 6232, and the other end of the second elastic member contacts the end of the fourth avoidance groove 2222. During the unlocking process, the first arm 6111 gradually changes from being perpendicular to the cover plate to being parallel to the cover plate, pushing the second spring compression portion 6232 to slide from left to right in the third avoidance groove 2221, and the elastic member is compressed by force. After the external force is removed, the elastic member resumes its deformation to drive the unlocking body back to its original position.

[0148] In some embodiments, the fourth avoidance groove 2222 is assembled and connected to the second unlocking guide portion 6222. The fourth avoidance groove 2222 can be longer than the second unlocking guide portion 6222. During the unlocking process, the second unlocking guide portion 6222 slides within the fourth avoidance groove 2222. The right side wall of the fourth avoidance groove 2222 limits the right position of the second unlocking guide portion 6222, reducing the risk of the second unlocking guide portion 6222 sliding to the right beyond the preset position.

[0149] A second recessed area 241 is defined on the surface of the cover plate 2011 . The upper surface of the second recessed area 241 is recessed relative to the lower surface of the movable groove 223 to avoid the bending portion 6115 .

[0150] To avoid the first arm 6111, the first fixing portion 221 is provided with a first arm avoiding portion 2311, and the second fixing portion 222 is provided with a second arm avoiding portion 2321. When the unlocking member 600 is in the unlocked position, the first arm 6111 is located above the first arm avoiding portion 2311 and the second arm avoiding portion 2321.

[0151] For example, the upper surface of the first arm avoidance portion 2311 is recessed relative to the upper surface of the first fixed portion 221, and the height difference between the upper surface of the first arm avoidance portion 2311 and the upper surface of the first fixed portion 221 is greater than or equal to the thickness of the first arm 6111. When the unlocking component 600 is in the unlocking position, the upper surface of the first arm 6111 does not exceed the upper surface of the first fixed portion 221.

[0152] The upper surface of the second arm avoidance portion 2321 is recessed relative to the upper surface of the second fixed portion 222. The height difference between the upper surface of the second arm avoidance portion 2321 and the upper surface of the second fixed portion 222 is greater than or equal to the thickness of the first arm 6111. When the unlocking component 600 is in the unlocking position, the upper surface of the first arm 6111 does not exceed the upper surface of the second fixed portion 222.

[0153] In some embodiments, a third recessed area 240 is provided at the left end of the first upper side plate 20121, and the second arm 6112 is located in the third recessed area 240. The step formed by the third recessed area 240 limits the sidewall of the second arm 6112, preventing the pull ring from moving out of position during the unlocking and recovery phase.

[0154] The corresponding position of the second upper side plate 20122 may correspond to a fourth recessed area 250, and the fourth arm 6114 is located in the fourth recessed area 250. The step formed by the fourth recessed area 250 limits the side wall of the fourth arm 6114 to prevent the pull ring from moving out of its original position during the unlocking and recovery stage.

[0155] The surface of the support plate 2016 is recessed to form a fifth recessed area 260, and the third arm 6113 is located in the fifth recessed area 260. The step formed by the fifth recessed area 260 limits the side wall of the third arm 6113 to prevent the pull ring from exceeding the original position during the unlocking and recovery stage.

[0156] In some embodiments, the second recessed area, the third recessed area, the fourth recessed area and the fifth recessed area constitute a pull ring mounting portion, a first axon is provided in the third recessed area (which can be understood as the first clamping shaft 211 mentioned above), a second axon 251 is provided in the fourth recessed area 250 (which can be understood as the second clamping shaft 212 mentioned above), and the first axis hole 6117 and the second axis hole 6118 are respectively inserted into the first axon and the second axon 251 so that the pull ring rotates around the axon.

[0158] In some embodiments, a second relief surface 2225 is formed at one end of the second fixing portion 222, and the second relief surface 2225 is located on the side of the second pull ring relief portion 2224. The second relief surface 2225 can be used to avoid the second connecting surface 62241. The second relief surface 2225 can also serve as an assembly guide for the unlocking member 620, thereby facilitating the assembly of the unlocking member 620 with the mounting base 220.

[0159] In some embodiments, a first guide groove 20111 is formed on the top surface of the cover plate 2011. The first guide groove 20111 can extend from one end of the cover plate 2011 to below the first avoidance groove 2211. The first guide groove 20111 serves as a guide, facilitating the assembly of the first elastic member 631 into the first avoidance groove 2211. The first guide groove 20111 also serves to position the first elastic member 631 during deformation, ensuring a more uniform deformation of the first elastic member 631.

[0160] In some embodiments, a second guide groove 20112 is formed on the top surface of the cover plate 2011. The second guide groove 20112 can extend from one end of the cover plate 2011 to below the third avoidance groove 2221. The second guide groove 20112 serves as a guide, facilitating the assembly of the second elastic member 632 into the third avoidance groove 2221.

[0161] Figure 13c is a partial view of another upper housing according to some embodiments, and Figure 13d is an enlarged partial view of another upper housing according to some embodiments. As shown in Figures 13c and 13d, in some embodiments, a first mounting portion 2017 is formed at one end of the first fixing portion 221. The first mounting portion 2017 is located at an edge of one side of the cover plate 2011 and extends along the length of the cover plate 2011. The first mounting portion 2017 is used to assemble and connect with the first mounting protrusion 6241. The first mounting portion 2017 can limit the first mounting protrusion 6241 to facilitate movement of the unlocking member 620 along the length of the cover plate 2011. For example, one end of the first mounting portion 2017 can be flush with one end of the cover plate 2011.

[0162] In some embodiments, a second mounting portion 2018 is formed at one end of the second fixing portion 222. The second mounting portion 2018 is located at the edge of the other side of the cover plate 2011 and extends along the length of the cover plate 2011. The second mounting portion 2018 is configured to assemble with and connect to the second mounting protrusion 6242.

[0165] Figure 14a is a schematic cross-sectional view of an upper housing and unlocking component according to some embodiments; Figure 14b is a schematic cross-sectional view of an upper housing and unlocking component according to some embodiments. Figure 14c is a schematic cross-sectional view of an upper housing and unlocking component according to some embodiments. Figures 14a and 14b are cross-sectional views of the unlocking component 600 in the locked position, while Figure 14c is a cross-sectional view of the unlocking component 600 in the unlocked position.

[0166] When the unlocking member 600 is in the locked position, the first arm 6111 and the bent portion 6115 are perpendicular to the cover plate 2011 , and the bent portion 6115 is located above the second recessed area 241 .

[0167] During the unlocking process, the pull ring rotates around the axle, pulling it upward and leftward. The first arm 6111 and the bent portion 6115 move downward and rightward about the axis of rotation, gradually changing from contact between the reinforcing member 61152 and the unlocking member 620 to contact between the bent portion 61151 and the unlocking member 620, pushing the unlocking member 620 to the right. The guide portion moves from left to right, causing the mating protrusion 6213 to engage between the first and second spring guide portions 6211 and 6212, thereby lifting both ends of the mating buckle 1061. The mating buckle 1061 gradually rises along the inclined surfaces of the first and second spring guide portions 6211 and 6212.

[0168] In some embodiments, when the unlocking component 600 is in the locked position, the first arm 6111 is located on one side of the center line of the first axial hole 6117 and the second axial hole 6118; when the unlocking component 600 is in the locked position, part of the first arm 6111 is located on the other side of the center line of the first axial hole 6117 and the second axial hole 6118.

[0169] In some embodiments, when the unlocking component 600 is in the locked position, the bending portion 6115 is located on one side of the center line of the first axial hole 6117 and the second axial hole 6118; when the unlocking component 600 is in the locked position, the bending portion 6115 is located on the other side of the center line of the first axial hole 6117 and the second axial hole 6118.

[0170] In some embodiments, when the unlocking component 600 is in the locked position, the first arm 6111 and the bent portion 6115 are located on one side of the center line of the first axial hole 6117 and the second axial hole 6118; when the unlocking component 600 is in the locked position, part of the first arm 6111 and the bent portion 6115 are located on the other side of the center line of the first axial hole 6117 and the second axial hole 6118.

[0171] In some embodiments, when the unlocking component 600 is in the locked position, the first arm 6111 and the bent portion 6115 are located on one side of the center line of the first axial hole 6117 and the second axial hole 6118; when the unlocking component 600 is in the locked position, the first arm 6111 and the bent portion 6115 are located on the other side of the center line of the first axial hole 6117 and the second axial hole 6118.

[0172] In some embodiments, the centerline of the first shaft hole 6117 and the second shaft hole 6118 coincides with the centerline of the first axon and the second shaft hole 6118 .

[0173] In some embodiments, when the unlocking member 600 is in the locked position, the first arm 6111 and the bent portion 6115 of the pull ring 610 are located to the left of the centerline between the first shaft hole 6117 and the second shaft hole 6118. When the unlocking member 600 is in the unlocked position, the first arm 6111 and the bent portion 6115 of the pull ring 610 are located to the right of the centerline between the first shaft hole 6117 and the second shaft hole 6118.

[0174] In some embodiments, when the unlocking component 600 is in the locked position, the distance between the rightmost end face of the reinforcement component 61152 and the leftmost end face of the first arm 6111 is smaller than the distance between the top end of the bending component 61151 and the leftmost end face of the first arm 6111 when the unlocking component 600 is in the unlocked position, so that the position of the first end of the unlocking body 621 when the unlocking component 600 is in the unlocked position is to the left of the position of the first end of the unlocking body 621 when the unlocking component 600 is in the locked position.

[0175] The first elastic member 630 is located within the first avoidance groove 2211 and within the space formed by the unlocking body 621 and the mounting base 220. The left end of the first elastic member 630 abuts against the first spring compression portion 6231. Pulling the pull ring upward and to the left causes the first arm 6111 and the bent portion 6115 to move about the rotation axis toward the lower right, causing the first spring compression portion 6231 to move from left to right, compressing the first elastic member 630.

[0176] The second elastic member 640 is located within the first avoidance groove 2221 and within the space formed by the unlocking body 621 and the mounting base 220. The left end of the second elastic member 640 abuts against the second spring compression portion 6232. When the pull ring is pulled upward and to the left, the first arm 6111 and the bent portion 6115 move about the rotation axis toward the lower right, causing the second spring compression portion 6232 to move from left to right, compressing the second elastic member 620.

[0177] When the unlocking member 600 is in the unlocked position, the first arm 6111 and the bent portion 6115 are parallel to the cover plate, and the curved portion 61151 of the bent portion 6115 contacts the unlocking member. The mating protrusion 6213 is located between the first spring guide 6211 and the second spring guide 6212, and the mating buckle 1061 is located above the first and second spring guides 6211 and 6212, disengaging the mating buckle 1061 from the mating protrusion 6213, thereby unlocking the optical module from the cage.

[0178] In some embodiments, when the unlocking member 600 is in the locked position, the upper surface of the bent portion 6115 is higher than the upper surface of the first arm 6111. Therefore, in the unlocked position, the bent portion 6115 protrudes to the right relative to the first arm 6111. To prevent interference between the pull ring 610 and the mounting base 220, a first pull ring avoidance portion 2214 is provided at the left end of the first fixing portion 221, and a second pull ring avoidance portion 2224 is provided at the left end of the second fixing portion 222. The first pull ring avoidance portion 2214 and the second pull ring avoidance portion 2224 are used to allow the bent portion 6115 to avoid interference during the unlocking process.

[0179] In some examples, a first pull-ring avoidance portion 2214 is formed at one end of the first fixing portion 221. The first pull-ring avoidance portion 2214 is formed by a partial depression at one end of the first fixing portion 221. The first pull-ring avoidance portion 2214 is adjacent to the second fixing portion 222 and is used to avoid one end of the bent portion 6115, thereby reducing the risk of interference between the bent portion 6115 and the first fixing portion 221.

[0180] In some embodiments, a second pull-ring avoidance portion 2224 is formed at one end of the second fixing portion 222. The second pull-ring avoidance portion 2224 is formed by a partial depression at one end of the second fixing portion 222. The second pull-ring avoidance portion 2224 is close to the first fixing portion 221 and is used to avoid the other end of the bent portion 6115, thereby reducing the risk of interference between the bent portion 6115 and the second fixing portion 222.

[0181] Figure 15a is an assembly diagram of another upper housing and unlocking component according to some embodiments, and Figure 15b is a partially enlarged view of another upper housing and unlocking component according to some embodiments. As shown in Figures 15a and 15b, in some embodiments, the bent portion 6115 contacts the end surface of the contact portion 624. When the pull ring 610 rotates, the bent portion 6115 rotates, thereby pushing the unlocking member 620 to move. Exemplarily, when the unlocking member 620 is in the locked position, the side edge of the reinforcement member 61152 abuts the contact portion 624; when the unlocking member 620 is in the unlocked position, the side edge of the curved member 61151 abuts the contact portion 624.

[0182] In some embodiments, when the unlocking member 620 moves to the unlocked position, the contact portion 624 moves toward the first pull ring avoidance portion 2214 and the second pull ring avoidance portion 2224. For example, when the unlocking member 620 moves to the unlocked position, the first connecting surface 62231 contacts the first avoidance surface 2215, and the second connecting surface 62241 contacts the second avoidance surface 2255.

[0183] Figure 16a is an assembly diagram of another upper housing and unlocking component according to some embodiments, Figure 16b is a partially enlarged view of another upper housing and unlocking component according to some embodiments, and Figure 16c is a cross-sectional view of another upper housing and unlocking component according to some embodiments. As shown in Figures 16a to 16c, in some embodiments, the first connecting portion 613 and the second connecting portion 614 respectively contact the end surfaces of the contact portion 624. When the pull ring 610 rotates, the first connecting portion 613 and the second connecting portion 614 rotate, thereby pushing the unlocking member 620 to move. Exemplarily, when the unlocking member 620 is in the locked position, the bottoms of the first driving surface 6131 and the second driving surface 6141 abut the contact portion 624. When the unlocking member 620 is in the unlocked position, the tops of the first driving surface 6131 and the second driving surface 6141 and the top of the first arm 6111 abut the contact portion 624.

[0184] In some embodiments, the first assembly protrusion 6241 is assembled and connected to the first assembly portion 2017, and the second assembly protrusion 6242 is assembled and connected to the second assembly portion 2018. The first assembly portion 2017 and the second assembly portion 2018 can limit the assembly unlocking member 620 so that the first connecting portion 613 and the second connecting portion 614 can fully contact the contact portion 624.
