[0081] Some embodiments of the present disclosure will be described below in detail with reference to the accompanying drawings. However, the described embodiments are only some of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments provided in the present disclosure, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present disclosure.

[0082] Unless otherwise required by the context, throughout the specification and claims, the term "comprising" is to be interpreted as meaning "including but not limited to"; the terms "first", "second" are not to be interpreted as indicating or implying relative importance or indicating the upper limit of the number; the term "multiple" means two or more; the term "connected" is to be interpreted broadly, for example, "connected" can be fixed connection, or detachable connection, or integral, can be directly connected, or indirectly connected through an intermediate medium; the use of the terms "adapted for" or "configured for" means open and inclusive language, which does not exclude devices adapted for or configured for performing additional tasks or steps; the terms "parallel", "vertical", "same", "consistent", "flush" and the like are not limited to absolute mathematical theoretical relationship, but also include acceptable error range generated in practice, and also include differences based on the same design concept but due to manufacturing reasons.

[0083] In optical communication technology, in order to establish information transmission between information processing devices, information needs to be loaded onto light, and the transmission of information is realized by the propagation of light. Here, the light loaded with information is an optical signal. The optical signal can reduce the loss of optical power when transmitted in the information transmission device, so as to realize high-speed, long-distance and low-cost information transmission. The signal that can be recognized and processed by the information processing device is an electrical signal. The information processing device usually includes an optical network terminal (Optical Network Unit, ONU), gateway, router, switch, mobile phone, computer, server, tablet computer, television and the like, and the information transmission device usually includes optical fiber and optical waveguide and the like.

[0084] The optical module can realize the mutual conversion between the optical signal and the electrical signal between the information processing device and the 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 with 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 with an optical network terminal; a first optical signal from the optical fiber is transmitted to the optical module, the optical module 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, the optical module converts the second electrical signal into a second optical signal, and transmits the second optical signal to the optical fiber. Since multiple information processing devices can transmit information through electrical signals, at least one of the multiple information processing devices needs to be directly connected with the optical module, without the need for all information processing devices to be directly connected with the optical module. Here, the information processing device directly connected with the optical module is referred to as the host machine of the optical module. In addition, the optical signal input end or the optical signal output end of the optical module can be referred to as an optical port, and the electrical signal input end or the electrical signal output end of the optical module can be referred to as an electrical port.

[0085] Figure 1 Figure 1 is a schematic diagram of a part of an optical communication system according to some embodiments. As shown in Figure 1, the optical communication system mainly comprises 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. Figure 1

[0086] One end of the optical fiber 101 extends towards the remote information processing device 1000, and the other end of the optical fiber 101 is connected to the optical module 200 through an optical port of the optical module 200. The optical signal can be totally reflected in the optical fiber 101, and the propagation of the optical signal in the direction of total reflection can maintain the original optical power. The optical signal is totally reflected multiple times in the optical fiber 101 to transmit the optical signal from the remote information processing device 1000 to the optical module 200, or to transmit the optical signal from the optical module 200 to the remote information processing device 1000, thereby realizing long-distance and low-power-loss information transmission.

[0087] The optical communication system can comprise one or more optical fibers 101, and the optical fiber 101 can be detachably connected 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 to receive a data signal from the optical module 200, or to monitor or control the working state of the optical module 200.

[0088] The host computer 100 comprises a housing substantially in the shape of a cuboid, and an optical module connecting hole 102 arranged on the housing. The optical module connecting hole 102 is configured to access the optical module 200, so that the host computer 100 and the optical module 200 establish a unidirectional or bidirectional electrical signal connection.

[0089] ​The host computer 100 further comprises an external electrical connection hole configured to access an electrical signal network. For example, the external electrical connection hole comprises a Universal Serial Bus (USB) connection hole or a network cable connection hole 104 configured to access a network cable 103 to establish a one-way or two-way electrical signal connection between the host computer 100 and 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 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 emitted by the local information processing device 2000 is transmitted to the host computer 100 through the network cable 103, and the host computer 100 generates a second electrical signal according to the third electrical signal. The second electrical signal from the host computer 100 is transmitted to the optical module 200, 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 in the optical fiber 101 to the remote information processing device 1000. For example, the 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 according to the first electrical signal, and the fourth electrical signal is transmitted to the local information processing device 2000. It should be noted that the optical module is a tool for converting optical signals and electrical signals, and the information does not change in the conversion process of the optical signals and the electrical signals, and the encoding and decoding mode of the information can change.

[0090] The host computer 100 comprises an optical line terminal (OLT), an optical network terminal (ONT), or a data center server in addition to the optical network terminal.

[0091] Figure 2 A partial structure diagram of a host computer according to some embodiments is provided. In order 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. As Figure 2 shown, the host computer 100 further comprises a PCB circuit board 105 arranged in the housing, a cage 106 arranged on the surface of the PCB circuit board 105, a heat sink 107 arranged on the cage 106, and an electrical connector arranged inside the cage 106. The electrical connector is configured to access the electrical port of the optical module 200; the heat sink 107 has a protruding structure such as fins to increase the heat dissipation area.

[0092] The light module 200 is inserted into the cage 106 of the host computer 100, and the light module 200 is fixed by the cage 106. The heat generated by the light module 200 is conducted to the cage 106, and then diffused through the heat sink 107. After the light module 200 is inserted into the cage 106, the electrical port of the light module 200 is connected to the electrical connector inside the cage 106, so that the light module 200 and the host computer 100 establish a bidirectional electrical signal connection. In addition, the optical port of the light module 200 is connected to the optical fiber 101, so that the light module 200 and the optical fiber 101 establish a bidirectional optical signal connection.

[0093] Figure 3 A structure of a light module according to some embodiments Figure 1 .An exploded view of a light module according to some embodiments Figure 4 As shown in FIGS. 1 and 2, the light module 200 includes a shell, a circuit board 300 arranged in the shell, a light emitting component 400, and a light receiving component 500. However, the present disclosure is not limited thereto, and in some embodiments, the light module 200 includes one of the light emitting component 400 and the light receiving component 500. Figure 3 Figure 4 The shell includes an upper shell 201 and a lower shell 202. The upper shell 201 is covered on the lower shell 202 to form the above-mentioned shell having two openings 204 and 205. The outer contour of the shell generally presents a square body.

[0094] In some embodiments, the lower shell 202 includes a bottom plate 2021 and two lower side plates 2022 arranged perpendicularly to the bottom plate 2021 on both sides of the bottom plate 2021. The upper shell 201 includes a cover plate 2011, and the cover plate 2011 is covered on the two lower side plates 2022 of the lower shell 202 to form the above-mentioned shell.

[0095] In some embodiments, the lower shell 202 includes a bottom plate 2021 and two lower side plates 2022 arranged perpendicularly to the bottom plate 2021 on both sides of the bottom plate 2021. The upper shell 201 includes a cover plate 2011 and two upper side plates arranged perpendicularly to the cover plate 2011 on both sides of the cover plate 2011. The two upper side plates and the two lower side plates 2022 are combined to achieve that the upper shell 201 is covered on the lower shell 202.

[0096] The direction of the line connecting the two openings 204 and 205 can be consistent with the length direction of the light module 200, or can be inconsistent with the length direction of the light module 200. For example, the opening 204 is located at the end (right end) of the light module 200, and the opening 205 is also located at the end of the light module 200.

[0097] The direction of the line connecting the two openings 204 and 205 can be consistent with the length direction of the light module 200, or can be inconsistent with the length direction of the light module 200. For example, the opening 204 is located at the end (right end) of the light module 200, and the opening 205 is also located at the end of the light module 200. Figure 3 Figure 3 ​Or, the opening 204 is located at the end of the optical module 200, and the opening 205 is located at the side of the optical module 200. The opening 204 is an electrical port, and the gold fingers of the circuit board 300 extend from the electrical port and are inserted into the electrical connector of the host computer 100; the opening 205 is an optical port configured to access the external optical fiber 101 so that the optical fiber 101 is connected to the optical transmitting component 400 and the optical receiving component 500 in the optical module 200.

[0098] The upper shell 201 and the lower shell 202 are combined to facilitate the installation of the circuit board 300, the optical transmitting component 400, and the optical receiving component 500 into the shells, and the shells can encapsulate and protect the devices. In addition, when the circuit board 300, the optical transmitting component 400, and the optical receiving component 500 are assembled, the positioning components, heat dissipation components, and electromagnetic shielding components of these devices can be arranged, which is conducive to the automated production.

[0099] In some embodiments, the upper shell 201 and the lower shell 202 are made of metal materials, which is conducive to electromagnetic shielding and heat dissipation.

[0100] In some embodiments, the optical module 200 further includes an unlocking component 600 located outside the shell of the optical module 200. The unlocking component 600 is configured to achieve the 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.

[0101] For example, the unlocking component 600 is located outside the two lower side plates 2022 of the lower shell 202 and includes a clamping component matched with the cage 106 of the host computer 100. When the optical module 200 is inserted into the cage 106, the clamping component of the unlocking component 600 fixes the optical module 200 in the cage 106; when the unlocking component 600 is pulled, the clamping component of the unlocking component 600 moves, thereby changing the connection relationship between the clamping component and the host computer, releasing the fixation between the optical module 200 and the host computer, and enabling the optical module 200 to be pulled out of the cage 106.

[0102] Circuit board 300 includes circuit traces, electronic components, and chips. The circuit traces connect the electronic components and chips according to the circuit design to achieve functions such as power supply, electrical signal transmission, and grounding. Electronic components may include, for example, capacitors, resistors, transistors, and metal-oxide-semiconductor field-effect transistors (MOSFETs). Chips may include, for example, microcontroller units (MCUs), laser driver chips, transimpedance amplifiers (TIAs), limiting amplifiers (LIAs), clock and data recovery chips (CDRs), power management chips, and digital signal processing (DSP) chips.

[0103] Circuit board 300 is generally a rigid circuit board. Due to its relatively hard material, the rigid circuit board can also perform a load-bearing function. For example, the rigid circuit board can stably support the aforementioned electronic components and chips. The rigid circuit board can also be inserted into the electrical connector in the cage 106 of the host computer 100.

[0104] The circuit board 300 also includes gold fingers formed on its end surfaces, each gold finger consisting of a plurality of independent pins. The circuit board 300 is inserted into a cage 106 and is electrically connected to an electrical connector within the cage 106 by the gold fingers. The gold fingers may be located only on one side of the surface of the circuit board 300 (e.g., ...). Figure 4 The upper surface shown can also be positioned on the upper and lower surfaces of the circuit board 300 to provide a greater number of pins, thus adapting to applications with high pin count requirements. The gold fingers are 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, and data signal transmission. Of course, flexible circuit boards are also used in some optical modules. Flexible circuit boards are generally used in conjunction with rigid circuit boards as a supplement to rigid circuit boards.

[0105] At least one of the light emitting component 400 or the light receiving component 500 is located on the side of the circuit board 300 away from the gold fingers.

[0106] In some embodiments, the light emitting component 400 and the light receiving component 500 are physically separated from the circuit board 300, and then electrically connected to the circuit board 300 through corresponding flexible circuit boards or electrical connectors.

[0107] In some embodiments, at least one of the light emitting component 400 or the light receiving component 500 may be directly disposed on the circuit board 300. For example, at least one of the light emitting component 400 or the light receiving component 500 may be disposed on the surface of the circuit board 300 or the side of the circuit board 300.

[0108] In some embodiments, the optical module further includes a first housing 510. A first end of the first housing 510 may be connected to the light emitting component 400, and a second end of the first housing 510 may be connected to the light receiving component 500.

[0109] like Figure 4 As shown, in some embodiments, an optical fiber adapter 700 may be disposed inside the housing of the optical module 200. One end of the optical fiber adapter 700 may be connected to the third end of the first housing 510 so that the received optical signal from the outside is input to the first housing 510 through the optical fiber adapter 700, and then forwarded to the optical receiving component 500 by the optical components of the first housing 510.

[0110] The first end of the first housing 510 can be connected to the optical transmitting component 400, the second end of the first housing 510 can be connected to the optical receiving component 500, and the third end of the first housing 510 can be connected to one end of the fiber optic adapter 700, so that the transmitted optical signal emitted by the optical transmitting component 400 is first transmitted to the first housing 510, then transmitted through the first housing 510 to the fiber optic adapter 700, and finally output through the fiber optic adapter 700. The optical receiving component 500 and the optical transmitting component 400 share the fiber optic adapter 700, and thus the uplink and downlink optical signals of the optical module share the same optical fiber 101.

[0111] In some embodiments, the light emitting component 400 and the circuit board 300 can be connected via a flexible circuit board.

[0112] In some embodiments, the light receiving component 500 and the circuit board 300 can be connected via a flexible circuit board.

[0113] In some embodiments, the first end of the first housing 510 and the second end of the first housing 510 may be disposed opposite to each other, and the third end of the first housing 510 and the first end of the first housing 510 may be disposed adjacent to each other, so that the fiber optic adapter 700 and the optical receiving component 500 are both offset from the middle of the housing, thereby causing the optical port to be offset from the middle of the housing.

[0114] Figure 5a A structure of an upper housing according to some embodiments. Figure 1 . Figure 5b A structure of an upper housing according to some embodiments. Figure 2 .like Figure 5a and Figure 5bAs shown, in some embodiments, the upper housing 201 can include a cover plate 2011, and two upper side plates 2012 located on both sides of the cover plate 2011 and arranged perpendicularly to the cover plate 2011. The upper side plates 2012 can be provided with accommodating grooves 2121. The accommodating grooves 2121 are recessed inwardly relative to the upper side plates 2012, so that the accommodating grooves 2121 can accommodate part of the unlocking device of the unlocking component 600.

[0115] In some embodiments, the upper housing 201 can include a light interface piece 2013. The light interface piece 2013 is away from the gold fingers of the circuit board 300. The light interface piece 2013 can be provided with a receptacle 2144. The receptacle 2144 can pass through the light interface piece 2013 to communicate the inside and outside of the optical module, so that the optical fiber 101 can be connected to the other end of the optical fiber adapter 700 through the receptacle 2144, and then the optical fiber 101 and the optical module 200 can interact with each other.

[0116] In some embodiments, the light interface piece 2013 can be connected with the cover plate 2011 and the two upper side plates 2012, so that the upper housing 201 is an integral structure.

[0117] In some embodiments, the light interface piece 2013 can be welded with the cover plate 2011 and the two upper side plates 2012.

[0118] In some embodiments, the light interface piece 2013 can include a first cover plate portion 2131, one end of which can be connected with the cover plate 2011.

[0119] The light interface piece 2013 can include a second cover plate portion 2132, one end of which can be connected with the other end of the first cover plate portion 2131.

[0120] In some embodiments, the second cover plate portion 2132 can be recessed inwardly relative to the first cover plate portion 2131, so as to facilitate placing part of the unlocking handle of the unlocking component 600 on the second cover plate portion 2132.

[0121] In some embodiments, the top surface of the second cover plate portion 2132 is an inclined surface, and the end of the second cover plate portion 2132 connected with the first cover plate portion 2131 is more recessed relative to the other end of the second cover plate portion 2132 away from the first cover plate portion 2131. This not only helps the unlocking handle to smoothly slide into the lower part of the second cover plate portion 2132, but also provides a guiding effect during the unlocking process, ensuring that the unlocking handle can accurately cooperate with other parts of the unlocking component 600, thereby realizing stable locking and convenient unlocking of the optical module 200.

[0122] In some embodiments, the optical interface 2013 can include a second side plate portion 2133. A first end of the second side plate portion 2133 can be connected with the first upper side plate 2012.

[0123] In some embodiments, a second end of the second side plate portion 2133 can form a first clamping groove 2136. The first clamping groove 2136 can be formed by inwardly recessing a side of the second side plate portion 2133. An open edge of the first clamping groove 2136 can be in communication with the second end face of the second side plate portion 2133, so that an external clamping element can be smoothly clamped into the first clamping groove 2136, achieving stable connection of the optical module 200 with other devices. At the same time, the design of the first clamping groove 2136 can also provide a certain elastic clamping force, so that the optical module 200 is not easy to fall off after connection, ensuring the stability and reliability of the connection.

[0124] In some embodiments, the second end of the second side plate portion 2133 can form a first storage groove 2137. The first storage groove 2137 can be formed by inwardly recessing the second end of the second side plate portion 2133. An open edge of the first storage groove 2137 can be in communication with the second end face of the second side plate portion 2133, so that the first storage groove 2137 can accommodate some auxiliary elements or lines, which helps to optimize the space layout inside the optical module 200 and improve the overall compactness and tidiness. At the same time, the open edge of the first storage groove 2137 is in communication with the second end face of the second side plate portion 2133, which facilitates technicians to easily access and operate the elements placed in the first storage groove 2137 from the side of the optical module 200 during installation or maintenance, improving the convenience and efficiency of operation.

[0125] The other open edge of the first storage groove 2137 can be in communication with the bottom of the second side plate portion 2133, which can effectively prevent the elements or lines placed therein from being accidentally compressed or damaged by the cover plate, enhancing the safety and stability of the optical module 200.

[0126] The first storage groove 2137 can form a first limiting face 21371. The first limiting face 21371 can be oppositely arranged with the second end face of the second side plate portion 2133. The bottom of the first limiting face 21371 can be in communication with the bottom of the second side plate portion 2133. The first limiting face 21371 can be perpendicularly arranged with the bottom of the second side plate portion 2133.

[0127] The first storage groove 2137 can form a second limiting face 21372. The second limiting face 21372 is oppositely arranged with the second end face of the second side plate portion 2133. The bottom of the second limiting face 21372 can be connected with the top of the first limiting face 21371. The second limiting face 21372 can be an arc face.

[0128] In some embodiments, the first limiting surface 21371 protrudes from the second limiting surface 21372, so that the first limiting surface 21371 can be tangent to the limiting protrusion of the unlocking handle, and the second limiting surface 21372 is not tangent to the limiting protrusion of the unlocking handle.

[0129] In some embodiments, the first clamping groove 2136 and the first storage groove 2137 are not connected, so as to avoid interference between the clamping element in the first clamping groove 2136 and the element or circuit in the first storage groove 2137, and ensure the independence and stability of the respective functions.

[0130] In some embodiments, the optical interface piece 2013 can include a first side plate portion 2134. The first end of the first side plate portion 2134 can be connected to the other upper side plate 2012.

[0131] In some embodiments, the second end of the first side plate portion 2134 can form the first clamping groove 2136. The first clamping groove 2136 can be formed by the first side plate portion 2134 being inwardly recessed.

[0132] In some embodiments, the second end of the first side plate portion 2134 can form the first storage groove 2137. The first storage groove 2137 can be formed by the first side plate portion 2134 being inwardly recessed.

[0133] In some embodiments, the width dimension d1 of the first side plate portion 2134 is greater than the width dimension d2 of the second side plate portion 2133, so that the optical port between the first side plate portion 2134 and the first side plate portion 2133 is offset from the middle of the shell, while ensuring the structural strength of the shell.

[0134] Since the width dimension d1 of the first side plate portion 2134 is greater than the width dimension d2 of the second side plate portion 2133, it is not convenient to form a third storage groove 2139 for placing an elastic return element in the second side plate portion 2133, therefore, in some embodiments, the second end of the first side plate portion 2134 can form the third storage groove 2139. The third storage groove 2139 can be used to place an elastic return element. The third storage groove 2139 can be located between the first clamping groove 2136 and the first storage groove 2137, and can effectively utilize the space of the first side plate portion 2134.

[0135] In some embodiments, the cross section of the third storage groove 2139 is arc-shaped, so as to reduce the friction between the elastic return element and the third storage groove 2139, and facilitate the compression or stretching of the elastic return element in the third storage groove 2139.

[0136] In some embodiments, an opening edge of the third storage groove 2139 can be in communication with the side surface of the first side plate portion 2134, so as to facilitate the insertion of the first clamping protrusion of the unlocking component 600 and the connection with one end of the elastic return element.

[0137] An opening edge of the third storage groove 2139 is connected with the side surface of the first side plate part 2134, and the opening is a first opening. In some embodiments, the size of the first opening of the third storage groove 2139 is smaller than the diameter of the elastic return member, so that the elastic return member can be stably retained in the third storage groove 2139 after installation and will not accidentally fall off during use of the optical module.

[0138] In some embodiments, another opening of the third storage groove 2139 can be connected with the second end surface of the first side plate part 2134 to facilitate installation and removal of the elastic return member. When the elastic return member is installed, one end of the elastic return member can be pushed into the third storage groove 2139 through the opening until the other end of the elastic return member is connected with the first clamping protrusion of the unlocking component 600. When the elastic return member needs to be removed, it can also be conveniently taken out of the third storage groove 2139 through the opening without disassembling the entire optical module, improving the convenience of maintenance.

[0139] Another opening edge of the third storage groove 2139 is connected with the second end surface of the first side plate part 2134, and the opening is a second opening. In some embodiments, the first opening of the third storage groove 2139 and the second opening of the third storage groove 2139 can be connected to facilitate smooth movement of the elastic return member in the third storage groove 2139. This design not only simplifies the installation and removal process of the elastic return member, but also ensures its stability and reliability during use of the optical module.

[0140] In some embodiments, the second end of the first side plate part 2134 can form a second storage groove 2138. The second storage groove 2138 can be connected with one end of the third storage groove 2139, so that the elastic return member can enter the third storage groove 2139 from the second storage groove 2138. The second storage groove 2138 can place a fixing member, so that the elastic return member installed in the third storage groove 2139 is connected with the fixing member.

[0141] The second storage groove 2138 can be formed by inwardly recessing the second end surface of the first side plate part 2134, so that the opening edge of the second storage groove 2138 can be connected with the second end surface of the first side plate part 2134 to facilitate installation and maintenance of the fixing member in the second storage groove 2138 and the elastic return member in the third storage groove 2139.

[0142] In some embodiments, the second storage groove 2138 can be connected with the first storage groove 2137, and the second storage groove 2138 can be connected with the first clamping groove 2136 to reduce the height size of the first side plate part 2134, and in turn reduce the height size of the entire optical module.

[0143] Since the first opening of the third storage groove 2139 is communicated with the second opening of the third storage groove 2139, and the second storage groove 2138 is communicated with the third storage groove 2139, the second storage groove 2138 can form an opening, the edge of which is communicated with the side of the first side plate part 2134, so as to facilitate the installation and maintenance of the elastic reset member.

[0144] Figure 5c A structure of an upper shell according to some embodiments Figure 3 . Figure 6 A structure diagram of a lower shell according to some embodiments. Figure 7 A structure diagram of a shell according to some embodiments. As shown in Figure 5c 、 Figure 6 and Figure 7 In some embodiments, the optical interface piece 213 can include a bottom plate part 2135. One side of the bottom plate part 2135 can be connected with the second side plate part 2133, and the other side of the bottom plate part 2135 can be connected with the first side plate part 2134, so that the optical interface piece 213 can form a jack 2144.

[0145] In some embodiments, the side of the first side plate part 2134 away from the first cover plate part 2131 can form a clamping surface 2140.

[0146] In some embodiments, the second side plate part 2133 can form a clamping surface 2140. The clamping surface 2140 can be connected with the bottom plate part 2135. The clamping surface 2140 is more recessed relative to the bottom plate part 2135 to form a clamping space. The clamping space can be configured to accommodate an optical fiber or other connecting element to ensure a stable connection between the optical module and an external device.

[0147] In some embodiments, the side of the first side plate part 2134 away from the first cover plate part 2131 can form a protruding part 2141.

[0148] In some embodiments, the second side plate part 2133 can form a protruding part 2141. The protruding part 2141 can protrude outward relative to the clamping surface 2140. One side of the protruding part 2141 can be connected with the clamping surface 2140. The protruding part 2141 can protrude outward relative to the clamping surface 2140, and one side of the protruding part 2141 can be connected with the clamping surface 2140, so that the second side plate part 2133 can form an L-shaped slot.

[0149] In some embodiments, the protruding part 2141 and the bottom plate part 2135 partially overlap in the length direction of the upper shell 201, and the overlapping area is a U-shaped second clamping slot 2142, which not only plays a positioning role, but also increases the firmness of the connection through clamping.

[0150] In some embodiments, the bottom plate 2021 of the lower housing 202 can include a first clamping portion 2211. One end of the first clamping portion 2211 can be connected with the bottom plate portion 2135. One side of the first clamping portion 2211 can be arranged in correspondence with the protruding portion 2141, so that the first clamping portion 2211, the clamping surface 2140 and the protruding portion 2141 can form a third clamping groove 2143, which not only can play a positioning role, but also can increase the firmness of the connection through clamping.

[0151] In some embodiments, the bottom plate 2021 can include a second clamping portion 2212. One end of the second clamping portion 2212 can be connected with the other end of the first clamping portion 2211.

[0152] The width dimension d3 of the first clamping portion 2211 can be smaller than the width dimension d4 of the second clamping portion 2212, so that the bottom plate 2021 can be clamped between the protruding portion 2141 of the second side plate portion 2133 and the protruding portion 2141 of the first side plate portion 2134.

[0153] Figure 8a A partial structure of a light module according to some embodiments Figure 1 . A partial structure of a light module according to some embodiments Figure 8b A partial structure of a light module according to some embodiments Figure 9 A partial structure of a light module according to some embodiments Figure 2 . As Figure 8a , Figure 8b and Figure 9 shown in some embodiments, the unlocking component 600 can include an unlocking handle 610 and an unlocker 620. The unlocking handle 610 is fixedly connected with the unlocker 620, so that the unlocker 620 can move with the movement of the unlocking handle 610.

[0154] The unlocker 620 can include an elastic reset member 630, one end of the elastic reset member 630 can be connected with the unlocker 620, so that the unlocker 620 can extrude the elastic reset member 630 under the action of external force, and the elastic reset member 630 can reset and push the unlocker 620 to move under the action of no external force. For example, the elastic reset member 630 can be a spring.

[0155] When the user needs to unlock the light module, the external force acts on the unlocking handle 610 to make the unlocking handle 610 rotate or move, and the unlocker 620 moves with the unlocking handle 610, thereby releasing the fixation of the light module with the host computer, that is, achieving unlocking. When the external force disappears, the elastic reset member 630 resets and pushes the unlocker 620 to move, thereby achieving the fixation of the light module with the host computer, that is, achieving locking.

[0156] In some embodiments, the light module can include a fixing member 203. The fixing member 203 can be fixedly connected with one end of the elastic reset member 630 to limit the movement range of the elastic reset member 630 and prevent it from moving excessively or deviating from the predetermined position uncontrollably. The fixing member 203 can be a screw or a buckle structure.

[0157] In some embodiments, the fixing member 203 can be arranged in the second storage groove 2138.

[0158] In some embodiments, the fixing member 203 can be arranged in the second storage groove 2138 and the third storage groove 2139.

[0159] In some embodiments, the fixing member 203 can include a first fixing part 231. The first fixing part 231 can be arranged in the second storage groove 2138 to achieve the connection of the fixing member 203 with the upper shell 201.

[0160] The fixing member 203 can include a second fixing part 232. One end of the second fixing part 232 can be connected with the first fixing part 231. The second fixing part 232 can be arranged in the third storage groove 2139 to further achieve the connection of the fixing member 203 with the upper shell 201 and improve the connection stability.

[0161] The second fixing part 232 and the first fixing part 231 can be an integrally formed structure or can be connected by welding.

[0162] In some embodiments, the size of the first fixing part 231 is greater than the size of the second fixing part 232, and the size of the third storage groove 2139 is smaller than the size of the second storage groove 2138, so that the first fixing part 231 can be stopped in the second storage groove 2138 and cannot enter the third storage groove 2139, thereby limiting the position of the fixing member 203 in the third storage groove 2139.

[0163] Figure 10 A partial view of a unlocking component according to some embodiments. Figure 11 A partial structure of a light module according to some embodiments Figure 3 . Figure 12 A structure of a light module according to some embodiments Figure 2 . As shown in Figure 10 and Figure 11 , in some embodiments, the unlocking handle 610 can include a holding part 611 and two connecting parts 612 connected with the two sides of the holding part 611 respectively, so that the shape of the unlocking handle 610 is U-shaped, which is convenient for users to hold and operate. When the user needs to unlock or operate the light module, the force can be applied through the holding part 611, and the force is transmitted through the connecting part 612, so as to achieve the unlocking or operation of the light module.

[0164] In some embodiments, the inwardly recessed connecting portion 612 can form a first insertion hole 613.

[0165] In some embodiments, the unlocking handle 610 can include a rotating shaft 615. The rotating shaft 615 can be inserted into the first insertion hole 613, so that the unlocking handle 610 can rotate along the rotating shaft 615.

[0166] In some embodiments, the rotating shaft 615 can pass through the first insertion hole 613, so that the rotating shaft 615 can not only be inserted into the unlocking handle 610, but also be inserted into the unlocking device 620, so that the unlocking device 620 is connected with the unlocking handle 610.

[0167] In some embodiments, the outwardly protruding end of the connecting portion 612 away from the holding portion 611 can form a limiting protrusion 614. The limiting protrusion 614 can rotate with the rotation of the unlocking handle 610. When the unlocking handle 610 rotates clockwise along the rotating shaft 615, the limiting protrusion 614 also rotates clockwise along the rotating shaft 615. The limiting protrusion 614 can be tangent to the first limiting surface 21371, and when the limiting protrusion 614 rotates clockwise, the first limiting surface 21371 can provide an opposite thrust to the limiting protrusion 614, which pushes the unlocking handle 610 to move in a first direction, and the unlocking handle 610 drives the unlocking device 620 to move in the first direction, thereby achieving the unlocking of the optical module.

[0168] In some embodiments, the unlocking device 620 can include a connecting arm 621, a second clamping arm 622, and a first clamping arm 623. One end of the second clamping arm 622 can be connected with one side of the connecting arm 621, and one end of the first clamping arm 623 can be connected with the other side of the connecting arm 621, so that the shape of the unlocking device 620 is similar to H shape.

[0169] In some embodiments, the first end of the second clamping arm 622 can form a second clamping protrusion 624. The second clamping protrusion 624 protrudes outwardly relative to the inner surface of the second clamping arm 622. The second clamping protrusion 624 can be correspondingly arranged with the first clamping groove 2136. The second clamping protrusion 624 is in contact with the first clamping groove 2136, and the second clamping protrusion 624 cannot move in the height direction of the upper shell 201, which not only can limit the position of the second clamping arm 622 in the height direction of the upper shell, but also can increase the contact area between the second clamping arm 622 and the upper shell, thereby improving the connection stability between the second clamping arm 622 and the upper shell.

[0170] In some embodiments, the first end of the second clamping arm 622 can form a second insertion hole 625. The second insertion hole 625 can be arranged corresponding to the first insertion hole 613. The rotation shaft 615 can pass through the first insertion hole 614 and cross the second insertion hole 625, so that the unlocking handle 610 is connected with the unlocker 620, so that the sliding of the unlocking handle 610 can drive the sliding of the unlocker 620.

[0171] In some embodiments, the first end of the second clamping arm 622 can form a sliding hole 626. The sliding hole 626 can be arranged corresponding to the limiting protrusion 614. The limiting protrusion 614 can pass through the sliding hole 626, and the rotation track of the limiting protrusion 614 can match the contour of the sliding hole 626, so that the limiting protrusion 614 can rotate in the sliding hole 626. The limiting protrusion 614 can be tangent to the first limiting surface 21371, and when the limiting protrusion 614 rotates clockwise, the first limiting surface 21371 can provide a reverse thrust to the limiting protrusion 614, which drives the unlocking handle 610 to move in the first direction, and the unlocking handle 610 drives the unlocker 620 to move in the first direction, thereby achieving the unlocking of the optical module.

[0172] In some embodiments, the sliding hole 626 is arc-shaped, and the distance between each point on the side of the sliding hole 626 close to the second insertion hole 625 and the center point of the second insertion hole 625 is equal, which can keep the relative position between the limiting protrusion 614 and the second insertion hole 625 stable when the limiting protrusion 614 slides in the sliding hole 626, and ensure the smooth and stable connection between the unlocking handle 610 and the unlocker 620.

[0173] In some embodiments, the angle of the sliding hole 626 is 90°, so that the limiting protrusion 614 is located at the bottom end of the sliding hole 626 before the optical module is unlocked, and the limiting protrusion 614 is located at the top end of the sliding hole 626 after the optical module is unlocked.

[0174] In some embodiments, the vertical distance between the first end of the second clamping arm 622 and the bottom of the second clamping arm 622 in the sliding hole 626 close to the first end of the second clamping arm 622 is equal to the vertical distance between the first end of the second clamping arm 622 and the bottom of the second clamping arm 622 in the sliding hole 626 away from the first end of the second clamping arm 622.

[0175] In some embodiments, the vertical distance between the first end of the second clamping arm 622 and the bottom of the second clamping arm 622 in the sliding hole 626 is less than the vertical distance between the first end of the second clamping arm 622 and the bottom of the second clamping arm 622 away from the sliding hole 626, so that the limiting protrusion 614 at the bottom end of the sliding hole 626 can be tangent to the first limiting surface 21371, and the limiting protrusion 614 at the top end of the sliding hole 626 can be tangent to the third limiting surface of the first storage groove 2137, wherein the third limiting surface of the first storage groove 2137 can be connected to the top of the second limiting surface 21372, and the third limiting surface of the first storage groove 2137 can be perpendicular to the first limiting surface 21371.

[0176] In some embodiments, the first end of the second clamping arm 622 can be curved to form a clamping portion 627. The clamping portion 627 can include a first sub-clamping portion 6271. The first sub-clamping portion 6271 can be connected to the clamping arm body of the second clamping arm 622. The first sub-clamping portion 6271 can be connected to the top surface of the protruding portion 2141.

[0177] The clamping portion 627 can include a second sub-clamping portion 6272. One end of the second sub-clamping portion 6272 can be connected to the other end of the first sub-clamping portion 6271, and the second sub-clamping portion 6272 is a free end.
