DETAILED DESCRIPTION

[0048] Some embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. However, the described embodiments are only a part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments provided by the present disclosure, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of the present disclosure.

[0049] Unless the context requires otherwise, throughout the specification and claims, the term "comprising" is to be interpreted as having an open, inclusive meaning, 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" implies open and inclusive language, which does not exclude devices that are suitable for or configured to perform additional tasks or steps; descriptions such as "parallel", "perpendicular", "same", "consistent", and "flush" are not limited to absolute mathematical theoretical relationships, but also include an acceptable error range generated in practice, and also include differences based on the same design concept but due to manufacturing reasons.

[0050] In optical communication technology, in order to establish information transmission between information processing devices, it is necessary to load information onto light and use the propagation of light to achieve information transmission. Here, the light loaded with information is an optical signal. When optical signals are transmitted in information transmission equipment, the loss of optical power can be reduced, so high-speed, long-distance, and low-cost information transmission can be achieved. The signals that information processing equipment can recognize and process are electrical signals. Information processing equipment usually includes optical network terminals (Optical Network Unit, ONU), gateways, routers, switches, mobile phones, computers, servers, tablets, televisions, etc., and information transmission equipment usually includes optical fibers and optical waveguides.

[0051] The optical module can realize the mutual conversion between optical signals and electrical signals between information processing equipment and information transmission equipment. For example, at least one of the optical signal input end or the optical signal output end of the optical module is connected to an optical fiber, and at least one of the electrical signal input end or the electrical signal output end of the optical module is connected to an optical network terminal; the first optical signal from the optical fiber is transmitted to the optical module, and the optical module converts the first optical signal into a first electrical signal, and transmits the first electrical signal to the optical network terminal; the second electrical signal from the optical network terminal is transmitted to the optical module, and the optical module converts the second electrical signal into a second optical signal, and transmits the second optical signal to the optical fiber. Since multiple information processing devices can transmit information through electrical signals, at least one of the multiple information processing devices needs to be directly connected to the optical module, and all information processing devices do not need to be directly connected to the optical module. Here, the information processing device directly connected to the optical module is called the upper computer of the optical module. In addition, the optical signal input end or the optical signal output end of the optical module can be called an optical port, and the electrical signal input end or the electrical signal output end of the optical module can be called an electrical port.

[0052] Figure 1 FIG. 1 is a partial structural diagram of an optical communication system according to some embodiments. Figure 1 As shown, the optical communication system mainly includes a remote information processing device 1000 , a local information processing device 2000 , a host computer 100 , an optical module 200 , an optical fiber 101 and a network cable 103 .

[0053] One end of the optical fiber 101 extends toward the remote information processing device 1000, and the other end of the optical fiber 101 is connected to the optical module 200 through the optical port of the optical module 200. The optical signal can be totally reflected in the optical fiber 101, and the propagation of the optical signal in the total reflection direction can almost maintain the original optical power. The optical signal undergoes multiple total reflections in the optical fiber 101 to transmit the optical signal from the remote information processing device 1000 to the optical module 200, or to transmit the optical signal from the optical module 200 to the remote information processing device 1000, thereby realizing long-distance, low-power loss information transmission.

[0054] The optical communication system may include one or more optical fibers 101, and the optical fibers 101 are detachably connected or fixedly connected to the optical module 200. The host computer 100 is configured to provide data signals to the optical module 200, receive data signals from the optical module 200, or monitor or control the working state of the optical module 200.

[0055] The host computer 100 includes a substantially rectangular housing and an optical module interface 102 disposed on the housing. The optical module interface 102 is configured to connect to the optical module 200 so that the host computer 100 and the optical module 200 establish a unidirectional or bidirectional electrical signal connection.

[0056] The host computer 100 also includes an external electrical interface, which can be connected to an electrical signal network. For example, the external electrical interface includes a Universal Serial Bus (USB) interface or a network cable interface 104, and the network cable interface 104 is configured to access the network cable 103 so that the host computer 100 establishes a unidirectional or bidirectional electrical signal connection with the network cable 103. One end of the network cable 103 is connected to the local information processing device 2000, and the other end of the network cable 103 is connected to the host computer 100, so as to establish an electrical signal connection between the local information processing device 2000 and the host computer 100 through the network cable 103. For example, the third electrical signal sent by the local information processing device 2000 is transmitted to the host computer 100 through the network cable 103, and the host computer 100 generates a second electrical signal according to the third electrical signal. The second electrical signal from the host computer 100 is transmitted to the optical module 200, and the optical module 200 converts the second electrical signal into a second optical signal, and transmits the second optical signal to the optical fiber 101, and the second optical signal is transmitted to the remote server 1000 in the optical fiber 101. For example, the first optical signal from the remote information processing device 1000 is transmitted through the optical fiber 101, and the first optical signal from the optical fiber 101 is transmitted to the optical module 200, and the optical module 200 converts the first optical signal into a first electrical signal, and the optical module 200 transmits the first electrical signal to the host computer 100, and the host computer 100 generates a fourth electrical signal according to the first electrical signal, and transmits the fourth electrical signal to the local information processing device 2000. It should be noted that the optical module is a tool for realizing the mutual conversion between optical signals and electrical signals. During the conversion process between the optical signals and electrical signals, the information does not change, but the encoding and decoding methods of the information can change.

[0057] 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.

[0058] Figure 2 FIG. 1 is a partial structural diagram of a host computer according to some embodiments. In order to clearly show the connection relationship between the optical module 200 and the host computer 100, Figure 2 Only the structure of the host computer 100 related to the optical module 200 is shown. Figure 2 As shown, the host computer 100 further includes a PCB circuit board 105 disposed in the housing, a cage 106 disposed on the surface of the PCB circuit board 105, a heat sink 107 disposed on the cage 106, and an electrical connector disposed inside the cage 106. The electrical connector is configured to access the electrical port of the optical module 200; the heat sink 107 has a protruding structure such as fins to increase the heat dissipation area.

[0059] The optical module 200 is inserted into the cage 106 of the host computer 100, and the cage 106 fixes the optical module 200. The heat generated by the optical module 200 is transferred to the cage 106 and then diffused through the heat sink 107. After the optical module 200 is inserted into the cage 106, the electrical port of the optical module 200 is connected to the electrical connector inside the cage 106, so that the optical module 200 establishes a bidirectional electrical signal connection with the host computer 100. In addition, the optical port of the optical module 200 is connected to the optical fiber 101, so that the optical module 200 establishes a bidirectional optical signal connection with the optical fiber 101.

[0060] Figure 3 is a structural diagram of an optical module according to some embodiments, Figure 4 FIG. 1 is an exploded view of an optical module according to some embodiments. Figure 3 and Figure 4 As shown, the optical module 200 includes a shell, a circuit board 300 disposed in the shell, a light emitting component 400 and a light receiving component 500. However, the present disclosure is not limited thereto. In some embodiments, the optical module 200 includes one of the light emitting component 400 and the light receiving component 500.

[0061] The housing comprises 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 body.

[0062] In some embodiments, the lower shell 202 includes a bottom plate 2021 and two lower side plates 2022 located on both sides of the bottom plate 2021 and arranged perpendicular to the bottom 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.

[0063] In some embodiments, the lower shell 202 includes a bottom plate 2021 and two lower side plates 2022 located on both sides of the bottom plate 2021 and vertically arranged with the bottom 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 vertically arranged with the cover plate 2011, and the two upper side plates are combined with the two lower side plates 2022 to realize that the upper shell 201 covers the lower shell 202.

[0064] The direction of the line connecting the two openings 204 and 205 may be consistent with the length direction of the optical module 200, or may be inconsistent with the length direction of the optical module 200. For example, the opening 204 is located at the end of the optical module 200 ( Figure 3 The opening 205 is also located at the end of the optical module 200 ( Figure 3Alternatively, 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 finger 301 of the circuit board 300 extends from the electrical port and is inserted into the electrical connector of the host computer 100; the opening 205 is an optical port, which is configured to access the external optical fiber 101, so that the optical fiber 101 connects the optical emitting component 400 and the optical receiving component 500 in the optical module 200.

[0065] The assembly method of combining the upper shell 201 and the lower shell 202 is adopted, which facilitates the installation of the circuit board 300, the light emitting component 400, the light receiving component 500, etc. into the above shell, and the upper shell 201 and the lower shell 202 can encapsulate and protect the above components. In addition, when assembling the circuit board 300, the light emitting component 400 and the light receiving component 500, etc., it is convenient to deploy the positioning components, heat dissipation components and electromagnetic shielding components of these components, which is conducive to the automated production.

[0066] In some embodiments, the upper shell 201 and the lower shell 202 are made of metal materials to facilitate electromagnetic shielding and heat dissipation.

[0067] 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.

[0068] For example, the unlocking component 600 is located on the outside of the two lower side plates 2022 of the lower housing 202, and includes a snap-fit ​​component that matches 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 fixes 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 relationship between the snap-fit ​​component and the host computer, so as to release the fixation of the optical module 200 and the host computer, so that the optical module 200 can be pulled out of the cage 106.

[0069] The circuit board 300 includes circuit traces, electronic components and chips, etc. The electronic components and chips are connected according to the circuit design through the circuit traces to realize the functions of power supply, electrical signal transmission and grounding. The electronic components may include capacitors, resistors, transistors, metal-oxide-semiconductor field-effect transistors (Metal-Oxide-Semiconductor Field-Effect Transistor, MOSFET), etc. The chips may include microcontroller units (Microcontroller Unit, MCU), laser driver chips, transimpedance amplifiers (Transimpedance Amplifier, TIA), limiting amplifiers (Limiting Amplifier, LIA), clock and data recovery chips (Clock and Data Recovery, CDR), power management chips, and digital signal processing (Digital Signal Processing, DSP) chips.

[0070] The circuit board 300 is generally a rigid circuit board. Due to its relatively hard material, the rigid circuit board can also realize the load-bearing function. For example, the rigid circuit board can stably carry the above-mentioned 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.

[0071] The circuit board 300 also includes a gold finger 301 formed on the end surface thereof. The gold finger 301 is composed of a plurality of independent pins. The circuit board 300 is inserted into the cage 106, and the gold finger 301 is connected to the electrical connector in the cage 106. The gold finger 301 can be provided on only one side of the circuit board 300 (e.g. Figure 4 The upper surface shown in the figure) can also be set on the upper and lower surfaces of the circuit board 300 to provide more pins, so as to adapt to occasions where the number of pins is large. The gold finger 301 is configured to establish an electrical connection with the host computer to achieve power supply, grounding, two-wire synchronous serial (Inter-Integrated Circuit, I2C) signal transmission, data signal transmission, etc. Of course, flexible circuit boards are also used in some optical modules. Flexible circuit boards are generally used in conjunction with rigid circuit boards to supplement rigid circuit boards.

[0072] At least one of the light emitting component 400 or the light receiving component 500 is located on a side of the circuit board 300 away from the gold finger 301 .

[0073] 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.

[0074] In some embodiments, at least one of the light emitting component or the light receiving component may be directly disposed on the circuit board 300. For example, at least one of the light emitting component or the light receiving component may be disposed on a surface of the circuit board 300 or a side of the circuit board 300.

[0075] Figure 5 This is a schematic diagram of the structure of the housing and the unlocking component in the optical module provided according to some embodiments of the present application. Figure 6 This is a front view of the cooperation between the housing and the unlocking component in the optical module provided according to some embodiments of the present application.

[0076] For some examples, refer to Figure 5 and Figure 6 As shown, the optical module may include a housing 200 .

[0077] In some examples, the housing 200 may include the upper housing 200 and the lower housing 200 described in the previous embodiments of the present application. The upper housing 200 and the lower housing 200 are covered to form a cavity.

[0078] In some examples, the circuit board and the optical transceiver component may be disposed in the cavity.

[0079] In some examples, to facilitate the removal of the optical module from the host computer, the optical module may include an unlocking component 600. The unlocking component 600 may be located on both sides of the housing 200. The unlocking component 600 may be the unlocking component 600 described in the foregoing embodiment of the present application.

[0080] In some examples, the unlocking component 600 may include a locking tongue 601. The locking tongue 601 may be movably disposed on the housing 200.

[0081] In some examples, the locking tongue 601 may be disposed at the optical port end of the optical module housing 200 .

[0082] In some examples, the locking tongue 601 may have a locked state. In the locked state, the locking tongue 601 may extend out of the housing 200 so that the locking tongue 601 cooperates with the locking spring of the upper computer cage.

[0083] In some examples, when the optical module is inserted into the host computer cage and the locking tongue 601 is in a locking state of locking the optical module and the host computer, the locking tongue 601 may be located on a side of the locking spring facing away from the optical port.

[0084] In some examples, the locking tongue 601 can cooperate with the locking spring to prevent the optical module from being pulled out of the host computer cage, thereby locking the optical module and the host computer.

[0085] In some examples, a spring sheet may be provided at the optical port end of the housing 200. The locking tongue 601 may include a protruding portion protruding from the spring sheet.

[0086] In some examples, when the optical module is inserted into the cage of the host computer, the locking tongue 601 can extend out of the housing 200 under the elastic force of the spring sheet, thereby cooperating with the locking spring sheet of the cage of the host computer.

[0087] In some examples, a force providing member (not shown) may be disposed in the housing 200. The force providing member may provide a force for the locking tongue 601 to move toward the outside of the housing 200.

[0088] In some examples, the force provider may include a spring.

[0089] In some examples, the force providing member may include a magnetic member. The magnetic member may be two magnets with opposite polarities. One of the magnets is disposed on the housing 200, and the other magnet is disposed on the lock tongue 601. The lock tongue 601 moves toward the outside of the housing 200 through the repulsive force between the two magnets.

[0090] In some examples, the locking tongue 601 can have an unlocked state.

[0091] In some examples, in the unlocked state, the lock tongue 601 can be retracted into the housing 200, thereby releasing the lock between the optical module and the host computer.

[0092] In some examples, in order to switch the lock tongue 601 from the locked state to the unlocked state, the lock tongue 601 may be provided with a force that overcomes the force provided by the force providing member.

[0093] In some examples, the optical module may include a rotating handle 602. The rotating handle 602 may be rotatably connected to the housing 200.

[0094] In some examples, when the rotating handle 602 rotates relative to the housing 200, the rotating handle 602 can apply a force to the lock tongue 601, so that the lock tongue 601 overcomes the force provided by the force providing member and moves into the housing 200; thereby, the lock tongue 601 switches from a locked state to an unlocked state.

[0095] For some examples, refer to Figure 6 As shown, when the handle 602 is rotated relative to the housing 200, Figure 6 When rotating in the direction indicated by the arrow a, the locking tongue 601 can rotate along the Figure 6 The housing 200 moves in the direction indicated by the arrow b and retracts into the housing 200 .

[0096] In some examples, after the optical module is produced, it is necessary to test whether the lock tongue 601 can be normally retracted into the housing 200 under the action of the rotating handle 602. That is, it is necessary to test whether the optical module can be normally unlocked with the host computer cage to ensure that the optical module can be normally unlocked with the host computer cage after matching with the host computer cage.

[0097] Figure 7 This is a structural schematic diagram of an optical module unlocking function detection mechanism provided according to some embodiments of the present application.

[0098] To check whether the unlocking function of the optical module is normal, refer to Figure 7 As shown, in some examples of the embodiments of the present application, an optical module unlocking function detection mechanism 800 is provided. The detection mechanism 800 may include a clamping component 810.

[0099] In some examples, the clamping component 810 may be configured to clamp and fix the optical module.

[0100] In some examples, the clamping component 810 may be configured to clamp and fix a housing of the optical module.

[0101] In some examples, the clamping member 810 may include a positioning member 811. The upper surface of the positioning member 811 may have a positioning groove 8111. The optical module may be placed in the positioning groove 8111.

[0102] In some examples, the positioning member 811 can be configured to be coupled to a production line of the optical module and receive the optical module from the production line of the optical module.

[0103] In some examples, after the optical module is produced on the optical module production line, it can be transported to the positioning member 811 through the optical module production conveyor line.

[0104] In some examples, the detection mechanism 800 may include a first detection sensor 820 . The first detection sensor 820 may be located at one side of the clamping component 810 .

[0105] In some examples, when the optical module is clamped by the clamping component 810 on the positioning member 811 , the locking tongue may be located outside the positioning groove 8111 .

[0106] In some examples, the first detection sensor 820 may be coupled to the lock tongue. When the rotating mechanism rotates and drives the lock tongue to retract into the housing, the first detection sensor 820 may detect the displacement of the lock tongue.

[0107] In some examples, the displacement value of the lock tongue detected by the first detection sensor 820 can be used to determine whether the retraction of the lock tongue can ensure unlocking between the upper computer cage.

[0108] In some examples, when the lock tongue is completely retracted into the housing, the lock tongue is unlocked from the upper computer cage.

[0109] In some examples, the first detection sensor 820 may include a through-beam sensor.

[0110] In some examples, a through-beam sensor may include a signal emitting element.

[0111] In some examples, a through-beam sensor may include a signal receiving element.

[0112] In some examples, when the lock tongue is in a locked state, the lock tongue can be located between the signal transmitter and the signal receiver. The lock tongue can block the signal emitted by the signal transmitter, so that the signal receiver cannot receive the signal emitted by the signal transmitter.

[0113] In some examples, when the rotary handle 602 rotates and drives the lock tongue to switch from the locked state to the unlocked state, the lock tongue shrinks into the housing under the drive of the rotary handle; when the lock tongue is in the unlocked state, the lock tongue moves away from between the signal transmitter and the signal receiver, so that the signal receiver can receive the signal sent by the signal transmitter. In this way, whether the lock tongue can be normally unlocked can be determined by whether the signal receiver can receive the signal sent by the signal transmitter.

[0114] In some examples, the rotary handle is rotated so that the rotary handle drives the lock tongue to switch from the locked state to the unlocked state. In some examples of the embodiments of the present application, the detection mechanism 800 may include a first drive component 830. The first drive component 830 may be located on one side of the clamping component 810.

[0115] In some examples, the first driving component 830 can be configured to drive the rotating handle to rotate relative to the housing.

[0116] In some examples, the first driving component 830 can move relative to the clamping component 810. When the optical module enters the positioning groove 8111 of the positioning member 811 and is clamped and fixed by the clamping arm, the first driving component 830 can move to the rotating handle and couple with the rotating handle.

[0117] In some examples, when the lock tongue is in the locked state, the position of the rotating handle needs to be limited to prevent the free rotation of the rotating handle from causing the lock tongue to switch to the unlocked state, resulting in the lock tongue being unable to accurately lock the optical module and the upper computer housing.

[0118] In some examples, when the locking tongue is in the locked state, the rotating handle may be resisted by the housing, so that the relative position of the rotating handle and the housing remains fixed in the locked state.

[0119] In some examples, a protrusion may be provided on the shell, and a groove may be provided on the side of the rotating handle facing the shell; the cooperation between the protrusion and the groove increases the resistance of the rotating handle to the movement of the shell, thereby keeping the relative position of the rotating handle and the shell fixed.

[0120] In some examples, a protrusion may be provided on the shell, and the protrusion may abut against a side wall of the rotating handle facing the shell, thereby increasing the resistance of the rotating handle to movement relative to the shell and keeping the relative position of the rotating handle and the shell fixed.

[0121] In some examples, after the optical module is manufactured, it is necessary to detect whether the rotary handle can maintain a fixed position with respect to the housing in a locked state, so as to prevent the rotary handle from rotating freely and causing the lock tongue to be locked.

[0122] For this purpose, refer to Figure 7 As shown, in some examples of the embodiments of the present application, the first driving component 830 has a second detection sensor 831 .

[0123] In some examples, the second detection sensor 831 may be configured to detect a torque generated by the first driving component 830 driving the rotating handle to rotate relative to the housing.

[0124] In some examples, the second detection sensor 831 may be configured to detect the force that the first driving component 830 needs to provide to the rotating handle to drive the rotating handle to rotate relative to the housing.

[0125] In some examples, when the force detected by the second detection sensor 831 is less than a preset threshold, it can be confirmed that the rotational resistance between the rotating handle and the shell is small, and it is difficult to keep the rotating handle in a fixed position on the shell.

[0126] In some examples, when the force detected by the second detection sensor 831 is greater than a preset threshold, it can be confirmed that the resistance between the rotating handle and the housing can keep the rotating handle in a fixed position.

[0127] In this way, the optical module unlocking function detection mechanism 800 provided in some embodiments of the present application can be used to detect whether the lock tongue of the optical module is retracted normally, and at the same time, the resistance between the rotating handle of the optical module and the shell can be detected; the accuracy of the optical module unlocking function detection is improved, and the yield rate of the optical module is improved.

[0128] Figure 8 This is a schematic diagram of the structure of the cooperation between the substrate, the fixing plate and the positioning member in the optical module unlocking function detection mechanism provided in some embodiments of the present application. Fig. 9 This is a schematic diagram of an enlarged exploded structure of a positioning member, a first clamping arm and a second clamping arm in an optical module unlocking function detection mechanism provided according to some embodiments of the present application.

[0129] For some examples, refer to Figure 8 and Fig. 9 As shown, in order to facilitate clamping and fixing the optical module, the clamping component 810 may include a positioning member 811 .

[0130] In some examples, the upper surface of the positioning member 811 may have a positioning groove 8111. The positioning groove 8111 may be configured to position the housing of the optical module.

[0131] In some examples, after the production and assembly of the optical module housing is completed, it can be transported to the positioning member 811 through the transmission of the production line.

[0132] In some examples, to ensure that the optical module housing transported on the production line can accurately enter the positioning groove 8111 on the positioning member 811, it is necessary to ensure that the relative position of the positioning member 811 and the production line remains unchanged.

[0133] In some examples, the detection mechanism 800 may include a substrate 840. The substrate 840 may be fixedly disposed on a production line of the optical module.

[0134] In some examples, the detection mechanism 800 may include a fixing plate 850 . The fixing plate 850 may be fixedly disposed on the substrate 840 .

[0135] In some examples, the positioning member 811 may be disposed on the fixing plate 850, so that the relative position of the positioning member 811 and the production line can be kept unchanged.

[0136] In some examples, to ensure the stability of the optical module housing in the positioning groove 8111 , the clamping component 810 may include a first clamping arm 812 . The first clamping arm 812 may be movably disposed on one side of the positioning groove 8111 .

[0137] In some examples, after the optical module enters the positioning groove 8111 , the first clamping arm 812 may move relative to the positioning groove 8111 , thereby clamping and positioning the housing of the optical module.

[0138] In some examples, the clamping component 810 may include a second clamping arm 813. The second clamping arm 813 may be movably disposed on the other side of the positioning slot 8111.

[0139] In some examples, the second clamping arm 813 may be disposed opposite to the first clamping arm 812. After the optical module enters the positioning groove 8111, the first clamping arm 812 and the second clamping arm 813 may move toward each other, thereby clamping and positioning the optical module.

[0140] In some examples, to facilitate the positioning of the optical module, refer to Fig. 9 As shown, one side of the positioning groove 8111 may have a positioning wall 8112 , and the positioning wall 8112 may abut against one end of the optical module.

[0141] In some examples, the positioning wall 8112 can abut against the electrical port end of the optical module.

[0142] In some examples, in order to facilitate the first detection sensor 820 to detect the displacement of the lock tongue from the locked state to the unlocked state, one side of the positioning member 811 has a first side wall 8113.

[0143] In some examples, the first side wall 8113 may be located on a side of the positioning member 811 facing away from the positioning wall 8112 .

[0144] In some examples, after the optical module enters the positioning groove 8111, the locking tongue may be located outside the positioning member 811. The locking tongue may be located on one side of the first side wall 8113 of the positioning member 811.

[0145] In some examples, the first detection sensor 820 may be located on one side of the first side wall 8113. In this way, the first detection sensor 820 and the lock tongue are located on the same side of the positioning member 811, so that the first detection sensor 820 can detect the movement of the lock tongue.

[0146] In some examples, to improve the accuracy of detecting the displacement of the lock tongue, the first detection sensor 820 may include a displacement sensor.

[0147] In some examples, a first sensor driver 851 may be disposed on the fixing plate 850. The displacement sensor may be disposed on the first sensor driver 851. The first sensor driver 851 may be configured to drive the displacement sensor to abut against the locking tongue with a preset force.

[0148] In some examples, after the optical module enters the positioning groove 8111 , the first clamping arm 812 and the second clamping arm 813 may move toward each other, thereby clamping and fixing the optical module.

[0149] In some examples, the first clamping arm 812 can be driven by a cylinder to move toward the second clamping arm 813. The second clamping arm 813 can be driven by a cylinder to move toward the first clamping arm 812.

[0150] In some examples, the first clamping arm 812 can be driven by a linear motor to move toward the second clamping arm 813. The second clamping arm 813 can be driven by a linear motor to move toward the second clamping arm 813.

[0151] In some examples, in the locked state, the lock tongue may be subjected to a restoring force outward of the housing. For example, as described in the foregoing embodiments of the present application, the lock tongue may be subjected to a force provided by a force providing member, so that the lock tongue remains in a state of extending out of the housing.

[0152] In some examples, the preset force applied by the first sensor to abut the lock tongue may be smaller than the force applied by the force providing member to the lock tongue.

[0153] In some examples, the detection probe of the displacement sensor can abut against the lock tongue with a preset force. The first driving component 830 rotates the rotating handle, and the lock tongue retracts into the shell under the drive of the rotating handle; the displacement sensor can continue to abut against the lock tongue with a preset force during the retraction and movement of the lock tongue. When the rotating handle is turned through a preset angle, the displacement distance of the lock tongue detected by the displacement sensor can be used to determine whether the lock tongue is completely retracted into the shell, thereby determining whether the lock tongue is switched from a locked state to an unlocked state. In this way, the accuracy of the first detection sensor in detecting the displacement of the lock tongue can be improved, thereby improving the accuracy of the proposed detection sensor in detecting the unlocking function of the optical module.

[0154] In some examples, the preset angle may be 60°.

[0155] In some examples, the preset angle may be 90°.

[0156] In some examples, the preset angle may be 75°.

[0157] In some examples, the preset angle may be 105°.

[0158] It should be noted here that the numerical values ​​and numerical ranges involved in the embodiments of the present invention are approximate values. Due to the influence of the manufacturing process, there may be a certain range of errors, which can be considered negligible by those skilled in the art.

[0159] In some examples, the first sensor driver 851 may be fixed to the fixing plate 850 .

[0160] In some examples, the first sensor driver 851 may include a cylinder.

[0161] In some examples, the first sensor driver 851 may include a linear motor.

[0162] Fig.10 This is a schematic diagram of the structure of a positioning member in an optical module unlocking function detection mechanism provided according to some embodiments of the present application.

[0163] For some examples, refer to Fig. 9 and Fig.10 As shown, the positioning member 811 may be provided with a first protrusion 8114 .

[0164] In some examples, the positioning member 811 may be provided with a second protrusion 8115. The second protrusion 8115 may be arranged opposite to the first protrusion 8114.

[0165] In some examples, a positioning groove 8111 is formed between the first protrusion 8114 and the second protrusion 8115 .

[0166] In some examples, in order to facilitate the first clamping arm 812 and the second clamping arm 813 to clamp and fix the optical module housing, a first through groove 81141 may be provided on the first protrusion 8114. The first through groove 81141 may be connected to the positioning groove 8111.

[0167] In some examples, the first clamping arm 812 may be inserted into the first through groove 81141. The first clamping arm 812 may move in the first through groove 81141. A portion of the first clamping arm 812 may extend into the positioning groove 8111 and clamp and fix the optical module housing.

[0168] In some examples, the second protrusion 8115 may be provided with a second passing groove 81151. The second passing groove 81151 may be communicated with the positioning groove 8111.

[0169] In some examples, the second clamping arm 813 may be inserted into the second through groove 81151. The second clamping arm 813 may move in the second through groove 81151. A portion of the second clamping arm 813 may extend into the positioning groove 8111 and clamp and fix the optical module housing.

[0170] In some examples, to facilitate the optical module to enter the positioning groove 8111, a first guiding slope 81142 may be provided on one side of the first protrusion 8114 facing the second protrusion 8115. The first guiding slope 81142 may be located at the notch of the positioning groove 8111. The first guiding slope 81142 may be inclined relative to the inner wall of the positioning groove 8111.

[0171] In some examples, a second guide slope 81152 may be provided on a side of the second protrusion 8115 facing the first protrusion 8114. The second guide slope 81152 may be located at the notch of the positioning groove 8111. The second guide slope 81152 may be disposed opposite to the first guide slope 81142. The second guide slope 81152 may be disposed obliquely relative to the inner wall of the positioning groove 8111.

[0172] In some examples, a first distance may be provided between the top end of the first guide slope 81142 and the top end of the second guide slope 81152. A second distance may be provided between the bottom end of the first guide slope 81142 and the bottom end of the second guide slope 81152.

[0173] In some examples, the first distance may be greater than the second distance.

[0174] In some examples, the distance between the first guiding bevel 81142 and the second guiding bevel 81152 decreases from the notch of the positioning groove 8111 to the bottom wall of the positioning groove 8111. In this way, the notch size of the positioning groove 8111 is larger, which facilitates the optical module to fall into the notch of the positioning groove 8111. After the optical module falls into the notch of the positioning groove 8111, it falls into the positioning groove 8111 under the guidance of the first guiding bevel 81142 and the second guiding bevel 81152, which facilitates the optical module to accurately enter the positioning groove 8111, thereby improving the automation of the detection of the unlocking function of the optical module.

[0175] Fig.11 This is a structural schematic diagram of a first clamping arm and a second clamping arm in an optical module unlocking function detection mechanism provided according to some embodiments of the present application. Fig.12 Another structural schematic diagram of the first clamping arm and the second clamping arm in the optical module unlocking function detection mechanism provided according to some embodiments of the present application.

[0176] In some examples, since the displacement sensor is continuously in contact with the lock tongue with a preset force, in order to prevent the force of the displacement sensor lock tongue from causing the optical module to move in the positioning groove 8111, refer to Fig.11 and Fig.12 As shown, the first clamping arm 812 may have a first inclined wall 8121 on one side facing the second clamping arm 813 .

[0177] In some examples, the first inclined wall 8121 may be inclined relative to an inner wall of the positioning groove 8111 .

[0178] In some examples, along a direction from the opening of the positioning groove 8111 to a bottom wall of the positioning groove 8111 , the first inclined wall 8121 is inclined away from the second clamping arm 813 .

[0179] In some examples, a side of the second clamping arm 813 facing the first clamping arm 812 may have a second inclined wall 8131 .

[0180] In some examples, along a direction from the opening of the positioning groove 8111 to a bottom wall of the positioning groove 8111 , the second inclined wall 8131 is inclined away from the first clamping arm 812 .

[0181] In some examples, there is a third distance between the top of the first inclined wall 8121 and the top of the second inclined wall 8131 .

[0182] In some examples, there is a fourth distance between the bottom of the first inclined wall 8121 and the bottom of the second inclined wall 8131 .

[0183] In some examples, the third distance is less than the fourth distance.

[0184] In some examples, the top height of the first clamping arm 812 may be higher than the upper surface of the optical module.

[0185] In some examples, the top height of the second clamping arm 813 may be higher than the upper surface of the optical module.

[0186] In some examples, when the first clamping arm 812 and the second clamping arm 813 are clamped on the optical module, the third distance can be smaller than the width of the optical module. In this way, when the first clamping arm 812 and the second clamping arm 813 clamp the optical module, the clamping force of the first inclined wall 8121 and the second inclined wall 8131 on the optical module housing can have a component force toward the bottom wall of the positioning groove 8111. In other words, the first inclined wall 8121 and the second inclined wall 8131 can press the housing onto the bottom wall of the positioning groove 8111. In this way, the force of the displacement sensor on the lock tongue can be prevented from causing the optical module to move or come out of the positioning groove 8111, thereby improving the accuracy of the displacement sensor in detecting the displacement of the lock tongue.

[0187] Fig.13 This is a structural schematic diagram of the cooperation between the first driving component and the substrate in the optical module unlocking function detection mechanism provided according to some embodiments of the present application.

[0188] For some examples, refer to Fig.13 As shown, the first driving component 830 may include a rotation driving member 832. The rotation driving member 832 may be disposed on a base plate 840.

[0189] In some examples, the rotary drive 832 may include a rotary motor.

[0190] In some examples, the second detection sensor 831 may include a torque detection sensor. The torque detection sensor may be connected to the output shaft of the rotation driving member 832.

[0191] In some examples, when the output shaft of the rotary drive member 832 rotates, the torque sensor can detect the torque of the output shaft of the rotary drive member 832 .

[0192] In some examples, the first driving component 830 may include a claw 833. The claw 833 may be disposed on the output shaft of the rotating driving member 832.

[0193] In some examples, the output shaft of the rotary drive member 832 can drive the claw 833 to rotate. The claw 833 can be configured to be coupled to the rotary handle 602. The claw rotates under the drive of the rotary drive member 832, thereby driving the rotary handle 602 to rotate relative to the housing.

[0194] In some examples, the torque sensor can be configured to detect the torque when the output shaft of the rotary drive member 832 rotates, thereby determining whether the resistance between the rotary handle and the housing is normal.

[0195] In some examples, when the torque value is greater than or equal to a preset threshold, it is determined that the resistance between the rotating handle and the housing is normal and the fit between the rotating handle and the housing meets the requirements.

[0196] Fig.14 This is a schematic diagram of the structure of a clamping claw in an optical module unlocking function detection mechanism provided according to some embodiments of the present application.

[0197] In some examples, the claw 833 may include a first claw arm 8331. When the claw 833 is coupled to the rotating handle, the first claw arm 8331 may be located on one side of the rotating handle along the rotating direction.

[0198] In some examples, the first claw arm 8331 may be located at the rear side of the rotating handle along the rotation direction (taking the rotation direction when unlocking as an example). The first claw arm 8331 may push the rotating handle to rotate, so as to drive the lock tongue to switch from the locked state to the unlocked state.

[0199] In some examples, after the unlocking function of the optical module is tested, the position of the rotary handle needs to be reset so that the optical module can enter the next production process.

[0200] In some examples, the claw 833 may include a second claw arm 8332. The second claw arm 8332 may be disposed opposite to the first claw arm 8331.

[0201] In some examples, the second claw arm 8332 may be located on the other side of the rotating handle along the rotation direction (taking the rotation direction when unlocking as an example). The second claw arm 8332 may be located on the front side of the rotating handle along the rotation direction.

[0202] In some examples, after the unlocking function of the optical module is detected, the first driving component 830 can reversely drive the claw 833, and the first claw arm 8331 pushes the rotating handle to rotate in the reverse direction, thereby resetting the rotating handle.

[0203] In some examples, a protrusion may be provided on the upper surface of the optical module.

[0204] In some examples, the rotating handle may have a recessed portion, which may cooperate with the protruding portion so that the housing provides resistance to the rotating handle in the rotating direction.

[0205] In some examples, in order to avoid interference between the first claw arm 8331 and the second claw arm 8332 and the protrusion, the first claw arm 8331 may be provided with a first avoidance notch 83311 , and the second claw arm 8332 may be provided with a second avoidance notch 83321 .

[0206] In some examples, the first avoidance notch 83311 and the second avoidance notch 83321 may be configured as avoidance protrusions, so that the first claw arm 8331 and the second claw arm 8332 can rotate the rotary handle.

[0207] In some examples, when the rotary drive member 832 reversely rotates the driving claw 833 and the claw 833 reversely rotates the rotary handle to reset the rotary handle, it is necessary to detect whether the rotary handle is reset to the correct position.

[0208] Fig.15 This is another structural schematic diagram of the cooperation between the first driving component and the substrate in the optical module unlocking function detection mechanism provided according to some embodiments of the present application. Fig.16 for Fig.15 Schematic diagram of the local enlarged structure at point A in the middle.

[0209] For some examples, refer to Fig.15 and Fig.16 As shown, the detection mechanism 800 may include a reset detection sensor 870 .

[0210] In some examples, a reset trigger 871 may be provided on the output shaft of the rotary drive member 832. When the rotary drive member 832 drives the claw 833 to reset, and the rotary handle is reset to the locked state, the reset trigger 871 may be detected by the reset detection sensor 870 and trigger a detection signal, thereby determining that the rotary drive member 832 is reset to the correct position, i.e., the rotary handle is reset to the correct position.

[0211] In some examples, the reset detection sensor 870 may include a through-beam sensor.

[0212] In some examples, the reset trigger 871 may include a signal blocking member. When the rotary handle 602 is reset to its original position, the reset trigger 871 may be located between the signal transmitting member and the signal receiving member of the through-beam sensor.

[0213] In some examples, after the unlocking function of the optical module is detected, in order to facilitate the optical module to enter the next production process, the claw 833 needs to be removed from the rotating handle, that is, the position of the first driving component 830 needs to be moved.

[0214] In some examples, after the next optical module enters the positioning groove 8111, the claw 833 needs to be moved to a position where it is coupled to the rotating handle.

[0215] Fig.17 This is a schematic diagram of an enlarged structure of the cooperation between the first driving component and the second driving component in the optical module unlocking function detection mechanism provided according to some embodiments of the present application.

[0216] For some examples, refer to Fig.15 and Fig.17 As shown, the detection mechanism 800 may include a second driving component 860. The second driving component 860 may be disposed on the substrate 840.

[0217] In some examples, the second driving component 860 can be connected to the first driving component 830. The second driving component 860 can be configured to drive the first driving component 830 to move relative to the clamping component 810 so that the output shaft of the rotating driving member is coaxial with the rotating shaft of the rotating handle. In this way, it can be ensured that the rotating shaft of the rotating handle is coaxial with the rotating shaft of the card turn, and it can be ensured that the card turn only provides a force on the rotating handle in the rotation direction, which can improve the accuracy of the detection of the rotating handle.

[0218] In some examples, the second driving component 860 may include a first driving member 861. The first driving member 861 may be disposed on a base.

[0219] In some examples, the first driving member 861 can include a linear motor.

[0220] In some examples, the first driving member 861 may include a cylinder.

[0221] In some examples, the first driving member 861 may include a piston cylinder.

[0222] In some examples, the first driving component 830 may be connected to the first driving member 861. The first driving member 861 may drive the first driving component 830 to move on the base, thereby adjusting the relative position of the claw 833 and the rotating handle.

[0223] In some examples, the second driving component 860 may include a first connecting member 862. The first connecting member 862 may be connected to the first driving member 861.
