[0062] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0063] The embodiments of the present application provide an optical transceiver assembly fixing structure, an optical transceiver module and a camera module, which can solve the technical problem in the related art that two interfaces occupy a large volume in the vehicle.

[0064] See also Figures 1 to 3As shown, an optical transceiver assembly fixing structure 100 provided in an embodiment of the present application includes: an adapter body 1, wherein the adapter body 1 has an installation cavity 11 and a docking socket 10, and the docking socket 10 is connected to the installation cavity 11; an optical transceiver assembly 2, wherein the optical transceiver assembly 2 is installed in the installation cavity 11; a fixing member 3, wherein the fixing member 3 is fixed to the adapter body 1, wherein the fixing member 3 and the adapter body 1 are integrally formed or separately formed, and the fixing member 3 and the adapter body 1 wrap the optical transceiver assembly 2 therein; and the adapter body 1 also accommodates a conductive sheet 6, wherein the conductive sheet 6 is exposed at the docking socket 10.

[0065] In this embodiment, the front of the adapter body 1 is provided with a docking socket 10, and the docking socket 10 is used for docking connectors, such as optoelectronic connectors, etc. The rear of the adapter body 1 is provided with a mounting cavity 11 for mounting the optical transceiver assembly 2, and the optical transceiver assembly 2 can be, for example, a bosa. The fixing member 3 is located at the rear of the adapter body 1, and wraps the optical transceiver assembly 2 from the rear, so that the optical transceiver assembly 2 is completely accommodated in the adapter body 1 and the fixing member 3, and the pin 21 of the optical transceiver assembly 2 needs to cooperate with other devices to realize signal transmission, so its pin 21 needs to extend out of the fixing member 3 and the adapter body 1. The adapter body 1 in this embodiment can be integrally formed with the fixing member 3, or they can be separately formed and then fixed together, for example, they can be welded together, or they can be integrally injection molded.

[0066] In this embodiment, a mounting cavity 11 adapted to the optical transceiver assembly 2 is provided in the adapter body 1, and a limiting surface for limiting the front and rear, left and right, and up and down of the optical transceiver assembly 2 can be provided in or around the mounting cavity 11, so that the optical transceiver assembly 2 can be accurately positioned after being installed in the axially distributed adapter body 1 and the fixing member 3, and will not move at will. When the optical transceiver assembly 2 is installed on the main board 200 (such as PCB), the optical transceiver assembly 2 will not be exposed on the surface of the main board 200, but will be wrapped inside the adapter body 1 and the fixing member 3, which can fully protect the optical transceiver assembly 2, and the pins 21 of the optical transceiver assembly 2 can be exposed to the outside, which is convenient for welding with the main board 200. At the same time, the conductive sheet 6 in the adapter body 1 is exposed in the docking socket 10, which can not only realize the transmission of optical signals, but also realize the power supply of BOSA or other components, solving the technical problem of the two interfaces occupying a large volume in the vehicle in the related technology.

[0067] At the same time, this embodiment divides the structure of fixing the optical transceiver assembly 2 into an adapter body 1 and a fixing member 3 arranged along the axial direction (i.e., the front-to-back direction), which can not only fully wrap the optical transceiver assembly 2 in the adapter body 1 and the fixing member 3, but also, the arrangement along the front-to-back direction makes the part of the adapter body 1 located in front of the optical transceiver assembly 2 an integral whole, which is convenient for sealing at the front of the adapter body 1, and is suitable for the vehicle field. In other embodiments, the adapter body 1 and the fixing member 3 can also be arranged to be distributed in other directions, such as in the up-down direction, so that the optical transceiver assembly 2 can be wrapped from the up-down direction.

[0068] Further, in one embodiment, see Figure 5 and Fig. 9 As shown, the adapter body 1 has a slide groove 12 extending axially, the optical transceiver assembly 2 is inserted into the mounting cavity 11 along the slide groove 12 , and the optical transceiver assembly 2 is at least partially accommodated in the slide groove 12 . In this embodiment, the adapter body 1 is preferably integrally injection molded, the front portion of the adapter body 1 is cylindrical, the rear portion is integrally connected to the front portion and extends backward, the slide groove 12 is provided at the rear portion of the adapter body 1 and penetrates the adapter body 1 backward, so that when installing, the optical transceiver assembly 2 can be pushed forward into the installation cavity 11 from the rear of the adapter body 1 along the slide groove 12, and in the process of the optical transceiver assembly 2 moving forward along the slide groove 12, the slide groove 12 can limit and guide the optical transceiver assembly 2, so that the optical transceiver assembly 2 moves axially until it slides into the installation cavity 11 in the front, and when the optical transceiver assembly 2 slides to the final position, the front portion of the optical transceiver assembly 2 is accommodated in the installation cavity 11, and the rear portion is accommodated in the slide groove 12; at the same time, when the fixing member 3 is buckled to the adapter body 1, the upper portion of the optical transceiver assembly 2 is accommodated in the fixing member 3.

[0069] Further, in some optional embodiments, see Figure 3 and Figure 8As shown, the fixing member 3 and / or the adapter body 1 are further provided with a mainboard clamping portion 5 and a mainboard positioning column 4. In this embodiment, the mainboard positioning column 4 and the mainboard clamping portion 5 that cooperate with the mainboard 200 can be provided on the fixing member 3; the mainboard positioning column 4 and the mainboard clamping portion 5 that cooperate with the mainboard 200 can also be provided on the adapter body 1 alone; the mainboard positioning column 4 and the mainboard clamping portion 5 can also be provided on both the fixing member 3 and the adapter body 1; or the mainboard positioning column 4 can be provided on one of the fixing member 3 and the adapter body 1, and the mainboard clamping portion 5 can be provided on the other. In this embodiment, by setting a mainboard positioning column 4 and a mainboard clamping portion 5 on the fixing member 3 and / or the adapter body 1, when the optical transceiver component fixing structure 100 is installed on the mainboard 200, the mainboard positioning column 4 can position and limit the position where the optical transceiver component fixing structure 100 is installed on the mainboard 200, and the mainboard clamping portion 5 can be clamped with the mainboard 200, so that the optical transceiver component fixing structure 100 is stably fixed to the mainboard 200. In addition to the connection between the pins 21 of the optical transceiver component 2 and the mainboard 200, the mainboard clamping portion 5 is added to fix the mainboard 200, so that the optical transceiver component 2 is not easily separated from the mainboard 200, thereby improving the stability and fixing strength. At the same time, the provision of the mainboard positioning column 4 can improve the accuracy of the installation of the optical transceiver component 2 on the mainboard 200.

[0070] Preferably, corresponding positioning holes 202 and snap-in holes 203 are provided on the mainboard 200 . The positioning holes 202 cooperate with the mainboard positioning columns 4 for positioning, and the snap-in holes 203 cooperate with the mainboard snap-in parts 5 for snap-in fixing.

[0071] In the related art, since home optical modems and ONUs are in a static environment, usually the internal devices such as BOSA do not need special protection and can be directly soldered to the PCB. However, if the same method is used in a car, the severe vibration of the car during operation may cause the BOSA device to be desoldered from the PCB. The adapter body 1 and the fixing part 3 provided in this embodiment are designed to wrap the BOSA, and the BOSA is fixed to the PCB and the device casing through the fixing part 3 and / or the adapter body 1, thereby improving the vibration resistance of the equipment.

[0072] In one embodiment, the axes of the mainboard clamping portion 5 and the mainboard positioning column 4 are both perpendicular to the axis of the adapter body 1 , or the axes of the mainboard clamping portion 5 and the mainboard positioning column 4 are both parallel to the axis of the adapter body 1 .

[0073] For details, see Figure 3 and Figure 8As shown, in one embodiment, the fixing member 3 has a first assembly surface 31 and a second assembly surface 32, the first assembly surface 31 is perpendicular to the axis of the adapter body 1, the second assembly surface 32 is perpendicular to the first assembly surface 31, and the first assembly surface 31 and the second assembly surface 32 are both provided with the mainboard positioning column 4 and the mainboard clamping portion 5; the adapter body 1 has a third assembly surface 13, the third assembly surface 13 is flush with the second assembly surface 32, and the third assembly surface 13 is also provided with the mainboard positioning column 4 and the mainboard clamping portion 5.

[0074] In this embodiment, the optical transceiver assembly 2 has pins 21 extending along the axial direction of the adapter body 1, and also has pins 21 extending in the vertical direction. The pins 21 extending along the axial direction are in a horizontal state and are perpendicular to the vertical pins 21. The mainboard positioning column 4 and the mainboard clamping portion 5 are arranged on the vertical first assembly surface 31, so that the optical transceiver assembly fixing structure 100 and the mainboard 200 can be installed vertically (see Fig.10 and the motherboard positioning column 4 and the motherboard clamping portion 5 are arranged on the horizontal second assembly surface 32 and the third assembly surface 13, so that the optical transceiver assembly fixing structure 100 and the motherboard 200 can be installed horizontally (see Fig.11 When installed in a vertical position, the pins 21 extending horizontally on the optical transceiver assembly 2 are inserted into the mainboard 200 and welded to the mainboard 200 to achieve a hard connection, and the pins 21 extending vertically can be softly connected to the mainboard 200 through a pin soft tape; when installed in a horizontal position, the pins 21 extending vertically on the optical transceiver assembly 2 are inserted into the mainboard 200 and welded to the mainboard 200 to achieve a hard connection, and the pins 21 extending horizontally can be softly connected to the mainboard 200 through a pin soft tape.

In this embodiment, there is a conductive sheet 6 on the left side of the optical transceiver assembly 2 and a conductive sheet 6 on the right side, and the two symmetrical conductive sheets 6 are exposed in the docking socket 10 for achieving electrical connection.

[0076] Further, in one embodiment, see Figure 7 As shown, the conductive sheet 6 has a first pin 61 and / or a second pin 62 (see Figure 4As shown), the first pin 61 is perpendicular to the axis of the adapter body 1, and the second pin 62 is parallel to the axis of the adapter body 1. In this embodiment, the adapter body 1 is also provided with two terminal slots 19, each of which is provided with a conductive sheet 6, and the terminal slot 19 can wrap the conductive sheet 6 inside. The two terminal slots 19 extend along the axial direction of the adapter body 1, and the two terminal slots 19 are arranged at intervals along the left-right direction and are distributed on the left and right sides of the optical transceiver assembly 2. At the same time, the terminal slot 19 is separated from the slide slot 12 in the left-right direction, and the optical transceiver assembly 2 is separated from the conductive sheet 6 after being installed in the slide slot 12 and the installation cavity 11. By installing both the optical transceiver assembly 2 and the conductive sheet 6 in the adapter body 1, the adapter body 1 can realize both the transmission of optical signals and power supply; at the same time, each conductive sheet 6 can be provided with a first pin 61 alone, a second pin 62 alone, or a first pin 61 and a second pin 62 at the same time. The first pin 61 and the second pin 62 are both used for welding and fixing to the mainboard 200. The second pin 62 extends into the fixing member 3, which can enhance the connection strength between the adapter body 1 and the fixing member 3. At the same time, the conductive sheet 6 can adapt to the mainboard 200 installed vertically and horizontally.

[0077] Further, in one embodiment, see Figure 6 and Figure 7 As shown, the adapter body 1 is provided with a first snap-fit ​​position 14 and a second snap-fit ​​position 15, and the fixing member 3 is snap-fitted to the first snap-fit ​​position 14 and the second snap-fit ​​position 15. The first snap-fit ​​position 14 limits the fixing member 3 from moving relative to the adapter body 1 along the axial direction and the first direction of the adapter body 1, and the first direction is perpendicular to the axial direction of the adapter body 1; the second snap-fit ​​position 15 limits the fixing member 3 from moving along the second direction, and the second direction is perpendicular to the first direction, and the second direction is perpendicular to the axial direction of the adapter body 1.

A first guiding inclined surface 1421 is also provided on one side of the second protrusion 142 close to the fixing member 3; the front end of the fixing member 3 extends forward to form two connecting portions 35, and the inner side of each connecting portion 35 is provided with a first buckling The first holding portion 33 is provided with a second guiding bevel 331 cooperating with the first guiding bevel 1421 at the front end thereof. When the fixing member 3 is inserted into the adapter body 1, the second guiding bevel 331 cooperates with the first guiding bevel 1421. When the first locking portion 33 passes over the T-shaped second protrusion 142 and enters the first locking position 14, the fixing member 3 is clamped with the adapter body 1, and the second protrusion 142 prevents the first locking portion 33 from being separated from the first locking position 14.

[0085] See also Fig.12 As shown, the embodiment of the present application further provides a camera module, which may include: a camera cover 300, in which the above-mentioned optical transceiver module is installed. The optical transceiver module in this embodiment may adopt the optical transceiver module provided in any of the above-mentioned embodiments, and realize the corresponding functions, which will not be repeated here.

[0086] Further, in one embodiment, see Fig.12 As shown, the camera cover body 300 includes a first camera cover body 301, and the first camera cover body 301 has a receiving cavity 3011 and a plug-in hole 3012. The receiving cavity 3011 and the plug-in hole 3012 are distributed in the first camera cover body 301 along the axial direction of the plug-in hole 3012, and are interconnected; the optical transceiver module is at least partially received in the receiving cavity 3011, and the adapter body 1 of the optical transceiver module is inserted into the plug-in hole 3012. In this embodiment, the plug hole 3012 is located in front of the receiving cavity 3011, and the plug hole 3012 penetrates the first cover body 301 of the camera forward, and the receiving cavity 3011 penetrates the first cover body 301 of the camera backward, so that the plug hole 3012 and the receiving cavity 3011 penetrate the first cover body 301 of the camera front and back, and the optical transceiver module is installed in the first cover body 301 of the camera from back to front, and the front part of the adapter body 1 passes through the receiving cavity 3011 and is inserted into the plug hole 3012, which is convenient for the front part of the adapter body 1 to connect with other connectors. At the same time, the plug hole 3012 can position the optical transceiver module in the first cover body 301 of the camera.

[0087] Based on the above technical solution, see Fig.12 As shown, preferably, the adapter body 1 is provided with a limiting plane 1411, and the limiting plane 1411 is perpendicular to the axis of the adapter body 1; the first camera cover 301 forms a limiting step 3013 at the connection between the receiving cavity 3011 and the plug hole 3012 (see Fig.13As shown in the figure, the limiting step 3013 cooperates with the limiting plane 1411 to limit. In this embodiment, the first protrusion 141 located at the top of the adapter body 1 is provided with the limiting plane 1411, and the limiting plane 1411 is located at the front end surface of the first protrusion 141. At the same time, the limiting plane 1411 can also be provided at the bottom of the adapter body 1. The limiting plane 1411 is a vertical plane. The limiting plane 1411 at the top and the limiting plane 1411 at the bottom can be coplanar or non-coplanar. Since the internal size of the receiving cavity 3011 is larger than the internal size of the plug hole 3012, a step will be formed at the connection between the receiving cavity 3011 and the plug hole 3012, that is, the limiting step 3013. When the optical transceiver module is inserted into the first cover body 301 of the camera, the limiting step 3013 will fit the limiting plane 1411 in the front-to-back direction, and prevent the optical transceiver module from moving forward further, thereby limiting the optical transceiver module. In some optional embodiments, the adapter body 1 may also be integrally formed with the first camera cover 301 .

[0088] Further, see Fig.14 As shown, on the basis of the above technical solution, preferably, the adapter body 1 is further provided with a buckle 18, and the buckle 18 abuts against one end of the first camera cover 301 along the axial direction of the adapter body 1, so that the buckle 18 and the limiting plane 1411 limit the axial movement of the adapter body 1 relative to the first camera cover 301 along the plug hole 3012. In this embodiment, the adapter body 1 is provided with two buckles 18, and the two buckles 18 are symmetrically distributed. When the adapter body 1 is inserted into the first camera cover 301, the buckle 18 will pass through the plug hole 3012 from the front end of the first camera cover 301 and can abut against the front end surface of the first camera cover 301, so that the buckle 18 and the limiting plane 1411 clamp the first camera cover 301 one after the other, and the first camera cover 301 and the optical transceiver module are fixed to each other.

[0089] Further, in some embodiments, see Fig.13 As shown, the adapter body 1 is further provided with a key slot 17, and the key slot 17 extends along the axial direction of the adapter body 1; a limit key 3014 is provided in the plug hole 3012, and the limit key 3014 is plugged into the key slot 17. In this embodiment, by providing the key slot 17 on the adapter body 1 and providing the limit key 3014 in the first camera cover 301, and the limit key 3014 is plugged into the key slot 17, the optical transceiver module can be positioned in the radial direction, and the optical transceiver module is prevented from rotating in the first camera cover 301.

[0090] Further, see Fig.15As shown, in one embodiment, a fixing column 3015 is provided in the accommodating cavity 3011, and an elastic pad 303 is fixed to the end of the fixing column 3015; a through hole 201 is opened on the main board 200 of the optical transceiver module, and a fastener 400 is passed through the through hole 201, and the fastener 400 passes through the elastic pad 303 and is fixed to the fixing column 3015, and the elastic pad 303 is clamped between the main board 200 and the fixing column 3015, and the inner diameter of the through hole 201 is larger than the outer diameter of the fastener 400 located in the through hole 201. In this embodiment, the elastic pad 303 here is a gasket with a certain thickness and capable of elastic deformation, for example, it can be a silicone gasket or a rubber gasket, etc. An inner hole is opened in the elastic pad 303, and a threaded hole can be provided in the fixing column 3015. The fastener 400 can be a screw, for example. The fastener 400 passes through the mainboard 200 and the elastic pad 303, and is threadedly connected to the fixing column 3015, thereby further fixing the rear of the optical transceiver module to the first cover body 301 of the camera. Because the optical transceiver module has been positioned and fixed to the first cover body 301 of the camera through the adapter body 1 before the fastener 400 is used to fix the main board 200, there will be a problem of over-positioning if the main board 200 is fixed at this time. Therefore, this embodiment provides a through hole 201 with a slightly larger inner diameter on the main board 200 to cooperate with the fastener 400 to reserve an assembly gap, which can solve the problem that the main board 200 does not align left and right with the first cover body 301 of the camera. At the same time, a soft silicone gasket is provided at the end of the fixing column 3015 to fill the assembly gap and solve the problem that the main board 200 does not align front and back with the first cover body 301 of the camera.

[0091] Furthermore, in one embodiment, since the overall sealing of the interior of the camera cover 300 needs to meet IP68 and IP69K, an adapter sealing ring 7 is sandwiched between the adapter body 1 and the inner wall of the plug-in hole 3012; the camera cover 300 also includes a second camera cover 302, and the second camera cover 302 is fixed to the first camera cover 301, and a sealing strip is sandwiched at the joint between the first camera cover 301 and the second camera cover 302, so that the optical transceiver module is sealed in the second camera cover 302 and the first camera cover 301. In this embodiment, the second cover body 302 of the camera is the front cover of the camera, and the first cover body 301 of the camera is the back cover of the camera. A sealing groove 3016 is provided around the edge of the first cover body 301 of the camera, and a sealing strip is installed in the sealing groove 3016. After the second cover body 302 of the camera is fixed together with the first cover body 301 of the camera, the optical transceiver module is sealed in the first cover body 301 of the camera and the second cover body 302 of the camera through the adapter sealing ring 7 and the sealing strip.

[0092] Further, see Fig.21As shown, a soft tape 204 is connected to the main board 200, and the main board 200 in the camera back cover and the PCB of the camera front cover are floatingly connected via the soft tape 204 / PIN.

[0093] See also Figure 16 to Figure 17 as well as Fig.21 As shown, it is a vertical camera module. At this time, the optical transceiver module in the camera cover 300 is installed in a vertical manner; see Figures 18 to 20 as well as Fig. 22 As shown, it is a horizontal camera module. At this time, the optical transceiver module in the camera cover 300 is installed horizontally.
