[0062] In order to enable persons skilled in the art to better understand the scheme of the present application, the technical scheme 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, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by persons skilled in the art without creative labor fall within the scope of protection of the present application.

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

[0064] Reference is made to Figures 1 to 3As shown, the optical transceiver assembly fixing structure 100 provided by the embodiment of the application comprises an adapter main body 1, the adapter main body 1 is internally provided with a mounting cavity 11 and a mating socket 10, the mating socket 10 is in communication with the mounting cavity 11; an optical transceiver assembly 2 is mounted in the mounting cavity 11; a fixing member 3 is fixedly arranged on the adapter main body 1, the fixing member 3 is integrally formed with the adapter main body 1 or separately formed and fixed with the adapter main body 1, and the fixing member 3 and the adapter main body 1 wrap the optical transceiver assembly 2; a conductive sheet 6 is further arranged in the adapter main body 1, and the conductive sheet 6 is exposed to the mating socket 10.

[0065] In the embodiment, the front part of the adapter main body 1 is provided with the mating socket 10, which is used for connecting a connector such as an optical and electrical connector. The rear part of the adapter main body 1 is provided with the mounting cavity 11 for mounting the optical transceiver assembly 2, which can be a bosa for example. The fixing member 3 is located at the rear of the adapter main 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 main body 1 and the fixing member 3. The pin 21 of the optical transceiver assembly 2 needs to be extended out of the fixing member 3 and the adapter main body 1 to cooperate with other devices to realize signal transmission. The adapter main body 1 in the embodiment can be integrally formed with the fixing member 3, or separately formed and fixed together, for example, can be welded together or integrally injection molded.

[0066] In the embodiment, the mounting cavity 11 adapted to the optical transceiver assembly 2 is arranged in the adapter main body 1, and a limiting surface for limiting the front, rear, left, right and up and down of the optical transceiver assembly 2 can be arranged in the mounting cavity 11 or around the mounting cavity 11, so that the optical transceiver assembly 2 can be accurately positioned after being mounted into the adapter main body 1 and the fixing member 3 distributed in the axial direction and cannot be moved at will. When the optical transceiver assembly 2 is mounted to the main board 200 (such as a PCB), the optical transceiver assembly 2 is not exposed on the surface of the main board 200, but is wrapped inside the adapter main body 1 and the fixing member 3, so that the optical transceiver assembly 2 can be fully protected, and the pin 21 of the optical transceiver assembly 2 can be exposed outside to facilitate welding with the main board 200. At the same time, the conductive sheet 6 in the adapter main body 1 is exposed to the mating socket 10, which can not only realize optical signal transmission, but also realize power supply for the BOSA or other components, thereby solving the technical problem of occupying a large volume in the vehicle by two interfaces in the related art.

[0067] Meanwhile, the structure of fixing the optical transceiver assembly 2 is divided into the adapter body 1 and the fixing member 3 arranged along the axial direction (i.e. the front-rear direction) in the embodiment, the optical transceiver assembly 2 can be fully wrapped in the adapter body 1 and the fixing member 3, and the arrangement along the front-rear 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 the front part of the adapter body 1 and suitable for the vehicle-mounted field. In other embodiments, the adapter body 1 and the fixing member 3 can be arranged along other directions, for example, the up-down direction, and the optical transceiver assembly 2 can be wrapped from the up-down direction.

[0068] Further, in an embodiment, as shown in Figure 5 and Figure 9 , the adapter body 1 extends along the axial direction with a sliding groove 12, the optical transceiver assembly 2 is inserted into the mounting cavity 11 along the sliding groove 12, and the optical transceiver assembly 2 is at least partially accommodated in the sliding groove 12. In the embodiment, the adapter body 1 is preferably integrally injection molded, the front part of the adapter body 1 is cylindrical, the rear part is integrally connected with the front part and extends backward to form the sliding groove 12 arranged in the rear part of the adapter body 1 and penetrating the adapter body 1 backward, so that the optical transceiver assembly 2 can be pushed into the mounting cavity 11 from the rear of the adapter body 1 along the sliding groove 12 during installation. During the movement of the optical transceiver assembly 2 along the sliding groove 12, the sliding groove 12 can limit and guide the optical transceiver assembly 2 to move along the axial direction until the optical transceiver assembly 2 slides into the mounting cavity 11 in front, and when the optical transceiver assembly 2 slides to the final position, the front part of the optical transceiver assembly 2 is accommodated in the mounting cavity 11 and the rear part is accommodated in the sliding groove 12. Meanwhile, when the fixing member 3 is buckled to the adapter body 1, the upper part of the optical transceiver assembly 2 is accommodated in the fixing member 3.

[0069] Further, in some optional embodiments, as shown in Figure 3 and Figure 8As shown, the fixing member 3 and / or the adapter body 1 is 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, or can be separately provided on the adapter body 1, or can be provided on both the fixing member 3 and the adapter body 1, or can be provided on one of the fixing member 3 and the adapter body 1 and the other one of the fixing member 3 and the adapter body 1. In this embodiment, by providing the mainboard positioning column 4 and the mainboard clamping portion 5 on the fixing member 3 and / or the adapter body 1, when the optical transceiver assembly fixing structure 100 is installed on the mainboard 200, the mainboard positioning column 4 can position and limit the position of the optical transceiver assembly fixing structure 100 on the mainboard 200, and the mainboard clamping portion 5 can be clamped with the mainboard 200, so that the optical transceiver assembly fixing structure 100 is stably fixed to the mainboard 200. In addition to the pin 21 of the optical transceiver assembly 2 being connected with the mainboard 200, the mainboard clamping portion 5 is further fixed with the mainboard 200, so that the optical transceiver assembly 2 is not easy to be separated from the mainboard 200, and the stability and the fixing strength are improved. At the same time, by providing the mainboard positioning column 4, the installation precision of the optical transceiver assembly 2 on the mainboard 200 is improved.

[0070] Preferably, corresponding positioning holes 202 and clamping holes 203 are formed on the mainboard 200, the positioning holes 202 cooperate with the mainboard positioning column 4 to position, and the clamping holes 203 cooperate with the mainboard clamping portion 5 to clamp and fix.

[0071] In the related art, since the home optical network terminal and the ONU are in a static environment, the internal BOSA and other devices do not need special protection and can be directly welded to the PCB. However, if the same method is used on a vehicle, the severe vibration during the running of the vehicle can cause the BOSA device to be detached from the PCB, etc. The adapter body 1 and the fixing member 3 provided in this embodiment wrap the BOSA, and the fixing member 3 and / or the adapter body 1 fix the BOSA to the PCB and the device shell, thereby improving the anti-vibration performance of the device.

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

In vertical installation, the horizontally extending pins 21 of the optical transceiver assembly 2 are inserted into the mainboard 200 and welded with the mainboard 200 to achieve hard connection, and the vertically extending pins 21 can be connected with the mainboard 200 through pin soft belt to achieve soft connection; in horizontal installation, the vertically extending pins 21 of the optical transceiver assembly 2 are inserted into the mainboard 200 and welded with the mainboard 200 to achieve hard connection, and the horizontally extending pins 21 can be connected with the mainboard 200 through pin soft belt to achieve soft connection.

The terminal groove 19 can wrap the conductive sheet 6 inside. The two terminal grooves 19 extend along the axial direction of the adapter body 1, and are spaced apart in the left-right direction and distributed on the left and right sides of the optical transceiver assembly 2. At the same time, the terminal groove 19 is spaced apart from the sliding groove 12 in the left-right direction, and the optical transceiver assembly 2 is spaced apart from the conductive sheet 6 after being installed in the sliding groove 12 and the mounting cavity 11.

[0084] Preferably, referring to Figure 6 As shown, the fixing member 3 is provided with a heat sink 8, and the fixing member 3 can be fixed with the heat sink 8 by injection molding. After the fixing member 3 is fixed with the adapter body 1, the heat sink 8 directly contacts the optical transceiver assembly 2 to dissipate heat from the optical transceiver assembly 2. In this embodiment, the heat sink 8 is in a frame shape and surrounds three sides of the optical transceiver assembly 2 to dissipate heat from the optical transceiver assembly 2.

[0085] Referring to Figure 12 As shown, the application also provides a camera module, which can include a camera cover body 300, and the camera cover body 300 is internally provided with the optical transceiver module described above. The optical transceiver module in this embodiment can adopt any of the optical transceiver modules provided in the above embodiments and realize the corresponding functions, which will not be described here.

[0086] Further, in an embodiment, referring to Figure 12 As shown, the camera cover body 300 includes a camera first cover body 301, and the camera first cover body 301 is internally provided with a receiving cavity 3011 and a plug-in hole 3012. The receiving cavity 3011 and the plug-in hole 3012 are distributed in the camera first cover body 301 along the axial direction of the plug-in hole 3012 and are in communication with each other. 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-in hole 3012 is located in front of the receiving cavity 3011, and the plug-in hole 3012 penetrates the camera first cover body 301 forwardly, and the receiving cavity 3011 penetrates the camera first cover body 301 rearwardly, so that the plug-in hole 3012 and the receiving cavity 3011 penetrate the camera first cover body 301 forwardly and rearwardly. The optical transceiver module is loaded into the camera first cover body 301 from rear to front, and the front part of the adapter body 1 is inserted into the plug-in hole 3012 through the receiving cavity 3011, which facilitates the front part of the adapter body 1 to be connected to other connectors. Meanwhile, the plug-in hole 3012 can position the optical transceiver module in the camera first cover body 301.

[0087] On the basis of the above technical solutions, referring to Figure 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 camera first cover body 301 forms a limiting step 3013 (see Figure 13The limiting step 3013 is matched with the limiting plane 1411. In this embodiment, the first protrusion 141 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. Meanwhile, the bottom of the adapter body 1 can also be provided with a limiting plane 1411. The limiting plane 1411 is a vertical plane. The limiting plane 1411 at the top can be coplanar with or not coplanar with the limiting plane 1411 at the bottom. Since the internal size of the accommodating cavity 3011 is larger than the internal size of the plug-in hole 3012, a step, i.e., the limiting step 3013, is formed at the connection between the accommodating cavity 3011 and the plug-in hole 3012. When the optical transceiver module is inserted into the camera first cover body 301, the limiting step 3013 is attached to the limiting plane 1411 in the front-rear direction, and the optical transceiver module is prevented from moving forward further, thereby limiting the optical transceiver module. In some alternative embodiments, the adapter body 1 can be integrally formed with the camera first cover body 301.

Since the optical transceiver module has been positioned and fixed with the camera first cover body 301 through the adapter body 1 before the fastener 400 is used to fix the main board 200, if the main board 200 is fixed again at this time, there will be a problem of over-positioning, therefore, in this embodiment, the through hole 201 with a slightly larger inner diameter is provided on the main board 200 to cooperate with the fastener 400, and a reserved assembly gap is provided, which can solve the problem that the main board 200 cannot be aligned left and right on the camera first cover body 301, and at the same time, the soft silica gel gasket is arranged at the end of the fixing column 3015, which can absorb the assembly gap and solve the problem that the main board 200 cannot be aligned front and back with the camera first cover body 301.
