Description

Technical Field

[0001] The utility model relates to the technical field of camera module production and manufacturing, in particular to a test fixture for a coaxial line type camera module. Background Art

[0002] The current vehicle-mounted camera modules, because of the long transmission distance required, mostly use coaxial cables as the transmission solution, which has long-distance transmission and can ensure signal stability. As the plug between the camera module and the whole machine, the Fakra connector is usually used. The Fakra connector uses high-quality materials and precise manufacturing processes, has good electrical and mechanical properties, and can maintain stable operation in various environments. When it is necessary to test the coaxial camera module, the longer the coaxial cable is, the larger the space occupied by the test fixture will be, making it difficult to manage the test fixture.

[0003] In view of the above, a test fixture for a coaxial line type camera module is proposed, so as to realize a retractable design of the test fixture. When the test fixture is not in use, the test fixture can be reduced to a minimum size to reduce the occupied space. Utility Model Content

[0022] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.

[0023] See also Figure 1 , Figure 2 and Figure 3 As shown, a test fixture 10 for a coaxial line type camera module includes: a camera module 100, a plug connector 200 and a module positioning and shrinking member 300, the camera module 100 includes a module body 110, a coaxial line 120 and a connector 130, one end of the coaxial line 120 is connected to the module body 110, and the other end of the coaxial line 120 is connected to the connector 130; a socket 210 is provided on the plug connector 200, and the connector 130 is plugged into the socket 210; the module positioning and shrinking member 300 includes a positioning and shrinking frame 310 and a guide rail 320, one end of the guide rail 320 is installed on the plug connector 200, the positioning and shrinking frame 310 is slidably connected to the guide rail 320, and a positioning groove 311 is provided on the positioning and shrinking frame 310, and the module body 110 is located on the positioning groove 311.

[0024] It should be noted that when the camera module 100 needs to be tested, the module body 110 in the camera module 100 is first placed in the positioning groove 311, and the module body is positioned through the positioning groove 311. Then, the positioning and shrinking frame 310 needs to be moved along the guide rail in a direction away from the plug connector 200 to match the length of the coaxial line to avoid the coaxial line being squeezed during the camera module test and affecting the signal transmission; after the position of the positioning and shrinking frame 310 is adjusted, the connector 130 on the camera module 100 is plugged into the socket 210, and the camera module can be powered on and work to realize the test operation. When the test is completed, the camera module 100 is removed, and the positioning and shrinking frame 310 is moved along the guide rail 320 in a direction close to the plug connector 200, so as to shrink the test fixture to the smallest size to reduce space occupation.

[0025] It should also be noted that, in one embodiment, one end of the guide rail 320 can be fixedly mounted on the plug connector 200, and only the positioning and retraction frame 310 is moved to adjust the position; in another embodiment, one end of the guide rail 320 is slidably disposed on the plug connector 200, that is, a guide hole is also provided on the plug connector 200, and the guide rail 320 is slidably disposed in the guide hole, so that bidirectional movement of the positioning and retraction frame 310 and the plug connector 200 can be achieved.

[0026] Specifically, the socket connector 200 includes a PCB board 220 (circuit board) and a strip plug 230, and the socket 210 and the strip plug 230 are respectively arranged on the PCB board 220. That is, the socket and the strip plug are respectively connected to the PCB board, wherein the socket is used to connect the connector, and the strip plug is used to connect and work with the test fixture and the test tooling to realize the test operation. It should also be noted that a mounting seat is provided at the bottom of the PCB board 220 for installing the guide rail.

[0027] In one embodiment, an adhesive 312 is provided on the positioning groove 311. When the module body 110 is placed in the positioning groove 311, the adhesive 312 is used to position and fix the module body 110. In this way, the module body 110 is positioned by the adhesive 312 to assist in fixing the module body 110, thereby preventing the module body 110 from shaking during the test and affecting the test results. Preferably, the adhesive 312 is a double-sided foam adhesive with foam on it, so it can play a buffering role on the module body 110 and prevent the module body 110 from being damaged by bumps.

[0028] Furthermore, the depth of the positioning groove 311 is greater than the thickness of the adhesive member 312. In this way, it can be ensured that both the positioning groove 311 and the adhesive member 312 can play a role in positioning and fixing the module body 110.

[0029] Preferably, the positioning groove 311 is in a square structure. The shape of the positioning groove 311 matches the shape of the module body 110 .

[0030] In one embodiment, two guide rails 320 are provided, and two guide holes are provided on the side wall of the positioning and shrinking frame 310, and each guide rail 320 is slidably inserted into each guide hole. Providing two guide rails 320 can ensure the stability of the movement of the positioning and shrinking frame 310, for example, the two guide rails 320 are provided parallel to each other.

[0031] In one embodiment, each guide rail 320 is in a square structure, and the guide hole is in a square structure. The square structure guide rail 320 can play a limiting role relative to the cylindrical structure guide rail 320 to prevent the positioning and shrinking frame 320 from rotating relative to the guide rail.

[0032] In one embodiment, positioning protrusions are respectively provided on both side walls of the guide rail 320, and limiting grooves are also provided on both side walls of the guide hole. When the guide rail slides through the guide hole, the positioning protrusions are accommodated in the limiting grooves. The positioning protrusions and limiting grooves can further improve the movement stability of the positioning and shrinking frame 310.

[0033] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
