Description

Technical Field

[0001] The utility model belongs to the technical field of optical communication module testing, and in particular relates to a pull-out force testing device for optical device pins. Background Art

[0002] Optical communication modules are core components in optical communication systems. They are optoelectronic devices that can realize photoelectric conversion and electro-optical conversion during optical signal transmission. In the process of manufacturing optoelectronic devices (optical devices), the TO pins of optical devices need to be electroplated to improve their conductivity and corrosion resistance. Different electroplating methods can improve the conductivity and stability of the pins. The current test device only tests the conductivity of the TO pins, and does not test the stability of the TO pins.

[0003] In the prior art, a utility model patent with the announcement number CN217237506U discloses a device for testing the welding and pulling out of PCB pins, the device comprising a fixing frame, the bottom of which is welded with legs, the inner wall of which is welded with two groups of columns, and the surfaces of the two groups of columns are slidably connected with a test platform. Through the setting of the locking mechanism, the locking plate only needs to be pulled in two directions, and then the PCB board can be fixed by the elastic force of the first spring and the second spring, without the need to use additional tools, and the PCB board can be quickly disassembled and assembled, and the structure is simple, and with the setting of the adjustment mechanism, the locking plate can be driven to move as a whole through the adjustment plate, so as to adapt to PCB boards of different sizes, and through the setting of the pulling mechanism, the lateral drive of the electric push rod can be converted into the longitudinal drive of the test platform, so that the PCB board can be driven downward by the test platform to achieve pulling, without the need for manual pulling by the staff, thereby improving work efficiency.

[0004] In addition, the invention patent with the publication number CN114323988A also discloses a device for testing the welding pull-out of PCB pins. The pull-out test device is installed at the bottom of the driving assembly and driven to rise and fall by the driving assembly. It includes a contact plate, a shell and an elastic gas storage layer. The elastic gas storage layer is arranged between the contact plate and the shell. When the pull-out test device is driven by the driving assembly to press down the PCB board, the contact plate and the upper end surface of the PCB board are in contact and pressed. When in use, only the PCB board needs to be pressed down to realize the welding strength test of the side and vertical direction of the PCB pins. It can realize integrated fast and efficient testing, and the testing process can more realistically restore the possible pulling environment of the PCB board, making the testing effect more accurate.

[0005] However, the above-mentioned pull-out test device is only applicable to PCB board pins. For TO pins of optical devices, it is also necessary to provide a test device for the pull-out force of the optical device pins without damaging the TO pins. Utility Model Content

By arranging the first clamp 1 and the second clamp 2 relatively, the optical device 6 can be fixed on the second clamp 2, and the pin 5 of the optical device 6 is inserted into the first clamp 1 and tightened with the rotation of the rotating component 4. After the optical device 6 and the pin 5 of the optical device 6 are fixed to the second clamp 2 and the first clamp 1, the second clamp 2 is pulled or lifted to make the second clamp 2 away from the base 3, so as to realize the pull-out force test of the pin 5 on the optical device 6.

[0024] To facilitate the test operation, in a specific embodiment, a boss 7 is provided on the top of the base 3, and the boss 7 can be fastened to the base 3 by a bolt structure, the first clamp 1 is provided on the boss 7, and a thread 8 is provided around the boss 7, and the rotating component 4 is rotatably fixed to the boss 7 by the thread 8. In this embodiment, an optical device insertion groove 11 is provided on the second clamp 2, an opening 12 is provided on the second clamp 2 corresponding to the optical device insertion groove 11, and a threaded fixing pin 13 is provided on the opening 12, so as to achieve the fixation of the optical device 6 and the second clamp 2. When in use, the second clamp 2 is placed above the first clamp 1, and after the optical device 6 and the pin 5 of the optical device 6 are fixed, the second clamp 2 can be lifted upward to start the test.

[0025] In this embodiment, the pin 5 of the optical device 6 is fastened by the cooperation between the first clamping block 1 and the rotating component 4. Specifically, the first clamping block 1 is provided with a plurality of clamping members 9, at least two clamping members 9 can be provided, and the clamping members 9 are in a tapered structure with a small top and a large bottom.

In order to facilitate the insertion of the pin 5 of the optical device 6, in this embodiment, the lower part of the clamping member 9 is fixed to the boss 7, and the upper part of the clamping member 9 extends outward through the rotating component 4.
