Description

Technical Field

[0001] This application relates to the field of testing fixture technology, and in particular to a circuit board testing fixture with a corner positioning mechanism. Background Technology

[0002] Circuit board testing refers to the process of verifying the electrical performance, functionality, and reliability of printed circuit boards. Circuit board testing requires the use of testing fixtures to assist workers in the testing work. Circuit board testing fixtures are special tools used to test the electrical performance and functional integrity of printed circuit boards, and are used to test various parameters of the circuit board to ensure product quality.

[0003] Currently, the relevant circuit board testing fixtures lack multiple corner positioning mechanisms for circuit boards, making it impossible to position circuit boards more stably and quickly, thus affecting the efficiency of circuit board testing. Utility Model Content

A support frame is fixedly connected to the top of the fixture platform, and a movable component is fixedly connected to the top of the support frame. A pressure rod is movably mounted on the inner side of the movable component. A pressure plate is fixedly connected to the bottom of the pressure rod. A threaded hole is provided inside the pressure plate, and a positioning rod is movably mounted on the bottom of the pressure plate. A threaded ring is fixedly connected to the top of the positioning rod, and the threaded ring is threadedly connected to the threaded hole. A telescopic rod is installed on the top of the fixture platform at one end of the support frame. A support plate is fixedly connected to the top of the telescopic rod. A placement groove is provided inside the support plate. A shaft is installed at one end of the support plate, and a limit rod is movably mounted on the periphery of the shaft. A magnetic block is fixedly connected inside the support plate on one side of the limit rod. A sensing probe is fixedly connected inside the fixture platform.

[0017] The following is in conjunction with the appendix Figs. 1-3 This application will be described in further detail.

[0018] This application discloses a circuit board testing fixture with a corner positioning mechanism. (Refer to...) Figs. 1-3A circuit board testing fixture with a corner positioning mechanism includes a pressure rod 1, a fixture platform 8, and a support plate 10. A support frame 3 is fixedly connected to the top of the fixture platform 8, and a movable part 2 is fixedly connected to the top of the support frame 3. The pressure rod 1 is movably mounted inside the movable part 2. A pressure plate 4 is fixedly connected to the bottom of the pressure rod 1. A threaded hole 401 is provided inside the pressure plate 4. A positioning rod 5 is movably mounted at the bottom of the pressure plate 4. A threaded ring 501 is fixedly connected to the top of the positioning rod 5, and the threaded ring 501 is threadedly connected to the threaded hole 401. A telescopic rod 11 is installed on the top of the fixture platform 8 at one end of the support frame 3. The support plate 10 is fixedly connected to the top of the telescopic rod 11. A placement groove 1001 is provided inside the support plate 10. A shaft 601 is installed at one end of the support plate 10. A limit rod 6 is movably mounted around the shaft 601. A magnetic block 1002 is fixedly connected inside the support plate 10 on one side of the limit rod 6. A sensing probe 1 is fixedly connected inside the fixture platform 8. 2. The operator inserts the circuit board into the placement slot 1001 inside the support plate 10, and then pulls the rotating limiting rod 6 to rotate and close along the shaft 601. The end of the limiting rod 6 is made of metal iron and can be magnetically connected to the magnetic block 1002. The limiting rod 6 limits the edge of the circuit board. At this time, the pressure rod 1 is pressed down, which pushes the pressure plate 4 and the positioning rod 5 down to achieve the circuit board being limited from the top. This achieves double positioning of the corners of the circuit board without the need to adjust the position of the circuit board, effectively improving the positioning effect and efficiency. The support plate 10 descends, the telescopic rod 11 retracts, and the sensing probe 12 penetrates the support plate 10 to contact the circuit board. The operator can freely install the positioning rod 5 at a suitable position at the bottom of the pressure plate 4 according to the position of the corner parts of the circuit board, and screw the threaded ring 501 into the corresponding threaded hole 401. This reduces the limitations of the device. The external testing equipment is connected to the sensing probe 12 to cooperate in the testing of the circuit board.

[0019] Reference Fig. 1 A spring 7 is installed on the periphery of the telescopic rod 11, and the inner diameter of the spring 7 is adapted to the size of the telescopic rod 11. The spring 7 can drive the support plate 10 to pull the telescopic rod 11 back to its original position.

[0020] Reference Fig. 2 A guide rod 13 is fixedly connected to the top of the fixture table 8 inside the support frame 3, and the guide rod 13 passes through the pressure plate 4. The guide rod 13 can guide and limit the movement direction of the pressure plate 4, thereby improving the stability of the movement of the pressure plate 4.

[0021] Reference Fig. 1 A fixing member 9 is fixedly connected between the movable part 2 and the support frame 3, and a bolt is movably installed between the fixing member 9 and the support frame 3. The fixing member 9 increases the contact area between the movable part 2 and the support frame 3, and the bolt fixes the fixing member 9 to the support frame 3, thereby improving the stability of the movable part 2 installation.

[0022] Reference Fig. 1 One end of the pressure rod 1 is fixedly connected to a handle 101, which is made of silicone rubber. When the worker holds the handle 101, he pulls down the pressure rod 1, which increases the friction between the worker's palm and the pressure rod 1, making it easier for the worker to press down the pressure rod 1.

[0023] The implementation principle of a circuit board testing fixture with an edge positioning mechanism according to an embodiment of this application is as follows: First, the circuit board is inserted into the placement slot 1001 of the support plate 10. The limiting rod 6 is pulled and rotated around the shaft rod 601 to close, so that the metal iron material at the end of the limiting rod 6 is magnetically connected to the magnetic block 1002. The limiting rod 6 limits the edge of the circuit board. The pressing rod 1 pushes the pressure plate 4 and the positioning rod 5 down, limiting the circuit board from the top. When the support plate 10 descends, the telescopic rod 11 retracts, and the sensing probe 12 penetrates the support plate 10 to contact the circuit board. The positioning rod 5 is fixed to the threaded hole 401 of the pressure plate 4 through the threaded ring 501, and its position is adjustable.
