[0002] Automotive terminal blocks are core components used to achieve electrical connections in automotive circuits. Made of conductive materials, they are fixed to wires through processes such as crimping and welding. Automotive terminal block withstand voltage testing fixtures are specialized equipment for testing the insulation performance of automotive wiring harness terminals. By integrating conductive post assemblies, positioning grooves, and clamping mechanisms, they can quickly apply high voltage to multiple contact surfaces of the terminal insulation sleeve and test its withstand voltage stability, ensuring that the terminals do not break down or leak current under high-voltage environments. Their design typically includes a worktable, transmission device, and testing module, supporting batch testing and adapting to different terminal specifications. They are widely used in the quality control stages of automotive wiring harness production.

[0003] Traditional withstand voltage testing fixtures lack protective features. During high-voltage testing, if the terminal block performance is poor, electric sparks may be emitted. If these sparks strike the worker's face, they can cause significant injury, resulting in poor safety. Therefore, those skilled in the art provide an automotive terminal block withstand voltage testing fixture to address the problems mentioned in the background. Utility Model Content

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Please see Figures 1-5 As shown, this utility model provides a technical solution: a pressure resistance testing fixture for automotive terminals, including a pressure resistance testing fixture body 1, a rubber support strip 11 fixedly installed on the front of the pressure resistance testing fixture body 1, a protective mechanism 2 provided on the top of the pressure resistance testing fixture body 1, and a support mechanism 3 provided on the top of the pressure resistance testing fixture body 1.

[0023] The protective mechanism 2 includes a strip frame 21, which is fixedly installed on the top of the pressure testing fixture body 1. A connecting bolt 22 is threaded onto the outer wall of the strip frame 21. A transparent protective cover 23 is movably inserted into the inner cavity of the strip frame 21. The threaded end of the connecting bolt 22 movably abuts against the outer wall of the transparent protective cover 23. Side plates 24 are fixedly installed on both sides of the transparent protective cover 23, and support plates 25 are fixedly installed on the sides of the side plates 24. A protruding frame 26 is fixedly installed on the top of the transparent protective cover 23. The testing equipment connected to the pressure testing fixture body 1... The cable can be introduced into the inner cavity of the transparent protective cover 23 from the bottom of the side plate 24. The transparent protective cover 23 has a circular through hole on the side, through which the user can put their hand and then perform a withstand voltage test on the terminal block inside the inner cavity of the transparent protective cover 23. The transparent protective cover 23 is made of transparent plastic, which is convenient for the user to observe and can block possible electric sparks, thus improving safety. The transparent protective cover 23 can be disassembled and cleaned. To disassemble, loosen the connecting bolt 22 and then pull the transparent protective cover 23 out of the inner cavity of the strip frame 21.

[0024] As one implementation method in this embodiment, please refer to Figure 3 As shown, the protective mechanism 2 also includes a hollow plate 27, which is fixedly installed on the top of the pressure testing fixture body 1. A cooling fan 28 is fixedly connected to the back of the hollow plate 27, and an air filter 29 is detachably connected to the back of the cooling fan 28. A hose 291 is fixedly connected to the front of the hollow plate 27, and a hollow plate 292 is fixedly connected to the end of the hose 291 away from the hollow plate 27. A nozzle 293 is fixedly connected to the bottom of the hollow plate 292. The cooling fan 28 is controlled to work, which can absorb the air filtered by the air filter 29, and then deliver it through the hollow plate 27 and the hose 291 to the inner cavity of the hollow plate 292. The air is then output from the nozzle 293 to the inner cavity of the transparent protective cover 23, so that the inner cavity of the transparent protective cover 23 is filled with room temperature air, avoiding the problem of continuous heat accumulation during testing and ensuring the testing effect. The hollow plate 27 and the hollow plate 292 are used for communication, and there are no other structures inside them.

[0025] As one implementation method in this embodiment, please refer to Figure 3 As shown, the hollow plate 292 is movably inserted into the inner cavity of the raised frame 26. A limiting handle 294 is fixedly installed on the top of the hollow plate 292. A magnetic block 295 is fixedly installed on the inner wall of the limiting handle 294. The magnetic block 295 is magnetically connected to the top of the raised frame 26. The raised frame 26 is made of iron alloy. In the initial state, the limiting handle 294 is supported on the top of the raised frame 26, and the magnetic block 295 is magnetically attached to the raised frame 26. When disassembling and cleaning the transparent protective cover 23, the hollow plate 292 can be pulled out from the top of the raised frame 26 for easy operation.

[0026] As one implementation method in this embodiment, please refer to Figures 4-5 As shown, the support mechanism 3 includes a support block 31, which is fixedly installed on the top of the pressure testing fixture body 1. An annular seat 32 is fixedly installed on the top of the support block 31. A turntable 33 is rotatably connected to the inner wall of the annular seat 32. Through the connection between the annular seat 32 and the turntable 33, the user can rotate the terminal block fixed on the support mechanism 3 so that different sides of the terminal block face the user's visible surface, which facilitates the testing work.

[0027] As one implementation method in this embodiment, please refer to Figures 4-5 As shown, a first support arm 34 and a second support arm 35 are fixedly installed on the side of the turntable 33. A threaded rod 36 is threadedly connected to the inner wall of the second support arm 35. When testing the terminal block, the terminal block is placed against the first support arm 34, and then the threaded rod 36 is manually rotated to make the threaded end of the threaded rod 36 abut against the terminal block, thus achieving the function of fixing it. The terminal block is strip-shaped, and by clamping and fixing one end of the terminal block in the air, it is convenient to test the connection of the cable.

[0028] As one implementation method in this embodiment, please refer to Figures 4-5 As shown, a support member 331 is fixedly installed on the side of the turntable 33, and an elastic member 332 is fixedly installed on the outer wall of the support member 331. A clamping member 333 is fixedly installed at the end of the elastic member 332 away from the support member 331. The clamping member 333 movably abuts against the side of the annular seat 32. In the initial state, the elastic force of the elastic member 332 causes the clamping member 333 to fit tightly against the side of the annular seat 32, thereby achieving the function of locking the rotation angle of the turntable 33 inside the annular seat 32.

[0029] As one implementation method in this embodiment, please refer to Figures 4-5 As shown, a sliding handle 334 is fixedly installed on the outer wall of the clamping member 333. The sliding handle 334 is slidably connected to the support member 331. If it is necessary to adjust the clamped terminal, the sliding handle 334 is pulled away from the annular seat 32, and the turntable 33 can be rotated to adjust the position of the terminal.

[0030] Working principle: In use, the terminal block is attached to the first support arm 34, and then the threaded rod 36 is rotated manually to make the threaded end of the threaded rod 36 abut against the terminal block, thus fixing it. If the clamped terminal block needs to be adjusted, the sliding handle 334 is pulled away from the annular seat 32, which will rotate the turntable 33 to adjust the position of the terminal block. The test cable connected to the withstand voltage test fixture body 1 can be introduced into the inner cavity of the transparent protective cover 23 from the bottom of the side plate 24. The test cable is connected to the terminal block, and then the withstand voltage test fixture body 1 can be operated to perform withstand voltage test on the terminal block. The transparent protective cover 23 is made of transparent plastic, which is convenient for users to observe and can also block possible electric sparks, improving safety.
