Description

Technical Field

[0001] The utility model relates to the technical field of automobile wiring terminals, in particular to a withstand voltage detection tool for automobile wiring terminals. Background Art

[0002] like Figure 6 and 7 As shown, the automobile terminal includes a terminal body 61, and the terminal body 61 includes a terminal main connection end 65. One end of the terminal main connection end 65 extends horizontally and is bent to form a terminal first transfer portion 66. The terminal first transfer portion 66 is bent downwardly and tilted to form a terminal first external connection end 67. The other end of the terminal main connection end 65 extends vertically downward and then continues to bend horizontally and continuously to form a terminal second transfer portion 68 and a terminal second external connection end 69 in sequence. The terminal main connection end 65 is provided with a main external connection hole 70. In order to improve the safety and insulation of the automobile terminal during transmission, a main connection hole 70 is provided in the first transfer portion 66 of the terminal. A first insulating sleeve 62 is provided on the outer sleeve, and a second insulating sleeve 63 is provided on the outer sleeve of the second transfer part 68 of the terminal. Generally, we need to perform a withstand voltage test on the automotive terminal with the first insulating sleeve 62 and the second insulating sleeve 63 before the finished product leaves the factory. In order to confirm the safety of the automotive terminal under normal working voltage and accidental overvoltage, the traditional withstand voltage test is relatively cumbersome. There is no withstand voltage test tooling specifically for the automotive terminal, and only the first insulating sleeve 62 and the second insulating sleeve 63 can be subjected to withstand voltage test separately.

By connecting the first conductive column assembly 31 and the main conductive column assembly 30 with a test current, the first insulating sleeve 62 can be subjected to a withstand voltage test. By connecting the second conductive column assembly 32 and the main conductive column assembly 30 with a test current, the second insulating sleeve 63 can be subjected to a withstand voltage test.

The second upper pressing block 24 docks with the second positioning groove 14 of the insulating sleeve and the second upper pressing block 24 presses on the second insulating sleeve 63. Since conductive glue 18 is adhered to the inside of the second positioning groove 14 and the first positioning groove 17 of the insulating sleeve, as well as on the first upper pressing block 23 and the second upper pressing block 24, the four surfaces of the first insulating sleeve 62 are electrically connected (the four surfaces of the second insulating sleeve 63 are also electrically connected). At this time, the conductive columns 34 contact the upper surface of the terminal body 61, the upper surface of the first insulating sleeve 62, and the upper surface of the second insulating sleeve 63 under the action of the compression springs 35. By connecting the first conductive column assembly 31 and the main conductive column assembly 30 to the test current, the voltage withstand test of the first insulating sleeve 62 can be carried out (since the four surfaces of the first insulating sleeve 62 are already electrically connected through the conductive glue 18, the voltage withstand conditions of the four surfaces can be judged at one time). By connecting the second conductive column assembly 32 and the main conductive column assembly 30 to the test current, the voltage withstand test of the second insulating sleeve 63 can be carried out, and the detection is convenient and fast.
