The test terminals 6 are symmetrically fixedly installed at positions on both sides of the upper surface of the wiring harness high-voltage tester 1. The two test terminals 6 are electrically connected to the wiring harness high-voltage tester 1. The wiring harness high-voltage tester 1 is electrically connected to the automobile wiring harness through the test terminal 6, so as to facilitate high-voltage testing. A transparent protective cover 2 is rotatably installed on the upper surface of the wiring harness high-voltage tester 1 through a hinge 9. The transparent protective cover 2 is made of a transparent flame-retardant material. Grooves 5 are symmetrically arranged at positions on both sides of the upper surface of the wiring harness high-voltage tester 1. Electric push rods 4 are rotatably installed in the two grooves 5, and the ends of the two electric push rods 4 are respectively rotatably connected to the positions on both sides of the inner wall of the transparent protective cover 2. The transparent protective cover 2 is driven to rotate open or close by the electric push rods 4. A sealing strip 8 is fixedly installed at a position near the edge of the front surface of the transparent protective cover 2. When the transparent protective cover 2 is rotated and closed, the sealing strip 8 on its front surface contacts the upper surface of the wiring harness high-voltage tester 1, thereby sealing the transparent protective cover 2.

[0022] A vacuum pump 10 is fixedly installed inside the wiring harness high-voltage tester 1, and a vacuum hose 3 is fixedly connected to the end of the vacuum pump 10 input pipe, and the end of the vacuum hose 3 is fixedly connected to the outer surface of the transparent protective cover 2, and an activated carbon box 11 is fixedly connected to the end of the vacuum pump 10 output pipe. A smoke sensor 7 is fixedly installed inside the transparent protective cover 2, and the smoke sensor 7 and the vacuum pump 10 are electrically connected.
