Description

Technical Field

[0001] The utility model belongs to the technical field of wire harness electric inspection jigs, and in particular relates to an electric inspection jig for automobile wire harnesses. Background Art

[0002] Wire harnesses have been widely used to connect electrical components. Wire harnesses refer to components that are formed by crimping contact terminals made of copper materials with wires and cables, and then plastic-pressing insulators or adding metal shells on the outside to form a wiring harness to connect circuits. After production, the wiring harness needs to be tested for continuity by a monitoring station. The automotive wiring harness is an important part of the vehicle's electrical system, which contains a large number of wires and connectors. In the process of automobile production, the continuity test of the wiring harness is an indispensable link to ensure the normal operation of the circuit. Traditional wiring harness continuity test methods usually use tools such as multimeters, but due to the large number of wiring harnesses, one wiring harness takes a long time, and multimeter testing is prone to test confusion.

[0003] To this end, a vehicle wiring harness continuity detection fixture with the announcement number "CN220207692U" includes a detection platform and a detection bracket, a detection plug-in 1 and a detection plug-in 2 installed on the detection platform. The detection bracket is movably provided with a fixture, a receiving cavity is provided on the fixture, and a water pen located in the receiving cavity is provided on the fixture. The pen head of the water pen extends from the fixture and faces the detection plug-in 1. The detection plug-in 1 and the detection plug-in 2 are both provided with a plug slot for connecting with the wiring harness, and a plug connector is installed in the plug slot, and an energized wire is connected between the two plug-in heads. The wire is electrically connected to an electric cylinder, and the electric cylinder is installed on the detection bracket, and the piston rod of the electric cylinder is fixedly connected to the fixture. It is convenient to detect the continuity of the automobile wiring harness.

[0004] However, for the above-mentioned automobile wiring harness continuity detection jig, although the electric cylinder pushes the water pen tip to move in the direction of the detection plug-in through the clamp, and the water pen tip extends into the plug-in slot through the marking port, there are still the following obvious defects during use: and in the above-mentioned jig detection process, since the wiring harness end has a connector for connecting the device, the connector is only placed in the positioning clamp slot for positioning, and the automobile wiring harness will bend upward or downward during the detection, which will cause the connector of the wiring harness to loosen and detach from the clamp positioning slot, making it impossible to complete the wiring harness continuity test at one time, which will affect the detection progress of the automobile wiring harness.
