Description

Wire harness conduction detection device

technical field

The utility model relates to electrical testing, in particular to a wire harness conduction detection device.

Background technique

Wire harnesses have been widely used to connect components of existing electrical appliances. The wire harness refers to the contact piece terminal punched from copper and the wire and cable crimped, and the outside is molded with an insulator or a metal shell, etc., and is bundled with a wire harness to form a connected circuit assembly.

In order to ensure the safe and reliable use of the wiring harness, before the wiring harness is put into use, a continuity test is usually carried out to judge whether the continuity of each line in the wiring harness is qualified, so as to detect and eliminate poor contact (open circuit, instantaneous broken), poor insulation (short circuit) and assembly errors and other unqualified failure products to reduce the defect rate of finished wire harnesses.

However, the existing detection devices are generally bulky, cumbersome, not easy to carry, and require a lot of manual intervention, complicated operation, and inconvenient to use.

Utility model content

In view of the above-mentioned shortcomings of the prior art, the purpose of this utility model is to provide a wire harness conduction device for solving the problems in the prior art.

In order to achieve the above purpose and other related purposes, the utility model provides a wire harness conduction detection device, which includes a housing, a wire harness conduction test circuit is installed in the housing, and a signal reminding device connected in series in the circuit and an electrical connection Test probes at the poles of the circuit.

Further, the signal reminding device includes a buzzer and a luminous tube.

Further, the front end of the test probe has a rebound protection structure.

Through the above technical scheme, the utility model has the following technical effects:

The utility model has the advantages of simple design, convenient operation, easy portability, low cost, strong economy and practicability, and can effectively improve the efficiency of the operator in detecting the conduction performance of the wiring harness loop. At the same time, because the front end of the test probe has a springback protection structure, it can effectively avoid the phenomenon that the terminal of the wire harness connector is damaged during the test process.
