Description

A quick connector for an electrical test line

technical field

The utility model relates to the technical field of electric test line joints, in particular to a quick joint for electric test lines.

Background technique

Electrical test is to determine whether there are quality problems in installation or manufacturing before the electrical system and electrical equipment are put into use, so as to determine whether the newly installed or operating electrical equipment can be put into operation normally. The insulation performance, electrical characteristics and mechanical properties of the single equipment are tested and verified item by item in accordance with the relevant provisions of the standards, regulations and specifications. Through these tests and verifications, it is possible to detect and eliminate in a timely manner when electrical equipment is manufactured and installed. defects, errors and quality problems, to ensure that electrical systems and electrical equipment can be put into normal operation.

In the electrical experiment, the electrical test line is an indispensable part. Generally, the connector of the existing electrical test line is mainly to fix the test lead to the terminal block through the plug-in or pin-type joint for testing. This method is more secure. However, it is necessary to loosen the terminal screws and connect them with the original wires. The operation is cumbersome and the reliability is low. When performing small tests, the workload will increase. If the terminal is damaged, the other is to use the alligator clip-type quick connector to clamp on the terminal fastening screw for testing, but this method is prone to dangers such as falling off, touching other terminals by mistake and causing a short circuit. Therefore, for the above problems, there is an urgent need for a quick connector of an electrical test line.
