What are the reasons for the damage of the male and female terminal wire?

Male-female butt terminal wires may fail due to various reasons during operation. Common faults include poor contact of the connector, short circuit between wires, open circuit, grounding, etc. So, what are the reasons for the terminal line failure?

There are several reasons for the simple damage to the terminal wire:

1. Partial thinning during actual use, causing local fever, increasing resistance, and accelerating the aging of insulation.

2. Oxidation and rust black spots interfere with conductor joints, increase resistance, and easily age insulation.

3. Bumps or scratches interfere with the mechanical strength of the conductor.

The appearance inspection of the terminal wire is to inspect the appearance of the finished product, semi-finished product or material, and the standard inspection is to review each product according to the various standards stipulated in the product standard.

Layout inspection refers to the inspection of the structure of each component part of the terminal wire. Surface inspection such as the oxidation of copper wire will interfere with the quality of the terminal wire. The standard can directly interfere with the performance of the product, such as the outer diameter of the conductor and its resistance. related;

Insulation thickness and resistance are related to withstand voltage level; strand pitch is related to the softness and firmness of the product. Inspection can reveal the production quality of terminal wires and feel the problems existing in the production process. Therefore, it is said that the control of appearance and layout scale is the guarantee of product performance.
