Causes of damage to male and female butt terminal wires and how to inspect them?

I. Cause of damage to male and female butt terminal wires?

Male and female butt terminal wires can fail for a variety of reasons during operation. Common failures include poor contact of the plug, short circuit between the wires, disconnection, hitch and so on. Simple formation of terminal line damage for several reasons are as follows: 1, the actual use of local pull thin, causing local fever, increased resistance, accelerate the aging of the insulation. 2, oxidized rust black spots, stirring the conductor joints, increased resistance, simple aging of the insulation. 3, bruises or scratches stirring the mechanical strength of the conductor.

-II. How to properly inspect terminal wires?

The appearance of the terminal line test is to test the products, semi-products or materials of the appearance of the phenomenon, scale test is according to the product standard rules of the various scales to review each product. Layout inspection refers to the layout of the various components of the terminal line engaged in the inspection, appearance inspection such as oxidation of copper wire questions on the quality of the terminal line is disturbed, the scale is the function of the product can be directly disturbed, such as the conductor's outer diameter and its resistance is related. Insulation thickness and resistance are related to the level of voltage resistance. Stranded wire pitch and the product's softness, sturdy level related. Inspection can reveal the production quality of the terminal line, feel the doubts that exist in the production process, so that the pitch control appearance, layout scale is the guarantee of product function.
