Let's talk about the common faults of insulators
1. Poor contact
The metal conductor inside the terminal is the core part of the terminal. It transmits the voltage signal from the external wire or cable to the corresponding contact of its matching connector. Therefore, due to unreasonable structural design, wrong material selection, unstable mold, and rough surface, Unreasonable surface treatment processes such as heat treatment and electroplating, improper assembly, poor storage and use environment, improper operation and use, etc, it can cause poor contact between the contact of the contact and the mating part.
2. Poor insulation
The function of the insulator is to keep the contacts arranged in the correct position. Therefore, the insulating parts need to have excellent electrical properties, mechanical properties and process formability, especially with high density, the effective wall thickness of the insulator becomes thinner and thinner. This puts forward more stringent requirements for insulation materials, injection mold accuracy and molding process. Short circuit, leakage, breakdown, low insulation resistance and other insulation defects. The moisture absorption, mildew and aging of insulating materials can be caused by the presence of metal residue, flux and other pollution and moisture on the surface or inside of the insulator, and the formation of ionic conductive channels between organic matter precipitates and harmful gas adsorption film and surface water film.
3. Poor fixation
Insulators not only provide insulation, but also usually provide accurate centering and protection for extended contacts. At the same time, they also have the functions of mounting, positioning and locking on the equipment. Poor fixation may affect the reliability of contact, resulting in instantaneous power failure and serious product disintegration. Disassembly means that when the terminal is inserted, due to materials, design, technology and other reasons, the structure is unreliable, and the abnormal separation of the pins and sockets will cause serious consequences of the interruption of the power transmission and signal control of the control system. Improper selection of the molding process, poor heat treatment, mold, assembly, welding and other processes, and insufficient assembly will cause poor fixation.
In addition, poor appearance caused by peeling, corrosion, bruising, flash, fracture, and rough machining deformation of the plastic shell, poor positioning and locking fit size, poor processing quality consistency, and excessive total separation force are also common. Diseases, frequently-occurring diseases, these faults can generally be found and eliminated in time during inspection and use.
