Common Failure Conditions Of Cable Terminals

cable lugs The internal conductor is the core component of wire lugs, which transmits the voltage, current or signal from the external cable or cable to the contact piece corresponding to the matching connector. electrical lugs The contact piece must have excellent structure, stable and firm contact persistence and excellent conductive function. Due to the unscientific design of the contact piece structure, wrong selection of raw materials, unstable mold, processing size error, rough surface, unscientific surface processing such as heat treatment process and electroplating, improper assembly, storage and application harsh environment and improper use, the contact parts of the contact parts will form poor contact.

Poor insulation
The function of the insulator is to keep the contact piece in the proper position arrangement and to insulate the contact piece from the center of the contact piece and the center of the contact piece from the shell. terminal lugs The insulator must have excellent electrical function, mechanical energy and processing technology molding function. Especially with the widespread use of high-density and miniaturized copper lugs, the effective thickness of the insulator is getting thinner and thinner. This will put forward more stringent standards for insulation materials, precision molding methods of plastic molds, etc. Due to the presence of unnecessary metal on the surface or inside of the insulator, dust on the surface, flux and other pollutants, organic material separation and harmful substance adsorption film merge with the surface water film to form an ion conductive channel, moisture, mildew, aging of insulation materials and other factors, short circuit, leakage, breakdown, poor grounding resistance and other poor insulation conditions will be caused.

Poor fixation
Insulators not only play an insulating role, but also usually provide precise centering protection for the extended contact parts, and also have the function of equipment positioning and locking and fixing on the equipment. Poor fixation, at the least, affects the contact stability and causes power outage in an instant, and the more serious is brand crash. Crash refers to the abnormal separation of the center of the plug and the socket, the center of the terminal and the jack due to the material, design, processing technology or other reasons when the Aluminum Cable Lug structure is not firm, which will cause Compression Cable Lug to cause serious damage to the power transmission and signal control interruption of the automatic control system. Poor design, incorrect material selection, improper molding method, poor quality of heat treatment process, mold, equipment, welding and other processes, and inadequate equipment implementation will all lead to poor fixation.
