What are the common failures of energy storage harnesses?

I. What are the common failures of energy storage wiring harness?1. Poor contact The metal conductor inside the energy storage wiring harness is the core part of the terminal, which transmits the voltage, current or signal from the external wires or cables to the contacts corresponding to its mating connector. Medical harnesses are used to transmit information signals or operating signals in bunches of wires, cables in general. Therefore, the contact must have excellent structure, stable and reliable contact holding force and good electrical conductivity. As a result of structural design of contact parts unreasonable, material selection error, mold instability, poor processing dimensions, surface roughness, heat treatment plating and other surface treatment process is unreasonable, improper assembly, storage and use of harsh environments and improper operation and use of contact parts in the contact parts and with the parts caused by poor contact. 2. poor insulation of the problem of the insulator's role is to enable the contact parts to maintain the correct position of the arrangement, and make the Contact parts and contact parts, contact parts and shell insulation between each other. Therefore, the insulator must have excellent electrical properties, mechanical properties and process molding performance. Especially with the high-density, miniaturized energy storage harness is widely used, the effective wall thickness of the insulator is getting thinner and thinner. This puts more stringent requirements on the insulating materials, injection mold precision and molding process. Due to the insulator surface or internal presence of metal excess, surface dust, flux and other contaminants damp, organic material precipitates and harmful gases adsorption film and the surface of the water film fusion to form ionic conductive channels, moisture absorption, mold, aging of insulating materials, etc., will result in short circuits, leakage, breakdown, insulation resistance is low and other insulation defects. 3. poorly fixed problem of the energy storage wiring harness insulator is not only to play the role of insulation, but also usually for the outstretched contact parts to provide the insulation, the insulation material is not only to provide the insulation, but also to provide the insulation materials, the insulation material is not only to provide the insulation material. Usually also for the outstretched contact parts to provide the center and protection, but also has the installation of positioning, locking fixed in the function of the equipment. Fixed poorly, the light impact on the contact reliability caused by instantaneous power failure, serious is the product disintegration. Disintegration refers to the energy storage harness in the plug state, due to materials, design, technology and other reasons resulting in unreliable structure caused by the plug and socket between the pins and jacks between the abnormal separation, will cause the control system power transmission and signal control interruption of the serious consequences. Due to unreliable design, wrong material selection, improper selection of molding process, poor quality of heat treatment, molds, assembly, fusion bonding and other processes, assembly is not in place and so on will cause poor fixing. In addition, due to plating peeling, corrosion, bruising, plastic shell flying edge, rupture, contact parts processing roughness, deformation and other reasons caused by the poor appearance, due to the positioning of the locking fit dimensions are too poor, processing quality consistency is poor, the total separation force is too large reasons caused by the poor interchangeability, is also a common problem. These kinds of faults can generally be found in the energy storage harness inspection and use of the process of timely elimination.
