Three Fatal Failures of Connectors

Connector three fatal failure
　　We use connectors in the process of terminals, more or less will encounter some problems: such as corrosion, scratches, flying edge, rupture, or contact parts of the workmanship is rough, deformation, and other reasons for the appearance of bad, or with the size of the failure; Huicheng Yuan Electronics Co., Ltd. engineers to analyze the common fatal faults of the terminals, summarized in the following three points:
　　1. Poor contact:
　　Causes: unreasonable design of contact parts, the wrong choice of materials, substandard dimensions, or improper plating layer treatment.
　　Consequences: affect the power supply, signal transmission, etc., may lead to a serious failure to transmit.
　　2. Poor fixation:
　　Causes: due to unreliable design, material selection errors, improper selection of molding process, heat treatment, molds, assembly, fusion and other process quality is poor, assembly is not in place, etc.; or sometimes careless careless installation is not perfect, or product durability is limited, such as the number of times too many insertion and extraction.
　　Consequences: the light impact on the contact reliability caused by instantaneous power failure, the serious is the disintegration of the product.
　　3. Poor insulation:
　　Causes: the main reason is due to the connector in the manufacture of improper selection of materials; may also be due to the insulator surface or internal presence of metal excess, surface dust, flux and other contaminants such as moisture, organic materials precipitation 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 a short-circuit, leakage, breakdown, insulation resistance is low, etc. Causes.

　　Consequences: The role of the insulator is to keep the contact parts in the correct position, and make the contact parts and contact parts between the contact parts and the shell between the mutual insulation.
