The terminal is a metal piece arranged in the insulating material of the connector. Its function is to guide the wire to make electrical connection with the electronic device. As the accuracy requirements of industrial automation control become more and more strict, the amount of terminal has been increasing, but the wiring There are also some undesirable factors in the use of the terminal. The following Xin explains the three major factors that lead to the failure of the connector terminal of the connector by Pengbo Electronic Technology.

Connector terminal
   The terminal of the connector may have peeling, corrosion, bruising, flashing, cracking of the plastic surface, rough processing or deformation of the contact parts of the contact surface, which may cause poor appearance during use.

1. Poor insulation of connector terminals

The function of the connector terminal insulator is to maintain the correct arrangement of the contact parts, and to insulate the contact parts and the contact parts, and the contact parts and the housing from each other. Therefore, the insulation must have excellent electrical properties, mechanical properties and process forming properties. Especially with the high density and the widespread use of miniaturized terminal blocks, the effective wall thickness of insulators is getting thinner and thinner. This puts more stringent requirements on insulation materials, injection mold accuracy and molding process.

Second, the connector terminal is poorly fixed
  The connector terminal needs to be fixed in a specific position to achieve a stable connection. If the installation is imperfect or the life cycle of the product is insufficient to cause poor fixation, the lighter affects the reliability of the contact and causes a momentary power failure. The serious thing is the product disintegration. Disassembly refers to the abnormal separation between the plug and the socket, the pin and the jack caused by the unreliable structure of the terminal in the plugged state due to materials, design, process and other reasons, which will cause the control system power transmission and Serious consequences of signal control interruption. Due to unreliable design, wrong material selection, improper selection of molding process, poor quality of heat treatment, mold, assembly, welding and other processes, poor assembly will cause poor fixation.

3. Poor contact of connector terminals
   The metal conductor inside the terminal of the connector is the core part of the terminal. It transmits power, signals, etc. to other parts in contact with it. Therefore, the metal conductor inside the terminal must have good conductivity. If the design of the contact parts is unreasonable, the material selection is wrong, the size is not standard, or the plating layer is not handled properly, it will cause poor contact of the connector terminals

Here are three major factors that lead to bad connector terminals.
