A terminal is a type of connector that is used to facilitate the connection of wires. There are holes at both ends of the wiring terminals, making it convenient for us to insert wires. So when using a terminal connector, it is required that its contact area can transmit circulating current, and the peripheral insulation area should also be insulated reliably. If these two needs cannot be met, various adverse factors are prone to occur. For the convenience of understanding, this article will introduce to you the factors that cause adverse effects on terminal connectors?

Poor contact

The metal conductor inside the terminal connector is the core component of the terminal, which transmits voltage, current, or signals from external wires or cables to the corresponding contacts of the corresponding connector. The contact parts must have excellent structure, stable and reliable contact retention force, and good conductivity, so material selection is also crucial.

Poor insulation

The function of an insulator is to maintain the correct alignment of the contacts and to insulate them from each other, as well as from the shell. Therefore, insulation components must have excellent electrical, mechanical, and process forming properties.

Poor fixation

Insulators not only serve as insulation, but also provide precise alignment and protection for extended contacts. They also have the function of installation positioning, locking and fixing on the equipment. Poor fixation may affect the reliability of contact, resulting in instant power outage. The most serious issue is product disassembly. Disassembly refers to the abnormal separation between plugs and sockets, as well as between pins and sockets, caused by unreliable structure due to materials, processes, and other reasons when terminals are in a plugged in state, which will result in serious consequences such as interruption of power transmission and signal control in the control system.

The above three adverse factors are all related to the internal conductor and external insulation of the terminal. Therefore, when selecting terminal connectors, we should choose high-quality and stable products to facilitate our use.
