The terminals are usually made up of shrapnel, conductive parts and insulation (plastic shell). In connection, the screwdriver is introduced into the square hole of the right side of the plastic shell and the screwdriver is lifted up and a downward pressure is given to the bullet. The square hole of the piece can be aligned with the wire frame hole of the conductor, and then the wire is inserted from the hole of the plastic shell to enter the conductor. The connection between the wire and the terminal is realized. After the wire is connected well, the terminal plug is connected to the socket fixed on the circuit board, and the function of the transmission signal of the circuit board can be realized. It is necessary to point out that when the socket of the terminal line is connected with the plug, the welding pin (or conductive piece) in the socket can be in seamless contact with the conductive part in the plug, thus ensuring good electrical effect. The process of retreating is similar to that of the wiring process. The conductor can be pulled out.

Wire Connectors Terminal Supply are usually faced with a variety of different environmental factors, such as in the process of transportation and storage, during the process of manufacturing, in the process of installation, maintenance, and the use of terminal customers. These environmental factors can be understood as established conditions, specific to temperature, humidity, corrosion, pollution, internal and external conditions and human factors. It is also necessary to define, in these environmental factors, the duration of changing conditions. Warehousing, large current terminals are different in storage environment, from controllable clean, heated or air-conditioned, wet warehouses, offices or factories to the non controlled environment. The service life of terminals will be seriously affected by heat, humidity or corrosion. In these uncontrolled environments, the welding storage life will be due to oxidation and corrosion.

The intensification of the interaction between metals is greatly reduced; the surface and function of metal devices are affected by rust, copper green and other forms of corrosion, and plastics used as insulating materials will also be affected by the degradation of flexibility, strength, and shape.
