The terminal is generally composed of a spring piece, a conductive part and an insulating part (plastic case). When wiring, push the screwdriver into the square hole on the right side of the molded case, and push the screwdriver upward to give the shrapnel a downward pressure. The square hole of the spring piece can be Align with the wire frame hole of the conductive member, and then insert the wire from the round hole of the molded case to enter the conductive member to realize the connection between the wire and the terminal. After the wire is connected, the terminal plug is matched with the socket fixed on the circuit board. Connect, you can realize the function of transmitting signals to the outside of the board.
It should be pointed out that when the socket of the terminal block is connected with the plug, the soldering feet (or conductive parts) in the socket can be in seamless contact with the conductive parts in the plug, thereby ensuring good electrical conductivity. Similar to the wiring process, use a screwdriver to press the shrapnel down and directly pull the wire out of the conductive member.
Terminals are often exposed to a variety of environmental factors, such as during transportation and storage, during manufacturing, during installation, repair, and use by end customers. These environmental factors can be understood as established conditions, specifically Divided into temperature, humidity, corrosion, pollution, internal and external conditions and human factors. It is also necessary to define the duration of exposure to changing conditions in these environmental factors.
Warehousing, high-current terminals have different storage environments, from controllable clean, heated or air-conditioned, wet warehouses, offices or factories to uncontrollable environments. In the case of heat, humidity or corrosion, the service life of the terminal will be seriously affected. In these uncontrollable environments, the weldable storage life is greatly reduced by the increase of oxidation, corrosion and intermetallic cooperation; the surface and function of the metal parts are affected by rust, patina and other forms of corrosion. Plastics as insulating materials are also affected by degradation in flexibility, strength, and shape.
