Terminal is a kind of connector, which comes into being for the convenience of wire connection. Usually it consists of insulating parts, conductive parts, welding feet and so on. For spring terminal, there are shrapnel. The terminal is a technological design, and the experts of the company recommend that it be used in the following situations:
1. Because of debugging, maintenance and other factors, the conductors in this position need to be disassembled and assembled frequently. For example, two wires, sometimes need to be connected, sometimes need to be disconnected, then they can be connected with terminals, and can be disconnected at any time, without having to weld them together or twist them together, it is very convenient and fast.
2. An electrical box or circuit board and so on, as a whole, need to be electrically connected with other external circuits. The PCB terminal is used on the circuit board. When the circuit breaks down, the conductor can be easily detected, so that the conductor can not be disassembled from the circuit board time-consuming and laborious.
3. Equipotential points at the same place need to be connected with a larger number of wires. There are holes at both ends of the terminal to insert wires. Screws are used to fasten or loosen wires. They are suitable for a large number of wires interconnection. In the power industry, there are special terminals, terminal boxes, which are covered with terminals, single-layer, double-layer, current, voltage, ordinary, breakable and so on.
4. It is not convenient to connect with screw terminals because of its large diameter. Plug-in terminals can be connected to large diameter wires by using wire-pressing frames, and the protective wires are not easy to be damaged.
5. The contact area of the electric connection should be increased because of the large current. TB series high current terminal can meet the needs of large current connection.
6. Multiple wires need to be connected to the same terminal. Because the same terminal has multiple jacks, it is convenient for wires to access.
It has been nearly a hundred years since the invention of wiring terminals. From the earliest combination terminals to various plug-in, direct welding, fence, spring terminals and even bare terminals, a perfect electrical interface technology system has been formed in the field of connectors. Its scope of use has also expanded to rail transit, security lighting, elevator power control, medical devices and other fields, a variety of situations. In view of the convenient installation and stable electrical performance of the terminal, it is gradually gaining the trust of more customers.
