Terminal is a kind of connector, which came into being to facilitate wire connection. Usually composed of insulating parts, conductive parts, solder feet, etc., for brass terminals, there are also shrapnel. The terminal block is a technological design, the Terminal Supplier recommends to consider using it in the following situations:
1. The wire at this position needs frequent disassembly and assembly due to factors such as debugging and maintenance. For example, two wires need to be connected sometimes, and sometimes they need to be disconnected. At this time, they can be connected with terminals and disconnected at any time without having to weld or twist them together, which is very convenient and quick.
2. An electrical box or circuit board, etc., as a whole, needs to be electrically connected with other external circuits. The PCB terminal is used on the circuit board, and the wire can be easily detected when the circuit fails, and it will not be time-consuming and laborious to remove the wire from the circuit board.
3. The same potential point needs to be connected with a larger number of wires. Brass Terminals have holes at both ends to insert wires, screws are used for fastening or loosening, and are suitable for a large number of wire interconnections. In the electric power industry, there are special terminal blocks and terminal boxes, which are full of terminal Layered, double-layered, current, voltage, ordinary, breakable, etc.
4. The wire diameter is large and it is not convenient to connect with screw terminals. The plug-in terminal block is connected with a crimping frame, which can be connected to a large wire diameter and protects the wire from damage.
5. If the current is large, it is necessary to increase the contact area of the electrical connection. TB series high-current terminal blocks can meet the needs of larger current connections.
6. Multiple wires need to be connected to the same terminal. Because the same terminal has multiple jacks, it is convenient for wire access.
It has been nearly a hundred years since the invention of the Terminal Block. From the earliest combined terminal to the various plug-in, straight-welded, fence-type, spring-type terminals and even bare terminals, there has been a complete development in the connector field. Electrical interface technology system. Its scope of use has also been expanded to many fields, such as rail transit, security lighting, elevator power control, medical equipment, and many other situations. In view of the convenient installation and stable electrical performance of the terminal block, it is gradually gaining the trust of more customers.
