Types and characteristics of terminals

Terminals are mainly divided into general terminals, connection terminals, test terminals, test connection terminals, insurance terminals, optical isolation terminals, terminal terminals, etc. The following are the characteristics of various terminals:

1. General terminals: suitable for connecting wires or cables inside and outside the screen, and for connecting wires on both sides of the same circuit.

2. Connection terminals: The upper and lower adjacent terminals can be connected through the opening on the insulating base, allowing various circuits to be connected or separated.

3. Test terminal: Generally in the AC voltage circuit, it is convenient to avoid TA lead when connecting the test instrument.

4. Test connection terminals: terminals that can not only provide testing, but also can be used in parallel or separately.

5. Fuse terminal: Used in places where the circuit must be easily disconnected, such as connecting an AC voltage circuit.

6. Optical isolation terminal: equipped with optical isolation components, suitable for opening into the loop.

7. Terminal terminal: a terminal block used to fix or separate different installation units.

In addition, there are also terminals with specific functions, such as tubular wiring terminals, cold-pressed terminals, copper noses, wiring blocks, plug-in terminals, etc., which have unique applications and characteristics in their respective fields.
