What are the types of terminals | Electrical Terminal Connectors




The terminal block is a common connection accessory product in the industrial automation industry. It has a wide range of types and complete functions. It has an absolute advantage in the field of wire connection and signal transmission. The types of terminal blocks include UK terminal blocks, European terminal series, plug-in terminal series, transformer terminal blocks, building wiring terminals, fence terminal series, spring terminal series, track terminal series, through-wall type Terminal series, photoelectric coupling terminal series, 110 terminal, 205 terminal, 250 terminal, 187 terminal, OD2.2 ring terminal, 2.5 ring terminal, 3.2 ring terminal, 4.2 ring terminal, 2 ring terminal, 6.4 Ring Terminals, 8.4 Ring Terminals, 11 Ring Terminals, 13 Ring Terminals Flag Series Terminals and Jacket Series, Various Ring Terminals, Tube Terminals, Terminals, Copper Strip Iron Strip (2-03, 4 -03, 4-04, 6-03, 6-04) etc.

Commonly used classification methods in terminal blocks:

(1): According to the country: There are Chinese-style terminals, European-style terminals, and American-style terminals.

(2): According to the purpose: there are guide rail terminal blocks, printed circuit board terminal blocks, automatic fall-off separation terminal blocks, through-wall terminal blocks, airport electrical connectors, radio frequency electrical connectors, etc.

(3): According to the structure: threaded connection, bayonet (quick) connection, card lock connection, push-pull connection, direct plug connection, etc.

(4): According to the terminal connection form of the contact body, it is divided into: crimping, welding, winding; screw (cap) fixing;

(5): With the development of the electronics industry, the scope of use of terminal blocks is increasing, and there are more and more types. In addition to PCB terminals, the most widely used terminals include hardware terminals, nut terminals, spring terminals, and so on.
