What are the types of pcb terminals?
The pcb terminal is a terminal for connecting electrical appliances in a printed circuit board, which can realize electrical connection. So what are the types of pcb terminals? The following editor will introduce the types of pcb terminals.
There are plug-in series terminals, fence series terminals, spring-type printed circuit board terminals, and screw-type terminals.
1.Plug-in series terminals
It is connected by two parts of the plug board, one part presses the wire tightly and plugs it into the other part. One part is pluggable, and the other part will be fixed on the PCB board. The product has a pin pitch of 3.5, 3.81, 5.0, 5.08, 7.5, 7.62 poles and 2-24 wires, which is a popular type at present.
2.Fence series terminals
It can realize safe, reliable and effective connection. It is generally black. It is generally used in equipment with high current and high voltage requirements and has higher insulation protection.
3.Spring-type printed circuit board terminals
There are 2.54mm, 3.50mm, 5.00mm, 7.50mm, 7.62mm and other spacings. It is a new type of terminal using a spring device. Single-core wires can be directly inserted without the assistance of a handle. It is currently widely used in the world’s electrical and electronic engineering industries.
4.Screw-type terminals
The advantages are compact structure, reliable connection, and its structure and design make wiring more convenient and the screw connection more solid. The principle of wire clamp lifting is used to ensure reliable wiring and large wiring capacity. The solder foot and wire clamp of the screw-type terminal are two parts, so that the distance of tightening the screw will not damage the solder joint.
