PCB Terminal Block Classification

Mar 22, 2023

1. Pluggable terminal blocks
The plug-in terminal blocks have needle pitches of 3.50 mm, 3.81 mm, 5.00 mm, 5.08 mm, and 7.62 mm, with a number of digits of 02-24p. Sockets fixed with screws can be provided for matching and seismic connection. The plug uses side to side connection technology, which means that the screw direction and the wire incoming direction are straight.


2. Screw type terminal blocks
The structure and planning of screw type terminal blocks have strengthened the features of convenient wiring and reliable screw connection; Compact structure, reliable links, with its own advantages; Utilize the lifting principle of the wire clamp body to ensure reliable wiring and large wiring capacity; The welding leg and the wire clamp body are divided into two parts to ensure that the distance when tightening the screw does not transfer to the welding spot and damage the welding spot; Robust and reliable housing, needle pitch.


3. Spring type printed circuit board terminals
Spring type printed circuit board terminals have needle pitches of 2.50 mm, 3.50 mm, 5.00 mm, 7.50 mm, 7.62 mm, etc. Single core wires can be inserted directly without the assistance of a handle, but smaller wires can be clamped by opening the clip with a handle; There is no button standard, making it possible to significantly reduce the height. When retracting the wire, it is easy to remove the wire by pressing it down with a screwdriver; Most spring type terminals are assembled one by one; Wiring methods are extremely suitable for use in communication systems, lighting systems, monitoring systems, and building wiring; Various wiring directions are advantageous for assembly in a narrow space, with arbitrary combination of contact numbers and convenient operation, suitable for high-density wiring requirements.


4. Fence type terminal blocks
Fence type terminal blocks are designed for power applications and incorporate a flip over type clear safety cover. Barrier wire ends that can allow for clutter or wear to prevent electrical short circuits between the orientation of the same terminal block and adjacent components. It can achieve safe, reliable, and effective connection, especially in the application environment of large current and high voltage, which is widely used.
Fence type terminals are interconnections that contain metal straps and connectors or screws that allow for wire termination and bonding.
