PCB Spring Terminal Block Introduction

The PCB spring terminal block adopts the cage spring and leaf spring wiring technology, which can be used interchangeably with the PCB screw terminal block. PCB spring terminal blocks with different pitches from 2.5mm to 10.0mm, using highly reliable elastic material that is resistant to shock, easy to match, and simple to assemble. 





The pre-stressed spring is opened using a screwdriver so the conductor can be inserted into the insertion space through an opening in the spring leg.  The conductor is pulled against the current bar under the spring force when the screwdriver is removed. The ferrule and single-strand wires can be inserted directly without handles, and smaller wires can be secured by using the handle to open the clips. Due to the direction and alignment of the wires, these blocks are suitable for use with small space and can be combined in any numbers. 

SUN is professional China terminal block manufacturers and pleased to present high-quality PCB spring terminal blocks. This range of spring-type plugs provides a quick and easy way for installers in the field to mate wires without the use of special tools.
