PCB Terminal Blocks

Connectwell Industries offers an extensive range of PCB Terminal Blocks to meet all electronic connection needs. These terminal blocks are available in a variety of pitches, ranging from 3.5 mm to 15 mm and are suitable for wire sizes from 0.5 to 35 sq.mm. The current ratings for the same are ranging from 6 A-125 A at 300-600 V respectively. These terminal blocks have reputed approvals and certifications like CSA, VDE and UL that verifies the quality levels the company offers to its customers.
Connection methods in PCB terminals:
1. Wire Protector Clamp – This is the most economical system for wire termination; in this case the screw on being tightened moves down over the wire protector, holding the wire in place. Due to the presence of wire protector there is no damage done to the wire being terminated.
2. Rising Clamp – This is the most reliable type of connection method; in this case on tightening of the screw, the clamping yoke moves up towards the screw tightening the wire being terminated. As there is a current bar in place between the screw and the wire, there is no damage done to the wire.
3. Screwless Spring Clamp – This is the fastest connection method for terminating wires into terminal blocks. Connection can be made by simply stripping the wire of its insulation to the recommended length and inserting it into the terminal where the wire is held against the current carrying part by a pre-stressed clamp.
