Description
Screwless PCB Terminal Block (Pitch: 5.0mm)
Product Overview
The 5.0mm Screwless PCB Terminal Block is a high-efficiency, wire-to-board connector engineered for rapid, tool-less electrical terminations. Utilizing an advanced internal spring-clamp (tension sleeve) mechanism, this terminal block eliminates the need for traditional screw-tightening, drastically reducing assembly time and completely removing the risk of screws loosening over time due to mechanical vibration or thermal expansion.
Designed for direct through-hole soldering onto printed circuit boards (PCBs), it features an easy-access finger actuator or integrated push-button lever on top. Technicians can instantly open the clamp, insert a stripped solid or stranded wire, and release to establish a permanent, gas-tight electrical connection with high retention force.
Key Features
-
Tool-Less Spring Clamp Connection: Features a heavy-duty stainless steel spring leaf that grips wires instantly upon release, cutting wiring assembly and field maintenance times in half.
-
Vibration-Proof & Maintenance-Free: The continuous tension applied by the spring clip ensures a constant, uniform clamping force, making it highly reliable in high-vibration industrial environments.
-
Interlocking Modular Design: Constructed with precision side-grooves that allow individual 2-pin or 3-pin segments to slide and lock together seamlessly, creating custom-length multi-position terminal strips.
-
Standard 5.0mm Pitch spacing: Features industry-standard 5.0mm ($0.197\text{ inch}$) pin spacing, fitting perfectly into commercial PCB footprints, power supply layouts, and prototyping boards.
