pcb four corner screw terminal

Short Description:

The PCB four-corner screw terminal is a reliable and compact solution for secure wire-to-board electrical connections. Designed for stability and ease of installation, this terminal features a square or rectangular base with screw positions located at each of the four corners, ensuring firm mechanical fixation and excellent conductivity.
Constructed from high-conductivity brass or copper alloy with tin or nickel plating, it offers low contact resistance and strong corrosion protection. The four-corner mounting design provides enhanced mechanical strength, preventing terminal shift or detachment under vibration or repeated use, making it ideal for industrial controls, power modules, HVAC systems, and automotive electronics.
This type of terminal allows for easy wire insertion and screw tightening using standard tools. It is compatible with both solid and stranded wires, supporting a range of wire gauges. The screw-type connection ensures long-term reliability and resistance to loosening, even in high-vibration environments.
The terminal can be soldered or press-fitted directly onto the PCB, with optional insulation barriers or covers to meet high-voltage and safety standards. With compact dimensions and a low-profile design, it is suitable for space-constrained layouts while maintaining high current-carrying capacity.
Customized versions are available in different sizes, thread types, plating options, and mounting configurations to suit specific application needs. Whether used for power distribution, signal control, or ground connection, the PCB four-corner screw terminal delivers stable performance and easy integration into modern circuit board assemblies.
