Wiring system The task of the wiring system is to make a reliable mechanical and electrical connection of wires. Weidmüller crimping frame can effectively realize this function. The wire crimping frame is made of quenched hardened and galvanized passivated steel, and the steel screws that can withstand huge torque can firmly compress the wires. The copper conductive sheet is plated with a flexible tin-lead alloy to ensure air tightness, low resistance, and permanent connection with the wire. The following advantages of this wiring system are deeply loved by users and are widely used: large contact surface, high contact pressure, and arbitrarily horizontal contact. With self-locking, anti-vibration and anti-loose functions, test jacks can be installed, no need to maintain the contact point. Absolutely airtight, corrosion-resistant multi-strand wire allows no crimping end, can be directly connected, easy to use, and widely used worldwide. Among them, contact force is one of the basic elements. If there is not enough contact pressure, no matter how good the conductive material is, it will not help. Because, if the contact force is too low, there will be displacement between the wire and the conductive sheet, resulting in oxidation pollution , increasing the contact resistance and causing overheating. Take the WDU 2.5 wire-pressing frame assembly as an example, only 0.8 Nm of torque is applied to the screw to generate an actual contact force of up to 750 N, and the magnitude of this force has nothing to do with the wire cross section. Therefore, the Weidmüller crimping frame has a permanent connection that is not affected by any environment, large contact area, and large contact force.
