Screw fixing welding technology terminal

With the advent of modular terminal blocks, screw wiring technology has dominated industrial control systems. Compared to screw connections, other joining techniques do not provide such a large pressing force in such a small space. The screw self-locking system prevents accidental loosening of the connection. The operation is very simple, only a screwdriver is needed to complete the operation of the terminal screws and bridges. Thanks to the high quality of the joint material, long-term reliability is maintained even in harsh environments such as aggressive air. Screw wiring is indispensable in high current applications. The 240mm2 terminal block can carry over 400A of operating current.

Screw terminals are the most widely used terminal blocks in various fields and have withstood the rigors of various environments: whether in the ocean or on the plateau, whether it is tropical high temperature or -40 ° C low temperature, Stendhal's screw terminals are reliable and stable. Working at the ground. Excellent product quality has produced such excellent performance:

All-copper metal parts The screw parts are made of high-strength copper alloy, the current bar is made of electrolytic copper, and the wire clamping body is made of copper alloy which is resistant to stress cracking. The copper metal parts ensure good electrical conductivity and corrosion resistance, and the same copper material as the wire avoids different degrees of thermal expansion due to the difference in thermal expansion coefficient of the material, thus avoiding looseness.

High contact pressure and reliable contact ensure a reliable contact: the lifting cylinder principle ensures a very small contact resistance, the screw self-locking principle prevents the terminal screws from loosening, and the flat clamping body ensures a very thin wire. Clamped

Wires can be used to produce contact pressures up to several hundred Newtons without the need for pre-treatment screw terminals, which reliably compress single, multiple and thin strands without the use of tubular ends and copper crimp ends; Flame-retardant grade VO shell material Insulating shell is made of nylon 6.6 thermoplastic material, which can achieve UL94 standard V0 flame retardant grade, safe and reliable.
