定义
A mechanical fastening component used in electrical terminal blocks and sockets to securely clamp conductors (wires) against conductive terminals, ensuring reliable electrical contact through controlled compression force. It typically consists of a screw, washer, and clamping plate assembly designed to prevent wire slippage, reduce contact resistance, and maintain connection integrity under vibration and thermal cycling conditions.
工作原理
Works on the principle of mechanical compression: when the screw is tightened, it creates controlled pressure that forces the conductor against the terminal's conductive surface, establishing a low-resistance electrical path while preventing movement that could loosen the connection.
材料
Typically made from brasscopper alloyor stainless steel for corrosion resistance and conductivitymay include nickel or tin plating for enhanced surface propertiesinsulating components often use PA66 (nylon) or other engineering plastics.

常见问题

What is the main purpose of a terminal clamp/screw?

To securely fasten electrical wires to terminal blocks or sockets, ensuring reliable electrical contact and preventing connection failure due to vibration or thermal expansion.

How do I select the correct terminal clamp/screw for my application?

Consider wire size, current rating, environmental conditions (temperature, humidity), material compatibility, and required torque specifications based on manufacturer guidelines and industry standards.

What maintenance is required for terminal clamps/screws?

Periodic inspection for corrosion, verification of proper torque, and re-tightening if necessary due to thermal cycling or vibration. Replacement if signs of wear or damage appear.
