定义
A terminal block or connector is an electromechanical component used to create secure, reliable electrical connections between wires and current sensors (CTs). It provides a modular interface for connecting multiple conductors, facilitating easy installation, maintenance, and troubleshooting in industrial electrical systems.
工作原理
Terminal blocks work by providing a clamping mechanism (e.g., screw, spring, or insulation displacement) that secures stripped wire ends to conductive metal strips or bars. This creates a low-resistance electrical path, ensuring reliable current transmission from the sensor to monitoring or control equipment while preventing loose connections that could cause signal loss or safety hazards.
材料
Housing: Thermoplastic (e.g.PA66PBTPC) with UL94 V-0 flame retardancyContacts: Copper alloy (e.g.brassphosphor bronze) with tinsilveror gold plating for corrosion resistance and conductivityInsulation: Rated for voltages up to 600V and temperatures from -40°C to 105°C.
Pitch
5mm to 10.16mm
Mounting
DIN rail (TS35/TS32), panel, or PCB
IP Rating
IP20 for standard, IP67 for sealed versions
Wire Size

常见问题

What is the difference between screw and spring clamp terminal blocks?

Screw terminals use a tightening screw for connection, ideal for high-vibration environments but require torque control. Spring clamps use a spring mechanism for tool-free, quick installation with consistent pressure, suitable for frequent maintenance.

How do I select a terminal block for a current sensor?

Consider current rating (match sensor output), voltage rating, wire size, environmental conditions (e.g., moisture, temperature), and mounting type (e.g., DIN rail). Ensure compliance with standards like IEC 60947-7-1.
