Wire Connector Electric Terminal Block
Products Description
This Wire Connector Electric Terminal Block is a high-reliability fastener designed specifically for electrical connection applications. Utilizing a one-piece metal stamping and thread rolling process, it reliably secures and electrically conducts wires, making it a key component in wall switches, molded case circuit breakers, photovoltaic fuses, and other devices.
Product Functions and Technical Features
| High-Pressure Clamping Structure | As a Pressure Clamp Terminal Block, its metal frame and threaded components provide continuous and stable clamping force, avoiding the risk of overheating and power failure caused by loose wires. |
| Multi-Scenario Adaptability | Supports Terminal Screw Combination design, compatible with single-strand and multi-strand soft/hard wires, adapting to connection requirements of different wire diameters. |
| Anti-Corrosion Coating Treatment | The surface of the Screw Clamp Type Terminals is treated with hot-dip galvanizing or Dacromet coating, maintaining good conductivity and mechanical properties even in humid and high-dust environments. |
Manufacturing Process and Quality Control
Manufacturing Process:
Precision stamping integral molding; the Terminal Screw Combination frame has no weld points, resulting in higher mechanical strength.
Thread rolling process for internal threads, achieving a thread accuracy of 6H, ensuring stable torque.
Automated plating production line, resulting in uniform plating thickness and strong adhesion.
Quality Control:
Fully automated production line ensures dimensional accuracy and consistency of the Clamp Screw for Circuit Breaker.
100% electrical performance testing (continuity, withstand voltage, insulation).
Passes salt spray test, insertion and extraction life test, and temperature rise test.
Clamp Screw for Contactor is ISO 9001 quality management system certified and complies with RoHS and REACH environmental requirements.
