Products Description

The Clamp-Type Screw Terminal for Circuit Components is a core functional component for securing wire connections in low-voltage circuits. It can be directly integrated into circuit components such as switches, circuit breakers, and fuses, providing a stable and reusable electrical connection point for external wires. Compared to traditional welding and crimping connections, this screw-clamping structure enables on-site wiring and maintenance without specialized tools, and is widely used in low-voltage power distribution and new energy power conversion applications.

Product Advantages

01/

Pre-assembled and integrated delivery eliminates manual assembly steps on the customer's production line, reducing labor hours and defect rates, and is compatible with automated assembly lines. This M5 Zinc Plated Screw Terminal Metal Clamp requires no additional tooling; it is pressed into the pre-drilled slots in the plastic shell for secure installation.

02/

The inner wall of the frame features anti-slip serrations. After tightening the screws, the serrations firmly engage the cable conductors, distributing clamping stress and preventing the cutting of individual copper wires. This significantly reduces the risk of overheating after prolonged power-on, perfectly conforming to the clamping mechanics model of Screw Wiring Frames for Low-Voltage Circuit Breaker.

03/

The surface has a complete electroplated zinc layer, free of defects such as missed plating or pinholes. In coastal salt spray and outdoor humid and hot environments, this layer slows down the oxidation of the steel substrate, preventing the formation of an oxide layer on the clamping surface that increases contact resistance, ensuring a long-term stable power supply for outdoor photovoltaic equipment.

04/

Terminal Cage achieves fully autonomous production, with ample raw material procurement. For long-term project orders, it can lock in raw material inventory, avoiding the risk of stockouts caused by fluctuations in steel raw material prices and insufficient capacity of outsourced factories.

Product Structure Disassembly

Overall Structure

This product features a pre-assembled, integrated structure, composed of two core components: an M5 Zinc Plated Screw Terminal Metal Clamp and galvanized screws. The screws are pre-installed in slots within the frame, allowing for adjustable clamping positions along the axis without falling out, facilitating component assembly and on-site wiring.

Part Details

Terminal Block Clamping Frames: The Terminal Block Clamping Frames feature a one-piece stamped square frame structure with uniform wall thickness. The pre-drilled space accommodates wires of corresponding specifications, and the chamfered opening facilitates wire insertion.
Clamping Screws: Utilizing standard machine threads, the threads of the Socket Parts Cable Metal Clamp Terminal meet ISO standards. The Phillips head design allows for tightening with a universal screwdriver, and the head size accommodates the operating space of conventional tools.
Pre-assembled Structure: The screws of the M10 Electrical Terminal Block are snapped into the frame, allowing free rotation without detaching from the frame. No additional fixing is required, meeting the requirements of automated assembly.

Working Principle

During wiring, the stripped wire is inserted into the frame through the opening. The screw is rotated and pushed in, pressing the wire firmly against the inside of the frame through the screw's end face. Mechanical clamping force ensures stable contact between the wire and the internal conductive components, achieving both electrical connection and mechanical fixation. The structural design of the Terminal Block Clamping Frames ensures even distribution of clamping force, preventing damage to the wires.
