Pre-Assembled Screw Clamp Terminal
Products Description
The Pre-Assembled Screw Clamp Terminal is an integrated precision electrical connection accessory, pre-assembled at the factory, and can be directly applied to low-voltage electrical equipment such as terminal blocks, circuit breakers, contactors, and fuse holders. This product eliminates the need for secondary on-site assembly, avoids human error, and ensures consistent connection performance across a batch of products. The product, combined with the connector frame and fastening screws, forms a cage-like clamping structure that securely holds copper and aluminium cables without the need for additional crimping tools, making it a standardised and preferred component for electrical wiring connections.
Product Advantages
Structural Integration Advantages
The Screw on Terminals adopts a modular pre-assembly design, with screws, fasteners, conductive clamping frames, and insulating bases assembled and torque-calibrated before leaving the factory. After receiving the product, customers can directly install it onto DIN rails or equipment panels without additional tools for internal component assembly, significantly shortening the production line assembly cycle.
Cost and Delivery Advantages
Leveraging our own manufacturing plant and automated production lines, we have achieved end-to-end control from raw material procurement to finished Steel Cage Screw Terminal Block shipment. This not only ensures competitive factory pricing but also reduces the delivery cycle for standard products to 7–15 working days, with expedited production available for urgent orders.
Quality Consistency Advantages
Each batch of Circuit Breaker Screw Clamp Terminal products undergoes rigorous incoming material inspection, in-process inspection, and outgoing inspection. Key dimensions are measured using CMM coordinate measuring machines to ensure consistency in batch deliveries. PPAP documentation packages are available for automotive electronics and rail transportation customers.
Manufacturing Process
| Stamping | Precision progressive die stamping is used to press and connect the frame, keeping the critical dimensional errors of the Contactor Screw Wire Clamp Terminal within a very small range, ensuring interchangeability of parts. |
| Screw Machining | CNC machining ensures uniform thread specifications and stable torque output for the Fuse Holder Screw Clamp Terminal. |
| Surface Electroplating | Fully automated galvanising production line operation with real-time monitoring of the coating thickness of the Electrical Connection Cage Clamp with screws ensures a uniform protective effect. |
| Integrated Assembly | Automated equipment completes component pre-assembly; 100% torque testing is performed on the finished Screw Fastener Terminals. |
| Finished Product Packaging | Protective packaging is used to prevent damage to the crimped frame during transportation; custom outer box labels can be customised according to customer requirements. |
Industry Application Cases
Low-Voltage Power Distribution Systems
Screw Lug Terminals are widely used in main circuit and control circuit connections in distribution cabinets and boxes.
