Integrated Screw Clamp Terminal
Products Description
An integrated screw clamp terminal is a pre-assembled, integrated electrical connection assembly that combines screws, junction boxes, clamps, or conductive clips. Its core functions in electrical equipment include:
wire securing; current conduction; conductor clamping; anti-loosening connection; and stable contact.
The product is typically installed in:
wall switches; sockets; terminal blocks; circuit breakers; fuses; electrical control modules; photovoltaic electrical equipment;
and other electrical structures requiring external wiring.
The pre-assembly method avoids problems such as missing parts, loose screws, and uneven crimping that occur in traditional manual assembly, making it particularly suitable for modern automated assembly lines and large-scale electrical product manufacturing.
Wide Range of Industrial Applications
High-end wall switches and building electrical systems
Wire Clamp Terminal with Screw provides fast and convenient household wiring connections, ensuring long-term electrical safety.
Industrial-grade wiring switches and contactors
Cope with the frequent vibration environments inside machine tools and automated equipment.
Molded case circuit breakers (MCCBs) and miniature circuit breakers (MCBs)
Provide robust cable connections between the power supply and load sides under high voltage and high current surges.
PV/renewable energy fuses
Provides long-term, reliable connections that withstand high DC voltage (1000V/1500V DC) and extreme outdoor temperature variations.
Production Process and Manufacturing Advantages: From Micron-Level Forming to Full Inspection System
| Precision Multi-Station Cold Forging | The Pre-Assembled Screw Wire Terminal manufacturing abandons traditional, simple stamping and bending. We employ a multi-station precision cold forging machine, using the three-dimensional plastic flow of metal at room temperature to integrally form the complex internal cavity and external contour of the frame. The work-hardening effect not only enhances the mechanical strength of the material but also ensures the density of the frame sidewalls, resulting in extremely high rigidity when subjected to the radial expansion force of the screws. |
| Screw-Free Extrusion Tapping Process | Thread machining is the core technology. We do not use traditional cutting taps but instead use extrusion taps for chip-free tapping. Extrusion taps form threads by cold-extending metal, causing plastic displacement. The metal fiber flow lines of the thread are continuous and unbroken. Threads produced by this process have significantly improved surface hardness and tensile strength compared to cutting threads, fundamentally eliminating the risk of thread stripping. |
| Automated Flexible Pre-assembly Line | We have built a fully enclosed automated pre-assembly workshop. Screws and frames are automatically press-fitted according to the set pre-tightening depth and torque using a precision vibratory feeder and vision recognition system. The equipment not only ensures that the pre-tightening force of each screw is consistent, but also uses a laser displacement sensor to remove any defective Pre-Assembled Screw Clamp Terminal with stuck or misaligned threads, ensuring that every wiring harness delivered to the customer is in a perfectly tightened state. |
