Medium Carbon Steel Circuit Breaker Wiring Frame
Products Description
The Medium Carbon Steel Circuit Breaker Wiring Frame is an integrated connection structure made primarily of medium carbon steel, formed by stamping and pre-assembling with fastening screws. Its core structure includes:
High-strength stamped junction box body
Precision-matched threaded screw assembly
Wire clamping contact area
Anti-loosening structural design (such as embossing, elastic structure, or limit design)
This structure is primarily used to achieve a stable connection between external wires and internal conductors of electrical equipment, combining mechanical locking and conductivity functions.
Technical Features and Manufacturing Process: Full Control from Raw Materials to Finished Products
Precision Multi-Station Stamping
The Screw Clamp Terminal is stamped using multi-station continuous die forming, ensuring that the angle and dimensional tolerance of every bend are within the micrometer level, thus guaranteeing a perfect fit with the circuit breaker housing.
High-Precision Thread Rolling
The Stamping Screw Terminal Blocks are rolled instead of cut, ensuring that the metal fiber flow lines are not cut, greatly enhancing the shear strength of the threads.
Automatic Pre-Assembly Technology
Utilizing a self-developed automatic assembly machine, the screw insertion depth is precisely controlled, ensuring that each set of Wire Connector Electric Terminal Blocks does not fall off during transportation and is easy to start during assembly.
Multi-Alloy Coating
Environmentally friendly zinc-nickel alloy or trivalent chromium passivation is used, providing not only extremely high salt spray test indicators (up to 96-500 hours), but more importantly, significantly reducing contact resistance and controlling temperature rise.
Application Advantages: Real-world Verification in Harsh Operating Conditions
| Photovoltaic Combiner Boxes and Fuse Holders | In photovoltaic systems, direct current lacks a zero-crossing point. Once an arc occurs due to poor contact, Rail Terminal Block is extremely difficult to extinguish and can quickly ignite a fire. Our medium-carbon steel nickel-plated junction boxes, with their extremely high resistance to arc erosion and stable clamping force, have become the standard for photovoltaic connector bases and fuse terminals in such scenarios, safeguarding the safety of the entire photovoltaic array. |
| Molded Case Circuit Breakers (MCCBs) and Automatic Circuit Breakers (ACBs) | As the "main artery switches" of industrial power distribution, MCCBs have a compact internal space but carry enormous currents. Pre-assembled junction boxes maximize space utilization, not only reducing the overall size of the circuit breaker but also providing rock-solid mechanical support under short-circuit current surges, preventing the terminals from being "blown open" by the immense electromagnetic force. |
| Industrial Terminal Blocks and Control Cabinets | In humid, dusty industrial environments, the dense galvanized layer of the junction box effectively blocks the intrusion of corrosive media. The pre-assembled design significantly improves wiring efficiency when dealing with dense cabling, eliminating the need for electricians to carefully place washers with tweezers and greatly shortening the assembly cycle of the control cabinet. |
Detailed Showcase: Quality Hidden in the Micrometers
Ram-Free Edge Treatment
High-frequency polishing ensures the wiring frame does not damage the wire insulation and will not cut the fingers of installers.
Thread Consistency
Torque consistency deviation of each screw is controlled within an extremely small range, supporting automated torque monitoring systems in electrical factories.
Identification Engraving
Supports laser engraving of batch numbers or material markings on the side of the frame, meeting international engineering traceability requirements.
