Electrical Cage Terminal For Terminal Zinc Plated
Products Description
The Electrical Cage Terminal for Terminal Zinc Plated features a mechanical clamping design comprising three core components:
1. Screw-based clamping system
A high-strength screw provides a secure axial clamping force to lock the conductor in place.
2. Cage terminal structure
An internal elastic or semi-elastic metal cage structure generates a uniform clamping force under pressure, ensuring stable contact between the conductor and the conductive surface.
3. Conductive terminal body
Serving as the core path for current flow, it facilitates the electrical connection and carries the electrical current.
Operating Principle
As the screw is tightened, the cage structure undergoes elastic deformation, uniformly clamping the conductor against the surface of the conductive terminal. This creates a stable, low-impedance electrical connection, thereby ensuring reliable current transmission.
Manufacturing Advantages and Production Processes
Premium Raw Materials
We select high-conductivity copper alloys or high-quality carbon steel as base materials, balancing electrical conductivity with mechanical strength.
01
Precision Machining
Terminal cages are formed through an integrated stamping and bending process, while screws are manufactured using cold heading and thread rolling technologies to ensure thread precision and strength.
02
Surface Treatment
Multi-stage zinc plating combined with passivation creates a uniform, wear-resistant protective layer, significantly enhancing resistance to salt spray and humidity.
03
Automated Pre-assembly
Specialized assembly equipment ensures the precise fit of screws and cages, eliminating human error, while simultaneous torque and continuity testing is performed.
04
Comprehensive Quality Control
From raw material intake to finished clamp terminal dispatch, we implement multiple rounds of random inspections and performance verification, including clamping force tests, mating cycle tests, and environmental simulation assessments.
05
Detail Showcase and Quality Control Philosophy: Engineering Craftsmanship in Miniature
Zero-Burr Commitment
Following the stamping and bending of the frame, all edges that come into contact with wires or operators undergo deburring. This ensures not only a smooth finish but also prevents sharp edges from severing fine strands of multi-strand copper wire, thereby preserving the effective conductive cross-section.
Consistent Screw Retention Force
High-precision mold control ensures uniform pull-out resistance at the clamp-style terminal strips' engagement point. The screw slides smoothly within the frame without binding or dislodging during intense vibration, providing a smooth, "damped" tactile feel.
Smooth Thread Engagement
Screwing the fastener into the frame's internal threads involves no noticeable resistance spikes or excessive play. This is achieved through the precise matching of internal thread forming and external thread rolling processes; consequently, when customers use electric screwdrivers on assembly lines.
Batch Consistency in Plating Color
The visible zinc plating exhibits a uniform, consistent color, free from mottling, discoloration, or uncoated spots. This reflects the stability of our plating process while ensuring a premium, consistent appearance for the interior of the end-user equipment.
Application Advantages: Covering the Full Spectrum of Low-Voltage Electrical Applications
Wall Switches and Wiring Switches
Serving as the standardized interface for wire entry in switch products, the pressure clamp terminal block directly determines the user's wiring experience and long-term operational safety.
01
Molded Case Circuit Breakers (MCCBs) and Miniature Circuit Breakers (MCBs)
The screw clamp type terminals are a core fastening component at the line-in and line-out terminals; their clamping stability directly impacts the circuit breaker's temperature rise characteristics and the reliability of its protective functions.
02
Photovoltaic (PV) Fuses and Combiner Boxes
In PV systems, terminal clamps must withstand harsh outdoor environments characterized by wide temperature ranges (-40°C to 125°C), high humidity, and salt spray. Galvanized steel terminal clamps demonstrate excellent weather and corrosion resistance in these applications.
03
Industrial Power Distribution and Control Equipment
In devices such as relays, contactors, and Steel MCB Terminal Cages, terminal clamps act as standardized connection interfaces, facilitating rapid and reliable on-site wiring.
