Products Description

clamp style terminal strips are electrical connection devices that secure wires using screws or elastic clamping structures. They consist of an insulating base and conductive metal components, using clamping force to firmly hold the wires in place, achieving safe, low-impedance current transmission.

Compared to traditional plug-in terminals, clamping terminal blocks offer higher mechanical strength and vibration resistance, maintaining stable connections even under frequent vibration or high-temperature environments. They are ideal wiring solutions for industrial equipment, energy systems, rail transportation, and energy storage systems.

Product Features and Core Advantages

Stable Clamping Structure for Long-Term Conductivity

Utilizing a high-precision threaded or spring clamping mechanism, it provides continuous and uniform pressure distribution, preventing loosening due to vibration or thermal expansion and contraction.

Even under high temperature, strong vibration, or long-term operating conditions, the wires maintain a secure connection, significantly reducing maintenance costs and downtime risks.

High Conductivity and Low Contact Resistance

Conductive parts are made of high-purity copper alloy or tin-plated brass, precision stamped and surface electroplated, effectively reducing contact resistance and improving current-carrying capacity.

Maintaining stable electrical performance during long-term operation provides continuous and reliable energy transfer for industrial equipment.

Safe Insulation Design for Comprehensive Protection

Using flame-retardant engineering plastics (PA66, PBT, or PC alloy) as the insulating base material, it possesses high dielectric strength and excellent heat and aging resistance.

Even in humid or dusty environments, it ensures electrical isolation and safe operation.

Modular Design for Greater Installation Flexibility

Customizable to various customer needs, supporting multiple conductor cross-sectional areas. The modular structure facilitates quick assembly and replacement.

Suitable for flexible configuration and installation in control cabinets, junction boxes, and large power distribution systems.

Easy Maintenance and Strong Adaptability

The Clamp Terminal Block structure eliminates the need for soldering or special tools during assembly; wiring can be completed with just a screwdriver.

Simultaneously supports various wire types, including single-core wire, stranded wire, and wires with terminals, meeting diverse operating conditions.

Technological and Manufacturing Advantages

Precision Machining & High Consistency Quality

Apollo possesses comprehensive mold development and metal stamping capabilities, completing the entire process-from mold design and stamping to surface electroplating-in-house.

Conductors utilize CNC stamping and fully automated riveting processes, ensuring precise dimensions and consistent performance for every Screw Connector Block.

Rigorous Material Selection and Certification System

All metal and plastic raw materials comply with RoHS and REACH environmental standards.

Conductors use C2680, C3604 brass, or T2 pure copper, guaranteeing excellent conductivity and mechanical strength; insulators use UL94V-0 flame-retardant materials, passing high-temperature aging and dielectric strength tests.

Advanced Electroplating Process

Multi-layer electroplating technology (tin plating, nickel plating, or silver plating) enhances corrosion resistance and conductivity, resulting in a uniform, burr-free surface treatment that effectively prevents oxidation and arc corrosion, extending Electrical Screw Terminal lifespan.

Automated Assembly and Testing

High-precision positioning and consistent locking force are achieved through automated assembly lines.

The entire process is equipped with online resistance detection and torque monitoring systems to ensure that all Screw Clamp Type Terminals leaving the factory meet stringent conductivity and clamping standards.

Production Process of clamp style terminal strips

Structural Design Highlights

Reinforced Copper Conductor Structure

The internal conductors utilize thick copper strips or multi-layer composite conductor structures, enhancing overall current-carrying capacity and resistance to mechanical shock.

Smooth surface and rounded transitions prevent wire cuts.

Dual Clamping Mechanism

Some models feature a dual clamping structure (upper pressure plate + lower conductor), creating a bidirectional enveloping force during clamping, improving contact area and mechanical stability.

Insulated Barrier Design

Thickened insulating barriers are used between each Clamp Type Terminal Block to effectively prevent creepage and breakdown, ensuring safe operation of the system under high-voltage conditions.

Optimized Mounting Holes and Markings

The base is equipped with standardized mounting holes, compatible with DIN rails or panel mounting.

Numbered or laser-marked markings are also provided for easy on-site identification and maintenance.
