LCJQ Series Braided Copper Flexible Connector

The LCJQ series features braided copper flexible connectors (also known as copper braid straps or tress connectors) made from fine copper wire braided into a flexible, high-conductivity strap.

Product Overview

Braided flexible connectors are the most common type of flexible copper connector, widely used for grounding, bonding, and applications where high flexibility is required.

Construction

Braid Structure

• Made from fine copper wires (0.05mm - 0.20mm diameter)
• Multiple strands braided into a flat or round strap
• Available in bare copper or tinned copper
• High strand count for maximum flexibility

Termination Types

• Crimped terminals: Tubular or flat terminals crimped onto the braid
• Bolted ends: Clamped or welded end plates with mounting holes
• Bare ends: Untreated ends for custom termination

Insulation Options

• PVC insulation (general purpose)
• Silicone insulation (high temperature)
• Glass fiber sleeve (extreme heat)
• Heat-shrink tubing (environmental protection)

Key Advantages

Maximum Flexibility

Braided construction allows for easy bending and routing in tight spaces and around obstacles.

Superior Vibration Resistance

The braided structure absorbs vibration and movement, making it ideal for dynamic applications.

Cost-Effective

Braided connectors offer excellent performance at a competitive price point compared to laminated connectors.
