Plastic Cable Connector

Plastic cable glands (also known as cable connectors, waterproof joints, or locking heads) are critical accessories within electrical connection systems. Through threaded locking and compression via a sealing ring, they achieve axial cable fixation, radial sealing, and protection for equipment cable entry points. Primarily manufactured from nylon (PA6/PA66), these products offer advantages such as excellent insulation, lightweight construction, corrosion resistance, and ease of installation, making them widely applicable in fields including distribution boxes, control cabinets, motors, LED lighting, and automation equipment.

Five Core Advantages
1. High-Level Water and Dust Protection: IP68 Certified
Utilizing an O-ring seal and an internal cable-gripping claw structure, the protection rating reaches IP68 (withstanding immersion in 1 meter of water for 30 minutes without ingress). Simultaneously, it meets IP66 and higher dust-proofing requirements, making it suitable for use in indoor, outdoor, and humid environments.
2. Superior Tensile and Torsional Resistance
Features built-in anti-slip clamping claws (also referred to as an "anti-pull-out structure"). When the cable is subjected to axial tension or torsional forces, these claws tighten their grip on the cable sheath, preventing loosening. Certain models are capable of withstanding tensile forces of ≥100N.
3. Fully Insulating Material: Enhanced Electrical Safety
Constructed from flame-retardant nylon (PA66, UL94 V0/V2 rated), the material is non-conductive and rust-proof, thereby eliminating the short-circuit risks potentially associated with metal connectors. This makes it particularly well-suited for applications with strict insulation requirements—such as power distribution cabinets, rail transit systems, and new energy sectors.
4. Resistance to Oil, Acids, Alkalis, and Weathering
The nylon material exhibits excellent resistance to mineral oils, weak acids and alkalis, and salt spray. The black, UV-resistant variant is designed for long-term outdoor use, ensuring it remains free from cracking or premature aging.
5. Easy Installation and Comprehensive Thread Specifications
Available in a wide range of thread standards—including Metric (M8–M100), PG, G (Pipe Thread), and NPT—the glands come complete with matching locknuts and sealing washers. They can be installed quickly using either bare hands or a wrench, thereby significantly reducing labor costs.
