Pin Type Insulated Lugs are electrical connectors with a metal pin and a plastic (PVC/Nylon) insulating sleeve, used to terminate stranded wires for secure, vibration-resistant connections in devices with terminal blocks, engines, or railways, preventing shorts and shock with easy entry and color-coding for different wire sizes.
Key Features & Components:
- Material: Made from electrolytic copper (often tin-plated for corrosion resistance) and insulated with PVC or Polyamide (PA).
- Design: Features a hollow end for wire insertion and a crimp barrel, with a funnel-shaped sleeve (easy-entry) for quick, secure wire insertion.
- Insulation: The colored plastic sleeve (red, blue, yellow) protects against electrical shock and environmental damage, with insulation ratings varying by material.
Purpose: Creates a permanent, low-resistance connection for fine stranded wires in heavy-duty or vibrating applications, like automotive or industrial machinery.
How They Work:
- Wire Insertion: Fine stranded wires are pushed into the barrel.
- Crimping: A crimping tool deforms the barrel, creating a permanent bond with the wires.
- Connection: The pin is then plugged into a terminal socket, providing a reliable electrical contact.
