Abstract

Wire barrel connector 1 can be crimped by a crimping tool to attach it to insulated wire 2 so as to establish a low resistance electrical connection. This is accomplished without weakening wire 2 and without having to remove the insulation prior to attaching the connector. Wire 2 can be as fine as #32 AWG and it can have an insulating coating of a tough varnish or lacquer.

Wire Barrel Connector

Wire barrel connector 1 can be crimped by a crimping tool to attach it to insulated wire 2 so as to establish a low resistance electrical connection. This is accomplished without weakening wire 2 and without having to remove the insulation prior to attaching the connector. Wire 2 can be as fine as #32 AWG and it can have an insulating coating of a tough varnish or lacquer.

Before crimping, connector 1 is U-shaped and has two opposed portions 3 and 4 that extend inwardly towards the inner base of connector 1. Surfaces 5, 6 and 7 are knurled or roughened. During crimping, surfaces 5 and 6 are brought into contact with wire 2. Surfaces 5 and 6 are moved across the surface of wire 2 to scour off the insulation and uncover the bare metal or conductor.

Surface 7 bites through the coating. During the final stages of crimping, connector 1 and wire 2 are squeezed so the resultant connection has a substantially solid cross-section.
