Abstract

Various arrangements for insulating terminals against unwanted electrical contact are in wide use. The terminal may be attached to the end of a wire, by crimping, and then insulation is applied as a second operation. This insulation may be in the form of molded parts, shrink tubing, or the like.

Preinsulated Open Barrel Terminals

Various arrangements for insulating terminals against unwanted electrical contact are in wide use. The terminal may be attached to the end of a wire, by crimping, and then insulation is applied as a second operation. This insulation may be in the form of molded parts, shrink tubing, or the like.

To eliminate such a second operation, the illustrated terminal is fabricated from a laminate of conductor material such as brass with a layer of insulation such as plastic prelaminated to one side of the brass. The insulating material should have good adhesion to the conductor, high-impact resistance, forming quality and dielectric strength. Polyvinylchloride is one example.

As shown in the drawing, the insulator layer 10 covers only the outside of the brass connector 12. When the ears 14, 16, 18, 20 of the connector are crimped about a wire, not shown, and an electrical connection is thereby made to the wire, only insulated surfaces of the crimped portion of the connector 12 are exposed around the wire. If the wire is stripped for only the short portion underlying ears 14, 16 and the ears 18, 20 are positioned to clamp over the unstripped insulation on the wire, a protected connection is made.

If desired, the portion of the connector forming the underside 22 of the terminal end 24 can be stripped, or the laminate 10, 12 can be provided initially with this portion as a bare metal edge. In the case of a slip-on terminal, which could be th...
