Abstract

The terminal for a small wire has a barrel that is crimped to taper inwardly toward the end of the wire. Even with relatively wide manufacturing tolerances, this configuration gives proper crimping geometry at some region along the length of the barrel. Any excessive crimping occurs only towards the end of the wire beyond the region where mechanical stress can be applied and where adequate electrical contact is established.

Crimped Terminal with Tapered or Stepped for Use with Small Diameter Wire

The terminal for a small wire has a barrel that is crimped to taper inwardly toward the end of the wire. Even with relatively wide manufacturing tolerances, this configuration gives proper crimping geometry at some region along the length of the barrel. Any excessive crimping occurs only towards the end of the wire beyond the region where mechanical stress can be applied and where adequate electrical contact is established.

When a crimped terminal is designed for use with a small diameter wire, the tolerances of the terminal and die areas may be substantially greater than the area of the wire. In this situation it is difficult to establish correct crimping. If the crimping is insufficient, the terminal may not make good electrical contact with the wire. If the crimping is excessive, the wire may be damaged.

In one configuration, this crimp is formed with an even taper that is produced by a tapered crimp die. In another configuration, the crimp is formed as a series of steps of slightly different diameter. The smallest diameter of the taper or the steps is toward the end of the wire.
