B. Contact Crimp Features
Figure 3 shows a typical contact as it should appear after crimping. Although a pin contact with insulation
barrel is shown, the requirements apply equally to socket contacts and to contacts not having an insulation
barrel.
1. Crimp Location
For optimum crimp effectiveness, the crimp must be within the area shown and must meet the crimp
requirements provided in Figure 3. Effective crimp length shall be no less than the dimension given in
Figure 3 and is defined as that portion of the wire barrel, excluding bellmouth(s), fully formed by the
crimping tool. Instructions for adjusting, repairing, and inspecting tools are packaged with the tools.
2. Conductor Extension
The conductor may extend beyond the wire barrel to the maximum shown.
3. Wire Barrel Seam
The wire barrel seam must be closed with no evidence of loose wire strands visible in the seam.
4. Conductor/Insulation
The conductor and insulation must both be visible in the area between the insulation barrel and the wire
barrel.
5. Bellmouth
Front and rear bellmouths shall be formed and adhere to the dimensions given.
6. Cutoff Tab
The cutoff tab shall be cut to the dimensions shown.
7. Burrs
The cutoff burr shall not exceed the dimensions shown.
8. Flash
The wire barrel flash shall not exceed the dimensions shown in Section X--X.
