A wire-wrapped termination is made by coiling the wire around the sharp corners of a .025 inch square receptacle post. By bending the wire around the sharp corner, the oxide layer of both surfaces is broken, revealing an oxide-free surface. This provides clean metal-to-metal contact between the wire and the post. The minimum number of turns is based on wire gauge and the type of wrap. A standard wrap coils only the bare wire around the post.
A modified wrap coils the wire and a portion of the insulation. The modified wrap increases the ability to withstand vibration.
