Strip wire insulation material is very time-consuming because many connectors for quick Assembly use insulation displacement connector, so that the insulation material needed is not removed from the wire. These general open fork terminals, insulated wires and insulated conductor through the contact form. To make these connections reliably on the line during the General Assembly, the special tool for precisely controlling the application of force. If assembled correctly, thus terminating gas-tight, and life of the final product. A common example used in computer disk drives; multiconductor flat ribbon cables a lot (about 40) each separate wire termination will be slow and error-prone, but insulation displacement connector can terminate all the wires (literally) in one stroke. Another very common use is called to terminate telephone operator on the block.

Insulation displacement connector is typically used for small conductors for signal purposes and low voltage. Carry more than a few amps of power wire more reliably terminated with other means, while "hot tap" information on connectors find some uses added to the existing wiring in car applications.

Plug and socket connector is usually composed of a male plug (usually pin contacts) and the female receptacle (usually the contacts of the Jack), although hermaphroditic connectors exist, such as the original IBM Token Ring LAN connector. Insert the plugs usually have one or more open mating pin of the socket pins. Connection between the mating metal parts must be tight enough to make good electrical connections and complete the circuit. Multi-pin connector, to identify each pin connecting pin out diagrams of the wiring or circuit node is helpful.
