Modular Connector - Termination

Termination

Termination of modular connector cables is very similar, regardless of the number of positions and contacts in the plug. To prevent damage to the plug (and the expensive crimp die-set), the crimp tool must be carefully matched to the plug being attached. For example, termination of a cable with an 8P8C plug involves using a hand crimper or crimp machine containing an 8P8C die-set or an A67T standard die-set. An 8P8C crimp die-set usually looks similar to an 8P8C jack, except for the eight teeth lining the top portion of the die. When the tool is operated, the die compresses around the 8P8C plug. As the die compresses, these teeth force the plug contacts down into the conductors of the cable being terminated, permanently attaching the plug to the cable.

There are two sub-types of plug, that differ only in the type of contacts used. One contact is suitable for solid (single strand) copper conductors and the other is suitable for stranded or tinsel wire copper conductors. The crimper may also permanently deform part of the plastic plug body in such a way that it grips the outer sheath of the cable. This helps to keep the plug securely fastened to the end of the cable, by providing strain relief.
