TE Connectivity – CoolSplice Connectors: Connecting Wires Was Never So Easy!

TE Connectivity’s (TE) CoolSplice connectors are designed to connect a pair of discrete wires, or a twin cord cable in line to a pair of discrete wires or twin cord cables. The insulation  displacement, free hanging connectors accept either 18AWG or 20-22AWG stranded or solid wire in unsealed and sealed, color coded configurations.

The TE CoolSplice connectors help eliminate the need to pre-strip the insulation from the wire conductors and provide a visual controlled termination. The push connect buttons provide a more ergonomic wire termination than conventional twist-on-wire connectors/nuts (marrettes). The slim, symmetrical contoured, snag resistant connectors fit through a 16.00mm [0.630] diameter hole or PVC tube.

TE design engineers also put a lot of effort into the ease of use of these connector products. With no training it is possible to make perfect connections and in two simple steps, the termination can be made.
