Uninsulated Wires
Uninsulated wires of sizes 28, 26 & 24 gage plus .5mm and .4mm diameter have been successfully
inserted in the contacts.

A variety of conditions can exist after wire insertion depending on the cable size and number of cables
used. The following shows several cases where single or multiple cables are used per connector. The 10
to 18mm dimension represents the distance range from the 2x5 connector sub-assembly to the cable
jacket that allows the cable tie to fasten to the cable jacket. The positioning of the cables in the insertion
equipment controls the final position of the end of the cable jacket to the connector sub-assembly.
A different condition exists when multiple connectors are assembled to one cable. In this case the cable
jacket must be stripped back to the point that the cable ties can only wrap around a bundle of wires. In
the case of hard wire insulation this method is acceptable but in the case of soft insulation a small piece
of heat shrink tubing may be needed in the area of the cable tie to group the wires and prevent the cable
tie from penetrating the wire insulation. However, each of the contacts has its own wire strain relief and in
most applications the cable strain relief is not needed. The cable assembly designer may have to specify
that the heat shrink tube be slid on each bundle of wires before wire insertion depending on size and
shrink rate of the tubing selected.
