Connector Onto a Cable

Installing crimped connectors on your networking cables is a job you can easily do yourself, whether attaching connectors on coaxial cable or unshielded twisted-pair (UTP) cable (often called Ethernet cable).
 
This guide will show you how to crimp the connectors on both types. Before you begin, be sure to read any wiring instructions that come with your connectors.

WHAT YOU NEED FOR THIS PROJECT

MATERIALS

1
Strip the coaxial or UTP cable

• Use wire cutters to cut and square off the end of the cable.
• Use wire strippers to remove ½ inch of the cable’s cover to expose the bare copper center.
• Use your fingers to expose 1/8 inch of braid and foil by pinching and pulling off a small piece of the outer jacket.

For UTP cable, strip ½ inch down from the end using cable strippers, and then carefully trim off the trip cord.

• Slip the ring over the end of the cable.
• Use your fingers to bend all of the braid back along the outside of the cable as evenly as possible.

 • For UTP cable, untwist each pair of wires down to the sheathing. If you’re working with CAT-6 wire, cut the center core down to the cable end.
• Lay out the wires side by side in this order: white-orange, white-green, blue, white-blue, green, white-brown, brown.
• Trim all the wires to the same length, ½ to ¾ inches from the sheath.

Attach the connector

• Push the end of the cable into the F connector so the connector tube goes between the foil and outer housing of the cable. Push the end until the white insulator is flush with the bottom of the connector.
• Slide the crimp ring over the bottom of the connector.

For UTP cable, insert the wires in the order specified in Step 2 into the RJ-45 plug. The cable sheath should extend into the plug by about ½ inch and will be held in place by the crimp.

• Trim any loose wires.
• Cut the copper core wire flush with the end of the connector.
• Pull on the connector to make sure it is firmly attached.
• Repeat the steps to attach a connector on the other end of the cable.

For UTP cable, make sure the wires are in the right order, extend to the front of the plug and make good contact with the metal bases in the RJ-45 plug, and repeat the same steps to attach a connector on the other end of the cable.
