This video demonstrates how to attach a two-piece BNC crimp-on connector to RG59 coax cable for use in CCTV camera installations. Let’s get started.
On my workbench I have the
BNC crimp-on connector that I’ll be using. You can see that this is the two-piece type which consist of a barrel or sleeve and the BNC connector. This is a standard piece of RG59 Siamese coax cable. For tools I have a TL70 crimping tool, a TL22 cable stripper, and a pair of plier cutters.
First step is to slide the barrel piece of the connector onto the RG59. You must slide the small end of the barrel first. Next I will use the cable stripper to remove the plastic jacket of the RG59. I am only using one of the blades in the TL22. The other is completely disengaged. I insert the coax cable onto the tool so that it is about flush with the end or just slightly sticking out. Then I give it four or five spins around the cable. I have the blade on the cutter adjusted just right so that none of the copper shielding under the jacket is cut. Then using a pier of pliers I remove the plastic jacket.
You can see here that all of the copper braiding was left intact. Next I peel back the copper braiding so that none is left touching the white insulator. Next I will use the other cutter that is built into the TL22 to trim the white insulation and expose the center core of the coax. I make sure that none of the cooper braiding is left touching the cable core. You want the length of the exposed core of the cable to be about the same length as the part of the connector that it will slide into. Mine was just a little bit too long so I’m going to trim off the end a little bit.
Next I slide the BNC connector onto the coax core. You want the bottom of the connector to be snug against the insulation of the cable. Then push the copper braiding over the shaft of the connector. Next I slide the sleeve over the cooper braiding and onto the shaft. The copper shielding is used to properly ground the connection, and it also ensures that the crimp is secure. Last, I place the shaft of the connector onto the largest setting of the TL70 crimp tool and crimp down all the way. If the copper braiding is exposed more than you’d like you can trim it using wire cutters or a razor blade. There we have a nice secure BNC connector on our coax cable.
