Example text

As you close the tool, a ratcheting gear locks the jaws. To open the jaws, press the leaver (shown in Figure 2-19) forward and the tool will spring open. The slots for the sleeve and center pin crimping slots are also seen. A common RG-58 BNC connector is seen in Figure 2-20. The center pin is to the left, the sleeve to the right. A small hole in the center pin indicates that this pin can be soldered onto the center wire. Figure 2-20 Once the type of cable and connector have been decided on, you will need to know what length the sheath, shield, inner insulator and center conductor will need to be cut to.

Figure 2-24 Figure 2-25 This is only one style of connector among the hundreds that are available. No matter the type you work with, always: 1) have the data sheet for the connector available, 2) never damage any part of the RF cable, particularly the shield and center wire, 3) do not distort the inner insulator by crimping the sleeve too hard, 4) be sure the center pin extends out sufficiently but not too far. Figure 2-26 This is a commercially available RF cable stripper. You open the unit by pressing on the knurled lever, insert the cable to the stop block, and rotate in the direction indicated on the tool.

Jaws for other sizes can be installed. If you make a mistake with the crimpers (crimper locked with the sleeve misaligned) in the center of the figure, you will have to release a gear to get them to open. As you close the tool, a ratcheting gear locks the jaws. To open the jaws, press the leaver (shown in Figure 2-19) forward and the tool will spring open. The slots for the sleeve and center pin crimping slots are also seen. A common RG-58 BNC connector is seen in Figure 2-20. The center pin is to the left, the sleeve to the right.
