Step 3
Feed the cable into the plug, and crimp the connector, as shown in Figure 5-78.
When inserting the cable, check from the side or bore of the plug to ensure that the cable is completely
seated in the plug.

5.1.3.6 Checking the Appearance of Contact Strips
Context
To ensure proper contact between the crimped wires and the wire conductors, the heights
and sizes of the contact strips must be standard and the same.
The contact strips must be parallel to each other, with an offset of less than ± 5°. The top
margin of a strip must be parallel to the axis of the connector, with an offset of less than
± 10°.
To ensure conductivity, the surface of the contact strips must be clean.
The contact strips must be in good contact with the RJ45 socket. The plastic separators
must remain intact and be aligned.
The contact strip blade must extend beyond the ends of the wires. The ends of the wires
must be in contact with the edge of the RJ45. The distance between them must be less
than 0.5 mm (0.02 in.).
Procedure
Step 1
Hold the crimped connector, with the front side facing you, and check whether the contact
strips are of the same height. The height should be 6.02 ± 0.13 mm (0.237 ± 0.005). If a
measuring tool is not available, you can compare the connector with a standard connector.
