and management
This section describes attaching cable connectors (ring terminal or RJ connector) to cables.
Connectors, cables, and tools to use might vary by vendor. Figures in this section are for illustration
only.

Assembling a cable

Use professional tools and devices and follow the correct steps when you attach a cable connector
to a cable.

Prerequisites

Examining the cable
If there is visible dirt on the cable surface, clean it before assembly.
Examine the appearance of the cable. If any of the following conditions exists, do not use the section
of the cable:
•
The surface of the cable has an obvious bulge, dent, defect, or scratch.
•
The wired shield is incomplete or fractured.
•
Brittle cracks appear after you lightly shake or rub the cable.
Examining the connector
Examine the connector. If any of the following conditions exists, do not use the connector:
•
The connector has obvious damage, cracks, rust, or rust spots.
•
The plating layer of the pins on the RJ-45 connector is off or obviously unevenly plated.
•
The pins on the RJ-45 connector are damaged, missing, broken, or bent.
•
Foreign objects or conductive substances, such as metal chips, exist in the space where the
pins of the RJ-45 connector are located.

Restrictions and guidelines

When you assembly a cable, pinch the connector instead of pulling or stretching the cable.
When you cut a cable or strip the insulation sleeve, follow these restrictions and guidelines:
•
The length of the cable should allow for the loss of length during processing.
•
Wound a long cable into a coil, and tie the coil with a rope or wrapping film. The inner diameter
of the bobbin must be greater than 20 times the outer diameter of the cable.
•
After cutting the wire, make sure the visible sheath section is neat.
•
When stripping the insulation sleeve, do not damage the shielding layer, cable conductor, or
cable sleeves that do not require treatment.
•
It is strictly forbidden to touch the stripped cable conductors directly with bare hands.
•
The stripped cable conductor must be processed in time to prevent oxidation of the conductor
surface.
