Description

A METHOD AND ASSEMBLY FOR READY ACCESS CABLE TERMINATION

TECHNICAL FIELD

The present invention relates to a method and assembly for conveniently terminating multiple electrical cables.

BACKGROUND

Any references to methods, apparatus or documents of the prior art are not to be taken as constituting any evidence or admission that they formed, or form part of, the common general knowledge in the art.

Situations may arise during the installation of an electrical cabinet, housing electronic equipment, where it is necessary to terminate numerous electrical cables within the cabinet. Such cables may be subterranean with their ends brought up out of the ground at the site on which the cabinet is to be installed.

For example, Figure 1 depicts an outdoor, EV car charging station 1. EV charging station 1 includes an AC switchboard 3 that distributes 3 phase AC power to an electrical cabinet 5 by means of cables 4. The electrical cabinet 5 in turn distributes DC power to each of charging stations 7a,..,7n by means of DC feed cables 8a,... ,8n. In addition to the power cables, data cables such as Local Area Network (LAN) ethernet cables may also interconnect the charging stations 7a,... , 7n, electrical cabinet 5 and AC switchboard 3.

The terminals within the cabinet on which the cables are to be terminated may be at different levels and different distances from the point at which the cables rise up from the ground. It may be a time consuming and demanding task to terminate the different cables at the various termination points within the electrical cabinet. For example, typically the ends of the cables need to be cut to the correct length for their particular termination point and tips of the cables must be stripped. Often crimp connectors must then be applied.

Furthermore, it may be that there is a time lag between when the underground cables are laid and when the electrical cabinet is brought to site so that the cable ends are exposed for some time.

It would be advantageous to address one or more of the above issues and/or to provide the consumer with a useful or commercial alternative.
