Description

Technical field:

[0001] The invention belongs to the technical field of cable installation, and in particular relates to a novel cable sleeve installation mechanism. Background technology:

[0002] The water pump cable consists of an insulation layer and multiple core wires nestled within it. For electrical connection, a section of the cable is typically stripped of insulation, exposing the core wires. To secure the cable, an outer sheath is typically placed over the insulated cable, while an inner sheath is placed over the uninsulated cable. The inner sheath has multiple through-holes for the core wires to pass through, and the ends of the inner sheath are inserted into the outer sheath.

[0003] When manually installing a sleeve, the outer sleeve is usually first placed over the cable, followed by the inner sleeve. The inner sleeve is then pushed down firmly until it reaches the junction of the insulated and uninsulated sections of the cable. The inner sleeve is then held and pushed upward firmly until the upper end of the outer sleeve is placed over the inner sleeve, completing the connection. This is quite laborious. Furthermore, because the core wires at the junction of the insulated and uninsulated sections of the cable are typically wrapped with insulating tape, the outer diameter of the tape-covered core wire is larger than that of the untaped core wire. Therefore, moving the inner sleeve over the tape-covered core wire is more laborious.

[0004] The disadvantages of the existing installation method are that the installation is laborious, slow, labor-intensive, and there is a risk of the sleeve scratching people when applying force, which is low in safety. Summary of the invention:
