Description

Technical fields:

[0001] This utility model belongs to the field of cable installation technology, and specifically refers to a new type of cable sheathing installation mechanism. Background technology:

[0002] The water pump cable consists of an insulation layer and multiple core wires housed within the insulation layer. For electrical connection, a section of the cable typically has its insulation layer removed, exposing the core wires. To secure the cable, an outer sheath is usually fitted over the insulated cable, and an inner sheath is fitted over the uninsulated cable. The inner sheath has multiple through holes for the core wires to pass through, and the end of the inner sheath is inserted into the outer sheath.

[0003] When manually installing cable sleeves, the process typically involves first placing the outer sleeve over the cable, then slipping on the inner sleeve, and finally pushing the inner sleeve downwards until it reaches the junction of the insulated and uninsulated sections of the cable. Then, the inner sleeve is grasped, and the outer sleeve is pushed upwards until its upper end is fitted over the inner sleeve, completing the connection. This process is quite laborious. Furthermore, because the core wires at the junction of the insulated and uninsulated sections are usually wrapped with insulating tape, the outer diameter of the core wire with insulating tape is larger than that of the core wire without tape. Therefore, moving the inner sleeve over the core wire with insulating tape is also quite difficult.

[0004] The shortcomings of the existing installation method are: the installation is relatively labor-intensive, the installation speed is slow, the labor intensity is high, and there is a risk of the fixed sleeve scratching people when force is applied, resulting in low safety.
