Fig. 3 is a schematic structural diagram of a tightening coil according to an embodiment of the present utility model.
In the figure: 1. a tension ring; 2. tightening the coil; 3. sticking a coating; 4. sticking a protective film; 5. a protective film tear strip; 6. a sheath; 7. and thickening the end.
Detailed Description
The technical scheme of the utility model is further described below with reference to the accompanying drawings and examples.
As shown in fig. 1-3, to improve the efficiency and safety of the cable nose insulation construction. The utility model provides a simple type low-voltage cable nose protective sleeve which comprises a sheath 6 with a conical structure, wherein semicircular mounting pipes are arranged on two sides of the edge of an opening end of the sheath 6, a tightening coil 2 is slidably mounted in each mounting pipe, the end part of each tightening coil 2 is positioned outside each mounting pipe, a tightening ring 1 is fixedly connected with the movable end of each tightening coil 2, and a bonding coating 3 is arranged on the inner side of the opening end of the sheath 6.
The construction method comprises the following construction steps: 1. placing the cable nose towards the sealed end of the insulating sheath 6 through the open end of the sheath 6, wherein the nose part is just placed at the sealed end of the sheath 6; 2. the tightening rings 1 positioned on two sides of the sheath 6 are hooked by fingers, the tightening rings 1 are pulled towards the outer side direction of the sheath 6, and the tightening rings 1 drive the tightening coils 2 to move, so that the two tightening coils 2 are stressed and tightened; 3. under the drive of tightening coil 2, sheath 6 open end shrink to with sheath 6 open end hoops on the cable, sheath 6 open end is through pasting coating 3 adhesion on the cable, accomplishes the insulating construction of cable nose promptly.
As a preferred embodiment of the utility model, the tightness of the connection of the sheath 6 to the cable is further improved. The length of the cinch coil 2 outside the sheath 6 is greater than half the circumference of the open end of the sheath 6. After the open end of the sheath 6 is adhered to the surface of the cable through the adhesive coating 3, the two ends of the tightening coil 2 are controlled to be knotted through the tightening ring 1, so that the tightness of the connection between the sheath 6 and the cable is improved.
