SUMMARY

[0004] In view of the deficiencies in the prior art, the utility model provides a PVC electrician sleeve for the purpose of improving the compression resistance of the PVC electrician sleeve.

[0005] To solve the above technical problems, the utility model provides the following technical scheme:

[0006] A PVC electrician sleeve, comprising a sleeve body, a plurality of support walls are arranged on the inner wall of the sleeve body, and a plurality of support ribs are arranged on the inner side of the support walls.

[0007] Preferably, the side of the support wall away from the sleeve body is a plane or a smooth curved surface protruding into the interior of the sleeve body.

[0008] Preferably, the support walls are arranged along the axial direction of the sleeve body, the plurality of support walls are equidistantly arranged along the circumferential direction on the inner wall of the sleeve body, and the adjacent two support walls are connected.

[0009] Preferably, the number of support walls is an odd number not less than seven.

[0010] Preferably, the support ribs are in the shape of a long strip and are arranged along the axial direction of the sleeve body.

[0011] Preferably, the support ribs are equidistantly arranged in the direction perpendicular to the axial direction of the sleeve body on the side of the support wall, and the height of the support rib and the distance between two adjacent support ribs are both less than 1mm.

[0012] Preferably, the sleeve body, the support wall and the support rib are integrated.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. By arranging the support wall on the inner wall of the sleeve body, the overall wall thickness of the sleeve body is increased, the structural strength and support effect are improved, the compression resistance and torsional strength are improved, the deformation under external force is not easy, the deformation is not easy to crack and break, and the insulation effect is ensured.

[0015] 2. By arranging the support rib on the side of the support wall, the contact area of the internal wire is reduced, the heat dissipation effect is improved, the resistance of the inserted wire is reduced, the wire insertion is facilitated, and the construction and later wire replacement are facilitated.
