In the description of the utility model, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0022] In the description of the utility model, it should be explained that, unless otherwise explicitly specified and limited, the terms "installation", "connection", "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrally connected, it can be mechanical connection, or electrical connection, it can be directly connected, or indirectly connected through intermediate medium, it can be the communication inside two elements. For ordinary skilled persons in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0023] The technical scheme in the embodiments of the utility model will be clearly and completely described below in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary skilled persons in the art without creative labor belong to the scope of protection of the utility model.

[0024] Please refer to Figures 1-4 A kind of insulating paper sleeve for communication, including outer sleeve 1 and inner sleeve 2, outer sleeve 1 and inner sleeve 2 are made of elastic insulating rubber material, two inner sleeves 2 are symmetrically arranged about the middle section of outer sleeve 1, inner sleeve 2 is movably installed in outer sleeve 1, and two outer sleeves 1 are distributed at the two ends of inner sleeve 2, so that when inner sleeve 2 is stretched and contracted relative to outer sleeve 1, the use length of the entire insulating paper sleeve can be adjusted, a through strip-shaped opening is provided on the periphery of outer sleeve 1 along the axial direction, an opening is provided on the periphery of inner sleeve 2 along the axial direction, which is aligned with the opening of outer sleeve 1, so that outer sleeve 1 and inner sleeve 2 can be opened along the axial direction, so as to be directly sleeved on the outer side of electric wire and cable without penetrating from the end, one side of the opening on outer sleeve 1 is provided with a buckle strip 11, and the other side of the opening is provided with a sleeve strip 12, the sleeve strip 12 and the buckle strip 11 are matched and buckled, the buckle strip 11 can be clamped in the sleeve strip 12, so as to lock outer sleeve 1, and outer sleeve 1 can be wrapped around inner sleeve 2.

[0025] In order to improve the strength of the insulating sleeve, the outer wall of the outer sleeve 1 is provided with a plurality of reinforcing ribs 13 which are parallel to the axial direction of the outer sleeve 1, and the reinforcing ribs 13 are evenly distributed along the circumference of the outer sleeve 1. The reinforcing ribs 13 are protruded relative to the outer wall of the outer sleeve 1, and in use, the reinforcing ribs 13 are first contacted with external objects, thereby reducing the frictional damage of the outer sleeve 1 during use.

[0026] Further, the reinforcing ribs 13 are internally provided with cavities 131 which are through at both ends, and when the cavities 131 are compressed, the reinforcing ribs 13 have a certain buffering effect, further improving the protection of the outer sleeve 1.

[0027] The end ring 21 is provided at the end of the inner sleeve 2 which extends out of the outer sleeve 1, and the outer diameter of the end ring 21 is consistent with the outer diameter of the outer sleeve 1, so as to be aligned with the outer sleeve 1. A plurality of limiting strips 22 corresponding to the reinforcing ribs 13 are arranged on the outer circumferential side wall of the end ring 21. The limiting strips 22 are made of hard rubber, which has higher stability and is not easy to bend, so as to be conveniently slid through into the cavities 131, thereby limiting the inner sleeve 2, preventing the inner sleeve 2 from rotating and deviating too much in the circumferential direction in the outer sleeve 1. At the same time, the outer diameter of the limiting strips 22 is smaller than the inner diameter of the cavities 131, so that the limiting strips 22 can move in the cavities 131.

[0028] The inner segment of the outer sleeve 1 is provided with a boss 14, and the thickness of the boss 14 is equal to the thickness of the inner sleeve 2, so that the boss 14 overlaps with the inner ring of the inner sleeve 2, thereby being kept on the same plane. The inner circumferential side wall of the boss 14 and the inner sleeve 2 is connected with the insulating paper layer 3, which is beneficial to improve the insulation effect.

[0029] In order to facilitate the expansion and contraction adjustment between the inner sleeve 2 and the outer sleeve 1 to be more stable, a plurality of convex rings 15 are arranged on the inner wall of the outer sleeve 1 which is located on both sides of the boss 14 along the axial direction, and a plurality of ring grooves 23 corresponding to the convex rings 15 are arranged on the outer wall of the inner sleeve 2. By using the convex rings 15 to be clamped into the ring grooves 23 in different positions, the expansion and contraction lengths of different inner sleeves 2 and outer sleeves 1 are limited. When adjustment is needed, the inner sleeve 2 can be deformed and bent due to the support of the flexible rubber, so as to facilitate the separation of the ring grooves 23 of the inner sleeve 2 and the convex rings 15.

[0030] It is apparent for a person skilled in the art that the present application is not limited to the details of the above-described exemplary embodiments, but that it can be implemented in other concrete forms without departing from the spirit or the essential characteristics of the present application.
