[0024] Reference Figs. 1-3 An embodiment of the utility model shown is:

[0025] A kind of wire insulation sheath, including insulating sleeve 1, the both ends of the insulating sleeve 1 are equipped with sleeve compression member, the outer wall of the insulating sleeve is equipped with the positioning ring 2 of adapting the sleeve compression member, the sleeve compression member includes socket cover 3, elastic member 4, sheath clamp 5, plug cover 6 arranged in sequence, the socket cover 3 is threadedly connected with the plug cover 6 and is set in the insulating sleeve 1 outside, the end of the socket cover 3 away from the plug cover 6 is equipped with the clamping ring 7 of adapting the elastic member 4, the elastic member 4 is divided and arranged at the both sides of the positioning ring 2 with the sheath clamp 5, the side of the sheath clamp 5 away from the positioning ring 2 is equipped with a plurality of first axial clamping pieces 8, the outer diameter size of the first axial clamping piece 8 gradually increases, the plug cover 6 is equipped with the limiting groove 9 of adapting the first axial clamping piece 8.

[0026] Specifically, the insulating sleeve 1 is made of rubber material, the socket cover 3, the sheath clamp 5 and the plug cover 6 of the sleeve compression member are made of plastic material, and the elastic member 4 can be an elastic gasket or a spring.Because the overall size of the sheath is relatively small, the elastic gasket is used in the embodiment.

[0027] The positioning ring 2 is used to stabilize the position of the sleeve compression member and avoid its movement on the insulating sleeve 1. In use, the socket sleeve 3 and the elastic member 4 are previously arranged at the middle part of the insulating sleeve 1, i.e. between the two positioning rings 2, and the sheath clamp 5 and the plug sleeve 6 are arranged on the to-be-connected conductor. Then, the insulating sleeve 1 is arranged on any to-be-connected conductor, and after the core of the conductor is connected, the insulating sleeve 1 is moved to completely cover the conductor joint. Then, the sheath clamp 5 and the plug sleeve 6 are inserted and matched, and the sheath clamp 5 is abutted against the positioning ring 2. The socket sleeve 3 and the plug sleeve 6 are moved and screwed, and in the screwing process, the first axial clamping piece 8 is gradually extruded, and in the process of reducing the inner diameter size, the insulating sleeve 1 is gradually tightly fitted with the rubber layer outside the conductor, so that the fixation and sealing of the insulating sleeve 1 are realized, and the reliable use of the conductor in the complex outdoor environment for a long time is effectively ensured.

[0028] After assembly, the elastic member 4 is tightly arranged on the two sides of the positioning ring 2 and the sheath clamp 5, so as to stabilize the position of the sleeve compression member and avoid its movement on the insulating sleeve 1. The distance from the positioning ring 2 to the end of the insulating sleeve 1 should have a redundant length for installing the sleeve compression member.

[0029] In order to ensure the strength of the positioning ring 2, the positioning ring 2 and the insulating sleeve 1 can be integrally formed.

[0030] In order to improve the sealing performance, a plurality of second axial clamping pieces 10 are arranged on the plug sleeve 6, the outer wall of the second axial clamping piece 10 is provided with a first threaded portion 101, and the second axial clamping pieces 10 between adjacent ones form the limiting groove 9.

[0031] The limiting groove 9 is used to limit the movement of the sheath clamp 5. When the first axial clamping piece 8 extrudes the insulating sleeve 1, other parts of the insulating sleeve 1 in the circumferential direction will expand outward. The first threaded portion 101 is arranged on the second axial clamping piece 10 by adopting the split design. When the socket sleeve 3 and the plug sleeve 6 are screwed, the second axial clamping piece 10 is extruded inward and tightly fitted with the expanded part, so as to improve the sealing performance.

[0032] Since the inner diameter of the second axial clamping piece 10 extruded by the first axial clamping piece 8 will be reduced, the insulating sleeve 1 may be damaged during rotation. In actual installation, the plug sleeve 6 should be kept stable, and only the socket sleeve 3 is rotated.

[0033] In order to ensure the movement space of the first axial clamping piece 8, the depth of the limiting groove is greater than the length of the first axial clamping piece 8. Meanwhile, in order to facilitate the disengagement of the socket sleeve 3 and the plug sleeve 6, the end of the first axial clamping piece 8 is provided with an inclined surface to facilitate the exit of the socket sleeve 3.

[0034] The inner side wall of the first axial clamping piece 8 is provided with a clamping tooth 11 matched with the insulating sleeve 1. After the socket sleeve 3 and the plug sleeve 6 are screwed tightly, the clamping tooth 11 can more reliably clamp the insulating sleeve 1 on the wire, avoid the insulating sleeve 1 from moving on the wire, and ensure the reliability of the insulating sleeve 1 during long time use.

[0035] The shaft hole of the socket sleeve 3 is provided with a second threaded part 301 matched with the first threaded part 101, and the second threaded part 301 has a gap to the end of the socket sleeve 3.

[0036] Since the wire connection part can have a protruding core, in order to facilitate the socket sleeve 3 to pass through the protruding part, the inner diameter of the clamping ring 7 is greater than the outer diameter of the insulating sleeve 1.

[0037] Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement to part of the technical features, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
