Utility model content
In view of this, the purpose of this utility model is to provide a kind of novel cold-shrinking intermediate joint of good water-proof effect, ensures the class of insulation at cable joint place, operation that can be safe and reliable.
The utility model adopts following scheme to realize: a kind of novel cold-shrinking intermediate joint, comprise the silicone rubber sleeve being sheathed on two cable joint ends, described silicone rubber sleeve two ends are pyramidal structure, two cables are arranged with horn-like gland respectively, the peviform opening of described gland in towards silicone rubber sleeve side and with the silicone rubber sleeve tapered end compression fit of corresponding end; The peviform peristome of described gland is arranged at intervals with slot; Described silicone rubber sleeve outer race is provided with sleeve; Described gland is also arranged with the adapter sleeve be connected with sleeve corresponding end, described adapter sleeve comprises and the tapered ring part of the peviform peristome periphery compression fit of gland and the ring bodies that is connected with sleeve corresponding end.
Further, described sleeve ends is provided with internal thread, and the internal thread that the ring bodies end of described adapter sleeve is provided with sleeve corresponding end spins the external screw thread coordinated.
Further, on described gland in order to wear cable endoporus in offer cannelure, be embedded with water-swellable cushion rubber in described cannelure.
Further, described sleeve peripheral part and adapter sleeve ring bodies peripheral part are equipped with anti-skidding lines.
Compared with prior art, the utility model has following beneficial effect: this novel cold-shrinking intermediate joint good airproof performance, good water-proof effect, ensure the class of insulation at cable joint place, operation that can be safe and reliable, mechanical strength is high simultaneously, can prevent mechanical damage and corrosion.

Embodiment
For making the purpose of this utility model, technical scheme and advantage clearly understand, below by specific embodiment and relevant drawings, the utility model will be described in further detail.
As shown in Figure 1 and 2, a kind of novel cold-shrinking intermediate joint, comprise the silicone rubber sleeve 2 being sheathed on two cable 1 tip sides, described silicone rubber sleeve 2 two ends are pyramidal structure, two cables 1 are arranged with horn-like gland 3 respectively, the peviform peristome 4 of described gland 3 be positioned at towards silicone rubber sleeve 2 side and with the silicone rubber sleeve 2 tapered end compression fit of corresponding end; The peviform peristome 4 of described gland 3 is arranged at intervals with slot 5, described slot runs through the inside and outside sidewall of peviform peristome diametrically, run through the open end of peviform peristome in the axial direction, wherein slot 5 can make the easier compacted gathering of the peviform peristome of gland; Described silicone rubber sleeve 2 outer race is provided with sleeve 6; Described gland 3 is also arranged with the adapter sleeve 7 be connected with sleeve 6 corresponding end, described adapter sleeve 7 comprises and the tapered ring part 8 of the peviform peristome 4 periphery compression fit of gland 3 and the ring bodies 9 that is connected with sleeve 6 corresponding end; Adopt symmetrical structure, not only facilitate adapter sleeve to fix, stress equalization, there will not be silicone rubber sleeve 2 be out of shape and affect sealing simultaneously, and sleeve 6 and adapter sleeve 7 can also prevent silicone rubber sleeve 2 to be subject to mechanical damage and corrosion simultaneously.
In the present embodiment, described sleeve 6 end is provided with internal thread, the internal thread that ring bodies 9 end of described adapter sleeve 7 is provided with sleeve 6 corresponding end spins the external screw thread coordinated, when shown adapter sleeve 7 screws with sleeve 6 end, adapter sleeve 7 is drawn close to silicone rubber sleeve 2 middle shrinkage, and then the tapered ring part 8 of adapter sleeve 7 extrudes gland 3, the opening of gland 3 peviform peristome 4 is drawn in, and then make the tapered end of silicone rubber sleeve 2 be extruded contraction, close contact is kept with the peripheral part of cable 1, ensure permanent radial load, guarantee blind-mate between silicone rubber sleeve 2 and cable, there is good sealing, make circuit unimpeded, and ensure the class of insulation at cable joint place, operation that can be safe and reliable.
In the present embodiment, on described gland 3 in order to wear cable 1 endoporus 10 in offer cannelure 11, be embedded with water-swellable cushion rubber 12 in described cannelure 11, when by rainwater, water-swellable cushion rubber 12 water-swellable, has better waterproof effect.
In the present embodiment, conveniently sleeve 6 and adapter sleeve 7 rotate each other, and described sleeve 6 peripheral part and adapter sleeve 7 ring bodies 9 peripheral part are equipped with anti-skidding lines.
Above-listed preferred embodiment; the purpose of this utility model, technical scheme and advantage are further described; be understood that; the foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
