It is to solve existing technical problem in the existing cable mounting technique that the utility model also has a purpose; A kind of problem that the pyrocondensation product can not be installed in the place of some specific (special) requirements that overcome is provided, has installed more simply, a kind of cold-contraction type cable intermediate joint more easily.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals:
A kind of cold-contraction type cable intermediate joint is characterized in that, comprises that one and half lead shielded-plate tube and are arranged on the conductive component of partly leading in the shielded-plate tube, and said conductive component two ends also are provided with stress cone.
At above-mentioned a kind of cold-contraction type cable intermediate joint, conductive component comprises a protective sleeve and is arranged on the conductive core in the protective sleeve that said protective sleeve middle part outer wall is along semiconductive pipe layer circumferentially also is set.
At above-mentioned a kind of cold-contraction type cable intermediate joint, said stress cone is set in above-mentioned protective sleeve two ends respectively; The vertical setting of this stress cone one end is close to the protective sleeve outer wall, and the other end is an arc and gradually away from the protective sleeve outer wall.
At above-mentioned a kind of cold-contraction type cable intermediate joint, described protective sleeve outer wall and partly lead and also be filled with insulating barrier between the shielded-plate tube inwall.
At above-mentioned a kind of cold-contraction type cable intermediate joint, the said shielded-plate tube outer wall of partly leading also is provided with at least two prompting bulge loops, one of them prompting bulge loop plane and the parallel and coplane of above-mentioned semiconductive pipe layer one end end face; Another prompting bulge loop plane and the parallel and coplane of above-mentioned semiconductive pipe layer other end end face.
As another kind of technical scheme; At above-mentioned a kind of cold-contraction type cable intermediate joint; The said shielded-plate tube outer wall of partly leading also is provided with three prompting bulge loops; Be respectively the first prompting bulge loop, the second prompting bulge loop and the 3rd prompting bulge loop, the first prompting bulge loop plane and the parallel and coplane of above-mentioned semiconductive pipe layer one end end face; The second prompting bulge loop plane and the parallel and coplane of above-mentioned semiconductive pipe layer other end end face, the 3rd prompting bulge loop are arranged between the first prompting bulge loop and the second prompting bulge loop.
At above-mentioned a kind of cold-contraction type cable intermediate joint, said the 3rd prompting bulge loop and the first prompting bulge loop and and the second prompting bulge loop equidistance setting.
Therefore, the utlity model has following advantage: 1. reasonable in design, simple in structure and complete practicality; 2. without burning things which may cause a fire disaster and special tool(s), do not have the trouble of being inserted in gradually yet, only need extract the core rope gently, will rely on the elastical retraction of self, thereby tightly card is attached on the cable, has overcome the sandwich construction problem of pyrocondensation product, and the complexity of installing; 3. overcome the problem that the pyrocondensation product can not be installed in the place of some specific (special) requirements, installed simpler, more convenient.
