Abstract
The utility model relates to a cable sheathing pipe technical field especially relates to a cable conductor insulating sheath. This sheath body outer wall is provided with a plurality of protection pieces, and this protection piece is scalable, protection piece and sheath body coupling, simultaneously, this sheath body is inside to be provided with the subregion, it has the insulating layer to fill around the subregion spool, wherein uses insulating support to separate between the subregion. By arranging the telescopic protection block on the outer wall, the protection of the inner wire pipe in the sheath can be effectively increased, and the pressure resistance of the whole cable is further enhanced; simultaneously at the inside subregion that sets up of sheath body to use the insulating support to separate the subregion, further strengthened the protection to inside spool, fill the insulating layer around the spool simultaneously, separate the temperature that the wire produced in the use, effectively prevent that inside wire is because ageing, and reduce the life of cable conductor. The utility model provides high cable conductor anti extrusion ability, anti deformability and ageing resistance ability.
Description
Technical Field
The utility model relates to a cable sheathing pipe technical field especially relates to a cable conductor insulating sheath.
Background
Cables are typically rope-like cables made up of several or groups of at least two twisted conductors each, and are widely used for power, communication and related transmission applications. The existing urban power grid construction and transformation project, urban municipal transformation project, civil aviation airport project construction, industrial park project construction, traffic road and bridge project construction, community project construction and the like all require that power cables, communication cables and the like are buried and laid so as to relieve ground space pressure. The existing cable buried protective sleeve is not high in strength, is easy to break when encountering an excavation accident, and can break the cable protective sleeve in the installation process, so that the cable is damaged.
For example, in the document CN103595003A, the present invention discloses a large size buried communication cable sheath tube, including: the protective sleeve comprises a protective sleeve body and a plurality of reinforcing ribs arranged outside the protective sleeve body, wherein the plurality of reinforcing ribs are uniformly distributed on the outer circumference of the protective sleeve body, reinforcing plates are arranged inside the protective sleeve body, and the reinforcing ribs and the protective sleeve body are of an integral structure. Through the mode, the cable has the advantage of high strength, is not easy to break, and can reduce the probability of damage to the cable.
Disclosure of Invention
In conclusion, in order to improve the anti-extrusion capacity, the anti-deformation capacity and the anti-aging capacity of the cable, the cable insulation sheath is specially provided.
The utility model relates to a cable conductor insulating sheath, this sheath body outer wall are provided with a plurality of protection pieces, and this protection piece is scalable, protection piece and sheath body a body coupling, simultaneously, this sheath body is inside to be provided with the subregion, it has the insulating layer to fill around the spool in the subregion, uses insulating support to separate wherein between the subregion.
According to the arrangement, the telescopic protection block is arranged on the outer wall of the cable insulation sheath, so that the protection of the inner conduit of the sheath can be effectively increased, and the pressure resistance of the whole cable can be further enhanced; simultaneously at the inside subregion that sets up of sheath body to use the insulating support to separate the subregion, further strengthened the protection to inside spool, fill the insulating layer around the spool simultaneously, separate the temperature that the wire produced in the use, effectively prevent that inside wire is because ageing, and reduce the life of cable conductor.
The utility model discloses further set up, subregion quantity is 2 at least.
The utility model discloses further set up, be provided with the spring in the protection piece.
The utility model discloses further set up, spring quantity is 1 at least.
The utility model discloses further set up, the protection piece is the flexible piece.
The utility model discloses beneficial effect:
the utility model discloses an effectual crushing resistance who has strengthened the cable conductor makes the cable conductor whole not take place to warp simultaneously again, and sets up the subregion and pack the insulating layer in the subregion, prevents that intraductal electric wire from because the high emergence of temperature is ageing, has effectively improved the protection to the cable conductor and has increased the life of cable conductor.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by the ordinary skilled person in the art without creative work all belong to the protection scope of the present invention.
As shown in fig. 1, an embodiment of the present invention includes:
the utility model provides a cable conductor insulating sheath, this sheath body outer wall is provided with a plurality of protection pieces 3, and this protection piece 3 is scalable, protection piece 3 and sheath body coupling, simultaneously, this sheath body is inside to be provided with subregion 6, fills insulating layer 1 around interior spool 2 that places in subregion 6, wherein uses insulating support 5 to separate between subregion 6.
The utility model discloses in, the quantity of subregion 6 sets up to two or more than two at least.
The utility model discloses in, in protection piece 3, can set up spring 4, and the quantity of spring is 1 or more than 1 at least.
The utility model discloses in, protection piece 3 is the flexible piece.
In-service use, an insulating sheath of cable conductor, sheath body outer wall is provided with a plurality of retractable type protection piece 3, and this protection piece 3 optional flexible piece, do wherein set up spring 4, when the cable conductor contacts ground or other objects, the protection piece 3 of retractable type can reduce the extrusion of other objects to the cable conductor, thereby improve the protection to the cable conductor, simultaneously at the inside subregion 6 that sets up of sheath body, and use insulating support 5 to separate between each subregion 6, because insulating support 5's supporting role, the anti extrusion ability of further increase cable conductor, fill insulating layer 1 around inner wire pipe 2 again simultaneously, not only protect not taking place the extrusion between each wire, and can also carry out the separation to the heat that each wire during operation produced.
The above description is only exemplary of the present invention and should not be taken as limiting, and any modifications, equivalents, improvements and the like that are made within the spirit and principles of the present invention should be included in the scope of the present invention.
