Abstract
The utility model discloses a waterproof type cable of modified, including heart yearn, insulating layer and protective layer, its characterized in that: the protective layer includes and external coating and interior protective layer is equipped with a plurality of connecting pieces between external coating and the interior protective layer, and external coating's cross -section is the regular polygon structure, and the cross -section of interior protective layer is the circular structure of inscribe in external coating, forms buffer space between interior protective layer and the external coating, is filled with moisture absorption filler etc. In the buffer space. The utility model relates to a novel, manufacturing convenience, the sound construction, the performance of preventing breaking is strong, and water -proof effects is good, and application scope is wide, and long service life can effectively reduce maintenance and maintenance cost etc..
Description
Technical field
This utility model relates to field of cable technology, particularly relates to the waterproof cable of the improvement of a kind of sound construction, easily manufactured, length in service life.
Background technology
Cable is applied widely in the modern life and commercial production, and including power cable, communication cable and various electric wires etc., in structure, the general insulating barrier peripheral with being arranged at wire by some wires, protective layer form, and water resistance is general.Along with the development of science and technology, cable is in actual applications, it is often necessary to is arranged in the various complex environments such as underground, reservoir, tunnel, therefore has higher requirement the water resistance of cable.Owing to the usage amount of cable is relatively big, in order to reduce manufacture and the construction maintenance cost of cable further, needs the structure of cable is made the design of more innovation, extend the service life of cable.
Utility model content
For above-mentioned technical problem, this utility model provides the waterproof cable of a kind of improvement, and it is novel in design, easily manufactured, sound construction, and the anti-performance that fractures is strong, good water-proof effect, and applied widely, service life is long, it is possible to effectively reduce maintenance and maintenance cost etc..
For achieving the above object, the technical scheme that this utility model is used is.
A kind of waterproof cable of improvement; including heart yearn, insulating barrier and protective layer; it is characterized in that: described protective layer includes external protection and inner protective layer; some connectors it are provided with between external protection and inner protective layer; the cross section of external protection is regular polygon structure; the cross section of inner protective layer is the circular configuration being inscribed within external protection; cushion space is formed between inner protective layer and outer Baoshan sheath; being filled with hygroscopic fillers in cushion space, described insulating barrier includes the first insulating barrier being socketed on outside heart yearn and the second insulating barrier being arranged on the inwall of inner protective layer.
Preferably; described hygroscopic fillers uses powdery or the super absorbent resin of lamellar; super absorbent resin is a kind of novel macromolecular material; it has water absorption and water-retaining property concurrently; can effectively prevent moisture from penetrating in protective layer; improve the water resistance of cable, and the filler of powdery or lamellar is filled conveniently, is conducive to saving production cost.
Preferably, the cross section of described external protection is regular pentagon or regular hexagon structure, and the outer wall at protective layer is non-circular structure, and tension, anti-deformation effect are more preferable.
Preferably, described external protection, inner protective layer and connector are the integrative-structure using identical material to make.
The double protection structures of the inner protective layer that this utility model uses cross section to be the external protection of regular polygon structure and inscribe circular configuration; and filling between has water suction and the super absorbent resin filler of water retention property concurrently or uses other hygroscopic material to substitute; strengthen structural integrity and the water resistance of cable; effectively extend the service life of cable; and heart yearn has also been made double insulation protection process; improve stability and the reliability of cable transmission signal, there is high application value.
In sum, owing to have employed technique scheme, this utility model has the following technical effect that this utility model is novel in design, easily manufactured, sound construction, the anti-performance that fractures is strong, good water-proof effect, applied widely, service life is long, it is possible to effectively reduce maintenance and maintenance cost etc..
Accompanying drawing explanation
Fig. 1 is the cross section structure figure of preferred embodiment of the present utility model.
Detailed description of the invention
Further illustrate this utility model below by the mode of embodiment, but the most therefore this utility model is limited among described scope of embodiments.
It is illustrated in figure 1 the cross section structure schematic diagram of the waterproof cable of a kind of improvement, including heart yearn 1, insulating barrier and protective layer, wherein, protective layer includes external protection 31 and inner protective layer 32, some connectors 33 it are provided with between external protection 31 and inner protective layer 32, the cross section of external protection 31 is regular polygon structure, the cross section of inner protective layer 32 is the circular configuration being inscribed within external protection 31, cushion space 4 is formed between inner protective layer 32 and external protection 31, hygroscopic fillers 5 it is filled with in cushion space 4, insulating barrier includes the first insulating barrier 21 being socketed on outside heart yearn 1 and the second insulating barrier 22 being arranged on the inwall of inner protective layer 32.
As it is shown in figure 1, in the present embodiment, the cross section of external protection 31 is regular pentagon structure.
As further improvement of this embodiment, hygroscopic fillers 5 uses the super absorbent resin of powdery or lamellar.
It it is the integrative-structure using identical material to make as the another improvement of the present embodiment, external protection 31, inner protective layer 32 and connector 33.
The foregoing describing detailed description of the invention of the present utility model, it will be appreciated by those of skill in the art that these are merely illustrative of, protection domain of the present utility model is defined by the appended claims.These embodiments, on the premise of without departing substantially from principle of the present utility model and essence, can be made various changes or modifications, but these changes and amendment each fall within protection domain of the present utility model by those skilled in the art.
