Abstract
The utility model provides a kind of cable for switch board, including conductor, and the conductor is coated with flexible insulating layer, the flexible insulating layer is coated with elastic body jacket layer, the cable of the utility model solves copper conductor problem of oxidation existing for rubber covered wire, improves cable service life.
Description
Technical field
The utility model is related to field of cables, and in particular to arrive a kind of cable for switch board.
Background technology
The requirement for the electric wire that current all kinds of switch boards are used for substantially has following two other than fire-protection standard
Point：
(1) because switch board inner space is limited, so the electric wire outer diameter used wants small；
(2) because of the requirement of threading, the pliability of electric wire will be got well.So what the cable in current switch board much used
It is rubber covered wire.But rubber plays the role of catalytic degradation to copper conductor, so using for a long time even in a short time, in electric wire
Copper conductor surface will change colour or even blackening.As shown in Figure 1 is exactly a kind of currently used switch board connecting line, specially
It is made of conductor 1 and rubber-covered 2.
Utility model content
In order to solve the above technical problems, the utility model provides a kind of cable for switch board, the utility model
Cable solves the problems, such as rubber covered wire copper conductor oxidation stain.
The utility model provides a kind of cable for switch board, including conductor, and the conductor is coated with flexible exhausted
Edge layer, the flexible insulating layer are coated with elastic body jacket layer.
Above-mentioned cable, wherein the flexible insulating layer is flexible PVC insulating layer, and the elastic body jacket layer is elasticity
Polystyrene restrictive coating.
Above-mentioned cable, wherein the thickness of the flexible PVC insulating layer is 0.4~0.8mm.
Above-mentioned cable, wherein the conductor is twisted by wire spiral of the 1-1000 roots through drawing.
Above-mentioned cable, wherein the base material of the wire is the soft copper silk or Cu-base composites of annealing.
Above-mentioned cable, wherein the thickness of the elastic body jacket layer is 0.5~3mm.
The utility model has the following advantages：
1, the cable of the utility model solves copper conductor problem of oxidation existing for rubber covered wire, improves cable and uses the longevity
Life.
Description of the drawings
Upon reading the detailed description of non-limiting embodiments with reference to the following drawings, the utility model and its spy
Sign, shape and advantage will become more apparent upon.Identical label indicates identical part in whole attached drawings.Not deliberately according to
Ratio draws attached drawing, it is preferred that emphasis is shows the purport of the utility model.
Fig. 1 is a kind of currently used switch board connecting line.
Fig. 2 is a kind of structural schematic diagram of cable for switch board provided by the utility model.
Specific implementation mode
In the following description, a large amount of concrete details are given more thoroughly to manage in order to provide to the utility model
Solution.It is, however, obvious to a person skilled in the art that the utility model may not need it is one or more of these thin
It saves and is carried out.In other examples, in order to avoid obscuring with the utility model, for more well known in the art
Technical characteristic is not described.
In order to thoroughly understand the utility model, detailed step and detailed structure will be proposed in following description,
To illustrate the technical solution of the utility model.The preferred embodiment of the utility model is described in detail as follows, however in addition to these
Detailed description is outer, and the utility model can also have other embodiment.
Shown in reference picture 1, Fig. 2, the utility model provides a kind of cable for switch board, including conductor 1, conductor 1
It is coated with flexible insulating layer 3, flexible insulating layer 3 is coated with elastic body jacket layer 4, and the utility model in conventional by leading
One layer of flexible insulating layer 3 is increased between body 1 and elastic body jacket layer 4, solves copper conductor problem of oxidation existing for rubber covered wire,
Improve cable service life.
In the utility model one in preferred but unrestricted embodiment, flexible insulating layer 3 is flexible PVC insulating layer, can be with
Play the role of insulation, elastic body jacket layer 4 is elastic polystyrene restrictive coating.
In the utility model one in preferred but unrestricted embodiment, the thickness of flexible PVC insulating layer is 0.4~0.8mm,
Preferably 0.6mm is being played while reaching insulation performance, it may have preferable flexible.
In the utility model one in preferred but unrestricted embodiment, conductor is by wire spiral of the 1-1000 roots through drawing
It is twisted.
In the utility model one in preferred but unrestricted embodiment, the base material of wire is the soft copper silk or copper-based of annealing
Composite material.
In the utility model one in preferred but unrestricted embodiment, the thickness of elastic body jacket layer is 0.5~3mm, excellent
It is selected as 1.5mm.
The utility model is expanded on further in a specific embodiment presented below
Embodiment 1, a kind of cable for switch board, including conductor 1, conductor 1 are coated with flexible insulating layer 3, flexible
Insulating layer 3 is coated with elastic body jacket layer 4, and flexible insulating layer 3 is flexible PVC insulating layer, can play the role of insulation, bullet
Property body restrictive coating 4 be elastic polystyrene restrictive coating, the thickness of flexible PVC insulating layer is 0.6mm, is reaching insulating properties playing
While energy, it may have preferable flexible, conductor is twisted by wire spiral of the 1-1000 roots through drawing, the base of wire
Material is the soft copper silk or Cu-base composites of annealing, and the thickness of elastic body jacket layer is 1.5mm.
The cable for switch board of embodiment 1, solves copper conductor problem of oxidation existing for rubber covered wire, improves cable
Service life, service life can be increased to 20 years or more by original 5 years.
The preferred embodiment of the utility model is described above.It is to be appreciated that the utility model not office
It is limited to above-mentioned particular implementation, wherein the equipment and structure be not described in detail to the greatest extent are construed as with the common side in this field
Formula is practiced；Any technical person familiar with the field all may be used in the case where not departing from technical solutions of the utility model ambit
Many possible changes and modifications are made to technical solutions of the utility model using the methods and technical content of the disclosure above, or are repaiied
