Abstract
The utility model relates to the anti-displacement structure of a kind of heating wire metallic sheath, comprise the fixed cover that heating wire, metallic sheath and insulating material are made, described heating wire is made up of inner core and the insulating case be coated on outside described inner core, the fixed cover end that described metallic sheath is sleeved on adjacent two heating wires is provided with circular packing ring, and the diameter of the packing ring of described circle is greater than the diameter 10mm-2mm of described fixed cover.Arranging of packing ring can ensure on the contact of inner core, described fixed cover is coated on the outside of described metallic sheath, it is characterized in that: pull insulating case in the process of heating wire described in close on described insulating case and can not be subject to axial force, thus effectively avoid the metallic sheath be connected with fixed cover to be shifted, eliminate safe hidden trouble.
Description
Technical field
The utility model belongs to field of cable technology, particularly relates to the anti-displacement structure of a kind of heating wire metallic sheath.
Background technology
Heating cable makes the construction of cable, take electric power as the energy, utilizes alloy resistance wire to carry out heating power, reach the effect of heating or insulation.Usually have singly lead and two lead point, be called heating cable.Heating cable is made up of inner core and the insulating barrier having coated inner core.At present, heating cable is due to the restriction of materials and structures, and cause the use length of heating cable to be restricted, the inner core of heating cable links together by root mainly through the mode of serial connection by people, and there is tie point between adjacent two heating cables, this tie point is wound around by inner core and forms, in order to carry out energising protection to tie point, usually metallic sheath is set at tie point place, with metallic sheath, tie point is wrapped up, on the one hand for the protection of tie point, metallic sheath has conducting function on the other hand, can promote that the energising of tie point is smooth and easy, fix the chuck that plastics are made afterwards again outside metallic sheath.But, be easy to the displacement of the metallic sheath causing fixed cover inside when cable uses and pulls, make metallic sheath can not cover tie point completely, cause tie point to be revealed, occur leaky, there is great potential safety hazard.
Summary of the invention
The utility model is the technical problem solving in known technology the metallic sheath that exists and be easily shifted and provide a kind of anti-displacement structure of heating wire metallic sheath that metallic sheath can be prevented to be shifted.
The technical scheme that the utility model is taked for the technical problem existed in solution known technology is: the anti-displacement structure of a kind of heating wire metallic sheath, comprise heating wire, the fixed cover that metallic sheath and insulating material are made, described heating wire is made up of inner core and the insulating case be coated on outside described inner core, described metallic sheath is sleeved on the contact of the inner core of adjacent two heating wires, described fixed cover is coated on the outside of described metallic sheath, it is characterized in that: described insulating case is provided with circular packing ring near described fixed cover end, the diameter of the packing ring of described circle is greater than the diameter 10mm-2mm of described fixed cover.
The utility model can also adopt following technical measures:
The diameter of the packing ring of described circle is greater than the diameter 10mm of described fixed cover.
The advantage that the utility model has and good effect are: because the utility model adopts as above technical scheme, namely on heating wire, packing ring is installed, arranging of packing ring can ensure that insulating case can not be subject to axial force in the process pullling heating wire, thus effectively avoid the metallic sheath be connected with fixed cover to be shifted, eliminate safe hidden trouble.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, metallic sheath; 2, fixed cover; 3, inner core; 4, insulating case; 5, packing ring.
Embodiment
For summary of the invention of the present utility model, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1, the anti-displacement structure of a kind of heating wire metallic sheath, comprises the fixed cover 2 that heating wire, metallic sheath 1 and insulating material are made.Heating wire is made up of inner core 3 and the insulating case 4 be coated on outside described inner core 3.Metallic sheath 1 is wrapped in the contact place of the inner core 3 of two adjacent heating wires.Fixed cover 2 is sleeved on the outside of described metallic sheath 1 and clad metal overlaps 1, to play the protective effect to metallic sheath 1.
Insulating case 4 is provided with circular packing ring 5 near fixed cover 2 end, and the diameter of the packing ring 5 of described circle is greater than the diameter 10mm-2mm of described fixed cover 2.Arranging of packing ring 5 can ensure that insulating case can not be subject to axial force in the process pullling heating wire, thus effectively avoids the metallic sheath 1 be connected with fixed cover 2 to be shifted, and eliminates safe hidden trouble.In the present embodiment, the diameter of circular packing ring 5 is greater than the diameter 10mm of described fixed cover.
