Description
Technical field
The utility model belongs to fixed wiring technical field of electric wires and cables, and in particular to it is a kind of be easily installed it is tearable
Type sheath flat wire.
Background technique
Flat cotton covered wire currently on the market is usually that insulated wire cores are arranged in parallel, and electric wire oversheath squeezes out one by standard requirements
The smooth sheath material of layer, structure are in platypelloid type, and oversheath thickness is uniform.Sheath allows to fill up the gap between core and constitutes
Filling, in the production of traditional cable, sheath production is mostly produced using fashion of extrusion, and jacket surface is smooth consistent, and squeezes
The sheath that mode produces is difficult to remove in construction, it is necessary to thus very big to causing when installing wiring by professional tool
Inconvenience cause very big difficulty to wire stripping especially when there is no tool, and peel insulation off with metal knife, make to lead
Body and insulated separation, metal knife is easy to a conductor in the process or insulation harm causes to scrap, cause labor intensity it is high,
Efficiency is lower.In addition, tearing not in place, stability appraisal often being wanted, so very unrestrained even if tearing and being easy tear fracture after cutting off sheath again
It is time-consuming；Patent No. 2015203446090 and a kind of entitled " tearable flat type electricity of polyvinyl chloride-insulated polyvinyl chloride
In the patent document of cable ", due to tear rope of the tearable PVC outer jacket internal protrusion between two neighboring PVC insulating layer
Place, when drawing tear rope to tear tearable PVC outer jacket outside, tearable PVC outer jacket internal protrusion is to tear rope
Resistance is larger, since tear rope is thinner, easily causes to strangle trace to operator's finger, in view of the above-mentioned problems, it is necessary to improve.
Utility model content
The technical problem solved by the utility model is:to provide a kind of tearable type sheath flat wires being easily installed, by phase
Adjacent insulated wire cores side, which is provided with, easily tears the tear rope of pad, can effectively avoid restrictive coating and extrudes the protrusion that is formed after molding to tearing
The influence of rope is split, while guaranteeing that restrictive coating thinnest point thickness complies with the national standard requirements, reduces outer drawing tear rope tearing shield
Pulling force when jacket layer improves restrictive coating charge stripping efficiency, brings great convenience to mounting and installation.
The technical solution adopted in the utility model: the tearable type sheath flat wire being easily installed, including conductor, insulating layer,
Tear rope and restrictive coating, form insulated wire cores after the outer extruded insulation layer of the conductor, the adjacent insulated wire cores side be equipped with
It is extruded outside insulated wire cores and tear rope outside the parallel tear rope of insulated wire cores and restrictive coating, restrictive coating outer wall two sides are equal
Be formed with separation trough and tear rope be corresponding with the separation groove location of restrictive coating side, the tear rope bottom be fixed with easily tear pad and easily
The separation trough for tearing V-arrangement angle towards the restrictive coating outer wall side of pad lower end is arranged.
Wherein, the tear rope is the rope of high-tensile, and the pad upper surface of easily tearing is arcwall face and easily tears on pad
The separation trough that the arcwall face at end is bonded V-arrangement angle towards restrictive coating outer wall side connected and that easily tear pad lower end with tear rope bottom is set
It sets.
Further, the conductor is simple solid copper conductor or simple solid aluminium conductor.
Further, the conductor is more twisted copper conductors or more stranded aluminum conductors.
Further, the insulated wire cores are no less than two.
The utility model compared with prior art the advantages of:
1, the technical program easily tears the tear rope of pad by being provided in adjacent insulated wire cores side, can effectively avoid shield
Jacket layer extrudes influence of the protrusion formed after molding to tear rope, removes convenient for restrictive coating；
2, the technical program reduces outer tearing while guaranteeing that restrictive coating thinnest point thickness complies with the national standard requirements
Pulling force when rope tearing restrictive coating is split, restrictive coating charge stripping efficiency is improved, brings great convenience to mounting and installation；
3, the technical program structure is simple, and restrictive coating removing is convenient, and the stripping of restrictive coating can be only completed with the power of 10-30N
From solving the problems, such as that the restrictive coating in sheath flat wire is not easily stripped.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model.
Specific embodiment
1 an embodiment of the present invention is described with reference to the accompanying drawing.
The tearable type sheath flat wire being easily installed, including conductor 1, insulating layer 2, tear rope 3 and restrictive coating 4, it is described to lead
Insulated wire cores are formed after the outer extruded insulation layer 2 of body 1, the adjacent insulated wire cores side is equipped with the tear rope parallel with insulated wire cores
3 and restrictive coating 4 outside extrude outside insulated wire cores and tear rope 3, the 4 outer wall two sides of restrictive coating are formed with separation trough 6 and tear
It is corresponding with 6 position of separation trough of 4 side of restrictive coating to split rope 3,3 bottom of tear rope, which is fixed with, easily tears pad 5 and easily tear 5 lower ends of pad
V-arrangement angle towards 4 outer wall side of restrictive coating separation trough 6 be arranged；Specifically, the tear rope 3 is the rope of high-tensile,
5 upper surfaces of pad of easily tearing are arcwall face and easily tear the arcwall faces of 5 upper ends of pad be bonded with 3 bottom of tear rope connected and easy tear pad 5
The separation trough 6 of the V-arrangement angle of lower end towards 4 outer wall side of restrictive coating is arranged；The conductor 1 is simple solid copper conductor or single reality
Heart aluminium conductor；Specifically, the conductor be more twisted copper conductors or more stranded aluminum conductors specifically, the insulated wire cores not
Less than two.
The structure for the tearable type sheath flat wire that the technical program autonomous Design is easily installed, in adjacent insulated wire cores one
Side increases by one with high-tensile and with the tear rope 3 for easily tearing pad 5, is easy to the tearing of restrictive coating 4 when needing, using primary
Coextrusion process extrudes tear line 3 outside insulated wire cores with restrictive coating 4 outside, and insulating layer 2 uses the polyvinyl chloride of standard requirements
Insulating materials, restrictive coating 4 are extruded in outside insulating layer 2 and tear rope 3 using the PVC sheath material of standard requirements, separation trough
6 use an improved extrusion molding of jacket extrusion mould.
The technical program easily tears the tear rope 3 of pad 5 by being provided in adjacent insulated wire cores side, can effectively avoid shield
Jacket layer 4 extrudes influence of the protrusion formed after molding to tear rope 3, removes convenient for restrictive coating 4, is guaranteeing 4 thinnest point of restrictive coating
While thickness complies with the national standard requirements, pulling force when outer drawing tear rope 3 tears restrictive coating 4 is reduced, only with 10-30N's
Power can complete the removing of restrictive coating 4, solve the problems, such as that the restrictive coating 4 in sheath flat wire is not easily stripped, improve shield
4 charge stripping efficiency of jacket layer, brings great convenience to mounting and installation, and structure is simple, and restrictive coating removing is convenient.
