Detailed description of the invention
Fig. 1 is the preformed integrally-built fragmentary cross-sectional view of top wiring of all insulation of the utility model.
In figure: 1, pushing up wiring, 2, metal core, 3, insulating layer.
Specific embodiment
The utility model is described in further details with reference to the accompanying drawings and examples.
The preformed top wiring of all insulation, as shown in Figure 1, top wiring 1 is helical form, for conducting wire to be fixed on insulator top
Portion.Pushing up wiring 1 includes metal core 2 and insulating layer 3, and metal core 2 is located at center, and insulating layer 3 is coated on the outer surface of metal core 2,
That is the side surface and end of metal core 2 are coated with insulating layer 3, and insulating layer 3 is made of plastics, and insulating layer 3 and metal core 2 are one
Forming structure, insulating layer 3 and the integrally manufactured molding of metal core 2.Fig. 1 is that the preformed top wiring of all insulation of the utility model is whole
The fragmentary cross-sectional view of body structure, the cross sectional portion of left end are cross section, metal core 2 and insulating layer 3 in cross section corresponding diagram 1.
Use process are as follows: conducting wire is placed at the top of insulator in mounting groove, will be twined at the top of conducting wire and insulator with top wiring 1
Around being fixed together, then along the hand of spiral of top wiring 1, top wiring 1 is wrapped on conducting wire, makes conducting wire insertion top wiring
In 1 spiral helicine gap.
By there is the insulating layer 3 of plastics in 2 external sheath of metal core, the insulating layer 3 of plastics is not easy to fall, effectively prevent
Wiring 1 is pushed up to the abrasion of wire external layer and electric arc, electric discharge, the generation of ablation phenomen.Insulating layer 3 is not only coated on metal simultaneously
The side wall of core 2, phenomena such as being also coated on the end of metal core 2, electrochemical corrosion and electric arc, are easiest to occur at the end of top wiring 1
Portion, the utility model is also coated with insulating layer 3 in the end of metal core 2, more efficient to avoid electrochemical corrosion, electric arc, put
The generation of phenomena such as electricity, ablation, will not cause to corrode, ensure that safety to conducting wire.The utility model passes through prefabricated spiral shape,
Simplicity quick for installation, installation quality be easy to guarantee, realizing manually to install, while tailored appearance is beautiful.Insulating layer 3 and gold
Belong to core 2 to be an integral molding structure, can be fitted close and install with insulator, upward load can be effectively antagonized, prevent conducting wire
It takeoffs from insulator, prevents the generation of fly line phenomenon；Unstressed concentration after installation, grip force are distributed in longer region, can
It is effectively prevent the abrasion of conducting wire, is able to extend the service life of conducting wire.
Wherein the material of metal core 2 is iron, can be two iron wires to contact with each other, low cost and hardness is moderate, such as Fig. 1
Shown, the diameter of two iron wires is identical.Insulating layer 3 with a thickness of 0.5~3.5mm, insulating layer 3 uses PE (polyethylene), PVC
The plastic insulation materials such as (polyvinyl chloride) or FEP (fluorinated ethylene propylene copolymer) are made, i.e., plastics are PE, PVC or FEP.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and
Retouching also should be regarded as the protection scope of the utility model.
