Abstract

The utility model relates to a double layer insulated wire for lamps, comprising a wire core and a double decked insulation layer. The cable core is a plurality of tin-plated copper conductors, nickel-plated copper conductors or silver-plated copper conductors. The double decked insulation layer is the outer covering insulation layer of the wire. The insulation layer has an inner layer structure and an outer layer structure. The material of the insulation layer is the silicone rubber or the FEP poly perfluoroethylene or the PFA soluble polytetrafluoroethylene. The wire of the utility model has the advantage of stronger pressure resistance when the thickness of the insulation layer is the same.

Description

A kind of lamp decoration double hyer insulation electric wire

Technical field:

The utility model relates to a kind of lamp decoration double hyer insulation electric wire, especially uses line as being electrically connected of lamp decoration product lamp holder.

Background technology:

Be used in being electrically connected in the lamp decoration product at present and use line, mostly be PVC, the FEP polyfluorinated ethylene, PFA soluble poly tetrafluoroethene or silicon rubber individual layer insulated electric conductor, because the environment that the lamp decoration product lamp holder is electrically connected is narrow and special-shaped, the electric current that electric loop is flowed through is bigger, make junction temperature height, the electrical safety of lamp decoration product itself requires high in addition, make the electrical cable of its lamp holder require high pressure resistant, high temperature resistant, used electrical cable is for adapting to above-mentioned requirements, behind selected high-temperature resistant insulating material, often adapt to the specific (special) requirements that the lamp decoration lamp holder is electrically connected by merely increasing thickness of insulating layer, make this kind connection greatly increase with line insulating layer thickness, cause threading in the application, wire stripping inconvenience, and electric wire cost height.

Summary of the invention:

According to the problem of above-mentioned existence, the purpose of this utility model is to provide a kind of lamp decoration double hyer insulation electric wire, both has been fit to the requirement that the lamp decoration product lamp holder is electrically connected, and the thickness of insulating layer than the individual layer insulated electric conductor that uses identical withstand voltage level is little again.

For achieving the above object, the utility model provides a kind of lamp decoration double hyer insulation electric wire, comprising: core also comprises: double-deck insulating barrier;

Qualification according to lamp decoration lamp holder electrical cable electric requirement and dimensional requirement, the external insulation layer of one deck same dielectric material again is covered on individual layer insulated electric conductor insulating barrier existing, thinner thickness, and make this double-deck insulating barrier integral thickness under identical withstand voltage level than monolayer insulating layer thin thickness, just make the utility model;

As a kind of improvement of the present utility model, the external insulation layer of one deck same dielectric material that is covered again on the withstand voltage insulating barrier electric wire of individual layer will make the electric wire withstand voltage level higher than the individual layer insulation of same dielectric layer thickness.

Under same dielectric thickness, double-layer insulating structure is than single layer structure withstand voltage level height, and its principle is: under the identical condition of exerting pressure, double-layer insulating structure has more superior voltage gradient curve than individual layer insulation system.

Simultaneously, in the application of lamp decoration product, sometimes, electric wire insulation layer need be peeled off half so that reality connects, the individual layer insulated electric conductor is difficult for realizing that the double hyer insulation composite wire then can satisfy this application requirements easily.

Therefore, under the lamp decoration product service condition that is equal to, electric wire is by withstand voltage double hyer insulation composite construction, to the insulation thickness of used electric wire be reduced relatively, and can make things convenient for the use of lamp decoration product to connect, perhaps, under same dielectric thickness, the high-temperature resistant double-layer insulated electric conductor then can bear higher withstand voltage level, makes lamp decoration product safer;

Description of drawings:

Fig. 1 is the structural diagrams of the utility model composite wire

The accompanying drawing sign:

Core 1, internal layer is withstand voltage insulating barrier 2, outer withstand voltage insulating barrier 3,

Embodiment:

In order to further specify above-mentioned purpose of the present utility model, structure and effect, embodiment of the present utility model is described below in conjunction with accompanying drawing.

Fig. 1 is the structural diagrams of the utility model composite wire, comprising: core 1, internal layer is withstand voltage insulating barrier 2, outer withstand voltage insulating barrier 3;

Described core 1 is the multiply tinned wird, and described internal layer is withstand voltage, and insulating barrier 2 and outer withstand voltage insulating barrier 3 materials adopt the FEP polyfluorinated ethylene; Under specific process conditions, to the single-layer wire of the FEP polyfluorinated ethylene insulating barrier 2 that is covered, the outer withstand voltage insulating barrier 3 of one deck same material that is covered again on its external insulation just is the utility model product

Example as the double-deck withstand voltage insulating barrier composite wire of the utility model, inner insulating layer 0.6mm, external insulation be the silicone rubber wire of 0.7mm gauge layer by layer, its withstand voltage test can be by experimental condition: 2 hours 6000V of immersion normal temperature (revising 8) voltage test, and more superior than stack pile individual layer insulated electric conductor withstand voltage properties.

The double-deck withstand voltage insulating barrier composite wire of the utility model can be widely used in makes the lamp holder electrical cable in the various lamp decoration products.
