Description
Technical field
This utility model relates to a kind of high-strength fire-retardant electric wire.
Background technology
Electric wire in the market, as being generally used for commercial electronic, electrical equipment and equipment and instrument internal connection line.Existing electric wire is typically to be made up of wire core and insulating bag covering layer, and wherein, wire stylet uses single bundle or multi beam copper cash to constitute, and insulating barrier uses different plastics to make according to requirements.Along with electrical equipment, electronic product develop to microminiaturization and multifunction, the requirement to electric wire is more and more higher, and many performances of existing electric wire cannot meet the demand in market.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of prior art, it is provided that a kind of high-strength fire-retardant electric wire.
The purpose of this utility model is achieved through the following technical solutions: a kind of high-strength fire-retardant electric wire, including conductor and the external insulation layer of coating conductor, described external insulation layer includes cross-linked polrvinyl chloride insulating barrier from inside to outside, fiberglass braided layer, Low Density Polyethylene silk braid, fluid insulation, fire-resistant sealing coat and thermosetting low smoke and zero halogen polyolefin layer, it is provided with tension silk in described cross-linked polrvinyl chloride insulating barrier, tension silk is extruded in polyimide insulative layer, the two ends of described conductor are respectively connected with a connection post, the outside of each connection post is all set with a lock sleeve, described lock sleeve is provided with wedge-shaped sleeve near one end of conductor Yu connector connecting portion, wedge-shaped sleeve is plugged between conductor and external insulation layer.
Described lock sleeve is threaded connection with being connected between post.
This utility model has the advantage that
Owing to cross-linked polrvinyl chloride insulating barrier is by cross-linking radiation mode, change the structure of the original strand of insulant, thus form new network structure, except having the performance of common polrvinyl chloride, it also has thermal shock resistance, abrasion resistance properties and the performance of antiacid alkali that common PVC is the most remarkable；Fiberglass braided layer, to the guarantee being more beneficial for circuit in the electronic equipment in normal phase hot operation, it is ensured that in the service life of electric wire, need not often change electric wire, thus reduce the cost of equipment；Low Density Polyethylene silk weaving, leaves space, contributes to the heat radiation of copper wire, increases the safety of electric wire；Making electric wire have good high temperature resistant, antioxidation by arranging fire-resistant sealing coat and thermosetting low smoke and zero halogen polyolefin layer, fire protecting performance is good.
By arranging tension silk, enhance the tensile property of electric wire.
Lock sleeve well seals the gap between conductor and external insulation layer, and the post that connects arranged facilitates the installation connection of electric wire.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of external insulation layer of the present utility model.
In figure, 1-conductor, 2-external insulation layer, 3-connector, 4-lock sleeve, 5-wedge-shaped sleeve, 6-cross-linked polrvinyl chloride insulating barrier, the fiberglass braided layer of 7-, 8-Low Density Polyethylene silk braid, 9-fluid insulation, the fire-resistant sealing coat of 10-, 11-thermosetting low smoke and zero halogen polyolefin layer, 12-tension silk.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further described:
Such as Fig. 1, shown in Fig. 2, a kind of high-strength fire-retardant electric wire, including conductor and the external insulation layer of coating conductor, described external insulation layer includes cross-linked polrvinyl chloride insulating barrier from inside to outside, fiberglass braided layer, Low Density Polyethylene silk braid, fluid insulation, fire-resistant sealing coat and thermosetting low smoke and zero halogen polyolefin layer, it is provided with tension silk in described cross-linked polrvinyl chloride insulating barrier, tension silk is extruded in polyimide insulative layer, the two ends of described conductor are respectively connected with a connection post, the outside of each connection post is all set with a lock sleeve, described lock sleeve is provided with wedge-shaped sleeve near one end of conductor Yu connector connecting portion, wedge-shaped sleeve is plugged between conductor and external insulation layer.
Described lock sleeve is threaded connection with being connected between post.
Owing to cross-linked polrvinyl chloride insulating barrier is by cross-linking radiation mode, change the structure of the original strand of insulant, thus form new network structure, except having the performance of common polrvinyl chloride, it also has thermal shock resistance, abrasion resistance properties and the performance of antiacid alkali that common PVC is the most remarkable；Fiberglass braided layer, to the guarantee being more beneficial for circuit in the electronic equipment in normal phase hot operation, it is ensured that in the service life of electric wire, need not often change electric wire, thus reduce the cost of equipment；Low Density Polyethylene silk weaving, leaves space, contributes to the heat radiation of copper wire, increases the safety of electric wire；Making electric wire have good high temperature resistant, antioxidation by arranging fire-resistant sealing coat and thermosetting low smoke and zero halogen polyolefin layer, fire protecting performance is good.
By arranging tension silk, enhance the tensile property of electric wire.
Lock sleeve well seals the gap between conductor and external insulation layer, and the post that connects arranged facilitates the installation connection of electric wire.
