Abstract
The utility model discloses a kind of vehicle signal transmission cable, comprise conductor, conductor is coated with polyester belt outward successively, overcoat, almag silk screen and insulating barrier, conductor comprises a core body and four twisted-pair feeders, core body is hollow core, every root twisted-pair feeder is coated with the coat reducing friction, also overcoat is provided with between polyester belt and almag silk screen, overcoat comprises magnetic medium, adhesive and aluminium foil layer, magnetic medium sticks to aluminium foil layer surface by adhesive, insulating barrier outer surface be provided with multiple can along the hanger of conductor length direction movement, also be provided with between hollow core and polyester belt and help tearing tape.This vehicle signal transmission cable bending performance well again can little effect Signal transmissions, and conveniently tears cable epidermis.
Description
Technical field:
The utility model relates to a kind of cable, is specifically a kind of vehicle signal transmission cable.
Background technology:
Along with the development of auto industry, increasing use digital data transmission, the demand connecting the wire of these components and parts also increases thereupon, due to the restriction in the space of automobile own, a lot of wire in use needs to bend back and forth, this proposes very high requirement to the bending performance of wire, and especially the wire of Signal transmissions, easily occurs signal attenuation after bending.Existing wire is after being constantly folded over, through using for a long time, there will be line broken circuit, again connect terminal needs each other by instrument wire stripping when there is cable fault simultaneously, certain trouble is brought, in addition, when vehicle signal transmission cable is fixed in car to maintenance, tighten often through band, this Signal transmissions for cable also can bring certain impact.
Utility model content:
Technical problem to be solved in the utility model is, provides a kind of vehicle signal transmission cable of little effect Signal transmissions, and this transmission cable can not affect signal transmission effect when binding, and this transmission cable is easy to wire stripping, convenient connection.
Technical solution of the present utility model is, a kind of vehicle signal transmission cable is provided, comprise conductor, conductor is coated with polyester belt outward successively, overcoat, almag silk screen and insulating barrier, conductor comprises a core body and four twisted-pair feeders, core body is hollow core, every root twisted-pair feeder is coated with the coat reducing friction, also overcoat is provided with between polyester belt and almag silk screen, overcoat comprises magnetic medium, adhesive and aluminium foil layer, magnetic medium sticks to aluminium foil layer surface by adhesive, insulating barrier outer surface be provided with multiple can along the hanger of conductor length direction movement, also be provided with between hollow core and polyester belt and help tearing tape.
To adopt after above structure compared with prior art, the utility model has the following advantages: the insulating barrier of original core body is designed to hollow structure by solid infill, dielectric constant is reduced with this, because dielectric constant is higher, transmission speed is slower, the loss of signal is more, so attenuation degree when hollow core effectively can reduce Signal transmissions, at the coat that twisted-pair feeder applies outward, the phase mutual friction between twisted-pair feeder can be reduced, reduce the impact that bending brings, the impact on Signal transmissions is reduced as far as possible when bending, hanger is provided with outside insulating barrier, when needs are bound, just can be fixed by hanger, and again band need not be bundled on cable and suppress Signal transmissions, thus reduction loss of signal.When needs connection cable joint, conveniently exocuticle can be torn by helping tearing tape.
As preferably, described coat is made by talcum powder.
As preferably, described hollow core has inner conductor, hollow core also possess covering internal conductor internal ring portion, from described internal ring portion with multiple flanks of radiated entends, the outer portion connecting the outer end of described flank, have by described internal ring portion, flank and outer portion surround multiple hollow bulbs.
Further, spring hose is arranged with outside described hollow core.Further raising bend resistance performance, reduces the loss of signal when bending.
Accompanying drawing illustrates:
Fig. 1 is generalized section of the present utility model.
Fig. 2 is the cross-sectional view of hollow core.
Embodiment:
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
As depicted in figs. 1 and 2, a kind of vehicle signal transmission cable, comprise conductor, conductor is also coated with polyester belt 4 outward successively, overcoat 5, almag silk screen 6 and insulating barrier 7, conductor comprises a hollow core 1, spring hose 8 is arranged with outside hollow core 1, hollow core 1 has inner conductor 11, inner conductor 11 is copper wire, hollow core 1 also possesses the internal ring portion 12 of covering internal conductor, from described internal ring portion 12 with multiple flanks 14 of radiated entends, connect the outer portion 13 of the outer end of described flank 14, formed by described internal ring portion 12, multiple hollow bulbs that flank 14 and outer portion 13 are surrounded, conductor also comprises four twisted-pair feeders 2 be arranged in parallel with hollow core 1, every root twisted-pair feeder 2 is coated with the coating layer 3 reducing friction, coat 3 is made by talcum powder, overcoat 5 comprises magnetic medium, adhesive and aluminium foil layer, magnetic medium sticks to aluminium foil layer surface by adhesive, insulating barrier 7 outer surface be provided with multiple can along the hanger 9 of conductor length direction movement, also be provided with between hollow core 1 and polyester belt 4 and help tearing tape 10.Hanger 9 is slided into corresponding fixed position, be then fixed with band or other frenulums.Tear for convenience, help and tear 10 bands and can arrange multiple, preferably establish between two adjacent twisted-pair feeders 2 and polyester belt 4 and help tearing tape 10, establish between hollow core 1 and adjacent twisted-pair feeder 2 simultaneously and help tearing tape 10.
Below be only described with regard to the utility model preferred embodiment, but can not be interpreted as it is limitations on claims.Every utilize the utility model specification and accompanying drawing content to do equivalent structure or equivalent flow process conversion, include within scope of patent protection of the present utility model.
