Abstract
The utility model discloses a kind of signal transmission cable, comprise conductor, conductor comprises 1 hollow core, hollow core has inner conductor, hollow core also possesses the internal ring portion of covering internal conductor, from described internal ring portion with multiple flanks of radiated entends, connect the outer portion of the outer end of described flank, have by described internal ring portion, multiple hollow bulbs that flank and outer portion are surrounded, conductor also comprises 4 twisted-pair feeders be arranged in parallel with hollow core, every root twisted-pair feeder is coated with the coating layer reducing friction, conductor is also coated with polyester belt outward successively, overcoat, almag silk screen and abrasion-proof insulating layer, overcoat comprises magnetic medium, adhesive and aluminium foil layer, magnetic medium sticks to aluminium foil layer surface by adhesive.This signal transmission cable bending performance well again can little effect Signal transmissions.
Description
Technical field:
The utility model relates to a kind of cable, is specifically a kind of 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, after being constantly folded over, through using for a long time, there will be line broken circuit, simultaneously because the wire that automobile uses is numerous, brings certain trouble to maintenance.
Utility model content:
Technical problem to be solved in the utility model is, provides a kind of bending performance well again can the signal transmission cable of little effect Signal transmissions.
Technical solution of the present utility model is, a kind of signal transmission cable is provided, comprise conductor, conductor comprises 1 hollow core, hollow core has inner conductor, hollow core also possesses the internal ring portion of covering internal conductor, from described internal ring portion with multiple flanks of radiated entends, connect the outer portion of the outer end of described flank, have by described internal ring portion, multiple hollow bulbs that flank and outer portion are surrounded, conductor also comprises 4 twisted-pair feeders be arranged in parallel with hollow core, every root twisted-pair feeder is coated with the coating layer reducing friction, conductor is also coated with polyester belt outward successively, overcoat, almag silk screen and abrasion-proof insulating layer, overcoat comprises magnetic medium, adhesive and aluminium foil layer, magnetic medium sticks to aluminium foil layer surface by adhesive.
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, in addition, 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, and antifriction insulating barrier improves the resistance to wear of wire.
As preferably, described coating layer is made by talcum powder.
As preferably, described insulating barrier is also coated with the reflective membrane being convenient to identify outward.Easy access.
Further, described insulating barrier is also coated with the reflective membrane being convenient to identify outward.Identification when being beneficial to maintenance.
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 signal transmission cable, comprise conductor, conductor comprises 1 hollow core 1, hollow core 1 has inner conductor 11, 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 4 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, coating layer 3 is made by talcum powder, conductor is also coated with polyester belt 4 outward successively, overcoat 5, almag silk screen 6 and abrasion-proof insulating layer 7, overcoat 5 comprises magnetic medium, adhesive and aluminium foil layer, magnetic medium sticks to aluminium foil layer surface by adhesive, described abrasion-proof insulating layer 7 is made by modifying character for PVC material.For convenience of identification wire, insulating barrier 7 is outer is also coated with the reflective membrane being convenient to identify, easily picks out the trend of wire like this when overhauling.
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.
