Description
Technical field
The utility model relates to a kind of screen test with joining wiring more.
Background technology
Along with science and technology development, electronic industrial technology has also obtained development fast, and high-tech informationization technology forward people come up.
The separate unit display device is current very universal and be widely used.The progress of science, the development of society is stimulating also that people are higher to quality, the demand desire of the electronic equipment of better effects if, and constantly it is proposed higher more advanced requirement.Along with the rapid growth of social informatization, people also sharply enlarge the visual demand of information, and the informational function that the separate unit display device can show has lagged behind the demand of modern market people to visual information.Therefore, the large-screen splicing display system of screen test class, become information visualization must be obligato the key foundation system.At present, the application of screen test is very extensive, important places such as some Surveillance center, command centre, control centre particularly, to the demand of screen test, all become a kind of must obligato information hardware facility.Because the large-screen wall display system mostly is applied to the higher special applications place of performance requirement, therefore also very high to the reliability requirement of equipment, particularly be even more important to joining the transmission performance requirement of wiring more, more seeming.
, mainly have the following disadvantages aspect manufacturing technology with joining in the wiring at existing screen test: 1, the epidermis sheath generally adopts polyvinyl chloride to make more, and poor with the epidermis sheath flexibility that this material is made, the proof voltage effect is not fine, and stability is low.2, foaming insulation layer adopts the method for chemical blowing usually, and the foaming insulation layer foam degrees that obtains that foams in this way is not very high, and the radial dimension deviation is big.3, whole join in the wiring, screen has only one deck more, makes that like this effect of shielding is not fine.
The utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, provides a kind of softness, wear-resisting, proof voltage, humidity resistance good, Stability Analysis of Structures, and the screen test of shielding Functionality, quality and appealing design with joining wiring more.
The technical scheme that the utility model adopted is: the utility model comprises epidermis sheath, conducting metal mesh-like braiding II, plastic-aluminum band, connects heart yearn, described plastic-aluminum band the inside is enclosed with at least three described connection heart yearns, the outer surface of described plastic-aluminum band is being wrapped by described conducting metal mesh-like braiding II, described epidermis sheath wraps in the outer surface of described conducting metal mesh-like braiding II and is attached to the tight bag of described conducting metal mesh-like braiding II, and the physical characteristic of described epidermis sheath is the damp-proof wear-resistant elastomer.
Described connection heart yearn comprises conducting metal mesh-like braiding I, aluminium foil band, soft copper conductor, physic foaming insulation layer, crust again, described soft copper conductor, described physic foaming insulation layer, described aluminium foil band, described conducting metal mesh-like braiding I and described crust radially are provided with successively from inside to outside, and the physical characteristic of described crust also is the damp-proof wear-resistant elastomer.
Described aluminium foil band is two-sided aluminium foil band, and the above damp-proof wear-resistant elastomer all is the elastomer that is made by polyurethane material, and the wrappage of described plastic-aluminum band the inside also is enclosed with flexibility material filler except connecting heart yearn.
The beneficial effects of the utility model are: because elastomer is to be made by polyurethane material described in the utility model, the flexibility, good bending property, wear-resisting wiping, proof voltage and the moistureproof ability that join wiring have so just been improved more, make when laying construction, can be better, construction more easily, also improved the useful life that joins wiring more.Because what foaming insulation layer adopted is the manufacture method of described physical foam insulation, use such manufacture method can improve foam degrees and foaming thereof uniformity, reduce the deviation of radial dimension, under same frequency, electromagnetic reflection can be avoided or reduce to attenuation constant also than joining that wiring is little, return loss is big on the existing market, also more.Because more the screen that the shielding of described connection heart yearn adopts described two-sided aluminium foil band and described conducting metal mesh-like braiding I to combine makes screen test join wiring shielding attenuation value and reaches more than the 95dB, has also improved the structural stability of cable.Because the wrappage of described plastic-aluminum band the inside also is enclosed with described flexibility material filler except connecting heart yearn, just can guarantee that so also whole piece joins wiring rounding property in use more.Because polyurethane material has soft characteristic, make to join wiring when being subjected to bending or ambient pressure that inner structure keeps relative stability not fragile simultaneously more.Because the described crust surface in the described connection heart yearn also fixed packet is wrapped with plastic-aluminum band and conducting metal mesh-like braiding II, so just can play the effect of double layer screen with described conducting metal mesh-like braiding I one, improve the shielding attenuation performance that joins wiring more greatly.Through cable core with described be connected twice shielding of heart yearn after, make the inside of described connection heart yearn reach superpower shield effectiveness, guarantee that the high frequency audio video information transmits more in joining wiring, mask the electromagnetic interference of various pulse signals, AC signal and various frequencies.
Description of drawings
Fig. 1 is the utility model assembly structure cutaway view.
Embodiment
As Fig. 1 institute, the utility model comprises epidermis sheath 1, conducting metal mesh-like braiding II3, plastic-aluminum band 7, connects heart yearn 9, and described plastic-aluminum band 7 the insides are enclosed with five described connection heart yearns 9.Described connection heart yearn 9 comprises conducting metal mesh-like braiding I2, aluminium foil band 5, soft copper conductor 6, physic foaming insulation layer 8, crust 10 again, and described soft copper conductor 6, described physic foaming insulation layer 8, described aluminium foil band 5, described conducting metal mesh-like braiding I2 and described crust 10 radially are provided with successively from inside to outside.The outer surface of described plastic-aluminum band 7 is being wrapped by described conducting metal mesh-like braiding II3, described epidermis sheath 1 wraps in the outer surface of described conducting metal mesh-like braiding II3 and is attached to the tight bag of described conducting metal mesh-like braiding II3, and the physical characteristic of described epidermis sheath 1 and described crust 10 is the damp-proof wear-resistant elastomer.
