Description
Technical field
The utility model relates to a kind of telecommunication cable of the transmission of the numeric class for automotive interior.
Background technology
Coaxial cable is by inner and be divided into center copper cash, plastic insulation, netted conductive layer and wire outer skin outward, and center copper cash and netted conductive layer form current circuit, because center copper cash and netted conductive layer are the coaxial relation coaxial cable of gaining the name.
If use general electric wire carry high frequency rate electric current, this electric wire will be equivalent to an outwards wireless antenna of transmitting, this effect loss the power of signal, the signal strength signal intensity receiving is reduced.The center copper cash of coaxial cable and netted conductive layer form current circuit, and the radio that center wire emits is isolated by netted conductive layer, and netted conductive layer can be controlled the radio emitting by the mode of ground connection.Coaxial cable can be supported high-bandwidth communication on the circuit of relatively long non-relay device, exactly in order to address the above problem.
But in order to ensure reliability, the diameter of cablet just reaches 3/8 inch (being 9.525mm), volume is large, quality weight, not only needs to take the large quantity space of cable duct, and can cause occurring that flexibility is excessively poor, and difficult wiring in automobile is strengthened; If extruding or torsional deformation that a certain section of generation of cable is larger, the distance between center wire and netted conductive layer will change so, causes inner radio wave can be reflected back toward signal transmission source, has reduced receivable signal power.
Utility model content
In view of this, the utility model provides a kind of telecommunication cable for automobile, in ensureing the bending property of cable, has greatly reduced cable diameter.
The technical solution adopted in the utility model is specially: a kind of telecommunication cable, comprise body and core body, and described core body comprises coaxial body, derives core and supporter, between described coaxial cable, described derivation core and described supporter, is provided with filler.
Described supporter at least comprises two insulators, and each described insulator comprises conductor thread core and core insulating barrier from inside to outside successively.
Described conductor thread core is the many stranded twisted wires that form of single line.
The diameter of section of multiple described insulators is identical.
The diameter of section difference of multiple described insulators.
Described insulator is insulated wire cores.
Described coaxial cable comprises inner wire, insulating barrier, outer conductor and core sheath from inside to outside successively; Described inner wire is coaxial core, and described outer conductor is for being wound around screen.
Described coaxial core and described derivation core are the many stranded twisted wires that form of single line.
Described body comprises vertical aluminium foil and cable cover(ing) from inside to outside successively.
The external diameter of described cable is 4.5-5.5mm.
The beneficial effect that the utility model produces is:
On the basis of coaxial cable of the present utility model, ensure distance between them consistently by insulator is set, overcome that cable is stiff does not allow flexible defect, efficiently solve the problems such as coaxial cable volume is large, bending property is poor; In addition the utility model has adopted and has been wound around shielding, vertical bag shielding and derives three kinds of shieldings of core, signal is decayed in transmitting procedure little, is also not easy to be subject to external disturbance, has ensured the clear accuracy of signal transmission.
Brief description of the drawings
When considered in conjunction with the accompanying drawings, can more completely understand better the utility model.Accompanying drawing described herein is used to provide further understanding of the present utility model, and embodiment and explanation thereof are used for explaining the utility model, does not form to improper restriction of the present utility model, wherein:
Fig. 1 is a kind of low pressure coaxial cable for automobile of the utility model;
Fig. 2 is the flow process chart of a kind of low pressure coaxial cable for automobile of the utility model.
In figure: 1, coaxial core; 2, insulating barrier; 3, be wound around screen; 4, core sheath; 5, the first insulator; 6, the second insulator; 7, conductor thread core; 8, core insulating barrier; 9, derive core; 10, vertical aluminium foil; 11, cable cover(ing).
Embodiment
Below in conjunction with drawings and Examples, the technical solution of the utility model is described in further detail.
A kind of telecommunication cable as shown in Figure 1, comprises body and core body, and core body comprises coaxial body, derives core 9 and supporter, between coaxial cable, derivation core 9 and supporter, is provided with filler; Wherein:
Supporter at least comprises two insulators, each insulator comprises conductor thread core 7 and core insulating barrier 8 from inside to outside successively, insulator can be also the independent insulated wire cores that does not need sheath in addition, the diameter of section of multiple insulators can be identical, also can be according to actual conditions, be designed to the different cross section of diameter.In the present embodiment, comprise that supporter comprises two insulators that sectional area is identical, i.e. insulator 1 and insulator 26;
Coaxial cable comprises inner wire, insulating barrier 2, outer conductor and core sheath 4 from inside to outside successively; In the present embodiment, inner wire is coaxial core 1, and outer conductor is for being wound around screen 3;
Body comprises vertical aluminium foil 10 and cable cover(ing) 11 from inside to outside successively, and vertical aluminium foil is as adopted the wide filtering of 0.025 thickness × 14mm to indulge bag.
Coaxial core 1, conductor thread core 7 and derivation core 9 are the many stranded twisted wires that form of single line, and particularly, in the present embodiment, coaxial core 1, conductor thread core 7 and derivation core 9 all adopt 17 stranded forming of the soft circular copper wire of 0.16mm, meet electric wire soft structure.
The concrete technology of the telecommunication cable of said structure as shown in Figure 2, wherein bunch is mainly that copper single line bundle is closed and makes the strand of multiple twisted wire or directly as conductor, extruding insulation is at conductor outer cladding plastic eraser energy high polymer insulating material, stranding (laying up pitch in the present embodiment is 36 ± 3mm) is that many insulated wire cores are twisted together, make cable rounding, improve the bending property of cable, vertical aluminium foil and winding shielding have been all effects of shielding interference signal, extruding (being that 85 DEG C of PVC extrude in the present embodiment) sheath is at insulated wire cores or shielding core outer cladding plastics or rubber, play the object of protection insulated wire cores.
The cable that shown processes goes out, compare to current coaxial cable external diameter and be at least 9.525mm, external diameter can be as small as 4.5-5.5mm, is significantly less than the coaxial transmission cable (having reduced more than 50%) on existing market, is conducive to the saving at automotive interior wiring time space.
As mentioned above; embodiment of the present utility model is explained; obviously, as long as do not depart from fact inventive point of the present utility model and effect, the distortion that will be readily apparent to persons skilled in the art, within being all included in protection range of the present utility model yet.
