Abstract

The utility model discloses a vehicle-mounted electronic connecting wire which comprises a power wire, an image wire, two signal wires and an outer protective layer, wherein the power wire, the image wire and the signal wires are all wrapped in the outer protective layer; it integrates multiple function cable, but double shielding does not influence signal transmission.

Description

Vehicle-mounted electronic connecting line

Technical Field

The utility model relates to the technical field of manufacturing of wires and cables, in particular to a vehicle-mounted electronic connecting wire.

Background

The electrical parts on the car are more and more, the use of signal cable also increases thereupon, need concentrate the wiring at same pipeline, thereby can influence each other between each cable, mutual interference, present anti-interference cable conductor adopts single face aluminium foil parcel cooperation copper wire stranded conductor to realize shielding effect more, can only realize that external signal advances not to go or internal signal goes out never, with the effect of shielding anti-jamming is realized, but is unsatisfactory to the shielding effect between the heart yearn in the pencil, also can influence shielded cable's whole result of use, cause signal transmission performance poor.

SUMMERY OF THE UTILITY MODEL

In view of the above, the present invention is directed to a vehicle-mounted electronic connection line, which integrates a multi-function cable, can be shielded doubly, and does not affect signal transmission.

In order to achieve the purpose, the utility model adopts the following technical scheme:

the utility model provides an on-vehicle electronic connection line, includes power cord, image line, two signal lines and outer jacket, power cord, image line, two signal lines all wrap in the outer jacket, the equal cladding of power cord, image line and signal line has the insulating layer, power cord and image line form first core group, the outer winding of first core group has first shielding layer, the outer cladding of first shielding layer has two-layer two-sided aluminium foil, two the signal line forms second core group, the outer winding of second core group has the second shielding layer, the outer cladding of second shielding layer has the two-sided aluminium foil of one deck.

Preferably, the thickness of the double-sided aluminum foil is 30 μm.

Preferably, the material of the shielding layer is tinned copper wire.

As a preferred scheme, the diameter of the connecting wire is 3.5-7.0 mm.

As a preferred scheme, an inner protection layer is arranged between two layers of double-sided aluminum foils wrapped outside the first shielding layer.

Preferably, an inorganic filler is filled between the power line and the image line and between the two signal lines.

Preferably, the outer protective layer is made of a PVC material.

Compared with the prior art, the utility model has obvious advantages and beneficial effects, and particularly, according to the technical scheme, the double-sided aluminum foil is coated outside the second core wire group, the two layers of double-sided aluminum foils are coated outside the first core wire group, and the functional cables are separately arranged, so that the shielding effect is better, the normal use of each function of an automobile can be met, the mutual shielding among the multifunctional cables is realized, the signal transmission is not influenced, and the signal transmission quality is improved.

To more clearly illustrate the structural features and effects of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

Drawings

FIG. 1 is a schematic structural diagram of an embodiment of the present invention.

The attached drawings indicate the following:

10. a power line; 11. an image line; 12. a signal line; 13. an outer jacket; 14. an insulating layer; 15. A first core wire group; 16. a first shielding layer; 17. double-sided aluminum foil; 18. a second core wire set; 19. an inner protective layer; 20. an inorganic filler; 21. and a second shielding layer.

Detailed Description

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the positions or elements referred to must have specific orientations, be constructed in specific orientations, and be operated, and thus, should not be construed as limiting the present invention.

In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood as appropriate by those of ordinary skill in the art.

Referring to fig. 1, a specific structure of an embodiment of the present invention is shown, which includes a power line 10, an image line 11, two signal lines 12 and an outer sheath 13, where the power line 10, the image line 11 and the two signal lines 12 are all covered in the outer sheath 13, the power line 10, the image line 11 and the signal lines 12 are all covered with an insulating layer 14, the power line 10 and the image line 11 form a first core set 15, the first core set 15 is covered with a shielding layer, the shielding layer is covered with two layers of double-sided aluminum foils 17, the two signal lines 12 form a second core set 18, and the second core set 18 is covered with a layer of double-sided aluminum foils 17.

In the present embodiment, the thickness of the double-sided aluminum foil 17 is 30 μm. The shielding layer is made of a tinned copper wire. The diameter of the connecting wire is 3.5-7.0 mm. An inner protective layer 19 is arranged between two layers of double-sided aluminum foils 17 wrapped outside the first shielding layer 16. Inorganic filler 20 is filled between the power line 10 and the image line 11 and between the two signal lines 12. The outer protective layer 13 is made of PVC material. In summary, the double-sided aluminum foil is coated outside the second core wire set, the two layers of double-sided aluminum foils are coated outside the first core wire set, and the functional cables are arranged separately, so that the shielding effect is better, the normal use of each function of an automobile can be met, the mutual shielding among the various functional cables is realized, the signal transmission is not influenced, and the transmission quality is improved.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the technical scope of the present invention, so that any minor modifications, equivalent changes and modifications made to the above embodiment according to the technical spirit of the present invention are within the technical scope of the present invention.
