Description

A kind of multicore shielding cable

Technical field

The utility model is related to shielded cable technical field, more particularly to a kind of multicore shielding cable.

Background technology

For shielded cabling systems derived from Europe, it is plus metal screen layer, profit in the outside of common unmasked wiring system Prevent electromagnetic interference and the function of electromagnetic radiation, shielding harness comprehensive with reflection, absorption and the Kelvin effect realization of metal screen layer The shielding action of the equilibrium principle that twisted-pair feeder is utilized and shielded layer is closed, thus with extraordinary electromagnetic compatibility (EMC) characteristic The utility model is suitable for all band aluminum foil shielded cables, specifically such as:Multicore shielding cable, USB series cables, HDMI series lines Cable etc..

At present, in existing multicore shielding cable, shielding construction is all longitudinal wrap aluminium foil, it is most of be all need with Lower workshop section:Conductor twists copper, insulation core wire extrusion, all core wire set always twist, longitudinal wrap aluminium foil, outer by extrusion.Due to aluminium foil longitudinal wrap It overlaps afterwards with core wire after wire rod set, when set core wire has gap, aluminium foil can be inwardly recessed, when producing outside by extrusion Required sizing material is more, and cost increases, and increases total wire rod cost.When needing a kind of core wire set has gap, aluminium foil will not be inside It is recessed, the outer sizing material needed for extrusion is reduced, reduces the multicore shielding cable of wire production cost.

Utility model content

The utility model is mainly solving the technical problems that provide a kind of multicore shielding cable, a kind of USB-Type C Cable, it is ensured that the parameters such as wire properties impedance, delay difference, attenuation are stablized, and prevent external interference, prevent transmission signal It loses.

To solve the above-mentioned problems, the utility model provides a kind of multicore shielding cable, including crust, aluminium foil layer, core wire, Insulating layer, the core wire are equipped with conducting wire, wire sheath, and a plurality of core wire is arranged in circle in its section, there is insulating layer outside, It is wrapped up by aluminium foil layer, aluminium foil layer is wrapped up by crust, and the aluminium foil layer is aluminium foil material, and the aluminium foil layer is to core wire and insulating layer It wraps up as reversed wrapped aluminium foil structure.

Furtherly, the conducting wire is copper wires.

Furtherly, the insulating layer is PVC material.

Furtherly, the core wire can be four, be divided into black, white, red, green color.

In use, since aluminium foil layer is reversed wrapped aluminium foil structure to the package of core wire and insulating layer, so when core wire collection When conjunction has gap, aluminium foil will not be inwardly recessed, and unitary set core wire reduces the outer sizing material needed for extrusion, drop by basis of rounding Low wire production cost.

The beneficial effects of the utility model are：When core wire set has gap, aluminium foil will not be inwardly recessed, unitary set Core wire is reduced the outer sizing material needed for extrusion, is reduced wire production cost based on rounding.

Description of the drawings

It in order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, and the attached drawing in describing is this practicality Some novel embodiments, to those skilled in the art, without creative efforts, can be with Other accompanying drawings are obtained according to these attached drawings.

Fig. 1 is the diagrammatic cross-section of the utility model cable.

With reference to embodiment, and with reference to attached drawing, the realization of the utility model aim, functional characteristics and advantage are made into one Walk explanation.

Specific embodiment

In order to make the purpose, technical scheme and advantage of utility model clearer, implement below in conjunction with the utility model Attached drawing in example, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that described reality It is utility model part of the embodiment to apply example, instead of all the embodiments.Based on the embodiment in the utility model, this field It is new to belong to this practicality for those of ordinary skill's all other embodiments obtained under the premise of creative work is not made The range of type protection.

Embodiment one

Refering to shown in attached drawing 1, a kind of multicore shielding cable, including crust 1, aluminium foil layer 2, core wire 3, insulating layer 4, institute Core wire 3 is stated equipped with conducting wire 31, wire sheath 32, a plurality of core wire 3 is arranged in circle in its section, there is insulating layer 4 outside, It is wrapped up by aluminium foil layer 2, aluminium foil layer 2 is wrapped up by crust 1, and the aluminium foil layer 2 is aluminium foil material, and the aluminium foil layer 2 is to 3 He of core wire The package of insulating layer 4 is reversed wrapped aluminium foil structure.

Specifically：Since aluminium foil layer 2 is reversed wrapped aluminium foil structure to the package of core wire 3 and insulating layer 4, so working as core wire When set has gap, aluminium foil will not be inwardly recessed, and unitary set core wire 3 reduces the outer sizing material needed for extrusion by basis of rounding, Reduce wire production cost.

Refering to shown in attached drawing 1, the conducting wire 31 is copper wires.

Refering to shown in attached drawing 1, the insulating layer 4 is PVC material.

Refering to shown in attached drawing 1, the core wire 3 can be four, be divided into black, white, red, green color.

Above example is only to illustrate the technical solution of the utility model, rather than its limitations；Although with reference to aforementioned reality Example is applied the utility model is described in detail, it will be understood by those of ordinary skill in the art that：It still can be to preceding The technical solution recorded in each embodiment is stated to modify or to which part technical characteristic progress equivalent replacement, and these Modifications or substitutions, the spirit and model of various embodiments of the utility model technical solution that it does not separate the essence of the corresponding technical solution It encloses.
