Description

C shield shielding cable

Technical Field

The utility model relates to a high frequency signal wire rod field, in particular to C shield shielding cable.

Background

At present the cable is the direct insulating layer of parcel in the heart yearn outside more, and the signal cable still need be equipped with and weave the shielding layer, and the netted shielding layer of weaving of traditional signal cable generally uses tinned copper wire or almag to weave the silk as shielding material, and in actual production, the customer also can detect the electromagnetic shield effect of wire rod.

When the traditional signal cable shielding material is tested, the electromagnetic leakage phenomenon can occur due to the limitation of material performance, and the signal transmission of the cable is influenced.

SUMMERY OF THE UTILITY MODEL

The utility model provides a solve above-mentioned problem, provide a C shield shielding cable, get rid of the woven shield layer of original cable, adopt the C shield as the shielding layer, when reduce cost, improved the EMI performance of cable again to, this cable tensile strength is high, and bending ability is good, is difficult for the rupture, possesses better electromagnetic shielding performance.

In order to achieve the above purpose, the utility model adopts the technical scheme that: the utility model provides a C shield shielding cable, includes by outer to interior outer quilt, C shield layer and heart yearn, and C shield layer is the composite bed on aluminium foil layer and carbon system wave-absorbing layer, and both pass through adhesive bonding, and the whole thickness in C shield layer is 0.04mm 0.003mm, and the heart yearn is the high frequency signal transmission heart yearn.

Furthermore, the core wire includes an HDMI line, a Display port signal line, and a USB3.0/USB3.1 signal line.

To sum up, the utility model discloses possess following advantage:

the utility model discloses get rid of the woven shield layer of original cable, adopt the aluminium foil that punches as the shielding layer, when reduce cost, improved the EMI performance of cable again to, this cable tensile strength is high, and bending capability is good, and difficult rupture possesses better electromagnetic shielding performance.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Detailed Description

The invention will be further described with reference to the following drawings and examples:

example 1:

a C shield shielding cable is shown in figure 1 and comprises an outer cover 1, a C shield layer 2 and a core wire 3 from outside to inside.

Specifically, for the composite bed on aluminium foil layer and carbon system absorbing layer, both pass through adhesive bonding, the whole thickness on C shield layer 2 is 0.04mm 0.003mm, replaces the weaving layer, effectual save material, reduction in production cost possesses good electromagnetic shield effect to can effectual improvement EMI effect.

The improvement of cable EMI is just drainage and shielding, guides out the electromagnetic wave and shields the electromagnetic wave simultaneously, and C shield layer 2 is taken into account the drainage shielding and can also absorb the electromagnetic wave simultaneously, replaces the metal mesh grid, can reach save material and artifical and improve EMI's effect.

The core wire 3 is a high frequency signal transmission core wire, which includes an HDMI wire, a Display port signal wire, and a USB3.0/USB3.1 signal wire.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; the two components can be directly connected or indirectly connected through an intermediate medium, and the two components can be communicated with each other.

The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

It will be understood that the above-described embodiments are illustrative only and not restrictive, and that various obvious and equivalent modifications and substitutions may be made in the details described herein by those skilled in the art without departing from the basic principles of the invention.
