Abstract

The utility model relates to an improved cable structure which comprises a first conductor, a second conductor and a coating unit, wherein the second conductor is arranged at one side of the first conductor, and the coating unit is coated outside of the first conductor and the second conductor so that a central distance between the first conductor and the second conductor is a stable distance; moreover, a planar part is arranged at one side of the coating unit, a concave part at the other side is arranged between the first conductor and the second conductor. The improved cable structure has the advantages that the zero delay difference of transmission time is achieved when a high-frequency signal is transmitted.

Description

The modified model cable structure

Technical field

The utility model relates to a kind of cable structure, specifically, is a kind of modified model cable structure of transmitting high-frequency signal.

Background technology

See also Fig. 4 and Fig. 5, Fig. 4 is known cable profile status schematic diagram, Fig. 5 is known cable pair twist view, general known cable (as shown in Figure 4 and Figure 5) when carrying out audio-visual high-frequency signal transmission, its with two

heart yearns

6,7 side by side after, carry out pair twist again, utilize two

heart yearns

6,7 as audio-visual high-frequency signal transmission to reach.

Though mode with two

heart yearn

6,7 pair twists, can be used as the usefulness of audio-visual high-frequency signal transmission, but because the center distance d of its each

conductor

61,71 size can produce deviation because of the elasticity and the stability of pair twist behind two heart yearns, 6,7 pair twists, it is little when time thes be big, and the center distance d that can't make each

conductor

61,71 remains in more stable distance, thereby cause the lifting or the decline of impedance, cause the high-frequency signal transmission time to have and postpone the unstable of difference or the generation of variation situation, make the characteristic of described cable when carrying out audio-visual high-frequency signal transmission relatively poor.

Therefore known audio-visual high-frequency signal transmission wire cable structure exists above-mentioned all inconvenience and problem.

Summary of the invention

The purpose of this utility model, when being to propose a kind of high-frequency signal transmission, but the active balance impedance, and reach the modified model cable structure of transmission time zero-lag difference.

For achieving the above object, technical solution of the present utility model is:

A kind of modified model cable structure comprises one first conductor, one second conductor and a coating unit, wherein,

Described second conductor is arranged at described first conductor, one side;

Described coating unit, it is the outside that one is coated on described first and second conductor, the center distance that makes described first and second conductor is a stabilizing distance, and have a planar portions on the one side of described coating unit, and have the depressed part of being located between described first and second conductor on the another side.

Modified model cable structure of the present utility model can also be further achieved by the following technical measures.

Aforesaid modified model cable structure, two sides of wherein said coating unit have a cambered surface portion respectively.

Aforesaid modified model cable structure can be provided with an earth connection in the depressed part of wherein said coating unit, and the outside of described coating unit and described earth connection is coated with a screen, and the outside of described screen is coated with an insulating barrier.

Aforesaid modified model cable structure, wherein said screen can be an aluminium foil wheat drawstring, and the one side of described aluminium foil wheat drawstring conduction contacts with earth connection.

After adopting technique scheme, modified model cable structure of the present utility model has the advantage that reaches transmission time zero-lag difference when carrying out high-frequency signal transmission.

Embodiment

Below in conjunction with embodiment and accompanying drawing thereof the utility model is illustrated further.

Now see also Fig. 1 and Fig. 2, Fig. 1 is the three-dimensional appearance schematic diagram of the utility model embodiment, and Fig. 2 is the profile status schematic diagram of the utility model embodiment.As shown in the figure, described second conductor, 2 adjacent sides that are arranged at described first conductor 1.

Described coating unit 3 is outsides that one is coated on described first and

second conductor

1,2, the center distance D that makes described first and

second conductor

1,2 is a stabilizing distance, and has a planar portions 31 on the one side of described coating unit 3, and have the depressed part of being located between first and

second conductor

1,2 32 on the another side, and has a cambered surface portion 33 respectively in two sides of described coating unit 3.Thus, constitute a brand-new modified model cable structure by said structure.

See also Fig. 3 again, Fig. 3 is the user mode schematic diagram of the utility model embodiment.As shown in the figure, during the utility model utilization, can in the depressed part 32 of described coating unit 3, be provided with an earth connection 4, and described coating unit 3 is coated with a screen 5 with the outside of described earth connection 4, and the outside of described shielding layer 5 is coated with an insulating barrier 6, wherein said screen 5 can be an aluminium foil wheat drawstring, and the one side of described aluminium foil wheat drawstring conduction contacts with described earth connection 4; And when cable of the present utility model uses as audio-visual high-frequency signal transmission, because described first and

second conductor

1,2 is no matter in any position or how to bend, its center distance D all can keep stabilizing distance, and described first and

second conductor

1,2 also is all isometric on length, therefore, can make described cable structure utilize the cooperation of this characteristic, when carrying out high-frequency signal transmission, reach transmission time zero-lag difference effect.

Above embodiment is only for the usefulness that the utility model is described, but not to restriction of the present utility model, person skilled in the relevant technique under the situation that does not break away from spirit and scope of the present utility model, can also be made various conversion or variation.Therefore, all technical schemes that are equal to also should belong to category of the present utility model, should be limited by each claim.
