Description

signal transmission cable

1. Technical field

The utility model relates to a cable, in particular to a signal transmission cable.

2. Background technology

Generally, the signal transmitted by the signal transmission cable is very small. In order to avoid signal interference, there is a shielding layer outside the signal transmission cable. The shielding layer of the wrapped conductor is generally conductive cloth, braided copper mesh or copper mooring. The shielding layer needs to be grounded. The interference signal can be guided into the ground by this layer, preventing the interference signal from entering the inner layer conductor interference and reducing the loss of the transmission signal. 3. Contents of the invention

The purpose of this utility model is to provide a signal transmission cable for the above-mentioned defects existing in the prior art.

Its technical scheme is: including outer sheath, inner insulation layer, shielding layer, wire core, filling layer, outer insulation layer, the outside of the wire core is provided with an inner insulation layer, multiple groups of wire cores are twisted to form a cable, and the middle of the cable A filling layer is provided, an outer insulation layer is arranged on the outside of the cable, a shielding layer is arranged on the outside of the outer insulation layer, and an outer sheath is arranged on the outside of the shielding layer.

The above-mentioned filling layer is a fiber material.

The above-mentioned inner insulating layer and outer insulating layer are polyvinyl chloride.

The beneficial effects of the utility model are: simple production, convenient use, light weight, convenient construction, the shielding layer reduces the corona sound and radio interference level of the wire, the filling layer can effectively prevent mutual interference between signals, and improve signal transmission quality.

4. Description of drawings

Accompanying drawing 1 is the structural representation of the utility model;

In the figure above: outer sheath 1, inner insulating layer 2, shielding layer 3, wire core 4, outer insulating layer 5, filling layer 6.

5. Specific implementation

In conjunction with accompanying drawing 1, the utility model is further described:

The utility model comprises an outer sheath 1, an inner insulating layer 2, a shielding layer 3, a wire core 4, an outer insulating layer 5, and a filling layer 6. The inner insulating layer 2 is arranged outside the wire core 4, and multiple sets of wire cores 4 are stranded. To form a cable, a filling layer 6 is provided in the middle of the cable, an outer insulating layer 5 is provided outside the cable, a shielding layer 3 is provided outside the outer insulating layer 5, and an outer sheath 1 is provided outside the shielding layer 3 .

A preferred filling layer 6 is a fibrous material.

The preferred inner insulating layer 2 and outer insulating layer 5 are polyvinyl chloride.

It is easy to make, easy to use, light in weight, and convenient in construction. The shielding layer reduces the corona sound and radio interference level of the wire, and the filling layer can effectively prevent mutual interference between signals and improve signal transmission quality.
