Abstract
The utility model relates to a super-shielding low-loss signal transmission cable for an encoder, which comprises a core wire assembly formed by twisting a plurality of core wires; each core wire comprises two wire cores formed by conductors and insulating layers, as well as a pair twist covering belt layer and a pair twist shielding layer which are arranged outside the two wire cores; a cable forming covering belt layer is arranged outside the core wire assembly; a general shielding layer is arranged outside the cable forming covering belt layer; and a jacket layer is arranged outside the general shielding layer. As the pair twist shielding layers and the general shielding layer are arranged, the whole cable is good in shielding performance and is not easily interfered. When being in use, the super-shielding low-loss signal transmission cable for the encoder is less in signal transmission loss.
Description
Technical field
The utility model relates to a kind of power transmission cable, relates in particular to a kind of encoder with ultra shielding low-loss signal-transmitting cable.
Background technology
Along with the continuous progress and the development of China's suitability for industrialized production, the range of application of encoder also more and more widely, and is and also very wide as the market prospects of the cable of encoder auxiliary products.
Existing encoder is used cable, and shielding is not high, receive the interference of current signal easily, and signal transmission attenuation is bigger.
The utility model content
To the problems referred to above, the purpose of the utility model is to provide a kind of encoder with ultra shielding low-loss signal-transmitting cable, to solve problems of the prior art.
To achieve these goals, the technical scheme of the utility model is following:
Encoder is with ultra shielding low-loss signal-transmitting cable; It is characterized in that; Comprise the heart yearn assembly that is twisted together by some heart yearns, every heart yearn comprises two cores of being made up of conductor and insulating barrier and is arranged on two cores outer pair twist belting layer and pair twist screen that said heart yearn assembly is outside equipped with the stranding belting layer; Said stranding belting layer is outside equipped with total screen, and said total screen is outside equipped with restrictive coating.
In a preferred embodiment of the utility model, said restrictive coating is the silicone rubber jacket layer.
In a preferred embodiment of the utility model, the gap location between said stranding belting layer and the heart yearn assembly is provided with filler.
In a preferred embodiment of the utility model, said insulating barrier is a polyolefin insulation layer.
The utility model makes that through pair twist screen and total screen are set whole cable shield property is good, does not allow to be subject to disturb.In use, the utility model signal transmission attenuation is less.
Description of drawings
Specify the utility model below in conjunction with accompanying drawing and embodiment:
Fig. 1 is the structural representation of the utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1; Encoder is with ultra shielding low-loss signal-transmitting cable; Comprise the heart yearn assembly that is twisted together by some heart yearns, every heart yearn comprises two cores of being made up of conductor 1 and insulating barrier 2 and is arranged on two cores pair twist belting layer 3 and pair twist screen 4 outward.Insulating barrier 2 is a polyolefin insulation layer.
The heart yearn assembly is outside equipped with stranding belting layer 6, and the gap location between stranding belting layer and the heart yearn assembly is provided with filler 5, and filler 5 can be selected the glass rope for use.
Stranding belting layer 6 is outside equipped with total screen 7, and the utility model makes that through pair twist screen and total screen are set whole cable shield property is good, does not allow to be subject to disturb.
Total screen 7 is outside equipped with restrictive coating 8.Restrictive coating is the silicone rubber jacket layer, can strengthen ageing resistance.
In use, the utility model signal transmission attenuation is less.
More than show and described the advantage of basic principle, principal character and the utility model of the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The just principle of describing in the foregoing description and the specification of the utility model; The utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these variations and improvement all fall in the scope of the utility model that requires protection.The protection range that the utility model requires is defined by appending claims and equivalent thereof.
