Abstract
A special shielding signal cable belongs to the field of cable technology, which comprises a cable core comprising cores and a shielding and a sheath on the cable core, is characterized in that the core comprises a conductor sequentially provided with an insulating layer, a tin plating copper braided shielding layer and an elastomer high flame-proof small smoke and low halogen polychloroethylene sheath and a flame-proof polyester isolation strip sequentially provided with the tin plating copper braided shielding layer and the sheath is arranged on the cable core. The utility model has reasonable and simple structure, easy production and manufacture, shielding layers arranged on the wires and the cable cores, good dually shielded effect, accurate signal transmission and stability and reliability. The tin plating copper braided layer used as the shielding layer not only has good shielding effect, low coupled electromagnetism and reactance between the adjacent cores in the cables and strong personalized signal transmission, but also is easy to bend, has good pliability and is applicable for all the signal equipments of stronger shielding location, electronic and power-network apparatus and automated assembly.
Description
Technical field
The utility model relates to a kind of structure of signal shielding cable, belongs to the cable technology field.
Background technology
Existing signal shielding cable is made of cable core, screen, sheath etc. usually, and the material that screen uses adopts aluminium strip, copper wire, copper strips, shielding layer structure is to screen and total screen, in the cable between adjacent core lotus root close electromagnetism and reactance is all higher, personalized signals transmission performance difference and cable to deflect performance not strong, can not satisfy some has the dried requirement of scratching and the used cable of engineering in the personalized signals transmission region being arranged of forceful electric power magnetic.
The utility model content
The purpose of this utility model is exactly for satisfying the needs in market, a kind of stable signal transmission is provided, the extraordinary signal shielding cable that pliability is good.
The purpose of this utility model is to realize like this, extraordinary signal shielding cable, comprise cable core and screen on the cable core and the sheath made by core, it is characterized in that constituting of described core by setting gradually insulating barrier, tinned copper wire woven shield and elastomer high fire retarding low-smoke low-halogen polyvinyl chloride sheath on the conductor, described cable core is provided with the fire-retardant polyester isolation strip, sets gradually tinned copper wire woven shield and sheath on the isolation strip.
Described insulating barrier is the polyethylene insulation material layer.Sheath is an elastomer high fire retarding low-smoke low-halogen polyvinyl chloride cover.
The utility model is rational in infrastructure simple, manufactures easily, and phase line and cable core are equipped with screen, and dual shield is effective, and the signal transmission accurately, and is reliable and stable.With the tincopper fuse wire braided armor is screen, not only shield effectiveness is good, in the cable between adjacent core lotus root close electromagnetism and reactance is all lower, the personalized signals transmission performance is strong, also have flexible, the flexible performance is good, is applicable to the various signalling arrangements of higher shielding occasion, and electronics, grid equipment and automation equipment use.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure: 1 conductor, 2 insulating barriers, 3 screens, 4 sheaths, 5 isolation strip, 6 screens, 7 sheaths.
Embodiment
With the tinned copper wire twisted bundles is conductor 1, extrudes polyethylene insulating barrier 2 on conductor 1, and braiding tinned copper wire woven shield 3 on insulating barrier 2 extrudes the low halogen polyvinyl chloride sheath 4 of elasticity high flame resistance, low smoke and makes core on screen 3.Wrapped fire-retardant polyester isolation strip 5 on the cable core with many core strandings, 5 braiding tinned copper wire woven shields 6 extrude elastomer high fire retarding low-smoke low-halogen polyvinyl chloride sheath 7 on screen 6 in the isolation strip.
Claims (3)
