Background technology
China's economic growth continuously and healthily, for cable products provides the huge market space, along with the continuous expansion of the industry sizes such as China electric power industry, data communication industry, urban track traffic industry, car industry and shipbuilding, also will increase rapidly the demand of electric wire, following electric wire industry also has huge development potentiality.
In radio art, a lot of occasion all needs to use cable transmission signal, but cable is receiving external electromagnetic
During interference, can transmit signal be had an impact, so electromagnetic shielding process must be carried out to cable.Existing shielded type cable is outside the insulating barrier of cable, arrange metal wire knitted or wrapped one deck screen, thus reduces the current interference in outer bound pair cable insulation, and the current induced magnetic field impact also reduced in cable insulation is extraneous; This cable is using proof copper-wire braided or the copper strips screen as cable, and comparatively large to the loss of copper material, cost is higher; On the other hand, this cable can not shield electromagnetic interference completely, and anti-electromagnetic interference capability is poor.
Summary of the invention
The purpose of this utility model is, overcomes the deficiencies in the prior art, provides a kind of shielded type cable, improves the anti-electromagnetic interference capability of cable, solves the problem of existing cable poor anti jamming capability in background technology.
For solving the problems of the technologies described above, the technical solution of the utility model is: provide a kind of shielded type cable, comprise conductor group, be wrapped in the insulating barrier of described conductor group outside, be wrapped in the screen of described insulating barrier outside and be wrapped in the protective sleeve of described screen outside, described conductor group comprises at least one wire, also comprise channelizing line, described channelizing line is positioned at described screen and in electrical contact with described screen, described insulating barrier and described channelizing line are not in contact with each other, and the space between described insulating barrier and described channelizing line is provided with filler; Described screen is metal net layer or Copper-Aluminum compound strap layer.
Preferably, in above-mentioned shielded type cable, described wire netting is iron net.
Preferably, in above-mentioned shielded type cable, described wire netting is golden net or silver-colored net.
Preferably, in above-mentioned shielded type cable, the quantity of described channelizing line is at least 1, is uniformly distributed in described screen.
Preferably, in above-mentioned shielded type cable, described filler is asbestos filler.
The beneficial effects of the utility model are: the utility model provides a kind of shielded type cable, comprise conductor group, be wrapped in the insulating barrier of described conductor group outside, be wrapped in the screen of described insulating barrier outside and be wrapped in the protective sleeve of described screen outside, described conductor group comprises at least one wire, also comprise channelizing line, described channelizing line is positioned at described screen and in electrical contact with described screen, described insulating barrier and described channelizing line are not in contact with each other, and the space between described insulating barrier and described channelizing line is provided with filler; Described screen is metal net layer or Copper-Aluminum compound strap layer.Screen of the present utility model adopts metal net layer, by wire netting electromagnetic wave absorption, imports underground by channelizing line, thus improves electromagnetic interference capability; Or adopt Copper-Aluminum compound metal tape, reduce copper material loss, reduce costs; Further, between the insulated wire of channelizing line and conductor group, filler is set, better prevents electromagnetic wave on the impact of conductor group.
