Abstract
The utility model relates to an anti-electromagnetic interference shielded cable, comprising insulation cores formed by extruding internal conductors with insulating layers; the two insulation cores are intertwisted and successively covered with a shielding layer and an extruding sheath. The beneficial effects of the utility model are that: 1. the filtering effect is good: the two insulation cores are completely covered with an electromagnetic shielding membrane to take better effects for filtering; 2. the processing is convenient: the filtering shielding layer is covered to simplify the process of adding filtering rings and to raise the production efficiency.
Description
Technical field
The utility model relates to the anti-electromagnetic interference shielding cable that fields such as a kind of communication, electronics are used for the signal transmission.
Background technology
Along with the develop rapidly of communication and electronics, to the higher electromagnetic compatibility requirement of cable proposition of signal transmission usefulness.Traditional cable in order to eliminate the influence of high order harmonic component to signal and complete machine, is generally overlapped the filtering ring of a Ferrite Material outside cable in the cable course of processing when the transmission electromagnetic wave, this filtering ring mainly plays filter action.Increase the processing technology more complicated of filtering ring, and the general length of inferior filtering ring can not play the effect of complete filtering than weak point.
Summary of the invention
In view of the deficiency that prior art exists, the utility model provides a kind of anti-electromagnetic interference shielding cable.
The utility model is for realizing above-mentioned purpose; The technical scheme that is adopted is: a kind of anti-electromagnetic interference shielding cable; The insulated wire cores that the outer extruded insulation layer of the conductor that included constitutes is characterized in that: two stranded backs of said insulated wire cores outside it successively lapped shielding layer, extrude sheath.
The beneficial effect of the utility model is: 1, good wave filtering effect: adopt the wrapped on two insulated cores of electromagnetic shielding film 100%, play better filter effect.2, easy to process: as to adopt wrapped filtering screen to simplify the processing technology that adds the filtering ring, improved production efficiency.
