Embodiment Construction

[0011] see figure 1 As shown, the cable 10 of the present invention is circular, which includes a plurality of conductors 11, insulators 12, aluminum foil layers 13, aluminum foil Mylar layers 14, braided layers 15, protective layers 16 and outer layers wrapped around the conductors 11 from inside to outside. Cover layer 17.

[0012] The conductor 11 includes a power conductor 111 and several pairs of differential signal conductors 112 , each conductor 111 , 112 is wrapped with an insulator 12 , and each pair of differential signal conductors 112 is wrapped with a common layer of aluminum foil 13 . In other embodiments, the conductor 11 includes a ground conductor.

[0013] see figure 2 As shown, the protective layer 16 is located between the braiding layer 15 and the outer layer 17, and is used to improve the overall EMC (electromagnetic compatibility) performance of the cable 10, so that the entire cable 10 has EMC performance from the beginning to the end. The protectiv...

Abstract

The invention relates to a cable. The cable comprises at least one conductor, as well as insulators, a protective layer and an outer wrapping layer which wrap the peripheries of the conductors sequentially; the protective layer comprises a magnetic medium, an adhesive and a Mylar layer; the magnetic medium is adhered on the surface of the Mylar layer by means of the adhesive; and therefore, the EMC performance of the whole cable can be improved, and the cable has excellent EMC performance from the head to the tail.

Description

technical field [0001] The invention relates to a cable. Background technique [0002] EMC (Electro Magnetic Compatibility, Electromagnetic Compatibility) is defined as "the ability of equipment and systems to work normally in their electromagnetic environment without causing unacceptable electromagnetic disturbance to anything in the environment". This definition contains two meanings. First, , the device should be able to work normally in a certain electromagnetic environment, that is, the device should have a certain electromagnetic immunity (EMS); secondly, the electromagnetic disturbance generated by the device itself should not have an excessive impact on other electronic products, that is, Electromagnetic Interference (EMI). [0003] In order to solve the EMC performance of the equipment, the traditional solution is to install a shielding magnetic ring on the cable. The shielding magnetic ring is generally set at the head or tail of the cable, that is, to shield the ...
