Shielded type cable is that a kind of cover that adds on bare cable twines the screen that constitutes by woven wire braiding or metallic foil, is specifically designed to the interconnecting cable that suppresses bare cable electromagnetic coupled and electromagnetic emission.This cable and shielding case/rack, the supporting use of shield facility such as shielding shelter/shielded enclosure etc. can effectively improve the shielding properties of electronic equipment and electronic system.
The using method of conventional shielded electric wire be by with shield facility on transfer the shielding under two above shield facility connected condition that realize of electronics/electrical cnnector, but, then can't provide effective shielding for following two kinds of situations:
(1) the switching heart yearn is too much overstocked, and switching heart yearn current/voltage is excessive.Because the restriction of connector manufacturing technology can't be made corresponding connector;
(2) owing to can't know the cable size that runs through shield facility in advance, and opening diameter causes to have the slit between shielded type cable and the shield facility hole greater than cable size on shield facility, reduces its system mask usefulness.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, practical, easy to disassemble and assemble, screening effectiveness height, is applicable to the screening arrangement of non-switching shielded type cable.
The technical solution of the utility model is: a kind of screening arrangement that is applicable to non-switching shielded type cable, it is characterized in that: which comprises at least metal flange 1, finger-type metal spring leaf 2, metal clip 3, metal flange 1 is fixedlyed connected with metal wallboard 6, finger-type metal spring leaf 2 parts evenly distribute and are fixed on the flange hole wall of metal flange 1, another part extends to outside the flange hole, extend on the outer finger-type metal spring leaf 2 of flange hole and be with metal clip 3, finger-type metal spring leaf 2 is wrapped in screen 4 outer surfaces that are with cable 7.
Described finger-type metal spring leaf 2 is hollow cylindrical.
The described screen 4 that is enclosed within cable 7 outer surfaces is double layer screen layers 4, between the two-layer screen 4 insulating barrier 5 is arranged.
Described metal flange 1 is the spliceosome of two semicircle flanges, the finger-type metal spring leaf 2 that matches with it also is the spliceosome of two half-cylindrical finger-type metal spring leafs 2, the spliceosome part of two half-cylindrical finger-type metal spring leafs 2 is evenly distributed on two overhanging lumen pore walls of semicircle flange spliceosome that match, and another part extends to outside the flange hole.
Described metal flange 1 is to be made by steel or copper product, and metal flange 1 surface coverage has zinc coat or chromium coating or nickel coating.
It is that the beryllium-bronze of 0.04mm～0.25mm is made that described finger-type metal spring leaf 2 surface coverage have chromium coating or nickel coating or thickness.
The beneficial effects of the utility model are: owing at cable jacket screen is arranged, the screen outer surface is enclosed with finger-type metal spring leaf 2, finger-type metal spring leaf 2 parts are evenly distributed on the flange hole wall of metal flange 1, another part extends to outside the flange hole, extends on the outer finger-type metal spring leaf 2 of flange hole and is with metal clip 3.Metal flange 1 is fixedlyed connected with metal wallboard 6,
After cable passed the metal wallboard of screening arrangement, finger-type metal spring leaf and screen closely overlapped; Because finger-type metal spring leaf 2 has certain elasticity, and extend on the outer finger-type metal spring leaf 2 of flange hole and be with metal clip 3, with the fastening distortion of finger-type metal spring leaf, 360 ° of conductions of finger-type metal spring leaf 2 and shield layer of shielded cable surface are fixedlyed connected, thereby make shield layer of shielded cable because the electric current of radiation place induction flow to the shield facility surface, and do not flow into shield facility inside, thereby realize the electromagnetic shielding of non-switching shielded type cable when running through shield facility.
