Description
Technical field
The invention belongs to electronics/electrical equipment interconnect shield technical field, particularly a kind of screening arrangement and method for designing thereof that is applicable to non-switching shielded type cable.
Background technology
Shielded type cable is that a kind of cover that on bare cable, adds 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 method for using of conventional shielded electric wire be through with shield facility on the shielding under two above shield facility connected condition that realize of transferring of electronics/electrical cnnector, but, then effective shielding can't be provided for following two kinds of situation:
(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 object of the present invention is to provide the screening arrangement that a kind of simple in structure, practical, easy to disassemble and assemble, screening effectiveness are high, be applicable to non-switching shielded type cable.
Technical scheme of the present invention is: a kind of screening arrangement and method for designing thereof 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 fixedly connected with metal wallboard 6; One end of finger-type metal spring leaf 2 and the flange hole matching and fixing of metal flange 1, finger-type metal spring leaf 2 are wrapped in screen 4 outer surfaces that are with cable 7.
Described finger-type metal spring leaf 2 parts that are wrapped in screen 4 outer surfaces are evenly distributed on the flange hole wall of metal flange 1, and another part extends to outside the flange hole, extend on the outer finger-type metal spring leaf 2 of flange hole and are with metal clip 3.
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 processed 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 processed that described finger-type metal spring leaf 2 surface coverage have chromium coating or nickel coating or thickness.
The invention has the beneficial effects as follows: owing to screen is arranged at cable jacket; 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 fixedly 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 fixedly 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.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Fig. 1 is an embodiment screening arrangement shielding construction sketch map;
Fig. 2 is the structural representation of the embodiment of the invention.
Among the figure: 1, metal flange; 2, finger-type metal spring leaf; 3, metal clip; 4, screen; 5, insulating barrier; 6, metal wallboard; 7, cable; 8, installing hole; 9, stationary plane.
Embodiment
The present invention is not limited only to this.Said finger-type metal spring leaf 2 can be hollow cylindrical.
The described screen 4 that is enclosed within cable 7 outer surfaces can be a double layer screen layer 4, has insulating barrier 5 as shown in Figure 1 between the two-layer screen 4.
Described metal flange 1 is to be processed by steel or copper product, and metal flange 1 surface coverage has zinc coat or chromium coating or nickel coating.
