In order to solve the shielding problem of aviation socket to filter this section of power line, way common is at present, making one can the radome of shield electromagnetic interference, this radome is a part of in conjunction with cabinet housing, casing of filter is a part of together forms shielding cavity, thus the power line shielding that will be in wherein, please refer to Fig. 1.
But the distance that the basis that this way can realize is filter and aviation socket itself to be arranged is very near, so can not miscellaneous part be there is between the two, directly a radome is adopted to carry out shielding just passable.But along with technical development, update cabinet inside part, when entirety being carried out miniaturized improvement, more requirements are proposed to interior layout, the mode adopting radome to carry out shielding will hinder design of optimizing distribution, and is not suitable for layout requirements more flexibly.
[summary of the invention]
The utility model proposes a kind of power line screening arrangement of more flexible, applicable overall structure downsizing design for above problem, can by the output of aviation socket to filter input between power line shield, and filter and aviation socket can be applicable to, shield under being in the various situations of different relative position different spacing.
Described in the utility modelly relate to power line screening arrangement, this device comprises shielding cylinder band and cranse, and this shielding cylinder band is flexible knitting band, comprises the cylinder band of different diameters and length, is set in cable outside; And this cranse is for by the wiring insulated column of the end winding support of shielding cylinder band at aviation socket or filter.
This shielding cylinder band adopts insulating material braiding to form, and forms the belt in form of sleeve in the middle of a both ends open.
This cranse comprises cranse body and securing member, securing member active lock lock ring circle body two ends.
This cranse body comprises the stiff end being fixedly mounted with securing member and the movable end being provided with locking button bit, securing member one of them tight locking button position locking cranse body two ends corresponding.
The utility model, by flexible shielding cylinder band and cranse, can coordinate the shell of aviation socket, filter housing jointly to form a shielding cavity, realize function of shielding.And be set up more flexible and reasonable at cabinet inside general layout cloth, be applicable to various different spacing and the arrangement of position spatially.

[embodiment]
Below in conjunction with drawings and Examples, the utility model is described in detail.
If Fig. 1 is traditional screen shielding apparatus, adopt a radome 5 having sticked shielding material 6, be installed in cabinet housing, this radome 5 forms shielding cavity in conjunction with a cabinet 2 housing part, a filter 4 housing part.The power line 3 of aviation socket 1 to this section of filter 4 input can be shielded completely.As Fig. 2.
Please refer to accompanying drawing 3: illustrated therein is and described in the utility modelly relate to power line screening arrangement, this device comprises shielding cylinder band 10 and cranse 20, and this shielding cylinder band 10 is flexible knitting band, comprises the cylinder band of different diameters and length, is set in cable outside; And this cranse 20 is for by the wiring insulated column of the end winding support of shielding cylinder band 10 at aviation socket or filter.
This shielding cylinder band 10 adopts insulating material to weave and forms, and forms the belt in form of sleeve in the middle of a both ends open.
This cranse 20 comprises cranse body 21 and securing member 22, securing member 22 active lock lock ring circle body 21 two ends.
This cranse body comprises the stiff end being fixedly mounted with securing member and the movable end being provided with locking button bit, securing member one of them tight locking button position locking cranse body two ends corresponding.Please refer to accompanying drawing 3, illustrated therein is the structure of cranse 20, cranse two ends, there is the screw thread of M2.5 one end, and one end is provided with locking button bit, and this locking button bit is that several install through hole.The object arranging multiple installation through hole is the difference in size of filter wiring insulated column in order to adapt to different manufacturers and different loads and adapts to the tail diameter of different housings aviation socket, increases the versatility of cranse 20.Such cranse has just possessed the locking mechanism of adjustable aperture thickness.
The copper alloy band of cranse body 21 material selection 0.4 millimeter of cranse 20, benefit is that one is material softer, is easily certainly shaped with in screw-driving process; Another is then be easy to cutting when cranse is long.
By reference to the accompanying drawings 3 and accompanying drawing 4: to this screening arrangement, concrete how to aviation socket and filter, the wiring in cabinet is described, aviation socket 1 is arranged on cabinet 2 wall, positive and negative electrode or power line 3 one end, two, L, N pole are welded on the core of aviation socket 1, and the other end is inserted on the binding post of filter 4 by terminal.
