Embodiment
The technical solution of the utility model is further illustrated by embodiment below in conjunction with accompanying drawing.
The technical problem solved for making the utility model, the technical scheme of employing and the technique effect that reaches are clearly, be described in further detail below in conjunction with the technical scheme of accompanying drawing to the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those skilled in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Fig. 1 and Fig. 2 is stereogram and the structural representation of a kind of rack wiring casing that present embodiment provides respectively.As depicted in figs. 1 and 2, a kind of rack wiring casing that present embodiment provides comprises trough 1 and cover plate 2, cover plate 2 and trough 1 clamping, rack wiring casing with can the cabinet shell of ground connection be fixedly connected with.
This rack wiring casing is fixedly connected with the cabinet shell of ground connection; wiring casing is not only made to have good shield effectiveness; efficiently solve the problem of crosstalk between various cables that existing rack cabling mode exists; improve the EMC characteristic of Internal cable; shorten EMC test period, and serve good mechanical protection and electic protection effect.Meanwhile, the structure be connected by screw fastening with cover plate and the trough of existing wiring casing is compared, clamping between the cover plate 2 of rack wiring casing and trough 1, and structure is more simple, easy to process, and convenient disassembly is convenient to maintenance.
In the present embodiment, propose a kind of preferred rack wiring casing, this wiring casing comprises trough 1 and cover plate 2, cover plate 2 and trough 1 clamping, rack wiring casing with can the cabinet shell of ground connection be fixedly connected with.Concrete, trough 1 comprises base plate 11 and perpendicular to base plate 11 and be oppositely arranged two side plates 12, two side plates 12 and cover plate 2 clamping.Concrete, side plate 12 arranges card convex, and cover plate 2 arranges the draw-in groove corresponding with card convex, and card convex and draw-in groove closely cooperate, and realize the clamping of side plate 12 and cover plate 2.Can also be, side plate 12 arranges draw-in groove, cover plate 2 arranges the card convex corresponding with draw-in groove, realize the clamping of side plate 12 and cover plate 2 equally.
Two side plates 12 are not limited to above-mentioned card convex and draw-in groove fit structure with the interface arrangment of cover plate 2, can also be that side plate 12 and cover plate 2 arrange the hasp cooperatively interacted respectively, and side plate 12 coordinates the overlap joint of hasp to realize being connected with cover plate 2 by two.
In order to save space, the convenient cable arranging different types, the medial surface of base plate 11 is provided with some dividing plates 13 be parallel to each other along its length, so, whole rack wiring casing can be separated into different little wiring casings, and the cable of number of different types can be fixed in different little wiring casings.
