Description
Technical field
The utility model relates to a kind of wiring groove and cover board arrangement, especially a kind of be applicable to electrotechnical apparatus field have reliable electric connect wiring groove and cover plate.
Background technology
Existing wiring groove and cover plate are generally made of metal, and comprise wiring groove body and cover plate two parts formation.Guide rail is provided with for installing cable in wiring groove.Cover plate and detachable with wiring groove, is beneficial to installation and the maintenance of cable.Because wiring groove and cover plate are separable, in actual use, both often form contact gap, or both contact positions form a gap band due to the pollutant such as dust, greasy dirt.Following problem may be caused thus:
First the space owing to being formed between cover plate and wiring groove body may cause water, corrosive gas and other pollutants to enter in wiring groove, particularly in the place of bad working environments, these erosions are formed the cable in wiring groove and corrode, destroy cable insulation layer and affect its life-span, even cause short circuit.Wiring groove is so just made to lose its protective effect to Internal cable.
Secondly, because wiring groove and cover plate are made of metal, if it is better airtight, wiring groove contacts with cover plate and forms conductive path, the wiring groove covering cover plate so just forms a metallic cavity, effectively can shield outside electromagnetic interference, the electromagnetic interference between the cable that simultaneously also can alleviate its inside, prevents electrostatic.But due between cover plate and wiring groove body because manufacture craft or pollutant cause can not good contact, form gap.Now wiring groove just can not form conductive path and prevent electrostatic to shield interference.
Moreover the wiring groove of metal structure and cover plate can also pass through ground connection, eliminate electromagnetic interference and prevent Internal cable from leaking electricity, thus guarantee the fail safe of wiring groove while improving antijamming capability.And once produce space between cover plate and wiring groove or have other insulation pollutants to fill, then can not play such effect.
Be necessary to provide one that wiring groove can be made to contact well with cover plate for this reason, and guarantee the wiring groove and the cover board arrangement that form electrical communication between the two.
Utility model content
The purpose of this utility model is consider the problems referred to above and provide a kind of guarantee wiring groove and cover board arrangement that wiring groove and cover plate form electrical communication between the two.
In order to achieve the above object, the utility model is achieved in that provides a kind of wiring groove and cover board arrangement, is made up of wiring groove and cover plate, described cover plate and wiring groove being respectively equipped with draw-in groove, between two draw-in grooves, realizing electromotive force equipotential by connecting with the wire of terminal.
Another object of the present utility model is to provide a kind of wiring groove that makes to contact good wiring groove and cover board arrangement with cover plate.
In order to achieve the above object, the utility model is achieved in that buckle cover plate and wiring groove be respectively equipped with for fastening, and both can be made closely to fasten.Also sealing strip is provided with between cover plate and wiring groove.
Wiring groove is provided with standard rail, and described standard rail is provided with earth terminal and is connected with ground connection main line.
The beneficial effects of the utility model are: be provided with wire casing of the present invention and cover plate realizes wire casing by the draw-in groove above it and cover plate is electrically connected and ground connection reliably; Wire casing is made and cover plate entirety is dust-proof, water resistance good by sealing strip.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
First refer to Fig. 1, Fig. 1 is the structural representation of the utility model embodiment.As shown in Figure 1, this wiring groove and cover board arrangement are made up of known cover plate and wiring groove two parts.In the embodiment in figure 1, cover plate is provided with draw-in groove 1, and this draw-in groove is arranged on below cover plate, and draw-in groove 1 also can be directly one-body molded or be welded in below cover plate in a further embodiment certainly.The outside of cover plate both sides of the edge is provided with the buckle 5 of protrusion, and recessed buckle 5 phase be provided with relative to the inner side of cover plate with wiring groove closely fastens.
Fasten contact site with wiring groove relative to its inner side outside cover plate and be also provided with sealing strip 4, sealing bar can be have flexible rubber or plastic ring.In embodiment in FIG sealing strip 4 be pad at the fastening place of buckle 5, also can be placed in other at other embodiment sealing strips 4 can the position of contact site between seal cover board and wiring groove.
In FIG, be provided with the draw-in groove 1 corresponding with on cover plate bottom wiring groove, draw-in groove 1 is located at the bottom of wiring groove in the present embodiment, and draw-in groove 1 also can the direct one-body molded or optional position that is welded in wiring groove in a further embodiment certainly.Draw-in groove 1 in wiring groove realizes electromotive force equipotential with the draw-in groove 1 below cover plate by being connected with the wire 3 of terminal.
As being provided with standard rail 2 bottom the embodiment wiring groove in Fig. 1, can accomplish again to be reliably connected with ground connection main line by the ground wire terminal on wire casing standard rail 2.On earth terminal on the terminal that ground wire can be connected to the draw-in groove 1 in wiring groove or on the standard rail being separately located in wiring groove.Make by such structure the electrical communication that between wire casing and cover plate, formation one is effective, reliable, intact, realize wire casing and the overall dustproof and waterproof of cover plate by sealing strip.
Wiring groove in above-described embodiment and cover plate are that metal or other electric conducting materials are made.
Those skilled in that art also can do other distortion in creation spirit of the present utility model, and according to creation spirit of the present utility model, derivative various distortion must belong within protection range of the present utility model for these.
