Embodiment
For further understanding invention essence of the present utility model, describe its characteristics in detail below in conjunction with the drawings and specific embodiments.
See figures.1.and.2, the utility model transfiguration bus duct comprises the shell 2 of busbar 1 and sealing and fixing busbar 1.Also comprise variable capacity connector 3, this variable capacity connector 3 comprises fixed insulation plate 31, mobile conductive plate 32 and mobile insulation board 33.Wherein, fixed insulation plate 31 is fixedlyed connected with the shell 2 of transfiguration bus duct, and mobile conductive plate 32 has many groups, and every group of conducting strip that includes the multi-disc layered laminate is fastenedly connected by bolt 37 between each conducting strip.The centre of conducting strip is provided with the through hole of strip, and bolt 37 is promptly fastening with each conducting strip by this through hole.But each organizes the conducting strip slide relative in the mobile conductive plate 32, and in sliding process, can keep good electrical to connect, wherein a conducting strip is connected with busbar 1 by conducting element 34, and be fixed on the fixed insulation plate 31, another conducting strip is fixed on the mobile insulation board 33, and mobile insulation board 33 relative fixed insulation boards 31 or shell 2 are slided.
The utility model adopts said structure, make busbar 1 have extendible equivalent effect, under the situation that does not change shell 2 and busbar 1 length, can make effective length increase of the present utility model and capable of expansion and contraction, thereby can adapt to various construction environments, effectively avoid the long or too short phenomenon of bus duct.
With reference to Fig. 3 and Fig. 4, mobile conductive plate 32 comprises that first conducting strip 35, second conducting strip 36 and cover plate 41, the first conducting strips 35 are smooth laminated structure, and it is fixed on the mobile insulation board 33, and the centre has bar hole 35a; Second conducting strip 36 has the bar hole 36as identical with first conducting strip 35 size, and when first conducting strip 35 and second conducting strip 36 were cross layered, the two bar hole 35a, 36a can overlap.Mobile conductive plate 32 includes many groups, and the number of group is corresponding with the number of busbar 1, is connected fasteningly with bolt 37 in the 36a by being inserted into bar hole 35a between each is organized, and is furnished with packing ring 38 between bolt 37 and the mobile conductive plate 32.On second conducting strip 36, be provided with stair-stepping protuberance 36b with first conducting strip, 35 laminated sections, the height of protuberance 36b is identical with the thickness of first conducting strip 35, like this, first conducting strip 35 and second conducting strip 36 are mutual when stacked, surface after stacked is a tabular surface, makes the two keep well contacting with cover plate 41.
Each is organized a leaf spring 39 all is set between the mobile conductive plate 32, can make between mobile conductive plate 32 and the mobile insulation board 33, move between conduction 32 and the mobile conductive plate 32 and be resiliency supported between first conducting strip 35 and second conducting strip 36, make first conducting strip 35 and second conducting strip 36 remain excellent electric contact.Leaf spring 39 is made for insulating material, or leaf spring 39 is for metal material but set up insulation board 42 between itself and the mobile conductive plate 32.
When variable capacity connector 3 of the present utility model uses, as long as promote mobile insulation board 33, mobile insulation board 33 drives first conducting strip 35 and moves, because second conducting strip 36 is connected with busbar 1, and be fixed on the fixed insulation plate 31, therefore, first conducting strip 35 slides relative second conducting strip 36.Because first conducting strip 35 and second conducting strip, 36 cross layered backs are fastening by bolt 37, when first conducting strip 35 slides, drive bolt 37 and move in bar hole 35a, 36a, move to the end of bar hole 35a, 36a up to bolt 37.First conducting strip 35 promptly is connected with busbar 1 by second conducting strip 36, therefore, only need on first conducting strip 35 to set up splicing ear, the terminal group that is formed by first conducting strip 35 can form a distribution branch road, thereby prolonged the effective length of bus duct, made bus duct become the variable capacity bus duct.
For further increasing the effective length of bus duct, the mobile conductive plate 32 of variable capacity connector 3 also comprises prolongation conducting strip 40, and it is between first conducting strip 35 and second conducting strip 36, and the centre has the fixing hole 40a of bar shaped.Like this, can misplace the relatively distance in three strip holes of first conducting strip 35 and second conducting strip 36, it is comparatively obvious to prolong effect.
In sum, transfiguration bus duct of the present utility model moves conductive plate 32 connected modes because of the dislocation slidingtype that adopts retractable, only needs to promote mobile insulation board 33, the effective length that can prolong the transfiguration bus duct, and extending length can freely be selected.After splicing ear was installed on first conducting strip 35, the length that not only can prolong bus duct also can be used as a distribution branch road of bus duct, to satisfy different user, without the demand of construction environment.And easy to use, reliable, also can be used as the common standard bus duct and use.
The above only is a preferred embodiment of the present utility model; be not so limit its claim; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to be done; directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
