As further improvement of the utility model:
Be equipped with pad on the both ends of the surface of described movable contact spring, described pad is sheathed on the rotating shaft, and the end face of described pad is attached on the end face of movable contact spring.
Described fingertip support is provided with guide vane end stop, and described guide vane end stop is positioned at the spacing draw-in groove on the moving contact rack.
Compared with prior art, advantage of the present utility model just is:
1, the utility model is simple and compact for structure, with low cost, will rotate and conduction combines, and stable drive, electric conductivity is good;
2, the transmission contact point is many in the structure of the present utility model, and what of contact point are the through-current capability size generally depend on, this structure can guarantee to be provided with contact point as much as possible, and a plurality of contact point has guaranteed the transmittability of big electric current; The fingertip of the utility model structure is installed in the fingertip support, and with the axle center circle distribution of rotating shaft, can be designed to difference according to size of current different distributions quantity, therefore can guarantee contact point as much as possible.
3, contact pressure is constant in the structure of the present utility model.Contact pressure determines the through-current capability size equally, and the contact force value that the fingertip spring provides has guaranteed every through-current capability unanimity, solves the local pyrexia defect that existing GIS equipment conductive structure causes because of contact force value difference;
4, structure radiating condition of the present utility model is good.The fingertip support has adopted the cast bronze material, and grating structure design, and be provided with louvre is for the transmission of big electric current provides good radiating condition.

Embodiment
Below with reference to specific embodiment and Figure of description the utility model is described in further details.
As Fig. 1, Fig. 2 and shown in Figure 3, a kind of electric installation that is used between the Cubicle Gas-Insulated Switchgear rotary body of the utility model, it comprises movable contact spring 1, U-shaped moving contact rack 2, more than one fingertip 3, more than one fingertip spring 5 and two fingertip supports 8, fingertip 3 and fingertip spring 5 all adopt 54 in the present embodiment, to satisfy the needs that big electric current passes through.Offer installing hole 9 on the moving contact rack 2, one end of movable contact spring 1 is fixed in the U-shaped opening part of moving contact rack 2 by being installed in rotating shafts 7 in the installing hole 9, movable contact spring 1 connects with rotating shaft 7 rectangular splines commonly used, and movable contact spring 1 both ends of the surface are concordant with the spline end face of rotating shaft 7.Be equipped with pad 6 on the both ends of the surface of movable contact spring 1, pad 6 is sheathed on the rotating shaft 7, and the end face of pad 6 is attached on the end face of movable contact spring 1.Two fingertip supports 8 lay respectively at the two ends of movable contact spring 1, and the inner hole sleeve of fingertip support 8 is located on the rotating shaft 7, and the cylindrical of fingertip support 8 is positioned at installing hole 9.Referring to Fig. 4, fingertip support 8 is provided with the guide vane end stop 11 that is convex, and guide vane end stop 11 is positioned at the spacing draw-in groove 13 on the moving contact rack 2.One end face of fingertip support 8 contacts with pad 6, and the other end contacts with back-up ring 4, and back-up ring 4 is installed in the circlip groove of moving contact rack 2.Fingertip support 8 is in positioning states completely thus.Offer an above fingertip installing hole 10 and fingertip spring mounting hole 12 on the fingertip support 8, fingertip spring 5 is installed in the fingertip spring mounting hole 12, one end of fingertip 3 is positioned at fingertip installing hole 10 and contacts with fingertip spring 5, in the cavity that the other end forms between fingertip support 8, U-shaped moving contact rack 2 and movable contact spring 1, be that one end contacts with an end face of fingertip spring 5, a disc on the other end contacts with the disc of moving contact rack 2 is tangent, and another disc contacts with the plane of movable contact spring 1 is tangent.Because fingertip support 8, back-up ring 4, fingertip spring 5, fingertip 3 all are to install in the two sides of movable contact spring 1 symmetry, adopt the flexible force value contact of fingertip spring 5 simultaneously, so movable contact spring 1 are positioned the center position of U-shaped opening on the moving contact rack 2.
When needs rotated, outside torsional moment acted on rotating shaft 7, and rotating shaft 7 rotates, and drove movable contact spring 1 by splined and rotated with respect to moving contact rack 2.Referring to Fig. 2, the direction of arrow and sign A are the transmission direction of electric current among the figure.When conducting electricity, after electric current flows into from movable contact spring 1 direction, electric current flows into the fingertip 3 that contacts with it by fingertip spring 5 constant force from two planes of movable contact spring 1, continue to flow into the moving contact rack 2 that contacts with it by fingertip spring 5 constant force equally by fingertip 3, the other end from moving contact rack 2 flows out again.Finished like this that two electric conductors rotate mutually and can be by the process of electric current.
