Abstract

The invention discloses a center-adjustable self-elastic contact finger conducting structure, which comprises a contact finger base and a round tube-shaped contact finger body, wherein the round tube-shaped contact finger body is made of copper materials, a baffle sheet is fixed on the top surface of an upper round table of the contact finger base, an annular insulation sheet sheathed on the upper round table is paved on the annular top surface of the lower round table, and the upper round table is vertically inserted and connected into the contact finger body so that the lower end of the lower contact finger is clamped on the side wall of the upper round table and is butted and pressed on the insulation sheet. The center-adjustable self-elastic contact finger conducting structure adopts the novel self-elastic type contact finger for realizing double-side stress, the advantages of the self-elastic structure are preserved, the universality is good, the center-adjustable performance is realized, the electric field is uniform, simultaneously, the heavy current flowing capability is simultaneously realized, the integral size is not increased, and no complicated springs and contact sheets are adopted. The center-adjustable self-elastic contact finger conducting structure has the characteristics that the structure is simple, the size is small, the use is flexible, the reliability ishigh, the processing is easy, the cost is low, and the like.

Description

But a kind of aligning self-reliance fingertip conductive structure

Technical field

The present invention relates to a kind of for outer conducting structure in the self-reliance of high voltage switchgear.

Background technology

Moving connection conductive structure main in the High-Voltage Electrical Appliances comprises: 1) self-reliance fingertip does not need holddown spring simple in structure, reliable operation, the profile radius of curvature is big, help to relax the electric field in contact gap, but this version is one-sided elastic edge shape, does not possess adjustable disposition.2) plum blossom touch base, it is many to have a good aligning contact point, good conductivity, but volume is big, on compact apparatus, is bottleneck, and there are defectives such as spring failure in complex structure.

Summary of the invention

For solving the problems referred to above that existing conductive structure exists, but the invention provides a kind of aligning self-reliance fingertip conductive structure, its technical scheme of taking is: comprise fingertip base and the cylindrical shape fingertip body of being made by copper product, the roof of fingertip body and diapire are the curved end to the tube inner process, vertically have the slit from the roof to the lower sidewall on the sidewall of fingertip body

, slit

Evenly distribute adjacent two slits in the form of a ring

Between form fingertip on the self-reliance, on the sidewall of fingertip body, vertically have the slit from the diapire to the side wall upper part simultaneously

, slit

Evenly distribute in the form of a ring, and each slit

Between adjacent two slits

The centre position, adjacent two slits

Between form fingertip under the self-reliance, the center of fingertip base has vertical cylindrical cavity, the last round platform diameter of fingertip base is less than round platform diameter under it, make down round platform have annular top surface, the diameter of last round platform is slightly less than the internal diameter of fingertip body, catch is fixedly arranged on the end face of last round platform, have the circular hole that overlaps in the vertical direction with cylindrical cavity on the catch, be laid with the annular insulation film that is enclosed within round platform on the annular top surface of following round platform, last round platform vertically is plugged in the fingertip body, the lower end of fingertip is clipped on the sidewall of round platform, and roof pressure is on insulating trip.

The present invention adopts novel self-reliance fingertip bilateral stressed, makes self-support type structure get advantage and obtains keeping, and versatility is good, possess adjustable disposition, electric field is even, solves big electric current through-current capability simultaneously, do not increase overall volume, therefore do not have complicated spring and contact, have simple in structurely, volume is little, use flexibly, characteristics such as good reliability is easy to processing, and cost is low.

Embodiment

Describe the present invention below in conjunction with the drawings and specific embodiments.

As Fig. 1, Fig. 2 and shown in Figure 3, fingertip body 2 is cylindrical shape, is made by the rubber-like copper product, and the roof of fingertip body 2 and diapire are the curved end to the tube inner process, vertically has the slit from the roof to the lower sidewall on the sidewall of fingertip body 2

3, slit

3 evenly distribute adjacent two slits in the form of a ring

Form fingertip 4 on the self-reliance between 3, on the sidewall of fingertip body 2, vertically have the slit from the diapire to the side wall upper part simultaneously

5, slit

5 evenly distribute in the form of a ring, and each slit

5 between adjacent two slits

3 centre position, adjacent two slits Form fingertip 6 under the self-reliance between 5.The center of fingertip base 1 has vertical cylindrical cavity 7, last round platform 8 diameters of fingertip base 2 are less than round platform 9 diameters under it, make down round platform 9 have annular top surface, the diameter of last round platform 8 is slightly less than the internal diameter of fingertip body 2, catch 15 is fixedly arranged on the end face of last round platform 8, have the circular hole 10 that overlaps in the vertical direction with cylindrical cavity 7 on the catch 15, annular insulation film 14 be enclosed within on the round platform 8 and the annular top surface of the round platform 9 that is laid in down on.Last round platform 8 can vertically be plugged in the fingertip body 2, the lower end of fingertip 6 is clipped on the sidewall of round platform 8, and roof pressure is on insulating trip 14.

As shown in Figure 4, upper conductor 11 is inserted in fingertip body 2 upper ends, and by last fingertip 4 clampings, bolt 12 passes circular hole 10 and cylindrical cavity 7 successively, lower conductor 13 is fixed on the bottom of fingertip base 1, curved end by last fingertip 4 and following fingertip 6 realizes that the transition of upper conductor 11 and lower conductor 13 is connected, and when upper conductor 11 and lower conductor 13 decentraction, the elasticity that has by last fingertip 4 and following fingertip 6, they are regulated voluntarily, guarantee that stressed evenly contact is good, conduction is reliable.
