An adjustable center self-supporting contact conduction structure

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

technical field

[0001] The invention relates to a self-supporting internal and external conductive structure for high-voltage switchgear. Background technique

[0002] The main dynamic connection conductive structures in high-voltage electrical appliances include: 1) Self-supporting contact fingers, no need to compress the spring. Side elastic sides, not adjustable. 2) The plum blossom contact seat has good self-alignment, many contact points, and good conductivity, but it is large in size, which is a bottleneck in miniaturized equipment, complex in structure, and has defects such as spring failure. Contents of the invention

[0003] In order to solve the above-mentioned problems existing in the existing conductive structure, the present invention provides an adjustable self-supporting contact conductive structure. Finger body, the top wall and bottom wall of the finger body are arc-shaped end faces protruding into the cylinder, and a long slit is vertically opened on t...
