Abstract
An isolating switch contact composes a contacting arm, a contacting head spring plate, a fixed bar, and a pair of styli. The utility model is characterized in that the stylus is a sheet form square disk shaped structure, of which the center is provided with a hole. Two contacts are arranged on both sides of the hole center on the disk bottom. The pair of styli, which are in mirror symmetry, are compressed onto the contacting arm by the fixed bar, which penetrates through the hole, through the contacting head spring plate. By Adopting impact molding, the working procedure of the utility model is reduced well as the productivity is promoted, and by changing the original copper block into copper sheet, the cost of the utility model is decreased. The electrical discharge problem of the edges and corners in the former machining is solved, and the electrical performance is improved, the operation safety of the electrical equipment is promoted as well.
Description
One, technical field
The utility model belongs to the equipment for power transmission and distribution field, particularly a kind of isolation switch contact.
Two, background technology
Isolating switch of the prior art generally adopts copper billet through casting, forges or mills, and digs, and process technologies such as mill and silver-plated processing are made.Manufacturing procedure is many, and production efficiency is low, and the error that each operation accumulation back produces is bigger, and precision is wayward.The fastener portion branch that assembles on the switch exposes, and the switch corner angle of machining are more, have the defective of point discharge, thereby influences electric property; Existing switch contact point surface area is little, and it is bad to dispel the heat.
Three, summary of the invention
At the problems referred to above, the utility model provides a kind of employing stamping forming isolation switch contact, has improved electric property.
Technical solution of the present utility model is: a kind of isolation switch contact, comprise contact arm, touch spring plate, fixed lever and a pair of fingertip, fingertip is sheet side's disc structure, the center is provided with the hole, the heart both sides, hole of dish bottom surface are provided with two contacts, fixed lever passes the hole, respectively a pair of fingertip of mirror image symmetry is pressed on the contact arm by the touch spring plate.
The utility model is the sheet dish, therefore can adopt punch forming, and operation is few, has improved production efficiency, and changing original copper billet is the copper sheet manufacturing, has reduced cost.The corner angle discharge problem that has produced when having solved original machining has been improved electric property, improves the security of operation of electric equipment.
Four, description of drawings
Fig. 1 is the structural representation of isolation switch contact.(1) contact arm, (2) touch spring plate, (3) fixed lever, (4) fingertip among the figure;
Fig. 2 is three multi pack vertical views of isolation switch contact.
Five, embodiment
A kind of isolation switch contact, comprise contact arm 1, touch spring plate 2, fixed lever 3 and a pair of fingertip 4, fingertip 4 is sheet side's disc structure, the center is provided with the hole, the dish bottom surface be provided with two with wide parallel, with the groove shaped contact of Kong Xinwei symmetric points, fixed lever 3 passes the hole, is connected on the contact arm 1 by a pair of fingertip 4 of touch spring plate 2 with the mirror image symmetry.Regulate the degree of tightness of 4 of touch spring plate 2 and fingertips by the nut on the fixed lever.Adopt the cold punching mould pressing technology to the processing of electrolysis oxygen-free copper sheet material, the detail sanding polishing is through silver-plated processing.Can increase and decrease the fingertip sheet logarithm of isolation switch contact according to the size of loop current.
Claims (2)
1. isolation switch contact, comprise contact arm (1), touch spring plate (2), fixed lever (3) and a pair of fingertip (4), it is characterized in that fingertip (4) is sheet side's disc structure, the center is provided with the hole, the heart both sides, hole of dish bottom surface are provided with two contacts, fixed lever (3) passes the hole, respectively a pair of fingertip (4) of mirror image symmetry is pressed on the contact arm (1) by touch spring plate (2).
2. isolation switch contact as claimed in claim 1 is characterized in that fingertip (4) material therefor is silver-plated electrolysis no-oxygen copper plate.
