Abstract
The utility model relates to a high-voltage isolating switch, which comprises an external-compression contact terminal mechanism, contact fingers and a contact finger seat, wherein the contact fingers are fixedly connected with the contact finger seat. The high-voltage isolating switch is simple in structure, the contact fingers and the contact finger seat are fixedly connected, thereby guaranteeing conductive transferring, a spring adjusts range interval between two lateral walls of a U-shaped contact finger groove, thereby guaranteeing fine contact with the contact terminal. Further, the utility model is simple and compact in structure, and simultaneously resolves the problem of spring shunt completely in work.
Description
One, technical field:
The utility model relates to high voltage isolator.
Two, prospect technology:
The contact mechanism of high voltage isolator mainly is that conduction reached conducting rod by contact by fingertip, fingertip seat after isolating switch closed a floodgate.Contact mechanism as shown in Figure 1 at present, contact and fingertip deciliter are realized branch, the combined floodgate of isolating switch, do not have between fingertip and the fingertip seat and fixedly connected, and are generally the fingertip internal face and lean on the draw-in groove connection, for avoiding connecting by extension spring between the loosening fingertip, to guarantee that fingertip contacts with contact.When isolating switch branch, closing operation, easily produce the gap between contact-making surface or have dust to exist, the harm one that brings is to cause contact-making surface discharge scaling loss, the 2nd, contact-making surface resistance is during greater than spring resistance, spring is easily shunted, work long hours and easily cause spring heating distortion, damage, directly influence the switch serviceability, cause the accident.
Three, summary of the invention:
The purpose of this utility model is to overcome above-mentioned not enough problem, and a kind of external-compression type contact mechanism is provided, and is simple in structure, compact, and no distributary phenomenon takes place.
The technical scheme that the utility model is adopted for achieving the above object is: the external-compression type contact mechanism, fingertip is fixedlyed connected with the fingertip seat.
Described fingertip is the U type fingertip of phosphor bronze material, and the fingertip seat connects by screw with U type fingertip.
Between the described U type fingertip two side arms compression spring is housed.
Described fingertip seat outside wall surface is equipped with protective cover.
The utility model is simple in structure, and fingertip and fingertip seat are fixedly connected, and guarantees the conduction transmission, spring is regulated the spacing between the U type fingertip groove two side, guarantees to contact with the good of contact, and is simple in structure, in the time of compact, thoroughly solve the spring distributary phenomenon in the work and take place.
Four, description of drawings:
Fig. 1 is traditional structure of contact terminal schematic diagram.
Fig. 2 is the utility model structure of contact terminal schematic diagram.
Five, embodiment:
External-compression type contact mechanism as shown in Figure 2, fingertip are U type fingertip, and the fingertip seat is fixedly connected by bolt and the fingertip side that is positioned at fingertip seat outer wall, between the U type fingertip two side arms compression spring is housed, and fingertip seat outside wall surface is equipped with protective cover 5.
During work, the back contact that closes a floodgate is connected with fingertip, and conduction passes to fingertip 2 from contact 1, and fingertip and fingertip seat are connected and fixed by screw 3, guarantees through-flowly, and fingertip will conduct electricity and pass to contact tube 7 by fingertip seat 6, and the contact pressure of fingertip and contact is by spring 4 assurances.
Claims (4)
1, external-compression type contact mechanism is characterized in that: fingertip is fixedlyed connected with the fingertip seat.
2, external-compression type contact mechanism according to claim 1 is characterized in that: fingertip is a U type fingertip, and the fingertip seat is fixedly connected by screw and the U type fingertip madial wall that is positioned at fingertip seat outer wall.
3, external-compression type contact mechanism according to claim 2 is characterized in that: between the two side arms spring is housed in the U type fingertip.
4, according to the arbitrary described external-compression type contact mechanism of claim 1-3, it is characterized in that: fingertip seat outside wall surface is equipped with protective cover.
