Abstract
A two-way open-type isolating switch, which comprises an installation board, an upper static contact and its upper terminal strip, a middle static contact and its middle terminal strip, a lower static contact and its lower terminal strip, a movable contact, an axis and its insulating bushing, a tow rod and its insulating bushing; the upper contact is integrated with the upper terminal strip, the middle contact is integrated with the middle terminal strip, the lower contact is integrated with the lower terminal strip; the vertical part of the upper contact, middle contact and lower contact are changed to the elastic U-shaped structure; the movable contact is changed to a monolithic. The utility model has advantages of reliable contact, simple processing procedure, low material consumption and low cost.
Description
One, affiliated technical field
The utility model relates to a kind of isolating switch, refers in particular to a kind of double-throw open-type isolating switch that HS type series double-throw open type knife switch is carried out significant improvement.
Two, background technology
At present, HS11, HS12, HS13 series double-throw knife switch be applicable to exchange 50Hz, rated voltage to 380V, direct current to 440V, rated current is to the complete power distribution equipment of 1500A, as manually not connecting continually and disjunction AC and DC circuit or make isolating switch usefulness.Wherein the double-throw knife switch of central handle formula is mainly used in the magnetic force station, does not cut off the circuit that has electric current, as the usefulness of isolating switch.As switch, contact system is very important.Contact system should accomplish that contact is good, also will accomplish to save material.Contact system generally all is made of moving contact and fixed contact.At present, HS type Series Switch-disconnector is by mounting panel, upper static contact and go up lug plate, middle fixed contact reaches middle lug plate, following fixed contact and lug plate, moving contact, axle and insulating sleeve, insulating part, draw bar constitute down, its fixed contact all is a monolithic, moving contact all is two pieces, and adopting the pressure shell fragment to clamp, lug plate is also separately as a part.Like this, operation is many, and part is many, and consumptive material is many, makes complexity, the cost height.
Three, utility model content
The purpose of this utility model is to overcome the above-mentioned defective that prior art exists, and a kind of double-throw open-type isolating switch is provided, and its contact is reliable, and manufacturing procedure is simple, and consumptive material is few, and cost is lower.
For achieving the above object, the solution that the utility model is taked is: a kind of double-throw open-type isolating switch, it is by mounting panel, upper static contact and go up lug plate, middle fixed contact reaches middle lug plate, following fixed contact and lug plate, moving contact, axle and insulating sleeve, draw bar and insulating case constitute down, upper static contact and last lug plate combine as a whole, middle fixed contact and middle lug plate combine as a whole, following fixed contact combines as a whole with following lug plate, upper static contact, middle fixed contact and following fixed contact standing portion change resilient U type structure into, and moving contact changes en-block construction into.
The utility model part unlike the prior art is contact system, upper static contact and last lug plate combine as a whole as a part, middle fixed contact and middle lug plate combine as a whole as a part, following fixed contact combines as a whole as a part with following lug plate, moving contact changes en-block construction into, upper static contact, middle fixed contact and following fixed contact standing portion change resilient U type structure into, not only reached and contacted good requirement, and compared with prior art save copper material about 40%, manufacturing procedure has reduced half, make simply, greatly reduce cost.
Four, description of drawings
Fig. 1 is the vertical view of present embodiment.
Fig. 2 is the side-looking fragmentary cross-sectional view of present embodiment.
Among the figure: 1, mounting panel, 2, insulating sleeve, 3, fixed contact down, 5, upper static contact, 6, spring coil, 7, moving contact, 9, axle, 10, draw bar, 11, insulating case, 12, middle fixed contact, 13, disc spring.
Five, embodiment
Below in conjunction with embodiment and accompanying drawing thereof the utility model is remake description.
Referring to Fig. 1 and Fig. 2, a kind of double-throw open-type isolating switch, it by mounting panel 1, upper static contact 5 and go up lug plate, middle fixed contact 12 and in lug plate, fixed contact 3 and lug plate, moving contact 7, axle 9 and insulating sleeve 2, draw bar 10 and insulating case 11 constitute down down, upper static contact 5 combines as a whole with last lug plate, middle fixed contact 12 combines as a whole with middle lug plate, following fixed contact 3 combines as a whole with following lug plate, upper static contact 5, middle fixed contact 12 and following fixed contact 3 standing portion change resilient U type structure into, and moving contact 7 changes en-block construction into.
Referring to Fig. 1 and Fig. 2, upper static contact 5 and following fixed contact 3 standing portion are embedded with spring coil 6, make upper static contact 5 and following fixed contact 3 standing portion produce enough elastic force, the contact reliability when raising moving contact 7 and fixed contact are closed.
Referring to Fig. 1 and Fig. 2, middle fixed contact 12 outer two sides linings improve moving contact 7 and middle fixed contact 12 contact reliabilities with disc spring 13.
