Abstract
Isolator with contact instruction function. It does not have contact deciliter instruction at the separating brake or when closing a floodgate mainly to solve present isolator, and it is visual just to adopt the transparency cover to do the contact, however electric arc sooting when the transparency cover is broken off by the product easily, the problem of the contact state of looking over that can't be clear. The utility model provides an isolator with contact instruction function has the indicator of clearance fit on its casing, exceed housing face when the separating brake under the roof pressure of moving contact, falls down during the combined floodgate to be less than housing face, the state of the embodiment contact that can understand, and it is more convenient to use.
Description
Technical field
The utility model relates to isolating switch field, has and relates to the isolating switch with contact deixis.
Background technology
When electrical equipment keeps in repair, need to cut off the electricity supply, maintenance part and live part are departed from, and the isolation distance of remaining valid, require can bear superpotential withstand voltage level between its point of fracture. Knife-like switch is as the device for switching of insulating power supply. The knife-like switch of insulating power supply is also called isolating switch. Isolation generally belongs to no-load break-make electrical equipment with knife-like switch, can only connect or disjunction " insignificant electric current " (referring to the capacitance current of bus with voltage, stub cable or the electric current of voltage transformer).
Present isolating switch is non-contact deciliter instruction in separating brake or combined floodgate, just adopts transparency cover to do contact visual, but transparency cover electric arc sooting while easily being disconnected by product cannot clearly be checked contact state.
Utility model content
In order to overcome the deficiency of background technology, the utility model provides the isolating switch with contact deixis, mainly solve the non-contact deciliter instruction in separating brake or combined floodgate of present isolating switch, just adopt transparency cover to do contact visual, but transparency cover electric arc sooting while easily being disconnected by product cannot clearly be checked the problem of contact state.
The technical scheme that the utility model adopts is:
There is the isolating switch of contact deixis, comprise housing, described housing is provided with operating grip, in described housing, be provided with the moving contact with described operating grip interlock, described housing is provided with through hole, activity is combined with indication piece in described through hole, settings corresponding to described moving contact of described indication piece, and depress primary importance higher than described surface of shell with combined floodgate when described indication piece comprises separating brake during on the described movable contact crown, whereabouts is not higher than the second place of described surface of shell.
On described through-hole side wall, be axially also provided with chute, described indication piece sidewall is provided with non return part that can folding, it is interior and corresponding with described chute bottom interior wall that described non return part stretches into described chute, between described indication piece and described case top inwall, is provided with elastic reset part.
Described indication piece comprises slide bar and the lead that correspondence is provided with, and described slide bar and described chute are slidably matched, and described non return part is located on described slide bar; In described housing, be provided with and the movable pilot hole for leading coordinating of described lead.
Described elastic reset part is spring.
Described spring housing is located at described slide bar outside.
Described indication piece is made into integration.
Described non return part is the shell fragment to downward-extension that described indication piece is provided with.
The beneficial effects of the utility model are: the utility model provides the isolating switch with contact deixis, on its housing, there is the movable indication piece coordinating, in the time of separating brake, depress and exceed surface of shell on the top of moving contact, when combined floodgate, fall lower than surface of shell, the state that can clearly embody contact, uses convenient.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail: as shown in the figure, there is the isolating switch of contact deixis, comprise housing 1, described housing 1 is provided with operating grip 2, in described housing 1, be provided with the moving contact 3 linking with described operating grip 2, described housing 1 is provided with through hole 11, the interior activity of described through hole 11 is combined with indication piece 4, the setting corresponding to described moving contact 3 of described indication piece 4, when depressing higher than the primary importance on described housing 1 surface when described indication piece 4 comprises separating brake on described moving contact 3 tops and closing a floodgate, fall not higher than the second place on described housing 1 surface. housing is provided with through hole, and in through hole, activity is combined with indication piece, and as shown in the figure, when moving contact rises, described indication piece is pressed on top, and indication piece rises place's surface of shell, is now separating brake, in fitting with static contact in moving contact whereabouts, indication piece falls less than or equal to surface of shell now for closing a floodgate thereupon, the utility model provides the isolating switch with contact deixis, on its housing, there is the movable indication piece coordinating, in the time of separating brake, depress and exceed surface of shell on the top of moving contact, when combined floodgate, fall lower than surface of shell, can clearly embody the state of contact, use convenient.
In the utility model, as shown in Figure 2, on described through hole 11 sidewalls, be axially also provided with chute 111, described indication piece 4 sidewalls are provided with non return part 41 that can folding, it is interior and corresponding with described chute 111 bottom interior wall that described non return part 41 stretches into described chute 111, between described indication piece 4 and described housing 1 top inner wall, is provided with elastic reset part 5. on indication piece, have be provided with can folding non return part, between indication piece 4 and described housing 1 top inner wall, be provided with elastic reset part 5, in the time that indication piece is movable in through hole, non return part is movable in chute, in the time that indication piece is positioned at the second place, non return part bottom is pressed on chute bottom, (as preferably also the sidewall of the sidewall of non return part and described chute being compressed), elastic reset part can be realized the function that indication piece resets when moving contact leaves indication piece, non return part can shrink when non return part is installed in through hole from via bottoms in folding, put in place to open to realize after corresponding with chute and prevent the function that indication piece drops out from through-hole wall.
In the utility model, as shown in the figure, described indication piece 4 comprises slide bar 43 and the lead 42 that correspondence is provided with, and described slide bar 43 is slidably matched with described chute 111, and described non return part 41 is located on described slide bar 43; In described housing 1, be provided with and the movable pilot hole 12 for leading coordinating of described lead 42. The stability of further strengthening indication piece operation, result of use is better, and when indication piece is fallen lowest part, be non return part with chute bottom when compressing, can realize the effect of location, prevent from that indication piece is monolateral to slant.
In the utility model, as shown in the figure, described elastic reset part 5 is spring. Also can adopt other elastic components herein, as elastic rubber ring, shell fragment etc., spring is preferred version, simple in structure, cost is lower.
In the utility model, as shown in the figure, described spring housing is located at described slide bar 43 outsides. Easy to assembly, more stable when motion, result of use is good.
