Abstract
A kind of isolating switch, comprise base plate, insulator, control crank, rotating shaft, fixed contact, carry out the moving contact of opening a sluice gate or barrier gate coordinates with fixed contact, moving contact interval is fixed in rotating shaft, it is characterized in that, control crank is from the elongated hole base plate through fixing with rotating shaft, and fixed contact is connected with rotating shaft by insulator, the upper and lower one_to_one corresponding of fixed contact, moving contact and copper bar; Copper bar is fixed on the lower end of base plate.The isolating switch of the design is easy for installation, simple to operate, use safety.
Description
Technical field
The utility model relates to technical field of electric control, is specifically related to a kind of isolating switch.
Background technology
Isolating switch is a kind of conventional electric controling element, its effect is in the non-loaded situation of electrical equipment isolate, connect, conversion electrified body and electrical equipment between contact.At present conventional isolating switch needs to be fixed on by insulator on a bracing frame usually, usually installs cumbersome, also will at installation site fixing device for installing, so that fixing support rack.
Utility model content
The technical problem that the utility model solves is to provide a kind of isolating switch, to solve the shortcoming in above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: provide a kind of isolating switch, comprises base plate 1, insulator 2, fixed contact 3, installing hole 5, control crank 7, rotating shaft 8, carry out the moving contact 4 of opening a sluice gate or barrier gate coordinates with fixed contact 3, moving contact 4 interval is fixed in rotating shaft 8, it is characterized in that, control crank 7 is fixed from the elongated hole 6 base plate through with rotating shaft 8, and fixed contact 3 is connected with rotating shaft 8 by insulator 2, fixed contact 3, moving contact 4 and copper bar about 9 one_to_one corresponding; Copper bar 9 is fixed on the lower end of base plate 1.
Described installing hole 5 is four, is arranged on base plate 1.
The beneficial effects of the utility model are, isolating switch of the present utility model is easy for installation, need not install bracing frame again, have reserved installing hole.Because three copper bars can connect ground wire, live wire, zero line, ensure that the safety of use.The beneficial effects of the utility model are: easy to operate, structure is simple, enhances productivity.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of isolating switch.
Embodiment
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
As Fig. 1: base plate 1, insulator 2, fixed contact 3, moving contact 4, installing hole 5, elongated hole 6, control crank 7, rotating shaft 8, copper bar 9.
A kind of isolating switch, comprises base plate 1, insulator 2, fixed contact 3, installing hole 5, control crank 7, rotating shaft 8, the moving contact 4 of opening a sluice gate or barrier gate coordinates is carried out with fixed contact 3, moving contact 4 interval is fixed in rotating shaft 8, it is characterized in that, control crank 7 is fixed from the elongated hole 6 base plate through with rotating shaft 8, fixed contact 3 is connected with rotating shaft 8 by insulator 2, fixed contact 3, moving contact 4 and copper bar about 9 one_to_one corresponding; Copper bar 9 is fixed on the lower end of base plate 1.
Described installing hole 5 is four, is arranged on base plate 1.
When control crank 7 moves up and down, drive rotating shaft 8 to rotate, insulator 2 rotates along with rotating shaft 8, and drive moving contact 4 and fixed contact 3 separating brake or combined floodgate, make circuit turn-on or disconnection, the lower end of base plate 1 is fixed with three copper bars 9, respectively earth connection, live wire, zero line.Isolating switch of the present utility model is installed directly be screwed by installing hole 5.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model, the technical staff of the industry should understand, the utility model is not restricted to the described embodiments, what describe in above-described embodiment and specification just illustrates principle of the present utility model, under the prerequisite not departing from the utility model spirit and scope, the utility model also has various changes and modifications, these changes and improvements all fall within the scope of claimed the utility model, the claimed scope of the utility model is defined by appending claims and equivalent thereof.
