Abstract
It include bracket and movable plate on the shell the utility model discloses a kind of high-current microswitch, including shell, bracket is ladder-like in bending, its inner end and one end of movable plate connect, and outer end is stretched out outside the shell, and one end of the movable plate is equipped with the button that control is powered；Movable plate is placed in the shell, the other end be equipped with contact, and with the inner end of first terminal formed it is normally closed contact, Second terminal is arranged in parallel with the first terminal, forms normally opened contact with the movable plate.The inner end of bracket is fixed the utility model with movable plate, and containing of the movement of movable plate by bracket, so that in desired extent, contact failure will not occur for the motion profile of movable plate, structure is simple, long service life.
Description
Technical field
The utility model relates to switch, and in particular to high-current microswitch.
Background technique
Microswitch has small contact separation and snap-action mechanism, carries out switch motion with defined stroke and defined power
Contact mechanism, covered with shell because its switch contact spacing it is smaller, therefore named microswitch is called sensitive switch.Outside
Mechanical force is acted on power on movement reed by actuated element (push-piece, button, lever, idler wheel etc.), when movement reed displacement
To snap action is generated when critical point, make the movable contact and fixed contact quick-make or the disconnection that act reed end.
The structure of existing microswitch is typically more complicated, small by electric current, is easy to appear failure.
In view of this, being badly in need of carrying out structure improvement to existing microswitch, simplify modular construction, increase current power,
Prolong the service life.
Utility model content
Technical problem to be solved in the utility model is that existing microswitch structure is complicated, it is small to pass through electric current, uses
Service life short problem.
In order to solve the above-mentioned technical problem, technical solution used by the utility model is to provide a kind of high current fine motion and opens
It closes, including shell, includes on the shell：
Bracket, in the ladder-like of bending, one end of inner end and movable plate is connected, and outer end is stretched out outside the shell, described
One end of movable plate is equipped with the button that control is powered；
Movable plate is placed in the shell, the other end be equipped with contact, and with the inner end of first terminal formed it is normally closed contact,
Second terminal is arranged in parallel with the first terminal, forms normally opened contact with the movable plate.
In another preferred embodiment, the button stretches out outside the shell, and the inner end of the button is equipped with convex
Platform, the boss are resisted against on the inner wall of the shell.
In another preferred embodiment, the inner wall of the shell is equipped with and the first terminal and the second end
The fixture block of son adaptation.
In another preferred embodiment, in a rectangular parallelepiped shape, the both ends on diagonal line are equipped with hole post, institute to the shell
Button setting is stated in cornerwise side, the bracket, first terminal and the Second terminal are arranged in cornerwise other side.
Compared with prior art, the inner end of the movable plate of bracket is fixed the utility model, the movement of movable plate by
To the containing of bracket, so that in desired extent, contact failure will not occur for the motion profile of movable plate, structure is simple, uses
Service life is long.
Detailed description of the invention
Fig. 1 is the schematic diagram of internal structure of the utility model.
Specific embodiment
The utility model provides a kind of high-current microswitch, by the motion profile of movable plate in desired extent, no
Contact failure can occur, structure is simple, long service life.It is practical new to this with specific embodiment with reference to the accompanying drawings of the specification
Type is described in detail.
As shown in Figure 1, a kind of high-current microswitch provided by the utility model includes shell 10, it include branch on shell 10
Frame 20 and movable plate 30.Wherein, in the ladder-like of bending, inner end is connect bracket 20 with one end of movable plate 30, and outer end is stretched out
Outside shell 10, one end of movable plate 30 is equipped with the button 60 that control is powered.Movable plate 30 is placed in shell 10, and the other end is equipped with touching
Point 31, and with the inner end of first terminal 40 formed it is normally closed contact, Second terminal 50 is arranged in parallel with first terminal 40, with movable plate
30 form normally opened contact.
Stair-stepping bracket 20 reduces space shared by bracket 20, and makes bracket 20 and internal movable plate
30, the spacing of first terminal 40 and Second terminal 50 reduces, so that more compact structure, saves processing cost.
Button 60 stretches out outside shell 10, and the inner end of button 60 is equipped with boss, and boss is resisted against on the inner wall of shell 10.It presses
The boss of button 60 can effectively ensure that button 60 and movable plate 30 keep being in close contact.
The inner wall of shell 10 is equipped with the fixture block 51 being adapted to first terminal 40 and Second terminal 50, and the structure of fixture block 51 is protected
The position for having demonstrate,proved first terminal 40 and Second terminal 50 is stablized, thus it is effectively and accurate with the contact of movable plate 30, it improves out
The accuracy of pass movement.
In a rectangular parallelepiped shape, the both ends on diagonal line are equipped with hole post 70 to shell 10, and button 60 is arranged in cornerwise side,
Bracket 20, first terminal 40 and Second terminal 50 are arranged in cornerwise other side.The position of hole post 70 and bracket 20, first end
The realization of the position of son 40 and Second terminal 50 is good fit, both can guarantee integrally-built stability, but also structure is more tight
It gathers.
The application method (course of work) of the utility model is as follows：
The utility model, movable plate 30 and first terminal 40 are powered when not operating, when pressing lower button 60 under external force,
Movable plate 30 is driven, the other end of movable plate 30 moves down and contact 31 and connects with Second terminal 50, to complete to open
It opens.Conversely, can realize shutdown using opposite action.
The utility model is not limited to above-mentioned preferred forms, and anyone should learn that the enlightenments in the utility model
Under the structure change made, it is all that there is same or similar technical solution with the utility model, each fall within the utility model
Within protection scope.
