Description
Technical field
The present invention relates to a kind of switches, limit universal switch more particularly to a kind of fine motion.
Background technique
Microswitch is that have small contact separation and snap-action mechanism, and it is dynamic to carry out switch with defined stroke and defined power
The contact mechanism of work.At present the developing direction of microswitch technology first is that switch size minimize.But existing microswitch
Installation hole location use diagonal mounting means or central symmetry horizontal mode, the mounting hole bit architecture of both modes will lead to out
After closing installation screw, connector and metal screws creepage distance and electric clearance are insufficient, can only go to solve by increasing switch size
Certainly this problem, it is clear that this has deviated from the requirement of switch size miniaturization.
In addition, one is directly born against using screw there are two types of the assembly methods of existing microswitch cover and bottom case
Locking is covered, such mounting means needs strict control torque, can make plastic deformation otherwise to make switch internal reduced space
Or connector locating bias, causing switch to occur, signal flashes or circut breaking, switch parameter are unstable.Another way is spiral shell
Silk is directly born against on plastics bottom case boss, while being stretched out plastic column from bottom case and being passed through upper cover, then is solid with this by melting plastic column
Determine upper cover.The problem of such scheme is, switch, which needs to return man-hour requirement, which destroys shell, can just turn on the switch, working service it is inconvenient and
Higher cost.
Summary of the invention
Goal of the invention: in order to solve the problems existing in the prior art, the present invention, which provides one kind, can be avoided connector and metal
The fine motion of screw creepage distance and electric clearance deficiency and assembly method simple and flexible limits universal switch.
Technical solution: a kind of fine motion limit universal switch of the present invention, including bottom case and cover, and be arranged in bottom case
It is equipped with groove structure with the side of the work package among cover, the bottom case upper surface, work package is arranged in groove；It is recessed
Trough rim outer frame portion is mounting plate, and mounting plate matches with cover shape, which is provided with three card slots, the respectively first card
Slot, the second card slot and third card slot；First card slot is located at the side far from groove, and the second card slot and third card slot are located at groove
The other side；The cover is equipped with three corresponding with the card slot of bottom case buckles, the respectively first buckle, the second buckle and third
Buckle；Cover is clamped on bottom case by the cooperation of buckle and card slot；The bottom case is additionally provided with boss, and boss is positioned close to fill
Side with the first card slot of platform, and same plane or more slightly higher than cover is in cover, on boss and cover composition switch
Surface,
Boss two sides are respectively equipped with the first mounting hole and the second mounting hole of perforation bottom case upper and lower surface.
Wherein, first mounting hole and the second mounting hole are non-metallic insulation material.
First mounting hole and the second mounting hole are installed by bolt, and bolt head outer diameter is than installation hole location to boss side
Back gauge is big.
The utility model has the advantages that a kind of fine motion of the present invention limits universal switch, using two plastic mounting hole side installation sides
Formula can make metal bolts far from hot insertion part, can effectively increase metal bolts and connector electric clearance and creepage distance,
It is safe and reliable, while also making to switch compact overall structure and compact in size；Bottom case and cover are filled using buckle and card slot
Cover is further reinforced with mode, while by designing bolt head outer diameter size, assembly method is simple and convenient, and stabilization can
It leans on.

Specific embodiment
The present invention is described in further details with reference to the accompanying drawing.
As shown in Figs. 1-5, a kind of fine motion of the present invention limits universal switch, including bottom case 1 and cover 2, Yi Jishe
The work package among bottom case 1 and cover 2 is set, the side of 1 upper surface of bottom case is equipped with groove structure, work package arrangement
In groove, work package includes activity bar assembly, movable component, movable contact spring component, rolling element, public pin 16 and plug-in pin
Component；Activity bar assembly is pressed in movable component one end, and the other end presses movable contact spring component, and movable contact spring component is in movable component pressure
Lower movement is simultaneously kept in contact with rolling element, and rolling element is kept in contact with public pin 16, and plug-in pin component passes through movable contact spring component
Be connected to or disconnect with public pin 16, plug-in pin component be at least one of normally closed plug-in pin 18, normally opened plug-in pin 17, both
Refer to that plug-in pin component can be normally closed plug-in pin 18, can be normally opened plug-in pin 17, is also possible to normally opened plug-in pin 17 and often
Close plug-in pin 18；Public pin 16 is arranged in the side of groove with plug-in pin component, and stretches out outside bottom case.Outside groove frame
It is mounting plate, mounting plate matches with cover shape, and cover may be mounted on mounting plate, and mounting plate is equipped with three
A card slot, respectively the first card slot 13, the second card slot 14 and third card slot 15；First card slot 13 is located at the side far from groove,
Specifically, the first card slot 13 is setting apart from public pin 16 and the farther away side of plug-in pin component, 14 He of the second card slot
Third card slot 15 is located at the other side of groove, has both referred to that the position of the second card slot 14 and third card slot 15 is located at apart from public pin
16 with the closer side of plug-in pin component；The cover 2 is equipped with three corresponding with the card slot of bottom case and buckles, and respectively first
The 21, second buckle 22 of buckle and third buckle 23, the first buckle 21 is corresponding with 13 position of the first card slot, the second buckle 22 and second
14 position of card slot is corresponding, and third buckle 23 is corresponding with 15 position of third card slot；Cover 2 is clamped on by the cooperation of buckle and card slot
On bottom case；Switch internal reduced space or connector positioning are inclined caused by this assembly method is effectively prevented because of the turn of the screw
It moves, and then avoids switch from the phenomenon that signal flashing or power-off occur, and this assembly method dismounts simple and flexible, use
It is convenient.The bottom case is additionally provided with boss, and boss is arranged in the side of the first card slot 13, boss and cover 2 be in same plane or
Person is more slightly higher than cover 2, and the two group cost fine motion limits the upper surface of universal switch, and the corresponding position in boss two sides, which is respectively equipped with, to be passed through
The first mounting hole 11 and the second mounting hole 12 of logical 1 upper and lower surface of bottom case, the first mounting hole 11 and the second mounting hole 12 are non-gold
Belong to isolation material, and circuit of the two apart from work package is farther out, the bolt of subsequent installation farther out, can have apart from hot insertion part
Effect avoids the problem of metal bolts Yu connector electric clearance and creepage distance deficiency, works more safe and reliable, while also making
Switch compact overall structure and compact in size.When design, bolt head outer diameter comes than bottom case screw hole location to side distance
Greatly, the sub-fraction of head outer diameter encounters bottom case 1 or close to bottom case 1, cover 2 can be made to have small pine when bolt is locked
Without departing from bottom case 1 when dynamic, more securely and reliably.
