Description
Technical field
The present invention relates to one kind switch, more particularly to a kind of spacing universal switch of fine motion.
Background technology
Microswitch is, with small contact separation and snap-action mechanism, switch to be carried out with defined stroke and defined power dynamic
The contact mechanism of work.One of developing direction of current microswitch technology is switch size miniaturization.But, existing microswitch
Mounting hole site use diagonal mounting means or Central Symmetry horizontal mode, the mounting hole site structure of both modes can cause to hold
Close and install after screw, connector and metal screws creep age distance and electric clearance are not enough, solution can only be gone by increasing switch size
Certainly this problem, it is clear that this has deviated from the requirement of switch size miniaturization.
In addition, the assembling mode of existing microswitch cover and drain pan has two kinds, one kind is directly born against using screw
Locking is covered, such a mounting means needs strict control mode, otherwise can make plastic deformation so that switch internal reduced space
Or connector locating bias, cause switch signal flicker or circut breaking occur, switch parameter is unstable.Another way is spiral shell
Silk is directly born against on plastics drain pan boss, while stretching out plastic column from drain pan passes through upper lid, then it is solid with this by melting plastic column
Fixed upper lid.The problem of such a scheme is, switch, which needs to return man-hour requirement destruction shell, could open switch, working service it is inconvenient and
Cost is higher.
The content of the invention
Goal of the invention：To solve the problem of prior art is present, the present invention, which provides one kind, can avoid connector and metal
The spacing universal switch of fine motion of screw creep age distance and electric clearance deficiency and assembling mode simple and flexible.
Technical scheme：The spacing universal switch of a kind of fine motion of the present invention, including drain pan and cover, and it is arranged on drain pan
With the work package in the middle of cover, the side of the drain pan upper surface is provided with groove structure, and 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 necks, the respectively first card
Groove, the second neck and the 3rd neck；First neck is located at the side away from groove, and the second neck and the 3rd neck are located at groove
Opposite side；The cover is provided with three buckles corresponding with the neck of drain pan, respectively the first buckle, the second buckle and the 3rd
Buckle；Cover is clamped on drain pan by the cooperation of buckle and neck；The drain pan is additionally provided with boss, and boss is positioned close to dress
Side with the neck of platform first, and it is in same plane or more slightly higher than cover with cover, boss is switched with cover composition
Surface,
Boss both sides are respectively equipped with the first mounting hole and the second mounting hole of insertion drain pan upper and lower surface.
Wherein, first mounting hole and the second mounting hole are non-metallic insulation material.
First mounting hole is installed with the second mounting hole by bolt, and bolt head external diameter is than mounting hole site to boss side
Back gauge is big.
Beneficial effect：The spacing universal switch of a kind of fine motion of the present invention, using two plastic mounting hole side installation sides
Formula, can make metal bolts away from hot insertion part, can effectively increase metal bolts and connector electric clearance and creep age distance,
It is safe and reliable, while also making switch compact overall structure and compact in size；Drain pan is filled with cover using buckle and neck
With mode, while further reinforcing cover by designing bolt head external diameter size, assembling mode is simple and convenient, and stably may be used
Lean on.

Embodiment
The present invention is described in further details below in conjunction with the accompanying drawings.
As Figure 1-5, the spacing universal switch of a kind of fine motion of the present invention, including drain pan 1 and cover 2, Yi Jishe
The work package in the middle of drain pan 1 and cover 2 is put, the side of the upper surface of drain pan 1 is provided 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 motion simultaneously keeps contacting with rolling element, and rolling element keeps contacting with public pin 16, and plug-in pin component passes through movable contact spring component
Connect or disconnect with public pin 16, plug-in pin component is at least one in normally closed plug-in pin 18, normally opened plug-in pin 17, both
It can be normally closed plug-in pin 18 to refer to plug-in pin component, can be normally opened plug-in pin 17 or normally opened plug-in pin 17 and normal
Close plug-in pin 18；Public pin 16 is arranged in the side of groove with plug-in pin component, and stretches out outside drain pan.Outside groove frame
It is mounting plate, mounting plate matches with cover shape, and cover may be mounted on mounting plate, mounting plate is provided with three
Individual neck, respectively the first neck 13, the second neck 14 and the 3rd neck 15；First neck 13 is located at the side away from groove,
Specifically, the first neck 13 is provided in apart from public pin 16 and the side of plug-in pin component farther out, the He of the second neck 14
3rd neck 15 is located at the opposite side of groove, has both referred to that the position of the second neck 14 and the 3rd neck 15 is located at apart from public pin
16 with the nearer side of plug-in pin component；The cover 2 is provided with corresponding with the neck of drain pan three buckles, respectively first
Buckle 21, the second buckle 22 and the 3rd buckle 23, the first buckle 21 are corresponding with the position of the first neck 13, the second buckle 22 and second
The position of neck 14 correspondence, the 3rd buckle 23 is corresponding with the position of the 3rd neck 15；Cover 2 is clamped on by the cooperation of buckle and neck
On drain pan；This assembling mode effectively prevent because switch internal reduced space caused by the turn of the screw or connector positioning are inclined
Move, and then avoid switching the phenomenon for signal flicker or power-off occur, and this assembling mode dismounts simple and flexible, uses
It is convenient.The drain pan is additionally provided with boss, and boss is arranged on the side of the first neck 13, boss and cover 2 be in same plane or
Person is more slightly higher than cover 2, and both constitute the upper surface of the spacing universal switch of this fine motion, and the corresponding position in boss both sides, which is respectively equipped with, to be passed through
The first mounting hole 11 and the second mounting hole 12 of the logical upper and lower surface of drain pan 1, the first mounting hole 11 and the second mounting hole 12 are non-gold
Belong to isolation material, and both apart from work package circuit farther out, the bolt of subsequent installation farther out, can have apart from hot insertion part
Effect avoids the problem of metal bolts are with connector electric clearance and not enough creep age distance, works more safe and reliable, while also making
Switch compact overall structure and compact in size.During design, bolt head external diameter comes than drain pan screw hole position to side distance
Greatly, the sub-fraction of head outer diameter encounters drain pan 1 or close to drain pan 1 when bolt is locked, and cover 2 can be made to have small pine
It is more safe and reliable without departing from drain pan 1 when dynamic.
