Abstract
The utility model relates to a switch, in particular to big clearance micro -gap switch. The utility model provides a following technical scheme: a normally open static contact, normal close static contact that big clearance micro -gap switch, including shell, button, locate the shell in and a movable contact spring that can switch on with normally opening the quiet male contact of static contact or normal close through the button drive the movable contact spring erect in the shell through the support, normally open static contact and normal close static contact and be the setting of parallel form, the movable contact spring extends to to be normally opened between static contact and the normal close static contact, is equipped with on the shell that supply to normally open the static contact and the inserting groove of establishing is inserted to the normal close static contact, just normally open the static contact and the normal close static contact sets firmly in the inserting groove through the fastener respectively. Adopt above -mentioned technical scheme, provide safe in utilization a, simple structure's big clearance micro -gap switch.
Description
Technical field
The utility model relates to a kind of switch, particularly a kind of wide arc gap sensitive switch.
Background technology
Sensitive switch has small contact clearance and snap-action mechanism, carries out the contact mechanism of switch motion with the stroke specified and specified force.
Traditional sensitive switch primarily of shell, button, be located in shell often open fixed contact, normally closed fixed contact and driven by button can with the movable contact spring often opening fixed contact or normally closed fixed contact and contact conducting.But traditional gap of often opening between fixed contact and normally closed fixed contact is less, in use easily produce larger electric arc, for sensitive switch and the larger potential safety hazard of overall circuit existence.
Summary of the invention
For the deficiency that prior art exists, the utility model provides a kind of use safety, the simple wide arc gap sensitive switch of structure.
For achieving the above object, the utility model provides following technical scheme: a kind of wide arc gap sensitive switch, include shell, button, be located at and often open fixed contact in shell, normally closed fixed contact and driven by button can with the movable contact spring often opening fixed contact or normally closed fixed contact and contact conducting, described movable contact spring is set up in shell by support, it is characterized in that: described often open fixed contact and normally closed fixed contact is that parallel shape is arranged, movable contact spring extends to often to be opened between fixed contact and normally closed fixed contact, shell is provided with the inserting groove for often to open fixed contact and normally closed fixed contact and plug, and often open fixed contact and normally closed fixed contact is fixedly arranged in inserting groove respectively by securing member.
Adopt technique scheme, often open fixed contact and normally closed fixed contact is that parallel shape is located in shell, and movable contact spring extends to often to be opened between fixed contact and normally closed fixed contact, after arranging like this, movable contact spring with often open fixed contact and normally closed fixed contact implement to be separated or the stroke of conducting comparatively stable, impel the relative traditional sensitive switch of spacing often opened between fixed contact with normally closed fixed contact further to expand, prevent the generation of a large amount of electric arc, the potential safety hazard existed when eliminating use.
The utility model is set to further: often open fixed contact and normally closed fixed contact and be respectively and have flexible conducting strip, the one end of often opening fixed contact and normally closed fixed contact and shell fixing is stiff end, the other end is conducting end, is connected between its stiff end with conducting end by inclined-plane link.
Adopt technique scheme, it is simple that structure is set like this, connects compact, and after stiff end is connected by inclined-plane link with conducting end, the elastic force often opening fixed contact and normally closed fixed contact can be made better.
The utility model is further set to: be provided with one end in shell and shell is conflicted, the back-moving spring that the other end and movable contact spring are conflicted.
Adopt technique scheme, setting can make movable contact spring in use can self-return like this.
Below in conjunction with accompanying drawing, the utility model is further described.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is normally closed fixed contact and often open the schematic perspective view of fixed contact in the utility model embodiment.
Embodiment
As Fig. 1, a kind of wide arc gap sensitive switch shown in Fig. 2, include shell 1, button 2, be located at and often open fixed contact 3 in shell 1, normally closed fixed contact 4 and driven by button 2 can with the movable contact spring 5 often opening fixed contact 3 or normally closed fixed contact 4 and contact conducting, movable contact spring 5 is set up in shell 1 by support 6, often open fixed contact 3 to arrange in parallel shape with normally closed fixed contact 4, movable contact spring 5 extends to often to be opened between fixed contact 3 and normally closed fixed contact 4, shell 1 is provided with the inserting groove 11 for often to open fixed contact 3 and normally closed fixed contact 4 and plug, and often open fixed contact 3 and normally closed fixed contact 4 is fixedly arranged in inserting groove respectively by securing member.In such scheme, often opening fixed contact 3 is located in shell 1 with normally closed fixed contact 4 in parallel shape, and movable contact spring 5 extends to often to be opened between fixed contact 3 and normally closed fixed contact 4, after arranging like this, movable contact spring 5 with often open fixed contact 3 and normally closed fixed contact 4 implement to be separated or the stroke of conducting comparatively stable, impel the relative traditional sensitive switch of spacing often opened between fixed contact 3 with normally closed fixed contact 4 further to expand, prevent the generation of a large amount of electric arc, the potential safety hazard existed when eliminating use.
In the utility model embodiment, in order to make often to open fixed contact 3 and the connection between normally closed fixed contact 4 and shell 1 is more compact and simple, often open fixed contact 3 and normally closed fixed contact 4 to be respectively there is flexible conducting strip, the one end of often opening fixed contact 3 and normally closed fixed contact 4 and shell 1 fixing is stiff end a, the other end is conducting end b, and its stiff end a is connected by inclined-plane link c with between conducting end b.After stiff end a is connected by inclined-plane link c with conducting end b, the elastic force often opening fixed contact 3 and normally closed fixed contact 4 can be made better.
In order to make movable contact spring 5 can self-return after button 2 presses, the work being convenient to next time with this, be provided with one end in shell 1 and shell 1 is conflicted, the back-moving spring 7 that the other end and movable contact spring 5 are conflicted.
