Abstract
The utility model discloses a waterproof micro switch which comprises a base, a cover plate, a terminal and a switch casing. The terminal extends to the base; the switch casing is formed by the base and the cover plate in a fastening mode; a moveable spring, an elastic piece, a moving contact and a fixed contact are installed in the casing; the moveable spring controls on and off of the moving contact and the fixed contact through a key; the fastening surface of the base and the cover plate extrudes a waterproof sealing ring, and the joint surface of the waterproof sealing ring and the base and the cover plate is in a plane structure. According to the waterproof micro switch, dispensing is adopted to seal the position where the key is installed on the cover plate, the terminal is integrated with the base in an injection molding mode, the silicone sealing ring is used for waterproofing on the base and the cover plate, and the production efficiency is improved; the waterproof sealing ring arranged at the fastening position of the base and the cover plate is designed into the plane structure, and the contacting area of the waterproof sealing ring with the base plane is enlarged simultaneously, therefore the problem of waterproof failure of the switch caused by displacement of the waterproof sealing ring is solved.
Description
Technical field
The utility model discloses a kind of waterproof micro switch, divides by International Patent Classification (IPC) (IPC) to belong to sensitive switch manufacturing technology field.
Background technology
Sensitive switch; Being outer mechanical force is used to move reed through actuated element (push-piece, button, lever, roller etc.) with masterpiece; When the action reed is displaced to critical point, produce instantaneous operation, terminal moving contact and the fixed contact of action reed is switched on or switched off fast.Waterproof micro switch is the switch with water-proof function, and water proof switch adopts the dress button, dress terminal and pedestal cover plate junction point glue, and this mode production efficiency is low.The switch waterproof construction is high to matching requirements, and the cross section of middle water proof ring is a circular configuration, is prone to the water proof ring positioning in the assembling process and causes water-proof function not enough; And single water proof ring quadric injection mould structure in the employing of high-end producer; Stability Analysis of Structures, but cost is higher, is unfavorable for opening up the client.
Summary of the invention
To the deficiency of prior art, the utility model provides a kind of waterproof micro switch of rational in infrastructure, long service life.
For achieving the above object, the utility model is realized through following technical scheme:
A kind of waterproof micro switch; Comprise pedestal, cover plate and extend to the terminal of pedestal; Comprise that pedestal and cover plate fasten the formation switch case, movable contact spring, shell fragment and sound contact are housed in the housing, movable contact spring is by being switched on or switched off by the dynamic and static contact of key control; The buckling surface extruding waterproof grommet of described pedestal and cover plate, the faying face of this waterproof grommet and pedestal and cover plate is a planar structure.
Further, the buckling surface of described cover plate and pedestal is provided with projection one circle boss to push the plane waterproof grommet more closely.
Further, described terminal adopts and the moulding of pedestal integral molded plastic.
Further, described button is exposed on the cover plate, and button is furnished with water proof ring, and adopts the sealing of some glue in cover plate dress button position.
The utility model water proof switch adopts some glue seals at except cover plate dress button position, and terminal adopts and the moulding of pedestal integral molded plastic, and pedestal and cover plate adopt the silica gel sealing ring waterproof, have avoided two place's point glue steps in the assembling switching process, have improved production efficiency.The utility model is designed to plane form with the water proof ring at pedestal and cover plate fastening place, strengthens the area that water proof ring contacts with base plane simultaneously, prevents the water proof ring positioning and causes switch waterproof failure problem thereby reach.

Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
Embodiment: see also Fig. 1 to Fig. 4; A kind of waterproof micro switch comprises pedestal 2, cover plate 1 and extends to the terminal 3 of pedestal, and pedestal 2 fastens with cover plate 1 and forms switch case; Movable contact spring 5, shell fragment 8 and dynamic and static contact 10,9 are housed in the housing; Movable contact spring is switched on or switched off by the dynamic and static contact of button 7 controls, and described pedestal 2 pushes waterproof grommet 4 with the buckling surface of cover plate 1, and the faying face of this waterproof grommet and pedestal and cover plate is a planar structure.Described cover plate 1 is provided with projection one circle boss with the buckling surface of pedestal 2, to push the plane waterproof grommet more closely.Described terminal 3 adopts and pedestal 2 integral molded plastic moulding.Described button 7 is exposed on the cover plate, and button is furnished with water proof ring 6, and adopts the sealing of some glue in cover plate dress button position.
The sealing of some glue is adopted in the cover plate dress button position of the utility model, and terminal adopts and the moulding of pedestal integral molded plastic, and pedestal and cover plate adopt the silica gel sealing ring waterproof, have improved production efficiency.The utility model is designed to plane form with the water proof ring at pedestal and cover plate fastening place, strengthens the area that water proof ring contacts with base plane simultaneously, prevents the water proof ring positioning and causes switch waterproof failure problem thereby reach.
The utlity model has following beneficial effect:
1, switch cooperates airtight, compact, no gap;
2, the switching manipulation spring is sensitive, and mechanism is flexible, no catching phenomenon;
3, action force: 80 ± 20gf; Bounce: more than the 15gf;
4, contact resistance: 50m Ω; Insulation resistance:>100 M Ω (500VDC); Proof voltage: AC1000V/1min between terminal, between terminal and shell: AC1500V/1min;
5, mechanical endurance: more than 5,000,000 times, 60 times/per minute; Electrical endurance: AC250V/3A/5A/10A is more than 100,000 times;
6, degree of protection: IEC IP67;
7, properties of product meet IEC61058-1 standard.
The above record is merely the embodiment that utilizes this origination techniques content, anyly is familiar with modification, the variation that this creation of this art utilization is done, and all belongs to the claim of this creation opinion, and is not limited to embodiment announcement person.
