Description

Waterproof micro switch

Technical field

The utility model belongs to microswitch technical field, especially a kind of waterproof micro switch.

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, is covered with shell, outside have a kind of switch of drive rod because contact spacing of its switch is smaller, Therefore named microswitch, is called sensitive switch.Waterproof micro switch is one kind of microswitch, and waterproof fine motion in the prior art is opened Closing includes shell, cover board and button, by after shell is fixedly connected with cover board junction carry out dispensing play it is certain anti- Water effect, but play and be very easy to aging and abrasion at the dispensing of waterproof action, so that the water-proof function of microswitch is failed, makes At security risk.

Utility model content

It is a kind of than prior art better tightness, waterproof that in order to overcome the deficiencies of the prior art, the utility model provides Better effect, safer waterproof micro switch.

To achieve the goals above, the technical solution adopted in the utility model is: a kind of waterproof micro switch, including by The shell that one shell and second shell are spliced to form, first shell and second shell stitching portion form cavity, are provided in cavity Conductive component, hull outside are provided with the button worn into cavity, the stitching portion one of the first shell itself and second shell It is body formed to have the flange around cavity setting, the groove with first shell cooperation grafting is provided in second shell, it is described It is provided with the first welding bar that can be offseted when first shell and second shell are spliced with groove inner wall on flange, described first Welding bar is formed in groove inner wall by ultrasonic bonding and is sealed.

Using the above scheme, relatively solid between first shell and second shell by first making flange grafting in a groove It is fixed, ultrasonic welding process is recycled, the first welding bar being arranged on flange is melted, the first welding bar is enable to fuse It, can be by the stitching portion of first shell and second shell by forming stable sealing after welding on groove inner wall.This is practical new Type reduces external abrasion, and will not influence product beauty, keeps the sealing performance of microswitch more preferable, waterproof effect more preferably, Using safer.

As the further setting of the utility model, first welding bar, which corresponds to, contacts conductive position in conductive component It is arranged jagged.

Using the above scheme, prevent the first welding bar from contacting conduction in conductive component in fusion process favorite outer leak into Position, the phenomenon that avoiding microswitch poor contact, improve product qualification rate.

As the further setting of the utility model, one end that the button is placed in hull outside is arranged with button cap, institute It states hull outside corresponding button and wears position and be provided with pit, the button is threaded through in pit, and the button cap includes socket Socket part on button and the sealing being inlaid in pit, socket of the sealing around socket part is arranged, described It is provided with the ring cowling for being encapsulated in sealing in pit on pit, the second welding is provided between the pit and ring cowling Muscle, second welding bar are arranged close to pit edge and pass through ultrasonic bonding in the edge of pit.

Using the above scheme, a button cap is arranged to movable button, the socket part of button cap can carry out button Cladding protection, the sealing for being looped around socket are inlaid in pit, certain sealing function are played to pit, then pass through ring cowling First by both seals in pit, then by ultrasonic bonding by the second welding bar soldering on ring cowling pit surrounding Edge, so that the ring cowling after welding engages with pit and plays the role of to pit abundant that waterproof sealing, the second welding bar are leaned on Nearly pit edge setting the second welding bar can be enable abundant be melted in the edge of pit, will not be corrupted to by Button cap.

As the further setting of the utility model, the cross sectional shape of first welding bar and the second welding bar is triangle Shape.

Using the above scheme, triangular shape is to be able to make to fuse quicker, raising production during ultrasonic bonding Efficiency.

As the further setting of the utility model, the lateral wall of the first shell is provided with sliding slot, on the sliding slot It is provided with clamping block, the second shell is provided with the linking arm with sliding slot cooperation, is provided on the linking arm and clamping block Cooperate the blocked hole of clamping, is provided on the clamping block when linking arm slides into sliding slot convenient for leading clamping block slide-in blocked hole To inclined-plane.

Using the above scheme, the clamping engagement between blocked hole and clamping block can prevent biggish external force from making first shell It is separated with second shell, to influence its waterproof performance, further increases the reliability of product, before welding progress, Clamping block and being engaged by clamping for blocked hole can keep opposite stabilization convenient for the maintenance of first shell when welding and second shell, Mutually without departing from keeping welding effect more preferable.

The utility model is further described with reference to the accompanying drawing.
