Description
Technical field
The utility model belongs to electronic product switch, particularly a kind of water proof type touch-switch.
Background technology
Touch-switch has the light and handy characteristic of volume, is applicable on the electronic products such as office electronic apparatus, control panel, telecommunication apparatus, electronic measurements, consumer-elcetronics devices and amusement equipment.
As shown in Figure 4, existing touch-switch mainly comprises body a, metal clips b, pressing piece c, shell d and pad e.
The both sides of body a are respectively equipped with projection a1, are provided with central contact a2 and side contact a3 in the body a, and the below of body a is provided with respectively two pin a4 that join with central contact a2 and side contact a3.
Metal clips b covers and is arranged at the end face that body a goes up central contact a2 and side contact a3, and the outer rim of metal clips b contacts with side contact a3.
Pressing piece c is arranged at the end face of metal clips b.
Shell d is arranged at the body a outside, and shell d both sides are provided with button hole d1 corresponding with body a upper protruding block a1 and that fasten, and the center of top of shell d is provided with opening d2.
Pad e is arranged between body a and the shell d.
During use, after the user was pushed downwards by pressing piece c top, the central part of metal clips b bottom surface can contact with central contact a2, and central contact a2 and side contact a3 are able to via the contact of metal clips b two pin a4 to be produced and electrically conduct; After user's hand left pressing piece c, metal clips b understood resilience and separates with central contact a2, makes two pin a4 be off-state, so, was had the effect of switch.
Only not sealing fully of the outside of metal clips b, central contact a2 and side contact a3 in the existing touch-switch, therefore, liquid can be flowed in the body a by between the opening d2 of pressing piece c and shell d and the slit between metal clips b and the body a, cause short circuit between central contact a2 and the side contact a3, thereby can't keep stable contact and good insulation performance characteristic; And the body a of existing touch-switch and metal clips b wear out and contact corrosion when placing wet environment can quicken contact, and finally damaged because of contact point loses efficacy because of not sealing fully.
Summary of the invention
The water proof type touch-switch that the purpose of this utility model provides a kind of good water-proof effect, increases the service life.
The utility model comprises body, metal clips, waterproof gasket, locating outer frame, pressing piece and shell; Be provided with central contact and side contact in the body, the bottom of body is provided with the pin that is connected with central contact and side contact respectively, and the body both sides are respectively equipped with projection; Metal clips covers the end face be arranged at central contact and side contact on the body, and the outer rim of metal clips contacts with the side contact; Waterproof gasket is arranged at the end face of body and metal clips; Locating outer frame is arranged at the waterproof gasket end face, and locating outer frame is octangle; Pressing piece is arranged at the locating outer frame inner edge and extends upward; Shell is arranged at outside body, locating outer frame and the pressing piece, and the end face of shell is provided with correspondence and is sheathed on opening on the pressing piece, and the shell both sides are respectively equipped with correspondence and are sticked in button hole on the projection.
Wherein:
Bodies top is provided with four positioning convex column; Shell is provided with correspondence and is sheathed on four positional punches on four positioning convex column of bodies top.
The pressing piece bottom is provided with base corresponding with the locating outer frame inner edge and the embedding group.
Because the utility model comprises body, metal clips, waterproof gasket, locating outer frame, pressing piece and shell; Be provided with central contact and side contact in the body, the bottom of body is provided with the pin that is connected with central contact and side contact respectively, and the body both sides are respectively equipped with projection; Metal clips covers the end face be arranged at central contact and side contact on the body, and the outer rim of metal clips contacts with the side contact; Waterproof gasket is arranged at the end face of body and metal clips; Locating outer frame is arranged at the waterproof gasket end face, and locating outer frame is octangle; Pressing piece is arranged at the locating outer frame inner edge and extends upward; Shell is arranged at outside body, locating outer frame and the pressing piece, and the end face of shell is provided with correspondence and is sheathed on opening on the pressing piece, and the shell both sides are respectively equipped with correspondence and are sticked in button hole on the projection.During use, after the user is pushed downwards by the pressing piece top, press down after making the pressing piece top slight stressed, the bottom surface of pressing piece can see through waterproof gasket metal clips is pressed down, after metal clips is pressed down, metal clips bottom central part position can contact with central contact, makes central contact and side contact that two pins are produced and electrically conducts.After user's hand left pressing piece, metal clips can make progress resilience and separate with central contact, makes two pins be returned to the state of not conducting, so, just reached the effect of switch; The waterproof gasket that is arranged at body and metal clips end face presses solidly and makes by locating outer frame and exists without any the space between waterproof gasket and the body, so, liquid and aqueous vapor can't enter in the body, thereby can effectively avoid short circuit, the aging situation that reaches contact corrosion of contact that the effect that reaches waterproof and increase the service life takes place.Good water-proof effect not only, and increase the service life, thereby reach the purpose of this utility model.
