Description
Technical field
The present invention relates to a kind of electric switch, be specifically related to a kind of Downwards-pushing-typower power switch.
Background technology
Switch refers to that one can make open circuit, makes current interruptions or make it flow to the electronic component of other circuit, can be divided into sensitive switch according to structure, ship type switch, toggle switch, toggle switch, push-button switch, key switch etc.The household electrical appliance such as television set, DVD, water dispenser mainly adopt ship type switch or push-button switch; There is a sheet metal existing rocker type switch inside, there is fulcrum of spring centre, spring swings on sheet metal, realize the moving contact of sheet metal and switching on and off of haptic element, in use procedure, spring is all in compression state regardless of under the state of still closing at switch open, long distortion makes spring easily tired, causes switch short for useful life.
Push-button switch utilizes button to promote transmission mechanism, and moving contact and fixed contact are opened by on-off and the switch of realizing circuit changing-over.The complicated mechanism of existing push-button switch, assemble about a switch probably needs to expend half an hour, on-off action all can cause moving contact to clash into haptic element each time in use, haptic element horizontal looseness can be caused, long-time use can cause haptic element to be shifted, switch loose contact, and useful life is shorter; In addition, the point of application of existing push-button switch is positioned at the top of transmission mechanism, needs to expend larger power and just can press the button, use inconvenience during use.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of Downwards-pushing-typower power switch, and structure is simple, easy to assembly, reduces production cost, laborsaving and the life-span is long during use.
The present invention is achieved through the following technical solutions:
A kind of Downwards-pushing-typower power switch, comprise housing, and be located at first, second haptic element of housing inner bottom part, also comprise to put in housing from housing side can do horizontal reciprocating movement, with the push rod of self-locking mechanism, the top of described housing is provided with the balance staff extended to housing bottom, described balance staff is socketed the spring with spring housing, one end that described push rod puts in described enclosure interior is connected with the bottom of described spring housing; The bottom of described spring housing offsets with the upper surface of the contact chip be arranged on described second haptic element; Described contact chip is provided with moving contact, and the upper surface correspondence position of described first haptic element is provided with fixed contact.
The further improvement project of the present invention is that the top of described housing is provided with opening, and described balance staff upper periphery is symmetrically arranged with card convex, and the draw-in groove that described card convex and described case top opening sidewalls are provided with is connected, and realizes the swing of balance staff.
Further improvement of the present invention scheme is, the downward projection of described card convex is between first, second haptic element.
Further improvement of the present invention scheme is, the link of described push rod and spring housing is provided with balance staff hole, and balance staff hole hoop is in the bottom of described spring housing.
Further improvement of the present invention scheme is, the side elevation of described contact chip is the arc that two ends are upturned, and described contact chip medium position is connected to the upper end of described second haptic element.
Further improvement of the present invention scheme is, at the bottom of the arc of described contact chip medium position, dual-side is provided with bayonet socket, and described second haptic element upper end correspondence position is provided with card column, both activity clampings.
Further improvement of the present invention scheme is, one end of described contact chip is provided with the platform of horizontal-extending, the other end is provided with limiting section to downward-extension, and described moving contact is fixing on the platform, and the end of described limiting section is a little less than at the bottom of the arc of contact chip.
Further improvement of the present invention scheme is, when described push rod is positioned at initial position, described balance staff is to end inclination formation first inclination angle, limiting section place on described contact chip, when described push rod puts in self-locking in described housing, described balance staff is to end inclination formation second inclination angle, moving contact place on described contact chip, and described first inclination angle is greater than described second inclination angle.
Further improvement of the present invention scheme is, when described first inclination angle is reached, the end of described limiting section props up housing bottom inwall; When described second inclination angle is reached, described moving contact and described fixed contact fit tightly.
Further improvement of the present invention scheme is, described housing upper cover is stamped cover plate.
Compared to the prior art, the present invention has the following advantages:
One, structure of the present invention is simple, push rod drives balance staff band moving contacting plate of vacillating now to the left, now to the right on contact chip to upwarp and move down, realize being switched on or switched off of moving contact and fixed contact, the kind of drive is reliable, parts are few, easy to assembly, reduce cost of material and production process, greatly improve the production efficiency of mains switch.
Two, the spring long service life of balance staff of the present invention, when push rod pushes in housing completely, switch connection, balance staff now slightly tilts to dynamic, fixed contact place end, spring on balance staff is in impaction state, ensure fitting tightly of dynamic, fixed contact, when push rod resets, balance staff tilts to this end to opposite side swing and then band moving contacting plate with push rod, now spring is in and is not squeezed or state that extruding force is less, delay the fatigue of spring, and then in use extend the useful life of spring.
Three, moving contact of the present invention is positioned at directly over fixed contact, fixed contact is extruded from top to bottom under the drive of transmission mechanism, the horizontal displacement of haptic element can not be caused, and then not easily loosen when ensureing stable uses of haptic element, the phenomenon of the incomplete generation loose contact of anti-stop, fixed contact contact.
