Description

Improved key switch

The utility model relates to a kind of key switch, particularly a kind ofly need not add the improved key switch that nut screws togather.

Industrial and commercial progressive numerous property goes up in society now, quality of the life improves thereupon, make on its key switch function and look for novelty day by day, consumption also grows with each passing day, key switch of using as the audio-visual equipment of household electrical appliances and automobile audio etc., right its manufacture of conventional keys switch, must expend considerable expense and man-hour, cause the production cost costliness, and do not meet the economic utility of a large amount of manufacturings, and key switching structure commonly used, as shown in Figure 1, be to be provided with a plurality of screw threads 70 in the shell body 30 of key switch own, and above shell body 30 a chimeric button 10, and be provided with a conducting strip 40 in button 10 lower ends, in the shell body 30 and insert the spring 20 of a compression, chimeric two conductive connecting pins 50 on the drain pan lid 60 of these shell body 30 belows, make its conducting strip 40 contact conductive connecting pins 50 through pressing keys, cause circuit to form the state of conducting, and be when making its key switch be embedded on the panel of home appliance, need key switch is placed on the panel of home appliance, and screwed with a nut 71 and to screw togather, its key switch closely is embedded on the panel.

So not only make and make that assembling is more time-consuming, outside the inconvenience, and this key switch and can't accord with actual demand on household electrical appliances now, the circuit articles for use equipment such as audio-visual, the utmost point is treated further improvement.

Main purpose of the present utility model is that a kind of improved key switch will be provided, and does not need to be screwed togather with nut the shell body of key switch, key switch itself closely is embedded on the panel of electrical home appliances uses.

Another purpose of the present utility model is that a kind of improved key switch will be provided, and can simplify its manufacturing and ease of assembly, allows user's use that is convenient to operation.

The purpose of this utility model is achieved in that

A kind of improved key switch, consist predominantly of a button, one spring, one shell body, one conducting strip, two conductive connecting pins and drain pan lid, it is characterized in that: be provided with a straight-bar under the button, and dwindle the straight-bar caliber at straight-bar bottom place, and the place is provided with a plurality of sawtooth trips that can make on the guidance panel that this key switch is embedded in home appliance easily in the middle of the shell body, and below the body of rod both sides of less caliber respectively be provided with a trip, and the middle hole that runs through that is made as of shell body, this spring is sleeved on the straight-bar of button, the button of this fit spring is placed in the aperture that shell body runs through, this button little straight pole section cover is should conducting strip, this conducting strip is the copper piece of a rounded flat and middle hollow out, these drain pan lid both sides respectively are provided with a trip hole, this two conductive connecting pin closely is entrenched in drain pan lid bottom, and this drain pan covers trip hole and the trip on the key switch shell body set up and closely fastens mutually.

A plurality of sawtooth trips of establishing on this shell body can be increased or be reduced the quantity of sawtooth trip according to the thickness of panel.

The utility model provides a kind of shell body that does not need to be screwed togather with the nut that adds key switch, the sawtooth trip that is provided with via key switch itself can closely chimericly be fixed on the guidance panel of home appliance, reach and make things convenient for manufacturers produce and manufacturing, and can reduce the purpose that the effective working that needn't waste and handled easily use.

The utility model is simple in structure, is that the screw thread that will often have changes over a plurality of sawtooth trips, key switch is embedded on the panel of electrical appliance, thereby makes things convenient for manufacturers produce and manufacturing, has improved production efficiency, and handled easily uses.

Further specify the technical solution of the utility model and embodiment below in conjunction with accompanying drawing.

Description of drawings:

Fig. 1 is the perspective exploded view of key switch commonly used;

Fig. 2 be the utility model key switch three-dimensional exploded view;

Fig. 3 is the cutaway view of the utility model key switch;

Fig. 4 is the three-dimensional combination figure of the utility model key switch.

See also Fig. 2, shown in 3, its primary structure is that a button 10 is arranged, be provided with a straight-bar 11 for 10 times in button, and dwindle the caliber of straight-bar 12 at straight-bar bottom place, and the place is provided with a plurality of sawtooth trips 32 in the middle of shell body 30, and below the body of rod both sides of less caliber respectively be provided with a trip 33, and the shell body 30 middle holes that run through that are provided with, one spring 20 is sleeved on the straight-bar of button, simultaneously the button 10 of fit spring 20 is placed in the aperture 31 that shell body 30 runs through, the little straight-bar of button this moment can overlap unification conducting strip 40 for 12 sections, its conducting strip 40 is the electric conductor of a rounded flat and middle hollow out, cover 60 both sides in drain pan and also respectively be provided with a trip hole 61, and two conductive connecting pins 50 closely are entrenched in drain pan cover 60 bottoms, at last, trip hole 61 and the trip on the key switch shell body 30 33 set up on the drain pan lid 60 are closely fastened mutually, by a plurality of sawtooth trips 32 set on this key switch shell body 30, key switch can be embedded in easily on the guidance panel of home appliance used.

In sum, its disclosed improved key switch, a kind of shell body that does not need to be screwed togather with nut key switch is provided, and key switch itself closely is embedded on the panel of home appliance use, the effect of its enhancement has been had advance and practicality more during utilization, and the social resources that avoid waste, and then implement the patent requirement of environmental protection; But the above, it only is of the present utility model one preferable enforcement example, when can not with as limiting the scope that the utility model is implemented, all equalizations of being done according to the utility model claim change or modify, must belong in the scope that the utility model contains the existing utility application that in accordance with the law proposes.
