Abstract
The present invention provides a structure for keeping a key of a casing of an electric appliance without the need of complex operation or members or the guarantee of space larger than the volume of the key in the casing. A key body 10 is embedded in an embedding section 3 and then is fixed at a clamping section 6, a shaft body 11 is embedded in a guide opening section 5 so as to keep a key 9 by corresponding to a casing 1, and the key 9 can not be protruded outside a casing 10 by the contact of a flange section 12 and the peripheral section of the guide opening section 5.
Description
The present invention relates to the structure for keeping key of casing for electric appliances, be used for being provided with and keep on the casing for electric appliances of the key switch that is electrically connected usefulness making this push-button switch carry out the button of ON/OFF action in inside.
When remaining on button on the casing for electric appliances in the past, from above-mentioned enclosure interior button is installed, and push-button switch is arranged on the protuberance consistent location with this button, utilize between the molded product of synthetic resin depositedly mutually again, keep above-mentioned button not come off from above-mentioned housing.
The problem that above-mentioned existing maintenance structure exists is to keep above-mentioned button to need complicated operation or parts, and not only to prevent from above-mentioned push-button switch to be added excessive stress when above-mentioned outside is pushed, above-mentioned button is not protruded from outside the above-mentioned housing, so need around above-mentioned button, flange part be set, need guarantee in above-mentioned housing that for this reason the space is bigger than above-mentioned button volume.
The present invention is according to the problems referred to above, and purpose is to provide a kind of structure for keeping key of casing for electric appliances, need not complicated operation or parts when remaining on button on the housing, and needn't guarantee in housing that the space is bigger than button volume.
To achieve these goals, the structure for keeping key of casing for electric appliances of the present invention is used for being provided with on the casing for electric appliances of the push-button switch that is electrically connected usefulness in inside, be kept for the button of this push-button switch of switch, above-mentioned button stretches out the axis body of a minor diameter at the inner surface of its key body, simultaneously, in the end of this axis body flange is set; Above-mentioned housing has the fitting portion, dependence the chimeric of above-mentioned axis body that embed above-mentioned key body from the outside this axis body leading section is determined at the locational clamping part of leading oral area and clamping above-mentioned key body corresponding with above-mentioned push-button switch; Above-mentioned key body is embedded above-mentioned fitting portion, be fixed in above-mentioned clamping part simultaneously, and above-mentioned axis body and the above-mentioned oral area of leading is chimeric, thus above-mentioned relatively housing maintains above-mentioned button, utilize above-mentioned flange part to lead contacting of oral area periphery, prevent that above-mentioned button from protruding from outside the above-mentioned housing with above-mentioned.
To be fixed in clamping part behind the key body embedding fitting portion, and axis body is embedded, thereby button is remained on the housing.Therefore, required in the past complex job or component no longer need.In addition, utilize the flange part of axis body end to contact with leading oral area on every side, button does not protrude from outside the housing, and needn't keep in housing than the bulky space of button.
Embodiments of the invention are described below with reference to the accompanying drawings.
Fig. 1 is an exploded perspective view, and the structure for keeping key of the casing for electric appliances of the present invention the 1st embodiment is shown.
Fig. 2 is an exploded perspective view, and the structure for keeping key of the casing for electric appliances of the present invention the 2nd embodiment is shown.
Fig. 1 is an exploded perspective view, and the structure for keeping key of the casing for electric appliances of the present invention the 1st embodiment is shown, wherein, the 1st, casing for electric appliances is made down the rectangle of bottom opening, and this dress cap 2 of going to the bottom.Housing 1 vertically on position in the middle of roughly, traverse upper bottom surface and leading flank, form the fitting portion 3 of nick shaped.At fitting portion 3, housing 1 inner past leading flank level is stretched out a convex surface 4, and forms one with housing 1.
Form on this convex surface 4 and lead oral area 5, it is made of the slotted hole that leads to the below from above-mentioned convex surface top.Form the clamping part 6 that constitutes by pawl 6a, 6b in upper end two examples of leading oral area 5.
The push-button switch 7 that is electrically connected usefulness is set in housing 1.This push-button switch 7 is fixed on the position of printed circuit board (PCB) 8 upper surface substantial middle, and in the housing 1 of packing into, thereby the operation by button 7a realizes switch motion.
Push-button switch 7 relies on button 9 to carry out switch motion.Button 9 has the key body 10 that is made of horizontal plane 10a and vertical plane 10b.Be provided with at the position of the horizontal plane 10a of key body 10 inner surface substantial middle and stretch axis body 11 under the minor diameter, and form one with key body 10.Form flange part 12 again with this one in axis body 11 bottoms.
The button 9 of Gou Chenging remains on the housing 1 as described below like this.
Like this, button 9 remains on the housing 1, and under this state, button 9 will be towards top when floating and since flange part 12 lead oral area 5 peripheries touch convex surface 4 below, button 9 can not protrude (non-rising) from housing 1 top.
Like this, remain on button 9 on the housing 1 by pressing operation, the front end pressing button 7a of axis body 11, thus make push-button switch 7 carry out switch motion.
According to Fig. 2 the 2nd embodiment of the present invention is described below.
With the identical part of above-mentioned the 1st embodiment, be marked with identical symbol among the figure in the present embodiment.
Present embodiment and the 1st embodiment difference are, the clamping part 13 that constitutes by small-diameter hole in the root edges setting of convex surface 4, to substitute the clamping part 6 that constitutes by pawl 6a, 6b, at the horizontal plane 10a of key body 10 inner surface the protruding button 14 chimeric with clamping part 13 is set integratedly again.So, utilize protruding button 14 to embed in the clamping part 13, button 9 can not deviate to a side from housing 1.
Present embodiment is compared with the 1st embodiment, can maintain button 9 under bigger external force.
Present embodiment other structure and the effect identical with the 1st embodiment, it illustrates omission.
As mentioned above, according to the maintenance structure of casing for electric appliances button of the present invention, the key body remains in the clamping part after embedding in the fitting portion, and axis body is also chimeric, by this button is maintained with respect to housing, thereby no longer need to keep necessary complex job of button or parts in the past.In addition, utilize the flange part of axis body front end to contact with leading the oral area periphery, button can not protrude to outside, and enclosure interior needn't keep than the bulky space of button.
