Description

Switch fastens the package assembly improvement

The utility model relates to a kind of electric switch in the essential electronic element, refer in particular to be incorporated into and be assembled in Switch main body again after the Switch main body buckling piece is independently made with preferable elastomeric material, make it except having better fastening intensity, more can when damaging, buckling piece change separately, with the structure-improved that reduces cost.

Conventional press key type switch as shown in Figure 4, its every electronic component all is coated in the Switch main body, only expose outside the Switch main body A with the conducting strip B that is connected in internal circuit board by strong, when switch is installed on specific hole, this conducting strip B is arranged in gives fixed electric wire, and control it and whether switch on by pushing by being good for; In addition, be fixed in the set hole of switch base (not shown) in order to make Switch main body A combination, it is provided with the buckling piece A1 that has elasticity and outwards be inclination respectively in outside relative two sides of Switch main body A, this buckling body A1 is that two side one by Switch main body A extend moulding and make, the upper end of this buckling piece A1 is formed＜shape, use when making Switch main body A be inserted in the hole, successfully be inserted in the lower end that can make Switch main body A be reduced size, and make the buckling piece A1 that is the inclined-plane also be inserted in hole; This Switch main body A is when being inserted in hole, and buckling piece A1 can be oppressed and elastic compression, crosses the hole rear until the earclip A11 of buckling piece A1 upper end and can outwards flick and fasten the periphery of hole and fix; Simultaneously, the element of being located in the Switch main body is that one is coated on inside when making Switch main body.

Yet but there is columns item shortcoming down at least in above-mentioned ordinary tap structure:

One, its buckling piece is to make with Switch main body is one-body molded, so used material must be identical, but because of buckling piece be a kind of spring secures rail to sleeper, after repeatedly back and forth pushing effect, may fracture, in case during a buckling piece fracture, promptly whole switch all must be changed, very waste seems.

Two, because relevant element is coated in the Switch main body all one-body moldedly,, change and must will put in order the group switch so when inner element has fault, also can't renew at this element, quite uneconomical.

The purpose of this utility model is to propose a kind of Switch main body of mainly being made up of Switch main body, lid and buckling piece and fastens package assembly, and it is not only durable, and maintenance is easy, and can reduce manufacturing cost, thereby has solved the existing in prior technology problem.

The technical scheme that the utility model adopted is, it mainly is made up of Switch main body, lid and buckling piece, this Switch main body is provided with an opening, for the related elements of packing into, outside relative two sides at this Switch main body are respectively equipped with a caulking groove, in this two caulking groove, be embedded a buckling piece independently respectively, this buckling piece is incorporated into have suitable elasticity behind the Switch main body and can be fastened on specific hole, behind this buckling piece assembling caulking groove, be covered in opening with cover plate again and shelter from buckling piece and drop out avoiding.

Said caulking groove, has a button edge in its inboard, the outside inner face of this button edge is formed with an inclined-plane relatively, this buckling piece is to be made as to have an extension board, the end limit of this extension board is provided with a clasp, use and this extension board can be matched with above-mentioned caulking groove, the lateral surface closing that makes extension board is in above-mentioned inclined-plane and inclined, and fixes by clasp is fastened on edge.

Advantage of the present utility model is:

1, its buckling piece is independently to make respectively with Switch main body, so must can adopt the material that has more elasticity and intensity by stressed buckling piece, thereby the durability of enhanced products, in case and buckling piece when fracture in the future, lid can be taken apart the back is changed at this buckling piece, remainder still can continue to keep use, so can reduce cost.

2, owing to relevant element covers lid fixing the composition after all being installed in the Switch main body again, so when inner element has fault, also can the lid breakdown be upgraded at out of order element by particular tool, do not need to put in order the group switch and change, than the tool economy.

Further specify preferred embodiment of the present utility model in conjunction with above-mentioned each accompanying drawing now.As depicted in figs. 1 and 2, Switch main body of the present utility model (1) is provided with an opening for the relevant electronic component of packing into, and other is provided with a lid (2) for being covered in this opening; Button (12) and conducting strip (13) are exposed to the upper and lower of Switch main body (1) respectively, make this conducting strip (13) establish electric wire for connecing; Outside relative two sides of this Switch main body (1) are respectively equipped with a caulking groove (1), this caulking groove (11) is to be provided with a button edge (111) in its inboard, outside inner face with respect to this button edge (111) is formed with an inclined-plane (112), the independent in addition buckling piece of making (3) is the elastic component made from the material with preferable elasticity and intensity, it is to form to have an extension board (31), the limit, lower end of this extension board (31) is provided with a clasp 311, the upper end of this extension board (31) is integrally formed with an earclip (32) that is "＜" shape, forms matsurface at the ramp (321) of this "＜" shape.

By the structure of this caulking groove (11) with buckling piece (3), when cover plate (2) is not covered in the opening of Switch main body (1), the extension board (31) of this buckling piece (3) can be slipped in caulking groove (11) along the side of caulking groove (11), the lateral surface closing that makes extension board (31) is in the inclined-plane (112) and inclined, and buckling piece (3) is fixed in caulking groove (11) by clasp (311) is fastened on edge (111), as shown in Figure 3, again lid (2) is covered in behind the opening of Switch main body (1) to pass and gives the hole of being located at lid (2) and Switch main body (1) and fixing and combine with fixing pin; Inclined and make it have elasticity in conjunction with the back by this buckling piece (3), when Switch main body (1) was inserted in the hole of switch base, successfully be inserted in the lower end that can make Switch main body (1) be reduced size, and make the buckling piece (3) that is the inclined-plane also be inserted in hole; This Switch main body (1) is when being inserted in hole, and buckling piece (3) can be oppressed and elastic compression, crosses the hole rear until the earclip (32) of buckling piece (3) upper end and can outwards flick and fasten the periphery of hole and fix.

The above only is in order to explain preferred embodiment of the present utility model; be not that attempt is done any pro forma restriction to the utility model according to this; so; all have in that identical creation spirit is following do relevant any modification of the present utility model or change, all should be included in the claim protection range of the present utility model.
