Further, described pin is SMD, and described pin and corresponding edge stationary contact are structure as a whole.
Further, described cover plate and base form a cavity, the geometric center place of described cover plate offer withThe first through hole that shift knob coordinates, a part for described contact flat spring and shift knob is positioned at cavity, instituteAnother part of stating shift knob passes described the first through hole and exposes cover plate, and described shift knob exposes cover plateThe rounded column of part or kidney-shaped column.
Further, the bottom of described base is provided with base plate, and described base plate and base are fastened and connected, the described endThe periphery of plate has four breach, has the second through hole and touch for receiving described electricity between described breach and basePoint inserts.
The beneficial effects of the utility model are:
A kind of touch-switch of the present utility model by being provided with several boss, institute in a side periphery of baseThe bottom of stating boss is provided with draw-in groove, and described cover plate is fixed in draw-in groove, simple in structure, volume is little, makesThe overall dimensions compactness of switch, installs and takes up room littlely, arranges more flexibly, and installs firmly, is easy toOperation, performance is very reliable.
Brief description of the drawings
Fig. 1 is the stereogram of a kind of touch-switch of the present utility model;
Fig. 2 is the upward view of touch-switch shown in Fig. 1.
Detailed description of the invention
Below with reference to drawings and Examples, the utility model is described further, but should limit with thisMake protection domain of the present utility model.
For convenience of description and understand the technical solution of the utility model, the noun of locality that below explanation is usedThe orientation of all being shown with accompanying drawing is as the criterion.
As depicted in figs. 1 and 2, a kind of touch-switch of the present utility model, comprises base 1 and is arranged onElectric contact inserts 2 on base 1, contact flat spring (not shown), shift knob 3, cover plate 4 andBase plate 5.
Described base 1 is square hollow column and upper and lower both ends open, and the upper end of base 1 is provided with cover plate 4,The lower end of base 1 is provided with base plate 5. Described cover plate 4, base 1 and base plate 5 form a cavity, described lidThe geometric center place of plate 4 offers the first through hole 41 coordinating with shift knob 3, described contact flat spring and openingThe bottom of closing button 3 is positioned at cavity, and the top of described shift knob 3 through described the first through hole 41 alsoExpose cover plate 4, the rounded column of part or kidney-shaped column that described shift knob 3 exposes cover plate 4.
One side periphery of described base 1 is provided with several boss 11, and the bottom of described boss 11 is provided with cardGroove 111, described cover plate 4 is fixed in draw-in groove 111. In the present embodiment, open the upper end of base 1Mouth and only four angles place are provided with installation end face, on described each installation end face, are respectively equipped with boss 11. Boss11 completely do not cover end face are installed, and that is to say, end face is installed and is had and expose near a side of shift knob 3Part.
When installation, as long as cover plate 4 is aimed to base 1 and pressed downwards until cover plate 4 is fastened on draw-in groove 111In, can realize being connected and fixed of cover plate 4 and base 1, the exposed parts of the installation end face of base 1 can be rightCover plate 4 carries out mounting limit, simple and compact for structure, volume is little, and firm, easy operating are installed. Described protrudingPlatform 11 is plane or cambered surface near a side of shift knob 3, and the junction of cover plate 4 is for to mate with boss 11Linear pattern or arc, when assembling, cover plate 4 and boss 11 are easy to by interference fit.
Described contact flat spring and shift knob 3 are by interference fit, described in the bottom of described shift knob 3 is arranged onOn contact flat spring, described contact flat spring is arranged on electric contact inserts 2.
Described electric contact inserts 2 comprises center stationary contact and four edge stationary contacts, and four edge stationary contacts divide, with four corresponding pin 21 conductings, described pin 21 is not through outside the bottom protuberate basic unit 1 of base 1.The middle part of described contact flat spring opens and closes and contacts with center stationary contact elasticity, the periphery of described contact flat spring and edgeStationary contact contact laminating. In the present embodiment, described pin 21 is SMD, but is not limited to SMDly also canBeing direct insertion. Described pin 21 and corresponding edge stationary contact are structure as a whole.
The bottom of described base 1 is provided with base plate 5, and described base plate 5 and base 1 are fastened and connected. Described electricity touchesPoint inserts 2 is arranged on base plate 5. The Si Jiaochu of described base plate 5 is respectively equipped with breach, described breach and the endBetween seat 1, there is the second through hole for receiving described pin 21.
When push switch, also press shift knob 3 down, shift knob 3 is forced the surface of face contact shell fragmentDistortion downwards, the middle part of contact flat spring contacts with center stationary contact fast, makes switch conduction. Remove and pressAfter external force, shift knob 3 elastic recoverys, contact flat spring also produces bounce-back under the elastic force effect of self, fromOpen center stationary contact, switch disconnects. Contact flat spring can be designed to the series of different elastic force and different coating, logicalCross touching operating physical force and the contact resistance of changing contact flat spring and can change switch, easy to adjust.
