In order to achieve the above purpose, the utility model adopts the following technical scheme:
an elastic key device comprises a shell, a circuit board, a tact switch and an elastic key;
the circuit board is fixedly connected inside the shell, and the light welding leg of the light touch switch is connected on the circuit board;
the elastic key consists of a key cap, a fixed arm and a connecting rib, wherein two ends of the connecting rib are respectively connected with the key cap and the fixed arm, the free end of the fixed arm is fixedly connected with the inner side wall of the shell, the key cap is arranged right above the light touch switch, and the top of the key cap extends out of the shell from a yielding hole on the shell;
when the key cap of the elastic key is pressed, the key cap is contacted with the light touch switch, and when the key cap of the elastic key is released, the key cap is separated from the light touch switch.
Furthermore, the free end of the fixed arm is provided with a riveting hole, the inner side wall of the shell is correspondingly provided with a riveting column, and the riveting column and the riveting hole are connected into a whole through plastic thermal riveting.
Furthermore, a groove is formed in the bottom of the connecting rib.
Further, the depth of the groove is 1 mm.
Furthermore, arc transition is arranged at the corner of the bottom surface of the groove.
The utility model adopts the above technique, following beneficial effect has:
1. the elastic key does not need a silica gel cap, and can be directly arranged on the light-touch switch, so that the manufacturing cost of an electronic product is reduced;
2. the elastic key and the shell are in hot riveting by adopting plastic, so that the elastic key has the advantages of good insulation, corrosion resistance, firm positioning and fixing and convenience in assembly;
3. the connecting rib of the elastic key is provided with a groove, so that the resilience function of the elastic key is ensured, and in addition, the bottom of the groove is chamfered by an arc, so that stress concentration during pressing is prevented, and the service life is prolonged.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments;
fig. 1 is a schematic structural diagram of the present invention;
fig. 2 is a schematic sectional structure view of the elastic key of the present invention;
fig. 3 is a schematic top view of the elastic button of the present invention.
Detailed Description
In order to make the technical solution of the present invention more apparent, the present invention will be further described in detail with reference to the following examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in one of fig. 1 to 3, the elastic key device of the present invention includes a housing 4, a circuit board 1, a tact switch 2, and an elastic key 3;
the circuit board 1 is fixedly connected inside the shell 4, and a light welding pin of the tact switch 2 is connected on the circuit board 1;
the elastic key 3 consists of a key cap 31, a fixed arm 32 and a connecting rib 33, two ends of the connecting rib 33 are respectively connected with the key cap 31 and the fixed arm 32, the free end of the fixed arm 32 is fixedly connected with the inner side wall of the shell 4, the key cap 31 is arranged right above the tact switch 2, and the top of the key cap 31 extends out of the shell 4 from a yielding hole on the shell 4;
when pressing the button cap 31 of elastic key 3, press button cap 31 and dabbing the switch 2 contact, when loosening the button cap 31 of elastic key 3, press button cap 31 and dabbing the switch 2 separation, control dabbing the switch 2 through pressing elastic key 3, elastic key 3 can direct mount moreover on dabbing the switch 2, need not adopt the silica gel cap to guarantee elasticity.
The free end of the fixed arm 32 is provided with a riveting hole 34, the inner side wall of the shell 4 is correspondingly provided with a riveting column 41, and the riveting column 41 and the riveting hole 34 are connected into a whole through plastic thermal riveting. The elastic key 3 and the shell 4 are in hot riveting by adopting plastic, and compared with screw connection, the elastic key has the advantages of good insulation property, corrosion resistance, firm positioning and fixing and convenience and rapidness in assembly.
