Embodiment 1

[0029] Such as Figure 1-Figure 5 As mentioned above, the embodiment of the present invention provides a switch device, including a fixing frame 1 , a circuit board assembly 2 , a pressing plate 3 , a bracket 4 , a panel 5 , a button 6 and a switch 7 .

[0030] Wherein, the fixed frame 1 is provided with a cavity 11, the cavity 11 has an opening, the circuit board assembly 2 is arranged in the cavity 11, and the circuit board assembly 2 is fixed in the cavity 11 by the pressing plate 3, the switch 7 is installed on the circuit On the plate assembly 2, and the switch 7 is located at the opening of the cavity 11, since the switch 7 needs to be exposed for pressing, a via hole 31 for avoiding the opening is also provided in the middle of the pressing plate 3, and the switch 7 extends from the via hole 31. out. The panel 5 is installed at the opening of the cavity 11 of the fixed frame 1, and is used to cover the fixed frame 1, and can also limit the position of the bracket 4. Th...

Embodiment 2

[0045] Such as image 3 , Figure 5 As shown, in an optional embodiment of the present invention, a boss 421 is provided on the surface of the trigger portion 42 opposite to the switch 7 , and the boss 421 is adapted to the switch 7 .

[0046] The switch 7 is arranged in the middle of the circuit board assembly 2 , and similarly, the boss 421 is arranged in the middle of the trigger part 42 . The shapes and sizes of the two can be approximately the same, and it is also feasible that the surface area of ​​the boss 421 is larger or smaller than the surface area of ​​the switch 7 , which is not limited here.

[0047] After the user presses the button 6, the pressing part 43 and the trigger part 42 are driven to move down. As the trigger part 42 moves down, the boss 421 and the switch 7 interfere with each other, and the switch 7 is pressed to realize the conduction or disconnection of the circuit.

[0048] Due to the mutual cooperation between the boss 421 and the switch 7, it...

Embodiment 3

[0051] Such as Figure 2-Figure 5 As shown, in an optional embodiment of the present invention, the pressing portion 43 is Z-shaped, formed by integrally extending and bending the edge of the triggering portion 42 . The plane of the free end of the Z-shaped pressing portion 43 is higher than the plane of the triggering portion 42 , which can well support the button 6 . And the Z-shaped structure has good rigidity, and can support the button 6 for a long time when there is no external force, and can also be quickly reset after the external force, preventing the pressing part 43 from being unable to drive the trigger part due to fatigue failure caused by pressing deformation 42 moves.

[0052] Furthermore, reinforcing ribs are provided at the bends of the pressing portion 43 . The ribs can further improve the rigidity of the pressing portion 43 , preventing the pressing portion 43 from being unable to drive the triggering portion 42 to move due to fatigue failure caused by pre...

Abstract

The invention is applicable to the technical field of electrical connection, and particularly relates to a switching device, which comprises a fixed frame provided with a cavity provided with an opening, and a switch arranged at the opening of the cavity; the bracket is arranged at the opening of the cavity and is arranged on one side, deviating from the cavity, of the switch; the support comprises a fixed part, a triggering part arranged right opposite to the switch and a plurality of abutting parts which extend out in the plane direction of the triggering part and are arranged in a divergingmode. A gap is formed between the abutting part and the fixed part, the abutting part and the fixed part are elastically connected into a whole, and the triggering part moves under pressure and triggers on-off of the switch; the free end of the pressing part tilts towards the direction deviating from the switch; and the key is arranged on one side, deviating from the switch, of the bracket and issupported by the free end of the pressing part. The switch device is simple and reliable in overall structure, no dead angle exists on the surface of the key, and on-off of the circuit board can be controlled by pressing any position on the surface of the key.

Description

technical field [0001] The invention is applicable to the technical field of electrical connection, and in particular relates to a switch device. Background technique [0002] With the improvement of people's living standards, the wide application of electronic products and the popularization of the Internet, the functions of switches and sockets have gradually developed from traditional mechanical switches to electronic smart homes. In recent years, smart switches are changing with each passing day, gradually replacing traditional ones Mechanical switches have become an integral part of life. Among smart switch products, micro switches are widely used because of their simple structure, long sensitivity, long life and small size. [0003] The micro switch is usually provided with at least one contact point under the key panel, and when the user presses the key panel, the contact is triggered to open or close the circuit. However, at present, the micro switch cannot trigger...
