Description

Technical Field

[0001] The utility model relates to an electronic switch accessory, in particular to a pot reed for triggering conduction. Background Art

[0002] In various electronic switches, such as touch switches and micro switches, pot reeds are commonly used as triggering components. The key presses the top of the pot reed to elastically deform it, and it contacts the matching circuit contacts downwards for conduction. It has stable elasticity and a good feel. However, existing pot reeds are generally thin pot cover shapes. After elastic deformation, the top arc surface faces downwards, and the contact with the matching circuit contacts is a single point contact. Not only is the contact area too small, but the contact point is also smooth. During production assembly or use, if there are trace debris and foreign matter attached to the switch contact position, it can easily lead to poor contact, which directly affects the normal conduction control of the switch. Summary of the invention

[0003] In view of the deficiencies in the prior art, the utility model provides a pot reed with high conductivity and reliable conductive contact.

[0004] The utility model comprises a thin pot cover-shaped elastic pressing part, a supporting part is arranged around the elastic pressing part, a through hole is arranged in the elastic pressing part, and the lower edge of the through hole serves as a conductive deformation contact part.

[0005] The structure of the utility model is ingenious and reasonable. The lower edge of the through hole is used as the conductive deformation contact part. After the elastic pressing part is pressed down and elastically deformed, the lower edge of the through hole and the matching circuit contact are in line contact or multi-point contact, and the conductive contact is sufficient, and the reliability is greatly improved, ensuring the normal use and control of the switch. In addition, the lower edge of the through hole will have wrinkles and protrusions when it is elastically deformed downward, which has a certain puncture effect. Even if there is a trace amount of debris or foreign matter below, the wrinkles and protrusions can push away or penetrate the debris to ensure conductive contact.

[0006] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 4 It is another schematic diagram of the embodiment. Implementation

[0011] like Figures 1 to 3 As shown, the elastic pressing portion 1 is in the shape of a thin pan cover, a supporting portion 2 is arranged around the elastic pressing portion 1, a through hole 3 is arranged in the elastic pressing portion 1, and the lower edge of the through hole 3 serves as a conductive deformation contact portion. The through hole 3 can be arranged in the central area of ​​the elastic pressing portion 1, that is, where the elastic deformation is obvious, so that the lower edge of the through hole 3 is more fully conductively contacted with the matching circuit contact.

[0012] When the elastic pressing part 1 is pressed down, the elastic pressing part 1 and the supporting part 2 are deformed, and the lower edge of the through hole 3 is also deformed and makes line contact or multi-point contact with the matching circuit contact to achieve functional conduction. When the pressing stops, the elastic pressing part 1 and the supporting part 2 are lifted up and reset under the action of their own deformation elastic force, and the circuit contact is disconnected.

[0013] The support part 2 of this embodiment is composed of a plurality of support legs, and a bending area 4 is provided at the end of each support leg, so that the support is stable and the deformation elasticity is stronger. Figure 4 As shown, the support portion 2 is composed of an integral platform, and a plurality of concave areas 5 are arranged on the edges of the integral platform to also provide stable support.
