Single axis vibration switch

Abstract

A uniaxial vibration switch, comprising a shell unit, a free piece, an electrode, and an elastic conductor, the shell unit includes a first shell, and a shell combined with the first shell to cover A second casing defining a chamber, the first casing is a conductor, the second casing is an insulator, the free part is arranged in the chamber and is close to the first casing, and the electrode is in contact with the first casing. The first casing runs through the second casing in isolation, and the elastic conductor is arranged in the chamber and between the free member and the electrode, and is electrically connected to the first casing. When there is vibration, the free part can push the elastic conductor to contact the electrode along with the vibration, so that the electrode, the elastic conductor and the first casing are electrically connected to form a conductive path.

Description

【Technical Field】 [0001] The invention relates to a vibration switch, in particular to a single-axis vibration switch. 【Background technique】 [0002] Refer to figure 1 , 2 , Is a new type patent of the existing Taiwan, China No. 181432 "single-axis vibration switch". The single-axis vibration switch includes a housing unit 10, an elastic element 20, an electrode 30, and a free piece 40. [0003] The housing unit 10 includes a first housing 11 surrounding an axis I, and a second housing 12 combined with the first housing 11 to form a chamber 13. [0004] The first housing 11 is an electrical conductor, and has a first inner side 111 located in the chamber 13 and facing the second housing 12, and a first outer side 112 opposite to the first inner side 111, And a first electrode 113 protruding from the first outer surface 112. [0005] The second housing 12 has a second inner side surface 121 located in the chamber 13 and facing the first inner side surface 111, a second outer sid...

Problems solved by technology

[0010] However, during actual operation, the design of the above-mentioned uniaxial vibration switch still has shortcomings, so that improvement is necessary to make the overall quality better and more accurate. figure 2 It can be found that when in the conduction state, since the free member 40 is not fixedly connected with the elastic element 20, nor is the elastic element 20 and the metal sheet 123 fixedly connected, so the entire conduction path is through the electrode 30 and the free electrode 30. 40, the contact between the free member 40 and the elastic element 20, and the contact between the elastic element 20 and the metal sheet 123 are completed, forming a use state through which three contact points 101 are used to achieve conduction, and because it is through Multiple contact points 101 above a single contact point are used to complete the conduction state, so on the one hand, there are disadvantages of unstable signals and increased uncertainties during the conduction process; on the other hand, there are many conduction conditions, which require simultaneous Satisfying three contact points 101 can form conduction, which causes the disadvantage of slow response to vibration
