Long-life travel switch capable of outputting high positive force

Abstract

The invention discloses a long-life travel switch capable of outputting a high positive force, which comprises a shell, a terminal and a rear plug, wherein the terminal comprises a positive electrodeterminal and a negative electrode terminal which are arranged side by side, both the positive electrode terminal and the negative electrode terminal comprise a contact arc, a double-arc structure anda positioning plate, the double-arc structure comprises a large arc and a small arc, and the contact arc, the large arc, the small arc and the positioning plane are sequentially connected; the shell is provided with positioning slots and an assembling hole; the terminal is loaded into the shell, the contact arcs penetrate out of the front end of the shell, and the positioning planes are fixedly connected with the fixing slots respectively; and the rear plug is loaded into the assembling hole and used for fixing the terminal. The long-life travel switch can finally ensure that the single terminal can output a high positive force and is long in life through effectively combining the high hardness and high elasticity of the terminal material and the double-arc structure.

Description

technical field [0001] The invention relates to an intelligent instrument and various measuring instruments requiring batteries, in particular to a travel switch capable of outputting high positive force and long service life. Background technique [0002] The normal force output by a single terminal of the conventional limit switch design is low. Under the action of low positive force, the contact arc of the limit switch will not be able to contact the battery box in the working environment with vibration. Poor contact occurs due to contact with the polarity terminals. In addition, the terminal material does not have good stamping performance, or even if the terminal material has good stamping performance, the terminal has relatively high hardness before production, which has a great influence on the wear of the mold. Contents of the invention [0003] In order to solve the defects in the prior art, the present invention provides a travel switch capable of outputting hig...
