Embodiment Construction

[0028] The present invention will be described in further detail below in conjunction with the accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0029] Such as Figure 1 to Figure 3 As shown, a novel magnetic proximity switch of the present invention includes a housing 1, the upper part of the housing 1 is provided with a moving magnet 2 that can move up and down, specifically, a sliding magnet 2 is provided in the housing 1. Slot 11, the moving magnet 2 can move up and down in the chute 11, in order to make the moving magnet 2 move up and down more smoothly, a slide rail is provided in the chute 11, and the moving magnet 2 is arranged on the slide rail superior. Regarding the arrangement of the moving magnet 2 in the housing 1 , there is no essential difference from the prior art, so no further description will be given.

[0030] A first terminal piece 6 and a second terminal piece 7 are fixed side by side on the inner bottom of ...

Abstract

The invention relates to the field of proximity switches, in particular to a novel magnetic proximity switch. The novel magnetic proximity switch comprises a shell, wherein a movable magnet is arranged inside the shell and can move up and down, a first terminal piece and a second terminal piece are fixedly arranged on the bottom of the interior of the shell side by side with one on the left of the other, a fixed contact is arranged at the upper end of the second terminal piece, an elastic piece is arranged on the first terminal piece, a movable contact is arranged at the outer end of the elastic piece, and the movable contact corresponds to the fixed contact; an assistance rod is arranged in the middle of the interior of the shell and can swing in the shell, an assistance part is arranged at the inner end of the assistance rod, a limiting mechanism is arranged between the assistance rod and the shell, the movable magnet corresponds to the assistance part, an elastic tongue piece is arranged on the elastic piece, and the outer end of the elastic tongue piece abuts against the assistance part. According to the novel magnetic proximity switch, the structural arrangement is reasonable, acting force borne by the elastic tongue piece can be effectively controlled through the limiting mechanism, and the technical problem that in the prior art, metal fatigue and arc discharge are prone to occurrence is solved.

Description

technical field [0001] The invention relates to the field of proximity switches, in particular to a novel magnetic proximity switch. Background technique [0002] Magnetic proximity switches are widely used in various technical fields. It is a device that realizes switching through the interaction of moving magnets, static magnets and external magnets. Whether its structure is reasonable and scientific will directly determine the quality and service life of the new magnetic proximity switches. The reset mechanism of the existing magnetic proximity switch is generally an extension spring assembly. There are many irrationalities in this structure setting: 1. After the extension spring is used for a long time, the metal fatigue will cause the elastic force to decrease, the recovery speed will slow down, and the force will become smaller, which is easy 2. The installation of the extension spring assembly requires many matching parts, the structure is complex, the assembly is dif...
