Abstract
The utility model relates to an anti-explosion magnetic controlled switch which is composed of a switch body and a pressing knob body, wherein a movable reed is arranged in the switch body, an armature is arranged on the end part of the movable reed and a permanent magnet is arranged in the pressing knob body. The utility model has the advantages of sealed structure, explosion isolation, explosion prevention, etc.
Description
The utility model relates to a kind of flame-proof switch, in particular for the explosion preventing gate switch of refrigerator.
At present, existing door of refrigerator switch adopts overall structure on the market, and is gapped between the button of this switch and the shell, can not form the structure of sealing.
The purpose of this utility model provides a kind of hermetically-sealed construction, explosion-proof magnetic switch that can be explosion-proof.
For achieving the above object, the technical scheme that the utility model requires to take is a kind of explosion-proof magnetic switch, it is made up of switch body and press button body, switch body comprises shell, connect changing device, clip, movable reed, the opening part of shell is by connecing the changing device sealing, connect and be fixed with clip and movable reed on the changing device, clip and movable reed are in shell and connect in the formed seal cavity of changing device, movable leaf end also is provided with armature, the press button body comprises permanent magnet, press button, the permanent magnetism base, stage clip, press button and permanent magnetism base are interlockingly connected, and establish permanent magnet in the press button, be provided with stage clip in the permanent magnetism base, stage clip is pressed on permanent magnet in the permanent magnetism base.
Compare with existing switch in the market, the utility model is owing to adopt the reed contact in the switch to be controlled by magnet, and reed can be contained in the shell of sealing, forms hermetically-sealed construction and prevents that switching circuit from connecing that spark leaks when changing, and reaches the purpose of flame-proof explosion-proof.
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail.
Accompanying drawing is the explosion-proof magnetic switch structural representation of the utility model.
Explosion-proof magnetic switch shown in the drawings partly is made up of switch body and press button body two, switch body by shell 3, connect changing device 1, clip 5,8, movable reed 9, armature 10 etc. and form.The press button body is made up of permanent magnet 2, press button 6, permanent magnetism base 4, stage clip 7 etc., and clip 5,8, movable reed 9 and end armature 10 thereof all are positioned at shell 3 inside, and permanent magnet 2 is positioned at press button body inside.When switch body contacted with the press button body, permanent magnet 2 was inhaled mutually with armature 10, movable reed 9 and group clip 8 disconnections down during attraction, and connect with last group of clip 5.When the press button body left switch body, permanent magnet 2 reduced with the suction of armature 10, movable reed 9 recovers contact with group clip 8 down under himself forceful action, with on organize the clip disconnection, reach switching circuit and connect the purpose of changing.
