Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be further described with reference to the following embodiments. Wherein the showings are for the purpose of illustration only and are shown by way of illustration only and not in actual form, and are not to be construed as limiting the present patent; it will be understood by those skilled in the art that certain well-known structures in the drawings and descriptions thereof may be omitted.
The utility model discloses an electric break-make subassembly for low current pressure switch specifically includes support, movable contact inserted sheet 1 and stationary contact inserted sheet 2, and mutual riveting is formed with movable contact, stationary contact between the one end of movable contact inserted sheet 1 and stationary contact inserted sheet 2, and the support is used for breaking off and the connection of switch-on movable and stationary contacts to realize the disconnection and the switch-on of electrical component. Specifically, the bracket comprises a bracket body 3, two ends of the bracket body are perpendicular to the bracket body and extend outwards horizontally to form movable arms 4, the movable arms 4 are inclined downwards horizontally relative to the bracket body, the middle part of the left side of each movable arm is positioned above a contact ejection ring during assembly, a door-shaped pressing plate 5 is formed upwards at one end of each movable arm close to the bracket body, a movable contact insert is horizontally suspended and penetrates through the door-shaped pressing plate and is not contacted with the door-shaped pressing plate, a abdication part 6 is formed at one end of each movable contact insert, which is far away from the door-shaped pressing plate, a connecting bolt hole is formed in the center of the abdication part 6, one end of each movable contact insert, which is close to the door-shaped pressing plate, is riveted with a fixed contact insert to form a movable contact 7, a fixed contact 8 is formed at the riveted part of the fixed contact insert, the fixed contact is positioned above the movable contact, and the fixed, a connecting bolt hole is formed in the center of the support portion 9.
This electrical on-off subassembly sets up on low current pressure switch's base, and the left side middle part of its digging arm is located contact and backs down the circle top, and the left end of this digging arm compresses tightly through pressure switch's main part cooperation spring, makes it rotatory as the center pin with the digging arm left end in certain extent. After the contact is pushed to move upwards on the opening ring, the middle part of the left side of the movable arm can be pushed to move upwards, the support body moves downwards, the movable contact inserting piece is pressed downwards by the door-shaped pressing plate, the movable contact of the movable contact inserting piece is far away from the static contact of the static contact inserting piece, and therefore electrical connection is disconnected. After the contact ejection ring moves downwards to return to the original position, the support body drives the door-shaped pressing plate to move upwards, the movable contact insertion piece is not pressed, the movable contact insertion piece returns to the original position under the elastic action of the movable contact insertion piece, and the movable contact and the static contact are in contact and are electrically communicated.
