Abstract
The utility model discloses an elastic component applied to an automatic change-over switch. A movable contact is arranged on the elastic component applied to the automatic change-over switch. The elastic component comprises an arc-shaped electrical connection plate region in which the movable contact is arranged, mounting plate regions which are fixedly arranged on connection regions on an insulation fixation plate and U-shaped elastic plate regions, wherein the U-shaped elastic plate regions connect the electrical connection region and the mounting regions. According to the utility model, the elastic component applied to the automatic change-over switch has the advantages of reasonable and simplified structure and stable and reliable working performance.
Description
Technical field
The utility model belongs to the electric machine structure design field, is specifically related to a kind of elastic component for automatic change-over.
Background technology
Monophase machine is in order to solve the starting current problem, need to be in the monophase machine rotating shaft sheathed automatic change-over, circuit is serially connected in and starts in the loop.Begin to start the loop during startup and begin to start by the centrifugal switch conducting, when reaching certain rotating speed, centrifugal switch disconnects automatically cutting off and starts the loop, starts and finishes, and motor becomes running status.
The centrifugal switch structure that conventional motors is used is comparatively complicated, and processing and manufacturing and maintenance thereof are all comparatively loaded down with trivial details, and because parts are more, easily break down, and its structure exists needs improvements badly.
The utility model content
The purpose of this utility model is to provide the elastic component that is used for automatic change-over that a kind of structure is comparatively simplified.
The technical scheme that realizes the utility model purpose is: a kind of elastic component for automatic change-over which is provided with moving contact; Described elastic component comprises electric connection board district be used to the arc shaped that moving contact is set, is used for being fixedly installed on the mounting panel district of each bonding pad on insulation fixing plate and is used for connecting the U-shaped elastic plate district that is electrically connected to district and installing zone.
In such scheme, described mounting panel district is positioned at the both sides that are electrically connected to the district.
The utility model structure is Rational Simplification comparatively, connects reset mode with shell fragment and has replaced traditional spring connection to reset, and its parts are less, and the source of trouble is also thereupon less, and service behaviour is comparatively reliable and stable.
