Description
Technical field
This utility model relates to a kind of many grades of speed-regulating switch.
Background technology
Speed-regulating switch is a kind of conventional electrical equipment, its range of application is quite varied, existing speed-regulating switch generally comprises the first conductive contact blade and some second conductive contact blades, realize the first conductive contact blade and a second conductive contact blade docking by rotating the first conductive contact blade or dock with multiple second conductive contact blades simultaneously, first conductive contact blade of this class formation and the second conductive contact blade are the ways of contact of left and right friction, contact process is a progressive action, need the of short duration time just can complete stable contact, and contact process can produce electric arc, the service life of impact switch, and noise is bigger during the switch of this structure.
Summary of the invention
In order to solve the problems referred to above, this utility model provides a kind of many grades of speed-regulating switch.
This utility model solves its technical problem and be the technical scheme is that
A kind of many grades of speed-regulating switch, including resilient second conductive contact blade of upper shell, lower house, the first conductive contact blade, rotating disk and some tools, described rotating disk is installed in rotation in upper shell and lower house, described rotating disk is arranged with some sections of diameters and the most different circular arc projection of length, ringwise, the first conductive contact blade is arranged in lower house described first conductive contact blade；Described second conductive contact blade one end is arranged on lower house, the other end extends to above the first conductive contact blade, being provided with on second conductive contact blade and the projection of circular arc protrusions match, the bump position on each second conductive contact blade all differs, and corresponding from different circular arc projections respectively.
On described second conductive contact blade, corresponding second conductive contact blade position is provided with contact.
Being provided with some plug wire holes on described lower house, described second conductive contact blade extends in plug wire hole, is additionally provided with a tool resilient compression sheet in described plug wire hole, and compressing angle between sheet and the second conductive contact blade in plug wire hole is acute angle.
The end at described circular arc projection two ends is seamlessly transitted with rotating disk by curved surface.
The beneficial effects of the utility model are: this utility model of employing said structure is by arranging rotating disk, and controls rotating disk rotation, and then controls the second conductive contact blade and the quantity of the first conductive contact blade contact；The first conductive contact blade in this utility model and the second conductive contact blade are the upper and lower ways of contact simultaneously, the new way of contact, connecting and disconnecting action energy moment completes, and is avoided that the generation of electric arc between the first conductive contact blade and the second conductive contact blade in prior art, is conducive to improving the life-span；This structure operationally noise is relatively low, and the contact between the second conductive contact blade and the first conductive contact blade is good all the time, and working stability, service life is longer.
