Abstract
The utility model relates to a novel rotary switch, belonging to the field of a rotary switch, wherein a torsional spring is connected with a handle in a manner of cup joint, the upper end of the handle passes through a guiding positioning through hole, an electric conductive bar is arranged to pass through the lower end of the handle, the bottom portion of the handle is provided with a lower cover, between the handle and the lower cover there is provided a spring, the spring is connected with an inching terminal in the manner of cup joint, the inching terminal is inserted into the center of the lower cover, one end of a common terminal and one end of each tap position terminal are respectively inserted into the corresponding holes inside the lower cover. The novel rotary switch is simple in structure, avoids the instability caused by an in-place connection piece, is good in contact performance, has an elastic device for reducing wear, and is high in safety and convenient in use.
Description
Technical field:
The utility model relates to the rotary switch field, is specifically related to a kind of Novel rotary switch that is applicable to the energy-conservation equipment such as motor control, Current Control.
Background technology:
Rotary switch can be used for replacing the rotary pulsed generator of traditional electrical resistive potentiometer analog functuion, and it is a kind of switch of controlling the main contacts break-make with rotary handle.
Rotary switch cost in the market is high, complex structure, and is easy to wear, has certain potential safety hazard, and its useful life is shorter.
The utility model content:
The purpose of this utility model provides a kind of Novel rotary switch, and it is simple in structure, has avoided because of to the unsteadiness brought of some brace, and its contact performance is good, and elastic device can reduce wear, and is safe, the convenient use.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: it comprises loam cake 1, guide-localization through hole 2, torsion spring 3, handle 4, contact rod 5, spring 6, public terminal 7, crawl terminal 8, gear terminal 9, lower cover 10 and screw 11; Torsion spring 3 is socketed on the handle 4, and handle 4 upper ends are located in the guide-localization through hole 2, contact rod 5 is located in the lower end of handle 4, the bottom of handle 4 is provided with lower cover 10, and be provided with spring 6 between handle 4 and the lower cover 1, spring 6 is socketed on the crawl terminal 8, and crawl terminal 8 is inserted into the center of lower cover 10, one end of public terminal 7 and gear terminal 9 is inserted in the lower cover 10 interior corresponding holes, and loam cake 1 and lower cover 10 spin fixing by screw 11.
Described public terminal 7 and crawl terminal 8 are connected in series a circuit as rotary switch with the resistance of outside respectively, and gear terminal 9 is connected in series another circuit that forms rotary switch with non-essential resistance.
Described spring 6 is connected in the centre bore of handle 4 bottoms, reduces wear, and improves contact performance, increases the service life.
The terminal outer meeting resistance that the utility model is set the gear terminal 9 of arranged clockwise reduces successively, electric current by terminal just increases successively, the outer meeting resistance resistance of public terminal 7 is identical with the outer meeting resistance resistance of crawl terminal 8, when clockwise rotating handle 4, contact rod 5 contacts successively with gear terminal 9, because the electric current by gear terminal 9 is different, realized the effect of by-pass cock speed, when rotating counterclockwise handle 4, contact rod 5 is connected with public terminal 7 contacts, when handle 4 can't rotate, and release handle 4, contact rod 5 clockwise rotates, and in the position that under the effect of spring 6, rests on crawl terminal 8.
The utility model is simple in structure, has avoided because of to the unsteadiness brought of some brace, and its contact performance is good, and elastic device can reduce wear, and is safe, the convenient use.

Embodiment:
Referring to figs. 1 through Fig. 4, this implementation by the following technical solutions: it comprises loam cake 1, guide-localization through hole 2, torsion spring 3, handle 4, contact rod 5, spring 6, public terminal 7, crawl terminal 8, gear terminal 9, lower cover 10 and screw 11; Torsion spring 3 is socketed on the handle 4, and handle 4 upper ends are located in the guide-localization through hole 2, contact rod 5 is located in the lower end of handle 4, the bottom of handle 4 is provided with lower cover 10, and be provided with spring 6 between handle 4 and the lower cover 1, spring 6 is socketed on the crawl terminal 8, and crawl terminal 8 is inserted into the center of lower cover 10, one end of public terminal 7 and gear terminal 9 is inserted in the lower cover 10 interior corresponding holes, and loam cake 1 and lower cover 10 spin fixing by screw 11.
Described public terminal 7 and crawl terminal 8 are connected in series a circuit as rotary switch with the resistance of outside respectively, and gear terminal 9 is connected in series another circuit that forms rotary switch with non-essential resistance.
Described spring 6 is connected in the centre bore of handle 4 bottoms, reduces wear, and improves contact performance, increases the service life.
The terminal outer meeting resistance that this implementation is set the gear terminal 9 of arranged clockwise reduces successively, electric current by terminal just increases successively, the outer meeting resistance resistance of public terminal 7 is identical with the outer meeting resistance resistance of crawl terminal 8, when clockwise rotating handle 4, contact rod 5 contacts successively with gear terminal 9, because the electric current by gear terminal 9 is different, realized the effect of by-pass cock speed, when rotating counterclockwise handle 4, contact rod 5 is connected with public terminal 7 contacts, when handle 4 can't rotate, and release handle 4, contact rod 5 clockwise rotates, and in the position that under the effect of spring 6, rests on crawl terminal 8.
This implementation is simple in structure, has avoided because of to the unsteadiness brought of some brace, and its contact performance is good, and elastic device can reduce wear, and is safe, the convenient use.
