Embodiment
About aforementioned and other technology contents, characteristics and effect of the present utility model, in the detailed description in following cooperation with reference to the preferred embodiment of accompanying drawing, can clearly present.Before the utility model is described in detail, be noted that in the following description content, similarly element is to mean with identical numbering.
Figure 3 shows that height of the present utility model is pressed with the constitutional diagram that carries the adjustable transformer device.As shown in Figure 3, just being pressed with a year adjustable transformer device 300 comprises: a servo motor 301, a driver 302, a tubulose winding base 303, a coil windings 305, a brush 304 and track 306.Wherein servo motor 301 sees through driver 302 and drives tubulose winding base 303 to rotate clockwise or the counterclockwise rotation.304 of brushes can slide on track 306, and the coil number contacted with coil windings 305 with adjustment is with output specific voltage value.In the utility model, be provided with screw-like channels 3031 on tubulose winding base 303, coil windings 305 is arranged in this screw-like channels 3031, therefore when servo motor 301 sees through driver 302 drive tubulose winding base 303 rotation, this screw-like channels 3031 can be guided brush 304 and slide on track 306, the coil number that causes brush 304 to contact with coil windings 305 changes, and causes the change of output voltage values.
Figure 4 shows that the summary enlarged drawing of the utility model tubulose winding base.Wherein tubulose winding base 303 is the structures that always are equipped with a perforation 308.This tubulose winding base 303 is by an insulating material, for example: fiber, bakelite or plastic cement, institute forms, be that tubulose winding base 303 is a fiber tubulose winding base, bakelite tubulose winding base or plastic cement tubulose winding base, dug screw-like channels 3031 on it, two 3031 of adjacent screw-like channels separate with insulating wall 3032, and 305 of coil windings follow insulating wall 3032 orders to be set around in this screw-like channels 3031.In one embodiment, the width A of groove 3031 bottom lands need be greater than the width B of insulating wall 3032.See through the setting of insulating wall 3032, two adjacent windings windings 305 can effectively reach the effect of insulation, therefore the skin of coil windings 305 can not need the coated insulation material, that is to say, coil windings 305 of the present utility model can be directly with electric conducting material, for example: bare copper wire is set around in this screw-like channels 3031 and is formed, therefore do not need again, via processing procedures such as pressing, grinding and plating, to expose inner wire.In addition, a columnar silicon steel disc 307 is arranged in this perforation 308.302 of drivers are arranged in this columnar silicon steel disc 307, and servo motor 301 can see through driver 302 and drive tubulose winding base 303 and rotated with the direction of clockwise or the direction of inverse clock whereby.
On the other hand, Figure 5 shows that the schematic diagram that brush 304 contacts with coil windings 305.Because coil windings 305 of the present utility model is to be arranged in screw-like channels 3031, and with insulating wall 3032, adjacent coil windings 305 is separated.Therefore, brush 304 can be restricted in screw-like channels 3031.And when servo motor 301 sees through driver 302 and drives tubulose winding base 303 and rotate, follow the rotation of screw-like channels 3031 and move, the coil number variation that causes brush 304 to contact with coil windings 305 and change output voltage values.Due to, brush 304 is restricted in screw-like channels 3031, therefore brush 304 only contacts a line in coil windings 305, do not have the problem that causes many coils of cross-over connection because of brush 304 wearing and tearing, and because brush 304 is to follow the rotation of screw-like channels 3031 and move, therefore can guarantee and the contacting of coil windings 305, and not have the problem of instant cut-off.
Its center brush 304 can be directly with an electric conducting material, and for example the System of copper institute becomes.And the end of brush 304 more can arrange a spring 309, so as to increasing the contact force of 305 of brush 304 and coil windings.When servo motor 301 sees through driver 302 drive tubulose winding base 303 rotation, screw-like channels 3031 can be guided brush 304 and slide on track 306, and the coil number that causes brush 304 to contact with coil windings 305 changes, and causes the change of output voltage values.For example, in one embodiment, when servo motor 301 rotates with the direction of clockwise through driver 302 drive tubulose winding base 303, screw-like channels 3031 guiding brushes 304 slide towards arrow 310 directions on track 306, the coil number that now causes brush 304 to contact with coil windings 305 increases, thereby promotes output voltage values.Otherwise, when servo motor 301 rotates with the direction of inverse clock through driver 302 drive tubulose winding base 303, screw-like channels 3031 guiding brushes 304 slide towards arrow 311 directions on track 306, the coil number that now will cause brush 304 to contact with coil windings 305 reduces, thereby reduces output voltage values.So it should be noted that, in other embodiment, also can make the rotation clockwise of tubulose winding base 303 be defined as the reduction output voltage values by revising the hand of spiral of screw-like channels 3031, and the counterclockwise rotation be defined as the increase output voltage values.
In sum, tubulose winding base of the present utility model has dug screw-like channels on it, between two adjacent screw-like channels, with insulating wall, separates, and coil windings follows insulating wall sequentially to be set around in this screw-like channels.See through the setting of insulating wall, two adjacent windings windings can effectively reach the effect of insulation, so the skin of coil windings can not need the coated insulation material, therefore do not need, via processing procedures such as pressing, grinding and plating, to expose inner wire again.Moreover, brush can be restricted in screw-like channels, and follow the rotation of screw-like channels and move, therefore brush only contacts a line in coil windings, do not have the problem that causes many coils of cross-over connection because of wear of brush, and because brush is to follow the rotation of screw-like channels and move, so can guarantee and the contacting of coil windings, and not have the problem of instant cut-off.
Although the utility model discloses as above with execution mode; so it is not in order to limit the utility model; anyly be familiar with this skill person; within not breaking away from spirit and scope of the present utility model; therefore when being used for a variety of modifications and variations, protection range of the present utility model is as the criterion when looking the scope that appending claims defines.
