Detailed Description
Referring to the attached drawings, a miniature alternating current and direct current adjustable transformer comprises a bobbin and two wire holders 1, the bobbin comprises an inner barrel 2 and an outer barrel 3, the bottom end of the inner barrel 2 extends from the bottom of the outer barrel 3, the two wire holders 1 are respectively and fixedly connected to the outer side of the bottom end of the inner barrel 2 and the outer side of the top end of the outer barrel 3, a vertical through groove 4 is formed in the side wall of the outer barrel 3, a plurality of transverse clamping grooves 5 communicated with the vertical through groove 4 are sequentially formed in one side of the vertical through groove 4 from top to bottom, a pin 6 is fixedly connected to the outer wall of the inner barrel 2, the pin 6 is located in one of the transverse clamping grooves 5 and clamped at the front end of the transverse clamping groove, and can move along the vertical through groove 4 and the transverse clamping grooves 5.
In the utility model, the inner barrel 2 and the outer barrel 3 are cylinders.
The plurality of transverse clamping grooves 5 comprise straight grooves 5-1 and circular grooves 5-2 which are positioned at the front ends of the straight grooves 5-1 and communicated with the straight grooves.
The front end face of the pin 6 is flush with the outer surface of the outer cylinder 3 so as to avoid interference on the coil wound outside the outer cylinder 3.
The invention is further described below with reference to the accompanying drawings:
under normal conditions, the inner barrel 2 is completely contracted in the outer barrel 3, the bobbin is in a retraction state, the length of the bobbin reaches the minimum value, the pin 6 is located in the transverse clamping groove at the uppermost side and clamped at the front end of the transverse clamping groove, namely in the circular groove of the transverse clamping groove, and the number of turns of a coil which can be wound outside the bobbin is the minimum.
When needs increase the coil number of turns, rotatory inner tube 2 for in the horizontal draw-in groove at round pin post 6 breaks away from place and gets into vertical logical groove 4, round pin post 6 moves down along vertical logical groove 4, then counter-rotation inner tube 2, make round pin post 6 along a certain horizontal draw-in groove of below get into in it and block in its circular slot, the bobbin is in the state of extending, its length reaches corresponding regulating value, the outside coil number of turns that can coil of bobbin has obtained the increase.
When the length of the extended bobbin reaches the maximum value, the pin 6 is clamped in the transverse clamping groove at the lowest side, and the number of turns of the coil which can be wound outside the bobbin is the maximum.
The above embodiments are only described for the preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention, and the modifications and improvements made by the technical solutions of the present invention should fall into the protection scope of the present invention without departing from the design spirit of the present invention.
