The transformer has a bobbin, a coil assembly and a magnetic core assembly. The bobbin is mounted in the magnetic core assembly and has multiple connecting pins being formed on at least one side of a bottom surface of the bobbin. Each connecting pin has a top surface as a soldering surface that corresponds to a solder pad on a back of a circuit board. At least one fastener is further formed on the bottom surface of the circuit board. Therefore, when the transformer is mounted through the circuit board, the connecting pins are soldered on the back of the circuit board to reduce the total thickness of the combination of the transformer and the circuit board.

Transformer and transformer assembly

A rotary adapter comprises a main body, a fixing piece, and a plug. The main body further comprises: a circular recess containing a central platform; a plurality of first fastening portions spaced along the inner edge of the circular recess; and a channel formed with a positioning block and two symmetrical guide tracks disposed on respective banks thereof. The fixing piece is provided with a rail on each of two sides thereof corresponding to the guide tracks, and with a retaining portion arranged on one side of the fixing piece. The plug contains a circular base corresponding to the circular recess for the plug to rotate in the circular recess of the main body, in which a positioning receptacle at a position corresponding to the positioning cylinder is centrally formed in the circular base; a plurality of second fastening portions is arranged surrounding the circumferential edge of the circular base corresponding to the first fastening portions for buckling the plug with the main body; and a gap is defined in the circumference of the circular base of the plug and correspondent to the retaining portion of the fixing piece such that the plug can be fixed in the circular recess.
