Novel transformer base and transformer, and transformer terminal wiring method

Abstract

The invention discloses a novel transformer base and a transformer, and a transformer terminal wiring method. The novel transformer base is provided with a row of pins, including first pins for connecting a primary side and second pins for connecting a secondary side. The transformer comprises an iron core wound with a coil. The iron core is arranged on any one of the above transformer base. The method comprises the steps of arranging a row of pins on the transformer base, wherein the pins include the first pins for connecting the primary side and the second pins for connecting the secondary side; and allowing a wire inlet terminal and a wire outlet terminal for the coil at the primary side to respectively connect with different first pins. In the prior art, the wire is arranged across the top of the iron core of the transformer, while in the novel transformer base, two original rows of pins of the transformer base are changed into one row of pins, so that when the coil terminal needs to return to the same side, the coil terminal neither crosses the top of the transformer nor crosses the bottom end of the transformer, but directly connects to the pins from the lower end of the transformer.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to a novel transformer base, a transformer and a wiring method for transformer terminals. Background technique [0002] Chinese patent ZL02149696.X discloses "Transformer for Computer Switching Power Supply and Coil Winding Method", in which the winding method for the coil winding with an odd number of turns (2Q+1) is 180-degree rotationally symmetrical winding at the same position Make two (Q+0.5) coils, 0.5 of which is a non-integer circle, that is, a half circle, and the incoming and outgoing terminals of the two coil windings are then connected in parallel to form a single coil winding. [0003] Such as figure 1 As shown, the transformer for switching power supply in the prior art is a pin-type transformer. There are two rows of pins on the bottom of the iron core support, and the two rows of pins are inserted into the welding holes of the circuit board when the transforme...
