Abstract

The invention provides a double-wire winding transformer. The transformer comprises a transformer main body and a coil wound on the transformer main body, wherein the transformer main body consists ofa first body, a second body, a third body and a fourth body; the surface of the second body is coated with an organic material or an inorganic material, the surface of the first body and the bottom of the second body are subjected to mirror surface treatment, and the second body is bonded and fixed at the top of the first body; the third body and the fourth body are bonded and fixed to two ends of the top of the second body, and electrodes are compounded on the surfaces of the third body and the fourth body through vacuum electroplating or traditional electroplating modes. After the scheme isadopted, the residual rate of a substrate is high, tin soldering high-temperature resistance is achieved, tin attachment property is good, and pseudo soldering is avoided; remote signal transmissionis realized.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to a double-wire wound transformer and a preparation method thereof. Background technique [0002] The transformer consists of an iron core (or magnetic core) and a coil. The coil has two or more windings. The winding connected to the power supply is called the primary coil, and the remaining windings are called the secondary coil. It can transform AC voltage, current and impedance. The existing coils are all single-wire windings, and the transmitted signals are close to each other, so the use effect is not good. At the same time, the existing electrodes are directly glued to the surface of the iron core, and its use effect is not good. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of the prior art, and provide a double-wire winding transformer with high temperature resistance to soldering, good tin attachment, no fals...
