Abstract

The invention discloses a transformer which solves the problems that the electroplating period of the surface of a magnetic core electrode position is long and side electroplating cannot be carried out, reduces the overall structure size and widens the product application scene. The transformer comprises a magnetic core and a coil winding arranged on the magnetic core, the magnetic core comprises a wrapping post and two side plates on the two sides, the wrapping post is arranged between the two side plates on the two sides, a coil winding is wound on the wrapping post, and the top ends of the two side plates are respectively provided with a plurality of positioning seats which are arranged at intervals; the magnetic core comprises a magnetic conductive main body; a spacer is arranged on the positioning seat; a bonding pad is arranged on the spacer, and an electrode lead is arranged on the bonding pad; and a plurality of electrode leads of the coil winding are respectively arranged on the bonding pads of the corresponding isolating pieces. The transformer can be applied to transformers, surface-mounted transformers, common-mode inductors, power transformers and the like, and is applied to Netcom markets, RJ45 connector isolation, communication transmission and the like.

Description

technical field [0001] The invention belongs to the technical field of transformers, in particular to a transformer which solves the short-circuit prevention problem of conductive magnetic materials. Background technique [0002] The material used in existing transformers is non-conductive nickel-zinc material, the inductance value is relatively low, the number of winding coils is too large, the impedance matching is not easy to adjust, and the main structure of conductive manganese-zinc material cannot be used. The main frame is not conductive and cannot plate solder pads. [0003] The existing transformer has an integrated body structure, and the pads are connected to the main body by means of copper sheets; or the electroplated pads are connected to the main frame through a process. Contents of the invention [0004] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a transformer that solves the problems of long electropl...
