An integrated transformer and an electronic device are provided. An integrated transformer includes at least one substrate defining a plurality of annular accommodating grooves. Each annular accommodating groove divides a corresponding substrate into a central part surrounded by the each annular accommodating groove and a peripheral part arranged around the each annular accommodating groove. The central parts and the peripheral parts, magnetic cores received in the annular accommodating grooves and conductive connectors assembled on the at least one substrate, and transmission wire layers on both sides of the at least one substrate cooperatively constitute a plurality of transformers and filters arranged according to preset arrangement manners. At least one of the transformers and at least one of the filters are electrically connected to form a group of electromagnetic assemblies, and any two groups of electromagnetic assemblies are not electrically connected with each other on the at least one substrate.

Integrated transformer and electronic device

An electromagnetic device includes a substrate, magnetic cores, transmission line layers, and conductive members. The substrate is provided with annular receiving grooves for accommodating the magnetic cores; the substrate is divided into a central portion and a peripheral portion; inner and outer via holes are respectively formed on the central portion and the peripheral portion, respectively; the transmission line layers each including wire patterns are respectively provided on opposite sides of the substrate; and the conductive members are sequentially connected to the wire patterns on both sides of the substrate to form a transformer and/or a filter; the electromagnetic device has a first side provided with a slot and a second side parallel to the transmission line layers; and first conductive pins electrically connected to the at least one transmission line layers are provided on at least one of the side wall surrounding the slot and a second side.

Electronic device, connector, and electromagnetic device thereof

A transformer, a method for manufacturing the same and an electromagnetic device are disclosed. The transformer includes a base plate, a magnetic core, transmission wire layers and conductive parts. The base plate includes a central part defining multiple inner via holes each running through the base plate and a peripheral part defining multiple outer via holes each running through the base plate. An annular accommodating groove is defined between the central pan and the peripheral part. The magnetic core is received in the accommodating groove. The transmission wire layers may be disposed respectively on two opposite sides of the base plate. Each of the transmission wire layers includes multiple wire patterns. Multiple conductive parts are respectively disposed in the inner via holes and the outer via holes.

Transformer, electromagnetic device and manufacturing method of the transformer

An integrated transformer and an electronic device are disclosed. The integrated transformer includes at least one first base plate and at least one second base plate. Each of the first and second base plate defines multiple annular accommodating grooves. The annular accommodating grooves divide each of the first and second base plate into multiple central parts and a peripheral part Each central part defines multiple inner via holes there through. The peripheral part defines multiple outer via holes there through. The integrated transformer further includes multiple magnetic cores disposed in the respective annular accommodating groove and transmission wires disposed on both sides of the first and second base plates. Transformers and the filters are arranged on two base plates respectively, and the thickness of the transmission wire layers of the filters is less than that of the transformers. Thus, the structure of the electromagnetic device may be more compact.
