Abstract: An EMI magnetic bead inductor comprises a magnetic core and at least one metal pin group. The metal pin group includes at least one first metal pin. The first metal pin has two first inserting portions and one first connecting portion. First ends of the two first inserting portions are connected by the first connecting portion. The magnetic core is provided with a plurality of insertion holes. Second ends of the two first inserting portions are inserted into two said insertion holes from first ends of the two said insertion holes and protrude from second ends of the two said insertion holes.

Abstract: A multilayer inductor comprises a plurality of magnetic layers and metal electrode tracks formed on the magnetic layers. A ceramic-inorganic material composite is placed in the magnetic core area in the pattern of coils formed by the metal electrode tracks. The ceramic-inorganic material composite comprises two or more first layers and second layers. The first layers comprise a ceramic material having a positive slope of the dielectric constant versus temperature curve. The second layers comprise an inorganic material having a negative slope of the dielectric constant versus temperature curve. The first layers and the second layers are stacked on each other in an alternating manner. The metal electrode tracks are arranged in such a way that the void space between two adjacent metal electrode tracks where no effective magnetic lines of force exist is minimized. The multilayer inductor enables stable device characteristics and enhances the inductive performance.

Abstract: The present invention discloses a press-fit connector and a wireless charging coil module, the press-fit connector is connected to a package module, the package module can be inserted and matched with an external module, wherein the press-fit connector comprises: a connector housing having at least one press-fit terminal disposed thereon, the press-fit terminal being formed with a plug end protruding from the connector housing; and a flexible adjustment member connected between the connector housing and the package module, the flexible adjusting member being capable of adjusting an interface position of each plug end and each inserting slot of the external module in a state that the package module is interfaced with the external module. With the press-fit connector and the wireless charging coil module of the present invention, it is possible to save the welding process cost of at client side and facilitate plug and play by the client.
