Patent Application
20130171874
The present invention is generally related to connectors, and more particular to a connector with a built-in filtering module.
Various connectors are widely used in electronic appliances and industrial apparatus. The connectors provide electrical connection upon which information and/or electricity is delivered. There are connectors with built-in filtering module such as the RJ connectors. This kind of connectors usually contains a port member, a base board, and a filtering module. The filtering module usually consists of a number of coils, each containing a ferrite ring core with windings by conductive wires.
As shown in
Such filtering modules have a number of disadvantages. For example, the windings for the ferrite ring core 31 have to be achieved manually which leads to long production time and instable quality.
A major objective of the present invention is to adopt amorphous ring core so as to obviate manual winding and to achieve enhanced quality and short production time.
Another objective of the present invention is to achieve reduced magnetic impedance for high-frequency applications by winding a conductive wire on the amorphous core ring.
To achieve the above objectives, the connector contains a port member, a base board electrically connected to the port member, and a filtering module electrically connected to the base board. The filtering module contains a number of vertically stacked circuit boards. There are a number of layout areas on each circuit board. Between a pair of adjacent circuit boards, an amorphous ring core is configured correspondingly to each layout area. Through the conduction between the amorphous ring core and the circuits in the layout areas, the amorphous ring core is capable of filtering. The amorphous ring core does not require manual winding, and have advantages such as stable quality and reduced production time.
The foregoing objectives and summary provide only a brief introduction to the present invention. To fully appreciate these and other objects of the present invention as well as the invention itself, all of which will become apparent to those skilled in the art, the following detailed description of the invention and the claims should be read in conjunction with the accompanying drawings. Throughout the specification and drawings identical reference numerals refer to identical or similar parts.
Many other advantages and features of the present invention will become manifest to those versed in the art upon making reference to the detailed description and the accompanying sheets of drawings in which a preferred structural embodiment incorporating the principles of the present invention is shown by way of illustrative example.
The following descriptions are exemplary embodiments only, and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention.
