US 8,011,963 B2 · Filtered power connector

Abstract

An improved power connector provides improved signal integrity in an interconnection system. The connector includes a filter element between a supply contact and a return contact. The filter element may be primarily capacitive, but may also include a resistance and a ferrite member. For connectors that include multiple sets of supply and return contacts, a single filter element may be included, or multiple filter elements may be included between multiple pairs of power and return contacts. The filter element may be formed within a connector housing or otherwise incorporated when the connector is manufactured. Alternatively, the filter element may be inserted into a receptacle such that filtering may be selectively incorporated as the connectors are used. When connected to a conducting loop for carrying power supply, the filter element provides substantially zero attenuation at frequencies below about 50 MHz and in excess of 10 dB of attenuation over a range that extends above 500 MHz.
