Abstract
A plug and receptacle electrical connector has incorporated within one of its parts an insulative enclosure maintaining the pin or sockets contacts, as the case may be, in an electrically insulated relation, which enclosure also has cavities formed about each of the pin contacts for receiving inductors and/or one or more specially formed capacitors therein. Each inductor is an elongated hollow cylinder formed of a magnetic material (e.g., sintered ferrite), one such inductor being received within a member cavity and the pin (or socket) contacts on being assembled in the connector part extending through the respective inductor openings. A capacitor consists of an insulative cylinder with an axial opening therethrough and has select portions coated with first and second electrically conductive film electrodes. One film electrode provides interconnection between adjacent capacitors when they are stacked within the receiving cavities and with springlike contacts which interconnect one terminal of the capacitor/s to an electrically conductive ground shell. The other terminal of each capacitor is connected to a pin or socket contact, as the case may be.
