Abstract
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.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
194 words
A filter package adapted for use with a plug and receptacle connector in which a pin contact is releasably mated with a socket contact, comprising: enclosure means having an opening extending therethrough for receiving a connector contact and including first and second enlarged spaced apart cavities located along said opening and in open communication with said opening; a body of magnetic material having an opening of a size enabling fitting receipt of the connector contact therethrough, said magnetic body being received in the means first cavity with the body opening aligned with the enclosure opening; a substantially cylindrical capacitor having an axial opening of a size enabling receipt of the connector contact therethrough, said capacitor having first and second terminal electrodes on a peripheral surface and one end surface of said capacitor, respectively; said second electrode is deposited within a recess in the capacitor end, a conductive member being received in said recess, said member having parts extending beyond the capacitor end, and a conductive disc clampingly received onto the conductive member parts and contacting the connector contact; and spring contact means carried by said enclosure means contacting one of said capacitor terminal electrodes.
