<p>The present invention is directed to electrical connectors of a type providing protection from electromagnetic interference (EMI), While multiple contact filter connectors of the prior art have proven successful when used to conduct relatively low RF currents of approximately one-quarter ampere they have not been suitable for conducting high RF currents of, for example, three or more amperes. Because the ground plates are thin, the heat generated by high current conduction cannot be adequately dissipated. As a result, the connectors overheat and, ultimately, fail. The present invention overcomes these deficiencies of the prior art by providing an improved multiple contact filter connector capable of accommodating high RF currents and a method of manufacturing the same. The connector includes an outer metalic shell, a dielectric body within the shell and at least one network filter contact assembly. The inner body has at least one through channel and a transverse cavity which communicates with the shell and the channel. The network filter contact assembly has a ground electrode and a pin electrode and Is disposed within the portion of the channel bridging the cavity. Conductive curable filler material is charged into the cavity around and in contact with the ground electrode to efficiently and inexpensively establish a ground plate for the connector. A retention means disposed within the channel and a locking means carried by the contact cooperate to provide axial strain relief, thereby protecting the bond between the conductive filler material and the ground electrode.</p> |
