Definitions

  • Each of US-A-5.161,999, and US-A-5, 167.531 discloses a shielded connector assembly constructed with two electrical headers for connection to plug type electrical connectors. Two shells encircle respective headers to provide shielding. The headers and the two shells are mounted to a conducting bracket. A third shell mounts on the bracket and covers a rear of each of the headers.
  • This connector assembly is bulky, because of a relatively large number of separate parts, comprising a mounting bracket, two headers, two shells encircling respective headers, and a third shell. It would be desirable to provide an electrical connector comprising multiple plug receiving cavities, wherein each of the plug receiving cavities is encircled by shielding, and wherein the connector is comprised of a reduced number of separate parts to achieve a compact size.
  • US-A-5,387,114 discloses a shielded electrical connector comprising a conducting outer shell encircling an insulating housing, and a conducting second shell engaging the outer shell. Electrical contacts are received inside respective cavities in the housing.
  • the second shell extends along slots in the housing; the slots are beside the cavities without being inside the cavities, with portions of the housing separating the slots from the cavities. These housing portions prevent the second shell from engaging portions of a mating plug type connector that are to be inserted inside the cavities for mating with the contacts therewithin. It would be desirable to provide an electrical connector with an improved compact size that is achieved by a shield extending inside multiple plug receiving cavities to engage respective plugs that are to mate with electrical contacts inside the cavities.
  • the invention pertains to a shielded electrical connector, a compact size of which is achieved by extending a conducting shell inside multiple plug receiving cavities to engage respective plugs that are to mate with electrical contacts inside the cavities.
  • the invention is constructed with a reduced number of parts, as compared with prior electrical connectors, thereby simplifying assembly and reducing fabrication costs.
  • a shielded electrical connector comprises an insulating housing, a conducting outer shell encircling the housing, and a conducting second shell engaging the outer shell to provide electrical shielding, electrical contacts extending inside multiple plug receiving cavities in the housing, the second shell extending inside each of the plug receiving cavities to engage electrical plug type connectors to be received in the plug receiving cavities.
