Definitions

  • This invention relates to a connector device which contains an integral referenceplane for applying a reference potential to an electrical filter utilized as part of the connector.
  • connectors In order to prevent noise from passing from one electrical element to another through the connector joining them, connectors have recently been designed which include, as part of each connector pin, a filter element which is adapted to pass only signals at the desired frequency.
  • the filters generally utilized for this purpose have an electrically conducting outer.
  • the casing of the connector is established as a ground reference and a bulkhead is inserted into this hollow casing and secured in place by spring clips.
  • the spring clips are of electrically conducting material and, since they contact both the casing and the bulkhead, they serve to apply a ground potential to the bulkhead.
  • the bulkhead has a plurality of openings through which the pins containing the filters are passed. Spring clips mounted in each of these openings serve to apply the desired ground potential to the shell of each of the filters.
  • Existing connectors have also applied ground potential to the bulkhead by substituting a solder joint for the spring clips or by pressure fitting the bulkhead into the connectors.
  • the connector described above thus requires at least two electrical connections in order to obtain the desired potential at the shell of the filter. Each of these connections increases the impedance between ground and the filter shell and also serves as a possible source of discontinuity in the electrical path.
  • the assembly of such a connector is also relatively complex involving delicate operations both in the insertion of the springs in the casing and in the positioning of the bulkhead.
  • the space between the casing and the bulkhead also provides another opening through which electromagnetic interference (EMI) leakage may occur. It is thus apparent that, if the number of contacts required to apply ground potential to the shell of the filter could be reduced, an improved filter connector would be obtained.
  • EMI electromagnetic interference
  • a still more specific object of this invention is to provide a means for reducing the number of electrical contacts required to obtain a reference potential in a connector of the type described above.
  • this invention provides a connector device having a hollow elongated casing of an electrically conducting material.
  • a bulkhead formed as an integral part of the casing is positioned to block the hollow opening in the casing and has a plurality of holes formed in it.
  • a spring clip of electrically conducting material is mounted in each of the holes in a manner such that it makes electrical contact with the bulkhead.
  • Pin means each of which includes as a part thereof a filter having an outer surface of conductive material, are adapted to pass through each of the holes.
  • Each of the filters is dimensioned so as to cause its outer surface to be in electrical contact with the corresponding clip when the pin means is properly positioned in a hole.
  • the single FIGURE is a partially cutaway diagram of a preferred embodiment of the invention.
  • the connector in the preferred embodiment of the invention is made up of two sections, a casing 10 and a locking insert 12.
  • the casing 10 is forged of an electrically conducting metallic material such as an aluminum. It includes a flange 14 for the securing the connector to some external member, an external screw thread 16 for securing a plug or female connector to the connector, an internal screw thread 18 for securing the locking insert 12 to the casing 10, and a bulkhead 20 which forms a barrier across the connector interior.
  • Bulkhead 20 is forged as an integral part of casing 10. A plurality of holes 22 are drilled in bulkhead 20 and spring clips 24 are pressed into each of these holes.
  • insert 12 includes an outer shell 40 having an external thread 42 which is adapted to coact with the thread 18 to advance and retract the plug in casing 10.
  • Shell 40 is rolled over to form a flange 44 which is adapted to ride in track 46 of retaining insert 50.
  • Insert 50 is of an insulating material such as plastic. Flange 44 secures shell 40 to insert 50 while permitting rotation between these two members.
  • Insert 50 has a plurality of holes 52 formed therethrough which holes correspond in number to the holes 22 and each of which is adapted to contain a pin means 54.
  • the forward portion of insert 50 has a slightly extending projection 56 in the area of each of the holes 52. The function of these projections will be described shortly.
  • Each of the pins 54 includes as part thereof a low-pass filter element 58.
  • These filter elements are of a standard type available from a variety of manufacturers.
  • the outer shell of each filter 58 is of conductive material and serves as one terminal of the device.
  • An electrical signal is applied to a pin 54 through wire 60 which is secured to the pin in a standard fashion.
  • the final element of plug I2 is resilient grommet 62.
  • Casing may be made from an aluminum impact blank which is impact forged within a die through the use of a highpressure press. Holes 22 may then be drilled in bulkhead to complete the operation. The desired ground plane may thus be secured in a simple and inexpensive manner.
  • casing 10 has served as part of the male portion of the connector
  • casing 10 could serve as the female portion of the connector if suitable elements are provided in casing 10 to make electrical contact with the far end of pins 54, and if other minor modifications were made in the elements 10 and 12.
  • the invention has been shown and described with filter elements in the pins 54, the invention would be equally applicable in any situation where pins 54 contain electrical elements which require that a reference potential be applied to this outer shell.
  • a filter connector comprising in combination, a hollow casing of an electrically conducting material having forward and rearward face surfaces with at least one cavity at each of said opposite face surfaces thereof; anelectrically conductive bulkhead forming an integral part of said casing, said bulkhead being positioned transversely between the cavities in said casing; and a plurality of holes formed in said bulkhead; elongated electrical contacts in at least some of said holes, said contacts each having a telescoping forward portion for engagement with a mating contact, a rearward terminalportion adapted for attachment to a flexible conductor, and an intermediate portion comprising an electrical filter assembly; with an annular groove around the contact between the rearward terminal portion and the filter assembly thereof, and contact retention means positioned wholly within the cavity at the rearward face of the casing and spaced rearwardly from the bulkhead thereof; the filter assembly including a smooth cylindrical exterior conductive surface extending forwardly from said annular groove through the transverse metal bulkhead of the casing, with a spring clip of thin, resilient electrically conducting material mounted within each of
