Definitions

  • This invention relates to an electrical connector assembly employed to make electrical connections in a plurality of electrical signal lines in which the impedance of the signals transmitted through the connector varies insignificantly from the impedance of the interconnected signal lines and more particularly the electrical connector embodying this invention is intended for use in making a right angle interconnection between two orthogonal conductor arrays such as two printed circuit boards or a printed circuit board and a flat transmission cable.
  • U. S. Patent 4,762,500 and U. S. Patent 4,747,787 depict electrical connectors intended for the impedance matched electrical interconnection of a plurality of circuits, either on a pair of printed circuit boards or between a transmission cable and a printed circuit board.
  • These connectors employ a central ground bus having a plurality of receptacle signal terminals located in parallel rows on opposite sides of the central ground bus. Both the receptacle terminals and the ground busses of mating connector halves are fully mateable so as to maintain the same impedance between the two connectors.
  • Each connector generally employs microstrip transmission principles to establish an interconnection, thus minimizing changes in impedance between the incoming component, either a cable or a printed circuit board, and the outgoing component, again either a cable or the circuits on a printed circuit board.
  • U.S. Patent 4,695,106 and U.S. Patent 4,762,500 in particular disclose electrical connectors for making a plurality of electrical connections between multiple signal lines on two orthogonally oriented printed circuit boards.
  • the present invention consists in an electrical connector as defined in claim 1.
  • the present invention consists in an electrical connector as defined in claim 3.
  • the present invention consists in an electrical connector as defined in claim 6.
  • EP-A-0 374 307 which is comprised in the state of the art by virtue of Article 54(3) EPC discloses a connector for printed circuit boards, in which signal contacts arranged in at least one row are positioned adjacent to respective discrete ground contacts, separated from the signal contacts by walls of the connector housing.
  • the ground contacts have spring members which urged them against said walls.
  • the preferred embodiment of the present invention which is disclosed herein comprises a practical and manufacturable electrical connector which can be used to interconnect circuits having an impedance of 50 ohms and the connector will remain substantially transparent, thus having little or no affect on the signals transmitted through the connector.
  • the electrical connectors embodying this invention provide a means for maintaining the positional relationship between signal terminals and a parallel ground bus through a right angle without introducing significant differences in the impedance of signals transmitted through the electrical connector.
  • the transmission of relatively high speed signals between two orthogonally oriented arrays of signal lines can be accomplished by an electrical connector having a microstrip transmission configuration.
  • One or more rows of signal contacts can be positioned adjacent a ground bus to transmit signals in such a manner.
  • the signal contacts and the ground bus each have a right angle bend intermediate the ends when orthogonally oriented signal arrays are to be interconnected.
  • the signal contacts are positioned within cavities in an insulative housing and the ground bus is positioned within a slot adjacent the row of cavities. In order to maintain the required spacing between signal contacts and the ground bus for microstrip signal transmission, each is urged toward the other.
  • the signal contacts can be urged toward the ground bus, for example by employing a resilient tab engaging the housing to urge the signal contact toward the ground bus.
  • a ground bus formed of two components can be employed with one ground bus component being urged toward the adjacent signal contacts by engagement with the other. If the ground bus is positioned equidistant between two rows of signal contacts, each ground bus could employ a protrusion engaging the corresponding protrusion on the other ground bus component so that each of the two ground bus components can be urged toward the signal contacts most closely adjacent that ground bus component.
  • the signal contacts and the ground bus are separated by an internal dielectric wall.

Note that the upper signal contacts 70 are urged downwardly, as shown in Figure 4, while the lower signal contacts 80 are urged upwardly toward the ground bus 90. Signal contacts also have right angle bends 78,88 located intermediate their ends.
