  • This connector has a pair of connector portions assembled in an operative relationship and each comprising a core formed of a dielectric material around which is wrapped a flexible circuit.
  • the flexible circuit is provided on each side with an array of conduction tracings adapted to interconnect an array of conduction paths on a daughter board with corresponding ones of an array of conduction paths disposed on a mother board, when the daughter board is inserted between the connector portions.
  • a pair of springs is provided to impose biasing forces on the flexible circuit to ensure electrical contact between each of the set of conduction tracings thereon and the corresponding conduction paths on the two boards.
  • the disadvantages of this arrangement are that it is rather complex and is difficult to assemble.
  • an electrical connector means for connecting a first circuit board to a second circuit board substantially at right angles to each other, in which a flexible circuit means having conductors at the surface thereof is provided to interconnect conductors of said first circuit board with conductors of said second circuit board, characterized by a housing adapted to be secured to said second circuit board, said housing defining an open ended chamber having first and second opposed side walls and an end wall which is remote from the open end and which has a slot therein for receiving an edge of said first circuit board, and an elastomeric member, having a recess in alignment with said slot, and disposed in said chamber such that part thereof projects out of said open end, said flexible circuit means being wrapped around said elastomeric member and having first and second free ends each extending at least partially across said recess and also having an intermediate portion extending over the projecting part of said elestomeric member, and first and second portions of said flexible circuit means being trapped between said elastomeric member and said first and second side walls, where

  • a plurality of solid portions 22 spaced along and at the ends of the housing 15 define the ends of the chambers 17.
  • the top of each chamber 17 extends up to the slot 16 such that the edge of the daughter board 12 may be inserted into the top portion of each chamber 17.
  • the daughter board 12 penetrates through the slot 16 and into each respective chamber 17 until further penetration is stopped by the top surface of the solid portions 22.
  • the solid portions 22 not only serve as stops for the edge of the daughter board 12, but also receive a plurality of screws 25 for connecting the mother board 14 to the connector housing 15, as will be explained.
  • Figs. 3, 4 and 5 are simplified cross sectional views of the connector assembly 10 showing how the connector 10 may be assembled for making electrical connections between the daughter board 12 and mother board 14.

  • the lower portion 30 of each elastomeric member 28 has two semi-cylindrical portions 35 and 36 separated by a channel 33.
  • the two semi-cylindrical portions 35 and 36 are axially parallel to each other and are substantially equal in all dimensions including the extension of each below the bottom 39 of the connector housing 15.
  • the semi-cylindrical portions 35 and 36 of the elastomeric members 28 will be compressed and deformed as the mother board 14 is fastened to the connector housing 15, as will be explained.
  • the elastomeric members 28 may be fabricated of compressible silicone material available from the General Electric Company under the designation SE6140 and having a durometer rating of 40.

  • Fig. 4 illustrates a daughter board 12 having one edge inserted into the slot 16 of the connector housing 15 and extending into the slot 29 of the elastomeric member 28.
  • the free-ends 31 and 32 are displaced downwards and trapped between the sides of the daughter board 12 and the walls of the slot 29 as the daughter board 12 is inserted into the slot 29.
  • the width of the slot 29 is at least ten per cent less than the thickness of the daughter board 12 such that, as the edge of the daughter board 12 is inserted into the slot 29, the elastomeric material is compressed making a tight connection between the sides of the daughter board 12 and the free-ends 31 and 32.
  • a wiping action between the conductors on the flexible circuit and the edge connector pads of the daughter board 12 is also provided as the edge of the daughter board 12 is inserted into the slot 29.
  • the mother board 14 is connected to the housing member 15 by the plurality of screws 25 which pass through holes 38 in the mother board 14 and are screwed into the solid portions 22 of the housing member 15 (see Figs. 1 and 2).
  • the semi-cylindrical portions 35 and 36 of the elastomeric members 28 are compressed against the sides of the chamber 17 and the top of the mother board 14.
  • the semi-cylindrical portions 35 and 36 not only become compressed as they are forced into the smaller volume of the chamber 17, but they also undergo deformation into the volume of the channel 33.

  • the flexible circuit 34 has etched, gold plated copper conductors 45 on the extending panels 40 and 41 extending partially into the connecting strip 42 and ending at reference numbers 46 and 47. This allows a separate circuit on each side of the daughter board 12 to be connected to a separate circuit on the mother board 14, as will be discussed in connection with Fig. 7. It will be understood that, rather than a single integrated structure as seen in Fig. 6, flexible circuit 34 could be replaced with separate and unjoined individual flexible circuits, each having paired extending panels 40 and 41 and each for being placed around one of the elastomeric members 28 in one of the chambers 17.

  • the edge connector pads 52 of the circuit on side 50 of the daughter board 12 are connected to the connector pads 53, and the separate edge connector pads (not shown) on side 51 are connected to the connector pads 55.
  • the flexible circuit 34 around the elastomeric members 28 includes gold plated conductors 45 on each of the extending panels 40 and 41.

  • the lower portion 30 of each elastomeric member 28 has two semi-cylindrical portions 35 and 36 separated by a channel 33.
  • the two semi-cylindrical portions 35 and 36 are axially parallel to each other and are substantially equal in all dimensions including the extension of each below the bottom 39 of the connector housing 15.
  • the semi-cylindrical portions 35 and 36 of the elastomeric members 28 will be compressed and deformed as the mother board 14 is fastened to the connector housing 15, as will be explained.
  • the elastomeric members 28 may be fabricated as described previously with regard to Fig. 3.

  • the semi-cylindrical portions 35 and 36 not only become compressed as they are forced into the smaller volume of the chamber 17, but they also undergo deformation.
  • the semi-cylindrical portions 35 and 36 deform into the volume of the lower, widened sides of the chamber 17 and into the volume of the channel 33.

  • the edge connector pads 52 and the printed circuit connector pads 53 and 55 are .050 inches wide on .100 inch center-to-center spacing.

  • the rounded end extends below the bottom 39 of the connector housing 15 such that the elastomeric members 28 will be compressed when the mother board 14 is fastened to the connector housing 15.
  • the edge of the daughter board 12 is inserted into the slot 29 as shown in Fig. 13, the elastomeric material is compressed making a tight connection between the sides of the daughter board 12 and the free-ends 31 and 32.
  • a wiping action is also provided as the edge of the daughter board 12 is inserted into the slot 29.

  • the mother board 14 is drawn into tight engagement with the connector housing 15, the lower portions 30 of the elastomeric members 28 are compressed, tightly trapping the flexible circuit 34 between the elastomeric members 28 and top of the mother board 14.
  • Fig. 15 is a perspective view of the connector 10 ⁇ of the present invention represented in a similar manner as the embodiments shown in Figs. 7 and 11 and with the same reference numerals.
  • the drawback of this design is in that most of the pressure of the semi-cylindrical portions of the elastomeric member 28 impinges upon the non-conducting strip of the mother board 14 defined by the lines 46 and 47, and not against the connector pads 53, 55.
  • the disclosed embodiments of the present invention are inexpensive in that pins and pin connections are not required. Furthermore, electrical connections will be made even if the connector assemblies 10, 10′ or 10 ⁇ and/or the flexible circuit 34 therein, are slightly skewed or offset.
  • the connector assemblies 10, 10′ and 10 ⁇ also provide for right angle contact between a mother board 14 and daughter board 12, which does not require expensive, often unused, mating connectors on a mother board, allows for right angle contact between two circuits on the mother board 14 with two circuits on the daughter board 12, allows for the changing of the daughter board 12 without removal of the connector assembly, and provides for ease of interconnect changes by revising the conductor pattern on the flexible circuit 34.
  • a connector assembly need not be added to the mother board 14 until it is desired to add a daughter board 12.
  • the connector assemblies 10, 10′ or 10 ⁇ need not be added to the mother board 14 in anticipation of additional daughter boards 12 (such as additional memory boards) being added at a later time, but may be quickly and easily added with only a screwdriver at the time additional daughter boards 12 are actually added.
  • a connector assembly 10, 10′ or 10 ⁇ may be attached to both major surfaces of the mother board 14 to provide for the connection of daughter boards 12 on each side of the mother board 14, if desired.
