  • the printed circuit board 16 supporting on its upper surface a mating connector 14 for receiving the connector 10 whereby discrete elements of the mating connector and printed circuit board may interconnect with discrete conductive elements of the cable within the connector.
  • the mating connector 14 is formed with front and rear faces 28 and 30, end faces 32 and 34, and top and bottom surfaces 36 and 38.

  • the connector 10 itself is formed of a plurality of connectable component elements formed of an electrically insulative plastic material.

  • the connector of the present invention could be used in any vertical, horizontal, or angular orientation
  • the housing 62 is formed of a block-like member with front and rear faces 76 and 78, end faces 80 and 82, and a lower surface 44 and an upper internal surface 84 is fabricated into a unitary component member as by molding.
  • the housing includes inwardly projecting shelf-like blocks 88, the upper surfaces of which constitute the upper internal surface 84 of the housing. These blocks extend inwardly toward the longitudinal central plane of the connector and toward each other to form a central slot 90 of such size as to receive a ground contact or bus 72.
  • the bus is a blade-like electrically conductive member formed of an electrically conductive material, preferably metal.
  • ground bus 72 is formed in a tight U-shaped configuration with its free edges 92 extending upwardly and outwardly, flared to a limited degree, for assisting in locating and receiving ground wires 20 of the flat cable 12.
  • the lower portion of the ground bus 72 is adapted to be received downwardly into the central slot 90 of the housing and to mechanically and electrically receive selected conductive wires 20 of the flat cable, specifically, those wires of the cable intermediate the signal wires which function as electrical grounds.
  • the bus 72 is shiftable within slot 90 from the position shown in Figure 5 to the position shown in Figure 6.
  • the signal contacts are formed of an electrically conductive material, preferably metal. They include posts 96 of a rectangular cross-sectional configuration over the majority of their lower lengths. Their upper extents 98 are rectangular in cross-section but enlarged with respect to their lower extents for being received by, and supported upon, the upper surfaces 84 of the blocks 88. Their upper edges are provided with notches 102, perpendicular with respect to the longitudinal central plane of the connector. Each notch has a U-shaped or semicircular lower extent for receiving a signal wire 22 or 24 of the flat cable.
  • ground contact wires 20 and signal contact wires 22 and 24 are thus adapted to be received respectively by the ground contact bus 72 and signal contact 60 for mechanically and electrically coupling the wires of the cable with the electrically conductive connectors of the mating connector and, hence, to the traces of the printed circuit board, all in a particular predetermined orientation.
  • the signal wires 22, 24 and the ground wires 20 can be mechanically and electrically secured to associated signal contacts 60 and ground bus 72 by first bending the signal wires of a stripped cable 12 in the manner shown in Figure 4B.
  • a bending fixture suitable for precisely bending the signal wires 22, 24 is illustrated in Figure 4A. Only a portion of the bending fixture is shown in Figure 4A and it will be understood that this fixture constitutes only one apparatus for deploying the signal wires 22, 24.
  • This fixture includes a number of relatively tall positioning shims 284, each having a notch 298 with a width substantially equal to the thickness of flat cable 12. Notches 298 in the plurality of positioning shims 284 are aligned.
  • Positioning shims 284 are separated by signal wire shims 286 and ground wire shims 288.
  • Each ground wire shim 288 has a ground wire notch (not shown), aligned with notches 298, and having a greater depth.
  • the upper edge 212 of signal wire shims 286 are lower than notches 298.
  • a plurality of bending fingers 260, 272 are aligned with the channels formed between tall positioning shims 284 and above signal wire shims 286. No bending fingers are aligned with ground wire shims 288. Bending fingers 260, 272 are staggered and are shiftable towards and away from each other.
  • the ground wires 20 can be crimped between the flared ends 92 of ground bus 72 in the manner shown in Figure 5. Note that the flared ends 92 are accessible from the sides with the ground bus in the position shown in Figure 5. Once the ground wires 20 have been crimped to the ground bus 72, the ground bus is shifted within slot 90 from the position shown in Figure 5 to that shown in Figure 6. Movement of the ground bus 72, to which the cable 12 is now attached will bring the bent signal wires 22, 24 into proximity with the signal contacts 60.
  • the front and rear faces 76 and 78 of the housing are formed with downwardly projecting legs 104.
  • downwardly projecting legs 106 are formed in proximity to the ends of the housing. These downwardly projecting legs extend generally peripherally around the housing and are arranged to be slid over the front and rear faces 28 and 30 and ends 32 and 34 of the mating connector 14.
  • Portions of the top external surface and faces of the housing are formed as cutaways 108 so as to receive the front and rear cover halves.
  • the cover halves are similarly shaped, each with an upper portion 110 positionable proximate the upper external surface of the housing and with two downwardly extending pair of parallel legs 112 and 114.
  • the interior legs 112 are the shorter legs with their interior faces located closer to the longitudinal central plane of the connector. Their lower surfaces are supported by an upper internal surface of the housing.
  • the exterior legs 114 are the longer legs with their interior surfaces spaced from the interior legs to create spaces 116 therebetween.
  • the front and back cover halves are essentially symmetrical with respect to the longitudinal central plane of the connector except for a strain relief recess 118 and a mating strain relief projection 120 adjacent to their upper interior surfaces for receiving and holding the cable 12 to preclude its movement from the connector during operation and use as might occur through inadvertent pulling.
  • Beneath the strain relief elements of the cover halves are additional recesses 122 for accommodating the upper extents of the signal contact 60 and bus 72 and the lower stripped ends of the wires of the flat cable.
  • the end of the flat tranmission cable supported by the connector 10 is stripped to such an extent that its non-stripped portion will be contacted by the strain relief elements of the cover halves for providing the desired restraint from movement.
  • the area of the flat cable beneath the strain relief elements will be stripped to such an extent that the stripped ends are located within the additional recesses 122 of the cover halves.
  • the lower ends of the exterior legs are formed with projections 124 extending exteriorly away from the longitudinal central plane of the housing.
  • the projections include essentially horizontal, upwardly facing, ledges 126 which are employed for fixedly positioning the housing with respect to the printed circuit board during operation and use.
  • Between the interior and exterior legs are the upwardly extending spaces 116 to allow for a limited degree of movement of the exterior legs which, due to their resiliency, accommodate the attachment and removal of the connector from the printed circuit board.
  • the last component elements of the connector are two similarly configured side latches 68 and 70.
  • the side latches have lower surfaces 130 supported upon the upper surface of the printed circuit board 16.
  • Formed on the lower surface of each side latch is a downwardly projecting attachment button 132 to be received by apertures 134 in the printed circuit board to which the connector is to be secured.
  • each button 132 is provided with an enlarged area with an upwardly facing abutment surface and an axial cutout 136 whereby the lower end of the buttons may be contracted, forced through holes in the printed circuit board, and released to provide a secure mechanical attachment to the printed circuit board for the side latches and hence for the connector and flat cable. Contraction of a button 132 at its cutout 136 will allow removal of its side latch from the printed circuit board.
  • legs 138 Upwardly extending from the base portions of the side latches are legs 138 formed with projections 140 extending inwardly toward the longitudinal centerline of the housing.
  • the projections include downwardly facing, essentially horizontal ledges 142 which are employed to receive and hold the upwardly facing ledges 126 of the cover halves. The positioning of the cover halves and housing over the mating connector will allow the cover halves to be secured with respect to the side latches for holding the connector in place with respect to the mating connector and printed circuit board.
  • each of the first or interior legs of each cover half have face projections 144 in the plane of their leg extending longitudinally away from each other and toward the ends of the housing. These projections, a total of four in number, are received in correspondingly shaped face recesses 146 in the front and rear faces of the housing. When coupled, the projections and recesses preclude upward and downward movement of the cover halves with respect to the housing. Similarly, the ends of each of the cover halves have outwardly extending end projections 148, four in number, facing away from each other and toward the ends of the housing. These projections are receivable in correspondingly shaped end recesses 150 in the housing. When the cover halves are coupled to the housing, these projections and recesses will preclude lateral movement of the cover halves in a horizontal plane with respect to the housing.
  • the coupling of the front and rear cover halves 64 and 66 with respect to the connector housing 62 is effected by simply holding the cover halves parallel with each other adjacent to the flat cable after the stripped cable ends have been coupled to the signal contacts 60 and the ground bus 72. While maintaining this parallel relationship, the halves are moved either simultaneously or sequentially toward the flat cable 12. The halves with their end projections 148 will readily snap into the end recesses 150 for proper operational positioning of the cover halves with respect to the housing 62. Removal of the cover halves involves urging the upper portions of the housing outwardly away from each other in the plane of the longitudinal central plane. This action allows the end projections 148 to clear the end recesses 150 as the halves are pulled away from the flat cable and housing 62 by a motion reserved with respect to the motion which effected their coupling.
  • the front face 28 of the mating connector 14 is provided with two upwardly extending spaced parallel plugs 156.
  • the front face of the connector housing 62 is formed with two downwardly extending spaced parallel slots 154.
  • the plugs and slots are equally spaced and of substantially the same width to allow the mating of the connector housing 62 with the mating connector. These plugs and slots are located on one face only of the connector housing and mating connector and are in mutually restrictive locations to preclude the improper positioning of the connector housing 62 and connector 10 with respect to the mating connector 14. As a result, it is impossible to couple the connector 10 and mating connector 14 in a reverse orientation.
  • every other connector wire 20 of the flat cube 12 is a ground for being received by the ground bus 72.
  • Every intermediate connector wire 22 and 24 of the cable is adapted to carry a signal from the cable to the printed circuit board.
  • every signal wire of the cable must be bent outwardly toward an appropriate signal contact 60 on one side or the other of the longitudinal central plane.
  • appropriate wires of the flat cable may be coupled with appropriate traces of the printed circuit board for accommodating and effecting the intended electronic function of the connector.
  • the housing with its signal contact connector wires of the cable in proper position, may then be heated as through radio frequency energy to liquify the solder material between the signal contacts and signal wires to make secure solder connections therebetween.
  • the signal connector wires of the cable are bent from the vertical orientation slightly less than a full 90 degrees. By bending them at about 70 degrees, their exterior portions remote from the bends will contact an exterior portion of the signal contacts, the edges of the signal contacts remote from the longitudinal central plane. When urged downwardly during coupling, the ends of the signal wires will be forced slightly upwardly by the signal contacts to beyond the desired 70 degrees for insuring complete contact between all of the signal wires and their signal contacts. The deflection upwardly may be between about an additional 5 and 20 degrees, but still preferably below the horizontal or 90 degree orientation. This deflection of the wire insures a secure physical contact between each signal wire and its associated signal contact prior to soldering.
  • the diameter of the U-shaped slot 102 of the signal contacts 60 is equal to or preferably slightly greater than the diameter of the conductive signal wires 22 and 24 of the flat cable 12.
  • the soldering may thus effect an encapsulation of at least about 270 degrees of the wires, for forming a mechanical bond as well as an electrical coupling.
  • the solder material will often totally encapsulate the entire cross-section of the signal wires along their entire lengths. Contrary to previous thoughts, a mechanical wedging action between the wire and slot to be soldered has been found to be unnecessary, and hence the diameter of the wire 22 or 24 is preferably not greater than the width of the slot or the diameter of its bight.
  • the solder material may be applied to the appropriate portion or portions of the signal contacts by any one of a plurality of techniques including plating, printing, silkscreening, dipping or inlaying.
  • the solder material is plated onto the upper end of the signal contact to at least cover the U-shaped bight.
  • the soldering may be enhanced by a commercial flux material provided onto the stripped wire ends.
  • the solder may be caused to reflow by any one of a plurality of methods of heating, including radio frequency, resistance, laser or vapor phase. Radio frequency is the preferred embodiment.
  • the coupling of the stripped wire ends to the signal contacts is effected by adhesion between the soldering material intermediate the wires and the signal contacts, the reflowing of the soldering material therebetween effecting the coupling. It should be further understood that the desired coupling may be effected by a wide range of adhesive coupling techniques.
