FIGURES 14 and 15 are perspective views of Figure 13 in an assembled form.
FIGURE 16 is a perspective view of the plug connector of Figures 13-15 in a completed form .
As shown in Figure 1, a multilayer circui$ board 10 has areas 12 in which matrices of electrical receptacle contacts 14 are disposed .
Connector-receiving members 16 are secured in position on board 10 via bolts 18. Spaced projections 20 are located along the inside surfaces of the tops and bottoms of members 16, forming channels in which electrical plug connectors 22 are latchably secured by flexible latch members 24 engaging surfaces 26 in openings 28 of members 16 as shown in Figures 8 and 9. This enables a front section of connectors 22 to be positioned through front openings 30 in members 16 so that tab contact sections 32 and 34 of connectors 22 can be electrically connected with respective receptacle contacts 14 In areas 12.
Figures 2 through 9 illustrate electrical plug connector 22 in greater detail. Contact-carrying member 36 is molded from a suitable dielectric '7~3~
material and has spaced recesses 38 located in one surface thereof.
Oblong projections 40 are located in each of recesses 38. Recesses 38 are disposed along member 36 in series of three recesses as illustrated in Figure 6. Circular projections 42 extend outwardly from the bottom surface of member 36 at spaced intervals therealong.
Signal contact members 44 are stamped and formed from suitable metal stock and they include contact sections 32, central sections 46 having oblong holes 48 therein, and conductor-connecting or ferrule sections 50.
Each of contact sections 32 has a double layer of metal which are maintainecl in spaced relationship with one another by inwardly-directed projection 52. Central section 46 is planar and is disposed in a respective recess 38 of contact-carrying member 36 with oblong projection 40 extending through oblong hole 48. When signal contact members 44 are secured in position in recesses 38 of contact-carrying member 36 via the outer ends of oblong projections 40 being enlarged by the application of pressure or heat, contact sections 32 extend outwardly from the front end of member 36 along the longitudinal axis thereof whilè conductor-connecting sections 50 extend outwardly from the back end of member 36 along the same plane containing recesses 38.
A ground contact member 54 has an elongated planar section 56 along which are disposed holes 58 for engagement with circular projections 42 when planar section 56 is disposed agains-t the bottom surface of contact-carrying member 36 whereafter the outer ends of projections 42 are enlarged by the application of pressure or heat thereby securing ground contact member 54 onto member 36. Adjacent the outer contact sections of the series of signal contaçt sections 32, ground contact sections 34 extend --L~--37~
outwardly from ground contact member 54 in the same manner as contact sections 32 and they have the same configuration as contact sections 32 so that ground contact sections 34 are disposed centrally of member 36 thereby beiny in longitudinal alignment with contact sections 32.
Conductor-connecting sections 60 extend outwardly from planar section 56 of ground contact member 54 and are located in the same plane as section 56 so that they extend outwardly from the back end of member 36.
As can be discerned, when signal contact members 44 and ground contact member 54 are secured in position on contact-carryin~ member 36, an electrical contact assembly is formed with contact sections 32 and 34 disposed centrally of the front end of contact-carrying member 36 and in alignment along member 36. Ground contact sections 34 are disposed adjacent the outer contact sections of the series of three si~nal contact sections 32 ar-d this disposition of contact sections 32 and 34 takes place along the entire length of contact-carrying member 36. The arrangement of signal contact sections and ground contact sections can be in any manner as desired with ground contact sections 34 on each side of onë or more signal contact sections 32 to make certain that optimum isolation of the signal information being processed along signal contact sections 32 takes place.
Conductor-connecting sections 50 and 60 are laterally spaced with respect to one another as shown in Figure 3 and each conductor-connecting section 50 is centraliy spaced with respect to conductor-connecting sections 60 on each side thereof as shown in Figures
3 and 6.

Contact-carrying member 36 spaces the signal contact members 44 relative to each other and signal contact members ~4 relative to ground contact member 54.
Signal conductors 62 of three-lead coaxiai cables 64 are disposed in the respective conductor-connecting sections 50 of signal contact members 44 while ground ur drain conductors 66 of each of cables 64 are disposed in respective conductor-connecting sections 60 immediately below and to each side of conductor-connecting sections 50. Each cabie 64 has a conductiYe coated plastic outer conductor surrounding the insulative sheath 68 covering signal conductors 62 which is electrically connected with a pair of drain conductors 66 thereby forming the three-lead coaxiai cable 64 which also includes outer dielectric jacket 70. Signal conductors 62 and drain conductors 66 are secured in conductor-connecting sections 50 and 60 in accordance with conventional crimping practices thereby terminating signal conductors 62 in respective conductor-connecting sections 50 of signal contact members 44 and drain conductors 66 in respective conductor-connecting sections 60 of ground contact member 54. It is -to be noted that conductor-connecting sections 60 are in a modified figure eight configuration to position drain conductors 66 from adjacent cables therein.
If desired, signal conductors 62 and drain conductors 66 can be electrically connected to conductor-connecting sections 50 and 60 respectively by the use of a laser to laser-weld the conductors to ~he conductor-connecting sections.
After conductors 62 and 66 of cables 64 have been terminated to respective contact members 44 and 54, the terminated assembly is positioned in a mold which includes cable-positioning members so that t~

dielectric housing 72 of suitable dielectric material is molded onto contact-carrying member 36 including the parts of the signal and ground contacts secured thereto and the terminations of cables 64 to conductor-connecting sections 50 and 60. Openings 73 are formed in housing 72 due to the cable-positioning members. Housing 72 also covers the inner parts of contact sections 32 and 34 as shown in Figure 5, and also covers sections of cables 64 to space and support them and provide strain relief therefor. Housing 72 also environmentally seals the terminations, stabilizes the contact sections and supports them, and polarizes plug connectors 22 via flexible latch members 24 because one of them is thicker than the other.
The dielectric constant of the material of contact-carrying member 36 and housing 72 is substantially the same as that of the cables to maintain the integrity of the signals being transmitted along the cables and the contact members.
Flexible latch members 24 are formed as integral latch members during the molding the housing 72 and each latch member includes a stop surface 74 which engages against the inside surface of connector-receiving member 16. Each of flexible latch members 24 includes a front leg 76 and a rear leg 78 which are flexed inward!y when plug 22 is inserted within connector-receiving member 16 between spaced projections 20. When stop surfaces 74 of latch members 24 engage the inside front surface of connector-receiving member 16, latch members 24 flex outwardly with front legs 76 extending into openings 28 with latching surfaces 80 engaging surfaces 26 thereby latchably securing plug connector 22 in position in connector-receiving member 16 as shown in Figure 9.

Arcuate projections 82 are located on housing 72 in alignment Witil legs 76 and 78 to prevent latch members 24 from being overstressed when plug connectors 22 are moved into connector-receiving member 16. As shown in Figure 7, latch member 24 at the left side is thicker than latch member 24 on the right side and spaced projections 20 are accordingly spaced along connector-receiving member 16 thereby defining a polarizing arrangement to polarize the insertion of plug connectors 22 within connector-receiving member 16 to make certain that contact sections 32 and 34 are properly electrically connected with respective electrical receptacle -contacts 14.
Whereas three-lead coaxial cables 64 have been disclosed as being terminated to the conductor-connecting sections of signal contact members 44 and ground contact member 54 of the connector assembly, a three-lead transmission cable can also be used wherein a signal conductor is isolated from drain conductors on each side thereof. The typical assembly utilizing the present invention is for ends of cablex 64 or transmission cables to be terminated to electrical plug connectors 22 for transmitting electrical signals with high reliability and uniformity from a transmission source to a receiving member or vice versa.
Figures 10 through 12 illustrate an alternative embodiment of the electrical contact assembly wherein contact-carrying member 36A includes a conductor-positioning section 84 along which are channels 86 and 88.
Channels 86 are centrally aligned with recesses 38A in which signal contact members 44A are secured via oblong projections 40A so that signal conductors 62 of cables 64 are positioned in channels 86 and in engagement with respective conductor-connecting sections 90 of signal contact members 44A which are engaged with conductor-positioning section 84. Ground conductors 66 of cables 64 are positioned along channels 88 on each side of a respective channel 86 and in engagement with a conductor-connecting section 92 of ground contact member 54A secured onto contact-carrying member 36A via projections 42A with section 92 engaged with section 84.
Conductors 62 and 66 are welded respectively to conductor-connec-ting sections 90 of contact members 44A and conductor-connecting section 92 of contact member 54A, preferably by laser-welding techniques. Housing 92A
is molded onto the terminated contact assembly.
Figures 13-16 illustrate a further embodiment of the electricai contact assembly wherein contact-carrying member 36B includes conductor-positioning section 94 along which channels 96 are located in one side and channels 98 are located in the other side. Channels 95 are in communication with recesses 100 and both of channels 96 and 98 include beveled surfaces to guide signal conductors 62 and ground conductors 66 of cables 64 respectively along channels 96 and 98.
Signal contact members 102 are stamped and formed from pre-rolled or pre-millecl metal stock with contact sections 104 being thicker than bent sections 106 which are thicker than central or mid sections 108 and ferrule sections 110. Mid sections 108, part of bent sections 106, and ferrule sections 110 of signal contact members 102 are disposed in respective recesses 100 with oblong projections 112 in recesses 100 extending through oblong holes 114 of mid sections 108 and ferrule sections being disposed be-tween aligning projections 116 at the inner ends of recesses 100.
Aligning projections 116 align ferrule sections 110 in recesses 100 so that slots 118 in ferruie sections 110 are in alignment with respective channels _g _ '7~3~

96, slots 118 having a width slightly less than the diameter of signal conductors 62 so that they can be force-fitted thereinto. After signal contact members 102 are positioned in recesses 100, projections 112 are mechanically or thermally deformed thereby securing contact members 102 in position with contact sections 104 extending outwardly from and being centrally aligned along the front surface of contact-carrying member 36B.
Ground contact member 120 is stamped and formed from pre-rolled or pre-milled metal stock with contact sections 122 being thicker than bent sections 124 which are thicker than central section 126 which has a folded-over section 128 in which slo-ts 130 are located . Slots 130 are in communication with respective openings 132 in bight section 134 which neck down as they merge with slots 130. The width of slots 130 are slightly smaller than the diameter of conductors 66 so that they can be force-fitted thereinto .
Planar section 126 has holes 136 through which circular projections 138 on contact-carrying member 36B extend when ground contact member 120 is mounted thereon. Projections 138 are mechanically or thermally deformed thereby securing contact memher 120 on member 36B with contact sections 122 extending outwardly from and being centrally aligned alons3 the front surface of member 36B so that contact sectiorls 104 and 122 are in alignment. Planar section 126 also has openings 140 therein which are designed in size and location to tailor the impedance of the assembly to approximate the characteristic impedance of the cable.
After contact members 102 and 120 have been secured to member 36B, conductors 62 and 66 of cables 64 are guided by channels 96 and 98 so as to be positioned along slots 118 and 130 of respective contact members 102 3'7~5~

and 120. These conductors are then force-fitted into slots 118 and 130 whereafter they are laser welded in position in accordance with conventional welding practices thereby forming the ele,-trical contact assembly as shown in Figures 14 and 15.
Dielectric housing 142 as shown in Figure 16 is molded onto the contact assernbly in the same manner as that of housing 72 and housing 142 has a single opening 144 to minimize engagement with cables 64 to prevent distortion thereto. Integral flexible latch members 146 of different widths axtend outwardly from the sides of housing 142 and arcuate projections 148, 150 are located on housing 142 and latch members 146 to prevent overstressing of latch members 146. Housing 142 otherwise functions the same as housing 72 and the dielectric constant of the material of member 36B and housing 142 is substantially the same as that of cables 64 to maintain the integrity of the signals being transmitted along the cables and the plug member.
