  • a connector must lie within a circuit board area of about 76.2 mm by 8.5 mm (three inches by one third inch).
  • the connector has 400 contacts arranged in six rows in a small area. As a result, the contact centers must be spaced apart along each row by about one millimeter, necessitating the use of very small contacts.

  • the method includes first, installing each said contact upper end portion into one of said housing holes so said upward-facing shoulder of said contact mount portion is spaced below the level of a corresponding one of said downwardly-facing lower surface regions to leave a space between them as seen in a side view, temporarily installing at least one push bar between a plurality of said upward-facing shoulders and said housing surface regions, so said push bar can engage both said upward-facing shoulders and said downward-facing surface regions; with said mount portions lying above and aligned with said circuit board holes, pressing down against said upper housing and transmitting force via said upper housing from said lower surface regions through said push bar to said upward-facing shoulders, to simultaneously press down said mount portions into said circuit board holes, finaly removing said push bar from between said contact shoulders and said housing lower surface regions.
  • an aligner is pressed sidewardly against each contact lower portion to deflect it into alignment with a corresponding circuit board hole.
  • Each aligner is preferably in the form of a bar having a greater width than thickness.
  • the aligner bar is initially installed with its width vertical, and thereafter the aligner bar is turned so its width is horizontal to deflect apart adjacent contact lower ends.
  • the lower end portions of the contact once projecting from the lower surface of the circuit board, can be installed in a lower housing which has a tapered deflector projecting from its upper surface to deflect the tips of the contact slightly sidewardly into holes of the lower housing.

  • Each module 12 - 16 includes a module connector assembly 22 - 26 for interconnecting the modules to each other and to a connector 20 on the mother board.
  • Each of the middle module connectors 22, 24 includes upper and lower housings 30, 32 at opposite faces of the circuit board 34, and multiple contacts extending through the circuit board and into each of the housings 30, 32.
  • Each of the end module connectors 20, 26 has a connector housing on only one side of the corresponding circuit board.
  • terms such as “upper”, “lower”, “vertical”, etc. are used only to aid in the description of the invention, and the system can be used in any orientation with respect to gravity.
  • Fig. 2 shows an arrangement which includes only the mother board 18 and two of the modules 12, 16.
  • Fig. 3 illustrates an arrangement that includes only the two uppermost modules 14, 16 and their corresponding connector assemblies 24, 26. Any of the above arrangements and more complex ones can be used.
  • the connector assembly 24 includes upper and lower connector housings 40, 42 lying respectively against upper and lower surfaces 44, 46 of the circuit board 34.
  • a large number of contacts 50 are arranged in six rows 51 - 56.
  • Each contact has an upper end portion 60 that lies primarily within the upper housing 40, a lower end portion 62 lying primarily within the lower housing 42 and a mount portion 64 lying within a hole 66 of the circuit board in interference fit, or press fit therein.
  • the mount portion forms an upwardly-facing shoulder 78 which is used in installing the contact in the circuit board hole.
  • the holes 66 of the circuit board which lie in the six rows 51 - 56, are staggered, in that one column 70 of holes includes holes in only three of the rows (rows 51, 53, and 55) while the next adjacent column of holes 72 includes holes only in each of the other three rows (rows 52, 54, and 56).
  • a sectional view of the connector assembly may show only portions of contacts in only three rows, with corresponding portions of contacts in the other three rows being hidden.
  • Fig. 5 which shows two contacts 50A, 50B
  • a simple sectional view that would show all of contact 50B would show only part of the other contact 50A.
  • the upper end portion 60 includes a base-received part 70 that lies in interference fit with the walls of a hole 72 in the base 74 of the upper housing 40.
  • the upper end portion 60 also includes a beam 76 which can engage a contact of another connector assembly.
  • the upper end portion 60 also includes an unenclosed or bare part 80 which lies in the space 82 between the upper surface 44 of the circuit board and the lower surface portion 84 of the upper housing that lies immediately around the contact.
  • the space 82 has a thickness Y which is much more than the average thickness A of each contact end portion.
  • the contact also has a lower end portion 90 with a lower tip 92 lying within the lower housing 42 and a base-received portion 94 lying in interference fit with the walls of a hole 96 in the lower housing.
  • the interference fit between a contact mount portion 64 and a corresponding circuit board hole 66 is a high interference fit, in that this interference fit is the primary means for holding the contact in position, such as against upward and downward forces applied during mating and unmating from contacts of other connectors.
  • the center-to-center spacing of contacts along each row was one millimeter.
  • Each contact was constructed of sheet metal having a thickness of 0.15 mm (six thousandths inch) and a width B of 0.38 mm (fourteen thousandths inch). Yet, the insertion force required to push the mount portion 64 into the circuit board hole 66, (which was metal plated) was between 2.72 to 5.44 kg (six to twelve pounds).
  • a large number of contacts to be installed in a single row are formed simultaneously from a sheet of metal, with the mount portions 64 of all contacts bent to a "C" shape as shown in Fig. 7, and with the upper and lower end portions bent as shown.
  • Different positions of the contact end portions such as 60 with respect to the "C" shaped mount portion 64 can be utilized.
  • Figs. 5 - 7 show a latest and preferred position. As shown in Fig. 7, the contact upper end portion 60 extends from one side 67 of the upwardly-facing shoulder 78, while the space immediately above the other side 68 of the shoulder is unobstructed.
  • a bar portion of the width X lying over the shoulder will pres down against about two-thirds of the cross-section of the mount portion 64.
  • the row of contacts With the row of contacts still part of a single sheet by virtue of connector parts (not shown) connecting them to a carrier strip of the sheet metal, the row of contacts are inserted into the row of holes 72 (Fig. 5) in the upper housing 40, this requiring only moderate force, and with each contact being individually accessible, at least from the bottom of the contact. After the rows of contacts have been installed in the upper housing 40, the contacts are severed from the carrier strip. The contacts are now to be installed in tight interference fit with the circuit board holes.
  • Fig. 9A shows the connector assembly with the upper end portions 60 of the contacts installed in the upper housing 40, and with the contact lower end portions 62 extending down so their lower tips 100 lie at or slightly above the upper surface 44 of the circuit board 34.
  • each tip 100 lie substantially on the axis 110 of the corresponding hole.
  • the tips 100 are slightly spaced from the axis 110.
  • Applicant installs elongated aligners or aligner bars 120 between the contacts in adjacent rows such as 51 and 52, slightly above the tips 100 of the contacts.
  • Each aligner bar has a greater width W than its thickness T (Fig. 9B).
  • Each of the aligner bars is rotatable about an axis 114 extending along the length of the aligner bar and parallel to the contact rows. The aligner bars are initially installed in the orientation shown in Fig. 9A with their widths vertical. As shown in Fig.
  • the aligner bars are then rotated 90° so their widths are horizontal, and each aligner bar deflects a location 116 on the contact lower end portion 62 lying closer to the tip 100 than to the mount, so the tip lies aligned with the axis 110 of the cylindrical board hole.
  • a next step is to lower the upper housing 40 by a very small amount, so that the lower tips 100 of the contact actually lie within the board holes 66.
  • the aligner bars 120 are moved horizontally parallel to the lengths of the rows, to withdraw the aligner bars from between the contacts.
  • Fig. 9D shows the apparatus with the aligner bars removed, but with the contact lower tips 100 lying within the board holes 66 so the contact tips will remain in the board holes.
  • Fig. 9E shows a next step, which involves pushing down the upper housing 40 by a considerable amount (e.g. 12.7 mm (one-half inch)) until the contact mount portion lie substantially against the upper surface 44 of the circuit board, and ready to be inserted into the circuit board holes 66.
  • Fig. 9F shows a next step, where a large downward force F is applied to the upper surface 124 of the upper housing 40 to push down the upper housing 40.
  • the housing 40 presses down the push bars 102 - l06 which press down the mount portions 64 into the contact holes 66.
  • the upper housing 40 is preferably molded of a thermoplastic chosen to have a moderately high strength for a thermoplastic, but whose strength is low compared to that of common metals such as bronze or steel. If the entire downward force of perhaps 2.7 to 5.4 kg (six to twelve pounds) per contact had to be applied directly by the lower surface of the thermoplastic upper housing 40, then there could be high pressure on the lower surface of the thermoplastic upper housing 40 which might damage it and result in one or more of the contacts not being pressed reliably into a circuit board hole. Also, as shown in Fig.
  • the hole 72 in the housing base be considerably wider than the contact to enable a curved tip portion 130 to pass therethrough, which would result in only a small area of the housing pressing down against the shoulder 78 of the mount portion. There would even be danger that the C-shaped mount portion could be deformed into the housing hole 72.
  • the use of the push bars such as 106 enables the use of a harder material, such as steel than the thermoplastic material of the housing. Also, the push bar 106 can lie over most of the shoulder 78, except for one side from which the upper contact portion 60 extends, to provide a large area of contact. The downward force applied to the push bars, is applied through the upper housing 40, by a large force F (Fig.
  • the upper housing 40 is pushed down far enough until spacer legs 132 at the bottom of the housing lie substantially against the upper surface 44 of the circuit board.
  • the spacer legs 132 position the upper housing stably on the circuit board.
  • the upper housing 40 can be held down to the circuit board solely by the contacts, although separate fasteners can be used.
  • the lower housing has a base 140 with base holes 142 which receive the contact lower end portions. However, the contact lower tips 100 are offset from the base holes 142.
  • Applicant forms the lower housing 42 with tapered deflectors 144 extending upwardly from most of the housing upper surface 146 (the portion of the upper surface that lies between spacer legs 148 of the lower housing). As the lower housing 42 is moved upwardly, the contact tips engage inclined deflect surfaces 143 of tapered deflectors 144 and are deflected slightly to one side and into the base holes 142.
  • FIG. 9G shows the connector assembly 24 with all parts thereof installed on the circuit board 34.
  • the presser bars 106 are then removed by sliding them horizontally and parallel to the length of the contact rows, out of the space between the upper housing and the upper surface of the circuit board.
  • Fig. 9H shows the connector assembly 24 with all installing apparatus removed.
  • Fig. 15 is a simplified view of one apparatus 150 which can be used to insert and remove the push bars 102 - 104, and to insert, turn, and remove the aligner bars 120.
  • the apparatus includes a guide device 152 having three rectangular guideways 154 that can guide the push bars 102 - 106 to move them between the bottom of the upper housing and the shoulders of the contact mount portions. Each bar has a tapered forward end 156 to facilitate its insertion.
  • the guide member also has three cylindrical guideways 160 that each receives one of the alignment bars 120.
  • the rear end of each alignment bar is fixed to a cylindrical rod 162 that can slide and rotate within one of the cylindrical guideways 160.
  • the guide device 152 can slide up and down a short distance on a base 164 which guides the guide device 152 in vertical movement.
  • the base 164 has positioning devices 166 with pins 168 that can be received in corresponding holes 170 (Fig. 8) of the circuit board to accurately align the base 164 with the circuit board.
  • the upper housing 40 (Fig. 9A) with the upper contact end portions installed thereon, can be installed on the push bars 102 and alignment bars 120 by sliding the housing with contacts thereon horizontally over the bars.
  • the aligner bars 120 are then turned to the position shown in Fig. 9B.
  • the guide device 152 is moved downwardly a short distance such as several 0.025 mm (thousands inch), to the position shown in Fig. 9C, so the lower tips df the contacts enter the circuit board holes.
  • the alignment bars 120 (Fig. 15) can then be turned, or can be left in their position, and then pulled rearwardly in the direction R out of the guide device 152.
  • the guide device is then moved downwardly by a distance such as 12.7 mm (one-half inch), until the contacts and upper housing are at the position shown in Fig. 9E. If the guide device 152 is not to be used to apply large downward pressure to the upper housing, then the push bars 102 - 106 can be pushed further forward in the direction F, as by other bars 170 until the rear ends 172 of the push bar have been pushed forward of the guideways 154.
  • Fig. 16 shows a next step, wherein the upper housing 40 with contacts 50 installed therein, and with the push bars such as 106 still in place, is installed between the piston 180 and anvil 182 of a press 184 that can apply forces of up to a few tons.
  • the circuit board lies on a support 186 which supports locations on the circuit board immediately beyond opposite sides of the six rows of contacts.
  • a hard rubber plate 190 has been placed on the upper surface 124 of the connector housing 40 to assure that downward forces on the upper surface 124 are uniformly distributed thereon, the hard rubber plate 190 being softer than the more rigid material of the thermoplastic housing 40.
  • the press is then operated to move down the piston 180 to press fit the contact mount portions 64 into the circuit board holes.
  • the invention provides a method for the installation of large numbers of miniature contacts in interference fit with a circuit board according to claim 1, and a combination of a connector assembly and a circuit board according to claim 7, constructed to facilitate such installation.
  • the method includes using each contact mount portion with a largely upwardly-facing shoulder, and using an upper housing with a largely downwardly-facing surface region spaced above the shoulders.
  • a push bar is installed between the contact shoulders and housing surface region so downward force on the top of the housing can be transmitted through the push bar to the shoulder of the mount portion to apply a large downward force to the mount portion that press fits it into a circuit board hole.
  • the push bars can be installed in a direction parallel to the rows of contacts, and preferably with each push bar lying against shoulders of contacts lying in two adjacent rows.
  • the lower tips of the contacts can be pushed into accurate alignment with circuit board holes, by an aligner that presses against a contact location closer to the lower tip of the contact than to the mount portion.
  • Each aligner can be in the form of a bar having a greater width than thickness, and which is installed with its width dimension vertical, and which is then turned so its width dimension is horizontal to deflect a pair of contact locations apart.

Abstract

Procédé permettant d'effectuer l'ajustage serré de rangées de contacts miniatures (50A, 50B, etc.) dans une plaquette (34) de circuits imprimés, puis d'introduire les parties terminales inférieures des contacts dans des trous prévus dans un boîtier de connecteur inférieur, ce procédé facilitant le montage. Lorsque les parties terminales supérieures (60) des contacts sont installées dans un boîtier supérieur (40), on introduit des barres d'entraînement (102-106) entre la surface inférieure (84) du boîtier supérieur et des parties (64) de montage des contacts qui doivent être ajustées serrées dans des trous de la plaquette de circuits imprimés. Lorsqu'on appuie fortement sur la surface supérieure (124) du boîtier, les forces sont transmises par les barres d'entraînement (106 par exemple) sur le dessus des parties de montage qui pénètrent alors dans les trous de la plaquette. Les barres d'entraînement sont alors éliminées. Avant d'introduire les bouts inférieurs (100) du contact dans les trous (66) de la plaquette, on installe des barres d'alignement (120) entre les extrémités inférieures des paires de contacts, de manière à pousser légèrement sur le côté les extrémités inférieures du contact de sorte que leurs bouts inférieurs (100) soient alignés par rapport aux trous (66) de la plaquette de circuits imprimés.
