Definitions

  • Connectors of the above type have numerous advantages in addition to providing a superior electrical connection with a disconnect function.
  • One of the principal additional advantages is that manufacturing and .use tolerance deviation, with respect to the interm ating of parts, is broadened such that production and wear differences in the positions and sizes of relative parts are inherently accommodated by the characteristics of connector design.
  • the pin member to be inserted in a given socket member is slightly smaller or larger than optimum due to production tolerance deviation, a good connection may nevertheless be made if the relaxed diameter of the spring part is made such that the maximum tolerance deviation cannot cause the parts .to fail l
  • the same is true with respect to placement of the cooperating connector parts, especially in multiple mounting wherein no one connector half can be exactly :placed with respect to complementing halves.
  • the present invention constitutes an improvement over the above mentioned prioriart, especially with regard to -multiple mounting and to miniatureconnectors.
  • the smaller the ,particular component or .part being manufactured the more diflicult tolerance control becomes.
  • a pin and socket intermating diameter is nominally two hundred mils
  • a'control to fivepercent accuracy permits a tolerance deviation of ten mils, which is relatively easy to maintain with. existing manufacturing equipment.
  • the same is true with .respect to techniques .utilized in molding plastic blocks for housing connector parts wherein the center-to-center spacing can'be readily controlled to a tolerance deviation of five percent.
  • the developing use of smaller and smaller electronic components asfor so-called microminiature devices has, however, so reducednominalconnector dimensions and center-to-center spacing of parts as to aggravateproduction problems. Additionally, with. respect to the smaller sizes,

  • the foregoing objects are attained in the present invention through the use of a novel pin and socket construction wherein the forming of either the male or female members of the invention is accomplished in a manner wherein desired spring resiliency is built into such member as it is formed into its final configuration.
  • the invention contemplates a construction permitting the same basic material structure formed ior one range of conductor sizes to be utilized directly in forming connectors for other ranges of conductor sizes.
  • the angular arrangement and working face disposition of the spring members of the connector of the invention are made such that insertion and withdrawal axial forces are not excessive, yet at the same time substantial radial spring forces are developed to maintain the necessary inter-face between connector parts.
  • FIG- URE 1 shows the edge end of an assembly for interconnecting individual groups of electronic components in 'a manner whereby packaging density and replacement is tacil-itated.
  • Each group of components may be considered as mounted in one module 10, of which numbers of such modules are adapted to be plugged into in an appropriate position in an insulating board member 12.
  • Each module 10 includes a number of projecting conductive pin members 14 extending from within the module connected to components therein and projecting from beneath the module to cooperate with conductive socket receptacles 16 aligned in the pattern of the pin members to intermate therewithin.
  • the projecting pin members 14 and sockets 16 are arranged so that the placement of the center row of pins and sockets provides keying for proper module orientation. In this manner, modules are mechanically and electrically connected to board 12.
  • interconnection between a given module such as 18b and external circuits is accomplished by conductive paths provided between posts 18b and edge mounted posts 20 and sockets 21, to which a suitable connector 22, having pin members similar to pin members 14 is connected to provide paths to appropriate external conductors 23.
  • the scheme shown for accomplishing the extension of conductive paths between posts is one which is particularly adapted to fine wire and the smaller sizes of insulated conductors used with miniaturized electronic components.
  • This scheme is shown generally in FIGURES 3 and 5, wherein Formvar coated conductive wire is terminated by the use of a tapered post and sleeve connection of the type described in US. Patent No. 3,071,750 to J. C. Heselwood, granted January 1, 196 3, or the type shown and described in US. patent application No. 201,983, in the name of the inventor and Carl F. Vieser, filed June 12, 1962, now Patent No. 3,249,908.
  • This type of connection has been found to have substantial utility wherein the wire characteristics are such as to make other pointto-point wiring schemes unsuitable, e.g., Wire-Wrap or soldering.
  • FIGURES 3 and 4 it will be seen that to interconnect a given module such as 10, the module is positioned over the insulating board 12, at an appropriate position which may be marked by some symbol or color corresponding with a mark on the particular module. With the module pins 14 aligned in accordance with sockets 16, the module is then forced down onto the board with the pins being inserted in their respective sockets. It is this type of use that raises the problems with prior art devices above outlined. For, as will be recognized, both dimensional and spacing deviations, as well as insertion-withdrawal forces are cumulative with respect to the pins of each module.
  • FIGURE 4 an enlarged sectional view of board 12 shows a pin 14 positioned above a corresponding socket 30.
  • Sockets 30 manufactured of soft copper or brass have been found to operate satisfactorily with respect to such forming. It is contemplated that sleeve 34 may be solid if of a soft metal construction or split, if relatively hard metal is used.
  • a post member 35 Opposite to flange 32, is a post member 35 ooaxially disposed within sleeve 34 and having a straight section 36 ended by a tapered section 37, having a number of circular serrations 38 thereon in accordance with the teachings of the above mentioned patent or application.
  • Extending through socket 30 is a bore 40, which has at the opening adjacent flange 32, a double step portion 42 defining a sleeve 44, which may be folded over, as better indicated in FIGURE 4a.
  • a spring member 46 Inserted within bore 40 and extending along a substantial portion of its length, is a spring member 46 representing one embodiment of the invention.
  • the upper end of spring member 46 includes a radial flange 48, which fits against the lower portion of step 42 and is captivated by sleeve 44 folded down thereagainst.
  • the socket 30 may thus be seen to provide an extremely simple means for locking itself into board 12 and also a simple means for locking the associated spring member therewithin. It is to be noted that this socket construction comprises only two loose pieces, which favorably compares by a considerable margin, with other known devices capable of performing a similar function.
  • the relaxed state of spring 46 defines a free inner cross-sectional area along its center region, which is considerably less than the maximum cross-sectional area of pin 14.
  • the inner diameter of the entry portions of spring 46 is larger than the diameter of pin 14.
  • FIGURE 5 shows module 10 inserted on board 12,. with a pin 14 fully inserted within a socket 30'.
  • the free end 47 of spring 46 is moved downwardly 67, and 68.
  • connection from pin 14 to an auxiliary path such as to an adjacent module or to an external circuit is made through the tapered post 36 and a tapered sleeve in the manner more fully described in the above mentioned Heselwoo-d patent or in the application to Fuller and Vieser.
  • This is shown generally in FIGURES 3 and 5 with a sleeve 50 having an internal taper wedged down over post 36 to force the post serrations38 to terminate insulated wire 52 by biting through the insulation thereof into the center copper conductor. From'F IGURES 1 and 2, it should be apparent that the pin and socket connector of the invention, in conjunction with some means such as the tapered post and sleeve shown, can be employed to interconnect large numbers of distinct electrical paths.
  • module boards such as that shown, have been successfully arranged to provide a reliable interconnection of thousands of paths with post and socket diameters on the order of twenty mils and with center-to-center spacing between adjacent pin members on the order of fifty mils. This has been accomplished with an economy of parts and of assembly labor not heretofore possible.
  • FIGURE .6 an enlarged perspective of an embodiment of the invention including the spring construction above described is shown in detail.
  • the spring 60 which maybe considered as identical to spring 46 above described, is
  • End 62 represents the free end of the spring adapted for axial movement as above described and end 64- includes a radial extension 70, which serves the --flangefunction for holding the spring within the socket assembly.
  • the individual spring arms 66, 67 and 68 include a spiral configuration tapering inwardly toward the center longitudinal axis of spring 60 and at the same time twisting along their length to join tubular portions 62 and 64 in planes approaching the planar disposition of the metal at the point of juncture.
  • length of arms'66, 67 and 68 is made relatively long as compared with the inner diameter of the spring. Be cause of this, the inner surface of the center of the springs offers to a pin inserted therein, a possible contact area greater than devices of the prior art.
  • FIGUR'E7 depictsan end-onview of the spring 60
  • spring'60 could vary quite substantially from a size j-ust larger than the' hole76' that appearsin FIGURE 7, to a size approaching aperture74 indiameter.
  • FIGURE-'8 may be formed by .a standard blanking operation wherein dies are forced against the. sheet material toremove portions as indicated.
  • the sheet-stock material was 4 mils in thickness T, 148 mils in width W and 100 mil-sin length L.
  • the slots .84 of removed material were 93 mils in length and 15 mils in width.
  • the sheet stock material is then formed as shown' in FIGURE 9, by standard stamping techniques to include a'bow of mils, BL was mils, and F was'12 mils.
  • the configuration shown in FIGURE 9 is then formed in the cylindrical shape shown in FIGURE 10 to have an entry diameter'EDlarger than the maximum diameter of the particular pin size to be used with the device.
  • the relaxed inner diameter ID is made substantially less than ,such pindiameter.
  • dimension ED was'28.mils and dimension ID was approximately 12 to 14 mils to accommodate a range of pin sizes from 17 to 25 mils in diameter.
  • the first controlling factor is .pin diameter or the range of pin diameters to be employed. Given this and the fact that at least three spring arms are preferred, a'desired spring force is determined with,respect to the step of FIGURE 8, by the three variables of spring arm length, width and thickness.
  • the otherfactors may .inga pin diameter of 17 to 19 mils.
  • the forming of spring socket as shown in FIGURE 10 is accomplished by rolling the structure shown in FIGURE 9 to closure about spaced cylindrical mandrels forced against the upper surfaces of the members 81 and 82 of sheet 80.
  • the individual arms of the spring assume the configuration shown with the features above described without requiring a subsequent step of twisting the tubular end members 81 and 82.
  • the sheet 80 formed as shown in FIGURE 8 can be first rolled and then clinched inwardly .to define the bow of the same relative dimensions B and BL. This too is accomplished without twisting the tubular members 81 and 82, relative to each other.
  • the avoidance of twisting permits the spring to be mounted with one end relatively free for axial and rotary movement as is required to achieve the characteristics above described.
  • the advantage of the spiral disposition of the spring arms in providing an increased contact area is achieved.
  • FIGURES 11, 12 and 13 show an embodiment of the invention for such use.
  • 100 represents a sheet stock material which has been suitably blanked in the manner above described to define slots 102 and 104 joining end members 106 and 110, and a central member 108. Between each of the slots 102 and 104 a portion of metal, as above described, is left to define separate sets of spring arms 112 and 114.
  • FIGURE 11 The material blanked as shown in FIGURE 11 is then bowed as shown in FIGURE 12, with each of the separate spring members 112 and 114 formed inwardly in the manner above described.
  • a turned up flange 116 is provided to lock the spring member against relative movement in a suitable socket member, which is similar to the above described socket 30.
  • material 100 is then rolled as shown in FIGURE 13, to form a spring member having two sets of spring arms, each of which includes the desirable features above described. It is to be noted that the twists of the spring arms 112 and 114 are oppositely oriented. This feature has been found to provide a still better mechanical holding of a pin member within the spring due to inward forces having vectors in opposite directions.
  • the socket shown in FIGURE 13 may be utilized to interconnect separate pin members inserted from either end thereof. In such event it may be convenient to form a holding flange similar to 116, by folding member 108 in a closed U- shaped configuration. In such use ends 106 and 110 would be left free to expand outwardly.
  • the spring formed in accordance with FIGURES 11, 12 and 13 could, of course, have slots of similar sense of rotation if such is desired and could be formed by a final step of clinching rather than the step shown in FIGURE 12.
  • FIG- URES 14, 15 and 16 A further aspect of the invention is shown in FIG- URES 14, 15 and 16, wherein a section of sheet metal material 120, is shown blanked to define slots 121 and spring arms 122, 124 and 126.
  • the spring arms are interconnected between end portions 128 and 130.
  • the sheet is further blanked proximate end 130 to define projections 132 extending outwardly therefrom.
  • the sheet material 120 after blanking, is further formed with the arms being bowed as shown in FIGURE 15 andthereafter rolled into the configuration shown in FIG- URE 16.
  • the flanges 132 serve as anchoring portions similar to flange 48, as above described with respect to FIGURES 4 and 4a.
  • the end tubular portions 128 and 130 are formed in a square configuration, which feature could, of course, be employed with any of the preceding spring embodiments. By having square end portions, the center-to center spacing between springs may be reduced.
  • FIGURES 8 and 14 A comparison of FIGURES 8 and 14 will reveal that with sheet material blanked in continuous lengths, any number of ranges of connector sizes may be accommodated by merely selecting the number of arms necessary and the particular tubular configuration desired. Thus, for a given pin size, four legs may be selected to provide a suitable spring diameter. For a larger pin, five or six legs may be used with an appropirate roll of tubular end portions. This operates to provide wide utility of use for the stock material in its basic form.
  • FIGURES 17, 18 and 19 show an alternative embodiment wherein the novel spring construction of the invention is formed in a pin configuration rather than in a socket configuration.
  • the method of manufacture is substantially the same. Beginning with sheet stock material 140, blanking operations are carried out to pro vide slots 141, defining legs 142, 144 and 146 separated and interconnected to end portions 148 and 150.
  • the end of portion 150 is preferably blanked as shown with V notches defining ends 152 and the sheet material formed as shown in FIGURE 18 to include a bowed portion with ends 152 turned downwardly. Thereafter, the formed sheet material is then rolled around a cylindrical mandrel to form a pin member with spring arms bowed outwardly rather than inwardly.
  • the blanked configuration of end 150 including members 152 in conjunction with the folding as shown in FIGURE 18 and rolling as shown in FIG- URE 19, defines a pin member 162 tapered so as to avoid any possibility of the pin catching upon the edges of the aperture in which it is inserted.
  • the opposite end 148 is formed in a tubular configuration 154, which is convenient to receive one of the leads of an electronic component which may be crimped or soldered thereto in a suitable fashion.
  • the usual construction calls for the pin member 162 thus formed to be mounted in a phenolic or other insulating board upon which the particular electronic components are mounted with the bore 154 protruding through the board and attached to a component lead. Thereafter, the whole assembly is potted by molding insulating dielectric material therearound to form a module as shown in FIGURES 1 and 2. If desired, anchoring spurs or flanges may be included along 148 to better serve the pin member.
  • FIGURE 20 shows a module with a single pin 162 extending therefrom and aligned over an insulating board 164 having an aperture 166, in which is secured a socket member 168 in the same manner as socket 30',
  • Socket 168 includes a tapered post portion 169, which may be terminated as above described, and a central longitudinal bore 170.
  • the bore 170 is sized to be smaller than the maximum diameter of pin 162 and slightly larger than the minimum outer diameter of the pin.
  • pin and socket may be utilized separately or in smaller numbers to perform interconnecting functions between electrical signal paths.
  • the emphasis of the advantages of the invention has been stressed with respect to smaller conductors in smaller sizes, wherein the particular advantages of the invention are most useful. It is also contemplated, however, that the assembly of the invention can be utilized with larger sizes with an appreciable economy over existing connectors of the prior art.
  • point-to-point wiring has been shown to be a tapered post and sleeve construction in accordance with the above mentioned patent. It is also contemplated that other point-to-point wiring schemes may be accommodated by altering the construction of the sockets to include, rather than a tapered post, other configurations of terminals. For example, a solid Wire-Wrap post could be provided to accommodate either Wire-Wrap or to accommodate clipon type connections.
  • printed circuit paths on the insulating member could directly interconnect to different socket members by direct engagement with one of the flange members thereof.
  • An improved method for forming pin or socket spring members of the type having an axis of travel to provide engagement for electrical connection comprising the steps of blanking a flat sheet of relatively thin metal material to define a configuration including end portions having the length thereof extending in a direction transverse to the axis of travel with said end portions being spaced apart and joined by material blanked to define a plurality of slots and a plurality of arms, with a slot disposed between each arm of a width equal to or greater than the width of an arm and with the slots and arms being generally parallel to each other and diagonal to the axis of travel such that the perimeter of said configuration is generally rhomboidal, stamping the said arms into an arcuate configuration in a direction transverse to the axis of travel and rolling said blanked and stamped sheet material to a point of abutment of the edges of the end portions to define tubular portions of substantially the same diameter joined together by helically disposed arms.
