Definitions

  • the present invention relates to electrical connecting means. More particularly, it pertains to printed circuit to the manner in which the control components of the machine are to be operated.
  • the contact-carrying boards one of which is usually fixed relative to the machine while the other is moved into and out of cooperating relationship therewith, are positioned in and relatively manipulated by a suitable mechanism as shown, for example, in Patent No. 2,927,295.
  • the rows and columns of contact elements on the fixed board typically constitute the terminals of electrical conductors leading from the sensing elements and the instrumentalities'to be controlled in the machine, and on the movable board provide rearrangeable interconnecting plugs or jacks through which the particular circuit connections on the first board may be made.
  • several hundred contact elements are located on each board in a minimum area with a minimum space between rows and columns.
  • the movable board readily rearrangeable, but when the rearrangement would be extensive, it is preferably replaced by another movable board already pre-programmed in the new arrangement.
  • Bus bars proved to be bulky, tended to make poor contact unless soldered or screwed into place, and often required redesigning the existing patchcord systems.
  • Wirewrap and soldered wire jumpers were diflicult and costly to apply, especially in such confined spaces, and often gave rise to shorting due to slack wire.
  • Even a coiled conductive spring has been proposed as a jumper, which appears to be a bulky, probably expensive item, that would tend to make a poor contact.
  • Another object is to provide a versatile jumper device that can be readily applied and used in the confined spaces common to the plugboards employed in patchcord and other systems to jumper two or more plug contacts whether in adjacent holes or not.
  • Still another object is to provide such a jumper which can be easily mass produced and yet to adapt readily to different design requirements for different plugboard jumper situations.
  • Yet another object is to provide an assembly where such a jumper maintains gas-tight, mechanically strong connections having a substantially constant low resistance in spite of varying environmental conditions, and further without having a significant current leakage.
  • An advantage of this invention is the creation of a jumper with integral terminating means made solely by printed circuit techniques without any special termination adapters screwed, soldered, or otherwise aflixed to the jumper.
  • Another advantage lies in the creation of such a permanent terminating means which is dependable and electrically superior.
  • Still another advantage is the creation of a printed circuit procedure whereby the baseboard is preformed and the printed circuit applied thereafter instead of forming the printed circuit and then drilling out or otherwise modifying the baseboard.
  • This reversed procedure has the advantage of not subjecting the thin circuitry to the shocks of processing the baseboard and further permits the formation of tabs or other similar circuit overhangs previously though impossible.
  • FIGURE 1 is a plan view of a portion of a plugboard illusrating several preferred embodiments of our printed circuit jumper invention with several of the dimensions of this and the following figures exaggerated for emphasis as will become evident from the subsequent discussion, and with the lower portion of an electrical contact (plug) shown, in horizontal section, inserted in the upper left hand plug hole (see line 11 in FIGURE 3).
  • FIGURE 1A is a simplified embodiment of our invention
  • FIGURE 2 is an exploded elevational view taken line 2-2 in FIGURE 1 of the plug and, in cross sect on of a portion of the plug board and of the jumper device;
  • FIGURE 3 is an elevational view similar to FIGURE 2, except with the plug inserted, taken along line 33 in FIGURE 1;
  • FIGURE 4 is a horizontal section of the plug taken along line 4-4 in FIGURE 3.
  • the lamina jumper device 10 having tab terminating means 12, is illustrated as applied to a preformed baseboard 14, here shown as a plngboard.
  • the electrical contact, or plug, 16 upon insertion into one of the plugholes 18 (which is jumpered by one of the devices engages the tab contact 12, forms it over against the wall of the hole 18 (see FIGURE 2), and establishes a good electrical wipe-contact with the jumper 10 through the tab 12.
  • this invention comprises a thin metal electrical jumper 10a fixed to a baseboard 14a and extending between two plugholes 18a having at least one tab portion 12 extending over each of said holes 18a; so that, when a snugly fitting plug 16 is inserted into plughole 18a at either end of the jumper 1011, an effective jumper circuit is thereby completed. See FIGURE 1A.
  • This novel jumper 10 takes advantage of the simplicity and cost savings inherent in normal printed circuit procedures, and additionally makes the innovation of applying a printed circuit over a preformed baseboard in such a manner that portions of the printed circuit extend unsupported out over cut-away portions of the baseboard (for example, over plugholes 18 in the plugboard 14) and use such an extension as a terminating means 12.
  • FIGURE 1 may advantageously be prepared by applying a thin copper lamina to the preformed plugboard 14b by any of a number of well known adhesives, for example epoxy resin.
  • a protective coating of tin solder, or other similarly effective substance, may be then placed over the copper to prevent corrosion of the copper and also to enhance the electrical contact properties of the device.
  • a pattern of etch-resist material is placed over the exposed areas of the copper lamina by a standard screening or photographic method and then etched to form the desired jumper devices 10, complete with overhanging tabs 12.
  • This plug 16 has a lead-in taper so that upon insertion into holes 18b the tabs 12 are formed over and the plug 16 is compressed to partially close the slot 22 and thereby build up an outward radially directed pressure against the walls of hole 18b and therefore againstthe tabs 12 wedged therebetween.
  • the plug 16 as illustrated in FIGURES 2 to 4, is already disclosed in an application of my co-worker, John G. Hatfield, Ser. No. 298,002, filed July 25, 1963, which was copending with the parent application of this case and which is now Patent No. 3,288,915, issued Nov. 29, 1966, and is presently being commercially used in the patchcord assemblies disclosed in Patents Nos. 2,882,508 and 2,927,295. This serves to illustrate how the present invention can be used with existing patchcord systems and not require any modification of the various elements thereof.
  • plug 16 illustrated as having a substantially circularly cylindrical body portion 20 with a longitudinal slot 22, is that when such a plug is inserted into its plughole 18 it exerts not only a longitudinal pull on tabs 12 but also a circumferential shear if the tabs should be oriented close to the slot 22. Clearly this circumferential shear diminishes the further the tab is placed away from this slot 22. Therefore, jumper 10b takes advantage of another design feature of the plug 16, illustrated in FIGURES 2 to 4.
  • the body portion 20 is flattened into an orienting surface 24 on either side adjacent to the slot 22 in order to provide an orientation of the plug as it is inserted into holes 18b, which in turn have a corresponding flattened shelf 26 in the lower half of each of the holes 18b, thereby giving the hole outline at that point a D-shape.
  • this orienting means, 24 and 26 it is possible always to have tabs 12 placed sufficiently far away from the slot 22 to avoid most of the detrimental shear action encountered upon the insertion of the plug 16 into the hole 18b. It has been found advantageous to employ two tabs 12 as a safety feature in case one should prove to be faulty (as may happen in mass production).
  • this pair of tabs 12 are spaced from each other and from shelf 26 thereby minimizing the shear on the tabs. If the tabs 12 were located closely adjacent to each other, then the longitudinal pull therealong would be concentrated at one point on the jumper 10, thereby requiring a larger jumper 10 at that point in order to withstand this pull, and there might not be sufficient clearance between the plugholes to allow for the wider jumper surface required to give increased adherence to the plugboard 18 at that point.
  • the jumper is made from what is called in the trade two ounce copper, which has a thickness of approximately 0.0028 of an inch.
  • One standard plugboard 1412 has plugholes 18b spaced 2. quarter of an inch apart with the holes themselves having approximately 0.15 inch diameters.
  • Each tab 12 is approximately 0.04 by 0.03 inch, and though the jumper is close to a fifth of an inch 'wide across its center, yet that portion connecting the two tabs 12 at a plughole 18b is only 0.04 inch wide.
  • extension 28 of the jumper 10b actually overhangs the hole 18b and serves only as an outside visual orien tation to locate the shelf 26 and is not intended to give any added structural support to the jumper 10b.
  • the patchcord system in which this particular jumper with the above dimensions was to be used had a normal working voltage of 50 volts or less. However, these jumpers are spaced by at least 0.04 inch from each other between adjacent holes and have been actually tested to have a minimum voltage breakdown of 1.20 kilowatts. Thousands of test readings showed this jumper device to have a plug to plug average resistance reading of less than a milliohm, and even under the most severe testing conditions this resistance was rarely doubled. Furthermore, it was found that one tab of this installation was completely sufiicient both electrically and mechanically, and a second tab was needed only as an added safety feature to increase on a mass production basis an already surprisingly high reliability. Three or more tabs could have been used, but in the illustrated embodiment having the above dimensions additional tabs were found unnecessary and bulky and therefore impractical.
  • FIGURE 1 illustrate various modifications to jumper b.
  • jumper 10b is shaped to extend between two opposingly oriented plugholes 18b
  • jumper 100 is a mirror image of 10b in order to jumper two reversed opposingly oriented plugholes 18 and still leave the minimum clearance from the first.
  • Jumpers 10d and 10e show another suggested shape.
  • Jumper 10] illustrates how two or more remotely located plugholes might be advantageously jumpered by the present invention.
  • an electrical assembly comprising a firm insulation board having a substantially cylindrical hole therein; an electrical contact mounted in said hole and having a body portion formed of a conductive spring metal and having a longitudinal slot therein to permit compression thereof, a thin fragile lamina of conductive metal having a thickness typical for printed circuitry, said lamina being fixed to said insulation board and having tab portions extending down into said hole in good electrical wipe-contact with said body portion of said contact and wedged between said body portion and the walls of said hole, said body portion being naturally slightly larger than the space left within said hole by said tab portions and being shaped to exert a residual contact pressure against said tab portions, means for orienting said contact within said hole, said tab portions being disposed in said hole in positions substantially removed circumferentially from said longitudinal slot.
  • a plugboard assembly comprising a plugboard having a plurality of holes therein; electrical contacts mountable in said plugboard holes, each having a resilient cylindrical body portion with a longitudinal slot therein, thereby being adapted to exert a residual pressure against the walls of said plugboard hole; means for rotatively orienting the insertion of said contacts within said plugboard holes; a thin metallic jumper device fixed to said plugboard, extending between two adjacent plugboard holes and spaced from any conductive elements, other than electrical contacts mounted in the two adjacent holes, sufficiently to avoid voltage breakdown therebetween, and spaced from any contacts mounted in said two adjacent holes sufiiciently to avoid mechanically dislodging said device from said plugboard except for two tabs which extend radially in over part of each of said two adjacent holes which tabs are oriented such that insertion of said contact into one of said holes will engage the tabs respective at substantially from either side of said longitudinal slot thereby wedging said tabs in good electrical wipe-contact between said cylindrical portion of said contact and the walls of said plugholes.
  • a combination as described in claim 2 wherein said jumper device is generally about 0.003 of an inch thick, is spaced from any conductive elements other than electrical contacts mounted in the two adjacent holes by at least 0.040 inch and is spaced from the contacts mounted in said adjacent holes by about 0.005 to 0.010 inch.
