  • This invention relates to a programming system of the type utilized to selectively interconnect electrical circuit paths to control the function of electrical and/or electronic equipment.
  • One aspect of the present invention is to provide a programming system which has fewer parts and is simpler and cheaper to manufacture than prior art devices of an equivalent function. It is an object of the invention to accomplish this through a board structure which is smaller, lighter and stronger than the structures of the prior art.
  • the system of the invention includes a contact structure which has, as its object, the provision of connections which are'more reliable than the spring contact systems of the prior art, and have better electrical qualities than the fixed contact systems heretofore available.
  • a further aspect and object of the invention is to provide a novel programming pin which is simpler, cheaper and more reliable than spring-type pins heretofore available, and to provide a diode programming pin having a spring construction arranged to provide superior electrical contact characteristics.
  • a board comprised of two identical blocks, each carrying an array of flat strip contacts and each designed to intermate to lock sets of strip contacts within the assembly.
  • the contact strips of the board are rigid or fixed.
  • Shorting and diode pins are provided which are live or have spring characteristics; and, as an important aspect of the invention, the spring characteristics are divided into several axially-spaced spring sets relatively isolated from each other and yet joined together for use.
  • the invention features a board configuration which is slightly curved as initially manufactured and then forced into a planar shape to develop residual stresses holding the combination of boards together and the springs therein against transverse movements within the boards.

  • FIGURE 18 is a longitudinal section showing the construction of the diode terminal pin of the invention.
  • FIGURE 19 is an end-on view thereof.
  • the system includes a terminal board assembly 10 comprised of two apertured boards B1 and B2 of insulating material, four frame pieces comprised of two pairs of identical pieces F1 and F2, upper and lower contact strips C1 and C2 and a plurality of pins and terminals.
  • the pins and terminals include a shorting pin 12, a diode pin 14, a terminal post 16 adapted to be engaged by a receptacle (not shown), a soldering terminal post 18 and a receptacle terminal 20. It is to be understood that in a typical application, only several of these terminals will normally be employed. For example, for the size board shown, which is a 9 x 9 matrix, the system might include eighteen termipins 14.
  • nal posts such as 16, disposed inoutside rows, and ten shorting pins, such as 12, placed in positions throughout the array of apertures in the board to program the device in accordance with the desired function.
  • the system might include the board as shown with eighteen soldering posts 18, five shorting pins 12, and five diode
  • the general arrangement of the system is such that inputs are applied to the contact strips through terminal posts disposed along two sides of the periphery of the array of apertures in the board on one side thereof, with programming pins being inserted in the appropriate positions from the other side.
  • the upper part of assembly is the front face of the board and the lower part is the back or rear of the board.
  • FIGURE 1 shows the board from the back
  • FIGURE 2 shows the board with the rear faced upwardly.
  • the input and output rows of apertures are labeled numerically and alphabetically.
  • the front face of the board is reversed from that shown in FIGURE 1, such that the upper left-hand aperture would coordinate 1-A relative to the insertion of a programming pin.
  • insertion of a programming pin'12 in the aperture at 1-A will result in the completion of an electrical path from the input lead through the contact strips and the barrel portion of the programming pin to the output lead.
  • other completed paths may be selected by the insertion of pins in the various alphanumeric positions disposed in the array of apertures in the board.
  • the assembly 10 may be desirable to provide the assembly 10 with only one level of contact strips, each terminated to an input with an array of terminal receptacles disposed, as indicated in the drawings, such that the insertion of a pin 12 will establish a connection from the associated strip to an output lead via the pin through the receptacle.
  • the board assembly is comprised of but two board members B1 and B2 which, in accordance with the invention, are identical such that they may be manufactured from the same mold, or at least duplicated if machined or otherwise processed.
  • the interior configuration of each board can be seen from FIGURES 3 and 9 to include a body 1a which is preferably a onepiece integral structure of insulating and/ or dielectric material having a series of apertures lb disposed in matrix array transverse to the major plane of the body and eX- tending therethrough.
  • the board body On either side of the board body are provided a series of rectangular or square projections of various lengths.
  • the projections on the outer surface of the body are shown as 1c and Id, and are made to be of a relatively limited height for the purpose of engaging the frame members F1 and F2 in the manner indicated best in FIG- URE 3.
  • the inner projections 1d may be, in certain instances, left oif of the body since the frame members need engage only the outer projections in the embodiment herein shown.
  • providing projections Id throughout the upper face of the board is considered to be desirable.
  • the board body as shown, may be cut into smaller sizes with the 4 projections being utilized to accommodate similar frame members.
  • the existence of the projections aids in identifying the positions of the apertures for pin insertion. In this regard, it may be found desirable to color the surfaces of the projections of 1d, as by silk-screening or the like.
  • each board includes rows of continuous projections 1e with a series of integral further projections 11 on each row.
  • the spacing between the projections 11 is such as to accommodate contact strips which are extended across the board in grooves between projections la.
  • the projections 1e and 1 are dimensioned and positioned such that when one body containing its contact strips is rotated 90 relative to the other body member, the two body members may be forced together with the projections 1e and 1 thereof interdigitating to hold the contact strips in position.
  • the projections 1e hold the contact strips against movement in a direction transverse to the length of the strips
  • the projections 13 extend to hold the contact strips against movement in a direction transverse to the plane of the strips.
  • the panel P is not shown to contain the projections and apertures heretofore described with respect to board members B1 and B2, but such features may be considered as included. Considering P to be approximately four times the area the size of boards B1 and B2, two complete board assemblies may be made up by cutting the panel into four equal squares.
  • the panel P represents a molded piece which is molded in the Hat and then deformed during cooling to have a very slight bow in the manner indicated by the solid lines in FIGURE 4.
  • the bowing may be accomplished by supporting a freshly-molded panel horizontally along its edg s with the center unsupported and with a small weight placed on the top surface thereof. A stop disposed below the center will control the displacement to a desired value while the panel cools. With P bowed, as indicated in FIG- URE 4, and cooled to take a permanent set in this shape, the sections P1 and P2, cut out as indicated in FIGURES 5 and 6, will also have some degree of curvature. In an actual panel having a size approximately seven inches square, the bow at the center thereof was made to be approximately V of an inch.
  • the sections P1 and P2 are oriented relative to each other,.as indicated in FIGURES 5 and 6, to provide alignment for intermating as heretofore described, and then are positioned in the manner indicated in FIGURE 7 such that the faces of the sections have their concave surfaces outwardly and their convex surfaces inwardly.
  • the application of frame members, such as F1 and F2 heretofore described will result in the sections being forced into a flattened configuration as indicated in FIGURE 8. This serves to develop a residual stress in the panels tending to hold the centers thereof in engagement, and further tending to hold the outer. edges thereof better in engagement with the frame members.
  • the residual stress which is developed toward the centers of the boards also serves to contain the contact strips by holding the projections of the board against outward displacement. If the boards were molded .in the flat or left to some production tolerance which would permit a slight inward bow reverse to that shown, slight transverse spaces between the surfaces of the projections would result and the contact strips could float within the assembly. Similar effects, due to humidity, are also resisted through the foregoing construction of the board assembly of the invention. It is contemplated that this aspect of the invention may be employed in any lamina assembly of boards or panels, and particularly in any such assembly wherein loose-piece contact strips are contained between laminations.
  • the frames include a body 2 having an outer wall section 2a, and sidewall sections 2b and 20 which project from the wall section 2a to form a U-shaped channel.
  • the wall section 2b is made to be wider than the wall section 20 so as to cover over an extra row of apertures in the upper board member.
  • the strip configuration shown as 4 in FIGURE 9, represents the simplest embodiment contemplated, in that the body 4a includes substantially circular holes 4b spaced along the length in positions aligned with the apertures 1 of the upper and lower board members.
  • the holes 4b are made to be slightly smaller than the apertures 1b, and the strip 4 is of a width to fit rather exactly in the groove between projections 1e.
  • the length of the strip is tailored to leave the ends thereof out of engagement with the frame members if such are of metallic construction.
  • the strip shown as 5 in FIGURES l and 11, includes a body a which, in length and width, is substantially like that of 4.
  • the strip holes 5b are made oblong, with the dimension of maximum length lying along the longitudinal axis ,of the strip.
  • Holes 5b are radiused about each edge, as at 5c in FIGURE 11, and include sidewalls substantially parallel and spaced apart by dimension slightly less than the relaxed dimension of the programming pin utilized in the system.
  • FIGURES 12, 13 and 14 a further embodiment of the strip is shown, which is similar in plan to that of the embodiment of'FIGURES and 11, to include a body 6a and spaced, oblong holes 6b.
  • the holes 612 are radiused by'a forming of the metal to develop an eyelet structure, as shown in'FIGURE-13.
  • a tab 6d struck out as indicated to extend below the-plane of the'strip' is engaged by the projections 17 of the upper and lower board members to better hold the strips within the board member slots and thus further relieve tolerances.
  • the feature represented by the tabs prevents slight transverse movement of the strips during pin insertion and withdrawal throughout the area of the board members, and the feature may be utilized in lieu of the bowing of the boards heretofore described or in COIIJUHCIIOH therewith.
  • the strip 4 is preferred in uses wherein the programming pin employed does not have a generally cylindrical terminal configuration.
  • the embodiment, shown as 5, is preferred where it is desirable to have relatively thick, heavy metal stock which must be coined to provide the radiused edge 5c and cannot be formed as in the embodiment of FIGURES 12-14.
  • the embodiment 6 is preferred wherein the metal stock is relatively thin and may be easily formed.
  • the shorting pin 20 is comprised of a plastic handle 22 and a contact barrel 24 having spring characteristics.
  • the handle 22 includes a bore 22a which is of a cross-sectional dimension less than the relaxed crosssectional dimension of the end of the barrel 24 and of a depth to provide suflicient bearing area to hold 24.
  • a further bore is provided which is of a diameter approxim'ately equal to the relaxed diameter of 24.
  • the programming pin barrel 24 is rolled from the stamping shown in FIGURE 17 to form a live pin structure with three, relatively-isolated, radial spring systems indicated in FIGURE 15 as operating in planes I, II, III.
  • the spring acting in plane I is, as described, adapted to lock the pin barrel to the pin handle.
  • the spring acting in the plane II is adapted to operate to effect contact with the upper contact strip C1, as shown in FIGURE 3, through an engagement with the holes of the contact strip.
  • the end of the barrel 24 is a separate spring system operating radially in the plane III to fit within and be compressed by the holes in the lower contact strips C2.
  • the various spring systems in the planes I, II :and III are isolated by reason of the disposition of the seam, shown as 24a, which is made to extend along and around the length of the member 24 to position the material edges so as to close as the pin is compressed normally relative to any two adjacent zones.
  • This means that the outer end of the pin 24 may be compressed without also compressing portions of the pin in plane II.
  • portion of pin in plane II may be compressed without compressing portions in planes I and III. Because of this, the pin of the invention may be utilized with the fixed contact represented by contact strips C1 and C2.

  • the diameter of the bore 32a in the region of portion 36 is made slightly smaller than the diameter of the contact member so as to develop a spring reserve directed outwardly to hold the member in the handle against axial pull-out.
  • Member 34 includes a forward resilient portion 34c comprised of spring finger members which extend in the general direction of the axis of the diode pin assembly, and are suitably relieved relative to 42 to define a radial spring action.
