Definitions

  • This invention relates to an electrical connector and particularly to an improved electrical contact member for lreceiving and making contact with a square or rectangular pin connector.
  • the Contact member includes a contact socket formed from relatively malleable sheet metal stock and a bowed metal spring which is held within the socket.
  • the spring and socket cooperate to assure that a positive electrical connection is made between the socket and the -pin despite repeated insertions of the pin into the socket.
  • the socket is provided also with novel means for orienting the pin as it is inserted so as to assure proper mating of the pin in the socket.
  • an object of the invention is to provide an improved electrical connector.
  • Another object is to provide an electrical Contact element with a novel spring and socket construction having a long useful life.
  • a further object is to provide an electrical connector having improved means for orienting the contact pin within the connector.
  • FIGURE l is a top plan view of a contact member according to the invention.
  • FIGURE 2 is a side view of FIGURE 1;
  • FIGURE 3 is an enlarged sectional view taken along line 3-3 of FIGURE 2;
  • FIGURE 4 shows a ladder of spring elements formed from a sheet metal strip
  • FIGURE 5 is a view similar to FIGURE 2 except that a disconnect pin has been inserted into the contact member;
  • FIGURE 6 is a sectional view taken along line 6 6 of FIGURE 5;
  • FIGURE 7 is a sectional view similar to that of FIG- URE 6, showing a modification of the invention.
  • FIGURE 8 is a partially broken away view similar to that of FIGURE 5, showing a modification of the invention
  • FIGURES 9, 10, l1, 12 and 13 illustrate a modified form of the invention
  • FIGURE 14 is a sectional view of another modification of the invention taken along line 14%*14 of FIG- URE 15;
  • FIGURE 15 is a sectional View taken along line 15-15 of FIGURE 14.
  • FIGURE 16 illustrates a further modification -of the invention.
  • the invention comprises a contact member 10 having an elongated socket 12 with base 14, side walls 16, and a top formed from bent over tabs 18 located at each end of the .side walls 16.
  • a suitable wire Contact ferrule 20 is located at one end of socket 12.
  • the socket 12 and feriule 20 are formed from relatively malleable metal of high conductivity.
  • the socket base 14 includes stepped portions 22 at the lower ends of each side wall 16 and a disconnect groove 24 between the stepped portions 22.
  • the disconnect groove 24 runs the length of the .socket 12 and is defined by side walls 26 and a bottom wall 28.
  • a contact spring 30 is formed from a strip 32 of relatively resilient spring metal as illustrated in FIGURE 4. Portions 34 are punched from the strip 32 leaving a ladder-like strip formed of a number of contact springs 3) joined together at their ends so that the length of the contacts 30 forms the ladder rungs. The cut-out strip 32 is then fed between curved rollers so that the springs in the strip are bowed downwardly at the center thereof. The individual spring elements are then severed from the stri-p 32 and inserted in a socket 12, following which the upstanding tabs 18 are bent over as illustrated in FIG- URE l to form the top of the socket and hold the spring 30 within the socket.
  • the spring is confined between the socket side walls 16 with the center of the spring having a width almost equal to the interior width of the socket. To either side of the center of the spring the width thereof decreases so that the width of the spring adjacent the ends of the socket is substantially less than the width of the spring at the center of the socket.
  • the ends of the spring 30 are provided with lateral ears 36 which project to either side of the socket outside of the side walls 16 and limit axial shifting of the spring in the socket. Shoulders 38 located adjacent the ears 36 have a sliding fit within the socket between the side walls 16 and serve to position the spring 30 between the side walls.
  • the downwardly bowed spring 30 is normally confined in the socket 12 with the ends thereof slidably abutting the outer edges of the bent over tabs 1S and with the center portions thereof resting on the stepped portions 22 of the socket.
  • the spring 30 is not physically attached to the socket 12 but is movably confined in position within the socket by the ears 36 and by the spring tension due to its curved shape. This is important since the spring is free to move relative to the socket 12 so that the elastic limits of the spring 3f) are not exceeded as the pin is inserted in the socket.
  • a square disconnect pin 40 may 4be inserted into the socket 12 of the contact member 10 by pushing the beveled end thereof into the exposed-end of the disconnect groove 24.
  • the groove 24 has a width slightly greater than the width of the pin 40 and guides the pin as it is pushed into the socket. At the ends of the socket the distance between the bottom 28 and the spring 30 is greater than the pin height. This distance decreases toward the center of the socket so that the pin is easily placed in the end of the socket and inserted by pushing it along groove 24.
  • the spring and groove 24 assure that the pin is properly oriented relative to the socket so that the desired connection therebetween is achieved. Since it is contemplated that the pin may be very small with a side dimension of approximately 0.025 inch, this automatic alignment of the pin relative to the socket is very important because of the near impossibility of checking the orientation of the pin relative to the socket.
  • the spring 30 holds the contact pin 40 against the bottom 2S of the disconnect groove 24 as the pin is inserted into the socket and guarantees a positive wiping action between the contact surface of the pin 40 and the ybase of the groove. This wiping of the contact surfaces assures that oxides or impurities on either of the surfaces are broken up and that a desirable metal-to-metal contact is made between the surfaces.
  • the spring force exerted at the contact surface is greater than in conventional connectors of the type disclosed herein because the spring width is greater than the width of the square contact pin. This spring force guarantees that a proper electrical contact is maintained between thepin and the socket.
  • FIGURE 7 shows a modification of the invention wherein an upwardly extending contact ridge 42 is formed along the length of the bottom of the disconnect groove.
  • the height of the contact ridge 42 above the bottom of the groove Iis less than the height or the groove side walls i 26 so that the contact pin 40 is accurately held within the socket between the walls 26 and the contact ridge 42.
  • the ridge may extend the length of the socket or a number of ridges may be formed on the bottom of the disconnect groove.
  • the spring 30 holds the pin 40 against the top of the contact ridge 42. As illustrated in FIGURE 7, the stressed area of the spring is greater than the contact area of the socket so that a greater contact pressure etween the pin and socket is achieved.
  • FIGURE 8 Another modification of the invention is .illustrated in FIGURE 8 which is similar to FIGURE 5 with the exception that the bottom of the disconnect groove is provided with a recessed portion 44.
  • the recessed portion extends between the groove side walls and isolates the two bottom contact areas 46 with the result that a redundant contact is formed between the pin and the bottom Contact areas.
  • FIG- URES 14 and l5 utilizes a socket similar to that shown in FIGURES l and 2 with the exception that the bottom of the disconnect groove is provided with three upwardly projecting contact points 48.
  • the spring holds the pin in intimate contact with the three contact points 48 so as to provide the desired electrical connection therebetween.
  • the contact points 48 may be staggered within the disconnect groove so that the contact portions of the points define a plane which in cooperation with the dis-connect groove side walls properly orients the pin within the socket and provides the maximum redundancy of contact points. In very low voltage circuits where high -reliability is essential (such as in electronic -computers or missile control circuits) this configuration best assures multiple Contact with warped or bent pins 40. While the drawings illustrate a contact member with three contact points formed in the disconnect groove, it is clear that a different number of such contact points may be formed in the groove.
  • FIGURES 9-13 illustrate a modification of the invention in which the spring member 50 is of cruciform shape with lateral ears 52 at the center thereof.
  • the ears 52 are positioned within grooves 56 in the side walls 58 of the socket.
  • the ends of the spring 50 extend outwardly past the bent over top tabs 60 and slidingly abut the outward ends thereof.
  • Springs 50 are formed from a strip 62 of i relatively resilient spring metal by removing the areas indicated at 64 so as to form a chain of springs 50 connected by the lateral ears. The formed cha-in is then rolled so as to bend the spring 50 as desired.
  • the lateral ears 52 of the spring 50 limit axial shifting of the spring ⁇ within the socket.
  • the spring 50 is normally positioned in the socket with the center portion thereof resting on the stepped portions 66 of the socket and with the ends thereof biased against the top tabs 60 by the resiliency of the spring.
  • the contact pin 68 is inserted in the disconnect groove 70, the spring 50 is forced upwardly by the pin and holds the pin in the groove so as to assure a desirable electrical connection between the contact surface of the pin and the bottom of the disconnect groove.
  • the cruciform shaped spring may be used with any of the socket constructions previously described.
  • the spring 50 is widest at its center where the ears project outwardly of the socket.
  • the width of the spring tapers inwardly to either side of the center thereof so that the spring is uniformly ⁇ and elastically deformed when the pin is fully inserted in the socket.
  • this feature results in extended spring life so as to assure that proper connection ⁇ is made between the socket and the pin despite repeated insertions of the pin in the socket.
  • Spring 50 is also wider than pin 68 and accordingly exerts the desired high spring force at the contact interface.
  • FIGURE 16 illustrates a further modification of the invention wherein the ibottom of the disconnect lgroove is curved upwardly to provide a raised contact surface for engagement with pin 82.
  • The'l ⁇ he spring 84 holds pin 82 against surface 80 to assure a positive electrical connection despite relative movement of the pin and socket.
  • the contacts disclosed herein utilize a bi-metal construction wherein the socket and ⁇ ferrule are formed of relatively malleable metal of high electrical conductivity, such as brass, copper, or bronze, and may be plated or solder-dipped to improve the contact properties of the socket.
  • the Spring is formed from high yield strength spring metal, such as a beryllium copper alloy, stainless steel, or other metals or alloys. The spring holds the pin in the socket and assures that a proper electrical connection is made between the pin and socket.
  • the high electrical conductivity of the socket and ferrule metal aids in eliminating electrical resistance across the connector.
  • the high yield strength of the spring and its elastic spring deformation result in long spring life and the ability to withstand repeated pin insertions without reduction of spring force.
  • the high yield strength of the spring is such that complete attening of the spring against the top of the Socket, such as may occur during insertion of a misaligned pin into the socket, does not stress the spring past its elastic limit and does not result in weakening the spring.
  • Conventional connector of the type disclosed are formed from a single piece of metal stock and are unsatisfactory since it is irnpossible in a one-metal connector construction to achieve the desired electrical properties and spring properties of the bi-rnetal construction taught by the invention.
  • a contact member for an electrical connector comprising an elongated socket formed from relatively malleable sheet metal stock; said socket having a base, two side walls extending upwardly therefrom, a top wall extending between the tops of the side walls at the ends thereof, and means extending from one end of the socket lfor forming an electrical connection with a circuit element; said socket base including stepped portions located adjacent said socket side walls and a disconnect groove located between said stepped portions, said disconnect groove including groove side walls and a bottom wall located at a level below that of said stepped portions, the width of said disconnect groove being less than the interior width of said socket; an elongated spring member formed from resilient sheet metal stock located within said socket, said spring member being bowed longitudinally along the length thereof and the central portion thereof engaging said socket so as to be normally confined by spring tension against said top wall, and locating means for limiting axial shifting of said spring member in said socket whereby upon insertion of a pin contact element in said socket said spring member is elastically stressed by the contact element and holds the contact element in intimate
