  • FIGURE 1 shows two insulators in the form of plug boards 1 and 2, the insulator 2 being carried by a frame 3.
  • the insulators are provided with openings 4, which are symmetrical at least with respect to a vertical dividing plane.
  • the openings are adapted to receive prongtype male connectors 5 and socket-type female connectors 6 of suitably complementary configuration.
  • the connectors 5 and 6 are provided with contact-making portions 15 and 16, respectively, and with integral lead-connecting portions 5 and 6, respectively, these portions 5', 6, being connected to leads 8 in any suitable manner, e.'g., by
  • the male connector plugs have flat, blade-like contact-making portions, e.g. portions of rectangular cross section, or they may be round prong-type contact-making portions. If desired, the plugs may be made of two pieces, namely, a contact-making piece which is made of solid material while the piece forming the retaining or arresting region of the connector is made of sheet metal. In practice, however, the plug-type as well as the sockettype connectors are made of a piece of bent sheet material.
  • the openings 4 of the insulators 1 and 2 are so configured that the plugs and sockets can be inserted in any one of the openings and in any position relative thereto.
  • the individual connectors can be introduced into the insulators from either side and in every position, from the right, the left, from the top, the bottom, as desired.
  • the connectors are provided with detent flaps 7 and 7, there being a pair of these flaps on each connector.
  • FIGURES 2, 3 and 4 showing the stamped blank 10 from which the finished sockettype connector, shown in FIGURES 3 and 4, is made.
  • the detent flaps 7, 7' are arranged on a resilient detent tongue 12 which is integral with the remainder of the sheet material forming the socket. Only the top of the tongue 12 is joined to the remainder of the connector.
  • the connector which is elongated, has at one end the contact-making portion 16 and at the other end the lead-connecting portion 14, and that the tongue 12 is joined to the connector at a place thereon intermediate the contact-making and lead-connecting portions.
  • the tongue 12 is a portion of the blank, prior to its being bent to form the finished article, which is laterally of and parallel to the longitudinal axis ;11 of the remainder of the blank.
  • Both of the flaps 7 and 7 are elastically bent outwardly from the same side of the tongue 12; while, as shown, the flaps are out along three edges, they may be out along only two.
  • the flaps 7 and 7' are oriented to act as detents in opposite directions, respectively, so that one detent is effective for preventing removal of the connector from the insulator in one direction and the other detent flap is effective for preventing removal of the connector from the insulator in the opposite direction.
  • the two detent flaps engage the inside and outside, respectively, of an inwardly directed flange 2a of the insulator 2 so that the insulator need not be provided with any further shoulders or flanges. Only the two opposite directly detent flaps, would be needed to fix the position of the connector within the insulator.
  • the shoulder provided at the end of the contact-making portion 16 can be, and preferably is, eliminated from preferred embodi ments of the present invention.
  • the end of the tongue 12 is bent under to form a hook 13, which itself has a manifold purpose.
  • the hook prevents the connecting lead from being pushed too far into the connector during soldering or crimping.
  • the hook also acts against a deformation of the tongue.
  • the hook prevents the detent tongue from freeing itself; on the other hand, the hook can be depressed so as to move the flaps 7, 7' out of the way, whenever it is desired to withdraw the connector, i.e., the tongue 12 is actuatable against its resiliency to move the flaps 7, 7 into a position wherein removal of the connector from the insulator is possible without hindrance on the part of the detent flaps.
  • the lead-connecting portion 14 9f th Qnnector is provided with cut-outs 14'; when the blank is bent into its ultimate configuration, the two cut-outs 14' together form an opening for receiving a drop of solder.
  • the insulator is symmetrical with respect to the axis of symmetry of the blank 11 (FIGURE 2).
  • the contact-making socket 16 of the connector 6 is fashioned as a self-cleaning connector socket and is made up of a plurality of individual and mutually independently resilient tongues 16 and 16". According to a further feature of the present invention, these tongues 16 and 16 are so long that they surround and encompass the male connector prong, i.e., they go beyond the line of symmetry 11 of the socket and circumferentially overlap each other. This affords an especially long spring path, as a result of which the contact-making parts which exert the contact pressure will be less susceptible to fatigue.
  • FIGURE 5 shows the tongues 16' and 16" bent to form a suitable socket for receiving a male connector plug 19 having a rectangular cross section
  • FIG- URE 6 shows these tongues as being bent to form a suitable socket for receiving a round, prong-like male connector plug 20.
  • FIGURE 7 shows the insulator 1 which receives the male connector plug 5.
  • the insulator is shown as having inwardly extending flanges 17, against which abut outwardly extending shoulders of the connector 5; this interengagernent between the connector and the insulator is not needed in order to hold the connector within the plug board and is shown merely to indicate the detent means of the present invention as being suitable for use with conventional, existing plug boards.
  • flanges 17 will be eliminated, as shown in FIGURE 8.
  • FIGURE 8 which shows the interengagement between the flaps 7, 7', and the inwardly directed flange 1a of the insulator 1, also shows that the prong-type connector can be inserted, always with contact-making portion 15 first, into the insulator either as depicted, i.e., downwardly from the top, as viewed in FIGURE 8, or from the bottom; in the latter casewhich can be imagined by considering the insulator 1 as having been turned upside down from the position depicted in FIGURE 8the prong, now indicated in dashed lines at 18, will extend a greater distance beyond the insulator. In this way, two different lengths of prongs can be obtained, which allow the connector arrangement to be used, for example, for grounding an electrical circuit or for serving as a disconnect element.
  • the connector can be inserted with the orientation shown or it can be rotated through an angle of about its longitudinal axis and inserted so that flaps 7 and 7' engage the left-hand flange 1a rather than the right-hand one.
  • FIGURE 9 shows a leaf-spring type connector, the same being provided with an additional lead-connecting portion 21 and an additional detent flap 22, the contactmaking portion of the connector being composed of a plurality of flat, mutually independently resilient tongues.
  • the additional lead-connecting portion 21 allows a double-lead connection.
  • the additional detent flap 22 serves for the same purpose, which accomplishes the same result in a different manner.
  • Two bent leaf springs, each made from the blank shown in FIGURE 9, are nested into each other and are detented to each other, for example by means of the flap 22. Two such nested springs, already provided with the leads, can be inserted into the opening of the insulator, or the second spring can be inserted after the first has been inserted.
  • FIGURES 17 and 18 show a pair of nested springs, of the type shown in FIGURES 9 and 10, already detented in the insulator, with the inner connector being detented, by its flap 22, into a portion 35 of the outer connector.
  • the contacts are adapted to receive, for example, a printed circuit board 23 which is provided with electrical contacts on both sides.
  • FIGURES 13 and 14 show a contact which can be combined with a similarly configured contact to provide a socket for receiving a printed circuit board in such a manner that the electrical circuitry on the two sides of the board are contacted separately and independently of each other.
  • FIGURES 19 and 20 show two pairs of nested contacts, with each contact being formed from a piece according to FIGURES 13 and 14, within the opening of an insulator.
  • FIGURES 11, 12, 15 and 16 show how two nested contacts can be detented to each other by means of a ball 31, 32, 33, or 34. This allows a longitudinal detenting to be released in lateral direction.
  • a connector arrangement in which an electrical connector adapted for insertion into an insulator is provided with at least one resilient tongue carrying at least two detent flaps which are oriented to act as detents in opposite directions, respectively, so that while one fiap prevents withdrawal of the connector from the insulator in one direction, the other flap prevents withdrawal in the other direction.
  • the flaps can, of course, be moved out of the way by depressing the resilient tongue, so that the detent flaps will not interfere with the removal of the connector from the insulator.
  • the structure is very compact, so that it can readily be used in electronic computers and other pieces of equipment where miniaturization is a significant factor.
  • the detent tongue 12 is arranged laterally of the remainder of the connector and, in the finished article, is bent back toward the connector portions proper, there are obtained two separate and mutually independent spring components whose spring actions are additive. Furthermore, this lateral arrangement provides for a more convenient manual access to the tongue which, as explained above, is depressed whenever the detent flaps are to be moved to a position where they will allow the connector to be withdrawn from the insulator.
  • an elongated electrical connector adapted for insertion into an insulator and having at one end a contact-making portion, at the opposite end a lead-connecting portion, and, at a location disposed between said contact-making and lead-connecting portions, tongue means resiliently defiectable with respect to the remainder of said connector and carrying at least two detent flaps, said flaps being oriented to act as detents in opposite directions, respectively, so that one of said detent flaps is effective for preventing removal of said connector from the insulator in one direction and the other of said detent flaps is effective for preventing removal of said connector from the insulator in the opposite direction, said tongue means having only one end joined to the remainder of said connector and being actuatable against its resiliency to move said detent flaps into a posi tion wherein insertion and removal of said connector from the insulator is possible in either direction without hindrance on the part of said detent flaps.
  • said tongue means comprise a single resilient tongue which carries both of said flaps.
  • said contact-making portion comprises a plurality of individual, mutually independently resilient tongues which are bent to constitute said socket.
  • a composite connector comprising a plurality of socket-forming connectors each as defined in claim 9, and detent means for connecting said connectors to each other.
  • a plug connection comprising two connectors each as defined in claim 1, one of said connectors having a contact-making portion which is a socket and the other of said connectors having a contact-making portion which is a prong, said connectors otherwise being configured to be receivable by identically configured insulators, in consequence of which the socket-type connector and the prong-type connector are selectively insertable into standardized insulators.
  • An arrangement as defined in claim 17 further comprising an insulator provided with an opening for receiving said connector and a shoulder at one end of said opening for engaging said flaps.
