Definitions

  • a broad object of the invention is to provide a miniature connector including a pin contact and a socket contact, each of a one piece sheet metal stamping and mountable in a connector block by the mere act of inserting it thereinto, and releasably held in such position.
  • Another object is to provide a miniature connector including a pin contact and a socket contact which are interchangeably usable in the same connector block, whereby to enable the use of a pair of identical connector blocks for mounting the contacts and either selectable at random for either the pin contacts or the socket contacts.
  • Another and more specific object is to provide a miniature connector including a pin contact and a socket contact having substantially identical construction insofar as their mounting in a connector block are concerned, and in which each includes a tubular portion havingslots forming ribs, in which the ribs are yieldable radially and enable releasable interlocking engagement between the contact and a connector block in which it is mounted, whereby either pin contact or socket contact can be mounted selectively in the same hole in the connector block.
  • Still another object is to provide a miniature connector of the foregoing general character in the use of which it is not necessary to utilize any external means, or any means other than the contact itself, for securing the contact in a connector block.
  • a still further object is to provide a miniature connector of the foregoing general character, including a pin contact and a socket contact each of one piece construction and therefore extremely economical, both from the standpoint of manufacture in thatit can be easily made in a punch press operation, and from the standpoint of its use after its manufacture, in that there is no need for assembling pieces to form the contact, or to utilize additional pieces for mounting or securing it in the connector block.
  • An additional object is to provide a connector block having novel construction for utilization with the contacts of the foregoing character.
  • FIG. 1 is a view of the contacts of the connector mounted in connector blocks, the connector blocks being shown in section and fitted together, and the contacts in elevation and interconnected;
  • FIG. 2 is a view similar to FIG. I, on a larger scale, but showing only the central portion of FIG. 1 and the connector block separated and the contacts disconnected;
  • FIG. 3 is a sectional view taken at line 3-3 of FIG. 2;
  • FIG. 4 is a sectional view taken at line 4-4 of FIG. 2;
  • FIG. 5 is a sectional view taken at line 5-5 of FIG. 2.
  • FIG. 6 is a sectignalyjew taken on the line 6-6 of FIG. 1.

  • Each connector block 10 is provided with a hole or aperture 14 therethrough, preferable cylindrical in shape and uniformly so except for a circumferential detent bead or rib 16 having inclined shoulders 17 spaced from the front face 13 at a predetermined distance as will be referred to again hereinbelow in connection with the positioning of the connector contacts therein.
  • the connector is indicated as a whole at 18 and includes a socket contact 20 and a pin contact 22.
  • These contacts are substantially identical or similar in construction insofar as their mounting in the connector blocks is concerned, but they have different fore portions for interengagement as referred to hereinbelow.
  • Each contact includes a rear portion 24 and an intermediate portion 26 substantially identical in the two contacts, while the socket contact 20 includes a fore portion 28 forming a socket element and the pin contact 22 includes a fore portion 30 forming a pin for insertion into the socket element ofthe socket contact.
  • Each contact is made of a single piece, sheet metal stamping, formed into a tubular shape preferably cylindrical as here shown.
  • the rear portion of each contact includes relatively long prongs 32 adjacent its rear end, forwardly of which are shorter prongs 34, together forming a crimp pocket by which the connector is secured on the conductor stripped at its end, the shorter prongs 34 being crimped on the wire element 36a and the longer prongs 32 crimped on the insulation 36b.
  • That part of the stamping that forms the central portion 26 is provided with slots 38 forming a plurality of longitudinally extending ribs 40 between adjacent slots, and upon shaping the piece into tubular form, the ribs are circumferentially spaced, the ribs possessing substantial yieldability or resilience in radial direction.
  • Rearwardly of the slots is a portion 42 that is unslotted and in this portion the side edges of the stamped piece are brought into abutting engagement as indicated at 44 in FIG. 6, the side edges being relieved to facilitate abutting engagement.
  • This portion 42 provides a rigid and nonyielding segment.
  • the ribs 40 intermediate their length are provided with radially inwardly offset segrnents 46 of short longitudinal extent and together forming a circumferentially extending recess receiving the bead 16 in the connector block as referred to again hereinbelow.
  • the elements 48 interconnecting these offset segments and the main portions of the ribs are inclined, similarly to the shoulders 17 of the bead.
  • the outer surface of the ribs 40, and of the rigid portion 42 preferably lie in a common cylindrical surface defining the outermost dimension of the contact, and dimensioned slidable insertion into the hole or aperture 14 in the connector block.
  • the prongs 32 when crimped on the insulation form an outer cylindrical surface of substantially the same dimension.
  • the ribs 40 have forwardly inclined elements 49 leading into the fore portion 28 which is unslotted and of reduced diameter and less than the aperture through the bead 46.
  • the side edges of the stamping in this portion 28 are brought into abutting engagement as indicated at 50 in FIG. 3, and in this case also the side edges may be relieved for facilitating abutting engagement.
  • the meeting edges of this portion 28 are provided with a dovetail interlocking connection 52 to aid in rigidifying it and to prevent its expansion.
  • the spacing of the detent recess 46 from the front end of the socket contact, and the spacing of the bead 16 from the front face 13 of the connector block, are substantially the same whereby to position the front end of the contact adjacent the front face of the block for cooperation with the pin contact 22 as referred to again hereinbelow.
  • the fore portion 30 is unslotted and rigid, and of reduced diameter, less than the aperture through the bead 16, and forwardly of the portion 30 is a pin including a pair of fingers 54 separate and detached from each other and having a high point 56 or maximum dimension greater than the internal diameter of the socket element 28 of the socket contact.
  • the fingers 58 are of a construction heretofore known, self biased outwardly to the maximum dimension but collapsible or otherwise deflectable in response to insertion into the socket element.
  • the beads 16 in both connector blocks are spaced from the front face 13 the same distance, and the dimensions and proportions of the pin contact are such that when the detent recess 46 is in engagement with the head 16, the pin fingers 56 extend forwardly beyond the front face 13 of the block so that when the blocks are fitted together with their front faces interengaged, the pin fingers extend into the socket element in the socket contact.
  • the inclined elements 49 of the ribs upon engaging the bead 16 cams the ribs inwardly to enable the outer portions of the ribs to pass the bead, upon insertion of the contact into the hole 14.
  • the front camming elements 48 of the detent segments 46 similarly cam or deflect the ribs inwardly.
  • the elements 48 by engagement with the inclined elements 47. serve to normally retain the contacts in proper position, but enabling withdrawal thereof. This interengagcment in itself maintains the contacts in the said position, without the necessity for additional elements such as clips etc. for the purpose.
  • each contact together with the absence of any additional elements such as clips, renders the contacts extremely inexpensive to manufacture since they can be made easily by punch press operation, and the use thereof is facilitated by the absence of the necessity for assembling a plurality of pieces to make the contacts, or using a plurality of pieces for securing them in position in the connector or blocks.
  • An electrical contact comprising a tubular member having a rear portion for connection with a conductor. a fore portion for contact engagement with another contact, and a central tubular portion having a normal outer diameter yieldable radially inwardly, and having a detent element lying out of said normal surface cooperable with a counterpart detent element in a connector block hole in which it is insertable, for releasably retaining the contact in the hole, wherein said central tubular portion is provided with slots forming a plurality of longitudinally extending circumferentially spaced ribs, the ribs being flexible and providing the yieldability, said detent element in the contact being incorporated in said ribs intermediate the ends thereof. and the contact having end portions longitudinally beyond the ribs that are circumferentially continuous and radially rigid.
