Definitions

  • socket connector with gripping elements which possess exceptional ability to adjust to variations in dimensions of the plug connector; to provide a connector with greater contact area with the plug connector; to provide a socket connector with less resistance to entrance of the plug connector without loss of total gripping power; to provide a socket connector with proportionally less movement of the gripping elements under the action of the plug connector with consequent less permanent deformation; to provide a socket connector with gripping elements which possess a better controlled spring grip of the plug connector; and to provide the foregoing objects in a connector which is not more diflicult to produce than previous types of socket connectors, and at no more cost.
  • Fig. 1 is a plan view of our socket connector.
  • Fig. 2 is an end elevation of the same.
  • Fig. 3 is an enlarged longitudinal sectioned view taken in the plane 3-3 of Fig. l, with the plug connector partially inserted therein.
  • Fig. 4 is a similar view with the plug connector fully inserted.
  • Fig. 5 is a sectional view taken in the plane 5-5 of Fig. 4.
  • Fig. 6 is a longitudinal sectioned view of the socket of a modified form of connector.
  • the socket connector 10 comprises a body back portion 12 from which two curled fingers 14 and 14a extend on each side of the body to form four socket receiving clasps.
  • the body in addition, is provided preferably with conductor gripping fingers 16, and insulation gripping fingers 18 for electrically and mechanically securing the insulated wire 19 thereto.
  • the plug connector 20, provided with plug 22, is inserted into the socket connector 10, as shown in Fig. 3.
  • Such plug connector is preferably provided with a dimple 24 on both sides of the plug 22 to permit the plug to be used from either side.
  • An upset portion is formed by coining, through the bottom of the back section 12, to provide a ramp detent 26 which snaps into dimple 24 when in proper position.
  • walls 27 may obviously be provided on the edges 0f the body portion 12.
  • the side walls may extend between the fingers,. as at 29, to control the flexibility-of the fingers.
  • the metal ofthe socket connector may be of brass in the 3/4 hard range, or copper of a similar hardness, which will provide sufficient spring in the fingers to accommodate the plug 22 and grip it adequately.
  • each pair of fingers has adjusted themselves to the tapered end 28 of the plug, and are tilted at a different angle than are the front fingers 14.
  • the front bottom portions 30 of each pair of fingers are preferably charnfered as at 32 to facilitate the plug entrance thereunder.
  • the plug As the plug is further inserted into the socket, it is cammed upwardly as it rides over the detent 26.
  • the leading and rear fingers accordingly, individually adjust themselves until the detent is seated with an audible snap into the dimple, and the plug is properly seated.
  • the rear or underside of the back portion 12 may be recessed or concaved as at 34 during the forming operation, to form a stronger and more resilient socket for the plug connection.
  • each finger to individually adjust to contour irregularities, enables more conducting contact area to be provided.
  • Fig. 6 we disclose a modification of our socket connector in which the leading clasp fingers 114 are connected at the free ends thereof to the rearwardly positioned clasp fingers 114a by means of the integrally formed band 114]).
  • the function of the integral band 11412 is to assist the plug connector 20 in passing from the leading to the rearwardly positioned clasp fingers without the necessity of camming under the rearwardly positioned fingers.
  • the independent action of the fingers is thereby controlled to any desired degree.
  • the connecting integral band prevents the possibility of the rearwardly positioned fingers from becoming accidentally jammed in the operation of the device.
