Definitions

  • a plug and socket electrical connector comprising mating plastic housings and metal terminals housed m m mm mm w L m C5 ms T mm LC E3 M w [52] US. 339/91 R, n. Th housings are provided with interengaging latch 339/110 p members including an apertured tongue on one of the hous- [51 ⁇ Int. g Handle members are Provided on the Same housing for gripping by the thumb and middle finger while the latch is retracted by the index finger to separate the connectors.
  • FIG. 1 is a perspective view showing the two halves of an electrical connector constructed in accordance with the principles of the present invention
  • FIG. 2 is a plan view of the connector in separated position
  • FIG. 3 is a plan view showing the connector with the two portions thereof in connected relation;
  • FIG. 4 is a cross-sectional view taken substantially along the line 44 in FIG. 3;
  • FIG. 5 is a fragmentary sectional view taken substantially along the line 5-5 in FIG. 3.
  • the socket includes a generally rectangular housing of molded thermoplastic construction, such as nylon, including a body 16 and a forwardly projecting insertable end portion 18.
  • the end portion has two chamfered corners 20 for keying with the plug 12.
  • the socket is provided with a plurality of cylinders having bores 22 in which female terminals are received, and these preferably are terminals such as disclosed in the previously mentioned Krehbiel U.S. Pat. No. 3,178,673 and Krehbiel application, Ser. No. 666,299.
  • the forward projecting portion 18 of the socket is provided with a cam-ramp 24 having at its trailing edge a right-angle shoulder 26 serving as a part of a latch cooperable with latch means on the plug 12, hereinafter to be described.
  • the socket 14 is completed by mounting ears or wings 28 extending out at right angles. These ears or wings are the same as those described and claimed in Krehbiel, U.S. Pat. No. 3,196,380 and are provided with transverse channels 30. As set forth in the last'mentioned Krehbiel patent, these ears are capable of being folded back parallel to the adjacent walls of the socket, and thereby to receive the adjacent edges of a mounting panel in the channels 30. It will be apparent that the ears or wings 28 are on sides of the plug that are at right angles to the side on which the latch 24, 26 is disposed. As further will be apparent, wires 32 extend rearwardly of the housing, being connected to the female terminals.
  • the plug also is of generally rectangular construction, including a body 34, having a slightly enlarged forward portion 36 with a cavity 38 therein shaped to receive the forward projection 18 of the socket.
  • the cavity is provided with two chamfered corners 40 complimentary to the chamfered corners 20 for proper keying together of the two connector portions.
  • Male pin terminals 42 are mounted in the plug and extending into the cavity 38, in accordance with the construction disclosed in Krehbiel U.S. Pat. No. 3,178,673 and Krehbiel application, Ser. No. 666,299.
  • Wires 44 extend rearwardly of the plug, respectively being connected to the pin terminals 42.
  • a latch member is provided in the form of an integral, resilient tongue 46 separated from the forward portion 36 of the plug by longitudinal, edge-opening slots 48.
  • the front or free end of the tongue is tipped up at 50 to cam-over the ramp 24 upon assembly of the two connector portions, namely the plug and socket.
  • a recess 52 is provided behind the tipped-up portion 50, in order that the tongue might snap down over the cam-ramp 24 with the rear edge 54 of the tipped-up front portion locking behind the shoulder 26.
  • fins 56 are provided which extend out in opposite directions from one another from the sidewalls 58 which are arranged at right angles to the sidewall in which the tongue 46 is formed.
  • the walls 58 are provided with central thickened portions 60 forwardly of the fins 56, and with a pair of spaced longitudinal ribs 62 rearwardly thereof for reenforcement.
  • the fins in face view, as seen in the right portion of FIG. 1 are tapered somewhat, being narrower at their outer extremities than at their attachment extremities.
  • fillets 64 are formed at the roots of the fins along the front faces thereof for additional reenforcement.
  • the socket when it is desired to separate the plug from the socket, the socket is grasped in the left hand, with the thumb and the index finger respectively engaging the wings 28.
  • the thumb and middle finger of the right hand then engage the fins 56, and the index finger engages the tipped-up end 50 of the tongue, whereby the tongue can be flexed up away from the shoulder 26 while the plug is at the same time gripped by the thumb and middle finger for longitudinal separation of the plug and socket.
  • the flexed position of the tongue is shown in FIG. 5 in broken lines, the latch position being shown in solid lines.
  • An electrical connector comprising a plug element and a socket element telescopically engageable therewith, said socket element including an insulating housing and a plurality of terminals, said plug element including an insulating housing and a plurality of terminals cooperable with said socket element terminals when said plug and socket elements are telescopically engaged together, one of said element housings having a latching shoulder and the other thereof having a cooperating flexible latch member cooperable with the latching shoulder to retain said elements in plugged-in relation with the terminals in cooperating engagement, said flexible latch member comprising an elongated tongue having one end integral with a first side of said housing and having an aperture therein receiving said shoulder, the free end of said tongue extending relatively in the direction of said one housing element and angling out diagonally therefrom for ready manual engagement, as by a finger tip, said other element housing having a pair of oppositely facing protuberances including a plurality of longitudinal ribs for maintaining said protuberances substantially rigid whereby said protuberances are respectively retractably engageable by the
