Definitions

  • the present invention relates generally to electn'cal connectors having mating connector members with pin and socket contact elements or terminals mounted therein, respectively, and the invention relates more particularly to a novel electrical connector construction wherein the contact elements or terminals can be snapped into and out of their operative positions in the connector bodies.
  • One of the principal problems which must be contended with in connection with contact terminals which are adapted to be inserted into a connector body after the ends of the conductor wires have been connected to the terminals as by crimping or soldering, is to provide engaging means between the individual terminals and the connector body which will securely hold the terminals in fixed positions in the body during engagement and disengagement of the connector members.
  • prior art devices of this general type have provided engaging means between the individual terminals and the connector body portions which cause the terminals to be permanently locked in their operative positions in the body portions so that the terminals could not be removed without dismantling or disassembling the connector members or without using special removal tools which require undesirable working clearances in the connector members.
  • Another object of the present invention is to provide an electrical connector having pin and socket contact terminals which are insertable from the rear or conductor Patented Sept. 5, 1961 ends of the connector body portions into axial bores through the connector body portions, the pin and socket terminals each having an annular groove thereon in which is mounted a resilient retaining ring, the retaining ring being compressed radially-inwardly as the terminal is inserted into its respective bore in a connector body portion, and then snapping radially-outwardly in front of an an nular surface in the body portion which will normally hold the terminal against rearward movement in the connector under the rearwardly directed force imposed upon the terminal by the coupling thereof with a mating terminal, this annular body portion surface being.
  • Another object of the present invention is to provide an electrical connector of the character described wherein the forwardly-directed annular retaining face in each terminal-receiving bore of the connector body tapers for wardly and outwardly so as to provide a cam surface for constricting the retaining ring radially-inwardly to a smaller diameter upon the application of a sufiicient rearward force to the terminal for removal of the terminal from the body, and wherein the opposed, rearwardlyfacing surface of the terminal groove likewise tapers forwardly and radially-outwardly, but at a steeper angle relative to the axis of the terminal and terminal bore than the retaining face and the bore, whereby the rearward removal force on the terminal will cause this tapered terminal groove surface to apply a radially-outwardly directed expanding force to the retaining ring which tends to oppose the radially-inwardly directed camming force of the tapered bore surface, whereby the ditlerence in the angles of taper relative to the axis between the said rearwardly-facing
  • a further object of the present invention is to provide an electrical connector of the character described wherein each terminal-receiving bore of the connector body portions is provided with a rearwardly and outwardly-flaring annular entrance ramp which is relatively gradual so as to constrict the retaining ring into the terminal groove, thereby permitting easy insertion of the terminals into the terminal-receiving bores in the connector bodies; control of the slope of this annular entrance ramp and of the forwardly-facing side of the terminal groove which forces the retaining ring against the entrance ramp providing accurate control over the amount of insertion force required.
  • FIG. 1 is an axial section of an electrical connector embodying the present invention and showing the two connector members thereof operatively interengaged;
  • FIG. 2 is a detail axial section on an enlarged scale, illustrating a pin contact terminal operatively engaged in a terminal-receiving bore in one of the connector members;
  • FIG. 3 is a detail axial section on an enlarged scale illustrating a socket terminal operatively positioned in the other connector member
  • FIG. 4 is a transverse section along the line 4-4 in FIG. 2;
  • FIG. 5 is a greatly enlarged detail axial section illustrating a portion of the structure shown in FIG. 2 so as to particularly illustrate the relationship of the surfaces in the terminal groove which receives the retaining ring and in the terminal-receiving bore, in a presently-pre- --ferred form of the invention
  • FIG. 6 is a detail axial section similar to FIG. 2, but illustrating an alternative form of the invention embody- .ing a molded-in contact retention sleeve;
  • FIG. 7 is an axial section generally similar to FIG. 3,
  • the connector body includes a plurality of insulation block members.
  • the connector 10 includes a receptacle connector member 12 and a plug connector member '14 which is receivable in the receptacle member 12.
  • the receptacle connector member 12 includes an openended tubular shell 16 having an outer flange 7.8 for mounting purposes, and having a forward skirt portion 26 gadapted to receive the plug connector member 14.
  • receptacle shell 16 is provided with an inside flange 22 disposed to the rear of the forward skirt portion 20, and
  • An insulation body 26 is mounted within shell 16, the body 26 having a forwardlyfacing shoulder 28 which engages against inside flange 22 so as to limit the insulation body 26 against forward ,movement in the shell 16.
  • the periphery of rear face .30 of insulation body 26 is engaged by a snap ring 32 which seats in groove 24 so as to hold the insulation body 26 against rearward movement in the shell 16.
  • a plurality of pin contact elements or terminals 34 are operatively positioned in respective axial bores 36 through insulation body 26, these pin contact elements or terminals 34 being removably-engaged in the respective axial bores 36 in the manner hereinafter described in detail.
  • the connector 10 illustrated in the drawings has the pin contact terminals mounted in the receptacle member 12 and the socket contact terminals mounted in the plug connector member 14, it will be obvious to those skilled in the art that the socket terminals could be supported in the receptacle connector member and the pin terminals could be supported in the plug connector member, without in any Way departing from the present invention.
  • a plurality of conductor wires 38 are both mechanically and electrically connected to the pin contact terminals 34 by engagement of the ends of conductors 33 in solder or crimping cups 40 at the rear ends of the contact terminals 34.
  • the receptacle shell 16 may be provided with an externally-threaded rear portion 42 which is adapted to receive a conventional internal sealing grommet and an end bell, these parts being of conventional construction and therefore not being shown in the drawings.
  • the terminal 34 is also provided with an external'flange 86 which is positioned substantially to the rear of groove 78 and which serves to limit the forward travel of the terminal in the bore 36.
  • this forwardly-directed face 88 By inclining the forwardly-directed bore face or shoulder 88 so that it extends forwardly and radially-outwardly from the most constricted portion 89 of the bore, this forwardly-directed face 88 provides a cam surface against which the retaining ring 80 is compressed radially-inwardly within the terminal groove 78 when the terminal is pulled or pushed rearwardly, so that the ring 80 will be reduced in diameter to a size permitting the ring to pass rearwardly through the constricted portion 89 of the bore 36, allowing complete rearward extraction of the terminal 34 from the body of the connector.
  • the forwardlydirected bore face 88 would permanently lock the terminal in its seated position within the body, and attempts to remove the terminal by merely pushing or pulling it rearwardly would tend to shear and damage the ring, and also would damage the holding face in the bore, and the opposed portion of the terminal.
  • FIG. 3 of the drawings illustrates the present invention as applied to one of the socket terminals 66 in the insulation body 58 of plug connector member 14.
  • the socket terminal may have a forward socket portion of any desired type, the socket portion 98 of the illustrated terminal 66 being of the type which has an external portion 106 of reduced diameter about which is disposed a spring-gripping member 1&2, a portion of which extends through the wall of the socket terminal so as to resiliently engage a respective pin contact element.

  • the ring a is cammed radially-inwardly by the gradually slop- 7 ing'annular entrance ramp 92a and rides past the most constricted portion 89a of the bore, snapping radiallyoutwardly just in front of forwardly and inwardly-directed annular face 88a in the bore so as to lock the terminal in position.
  • a counter-bore portion 90a of the bore 68 extends forwardly from the annular surface Sfia to the forward face 164 of insulation body 58.
  • the socket terminal 66 is limited in its forward travel through insulation body 58 by engagement of flange 86a against rearwardly-facing surface 94a in the bore. the flange 86a being accommodated in rear counterbore 96a which extends rearwardly from surface 94a to the rear face '62 of the insulation body.
  • FIGURE 6 of the drawings illustrates a modified form of the present invention which employs a. molded-in contact retention sleeve composed of metal which lines the portion of each terminal-receiving bore that engages and cooperates with the retaining ring.
  • This molded-in contact retention sleeve is suitable for an insulation body of any insulating material, but is particularly desirable where the insulation body is composed of an elastomer material which, because of its resilience, might otherwise be damaged by the retaining ring, or might result in an unpredictable withdrawal force required to remove a terminal.
