Panelboard 15 is wired by a cable assembly 20 connected to certain ones of the contact elements, i.e., ground rails 18 and pins 17.
  • Cable assembly 20 includes connector assemblies 210 and 21b at opposite ends thereof.
  • Each connector assembly includes a holder 22 connected to a plurality of housings 23, which contain the connector elements or contacts for making the electrical connection to ground rails 18 and terminal pins 17.
  • a plurality of cables 24 extend between connector assemblies 21.
  • Holders 22 each include a portion that can be grasped between the thumb and index finger whereby the holder can be used to pull or disconnect the connector assembly 21 from the panelboard 15 and to initially connect it to panelboard 15.
  • holders 22 unite the various cables 24 and housings 23 of the cable assembly to form a unit.
  • the individual housings 23 are interlocked with holder 22 and can be selectively separated therefrom.
  • cable assembly 20 comprises connector assemblies 21a and 21b interconnected by six cables Z ta-24f.
  • the connector assemblies comprise holder 22a engaged with housings 23a-23f and holder 22b engaged with housings 23g23l.
  • the housings 23 of each connector assembly are of shallow cubical or box-like shapes and are supported on the associated holder in parallel, adjacent, side-byside relationships.
  • each cable 24 contains three wires or conductors 25 enclosed in an insulated sheath 26, the sheath being shaped, scored or weakened throughout its length so that the ends of the cable can be readily parted and stripped of insulation to bare the individual wires.
  • the two outer wires 25 are attached mechanically and electrically to a contact 27, housed in housing 23, and the central wire is connected to a contact 28.
  • Contacts 27 and 28 are known as fork connectors whose tines are substantially flat and lie in a common plane.
  • Housing 23 has a slot 29 shaped to fit over a ground rail 18 so that contact 27 can be electrically connected thereto.
  • the housing 23 also has a hole 30 shaped to fit over a terminal pin 17 so that contact 28 can be electrically connected thereto.
  • contacts 27 and 28 and cable 24 are embedded in a non-conductive body 31 molded thereabout. A portion of body 31 projects from housing 23. The outer edges of the tines of contacts 27 and 28 lock with retaining edges 32 on the housing so as to prevent the contacts from being pulled from housing 23 except by use of a suitable tool or excessive force.
  • each slot includes reduced width end portions 39 and 40 and an enlarged width medial portion 41.
  • the size and shape of slot 38 is related to the size and shape of tab 34 so that housing 23 can be joined or connected to holder 22, in a manner more fully described in reference to FIGS. and 11 below, by engaging tab 34 in slot 38.
  • the width W1 (FIG. 7) of head 36 of tab 34 is substantially equal to the width W2 (FIG. 8) of medial portion 41 of slot 38.
  • the width of neck 35 is substantially equal'to the width W3 of portions 39 and 40.
  • the length L1 (FIG.
  • neck 35 is substantially equal to the lengths L2 and L3 (FIG. 8) of portions 39 and 41 and is greater than the length L4 of end portion 40.
  • the thickness t (FIG. 9) of holder 22 is about the same as the height h (FIG. 6) of neck 35.
  • Tabs 34 and slots 38 are so dimensioned as to provide sliding fits therebetween. To accomplish this, the corresponding dimensions of tab 34 are slightly less than those of slot 38, in a manner well-known in the art.
  • head 36 is longer than neck 35 to provide an overhanging lip.
  • tab 34 of the housing is first aligned with the medial portion 41 of a slot 38, as shown in FIG. 9 by the dotted position of housing 23.
  • the housing is then moved so that the lip portion of head 36 passes through portion 41 until the rear of tab 34 abuts the underside of those portions of holder 22 surrounding the inner end of portion 40, as shown by the full line position of housing 23 in FIG. 9.
  • the lefthand portion of housing 23, as viewed in FIG. 10 is moved to the left from the dotted position, in the direction of arrow a so that neck 35 enters portion 39.
  • housing 23 is pivoted upwardly in the direction of arrow b until the topside of the main body portion of housing 23 abuts the underside of holder 22, as shown by the full line position of housing 23 in FIG. 10.
  • housing 23 can be moved relative to holder 23 by sliding the tab 34 along slot 38 between the two extreme end positions. The reverse of this sequence of movements can be used to disconnect the housing from the holder.
  • the housing may also be disconnected as described below.
  • holder 22 is gripped between the thumb and index finger.
  • the flexibility of holder 22 permits the index finger to be inserted between it and cables 24.
  • the housings are then aligned to fit over the respective pins 17 and ground rail 18 and the assembly is moved or pushed in a downward direction.
  • This downward movement causes housing 23 to abut the end of portion 39 of slot 38 whereby the pushing motion is transferred from holder 22 to housing 23 through the end of neck 35.
  • the downward movement is continued until holder 22 reaches the position shown in FIG. 11, wherein the lower end of holder 22 abuts the top surface of printed circuit board 16 so that the final pushing force is not exerted directly against pins 17 and ground rail 18.
  • holder 22 In order to disconnect the connector assembly 21 from panelboard 15, holder 22 is grasped, as shown in FIG. 12, in a manner similar to that used to push the connector onto the panelboard and it is pulled upwardly. This upward movement will cause the holder 22 to initially slide relative to housings 23 until the ends of portions 40 of slots 38 abut the lower end of necks 35. From this point on, further upward movement disconnects the connector assembly 2i from ground rail 18 and terminal pins 17.
  • each holder 22 may be notched as indicated at 45 in FIG. 8, and this edge can be used to provide a quick visual check that all of the connector assemblies 21 mounted on panelboard 15 are in the correct position.
