  • a terminal screw member 72 is employed to secure electrical contact of a conductor 24a with the clip 18a.
  • Other structural features of the shank 20a are designated by numerals bearing the suffix a corresponding with the numerals employed in FIGS. 1-4, inclusive.
  • FIGS. 7-l3, inclusive a further modification of the clip is shown.
  • the clip disclosed in FIGS. 7l3 inclusive designated generally by the numeral 18b, is similar structurally to the clip 18 previously described.
  • Parts of the clip 18b corresponding with parts of the clip 18 are designated by similar numbers, bearing the sufiix b.
  • the similarity of these corresponding parts will be quite apparent from the drawings.
  • An important distinguishing feature of the clip 18b is the use of an elongated electrical terminal or connector element 74.
  • the upper extremity of the terminal member 74 extends laterally from an elongated portion, as indicated in FIGS. 7, 9, and 11, and is designed to make electrical contact with the arm 52b of the clip member 18b when said arm occupies the position illustrated in FIGS.
  • the terminal member 74 is insulated from the other portions of the clip 18b, and is supported in position by a member 76, made of suitable nonconductive, preferably bendable, material such as a suitable plastic. It will be noted that this member 76 includes a pair of sheath sections 78 adapted to accommodate the upper portion of the conductor 74 when the parts 78 are brought into juxtaposition with the recesses 80 of the sections 78 in registration with each other. The member 76 initially assumes the shape shown in FIGS. 14-16, inclusive.
  • An area 82 of reduced cross-section facilitates bending at this point, enabling each half of the member 76 to be brought into registering engagement with the other companion half.
  • a protuberance 84 when brought into telescopic association with a complementary aperture 86, as sures proper alignment of the recesses 88.
  • the conductor 74 may be assembled within one of the companion recesses 80.
  • a laterally flexible finger or latch member 88 Extending beyond each of the sheath sections 78 is a laterally flexible finger or latch member 88.
  • the member 76 When the member '76 has been folded so as to completely enclose the upper portion of the connector 74, the member 76 may be inserted within the recess 6612, thereby bringing the fingers 88 into interlocking or latching engagement with the hook member 6812, as clearly illustrated in FIG. 13. The member 76 is thus securely held within and electrically insulated from the clip 18b when the arm 52b occupies the position shown in FIG. 9. In this position an electrical conductor such as the conductor 24 previously referred to may be connected with a circuit such as an antenna circuit positioned externally of the panel.
  • the present invention contemplates a sheet metal clip of novel and practical form.
  • the combination of the novel snap-in shank portion with the novel arrangement for detachably accommodating a conductor extremity makes it possible to mount a series of clips within adjacently positioned panel apertures without any danger of short circuits, and with the assurance that the clip will be securely held in proper position upon the panel.
  • the elongated terminal member which may be selectively insulated from or electrically connected with the sheet metal clip, the ease with which antennas or other electrical devices may be selectively coupled with external or internal circuits, is greatly facilitated.
