Definitions

  • the present invention relates to a grounding plate for a plug.
  • Fig. 1 of the drawings illustrates a typical three-pole plug includes positive and negative prongs 11 and 12 and a grounding plate 13 having a hole 131.
  • the plug is engaged with a receptacle, with the positive and negative prongs 11 and 12 being engaged with two slots of the receptacle, and with a prong on the receptacle being inserted through the hole 131 of the grounding plate 13, providing a grounding effect.
  • the grounding plate of this type includes a metal plate that is bent to a desired shape for engaging with a semi-product of a plug by means of insertion or other suitable means.
  • the grounding plate has a tubular core-receiving member provided thereon for receiving a grounding wire that includes a plurality of cores covered by a layer of plastic material. It was found that some of the cores of the grounding wire extended radially outward and thus could not be smoothly extended into the tubular core-receiving member. The insertion operation of the cores of the grounding wire was thus adversely affected.
  • Figs. 2 through 4 illustrate a grounding plate 2 disclosed in DE 39 11 316 C2.
  • the grounding plate 2 includes a tubular core-receiving member 21 having a conic end portion 211 for guiding the cores 212 of a grounding wire.
  • the cores 212 are covered by a plastic layer that is cut at an end thereof to expose the cores 212 before the insertion operation of the grounding wire. Nevertheless, if the cut length of the plastic layer is not precisely controlled or if the machine for proceeding with the insertion operation or the workpiece is undesirably moved, the plastic layer is pushed by the machine, resulting in unreliable positioning of the cores.
  • An object of the present invention is to provide a grounding plate for a plug, allowing reliable positioning of a grounding wire during an insertion operation of the cores of the grounding wire into a wire-receiving tubular member of the grounding plate.
  • a grounding plate for a plug is a metal plate and includes a tubular core-receiving member provided thereon for receiving cores of a grounding wire.
  • the tubular core-receiving member includes a flange on an outer end thereof.
  • the flange has a diameter greater than a main body of the tubular core-receiving member.
  • the cores of a grounding wire are extended through the tubular core-receiving member and an end of a plastic layer of the grounding wire abuts against the flange in an insertion operation of the grounding wire. This provides a restraining effect for the grounding wire and allows stable operation.
  • Figs. 6 and 8 show a grounding plate 3 in accordance with the present invention that is a metal plate bent to an appropriate shape.
  • the grounding plate 3 is coupled with an inner frame 4 (Figs. 5 and 7) to form a plug (not shown) after subsequent manufacturing procedures.
  • the grounding plate 3 includes a tubular core-receiving member 31.
  • the tubular core-receiving member 31 includes a flange 311 on an outer end thereof.
  • the flange 311 has a diameter greater than that of a main body of the tubular core-receiving member 31.
  • Figs. 12 through 14 illustrate a modified embodiment of the tubular core-receiving member (now designated by 31A), wherein the flange (now designated by 311A) has a curved outer edge 312A.
  • Figs. 15 through 17 illustrate another modified embodiment of the tubular core-receiving member (now designated by 31B), wherein the outer edge of the flange (now designated by 311B) bends rearward and thus has a section 312B extending in a direction parallel to the main body of the tubular core-receiving member 31B.
