Claims 2-10, dependent on an amended claim, are determined to be patentable.
New claims 11-12 are added and determined to be patentable.
1. A coring system for producing a [ die-cast or injection molded ] flash free one-piece connector body for securing electrical cables to a panel comprising:
a first core including a base portion, a tubular nose portion [ integral with and ] extending from said base portion to a shoulder, and an end portion narrower than said base portion extending from said shoulder;
a second core including a [ common ] base portion and two substantially parallel and generally tubular [ cylindrical ] fingers extending from said [ common ] base portion to an end; and
said first core capable of engaging said second core in such a manner that said narrow end portion of said first core extends between said fingers of said second core and said end of said fingers of said second core engages said shoulder on said first core in a gap free connection,
whereby said engaged cores are capable of being inserted in the cavity of a mold that is capable of being closed and having molten metal or plastic admitted therein into said cavity thereby producing said flash free one-piece connector body.
[ 11. A coring system for producing a flash free one-piece connector body for securing electrical cables to a panel comprising:
a first core including a base portion, a tubular nose portion extending from said base portion to a shoulder, said nose portion necked down to a smaller diameter than said base portion, and an end portion narrower than said base portion extending from said shoulder;
a second core including a base portion and two substantially parallel and generally tubular fingers extending from said base portion to an end, said fingers necked down to a smaller overall diameter than said base portion; and
said first core capable of engaging said second core in such a manner that said narrow end portion of said first core extends between said fingers of said second core and said end of said fingers of said second core engages said shoulder on said first core in a gap free connection,
whereby said engaged cores are capable of being inserted in the cavity of a mold that is capable of being closed and having molten metal or plastic admitted therein into said cavity thereby producing said flash free one-piece connector body.]
[ 12. A coring system for producing a flash free one-piece connector body for securing electrical cables to a panel comprising:
a first core including a base portion, a tubular nose portion extending from said base portion to a shoulder, and an end portion narrower than said base portion extending from said shoulder;
a second core including a base portion and two substantially parallel and generally tubular fingers extending from said base portion to an end;
two grooves on opposing sides of said end portion of said first core; and
said first core capable of engaging said second core in such a manner that said narrow end portion of said first core extends between said fingers of said second core and said end of said fingers of said second core engages said shoulder on said first core in a gap free connection,
whereby said engaged cores are capable of being inserted in the cavity of a mold that is capable of being closed and having molten metal or plastic admitted therein into said cavity thereby producing said flash free one-piece connector body.]
