Appeal No. 2003-2081
Application No. 09/893,931
Appellants’ invention relates to an insulation-displacement terminal fitting. An
understanding of the invention can be derived from a reading of exemplary claim 9,
which is reproduced below.
9. An insulation-displacement terminal fitting, comprising: a base wall,
first and second opposed side walls projecting from opposite sides of the
base wall and defining a wire-receiving space between the side walls, first
and second opposed V-shaped insulation-displacement portions
projecting respectively from the first and second side walls into the wire-
receiving space, first and second substantially planar locks projecting
respectively from the first and second side walls into the wire-receiving
space in positions spaced from the insulation-displacement portions, said
planar locks being aligned substantially normal to the respective side
walls, said first and second locks being formed respectively with first and
second edges defining portions of the first and second locks furthest from
the respective first and second side walls, whereby a wire can be inserted
into the wire-receiving space sufficiently for cutting a resin coating of the
wire by projecting ends of the insulation-displacement portions and
bringing a core of the wire into contact with the projecting ends of the
insulation-displacement portions, and wherein the edges of the locks bite
into at least the resin coating for resisting a pull out force on the wire.
The prior art of record relied upon by the examiner in rejecting the appealed
claims is as follows:
Hoppe, Jr. 3,867,005 Feb. 18 1975
McKee et al. (McKee) 4,040,702 Aug. 9, 1977
Endo et al. (Endo) 5.934,928 Aug. 10, 1999
Claims 9 and 12-14 stand rejected under 35 U.S.C. § 103 as being unpatentable
over Hoppe, Jr. in view of McKee and Endo.
