Appeal No. 2005-1571 6
Application No. 10/263,275
13, 18 and 26, requiring the multi-size transformer stud
receiving passageway to be defined in part by a smooth or
unthreaded arcuate bottom which bifurcates a lowermost threaded
stud landing. To overcome this deficiency, the examiner turns to
Kraft.
Kraft, which is acknowledged as prior art by Ashcraft (see
column 1, lines 51 through 55), discloses a transformer stud
electrical connector 20 having an over-sized threaded aperture 40
designed to be slid over a threaded transformer stud 38 and
clamped thereto by a set screw 42. The configuration of the
aperture 40 ensures a secure connection with the stud 38:
[t]o facilitate stability of the locking
interengagement, aperture 40 is provided with a
U-shaped groove or recess 54 formed in its bottom
portion with the center of the U-shaped recess 54 in
alignment with the axis of the threaded lower end
portion 52 of set screw 42. The recess extends
sufficiently along the length of aperture 40 so that it
is in vertical alignment with the press screw. Thus,
when set screw 42 is threaded downward into engagement
with stud 38 as shown in FIGS. 2 and 3, it will engage
the top of the stud 38 and the stu[d] bottom will be
engaged at two points, the two edges 56 and 58 at both
sides of the U-shaped groove 54. A three point contact
is made with the stud 38 with points 56 and 58 being
offset from the direct vertical point contact at the
end of set screw 42 so that a triangular configuration
of forces is provided to hold the stud in position and
resist movement from any forces applied to the
connector [column 3, lines 26 through 43].
