the elastic piece of the contact pin is extended substantially along a horizontal direction,
the latch includes a pressing portion and a depressing portion integrally formed together,
when the latch is rotated in an opening direction and the electric part is accommodated in the socket body, the elastic piece is pressed downward by the depressing portion of the latch so as to be elastically deformed downward so that the contact portion is displaced downward so as to be separated downward from a contacting position to the terminal of the electric part, and
when the latch is rotated in a closing direction and the electric part is accommodated in the socket body, the electric part is pressed by the pressing portion from an upper side to thereby release a pressing force of the depressing portion of the latch applied to the elastic piece so as to displace the elastic piece upward by the elastic force of the elastic piece to thereby contact the terminal of the electric part.
2. The socket for electric part according to claim 1, wherein
the latch comprises a pair of rotation shafts disposed along a same axis, to thereby provide said rotation shaft about which the latch is rotatable, and
the depressing portion of the latch is a cam portion provided between the rotating shafts.
3. A socket comprising:
a socket body that accommodates an electric part including a terminal;
a contact pin provided for the socket body and formed with an elastic piece comprising a contact portion to contact the terminal of the electric part when the electric part is accommodated in the socket body; and
a latch which is rotatable about a rotation axis and configured to press the electric part, when the electric part is accommodated in the socket body, from an upper side of the socket body, wherein
the latch includes a pressing portion and a depressing portion integrally formed together,
when the latch is rotated in an opening direction and the electric part is accommodated in the socket body, the elastic piece is pressed downward by the depressing portion of the latch so as to be elastically deformed downward so that the contact portion is displaced downward so as to be separated downward from a contacting position to the terminal of the electric part, and
when the latch is rotated in a closing direction and the electric part is accommodated in the socket body, the electric part is pressed by the pressing portion from an upper side to thereby release a pressing force of the depressing portion of the latch applied to the elastic piece so as to displace the elastic piece upward by the elastic force of the elastic piece to thereby contact the terminal of the electric part.
4. The socket according to claim 1, wherein
the latch comprises a pair of rotation shafts disposed along the rotation axis, and
the depressing portion of the latch is a cam portion provided between the rotating shafts.
The claims below are in addition to those above.

26. An apparatus for permanently attaching an overlay having an outboard surface, an inboard surface, an outer diameter, an inner diameter, a valve stem opening, at least one turbine opening, and a flange area about the outer diameter, to a wheel having an outboard surface on a wheel disc, an outer wheel flange, a rim flange, a valve stem opening, a fill port, at least one turbine opening, a hub bore, and a bolt pattern, said apparatus comprising:
a fixture for locating said wheel;
first means for clamping said wheel to said overlay, said clamping means being attached to said fixture and locating said overlay to said wheel, said outboard surface of said wheel and said inboard surface of said overlay defining a cavity therebetween;
a first set of nests aligned with and contacting said overlay and said wheel, said first set of nests having a bottom nest, a valve stem nest adjacent said bottom nest and at least one turbine opening nest aligned with said at least one turbine opening, said bottom nest generally conforming to said outboard surface of said overlay, said valve stem nest and said at least one turbine opening nest closing off said valve stem opening and said at least one turbine opening;
a second set of nests comprising a center bottom nest generally conforming to said inner diameter of said overlay and said bolt pattern of said wheel wherein said second set of nests create a seal by means of expanding radially when compressed in an axial direction against said wheel;
a movable pallet positioned under said fixture for locating said overlay to said wheel;
first means for clamping said overlay and said wheel to said movable pallet;
second means for clamping disposed around said wheel and said movable pallet, said second means for clamping comprising:
an upper stationary platen having a fill port, said upper stationary platen contacting a surface of said wheel disc; and
a lower moving platen contacting said movable pallet wherein said wheel, said overlay and said movable pallet are clamped between said upper stationary and said lower moving platens of said second means for clamping; and
a foam filling station for filling said cavity with a foam material, said foam filling station having a nozzle mounted to said upper stationary platen of said second means for clamping, said nozzle being in communication with said fill port of said wheel.
27. A process for permanently attaching an overlay having an outboard surface and an inboard surface to a wheel having an outer surface and at least one predefined opening therein, said process comprising the steps of:
locating said overlay in a fixture;
positioning said wheel on said inboard surface of said overlay defining a cavity between said outer surface of said wheel and said inboard surface of said overlay, said overlay having at least one predefined opening therein, said at least one predefined opening of said wheel peripherally surrounding said at least one predefined opening of said overlay;
clamping said overlay and wheel to a pallet;
heating said overlay and said wheel to a predetermined temperature;
engaging at least one localized nest in said at least one predefined opening of said overlay and said at least one predefined opening of said wheel so as to create a localized area of said cavity between said inboard surface of said overlay and said outer surface of said wheel, whereby a mold is made of said cavity;
injecting a foamable liquid in to said cavity;
curing said foamable liquid;
disengaging said localized nest; and
unclamping said wheel and said overlay from said pallet.
28. The process as claimed in claim 27 further comprising the step of clamping said wheel to said overlay after positioning said wheel on said overlay, said clamping steps defining a cavity between said overlay and said wheel, said cavity having a plurality of openings.
29. The process as claimed in claim 27 wherein said step of heating said overlay and said wheel further comprises heating said overlay and wheel to a predetermined temperature within the range of 90\xb0 F. to 190\xb0 F. before said step of injecting said predefined quantity of foamable liquid.
30. The process as claimed in claim 27 further comprising the step of applying an adhesive sealant to said inboard surface of said overlay before said step of positioning said wheel on said inboard surface of said overlay.
