Abstract
Abstract A structure for electrical connection of an electric part includes a contact probe retained in a through-hole formed in a base member such that the contact probe can be compressed into the through-hole in an axial direction of the through-hole and restored therefrom, and an intermediate contact member turnably supported by the base member through a cantilevered-arm interposed between the contact probe and a contactor of the electric part.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
186 words
A structure for use in electrical connection of an electric part, said structure comprising: a base member having a through-hole formed therein; a longitudinally compressible contact probe mounted in said through-hole of said base member so as to protrude upwardly therefrom when in an uncompressed state; an intermediate contact member having a first extreme end and a second extreme end, said first extreme end constituting a fulcrum and being rotatably attached to and supported by said base member such that said intermediate contact member is pivotable about said first extreme end between a rest position in which said second extreme end is in an upper position and a compressing position in which said second extreme end is in a lowered position; wherein said intermediate contact member includes a contact point at which said intermediate contact member contacts a protruding end of said compressible contact probe; and wherein said fulcrum at said first extreme end of said intermediate contact member is disposed at a level below a level of said contact point when said intermediate contact member is in either said rest position or said compressing position.
Claim 2
Dependent Claim
186 words
A structure for use in electrical connection of an electric part, said structure comprising: a base member having a through-hole formed therein; a longitudinally compressible contact probe mounted in said through-hole of said base member so as to protrude upwardly therefrom when in an uncompressed state; an intermediate contact member having a first extreme end and a second extreme end, said first extreme end constituting a fulcrum and being rotatably attached to and supported by said base member such that said intermediate contact member is pivotable about said first extreme end between a rest position in which said second extreme end is in an upper position and a compressing position in which said second extreme end is in a lowered position; wherein said intermediate contact member includes a contact point at which said intermediate contact member contacts a protruding end of said compressible contact probe; and wherein said fulcrum at said first extreme end of said intermediate contact member is disposed at a level below a level of said contact point when said intermediate contact member is in either said rest position or said compressing position.
Claim 3
Dependent Claim
59 words
A structure as recited in claim 1, wherein said intermediate contact member constitutes a means for longitudinally compressing said contact probe upon being pivoted from said rest position to said compressing position; and said contact probe is longitudinally resilient so as to constitute a means for restoring said intermediate contact member to said rest position from said compressing position.
Claim 4
Dependent Claim
20 words
A structure as recited in claim 1, wherein an entirety of said intermediate contact member is pivotable about said fulcrum.
Claim 5
Dependent Claim
28 words
A structure as recited in claim 1, wherein said intermediate contact member includes a stopper for setting an upper limit for pivotal movement of said intermediate contact member.
Claim 6
Dependent Claim
16 words
A structure as recited in claim 1, wherein said intermediate contact member comprises a spring member.
Claim 7
Dependent Claim
18 words
A structure as recited in claim 1, wherein said contact probe comprises a rod formed of entangled wires.
Claim 8
Dependent Claim
23 words
A structure as recited in claim 1, wherein said contact point is located adjacent said second extreme end of said intermediate contact member.
Claim 9
Dependent Claim
25 words
A structure as recited in claim 1, wherein said contact point is located intermediate said first and second extreme ends of said intermediate contact member.
Claim 10
Dependent Claim
17 words
A structure as recited in claim 1, wherein said contact point is spaced apart from said fulcrum.
Claim 11
Dependent Claim
165 words
A structure for use in electrical connection of an electric part, said structure comprising: a base member having a through-hole formed therein; a longitudinally compressible contact probe mounted in said through-hole of said base member so as to protrude upwardly therefrom when in an uncompressed state; an intermediate contact member having a first extreme end and a second extreme end, said first extreme end constituting a fulcrum and being rotatably supported by said base member such that said intermediate contact member is pivotable about said first extreme end between a rest position in which said second extreme end is in an upper position and a compressing position in which said second extreme end is in a lowered position; wherein said intermediate contact member includes a contact point at which said intermediate contact member contacts a protruding end of said compressible contact probe; and wherein said contact point is located at said second extreme end, such that said contact point is spaced apart from said fulcrum.
Claim 12
Dependent Claim
165 words
A structure for use in electrical connection of an electric part, said structure comprising: a base member having a through-hole formed therein; a longitudinally compressible contact probe mounted in said through-hole of said base member so as to protrude upwardly therefrom when in an uncompressed state; an intermediate contact member having a first extreme end and a second extreme end, said first extreme end constituting a fulcrum and being rotatably supported by said base member such that said intermediate contact member is pivotable about said first extreme end between a rest position in which said second extreme end is in an upper position and a compressing position in which said second extreme end is in a lowered position; wherein said intermediate contact member includes a contact point at which said intermediate contact member contacts a protruding end of said compressible contact probe; and wherein said contact point is located at said second extreme end, such that said contact point is spaced apart from said fulcrum.
Claim 13
Dependent Claim
32 words
A structure as recited in claim 10, wherein said fulcrum at said second extreme end of said intermediate contact member is disposed at a level below a level of said contact point.
Claim 14
Dependent Claim
59 words
A structure as recited in claim 10, wherein said intermediate contact member constitutes a means for longitudinally compressing said contact probe upon being pivoted from said rest position to said compressing position; and said contact probe is longitudinally resilient so as to constitute a means for restoring said intermediate contact member to said rest position from said compressing position.
Claim 15
Dependent Claim
20 words
A structure as recited in claim 10, wherein an entirety of said intermediate contact member is pivotable about said fulcrum.
Claim 16
Dependent Claim
28 words
A structure as recited in claim 10, wherein said intermediate contact member includes a stopper for setting an upper limit for pivotal movement of said intermediate contact member.
Claim 17
Dependent Claim
16 words
A structure as recited in claim 10, wherein said intermediate contact member comprises a spring member.
Claim 18
Dependent Claim
18 words
A structure as recited in claim 10, wherein said contact probe comprises a rod formed of entangled wires.
