Claim 1
Independent Claim
200 words
A contact for contacting with a pin terminal projecting vertically from a lower surface of an IC body, said contact comprising: first and second contact pieces extending vertically and respectively having plate surfaces opposed to one another so as to receive the pin terminal therebetween under pressure; wherein upper end portions of said first and second contact pieces are bent forwardly to form forwardly-bent pieces, respectively; wherein upper edge portions of said forwardly-bent pieces are respectively bent backwardly to form backwardly-bent upper pieces; wherein inner curved-surfaces of said backwardly-bent upper pieces respectively serve as pressure contact surfaces to contact with the pin terminal; wherein side edge portions of said forwardly-bent pieces on a pin terminal introduction side thereof are respectively bent backwardly to form backwardly-bent side pieces continuous with said backwardly-bent upper pieces; wherein inner curved-surfaces of said backwardly-bent side pieces are respectively continuous with said inner curved-surfaces of said backwardly-bent upper pieces; and wherein inner curved surfaces of upper ends of said backwardly-bent side pieces respectively serve as pressure contact surfaces to contact with the pin terminal at an early stage of introduction of the pin terminal in an introduction direction in between said first and second contact pieces.
Claim 2
Dependent Claim
200 words
A contact for contacting with a pin terminal projecting vertically from a lower surface of an IC body, said contact comprising: first and second contact pieces extending vertically and respectively having plate surfaces opposed to one another so as to receive the pin terminal therebetween under pressure; wherein upper end portions of said first and second contact pieces are bent forwardly to form forwardly-bent pieces, respectively; wherein upper edge portions of said forwardly-bent pieces are respectively bent backwardly to form backwardly-bent upper pieces; wherein inner curved-surfaces of said backwardly-bent upper pieces respectively serve as pressure contact surfaces to contact with the pin terminal; wherein side edge portions of said forwardly-bent pieces on a pin terminal introduction side thereof are respectively bent backwardly to form backwardly-bent side pieces continuous with said backwardly-bent upper pieces; wherein inner curved-surfaces of said backwardly-bent side pieces are respectively continuous with said inner curved-surfaces of said backwardly-bent upper pieces; and wherein inner curved surfaces of upper ends of said backwardly-bent side pieces respectively serve as pressure contact surfaces to contact with the pin terminal at an early stage of introduction of the pin terminal in an introduction direction in between said first and second contact pieces.
Claim 3
Dependent Claim
34 words
A contact as recited in claim 1, further comprising a third contact piece extending vertically and having a plate surface disposed generally perpendicular to said plate surfaces of said first and second contact pieces.
Claim 4
Dependent Claim
23 words
A contact as recited in claim 3, wherein said first, second and third contact pieces are connected together at lower ends thereof, respectively.
Claim 5
Dependent Claim
24 words
A contact as recited in claim 3, further comprising a male terminal extending downwardly from a lower edge portion of said third contact piece.
Claim 6
Dependent Claim
22 words
A contact as recited in claim 1, wherein said first and second contact pieces are connected together at lower ends thereof, respectively.
Claim 7
Dependent Claim
18 words
A contact as recited in claim 1, wherein side edges of said forwardly-bent pieces constitute inclination surfaces, respectively.
Claim 8
Dependent Claim
20 words
A contact as recited in claim 6, wherein said inclination surfaces are offset from one another in the introduction direction.
