Abstract
Abstract A press-in contact includes a connection portion to be connected to a mating connector, a press-fitting portion to be fixed in a cylindrical through-hole of a printed circuit board by press-fitting, and a contact portion for introducing the press-in contact to the printed circuit board. The press-in contact further includes a positioning portion. The positioning portion has two plate-shaped pieces each having a surface to be urged by a jig for press-fitting operation and a connection part for connecting the plate-shaped pieces and the connection portion. The connection portion is formed in a substantially J-shape by bending, and center axes of the connection portion and the positioning portion are shifted from each other. As an alternative, the plate-shaped pieces are formed in a C-shape in cross-section, and center axes of the connection portion and the plate-shaped pieces of the positioning portion are shifted from each other. With this arrangement, the press-in contact can readily be press-fitted into the through-hole of the printed circuit board.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
126 words
A press-in contact comprising, a connection portion to be connected to a mating connector, a press-fitting portion to be fixed in a cylindrical through-hole of a printed circuit board by a press-fitting operation, and a contact portion for introducing the press-in contact into the through-hole of said printed circuit board, said press-in contact including a positioning portion with two plate-shaped pieces each having a surface to be urged by a jig for said press-fitting operation and a connection part for connecting said plate-shaped pieces to said connection portion, said connection portion being formed in a substantially J-shape, the center axes of said connection portion and said positioning portion being shifted from each other to prevent the connection portion from contacting the jig during said press-fitting operation.
Claim 2
Dependent Claim
126 words
A press-in contact comprising, a connection portion to be connected to a mating connector, a press-fitting portion to be fixed in a cylindrical through-hole of a printed circuit board by a press-fitting operation, and a contact portion for introducing the press-in contact into the through-hole of said printed circuit board, said press-in contact including a positioning portion with two plate-shaped pieces each having a surface to be urged by a jig for said press-fitting operation and a connection part for connecting said plate-shaped pieces to said connection portion, said connection portion being formed in a substantially J-shape, the center axes of said connection portion and said positioning portion being shifted from each other to prevent the connection portion from contacting the jig during said press-fitting operation.
Claim 3
Dependent Claim
129 words
A press-in contact comprising, a connection portion to be connected to a mating connector, a press-fitting portion to be fixed in a cylindrical through-hole of a printed circuit board by a press-fitting operation, and a contact portion for introducing the press-in contact into the through-hole of said printed circuit board, said press-in contact including a positioning portion with two plate-shaped pieces each having a surface to be urged by a jig for said press-fitting operation and a connection part for connecting said plate-shaped pieces to said connection portion, said plate-shaped pieces being formed in a C-shape, the center axes of said connection portion and said plate-shaped pieces of the positioning portion being shifted from each other to prevent the connection portion from contacting the jig during said press-fitting operation.
Claim 4
Dependent Claim
129 words
A press-in contact comprising, a connection portion to be connected to a mating connector, a press-fitting portion to be fixed in a cylindrical through-hole of a printed circuit board by a press-fitting operation, and a contact portion for introducing the press-in contact into the through-hole of said printed circuit board, said press-in contact including a positioning portion with two plate-shaped pieces each having a surface to be urged by a jig for said press-fitting operation and a connection part for connecting said plate-shaped pieces to said connection portion, said plate-shaped pieces being formed in a C-shape, the center axes of said connection portion and said plate-shaped pieces of the positioning portion being shifted from each other to prevent the connection portion from contacting the jig during said press-fitting operation.
Claim 5
Dependent Claim
38 words
The press-in contact as set forth in claim 1 or 2, wherein the center axes of said connecting portion and said plate-shaped pieces of the positioning portion are shifted from each other by 0.5 mm to 1.0 mm.
