Claim 6

A connector as claimed in claim 3 , wherein said first U-shaped portion comprises: a press-fitted portion press-fitted into said first space; a curved portion extending from said press-fitted portion; and an interference portion extending from the curved portion, said wall portion is formed with a convex portion which is protruded towards said first space to interfere with said interference portion.

Claim 7

A connector comprising: a plate-like insulator having a first and a second surface which confront each other in a first direction, and defining a plurality of spaces each extending between said first and said second surfaces, said insulator including a plurality of wall portions each dividing each of said spaces into a first space and a second space in a second direction crossing said first direction, said spaces being arranged in a third direction perpendicular to said first and said second directions; and a plurality of conductive contacts placed in said spaces, respectively, and held by said insulator, each of said contacts including: a retained portion retained in said first space utilizing said wall portion; and a spring portion extending from said retained portion, passing on the side of said first surface to bypass said wall portion and entering said second space, said spring portion including: a stopper portion approaching to confront said wall portion; and a contact portion protruding from said second surface to the exterior of said insulator.

Claim 8

A connector comprising: a plate-like insulator having a first and a second surface which confront each other in a first direction, and defining a plurality of spaces each extending between said first and said second surfaces, said insulator including a plurality of wall portions each dividing each of said spaces into a first space and a second space in a second direction crossing said first direction, said spaces being arranged in a third direction perpendicular to said first and said second directions; and a plurality of conductive contacts placed in said spaces, respectively, and held by said insulator, each of said contacts including: a retained portion retained in said first space utilizing said wall portion; and a spring portion extending from said retained portion, passing on the side of said first surface to bypass said wall portion and entering said second space, said spring portion including: a stopper portion approaching to confront said wall portion; and a contact portion protruding from said second surface to the exterior of said insulator.

Claim 9

A connector as claimed in claim 6 , wherein each of said contact includes a broadened tip extending from said contact portion to be located in said second space, said insulator having an escape groove for allowing said broadened tip.

Claim 10

A connector as claimed in claim 6 , wherein the contact portion of one of adjacent ones of said contacts is displaced from the contact portion of another of said adjacent ones in said second direction.

Claim 11

A connector as claimed in claim 6 , wherein said retained portion includes a first U-shaped portion located in said first space, said spring portion including: a second U-shaped portion extending from said first U-shaped portion so as to form substantially an S shape cooperatively with said first U-shaped portion; and a third U-shaped portion extending from said second U-shaped portion so as to form substantially an S shape cooperatively with said second U-shaped portion, said third U-shaped portion including said stopper portion and said contact portion.

Claim 12

A connector as claim 9 , wherein each of said contacts includes a terminal portion extending from said U-shaped portion to protrude from said first surface to the exterior of said insulator.

Claim 13

A connector as claimed 9 , in claim wherein said first U-shaped portion comprises: a press-fitted portion press-fitted into said first space; a curved portion extending from said press-fitted portion; and an interference portion extending from the curved portion, each of said wall portion being formed with a convex portion which is protruded towards said first space to interfere with said interference portion.

Claim 14

A connector comprising a contact and an insulator firmly retaining said contact, wherein said contact comprises: a first U-shaped portion; a second U-shaped portion; and a third U-shaped portion, said insulator has an insert portion into which said first U-shaped portion is inserted, said first U-shaped portion and said second U-shaped portion being provided inversely from each other so as to form substantially an S shape, said, third U-shaped portion extending from said second U-shaped portion to have a contact portion near an apex portion thereof for connection to a connection object, said first U-shaped portion having one end side firmly retained in said insert portion and the other end side contacting a first side of a wall portion of said insert portion, upon connection to said connection object, one end side of said second U-shaped portion, remote from said first U-shaped portion, being prevented from contacting a second side of said wall portion opposite to said first side, while upon connection to said connection object slantly relative to a connecting direction, said one end side of said second U-shaped portion contacts said second side of said wall portion, thereby to prevent an excessive displacement of said contact.

Claim 15

A connector comprising a contact and an insulator firmly retaining said contact, wherein said contact comprises: a first U-shaped portion; a second U-shaped portion; and a third U-shaped portion, said insulator has an insert portion into which said first U-shaped portion is inserted, said first U-shaped portion and said second U-shaped portion being provided inversely from each other so as to form substantially an S shape, said, third U-shaped portion extending from said second U-shaped portion to have a contact portion near an apex portion thereof for connection to a connection object, said first U-shaped portion having one end side firmly retained in said insert portion and the other end side contacting a first side of a wall portion of said insert portion, upon connection to said connection object, one end side of said second U-shaped portion, remote from said first U-shaped portion, being prevented from contacting a second side of said wall portion opposite to said first side, while upon connection to said connection object slantly relative to a connecting direction, said one end side of said second U-shaped portion contacts said second side of said wall portion, thereby to prevent an excessive displacement of said contact.
