Connector suitable for connecting a pair of circuit boards arranged in parallel

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.

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.

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.
