Patent ID: 6986670

Claim:
A low-profile connector constituted by a header and a socket, which are respectively mounted on circuit boards for connecting electric circuit formed on the circuit boards, wherein the header comprises a header body made of resin molding, and a plurality of posts made of a conductive metal thin plate and provided at a predetermined pitch on a peripheral wall of the header body; the socket comprises a socket body made of resin molding and a plurality of contacts made of a conductive metal thin plate and provide at the predetermined pitch in a guide grooves on a peripheral wall of the socket body, which are to be contacted with the posts provided on the header; each post is inserted into the header body and comprises a first contact portion appeared on an outer face of the peripheral wall of the header body, a second contact portion appeared on an inner face of the peripheral wall, a ceil portion formed between the first contact portion and the second contact portion and overstriding the peripheral wall, and a soldering terminal formed on an end of the second contact portion by bending substantially at right angle, at which the post is soldered on a circuit pattern of a circuit board; and each contact comprises a plate spring portion, a fitting portion at which the contact is held on the socket body and a terminal portion to be soldered on a circuit pattern on a circuit board, which are integrally formed from a front end to a rear end of the contact; the fitting portion has a first contact portion disposed along an inner face of a peripheral wall of the socket body and to be contacted with the first contact portion of the post of the header, and a ceil portion overstriding the peripheral wall and an arm portion substantially parallel to the first contact portion; the plate spring portion has a lateral portion, a first slanted portion, a curved portion, a second slanted portion, and a doglegged second contact portion to be contacted with the second contact portion of the post of the header; the lateral portion is formed by bending substantially at right angle for protruding inwardly from a lower end of the first contact portion of the fitting portion; the first slanted portion is formed by bending at a predetermined angle with respect to the lateral portion from a top end thereof; the curved portion is formed by bending from the top end of the first slanted portion so as to be turned back substantially in the opposite direction; the second slanted portion is formed as an elongation of the fourth curved portion; and the second contact portion is formed for incurving an elongation of the second slanted portion.
