  • Patent number: 6210177
    Abstract: An electrical connector comprises an insulative housing and a plurality of terminals. The insulative housing includes a central portion, a pair of side walls and a pair of lateral walls. The central portion defines a plurality of passageways therethrough for receiving corresponding terminals therein. Each terminal comprises a fixing portion, a contacting portion, a slanting portion and a tail portion. The contacting portion is formed at the top end for electrically contacting with a mating connector. The slanting portion slantways extends from the fixing portion with an obtuse angle. A tail portion is formed at the end of the slanting portion. A soldering portion of each terminal is folded at a same plane before soldering on a circuit board. Therefore, after the terminals are assembled to the insulative housing, the soldering portions of corresponding terminals can be arranged with a proper planarity and the quality of solder process is also improved.
