ABSTRACT:
An electrical connection element is of an integral construction formed by blanking and bending (i.e., metal sheet working) a single metal base plate. More specifically, the electrical connection element includes a clamping portion formed at one longitudinal end for compressively clamping an end portion of a connection wire, a resilient connecting portion formed at the other end portion by folding the metal base plate twice, an outer wall portion surrounding the resilient connecting portion, and a pair of flexure prevention pieces which are formed on the metal base plate, and are provided respectively at opposite side walls 14a and 14b of the outer wall portion. A distal end of each of the flexure prevention pieces is slanting at an angle corresponding to the angle of inclination of the resilient connecting portion deformed to a predetermined degree. For connecting a male terminal, it is inserted in a predetermined direction, so that the resilient connecting portion is resiliently deformed to be brought into face-to-face contact with the slanting distal ends of the flexure prevention pieces. Therefore, even if an excessive external force is applied, the resilient connecting portion will not be plastically deformed by the corners of the distal ends of the flexure prevention pieces.
