Abstract

Abstract An object of the present invention resides in providing a connector which assures that clearance between an engagement projection of a flexible engagement piece projecting from the inner wall of each terminal accommodating chamber of a connector housing and an engagement hole of a terminal is minimized, and moreover, each terminal is properly inserted into the corresponding terminal accommodating chamber with a higher intensity of engaging force. According to the present invention, a connector includes a plurality of terminals each of which one end serves as an electrical contact portion having an engagement hole formed on a base plate and of which other end serves as a cable connecting portion. In addition, the connector includes a connector housing having a plurality of terminal accommodating chambers formed therein. A flexible engagement piece having an engagement projection formed at the foremost end thereof is projected from each terminal accommodating chamber, and the engagement projection serves as engaging means for allowing the engagement hole of the terminal to be engaged with the engagement projection. An upper surface is formed on the engagement projection while slantwise downwardly extending toward the cable connecting portion of the terminal. In addition, tapered portions are formed along ridge lines where the upper surface intersects both side surfaces.
