Abstract
Abstract The electrical connector in accordance with the present invention may be distributed with the shield frame thereof temporarily mounted on the connector body thereof. While the shield frame is temporarily mounted, a portion of the connector body is restrained between engagement pawls or projections formed on the shield frame. While the shield frame is temporarily mounted, the shield frame is backed up by the connector body, thus preventing the shield frame from being readily deformed. When the shield frame is pushed to the connector body with a force sufficient to resiliently deform the engagement pawls on the shield frame, the shield frame may be moved from a temporary-fitting position to a final-fitting position. At the final-fitting position, the engagement pawls of the shield frame are engaged with final-fitting engagement portions of the connector body by the restoring force of contact pieces which are formed at the lower end of the shield frame and which are pressingly contacted with a member on which the electrical connector is mounted.
