Abstract: An electrical connector is adapted for mounting in an aperture in a panel. A housing has sidewalls bounding an insertion end of the housing insertable into the aperture. A bridge is secured at opposite ends to one of the sidewalls with an intermediate portion and a panel latch being freely flexible relative to the housing. At least one of the opposite ends of the bridge includes a pair of redundant supporting arms. A yieldable anti-vibration arm projects from another of the sidewalls and is mounted to the housing by a pair of redundant support arms. A polarizing rib projects from the housing, and a panel abutment stop is formed integral with the polarizing rib on a radius.
