Abstract: The male connector used in an electrical junction box employs a guide rib which is disposed perpendicular to the long side of an enclosing rib which encircles the male tab opening. The guide rib, positioned on both long sides of the enclosing rib, guides the tab into the male tab opening in order to prevent damage which occurs when there is misalignment of the tab with the male tab opening. In order to further assist in the realignment of the tab with the male tab opening, the surfaces of the enclosing rib and the guiding rib are sloped towards the male tab opening to allow the tab to be guided into the male tab opening during assembly of the junction box.
