  • Patent number: 5588182
    Abstract: A durable, economical, and aesthetically pleasing terminal enclosure (2) for housing standardized terminal blocks (50). The terminal enclosure (2) includes a base section (30) formed as an open-faced trough with integral perpendicular end panels (24, 34). The terminal enclosure (2) also has a pair of gull-wing doors (10, 20) which may be closed to cover the base section (30). The doors (10, 20) are formed with a curvature to provide a continuous arching cover over the base section (30), and a plurality of legs (12-1 . . . 5, 22-1 . . . 5) is angled downwardly and inwardly from each door for pivotal attachment to the underside of the base section (30). The combined curvature of the legs (12-1 . . . 5, 22-1 . . . 5) and the doors (10, 20) allows opening without a need for frontal clearance. In addition, the legs (12-1 . . . 5, 22-1 . . . 5) are pivoted to the base section (30) in such a way that they may be locked in the full-open position, thereby freeing both hands for servicing.
