摘要：
Rectangular bus bars (3, 5, 7) alternatively engaged in either of a pair of crossed slots (33, 35) in a support block (23) secured in a panel board (11) are locked in place by a locking device (43) incorporated in a cylindrical terminal portion (15) of each bus bar (3, 5, 7). The locking device (43) includes an expandable ring (45) seated in a circumferential groove (47) in the cylindrical terminal portion (15). A pair of actuating pins (57, 59) are urged radially outward in diametrically opposed bores (53, 55) to wedge the expandable ring (45) against the support block (23), by a tapered screw (61) threaded into a central longitudinal bore (51) in the terminal portion (15) of the bus bar (3, 5, 7).
