Abstract: An adaptor box for mounting a fixture to a low voltage track having a housing containing contacts with one of their ends formed with female contact portions which are arranged on above the other in the housing to provide a common mating axis in the housing connection to a male coax connector of the fixture and other ends forming feet protruding from a mounting head of the housing for connection to respective busses of the low voltage track. Contact separating and locating protuberances are molded on the interior of the housing and an insert molded with additional contact locating and separating protuberances is assembled through a front opening in the housing.

Abstract: An adaptor box for mounting a fixture to a low voltage lighting track having a channel-form cavity retaining wire busses has a one piece, molded housing with opposite side walls joined by upper, lower and rear walls providing a front opening cavity. A mounting head upstands from the upper wall and is formed with opposed mounting ears. A contact receiving through-passageway having a front, contact insertion opening extends from the housing cavity, vertically through the mounting head between the ears, the upper wall being recessed so that the housing is open at a front and at a top, adjacent the front. A one-piece molded insert has a contact separating rib and a releasable, rotation preventing latching tab portion connected together by a transverse, resilient web hinge. A pair of contacts terminating fixture wires extend through the passageway with free ends exposed for electrical connection to the busses.
