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. The housing and the insert snap fit together by receipt of the contact separating rib in the through-passageway, between the contacts, with the latching tab closing the front opening and the resilient web hinge extending across the rebate. The latching tab has an upper catch portion which, in an undeformed position of the web hinge, protrudes above the upper wall of the housing in a rotation preventing position and a lower fingerpiece, depressible to resilient deform the web hinge and withdraw the catch portion toward the upper wall to a release position permitting rotation of the mounting head within the track cavity.
