An electrical device such as a panel meter with a body including an abutment, is inserted through an opening in a panel with the abutment on one side of the panel, and is secured to the panel with a nut plate on the other side of the panel. The body of the meter has plural teeth, discontinuous around the periphery of the body and the teeth extend from opposite sides of the body. The nut plate has an opening with flexible sides to enable snapping the nut plate over the body and teeth to a position abutting the panel to clamp the meter to the panel. Portions of the opening in the nut plate are enlarged so that moving the nut plate to a position in which the body teeth are adjacent the enlarged portions of the opening releases the nut to permit immediate and rapid removal of the meter from the panel. There are several teeth at each side of the body to enable mounting and securing the meter in panels of substantially different thicknesses. Spacers on a front face of the nut plate permit the resilient sides of the nut plate to be snapped over the meter body teeth close to the panel while spacing the nut plate from the panel so the nut plate exerts a bias or pull on the meter which maintains the meter firmly in position on the panel, irrespective of the thickness of the panel.
An arrangement for mounting a meter on a panel having an opening comprising, in combination a meter assembly including a casing having a face plate and a body connected to said face plate and projecting rearwardly therefrom;
A mounting arrangement for mounting an electrical device such as a meter on a panel having an opening comprising, in combination, an electrical device having a body extending through the panel opening, abutment means on the body for positioning the body with respect to one face of the panel, plural teeth on said body, said teeth being discontinuous about the body, quick connect ratchet nut means on the body on the opposite side of the panel from said abutment means for clamping the panel between the abutment means and the nut means to secure the device to the panel, said nut means comprising a thin nut having an opening with first narrow flexible side portions dimensioned to snap over and engage selected teeth of said body, so that the nut means can be moved along a straight line, in ratchet fashion to a clamping position with said panel and second side portions dimensioned to clear said teeth, said nut being movable from said clamping position in which the first portions engage said teeth to secure the device to the panel, to a released position in which the second side portions are adjacent said teeth and the first side portions are disengaged from the teeth.
A mounting arrangement for mounting an electrical device such as a meter on a panel having an opening comprising, in combination, an electrical device having a body extending through the panel opening, abutment means on the body for positioning the body with respect to one face of the panel, plural teeth on said body, said teeth being discontinuous about the body, quick connect nut means on said body engaging selected ones of said teeth for clamping the panel between the abutment means and the nut means, said nut means including flexible side portions engaging said selected teeth, said flexible side portions permitting snapping the nut means along and over the teeth in a straight line to clamp the electrical device to the panel without rotating the nut means, said nut means having an opening defined in part by said flexible portions and in part by additional portions of the nut means, the additional portions having a space therebetween greater than the distance between the flexible portions to enable disengaging the nut means from the teeth by moving the nut means to a position in which the additional portions are in opposed relation to said teeth.
