ABSTRACT:
A locating ring for positioning and supporting an electric coil within a mold for encapsulation of the coil. The locating ring comprises an annular body defining a central axis and a plurality of tabs extending generally axially from the annular body. The annular is adapted to insulate the coil from a steel shell. The tabs are adapted to position the coil within the mold. In a preferred embodiment, the tabs include a recess along a portion of the radially inner face thereof which receives the encapsulating material prevents the separation of the tabs therefrom. In an alternate embodiment, a portion of the sidewalls of each tab are tapered outwardly from the inner face to the outer face thereof. In another aspect of the invention, the body of the locating ring includes a plurality of circumferentially spaced openings extending axially therethrough which provide a number of routes by which air may be vented during the molding operation.
