Abstract
A universal lattice assembly for use in a magnetic-type electronic article surveillance system is disclosed which comprises a frame formed of two identical molded plastic half-shells, a metal chassis within which specific electronic sub-assemblies may be positioned and a coil assembly including a field-producing coil and a detector coil. The frame includes a substantially continuous series of tabs and notches which are positioned to be inter-connected as the half-shells are pressed together, the resulting assembly becoming dimensionally rigid, thus firmly anchoring a coil assembly in place, preventing any relative movement as the assembled unit may be jostled in operation.
