METAL DETECTOR ASSEMBLY AND METHOD OF ASSEMBLING METAL DETECTOR

摘要

The invention provides a stable assembly of a metal detector by ensuring a tension free physical connection between a former and a case of the metal detector. The metal detector comprises a case with at least four closed sides and two openings, a non-conductive former having a pass-through aperture, and electromagnetic coils arranged on the former to produce an electromagnetic field within the former which is disturbed by a metallic body passing through the aperture. The former formed into a single piece and having a width equal to the inner width of the case, is inserted into the case from the front side of the case. The space between the former and the case is filled with a potting medium. The physical connection between the former and the case includes a protruding- recessing means which is strengthened by an adhesive.
