ABSTRACT:
An insulated wire subjected to mechanical vibrations, such as a supply lead or an electromagnetic coil of an automobile horn or other sound generator, is partly received in a groove of a conductive connector plate overlain by a conductive or nonconductive retaining plate. The groove has a width and a depth substantially corresponding to the diameter of the insulated wire but is constricted near its bottom, over part of its length, by one or two inwardly projecting ledges with sharp edges cutting into the insulation and contacting the bare wire which deforms into the narrowed groove portion, the cross-sectional area of the groove in its constricted part being substantially equal to that of the insulated wire.
