Abstract:
Fuse-holding modular structure comprising:a flat rectangular frame (1), molded in thermoplastic material, with two longer opposite side walls (4, 5) and two shorter opposite side walls (2, 3) perpendicular to the plane of the frame and forming a housing space for a plurality of modules, said longer side walls being equipped inside with a plurality of plates (51), parallel to and distanced from said longer side walls, fixedly connected to said longer side walls by a continuous upper edge (52) of said longer side walls and by a plurality of ribs perpendicular to the plane of the frame, in each of said plates, (51) being formed, in its median section, an elastic tab (55) with a retaining tooth (56), each of said plates forming a rail extending perpendicular to the plane of the frame, for the sliding attachment with corresponding tenons of a module, and a plurality of fuse-holding modules (6) with a parallelepiped rectangle-shaped body, in plastic material, with an upper and lower face, two longer opposite side walls (9, 10) and two shorter opposite side walls (7, 8), the distance between said shorter side wals being equal to the distance between two opposite plates (51) of said longer side walls (4, 5) of the frame (1), said modules (6) being equipped, each of said shorter side walls (7, 8) with: a pair of tenons (42, 44; 43, 45), extending between the lower and upper face of the module and slidably engaged with one of said rails formed by said plates (51), shoulder means (46) which define, by interference with said frame (1), the relative positioning between module and frame in the direction perpendicular to the plane of the frame, and a lacking tooth (50) which ensures, by interference with said retaining tooth (56), the removable locking of the module in the frame.
