Abstract: A device for inserting wires and/or pipes in a tubular, flexible sheath includes a sleeve (11), with a split (111) made therealong. The sleeve (11) is encircled by a cylindrical tubular body (21) also having made therealong a relative split (211). The sleeve (11) can turn inside this cylindrical tubular body (21), so as to define two working positions, first (H1) and second (H2). In the first working position (H1), the split (111) of the sleeve (11) corresponds to the split (211) of the tubular body (21), so that the wires can be inserted into the device. In the second working position (H2), the split (211) of the tubular body (21) is closed by the sleeve (11), so as to block the wires inside the device. A rounded, wedge-shaped member (23) rising over the cylindrical tubular body (21) is to be slidably fitted in the flexible sheath (F). The profile of the member (23) allows to open the edges of the elements (3) of the sheath, so as to insert the wires thereinside.

Abstract: In a support device for printed circuit broads with a support structure, equipped with at least one board guiding groove, a locking group has the task of locking detachably the boards. The support structure has at least one transversal cutting which crosses the groove and cooperates with the locking group. The locking group includes a guiding element which slides inside a relative guiding seat. One end of the guiding element is connected to a plate provided with at least one locking element which is introduced inside the transversal cutting for locking the board.

Abstract: A fuse block, particularly for printed circuits, consists of a small block of insulating material, having a "U" shape, to whose wings are locked two equal terminals, provided at the bottom with a coupling for printed circuit and at the top with two prongs designed to receive a head of a fuse, restrained by a small frame. From the small frame extend two wings shaped in such a way as to allow the easy insertion between themselves of the fuse and the subsequent elastic restraint of the fuse.

Abstract: A grating is fastened to the housing of a computer by threaded nuts and screws, having a truncated-cone head and passing through holes made on the grating, on the housing, and on the frame of an aspirator, as well as through truncated-cone shaped bushings, which are provided with extensions turned towards the center of the grating, so to remain below a portion of a metal net placed over the screws and kept in place by a cover snap-locked to the grating, so that the net is electrically connected with the housing.If the frame of the aspirator is made of plastic material, then an electric connector, is linked to one of the screw or nut, with a conductor connector with the housing.
