Abstract: A connecting device for electrical junction boxes, including a sleeve member that can be inserted in a first hole of a first wall of a first box and in a second hole provided in a second wall of a second box to be joined to the first box. An annular gasket is fitted around the sleeve and is located between the two walls. The sleeve has a first end provided with a plate that is internal to the first box and a second end provided with an abutment means that engages the inner side of the second wall. The insertion of a wedge member, which is applied between the plate and the first wall, gradually moves the plate away from the inner side, pushing the walls against each other and compressing the gasket between them.

Abstract: A junction box particularly for lighting lines for tunnels includes a casing body provided with a cover; the casing body includes an electrical socket; a junction device inside the casing body connects the electrical socket to a pair of power supply wires of a power supply line that is affected by the junction box; the junction device includes one or more insulation displacement contacts; each insulation displacement contact engages a respective power supply wire without cutting it.

Abstract: A fuse holder, particularly for interlocked sockets and electrical apparatuses in general, includes a tray which is inserted in a seat and is adapted to accommodate a fuse. The tray is movable along a rectilinear path, having at least two positions: an active position, in which the fuse is active, and an extracted position, in which the fuse can be removed from the tray. The seat includes two elastic contact members which provide an electrical and mechanical connection of the fuse in the active position.

Abstract: A gasket for electric cables includes a main portion made of elastic material; a through hole that passes longitudinally through the main body and constitutes the seat of a cable to be insulated; a longitudinal slit passes through the body of the gasket and connects the through seat to the outside, allowing, by virtue of the elastic deformability of the material of the gasket, the insertion of the cable in the through seat.

Abstract: A fault signaling device, particularly for electrical apparatuses such as interlocked sockets and the like has an indicator constituted by a lamp (12) which is directly connected to the terminals of a fuse (5) whose blowing causes the lamp to lighted up. The lamp is mounted in the same supporting member (3) that contains the fuse.

Abstract: A snap-acting locking device, particularly for lids, doors and the like, has a slider adapted to be associated with a movable member, such as a lid, a door or the like, and to engage by snap-action a locking member provided on a body which the movable member that constitutes its lid, door or the like is articulated. The slider is a single body constituted by an actuation pushbutton provided with a stem, provided with a locking means, and by an elastic member, which is jointly connected to a free end of the stem; the locking means detachably engages the locking member provided in the body.

Abstract: A control assembly for interlocked sockets includes a rotary breaker which is actuated by a knob and is mounted on a supporting structure. The control assembly includes a visual indication means which has the purpose of highlighting the open/closed state of the rotary breaker as a consequence of rotations of the knob.

Abstract: An electrical outlet or plug includes a body, which encloses a connecting jack, which can be connected to a cable, and a grip element for clamping the cable. The body and grip element are provided with complementary features, which limit the axial unthreading movement of the latter in relation to the former and for preventing their disconnection once they have been connected. A locking nut is joined to the grip element axially, with the possibility of remaining joined to the said grip element, and through this, to the body when the nut is completely unscrewed and removed. Structure is also provided for preventing the unscrewing rotation of the nut once it has been screwed down.

Abstract: A steam-operated food cooking oven having a cooking cavity (2), a motor-driven fan (3) located at a rear side of the cooking cavity, and a partition wall (4) to distribute the flow of air generated by the fan into the cooking cavity. A back-chamber (5) accommodates the fan and is delimited on its front side by the partition wall (4) and, on its rear side, by the rear wall (6) of the oven. A tube (9) extends into the back chamber and terminates in a nozzle (10) that is received in an interstice between the rear wall and the fan. An appropriate temperature sensor (11), which is connected to a thermostat device (12), is inserted in the tube (9). A perforated disk is mounted over a motor shaft within the fan and allows air and steam within the back chamber to flow into the interstice and the nozzle therein to thereby communicate with the tube and temperature sensor therein.

Abstract: A food cooking oven having a vertically hinged access door 1 provided with an exterior glazing 2, and an inner door 3 arranged on the inner face of said door. The inner door is provided with a hinge 4 along the hinging edge of the access door 1 to the oven housing and is able to be turned with respect to the hinge to a position which is moved away and separated from said access door. The oven also includes a gutter 6 for collecting condensation water and other drippings. The gutter runs along the lower edge of the access door and is provided with a liquid shut-off means 7. A liquid collecting element 11 is arranged so as to protrude from the lower side 10 of the oven cavity opening perimeter, in a position lying underneath said liquid shut-off means, the latter being normally shut when the oven door is open, and adapted to close automatically when the door is being closed.
