Abstract: A screw connection device for electric conductors, is provided having at least one screw-clamping piece assembly. A structure integral with the insulating body of the terminal, partially surrounds the screw head and has at least one heel. This heel is applicable against an inclined face of the clamp and is adapted so as to hold the screw-clamp assembly in position against removal along the axis of the screw and against tipping towards the conductor insertion side.

Abstract: An electronic card holding cell-like structure formed by the assembly of at least two modular electronic card supporting and protecting cells together, each of these modular cells having a blank and perpendicularly thereto, from its rear edge portion and its two side edge portions, respectively a bottom and two lateral sides, in which are formed two respective lateral slides parallel to the flat portion. The two longitudinal edge portions of each of the lateral sides of the modular cell being provided with respectively complementary fixing means so as to allow fixing of two adjacent modular cells.

Abstract: A modular cell for supporting and protecting electronic cards formed by a flat element or blank having two parallel lateral edge portions, a front edge portion and a rear edge portion and, extending perpendicularly to said blank, from its rear edge portion and from its two lateral edge portions, respectively a bottom and two lateral sides having card guide means forming two respective lateral slides parallel to the blank. This cell being further provided with fixing means for holding the card in position with respect to said blank, once the card has reached its position of use inside the cell, after sliding in said slides.

Abstract: A visual indicator lamp support is provided comprising an elongate insulating body having a front face and a rear face substantially perpendicular to its longitudinal dimension and forming, at its front face, jaws for insertion of the indicator lamp, a bearing surface inside said body cooperating with the rear face of the indicator lamp, holes through which the wires thereof extend formed through said body and means for securing to a printed circuit card, wherein said body forms a reference surface perpendicular to said rear face and joined thereto by a re-entrant surface adapted for freeing a portion of said wires and shaped so that bending back of said body from a first position in which its rear face is in abutment against the card and plays the role of spacer defining a pre-determined distance between said rear face of the indicator lamp and the surface of the printed circuit for soldering said wires to a second position in which said reference surface is in abutment against the card, results in causing p

Abstract: On at least one of two walls (16) (17) a terminal (7) housing (21) has a rib (44) respectively (45) that causes lateral distortion of a tubular housing (38) (39) which is part of a cover (3) so that the head (11) of a bolt of the terminal is gripped. This device, which is extremely simple to assemble, is recommended to make the terminal bolts so they cannot be lost and to hold them in an open position prior to wiring.

Abstract: Reversing contactor with mechanical locking. The casing (2) of the device includes a half-casing (3) to which are coupled two identical covers (70, 71), each of which closes one of two housings (9, 10), each of which receives the fixed and movable pieces of an electromagnet and the corresponding sets of contacts (49, 50). Such a contactor, which lends itself especially well to compact production, is used to change the direction of a motor with every guarantee of safety.

Abstract: An electro-magnetically controlled apparatus is provided having in a box an electro-magnet adapted to move an armature subjected to the force of a return spring developing an initial force, a contact holder associated with the armature and presenting side by side a plurality of pairs of housings each comprising a lower housing close to the armature, and an upper housing placed above, a plurality of mobile reversible bridge contacts, respectively placed in the respective housings and each receiving the action of a pressure spring which urges them against a cross piece separating two housings of a pair, these bridge contacts being adapted to cooperate each one with a pair of fixed reversible contacts disposed in the case so as to form one of the possible configurations of opening or closing switches placed in power or signalling circuits. The contact holder (9) comprises four pairs or superimposed housings (10.sub.U --11.sub.U, 10.sub.V --11.sub.V, 10.sub.W --11.sub.W, 10.sub.X --11.sub.X).

Abstract: A removable group of auxiliary switches is mounted on the upper surface (4) of the contactor housing by hinging means (28, 29) and resilient locking (32, 33) placed respectively in the area of the base (8) and of partitions (5) which separate the principal terminals (6). The group comprises two switches (make and break). Coupling in this manner makes it possible to increase the number of auxiliary switches without increasing the contactor's frontal or lateral congestion.

Abstract: An electrical apparatus which can be dismantled and is adapted to be fitted onto a fixed standard-shaped rail or section.The apparatus comprises a prism-shaped casing (50) having a rectangular opening (60) into which is accommodated a removable bottom (5) on the sides of which are provided means (25, 27) for fastening it to said casing and outer hooks (19, 20) adapted to cooperate with said shaped rail (2).Such an apparatus is particularly advantageous when its dimensions approximate the transverse dimensions of the rail or section, as it is the case when a small-size contactor or a relay is to be fitted into the casing.

Abstract: An electrical appliance in which flexible conductors connect the terminals of the plug to the terminals of the body, the plug being divided into elements capable of being separated in order to facilitate soldering and then reassembled on installation, the arrangement being advantageous for small devices such as relays.
