摘要： A ring maintains a circular daughtercard (32) plugged into a mothercard (30) and includes structure for removing the daughtercard from the mothercard. The ring includes: an inner vertical threading to be screwed on an external threading fixed to the mothercard (30), and a bottom portion having a cylindric recess for accommodating the daughtercard (32), the recess being coaxial to the threadings and having a depth substantially equal to the thickness of the daughtercard (32). The ring also includes at its bottom portion a plurality of vertical traversing rods (42) distributed about the recess, each having, at one end, an eccentric portion for releasing the daughtercard (44), and, at the other end, a roller for manipulating the rod and the eccentric portion. Each rod is manually operable by the roller to be brought to a first position, where its eccentric portion partially covers the recess while maintaining the daughtercard (32) without pressure in the recess, or to a second position where its eccentric portion does not maintain the daughtercard in the recess.

摘要： A pole-unit of a gas-blast electrical circuit breaker comprises a tranverse partition made of injected insulating plastic material which at the same time performs guiding of the movable contact which passes through it. The injected material part bears an O-ring ensuring tightness with the casing and a one-way check valve of gas flow orifices arranged in the transverse partition. The gas-blast piston securedly united to the movable contact is also made of injected material and it comprises housing and clipping means of the puffer nozzle securedly fixed to the piston. A scraper seal in the form of a split segment is housed in a circumferential groove arranged in the injected part of the piston. The electrical connection between the movable contact rod and a flexible current supply insert is achieved by a braided strip extending in the form of a half-loop in a transverse plane to the pole-unit.
