摘要： An electrical breaking module includes a non-magnetic, electrically insulating casing housing, a fixed contact and a movable contact defining between them a breaking zone in which an electric arc extends at its origin when the electrical circuit is opened. A magnetic blow-out device is provided with at least one magnetic field source arranged in a breaking chamber, opposite the breaking zone to move and stretch the electric arc in a direction substantially perpendicular to the breaking plane towards the housing. The magnetic blow-out device also includes a non-magnetic, electrically insulating deflector, arranged in the breaking chamber to occupy most of the space between the breaking zone and the casing, so as to create at least one arc confinement zone, in which the electric arc when magnetically blown is deflected and constrained to promote its cooling and extinction.

摘要： A fuse device comprising a housing, at least two connection lugs, a connecting element between the connection lugs, and an actuator. The actuator moves the connecting element from a closed position, in which it connects the connection lugs, to an open position, in which it is disconnected from at least one of the connection tabs. A particularly well-conducting connection between the connection lugs and the connecting element, which can nevertheless be easily disconnected by the actuator, is achieved by the connecting element being interference-fitted between the connection lugs.

摘要： A disconnector having a stack of modular contact boxes surmounted by a snap-action switch box, each modular contact box including a rotary contact and two fixed contacts which are accessible from the outside. The switch box further includes a driven indexing element which is rotatably associated with a spindle loading support and at least one spring connected between the two in order to load them elastically with respect to each other following a mutual rotation about the central axis. The disconnector has a single actuation rod which passes through all the modular contact boxes coaxially to the central axis and is fixed in rotation to all the rotary contacts.

摘要： A plug-in circuit breaker that includes a housing, an operating mechanism and a button mechanism which has a closing position and an opening position. The circuit breaker further includes a locking member and a linkage member arranged inside the housing. The linkage member is provided with an abutting protruding stand. The locking member is provided with a locking protruding stand. When the button mechanism is in the closing position, the abutting protruding stand of the linkage member extends out of the housing and is limited by the button mechanism at an extension position, so that it cannot retract into the housing. When the button mechanism is in the opening position, the linkage member retracts into the housing, the locking protruding stand of the locking member extends out of the housing, and the locking protruding stand of the locking member can be pushed back into the housing.

摘要： The utility model discloses an automatic balance apparatus with a double-moving-contact spring leaf in a socket, which may ensure that two moving contacts are in good contact with corresponding stationary contacts. The automatic balance apparatus includes a lifting slide block, where the lifting slide block is provided with a lifting base below the spring leaf, a balance warped plate corresponding to an arrangement direction of moving contacts is movably disposed in the lifting base, and upward protruding portions are respectively disposed on two sides of the top surface of the balance warped plate. The utility model is particularly applicable to various ground fault circuit interrupters (GFCIs) and arc fault circuit interrupters (AFCIs).

摘要： An electrical connection device (200) connected between a main body and a draw-out device of an electrical appliance having a draw-out structure. The electrical connection device comprises: a draw-out device connection assembly (202) being fixed on the draw-out device and electrically connected to inlet and outlet ends of the draw-out device; a main body connection assembly (204) including contact pieces (241, 441, 541) with a clamping mechanism, wherein the clamping mechanism makes the contact pieces (241, 441, 541) close to and clamp main body busbars (208, 408, 508); and a flexible assembly (206) connecting the draw-out device connection assembly (202) and the main body connection assembly (204) to form a conductive path. The contact pieces (241, 441, 541) of the main body connection assembly (204) are offset by adapting to the position deviation of the main body busbars (208, 408, 508), so that the contact pieces (241, 441, 541) close to and clamp the main body busbars (208, 408, 508), and the flexible assembly (206) absorbs the offset of the contact pieces (241, 441, 541) by its own deformation, the offset is not transferred to the draw-out device connection assembly (202). It is further disclosed a linked electrical connection assembly formed by the described electrical connection devices (200) as well as an electrical appliance using the described electrical connection devices (200) or the electrical connection assembly.

摘要： A lever input device includes: a lever which is tiltable in a first direction orthogonal to an axis of the lever about the axis due to an operation by a user; a swing arm which engages with the lever and swings along with the tilting of the lever in the first direction and amplifies a displacement amount of the lever at the time of tilting; and a magnet body mounted on the swing arm, wherein the swing arm is elongated along a second direction which is a direction along the axis, is configured such that distance (D13) between a swing fulcrum and a mounting portion of the magnet body becomes larger than distance (D12) between the swing fulcrum of the swing arm and an engaging portion of the swing arm with the lever.
