Embodiment Construction

[0045] refer to figure 1 , the housing 1 is arcuate in shape with an inverted U-shaped through hole 2 and a rod 3 enclosing a part of a magnetic armature (not shown). The housing 1 is completely closed, which means that the inner face delimiting the U-shape is the closed wall of the housing 1 , as is the outer side. The upper outer side 4 also includes a single opening formed in the housing 1 , an orifice 5 allowing the passage of a rod 6 of an actuator, the mechanical power of which can for example actuate a mechanical lock of a differential electric device.

[0046] The coil associated with the actuator of the invention is wound around the rod 3 in this configuration, for example after having been placed on the coil support, which is placed on the figure 2 is shown very schematically.

[0047]Such a coil support 7 is composed of two parts 8 , 8 ′ which, in the present case formed symmetrically according to one possible configuration, can be assembled on either side of the...

Abstract

The invention relates to an electromagnetic actuator comprising a magnetic circuit consisting of a stationary magnetic armature and a blade, said blade being movable in opposition to a spring and capable of moving a mechanical actuating member, and an induction coil arranged about an arm of the armature, the assembly being inserted into a housing from which the mechanical member extends. The housing comprises a through-slot located inside a magnetic circuit, in which through-slot the coil is wound once the housing is closed.

Description

technical field [0001] The invention relates to an electromagnetic actuator of the differential relay type, and to the actuator itself and to a method for assembling such a device. The actuator according to the invention is a highly sensitive device which is used in particular in the field of differential protection when considered independently of the voltage. Background technique [0002] In this context, actuators or differential relays used in industry or service are of different types in order to be able to meet current standards (differential products of type A, AC, G, S, etc.). However, their geometry is the same, ie the parts constituting them are the same, with the exception of the coils, the number of turns and the wire sections being adjusted for each relay type as described above. In fact, there are at least two different types of relays that meet different practical needs. [0003] These types of electromagnetic actuators typically include: [0004] - a fixed...
