Definitions
- a contactor is a switching device for power electronics, comprising a moving part moved by a mechanical actuator to establish and break an electrical current.
- the economizer contact is closed at rest by the action of the blade 8 which urges the contact pad 9 towards the fixed contact, and opens when the stop 10 comes to rest against the blade 8 in the high position of the mobile part 3 .
- a cover is generally assembled around the assembly formed by the blade and the economizer contact, in order to protect it from the outside.
- the passage hole of the stop in the electrical card is much larger than the circumference of said stop, to accept significant positioning tolerances of the economizer contact stop.
- the economizer contact is adapted to switch the actuation current of the contactor to a holding coil when the moving part is at the end of its stroke and the economizer contact is closed.
- the fixed part may comprise an electrical card on which the blade is mounted, by a first end of the blade, and a fixed contact arranged at a second end of the blade, the orifice being defined in the electrical card, in look of the blade.
- Such a characteristic makes it possible to have a freely movable stop in the transverse plane, to easily adjust the position of the stop dynamically.
- the support may comprise a recess receiving the flat part, the auxiliary blade defining an opening facing the recess, the stop extending through the opening towards the passage orifice.
- the stop may comprise a threaded rod extending in the main direction and a head mounted on the rod and adjustable in height relative to the rod in the main direction.
- the ring may have a circular external section having a first radius, the passage orifice having a circular internal section having a second radius, the first radius being less than the second radius of a clearance adapted to prevent the passage of dust.
- the stop may include means for blocking the movement of the head relative to the rod.
- the electrical contactor comprises a fixed part 2 comprising an electrical card 6 and a mobile part 3 comprising an auxiliary blade 5, as described previously.
- the mobile part 3 can be moved in translation in a main direction Z under the action of an actuating coil (not visible in Figure 2), so as to bring the electrical card 6 and the auxiliary blade 5 closer together.
- an actuating coil not visible in Figure 2
- the electrical card 6 and the auxiliary blade 5 extend substantially parallel to each other, perpendicular to the main direction Z.
- the electrical card 6 comprises a support 7 carrying an elastic blade 8, said blade 8 being fixed to the support 7 by a first end and carrying a contact pad 9 at its free end.
- the support 16 is a plate fixed by crimping under the auxiliary blade 5, supported in the main direction Z, for example by two fixing members 25 engaged in corresponding fixing orifices 26 of the support 16 and the auxiliary blade 5.
- the support 16 can be fixed to the auxiliary blade 5 by any other known manner, for example by bolting, screwing, welding, etc.
- the flat part 21 is placed in the recess 27 and held in the main direction Z between the intermediate card 5 and the support 16.
- Figure 4 represents, in section in the transverse plane XY, the flat portion 21 of the support and the recess.
- the flat portion 21 and the recess both have elongated shapes in this plane XY in the same transverse direction X, which is for example the direction of alignment of the fixing orifices 26 by crimping.
