Definitions
- the present invention relates generally the adaptation interfaces to be inserted between a switch differential and one or more electrical auxiliaries normally designed to be combined with circuit breakers.
- electrical auxiliaries is meant here, so usual, electrical devices intended to ensure additional functions, such as, for example, triggering, switching and / or signaling.
- the present invention relates more particularly to the case where that at least of the electrical auxiliaries which is directly attached to the adaptation interface is an auxiliary electrical transmitter, i.e. an electrical device which, independently, and like a switch differential, is also likely to be, in given conditions, the subject of a triggering process.
- an auxiliary electrical transmitter i.e. an electrical device which, independently, and like a switch differential
- Another of the functions of the adaptation interface is then to pass, from this electrical auxiliary to the differential switch, the tripping order corresponding.
- the interface adapter includes, in a housing, to ensure the whole of its functions, an input lever, which, pivotally mounted on the housing, at a first fixed point thereof, is capable of being actuated by the differential switch, an input and output lever, which, pivotally mounted on the housing, at a second fixed point therefrom away from first, can be operated by an auxiliary electric or actuate it, an intermediate lever, which, coupled to the input lever by a buttonhole mounting, is articulated in scissors to the entry and exit lever of so as to bring him with him when he is himself driven by the input lever, and an output lever, which, pivotally mounted on the housing, at a third fixed point of this one, is likely to command in triggering the differential switch in response to an action of the electrical auxiliary on the input lever, and which, for doing this is under the control of the intermediate lever
- this adaptation interface is devoid of any autonomous source energy, the energy it needs to transmit from a electrical appliance to another a trip order him being supplied by that of these electrical devices which, acting as a transmitting electrical device, is at the origin of this trigger order, both in case this device electric transmitter is the differential switch that in the case where it is the associated electrical auxiliary.
- a four-pole differential switch may, for its triggering, require energy relatively important, that a simple electrical auxiliary does then not sufficient to provide.
- the present invention generally has for subject a provision to overcome this shortcoming.

- the input lever 20 drives, also, by pivot 35, counterclockwise, and such that shown diagrammatically by an arrow F3 in FIG. 6, the pusher of resetting 85, the release lever 24, thus released, turns, counterclockwise, under the demand of the means elastic 59, around the third fixed point A3 of the housing 16, as shown by an arrow F4 in Figure 6, which leads its hook 71 to come into engagement with the hook 70 of the retaining lever 60, after absorption of the initial guard between these.
- fork 93 of the lever tilting 92 comes to bear on the blade 90 of the means switching 89 and requests it to tilt in the direction of that of the fixed contacts 91 which is furthest from the joystick 15.
- the input lever 20 can continue to rotate, without interference on the position of the tilting 92.
- the handle 15 of the adaptation interface 10 duly driven by the handle 13 of the differential switch 11, has rotated counterclockwise around its axis of rotation, as shown in Figures 5, 6 and 7.
- the electrical auxiliaries 12 are themselves engaged, the input and output lever 21, which follows the movement corresponding engagement, remaining in engagement, with play, with the relevant member of the electrical auxiliary 12 immediately adjacent, following the mechanical link L3.
- the input and output lever 21 causes, by the mechanical link L3, the triggering of the electrical auxiliary 12 immediately adjacent, and, by way consequently, that of the following electrical auxiliary 12, and so on, step by step, an auxiliary electric 12 to another, when more than two auxiliaries electrical 12 are present.
- the exit lever 24 rotates counterclockwise around of the third fixed point A3 of the housing 16, as shown schematically by an arrow F10 in FIG. 8, which, by his finger 56 and the mechanical link L2 to which it belongs, triggers the differential switch 11, by providing it, by the contribution thus made means elastic 59, all the energy necessary for this triggering.
- the tripping of the differential switch 11 causes its turn that of the electrical auxiliaries 12.
- the differential switch 11 ensures, by itself, when triggered, interface reset adaptation 10 according to the invention.
- the tilt lever 92 remains first motionless, the time that, by its circular portion 107, the cam surface 106 of the input lever 20 remains in contact of the right pan 110 of its boss 98, which ensures advantageously a temporary holding of the blade 90 of the means switching 89 in the position that is hers for the closing state of the differential switch 11.
- the tilt lever 92 ensures the return of the blade 90 of the switching means 89 to its initial position, as shown.
- the tilting lever 92 intervenes then under the sole solicitation of the elastic means 59, which relax, without taking any energy, in the switch differential 11.
