Embodiment Construction

[0054] refer to figure 1 , where a circuit breaker 1 is shown, here provided with a molded insulating case B, conventionally comprising a control handle 2 via a mechanical lock 3 (not described in detail as it does not constitute the invention) is connected to a contact carrier 4 supporting a movable contact 5 arranged for cooperation with a fixed contact 6 .

[0055] On both sides of the fixed contact 6 / movable contact 5 pair are arranged connecting means for connecting to the lines 7, 8 to be protected. The mechanical lock 3 transmits the movement of the control handle 2 . Thus, the control handle 2 is tilted to the two ends of the path of rotation that it can traverse in the housing, these two ends corresponding to two stable positions, said two stable positions each embodying A state of the contacts: either open and at a distance from each other, or closed and resting on each other.

[0056] The mechanical lock 3 notably comprises a toggle mechanism allowing the movemen...

Abstract

The invention relates to a device for protecting equipment with at least one movable contact, having a number of housings equal to the number of movable contacts, relative to which the movable contact is allowed to pivot Housing fixed support, and two torsion / compression coil springs on either side of the pivot connection. The spring comprises a straight end arranged to bear against an inner face of the receptacle and a curved end arranged to attach to a lug, the lug Protrudes from an end of a movable contact provided in the accommodating portion. The tab and the bent end of the spring are constructed and oriented such that the bent end of the spring exerts a dual force on the tab. Said tabs additionally exert a force substantially along the same directional line, but in a direction opposite to the reaction force exerted by the inner face on the straight end bearing against said face.

Description

technical field [0001] The invention relates to a device with at least one movable contact, which is used in a protective device of a line, such as a circuit breaker or a differential device or the like. The invention thus belongs to the field of devices that are conventionally inserted on at least one power line and that ensure the protection of installations downstream of said device. Background technique [0002] In this case, for each line, these protective devices comprise a fixed contact and a movable contact arranged between the connecting means of this line. The movable contact, which must have a certain range of movement, generally takes the form of a swivel arm, at the free end of which a contact piece is fixed, said arm being able to bear in the closed position against the piece of the fixed contact and in contact with the The stationary contact pivots between open positions spaced apart by a certain distance. [0003] In the event of a problem with the circuit ...
