Embodiment Construction

[0017] exist figure 1 In , there can be seen a contact strip 1 belonging to a circuit breaker in a known manner, a bimetallic strip 2 and an angle arrester 3, the bimetal strip 2 representing the thermal tripping device of the circuit breaker, enabling the circuit breaker contacts to Opens on electrical overload. The bimetal strip 2 and the contact strip 1 are electrically connected by a braid 4 which is fixed via its one end 4a to the contact strip 1 and via its opposite end 4b to the supporting bimetal strip The support member 5 of the foot 2a.

[0018] exist figure 1 , the strip is in the installed position prior to assembly. The strip does not have any memory shape. Before assembling the assembly in the circuit breaker housing, first the bimetallic strip 2 must be manually arranged on the correct side of the contact strip 1 and then inserted into its receptacle. The bimetallic strip must then be inserted into its housing in order to finally compact the strip in its ho...

Abstract

The invention relates to a device for electrical connection and a circuit breaker. The device is applied in an electrical switch device to connect a foot of a bimetal strip with a contact strip. The bimetal strip can be moved via an adjusting screw so as to be thermally adjusted. The device is characterized in that the device has a flat conductive component (6) fixed on the contact strip (1) and the bimetal strip (2), wherein the conductive component is formed by at least one continuous conductive element. The conductive element is wound and flattened, so as to have a length substantially corresponding to a gap between the foot of the bimetal strip and the contact strip and to have a semi-rigid structure. The semi-rigid structure permits the deformation of the conductive component under the adjusting effect of the adjusting screw (7) so as to permit the displacement of the bimetal strip (2), while being sufficiently rigid for assuring relative positioning of the foot of the bimetal strip with respect to the contact strip.

Description

technical field [0001] The invention relates to an electrical connection device for electrically connecting the legs of a bimetallic strip to a contact strip in an electrical switching device, said bimetallic strip being movable by means of an adjusting screw for thermal regulation of the bimetallic strip. Background technique [0002] Connecting devices comprising woven braids for the electrical connection between the legs of the bimetallic strip and the contact strips in circuit breakers are known. However, these bands are bulky. Furthermore, the elements connected by the strip, ie the bimetallic strip and the contact strip, must be installed respectively in the circuit breaker before the strip is fitted in its housing, said strip having to be shaped so as not to memorize its shape. This shaping of the strip into the receptacle is restricted and requires the use of special tools. Contents of the invention [0003] The present invention solves these problems and propose...
