Definitions
- the invention relates to an electrical switchgear comprising a movable rod and a flexible electrical connection between the movable rod and a fixed connection pad.
- the document EP 0 058 519 describes a switchgear whose contact member mobile comprises a cylindrical rod movable in translation along its axis.
- This rod is connected to an external connection pad via a flexible conductor consisting of a stack of metal strips.
- Each metal strip has a circular opening with tabs protruding out of the plane of the metal strip, towards the center of the opening.
- To mount the flexible conductor on the rod introduce the rod in the strip openings, then we take the conductors sandwiched between two clamping plates.
- the plates are connected to each other by bolts. When we tightens the bolts, the plates tend to compress the metal strips of the conductor flexible in the region with the openings, causing deformation and creep legs in contact with the stem.
- the area force adjustment which ensures the passage of current between the rod and the conductor mobile, has a high resistivity and that it is subjected, during the passage of the current nominal, to a heating which tends to cause differential expansions of the different elements, due to differences in the expansion coefficients of the materials constituting the rod on the one hand, and the stack of metal plates on the other. AT this expansion effect is added to the tendency of materials to creep under the influence of temperature, particularly in the force adjustment zone. In addition, any initiation of local deterioration of the junction tends to worsen over time, because it locally causes an increase in resistivity which causes an increase in temperature. The reliability of the fixing is thereby reduced.
- the invention therefore aims to remedy the drawbacks of the state of the art and to propose a junction zone between the movable rod of a switchgear and a connection flexible electric, which has excellent current conduction properties, which is light, reliable over time, and simple to manufacture.
- the monobloc assembly constituted by the welded assembly of the metal blades at the level of the first rigid end part, ensures good mechanical strength of all. Brazing ensures a metallurgical connection between the rod and the conductor flexible.
- the metallic filler compound has a determined melting point, depending on the chemical elements constituting it, lower than the melting points of metallic parts that it allows to link. Indeed, the parts to be joined, in this case the rod and the connector flexible, must not participate by fusion in the constitution of the joint during assembly pieces.
- the melting point of the solder is substantially less than 900 ° C, and preferably less than 700 ° C.
- the choice of solder at a temperature of low melting must not be done at the expense of the electrical conductivity of the gasket soldering, or at the expense of its mechanical strength.
- the metallic compound filler is a silver-based compound in proportions greater than 30%, with a supply of tin in proportions of less than 10%. More particularly, we will prefer proportions greater than 50% in silver, with a contribution of tin in proportions less than 6%. Silver gives the solder excellent electrical conductivity.
- Tin for its part, lowers the soldering temperature, but has the defect of rendering ductile brazing (soft brazing), which is not desired. This is why the proportion tin should remain weak.
- a quaternary compound Ag-Cu-Zn-Sn According to an exemplary embodiment, the compound is quaternary and contains 56% silver, 22% copper, 17% zinc and 5% tin, with a melting point of around 650 ° C. The solder does not contain cadmium, despite the known property of this component to lower brazing temperatures, due to its potential harmfulness to the environment.
- the metallurgical bond obtained ensures excellent electrical conduction. She does not increase the mass of the moving part, so that the kinetic energy to be dissipated at the end of the opening or closing stroke remains relatively low. Brazing once performed, the junction is not sensitive to temperatures of the order of 100 ° C. at which it is subjected during the passage of the current, so that it does not deteriorate in the time under the influence of temperature.
- the projecting part of the rod has an axis, limited on the side of the bulb by a shoulder, part of the filler compound constituting a joint interface interposed axially between the shoulder and an axial rim of the bore, and another part of the filler compound constituting a radial interface seal between the bore and the axis.
- the axis constitutes a free end of the rod, so that the assembly operation is particularly simple. In fact, it suffices to successively insert a washer of brazing, then the bore of the connection, before performing the brazing operation.
- the axis is of circular section, as well as the bore, so that the seal radial interface between the bore and the axis has a cylindrical shape, which allows overcoming the radial positioning constraints of the link relative to the axis.
- the welding is carried out by bombardment welding electronically or electronically, without adding metal.
- the flexible connection comprises a second rigid end part, constituting a connection pad provided with means for connection to the busbar, the flexible part being located between the first and the second rigid parts.
- the link flexible then simultaneously performs the flexible connection function and the beach function connection for a busbar. It is possible to provide bores, tapped or no, for fixing to the busbar.
- the flexible connection is consisting of a stack of metal blades, joined together by welding at said first and second rigid end portions, the blades remaining independent of each other in the flexible part of the connection.

- the turn 29 is intended to induce, in the separation zone of the contacts 22, 24, a magnetic field conducive to breaking an incipient electric arc between the contacts during their separation. Screws secure the turn 29 to the frame 12, and therefore the rigid attachment between the cylinder 26, itself integral with the body 17 of the bulb, and the frame 12. Furthermore, and as will be explained below in detail, the first flange 20 is positioned and maintained relative to the frame 12 by means of a fixing collar 100 retained in a groove 130 of the frame.

- Nut 46 has a shoulder which comes to rest on the part of the bar 83 opposite the second plate 49.
- the two arms 81, 82 of the lever 80 pivot around an axis 86 supported by the frame 12 and are actuated jointly at their free end by a closing mechanism and opening (not shown), this mechanism being intended to drive the contact member movable 30 between a position of contact with the fixed contact member 28 and a position of separation.
