The invention relates to a connector element for two installation breakers, adjacently attached with the broad faces thereof in contact, in particular, power breakers or residual current breakers, the housings of which are each formed from two dished housing pieces. The connector element comprises an approximately cylindrical base body (34) with a first external diameter (d2), on the front side (35, 36) of which two radially-sprung, axially projecting first (37, 39) and second (38, 40) expanding arms are moulded. The external contours of the spreader arms lie on a cylindrical outer surface, the external diameter (d3) of which is smaller than the first external diameter of the base body (34). The free ends thereof comprise radially projecting lugs (41, 42, 43, 44) on opposed external lines, which, in the assembled state, clip behind recesses (58, 57) on the housings, for connection by means of the connector element, of adjacent installation breakers (10, 11). A sprung spreader element (70) is mounted between a first (37, 39) and second (38, 40) spreader arm such that the spreader element (70) supports the sprung spreading of the spreader arms (37, 38, 39, 40) and which impedes the sprung contact of the first (37, 39) and second (38, 40) spreader arms with each other.

L'invention concerne un élément d'assemblage permettant d'assembler deux commutateurs d'installation juxtaposés avec les côtés plats l'un contre l'autre, en particulier des disjoncteurs de protection de circuit ou des disjoncteurs différentiels à courant résiduel, commutateurs dont les boîtiers sont constitués de deux parties de boîtier cupuliformes. Cet élément d'assemblage comporte un corps de base approximativement cylindrique (34) pourvu d'un premier diamètre extérieur (d2), deux premiers (37, 39) et seconds (38, 40) bras écartables, saillant axialement et se détendant radialement, étant formés sur les faces (35, 36) dudit corps. Les contours extérieurs des bras écartables reposent contre une surface enveloppante cylindrique, dont le diamètre extérieur (d3) est inférieur au premier diamètre extérieur du corps de base (34), et les extrémités libres de ces bras présentent des nez (41, 42, 43, 44) saillant radialement sur des génératrices opposées. A l'état monté, ces nez viennent s'encliqueter derrière des renfoncements (58, 57) sur les boîtiers des commutateurs d'installation juxtaposés (10, 11) à relier à l'élément d'assemblage. Un élément d'écartement élastique (70) est placé entre un premier (37, 39) et un second (38, 40) bras écartable, de sorte que cet élément d'écartement (70) aide les bras écartables (37, 38, 39, 40) à s'écarter en détente et rend la compression des premiers (37, 39) et seconds (38, 40) bras écartables plus difficile.
