Abstract

Borne pour un appareil électrique une borne (1) comprenant : un étrier (4), qui comprend un orifice principal traversant (12) avec un premier filetage intérieur (14) ; une vis (5), la borne (1) présentant une configuration engagée, dans laquelle un premier filetage extérieur (42) de la vis est vissé avec le premier filetage intérieur (14) ; et un capuchon (6), qui comprend un pallier (66), qui guide et capture la vis, et un guide (68), qui guide en translation le capuchon (6) par rapport à l’étrier (4). Pour assurer un serrage correct de la vis et éviter une détérioration du capuchon, l’invention prévoit que la borne (1), tout en restant facile à fabriquer, présente une configuration débrayée dans laquelle une partie non filetée (44) de la vis est disposée à hauteur du premier filetage intérieur (14), la partie non filetée (44) maintenant ainsi la vis (5) centrée dans l’orifice principal traversant (12). Figure pour l'abrégé : figure 2Terminal for an electrical appliance a terminal (1) comprising: a yoke (4), which comprises a main through hole (12) with a first internal thread (14); a screw (5), the terminal (1) having an engaged configuration, in which a first external thread (42) of the screw is threaded with the first internal thread (14); and a cap (6), which comprises a bearing (66), which guides and captures the screw, and a guide (68), which guides the cap (6) in translation relative to the yoke (4). To ensure correct tightening of the screw and to prevent damage to the cap, the invention provides that the terminal (1), while remaining easy to manufacture, has a disengaged configuration in which an unthreaded portion (44) of the screw is disposed at the height of the first internal thread (14), the non-threaded part (44) thus maintaining the screw (5) centered in the main through hole (12).
