Abstract

L'objectif de la présente invention est de supprimer le mouvement d'un fil électrique le long de la direction d'extension du fil électrique et la rotation du fil électrique dans la direction circonférentielle d'une pince, dans une pince de fixation d'un fil électrique à un organe du côté opposé. Cette pince est équipée : d'une partie de support qui inclut une partie en saillie de support pouvant supporter la partie de fil électrique ; d'une partie de bande pouvant être enroulée autour de la périphérie de la partie de fil électrique supportée par la partie en saillie de support ; d'une partie de verrouillage de bande qui maintient la partie de bande enroulée autour de la périphérie de la partie de fil électrique, assurant ainsi le support de la partie de fil électrique par la partie en saillie de support ; et d'une partie de fixation du côté opposé qui est en saillie depuis la partie de support vers le côté opposé de la partie de fil électrique, et qui peut être fixée à un organe du côté opposé. La partie en saillie de support inclut : des premières parties en saillie formant des évidements pouvant loger au moins une partie de la partie de fil électrique ; et une saillie de positionnement qui est disposée à une position différente de la position des premières parties en saillie le long de la direction d'extension de la partie de fil électrique, et qui, lorsqu'elle est vue depuis la direction d'extension de la partie de fil électrique, dépasse depuis les évidements vers la partie de fil électrique.
