Even if it is inserted into the socket, there is no danger that the power plug will be loosened or come off and the electrical connection will be poor, just like a small-diameter socket. An electrical connection can be obtained and an extremely reliable car plug can be provided.

Abstract

L'invention se rapporte à une borne élastique pour fiches d'automobiles, qui est introduite dans une prise d'allume-cigares d'une automobile, en vue d'alimenter divers dispositifs. Une telle borne élastique peut être maintenue de façon trés stable, même lorsque la prise de l'allume-cigares a un diamètre différent qui dépend du fabricant de l'automobile. La fiche d'automobile comporte un corps cylindrique pour une petite prise d'allume-cigares typique des voitures japonaises. La borne élastique adaptée à la fiche d'automobile présente une partie de base en forme de rondelle destinée à s'adapter à l'extrémité du corps cylindrique et comprend au moins trois pièces en forme de plaques qui s'étendent radialement de façon équidistantes depuis la périphérie de la partie de base, chaque pièce en forme de plaque ayant une base pliée à l'extrémité quasiment à angle droit dans quasiment la même direction, afin de former une partie d'introduction introduite dans le corps à l'extrémité et un contact souple formé par pliage vers l'extérieur d'une partie entre la partie d'introduction et la partie de base, façon à déborder de la circonférence du corps. Même lorsque la fiche d'automobile conçue pour être utilisée avec des petites prises d'allume-cigares typiques des voitures japonaise est introduite dans une grande prise d'allume-cigares d'une voiture européenne, la borne élastique produit une pression élastique dans un sens radial, de sorte que la fiche d'automobile est maintenue de façon fiable, assurant ainsi une connexion électrique stable.
