Abstract

L'invention concerne une douille de contact (1), destinée à des prises de courant (9a) ou à des prolongateurs, qui comprend deux branches de douille (2a, 2b) élastiques, formant un orifice d'insertion (3), entre lesquelles une broche de contact (10) d'une fiche peut être serrée grâce à la déflexion élastique des deux branches de douille (2a, 2b) lorsque la broche de contact (10) est insérée perpendiculairement au plan de déflexion dans l'orifice d'insertion (3). La douille de contact (1) comporte une fourche (12) qui possède des première et deuxième branches extérieures (4a, 4b) entre lesquelles sont formées des première et deuxième branches intérieures (5a, 5b). Les branches intérieures sont respectivement disposées aux extrémités libres (6a, 6b) des branches extérieures et forment une des branches de douille à chaque extrémité libre. Entre les branches de douille et les branches extérieures sont ménagées des zones libres (F, F') destinées à permettre la déflexion élastique des deux branches de douille vers l'extérieur dans lesdites zones libres lors de l'insertion de la broche de contact dans l'orifice d'insertion. Entre les branches de douille et les branches extérieures, en particulier sur la première et/ou sur la deuxième branche extérieure, est formé au moins un élément limiteur qui limite la déflexion de la première et/ou de la deuxième branche de douille.
