Abstract

L'invention concerne une poignée pour insérer/retirer une carte de circuit imprimé. Cette poignée comprend un élément de poignée (2) et une partie de support de poignée (3). Cette partie de support de poignée est pourvue d'une tige (34) formant pivot de support insérée en vue de sa rotation dans le corps (110a) de la carte, de telle sorte que la partie de support de poignée peut tourner par rapport au corps de la carte. L'élément de poignée est pourvu au niveau de sa première extrémité d'une tige formant pivot (21) d'élément de poignée et au niveau de sa deuxième extrémité de parties de compression (23 , 24) et d'une partie de mise en prise (25). De plus, la tige de pivot de l'élément de poignée est insérée en vue de sa rotation dans la partie de support de poignée, de telle sorte que la deuxième extrémité de l'élément de poignée peut tourner sur la tige de pivot de l'élément de poignée et la tige de pivot de la partie de support à partir de l'état dans lequel elle se situe, sur un panneau avant (111) fixé sur le corps de la carte, pour passer dans l'état dans lequel elle se trouve par rapport au corps de la carte. Dans l'état placé sur le panneau avant, la partie insérée est en prise avec une partie de mise en prise avec la poignée (112) fixée sur le corps de la carte.
