Device for inserting, extracting and locking an electronic card in a slot

A Device for clamping in a slot an electronic card comprising contacts able to be inserted into connectors via a longitudinal movement of said electronic card, guided by said slot extending longitudinally, between a first position of the electronic card, so called the extraction position, where the contacts are not inserted into the connectors, and a second position, so called the insertion position, where said contacts are fully inserted into the connectors;

• said device comprises:
• a) clamping means able to cause a tightening, so called transversal tightening, on sides of the slot;
• b) means of controlling the clamping means, having a sliding connection with the electronic card and able to cause the transversal tightening of the clamping means by a longitudinal movement of said means of controlling the clamping means relative to the electronic card;
• c) means, so called tightening means, comprising a first eccentric having a pivoting connection with the electronic card according to an axis perpendicular to the longitudinal direction and able to cause a longitudinal translation movement of the means of controlling the clamping means by a rotation of said tightening means around said pivot axis;
• d) wherein said tightening means comprise a second eccentric relative to the pivot axis working with means forming a bearing surface fully linked to the slot to produce an instantaneous center of rotation of the tightening means on said bearing surface when the electronic card is in the extraction position and the tightening means are operated around the pivot axis for inserting the electronic card.
