Locking/unlocking device for electronic boards located in onboard equipment

摘要

A locking/unlocking device for electronic boards, the boards being configured to be inserted into an electronic cabinet with at least one slotted plate fit into the rack of the electronic cabinet, the device including a substantially rectangular frame supporting at least one locking slide that locks the electronic board onto the slotted plate through the action of a locking element. The device further includes an extracting lever that rotates between a rest and a locking position around a lateral Y1 axis, the extracting lever fitted so that exerting force is possible along the longitudinal X axis between the electronic board, or the frame and the rack, with the locking unit including an extension to be placed outside, opposite the extracting lever along the longitudinal axis X of the board when the two levers are engaged in the locking position.

主权项

1. A locking/unlocking device for electronic boards, said boards to be inserted into an electronic cabinet with at least one slotted plate fit into the rack of said electronic cabinet, the locking/unlocking device comprising:
a substantially rectangular frame, adapted to form part of the electronic board, said frame supporting at least one locking slide that locks the electronic board onto the slotted plate through the action of a locking lever that moves between a rest position and a locking position; a direct reference system for the frame, said system comprising a longitudinal axis X parallel to the insertion direction of the frame in the electronics cabinet, and a vertical axis Z perpendicular to the axis X and situated on a plane parallel to the center plane of the frame, with a lateral axis Y perpendicular to the X and Z axis; and an extracting lever that rotates between a rest position and a locking position around a fixed Y1 axis and parallel to the Y axis, said extracting lever fitted so as to allow the application of a force along the longitudinal X axis between the electronic board, or the frame and the mounting rack, wherein the locking lever includes an extension adapted to lie outside in relation to the extracting lever along the longitudinal axis X of the board when the locking lever and extracting lever are engaged in the locking position, wherein the extracting lever and the locking lever engage at an intersection point, which corresponds to a position of the levers intermediate between their rest and locking positions.
