An electronic device includes a rack, a mount housing in which an electronic component is housed, and mounted in the rack from a front face side or rear face side of the rack, and a movable duct configured to have a housed state where the movable duct is retracted from an opening formed in a sidewall part of the mount housing and is housed in the mount housing and an opened state where the movable duct is moved to outside of the mount housing through the opening so as to form a ventilation flue located outside the mount housing and communicating with the opening.

Electronic device

A printed board to be loaded into a printed-board-receiving structure having a backboard and a guide rail, the backboard having a connector plug-in connectable to a connector on the printed board, the guide rail guiding the printed board toward the backboard and having a groove including a sloping portion, the printed board includes a sloping portion forming a projection at an end of the printed board, the projection being fittable and slidable along the groove in the guide rail.

Printed board and printed-board-receiving structure

A release auxiliary device () includes a base part () that is provided fixedly with respect to a receptacle (), and an auxiliary lever () that is provided elastically deformable with respect to the base part () and elastically deformable in an orthogonal direction with respect to a direction in which a lever () is deformed. The auxiliary lever () includes an inclined pressing part () that is touchable, from a side, to an end portion of the lever (), the inclined pressing part () presses against the end portion of the lever () and moves the lever () by pressing an outer surface side of the auxiliary lever () and deforming the auxiliary lever (), enabling release of the engagement between engaging portions ().

Retention release auxiliary device for optical connector and printed circuit board device

A release auxiliary device () includes a base member () fixedly provided with respect to a receptacle (), and an auxiliary lever () provided in an elastically deformable manner with respect to the base member (). The auxiliary lever () has a base part () extending to the base member (), a pressing part that extends to the base part and is touchable to an end portion of a lever (), and an operating part () that extends to the pressing part and is disposed at a position closer to the body of the plug than the end portion of the lever is. By operating the operating part () with fingers, the pressing part () presses against the end portion of the lever () and moves the same, so that the engagement between engaging portions () for retention can be released.

A release auxiliary device () includes a cover part () that is provided movably with respect to a receptacle () along the insertion/removal direction of a plug (), and an inclined pressing part () that is provided in the cover part () and is touchable, from a lower side, to an end portion () of a lever (). The inclined pressing part () presses against the end portion () of the lever () and moves the lever by moving the cover part () in a direction in which the plug () is detached, enabling release of engagement between engaging portions ().
