Terminal casing equipped with a removable hatch having a curvilinear profile

摘要

A terminal casing includes an one upper cover and one lower cover making a housing that can be closed by a removable hatch having a curvilinear profile. The hatch includes grooves distributed longitudinally on two parallel faces following the curvilinear profile. The lower cover includes tabs distributed longitudinally on two parallel faces in following the curvilinear profile, each tab cooperating with an associated groove. The tabs and the grooves are shaped to enable: through a translational motion followed by a rotational motion of the hatch, an insertion and a guidance of the tabs in the grooves of the hatch, when the hatch is inserted into the lower cover; and through a rotational motion followed by a translational motion of the hatch, a guidance of the tabs in the grooves of the hatch and a withdrawal of the tabs from the grooves when the hatch is withdrawn from the cove.

主权项

1. A terminal casing comprising:
at least one upper cover and one lower cover in which there is made a housing configured to be closed by a removable hatch having a curvilinear profile, wherein: the hatch, or the lower cover, comprises a plurality of grooves distributed longitudinally on at least two parallel faces along said curvilinear profile, the lower cover, or the hatch respectively, comprises a plurality of tabs distributed longitudinally on at least two parallel faces along said curvilinear profile, each tab of the plurality of tabs being designed to cooperate with an associated groove of the plurality of grooves, the hatch has a direction of insertion and a direction of withdrawal opposite to the direction of insertion, plurality of grooves of each face are each tilted relative to the curvilinear profile by an angle of tilt that increases in the direction of withdrawal of the hatch and decreases in the direction of insertion of the hatch, and the plurality of tabs of each face are each tilted relative to the curvilinear profile by an angle of tilt that increases in the direction of withdrawal of the hatch and decreases in the direction of insertion of the hatch.
