Cover for the screws with means for controlling fastening of the screws

摘要

The cover (5) has a unit controlling a tightening of a binding screw (4) in a screw cage and including studs (6) integrated to the cover and equal to the number of the screw cages inserted in orifices provided in front of an electric device. The studs have length, such that the cover is closed only when the screws are in tightened state. A hinge (8) is provided at a level of a ridge transversal to an end of the front of the electric device and is formed as a single part with the cover using a thin plastic film connecting the cover and an electric device casing (B).
