Casing for slide=in communications units - has four sides, base plate and cover plate and security seal

摘要

The casing holds several rectangular slide-in communications units which are located inside the casing parallel to two of the casing's four side walls and perpendicular to the casing's base plate and cover plate. The base plate (B) is connected to the cover plate (D) via three side plates (S1-S3). The fourth side plate (S4) acts as a removable cover and is connected to the base plate, to the cover plate and to the two sides (S1,S3) parallel to the units. The fourth side plate is stepped and has its smaller step (S41) provided with a hole (S43) through which a plug slides into the unit. The fourth side plate is connected to a security sealing system (P) (e.g. lead wire) near the cover plate.
