Abstract: A package for communication equipment has a housing fitted with a locking mechanism and electrical/communication power supply and distribution, and includes UP, DOWN, RIGHT, LEFT faces for assembly with other housings. The locking mechanism includes a rotatable axle penetrating the housing and having a first end located outside of the housing and a second end located inside of the housing. A camming hook having a distal end is mounted on the rotatable axle inside the housing to rotate with the axle and locks into position when rotated in a first direction, to bring a movable electrical contact to make resilient electrical contact with a stationary live contact. When the rotatable axle is rotated in a direction opposite to the first direction, the mechanism becomes unlocked and breaks the electrical connection at the movable electrical contact.

Abstract: A package for a communication equipment fitted with mechanical locking mechanism and electrical and communication connectivity for allowing power supply distribution as well as communication at least at four distinctive faces (UP, DOWN, RIGHT, LEFT). Each communicating face is fitted with optical transmission and reception devices allowing digital communication between adjacent apparatuses. Each package comprises two faces having each one protrusion at one surface that is intended to enter into a groove machined at a corresponding surface of the next adjacent package in said structure. Each protrusion comprises a locking mechanism for power supply that comprises a camming hook (2200) having a distal end which forceably engages a locking aperture (2210) when pivoted. The hook is pivotally coupled to an axel (2101) extending respectfully through an elongated aperture (2301) formed at one end of a lever arm (2300), and an elongated aperture (2302) of the hook.
