, Description:TECHNICAL FIELD
[0001] The present disclosure relates generally to electrical distribution systems. In particular, the present disclosure relates to an improved plugin distribution block assembly.

BACKGROUND
[0002] Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[0003] An electrical distribution board distributes electrical power from one or more incoming power supply terminals to a number of outgoing power supply terminals. Typically, the electrical distribution board comprises one or more bus conductors, which run the length of the board. The bus conductors carry the incoming electrical power to one or more outgoing Plugin conductors, which are, in turn, connected to one or more circuit breakers of the outgoing circuit.
[0004] In distribution systems, the final section before connecting the power to the load is the electrical apparatus. Electrical connections to the electrical apparatus are made by cable or links through bolted connections. Load is then connected to the electrical apparatus through suitable cables. In some areas, distribution blocks are also available through which easy connections to the device (Electrical Apparatus such as Switches and Circuit Breakers) with the Distribution busbar can be made. Such distribution blocks are used to connect the electrical device easily to tap off the electrical energy from the distribution busbar.
[0005] In an existing distribution block adapter, the type of connection used to make electrical contact with the distribution bus is butt-type contact system, i.e., the mechanical contact between the adapter link (prefabricated link) and the distribution busbar is established by a spring force applied on top of the adapter link as shown in FIG. 1. Due to this, effectiveness of current carrying capacity is reduced, and therefore the rating of the device adapter is limited, which allows the device adapter is only capable of connecting small rated devices such as miniature circuit breakers and contactors (low current carrying devices). Also the device adapter is capable for connecting only 3 busbars. i.e., R-phase, Y-Phase and B-phase, and therefore there is no provision for neutral connections. Furthermore, orientation of distribution busbar is horizontal, making size of the distribution block bigger.
[0006] There is therefore a need in the art for an improved distribution block assembly.

In another aspect, orientation of the proposed busbar is vertical whereas in the existing prior arts, the orientation of the busbar is horizontal and the links are faced parallel. An advantage of placing the proposed busbar vertically is that it considerably reduces overall dimension of the distribution block. Electrical connection in the present invention is made by plugin contacts in which one end is connected to the busbar, and the other end is connected to a rigid conductor that is in turn connected to the device intended to connect through rear termination of the equipment.
[0076] While the foregoing describes various embodiments of the invention, other and further embodiments of the invention may be devised without departing from the basic scope thereof. The scope of the invention is determined by the claims that follow. The invention is not limited to the described embodiments, versions or examples, which are included to enable a person having ordinary skill in the art to make and use the invention when combined with information and knowledge available to the person having ordinary skill in the art.
