The following specification particularly describes the invention and the manner in which it is to be performed.

Busbar Support Assembly
Field of the invention
The present invention relates to an assembly for supporting conductors, and more particularly, to the assembly for supporting busbars used for distribution of electrical energy.
Background of the invention
Conductors are used in electrical control panels, busducts and the like for carrying and/or distribution of electrical energy. The conductor, for example, a busbar is a strip or bar of copper, brass or aluminium that conducts electricity within a switchboard, distribution board, substation, battery bank or other electrical apparatus.
Generally, the busbars are required to be protected in normal condition as well during abnormal conditions such as short circuit fault. Currently available busbar support systems are not efficient in protecting the busbars. Specifically, the support systems cannot withstand electromagnetic forces developed during short circuit condition. Further, the busbar support systems are not easy to assemble.
Accordingly, there exists a need to provide an assembly for supporting busbars which overcomes the drawbacks of the prior art.
Objects of the invention
An object of the present invention is to protect busbars in normal condition as well during abnormal conditions such as short circuit fault.

Another object of the present invention is to provide busbars which withstands the electromagnetic forces developed during short circuit condition.
Summary of the invention
Accordingly, the present invention provides a busbar support assembly. The busbar support assembly comprises a first griping member comprising a plurality of slots configured thereon for accommodating the plurality of busbars therein. Further, the busbar support assembly comprises a second gripping member capable of receiving the first gripping member therein. The second gripping member includes a base member supporting the first gripping member. Walls extend from at least two sides of the base member for restricting widthwise movement of the first gripping member. The stoppers are provided on the base member near ends of the walls for restricting depthwise movement of the first gripping member, and at least one protrusion is provided on inner side of the walls for restricting heightwise movement of the first gripping member. At least two notches are configured on lower side of the base member. Furthermore, the busbar support assembly includes a channel having at least two slots corresponding to the notches on the second gripping member for receiving the second gripping member thereon.

Detailed description of the invention
The foregoing objects of the present invention are accomplished and the problems and shortcomings associated with the prior art, techniques and approaches are overcome by the present invention as described below in the preferred embodiments.
The present invention provides a busbar support assembly which protect busbars in normal condition as well during abnormal conditions such as short circuit fault. Specifically, the busbar support assembly withstands the busbar from electromagnetic forces developed during short circuit condition.
Referring now to figure 4, there is shown an assembled view of a busbar support assembly (100) (hereinafter 'the assembly (100)'), in accordance with the present invention. The assembly includes a first gripping member (10), a second gripping member (30) and a channel (50).
The first gripping member (10) as shown in figure 1 and 2, includes a plurality of slots (08) configured thereon for receiving a plurality of busbar (not shown) therein. The slots (08) on the first gripping member (10) are formed by spaces between strips extending from both sides of a base thereof. The slots (08) vary according to the busbar cross section and number of flats tc be used for particular current rating. In an embodiment, the first gripping member (10) is made of steel. However, it may be evident to those skilled in the art that any

other suitable material known in the art may be used to construct the first gripping member (10).
The second gripping member (30) as shown in figure 3, is capable of receiving the first gripping member (10) therein. The second gripping member (30) includes a base member (12) supporting the first gripping member (10) thereon.
Further, the second gripping member (30) includes walls (14a. 14b) extending from at least two sides of the base member (12) for restricting widthwise movement of the first gripping member (10). The walls (14a, 14b) are capable of being stretched in outward direction when receiving the first gripping member (10).
Furthermore, the second gripping member (30) includes stoppers (16) provided on the base member (12) near ends of the walls (14a, 14b) for restricting depthwise movement of the first gripping member (10).
Moreover, the second gripping member (30) includes at least one protrusion (18) provided on inner side of the walls (14a, 14b) for restricting heightwise movement of the first gripping member (10). The base member (12), the walls (14a. 14b), the stoppers (16), and the protrusion (18) restrict movement of the first gripping member (10) in all the three directions.
The second gripping member (30) also includes at least two notches (22) configured on lower side of the base member (12).
In an embodiment, the base member (12), the walls (14a, 14b) , the stoppers (16), the protrusion (18) and the notches (22) are moulded together to form a single unit second gripping member (30). In an embodiment, the second gripping member (30) is made of suitable polymer known in the art. However, it may be evident to those skilled in the art to mould the second gripping member

(30) from any other material known in the art. The second gripping member (30) gets inserted in the channel (50).
Specifically, the channel (50) includes at least two slots (42) corresponding to the notches (22) on the second gripping member (30) for receiving the second gripping member (30) thereon. In an embodiment, the channel (50) is C-shaped channel. The width of the channel (50) is slightly more than that of the gap present in the notches (22) of the second gripping member (30). While inserting the second gripping member (30) inside the channel (50), the second gripping member (30) gets flexed which is placed in the slots (42) of the channel (50).
During assembly of the assembly (100), the first gripping member (10) has to be inserted in the second gripping member (30). While inserting the first gripping member (10), the walls (14a, 14b) of the second gripping member (30) get stretched outward. Once the first gripping member (10) and the second gripping member (30) are assembled together, the second gripping member (30) has to be inserted in the slots (42) of the channel (50) as shown in figure 4 to form the assembly (100).
When cross section and number of busbars change, only the first gripping member (10) has to be changed, whereas, the second gripping member (30) and the channel (50) remains same. Figures 5 and 6 shows different busbar cross sections and the number of busbars wherein the second gripping member (30) and the channel (50) is same.
The foregoing descriptions of specific embodiments of the present invention have been presented for purposes of illustration and description. They are not intended to be exhaustive or to limit the present invention to the precise forms disclosed, and obviously many modifications and variations are possible in light of the above teaching. The embodiments were chosen and described in order to best explain the principles of the present invention and its practical application,

to thereby enable others skilled in the art to best utilize the present invention and various embodiments with various modifications as are suited to the particular use contemplated. It is understood that various omission and substitutions of equivalents are contemplated as circumstance may suggest or render expedient, but such are intended to cover the application or implementation without departing from the spirit or scope of the present invention.
