R. N. ROWE April 27, 1965 BUSWAY .CONNECTOR 2 Sheets-Sheet 2 Filed June 28, 1963 United States Patent greases BUSWAY CQNNECTUR Raymond N. Rowe, Wakefield, RJL, assignor to General Electric Company, a corporation of New York Filed June 28, 1963, Ser. No. 291,374 2 @iaims. (Si. 174dt3) This invention relates to connectors, more particularly to connectors for electrically connecting the bus conductors at a joint between adjacent sections of a multisection busway, and it has for an object the provision of a simple, reliable, inexpensive and efficient connector of this character.
More specifically, the invention relates to a connector for two or more busbars in a busway and a more specific object of the invention is the provision of a single stab-in busway connector for two or more busbars.
Another object of the invention is the provision of a stab-in type busbar connector which is readily and easily installed.
Still another object of the invention is the provision of a stab-in busway in which the contact pressure on the busbars may easily be adjusted to any desired value within a range of permissible values.
In carrying the invention into efiect in one form thereof, a block of insulating material having mating cover and base sections is provided with a pair of parallel ducts separated by a partition and extending through the block from end to end to provide for insertion of a busbar in each end of each duct. In final position, the busbars in the parallel ducts are in parallel flat face to flat face relationship with each other, and the two busbars in each duct are in end to end relationship with each other. Separate contact bridging members in each duct make overlapping contact with a substantial portion of the flat surfaces of both of the end to end busbars therein. A spring mounted in a hole through the partition and insulated from the busbar in one of the ducts urges a bridging contact in each duct into contact with the end to end aligned busbars therein. The connector may comprise two or more two pole sections held together by a fastening means which furnish additional contact pressure when tightened.
For a better and more complete understanding of the invention reference should now be had to the following specification and to the accompanying drawings in which:
FIG. 1 is a view in perspective of adjacent sections of a busway mechanically and electrically joined by a connector embodying the invention.
FIG. 2 is a view in section taken on the line 2-2 of FIG. 3 of a bus connector embodying the invention.
FIG. 3 is a view in section taken on the line 3-3 of FIG. 1 of the connector.
FIG. 4 is a view in perspective of one section of the molded base member of the connector, and
FIG. 5 is a view in perspective of a two section base assembly of a connector embodying the invention with one of the bridging contacts removed from its position in the assembly to reveal internal structural details.
Referring now to the drawings and particularly to FIG. 1 the busbars in sections 1 and 2 of a multisection busway are connected together by a two section connector 3 having two 2-pole sections 3a and 3b. Each busway section 1 and 2 has an elongated housing or enclosure comprising a generally channel shaped top member 4 and a fiat bottom wall member 5.
The two housing sections are joined together by a sleeve member 6 in which the connector 3 is captured.
Four busbars 7, 3, 9 and 1d are mounted in the bus- Way section 1 and are supported therein by suitable insulating supports (not shown). In section 2 of the busway four corresponding busbars 7a, 8a, 9a and Illa are similarly mounted and supported. Although the busway illustrated is of the 4-bar type, the invention is applicable to busways having either a greater or a lesser member than four bars.
Each of the connector sections 3a and 3b has a molded block base section 11 and an identical molded block cover section 12 made of a suitable molded insulating compound. Each of the base blocks 11 is provided with two longitudinally disposed parallel ducts 13 and 14 as shown in FIG. 4 and each of the cover blocks is provided with two corresponding longitudinally disposed ducts. The cover and base blocks are identical and when mounted in mating relationship, the corresponding ducts in base and cover blocks are in register and constitute a complete duct in which a busbar may be inserted at either end. In order that the busbars may be easily inserted in the connector, the sidewalls of the ducts are beveled at both ends to provide a busbar entrance that diverges outwardly toward the end.
Within each or" the ducts 13 and 14 are mounted a pair of bridging contacts 15' and lid. These bridging contacts are short flat straps and are made of a good conducting material such for example as copper or aluminum. As shown, each of these contacts has a bent portion at each end, such as the portions 16a and 16b of contact 16, and the sidewalls of the ducts 13 and 14 are recessed near their ends to receive the bent ends of the bridging contacts. For example, the sidewalls of the duct 14 near their ends are provided with recesses 17 and 18 to receive the bent ends 15a and 15b of contact 1% and are also provided with recesses 19 and 2G to receive the bent ends 116a and 16b of contact 16. The bent ends of bridging contacts provide sufiicient divergence at their ends to facilitate easy insertion of the busbars into the space between each pair of bridging contacts.
The base block 11 of each section of the molded insulator has a plurality of semicircular depressions molded in the top surface of the sidewalls and partitions between the two ducts 13 and 14. As best shown in FIGS. 4 and 5, the inside sidewall of the base block 11 has molded depressions 21, 22 and 23 and the partition between the ducts 13 and 14 has depressions 24, 25 and 2d. The outside sidewall has a centrally disposed semicircular depression 221: molded in its top surface. When the identical cover block 12 is placed on the base lock 11 in mating relationship the mating depressions in both base and cover blocks form complete holes.
Within the holes formed by depressions 24 and 26 in the base and mating depressions in the cover are mounted insulation cup members 27 and 28 and within these insulating cups are mounted springs. As shown in FIG. 2, spring 29 and 2% are mounted in insulating cups Z7 and 28 respectively. Thus, in the assembled connector, the spring 29 bears against one of the bridging contacts in duct 14 and the end of the insulating cup is forced by the spring to bear against one of the bridging contacts in duct 13.
When two 2-pole sections are assembled in parallel side by side relationship to form a 4-pole connector, insulating rods 3% and 31 are mounted in the holes formed by depressions 21 and 23 in the sidewall of one of the insulating blocks and in the holes in alignment register therewith in the sidewall of the adjacent insulator block. In the completed assembly, the rods 30 and 31 are situated between bridging contacts in adjacent insulating blocks and thus constitute a solid base against which the bridging contacts in adjacent ducts of adjacent sections of the insulating blocks are pressed when the sections themselves or the assembly of a plurality of such sections are compressed.
The complete assembly of two or more blocks is held together by means of a screw 32 which passes through the hole formed by depressions 22, 22a and 25 in both sections of the insulator and the holes 150 and Me in the bridging contacts. A sleeve 33 of insulating material insulates the screw from the bridging contacts.
The molded base 11 and the molded cover plate 12 are provided with integral molded bands 11a and 12a respectively. When the base and the cover are assembled the bands 11a and 12a constitute a single band encircling the assembly. This continuous band is raised a suitable amount, e.g., V inch above the outer surfaces of the base and cover plate. It serves to position the connector accurately in the housing sleeve 6. Clearance holes 6a and 6b are provided in the sleeve 6. This permits full application of the clamping force of screw 32 to the molded member. The pressure of the bridging contacts against the flat faces of the busbars may be increased by tightening the screw 32 to force both sections of the connector toward each other.
As many 2-pole units as may be required may be grouped together to connect the busbars of adjoining lengths of the busway with normally spring pressed contacts and with the additional feature of being able to increase the contact pressure by means of a clamping screw.
Alterations and modifications in the connector illustrated described may be made without departing from the true spirit of this invention or from the scope of the annexed claims.
