Solid connector for stator phase winding and method of assembly
First Claim
1. A half-coil connection for an electrodynamic system such as an electrical generator, comprising:
- a first half-coil comprising a first group of strands comprising more than one strand stack and a second group of strands comprising more than one strand stack;
a second half-coil comprising a third group of strands comprising more than one strand stack and a fourth group of strands comprising more than one strand stack;
four strand group clips secured, respectively, to said first, second, third and fourth groups of strands to bind said stacks within said strands together, said clips being electrically conductive;
a first conductor member affixed at a first end to said strand group clip on said first group of strands and affixed at a second, opposite end to said strand group clip on said second group of strands; and
a second conductor member affixed at a first end to said strand group clip on said second group of strands and affixed at a second, opposite end to said strand group clip on said fourth group of strands, whereby a solid connection between the half-coils is achieved which is less labor-intensive to install and is more durable than connections heretofore known.

Abstract
A solid series connector for electrically connecting a first half-coil to a second half-coil in a stator phase winding includes first and second solid conductor members which are fixedly electrically connected at both ends to groups of conductive strands in the respective half-coils. The connector is much less labor-intensive to install than the group transposition connections used in the past, is more rugged and durable under high temperatures and stresses, and is relatively compact. A second embodiment of the invention is a solid phase connector that incorporates many of the novel features in the solid series connector. A novel method of preparing a conductive strand group for connection to such connectors is also claimed.

7. A connection for electrically connecting a phase winding coil in an electrodynamic system such as a multiphase electrical generator to a conductive ring member in such a system, comprising:
-
a conductive ring member; a half-coil comprising a first group of strands comprising more than one strand stack and a second group of strands comprising more than one strand stack; two strand group clips secured, respectively, to said first and second groups of strands to bind said stacks within said strands together, said clips being electrically conductive; a first conductor member affixed at a first end to said strand group clip of said first group of strands; a second conductor member affixed at a first end to said strand group clip of said second group of strands; and means for electrically connecting a second, opposite end of said first conductor member and a second, opposite end of said second conductor member to said conductive ring member, whereby a phase connection is achieved which is less labor-intensive to install and more durable than connectors heretofore known. - View Dependent Claims (8, 9, 10, 11)
