Abstract
Abstract A high power flexible connector has a first conductive member adapted for connection to a bushing and a second conductive member adapted for connection to a winding. A plurality of flexible conductors connect the first member to the second member. Mechanically, the conductors provide for independent movement of the bushing with respect to the winding. Electrically, the cables provide a plurality of current paths and produce an electric field when carrying a current. The conductors are arranged such that the induced electric field is uniform.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
139 words
A connector for providing a flexible electrical connection between a winding lead of a winding and a through electrical conductor of a bushing, comprising: a first conductive member adapted for connection to the through electrical conductor; a second conductive member; a plurality of flexible conductors connecting said first conductive member to said second conductive member for mechanically absorbing the motion of said through electrical conductor and for electrically providing a plurality of current paths, said flexible conductors being symmetrically arranged such that a uniform electric field is produced when said flexible conductors are carrying current; a connecting member carried by said second conductive member and adapted for connection to said winding lead, said connecting member being located within a plurality of flexible conductors; and said flexible conductors constituting the only current-carrying conductors connecting said first and second conductive members.
Claim 2
Dependent Claim
139 words
A connector for providing a flexible electrical connection between a winding lead of a winding and a through electrical conductor of a bushing, comprising: a first conductive member adapted for connection to the through electrical conductor; a second conductive member; a plurality of flexible conductors connecting said first conductive member to said second conductive member for mechanically absorbing the motion of said through electrical conductor and for electrically providing a plurality of current paths, said flexible conductors being symmetrically arranged such that a uniform electric field is produced when said flexible conductors are carrying current; a connecting member carried by said second conductive member and adapted for connection to said winding lead, said connecting member being located within a plurality of flexible conductors; and said flexible conductors constituting the only current-carrying conductors connecting said first and second conductive members.
