Terminated inductive coil assembly

Abstract

A toroidal coil (21) having two windings (23, 24) is packaged in a housing (22) which includes a first portion (39) having a cylindrical cavity (41) that extends between an open end and a closed end (43) of the first portion for receiving the coil. The housing also includes two arms (51-51) which extend from the first portion between planes which are substantially coincident with the open end and the closed end of the first portion. Each arm is connected to the first portion and has a free end with internally formed nests (72-72) for receiving contact elements (30-30). Each contact element has aligned, spaced slots (94, 101) at an inner end for terminating a lead of the winding and aligned, spaced slots (107, 111) at an outer end adjacent the free end of the arm in which it is mounted for terminating a conductor (31) of a cable to be loaded inductively. The nests are formed so that the inner and outer slots of the contact element are aligned along an axis transverse of an axis of the cylindrical cavity. The individually housed coil and the orientation of the contact elements facilitate termination of the coil leads and testing prior to the arrangement of a plurality of housed coils in a stack (34). Also, the arrangement of the coils in a stack permits machine connection of cable conductors to the contact elements and assembly of a plurality of the stacks into a load coil case for field use.
