Abstract

A method of forming a conductive coil for window-type transducer core 10 utilizes plastic carrier 12 having a series of conductive lands 14 printed on it. The carrier with the conductive elements is inserted through and wound around core 10. The ends of lands 14 are offset to match the ends of adjacent lands and are bonded together by soldering, welding, or the like to form a continuous helical coil. Taps can be provided by having one or more lands longer than the other so as to protrude and provide a terminal. This arrangement can also be used for multielement transducer assemblies. A single plastic carrier having the necessary number of sets of conductive lands to match the number of cores can be inserted through a stack of cores. The ends of each set of lands can then be bonded to form a separate coil for each core.

The ends of lands 14 are offset to match the ends of adjacent lands and are bonded together by soldering, welding, or the like to form a continuous helical coil. Taps can be provided by having one or more lands longer than the other so as to protrude and provide a terminal.

This arrangement can also be used for multielement transducer assemblies. A single plastic carrier having the necessary number of sets of conductive lands to match the number of cores can be inserted through a stack of cores. The ends of each set of lands can then be bonded to form a separate coil for each core. Bucking coils can be formed on adjacent elements of a multicore transducer to eliminate crosstalk and interference.
