Transformer with closed conductive loop

摘要

A transformer, particularly for use in intrinsically safe systems, has separate first and second magnetic cores mounted in wells in a one-piece elastics housing which serves both as a housing and to electrically segregate the cores. Passing through the housing and through the cores is a wire loop which is turned back and joined outside the housing so as to link the two cores electromagnetically. The cores are preferably toroidal cores carrying windings.
