INDUCTANCE COIL (ALTERNATIVES) Russian patent published in 2008 - IPC H01F17/02 H01F5/04 

FIELD: electrical engineering; inductive sensors in measurement technology and inductors for magnetotherapy instruments in medicine.

SUBSTANCE: proposed inductance coil has multiconductor strip-line section, rectangular dielectric box with slits to pass coil conductors, and assembly connecting starting and finishing leads of strip line conductors shifted one pitch apart. Dielectric clasp has jack and pin parts joined together and provided with slits disposed perpendicular to longitudinal axis of clasp. Strip line is passed through slits of jack and pin parts of clasp and its part is brought out on face end of clasp to its rear end; it is folded to form one bifilar loop and tightly fitted to strip line section near jack or pin part of clasp, or it is compressed to form two bifilar loops tightly fitted to strip line sections near jack and pin parts of clasp. Hole is provided in one of two side walls of slit-free box to pass electric cord into box. First leads of cord conductors are connected to contacts of connector cable section. Its second leads entered into box are connected to mentioned assembly leads. As an alternative, flat connector contacts are additionally connected in series with strip line conductors.

EFFECT: enlarged functional capabilities due to ability of varying inside dimension of coil.
