US 2006/0132275 A1 · Coil form

Abstract

A coil form for forming an inductive element (10) includes a coil body (2) and at least one, for example three separating plates (3). The coil body (2) has an opening (4.1) and includes two portions, a coil portion (6) and a flange portion (7). To put the inductive element (10) together, the separating plates (3) are pushed over the coil portion (6) of the coil body (2). The separating plates (3) divide the surface of the coil portion (2) into a plurality of coil areas where the coil or the coils of the inductive component (10) can be provided, for example by winding an isolated wire around the coil portion (6) in a coil area. The separating plates are made of metal and form another coil of the inductive component. Afterwards, the core of the inductive component is installed by fitting the two E-shaped core parts (11.1, 11.2) together such that the middle leg (13) of each core part (11.1, 11.2) is inserted into the opening (4.1) of the core body (2).

Dependent claims

A coil form for forming an inductive element with a comprising:

a) at least two coils,
b) a hollow coil body for insertion of the core, the coil body being made of an electrically insulating material and
c) at least two separating plates which surround the outer surface of the coil body thereby providing at least one coil area on the outer surface of the coil body for holding a wire that forms a part of a coil,
wherein
d) each separating plate is made of metal, includes an opening for pushing the separating plate over the coil body and a slit for prohibiting short circuits and leakage currents within the separating plate, and in that the separating plate forms a winding of another coil;
e) the separating plates are spaced at a specific plate-distance,
f) where a ratio of the plate-distance to a diameter of the wire is between 1 and 2.
