Description

Coil frame and transformer with this coil frame in which the first coil is reliably insulated from the second coil

Background of the Invention

The present invention relates to a coil frame, and more particularly to a transformer equipped with such a coil frame.

The conventional coil frame includes a sleeve, several partition plates, and first and second end plates. Such a sleeve is provided with a perforated inner surface. The dividers are attached to the sleeve at regular intervals from each other and are perpendicular to the sleeve. The first and second end plates are attached to both ends of the sleeve at the same intervals as the dividers at both ends, respectively.

Conventional transformers include a coil frame, first and second coils wound around the coil frame, a magnetic core attached to the coil frame, and first and second set connectors. These first and second coils are wound around a sleeve between the dividers and are connected to the first and second set connectors, respectively.

In such a conventional transformer and coil frame, it is almost impossible to reliably insulate the first coil from the second coil by means of a divider. This is because the dividers do not surround the first coil or the second coil. Also, as long as the dividers are perpendicular to the sleeve and the height is high, the height of the coil frame and the transformer is increased.
