Abstract
The invention is directed to a transformer having a ferromagnetic core with a coil disposed around the core. An insulation layer is disposed over the core and the coil and terminals are connected to the coil. Each of the terminals is formed from cast metal and has a base and a connector. The base is at least partially disposed under the insulation layer. A connector is joined to the base at about a right angle and is located toward the middle of the base.

A transformer comprising:
- a ferromagnetic core;
- a coil disposed around the core;
- a terminal connected to the coil, the coil being formed from cast metal and comprising:
- a base;
- a connector disposed at about a right angle to the base and having opposing first and second sides, the connector being joined to the base such that a first portion of the base extends from the first side of the connector and a second portion of the base extends from the second side of the connector;
- and
- a mount joined to the first portion of the base and being connected to the coil, the mount having a bore that extends along a longitudinal axis of the mount, the axis being disposed at about right angle to the connector.
