The invention refers to an electrical connection (10) comprising a bushing (12) having a geometric central axis (14), an electrical conductor (16) passing through said bushing (12) along the geometric central axis (14), and an insulating layer (18) electrically insulating said bushing (18) from said conductor (16). It is suggested that the bushing 12, the insulating layer (18) and the electric conductor (16) are pressed together, preferably during a rotary forging process, in order to achieve a mechanical cold transformation.

A terminal connection structure includes a first terminal, a second terminal, and a terminal guide. The first terminal includes a held portion. The second terminal includes a plate-shaped base portion, a pair of holding portions projecting from one end of the base portion to hold the held portion from both sides, and a plate-shaped bridge portion projecting from the other end of the base portion in a direction crossing relative to the base portion. The terminal guide includes a guide hole having one end at which the first terminal is disposed, and the other end from which the second terminal is inserted.
