Abstract:
The present invention related to a method for mechanically and electrically connecting an electric wire to a terminal element and to a terminal assembly comprising a terminal element and at least one electric wire that is mechanically and electrically connected to the terminal element. For improving such method and terminal assembly, the method comprises the steps of arranging a connecting portion of the electric wire substantially parallel to the an entrance surface of the contact opening; and connecting a joining section of the connecting portion with the contact opening by plastically deforming a lateral cut of the joining section. The terminal assembly includes a terminal element having at least one contact opening, and at least one electric wire that is mechanically and electrically connected to the contact opening, wherein a connecting portion of the electric wire that is located outside the contact opening runs substantially parallel to an entrance surface of the contact opening, and wherein a joining section of the connecting portion is plastically deformed into and thereby non-positively connected to the contact opening.
