Abstract
A plastic component with at least one electrical contact element has a plastic body and at least one electrical strip conductor, by which the electrical contact element can be electrically connected. Provisions are made for the plastic component to be manufactured by a combined injection molding and metal casting method, in which the plastic body is manufactured by an injection molding method and the at least one electrical strip conductor is manufactured by a metal casting or metal injection molding method one after another. The component formed last is molded onto the component formed first. Further, a method for manufacturing a corresponding plastic component is described.
Claims16
A plastic component comprising:
- at least one electrical contact element;
- a plastic body;
- and at least one electrical strip conductor, by means of which the electrical contact element can be electrically connected, wherein the plastic component is manufactured according to a combined injection molding and metal casting or metal injection molding method, in which the plastic body is manufactured by injection molding and the least one electrical strip conductor is manufactured by metal casting or metal injection molding the injection molding followed by the metal casting or metal injection molding or the metal casting or metal injection molding followed by the injection molding occur one after another, wherein the plastic body or the at least one electrical strip conductor formed last is molded into the plastic body or the at least one electrical strip conductor formed first, wherein the electrical contact element is a spring bracket contact, which encloses a spring bracket of the plastic body, at which spring bracket a section of the strip conductor is arranged, the spring bracket being formed in one piece with the plastic body, the spring bracket having a freely projecting configuration, the spring bracket being surrounded by a recess passing through the plastic body on all sides except for a side of the plastic body connected to the spring bracket.
A plastic component comprising:
- an electrical contact element;
- a plastic body, the plastic body comprising a through opening;
- and an electrical strip conductor, by means of which the electrical contact element can be electrically connected, wherein the plastic component is manufactured according to a combined injection molding and metal casting or metal injection molding method, in which the plastic body is manufactured by injection molding and the least one electrical strip conductor is manufactured by metal casting or metal injection molding the injection molding followed by the metal casting or metal injection molding or the metal casting or metal injection molding followed by the injection molding occur one after another, wherein the plastic body or the at least one electrical strip conductor formed last is molded into the plastic body or the at least one electrical strip conductor formed first, wherein the electrical contact element is a spring bracket contact, which encloses a spring bracket of the plastic body, at which spring bracket a section of the strip conductor is arranged, the spring bracket comprising only one side fixed to the plastic body, wherein the spring bracket extends into the through opening, the through opening being located between each part of the spring bracket and the plastic body except for the one side of the spring bracket fixed to the plastic body.
A plastic component comprising:
- an electrical contact element;
- a plastic body, the plastic body comprising a through opening;
- and an electrical strip conductor, by means of which the electrical contact element can be electrically connected, wherein the plastic component is manufactured according to a combined injection molding and metal casting or metal injection molding method, in which the plastic body is manufactured by injection molding and the least one electrical strip conductor is manufactured by metal casting or metal injection molding the injection molding followed by the metal casting or metal injection molding or the metal casting or metal injection molding followed by the injection molding occur one after another, wherein the plastic body or the at least one electrical strip conductor formed last is molded into the plastic body or the at least one electrical strip conductor formed first, wherein the electrical contact element is a spring bracket contact, which encloses a spring bracket of the plastic body, at which spring bracket a section of the strip conductor is arranged, the spring bracket comprising a spring bracket end, wherein only the spring bracket end is in contact with the plastic body, wherein the through opening surrounds each portion of the spring bracket except for the spring bracket end.
