Description

The invention relates to a plastic component with current-carrying conductor tracks, conductive plastic compounds and methods for producing a plastic component with current-carrying conductor tracks or conductive plastic connections. In particular, the invention relates to a component of a plastic housing for an electric motor in a motor vehicle and a contact disc for an electric motor in a motor vehicle.

State of the art

For motors and other electrical components, the supply of motor and control current often takes place via strip conductors, which are inserted in a plastic housing or in a plastic cover of a housing or encapsulated as inserts. Furthermore, shielding conductor tracks or shielding metal nets can be inserted into plastic components. For electrical or electronic feeders for the contacts of EC and DC motors, as z. As used in the automotive industry, however, this can lead to a variety of problems. This leads, for example, to the use of holding devices during the production in injection molds for inserting printed conductors and electrical components.

These holding devices lead to openings both in the inside and in the outside of plastic housings or plastic lids. Closing the openings leads to higher tool and parts costs. Further, upon exposure to practical conductive liquids, such as salt water, the openings may cause short circuits or leakage current that may occur between tracks having different electrical potentials.

In addition, printed conductors, resilient sheet metal parts, cable lugs and electrical components are often inserted manually into the injection molds used for the production of the plastic components. This also leads to increased production costs.

Furthermore, a problem may arise in that in the molded components, various components such as capacitors, resistors or contact springs are so positively or positively connected to interconnects or other electrical components that a plurality of components are connected to interconnects. This can lead to faulty or defective electrical connections. Therefore, a strict monitoring of process parameters for the production of electrical contacts is necessary to meet the required quality standards. This too leads to increased costs.

Conductor tracks and metal inserts, which are used to shield interference voltages of z. As motors are used, can be connected by fasteners such as resilient sheet metal parts or cable lugs to ground. These fasteners are usually integrated as separate components in the corresponding devices, which can also lead to increased production costs.

Also, electromagnetic components, such as metallic contact discs, which can enable a power supply or a current interruption via a movement, are provided as metal parts, for example stampings, which tend to production errors in the production because they automatically or manually with other components must be connected during the manufacturing process.
