Actuator apparatus and method for manufacturing an actuator apparatus
First Claim
1. An actuator apparatus, comprising:
- a stator device;
a cover device;
a contact device including two lead wires; and
an attenuation device;
wherein;
the stator device and the cover device are joined so that a hollow space is formed between the stator device and the cover device;
the cover device has a first opening, through which the contact device is guided together with the lead wires into the hollow space, so that the contact device runs at least partially in the hollow space and at least partially in the cover device;
a width of the first opening is larger than a combined width of the two lead wires;
the hollow space has no other openings besides the first opening;
the attenuation device is positioned in the first opening so that electromagnetic radiation, which is generated in the hollow space and travels through the first opening, is more highly attenuated by the attenuation device than the radiation would be attenuated without the presence of the attenuation device;
a body of the attenuation device is formed of a material that is dimensioned such that, when the body is positioned in the first opening, the attenuation device attenuates at a frequency of the electromagnetic radiation generated in the hollow space; and
the body of the attenuation device surrounds the contact device while mechanically sealing the hollow space by forming a seal around an inner surface of the first opening.

Abstract
An actuator apparatus is described as having a stator device, a cover device, a contact device and an attenuation device. The stator device and the cover device are joined in such a manner so that a hollow space is formed between the stator device and the cover device. The cover device has an opening, through which the contact device is guided into the hollow space, so that the contact device runs at least partially in the hollow space and at least partially in the cover device. The attenuation device is positioned in the opening in such a manner so that a high-frequency electromagnetic radiation that travels through the opening is more highly attenuated by the attenuation device than the radiation would be attenuated without the presence of the attenuation device.

18. A method for manufacturing an actuator apparatus, the method comprising:
-
joining a stator device to a cover device so that a hollow space is formed between the stator device and the cover device; providing the cover device with an opening, through which a contact device including two lead wires is guided, together with the lead wires, into the hollow space, so that the contact device runs at least partially in the hollow space and at least partially in the cover device; and positioning an attenuation device in the opening so that a body of the attenuation device surrounds the contact device while mechanically sealing the hollow space by forming a seal around an inner surface of the opening, and so that electromagnetic radiation that is generated in the hollow space and travels through the opening is more highly attenuated by the attenuation device than the radiation would be attenuated without the presence of the attenuation device; wherein; the body of the attenuation device is dimensioned such that when the body is positioned in the first opening, the attenuation device attenuates at a frequency of the electromagnetic radiation generated in the hollow space; a width of the opening is larger than a combined width of the two lead wires; and the hollow space has no other openings besides the opening. - View Dependent Claims (19)
