  • Patent number: 9523592
    Abstract: A rotation detector includes a sensor element, a signal wire connected to the sensor element, the signal wire transmitting the rotation detecting signal, a sensor coating portion integrally coating the sensor element and an end of the signal wire connected to the sensor element, and a sensor attachment member at least supporting a part of the sensor coating portion and a part of the signal wire. The signal wire includes a curved portion. The sensor attachment member has a surface provided with depression portions. When the sensor attachment member is being molded, the depression portions are engaged with a pair of guide members which protrude toward the curved portion in a cavity of a molding die in a direction perpendicular to a surface including the curved portion, and the guide members protrude in directions opposite to each other.

  • Patent number: 9244089
    Abstract: A rotation detecting unit is adapted for a rotatable body. The rotation detecting unit includes a rotation detecting part, a signal transmission member, and a main body part. The rotation detecting part detects a rotational state of the rotatable body and outputs a rotation detection signal. The signal transmission member is electrically connected to the rotation detecting part to transmit the rotation detection signal to an external device. The main body part holds at least a part of the signal transmission member and the rotation detecting part. The main body part is integrally molded from thermosetting resin including a joined part obtained as a result of joining together a terminal of the rotation detecting part and the signal transmission member, the part of the signal transmission member, and the rotation detecting part. The main body part includes a recess at a region corresponding to the rotation detecting part.

  • Patent number: 8941374
    Abstract: A rotation detector component detects a rotational state of a rotor and sends a rotational detection signal. A signal transmission component is electrically connected with a lead frame of the rotation detector component to transmit the rotational detection signal to an external device. A body portion holds the rotation detector component and a part of the signal transmission component. The body portion is integrally molded of a first resin to cover a joint portion between the lead frame and the signal transmission component, the rotation detector component, and a part of the signal transmission component. A part of the rotation detector component forms an exposed portion exposed from the body portion.

  • Publication number: 20040150390
    Abstract: A detector for detecting rotational speed of a vehicle wheel includes a detector element disposed in a housing and a lead wire for sending output signals of the detector element to an outside device. An output terminal of the detector element is electrically connected to the lead wire by tungsten inert gas welding. The housing and the lead wire are molded together with a resin material that forms an outer wall of the detector. Since the lead wire and the output terminal are connected by the tungsten inert gas welding, the junction is protected from any damages due to pressure and heat generated in the molding process.
