  • Patent number: 8817576
    Abstract: A distance sensor for vehicles is provided which includes a sensor device and an electric connector for an electrical connection between the sensor device and a mating connector. The connector includes at least one first terminal pin and at least one second terminal pin. The first terminal pin has a first section leading to the sensor device and a second section extending toward an inlet opening of the connector. The second terminal pin has a first section leading to the sensor device and at least two branched second sections extending toward the inlet opening of the connector. Specifically, the second terminal pin is shaped to provide two-pin plugs, thereby permitting the size of the connector to be reduced, which facilitates ease of installation of the distance sensor to, for example, a bumper of the automotive vehicle.

  • Patent number: 8411532
    Abstract: A distance sensor equipped with a mount for mounting the sensor in a mount hole of a bumper of a vehicle. The mount includes a casing with a sensor holder, a bezel, and a resin-made retainer. The bezel is made up of a cylindrical member joined to the sensor holder and a flange having an outer diameter greater than an inner diameter of the mount hole. The retainer includes an annular base joined to the bezel, a plurality of arms, and a plurality of protrusions. The protrusions extend from ends of the arms radially outward of the base and serve to establish a snap-fit on a peripheral edge of the mount hole, thereby nipping a wall of the bumper between the protrusions and the flange tightly to secure the distance sensor to the bumper.
