Patents Assigned to Oshima Prototype Engineering Co., Ltd.
  • Patent number: 6604365
    Abstract: A thermal link assembly provides thermal connection between a first thermally conductive part to which it is secured, and a second thermally conductive part which is generally disk-shaped and has a peripheral cylindrical surface. The thermal link assembly includes an annular ring made of thermally conductive material, generally in a shape of a revolution with respect to an axis, including an annular base portion to be secured to the first part and a series of contact tongues arranged along the base portion. Each contact tongue has a stem and a head. The stem has i) a longitudinal axis extending generally parallel to the axis of the annular ring, ii) a first longitudinal end connected to the base portion, and iii) a second longitudinal end connected to the head. The head has a contact surface to be in contact with the peripheral cylindrical surface of the second part.
