  • Publication number: 20230291089
    Abstract: Disclosed is a radome structure for vehicle-mounted radar devices, in which a planar heating element 2 is laminated and fixed onto a substrate 1 of the radome, a local recess 3 is provided so as to protrude from the substrate 1, a connecting body 4 for electrically connecting an electrode of a heater wire 21 of the planar heating element 2 to a power supply line 5 to the planar heating element 2 is accommodated in the recess 3, and the recess 3 is filled with an insulating resin 6 so as to embed and seal the connecting body 4. It is possible to simplify a connection structure and a waterproof structure of a connecting portion for electrically connecting the heater wire and the power supply line of the radome, and reduce the manufacturing cost of the radome structure having a snow melting function.

  • Publication number: 20180115099
    Abstract: A board-to-board connector includes a male connector and a female connector. The female connector includes: a tubular part that includes a wall disposed in a tubular form along the thickness direction of FPC; and a spring that includes one end extending in an orthogonal direction orthogonal to the thickness direction of the FPC and the other end contiguous to the one end and urged toward the wall by the one end, the spring being disposed in the tubular part. In the female connector, a contact is disposed on the wall of the tubular part, while a contact is disposed on the other end of the spring so as to be opposed to the contact. In the state where the female connector is fitted into the male connector, the contact clamps a protruding terminal with the contact through the restoring force of the spring.

  • Patent number: 9614296
    Abstract: A conductive terminal includes: a connection terminal; a cylindrical body; and a contact piece housed in the cylindrical body. The cylindrical body includes a top plate. A pair of holes is opened through the top plate from both sides of a projection of the contact piece. A jig for applying force to the projection can be inserted into the cylindrical body via the pair of holes. The pair of side plates are provided with a catching unit that catches the contact piece, the projection of which is pressed onto the mounting surface to restrain movement thereof.

  • Patent number: 9583858
    Abstract: A connector terminal includes a conductive bar-shape member, a plurality of concavities each formed as a groove provided in an outer circumference of the bar-shape member, extending in a lengthwise direction of the bar-shape member, and spreading toward an opening from a bottom, and a convexity formed between the adjoining concavities. A first surface is formed on the bottom of the concavity. A second surface and a third surface that form different inclination angles relative to a depthwise direction of the concavity are alternately formed on an internal wall surface of the concavity from the bottom toward the opening.
