  • Patent number: 11244774
    Abstract: A resistor includes: a first resin protruding part formed in the bottom surface of an exterior material (mold resin body), on an end opposite to a leading side of harness wires along the length of the exterior material near a through-hole piercing an upper surface and a lower surface of the exterior material, and a second resin protruding part, surrounding the circumference of a metal bush embedded in the through-hole and the entire circumference of the resistor substrate. Moreover, a concave part is formed in a region sandwiched between the first resin protruding part and the second resin protruding part.
    Type: Grant
    Filed: May 17, 2019
    Date of Patent: February 8, 2022

  • Patent number: 10896775
    Abstract: A resistor has a structure including a resistor substrate that has paired electrodes and a resistive element formed on an insulating substrate, an insulating exterior material that covers at least the upper and the side surface of the resistor substrate, and harness electric wires that have one end parts connected to the respective electrodes, pass through the exterior material, and extend outside. The paired electrodes are formed on areas other than the end parts of the insulating substrate, and junctions of the end parts of the harness electric wires and the paired electrodes are at positions where creepage distance of insulation from the junctions to the bottom ends of the insulating substrate is a predetermined distance or longer. Such structure provides the resistor having a secured creepage distance of insulation between the conductor parts of the resistor and the metal case in which the resistor is installed.

  • Patent number: 10446297
    Abstract: A power resistor has paired harness electric wires that have one end parts connected to a resistor substrate, and other end parts pass through an exterior material made of insulating resin and extend outward. Crimp terminals, which are means for reinforcing affinity between the coating material of the harness electric wires and the insulating resin, i.e., the exterior material and for maintaining adhesion, are formed on predetermined portions of the harness electric wires. As a result, a short and small power resistor suitable for an in-vehicle environment is provided.
