  • Patent number: 10770819
    Abstract: Provided is a low-cost and high-reliability connector in which a guide member integrally formed with a housing guides a leg part of a terminal so that the position of the leg part of the terminal can be stabilized with a simple configuration. A connector includes a housing; terminals that include leg parts to be connected to a board, and are integrally formed with the housing; and guide members that are integrally formed with the housing and guide the leg parts. The leg parts each include: a horizontal part that protrudes toward a back side from the housing; a vertical part with a part around a distal end to be connected to the board; and a curved part through which the horizontal part and the vertical part are connected with each other. A gap is provided between a back surface of the guide member and a front surface of the vertical part.

  • Patent number: 10483703
    Abstract: A connector is provided which has a main body, a contact part, a tail part, and a plurality of terminals. The main body is made of an insulating material formed in a columnar shape extending in an inserting and extracting direction with a counterpart connector. The plurality of terminals are made of a conductive material loaded in the main body. The terminals are arranged around an axial wire extending in the inserting and extracting direction of the main body so that the position of the tail part forms a polygon in a plan view in a direction perpendicular to the axial wire. The main body includes a tail holding part extending in an axial wire direction. The tail part of each adjacent terminal is exposed at a different position in the axial wire direction in the tail holding part.

  • Patent number: 9989150
    Abstract: A belt-type continuously variable transmission is equipped with a belt wrapped around across a primary pulley and a secondary pulley, and a CVT control unit for controlling pulley hydraulic pressures to the primary pulley and the secondary pulley. The CVT control unit determines whether an operating state is a driving state where the direction of an input torque inputted to the belt-type continuously variable transmission is from a driving source or a coasting state where the input torque direction is from drive road wheels. The pulley hydraulic pressure for the input torque for when it is determined that the operating state is the coasting state is set higher than the pulley hydraulic pressure for the input torque for when it is determined that the operating state is the driving state, thereby suppressing a slippage of the belt.
