  • Torque sensor, wire harness, electric power steering assembly and terminal holder
    Patent number: 7308833
    Abstract: In a torque sensor having lead pins connected to a wire harness, the wire harness includes: a plurality of lead wires; a plurality of connection terminals each having a sleeve mounted around each of the lead pins and a connection portion extended from an outer periphery of the sleeve to be connected with one end of the lead wire; and an electrically insulating terminal holder for holding the plural connection terminals. The terminal holder includes: a sleeve holder portion for holding the sleeves in mutually spaced relation in order to prevent the sleeves from contacting each other; and a connection-portion holder portion for holding the connection portions in mutually spaced relation in order to prevent the connection portions from bending to contact each other.
