Abstract
A highly reliable rectifying device of a vehicle alternator capable of improving the vibration resistance of a diode. A connection lead 33d of a diode 33 included in a rectifying device includes a linear part 33f extended in parallel from a metallic base 33b, and a bent part 33g bent 90° or more substantially like an arc from the linear part 33f. The bending radius R of the bent part 33g is set to a value larger than a separation distance w in a horizontal direction between the terminal of the linear part 33f and the distal part of the connection lead 33d.
Claims2
A rectifying device of a vehicle alternator, the rectifying device comprising:
- a heat sink;
- a circuit board including a connection terminal disposed to be orthogonal to the heat sink, and being disposed in parallel with the heat sink;
- and
- a diode assembly including:
- a metallic base that has a first surface joined to the heat sink,
- an IC chip joined to a second surface of the metallic base,
- a sealing resin body with which the IC chip is molded, and
- a connection lead that has one end electrically coupled to the IC chip and has the other end joined to the connection terminal of the circuit board,
- wherein the connection lead includes a linear part that is extended in parallel to the second surface of the metallic base and bared from the sealing resin body at a root, and a bent part that is bent more than 90° substantially like an arc from the linear part,
- a bending radius R of the bent part is set to a value larger than a separation distance w in a horizontal direction between a terminal of the linear part and a distal part of the connection lead,
- the terminal of the linear part is disposed between the root of the linear part and a vertical line drawn through the distal part of the connection lead, and
- a distance from the bared root of the linear part to a most distal portion of the arc of the bent part is less than twice the bending radius R.
