Capacitor module

摘要

A capacitor body is laterally contained in a lower holder, to be then pressed by an upper holder. A lead wire is led from the capacitor body in an axial direction, and then, bent toward a wiring board, thereby forming a leg soldered to the wiring board. The lower holder includes a first holding portion extending outward and having a supporter disposed in a stationary state whereas the upper holder includes a second holding portion extending outward and having a bridge stretched between a pair of elastically deformable arms. The first and second holding portions are urged toward the capacitor body, and therefore, axially hold a part of the leg of the lead wire. This configuration can prevent any breakage of a soldered portion of the lead wire due to vibrations so as to enhance vibration resistance.

主权项

1. A capacitor module comprising:
a capacitor including a capacitor body and a lead wire to be led from one end of the capacitor body; a holder unit having a first holding portion and a second holding portion; and a wiring board having a board surface, to which the holder unit is secured, wherein: the capacitor body is contained in a space surrounded by the holder unit, the lead wire includes a leg bent toward the board surface, the end of the leg of the lead wire is connected to the wiring board, the second holding portion urges the leg of the lead wire toward the capacitor body, and the first holding portion and the second holding portion apply a pressing force to a part of the leg of the lead wire in an axial direction of the capacitor.
