Abstract
Abstract A disassemblable capacitor mount for large, high power, high temperature ceramic capacitors is disclosed. The capacitor mount allows the capacitors to be mechanically secured to a printed circuit board or other planar surface and allows for good electrical contact to be made with the capacitors to handle high power. The capacitor mount comprises a pair of substantially parallel, spaced-apart conductors, the conductors provided with a plurality of corresponding spaced-apart lateral slots on facing planar sides thereof. A plurality of compressible contactors are disposed within the slots. A plurality of capacitors having opposed electrode ends are disposed between the conductors, the ends positioned within the slots and contacting the contactors. Finally, a rigid mechanism removably fixes the conductors to a planar surface. The conductors compressingly urge against the capacitors. The disassemblable capacitor mount provides a stress relieving, thermal expansion absorbing and heat dissipating structure for securing the capacitors to the planar surface. Specifically, the capacitor mount has a structure which allows faulty capacitors to be readily removed from the capacitor mount and replaced.
