Abstract
An electrical circuit assembly having a high voltage component 10 encapsulated in a dielectric potting compound 11, and having a metal casing 13, whereby electrical charge is leaked away, has a deformable material 15 intermediate between the casing and the encapsulation, the intermediate material remaining contiguous with the adjacent portions of the encapsulation, and remaining contiguous with at least some of the adjacent portions of the casing, under normally encountered variations of temperature. The intermediate material may be sufficiently electrically conductive enabling the charge to be leaked away at a rate ensuring that discharges do not occur in spaces within the circuit assembly, for example, the intermediate material comprising a foam of a plastics material with an electrically conductive filler. Whether, electrically conductive, or not, the intermediate material may be resilient; and/or may be adherent. <IMAGE>
