Abstract

Abstract Conductive terminals located within a casing constituted by two separable portions and conductive terminals located outside the casing are interconnected by means of conductors which pass through the casing between the two separable portions. In particular, the invention permits interconnection of detection cells and measuring channels within an X-ray tomographic apparatus while preventing leakage currents, the connecting conductors being insulated with respect to each other and with respect to the casing.
