u00b0 c ambient temperature is obtained by the favorable arrangement of heat sensitive structural elements in housing frame 1 for example shoulder 8 is provided on the housing bottom for mounting of power transistors which are to be cooled respective printed circuit boards 9 and 9 39 are pivotably mounted on the two longitudinal sides of the housing frame 1 making the servicing thereof readily accomplished by the removal of lids 3 these two printed circuit boards 9 and 9 39 may be for example an amplifier plate and a pulse plate respectively which may be connected together by means of a flexible printed circuit board 10 a shielded preamplifier plate not shown in an opening of the mounting flange may also be provided and may be plugably connected to the amplifier plate 9 by means of a connecting cable or the like snap hooks 14 are provided on shoulders 12 and 13 for supporting the respective printed circuit boards thereon the printed circuit boards 9 and 9 39 can readily be pivoted away from the housing frame 1 by slightly pushing on the snap hooks 14 outwardly biasing them an abutment 15 on the printed circuit boards serves to limit the pivot range of the boards the inner structure of the compact television camera is completely free in such an arrangement in addition the structural parts of the camera are prevented contact with the electrical parts note that upon separation of the plug in connections between the flexible printed circuit board 10 and the two 34 larger 34 printed circuit boards 9 and 9 39 which may be provided for additional fixable modules plug in connections allows for an immediate printed circuit board exchange if necessary without dismantling the entire camera accordingly servicing of the.
