Abstract
An improved high voltage generating device such as a fly back transformer or the like which includes a first casing open at one side face thereof and accommodating therein high voltage electrical components, a second casing which is mounted in a cut-out portion formed in a side wall of the first casing and open at its one edge, and an electrically insulating material filled in a space within the first casing. In the above high voltage generating device, undesirable leakage of insulating material between a cut-out portion of a casing and a high voltage variable resistor during its injection into the casing is advantageously prevented without necessity for employing extra parts such as packings, etc., and thus the assembly work is simplified, with consequent reduction in cost.
Claims9
A high voltage generating device which comprises a first casing open at one side face thereof and accommodating therein high voltage electrical components, a second casing which is mounted in a cut-out portion formed in a side wall of said first casing and open at one edge thereof, and an electrically insulating material filled in a space within said first casing, said first casing being provided, along its entire peripheral wall adjacent to said cut-out portion thereof, with a fitting groove extending from said one open side face towards the bottom portion of said first casing and tapered so as to be narrowed at the side of said bottom portion, said second casing being formed with a wire-like protrusion provided adjacent to the peripheral edges thereof on its one surface in a position corresponding to one side face of said cut-out portion defining said fitting groove of said first casing, said peripheral edges of said second casing which include said wire-like protrusion being arranged, in thickness thereof, to be larger to a certain extent, than widths of said fitting groove at portions thereof corresponding to respective portions of said fitting groove.
