Abstract

PURPOSE:To prevent the connection of the primary winding with polarity error by making two lead wires of a high-voltage transformer different in length and installing terminals on a printed circuit board mounted with an inverter circuit. CONSTITUTION:Terminals 30, 31 of lead wires 32, 33 of the primary winding 16 of a high-voltage transformer 6 and terminals 35, 36 to connect an inverter circuit 37 are provided on a printed circuit board 34 mounted with the inverter circuit. The terminals 30, 31 are connected to the terminals 35, 36 on the circuit board respectively. The lead wires 32, 33 differ in length, the lead wire 32 is short and does not reach the terminal 36 and can not be connected to it. The primary winding 16 of the high-voltage transformer 6 can be connected to the inverter circuit 37 with no polarity error according to this constitution, thus the life of a magnetron is assured, and the reliability can be improved.
