摘要： In a flyback transformer, an insulating cover is interposed between a main body casing and a focusing pack casing. A through-hole is formed through a ceramic resistor accommodated in the focusing pack casing. A fixing hole is formed through the insulating cover in a coaxial relationship with the through-hole. A slider is fixed on a rotatable knob for a variable resistor, which is supported on the focusing pack casing. One of two tongues of the slider is maintained in contact under pressure with a variable resistor of the ceramic resistor, and the other tongue is arranged coaxially with the fixing hole and is maintained in contact under pressure with a wire-shaped output terminal. The terminal is press-fitted in the fixing hole. Another flyback transformer is also disclosed, which comprises a cylindrical holder portion. An exposed portion of a conductor of a voltage output lead wire is formed in an L-shaped bent portion which is press-fitted in the holder portion, whereby the L-shaped bent portion is resiliently held at a basal portion thereof. A conductive rubber is connected to an output terminal. A free end portion of the conductor extends out from the holder portion into the conductive rubber.

摘要： A isolated power supply for protecting electrical devices from transient voltages and currents is disclosed. Specifically, the filter has a toroid and resistor which are used in conjunction with an isolator transformer. The transformer's secondary windings are coupled to the electrical load sought to be isolated. The primary windings of the transformer are tied to an alternating current source with an earth ground lead. The primary shield lead of the transformer is tied to the earth ground lead. The secondary shield lead of the transformer is also tied to the earth ground. A toroid inductor and resistor in parallel are coupled between the secondary neutral lead and the secondary ground lead to shunt off current or voltage spikes. The earth ground is part of a chassis which prevents spark jump insuring the isolation of the power source. The isolator thus provides equal voltage potential between the secondary lead and the primary earth ground at frequencies of less than 1 kHz.
摘要翻译：公开了一种用于保护电气设备免受瞬态电压和电流的隔离电源。具体来说，滤波器具有与隔离变压器结合使用的环形和电阻器。变压器的次级绕组耦合到寻求隔离的电负载。变压器的初级绕组连接到具有接地线的交流电源。变压器的主屏蔽引线与接地线相连。变压器的次级屏蔽引线也绑在地面上。并联的环形电感和电阻耦合在次级中性线和次级接地线之间，以分流电流或电压尖峰。接地是机箱的一部分，防止火花跳跃确保电源的隔离。因此，隔离器在低于1kHz的频率下在次级引线和主接地之间提供相等的电压电位。

摘要： A device for varying an electrode voltage of a CRT of a color TV includes a novel potentiometer arrangement for adjusting the aforesaid electrode voltage. In known voltage-generating devices the electrode voltage is adjusted by a special potentiometer which can handle several kilovolts. According to the invention, the potentiometer track is constituted by a resistive layer (2) situated inside the interior of the output-voltage feedthrough (10) and the wiper is constituted by the end portion of the high-voltage cable (9) which is inserted into a tubular feedthrough portion and which can slide therein in order to adjust the voltage.
