抗器を接続させている。"Prior art" Conventionally, for example, high-voltage connectors for power supplies of copiers, facsimile machines, printers, etc., need to be manufactured robustly because high voltages of 10, 20, 30 kv, etc. are applied thereto. A fixed resistor is connected between one end of the high voltage electric wire and the electrode sleeve.

に突出させている。For example, in the known example shown in FIG. 11, one end of a fixed resistor 40 is connected to the inner end of a high-voltage power supply wire, and a brass sleeve is connected to the other end of the fixed resistor. A coil spring is connected to the lower end of the copper sleeve, and a part of the inner end of the high-voltage wire, the fixed resistor, and a part of the brass sleeve are buried and molded in an insulating synthetic resin connector body, The coil spring protrudes from a plug fitting recess of the connector body.

増等も避けられなかった。"Problems to be Solved by the Invention" However, in such a high-voltage connector for power supply, a fixed resistor and the brass sleeve are separately provided in the connector main body, so that a considerable space is taken. The connector body becomes large, and there is a risk of disconnection due to molding pressure during molding,
Since the fixed resistor is directly incorporated in the main body, it is directly affected by the molding heat, the resistance value is easily changed, and metal powder is mixed at the time of molding, and between the fixed resistor and the insulated wire. Since the distance is short, the wire may be disconnected, or may not be electrically and mechanically stable. In addition, an increase in processing cost and an increase in weight of the product cannot be avoided.

造法。2. A fixed resistor having one lead connected to the inner end of a high-voltage power supply wire is inserted into a fixed resistor fitting recess of a fixed resistor built-in holder, and the other lead is connected to the fixed resistor. Guiding the conductive spring outward and connecting it to the corresponding portion of the cylindrical portion of the conductive spring by soldering or the like; winding the upper hook ring of the conductive spring around the cylindrical protrusion of the fixed resistor built-in holder. After turning, the straight portion is fitted into the groove for spring fitting, and the middle portion is wound around the small-diameter spring fixing cylindrical lower portion, and the conical lower portion and the spiral projection bottom are removed from the small-diameter spring fixing cylindrical lower portion. Projecting; providing a base of the fixed resistor built-in holder in a cavity of an upper mold, and winding the fixed resistor built-in holder on the lower cylindrical portion for fixing the small diameter spring and the lower portion of the fixed cylindrical shape. Times The conical lower end of the conductive spring and the bottom of the spiral projection are arranged in a cavity of a lower mold, fixed with a core, and after the upper mold and the lower mold are united, melted. Injecting an insulating synthetic resin, removing the mold after the molten insulating synthetic resin is cured, and removing the mold.
