Including Threaded Connector Patents (Class 204/297.13)
  • Patent number: 7507319
    Abstract: An anode holder is used to hold an anode in a plating tank. The anode holder includes a bar having a conductive portion connected to a power source, a conductive anode shaft attached to the bar, and an anode connected to the conductive anode shaft. The conductive anode shaft includes an external thread portion provided at an end of the conductive anode shaft, an O-ring, and a step portion provided between the O-ring and the external thread portion. The step portion has a diameter larger than a diameter of the external thread portion but smaller than a diameter of the O-ring. The anode includes an internal thread hole to which the external thread portion of the conductive anode shaft is screwed. The anode also includes a receiving portion for receiving the step portion of the conductive anode shaft in a state such that the O-ring of the conductive anode shaft is brought into contact with an inner surface of the receiving portion.
