  • Publication number: 20240388044
    Abstract: A high current terminal for electronic circuit protection includes: a first sectional terminal into which a current flows from the outside; a second sectional terminal transmitting a current flowing inside through the first terminal to the outside; and an element coupled between the first sectional terminal and the second sectional terminal, wherein the element disconnects the first sectional terminal and the second sectional terminal by melting when a current exceeding a preset condition flows inside through the first sectional terminal, and is formed to have a thickness that is equal to or less than thicknesses of the first sectional terminal and the second sectional terminal.

  • Patent number: 9735551
    Abstract: A surge absorber and a manufacturing method thereof are disclosed. Since a ceramic material with excellent mechanical strength is used to form a ceramic tube and the ceramic tube is joined to sealing electrodes by use of brazing rings according to the method of manufacturing the surge absorber, durability of the surge absorber is considerably improved. Since the ceramic tube is completely sealed, the surge absorber may be stably used at a high voltage.
