  • Publication number: 20230245803
    Abstract: A surge protection device includes a metal terminal and a spring. The metal terminal is located between two metal oxide varistors, where the metal terminal extends beyond the metal oxide varistors. The spring has a flat surface that is connected to the metal terminal using a soldering paste. The flat surface has a bend on one end which forms a gap between the flat surface and the metal terminal.

  • Patent number: 11043317
    Abstract: Provided herein are protection devices having a tubular ceramic part and a tubular metal oxide varistor (MOV) electrically coupled in series or parallel. In some embodiments, the tubular ceramic part is connected between a first electrode and a second electrode, and the tubular MOV is connected between the second electrode and a third electrode. In some embodiments, the tubular ceramic part and the tubular MOV have a same or similar shape and/or outer circumference. The protection device further includes an enclosure surrounding the tubular ceramic part and the tubular MOV, wherein the first electrode, the second electrode, and the third electrode each have leads extending outside the enclosure. In some embodiments, the tubular MOV includes a central cavity aligned with a central cavity of the tubular ceramic part, wherein the central cavity of the tubular MOV MOV and the central cavity of the tubular ceramic part contain an inert gas.

  • Patent number: 10148079
    Abstract: A circuit protection device includes a metal oxide varistor (MOV), a spring terminal and a thermal disconnect coupling the spring terminal to the MOV. A gas discharge tube (GDT) is coupled to the MOV. The spring terminal is biased such that upon occurrence of an overvoltage condition, heat generated by the MOV melts the thermal disconnect and allows the spring terminal to be displaced away from the MOV, thereby creating an opening circuit.
