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.
Claims20
A surge protection device comprising:
- a metal terminal disposed between two metal oxide varistors, the metal terminal to extend beyond the metal oxide varistors;
- and
- a spring comprising a flat surface, the flat surface to be coupled to the metal terminal using a soldering paste, the flat surface further comprising an opening to allow air bubbles forming in the soldering paste to be released during the coupling.
A surge protection device comprising:
- a metal terminal disposed between two metal oxide varistors, the metal terminal to extend outside the metal oxide varistors;
- and
- a spring comprising a flat surface, the flat surface to be coupled to the metal terminal using a soldering paste, the flat surface further comprising a bend disposed on one end of the flat surface, the bend to form a gap between the flat surface and the metal terminal.
