Abstract

An electric match having electrical leads embedded in flame-producing compound is protected against an accidental resistance across the leads after firing by a length of heat-shrinkable tubing encircling the match body and having a skirt portion extending beyond the leads. The heat of the burning match and an adjacent thermal battery causes the tubing to fold over the end of the match body, covering the ends of the leads and protecting them from molten pieces of the battery.

Solutions for resistance-after-fire problems in an electric match

Conference Heckes, A. A. ; Montoya, A. P.

Current leakage in an electric match after firing is a problem if it drains power that can be used elsewhere or if it induces unwanted fluctuations in other electrical circuits. Two novel techniques are described that significantly reduce the RAF sensitivity of a Ti/KClO/sub 4/-loaded electric match used to ignite the pyrotechnic materials in a thermal battery. In the first technique, a thin (less than 10 ..mu..m thick) film insulator, such as Parylene or SiO/sub 2/, is vapor deposited within the match cavity prior to the loading of the pyrotechnic. The insulator tends to smooth the cavity surface as anmore »« less
