A first conductor plate is positioned below said insulating layer and a, second conductor plate is positioned on top of said insulating layer. The conductor plates each include extension contacts directed outwardly from the base.

A lead wire is secured to each of the terminal lugs. An additional cover can be installed on top of the wire-jumper assembly to provide safety from accidental contact.

Why it's free to use

  • Filed June 5, 1991 and granted September 14, 1999. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 5, 2011.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 5, 2013.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
