Open the CIPO recordAbstract From the Canadian patent
An electrical coupling is provided for connecting two coaxial cable housings. The coupling has male and female components which have mating tapered surfaces, such as conical surfaces. Screwing the male and female components together wedges the conical surfaces tightly so that the coupling is resistant to torsional forces that could otherwise cause rotational displacement of the components and lead to unscrewing of the coupling.

Why it's free to use
- Filed June 12, 1996 and granted August 27, 2002. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 12, 2016.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 12, 2018.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
