Open the CIPO recordAbstract From the Canadian patent
A clamping mechanism for mounting a circuit condition monitoring device to electrical cables of various diameters includes a core member comprising a plurality of laminations arranged in a generally rectangular configuration. A spring spanning the core member is anchored at one end to the core at a point near the housing of the monitoring device and at the other end is attached to a bridging member affixed at the opposite end of the core near the housing. This allows the spring to expand less as it transverses the bridge in order to accommodate different power cable diameters.

Why it's free to use
- Filed September 29, 1998 and granted January 1, 2002. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended September 29, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 29, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
