Open the CIPO recordAbstract From the Canadian patent
A removable connector operable to be inserted between a main cable carrying seismic information and a box connector of a remote acquisition module. The removable connector is adapted to isolate any forces arising in the main cable from the box connector of the module. The removable connector is removably secured to the remote acquisition module by a pin which extends through the housing of the removable connector and a bracket mounted to the module. The pin transfers the cable forces to the remote acquisition module and substantially isolates the box connector from such forces thereby extending the life of the box connector.

Why it's free to use
- Filed September 28, 1995 and granted April 3, 2001. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended September 28, 2015.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 28, 2017.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
