Testing the latching strength of an inserted connector assembly. A customer was experiencing intermittent communication failures on a logging tool in high temperature steam injection wells. The point of concern was a multi pin connector assembly within the tool joint. Each individual pin connector latched into a connector block. The individual pin connectors had beryllium copper cantilevered barbs that snapped into an internal shoulder within the connector block. The concern was that the beryllium copper was losing strength from exposure to the extreme temperatures. A test program was designed to verify the loss of strength caused by the high temperatures. A force gage was used to the measure the axial force required to strip the latch before and after exposure to high temperatures within the oven. The latch did indeed loose strength and the customer switched to a more expensive molded glass multi pin connector assembly.
