ABSTRACT:
A connector for attaching a downhole tool to the end of a tubing string insertable in a wellbore includes a frangible coupling portion having a pin with a predetermined cross sectional area which will fail in tension to separate the connector from the tool if the tool becomes stuck in the wellbore. The pin is disposed in a body member of the connector and interconnected therewith by spring washers to absorb transient shock or impact loads on the tool. The connector includes passages for extending electrical conductors through the coupling portion whereby electrical signals may be transmitted through the tubing string to the downhole tool.
