Abstract:
1. A tool string for use downhole comprising: a first body having a first signal line in signal communication with a wireline; a second body attached to the first body having a second signal line; a signal line connection assembly coupled between the first and second bodies and that comprises a female connector with an annular contact sleeve, and a male connector that selectively inserts into the female connector, the male connector having an annular contact ring that circumscribes a first booster charge and that is coaxially disposed within the contact sleeve when the male connector inserts into the female connector and is in signal communication with the female connector, so that when the first and second bodies are attached the first and second signal lines are in signal communication through the signal line connection assembly; and a ballistics transfer assembly that comprises the first booster charge and that is coupled on the respective ends of the first and second bodies, so that when a detonation wave in the first body reaches the ballistics transfer assembly to form a ballistic detonation that transmits to the second body and initiates a detonation signal in the second body.
