Abstract
An electrical connection assembly for a wireline cutting tool. The electrical connection assembly comprises an electrical connection sub having an upstream end and a downstream end. A pin connector resides within a bore of the electrical connection sub, with the pin connector having a conductive pin. The electrical connection assembly also includes a signal line connector. The signal line connector extends from an upstream end of the electrical connection sub and is in electrical communication with an electric wireline within a wellbore. The signal line connector places the electric wireline in electrical communication with a signal line further downhole. The signal line is associated with a downhole tool. A downstream end of the conductive pin is connected to the signal line. The electrical connection assembly also includes a spring that is wound around the pin and which biases the conductive pin out of a bore of the downstream end of the electrical connection sub.
