Abstract:
A spark proof booster cable apparatus comprising:a) a housing to house the components;b) four clamps having opposing jaws of a power jaw and a signal jaw whereby the power jaw delivers power current and the signal jaw detects an independent polarity signal;c) two pairs of power cables connecting each power jaw of the said four clamps to the control box;d) two pairs of signal wires connecting each signal jaw of the said four clamps to the control box whereby the combination of a power cable and a signal cable at a jaw pair constitutes a booster cable;e) a set of light emitting diodes connected to optic couplers oriented by an electronic control circuit means, that notify the user of connection status;f) a solenoid assembly controlling the path of power current which is biased into open and closed position by induction generated by the electronic control circuit means;g) a first electronic control circuit means to show that connections between a battery source at opposite ends of a booster cable have been correctly made;h) a second electronic control circuit means to warn the user that connections between battery sources at opposite ends of the booster cables have been incorrectly made;i) a third electronic control circuit means to cause power current to flow through said solenoid assembly if and only if connections between battery sources at all four points of contact at the opposite ends of the clamp and booster cable have been correctly made;j) a fourth electronic control circuit means to terminate power current flow through said solenoid assembly if a connection between a booster cable to a battery terminal has been discontinued.
