Title: Battery booster cable assembly
Abstract:A battery booster cable assembly includes a pair of booster wires. Each booster wire has first and second ends with a first pair of battery clamps attached to the first ends of the booster wires and the second pair of battery clamps attached to the second end of the booster wires. A switch selectively electrically interconnects the first and second ends of one of the booster wires. A voltage detector is responsive to voltage across the switch for determining if the voltage is greater or less than a predetermined value. A red LED indicates when the detected voltage is greater than the predetermined value, while a green LED indicates when the detected voltage is less than the predetermined value. A solenoid-actuated plunger selectively precludes actuation of the switch when the detected voltage is greater than the predetermined value. The switch and the red and green LED's are carried by a housing which includes two portions selectively slidable between first and second positions. In the first position, the switch is open and the LED's are in view, while in the second position the switch is closed and the LED's are hidden from view.

Assignee: Associated Equipment Corporation (St. Louis, MO)
Filing Date:Apr 29, 1982
Application Number:06/372,958
Claims:1. A battery booster cable assembly, comprising:

(c) second battery attachment means connected to the second ends of the booster wires,

(d) indicating means including light means responsive to voltages applied to the booster wires,

(e) switch means connected to one of the booster wires for selectively electrically interconnecting the first and second ends of said one booster wire,

(f) housing means including first and second portions interconnected in a sliding relation, so as to be selectively slidable between a first position and a second position, and

(g) the housing means carrying the switch means and actuating the switch means upon selectively sliding the housing portions between the first and second positions, the switch means being open when the housing portions are in the first position and closed when the housing portions are in the second position.

2. A battery booster cable assembly as defined in claim 1, in which:

(h) the light means is carried by the housing means, the light means being in view when the housing portions are in said first position, and hidden from view when the housing portions are in said second position.

3. A battery booster cable assembly as defined in claim 1, in which:

(h) a voltage-detecting means is responsive to voltage across the switch means for determining if said voltage is greater or less than a predetermined value, and

(i) a lockout means is actuated by the voltage-detecting means for preventing selective movement of the housing portions from the first to second positions when said detected voltage is greater than said predetermined value.

4. A battery booster cable assembly as defined in claim 3, in which:

(j) the lockout means is a solenoid-actuated plunger.

5. A battery booster cable assembly, comprising:

(a) a pair of booster wires, each booster wire having first and second ends,
