ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a jumper cable system for jump starting one vehicle from the electrical power of another vehicle.
2. Background of the Prior Art
If a vehicle's battery becomes dead, the usual procedure is to jump start the vehicle from another vehicle. A set of jumper cables are connected between the two vehicles and the live vehicle provides the starting electrical power for the dead vehicle. While this system is tried and true, it is not without its drawbacks. As the jumper cables are attached directly to the battery, the person performing this task is placed in harm's way should the battery explode, a not totally uncommon event. Additionally, the jumper cables can be mis-attached wherein a jumper cable that is meant to be attached to a positive terminal is attached to a negative terminal, or vice versa. Such a situation creates the potential for battery explosion as well as damage to one or both vehicles.
In order to reduce the risk for injury or damage during the jump start procedure, various jumper cable systems have been proposed. However, the proposed systems are unreliable in operation, or are unduly complex to use, or are of relatively complex design and construction resulting in a relatively expensive jumper cable system.
Therefore, there is a need in the art for a jumper cable system that addresses the above-mentioned problems in the art. Such a jumper cable system must reduce the risk of injury to a user resulting from a battery explosion. Such a system must be of relatively simple and straightforward design and construction and must be relatively easy to use. The jumper cable system must be able to prevent cross wiring of the negative and positive terminals of the two batteries to be connected.
SUMMARY OF THE INVENTION
The jumper cable system of the present invention addresses the aforementioned needs in the art. The jumper cable system reduces the risk of injury to a user resulting from a battery explosion by removing the user away from each battery during battery connection. The jumper cable system is of relatively simple and straightforward design and construction and is relatively easy to use. The jumper cable system prevents cross wiring of the negative and positive terminals of the two batteries to be connected.
The jumper cable system of the present invention is comprised of a first receptacle having a first pin with a first cross section attached to the first receptacle, the first pin adapted to be attached to a first battery cable attached to the positive terminal of a first battery. A second pin with a second cross section, lesser than the first cross section, is attached to the first receptacle, the second pin adapted to be attached to a second battery cable attached to the negative terminal of the first battery. A second receptacle has a third pin with the first diameter attached to the second receptacle, the third pin adapted to be attached to a third battery cable attached to the positive terminal of a second battery. A fourth pin with the second diameter is attached to the second receptacle, the fourth pin adapted to be attached to a fourth battery cable attached to the second negative terminal of the second battery. A first jumper cable has a first end and a second end, while a second jumper cable has a third end and a fourth end. A first plug has a first opening electrically connected to the first end of the first jumper cable, the first pin removably receivable within the first opening, the first plug also having a second opening electrically connected to the third end of the second jumper cable, the second pin removably receivable within the second opening. A second plug has a third opening electrically connected to the second end of the first jumper cable, the third pin removably receivable within the third opening, the second plug also having a fourth opening electrically connected to the fourth end of the second jumper cable, the fourth pin removably receivable within the fourth opening. The first pin, the second pin, the third pin, and the fourth pin may all be generally cylindrical and may have a rounded end. The first jumper cable is electrically connected to the first opening by a first socket, the first jumper cable is electrically connected to the second opening by a second socket, the second jumper cable is electrically connected to the third opening by a third socket, and the second jumper cable is electrically connected to the fourth opening by a fourth socket. A first flange having a first opening is attached to the first receptacle and is used to attach the first receptacle to the first vehicle, while a second flange having a second opening is attached to the second receptacle and is used to attach the first receptacle to the second vehicle. The first pin and the second pin are attached to the first receptacle via a first dielectric plate, while the third pin and the fourth pin are attached to the second receptacle via a second dielectric plate.
