2. Description of the Invention
Vehicle “jumper” cables are well known for “jump starting” or “boosting” undercharged vehicle batteries, such as cars, motorcycles, boats, etc. “Jump-starting” involves transferring electrical energy from a charged battery to an undercharged or discharged battery so that the electrical starter can be operated to turn over an engine. The jump start may be supplied from (1) a second vehicle with a fully charged battery; (2) an A.C. battery charger which may be switchable between a trickle charge mode and a high amperage starting mode; and (3) a battery booster having a rechargeable battery which may be used for jump starting a vehicle or as a D.C. power supply for twelve volt accessories. Once the engine on the vehicle having the undercharged or discharged battery is started, the vehicle can then begin generating its own power using its generator or alternator and the cables are then removed.
Motorcycles, all-terrain vehicles, snowmobiles, jet-skis, as well as a host of other larger type vehicles such as automobiles, semi-tractors, farm tractors, trucks, cargo and passenger vans, are equipped with batteries that are generally inaccessible to jumper cables. That is, substantial effort must be expended to remove obstructing structures (such as a seat) to reach the battery terminals in order to connect jumper cables to the battery terminals. In addition, it is commonly understood that the standard lead-acid batteries widely used in automotive vehicles produce highly volatile vapors, which can ignite upon the presence of a spark. When deenergized batteries are coupled to an energizing battery source (such as another vehicle), an electrical spark is generated, possibly causing an explosion, which may lead to damage, injury, or death.
Several attempts have been made in the prior art to attain easy access to the non-easily accessible battery of modern automotive vehicles, however, no other device appears to codify the aspects of safely and unmistakingly connect a deenergized battery to a charging source.
None of the above inventions and patents, taken either singly or in combination, is seen to describe the instant invention as claimed. Thus a jumper cable system, jumper cable system kit, and battery charging system solving the aforementioned safety problems is desired.
The invention is directed to vehicle jumper cables, and to a battery charger having a connector, which is attachable to the jumper cables. In particular, the inventive cable includes a hermaphroditic connector that ensures proper polarity when the cable is connected either to another vehicle or other vehicle battery, or to the battery charger.
Moreover, the inventive cable can be provided in a kit form to include a first cable section connected permanently at one end to the terminals of a vehicle battery and having a hermaphroditic connector at its opposite end, a second cable section equipped with a hermaphroditic connector at one end and clamps at its opposite end for connecting to the terminal posts of a standard post-type battery, and a third cable section equipped with hermaphroditic connectors at both ends for connecting the first and second cable sections, e.g., as for boosting a vehicle battery from a car battery or for boosting one vehicle from another vehicle equipped with the same cable section. Thus the j ump-starting any currently marketed vehicle has become a labor-intensive activity.
The present invention reduces or removes the labor-intensive aspect of jump-starting vehicles by providing a readily connectable modular jump starting cable, one part of which is permanently installed on the vehicle and having at least one other part that connects the vehicle in distress to the power-supplying vehicle, e.g., to a battery of another passenger vehicle similarly equipped with a permanently installed cable part, or to a non-similarly equipped vehicle with the appropriate connector, or battery charging device. Furthermore, the inventive cable is provided with hermaphroditic connectors that ensure proper polarity when connected.
Additionally, the risk of damage, injury, or death reduction due to the highly volatile environment of conventionally automotive vehicular battery jump-starts is accomplished by providing the remote cable connections using the hermaphroditic connector so that when the cables are connected, any arcing is produced internally of the connectors, away from the generally vicinity of the batteries where the explosive vapors may be present. Also, a safety factor encompassed in the present embodiments is a fusing link to prevent over current from causing damage to either the deenergized battery of the energizing battery source. The fusing link is provided in at least one cable conductor, and causes an open circuit if the electrical parameters exceed a predetermined operational limit.
The aspects of the present invention will become readily apparent upon further review of the following specification and drawings.
Similar reference characters denote corresponding features consistently throughout the attached drawings.
The present invention is directed to a multi-part jumper cable for boosting the battery of a vehicle or for charging a vehicle battery using hermaphroditic connectors. The jumper cable system and battery charging system of the present invention are used by a myriad of vehicles, including motorcycles, all-terrain vehicles, snowmobiles, jet-skis, as well as a host of other larger type vehicles such as automobiles, semi-tractors, farm tractors, trucks, cargo and passenger vans, all of which utilize an electric battery source for starting an internal combustion engine.
The permanently installed cable section 12 includes two electrical cables 32 color-coded to distinguish between the positive cable (typically red in color) and the negative cable (typically black in color), so that a person using the cable will maintain proper polarity during use, i.e., when “jumping” or “boosting” the deenergized battery. However, it is well known in the art that the specific color coding is solely arbitrary, so long as the two colors are individually distinguishable from each other.
The housing 90 defines a storage compartment for the second and third portions, 14 and 16. Depending upon the type of vehicle, the storage compartment may be located under the seat as shown. Alternatively, the storage compartment may be elsewhere, such as to the rear or either side of the seat. In other words, the storage compartment
The second portion 14 of the multi-part jumper cable has first and second ends including hermaphroditic connectors, 42 and 48, respectively, and a fuse 50 intermediate the two ends on one of the two cables, generally the positive cable 22, the rating of the fuse should be on the order of 30 amperes. It, is noted that the fuse is disclosed in the second section 14, however, it is well within the purview of the scope of the embodiments of the invention, that the fuse may be in any one or more of the segments. In this manner, the overall safety features would be a self-backup variation on the use of a defective fuse having an improper rating.
The third portion 16 of the jumper cable is provided at one end with a hermaphroditic connection 46. The opposite end of the third portion 16 of the jumper cable has positive and negative cables, 36 and 38, respectively, and terminates in alligator type clamps 72 and 74 which are adapted for attachment to the terminal posts of a post-type charging battery, such as the type commonly used on passenger vehicles.
As seen in
When the battery 80 is undercharged and requires a “jump” or a “boost” from another battery, such as from a car battery, the vehicle is placed in relative proximity to the car (or other vehicle). Jumper cable section 16 is removed from the storage compartment 90 and clamps 72 and 74 are attached to the respective positive and negative terminal posts of the post-type charging battery. Then cable section 14 is removed from the storage compartment and one end (i.e., either connector 42 or 48) is connected to connector 40 of the first section and the opposite end (i.e., remaining connector 48 or 42) is connected to connector 46 of the second section, thereby completing the boosting circuit.
Hermaphroditic connectors 40 and 42 may be any known type of hermaphroditic connector in which the connectors are identical, and which can only be connected in a manner in which the polarity is ensured, i.e., in which the positive terminal of the fully charged battery is directly connected with the positive terminal of the undercharged battery and the shape of the positive terminal on each connector is identical. Preferably the hermaphroditic connector is of a type exemplified by the connector taught in U.S. Pat. No. 4,963,102, previously incorporated herein. It is noted that although the reference teaches a three-conductor cable, the same connector is used herein for connecting a two-connector cable, i.e., a cable having a positive and a negative cable corresponding to the positive and negative poles of a vehicle battery.
On the positive cable wire 22 a fuse 52 is provided. The fuse is contained in its own housing 50 with a protective cap 54. The fuse is preferably a thirty ampere (30A) blade fuse that corresponds with the wire gauge size capable of “jumping” batteries, e.g., ten gauge AWG.
Thus, the second section 14 may be used either to connect a first jumper cable section 12 fixed to the battery of the vehicle receiving the jump start to a another first jumper cable section 12 attached to the charging battery on a second vehicle, or as an extension cable between the first jumper cable section 12 and third jumper cable section 16 to extend the length of the jumper cable when charging from a passenger car or other vehicle. A general length of the cable portions 12 and 16 should be approximately 3 feet, while cable portion 14 has general length of approximately 6 feet.
When two vehicles are equipped with a 3-piece kit as shown in
The jumper cable kit may be provided with as little as two parts, for example, the kit may be included as a accessory item for a model vehicle having a permanently connected first section manufactured in the vehicle, as seen in
