Abstract
Description
- This disclosure is related to an object for use in covering battery terminals. In particular, the disclosure is related to a disposable safety cover used to stop nine volt batteries from coming into contact with a conductive material and creating a low resistance circuit.
- The statements in this section merely provide background information related to the present disclosure. Accordingly, such statements are not intended to constitute an admission of prior art.
- Batteries are known devices which provide portable direct current electrical power for battery powered devices. A nine volt battery is a widely known and widely used battery configuration wherein a positive terminal and a negative terminal are present upon a same top surface of the battery.
- Electrical circuits are known in the art and require that electrical energy can flow in a complete circuit. A battery or a plurality of batteries can be used in a circuit, wherein a battery provides a voltage potential or voltage rise in the circuit. For a given voltage potential, a current in the circuit can be determined according to the relationship voltage potential equals current times electrical resistance. When resistance is relatively high in an electrical circuit, the current for the circuit is relatively low. When resistance is relatively low in an electrical circuit, the current for the circuit is relatively high. If resistance is very low in a circuit including a battery, the current can get very high. In such a low resistance circuit, the battery supplying the electrical energy to the circuit can heat up significantly to a point where a dangerous thermal event can in certain circumstances be created.
- Nine volt batteries are designed to have very low resistance between the internal components of the battery and the battery terminals. If any conductive piece spans the two terminals of a nine volt battery, e.g. if a piece of aluminum foil is discarded in the same waste container as a partially depleted nine volt battery and touches both terminals, a very low resistance circuit can be created causing a thermal event in the battery.
- Batteries contain chemicals that can be detrimental to the environment if the battery is simply thrown into a landfill. Recycling of batteries has become popular. While a partially depleted battery may include too little voltage potential to continue to be used by a consumer and may be ready to be recycled, the battery still can have enough charge to power an electrical circuit. Consumers wishing to recycle batteries will frequently store used batteries in groups, for example, in a bag or a box, until enough of them have been collected to warrant the effort to take the batteries to a recycling center. A group of nine volt batteries tossed into a bag or a box can accidentally create low resistance circuits.
- A nine volt battery includes terminals exposed on a top surface of the battery and can easily accidentally come into contact with a conductive material. A device is provided for preventing creation of a low resistance circuit by a nine volt battery includes a safety cover configured to securely adhere to at least one of two terminals of the battery, thereby preventing creation of a circuit through the battery.
- One or more embodiments will now be described, by way of example, with reference to the accompanying drawings, in which:
-
FIG. 1 illustrates an exemplary embodiment of a safety cover to be installed to a nine volt battery, in accordance with the present disclosure; -
FIG. 2 illustrates a first embodiment of an exemplary safety cover in cross-section, in accordance with the present disclosure; -
FIG. 3 illustrates a second embodiment of an exemplary safety cover in cross-section, in accordance with the present disclosure; -
FIG. 4 illustrates a third embodiment of an exemplary safety cover, in accordance with the present disclosure; -
FIG. 5 illustrates a fourth embodiment of an exemplary safety cover, in accordance with the present disclosure; -
FIG. 6 illustrates an exemplary safety cover strip including a plurality of separable safety covers, in accordance with the present disclosure; -
FIG. 7 illustrates an exemplary safety cover strip including test strips located to each battery connection, in accordance with the present disclosure; and -
FIG. 8 illustrates an additional exemplary embodiment of a safety cover including an elastic band wrapped around the battery and covering at least one terminal of the battery, in accordance with the present disclosure. - Low resistance circuits can be created by any conductive material spanning the terminals of a nine volt battery. In one example, a piece of metallic waste can come into contact with the terminals. In another example, a metallic casing on one nine volt battery can come into contact with terminals on another nine volt battery. In another example, two nine volt batteries can accidently touch negative to positive terminal, negative to positive terminal.
- A low resistance circuit including a nine volt battery and a piece of conductive material spanning the terminals of the battery can be avoided by preventing contact between at least one of the terminals and the conductive material. A device for preventing creation of a low resistance circuit including a nine volt battery is provided including a disposable safety cover preventing at least one of the terminals of the battery from contacting any conductive material.
- Referring now to the drawings, wherein the showings are for the purpose of illustrating certain exemplary embodiments only and not for the purpose of limiting the same,
FIG. 1 illustrates an exemplary embodiment of a safety cover to be installed to a nine volt battery. Ninevolt battery 10 is illustrated includingpositive terminal 12 andnegative terminal 14, both located upontop surface 15 of the battery.Battery 10 further includes ametallic jacket 16 which includes wrappededge 18 and wrappededge 19.Safety cover 20 is illustrated including abattery connection hole 22 configured to receiveterminal 12 andbattery connection hole 24 configured to receiveterminal 14.Safety cover 20 and the included battery connection holes can include a snap-on design, such that the cover includes a detent feature securingly attaches to the battery to prevent the cover from accidentally falling off. The holes, in one embodiment, can be tapered or constricted at the openings to create a more secure fit.Safety cover 20 can be sold as individual units or can be sold installed to fresh batteries, such that a user can install the old battery to the safety cover from the new battery as part of the replacement process. -
Safety cover 20 can be made from any of a number of non-conducting materials including polymers, wood, recycled paper material.Battery terminals -
FIG. 2 illustrates a first embodiment of an exemplary safety cover in cross-section. An elastic or rubberized safety cover can be configured to receive a nine volt battery by stretching the elastic material and allowing the elastic material to apply a gripping force upon the battery terminals to remain attached to the battery.Battery 10 is illustrated includingterminal 12 andterminal 14.Safety cover 120 is illustrated includingbattery connection hole 122 andbattery connection hole 124.Safety cover 120 is constructed of a rubberized polymer that elastically stretches when a force is applied and recovers to its original shape when the force is removed.Battery connection hole 122 is too small to receiveterminal 12, but as safety cover is stretched or pressed againstbattery 10, the rubberized polymer material deforms aroundterminal 12. Similarly,battery connection hole 124 is too small to receiveterminal 14, but as safety cover is stretched or pressed againstbattery 10, the rubberized polymer material deforms aroundterminal 14. In one embodiment, the battery connection holes can include diameters between 1 mm to 4 mm smaller than the corresponding battery terminal, depending upon the particular rubberized material and the desired snap on and snap off force desired for the safety cover.Terminal 14, the negative terminal of the battery, includesundercut feature 17, and safety covers can include a feature or features to grip to theundercut feature 17. - If the safety cover is made of less elastic or more rigid materials, relatively small holes can be used to create battery connection holes, with an interference fit between the holes and the terminals creating the desired snap on fit of the safety cover to the battery. Such interference fits would depend upon the specific materials and can be designed according to methods known in the art. In one embodiment, the battery cover can be constructed of recycled paper material similar to a paper material egg carton known in the art. Such a recyclable material could include marketing advantages for consumers practicing environmentally sensitive recycling.
