ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a side terminal battery connector for lead acid batteries of the flooded and valve regulated type, which is pre-molded, and is integral with the battery top cover.
2. Description of the Prior Art
Battery terminal connectors for lead acid batteries must meet many criteria. These terminals must be capable of being inexpensively mass produced, and easily assembled into battery covers. The terminals must withstand vibration and other forces associated with the attachment and detachment of battery cables, and they must not leak battery acid or gases. One of the most common problems with battery terminals is that the acid in the battery tends to creep between the terminal and the top cover, or the casing, and out of the battery where it comes into contact with the battery cables and other parts of the vehicle, causing corrosion and diminished electrical contact properties.
In small acid capacity batteries such as those used in motorcycles, the loss of acid and gases may lead to premature battery failure.
There have been many solutions proposed to solve acid leak and other problems such as shown in the U.S. patents to West U.S. Pat. No. 2,066,597; Shannon U.S. Pat. No. 3,605,065; Schaefer U.S. Pat. No. 3,413,593; Jennings, et al., U.S. Pat. No. 3,928,079; McEwan U.S. Pat. No. 4,693,948; Anderson, et al., U.S. Pat. No. 4,752,543; Furukawa, et al., U.S. Pat. No. 4,898,796; Uemichi, et al., U.S. Pat. No. 5,208,117; Mix, et al., U.S. Pat. No. 5,326,655; Inkmann, et al., U.S. Pat. No. 5,449,570; and Heiman, et al., U.S. Pat. No. 5,549,986, but none of them are entirely satisfactory.
The battery terminal of the invention does not suffer from the problems of the prior art and offers many positive advantages.
SUMMARY OF THE INVENTION
This invention relates to a battery terminal for lead-acid batteries which includes a main body of L-shape in cross section, which may be encased or not encased in the battery top cover, which terminal has an insert for side attachment of a battery cable, with a projection having a circular opening to receive a post from a battery cell, which may have a circular opening in the top cover for pouring molten lead to join the post and projection when the terminal is encased in the top cover, with the top cover opening closed off by a snap in cover.
The principal object of the invention is to provide a battery terminal for lead-acid batteries that does not leak battery acid or gases, and permits high rate battery discharges.
A further object of the invention is to provide a battery terminal that is pre cast.
A further object of the invention is to provide a battery terminal that is inexpensive to mass produce and easy to assemble into a battery.
A further object of the invention is to provide a battery terminal that is useful with a wide variety of flooded and valve regulated lead-acid batteries.
A further object of the invention is to provide a battery terminal that provides for side attachment of battery cables.
A further object of the invention is to provide a battery terminal that allows the use of a much larger post from a battery cell.
Other objects and advantageous features of the invention will be apparent from the description and claims.
