ABSTRACT:
BACKGROUND OF THE INVENTION
This invention relates to electric storage batteries, and particularly to a quick connection and mounting of the battery within a holder.
Most present automotive batteries used for starting the engines use the familiar SAE-type lead post terminals. Such terminals usually require a lead ring-type connector on the cable. The lead ring is typically tightened by means of a nut and bolt, thereby requiring tools for installation and resulting in a relatively difficult and inconvenient installation process.
It is the object of this invention to provide a mounting base for an engine starting battery in which the battery may be easily connected to the vehicle ignition system and snapped into the base without the use of tools. The mounting base completes the necessary electrical contact of the battery terminals to the electrical system of the automobile and also securely mounts the battery.
SUMMARY OF THE INVENTION
According to the invention, a battery mounting base has an upright at one end with two spring loaded contacts that mate with the terminals of a battery when the battery is inserted in the base. The mounting base has a locking mechanism that aligns the battery with the contacts and firmly anchors the battery without the need for further hold down hardware. A release lever on the base allows the battery to be withdrawn from the base.
The invention also resides in the combination of a battery and a mounting base in which the battery has a housing with a pair of spaced terminals extending from one face and the base includes a floor with an upright at one end having a pair of spaced contacts adapted to engage the terminals. Interengaging members on the battery housing and the base releasably lock the housing in the base.
The mounting base is particularly useful in mounting thin metal film batteries. The spring loaded contacts insure a low resistance connection to the battery terminals so that available power to the ignition system is maximized.
The present invention eliminates the requirements for tools, increases the convenience for the installer, and decreases the likelihood of minor hand injuries or other injuries resulting from scraped or bruised knuckles, wrist strains, or electrical arcing caused by unintentional short circuiting of battery terminals by wrenches or other tools.
The foregoing and other objects and advantages of the invention will appear in the detailed description which follows. In the description, reference is made to the accompanying drawings which illustrate a preferred embodiment of the invention.
