Abstract
Abstract A battery-connection system for a battery having a pair of battery terminals of opposite polarity and positionable in either of two reversed positionings relative to distribution means. The distribution means includes a pair of spaced electrical terminals of particular and opposite polarity electrically connected with a unit to be powered. A carrier interpositioned between the battery and distribution means including a first pair of electrical contacts in singularly-polarized electrical contacting engagement with the respective battery terminals and a second pair of spaced electrical contacts electrically connected with respective ones of the first pair of contacts for singularly-polarized electrical contacting engagement with the respective pair of distribution means terminals. Each contact of the carrier second pair is of opposite polarity to the other, and comprises a set of plural alternate contacts of the same polarity. These alternate contacts of each set are relatively positioned such that the polarity of the connection between the battery terminals and the pair of distribution means terminals is constant for either of the reversed positionings of the battery. Where the battery includes a pair of differently-keyed battery terminals for establishing polarity, the first contacts on the carrier are similarly keyed for the correct mating engagement with the battery terminals and may be structured to mechanically join the carrier with the battery.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
192 words
A battery-connection system for a unit to be powered wherein the battery is positionable in either of two reversed positionings relative to a distribution means and having a pair of battery terminals of opposite polarity similarly reversed in said two reversed positionings respectively, comprising: a said distribution means including a pair of spaced electrical terminals of particular and opposite polarity electrically connected with a unit to be powered; and a carrier means including a first pair of spaced electrical contacts for singularly-polarized, electrical contacting engagement with said battery terminals respectively, and a second pair of spaced electrical contacts electrically connected with said first pair of contacts respectively for singularly-polarized electrical contacting engagement with said pair of distribution means terminals respectively, each contact of said second pair of contacts being of opposite polarity to the other and comprising a set of plural alternate contacts of the same polarity, the said alternate contacts of each set being relatively positioned such that the polarity of the connection between said battery terminals and said pair of distribution means terminals is constant for either of the two reversed positionings of the battery relative to said distribution means.
Claim 2
Dependent Claim
192 words
A battery-connection system for a unit to be powered wherein the battery is positionable in either of two reversed positionings relative to a distribution means and having a pair of battery terminals of opposite polarity similarly reversed in said two reversed positionings respectively, comprising: a said distribution means including a pair of spaced electrical terminals of particular and opposite polarity electrically connected with a unit to be powered; and a carrier means including a first pair of spaced electrical contacts for singularly-polarized, electrical contacting engagement with said battery terminals respectively, and a second pair of spaced electrical contacts electrically connected with said first pair of contacts respectively for singularly-polarized electrical contacting engagement with said pair of distribution means terminals respectively, each contact of said second pair of contacts being of opposite polarity to the other and comprising a set of plural alternate contacts of the same polarity, the said alternate contacts of each set being relatively positioned such that the polarity of the connection between said battery terminals and said pair of distribution means terminals is constant for either of the two reversed positionings of the battery relative to said distribution means.
Claim 3
Dependent Claim
33 words

Claim 11
Dependent Claim
31 words
The battery-connection system of claim 1 wherein the battery is of generally rectilinearly-shaped geometry and said battery terminals are on one end of the battery in non-concentric relationship with one another.
Claim 12
Dependent Claim
59 words
The battery-connection system of claim 10 including battery-holding means having a battery compartment therein, said distribution means being fixedly positioned at one end of said battery compartment to comprise one end wall thereof, the opposite end wall of said battery compartment being positioned to urge the battery and said carrier means and said distribution means into mutual operative engagement.
Claim 13
Dependent Claim
33 words
The battery-connection system of claim 11 wherein said distribution means terminals comprise a pair of spring-contacts for biased engagement with a respective pair of the alternate contacts of said second pair of contacts.
Claim 14
Dependent Claim
30 words
The battery-connection system of claim 12 wherein said battery-holding means is configured to accommodate sliding access of the battery to the battery compartment through one side of the battery compartment.
