Abstract
Abstract A short-circuitry protection arrangement for an electric battery is disclosed wherein the battery is housed within a housing containing a magnetically switchable switch. The inner housing is insertable into an outer housing which contains a magnet. When the inner housing is inserted into the outer housing the magnet becomes operatively associated with the magnetic switch so that then and then only can power be drawn from the battery.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
140 words
A short-circuiting protection arrangement for an electrical battery, comprising, in combination: a. an electrical battery; b. inner housing means for housing the battery; c. a normally-open magnetically switchable switch arranged in the inner housing means and electrically connectable to the battery; d. outer housing means for housing thE inner housing means, the inner housing means being insertable into the outer housing means; e. a magnet having an associated magnetic field and arranged on the outer housing means for being operatively associated with the switch and closing same when the inner housing means is inserted into the outer housing means; f. terminals mounted on the outer housing means; and g. contact means provided on the inner housing means and outer housing means for connecting the switch to the terminals when the inner housing means is inserted into the outer housing means.
Claim 2
Dependent Claim
140 words
A short-circuiting protection arrangement for an electrical battery, comprising, in combination: a. an electrical battery; b. inner housing means for housing the battery; c. a normally-open magnetically switchable switch arranged in the inner housing means and electrically connectable to the battery; d. outer housing means for housing thE inner housing means, the inner housing means being insertable into the outer housing means; e. a magnet having an associated magnetic field and arranged on the outer housing means for being operatively associated with the switch and closing same when the inner housing means is inserted into the outer housing means; f. terminals mounted on the outer housing means; and g. contact means provided on the inner housing means and outer housing means for connecting the switch to the terminals when the inner housing means is inserted into the outer housing means.
Claim 3
Dependent Claim
81 words
The protection arrangement as claimed in claim 1 wherein the contact means has two contactable bars provided in said inner housing means and two tongues mateable with the bars provided in said outer housing means, said contact means being so arranged in the respective housing means, that when said inner housing means in inserted into said outer housing means, the arms and tongues come into contact with each other before said magnetically switchable switch enters the magnetic field of said magnet.
Claim 4
Dependent Claim
56 words
The protection arrangement as claimed in claim 2 wherein said magnetically switchable switch is connected between one pole of the battery, and one contactable bar of said first contact means and further including at least another magnetically switchable switch connected between the other pole of said battery and the other contactable bar of said contact means.
Claim 5
Dependent Claim
64 words
The protection arrangement as claimed in claim 2 wherein two magnetically switchable switches are connected between one pole of said battery and one arm of said contact means and two magnets are disposed in said outer housing means so that said two magnetically switchable switches are operatively associated with said two magnets when said inner housing means is inserted into said outer housing means.
Claim 6
Dependent Claim
36 words
The protection arrangement as claimed in claim 4 wherein said two contactable bars of said contact means are slidable in said two contact tongues upon insertion of said inner housing means into said outer housing means.
Claim 7
Dependent Claim
48 words
The protection arrangement as claimed in claim 5 wherein an indicator means is connected across the two contactable bars of said first contact means for indicating the operable condition of said battery and an associated window is provided in said second housing means for viewing said indicator means.
Claim 8
Dependent Claim
37 words
The protection arrangement as claimed in claim 6 wherein a soft iron plate means is insertable between said at least one magnetically switchable switch and said at least one magnet for cutting off the operable association therebetween.
Claim 9
Dependent Claim
30 words
The protection arrangement as claimed in claim 7 wherein said inner housing means has said battery, said magnetically switchable switches, said contactable bars and said indicator means integrally cast therein.
