Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
182 words
A battery power source device comprising a battery cassette, two side-by-side rows of cells connected to each other in series, a recess in said device for accommodating said battery cassette, an insulating separator extending longitudinally within the cassette to engage and separate said two rows of cells, two terminal sockets mounted in longitudinal spaces between said two side-by-side rows of cells; two connecting plates positioned on a first one of the end faces of said cassette and a single connecting plate positioned on a second one of the end faces of said cassette, each of said two connecting plates electrically coupling one of said batteries at said first end to one of said sockets, said single connecting plate electrically coupling said batteries at said second end to each other, a plug electrically connected to said sockets, said plug including a lead-in cord that is adapted to be connected to an apparatus that is to be powered by said batteries; and an envelope containing all of said foregoing elements but not said plug, said envelope being made of a thermo-contractive synthetic resinuous film.
Claim 2
Dependent Claim
182 words
A battery power source device comprising a battery cassette, two side-by-side rows of cells connected to each other in series, a recess in said device for accommodating said battery cassette, an insulating separator extending longitudinally within the cassette to engage and separate said two rows of cells, two terminal sockets mounted in longitudinal spaces between said two side-by-side rows of cells; two connecting plates positioned on a first one of the end faces of said cassette and a single connecting plate positioned on a second one of the end faces of said cassette, each of said two connecting plates electrically coupling one of said batteries at said first end to one of said sockets, said single connecting plate electrically coupling said batteries at said second end to each other, a plug electrically connected to said sockets, said plug including a lead-in cord that is adapted to be connected to an apparatus that is to be powered by said batteries; and an envelope containing all of said foregoing elements but not said plug, said envelope being made of a thermo-contractive synthetic resinuous film.
Claim 3
Dependent Claim
35 words
A battery power source device as claimed in claim 1, in which each of said two connecting plates at said first end has apertures therein positioned in alignment with one extremity of said terminal sockets.
Claim 4
Dependent Claim
22 words
A battery power source device as claimed in claim 1, in which said insulating separator has a substantially x-shaped or H-shaped cross-section.
Claim 5
Dependent Claim
31 words
A battery power source device as claimed in claim 1, in which said plug is supported on a pivoting shaft to facilitate the mounting of the battery cassette into the recess.
Claim 6
Dependent Claim
45 words
A battery power source device as claimed in claim 4, in which said plug is located at one extremity of said recess, while at the opposite extremity thereof there is located a battery cassette retainer for rigidly holding the nonswinging end of the battery cassette.
Claim 7
Dependent Claim
41 words
A battery power source device as claimed in claim 5, in which said battery cassette retainer comprises a hook supported by a resilient member, said hook having a slanted upper surface which slidably engages said non-swinging end of the battery cassette.
Claim 8
Dependent Claim
43 words
A battery power source device as claimed in claim 1, in which teh battery cassette is held in position within said recess with at least one portion thereof spaced from the bottom surface of the recess to allow heat dissipation from the recess.
