Abstract
Abstract The invention provides a safety battery connector which will shut-down the circuit in the case of an over-load and thereby prevent short-circuiting and the like. The safety battery connector incorporates a manually resettable circuit breaker which is connected between the battery and an associated circuit in order to break the circuit in the case of an overload. The device may include an over-heating indicator which is associated with the conducting plate.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
140 words
A safety battery connector for preventing overloading of a battery, comprising: a rigid, electrically conducting support plate; a means for connecting said support plate in electrical conducting relationship around a terminal of a battery; a circuit breaker means; a connector means for connecting said support plate to the circuit breaker means; said circuit breaker means being manually resettable; said circuit breaker means having an output member for providing electrical output connection for an electrically operated device; said support plate providing electrical connection between said terminal and said circuit breaker means and preventing movement of said circuit breaker means relative to the battery, such that short circuiting and overloading is prevented; wherein said support plate comprises a metal body having an aperture for receiving a battery terminal, and having a pair of upstanding side walls to receive said circuit breaker means.
Claim 2
Dependent Claim
140 words
A safety battery connector for preventing overloading of a battery, comprising: a rigid, electrically conducting support plate; a means for connecting said support plate in electrical conducting relationship around a terminal of a battery; a circuit breaker means; a connector means for connecting said support plate to the circuit breaker means; said circuit breaker means being manually resettable; said circuit breaker means having an output member for providing electrical output connection for an electrically operated device; said support plate providing electrical connection between said terminal and said circuit breaker means and preventing movement of said circuit breaker means relative to the battery, such that short circuiting and overloading is prevented; wherein said support plate comprises a metal body having an aperture for receiving a battery terminal, and having a pair of upstanding side walls to receive said circuit breaker means.
Claim 3
Dependent Claim
37 words
A battery connector as claimed in claim 1, wherein said circuit breaker means is a circuit breaker member having a manual reset pushbutton, said circuit breaker member being generally in the form of a rectangular prismatic solid.
Claim 4
Dependent Claim
20 words
A battery connector as claimed in claim 1, further comprising an indicator for permanently indicating overheating of said support plate.
Claim 5
Dependent Claim
38 words
A battery connector as claimed in claim 3, wherein said indicator comprises a shaped memory alloy for irreversibly changing shape above a predetermined temperature and an indicator member fixedly connected to said shaped memory alloy for movement therewith.
Claim 6
Dependent Claim
15 words
A battery connector as claimed in claim 4, wherein said shape memory alloy is nitinol.
Claim 7
Dependent Claim
19 words
A battery connector as claimed in claim 5, wherein said indicator includes a glass tube which is partially opaque.
Claim 8
Dependent Claim
46 words
A battery as claimed in claim 6, wherein said indicator includes a metal base member connected to said glass tube for supporting one end of said shape memory alloy wire fixedly relative to said glass tube and wherein said indicator is mounted on said support plate.
Claim 9
Dependent Claim
122 words
A safety battery connector for preventing overloading of a battery on a boat, comprising: an electrically conducting support plate; said support plate having an aperture for receiving a battery terminal; said support plate having another aperture for receiving an electrically conducting projection from a manually resettable circuit breaker; a manually resettable circuit breaker having two electrically conducting projections; said manually resettable circuit breaker having a manual pushbutton reset; said support plate having a pair of upstanding side walls which receive said circuit breaker; said support plate being relatively rigid; whereby said circuit breaker is supported in fixed electrically conducting relationship to the battery, by the support plate, so as to prevent overloading of the battery due to short circuits and downstream overloads.
Claim 10
Dependent Claim
122 words
A safety battery connector for preventing overloading of a battery on a boat, comprising: an electrically conducting support plate; said support plate having an aperture for receiving a battery terminal; said support plate having another aperture for receiving an electrically conducting projection from a manually resettable circuit breaker; a manually resettable circuit breaker having two electrically conducting projections; said manually resettable circuit breaker having a manual pushbutton reset; said support plate having a pair of upstanding side walls which receive said circuit breaker; said support plate being relatively rigid; whereby said circuit breaker is supported in fixed electrically conducting relationship to the battery, by the support plate, so as to prevent overloading of the battery due to short circuits and downstream overloads.
Claim 11
Dependent Claim
102 words
A safety battery connector as claimed in claim 8, further comprising an indicating means; said indicating means including a glass tube, a metal base fixedly connected to said glass tube, and a shape memory alloy wire spring disposed adjacent to said metal base; an indicator element disposed adjacent another end of said shape memory alloy wire spring; whereby overheating of said support member causes expansion of said shape memory alloy wire spring to an original extended condition so as to push said indicator element to a location where it is visible, so as to indicate permanently an overheating of the support plate.
Claim 12
Dependent Claim
54 words
A safety battery connector as claimed in claim 1, wherein said support plate has a generally annular-shaped end for receiving a battery terminal, and another annular-shaped end for receiving a projection from the circuit breaker means, said another annular-shaped end having a pair of upstanding side walls adapted to snugly receive said circuit breaker.
