Abstract
Abstract A battery connector for mechanically and electrically connecting an external battery to a piece of equipment has two plates which mate face to face. On each are complementary, elongated mechanical engagement portions. One engaged first, forms a hinge; the other forms a locking device. Electrical connections are made when the two plates are locked together.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
279 words
A connector unit for connecting two electrical devices together, the connector unit comprising: a first connector element and a second connector element, said first and second connector elements being complementary to one another; said first connector element being for attachment to one of the two electrical devices and said second connector element being for attachment to the other of the two electrical devices; said first connector element including: a first plate; at least one upper claw attached to said first plate; at least one lower claw attached to said first plate; and at least one first electrical connection connected to said first plate; said second connector element including: a second plate having an upper edge and a lower edge; at least one recess defined in said upper edge of said second plate for receiving said at least one upper claw of said first plate to form an elongated hinge means for allowing hinging movement between said first and second plate, said first plate being hangable from said second plate upon receipt of said at least one upper claw by said at least one recess; at least one slot defined in said second plate for receiving said at least one lower claw of said first plate when said recess receives said at least one upper claw of said first plate; at least one second electrical connection connected to said second plate for coupling with said at least one first electrical connection of said first plate when said recess receives said at least one upper claw and said slot receives said at least one lower claw; and locking means associated with said slot for locking said lower claw within said slot.
Claim 2
Dependent Claim
279 words
A connector unit for connecting two electrical devices together, the connector unit comprising: a first connector element and a second connector element, said first and second connector elements being complementary to one another; said first connector element being for attachment to one of the two electrical devices and said second connector element being for attachment to the other of the two electrical devices; said first connector element including: a first plate; at least one upper claw attached to said first plate; at least one lower claw attached to said first plate; and at least one first electrical connection connected to said first plate; said second connector element including: a second plate having an upper edge and a lower edge; at least one recess defined in said upper edge of said second plate for receiving said at least one upper claw of said first plate to form an elongated hinge means for allowing hinging movement between said first and second plate, said first plate being hangable from said second plate upon receipt of said at least one upper claw by said at least one recess; at least one slot defined in said second plate for receiving said at least one lower claw of said first plate when said recess receives said at least one upper claw of said first plate; at least one second electrical connection connected to said second plate for coupling with said at least one first electrical connection of said first plate when said recess receives said at least one upper claw and said slot receives said at least one lower claw; and locking means associated with said slot for locking said lower claw within said slot.
