Abstract

A cell connector bar or strap for connecting or coupling electric cells, both electrically and physically, is provided with a heat-sink for dissipating heat generated by the cells when charging rechargeable cells and during rapid discharge of the battery formed by the coupled cells. The heat-sink, in its preferred structure is a plurality of heat dissipating elements, such as extending fingers, extending from the body of the cell connector bar.

Claims

1. An apparatus for electrically coupling two electric cells for defining a battery where each electric cell of said two electric cells include a positive terminal and a negative terminal, said apparatus comprising:

a) a body having a first extreme and a second extreme, said first extreme for making contact with a terminal on a first electric cell and said second extreme for making contact with a terminal on a second electric cell for making an electric connection between said first electric cell and said second electric cell; and

b) a heat-sink coupled to said body, said heat-sink defined by one or more finger members extending from said body.

2. An apparatus for electrically coupling two electric cells for defining a battery where each electric cell of said two electric cells include a positive terminal and a negative terminal, said apparatus comprising:

a) a body having a first extreme and a second extreme, said first extreme for making contact with a terminal on a first electric cell and said second extreme for making contact with a terminal on a second electric cell for making an electric connection between said first electric cell and said second electric cell; and

b) a heat-sink coupled to said body, and said body has a length between said first extreme and said second extreme and a width extending along said length and said heat-sink includes a plurality of spaced fingers extending from said width of said body.

3. An apparatus for electrically coupling two electric cells for defining a battery where each electric cell of said two electric cells include a positive terminal and a negative terminal, said apparatus comprising:

a) a body having a first extreme and a second extreme, said first extreme for making contact with a terminal on a first electric cell and said second extreme for making contact with a terminal on a second electric cell for making an electric connection between said first electric cell and said second electric cell; and

b) a heat-sink coupled to said body, and said heat-sink is defined by a plurality of spaced fingers extending from said body and at least one finger of said spaced fingers is disposed angularly from said body with respect to a horizontal.

4. An apparatus for electrically coupling two electric cells for defining a battery where each electric cell of said two electric cells include a positive terminal and a negative terminal, said apparatus comprising:

a) a body having a first extreme and a second extreme, said first extreme for making contact with a terminal on a first electric cell and said second extreme for making contact with a terminal on a second electric cell for making an electric connection between said first electric cell and said second electric cell; and

b) a heat-sink coupled to said body, and said body has a length between said first extreme and said second extreme and a width extending along said body, said width defined by a first side edge and a second side edge and said heat-sink is defined by a plurality of spaced fingers extending from said first side edge.

5. An apparatus as in claim 4 and in which said heat-sink further includes a second plurality of spaced fingers.

6. An apparatus as in claim 5 wherein said second plurality of spaced fingers extend from said second side edge.

7. An improved cell connector bar for connecting terminals of at least two electric cells each cell of said two electric cells having a first terminal and a second terminal, said cell connector bar comprising:

a) a body having a length defines by a first extreme and a second extreme, said length having a width defined by a first side and a second side; and

b) a heat-sink defined by at least a member extending from said first side of said body and said at least a member extending from said first side of said body is defined by a plurality of spaced members extending from said first side.

8. An improved cell connector bar as in claim 7 and in which said heat-sink further includes at least a second member extending from said second side of said body.

9. An improved cell connector bar as in claim 8 and in which said at least a second member is defined by a plurality of spaced members extending from said second side of said body.

10. An improved electric cell connector bar for connecting at least two electric cells for defining a battery where each cell of said at least two electric cells include a first terminal and a second terminal and said improved electric cell connector bar connects two of said at least two electric cells both electrically and physically, said electric cell connector bar comprising:

a) a body having a length defined by a first extended foot and a second extended foot, said length having a width defined by a first edge and a second edge, said body fabricated from a material having an electric conductor characteristics and an heat conductor characteristics; and

b) a heat-sink defined by at least a member extending from said first edge, fabricated from said material.

11. An improved electric cell connector bar as in claim 10 and in which said heat-sink further includes at least a second member extending from said second edge of said body.

12.
