DETAILED DESCRIPTION

(8) Referring now to FIGS. 1 and 2, the invention is a battery terminal clamp 10 for a rechargeable storage battery. The battery terminal clamp 10 is used, for example, to connect a rechargeable storage battery (not shown) of an automobile or other motor vehicle to the accessories, safety and engine control systems, and other power-consuming parts and components of that vehicle. Rechargeable storage batteries used in most contemporary gasoline and hybrid vehicles are rated at approximately twelve volts.

(9) The battery terminal clamp 10 of the invention is made from a rugged, electrically conductive metal, such as a copper material, or a brass material, or any other suitable conductive metal or alloy. In this case, the preferred alloy is a C194 alloy, which is a copper alloy, and specifically a copper-iron-phosphorus alloy.

(10) The battery terminal includes a main body portion 12. In this embodiment, the battery terminal clamp 10 and its body portion 12 are made from a one-piece, stamped element. In the preferred embodiment of the invention, the stamped element is made from C194 alloy having a thickness of approximately 1.63 millimeters. The stamped element is folded and further stamped in the manner necessary to create the battery terminal clamp 10 having the shape depicted in FIGS. 1-6. Preferably, the battery terminal clamp 10 and its body portion 12 are plated with tin, at a plating thickness of at least 0.001 millimeters. As shown in FIGS. 4-5, the main body portion 12 has a width W.sub.B and a length L.sub.B, wherein the length L.sub.B is greater than the width W.sub.B.

(11) The body portion 12 may include a top planar element 14, and may further include a bottom planar element 16. When battery terminal clamp 10 is mechanically secured to a top-mounted terminal post of a rechargeable storage battery, the top planar element 14 faces upward, and is normally visible to the motorist or mechanic. In contrast, the bottom planar element 16 faces downward, and abuts against and is supported by the outer battery case of the rechargeable storage battery. As shown in FIGS. 1-6, the top planar element 14 is coupled to the bottom planar element 16 with an elongated bolt 15 extending laterally between the top and bottom planar elements 14, 16.

(12) Each of the top 14 and bottom planar elements 16 include an orifice 18 for accommodating the terminal post of the rechargeable storage battery. The portion of this orifice 18 within the top planar element 14 has a diameter of approximately 18.08 millimeters, while the portion of this orifice 18 within the bottom planar element 16 has a diameter of approximately 18.66 millimeters. The top and bottom orifices 18 are positioned between the elongated bolt 15 and the tab 20.

(13) Referring now to FIGS. 1-3 and especially FIG. 5, the top planar element 14 includes a first flange or top flange 30 that extends downwardly from the bottom surface 32 of the top planar element 14. The orifice 18 in the top planar element 14 is defined by the top flange 30. The bottom planar element 16 includes a second flange or bottom flange 34 that extends upwardly from the top surface 36 of the bottom planar element 16. The orifice 18 in the bottom element 16 is defined by bottom flange 34. There is a gap 38 between the bottom 40 of the first flange 30 and the top 42 of the second flange 34. In this way, the flanges 30 and 34 are separated by this gap 38. Referring to FIG. 5, a first space or top flange space 44 is disposed along an extent of the first flange 30 and a second space or bottom flange space 46 is disposed along an extent of the second flange 34. The first and second spaces 44, 46 are offset from one another as shown in FIG. 5 and form a semi-continuous configurations of the top flange 30 and bottom flange 34.

(14) As may be seen in each of FIGS. 1-6, a tab 20 is integrally formed with the body portion 12. In this context, integrally formed means that the tab 20 is made of the same stamping as the body portion 12, i.e., that the tab 20 and its body portion 12 are of one piece of metal. Because the tab 20 is integrally formed with the body portion 12, the thickness of the tab 20 is substantially identical to the thickness of the body portion 12, i.e., approximately 1.63 millimeters. As shown in FIGS. 4-5, the tab 20 portion 12 has a width W.sub.T and a length L.sub.T, wherein the length L.sub.T is greater than the width W.sub.T.

(15) In this preferred embodiment, as may best be seen in FIGS. 1-5, the tab 20 is of a substantially rectangular shape. The tab 20 also extends upwardly from the top planar element 12. This specific orientation of tab 20 has certain advantages. As may be seen in FIG. 6, no portion of the tab 20 extends beyond the entire perimeter of the body portion 12. More specifically, as may also been seen in FIG. 6, no portion of the tab 20 extends outwardly beyond the right side wall 22 and the left side wall 24 of the body portion 12.

(16) Because of these features and the orientation of the tab 20, the motorist or mechanic who seeks to jump start a battery will have easy access to the tab 20. First, the tab 20 is at the top of the battery terminal clamp 10, which is an area that is generally open to view, unobstructed, and easily accessible.

(17) Second, the tab 20 is not outside of the perimeter of the body portion 12 of the battery terminal clamp 10, and specifically the tab 20 is inboard both the right side wall 22 and the left side wall 24 of the body portion 12. As a result, the tab 20 is not in an area closely adjacent to other under-hood components, nor near walls or suspension components that could obstruct access to that tab 20.

(18) As may best be seen in FIGS. 3 and 4, the tab 20 is positioned at an angle to the top planar element 14. The angle between the tab 20 and the top planar element 14 should be adequate to ensure that the jaws of a jumper cable will be able to be securely fastened to the tab 20, and especially to the underside 26 of the tab 20. The probable range of angles that the tab 20 may extend upwardly is from about an acute angle of 30 degrees to about an obtuse angle of 120 degrees. The most preferred angle that this tab 20 may extend upwardly from the top planar element is forty-five (45) degrees.

(19) For these and other reasons, the tab 20 is especially suited for facilitating the attachment of the jaws of jumper cables to the body portion 12. In this way, the tab 20 enables the easy, quick jumping of a discharged, rechargeable storage battery. This flat, generally rectangular construction provides an adequate, effective mechanical and electrical connection between the jaws of the jumper cables and the tab 20.

(20) As may best be seen in FIGS. 1-4, the battery terminal clamp 10 of the invention may further include: (i) a base portion 27 adjacent the top planar element 14, (ii) an angled portion 28 at the distal end of the tab 20, and (iii) an intermediate portion 29 positioned between the base portion 27 and the angled portion 28. This angled portion 28 provides additional aid in securing the jumper cables to the tab 20 during the jumping operation, and particularly in aiding in preventing the inadvertent removal of the jumper cables from the tab 20 during that jumping operation.

(21) As may best be understood from the two horizontal, dashed lines of FIG. 6, in a preferred embodiment of the invention the lengthwise axis of the tab 20 is generally parallel with the lengthwise axis of the body portion 12. This common axial orientation of the tab 20 and the body portion 12 is yet another reason why the tab 20 does not extend laterally outwardly from the perimeter of the battery terminal clamp 10.
