[0034] The first battery clamping member 12 has an arcuate inner edge 18 located on either side of the first battery clamping member 12. The second battery clamping member 22 has an arcuate inner edge 26 located on either side of the second battery clamping member 22. See Figures 4 and 5.

[0035] The inner battery clamping apparatus 10B includes a first inner battery clamping portion 112 made of a conductive metal (e.g., stamped or forged from sheet metal) having an inner handle portion 114 and an inner clamping portion 116. The first inner battery clamping member 112 is pivotally connected together (e.g., via pivot pin 130, see FIG. 9) to a second inner battery clamping portion 120 having an inner handle portion 122 and an inner clamping portion 124, as shown in FIG.

[0036] The first inner battery clamping member 112 is provided with a slot 116C (FIG. 9) for mechanically connecting (e.g., snap-fit ​​connection) with a protrusion (e.g., snap-fit ​​protrusion 16D, which is the same as snap-fit ​​protrusion 24D shown in FIG. 1) of the first outer battery clamping member 12. The second inner battery clamping member 120 is provided with a slot 124C (FIG. 9) for mechanically connecting (e.g., snap-fit ​​connection) with a protrusion (e.g., snap-fit ​​protrusion 24D shown in FIG. 1) of the second outer battery clamping member 20.

[0037] The snap fit connections described above are located on the outer clamp portions 16, 24. Additional connections (e.g., mechanical connections, additional snap fit connections, etc.) may be provided on the outer handle portions 14, 22. For example, the outer handle portions 14, 22 may include transverse cross members 14F, 14G, 22F, 22G (FIG. 7) configured to connect to (e.g., capture) the inner handle portions 114, 122. Specifically, the transverse cross members 14F, 22F wrap across and capture the inner sides (e.g., inner edges) of the inner handle portions 114, 122. The transverse cross members 14G, 22G wrap across and capture the edges and ends of the inner handle portions 114, 122. During assembly, each inner handle portion 114, 122 is slid under a lateral cross member 14F, 14G, 22F, 22G until the inner handle portion 114, 122 bottoms out within the cross member 22F, 22G, and then the outer clamp portion 16, 24 is snap-fitted onto the inner clamp portion 116, 124.

[0038] Again, the inner battery clamp 10B is made of a conductive material such as metal. For example, the first inner battery clamping portion 112 and the second inner battery clamping portion 120 may be made of stamped sheet metal (e.g., steel, aluminum, copper, brass, a metal alloy, or other suitable conductive material) and then metal plated (e.g., with chrome, nickel, a metal alloy) for corrosion resistance. The first inner battery clamping portion 112 and the second inner battery clamping portion 120 are then assembled together (FIG. 9) using a spring 131 (FIGS. 17, 18) and a pivot pin 130.

[0039] The inner battery clamp 10B is configured to be connectable with a battery cable 154 (FIG. 16). For example, the inner handle portion 122 (FIG. 12) is fitted with a battery end connector 128 as shown in FIGS. 12, 15, 17, and 18. The battery cable connector 128 has, for example, a first segmented cylindrical metal plate end oriented parallel to the longitudinal axis of the inner handle portion 122. The first segmented cylindrical metal plate end is in an open position (FIG. 17) prepared to receive a battery cable end 142A. Specifically, the battery cable 142 includes a battery cable end 142A with insulation 142B removed to expose it. The exposed battery cable end 142 is inserted into the receiver 128A of the battery cable connector 128, and then the battery cable connector 128 is pushed inward by a force F (FIG. 17) or crimped closed to fix and anchor the exposed battery cable end 142 within the receiver 128A of the battery cable connector 128. Alternatively, the first segmented cylindrical metal sheet end may be a first continuous cylindrical metal sheet end. For example, the first continuous cylindrical metal sheet end may include one or more threaded through holes along its side, each of which accommodates a set screw for fixing and anchoring the battery cable end 142A within the receiver 128A of the battery cable connector 128. Additionally, the battery cable end 142A (FIGS. 17 and 18) may be soldered and / or welded to the battery cable connector 128.

[0040] 17, the end of the battery cable connector 128 may be provided with interlacing fingers 128B, 128C. The interlacing fingers 128B may be forced inwardly of the exposed battery cable end 142A to further grip the strands of the exposed battery cable end 142A. Additionally, the exposed battery cable end 142A may be soldered and / or welded to further secure and anchor the battery cable end 142A within the receiver 128A of the battery cable connector 128.

[0041] The battery cable connector 128 includes a first segmented cylindrical sheet metal end having initially spaced edges with interlaced fingers 128B, 128C, and a second segmented cylindrical portion 122F having initially spaced edges 122FA, 122FB, as shown in Figure 17. After the battery cable end 142A of the battery cable 142 is fully inserted into the battery cable connector 128, the battery cable connector 128 is pressed and / or crimped together, forcing the spaced edges with the interlaced fingers 128B, 128C together and forcing the spaced edges 122FA, 122FB together.

[0042] The battery cable connector 128 further comprises a third funnel-shaped metal plate section having an outwardly tapered wall 122E and a fourth section having a pair of spaced apart metal plates 140A, 140A. The metal plates 140A, 140A of the fourth section (FIGS. 15 and 18) may be pressed together to provide additional gripping force to the battery cable end 142B. Additionally, the walls 140A, 140A may be soldered and / or welded to the battery cable end 142A for increased electrical conductivity, further securing and anchoring the battery cable end 142A to the battery cable end connector 128.

[0043] As shown in Fig. 18, the thickness of the first divided cylindrical metal plate end 128 is greater than the thickness of the second divided cylindrical metal plate portion 122F. Furthermore, the inner diameter of the first divided cylindrical end 128 is the same as the inner diameter of the second divided cylindrical metal plate portion 122F. The greater thickness of the first divided cylindrical metal plate portion 128 improves the gripping force of the battery cable end portion after it is pushed inward or crimped closed.

[0044] The spring 131 (FIG. 19) is installed in the inner battery clamp 10B and biases the outer clamp portions 12, 16. Specifically, the spring 131 is provided with a through hole 131B that accommodates the pivot pin 130, and at the same time, an arm 131C having an end 131D contacts the inner surfaces of the arm portions 114, 122 (FIG. 9) of the inner battery clamp 10B.
