Definitions
- the present invention relates to a battery terminal connected to the electrode (battery post) of a battery installed in a motor vehicle, and particularly to a battery terminal installed by means of tightening a bolt in a clamping member from vertically above.
- annular post fitting is fit over the battery post protruding from the battery.
- the base members contiguous to the free ends of the post fitting are then clamped tight to the post via a bolt and nut tightened from the side using an impact wrench or other power tightening tool.
- the battery terminal shown in Figs. 5a and 5b has therefore been proposed (Utility Model Publication (examined) 4-9736) as a means of solving this problem.
- opposing base 3b and tightening members 3c forming a taper that is wider at the bottom than at the top are formed as part of the terminal body 3.
- Torque control is also not generally used when tightening the battery terminal bolts.
- the terminal bolt may be overtightened due to continued tightening after the post fitting is sufficiently clamped to the battery post.
- US-A-4 747 793 discloses a battery terminal in which the terminal body comprises a folded element having top and bottom ring shaped post fitting members defining the post fitting opening which is opened towards the folded end of the folded element, so that said arms are formed as folded arms, and wherein at least one of said ring-shaped post fitting members is formed with notches in the inside circumferential surface of said post fitting member.
- an object of the present invention is to provide a battery terminal according to the preamble of claim 1, which when tightened to the battery post by means of a bolt and using an impact wrench of which the torque is unregulated will not turn on the battery post even when additional torque is applied by the impact wrench after the battery terminal is tightened sufficiently to the battery post.
- a battery terminal for tightly clamping a battery annular post comprises: a fold element having top and bottom ring-shaped post fitting members, said ring-shaped post fitting members formed with an annular post fitting opening which is opened towards the folded end for defining two folded arms, said two folded arms having tapered walls; a clamping member having tapered sides; an urging means for urging said two folded arms into said clamping member for sliding said tapered walls along said tapered sides to close said two folded arms; and notches having pointed tips projecting from the inside circumference surface of at least one of said ring-shaped post fitting members for biting into the outside circumference surface of the battery post.
- the urging means is formed by a nut held in a space between said two folded arms and a bolt engaged to the clamping member and threaded to said nut for sliding said tapered walls along said tapered sides to close said two folded arms.
- the notches formed on the inside circumference surface of the post fitting may be formed as a series of teeth that are wave-shaped in cross section and continuous in the circumferential direction. Said notches may also be formed discontinuously spaced in the circumferential direction.
- the battery terminal 10 of the present invention comprises terminal body 11, clamping member 12, bolt 14, nut 15, and ring 16.
- the terminal body 11 is a stud bolt type terminal, and is manufactured by shaping and bending a single metal piece in two as shown in the figure.
- a stud bolt 18 is provided in the wire connector 17 at one end of the battery terminal.
- the terminal (not shown in the figures) crimped to an electrical wire is placed over and clamped to the stud bolt 18 using a nut (not shown in the figures).
- terminal body 11 may alternatively be a crimped-barrel terminal whereby a barrel integrally formed to the electrical wire connector is crimped to secure and connect the electrical wire to the terminal.
- the terminal body 11 forms the wire connector 17, post fitting 20, and clamping end 21 by bending top and bottom parts, which are basically identical in shape, around a bending member at one end such that the top part vertically opposes the bottom part.
- both top and bottom parts have at one end a rectangularly shaped wire connector 17A or 17B, each being connected to a ring-shaped post fitting 20A or 20B, respectively.
- a cylindrical member 20A-1 or 20B-1 stands around the inside circumference edge of the post fittings 20A, 20B.
- Notches 20A-2, 20B-2 having a wave-shaped cross section are formed continuously around the inside circumference surfaces of the cylindrical members 20A-1, 20B-1.
- the tips 20A-3, 20B-3 of the projecting ends of each of the notches 20A-2, 20B-2 project in an acute point to the inside of the post fittings 20A and 20B.
- the end opposite the electrical wire connector side of the post fittings 20A, 20B is open as shown in Fig. 1.
- Clamping ends 21A, 21A', 21B, and 21B' are provided contiguous to each free end.
- the right side clamping ends 21A and 21B and the left side clamping ends 21A' and 21B' are respectively linked by bending members 21C and 21C', respectively.
- the right and left clamping ends 21A, 21B and 21A', 21B' are separated by a space S.
- Slide members 21A-1 and 21A'-1 sloping down to the outside are provided at the outside edges of the top clamping ends 21A, 21A'.
- Slide members 21B-1 and (21B'-1 not shown in the figures) sloping up to the inside are provided at the outside edges of the bottom clamping ends 21B, 21B'.
- the clamping member 12 is a C-shaped member comprising a top 12a and two sides 12b and 12c.
- a bolt hole 24 is provided at the center of the top 12a.
- side walls 26, 27 that are open to the bottom are provided in the middle of the sides 12b, 12c, which extend perpendicularly from the edges of the top 12a.
- Taper faces 26a, 26b, 26a', 26b', 27a, 27b, 27a', and 27b' forming tapered members widening to the bottom are provided in horizontal opposition in two vertical stages on the right and left side edges of the side walls 26, 27.
- the horizontal faces connecting the taper faces 26a ?? 27b' are the shoulders 26c, 26c', 27c, and 27c'.
- the clamping member 12 is assembled to the battery terminal with the taper faces 26a ?? 27b' contacting and sliding freely along the slide members 21A-1 ?? 21B'-1 of the clamping end 21.
- a nut 15 is housed in the space S in the clamping end 21, and the bolt 14 is threaded partially into the nut 15 through the bolt hole 24 of the clamping member 12.
- a ring 16 (not shown in Figs. 3a and 3b, but only shown in Fig. 1) is fit to the top of the shank 14b of the bolt 14. This ring 16 causes the clamping member 12 to rise as the bolt 14 is loosened.
- the battery terminal 10 is mounted to the battery post 2 by fitting the post fittings 20A, 20B over the post.
- the post fittings 20A, 20B can be easily fit over the battery post because the free ends of the fittings are open wide.
- the head 14a of the bolt 14 is then turned and tightened into the nut 15 using a power tightening tool such as an impact wrench R (Fig. 2a) or manually using an open-end wrench R' (Fig. 2b) or other wrench.
- a power tightening tool such as an impact wrench R (Fig. 2a) or manually using an open-end wrench R' (Fig. 2b) or other wrench.
- the inside diameter of the center opening becomes smaller, and the inside circumference surfaces of the post fittings 20A, 20B approach the outside circumference surface of the post 2.
- a reliable electrical connection between the battery terminal and battery post can also be assured with a battery terminal according to the present invention because the battery terminal is clamped to the battery post with the tips of the notches of the post fitting biting into the outside circumference surface of the battery post.
- the productivity of the battery terminal installation task can thus be improved because special attention is not required to prevent overtightening of the bolt or contact problems caused by insufficient bolt tightening.
- the battery terminal of the invention also helps prevent damage to components resulting from inexperience tightening the battery terminal.
