[Figure 2] 1 is a perspective view showing a state in which the battery terminal according to the embodiment is assembled to a battery post and a terminal. FIG. [Figure 3] FIG. 2 is a perspective view of a battery terminal according to the embodiment. DETAILED DESCRIPTION OF THE INVENTION

[0010] The battery terminal according to the present embodiment will be described in detail below with reference to the drawings. Note that the dimensional proportions in the drawings are exaggerated for the sake of convenience and may differ from the actual proportions.

[0011] As shown in FIG. 1, the battery terminal 1 according to this embodiment is electrically connected to, for example, a battery (not shown) mounted on a vehicle and an electrical component (not shown) mounted on the vehicle, and electrically connects the battery and the electrical component.

[0012] As shown in FIGS. 1 and 2, the battery is formed, for example, in a rectangular parallelepiped shape. A battery post 101 protruding upward is provided on the upper surface of the battery. The battery post 101 is formed in a cylindrical shape so that its diameter decreases upward from the battery side. A battery terminal 1 is electrically connected to the battery post 101, and the battery and the battery terminal 1 are electrically connected.

[0013] As shown in Figures 1 and 2, an electric wire 103 is electrically connected to the electrical component. A terminal 105 is electrically connected to an end portion of the electric wire 103. The terminal 105 has an electric wire connecting portion 107 and an electrical connection portion 109. The electric wire connecting portion 107 has a crimping piece that is crimped to the insulating coating of the electric wire 103, and a crimping piece that is crimped to the conductor of the electric wire 103. The crimping piece fixes the terminal 105 to the end portion of the electric wire 103 by being crimped to the insulating coating of the electric wire 103. The crimping piece electrically connects the terminal 105 and the electric wire 103 by being crimped to the conductor of the electric wire 103. The electrical connection portion 109 is formed from a single member that is continuous with the electric wire connecting portion 107 and is formed in a flat plate shape. The electrical connection portion 109 is bent at a joint with the electrical wire connection portion 107 so that the electrical wire 103 can be arranged along the side surface of the battery. A terminal insertion hole 111 is formed in the electrical connection portion 109 so as to penetrate the electrical connection portion 109. A battery terminal 1 is electrically connected to the electrical connection portion 109, and the electrical component and the battery terminal 1 are electrically connected to each other.

[0014] As shown in FIGS. 1 to 3, the battery terminal 1 includes a main body 3, a battery connection portion 5, and a terminal connection portion .

[0015] The main body 3 has a pair of plate-like members 9A and 9B formed in the shape of rectangular flat plates. The pair of plate-like members 9A and 9B are made of a conductive material such as metal. When the battery terminal 1 is placed on the battery, one plate-like member 9A is positioned on the battery side. When the battery terminal 1 is placed on the battery, the other plate-like member 9B is positioned above the first plate-like member 9A and spaced apart from the first plate-like member 9A. The pair of plate-like members 9A and 9B are connected via a connecting portion 11 formed of a single continuous member on one side in the longitudinal direction. In a free state, the connecting portion 11 positions the second plate-like member 9B at an upward inclination relative to the first plate-like member 9A. The connecting portion 11 allows the other side of the second plate-like member 9B to elastically deform in a direction approaching the first plate-like member 9A.

[0016] The battery connection part 5 is provided on one longitudinal side (the coupling part 11 side) of the main body 3 so as to be positioned at the battery post 101 when the battery terminal 1 is placed on the battery. The battery connection part 5 has post insertion holes 13A, 13B formed by penetrating the pair of plate-like members 9A, 9B, respectively. When the battery terminal 1 is placed on the battery, the battery post 101 is inserted and placed in the post insertion holes 13A, 13B.

[0017] The inner diameter of the post insertion hole 13A is set to be equal to or slightly smaller than the outer diameter of the base side of the battery post 101, which is the largest diameter. Therefore, when the battery post 101 is inserted, the inner surface of the post insertion hole 13A comes into tight contact with the outer surface of the battery post 101, electrically connecting the battery and the battery terminal 1. At this time, the post insertion hole 13A is press-fitted into the outer surface of the battery post 101, and the battery terminal 1 is fixed to the battery post 101.

[0018] The inner diameter of the post insertion hole 13B is smaller than the inner diameter of the post insertion hole 13A and is set to be equal to or slightly smaller than the outer diameter between the middle and base ends of the battery post 101. When the plate-shaped member 9B is in a free state and the battery post 101 is inserted through it, the post insertion hole 13B is positioned above the middle end of the battery post 101. When the plate-shaped member 9B elastically deforms, the post insertion hole 13B is positioned between the middle and base ends of the battery post 101. Therefore, when the plate-shaped member 9B elastically deforms with the battery post 101 inserted through it, the inner surface of the post insertion hole 13B comes into tight contact with the outer surface of the battery post 101, electrically connecting the battery and the battery terminal 1. At this time, the post insertion hole 13B is press-fit into the outer surface of the battery post 101, and the battery terminal 1 is fixed to the battery post 101.

[0019] The terminal connection portion 7 is provided on the other side in the length direction of the main body portion 3 (opposite to the connecting portion 11). The terminal connection portion 7 has a bolt 15, a bolt insertion hole 17, and a nut 19.

[0020] Bolt 15 is disposed on one plate-like member 9A. The head of bolt 15 is fixed to fixing portion 21 formed by folding back an end of one plate-like member 9A, and the threaded portion is exposed from through-hole 23 of fixing portion 21. The threaded portion of bolt 15 protrudes toward the other plate-like member 9B.

[0021] The bolt insertion hole 17 is formed in the other plate-like member 9B so as to penetrate the plate-like member 9B. The threaded portion of the bolt 15 is inserted into the bolt insertion hole 17. The inner diameter of the bolt insertion hole 17 is set so as not to interfere with the threaded portion of the bolt 15 when the plate-like member 9B is elastically deformed.

[0022] The nut 19 is fastened to the threaded portion of the bolt 15 with the terminal insertion hole 111 of the electrical connection portion 109 of the terminal 105 inserted into the threaded portion of the bolt 15. A washer 25 that comes into contact with the electrical connection portion 109 of the terminal 105 is integrally provided with the nut 19. When the nut 19 is fastened to the threaded portion of the bolt 15, the electrical connection portion 109 of the terminal 105 is sandwiched between the nut 19 and the other plate-like member 9B and brought into contact with the plate-like member 9B, electrically connecting the terminal 105 and the battery terminal 1. At this time, the electrical connection portion 109 is in pressure contact between the nut 19 and the other plate-like member 9B, and the terminal 105 is fixed to the battery terminal 1.

[0023] When the nut 19 is fastened to the bolt 15, it presses the other plate-shaped member 9B toward the one plate-shaped member 9A, elastically deforming it and changing its position. At this time, the other plate-shaped member 9B is biased toward the nut 19 by the biasing force of the elastically deformable connecting portion 11. Therefore, the thrust generated by fastening the nut 19 to the bolt 15 can be stably transmitted to the other plate-shaped member 9B. The post insertion hole 13B formed in the other plate-shaped member 9B, whose position has been changed, changes its position relative to the battery post 101 (here, moves toward the base). As a result, the post insertion hole 13B is in close contact with the battery post 101, allowing the battery terminal 1 to be electrically connected to the battery post 101. Therefore, the battery terminal 1 can be electrically connected to the battery post 101 and the terminal 105 with a single fastening operation, improving assembly ease. Furthermore, since there is no need to provide a fastening structure around the battery connection part 5, it is possible to reduce the installation space around the battery connection part 5. In addition, it is possible to reduce the number of components of the battery connection part 5, thereby reducing the weight and cost.

[0024] As an example of assembling such a battery terminal 1, first, the post insertion holes 13A, 13B of the battery connection portion 5 are inserted into the battery post 101, and the battery terminal 1 is placed on the battery. Next, the bolt 15 of the terminal connection portion 7 is inserted into the terminal insertion hole 111 of the electrical connection portion 109 of the terminal 105, and the terminal 105 is placed on the battery terminal 1. Then, the nut 19 is fastened to the bolt 15 of the terminal connection portion 7, and the battery terminal 1 is electrically connected to the battery post 101 and the terminal 105, completing the assembly.

[0025] The battery terminal 1 includes a main body 3 having a pair of plate-shaped members 9A and 9B. The main body 3 also includes a battery connection portion 5 electrically connected to a battery post 101, and a terminal connection portion 7 electrically connected to a terminal 105. The battery connection portion 5 has post insertion holes 13A and 13B formed in the pair of plate-shaped members 9A and 9B, respectively, through which the battery post 101 is inserted. The terminal connection portion 7 has a bolt 15 fixed to one plate-shaped member 9A and a bolt insertion hole 17 formed in the other plate-shaped member 9B through which the bolt 15 is inserted. The terminal connection portion 7 also has a nut 19 that, when fastened to the bolt 15, brings the terminal 105 into contact with the other plate-shaped member 9B. The post insertion hole 13B of the other plate-shaped member 9B comes into contact with the battery post 101 when the nut 19 is fastened to the bolt 15, thereby changing the position of the other plate-shaped member 9B.

[0026] When the nut 19 is fastened to the bolt 15, it brings the terminal 105 into contact with the other plate-like member 9B, electrically connecting the terminal 105 to the battery terminal 1. At this time, the position of the other plate-like member 9B is changed, and the post insertion hole 13B comes into contact with the battery post 101, electrically connecting the battery post 101 to the battery terminal 1. Therefore, the battery terminal 1 can be electrically connected to the battery post 101 and the terminal 105 with a single fastening operation, improving ease of assembly.

[0027] Therefore, such a battery terminal 1 can improve the ease of assembly.

[0028] The pair of plate-like members 9A, 9B are connected at their ends opposite the terminal connection portion 7 via a connecting portion 11 that is elastically deformable.

[0029] The other plate-like member 9B is biased toward the nut 19 by the biasing force of the elastically deformable connecting portion 11. Therefore, the thrust force generated by fastening the nut 19 to the bolt 15 can be stably transmitted to the other plate-like member 9B, and fluctuations in the position of the other plate-like member 9B caused by fastening the nut 19 can be stabilized.

[0030] Moreover, the post insertion hole 13B of the other plate-like member 9B is set to have a smaller diameter than the post insertion hole 13A of the one plate-like member 9A.

[0031] Therefore, when the position of the other plate-shaped member 9B is changed, the adhesion between the post insertion hole 13B and the battery post 101 can be improved, and the reliability of the electrical connection between the battery post 101 and the battery terminal 1 can be maintained.

[0032] Although the present embodiment has been described above, the present embodiment is not limited to this, and various modifications are possible within the scope of the gist of the present embodiment.

[0033] For example, the bolt of the terminal connection portion is fixed to a fixing portion formed by folding back a plate-shaped member, but this is not limited to this, and the bolt may be fixed to the plate-shaped member by a joining means such as welding.

[0034] Furthermore, the pair of plate-like members are connected via an elastically deformable connecting portion, but this is not limited to this. For example, the pair of plate-like members may be connected via an engaging portion that allows the position of the other plate-like member to be changed. [Explanation of symbols]
