  In the above configuration and structure, the battery terminal 101 is attached to the battery post 102 by tightening the bolts 121 inserted from the side to the connecting plate portions 107, 107 of the annular portions 103, 104 with the nuts 122, thereby setting the tightening gaps 110, 110. It is designed to be completed by narrowing. When tightening, the post insertion holes 108 and 108 are reduced in diameter so that the contact portions 109 and 109 come into contact with the battery post 102.

  Incidentally, the connecting plate portions 107 and 107 have a shape that is bent in a substantially U shape as described above, and there is a restriction that a predetermined clearance must be secured with respect to the shaft portion of the bolt 121 inserted from the side. That is, the bending shapes of the connecting plate portions 107 and 107 are determined according to the size of the bolt 121.

  The specific shapes of the connecting plate portions 107 and 107, the annular portion 103 and the joining plate 105 as the upper plate portion, and the annular portion 104 and the joining plate 106 as the lower plate portion are disclosed in, for example, Patent Document 2 below. It is disclosed.

  In FIG. 9, the battery terminal main body 51 in the battery terminal according to the third embodiment is reinforced with respect to the battery terminal main body 4 (see FIGS. 1 to 4) in the battery terminal 1 according to the first embodiment. (The other parts are the same as those in the first embodiment). The difference will be specifically described below.

  A pair of free end portions 12, 12 are formed on the annular portion 11 of the upper plate portion 8. A pair of tightening action portions 19, 19 are formed on the pair of free end portions 12, 12. And the reinforcement part 52 is formed in the front end of a pair of clamping action parts 19 and 19 by bending. The reinforcement part 52 is formed as a part which raises the intensity | strength of an up-down direction.

  The reinforcing portion 52 can be applied to the tightening operation portion 43 and the tightening operation portion 45 of the second embodiment.

  Embodiment 4 will be described below with reference to the drawings. 10A and 10B are views showing a battery terminal main body as still another example, in which FIG. 10A is a perspective view seen from the post portion side, and FIG. 10B is a perspective view seen from the stud portion side. 11 is a view showing the battery terminal main body of FIG. 10, wherein (a) is a plan view, (b) is a left side view, and (c) is a right side view. In addition, the same code | symbol is attached | subjected to the same component as the said Examples 1-3, and detailed description is abbreviate | omitted.

  10 and 11, the battery terminal body 61 in the battery terminal of the fourth embodiment has a structure on the stud portion side with respect to the battery terminal body 4 (see FIGS. 1 to 4) in the battery terminal 1 of the first embodiment. There are some differences. Moreover, it is different also in the point from which a stud bolt differs (other parts are the same as Example 1). The difference will be specifically described below.

  The battery terminal includes a battery terminal main body 61, a fastening bolt 5 and a nut 6 (see FIGS. 1 and 2) that are configured on the post portion 2 side of the battery terminal main body 61, and a stud portion 3 side of the battery terminal main body 61. A stud bolt 62 is provided.

  Since the battery terminal has the same configuration and structure on the post portion 2 side as in the first embodiment, detailed description thereof will be omitted here.

  The battery terminal body 61 is formed in the shape shown in the figure by pressing a conductive metal plate. In this embodiment, Sn plating is applied. The battery terminal main body 61 has an upper plate portion 63, a lower plate portion 64, and a connecting plate portion 65, which are formed by pressing the conductive metal plate.

  The upper plate portion 63 has an annular portion 11 and a pair of free end portions 12 and 12 on the post portion 2 side. Further, the upper plate portion 63 has a terminal block portion 66 and a coupling portion 67 on the stud portion 3 side.

  The terminal block portion 66 is a portion having a contact surface with the connection terminal 114, and is disposed and formed so as to be continuous with the rear end of the annular portion 11 through the coupling portion 67. The terminal block part 66 and the coupling part 67 are arranged on the same plane as the annular part 11.

  Similarly to the upper plate part 64, the lower plate part 64 has an annular part 24 and a pair of free end parts 25, 25 on the post part 2 side. Further, the lower plate part 64 has a terminal block part 68 and a coupling part 69 on the stud part 3 side.

  The terminal block 68 is arranged and formed so as to be continuous with the rear end of the annular portion 24 through the coupling portion 69. The terminal block 68 and the coupling part 69 are arranged on the same plane as the annular part 24. The terminal block 68 sandwiches and holds the head 70 of the stud bolt 62 with the terminal block 66 on the upper plate 63 side (in this embodiment, it is fixed by welding).

  The connecting plate portion 67 is formed in a flat plate shape in a substantially perpendicular direction with respect to the terminal block portions 66 and 68. Since the connecting plate portion 67 does not protrude rearward, the connecting plate portion 67 is formed so as to avoid interference with components that are connected and fixed to the stat portion 3. Further, the connecting plate portion 67 is also formed so as to eliminate dimensional restrictions with the above components.

  In addition, the present invention can of course be modified in various ways within the scope not changing the gist of the present invention.

  As described above with reference to FIGS. 1 to 11, the battery terminals 1 and 41 and the battery terminal bodies 51 and 61 have a design freedom in the structure on the post portion 2 side as compared with the battery terminal 101 of the conventional example. There is an effect that the strength can be imparted and the structure on the post part 2 side can be imparted with strength.
