It is arranged extending to the side. Here, the annular portion width direction is a direction intersecting with the axial direction along the center axis X of the battery post 51, here, a direction orthogonal to the axial direction and formed in the annular portions 21a and 21b, It is a direction which crosses 21i. The annular portion width direction typically corresponds to a direction along the direction (tightening direction) in which the annular portions 21a and 21b are tightened when the annular portions 21a and 21b are fastened to the battery post 51. The annular portion width direction of the present embodiment is a direction along the long side direction in a state where the battery terminal 1 is attached to the battery post 51.

  Specifically, the L-shaped bolt 24 includes a shaft portion 24a, a contact portion 24b, and a screwing portion 24c, which are integrally formed. The shaft portion 24a is formed in a cylindrical bar shape, and penetrates from the one end side of the annular portions 21a, 21b to the other end side of the annular portions 21a, 21b across the slits 21h, 21i along the annular portion width direction. The contact portion 24b is provided on one end side in the annular portion width direction of the shaft portion 24a. Here, the contact portion 24b is formed such that the shaft portion 24a penetrates from one end side of the annular portions 21a, 21b to the other end side of the annular portions 21a, 21b across the slits 21h, 21i along the annular portion width direction. In the state assembled to the main body portion 21, it is formed integrally with the shaft portion 24a at the end portion located on the notch portions 21m, 21n side. The contact portion 24b is a portion that contacts the annular portions 21a and 21b on one end side of the annular portions 21a and 21b with respect to the annular portion width direction. Here, the contact portion 24b is formed in a substantially rectangular plate shape, and the end portion on one side in the long side direction of the above-described tightening end portions 21k and 21l in a state where the L-shaped bolt 24 is assembled to the main body portion 21. It fits in each notch part 21m and 21n formed in this, and contact | abuts to the annular parts 21a and 21b. The screw portion 24c is provided on the other end side in the annular portion width direction of the shaft portion 24a. Here, the threaded portion 24c is such that the shaft portion 24a penetrates from one end side of the annular portions 21a, 21b to the other end side of the annular portions 21a, 21b across the slits 21h, 21i along the annular portion width direction. In the state assembled to the main body portion 21, it is formed integrally with the shaft portion 24a at the end opposite to the notches 21m and 21n. The threaded portion 24c is formed by bending the end portion on the other end side in the annular portion width direction of the shaft portion 24a into a substantially L shape along the axial direction. The screwing portion 24c is formed with a screwing groove 24d into which a fastening nut 25 described later can be screwed.

After that, the screwing portion 24c is erected along the axial direction to be assembled to the main body portion 21. That is, the L-shaped bolt 24 is assembled to the main body portion 21 in such a positional relationship as to cross the slits 211h and 21i along the annular portion width direction. When the L-shaped bolt 24 is assembled to the main body 21, the contact portion 24b fits into the notches 21m and 21n, and the screwing portion 24c sandwiches the tightening end portions 21k and 21l. It is located on the opposite side to 24b, and the contact part 24b and the screwing part 24c are opposed to the annular part width direction (long side direction). In the state where the L-shaped bolt 24 is assembled to the main body 21, the tip end of the screwing portion 24 c faces one side in the axial direction, here, the side opposite to the post standing surface 53, that is, the upper side in the vertical direction.

  The fastening nut 25 is screwed with the screwing portion 24 c of the L-shaped bolt 24. The fastening nut 25 moves along the axial direction by the screwing action with the screwing portion 24c as the shaft rotates around the axial direction.

  The bracket 26 is provided so as to be movable along the axial direction along with the movement along the fastening nut 25 and generates a pressing force in the annular portion width direction. Here, the bracket 26 moves along the axial direction along with the movement along the fastening nut 25 in a state where it is assembled to the screwing portion 24c, so that the other end side of the annular portions 21a and 21b, that is, screwing. On the side where the portion 24c is located, it comes into contact with the tightening end portions 21k, 21l of the annular portions 21a, 21b, and generates a pressing force in the annular portion width direction. The bracket 26 converts the axial tightening force generated between the fastening nut 25 and the L-shaped bolt 24 as the fastening nut 25 rotates in the axial direction into a pressing force in the annular portion width direction. Here, the pressing force in the annular portion width direction refers to the annular force in the direction of reducing the interval between the slits 21h and 21i of the annular portions 21a and 21b along the annular portion width direction between the bracket 26 and the contact portion 24b. It is the force which presses the parts 21a and 21b.

  Specifically, the bracket 26 is formed integrally with the base portion 26a formed in a substantially rectangular plate shape, and extends from the two opposite sides of the base portion 26a downward in the vertical direction. It is comprised including a pair of upright part 26b. The pair of upright portions 26b oppose each other in the short side direction. The bracket 26 is formed in a substantially U shape as a whole of the base portion 26a and the upright portions 26b by, for example, press bending of a metal plate. And the bracket 26 has the penetration part 26c formed in the base part 26a, and the taper surface 26d formed in each upright part 26b.

  The through portion 26c is a substantially circular through hole through which the screwing portion 24c passes, and is formed so as to penetrate the base portion 26a in the axial direction. The bracket 26 is assembled to the threaded portion 24c so as to be movable along the axial direction by inserting the threaded portion 24c along the axial direction into the penetrating portion 26c. In the bracket 26, each upright portion 26 b is positioned closer to the shaft portion 24 a than the base portion 26 a in a state where the bracket 26 is assembled to the screw portion 24 c in such a positional relationship that the screw portion 24 c is inserted into the through portion 26 c. Typically, in a state where the bracket 26 is assembled to the screwing portion 24c, the base portion 26a is located on the upper side in the vertical direction, and the upright portions 26b are located on the lower side in the vertical direction.

  The tapered surface 26d is formed on one end surface in the long side direction of each upright portion 26b. The taper surface 26d is formed on a surface facing the tightening end portions 21k and 21l of the annular portions 21a and 21b on the other end side of the annular portions 21a and 21b, that is, the side where the screwing portion 24c is located. A contact surface that contacts the end portions 21k and 21l is formed. Then, each tapered surface 26d is formed so that the fastening nut 25 and the shaft portion are formed when the bracket 26 together with the fastening nut 25 approaches the shaft portion 24a side along the axial direction along with the rotation of the fastening nut 25 around the axial direction. The axial direction tightening force generated with respect to 24a is inclined in a direction to convert the annular portions 21a and 21b into a pressing force in the annular portion width direction that presses the annular portions 21b toward the contact portion 24b side in the annular portion width direction. . Here, each taper surface 26d is inclined with respect to the axial direction. More specifically, each taper surface 26d is gradually removed from the tightening end portions 21k and 21l as it is separated from the base portion 26a side in the axial direction in a state where the bracket 26 is assembled to the screwing portion 24c. It is formed as an inclined surface that separates (in other words, an inclined surface in which the width along the annular portion width direction of each upright portion 26b gradually decreases).

  Further, the annular portions 21a and 21b of the present embodiment are in contact with the bracket 26 on the other end side in the annular portion width direction, that is, on the side where the screwing portion 24c is located at the tightening end portions 21k and 21l (screwing). The guide portion 21p is provided on the end surface on the side facing the portion 24c. The guide portion 21p regulates the rotation of the bracket 26 around the axial direction and guides the movement of the bracket 26 along the axial direction. The guide portion 21p is formed in each of the tightening end portions 21k and 21l as a notch portion into which each tapered surface 26d of the bracket 26 is inserted (see FIG. 2 and the like). Here, each guide portion 21p is formed in a shape corresponding to the inclination of the tapered surface 26d. That is, each guide portion 21p is provided with a pair corresponding to each tapered surface 26d at the tightening end portion 21k, and a pair corresponding to each tapered surface 26d at the tightening end portion 21l. Each guide portion 21p has a guide portion 21p in which the notch amount (depth along the annular portion width direction) of the guide portion 21p formed on the tightening end portion 21k side is formed on the tightening end portion 21l side. It is formed to be larger than the notch amount. Each guide portion 21p can guide the movement of the bracket 26 along the axial direction by restricting the rotation of the bracket 26 around the axial direction by inserting each tapered surface 26d.

  In the battery terminal 1 configured as described above, in the state where the L-shaped bolt 24 is assembled to the main body portion 21, the contact portion 24b has the tightening end portions 21k and 21l of the annular portions 21a and 21b in the width direction of the annular portion. One side engages with the notches 21m and 21n, and the screwing portion 24c is positioned on the other side in the width direction of the annular portion of the tightening end portions 21k and 21l. It faces the side (vertical upper side). The battery terminal 1 is assembled with the bracket 26 in the threaded portion 24c in such a positional relationship that the threaded portion 24c is inserted into the penetrating portion 26c of the bracket 26 and each tapered surface 26d is positioned in the guide portion 21p. In the battery terminal 1, the fastening nut 25 is assembled to the screwing portion 24c in such a positional relationship that the bracket 26 is interposed between the shaft portion 24a of the L-shaped bolt 24 and the fastening nut 25 with respect to the axial direction. . The battery terminal 1 is assembled to the battery post 51 by inserting the battery post 51 into the post insertion holes 21f and 21g in such a positional relationship that the shaft portion 22a of the stud bolt 22 is exposed. The battery terminal 1 is tightened from one side in the axial direction, here the upper side in the vertical direction, with the inner peripheral surfaces of the post insertion holes 21f and 21g and the outer peripheral surface of the battery post 51 in contact with each other. Thus, both sides of the tightening end portions 21k and 21l of the annular portions 21a and 21b are tightened in the approaching direction with the slits 21h and 21i interposed therebetween, thereby being fastened to the battery post 51.

  More specifically, in the battery terminal 1, the fastening nut 25 is rotated around the axial direction (screwing portion 24c) by a tool or the like, so that the fastening nut 25 is moved to the other side in the axial direction by the screwing action. Move vertically down. In the battery terminal 1, the bracket 26 also moves to the other side in the axial direction along with the movement of the fastening nut 25 toward the other side in the axial direction (downward in the vertical direction), and approaches the shaft part 24 a side of the L-shaped bolt 24. At this time, the bracket 26 is guided to move along the axial direction while the rotation around the axial direction is restricted by the guide portion 21p formed at the tightening end portions 21k and 21l. In the battery terminal 1, as the bracket 26 moves in the axial direction, each tapered surface 26d formed on the bracket 26 comes into contact with the tightening end portions 21k and 21l of the annular portions 21a and 21b. When the bracket 26 approaches the shaft portion 24a along the axial direction along with the rotation of the fastening nut 25 along with the rotation of the fastening nut 25, the battery terminal 1 is connected to the fastening nut 25 and the shaft portion 24a by the action of each tapered surface 26d. The axial tightening force generated between the annular portions 21a and 21b presses the annular portions in the width direction of the annular portions 21a and 21b, in other words, the interval between the slits 21h and 21i. It is converted into a pressing force in the direction of reduction (see arrow A in FIG. 5). Thereby, the battery terminal 1 is pressed by the annular portions 21a, 21b toward the contact portion 24b in the annular portion width direction by the pressing force in the annular portion width direction from each tapered surface 26d. At this time, the contact portion 24b functions as a reaction force member that receives the reaction force of the pressing force by each tapered surface 26d. As a result, the battery terminal 1 is pressed in the direction in which the tightening end portions 21k and 21l of the annular portions 21a and 21b reduce the interval between the slits 21h and 21i by the pressing force of each tapered surface 26d, and the slits 21h and 21i. The interval of becomes narrower.

  Accordingly, the battery terminal 1 is formed so that the gap between the slits 21h and 21i is narrowed by the pressing force generated by the conversion and generation of the tapered surface 26d with the rotation of the fastening nut 25, so that the inner peripheral surface of the post insertion holes 21f and 21g The diameters of the post insertion holes 21 f and 21 g are reduced in a state where the outer peripheral surface of the battery post 51 is in contact with the battery post 51 and fastened to the battery post 51. The battery terminal 1 is electrically connected to a shaft portion 22a of the stud bolt 22 with a metal fitting provided at the end of the electric wire. On the other hand, in the battery terminal 1, when the fastening nut 25 is rotated in the reverse direction, the pressing force by each tapered surface 26d is weakened, the interval between the slits 21h and 21i is widened, and the diameters of the post insertion holes 21f and 21g are enlarged. The battery post 51 can be removed.

  According to the battery terminal 1 described above, the annular portions 21a and 21b in which the post insertion holes 21f and 21g into which the battery post 51 is inserted and the slits 21h and 21i continuous with the post insertion holes 21f and 21g are formed. A slit 21h from one end side of the annular portions 21a, 21b along the annular width direction, which is a direction intersecting the axial direction along the central axis X of the battery post 51 and intersecting the slits 21h, 21i. The annular portion 21a, 21b is disposed so as to extend to the other end side of the annular portion 21a, and an abutting portion 24b that contacts the annular portions 21a, 21b is provided on one end side in the annular portion width direction. An L-shaped bolt 24 provided with a threaded portion 24c that is bent along the axial direction on the other end side in the direction and formed with a threaded groove 24d; And the other end of the annular portions 21a and 21b provided to be movable along the axial direction of the fastening nut 25 along with the movement of the fastening nut 25 along the axial direction. The axial tightening force generated between the fastening nut 25 and the width direction member as the fastening nut 25 rotates around the axial direction is brought into contact with the annular portions 21a and 21b on the side, and the contacting portion 24b. A bracket 26 for converting the pressing force in the annular portion width direction to press the annular portions 21a and 21b in the direction of reducing the interval between the slits 21h and 21i of the annular portions 21a and 21b along the annular portion width direction. Prepare.

  Therefore, the battery terminal 1 causes the bracket 26 to apply the axial tightening force generated by the rotation of the fastening nut 25 around the axial direction by the action of the bracket 26 and the bracket 26. The annular portions 21a, 21b can be fastened to the battery post 51 by converting the pressure between the slits of the annular portions 21a, 21b to a pressing force in the annular portion width direction. That is, for example, the battery terminal 1 does not have to secure a work space for rotating by setting a tool for rotating the fastening nut 25 on the side of the battery post 51, that is, on the side of the battery 50. The tool can be set and operated from one side (for example, the upper side in the vertical direction) of the battery post 51, which is relatively easy to take up a work space. As a result, the battery terminal 1 can improve workability when fastened to the battery post 51 even when it is difficult to secure a work space around the battery 50, for example.

  More specifically, according to the battery terminal 1 described above, the L-shaped bolt 24 is formed in the annular portions 21a and 21b with the slits 21h and 21i sandwiched from one end side of the annular portions 21a and 21b along the annular portion width direction. The shaft 26a has a shaft portion 24a which penetrates to the other end side of the ring portion and is provided with a contact portion 24b on one end side in the annular portion width direction and a screwing portion 24c on the other end side in the annular portion width direction. The through portion 26c into which the threaded portion 24c is inserted along the direction, and the fastening with the rotation of the fastening nut 25 around the axial direction in contact with the annular portions 21a and 21b on the other end side of the annular portions 21a and 21b When the bracket 26 together with the nut 25 approaches the shaft portion 24a side along the axial direction, the annular portion 21a, 21b is annularly formed by the axial tightening force generated between the fastening nut 25 and the shaft portion 24a. Contact portion 24 in the width direction And a tapered surface 26d inclined in a direction to convert the pressing force of the annular portion width direction of pressing to the side. Therefore, the battery terminal 1 uses the axial tightening force generated between the fastening nut 25 and the L-shaped bolt 24 as the fastening nut 25 rotates in the axial direction between the contact portion 24 b and the bracket 26. It is possible to realize a configuration in which the pressure is converted into a pressing force in the annular portion width direction that presses the annular portions 21a and 21b in a direction in which the interval between the slits 21h and 21i is reduced along the annular portion width direction.

  Further, according to the battery terminal 1 described above, the annular portions 21a and 21b are formed in a portion that contacts the bracket 26 on the other end side in the annular portion width direction, and restricts the rotation of the bracket 26 around the axial direction. In addition, a guide portion 21p for guiding the movement of the bracket 26 along the axial direction is provided. Therefore, when the bracket 26 moves along the axial direction in accordance with the movement of the fastening nut 25 along the axial direction, the battery terminal 1 is moved by the guide portion 21p formed at the fastening end portions 21k and 21l. The movement of the bracket 26 along the axial direction is guided while the rotation of the bracket 26 is restricted. As a result, since the battery terminal 1 can appropriately hold the position of the bracket 26, a stable tightening position can be ensured, so that the workability at the time of fastening to the battery post 51 is also improved in this respect. be able to. In this case, the battery terminal 1 has the guide portion 21p that can be integrated into the fastening ends 21k and 21l of the annular portions 21a and 21b, so that, for example, the number of parts constituting the battery terminal 1 can be reduced. Can be suppressed, and the manufacturing cost can be suppressed.
