That is, the first taper surface 28a is an end portion of the taper nut 28 in the annular portion width direction of the annular portions 24a and 25a on the side where the fastening member support portion 26c and the fastening bolt 27 are provided, and the annular portion. It is formed on the surface facing in the width direction. The first taper surface 28a of the present embodiment is formed at a position where it can contact a part of the annular portions 24a, 25a, here, the plate-like protruding portion 25e of the annular portion 25a. Further, the taper nut 28 is provided with a second taper surface 28b (see FIG. 5 and the like) on the back side of the first taper surface 28a with respect to the annular portion width direction. The tapered shapes of the first tapered surface 28a and the second tapered surface 28b will be described in detail later.

  The rotation stopper 29 restricts the rotation of the taper nut 28 around the axial direction. The rotation stopper 29 of the present embodiment is configured to include a through hole 26f (see FIGS. 2, 5, etc.) formed in the holding member 26. The through hole 26f is formed so as to penetrate in the axial direction on the end portion side of the opposing receiving portion 26e on the fastening member support portion 26c side in the annular portion width direction. The through hole 26f is formed in a rectangular shape. The through hole 26f is formed at a position substantially opposite to the long hole 26d of the fastening member support portion 26c with respect to the axial direction. The rotation stopper 29 accommodates the taper nut 28 in the through hole 26f and restricts the rotation of the taper nut 28 around the axial direction. The second tapered surface 28b described above contacts the edge of the through hole 26f in a state where the taper nut 28 is accommodated in the through hole 26f. The second tapered surface 28b is an edge of the through hole 26f and abuts on an edge on the opposite side of the annular part 24a, 25a side in the annular part width direction.

  The first tapered surface 28a of the present embodiment has the taper nut 28 along the axial direction as the fastening bolt 27 rotates around the axial direction in a state where the rotation of the taper nut 28 is restricted by the rotation stop portion 29. When approaching the fastening bolt 27 side, the clamping force generated between the fastening bolt 27 and the taper nut 28 is applied to a pressing force that presses the annular portions 24a, 25a toward the annular portion holding portion 26b in the annular portion width direction. It has a slope in the direction of conversion. Here, the 1st taper surface 28a has the inclination that the width | variety of the annular part width direction of the taper nut 28 spreads gradually as it separates from the head 27b side of the fastening bolt 27 along an axial direction. As a result, the first tapered surface 28a is configured so that the tightening force generated between the fastening bolt 27 and the taper nut 28 when the taper nut 28 approaches the fastening bolt 27 side as the fastening bolt 27 rotates, 24a and 25a can be converted into a pressing force that presses the annular portion holding portion 26b.

  Further, in the second tapered surface 28b of the present embodiment, the taper nut 28 is moved along the axial direction along with the rotation of the fastening bolt 27 around the axial direction in a state where the rotation of the taper nut 28 is restricted by the rotation stop portion 29. When approaching the fastening bolt 27 side, the fastening force generated between the fastening bolt 27 and the taper nut 28 is applied to the annular portion holding portion 26b of the holding member 26 via the edge of the through hole 26f. It has an inclination in the direction to convert it into the attractive force attracted to the taper nut 28 side. Here, the 2nd taper surface 28b has the inclination that the width | variety of the annular part width direction of the taper nut 28 spreads gradually as it separates from the head 27b side of the fastening bolt 27 along an axial direction. As a result, the second tapered surface 28b allows the annular portion to generate a tightening force generated between the fastening bolt 27 and the taper nut 28 when the taper nut 28 approaches the fastening bolt 27 side as the fastening bolt 27 rotates. The holding portion 26b can be converted into an attractive force that attracts the taper nut 28 side.

  That is, as shown in FIG. 5 and the like, the taper nut 28 according to the present embodiment is formed by the first taper surface 28a and the second taper surface 28b as viewed from the axial direction and the direction orthogonal to the annular portion width direction. It is formed in a trapezoidal shape such that the width in the annular portion width direction gradually increases as the distance from the head 27b side of the fastening bolt 27 increases along the direction.

  Further, the battery terminal 1 of the present embodiment further includes a positioning mechanism 30. The positioning mechanism 30 includes a protruding claw portion 24h formed on one of the annular portions 24a, 25a or the connecting portion 26a, here, the plate-like protruding portion 24e of the annular portion 24a, and the annular portions 24a, 25a, or the connecting portion. 26a has a notch 26g formed in the connecting portion 26a. As described above, the protruding claw portion 24h is formed by bending the tip of the plate-like protruding portion 24e upward in the vertical direction (axial direction). A total of two protruding claw portions 24h are provided, one for each of the pair of plate-like protruding portions 24e divided by the slit 24d. The notch 26g is formed as a recess-shaped notch on the side of the connecting portion 26a along the annular portion width direction and on the tip side of the plate-like protrusion 24e. The positioning mechanism 30 is configured such that the protrusion claw portion 24h and the notch portion 26g engage with each other in a state where the holding member 26 is assembled to the annular portions 24a and 25a, thereby holding the holding member 26 with respect to the annular portions 24a and 25a. 26 can be positioned at a predetermined position.

  In the battery terminal 1 configured as described above, the holding member 26 is assembled to the plate-like protrusion 24e and the plate-like protrusion 25e, so that the upper divided body 24 and the lower divided body 25 of the main body 21 are integrated. It becomes. In this state, the battery terminal 1 is inserted into the elongated hole 26d of the fastening member support portion 26c of the holding member 26 and supported at a predetermined position, and the taper nut 28 is inserted into the through hole of the rotation stop portion 29. It is screwed onto the shaft portion 27a of the fastening bolt 27 while being accommodated in the 26f. The battery terminal 1 is placed in a post-position relationship such that the shaft portion 22a of the stud bolt 22 is exposed in a state where the upper divided body 24 and the lower divided body 25 are integrated by the holding member 26 as described above. When the battery post 51 is inserted into the insertion hole 24 c and the post insertion hole 25 c, the battery post 51 is assembled. The battery terminal 1 is tightened from the upper side in the vertical direction (axial direction) with the post insertion hole 24 c and the inner peripheral surface of the post insertion hole 25 c in contact with the outer peripheral surface of the battery post 51. The both sides of the annular portions 24a and 25a are tightened in the approaching direction with the slits 24d and 25d interposed therebetween, thereby being fastened to the battery post 51.

  More specifically, as shown in FIG. 6, the battery terminal 1 has the head 27b of the fastening bolt 27 in the axial direction (shaft portion 27a) with a tool or the like in a state where the rotation of the taper nut 28 is restricted by the rotation stop portion 29. ), The taper nut 28 approaches the head 27b side of the fastening bolt 27 along the axial direction while the axial position of the fastening bolt 27 remains unchanged. In the battery terminal 1, when the taper nut 28 approaches the head 27b side of the fastening bolt 27 as the fastening bolt 27 rotates, the first taper surface 28a formed on the taper nut 28 has the annular portions 24a and 25a. It is in contact with the end portion in the width direction opposite to the end portion held by the annular portion holding portion 26b. Here, the 1st taper surface 28a contact | abuts to the plate-shaped protrusion part 25e of the cyclic | annular part 25a. In addition, when the taper nut 28 approaches the head 27b side of the fastening bolt 27 as the fastening bolt 27 rotates, the second tapered surface 28b formed on the taper nut 28 becomes the edge of the through hole 26f. Abuts against the part. Here, the 2nd taper surface 28b contact | abuts the edge part of the through-hole 26f, and the edge part on the opposite side to the annular parts 24a and 25a side with respect to the annular part width direction.

  When the taper nut 28 comes closer to the head 27b side of the fastening bolt 27 as the fastening bolt 27 rotates, the battery terminal 1 receives a fastening force generated between the fastening bolt 27 and the taper nut 28. The first tapered surface 28a converts the annular portions 24a and 25a into a pressing force that presses the annular portions 24a and 25a toward the annular portion holding portion 26b in the annular portion width direction. Thereby, as for battery terminal 1, annular parts 24a and 25a are pressed by the pressing force by the 1st taper surface 28a to the annular part holding part 26b side of the annular part width direction. At this time, the annular portion holding portion 26b functions as a reaction force member that receives the reaction force of the pressing force by the first tapered surface 28a. As a result, the battery terminal 1 is pressed by the pressing force by the first taper surface 28a, together with the plate-like protruding portion 24e of the annular portion 24a and the plate-like protruding portion 25e of the annular portion 25a toward the annular portion holding portion 26b. The interval between the slits 24d and 25d is reduced.

  At this time, the battery terminal 1 is tightened between the fastening bolt 27 and the taper nut 28 when the taper nut 28 further approaches the head 27b side of the fastening bolt 27 as the fastening bolt 27 rotates. The force is converted by the second tapered surface 28b into an attractive force that attracts the annular portion holding portion 26b of the holding member 26 toward the tapered nut 28 in the annular portion width direction via the edge portion of the through hole 26f. As a result, the battery terminal 1 is attracted to the annular portions 24a and 25a in the annular portion width direction by the annular portion holding portion 26b by the attractive force of the second tapered surface 28b. At this time, the holding member 26 and the fastening bolt 27 relatively move along the annular portion width direction. However, since the fastening bolt 27 is inserted into the long hole 26d formed in the holding member 26, the annular portion Relative movement along the width direction is not hindered. As a result, in the battery terminal 1, the distance between the slits 24d and 25d formed in the plate-like projecting portions 24e and 25e of the annular portions 24a and 25a is narrowed also by the attractive force by the second tapered surface 28b.

  Therefore, the battery terminal 1 has the post 24 because the interval between the slits 24d and 25d is reduced by the pressing force of the first tapered surface 28a and the attractive force of the second tapered surface 28b as the fastening bolt 27 rotates. The diameters of the post insertion hole 24 c and the post insertion hole 25 c are reduced and fastened to the battery post 51 in a state where the inner peripheral surface of the insertion hole 24 c and the post insertion hole 25 c is in contact with the outer peripheral surface of 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.

  At this time, the battery terminal 1 is rotated because the projection claw 24h and the notch 26g constituting the positioning mechanism 30 are engaged with each other and the holding member 26 is reliably positioned with respect to the annular portions 24a and 25a. In a state where the rotation of the taper nut 28 is restricted by the stop portion 29, it is possible to suppress the displacement of the holding member 26 with the rotation of the fastening bolt 27.

  As described above, when the battery terminal 1 is fastened to the battery post 51, the taper nut 28 approaches the fastening bolt 27 side as the fastening bolt 27 rotates, while the fastening bolt 27 itself is positioned in the axial direction. Remains fixed. As a result, the battery terminal 1 is configured such that the fastening bolt 27 is tightened from the upper side in the axial direction, and the relative position in the axial direction of the fastening bolt 27 is not changed when the fastening bolt 27 is tightened. be able to. Therefore, when the battery terminal 1 is fastened to the battery post 51, even if the fastening bolt 27 is fastened from the upper side in the axial direction, the change in the fastening height of the fastening bolt 27 is suppressed. The positional relationship that facilitates the tightening operation can be maintained, and the workability at the time of fastening to the battery post 51 can be improved.

  On the other hand, in the battery terminal 1, when the fastening bolt 27 is rotated in the reverse direction, the pressing force by the first tapered surface 28a and the attracting force by the second tapered surface 28b are weakened, and the interval between the slits 24d and 25d is reduced. The diameter of the post insertion hole 24c and the post insertion hole 25c is enlarged, and the battery post 51 can be removed.

  The battery terminal 1 described above includes the annular portions 24a and 25a in which the post insertion holes 24c and 25c and the slits 24d and 25d are formed, the connecting portion 26a, the annular portion holding portion 26b, and the fastening member support portion 26c. The holding member 26, the fastening bolt 27 supported by the fastening member support portion 26c at a predetermined position along the axial direction, the taper nut 28 formed with the first taper surface 28a, and the rotation stopper for restricting the rotation of the taper nut 28 Part 29. Therefore, the battery terminal 1 generates a tightening force generated between the fastening bolt 27 and the taper nut 28 by the action of the fastening bolt 27, the taper nut 28, the rotation stopper 29, and the first taper surface 28a. The annular portions 24 a and 25 a can be fastened to the battery post 51 by converting the pressing force to press the 25 a in the annular portion width direction. At this time, the battery terminal 1 is configured so that the fastening bolt 27 is tightened from the upper side in the axial direction, and the relative position in the axial direction of the fastening bolt 27 is not changed when the fastening bolt 27 is tightened. Therefore, it is possible to maintain a positional relationship that facilitates the tightening operation of the fastening bolt 27, and it is possible to improve workability at the time of fastening to the battery post 51.
