  As shown in FIGS. 4 and 5, the covering member 12 is formed by bending a plate member formed of an integral metal material into two, and thereby the upper plates facing each other in the vertical direction while having a predetermined interval. The part 121 and the lower plate part 122 are formed. The upper plate portion 121 and the lower plate portion 122 are respectively provided with an upper engagement hole 123 and a lower engagement hole 124 that engage with the battery post BP by performing burring. The inner diameters of the upper engagement hole 123 and the lower engagement hole 124 are set larger than the outer diameter of the battery post BP at each mounting position when the mounting to the battery post BP is completed.

  The upper engagement hole 123 and the lower engagement hole 124 are provided so as to be aligned with a tightening hole 126 described later, and the inner peripheral surface thereof is formed in a tapered shape in accordance with the shape of the outer peripheral surface of the battery post BP. These centers are shifted from each other in the longitudinal direction of the covering member 12, and the center of the upper engagement hole 123 is located on the tightening hole 126 side with respect to the center of the lower engagement hole 124. Further, both end portions 125 of the plate member are stacked and fixed to each other, and a tightening hole 126 passes therethrough. The tightening hole 126 is for inserting the weld bolt 111 as will be described later, and has an inner diameter larger than the outer diameter of the weld bolt 111. The nut 13 is a normal one in which an internal thread is formed in its inner hole to be screwed with the weld bolt 111.

  Next, a method for attaching the battery terminal 10 according to the present embodiment to the battery post BP will be described with reference to FIGS. First, the cable fitting member 11 in which the cable attachment portion 116 is caulked to the core wire CW of the battery cable BC is placed on the battery BT by engaging the post mounting hole 113 of the annular portion 112 with the battery post BP.

  Thereafter, the lower end portion of the covering member 12 opposite to the tightening hole 126 of the lower plate portion 122 abuts on the cable fitting member 11, and the inner peripheral surface of the lower engagement hole 124 is tightened. The battery post is brought into contact with the middle of the tapered outer peripheral surface of the battery post BP so that the part located on the hole 126 side is disposed above the part located on the side opposite to the fastening hole 126. Lock diagonally to BP. At the same time, after the weld bolt 111 is inserted into the tightening hole 126, the nut 13 is screwed into the weld bolt 111 (shown in FIG. 6).

There is no contact.

  When the nut 13 screwed into the weld bolt 111 is rotated and tightened downward, the end portion 125 of the covering member 12 is pushed downward by the nut 13. Since the lower plate portion 122 is in contact with the cable fitting member 11 at the lower end thereof and cannot move further downward, only the end portion 125 moves downward, and the inner periphery of the lower engagement hole 124 is While the part located on the tightening hole 126 side of the surface is in contact with the outer peripheral surface of the battery post BP, the covering member 12 changes its posture clockwise in FIG. 6 and approaches the horizontal state. At this time, a portion of the inner peripheral surface of the upper engagement hole 123 located on the side opposite to the fastening hole 126 gradually approaches the outer peripheral surface of the battery post BP (shown in FIG. 7).

  When the position of the covering member 12 is changed, the inner diameter of the tightening hole 126 of the covering member 12 is sufficiently larger than the outer diameter of the weld bolt 111, so that the weld bolt 111 and the tightening hole 126 interfere with each other. There is no. Further, since both side surfaces of the covering member 12 are locked to the guide rods 115 of the cable fitting member 11, when the nut 13 is rotated, the rotational force of the nut 13 becomes a frictional force, and the covering member 12 is rotated. Even if a rotational moment centered on the weld bolt 111 is generated in the covering member 12 by being transmitted to the end portion 125, the guide member 115 prevents the covering member 12 from rotating.

  Further, when the nut 13 is rotated and tightened downward, the end portion 125 of the covering member 12 is further pushed downward, and eventually the covering member 12 becomes horizontal, and the cable fitting member 11 and the covering member 12. Are fastened to each other in the vertical direction. In this state, a portion of the inner peripheral surface of the upper engagement hole 123 located on the side opposite to the tightening hole 126 and a portion of the inner peripheral surface of the lower engagement hole 124 located on the tightening hole 126 side. Thus, the battery terminal 10 is clamped on the outer peripheral surface of the battery post BP and the centers of the upper engagement hole 123 and the lower engagement hole 124 are shifted in opposite directions with respect to the axis of the battery post BP. Is mounted on the battery post BP (shown in FIG. 8). At this time, since the annular portion 112 of the cable fitting member 11 and the lower end portion of the covering member 12 come into contact with each other, the cable fitting member 11 and the covering member 12 can no longer approach each other in the vertical direction. A predetermined axial force is generated and fixed between the nut 13 and the nut 13.

  In the present embodiment, the cable fitting member 11 and the covering member 12 are locked to the battery post BP, the posture of the covering member 12 with respect to the cable fitting member 11 is changed, and then fastened to each other in the vertical direction. The center of the upper engagement hole 123 and the lower engagement hole 124 is shifted in opposite directions to the battery terminal 10 to be mounted on the battery post BP, so that the covering member 12 is a cable fitting member. 11 can be tightened in the vertical direction, and the workability of mounting on the battery post BP can be improved.
