  However, in the conventional bolt fastening structure of the terminal 60, since the terminal 60 set on the terminal installation portion 51 of the bracket 50 can be easily moved until it is fastened with a bolt (not shown), the terminal 60 is attached to the bracket 50. It is easier to drop off than the terminal installation part 51. When the terminal 60 drops off from the terminal installation part 51 of the bracket 50, it is necessary to redo the setting work of the terminal 60 to the bracket 50, and there is a problem that workability is poor. In particular, the fastening operation of the terminal 60 to a transmission for an automobile or the like is forced to work in a very narrow space, so that improvement in workability is desired.

  Here, it is conceivable that an uneven means for completely positioning the terminal 60 is attached to the terminal installation portion 51 of the bracket 50 (see Patent Document 1). However, if positioning uneven means is provided, the structure of the bracket 50 becomes very complicated, and the setting work of the terminal 60 to the bracket 50 becomes very troublesome, and the workability is worsened. Absent.

  Therefore, the present invention has been made to solve the above-described problems, and an object of the present invention is to provide a terminal bolt fastening structure with good workability to fasten the terminal to the bracket together.

The present invention includes a terminal connected to an electric wire and having a bolt hole, a terminal installation part provided with a bolt hole, a rotation preventing part and a banding part for restricting rotation of the terminal set in the terminal installation part. A bracket having a band-hanging portion, and being fixed to the bracket by being hung on the band-hanging portion and arranged so as to surround the periphery of the terminal, allowing the terminal to move on the terminal installation portion, and the terminal installation It is the terminal bolt fastening structure provided with the drop-off prevention band for restricting movement so as not to drop off from the part.

  It is preferable that the anti-rotation part also serves as a part of the banding part.

  According to the present invention, the terminal set in the terminal installation part of the bracket is restricted from moving out of the terminal installation part by the drop prevention band, so that the terminal may fall out of the terminal installation part. As a result, there is no need to re-set the terminal to the bracket. In addition, since the terminal set in the bracket terminal installation part is fixed with a drop-off prevention band, it can be moved a little. Therefore, if both bolt holes are misaligned, it can be easily positioned when passing the bolt. Can be combined. From the above, the workability of fixing the terminal to the bracket by fastening is good.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  As shown in FIGS. 1 and 2, the bolt fastening structure of the terminal 1 includes a terminal 1, a bracket 10 that fixes the terminal 1, and a wire harness binding that is a fall-off prevention band that temporarily holds the terminal 1 on the bracket 10. And a bolt (not shown) for fastening the terminal 1 to the bracket 10.

  The terminal 1 is a round terminal (LA terminal). The terminal 1 has an electric wire connection part 2 and a bolt fastening part 3. The wire connection portion 2 is fixed to the end portion of the wire W by caulking. A bolt hole 4 is provided in the bolt fastening portion 3.

  The bracket 10 is attached to the automobile transmission. The bracket 10 is formed by punching and bending a single conductive metal material. The bracket 10 includes a terminal installation part 11, a rotation stopper 12, and one band hook 13. The terminal installation part 11 is provided with a band insertion hole 11 a and a bolt hole 14. The band insertion hole 11 a is provided almost directly below the band-hanging recess 12 c of the rotation stopper 12.

  The anti-rotation part 12 includes a standing part 12a erected from the side end of the terminal installation part 11, and an upper restriction part 12b bent from the upper end of the erection part 12a to the upper surface side of the terminal installation part 11. It is formed in a substantially U shape. The other band hanging recess 12c is formed at the tip of the upper restricting portion 12b. That is, in this embodiment, the rotation stopper 12 also serves as the other band locking portion.

  One band latching portion 13 is provided at a position farther from the rotation preventing portion 12 with respect to the bolt hole 14 and at the side end of the terminal installation portion 11 on the same side as the rotation preventing portion 12. The band hooking portion 13 is formed of a standing portion 13a that is erected from the terminal installation portion 11, and an upper surface portion 13b that is bent from the upper end of the erection portion 13a to the side opposite to the terminal installation portion 11. Has been. One banding recess 13c is provided at the tip of the upper surface portion 13b.

  The wire harness binding band 20 is made of, for example, a synthetic resin, and is originally for binding a plurality of electric wires W. The wire harness binding band 20 is configured to bind both ends with a desired constraint dimension. The wire harness binding band 20 is fixed to the bracket 10 by binding both ends of the wire harness binding band 20 in a state of being hung on both band hanging recesses 12c and 13c of the bracket 10 on which the terminal 1 is disposed. The wire harness binding band 20 is temporarily held so that the terminal 1 does not come out of the opening of the rotation preventing portion 12 and fall off from the terminal installation portion 11.

  A bolt (not shown) is passed through the bolt holes 4 and 14 of both the terminal 1 and the bracket 10, and the terminal 1 and the bracket 10 are fastened together.

  Next, fixing work of the terminal 1 to the bracket 10 will be described. First, the terminal 1 is set in the terminal installation part 11.

  Next, the wire harness binding band 20 is hooked on the two band hooking recesses 12c and 13c of the bracket 10 and both ends thereof are bound through the band insertion hole 11a, and the wire harness binding band 20 is attached to the bracket 10. Fix it. Thereby, the terminal 1 is temporarily held by the terminal installation part 11 of the bracket 10 by the wire harness binding band 20. Specifically, the terminal 1 is allowed to move somewhat, but the movement is restricted so that it does not fall off from the terminal installation part 11.

  Next, a bolt (not shown) is passed through the bolt holes 4 and 14 of both the terminal 1 and the bracket 10. Here, when both the bolt holes 4 and 14 are displaced, the position of the terminal 1 is corrected so that the both bolt holes 4 and 14 coincide with each other, and then both the bolt holes 4 are aligned. , 14 is passed through a bolt (not shown). Then, a bolt (not shown) passed through both bolt holes 4 and 14 is tightened, and the terminal 1 and the bracket 10 are fastened together with the fastening force of the bolt (not shown). During the bolt tightening operation, the rotation stop portion 12 prevents the terminal 1 from being rotated.

  As described above, the bolt fastening structure of the terminal 1 is connected to the electric wire W, the terminal 1 having the bolt hole 4, the terminal installation part 11 provided with the bolt hole 14, and the detent that restricts the rotation of the terminal 1. A bracket 10 having a portion 12 and a band hanging portion 13 and a wire harness binding band 20 that restricts the movement of the terminal 1 so as not to drop off from the terminal installation portion 11 are provided. Therefore, since the terminal 1 set in the terminal installation part 11 of the bracket 10 does not fall off from the terminal installation part 11, a situation in which the setting work of the terminal 1 to the bracket 10 is not repeated as in the conventional example. Further, since the terminal 1 set in the terminal installation portion 11 of the bracket 10 can be moved a little, if both bolt holes 4 and 14 are in a misaligned state, a bolt (not shown) is passed. Can be easily aligned. From the above, the workability of fixing the terminal 1 to the bracket 10 by fastening together is good.

  Since the rotation preventing part 12 has the upper restricting part 12 b together with the standing part 12 a, the rotation preventing part 12 is arranged so as to cover the periphery of the terminal 1, and therefore, other members come into contact with the terminal 1. It is possible to prevent the terminal 1 to be damaged as much as possible. In addition, in this embodiment, since the banding portion 13 is also disposed around the terminal 1, damage to the terminal 1 can be further effectively prevented.

  In this embodiment, the detent portion 12 also serves as one of the band hanging portions. Therefore, it is possible to prevent the structure of the bracket 10 from becoming complicated as much as possible. Of course, the other banding portion may be additionally provided without using the rotation stopper 12 as the banding portion. Moreover, the banding part 13 may be only one place instead of two places.

  In this embodiment, the drop prevention band uses the wire harness binding band 20, so there is no need to separately prepare a dedicated band for temporarily holding the terminal 1 on the terminal installation portion 11.

  In this embodiment, the terminal 1 is applied to a bolt fastening structure that fixes the terminal 1 to the bracket 10 of the automobile transmission.

  In this embodiment, the terminal 1 is a round terminal, but the present invention is applicable as long as it has a bolt hole.
