When the nut 5 is accommodated between the second connection portion 63 and the rear end portion 75, the nut 5 is sandwiched between the second connection portion 63 and the housing 7.

As shown in FIG. 2, in the LA terminal 3, a terminal connection portion 31 connected to the male terminal 6 and an electric wire connection portion 32 connected to the electric wire 4 are provided continuously in the left-right direction. The terminal connection portion 31 is provided in a plate shape, and is provided with a bolt through hole 33 through which the bolt 9 penetrating in the front-rear direction passes. In the present embodiment, as shown in FIGS. 4 and 5, the LA terminals 3 are fastened to the male terminals 6 of the connector 2 by bolts such that the leading-out directions of the two electric wires 4 are on the left side.

Next, a more detailed configuration of the housing 7 described above will be described. As shown in FIGS. 6 and 7, at the rear end portion 75, the lower side of the first wall portion 76 is provided to further protrude rearward than the upper side of the first wall portion 76. Further, the second wall portion 771 standing downward from the first wall portion 76 is provided behind the second wall portion 772 standing upward from the first wall portion 76.

As shown in FIGS. 4 and 5, the second wall portion 771 described above stands upward and downward from the first wall portion 76 and covers the LA terminal 3 on the lower side. The second wall portion 771 is provided so as to stand from the left end of the first wall portion 76, and is provided so as to cover the electric wire 4 side beyond a portion of the LA terminal 3 on the lower side on which the bolt 9 is overlapped. Accordingly, the second wall portion 771 does not interfere with a bolt fastening work. In addition, a lower end of the second wall portion 771 is not connected to the third wall portion 781 and the second wall portion 771 is provided away from the third wall portion 781.

The second wall portion 772 described above stands upward from the first wall portion 76 and covers the LA terminal 3 on the upper side. An upper end of the second wall portion 772 is connected to a left end of the third wall portion 782. The second wall portion 772 is also provided so as to cover the electric wire 4 side beyond a portion of the LA terminal 3 on the upper side on which the bolt 9 is overlapped. Accordingly, the second wall portion 772 does not interfere with the bolt fastening work. As shown in FIG. 8, the first wall portion 76 has a notch 761 at a left end thereof. The notch 761 is provided between a lower side of the first wall portion 76 and the second wall portion 771 at the rear end portion 75.

Next, as shown in FIG. 4, a procedure of connecting the connector 2 disposed on the upper side and the other product 100 disposed on the lower side by the electric wire 4 will be described. As shown in FIG. 4, the LA terminals 3 are connected to both ends of the electric wire 4. The LA terminal 3 connected to one end of the electric wire 4 is fastened to the male terminal 6 of the connector 2 by a bolt, and the LA terminal 3 connected to the other end of the electric wire 4 is fastened to the other product 100 by a bolt. The electric wire 4 connected to the male terminal 6 on the lower side is bent more than the electric wire 4 connected to the male terminal 6 on the upper side.

First, the LA terminal 3 is overlapped with the male terminal 6 on the lower side of the connector 2 from between the second wall portion 771 and the third wall portion 781 with the electric wire 4 facing leftward. Next, the LA terminal 3 connected to the other end of the electric wire 4 is bent toward the right side, and is overlapped on a side surface of the other product 100 perpendicular to the up-down direction and fastened by a bolt. The LA terminal 3 on the other product 100 side is fastened to the front side of the LA terminal 3 on the connector 2 side. Therefore, due to a force of the electric wire 4 tending to extend straight, the LA terminal 3 on the connector 2 side is directed upward and rearward, but is held down by the first wall portion 76 and the second wall portion 771, and the LA terminal 3 can be temporarily fixed to the connector 2.

The LA terminal 3 is passed through the rear end portion 75 side of the second wall portion 772 and overlapped with the male terminal 6 on the upper side of the connector 2 with the electric wire 4 facing leftward. Next, the LA terminal 3 connected to the other end of the electric wire 4 is bent toward the right side, and is overlapped on the side surface of the other product 100 and fastened by a bolt. The LA terminal 3 on the other product 100 side is fastened to the front side of the LA terminal 3 on the connector 2 side by a bolt. Therefore, due to a force of the electric wire 4 tending to extend straight, the LA terminal 3 on the connector 2 side is directed upward and rearward, but is pressed by the third wall portion 782 and the second wall portion 772, and the LA terminal 3 can be temporarily fixed to the connector 2. Therefore, after the LA terminals 3 are fastened to the other product 100 by bolts, the temporarily fixed LA terminals 3 only needs to be fastened by bolts without searching for the electric wires 4 to be connected to the male terminals 6 on the upper and lower sides of the two electric wires 4, and thus the fastening workability can be improved.

According to the embodiment described above, the housing 7 includes the pair of second wall portions 771, 772 that respectively stand in the up-down direction from the first wall portion 76 and respectively cover the adjacent LA terminals 3. As a result, even when the electric wires 4 are bent and the LA terminals 3 move in a direction (rearward) away from the rear end portion 75, the LA terminals 3 can be pressed by the second wall portions 771, 772, and temporarily fixed to the housing 7, and workability of bolt fastening of the male terminals 6 and the LA terminals 3 can be improved. Further, the second wall portions 771, 772 serve as partition walls between the adjacent LA terminals 3, 3, and an insulation distance can be increased.

According to the embodiment described above, the lower end of the second wall portion 771 is provided away from the third wall portion 781. Accordingly, the electric wire 4 can be disposed on the male terminal 6 from between a tip end of the second wall portion 771 and the third wall portion 781 without passing through the second wall portion 771 to the rear end portion 75 side, and handleability is improved.

According to the embodiment described above, the upper end of the second wall portion 772 is connected to the third wall portion 782. Accordingly, it is possible to further prevent the LA terminal 3 connected to the electric wire 4 from coming off from the temporary fixation.

According to the embodiment described above, the first wall portion 76 is provided with the notch 761 at the end portion in the leading-out direction of the electric wire 4. Accordingly, as shown in FIG. 4, the electric wire 4 can be inserted into the notch 761, and a bending radius of the electric wire 4 can be increased.

According to the embodiment described above, at the rear end portion 75, the lower side of the first wall portion 76 is provided to further protrude rearward than the upper side of the first wall portion 76, and the notch 761 is provided between the lower side of the first wall portion and the second wall portion 771 at the rear end portion 75. Accordingly, since the positions of the adjacent LA terminals 3 in the front-rear direction are different, even when the LA terminal 3 on the lower side is inserted into the notch 761, insulation of the adjacent LA terminals 3 can be ensured.

According to the embodiment described above, the second wall portion 771 stands on both sides in the up-down direction from the first wall portion 76. Accordingly, it is possible to prevent the LA terminal 3 inserted into the notch 761 from coming off from the temporary fixation.

The present disclosure is not limited to the embodiment described above, and can be appropriately modified, improved, or the like. In addition, materials, shapes, sizes, numbers, arrangement positions and the like of components in the above embodiment are freely selected and are not limited as long as the present disclosure can be implemented.

According to the embodiment described above, the tip end of the second wall portion 771 is provided away from the third wall portion 781, but the present disclosure is not limited thereto. The tip end of the second wall portion 771 may be connected to the third wall portion 781.

According to the embodiment described above, the second wall portion 772 is connected to the third wall portion 782, but the present disclosure is not limited thereto. The second wall portion 772 may be provided away from the third wall portion 782.

It is not essential to provide the notch 761 in the first wall portion 76, and the notch 761 may be omitted.

According to the embodiment described above, at the rear end portion 75, the lower side of the first wall portion 76 further protrudes rearward than the upper side of the first wall portion 76, but the present disclosure is not limited thereto. The rear end portion 75 may be flat.
