[0023] The rear end of the oil-immersed portion 72, the central restricting wall 752, the left wall portion 761, and the upper restricting wall 751 form a nut accommodating groove 771 that accommodates a nut 5 to be connected to the left-side male terminal 6. This nut accommodating groove 771 extends in the left-right direction, and is provided with an insertion opening 781 on the right side for inserting the nut 5. That is, the right side of the nut accommodating groove 771 in the left-right direction corresponds to the "one side in the intersecting direction" of the present invention.

[0024] Furthermore, a nut accommodating groove 772 that accommodates a nut 5 to be connected to the right-side male terminal 6 is provided by the rear end of the oil-immersed portion 72, the central restricting wall 752, the right-side wall portion 762, and the lower restricting wall 753. This nut accommodating groove 772 extends in the left-right direction, and is provided on the left side with an insertion opening 782 for inserting the nut 5. That is, the left side of the nut accommodating groove 772 in the left-right direction corresponds to the "one side in the intersecting direction" of the present invention.

[0025] As shown in FIG. 1 , the rear end of the first portion 62 and the second connecting portion 63 of the male terminal 6 protrude from the accommodating hole 74 to the outside of the housing 7. The second connecting portion 63 is bent from the rear end of the first portion 62 toward the insertion openings 781 and 782. The second connecting portion 63 is disposed with a gap in the front-to-rear direction from the bottom surfaces of the nut accommodating grooves 771 and 772. When the nut 5 is accommodated between the second connecting portion 63 and the bottom surfaces of the nut accommodating grooves 771 and 772, the nut 5 is sandwiched between the second connecting portion 63 and the housing 7. The bending protrusion 65 protrudes from the tip of the second connecting portion 63 toward the insertion openings 781 and 782, and the tip is bent forward to engage the flange portion 52 of the nut 5.

[0026] 2, the LA terminal 3 has a terminal connection portion 31 connected to the male terminal 6 and a wire connection portion 32 connected to the wire 4, which are provided in series in the left-right direction. The terminal connection portion 31 is formed in a plate shape and has a bolt through-hole 33 through which a bolt 9 passing therethrough in the front-rear direction is inserted.

[0027] Next, the assembly procedure for the connector-equipped wire harness 1 having the above-described configuration will be described. The male terminal 6 is inserted into the housing 7. Next, as shown in FIG. 4, the nut 5 is inserted into the nut accommodating grooves 771, 772 through the insertion openings 781, 782. At this time, the nut 5 is inserted between the bottom surfaces of the nut accommodating grooves 771, 772 and the second connecting portions 63 of the male terminals 6 with the flange portions 52 of the nut 5 facing rearward. Note that before the nut 5 is inserted, the bending protrusions 65 are not bent and are straight in the left-right direction.

[0028] After inserting the nut 5 until the flange portion 52 abuts against the wall portions 761, 762, the bending protrusion 65 is bent forward as shown in Figures 5 and 6. This locks the bending protrusion 65 and the nut 5, preventing the nut 5 from falling out of the insertion openings 781, 782.

[0029] Next, the LA terminal 3 and the male terminal 6 are connected. First, the terminal connection portion 31 of the LA terminal 3 is placed over the second connection portion 63 of the male terminal 6. At this time, the LA terminal 3 to be connected to the right-side male terminal 6 is positioned with the terminal connection portion 31 facing right and the electric wire connection portion 32 facing left. That is, the electric wire 4 is drawn out to the left from the LA terminal 3 to be connected to the right-side male terminal 6. The LA terminal 3 to be connected to the left-side male terminal 6 is positioned with the terminal connection portion 31 facing left and the electric wire connection portion 32 facing right. That is, the electric wire 4 is drawn out to the right from the LA terminal 3 to be connected to the left-side male terminal 6.

[0030] According to the above-described embodiment, after the nut 5 is inserted into the nut accommodating grooves 771, 772, the bending protrusions 65 can be bent to lock the nut 5. Therefore, there is no need to press the nut 5 into the nut accommodating grooves 771, 772, making it easy to insert the nut 5 and preventing the nut 5 from falling off even before the bolt is tightened. Furthermore, by bending the bending protrusions 65, the nut 5 can be tightly locked and therefore the holding force of the nut 5 is improved.

[0031] According to the embodiment described above, the bending protrusion 65 is engaged with the rectangular flange portion 52. This allows the bending protrusion 65 to be engaged with the flat end surface of the flange portion 52, further preventing the nut 5 from falling off.
