That is, when the first general-purpose connector 10 is placed on the base member 100, the first general-purpose connector 10 does not float from the base member 100, and the first general-purpose connector 10 is positioned at a predetermined position on the base member 100. will be placed.

Here, the variable through hole 124BH may or may not penetrate the base member 100 as described above. Also, here, the first rod 124 and the second rod 126 are described in a bolt shape (hexagon socket bolt shape) having a threaded portion, but the first through hole 14 and the second through hole 16 and It is not necessary to screw into the variable through hole 124BH, and the diameter of the screw portion of the first rod 124 and the second rod 126 is smaller than the diameter of the first through hole 14 and the second through hole 16, and the first rod The diameter of the bolt head portion of 124 (the head portion provided with the hexagonal hole) is smaller than the diameter of the variable through hole 124BH.

Furthermore, the L-shaped angle 10L is attached to the first general-purpose connector 10 by a first rod 124B and a second rod 126B that pass through the first through-hole 14 and the second through-hole 16 of the first general-purpose connector 10. there is The L-shaped angle 10L has a horizontal portion 10LH and a vertical portion 10LV. The horizontal portion 10LH has a through hole 10L14 corresponding to the position of the first through hole 14 of the first general-purpose connector 10 and a second through hole 10L14 of the first general-purpose connector 10. A through hole 10L16 corresponding to the position of the hole 16 is provided. More specifically, as shown by arrow D in FIG. 3, the first rod 124B passes through the first through hole 14 of the first general-purpose connector 10 from the bottom (the side of the base member 100) to the top to form an L-shaped angle. A nut 124N is screwed through the through hole 10L14 of 10L, and the second rod 126B penetrates the second through hole 16 of the first general-purpose connector 10 from the bottom (base member 100 side) to the top to form an L-shaped angle. A nut 126N is screwed through a through hole 10L16 of 10L. A force F shown in FIG. 7(A) acts on the vertical portion 10LV of the L-shaped angle 10L during an emergency stop, which will be described later.

Then, the rod-shaped object (first rod 124B) inserted and fitted in the first through-hole 14 is fitted into the variable through-hole 124BH in the state shown in FIG. 3 or FIG. 10 are positioned on the base member 100 . As described above, the end portion of the base member 100 on the side of the first general-purpose connector 10 and the flat plate 121 forming the holding portion 120 are in the first state (Fig. 6) and a second state (state shown in FIG. 5) in which the base member 100 and the holding portion are substantially flush with each other, and are connected by a hinge 100T. Therefore, the bolt head portion of the rod-shaped object (first rod 124B) inserted and fitted in the first through hole 14 is in the state shown in FIG. 3 or FIG. The first general-purpose connector 10 is positioned on the base member 100 by fitting it into the variable through-hole 124BH in the state of being rotated outwardly, and the first general-purpose connector 10 is held so as not to move in the sliding direction. The rod-shaped object (first rod 124B) inserted and fitted in the first through-hole 14 is variable to the state shown in FIG. Since the first general-purpose connector 10 cannot be fitted into the through hole 124BH, the first general-purpose connector 10 is not positioned on the base member 100 and is held so as to be movable in the sliding direction.

In this way, in the state shown in FIG. 6 where the first general-purpose connector 10 and the second general-purpose connector 20 are connected (the state in which the hinge 100T is rotated to the arrow R(4) side), FIG. A) When a force in the direction of arrow F is applied to the vertical portion 10LV of the L-shaped angle 10L, the first rod 124B cannot be fitted into the variable through-hole 124BH, so the first general-purpose connector 10 slides in the sliding direction ( arrow X direction), and a stopper 220ST provided in the slide groove 220S prevents the sliding surface 200S of the holding member 200 from sliding in the slide groove 220S, thereby causing the second general-purpose connector 20 to slide. Since the force F acting on the first general-purpose connector 10 prevents the second general-purpose connector 20 from moving in the direction (direction of arrow X), the second general-purpose connector 20 is prevented from moving in the direction (direction of arrow X). (because it cannot be done), the first general-purpose connector 10 is disconnected from the second general-purpose connector 20, and the connection between the first general-purpose connector 10 and the second general-purpose connector 20 is cut off. This force F is applied in conjunction with an emergency stop function provided in the electric transport vehicle (for example, when an emergency stop lever (not shown) is operated, the force in the direction of arrow F is applied to the vertical portion of the L-shaped angle 10L). 10LV), and when the emergency stop function is activated, the general-purpose connector provided between the battery and the in-vehicle electric motor is forcibly disconnected, and the power supply to the in-vehicle electric motor can be cut off in an emergency. become.

A flat plate 130 having a stopper 130ST on a protruding portion 130S is fixed with a bolt or the like. In order for the stopper 130ST to function as described above, the protrusion 130S protrudes from the end face of the base member 100 on the side of the second general-purpose connector 20 and extends in the width direction of the base member 100 (the direction perpendicular to the arrow XY direction, which is the sliding direction). The flat plate 130 is joined to the base member 100 by a fastening member such as a bolt so that the stopper 130ST of the protrusion 130S protrudes from there.
In the connector connection jig 1000 having such a structure, the grip 242 serves as the force point, the fulcrum bolt 260 of the standing member 220 serves as the fulcrum, and the connecting side working rod 224 screwed into the holding member 200 or the separating side working rod 224 is screwed into the holding member 200 .
