A protector 50 for protecting the seal ring 28 externally fitted to the connector main body 26 is attached to the device connector 20 before being attached to the inverter device 10. As shown in FIGS. 5 to 7, the protector 50 includes a pair of substantially semi-circular portions 51, 51 (corresponding to substantially semi-circular portions of the present invention) which can be attached to the connector body 26, and these substantially semi-circular portions. It comprises a hinge portion 52 connecting the 51 and 51, and a lock means 53 for holding the substantially semicircular arc portions 51 and 51 in a mounted state with respect to the connector body 26. The substantially semicircular arc portion 51 has a substantially U-shape in which one end side is thicker than the other end side, and the pair of substantially semicircular arc portions 51, 51 are combined so as to form a substantially circular shape. The connector body 26 can be attached so as to be almost exactly along the outer periphery thereof. The thin ends of the pair of substantially semicircular arc portions 51, 51 are connected to each other via a hinge 52, and the expanding displacement can be performed using the hinge 52 as a fulcrum. Further, a locking means 53 is provided on the thick end side of the pair of substantially semicircular arc portions 51, 51. The locking means 53 includes a deformable lock piece 54 provided on one substantially semicircular arc portion 51 side and a receiving concave portion 55 provided on the other substantially semicircular arc portion 51 side (corresponding to a receiving portion of the present invention).

Is held in a mounted state. The receiving recess 55 is set to have a slightly larger dimension than the locking projection 54A. Further, when the locking projection 54A is locked in the receiving recess 55, the gap is set to have a small gap 56 between the opposing surfaces of the ends of the pair of substantially semicircular arcs 51, 51 (FIG. 5 and 7). Further, the surface of the lock piece 54 facing the gap 56 is formed in a concave shape over a wider width than the gap 56, and is a thin portion 54B.
[0025]
Next, the operation of the present embodiment will be described.
When the manufacture of the device connector 20 is completed, first, as shown in FIG. 6, the pair of substantially semicircular arc portions 51, 51 of the protector 50 are expanded with the hinge portion 52 as a fulcrum, and then the outer periphery of the connector body 26 is removed. By closing the fitted seal ring 28 so as to cover it, the protector 50 is attached to the connector body 26. Then, the protector 50 is held in the mounted state with respect to the connector main body 26 by locking the locking convex portion 54 </ b> A of the lock piece 54 to the receiving concave portion 55. At this time, the mounting direction of the protector 50 with respect to the connector main body 26 is such that the locking means 53 is located on the rear side (the right side in FIG. 8) of the mounting direction of the device connector 20 with respect to the inverter device 10 as shown in FIG. It should be positioned so as to be positioned on the side of the connector body 26 and not interfere with the mounting portion 29. As a result, the seal ring 28 is protected by the protector 50, and is prevented from being damaged during packing or during transportation.
[0026]
When attaching the device connector 20 to which the protective device 50 is attached to the inverter device 10 as described above, first, the connector main body 26 is coaxially corresponding to the mounting hole 12 and the gap 56 of the protective device 50 is formed. The connector main body 26 is caused to enter the mounting hole 12 so as to coaxially correspond to the locking release rib 17 of the shield case 11. Then, the unlocking rib 17 formed on the shield case 11 enters into the gap 56 of the protector 50, and eventually comes into contact with the lock piece 54. When the connector main body 26 is further pushed into the mounting hole 12, as shown in FIG. 9, the lock piece 54 is bent and deformed rightward in the figure with the end of the thin portion 54B as a fulcrum by the locking release rib 17. At this time, since the protector 50 is in contact with the front surface of the mounting portion 29, even if the lock piece 54 is pushed from the front by the locking release rib 17, the protector 50 is prevented from escaping backward. Is done. As a result, the engagement of the engaging projection 54A with the receiving recess 55 is reliably released, and the pair of substantially semicircular arc portions 51, 51 can be expanded and displaced with the hinge portion 52 as a fulcrum.
[0027]
In such a state, the protector 50 detaches from the connector main body 26 while expanding and displacing the substantially semicircular arc portions 51, 51 with its own weight (see FIG. 10), and falls automatically. Alternatively, when the connector 50 is not dropped and is hooked on the connector main body 26, the protector 50 can be dropped from the connector main body 26 by simply touching the worker. After that, the bolt penetrating portion 30 is made to coaxially correspond to the female screw hole 13 of the shield case 11, and the connector main body 26 is advanced into the mounting hole 12 until the mounting portion 29 contacts the outer surface of the shield case 11. Thereby, the connection part 22 at the front end of the wire side terminal 21 is oriented horizontally and overlaps the upper surface of the device side terminal 14, and the bolt holes 23 of the wire side terminal 21 correspond to the bolt holes 15 of the device side terminal 14. .
[0028]
Thereafter, the mounting portion 29 and the connector main body 26 are fixed to the shield case 11 by screwing the bolt 45 inserted from behind into the bolt penetration portion 30 into the female screw hole 13.
[0029]
After all the connector bodies 26 are fixed to the shield case 11 in this manner, the bolts 46 are passed through the bolt holes 15 and 23 of the device-side terminal 14 and the wire-side terminal 21 in the shield case 11, and The nut 47 is screwed, and the two terminals 14 and 21 are connected in a conductive manner. Also, before and after the connection of the terminals 14 and 21, the shield shell 40 is attached to the shield case 11. Thus, the attachment of the device connector 20 to the inverter device 10 is completed.
[0030]
As described above, in the present embodiment, since the seal ring 28 externally fitted to the connector main body 26 of the device connector 20 is covered by the protector 50, the device connector 20 is packed and transported, or the inverter device 10 is mounted. The seal ring 28 is prevented from being damaged at the time of the mounting operation on the seal ring 28. Therefore, there is an excellent effect that the waterproofness of the assembled device can be ensured. In addition, when the device connector 20 is attached to the inverter device 10, the lock state of the protector 50 of the present embodiment is released by the contact with the inverter device 10 and automatically released from the connector main body 26. With this configuration, the step of detaching the protective device 50 can be omitted, and the productivity can be increased. Further, since the protector 50 can be used repeatedly, it is also good for the environment. Further, since the protective device 50 is configured to be separated from the connector main body 26 by the pair of substantially semicircular arc portions 51, 51 being expanded and displaced, the protective device 50 is separated along the circumferential direction and the axial direction of the connector main body 26. An excellent effect is obtained in that the seal ring 28 is less likely to be scratched as compared with the configuration, and that the seal ring 28 is not easily damaged.
