9A and 9B are views for explaining the attachment operation of the connector cover, FIG. 9A is a cross-sectional view taken along the line AA in FIG. 3A, and FIG. 9B is a view taken along the line BB in FIG. 3A. It is a cross-sectional view.
First, the first cover 11 of the connector cover 10 is attached to the connector 40. Specifically, as shown in FIG. 7A, the first cover 11 is brought close to the upper portion at the rear end of the connector 40, and the CPA 45 of the connector 40 is placed in the locking groove 22 of the locking portion 21 of the first cover 11. The formed locking piece 75 is inserted and engaged. In this way, the electric wire regulation wall 26 of the first cover 11 is arranged at a position facing the end surface of the electric wire 41 of the connector 40 on the pull-out side, and the electric wire 41 drawn from the connector 40 is the electric wire accommodating recess 27 of the electric wire regulation wall 26. Get inside. Here, since the electric wire regulation wall 26 protrudes from the lead-in position H of the electric wire 41, the electric wire 41 can be smoothly inserted into the electric wire accommodating recess 27 of the electric wire regulation wall 26 and accommodated. In particular, in the electric wire regulation wall 26, since both side portions of the electric wire accommodating recess 27 are the extending portions 26a extending toward the second cover 12 side, the extending portions 26a do not protrude the electric wires 41 to the outside. It can be surely inserted into the electric wire accommodating recess 27 between the two.

Next, the corrugated tube 80 is attached to the first cover 11 of the connector cover 10. Specifically, the corrugated tube 80 is brought close to the connector 40 to which the first cover 11 of the connector cover 10 is mounted, and the end portion of the corrugated tube 80 is brought into contact with the electric wire regulation wall 26. In this way, the corrugated tube 80 is axially positioned with respect to the first cover 11. From this state, the corrugated tube 80 is inserted into the holding groove portion 23 of the first cover 11. Then, as shown in FIG. 7B, the locking ridge 24 of the holding groove portion 23 enters the valley portion 82 of the corrugated tube 80, and the end portion of the corrugated tube 80 is locked to the holding groove portion 23.

After that, as shown in FIGS. 9 (a) and 9 (b), the second cover 12 is rotated with respect to the first cover 11 around the connection portion by the hinge portion 13. Then, the second cover 12 is abutted against the first cover 11 attached to the connector 40 and to which the corrugated tube 80 is locked.

Then, the locking piece 75 formed in the CPA 45 of the connector 40 is inserted into the locking groove 32 of the locking portion 31 of the second cover 12 and engaged with the locking groove 32. Then, the electric wire regulation wall 36 of the second cover 12 comes into contact with the electric wire regulation wall 26 of the first cover 11. As a result, a hole is formed by the wire accommodating recesses 27 and 37 of the wire regulation walls 26 and 36 of the first cover 11 and the second cover 12, and the wire 41 is held in a state of being inserted into the hole. Further, the corrugated tube 80 enters the holding groove 33 of the second cover 12. As a result, the locking ridge 34 of the holding groove 33 enters the valley 82 of the corrugated tube 80, and the end of the corrugated tube 80 is locked to the holding grooves 23 and 33 of the first cover 11 and the second cover 12.

By the way, as shown in FIG. 10, when the end portion of the corrugated tube 80 is brought into contact with the electric wire regulation wall 26 of the first cover 11 for positioning, the end portion of the corrugated tube 80 gets over the electric wire regulation wall 26 and is connected. It is conceivable that it is arranged on the 40 side.

However, since the electric wire regulation wall 26 has a thickness T larger than the pitch Pm of the mountain portion 81 of the corrugated tube 80, the electric wire regulation wall 26 reaches the valley portion 82 between the mountain portions 81 of the corrugated tube 80. Does not get in. Therefore, in this case, the corrugated tube 80 is not accommodated in the holding groove portion 23 and is in a raised state, and when the second cover 12 is rotated with respect to the first cover 11 in this state, the raised corrugated tube 80 is second. The cover 12 hits. Therefore, the second cover 12 cannot be rotated and abutted against the first cover 11, and the operator can easily confirm the misalignment of the corrugated tube 80.

Therefore, it is possible to suppress the biting of the electric wire 41 when the first cover 11 and the second cover 12 are butted against each other. Further, the facing positions of the electric wire regulation walls 26 and 36 are biased toward the second cover 12 side with respect to the lead-in position H of the electric wire 41 from the connector 40. Therefore, the electric wire 41 drawn from the connector 40 can be easily and surely accommodated in the electric wire accommodating recess 27 of the electric wire regulation wall 26 of the first cover 11. Moreover, the electric wire regulation wall 26 for arranging the electric wire 41 in the center in the width direction is a positioning wall portion for positioning the corrugated tube 80 in the axial direction by bringing the end portions of the corrugated tube 80 into contact with each other. Therefore, as compared with the case where the wall portion and the protrusion for suppressing the protrusion of the electric wire 41 are separately provided, the bulkiness of the total length can be suppressed and the size can be reduced.

Further, the abutting position between the first cover 11 and the second cover 12 is set to an intermediate position in the radial direction of the corrugated tube 80 to be held. Therefore, the holding range of the corrugated tube 80 by the first cover 11 and the second cover 12 along the circumferential direction can be made uniform, and the corrugated tube 80 can be held in a well-balanced manner.

Moreover, since the extending portions 26a extending toward the second cover 12 side are provided on both side portions of the electric wire accommodating recess 27 of the electric wire regulating wall 26 provided on the first cover 11, the electric wire accommodating recess 27 can be accommodated. The work of pulling in the electric wire 41 can be easily performed.

Further, the electric wire regulation wall 26 for positioning the corrugated tube 80 has a thickness T larger than the pitch Pm of the mountain portion 81 of the corrugated tube 80. Therefore, even if the end portion of the corrugated tube 80 is misplaced over the electric wire regulation wall 26, the electric wire regulation wall 26 can enter the valley portion 82 between the mountain portions 81 of the corrugated tube 80. Can be suppressed. That is, the corrugated tube 80 misplaced on the first cover 11 is in a raised state, the second cover 12 cannot be abutted, and the misplaced corrugated tube 80 can be easily confirmed.
