  The connector housing 2 has a connector fitting chamber (not shown) opened on the front surface and a pair of wire outlets 3 opened on the rear surface. A mating connector (not shown) is fitted into the connector fitting chamber. A pair of terminals (not shown) to which the terminals (not shown) of the mating connector are connected are arranged at the inner position of the connector fitting chamber. The terminal of the electric wire W is connected to each terminal, respectively. The pair of electric wires W are drawn to the outside from the pair of electric wire outlets 3. A waterproof plug 4 attached to the outer periphery of the electric wire W is press-fitted into each electric wire outlet 3. Each waterproof plug 4 prevents water or the like from entering the connector housing 2 from the wire outlet 3. A cover mounting wall 5 is integrally provided on the rear side of the connector housing 2. The cover mounting wall 5 surrounds the entire periphery of the pair of wire outlets 3. Lock grooves 6 are provided on both sides of the cover mounting wall 5.

  As shown in detail in FIGS. 3 to 5, the connector cover 10 includes a cover main body 11 and a corrugated lid portion 21 connected to a side portion of the cover main body 11 via a hinge portion 20.

  The cover main body 11 includes an electric wire cover main body portion 12 and a corrugated holding portion 13 provided integrally below the electric wire cover main body portion 12. An electric wire housing chamber 14 is provided inside the electric wire cover main body 12. Lock claws 15 that are lock portions are provided on both sides of the wire cover main body 12. The electric wire cover main body 12 is formed with slits 15 a at the upper and lower ends of the lock claws 15. Accordingly, each lock claw 15 is easily bent and shifted in the unlocking direction by the pressing force F shown in FIGS. 6 (a) and 6 (b). The connector cover 10 is attached to the connector housing 2 by the pair of lock claws 15 engaging with the pair of lock grooves 6 of the cover mounting wall 5. In the mounted state of the connector cover 10, the electric wire cover main body 12 is fitted in a state where the front end side thereof partially overlaps the rear end side of the cover mounting wall 5. Thereby, the electric wire accommodating chamber 14 is almost closed.

  In the electric wire accommodating chamber 14, electric wire holding portions 16 are provided to protrude in two places on the left and right. Each electric wire holding part 16 is formed of a pair of electric wire holding arms 16a for holding each electric wire W. Each electric wire W drawn from the electric wire outlet 3 of the connector housing 2 is routed to the electric wire housing chamber 14 while being held by the pair of electric wire holding arms 16a.

  When the electric wire W is pushed into the gap, the pair of electric wire clamping arms 16a bend and deform in a direction to widen the gap, and allow the insertion of the electric wire W. When the electric wire W is pushed in from the narrow position of the gap to the back, the pair of electric wire clamping arms 16a clamps the electric wire W by the bending return force. Therefore, the electric wire holding part 16 holds the electric wire W in a state in which free vibration is suppressed.

  One electric wire holding arm 16a of each electric wire holding portion 16 and each lock claw 15 are connected by a release assisting portion 40, respectively. Each release assisting part 40 is connected on the tip side of each inner wire clamping arm 16a. Each release assisting part 40 is connected on the inner surface side of each lock claw 15. Each unlocking assisting portion 40 is interlocked with the shift of the lock claw 15 and when the lock claw 15 is shifted in the unlocking direction as shown by a virtual line in FIG. 6B, one of the electric wire clamping arms 16a. Are bent and deformed in the direction of releasing the clamping.

  Each release assisting portion 40 is provided with an arc-shaped waterproof stopper holding portion 17 projecting therefrom. The tip of each waterproof plug pressing portion 17 is in contact with the waterproof plug 4. Movement of the waterproof plugs 4 in the wire drawing direction is prevented by the waterproof plug holding portions 17.

  As shown in FIGS. 1 to 3, a corrugated lid portion 21 is connected to an end portion of the corrugated holding portion 13 via a hinge portion 20. Lock claws 22 are provided on both sides of the corrugated holding part 13, and frame-shaped lock arms 23 are provided on both ends of the corrugated cover part 21, respectively. The corrugated lid part 21 is united with the corrugated holding part 13 by the locking claw 22 of the corrugated holding part 13 being engaged with the lock arm 23 of the corrugated lid part 21. A corrugated tube holding chamber 24 is formed inside the corrugated holding part 13 and the corrugated lid part 21. One end side of the corrugated tube holding chamber 24 communicates with the wire housing chamber 14, and the other end side opens to the outside. The inner wall of the corrugated tube holding chamber 24 is formed on the uneven wall 25 corresponding to the outer peripheral uneven shape of the corrugated tube 30. In a state where the corrugated lid portion 21 is combined with the corrugated holding portion 13, one end side of the corrugated tube 30 is engaged with the corrugated holding portion 13 and the concavo-convex wall 25 of the corrugated lid portion 21. Thus, the corrugated tube 30 is fixed to the connector cover 10 at one end side. A pair of electric wires W arranged in the electric wire accommodating chamber 14 is drawn out from the connector cover 10 through the corrugated tube 30.

  As described above, the connector cover 10 includes the electric wire holding portion 16 that holds the electric wires W arranged in the electric wire accommodation chamber 14. Therefore, since the electric wire W is held by the electric wire holding part 16 in the electric wire housing chamber 14, vibration of the electric wire W in the electric wire housing chamber 14 can be prevented.

  In addition to the wire holding portion 16, the connector cover 10 is interlocked with the lock claw 15 that is locked to the connector housing 2 and the shift of the lock claw 15, and the lock claw 15 is moved to the lock release position. And a release assisting part 40 for displacing the electric wire holding part 16 to the holding release position. Therefore, when the pair of lock claws 15 are moved to the unlocking position so as to remove the connector cover 10 from the connector housing 2, the electric wire holding parts 16 are displaced to the holding release positions by the respective release assisting parts 40. Since the electric wire W also comes off at the same time, it is not necessary to perform the work of removing the electric wire W separately. From the above, the vibration of the electric wire W in the electric wire housing chamber 14 can be prevented, and the disassembly workability of the connector cover 10 is good.

  The electric wire holding part 16 is formed by a pair of electric wire holding arms 16a for holding the electric wire W, and the release auxiliary part 40 has a structure for connecting between the lock claw 15 and one electric wire holding arm 16a. Accordingly, the release assisting part 40 can be configured with a simple structure.

  The release assisting part 40 is provided with a waterproof stopper holding part 17. Therefore, even if the pulling force of the electric wire W acts on the waterproof plug 4, it is possible to prevent the waterproof plug 4 from moving from the electric wire outlet 3 due to movement in the electric wire drawing direction.
