The cross section of the first rib 43L is, for example, triangular. Since the plurality of first ribs 43L bite into the electric wire 12, the electric wire 12 is suppressed from moving in the front-rear direction with respect to the first cover member 16L and the second cover member 16U.

In the following description, it is assumed that the surface 21 of the rear wall portion 18 is the upper end surface of the rear wall portion 18 (hereinafter referred to as the upper end surface 21). The height of the upper end surface 21 of the rear wall portion 18 matches the height of the upper end surface of the side wall portion 19 . A pair of first protrusions 23L projecting upward from both left and right sides of the first groove 22L when viewed in the front-rear direction are formed on the upper end surface 21 for each first groove 22L. The side surface on the first groove 22L side of each first protrusion 23L continues to the inner surface of the first groove 22L, and the side surface on the first groove 22L side and the inner surface of the first groove 22L are flush with each other. A rib is also formed on the side surface of the first protrusion 23L on the side of the first groove 22L so as to extend the first rib 43L formed in the first groove 22L.

While the first cover member 16L is pushed up, the second cover member 16U is pushed down so that the flanges 15 of the connector 11 are inserted into the vertical grooves 25 and the horizontal grooves 26 of the second cover member 16U from below.

At this time, the lock arm 32 of the first cover member 16L is engaged with the engagement protrusion 33 of the second cover member 16U, and the lock arm 32 of the second cover member 16U is engaged with the engagement protrusion 33 of the first cover member 16L. The first cover member 16L and the second cover member 16U are engaged by mating.
Furthermore, the engaged

portions

42U and 42L formed on the side wall portions 19 of the first cover member 16L and the second cover member 16U are engaged with the engaging

projections

40U and 40L of the housing 14 of the connector 11, respectively. The wire cover 13 and the connector 11 are engaged with each other.

As shown in FIG. 6, when the wire cover 13 is attached to the connector 11, the first cover member 16L and the second cover member 16U are arranged point-symmetrically when viewed from the rear side. A dotted line 34 in FIG. 6 indicates a position where the upper end face 21 of the first cover member 16L and the upper end face 21 of the second cover member 16U abut. In other words, the dotted line 34 indicates the position of the joint between the first cover member 16L and the second cover member 16U.

(5) Effect of Embodiment The effect of the embodiment will be described in comparison with a comparative example. A comparative example shown in FIG. 11 shows an example of a conventional common wire cover. As shown in FIG. 11, the wire cover 501 according to the comparative example is divided into a first cover member 502 arranged on one side in the radial direction of the wire 12 and a second cover member 503 arranged on the other side. The structure is such that the electric wire 12 can come into contact with the joint between the two

cover members

502 and 503 . In the wire cover 501 having such a structure, when the wire 12 vibrates, a load is applied from the wire 12 to the joint between the two

cover members

Therefore, it becomes difficult to apply a load from the electric wire 12 to the joint between the first cover member 16L and the second cover member 16U, and the electric wire cover 13 becomes difficult to open. Therefore, according to the wire cover 13, there is a problem in suppressing the vibration of the wire 12 by the wire cover 13 (when the wire 12 vibrates, a load is applied from the wire 12 to the joint between the first cover member 16L and the second cover member 16U). Therefore, the problem that the wire cover 13 becomes easy to open) can be improved.

According to the wire cover 13, the first cover member 16L is provided with a first groove 22L and a pair of first projections 23L for each wire 12, and the second cover member 16U is provided with a second groove 22U for each wire 12. , and a pair of second protrusions 23U are provided, two cover members 16 are sufficient for the plurality of electric wires 12 . Therefore, the number of parts can be reduced compared to the case where each electric wire 12 is provided with the first cover member 16L and the second cover member 16U.

According to the wire cover 13, since the first cover member 16L and the second cover member 16U have the same shape, the types of parts can be reduced compared to the case where the first cover member 16L and the second cover member 16U have different shapes. . Therefore, the cost of the wire cover 13 (development cost, manufacturing cost, management cost, etc.) can be reduced.

According to the wire cover 13, the first rib 43L is formed on the inner surface of the first groove 22L, and the second rib 43U is formed on the inner surface of the second groove 22U. By biting into the wire cover 12 , it is possible to suppress the wire 12 from moving forward and backward with respect to the wire cover 13 .

According to the connector structure 1, the problem of suppressing the vibration of the electric wire 12 by the electric wire cover 13 can be improved.

According to the connector structure 1, since the first engaging portion (the engaged portion 42L and the engaging projection 40L) and the second engaging portion (the engaged portion 42U and the engaging projection 40U) are provided, the first cover It becomes difficult for the member 16L and the second cover member 16U to come off from the connector 11 .

<Embodiment 2>

When the first cover member 216L is also viewed from the front-rear direction, the first protrusions 23L protrude from both sides of the first groove 22L, but these two first protrusions 23L are displaced from each other in the front-rear direction. Therefore, even if only one electric wire 12 is led out, the first convex portion 23L of the first cover member 216L and the second convex portion 23U of the second cover member 216U do not abut each other.
Embodiment 2 is substantially the same as Embodiment 1 in other respects.

<Embodiment 3>
Embodiment 3 will be described with reference to FIG. The wire cover 313 according to Embodiment 3 includes a first cover member 316L and a second cover 316U.
