Here, locking claws 61 having tapered surfaces are provided on the upper and lower surfaces of the drawn-out portion of the harness W formed on the rear surface side of the housing 6. The cover 7 has a U-shaped cross section, and locking windows 71 are formed on the free ends of the upper and lower surface portions 7a and 7b for engaging the locking claws 61. Then, the cover 7 is inserted from the rear side of the housing 6 toward the front side and sandwiched from above and below, and the locking window 71 is locked by the locking claw 61 at the position where the tip of the cover 7 contacts the stopper 63. To engage
The cover 7 is attached to the housing 6.

As another type, as shown in FIG. 7, a plurality of tongue-shaped locking portions 81 are formed at the tip of the cover 8 and locking windows 82 are formed in these locking portions 81. Some of them are formed so that these locking windows 82 are engaged with the locking claws 61 of the housing 6.

[0004]

However, for example, taking the one shown in FIG. 6 as an example, the engagement between the locking claw 61 of the housing 6 and the locking window 71 of the housing 7 is shown in FIG. As described above, since the cover 7 is engaged only in the front-rear direction, which is the attaching / detaching direction, there is the following problem.

That is, when the upper and lower surfaces 7a and 7b of the cover 7 are warped outward as shown in FIG. 9, the engagement of the engagement window 71 with the engagement claw 61 is released. Further, as shown in FIG. 10, the wire harness W is covered with a cover 7
Similarly, when it is lifted toward the outside, the engagement of the engagement window 71 with the engagement claw 61 is released. Therefore,
A force must be applied to the upper and lower surfaces 7a and 7b of the cover 7 in the directions of the arrows in FIG. 9, that is, in the direction of holding the housing 7, and the material of the cover 7 is not limited to a hard material. Will end up.

The structure shown in FIG. 7 has the same problem for the same reason.

Therefore, an object of the present invention is not to limit the material of the cover, and to prevent the cover from being disengaged from the housing even if a force is applied to the cover in the vertical direction. The purpose of the present invention is to provide a mounting structure for a housing cover.

[0008]

According to the present invention, in a structure in which a cover, which is detachable in a first direction with respect to a housing accommodating a harness drawer portion, is attached to the housing, the cover is attached to the housing in the first direction. First and second housing locking portions are provided on both outer surfaces in the second direction orthogonal to each other, and the inner surface of the cover is engaged with the first and second housing locking portions, respectively. First and second cover locking portions are provided, and the first housing locking portion and the first cover locking portion are the first and second cover locking portions.
And in a third direction orthogonal to the second direction, relative movement is possible, and when in a first relative position in the third direction, relative movement is possible in the first direction, but second movement is possible. The second housing locking portion and the second cover locking portion are configured to be engaged with each other in the first direction when in the relative position, and the second housing locking portion and the second cover locking portion are configured to engage with each other. Part and the first cover locking part are relatively movable in the third direction when in the first relative position, but in the third direction when in the second relative position. It is possible to obtain an attachment structure for a harness housing cover, which is characterized in that it is configured to engage with.

Further, according to the present invention, the first housing locking portion and the first cover locking portion are arranged at predetermined intervals in the third direction. It is possible to obtain a mounting structure for the harness housing cover.

[0010]

According to the harness housing cover mounting structure of the present invention, the first cover locking portion is directed to the first housing locking portion, and the cover and the housing are aligned in the third direction. When relatively moved, the first housing locking portion and the first cover locking portion are engaged with each other. At this time, since the first housing locking portion and the first cover locking portion are engaged with each other so as to be movable only in the third direction, the cover is locked in the second direction. The mutual engagement is not released even when a force is applied to the. Then, when the cover is moved to one side in the third direction, the second cover locking portion engages with the second housing locking portion, and the cover moves in the third direction. Is locked.

Further, according to the present invention, the first housing locking portion and the first cover locking portion are respectively provided in the third housing.
If it is formed at a predetermined interval in the direction of, the mutual engagement of the first housing locking part and the first cover locking part can be started through the interval, and thus the third housing locking part can be started. The movement in the direction of can be reduced.

[0012]

Embodiments of the present invention will now be described with reference to the drawings. 1 is a perspective view showing a first embodiment of the present invention, FIG. 2 is an enlarged side sectional view around an engaging portion, FIG. 3 is an enlarged plan view around an engaging portion, and FIG. 4 is an engaging portion. It is the enlarged view seen from the back side of the circumference.

As shown in FIG. 1, from the rear side of the housing 1 which houses the harness pull-out portion (not shown),
The wire harness is pulled out in the direction C. On both surfaces of the housing 1 in a second direction orthogonal to the first direction C, that is, on the upper and lower surfaces of the housing 1 in the vicinity of the rear end portions thereof, the first housing locking portion 11 has the first and second directions. A plurality of them are provided at a predetermined interval in the third direction orthogonal to, that is, the longitudinal direction of the housing 1. A stopper 12 extending in the longitudinal direction is provided in front of these first housing locking portions 11. Further, a second housing locking portion including a taper locking portion 13 and a stopper portion 15 is provided on one end side in the longitudinal direction, that is, on the right end portion in FIG. The taper locking portion 13 is formed with a slope that rises toward the end in the longitudinal direction. The taper locking portion 13 and the stopper portion 15 are separated from each other in the longitudinal direction to form a gap portion so that the second cover locking portion 33 can be engaged therebetween.

The cover 3 has a U-shaped side cross section and has an upper surface portion 3a and a lower surface portion 3b. Inside the upper and lower surfaces 3a and 3b, the first housing locking portion 1
A first cover locking portion 31 that engages 1 is provided. The second cover locking portion 33 is located on the rightmost side of the first cover locking portion 33.
The housing locking portion 11 extends forward.

The first housing locking portion 11 and the first cover locking portion 31 are engaged so as to be movable only in the longitudinal direction, as shown in FIGS. Therefore, preferably the first
As best seen from FIG. 2, the housing locking portion 11 of the housing includes a vertical portion that extends vertically from the upper and lower surfaces of the housing 1, and a horizontal portion 11a that extends from the tip of the housing 1 toward the front side in the horizontal direction. On the other hand, the first cover locking portion 31 is formed with a space 31a having a specific shape for fitting and housing the first housing locking portion 11 so as to extend in the longitudinal direction of the cover 3. Although FIG. 2 shows only the upper surface portion 3a side of the cover 3, the lower surface portion 3b also appears symmetrically.

To attach the cover 3 to the housing 1,
As shown in FIG. 1, first, the cover 3 is inserted into the housing 1 (in the direction of arrow A) until the first cover locking portion 31 contacts the stopper 12 between the first housing locking portions 11. After this, the cover 3 is moved in the longitudinal direction (arrow B direction).
2 to obtain the engaged state as shown in FIG. For this reason, it is preferable that the insertion side end portions of the first housing locking portion 11 and the first cover locking portion 31 have the positions shown in FIGS.
As is best understood from the above, the taper portion is formed and is configured to guide each other so that the locked state can be smoothly obtained.

When the cover 3 is slid in the direction of arrow B in FIG. 1, the second cover locking portion 33 rides on the tapered surface of the taper locking portion 13 of the second housing locking portion to taper. The cover 3 is dropped into the gap between the locking portion 13 and the stopper portion 15, and the attachment of the cover 3 to the housing 1 is completed. In this state, since the second cover locking portion 33 is located between the taper locking portion 13 of the housing 1 and the stopper portion 15, the cover 3 can no longer slide in the longitudinal direction. Further, since the first housing locking portion 11 and the first cover locking portion 31 are in an engagement state that cannot be disengaged in the vertical direction as shown in FIG. 2, the cover 3 is separated from the housing 1. Even if a warp occurs in the direction, the first cover locking portion 31 does not separate from the first housing locking portion 11. In addition, even if a force is applied to the wire harness W in the pull-out direction (direction C) after the cover 3 as shown in FIG. 1 is attached, the first housing locking portion 11 and the first cover locking portion 31 are not separated from each other. Due to the engagement, the cover 3 does not separate in the direction opposite to the A direction.

Since the first housing locking portion 11 and the first cover locking portion 31 are engaged with each other, the material of the cover 3 can be made of a highly flexible material. In view of this point, the cover 3 is made of a highly flexible material, and a minus screwdriver or the like is inserted between the housing 1 and the cover 3 to pry the cover 3 in a direction to lift the second cover locking portion. The engagement between 33 and the second housing locking portion can be released. According to this, it becomes possible to easily remove the cover 3 by sliding the cover 3 in the direction opposite to the B direction.

In this case, preferably, as shown in FIG. 1, a slit 38 is formed in the cover 3 to facilitate the bending of the cover 3. This makes it easier to release the lock of the second cover locking portion 33. It should be understood that if a release lever or the like that functions as a minus driver is provided on the cover 3 or the housing 1, the lock can be released by operating the release lever.

Also preferably, the cover 3 is attached to the housing 1.
A positioning stopper 12 for positioning the first cover locking portion 31 in the opening of the first housing locking portion 11 at the time of mounting in the front direction is provided on the housing side. Instead of this, as shown in FIG. 5, a positioning stopper 35 in the front-rear direction may be provided on the cover 3 side. Note that FIG.
In FIG. 1, the wire harness pulled out from the back side of the housing 1 is omitted for simplification of illustration.

Further, preferably, the first housing locking portion 11 and the first cover locking portion 31 engaging with the first housing locking portion 11 are intermittently provided at a predetermined interval. According to this,
The sliding amount of the cover 3 in the longitudinal direction of the housing 1 can be shortened. Therefore, if the slide amount may be long, although not shown, it goes without saying that the locking portions 11 and 31 may be integrally continuous in the longitudinal direction.
Further, the first housing locking portion 11 may be continuously formed, and the first cover locking portion 31 may be intermittently provided at a predetermined interval. On the contrary, the first cover locking portion 31 may be continuously formed and the first housing locking portion 11 may be intermittently provided at a predetermined interval.

[0022]

As described above, according to the present invention,
Since the first cover locking portion is engaged with the first housing locking portion in a fitted state, the mutual engagement force is strengthened,
Even if the cover material is a soft material, the engaged state can be maintained reliably, and mutual engagement will not be released even if the cover warps or the wire harness is distorted. Further, according to the present invention, since the cover is attached to the housing by sliding,
It becomes easy to attach and detach.
