Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a member mounting structure for mounting a first member on a member to be mounted and mounting a second member on the first member.

[0002]

2. Description of the Related Art FIG. 7 shows an electric junction box 1 to which this kind of member mounting structure is applied (actually open flat 2-106665).
(See Japanese Utility Model Publication No. 1-109182).

The electric junction box 1 closes a box body 3 which is a first member for accommodating various electric parts such as fuses and relays (not shown) and an opening 5 formed in the upper portion of the box body 3. And a cover 7 which is a second member for On both side surfaces 3a in the width direction of the box body 3, projections 9 having an inclined surface on the opening 5 side are projected, and on the side surfaces 7a in the width direction of the cover 7, a flexible locking frame 11 is projected. 9 is extended downward.
The cover 7 is attached to the box body 3 by locking the flexible locking frame 11 to the protrusion 9.

On one side surface 3b in the longitudinal direction of the box body 3, engaging recesses 13 are provided at both ends and in the center, and slits 16 are provided on both sides between the engaging recesses 13. Two flexible locking arms 15 provided are formed. On the surface of the flexible locking arm 15, a locking projection 17 having an inclined surface is provided so as to project downward.

The bracket 19, which is a member to be attached, has a plate shape bent into an L shape, and is disposed, for example, at a predetermined position on a vehicle body panel (not shown). An engaging portion 21 to be engaged with the engaging recess 13 is provided at a tip end portion of the bracket 19, and an engaging hole 23 for engaging with the engaging protrusion 17 is provided in the bracket 19 in a flexible manner. It is formed in two places corresponding to the arm 15.

To attach the electric junction box 1 to the bracket 19, the engaging recess 13 of the box body 3 is attached to the bracket 19.
It engages with the engaging portion 21 and is pressed. As a result, the flexible locking arm 15 bends, the locking projection 17 projects into the locking hole 23, the flexible locking arm 15 returns to the initial state, and the locking projection 17 fits into the locking hole 23. Lock.

[0007]

However, in the mounting structure as shown in FIG. 7, there is a gap between the engaging portion 21 and the engaging concave portion 13 for facilitating the engagement. , Rattling may occur after installation.
The return state of the flexible locking arm 15 after attachment to the bracket 19 may be insufficient, and the cover 7 may be easily removed from the box body 3 after attachment, resulting in lack of reliability in the attachment state. .

[0008] Therefore, an object of the present invention is to provide a member mounting structure which is free from rattling and can be surely connected.

[0009]

In order to achieve the above object, the present invention provides a mounted member, a first member mounted on the mounted member, and a second member mounted on the first member.
And the engaging member and the locking hole are provided in the mounted member, and the engaging recess is engaged with the first member and the engaging hole is engaged with the engaging hole. A flexible locking arm having a locking projection, the engaging portion is engaged with the engaging recess, and the locking projection is locked in the locking hole, and A mounting structure for mounting the first member on the back side of the flexible locking arm of the first member, and the second member is inserted into the recessed part. The configuration is such that a convex portion that presses the back surface of the flexible locking arm is provided.

[0010]

The locking projection provided on the first member is locked in the locking hole provided on the mounted member, and the convex portion of the second member is set to the first position.
When it is inserted into the concave part of the member, the convex part presses the back surface of the flexible locking arm toward the engaging concave part, the locking contact portion between the locking projection and the locking hole increases, and the engaging part is opened. Since it is sandwiched between the flexible locking arm and the engaging recess, it is possible to obtain a reliable connected state without rattling. Further, in this state, since the flexible locking arm cannot bend, the connected state can be maintained.

If the locking projection does not completely project into the locking hole, the protrusion cannot be inserted into the recess. Therefore, when the second member is attached to the first member, the first member is to be attached. It is possible to detect whether or not the attachment state to the member is sufficient.

EXAMPLES Next, examples of an electric junction box to which the present invention is applied will be described. The same components as those of the electrical junction box shown in FIG. 7 are designated by the same reference numerals in the drawings, and duplicate description will be omitted.

FIG. 1 is a perspective view showing a state before attachment of an electric connection box 25 according to this embodiment, FIG. 2 is a side sectional view of FIG. 1, and FIG. 3 shows a box body 27 attached to a bracket 19. 5 is a side sectional view showing a state, FIG. 4 is a side sectional view showing a state in which the cover 29 is attached to the box body 27, FIG.
[Fig. 5] is an enlarged view of a portion A in Fig. 4.

On the back surface of the flexible locking arm 15 of the box body 27, two recesses 31 are provided which are open to the opening 5 side. Further, on one side surface 29b in the longitudinal direction of the cover 29, two convex portions that are inserted into the concave portion 31 and press the back surface of the flexible locking arm 15 are extended downward.

To attach the electric connection box 25 to the bracket 19, first, the engaging recess 13 of the box body 27 is engaged with the engaging portion 21 of the bracket 19 and pressed. As a result, the flexible locking arm 15 bends, the locking projection 17 projects into the locking hole 23, the flexible locking arm 15 returns to the initial state, and as shown in FIG. 17 is locked in the locking hole 23.

Next, while inserting the convex portion 33 into the concave portion 31, the flexible locking frame 11 is locked to the protruding portion 9 to mount the cover 29 on the box body 27. At this time, as shown in FIGS. 4 and 5, the convex portion 31 presses the back surface of the flexible locking arm 15 so that the flexible locking arm 15 is accommodated in the housing concave portion 1.
Bend to 3 side. As a result, the locking projection 17 is pressed into the locking hole 23 and further projects from the initial state, so that the locking contact portion between the locking hole 23 and the locking projection 17 increases.
Therefore, the locking projection 17 is securely locked in the locking hole 23,
The attachment state of the cover 29 to the box body 27 becomes reliable. Further, in such a state, the flexible locking arm 15 cannot be bent toward the box body 27 side, so that the attached state can be reliably held.

Further, since the flexible locking arm 15 is pressed by the convex portion 33 and bends toward the accommodating concave portion 13 side, the bracket 1
9 is sandwiched between the flexible locking arm 15 and the engagement recess 13. Thereby, even if there is a gap between the engaging portion 21 and the engaging recess 13, it is possible to prevent rattling between the two.

Further, when the locking projection 17 does not completely project into the locking hole 13, that is, in a so-called semi-fitting state, the convex portion 33 cannot be inserted into the concave portion 31, so that the cover 29 is provided with the cover 29. When attached to 27, the half-fitted state can be detected.

The present invention is not limited to the above-mentioned embodiment, but as shown in FIG.
7 may be in the form of one plate, and in this case, the protrusion 3
A recess (not shown) is formed in conformity with the shape of 7.

[0020]

As described above, according to the present invention, the first member can be attached to the attached member so as to prevent the rattling and to obtain a reliable attached state.

Further, when the second member is attached to the first member, it can be detected that the attachment state to the attached member is insufficient.
