DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure for fixing a connector to a mounting panel such as an automobile body panel.

[0002]

2. Description of the Related Art FIG. 3 is a perspective view of a power supply component of a lighting apparatus described in Japanese Utility Model Laid-Open No. 54-90974, and FIG. For example, a connector can be used as the power supply component. Hereinafter, the power supply component will be described as a connector.

[0003] As shown in FIG. 3, a terminal (not shown) is inserted into a connector block 2 of the connector 1, and is attached to a mounting panel 3 such as a vehicle body panel in a state in which the terminal is accommodated. A pair of elastic leg portions 4 are integrally formed on both side surfaces of the connector block 2 so as to extend downward. A hook-shaped hook 5 is formed at the tip of the leg 4, and the connector 1 is fixed by hooking the hook 5 on the mounting panel 3. Numeral 6 denotes a plurality of ridges 6 formed on the outer surface of the hook portion 4 in the vertical direction, so as to make the leg portions slippery when the leg portions are inserted into the mounting panel 3.

[0004] The mounting to the mounting panel 3 is shown in FIG.
As shown in (a), the leg 4 faces the mounting hole 7 of the mounting panel 3. And, by utilizing the elasticity of the legs 4,
As shown in (b), the pair of legs 4 is pushed in the direction in which the distance is reduced, and in this state, the legs 4 are pressed into the mounting holes 7. After this press-fitting, when the force on the leg 4 is released, the leg 4 returns to its original state due to its elasticity, and the hook 5 is attached to the mounting panel 3.
Engages the lower surface of. Thereby, the connector 1 can be fixed to the mounting panel 3.

[0005]

However, in the conventional mounting structure, since a pair of legs 4 are pressed into the mounting hole 7 at the same time, a large force is required for press-fitting, and there is a problem that it is difficult to press-fit. In addition, the elasticity of the leg portion 4 tends to decrease with time, which causes a problem that the engagement force with the mounting panel 3 is weakened and rattling occurs.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems. A connector which can be easily mounted and can be fixed without rattling even when the mounting force is small. An object of the present invention is to provide a mounting structure.

[0007]

In order to achieve the above object, according to the first aspect of the present invention, a hook portion and a clamp portion are formed in a protruding shape at intervals on a surface of a connector block facing a mounting panel. The clamp portion is fixed by pushing the clamp portion into the clamp hole of the mounting panel in a state where the hook portion is hooked on the hook hole of the mounting panel, and the hook between the hook portion and the clamp portion is fixed. A protrusion protruding in the direction of the mounting panel is formed near the portion.

In this structure, the connector block is fixed to the mounting panel by hooking the hook portion into the hook hole of the mounting panel and then pushing the clamp portion into the clamp hole of the mounting panel. The projection provided near the hook portion is in contact with the mounting panel when the clamp is pushed in, and serves as a fulcrum when the clamp is pushed in. Therefore, since the connector block rotates on the principle of leverage, the clamp portion can be pushed in with a small force.

In the fixed state of the connector block, the distance between the hook and the clamp does not change, and the state of engagement between these and the mounting panel does not change. For this reason, it is possible to fix without rattling.

According to a second aspect of the present invention, in the first aspect of the present invention, the connector block has a convex portion protruding stepwise in the direction of the mounting panel between the hook portion and the clamp portion, The protrusion is a corner of the protrusion on the hook side.

[0011] By making the projection serving as a fulcrum at the time of pushing the corner of the projection, it is not necessary to separately form the projection. Therefore, the shape of the connector block becomes simple, and the molding becomes easy.

A third aspect of the present invention is the invention according to the first or second aspect, wherein the outer surface of the projection is curved.

The curved projection can be easily rotated with respect to the mounting panel, and can be smoothly rotated when the clamp is pushed in, so that the mounting operation is simplified.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a side view of an embodiment of the present invention before mounting, FIG. 2 is a side view of the mounted state, 8 is a connector block, 9 is a vehicle body panel to which the connector block is mounted, and the like. Panel.

The connector block 8 is a member fixed to the mounting panel 9, and includes a connection box main body of an electric connection box to which a fuse and a relay are mounted, a connector housing as a connector main body containing terminals, and a connection box main body. The connector block 8 may be a lower cover to which the connector housing is attached, an upper cover that covers the upper surface of the connection box body or the connector housing, or other members. A hook portion 11 and a clamp portion 12 are formed in a projecting shape on a lower surface 10 of the connector block 8 which is a surface facing the mounting panel 9.

The hook 11 is located at one end of the connector block 8 (the left end in the illustrated embodiment). The hook portion 11 has a hook shape facing the opposite side of the clamp portion 12, and is integrally connected to a tip of a hanging portion 13 hanging from the lower surface 10 of the connector block 8. The hook portion 11 is provided with a hook hole 1 formed in the mounting panel 9.
4, the hook hole 14 hooks and engages with the hook hole 14.

The clamp portion 12 is formed on the other side (right side) of the lower surface 10 of the connector block 8, and
1 and an interval. The clamp portion 12 includes a press-fit portion 16 press-fit into a clamp hole 15 formed in the mounting panel 9 and a large-diameter contact portion 17 formed in an umbrella shape above the press-fit portion 16 as shown in FIG. As shown in FIG.
The mounting panel 9 is engaged with the mounting panel 9 by sandwiching the mounting panel 9 between the mounting panel 9 and the contact portion 17. In this case, the outer surface of the press-fit portion 16 is a tapered surface whose diameter gradually decreases downward, so that the press-fit into the clamp hole 15 is facilitated.

A protrusion 18 is formed between the hook 11 and the clamp 12 on the lower surface 10 of the connector block 8. The convex portion 18 is provided so as to extend in the length direction of the connector block 8 and at a position close to the hook portion 11. The projection 18 is necessarily provided on the connector block 8 as necessary for fixing the electric connection box and the connector and other functions as needed.

The convex portion 18 has a shape protruding in the direction of the mounting panel 9, and has a lowermost flat surface 19 in contact with the mounting panel 9, both ends of the flat surface 19, and the connector block 8.
Are formed by corner portions 20 and 21 which are provided continuously with the lower surface of the slab. Of these, at least the outer surface of the corner portion 20 located on the hook portion 11 side is an arc-shaped inclined surface, which contacts the mounting panel 9 at the time of mounting, which will be described later, and can smoothly rotate in this contact state. .

Next, the mounting procedure of this embodiment will be described. First, as shown in FIG. 1, the hook 11 is inserted into the hook hole 14 of the mounting panel 9 with the connector block 8 inclined. By this insertion, the hook portion 11 engages with the mounting panel 9 in a state in which the hook portion 11 does not come off.

Next, as shown by an arrow F in FIG. 1, the clamp section 12 side of the connector block 8 is pressed toward the mounting panel 9. By this pressing, the hook portion 11 of the convex portion 18 is formed.
The side corner portion 20 abuts the mounting panel 9. Thereafter, by continuing the pressing in the F direction, the connector block 8 approaches the mounting panel 9 while rotating, with the corner portion 20 of the convex portion 18 in contact with the mounting panel 9 as a fulcrum. That is, the connector block 8 pivots on the principle of leverage with the corner 20 as a fulcrum and the hook 11 as a fixed point. Therefore, it can be easily rotated with a small pressing force. At this time, since the corner portion 20 has an arcuate outer surface, the corner portion 20 rotates while being in contact with the mounting panel 9. For this reason, the rotation of the connector block 8 is performed more smoothly, and the operation with a smaller pressing force is possible.

By the rotation of the connector block 8, the clamp portion 12 reaches the clamp hole 15 of the mounting panel 9, and the press-fit portion 16 is press-fitted into the clamp hole 15.
The clamp portion 12 sandwiches and engages the mounting panel 9 between the press-fit portion 16 and the contact portion 17, whereby the connector block 8 is fixed to the mounting panel 9.

In the fixed state, the distance between the hook 11 and the clamp 12 does not change, and the state of engagement with the mounting panel 9 does not change. Therefore, the connector block 8 can be stably fixed without rattling.

In the present invention, a projection is formed on the lower surface of the connector block 8 at a position near the hook 11 without forming the projection 18 on the lower surface, and the projection is used as a fulcrum. The principle may be applied. Also, the outer surface of the corner portion 20 of the convex portion 18 may be a straight tapered surface without being formed in an arc shape.

[0025]

As described above, according to the first aspect of the present invention, the protrusion provided near the hook portion serves as a fulcrum when the clamp portion is pushed in, and the connector block pivots on the principle of leverage. Therefore, the clamp portion can be pushed in with a small force and can be easily attached. Further, in the fixed state, the distance between the hook portion and the clamp portion does not change, and the engagement state between these and the mounting panel does not change. Become.

According to the second aspect of the present invention, since the protrusion serving as a fulcrum at the time of pushing is a corner portion of the protrusion, it is not necessary to separately form the protrusion, and the shape of the connector block is simplified. Molding also becomes easy.

According to the third aspect of the present invention, since the projection is curved, the rotation is easy, the rotation when the clamp is pushed in is smooth, and the mounting operation is simplified.
