Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improved grommet connecting structure for fixing automobile parts and the like to a predetermined panel.

[0002]

2. Description of the Related Art As a conventional connecting structure of this kind, for example,
There is one disclosed in Japanese Utility Model Publication No. 55-117616.
Although not specifically shown, the conventional connection structure is such that, when a synthetic resin grommet is formed, the flange portions of the grommet bodies are formed in series through a connecting piece that can be separated from each other so that adjacent grommet bodies are formed. It is configured to connect the two together in series.

Therefore, under the conventional connecting structure, the grommet main body side integrally connected in a serial state is gripped, and each grommet main body is inserted into each mounting hole formed on the panel side, Only by forcibly disconnecting the connecting piece, it is possible to install each grommet body in the corresponding mounting hole, so there is no need to worry about loss as compared with the normal grommet that is molded individually. In addition, the handling of the grommet body is very good, the work for attaching the grommet main body to each mounting hole is simple, and it is extremely convenient in terms of counting management.

[0004]

However, in such a conventional connecting structure, it is apparent that, when forming the grommet, the flange portions of the grommet body are formed integrally through a connecting piece that can be separated. Then, although it seems to be based on a rational idea, on the other hand, the number of grommet bodies to be connected is determined by the size of the molding die, so that it is necessary to obtain the desired number of connected states. However, in addition to having the problem of being limited in number, in order to connect the flange parts of adjacent grommet bodies with connecting small pieces that can be separated in order, it is necessary to provide a small mold groove on the molding die side. There was also a risk of lowering the value.

[0005]

The present invention was developed in order to effectively solve the problems of the conventional connecting structure, and each of them is based on the connecting structure in which the grommet bodies are detachably connected. A grommet body that is independent of each other and a band-shaped connecting means that is formed separately from the grommet body are provided, and holding holes for holding the grommet body are formed at regular intervals in the longitudinal direction of the connecting means. At the same time, a structure is adopted in which a separation portion is formed between the holding holes. Further, particularly in this case, it is preferable to use the material of the seal washer for the belt-shaped connecting means.

[0006]

Therefore, according to the present invention, if each grommet body is held in each holding hole formed in the longitudinal direction of the connecting means, each grommet body is sequentially connected in series via the connecting means. After that, after inserting it from the top grommet body into the mounting hole of the corresponding panel and pulling the remaining part, it will be positioned between the top grommet body and the next grommet body. Since the disconnection part of the connecting means is easily separated, it is possible to easily attach the grommet body in the connected state to the mounting holes of each panel by repeating the same work from the second grommet body. Becomes

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will now be described in detail with reference to one embodiment shown in the drawings. The connecting structure according to this embodiment is different from the conventional structure, and as shown in FIG. It is characterized in that a main body 1 of each grommet is connected to each other in series through a separately formed connecting means using a synthetic resin.

To explain this concretely, in the present embodiment, generally, the flange portion 2 of the grommet body 1 is generally used.
It was developed focusing on the use of a sponge-like seal washer attached to the lower surface as the connecting means. The body 4 of each grommet body 1 is arranged in the longitudinal direction of the long material 6 for obtaining the seal washer. Holding holes 7 for holding the holes are formed at regular intervals, and a separating portion 8 having a slit 9 or the like for facilitating the separation is formed between the respective holding holes 7, 7. It is what you have done. It should be noted that the seal washer material 6 is provided with a cut-off portion 8 having a shape corresponding to the flange portion 2 of the grommet body 1 and a slit 9 and the like at the same time when the holding hole 7 is punched out. To do.

On the side of the grommet body 1, the flange portion 2 and the pair of temporary fixing locking legs 3 are provided.
Although the screw hole 5 into which the screw is screwed is defined in the body portion 4, the structure of the grommet body 1 itself is not a characteristic part of the present invention, and thus various other The known structure may be changed depending on the implementation.

Therefore, in actual use, if the body portions 4 of the grommet main body 1 which are independent from each other are held in the respective holding holes 7 formed in the long material 6 as the connecting means, it is shown in FIG. As described above, since each grommet body 1 is sequentially connected in series via the material 6,
By inserting the first grommet body 1 into the corresponding mounting hole (not shown) on the panel P side and pulling the remaining connecting portion, as shown in FIG. 3, the first grommet body 1 and the next grommet body The separation portion 8 of the material 6 located between the two will be easily separated. Therefore, after that, by repeating the same operation from the second grommet body 1, it is possible to easily attach the grommet body 1 in the connected state to the mounting holes of each panel P, and at the same time, to connect the above-mentioned connection. If the state is used, it becomes very convenient in terms of component feeding even when this mounting work is carried out by a machine.

In addition, in this embodiment, since the material 6 of the seal washer is used for the connecting means of the grommet body 1, each connected grommet body 1 is inserted into the mounting hole and separated at the same time. As shown in the figure, it is possible to automatically interpose a normal seal washer W between the lower surface of each flange portion 2 and the surface of the panel P. From this point as well, rationalization of workability can be greatly expected, and conventional As described above, there is no fear of lowering the molding efficiency of the grommet itself. In addition, since the length dimension of the material 6 itself of the seal washer can be freely determined, it goes without saying that there is no concern that the number of the grommet main bodies 1 to be connected is limited. Therefore, by connecting the used number of grommet main bodies 1, it is possible to prevent forgetting to assemble them.

The above embodiment uses the material 6 of the seal washer as the connecting means from the viewpoint of the advantages described above, but the present invention is not limited to this. Although not shown in the figure, even if other long film-shaped strips are used and the holding holes 7 and the cut-off portions 8 similar to those described above are applied to the film-shaped strips, each grommet body 1 It becomes possible to connect each other in series in order. However, under the use of such a film strip,
When the seal washer W is required, unlike the above embodiment, the seal washer W is attached to the connected grommet main body 1 side later, but when the seal washer W is not required, On the contrary, it becomes more rational to use a film-shaped strip, and if the film-shaped strip has an extremely thin wall thickness, the presence of the film-shaped strip may hinder the function of the grommet body 1. Not at all.

[0013]

As described above, according to the present invention, by adopting the above-mentioned structure, it is possible to freely connect an arbitrary number of grommet bodies, so that there is a numerical limitation and a molding efficiency in the conventional connection structure. It has become possible to completely eliminate the decline. In addition, if the material of the seal washer is used for the connecting means, the work of individually mounting the seal washer on the grommet body is not necessary at all, so it goes without saying that it is a win-win. It will be very easy to install automatically.
