Description

[Detailed Description of the Invention] "Technical Field of the Invention" The present invention relates to an improvement in a waterproof grommet that is fixed to the middle of a conduit of a plurality of control cables (hereinafter simply referred to as cables). More specifically, the present invention relates to a structure in which respective grommet cylinders (hereinafter simply referred to as cylinders) fixed to a plurality of cables can be integrated by a grommet base (hereinafter simply referred to as base).

``Prior Art'' Conventionally, there has been a structure shown in Figure 3 as a structure for waterproofly fixing two cables to the body of a vehicle using one waterproof grommet. . That is, at the base 12 of the grommet 11, there are two cylinders 13, 13' for holding the conduit.
In some cases, a slit 14 is provided in one of the cylindrical bodies (13' in FIG. 3) over the entire length, including the base 12. When assembling one cable, insert the conduit into the other slit-less cylinder 13 and secure it, then assemble one cable separately, and then complete the assembly of the other cable, which has not inserted a grommet and secured it. The two cables were assembled to one grommet by fitting and fixing the conduit into the cylindrical body 13' through the slit 14 provided in the cylindrical body 13' of the grommet which was fixed to one of the cables. state is being carried out.

As mentioned above, in the case of a grommet that has a slit in one of the cylindrical bodies of the grommet, and a grommet that does not have a previously existing slit, it is necessary to insert two conduits at the same time into the cylindrical body of the grommet in advance. Under such conditions, the assembly of the cable becomes extremely difficult due to the addition of complicated factors such as different lengths of the conduits and different parts to which they are fixed. Therefore, as described above, a slit is provided in one of the cylindrical bodies of the grommet, and another cable is later fitted and fixed through the slit, thereby integrating the two cables. However, in the case of grommets with slits as mentioned above, if rainwater etc. comes into contact with the grommets after the cable is attached to the car body, the slits will absorb the water through capillary action and the water will enter the car interior, causing damage to the car body. This causes rust to occur. As a preventive measure, it is necessary to apply caulking material around the slit to make it waterproof. However, such waterproofing measures cannot be completely perfect, and at the same time, the inconvenience of having to go through the extra process of applying caulking material is unavoidable.

``Purpose of the invention'' As mentioned above, the present invention eliminates the drawbacks of conventional waterproof grommets for cables, and provides a waterproof grommet with a structure that can easily hold multiple cables and provide a reliable waterproof effect. The purpose is to

``Structure of the invention'' In order to achieve the above-mentioned purpose, the base and the cylindrical body are separated, the cylindrical body is fixed to the conduit, the cable is assembled, and finally the cylindrical body engagement hole (hereinafter simply referred to as engagement hole) is drilled in the base. The cylindrical body is engaged with the mating hole (referred to as a mating hole) and joined together, so that a plurality of cables can be integrally assembled into the same grommet.

``Embodiments'' Next, the grommet of the present invention will be explained with reference to the drawings, but the present invention is not limited to such embodiments.

Fig. 1 is a partially cutaway side view of the main parts of an embodiment of the waterproof grommet of the present invention, which is disassembled into individual parts, and Fig. 2 is a partially cutaway side view of the main parts showing a state in which the individual parts of Fig. 1 are assembled. It is a diagram.

In FIG. 1, cylindrical body engaging holes 2, 2' are bored in the grommet base 1, and the cylindrical body engaging holes 2, 2'
Annular projections 3, 3' are provided within 2'. On the other hand, the cylinders 4, 4' which can be fixed to the conduit A are provided with annular grooves 5, 5' which can engage with the annular projections 3, 3'.

In such a configuration, first, the cylindrical bodies 4, 4' are fitted and fixed in respective predetermined positions of the cable conduit, and then the assembly of the cable is completed, and then the base 1
The assembled cables are inserted into the respective engagement holes 2 and 2' drilled in the base, and the cylindrical bodies 4 and 4' are fitted and engaged with the engagement holes 2 and 2', as shown in FIG. 1 and the cylindrical bodies 4, 4' are completely combined into one body, resulting in a state as shown in FIG. 2 in which two cables are assembled to one grommet.

``Effect of the invention'' In the grommet of the invention, the base 1 and the cylindrical bodies 4, 4' are completely separate, so when assembling the cable, the predetermined position of each conduit is completely independent of the base 1. Cable assembly is extremely easy because the cable assembly can be completed after the cylinder is inserted and fixed in place, and the cylinder does not have slits like conventional ones, so it can be sealed with caulking material etc. The engagement holes drilled in the base may not only be drilled approximately parallel to each other as shown in this embodiment, but may also be The present invention is particularly effective when the dowels intersect at a certain angle, and the present invention can produce each of the extremely excellent effects described above.
