Description

[Detailed description of the invention] (Field of industrial application) This invention relates to a resin filler pipe, and when using a metal filling port pipe, there is a fuel flow charge (static electricity) caused by fluid friction during refueling. In order to remove the above-mentioned filler pipe by connecting the ground wire to the earth, the structure is such that when installing the filler pipe to the automobile chassis or body using a mounting screw, the earth wire can be connected at the same time without forgetting to do so.

(Prior art) A filler pipe that connects the metal filling port pipe exposed from the center hole of a rubber gasket provided in the body and the filling port of the fuel tank is molded from synthetic resin, and liquid fuel flows through the filler pipe. Measures have already been taken to prevent charging due to Also, although it is possible to ground the metal filler pipe regardless of the installation of the filler pipe to the automobile body or chassis, it is not possible to connect the filler pipe and ground the metal filler pipe. unknown.

(Problem to be solved by the invention) Even if the filler pipe a is molded from synthetic resin, the supply port pipe d protruding from the center of the rubber gasket c of the body b is made of metal, so it cannot be filled with liquid fuel. It is inevitable that the resulting friction will cause electrification, and therefore the supply port pipe d must be grounded to the body or chassis. Figure 6 shows an example of conventional grounding, in which a metal supply pipe d and a body b are connected by a ground wire e; Since this has to be done when attaching the ground wire d to the body, it is not only troublesome to install, but also has the disadvantage that it is easy to forget to connect the ground wire e to the body b.

(Means for Solving the Problems) In view of the above, the present invention aims to ensure that the earth connection is not forgotten. By inserting the flanged terminal tube to be connected and fitting the screw passed through the center hole of the terminal tube into the mounting hole at the required position on the body or chassis and attaching the filler pipe, the supply port tube can be automatically grounded. This is what I did.

(Example) In Figs. 1 to 5, 1 is a filler pipe body made of synthetic resin, and a connection plate 2 having a thickness approximating the thickness of the pipe wall is protruded from the back part of the filler pipe body. Then, an air vent tube 3 bent approximately parallel to the main body 1 is integrally molded. Furthermore, U-shaped ground wire clips 4 arranged substantially parallel to the connecting plate 2 are integrally formed on the outer surface of the filler pipe main body 1 at appropriate intervals.

The resin filler pipe main body 1 is a metal filler pipe 1 that protrudes from the center hole of a rubber packing ring 15 fitted into an opening 14 of an automobile body 13.
The air vent pipe 3 has one end opened inside the part fitted externally to the pipe part 12, and the other end opened from the top surface of the fuel tank 16. It is connected to the protruding air escape pipe 17 via a hose 18.

The degree of protrusion of the connecting plate 2 is increased near the end of the air venting pipe 3 to which the rubber hose 18 is connected, the air venting pipe 3 is bent, and a mounting hole 5 is provided through the connecting plate 2 at the bent part. 6 is a ground wire whose one end is connected to the supply port pipe 11 by soldering or the like;
The terminal ring 7 is installed by pinching the ground wire between the ground wire clips 4 and guiding it near the mounting hole 5. Reference numeral 8 denotes a terminal tube having a bolt insertion hole 8a in the center, and the resin filler pipe body 1 is directly attached with a bolt or the like, and the above-mentioned mounting is done so that the stress relaxation of the resin does not cause a decrease in the mounting torque. While tightly fitting the terminal ring 7 into the hole 5, the terminal ring 7 is inserted into the third
Pinch as shown.

19 is a mounting piece for the resin filler pipe main body 1 provided on the automobile chassis or body;
As shown in the figure, a mounting hole 20 is provided through which the mounting bolt 21 passed through the center hole of the terminal tube 8 passes through, and the bolt 21 is fixed with a nut 22 to attach the resin filler pipe body 1 and the ground wire 6. Ground the body of the supply port pipe 11 at the same time.

(Operations and Effects of the Invention) The present invention has the structure clarified by the explanation of the above-mentioned embodiments, and has a resin filler pipe body 1.
At the same time, the earth wire 6 of the supply port pipe 11 can be connected to the body or the chassis for grounding. , fit the flanged terminal tube 8 to which the ground wire 6 is connected into the mounting hole 5 for the above-mentioned installation, pass the bolt, screw, or other mounting screw that passes through the mounting hole 5 through the center of the terminal tube 8, and insert the resin filler. Since the pipe main body 1 is attached to the body, chassis, etc., there is no risk of forgetting to ground, and the above-mentioned action also prevents forgetting to connect the ground wire 6 of the supply port pipe 11. , it is possible to automatically carry out grounding work, and it also has the effects of being able to create a structure suitable for resin filler pipes.
