Description

[Detailed description of the invention] (Field of industrial application) This invention is a metal retainer that is caulked to the tip of a resin inlet pipe for refilling fuel connected to a fuel tank mounted on a vehicle and is passed through a refueling gun. The present invention relates to a grounding device and is constructed so that a grounding wire can be easily fixed and does not take up much bulk.

(Prior art) Conventionally, in order to attach a ground wire that is electrically connected to a metal retainer that is caulked to the protruding end of a resin inlet pipe, it is necessary to attach the ground wire to the protruding end of the resin inlet pipe a. A gasket ring groove c and a caulking ring groove d are provided on the outer periphery of the protruding end b, and a bent recess f of a metal retainer e for oil supply is fitted into the protruding end,
The outer hem g is bent into the caulking circulation groove d and caulked h, and the terminal P of the ground wire n is attached to the tongue i protruding downward from the hem g with a rivet j, so the vehicle body k Since there is a gap o between the retainer protrusion hole l and the elastic ring m provided in the retainer protrusion hole l, making it impossible to make a close contact, gasoline odor enters the vehicle interior, etc., and the installation of the grounding member becomes expensive. There is.

(Problems to be Solved by the Invention/Objective of the Invention) The present invention connects the above-mentioned grounding member to the resin inlet pipe of the metal retainer by bending it for caulking without using rivets or the like. Further, a grounding member is secured to the inner surface of a seal ring applied to the inlet pipe to contact the inner circumference of the retainer protrusion hole of the body, so that no gap is created between the seal ring and the inner circumference of the retainer protrusion hole. The purpose of this structure is to eliminate the drawbacks of the conventional method.

(Means for Solving the Problems) The present invention has a structure that meets the above-mentioned purpose, and a metal retainer is fitted to the protruding end of a resin inlet pipe connected to a vehicle fuel tank. The outer circumferential edge of the retainer portion is bent and caulked into an annular groove provided on the outer circumference of the end, and
providing a grounding member which is electrically connected by being crimped by the caulking and bending of the retainer within the annular groove;
The earthing member is characterized in that the grounding member is engaged with the lower surface of a seal ring provided on the inlet pipe so as to contact the inner periphery of a retainer protruding hole provided in the automobile body at the lower part of the annular groove.

A preferred embodiment of the invention will now be described.

(Example) In FIG. 1, reference numeral 1 denotes a resin inlet pipe, and a gasket ring groove 3 and a caulking ring groove 4 are sequentially provided on the outer periphery of a projecting end 2. Reference numeral 5 denotes a metal oil retainer, which has a bent recess 6 connected to the above-mentioned protruding end 2.
Caulk 8 by inserting the hem 7 and bending it into the ring groove 4.
Gasket 1 fitted into gasket ring groove 3
1, an airtight seal is made between the resin inlet pipe 1 and the resin inlet pipe 1. Reference numeral 9 denotes a grounding member, and its end portion is pressed against the wall surface of the caulking ring groove 4 by the caulking 8 of the retainer 5 to create an electrical connection.

Reference numeral 10 denotes a ring-shaped seal molded by resin injection molding or the like on the outer periphery of the resin inlet pipe 1, immediately below the caulking ring groove, and is inserted into and engaged with the lower surface of a portion of the ground member 9. The connection by the caulking 8 of the grounding member 9 is fixed so as not to become loose.

(Function) The ring-shaped seal 10 is brought into contact with the circumference of the ring 23 of the retainer projection hole 22 provided in the vehicle body 21, and the metal retainer 5 has a tongue piece for connecting the grounding member 9. Since the smooth surface of the ring-shaped seal 10 is brought into contact with the ring 23, no gap is created through which gasoline odor can leak.

(Effects) As described above, the present invention eliminates the need for connecting tools to electrically and mechanically connect the grounding member to the metal retainer 5.
is bent into the caulking ring groove 4 provided on the outer periphery of the resin inlet pipe 1 and caulked 8. At the same time, a grounding member 9 is sandwiched between and connected to the pipe 1, and the earth member 9 is applied to the outer circumference of the pipe 1. The earth member 9 is configured to engage with the lower surface of a ring-shaped seal 10 which is protruded from the retainer protrusion hole 22 of the body 21 and is provided as a member for absorbing vibrations of the body. Since there is no gap between the ground member 9 and the resin inlet pipe 1 and the metal retainer 5, there is no risk of gasoline odor leaking out, and mounting tools such as rivets are used to attach the ground member 9 to the resin inlet pipe 1 and the metal retainer 5. Since it does not require any installation, it has the advantage of being easy to install and inexpensive to construct.
