Description

[Detailed description of the invention] [Technical field of invention] The present invention relates to a connection socket.

[Technical costs of the invention and its problems] In 43 outboard vehicles where the fuel tank is provided separately from the engine, a configuration has been adopted in which the fuel tank and the Vl-bullet are detachably connected. , a socket and a plug are used for this connection.

A conventional outboard motor connection socket 1 has a connecting part 3 for a small base 2 at the bottom of the socket main body 1, as shown in a longitudinal section in FIG. A valve chamber 4 is formed in -C, and a ball valve 5 is installed inside this JR chamber 4. The ball valve 5 and the seal 86 are crimped by a spring 7 to form a seal 86. Then, attach this socket to the socket body 1 (
= 1 Plug 901 due to the installed clip E3! ! The connecting pipe 12 on the side plug 9, which is connected to the step part 11 of the guide plug 10, resists the spring 7 against the ball valve 9, which is formed in the end face of the sealing material 6. J, sea urchin 6 where the socket side and plug side are in communication state by pushing in
The blade is made of 7g. .

In this way, the conventional socket is configured to have a seal by the ball valve 5 and a seal by 45 when connected to the plug 9! In addition, if the sealing part of the sealing material 6 is damaged when the plug is connected, the fuel will leak directly into the I5,
There was a risk that the fire's source would become a prisoner.

[[Target] of the invention]

This invention is based on the lack of the above-mentioned conventional technique i÷1.
The purpose of this is to eliminate this problem, and there are I, B, and C, which prevent fuel from leaking even if the seal member is damaged, and C, which promotes continued use of the socket.

[Summary of the invention]

In order to achieve the above object, the present invention provides a socket that fits into a plug and is connected by a clip attached to the socket body, in which two sealing surfaces are provided on the inner peripheral surface inside the valve chamber of the socket body. Fit the sealing member and press the button on the socket body. The seal of the valve body installed in the chamber is sealed by the sealing surface on the inner side of the sealing member, and the sealing when the plug is connected is sealed by the two sealing surfaces of the sealing member. be.

[Embodiments of the invention]

Embodiments of the present invention will be described below with reference to FIGS. 1 to 3, using the same reference numerals for parts common to those in FIG. 4.

In the embodiment shown in FIGS. 1 and 2, -C shows a case where the valve body 15 on the socket side opens and closes the crushed body 16 on the plug 9 side. Plug 9 is plug case 1
A plug body 13B is fixedly attached to 3A by screws or the like, and this plug body 13134 is integrally provided with a guide plug 10 and a connecting pipe 12 as shown in the conventional plug shown in FIG.

A valve body 15 is slidably inserted into the valve chamber 4 of the socket body 1, and this valve body 15 has a bowl-shaped cross section with a protrusion 15A at the tip, and has a through hole 15 [3 or Enjoy the slit
do. The back of the valve body 15 is pressed by the spring 7 and the valve body 1
The outer periphery of the socket body 1 is in close contact with the inner seal surface 1B of the seal member 17 which is selectively attached to the inner peripheral surface of the socket body 1, so that a single seal is formed.

This seal portion 4417 has two seal surfaces 18° and 19, the inner seal portion 18 is for sealing the valve body 15 on the socket side as described above, and the inner and outer seal portions 18.
19 is tightly sealed to the outer periphery of the plug body 13B when connected to the plug 9.

A ball-shaped valve body 1G is housed inside the plug body 1313 of the plug 9, and a sealing member 20 fitted in the 1" pant between the valve bodies 1313 and 1313 is individually sealed by the back pressure of the spring 21. I'm on.

A clip 8 is attached to the outer periphery of the socket body 1.
Therefore, the tip 8a of the clip 8 tends to protrude into the cut flower 1a of the socket body 1 due to the force of the spring 23. The stepped portion 2 formed on the outer periphery of the plug 9 when it is fitted into the plug 9.
4 so that it can be freely engaged with. During this engagement, the valve body 16 of the plug 9 is pushed by the protrusion 15A of the valve body 15 in the socket body 1 and opens against the spring 21, so that the plug 9 and the socket communicate with each other.

Next, the effect will be explained.

When connecting the socket I to the plug 9, insert the connecting pipe 12△ of the plug 9 into the valve 3-: of the socket body 1.

At that time, hold the clip 8 with your finger and insert the tip 8a into the valve chamber 4.
Retract it from the inner circumferential surface of. In this way, socket body 1
When 111′i is further applied to the plug 9, the protrusion 15Δ of the valve body 15 in the socket body 1 hits the valve body 14 in the plug body 13 (3) of the plug 9, and presses against the phase 7j, causing both to spring together. 7. Against 21 ((retract, sealing material 17.
20, the plug 9 and the inside of the socket body 1 are brought into communication. Then, by attaching the tip of the clip 8 to the stepped portion 24 on the outer periphery of the plug 9,
It is connected so that it will not come off. At this time, the two sealing surfaces 18 and 19 of the sealing material 17 of the socket body 1 are closely fitted to the outer peripheral surface of the plug body 1313 of the plug 9 to maintain sealing performance during connection. Therefore, even if either of the sealing surfaces 1B or 19 is damaged, the other sealing surfaces will perform the sealing function to prevent fuel leakage and prevent fuel from burning! Fires caused by leaks can be prevented.

To remove it from the socket 1, press the clip 8 to remove the tip 8 from the IQ part 24, and then remove the valve body 13 from the center fJ.
1/l is pushed back into the socket 1 by the spring 7.21 and the valve body 15 inside the main body 1 is pushed back by the inner sealing surface 18 of the sealing material 17.
The plug 9 side is sealed by the valve body 16 hitting the sealing material 20.

〔Effect of the invention〕

As explained in Section 1, the present invention provides a socket I to J3 that fits into the plug and is connected to the socket 1 by a clip provided on the main body, and an inner part inside the valve chamber of the socket main body. A sealing member with two sealing surfaces is fitted on the circumferential surface, and the seal of the valve body installed in the valve chamber of the socket body is sealed with the sealing surface on the back side of the sealing member. Since the seal is made to seal with the two sealing surfaces of the sealing member, even if one of the sealing surfaces of the sealing member is damaged and fails to seal, the other sealing surface can perform the sealing function, and the fuel, etc. It is possible to reliably prevent the discharge and prevent the risk of fire.

Further, as in the illustrated embodiment, if the clip of the socket is avoided at the stepped portion of the outer periphery of the plug, there are fewer protrusions at that portion, which is advantageous in simplifying the structure.
