Abstract

PROBLEM TO BE SOLVED: To smoothly carry out connection/disconnection between a socket main body and a plug main body by forming a folded part in the connection part between a sleeve and the base end of a claw member in a fluid coupling in which the claw member is engaged in a recess part of the plug main body when the plug main body is inserted into the socket main body. SOLUTION: When an insertion cylinder part 12 of a plug main body P is inserted into a connection cylinder part 4 of a socket main body S, a circular arc upper part 12a in the insertion cylinder part 12 collides against a claw part 8 of a claw member (n) at first, and when the insertion cylinder part 12 is pushed into the connection cylinder part 4 further, a sleeve 5 is moved against a compression spring 6 by means of the pushing force, while the claw part 8 is retracted from a guide hole 10 at the same time. If the insertion cylinder part 12 is pushed into the connection cylinder part 4 to the further extent, the claw part 8 is dropped in a recess part 13. In this process, as a U-shaped folded part 7 is arranged in the connection part between the claw member (n) and the sleeve 5, the folded part 7 can be bent easily when the sleeve 5 is slid, so that the sleeve 5 can be slid smoothly.

In the conventional fluid coupling as described above, since the base end of the claw member is directly connected to the inner surface of the sleeve, stress concentrates on the connection portion. In order to withstand the stress concentration, it was necessary to increase the strength of the connecting portion. However, as the strength of the connecting portion is increased, the elasticity of the portion is lessened, and the base end of the claw member is less likely to be bent. However, if the base end of the claw member is not easily bent, the sleeve does not move smoothly. If a large force is required to move the sleeve, there is a problem that a large force is required for connecting and disconnecting the socket main body and the plug main body, especially for the disconnection.

In order to solve the above problem, for example, it is conceivable to reduce the thickness of the claw member. However, when the thickness of the claw member is reduced, the strength of the claw member itself cannot be maintained. If the thickness is made too thin, the resin will not be sufficiently supplied to the thin portion during the molding, and the thickness will vary. SUMMARY OF THE INVENTION An object of the present invention is to provide a fluid coupling capable of smoothly connecting and disconnecting a socket body and a plug body by allowing a sleeve to be moved lightly without making the thickness of a claw member particularly thin. .

The first aspect of the present invention is characterized in that a folded portion is formed at a connecting portion between the sleeve and the base end of the claw member on the premise of the fluid coupling. By forming the folded portion in this way, the entire length of the claw member can be increased. As long as the material of the claw member is the same and the cross-sectional shape of the bent portion is the same, a longer claw member can bend the claw member with a smaller load than a shorter claw member. . Therefore, the claw member can be bent with a small load while keeping the material and the cross-sectional shape of the claw member the same as the conventional one. As described above, the fact that the material and the cross-sectional shape of the claw member are the same as the conventional one means that the strength can be maintained the same as the conventional one.

The most important feature of the first embodiment is as follows.
A U-shaped folded portion 7 is provided at a connection portion between the claw member n and the sleeve 5, and the folded portion 7 is connected to the claw portion 8.
The linking part 9 in the process up to the point is made substantially parallel to the axis. By forming the folded portion 7 into a U-shape as described above, stress is not concentrated even if the portion is bent. Further, by providing the folded portion 7, the entire length of the claw member n can be increased. The longer the length, the more it can bend with less force. The relationship between this force and the amount of deflection can be expressed by the following equation.

【0017】 δ=(WL3)/(3EI) δ:爪部材のたわみ量 W:爪部材をたわませるための荷重 L:爪部材の長さ E:爪部材の材料によって決まる定数 I:爪部材の断面形状によって決まる定数 上記の式からも明らかなように、その材料と断面形状と

Δ = (WL 3 ) / (3EI) δ: Deflection amount of claw member W: Load for bending claw member L: Length of claw member E: Constant determined by material of claw member I: Claw Constant Determined by Cross-sectional Shape of Member As is clear from the above equation, assuming that the material and the cross-sectional shape are the same, the longer the length L of the claw member, the more the claw member n
It becomes easy to bend. That is, even if the cross-sectional shape of the claw member is the same as that of the related art, in other words, the claw member n can be easily bent while keeping the strength of the claw member n the same as that of the related art.

Since the claw member n is easily bent as described above, when the sleeve 5 is slid as shown in FIG. 3, the folded portion 7 is easily bent. Therefore, the force required to slide the sleeve 5 can be reduced.
The fact that the linking portion 9 is made substantially parallel to the axis means that when a force in the direction of lifting the claw portion 8 acts on the claw portion 8, most of the force becomes a force for bending the folded portion 7. . Therefore, the fact that the linking portion 9 is made parallel also causes the folded portion 7 to be bent with a light force.

However, the shape of the folded portion is not necessarily limited unless the claw member is directly linked to the sleeve as in the above-mentioned conventional fluid coupling. For example, in the case of the second embodiment shown in FIG. 4, the folded portion 7 of the claw member n is made smaller, and the linking portion 9 is also angled with respect to the axis. In the case of the second embodiment,
As compared with the first embodiment, the bent portion 7 becomes harder, and even if a force acts in the direction of lifting the claw portion 8, the force is dispersed. Therefore, a slightly larger force is required when moving the sleeve 5 than in the first embodiment. However, compared to the conventional example, the force is small.

According to the fluid coupling of the first aspect, since the claw member bends with a small force, a small force is sufficient even when the sleeve is slid. That is, the operation force for connecting and disconnecting the socket body and the plug body can be reduced. In the second invention, the folded portion has a U-shape, and in the third invention, the linking portion is parallel to the axis, so that the claw member is more easily bent.
