As shown in FIG. 4, the connection structure includes branch pipes 100 branching in three directions, and hoses 201, 202 inserted into respective branch pipes of the branch pipes 100.

れる。To form this hose connection structure, the branch pipes of the branch pipe 100 are connected to the hoses 201 to 203, respectively.
Insert Thereafter, a branch pipe (hereinafter, referred to as an insert) to which the hose is attached is placed in a mold as shown in FIG. 5, and the hose surface is pressed by seal rings 401, 402, and 403 at the ends of the respective branch cylinders to seal. And fix it. Then, molten resin is filled into the mold 500, the mold 500, the seal ring 401 to 403, and the cavity 500 formed by the insert, and the resin coating portion 300 is formed in the joint portion and the central portion of the branch pipe 100. At this time, the resin coating portion 300 contracts and solidifies at a contraction rate of 0.5% or more, so that a force of reducing the diameter acts on each hose together with the injection pressure. Accordingly, each of the hoses 201 to 203 is strongly sandwiched between the resin coating portion 300 and the branch pipe 100, and a high sealing pressure is obtained.

ある。In the above-mentioned hose having the conventional connecting portion, the inner diameter of the hose is generally the same as the inner diameter of the pipe, and the cross-sectional area of the flow path is uniform. Therefore, when inserting a hose into a pipe, it is necessary to increase the diameter of the hose. However, since a radiator hose or the like has a reinforcing yarn layer inside and a large thickness, a large force is required to expand the diameter, and for example, it may be difficult to insert the hose manually by a woman.

ない。Therefore, automation of the work of inserting a hose into a pipe has been considered. However, the inner diameter of the hose must be smaller than the outer diameter of the pipe in order to obtain a seal at the time of connection. It cannot be inserted because it interferes with the tip of the pipe. Further, it is not easy to automate such a work as a manual operation in which the relative angle between the hose and the pipe is changed in accordance with the progress of the insertion and the direction of the force is also changed while being changed.

In a hose having a connection part consisting of a resin-coated part, which is covered in general, the hose has a general part having an inner diameter substantially equal to the inner diameter of the pipe, and a diameter which is enlarged at the end of the general part and is smaller than the outer diameter of the pipe. The vulcanization is carried out in advance to a shape having a first enlarged diameter portion having an inner diameter and a second enlarged diameter portion having an inner diameter larger than the outer diameter of the pipe, which is gradually enlarged from the tip of the first enlarged diameter portion.
It is a form, the second enlarged diameter portion and a first enlarged diameter portion is characterized in that it is inserted into the pipe.

比べて小さいので、強度面の不具合も防止されている。The pipe has a function of holding and reinforcing the hose from the inside at the connection portion, and for example, a branch pipe branched in a plurality of directions can be used. The end of this pipe is inserted into a hose, and clamps the hose together with a resin coating portion described later. The greatest feature of the present invention lies in the shape of the hose. That is, the hose has a general portion having an inner diameter substantially the same as the inner diameter of the pipe, a first expanded portion having an inner diameter expanded at the end of the general portion and having an inner diameter smaller than the outer diameter of the pipe, and a distal end of the first expanded portion. And a second enlarged diameter portion that is gradually enlarged and has an inner diameter larger than the outer diameter of the pipe.
Therefore, by positioning the hose and the pipe coaxially and moving them in directions approaching each other, the hose can be easily inserted into the pipe and automation can be performed. Further, since the first enlarged diameter portion is inserted in a state where the diameter is further enlarged, the sealing property is secured, and since the amount of diameter enlargement at the time of insertion is smaller than that in the conventional case, problems in the strength aspect are also prevented. I have.

Then, one of the hose and the pipe is fixed, and the other is driven close to the axial direction, so that the hose or the pipe can be easily inserted. The resin covering portion is integrally covered with a joint between the hose and the pipe, and clamps the hose between the hose and the pipe. This resin covering portion can be formed by arranging a pipe in which a hose is inserted in a molding die, sealing it with a seal ring or the like, and molding the periphery of the joint portion by injection molding or the like.

現する。When manufacturing a hose having a connection portion according to the present invention, a hose is first inserted into a pipe. At this time, first, the second enlarged diameter portion is inserted into the pipe. Since the inner diameter of the second enlarged diameter portion is larger than the outer diameter of the pipe, when the hose and the pipe are positioned coaxially and moved in a direction approaching each other, the pipe will not be interfered with the end face of the hose. Is inserted into. Since the second enlarged diameter portion is gradually reduced in diameter toward the first enlarged diameter portion, the pipe is guided on the funnel-shaped inner peripheral surface at the boundary between the second enlarged diameter portion and the first enlarged diameter portion. First
It is inserted into the enlarged diameter part. Since the inner diameter of the first enlarged portion is smaller than the outer diameter of the pipe, the pipe is inserted while increasing the diameter of the first enlarged portion. Thereby, the pipe is brought into close contact with the first enlarged-diameter portion due to the reaction force of the first enlarged-diameter portion to reduce the diameter, and the sealing property is developed.

In the case of (1), when the specific dimensions are described, the outer diameter of the branch cylinder A is 19.6 mm and the inner diameter is 16 mm. The inner diameter of the general portion 20 is 16 mm, and the inner diameter of the first enlarged portion 21 is 17.
5 mm, and the inner diameter of the tip of the second enlarged diameter portion 22 is 20 mm. That is, the inner diameter of the first enlarged diameter portion 21 is smaller than the outer diameter of the branch tube A, and the inner diameter of the second enlarged diameter portion 22 is larger than the outer diameter of the branch tube A.

る。Therefore, when the hose B is inserted into the branch tube A, the branch jig 1 is fixed by engaging a holding jig (not shown) with the locking concave portion 12. Then, the branch tube A and the hose B are opposed to each other at the same coaxial position, and the hose B is driven in a direction axially approaching the branch tube A from the second enlarged-diameter portion 22 side. Then, since the inner diameter of the second enlarged-diameter portion 22 is larger than the outer diameter of the branch tube A, the branch tube A is easily inserted into the second enlarged-diameter portion 22. The branch tube A is guided by the funnel-shaped inner peripheral surface of the second enlarged-diameter portion 22 and inserted into the first enlarged-diameter portion 21, and the hose B contacts the central portion 12 while expanding the first enlarged-diameter portion 21. It is inserted until it touches. The other hose 2 and the branch tube 10 are inserted similarly.

Since the end surfaces of the branch tube 10 and the hose 2 do not interfere with each other, the insertion of the branch pipe 1 and the hose 2 can be easily automated. Further, since the first enlarged diameter portion 21 is formed in a state in which the diameter is enlarged in advance, the amount of the enlarged diameter at the time of insertion is smaller than that in the related art. Therefore, since the amount of deformation of the first enlarged-diameter portion 21 is small, the thickness is reduced and the deformation of the reinforcing yarn layer is reduced, thereby preventing a defect in strength.

The resin coating 3 is formed by injection molding using a glass fiber reinforced polyamide resin as a molding material in the same manner as shown in FIG. Then, the hose 2 is pressed by the injection pressure of the resin covering portion 3 and the contracting force after molding, and is firmly fastened to the branch pipe 1. Thereby, the second enlarged diameter portion 2
2 is also reduced in diameter and is brought into close contact with the branch tube 10.
