維持し得る。By mounting the caulking ring together with the joint metal fitting at the time of molding the EF joint, the caulking of the joint metal fitting having an outer diameter larger than the inner diameter of the caulking ring can also be carried out, and there is a gap between the EF joint and the caulking ring. It is possible to obtain a predetermined adhesion force with a minimum amount of deformation, to suppress the strength reduction of the caulking ring to a minimum, and to endure the caulking ring with a uniform force to obtain high retaining strength. And, the strength can be maintained for a long time.

It is attached at the time of molding the joint (1), and the conductive wire (6) of the EF joint (1) (the conductive wire folded in two is coiled around a cylindrical surface and held in a sleeve shape) and the joint metal fitting (3). ) Together with the caulking ring (20) in the mold (insert), the caulking ring (20) is mounted together with the conductive wire (6) and the joint fitting (3), and
With the injection product or the injection screw, the molding material (thermoplastic resin) that has been melted by heat and fluidized in the injection cylinder is press-fitted into the mold which is tightly closed, thereby forming a resin product (4). A conductive wire (6) is embedded in the contact surface, and a small-diameter sleeve (3) of the joint fitting (3) is provided in the receiving port (12) opposite to the receiving port (5) of the resin product (4).
EF joint (1) in which the b) is integrally fitted and attached, and the caulking ring (20) is integrally fitted and attached to the outer periphery of the receiving port (12) in which the small diameter sleeve (3b) is integrally fitted and attached. Is molded.

と共に、漏れの発生を防止できる。Since the caulking ring is integrally attached to the outer circumference of the receiving opening of the EF joint for fitting the joint metal fitting,
Since the joint surface of the F-joint and the joint fitting are brought into close contact with each other and are made airtight, it is possible to prevent the leakage with high strength and prevent leakage from occurring.

実に維持できる。Further, by mounting the caulking ring together with the joint metal fitting during molding of the EF joint, the caulking of the joint metal fitting having an outer diameter larger than the inner diameter of the caulking ring can be carried out, and it can be applied to prevent any joint metal fitting from being pulled out. . Further, since there is no gap between the EF joint and the caulking ring, it is possible to obtain a predetermined adhesion force with a minimum amount of deformation, and it is possible to suppress the strength reduction of the caulking ring to a minimum. In addition, the endless caulking ring enables caulking with uniform force. By these, higher retaining strength can be obtained, and the strength can be reliably maintained for a long period of time.
