摘要： A connector is provided for a small diameter pipe that has been formed to include an annular swelled part near the end of the pipe. The connector includes a body with a communication hole extending axially therethrough. A chamber extends axially into one end and joins the communication hole. A window is formed through portions of the connector body defining the chamber, and a pawl extends across the window. The pawl includes a central portion that projects into the chamber. The pawl is configured to engage the annular swelled part of the pipe for holding the pipe in the connector body. The connector further includes a releasing member rotatably mounted around the connector body in proximity to the pawl. Outer circumferential portions of the releasing member define a cam wall configured such that rotation of the releasing member into a selected rotational orientation will deflect the pawl outwardly to enable release of the pipe.

According to the present invention, a resin-uncovered portion of the metallic pipe provided for applying an end processing thereon is completely covered with a protective pipe made of a resin material so that the processed pipe can be connected with the mating member without spoiling its anti-chipping property and an anti-splashing property of the metallic pipe over the entire length thereof. With the exception of the end of the metallic pipe corresponding to the margin at least required for applying an end processing on the pipe, the pipe is covered with an extrusion-moldable thick film-like resin and is connected with a mating member by means of a clamp nut assembled to the pipe end so as to be screw-fitted with the mating member. The connecting structure according to this invention features that one end of a resin pipe is fitted about the above-described resin coated layer on the metallic pipe while the other end of the resin pipe is inserted into, or fitted about, the clamp nut and the resin pipe is fixed to the clamp nut at least at a single portion thereof.

摘要： A small-diameter resin tube connecting structure used as a small-diameter tube connector is provided. The connector comprises: a main body including therein a small-diameter chamber continuous with a communication hole defined by the connecting cylindrical wall at the top end of the main body and a large-diameter chamber formed behind the small-diameter chamber; and a socket having repulsive walls each in the form of a pawl wall and formed integral with, or separately from, the outer periphery of the connector main body whereby the repulsive walls of the socket are brought into engagement with an annular bulged wall of the target resin tube. Further, a thin-wall metallic tube having an annular bulged wall is inserted into at least the connecting end of the resin tube with the metallic tube serving as a reinforcing member for the resin tube. The resin tube may have the annular bulged wall together with the metallic tube by press-working the inserted metallic tube in the axial direction. The connector of the present invention can securely maintain the connection of the target small-diameter tube with the connector for a prolonged period of time, increase the resistance against the draw-out force and manufacture easily and in a simple manner without enlarging the size thereof.

摘要： An improved method of making a cross joint between different size pipes is provided. A punch, die and a pressing machine are prepared. The punch includes a center rest for receiving a small pipe, a curved slot and a curved surface for transforming an end of the small pipe. Under the actuation of the pressing machine, the end of the small pipe is transformed into an arcuate configuration which is identical with the inside curvature of a large pipe. Simultaneously, a curved bead is formed on the small pipe remaining circumferentially equal distances from the resultant arcuate edge of the small pipe. This distance is substantially the same as the wall thickness of the large pipe. Utilizing the arcuate edge and the curved bead, the small pipe and the large pipe are welded or brazed together, resulting in a cross joint having no protrusion into the large pipe space.
