TH70976A - Quick connector with resin tubing - Google Patents

Abstract

DC60 Quick coupler with resin tube for fuel transport, which can connect resin tube to its matching connector without any problem, even if the resin tube has a small diameter, is provided. The quick coupler 16 consists of a connector body 18 provided with a compression member 28, and a clamp 20. The resin tube 10 has a compression member 10A wherein the compression member 28 is properly adjusted for compression. The compression member 10A has been pre-enlarged by the diameter of the tube, prior to compression, the compression member 28 is pressed into the compression member 10A which has been enlarged, so that it cannot be withdrawn, thus enabling the quick coupler 16 to be integrated with the resin tube 10. The quick coupler with resin tube for fuel transport, which can connect resin tube to its matching connector without any problem, even if the resin tube has a small diameter, is provided. The quick coupler 16 comprises a connector body 18 provided with a compression member 28, and a fastener 20 . The resin tube 10 has a compression member 10A wherein the compression member 28 is suitably adjusted to be pressed into. The compression member 10A has been pre-enlarged to fit the diameter of the tube, prior to pressing. The compression member 28 is pressed into the compression member 10A, which has been enlarged, so that it will not be withdrawn, so that the quick coupler 16 provided can be integrated into the resin tube 10 .

Claims (5)

1.Fast connector splice structure And resin tubes for connecting resin conveying pipes Fuel and matching hoses comprising the connecting body, bracket and seal assembly; It is unique in that: a quick connector fitted with a resin hose is used for light vehicles; The body of the connector has an overall pipe shape. And there is a retaining part on the axial side of the body that is connected And there is a compression fitting, which is inserted into the inside of the pipe. Resin from one end of that resin tube to the other side of the connecting body. The holder is an assembly piece for being held in the holder fixing section. And has been done To coordinate with the convex or concave tubular interface that has been formed on the surface. Around the outer contour of the matching pipe and away from the axial insert end of that pipe for Fixation of matching tubes inserted in axial direction: sealing assemblies are installed within connector sequence at the inside of the body where Position it closer to the compression fitting than the placed retainer retainer. And sealing components It has been made in contact with the outer perimeter of the insertion end of the inserted matching tube. The access point is positioned closer to the far end of the matching tube rather than the arranged tube-side interface, thus forming an air-tight seal between the insertion end. And the inner surface of the body Connector; The resin tube is a small diameter tube with an internal diameter of not more than 5 mm. The compression wear of the resin tube which is compressed and the compression wear in it is expanded. Pre-pipe diameter before compression fitting And the compression wear parts have been put into Compression wear parts through enlarged tube diameter for single assembly in a pull-out condition. 2. The splice structure that holds the right in Clause 1 has the characteristics that the holder receives. Radial flexible deformation And consists of a fastening interface on the bracket side, which It can be assembled with a molded body mount interface. The body holder fixation is connected from the side, in the radial, so that it is fixed and fixed in Axial direction And an inner cam surface for flexible expansion of the bracket when a matching tube is inserted into the bracket and the outer cam surface for reducing the diameter of the bracket. The retainer is flexibly descended when it is inserted into at least one surface of the bracket fixing section. 3. The splice structure that holds the right in Clause 1 or 2 with the unique characteristics that The guard is assembled on a resin tube to cover the outer surface of the resin tube. 4. The splice structure that holds the right in Clause 1 or 2, with the characteristics that The resin tube has a multi-layer structure. And the inner layer of the resin tube has better gasoline resistance than the outer layer. 5. A method for the production of resin pipes equipped with a quick connector; The assembly methods include: one step of inserting the pre-heated diameter expansion spigot. With a contour corresponding to the shape of the inner surface of the supporter into the tube end. Resin in the axial direction; The insertion procedure of removing the enlarged dowel from the resin tube in such a way that Expansion tube shaped compression fitting is formed at the end of the resin tube; And the third step of the compression fitting of the quick connector into the compression fitting.
