TH34607B - Quick connector with resin tube - Google Patents

Abstract

DC60 quick connector with resin hose for fuel conveying which can connect resin pipes to the matching connector without problems, even if the resin tube is small in diameter, is provided. The quick connector 16 consists of a connector body 18 supplied with compression fitting 28, and fastener 20. The resin tube 10 has a compression wear section 10A, where the compression wear part 28 is highly tuned. suitable to wear compression The compression wear section 10A has been enlarged to the pipe diameter in advance, before the compression fitting. The compression fitting 28 is pressurized into the compression fitting 10A which has been enlarged, to make it non-retractable, thus achieving 16 quick connectors supplied as a piece. Same with resin hose 10 quick connector with resin hose for conveying fuel. which can connect resin pipes to the matching connector without problems, even if the resin tube is small in diameter, is provided.

Claims (5)

1.Fast connector splice structure And resin pipes 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 a general pipe shape as a whole. And there is a retaining part on the axial side of the body that is connected And has a compression fitting, which is compressed into the inside of the pipe. Resin from one end of that resin tube on 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. It is positioned closer to the far end of the matching pipe than the arranged pipe-side interface, thus forming an airtight 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-set pipe diameter before compression wear 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 fitted with a molded body mount interface. The body fixings are connected from the side, in the radial, so that they are fixed and fixed in the 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 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 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.
