초록 ▼

A quick connect coupling for connecting a tube to a body having a stepped bore formed therethrough. The coupling includes a sleeve which is press fit in the bore. The inner surface of the sleeve has a cylindrical portion, a radially outwardly extending frusto-conical portion, and an internal shoulder defined therebetween. A collet is disposed within the sleeve having a boss portion which is slightly smaller than the inner diameter of the cylindrical portion of the sleeve. The boss portion supports and guides the collet for co-axial movement relative to the sleeve. The collet further includes an enlarged end portion having an external shoulder and a frusto-conical surface. The frusto-conical collet surface is disposed within the frusto-conical sleeve surface. The tube is inserted within the coupling within the collet. When it is attempted to move the tube out of the body, the frusto-conical collet surface engages the frusto-conical sleeve surface. Also, the external collet shoulder engages the internal sleeve shoulder. As a result, the collet (and the tube engaged thereby) are positively retained within the coupling and the body.

대표청구항 ▼

A coupling for connecting a body to a tube comprising: a bore formed in the body; a sleeve provided within said bore and immovable relative thereto, said sleeve including a first frusto-conical surface defining a radially outer end and a radially inner end, a second frusto-conical surface defining a radially inner end and a radially outer end, and a radially extending shoulder defined between the inner ends of said first and second frusto-conical surfaces; a collet disposed within said sleeve and including a plurality of fingers, each of said fingers including an enlarged end portion defined by a radially outwardly extending shoulder and a frusto-conical surface extending from a radially inner end at said shoulder to a radially outer end, said collet shoulders cooperating with said sleeve shoulder to retain said collet within said bore when said collet is attempted to be moved axially out from said bore; and means for connecting said collet to the tube to connect the tube to the body.
