DETAILS BOM direction relative to the internal protrusions, and the sleeve is made with an internal locking groove, interacting with snap-on external projections of the petals of the collet. The magnitude of the elastic deformation and the axial component at a known modulus of elasticity of the collet material is determined by the geometry of the BHCTynqB collet, the geometry of the right & points of the second tubular part, and the dimensions of the contacting elements of the joint. The implementation of the sleeve with the internal groove, in which the external protrusions of the collet snap into place, ensures simple fitment of its position on the collet. The drawing shows the proposed device, a longitudinal section. The tubing parts contain quick disconnects including tubular parts 1 and 2 (outer conductors of coaxial lines), with tubular part 1 provided with a collet 3 with inner protrusions 4 that snap into the groove 5 of the tubing 2. Bushing 6 is mounted for axial movement of the sleeve 6 , At the end of the collet 3, external projections 7 are made, which are axially displaced relative to the internal projections 4 to the distance f. . The sleeve b is made with an internal groove 8, into which the external projections 7 of the collet 3 snap into place. In addition, the coaxial lines contain internal conductors: the socket and the pin 10, as well as the dielectric supports 11 and. 12, A rubber gasket 13 is applied between the tubular parts for sealing. The deformed petals of the collet 3 are guided by the inner projections 4 into the wall 14 of the groove 5 of the outer conductor 2. In this case, the force P applied to the wall 14 from the elastic deformation of the petals of the collet due to the selected geometry of the projections 4 and the wall 14 of the groove 5 expands to the radial component C and axial Q, creating prnksim ends of the outer conductors 1 and 2 in the plane 15. The possibility of arbitrary axial displacement of the sleeve 6 from mechanical effects during connection operation is excluded by fixing its position on the collet 3 by snapping it the protrusions 7 of the collet 3 into the inner groove 8 of the sleeve 6. The force that must be applied to shift the fixed b in the axial direction is determined by the amount of elastic deformation of the petals of the collet 3, the geometry of its outer projections 7 and the inner groove 8. For connecting the outer conductors of the coaxial lines you need to move the sleeve 6 in the axial direction so that from under it were visible external protrusions 7 of the collet 3. After that, the coaxial lines are joined, while the pin 10 enters the socket 9, the internal protrusions 4 latches ive in groove 5, bushing; The cable bar slides onto the collet 3 until the external projections 7 snap into the groove 8. To disconnect the coaxial sleeve b, move it axially so that the external projections 7 are visible from under it, and the coaxial lines are separated. This embodiment of the quick coupling of the tubular parts makes it possible to increase the reliability of the joint by creating axial contact pressure of the connected tubular parts, which makes it possible to expand the field of application of the compound, for example, for VHF -. technology. It should be noted that the magnitude of the contact pressure and its repeatability do not depend on the actions of the operator, since they are determined only by the structural elements of the compound and the properties of the materials used. In addition, the use of elastic deformation of the collet tabs not only to create contact axial pressure, but also to fix the sleeve on the collet when connecting tubular parts, simplifies the design of the connection, eliminating the cylindrical compression spring and collar on the tubular part with the collet. The formula of the invention is a quick-release connection of tubular parts, one of which is made with an external annular groove, and the end of the other is a collet with spring petals having internal projections snapping into the groove of the first part, and contains a sleeve mounted on the collet with the possibility of axial movement, This means that, in order to increase reliability by creating axial contact pressure of the parts to be connected, the collet was also made with 5727S35 also with external protrusions at the end. the petals are axially displaced relative to the internal projections, and the sleeve is made with an internal locking groove that interacts with snap-fit, external projections of the petals of the collet.
