Definitions
- the invention relates to an insert piece for insertion into a quick connector device for fluid lines, the insert piece comprising a hollow cylindrical base body, the hollow cylindrical base body extending between a front annular surface and a rear annular surface along a cylinder axis and a through opening extending along the cylinder axis as well has an outer jacket surface for arrangement on an inner wall of a quick connector device, according to the preamble of claim 1.
- the quick connector devices have pipe sections into which the fluid lines are inserted and fastened.
- Welding rings are used in the quick connector devices to connect the introduced fluid line to the quick connector.
- the welding ring is heated and partially or completely melted.
- the material of the Weld ring adheres to the fluid line and an inner wall of the quick connector device. After cooling, the material solidifies and connects the fluid line with the quick connector device.
- the welding ring is inserted into the quick connector device prior to the insertion of the fluid line.
- the welding ring has an outer diameter that is minimally larger than the inner diameter of the quick connector device. This has the effect that the welding ring rests against an inner wall of the quick connector device.
- the inner wall can have a bead or groove in which the welding ring is arranged in order to fix its position on the inner wall.
- the fluid line is guided through the welding ring and has an outer diameter that matches an inner diameter of the welding ring.
- the object of the invention is therefore to provide an improved device that avoids damage to the fluid line and / or the quick connector device.
- the invention provides an insert for insertion into a quick connector device for fluid lines, the insert comprising a hollow cylindrical base body, where the hollow cylindrical base body extends between a front annular surface and a rear annular surface along a cylinder axis and one extending along the cylinder axis Through opening and an outer jacket surface for arrangement on an inner wall of a quick connector device, the invention providing that the through opening has a through section which widens in the direction of the front of its annular surface.
- the invention provides an insert piece which, by means of the passage section at the passage opening which widens in front of its annular surface, has a surface inclined with respect to the outer jacket surface.
- the through opening is limited by an inner jacket surface of the hollow cylindrical base body.
- the outer jacket surface can further be formed parallel to the cylinder axis.
- Next can the front and be aligned behind the ring surface perpendicular to the cylinder axis.
- the insert piece can be arranged on an inner wall of a quick connector device by means of the outer jacket surface, the front annular surface being directed towards an inlet opening of the quick connector device. In other words, the outer jacket surface rests against the inner wall of the quick connector device after the insert has been properly inserted into the quick connector device.
- the passage section When the outer jacket surface rests against the inner wall of the quick connector device, the passage section thus also provides a ge inclined surface with respect to the inner wall.
- the fluid line passes the front annular surface and then first strikes the insert piece at the through section. Due to the widening shape of the passage section, the force which is transmitted from the fluid line through the contact to the insert piece can be divided into a component oriented parallel to the inner wall and a component oriented perpendicular to the inner wall. Part of the force transmitted from the fluid line to the insert piece thus acts perpendicularly on the inner wall and presses the insert piece against the inner wall.
- the insert piece can be an insert ring for quick connector devices for fluid lines.
- the passage section has a taper starting from the front annular surface, so that the fluid line is guided through the inclined surfaces of the passage section into the passage opening. Furthermore, due to the passage section, a longitudinal axis of the fluid line can have an angle of up to 5 ° with respect to the cylinder axis, without the introduction of the fluid line into the passage opening being made difficult or blocked. The introduction of fluid lines in quick connector devices that have the A set piece is facilitated.
- the passage section can also have a round edge on the front annular surface.
- the front annular surface and the surface of the hollow cylindrical base body delimiting the passage section thus merge into one another.
- the rate of expansion of the passage section increases at the round edge as the distance from the front ring surface decreases.
- a fluid line does not meet a sharp edge or the front ring surface arranged perpendicular to the cylinder axis, but rather the round edge.
- the round edge has the effect that a force transmitted by the introduced fluid line is partially directed perpendicular to the inner wall of the quick connector device.
- the round edge effects an improved conduction of force in the insert itself. That is, if a fluid line transmits a force behind the round edge on the passage section, the round edge has fewer stresses than a sharp edge. The round edge thus further reduces the shear forces on the insert.
- the hollow cylindrical base body can have a bevel, which extends annularly around the passage section and delimits the passage section on the hollow cylindrical base body in a radial direction.
- the round edge can connect the front ring surface with the bevel.
- the bevel can be part of the inner jacket surface on the hollow cylindrical base body and defines the passage section.
- a bevel can be introduced into a workpiece afterwards without great effort or, in the case of extruded objects, it can already be provided with the shape for the workpiece to be produced. This makes the production of the insert easier tert.
- the insert piece can further comprise a material that is reinforced with fibers.
- the fibers can comprise glass fibers.
- the fibers cause external forces to be optimally distributed on the insert within the insert. Furthermore, the fibers can be designed in such a way that the proportion of the forces acting on the passage section of the insert that is directed onto the inner wall of the quick connector device is increased.
- the material can have a fiber content between 0% and 70%, preferably between 0% and 50%. With the proportion of fibers in the material, the proportion of forces can be set that is directed from the insert piece perpendicular to the inner wall. In this way, the force components can be set which cause tensions in the insert or on the quick connector device. An optimal distribution of the stresses can thus be selected, so that the risk of damage is further reduced.
- the ring surfaces can have at least an inside diameter between 13 mm and 15 mm, preferably 14 mm.
- an insert piece for fluid lines with a nominal width of 14 mm can be provided.
- Another aspect of the invention relates to a system for connecting fluid lines, the system having an insert according to the preceding description and a quick connector device for fluid lines, the quick connector device having an inlet opening and an inner wall extending from the inlet opening extends into the quick connector device, wherein the insert piece is arranged with the outer jacket surface on the inner wall in, wherein the front annular surface is directed towards the inlet opening.
- the system can have a fluid line with an end piece, the end piece having an outer diameter, the amount of which is between a largest diameter at the fürgangsab and a smallest diameter of the through opening.
- the outer diameter can thus be guided through the passage section.
- the fluid line is introduced with the end piece from the side of the insert into the fürgangsöff voltage on which the front annular surface is arranged.
- the passage section tapers and guides the end piece in the passage opening. Since the end piece has a larger outer diameter than the through opening at its smallest diameter, when the fluid line is passed through the through opening, a large amount of friction occurs at this position, with the materials of the fluid line and the insert being able to deform easily elastically or also plastically.
- the Materials can include plastics.
- the nominal diameter of the fluid line can be between 1 mm and 30 mm, preferably 14 mm.
- the fluid line and the quick connector device can be connected to one another at an angle between 0 ° and 10 °, preferably between 0 ° and 5 °.
- the fluid line can thus be inserted into the quick connector device at an angle and connected to the quick connector device at this angle. This simplifies the connection of fluid lines with the quick connector device.

- the quick connector device 30 has a chamber 38 which includes an inlet opening 32 through which the insert 20 and the fluid line 40 can be introduced into the chamber 38 of the quick connector device 30.
- the chamber 38 is delimited by an inner wall 34 of the quick connector device 30, the inner wall 34 being shaped like an inside surface of a hollow cylinder.
- a bead 36 is also arranged on the inner wall 34 and is designed to receive an insert 20. From the input opening 32, a seal 39 in the form of an O-ring is arranged behind the bead 36.
- the insert 20 is arranged in the bead 36.
- the insert 20 comprises a hollow cylinder base body 21, d. H. the insert 20 has the shape of a ring.

- the hollow cylindrical base body 21 further comprises an outer jacket surface 22 for arranging on an inner wall of a quick connector device.
- the outer lateral surface 22 is aligned parallel to the cylinder axis 29.
- the outer jacket surface 22 is arranged on the inner wall 34 of the quick connector device 30.
- the outer jacket surface 22 has a diameter that is minimally larger than a diameter defined by the inner wall 34 of the quick connector device 30.
- the ring surfaces 24, 25 have the same outer diameter as the outer jacket surface. As a result, the entire jacket surface 22 is pressed against the inner wall 34.
- the outer jacket surface 22 is at least partially arranged in the bead 36.
- the ring opening of the hollow cylindrical base body 21 is formed by a through opening 26 which extends along the cylinder axis 29.
- An inner jacket surface 43 of the hollow cylindrical base body 21 delimits the through opening 26 in the radial direction starting from the cylinder axis 29.
- the through opening 26 extends through the entire hollow cylindrical base body 21 and connects the ring opening of the front Ringflä surface 24 with the ring opening of the rear ring surface 25.
- the ring surfaces 24, 25 have in this example at least an inner diameter between 13 mm and 15 mm, preferably of 14 mm.
- the through opening 26 has a through section 27 which tapers starting from the front annular surface 24. Conversely, the fürgangsab section 27 expands in the direction of the front annular surface 24.
- the bevel 23 also converges conically from the front annular surface 24 to the section of the through opening 26 which is arranged outside the through section 27.
- the hollow-cylindrical base body includes a round edge 28.
- the round edge 28 connects the bevel 23 to the front annular surface 24. That is, the area between the bevel 23 and the front annular surface 24 is free of sharp edges.
- the fluid line 40 has an end piece 42 which, in FIG. 1 a, is arranged with an upper surface of the fluid line 40 on the bevel 23.
- 1a shows the introduction of the fluid line 40 into the quick connector device 30.
- the bevel 23 guides the fluid line 40 by means of the end piece 42 through the passage section 27 into the passage opening 26.
- the through section 27 has the effect that the fluid line 40 can have an angle to the quick connector device 30 when it is inserted.
- the fluid line 40 and the quick connector device 30 can be connected to one another at this angle due to the play that the passage section 27 allows because of its expansion to the front annular surface 24.
- the angle can be between 0 ° and 10 °, preferably between 0 ° and 5 °.
- the fluid line 40 Upon contact with the insert 20, the fluid line 40 transmits a force to the insert 20. This is shown in Figure 1b.
- the arrows point to the contact surfaces between the end piece 42 and the insert piece 20.
- the contact takes place between the fluid line 40 and the insert 20 on the round edge 28.
- the force that is carried by the fluid line 40 is directed along the arrows. This force presses the outer jacket surface 22 of the insert 20 at an angle to the inner wall 34 of the quick connector device 30.
- the force has a portion that is perpendicular to the inner wall 34, and a portion that is parallel to the cylinder axis 29 or Inner wall 34 is directed.
- the chamfer 23 has an effect analogous to that of the round edge 28.
- the chamfer 23 likewise directs part of the force transmitted by the fluid line 40 via the outer jacket surface 22 perpendicularly onto the inner wall 34.
- At least part of the force transmitted by the fluid line 40 is transmitted perpendicularly to the inner wall 34 through the bevel 23 or through the round edge 28, so that not all of the force acts parallel to the cylinder axis 29 or inner wall 34.
- the reduction in the parallel proportion of the force has the effect that a shear effect on the insert 20 is reduced. This has the consequence that the risk of breakage of the insert 20 is reduced. Since the insert 20 is held in a bead 31 on the inner wall 34, the edge of the bead 31 is also prevented from breaking due to a force transmitted from the fluid line 40 via the insert 20 to the edge of the sock 31.
- the insert 20 according to FIG. 2 a has a material that has fibers 33.
- the fibers 33 can be glass fibers.
- the fibers 33 are arranged in the material of the insert 20 that forces which act on the bevel 23 are at least partially transmitted in the direction of the outer circumferential surface 22. That is, when the insert 20 is arranged in the quick connector device 30, a larger part of the force acting on the bevel 23 is transmitted via the outer jacket surface 22 to the inner wall 34 than in the case if the material of the insert 20 did not include fibers 33.
- the material can be a plastic.
- the insert 20 can thus consist of a fiber-reinforced plastic material.
- the material can have a fiber content between 0% and 70%, preferably between 0% and 50%. The higher the fiber content of the fibers 33 in the material, the more force is transmitted perpendicular to the outer jacket surface 22. Conversely, the fewer fibers 33 the material has, the less force is transmitted perpendicular to the outer jacket surface 22.
- the fluid line 40 is designed in such a way that its outer diameter 44 has an amount which lies between the largest diameter 37 on the passage section 27 and a small diameter 35 of the passage opening 26.
- the largest diameter 37 and the smallest diameter 35 are shown in FIG. 2b.
- the nominal width of the fluid line 40 can be between 1 mm and 30 mm, preferably 14 mm.
- the fluid line 40 can be received by the through section 27 and guided into the through opening 26 who the.
- the fluid line 40 is moved along the cylinder axis with increased force due to the smaller smallest diameter 35 of the through-opening 26 in order to overcome the friction between the fluid line 40 and the walls of the through-opening 26 and the fluid line 40 and / or the Insert 20 easy to deform.
- the friction between the walls of the through opening 26 and the fluid line 40 also has the effect that the fluid line 40 is held in the insert piece 20 by means of frictional engagement in the quick connector device 30. It is not necessary to weld the fluid line 40 to the quick connector device 30.
- a cross section of a further embodiment of the insert 10 is Darge provides.
- the outer jacket surface 22 of the insert piece 10 has a groove 31 running around the cylinder axis 29.
- the channel 31 can receive a bead 41 shaped to match the channel 31, which is arranged on the bead 36 of the quick connector device 30 and extends along the inner wall 34 around the cylinder axis 29.
