Definitions

  • Connecting sleeves are used to connect fluid-carrying components, e.g. containers or fluid lines (hoses, pipes, etc.) to one another.
  • the fluids can be gaseous or liquid.
  • Connecting sleeves generally have a first connecting section for connecting to a first fluid-carrying component and a second connecting section for connecting to a second fluid-carrying component.
  • such connecting sleeves can be designed in one or more parts and made of different materials, e.g. plastic or metallic materials.
  • different connecting sections can be provided, although the first and second connecting sections can of course also be different.
  • Connecting sleeves can, for example, be connected directly to the fluid-carrying components, but can also be connected indirectly, e.g. via plug connectors, to the fluid-carrying components.
  • a generic connecting sleeve for connecting to a connector is disclosed, for example, in WO 2022/155694 A1 under the name “mating connector”.
  • the disclosed connecting sleeve is made of a metallic material and designed as a formed sheet metal part.
  • an insertion section for insertion into the opening of the wall of the container is provided in the region of the first sleeve end, and wherein the connecting sleeve comprises a peripheral shoulder which delimits the insertion section in the direction of the second sleeve end, wherein the connecting sleeve is inserted with the insertion section into the opening of the wall of the thin-walled container until the peripheral shoulder rests against an outer surface of the wall and a crimping section provided on the insertion section is at least partially within the container and the crimping section is plastically deformed using a crimping tool so that the wall of the thin-walled container is clamped between the plastically deformed crimping section and the peripheral shoulder.
  • a seal is arranged between the wall and the peripheral shoulder before insertion, which is clamped between the wall and the peripheral shoulder during plastic deformation of the crimp section in order to create a seal between the wall and the peripheral shoulder.
  • a flat seal or a sealing compound can be used as a seal, for example. This creates a tight connection so that an undesirable leakage of a fluid in the container into the environment can be avoided.
  • a circumferential groove is provided on an annular end face of the circumferential shoulder facing the first sleeve end, and an O-ring is used as a seal, which is arranged in the circumferential groove, wherein a diameter of the O-ring is larger than a depth of the circumferential groove in the axial direction and wherein the O-ring is squeezed during plastic deformation of the crimping section until the annular end face rests against the outer surface of the wall.
  • a sealing material is applied to the outer peripheral surface of the insertion section, in particular between the crimp section and the peripheral shoulder, before insertion into the opening.
  • the insertion section is made of a sealing material at least in the area of the outer peripheral surface, in particular between the crimp section and the peripheral shoulder. This can achieve improved sealing.
  • the sealing material can, for example, comprise a liquid sealing material that hardens after connection.
  • the insertion section to have a type of rubberized outer peripheral surface or to generally be made of a preferably relatively soft material with a good sealing effect, e.g. from a suitable plastic such as silicone or from a relatively soft metal such as copper or a copper alloy.
  • a first crimping tool is used as the crimping tool, which has a plurality of jaws that can be moved in the radial direction, on each of which an engagement projection directed outwards in the radial direction is provided, wherein the first crimping tool is moved from the second sleeve end through the connecting sleeve into the interior of the container, then the jaws are moved outwards in the radial direction and the engagement projections are brought into contact with a sleeve end face that delimits the connecting sleeve at the first sleeve end.
  • a second crimping tool can be used as the crimping tool, which has a plurality of jaws that can be moved in the radial direction, on each of which a pressing section directed outwards in the radial direction is provided, wherein the second crimping tool is moved from the second sleeve end through the connecting sleeve in the direction of the first sleeve end until the pressing sections are in the area of the crimping section, wherein the jaws are moved outwards in the radial direction until the pressing sections rest against an inner circumferential surface of the crimping section and that by means of the pressing sections a second crimping force directed outwards in the radial direction is exerted on the inner circumferential surface of the crimping section, by means of which the crimping section is plastically deformed into a circumferential bead.
  • the shape and size of the circumferential bead can thus be influenced in a targeted manner via the shape of the pressing sections and the level of the second crimping force.
  • the second crimping force acting radially outward no or only a relatively low holding force is required to hold the connecting sleeve on the container during the crimping process.
  • the pressing sections each have a rounded pressing surface.
  • the plurality of jaws have at least four jaws, preferably at least six jaws. This allows a lower second crimping force to be generated per jaw.
  • Fig. 2 shows the thin-walled container and the connecting sleeve of the first embodiment at a second point in time during the method according to the invention
  • Fig. 3 shows the thin-walled container and the connecting sleeve of the first embodiment at a third point in time during the method according to the invention

  • Fig. 8 shows the thin-walled container and the connecting sleeve of the second embodiment at a fourth point in time during the method according to the invention
  • Fig. 9 shows a crimping tool of an advantageous embodiment in a perspective view.

  • the opening O can be circular and have a diameter that corresponds to the outer diameter of the insertion section 4 or is slightly larger.
  • the connecting sleeve 1 comprises a peripheral shoulder 5 which delimits the insertion section 4 in the direction of the second sleeve end 3.
  • the connecting sleeve 1 comprises a crimping section 6.
  • the crimping section 6 is designed to be plastically deformed by means of a suitable crimping tool WZ in order to form a circumferential bead 15, as will be described in more detail below.
  • the connecting sleeve 1 is formed in one piece.
  • the connecting sleeve 1 can be formed, for example, from a metallic material or from a suitable plastic. Since the connecting sleeve 1 is in one piece, the circumferential shoulder 5 and the insertion section 4 are thus formed from the same material.
  • the crimping section 6 is only indicated schematically.
  • the crimping section 6 can be created, for example, by a suitable material weakening of the insertion section 4.
  • the material weakening can be achieved, for example, by reducing the wall thickness in the area of the crimping section 6 compared to the remaining area of the insertion section 4.
  • the material weakening could alternatively or additionally also be achieved by providing a number of openings that completely or partially penetrate the insertion section 4 in the area of the crimping section 6 in the radial direction. For example, several such openings could be arranged distributed around the circumference in order to achieve the most uniform possible formation of a circumferential bead 15.
  • a seal 7 is also provided.
  • the seal 7 is designed here as a flat seal, in particular as a sealing ring.
  • the flat seal surrounds the insertion section 4 and rests against a preferably flat end face 8 of the circumferential shoulder 5, which faces the first sleeve end 2.
  • a suitable sealing compound could also be used instead of a flat seal.
  • a suitable sealing material could be applied to the outer peripheral surface of the insertion section 4, in particular in the area between the crimp section 6 and the peripheral shoulder 5, before insertion into the opening O. In the assembled state, the sealing material can immediately create a seal with the wall W.
  • the insertion section 4 could also be made of a sealing material at least in the area of the outer peripheral surface, in particular in the area between the crimp section 6 and the peripheral shoulder 5.
  • the outer peripheral surface could be rubberized or the entire insertion section 4 could be made of a suitable sealing material.
