Definitions

  • the invention relates to a plug connection for pipe and hose lines with an oblique seal according to the preamble of patent claim 1.
  • EP 0 750 152 B1 which is based on the same Applicant, describes a plug-in connection for the connection of pipe and hose lines, the description of which is to be included in full content of the disclosure of the present invention.
  • This specification discloses a sealing ring which has an approximately cylindrical shape. It seals with a cylindrical surface on an opposite cylindrical surface of the nozzle.
  • cylindrical sealing ring an enlarged length of the nozzle can be accepted.
  • the nozzle must be made correspondingly long long displacement path for the seal to the Reaching the detent position allows, as well as in addition a correspondingly cylindrical contact surface are provided for the sealing ring.
  • the invention is therefore the object of developing a connector of the type mentioned so that with shorter overall length of the nozzle and the plug lower Aufschub structure for the preparation of the locking connection are made possible.
  • the sealing ring is formed as an oblique sealing ring, which has a base leg directed in the axial direction, - which can be inserted into a U-shaped receiving space on the plug and further has at least one beveled at an angle to the plug ' te sealing lip, which is located on a slope of Locking shoulder of the neck sealingly applies.
  • a so-called oblique sealing ring is used, which has an axially extending, parallel base leg, with the oblique sealing ring ⁇ h 'also open in the insertion, approximately U-shaped profiled Groove is inserted and held on the plug.
  • This U-shaped groove thus forms the receiving space for the support of the base leg of the helical seal.
  • a significant saving in the length of the plug and associated nozzle is achieved by providing that the oblique seal with its sealing lip on the slope of the locking shoulder of the neck sealingly applies.
  • the oblique seal with its sealing lip on the slope of the locking shoulder of the neck sealingly applies requires no more investment in a long-trained, cylindrical sleeve part of the nozzle, but it is only the short - increasing in diameter - slope of the locking shoulder used as a bearing surface for the sealing lip of the helical seal.
  • the two parts, namely nozzle and connector to lead against each other and stuck together without already the oblique seal with its sealing lip comes into sealing engagement with the nozzle.
  • the insertion force required for this purpose is therefore much lower than in the prior art, where the sealing lip already represented a significant frictional resistance in the manufacture of the latching connection. This is avoided according to the invention.
  • the invention provides two different embodiments.
  • a first embodiment it is provided that the base leg is inserted positively and sealingly in this ' U-shaped profiled receiving space, resulting in a displacement of the air trapped in the receiving space. So that this air can be removed, a cannula is introduced according to the invention together with the sealing ring in the receiving space. The cannula causes the venting of the receiving space when the base leg of the oblique sealing ring is inserted into the receiving space while displacing the volume of air.
  • the invention is not limited to an oblique sealing ring with a single sealing lip. It may also be provided in a development of the invention that instead of a sealing lip two oppositely Asked sealing lips are present 1 , each of which create a sealing on the slope.
  • Figure 1 section through a connector according to the invention before reaching the locking position
  • Figure 2 section through a connector according to Figure 1 before reaching the
  • Figure 3 section through the connector of Figure 1 in the sealing and locking position
  • Figure 4 an enlarged partial section through the plug connection in the region of the oblique sealing ring during its assembly
  • Figure 5 The finished assembled oblique seal according to Figure 3 in his
  • FIG. 6 an embodiment of a modified embodiment compared to FIGS. 3 and 4
  • Figure 7 an opposite to the other two embodiments again modified embodiment of a helical seal.
  • the plug is connected to a hose as a material-separated part or whether the plug and the hose form a material integral part. In the latter case, the plug is molded on the hose, for example. In the position shown in FIG. 1, an approximately cylindrical connecting piece 1 is inserted into the insertion opening of a plug 7.
  • the nozzle 1 has a rear cylindrical cross section, in the lateral surface of a locking shoulder 2 is arranged.
  • the latching shoulder 2 is formed by a slope 4 rising in the insertion direction, which merges into a steeply formed latching surface 3.
  • the latching connection of the plug 7 is made with a detent spring 9, of which the two mutually parallel locking legs 10 are only partially shown in Figure 2.
  • the two locking legs 10 engage through openings 11 in the plug 7 therethrough. In the latched position, they put on the back of the locking surface 3 of the nozzle 1, whereby the connector is made.
  • FIG. 1 shows that for the production of the plug-in connection, first the socket 1 is inserted into the plug 7; wherein in the interior of the plug 7, an oblique sealing ring 18 is mounted, the sealing lip 20 of Figure 1 still receives no sealing engagement with the sleeve part 5.
  • the detent spring 9 will accumulate on the slope 4 in the plug movement.
  • the detent spring 9 is widened radially.
  • the insertion force which is used for inserting the nozzle 1 in the plug 7, is used to produce the latching connection, without having to overcome a frictional resistance at the sealing lip 20.
  • the short sealing path 27 results from the beginning of the slope in comparison to the position of the sealing lip.
  • the sealing lip 20 is therefore only half of the slope 4 slid up to then come with the bevels in sealing engagement.
  • FIG. 3 shows further details of the installation of the oblique sealing ring 18.
  • the oblique sealing ring 18 has a base leg 19 which is directed backwards in the direction of insertion (arrow direction 23) and which is received positively in an associated receiving space 17 on the plug 7.
  • the receiving space is formed by a cylindrical bearing surface 14 of the plug 7, which merges into a perpendicular thereto cranked annular groove 15, which in turn merges into a lower contact surface 16.
  • the two contact surfaces 14 and 16 are directed approximately parallel to each other. However, they can also be tapered at an angle to create a receiving space 17, which widens from the insertion back towards the rear.
  • the invention provides that a cannula 24 is inserted with a vent channel 25 with its front tip into the receiving space 17 and the air volume is vented via the vent passage 25 in the direction of arrow 26.
  • a cannula 24 of the base leg 19 of the helical seal 18 can be fully inserted into the receiving space 17 and sucks there.
  • the sealing lip 20 forms in the insertion direction, a slope 21, which provides the sealing engagement with the bevel 4 on the nozzle 1.
  • an incision 22 is arranged between the base leg 19 and the sealing lip 20 and extends over the entire circumferential length of the oblique sealing ring 18.
  • FIG. 4 shows the fully assembled position of the oblique sealing ring 18 when the cannula 24 has been removed in the direction of the arrow 26.
  • FIG. 5 shows a modified embodiment of an oblique sealing ring 18.
  • the oblique sealing ring 18 forms an air valve 28 on its side resting against the contact surface 14.
  • the air valve is formed by a valve lip 29 directed in the opposite direction in the insertion direction, which extends over the entire circumferential length of the oblique sealing ring 18 and has a recess 30 adjoining it. Behind the recess 30 an exemption 31 is arranged. Will thus pressed the base leg 19 of the helical seal in the receiving space 17, then the compressed air volume leads to a pressure increase in the receiving space and the compressed air volume flows under elastic deformation of the valve lip 29 on this valve lip 29 away in the direction of arrow 26 into the recess and then into the adjoining Exemption 31 to the outside.
  • FIG. 6 shows as a further embodiment that not only a single-winged sealing lip 20 can be used, but that a two-winged sealing lip 20, 20 'can be used on an oblique sealing ring 18'.
  • Such a double-leaf seal is suitable both for guiding a vacuum and an overpressure medium in a connector according to the invention.
