Definitions
- the invention relates to a plug connection for the connection of a pipe section to a connection piece or counterpart, in that the counterpart is pushed over the hose line and can be locked with the aid of a securing means.
- plug or coupling connections are used in motor vehicle construction for piping systems, for. B. suitable for sealing air ducts, charge air cooler lines and the like.
- EP 0 488 844 and EP 0 392 234 describe a plug-in connection which essentially consists of an inner sleeve onto which the hose is pushed and an outer sleeve pushed onto the outside of the hose, the two sleeves being connected to one another at one end.
- the inner sleeve is necessary to fix the hose, the pushed-on outer sleeve being connected to the inner sleeve by a press fit.
- a pipe socket which carries a resilient securing means, is pushed over the outer sleeve.
- DE 196 01 667 describes a plug-in connection without an inner sleeve, the outer sleeve being secured in position and attached to the hose without mechanical fastening means.
- the outer sleeve is vulcanized onto the hose or vulcanized into an associated recess in the area of the wall.
- EP 0 573 863 describes a hose connection, the end section of which is formed in one piece from the thermoplastic and a connection with the engagement element on the counterpart is achieved via a separate engagement element, the engagement elements performing movements when the components are locked and acting as a spring.
- the disadvantage here is the high assembly and disassembly effort.
- the invention is therefore based on the object of providing a plug connection which ensures the same good properties as the known plug connections with inner and / or outer sleeve, a connection with known standard ball couplings being possible without the assembly or disassembly being made more difficult.
- the object is further to develop the end piece of the hose so that the use of an outer sleeve is not necessary.
- the object is achieved in that the end piece of the tube is formed in one piece from the plastic tube in the form of a plastic part and is preferably produced in a blowing process.
- the tube can e.g. B. can also be produced by injection molding or by rotary sintering.
- the material must have sufficient temperature resistance and dimensional stability and the shape of the end piece must be adapted to the shape of the counterpart.
- the plastics known for such applications are suitable, provided they have the properties mentioned.
- the end piece (2) is produced directly with the tube (1) in the blowing process.
- An annular groove (4) for receiving a seal (10) is arranged on the upper edge of the end piece (2).
- the seal (10) is thus on the outside of the end piece (2) and the inside of the pipe socket (3) to be placed.
- a further annular groove (5) is provided for axially fixing a steel ring (6).
- the steel ring (6) with a round or rectangular cross section has at least two outwardly directed cranks (7) as a contact surface for the locking elements (13) present in the counterpart (3).
- the steel ring (6) is not a closed ring, but is opened at one point (8) for better assembly.
- the ends of the steel ring can be angled or overlapping one another.
- the open ends (8) of the steel ring (6) are connected in a material, non-positive or positive manner after insertion into the circumferential groove (5), it being intended to ensure that the steel ring (6 ) cannot come off the plastic part (2).
- the steel ring (6) is only fixed in the groove (5) and can rotate within the groove (5) on the pipe end piece (2).
- the steel ring (6) is primarily used to stiffen the pipe end piece made of one piece of material.
- the Steel- ring (6) has no spring or locking function.
- the locking function is effected by the locking spring (13) in the counterpart.
- the pipe end piece (2) has in the area of the offset (7) on the steel ring (6) exhibits (9) which are flush with the contour of the steel ring (6) and run obliquely into the contour from the steel ring (6) the catch spring (13) to facilitate the engagement.
- the steel ring (6) is widened such that the display (9) is formed from the steel ring (6).
- the pipe socket on the counterpart (3) also has an obliquely outwardly directed exhibition (11), which is interrupted by an opening (12).
- the detent spring (13) is arranged, which lies through the opening (12) with the associated spring legs of the detent spring (13) on the correspondingly assigned offset (7) of the steel ring (6).
- the tube (l) is secured in a known manner against being pulled off the counterpart (3) as long as the detent spring (13) is in the area of the opening.
- Figure 1 shows a representation of the pipe end (2) with the inserted steel ring (6).
- Figure 2 shows a sectional view of the hose coupling with the pipe end (2) and inserted steel ring (6) and the pushed-on counterpart (3) with the detent spring (13).
