Abstract

The connector (1) has an axially slotted bushing (2), and fastening lugs (3, 3a) formed at the bushing ends. One of the fastening lugs has two recesses arranged at a distance to one another in an axial direction of the bushing. Another fastening lug has recesses for feed-through of detachable screwing units (6, 6a). An intermediate unit is arranged between the fastening lugs and the screwing units. The bushing has an opening (9) at an intersection area of the fastening lugs between the recesses.

Description

  • The The invention relates to a pipe connector with the features of Preamble of claim 1.
  • It's from the American patent US 2,227,551 out. In this patent a pipe connector for two pipes is described. The pipe connector consists essentially of an axially slotted sleeve, wherein a fastening tab is integrally formed on each sleeve end adjoining the slot. Sleeve and mounting straps are made in one piece. Each mounting tab has two holes axially spaced from each other. The holes in the mounting tabs are for receiving Verschraubungsmitteln, a screw and a nut, corresponding to each other. During assembly, a screw is inserted through two corresponding holes and from the other side a nut is screwed onto the thread of the screw. In order to achieve a uniform distribution of force on the mounting straps, pad blocks are provided, which can be arranged in each case between the screw head and mounting strap or nut and mounting strap. After the fastening tabs have been screwed together, the fastening straps form an axially aligned gap relative to each other, which is wider than the sleeve as far as the sleeve is located. Through this wedge-shaped gap formation, the force that is introduced when screwing into the sleeve is increased, since the fastening tabs are remote from the sleeve supported on each other.
  • There the pipes to be connected usually have manufacturing tolerances in their outer diameters, It may happen that the pipe connector is already firmly on the pipe with the larger diameter is mounted while the pipe connector to the second pipe, with the smaller outer diameter forms a gap. This can lead to leakage or vibration Cause problems, there under circumstances no exact positive connection between the pipe and the pipe connector is formed.
  • task the present invention is to show a pipe connector, even with outside diameter tolerances the pipes to be connected a tight pipe connection and a non-positive and positive Makes connection.
  • These The object is achieved by the feature in the characterizing part of the claim 1 solved.
  • by virtue of the opening according to the invention is in the transition area between the fastening tab and the sleeve reduces the rigidity, so that, when screwed a cheaper elastic and / or plastic adaptation of the pipe connector to the pipes to be connected arises. Thus, you can the two screwed connections of the pipe connector are individually tightened, d. H. be applied individually with a defined torque, so that each side of the pipe connector completely around the respective pipe to be connected hugs.
  • The Embodiment according to claim 2 is very easy to manufacture.
  • The Embodiment according to claim 3 represents the preferred size range the opening.
  • The Embodiment according to the claims 4 and 5 reinforced the effect of the invention.
  • The Embodiment according to claim 6 minimizes the lateral influence of the two screw connections with each other.
  • The Embodiment according to claim Again, 7 is a preferred size range for the opening.
  • With the embodiment according to the claims 8 and 9, a further improved tightness of the pipe connector is achieved.
  • in the The invention is based on a preferred embodiment closer in two figures explains:
  • 1 shows an exploded view of an inventively designed pipe connector;
  • 2 shows the top view of an assembled, shown three-dimensional pipe connector.
  • 1 in which for the same components as in 2 the same reference numerals apply, the plan view shows an exploded view of a pipe connector designed according to the invention 1 , The pipe connector 1 consists essentially of an axially slotted sleeve 2 , wherein on both sides of the slot each have a fastening tab 3 . 3a to the sleeve 2 is formed. In the present embodiment, the sleeve 2 and the fastening straps 3 . 3a made in one piece by the machining of a sheet metal.
  • The fastening straps 3 . 3a each have two axially spaced and mutually corresponding openings 4 . 4a and 5 . 5a on. The breakthroughs 4 . 4a . 5 . 5a are square in the present embodiment, for receiving Verschraubungselementen 6 , in the present example carriage bolts with a form-fitting in the openings 4 . 4a . 5 . 5a engaging square neck. The screwing elements are screwed 6 with associated screwing elements 6a , Nuts. So that the force introduction of the screwing over the attachment tabs 3 . 3a evenly on the sleeve 2 is transmitted, is between the Verschraubungselementen 6 and the fastening strap 3a an intermediate element 7 insertable, as well as between the screwing elements 6a and the fastening strap 3 one intermediate element each 7a , The intermediate elements 7 . 7a are in the present embodiment Einlegplatten, which are also the square openings 4 . 4a . 5 . 5a the fastening straps 3 . 3a exhibit. In other embodiments, it is also possible instead of the breakthroughs 4 . 4a and 5 . 5a in the form of square holes also use round holes. In this case, also conventional screws for screwing the pipe connector 1 can be used, but with simultaneous loss of positive engagement.
  • According to the invention, the pipe connector 1 in his sleeve 2 a first radial about 180 ° around the sleeve 2 extending and a second radially extending about 90 ° around the sleeve slot 9 on. The slot may extend in other embodiments to nearly 360 ° radially around the sleeve so that only a small, possibly only a few mm wide ridge remains in the sleeve. In the simplest case, instead of the slot, a hole at the transition between a fastening tab 3 . 3a and the sleeve 2 brought in. The opening preferably has a diameter or a clear width of between 1 and 10 mm. In the event that the opening 9 a slot extending radially around the sleeve has its width in the axial direction preferably between 0.1 and 10 mm. In a further embodiment variant, it is also possible with a slot as an opening 4 . 4a . 5 . 5a the fastening strap 3 . 3a between the breakthroughs 4 . 4a to share. To the tightness of the pipe connector 1 To improve again, there is a possibility between the sleeve 2 and the pipes to be installed another, slotted, resilient in outer diameter tube 10 to arrange. Next, between the tubes and the resilient tube 10 and / or between the resilient tube 10 and the sleeve 2 a sealing element can be provided. This may be a flexible flat gasket, a pipe gasket or a curable liquid gasket.
  • To the tightening torque of the pipe connector 1 to improve the pipes to be joined, form the fastening tabs 3 . 3a after its screwing a wedge-shaped gap 8th in the axial direction. This gap 8th , is close to the sleeve wider than sleeve away.
  • If two tubes of nominally equal diameter but with an outside diameter tolerance are to be connected to each other, the first tube will be inserted from one side into the tube connector 1 and the second pipe from the other side into the pipe connector 1 inserted. Subsequently, bolting elements 6 , the screws in the breakthroughs 4 . 4 , and 5 . 5a used, and the screwing element 6a , the nuts, tightened with such a large torque, that the sleeve 2 spans over the pipes to be connected. When applying an even larger torque on the screwing 6a , the fastening straps are supported 3 . 3a sleeve apart, whereby the clamping torque on the sleeve 2 is improved again. Assign the tubes to each other diameter tolerances, it can be achieved with an individual torque in the screw that the sleeve 2 around the pipe with the smaller diameter due to the invention staltung, the "softness", so far deform until it completely seals the pipes to be joined.
  • If necessary, between the fasteners 6 . 6a and the fastening straps 3 . 3a as in the embodiment intermediate elements 7 . 7a be provided. These are preferably rectangular and point to the openings 4 . 4a and 5 . 5a in the form and location of corresponding breakthroughs.
  • In order to improve both the gas-tightness and the structural dynamic properties of the pipe joint, as already shown above between the sleeve 2 and the pipes to be joined another, slotted and resilient in outer diameter pipe 10 to be ordered.
  • Due to the inventive design of the pipe connector 1 is a pipe connector in a simple and practically cost-neutral manner 1 which compensates for diameter tolerances of pipes to be connected while having improved gas tightness and mechanical strength.
