Of the The invention is therefore based on the object, a device according to the preamble of claim 1, a universal screw - in particular a cable / hose / pipe quick connector for the Building and plant system technology - to create.

These The object is achieved by the characterizing Features of claim 1 solved; to advantageous embodiments take the dependent claims.

aim is the construction of a universal screw - especially a cable / hose / pipe quick connector for the building and plant system technology - especially for cables, Connectors, corrugated hoses / tubes, spiral hoses / tubes, Smooth tubes / tubes, braided / fabric tubes / tubes, made of plastic and / or metal, with / without reinforcement, with / without Strain relief, with / without shielding, both of the cable and of the hose / tube.

• – einem Grundkörper, wie ein Doppelnippel mit Schlüsselansatz und einer Ringnut und/oder einem schlauchseitigen Innengewinde
• – einem Klammerkorb mit Schlauchaufnahmedorn, beide fest mit dem Grundkörper verbunden
• – einer Klemmutter, die als Überwurfmutter auf dem Grundkörper verschraubt ist und auf die Klammern des Klammerkorbs wirkt.

A first solution to this problem relates to the connection of an elastic tube with a smooth surface. The universal screw connection is constructed in one piece and consists of the captive parts

• - A basic body, such as a double nipple with key approach and an annular groove and / or a hose-side internal thread
• - A staple basket with hose receiving mandrel, both firmly connected to the body
• - A clamping nut, which is bolted as a union nut on the body and acts on the brackets of the staple basket.

• – sie einstückig aufgebaut ist
• – keine Einzelteile erst mit dem Schlauch in Verbindung gebracht und
• – die Teile nicht lage- und verarbeitungsgerecht aufgebracht werden müssen.

The special feature of this quick connector is that

• - It is constructed in one piece
• - no items first associated with the hose and
• - The parts do not have to be applied correctly and in accordance with the processing.

Farther The assembly of this fitting is opposite to the standard hose / pipe fitting. The hose is passed over the hose receiving mandrel of the staple basket applied to its stop; then that will be on the main body mounted clamping nut screwed towards hose and pushes with her inner cone the brackets of the staple basket against the Hose and the mandrel. The elastic hose with smoother Surface is mounted so tight.

In spite of the standard hose / pipe fitting opposite mounting direction the base body does not build with clamping nut and staple basket higher than in the known hose fittings. Preferably the nut is frusto-conical in shape for reception of the staple basket pronounced.

advantages arise in such a way that the clamping nut / the pressure ring is not prior to assembly in the correct position and in the correct order the hose / tube must be slipped. Farther does not have the operation 'hose / tube sleeve assemble ', but the hose receiving mandrel is already integral part of the staple basket or the basic body.

The Holding power is provided by clamp nut, staple basket and Hose receiving mandrel is sufficient; the connection quick connector - hose is solvable by screwing back the clamping nut. As materials for parts production come according to requirement and application of plastics, metals and / or precious metals to Application.

Preferably, the staple basket has on its bottom plate a projecting projection which enters or snaps into the annular groove / undercut of the main body with the aim of a solid Seat of the same. When using plastic materials, it is also conceivable to glue the staple basket if it has not already been prepared by injection molding. The connection between the staple basket and the tube / tube holder is also fixed or detachable, in order to adapt geometrically different tubes / tubes if necessary. A further advantageous embodiment results from threaded connections in the bottom area of staple basket and mandrel and body when the staple basket and / or the hose / pipe receiving mandrel are designed adaptable for changing hose / pipe insert.

one further advantageous embodiment according to, is the thread of body and clamping nut in their Work area steeper designed so that already by a simple relative rotation a closure with hose / pipe clamp is reached. Also, a clamping by briefly turning the clamping nut against the body with final locking the clamping nut given the user the haptic signal of the proper closure mediated.

In Another preferred application may be parallel ribbed corrugated tubing be mounted with the quick connector - possibly without Hose / pipe receiving mandrel - but without a tightness to get at the connection point.

Next a quick-fitting on the hose side, is first also a screw connection with external thread for the housing or wall mounting provided. In a further advantageous embodiment of the inventive novelty occurs in place of the external thread a connector technology - preferably for thin walls.

The screwing must be both in this discipline have required holding forces, as well as a tightness offer the degree of protection required in the intended application enough.

Of the Hose receiving mandrel serves to form a counterforce when used soft hoses, o. Ä., To sufficient tensile forces obtained from the pressure force of the brackets of the staple basket result. But comes the quick-fitting with staple basket and clamping nut for example as a cable or pipe fitting used, the power transmission must be directly on the plastic cable sheath or the pipe is made; the mandrel deleted.

in the Case of required surface or separation protection By way of example cable or pipe, affects in the axial direction slotted mandrel - the hollow cylinder of the mandrel becomes a single, interconnected finger in the floor area slotted - beneficial to the application; the slotted one Mandrel protects and separates on the one hand the cylindrical Surface of cable or pipe and transmits However, the necessary retention forces arealily his fingers.

According to the further advantageous embodiment of the inventive novelty the clamp basket with hose mandrel is supplemented by a sealing ring. Sealing rings made of elastomer or silicone plastics of specific hardness are known and are used in the industry z. B. as a cable seal used. They can be dependent on opening and / or Cable diameter to be adjusted in strength, It is available as a cable multiple seal and as a special seal for different cable applications, such as flat cables; however, their use always requires smooth surfaces.

According to the The present invention is intended to allow a variety of hose types be. While the corrugated hose / pipe still has an axial and radially symmetric surface, that of the brackets the staple basket still held, but not by the screw can be written more, there are a large number of Hoses with unsymmetrical surfaces, such as z. B. the spiral tubes - from different Material layers constructed, inside and / or outside by coated or uncoated plastic cores or metal wires Reinforced or braided or fabric hoses with different coarse mesh / fabric made of textile, plastic or metal, surface-coated and -uncoated, the both inside and outside smooth or not smooth surfaces can have.

In order to improve the inventive novelty of these types of hoses, a hollow cone-shaped sealing ring is proposed as a staple basket seal, consisting of viscoelastic (VE) foam with memory properties, also known as memory or support foam. The sealing ring plastic to be used is around a mold-laying foam, a deformable elastomer, which retains the embossed or abandoned outer shape for a long time. In addition, these VE foams are stabilized by additives such as protection against moisture by treatment with polyurethane (PU) spray elastomer.

at Use of the sealing ring thus produced in the staple basket of the quick connector there is the advantage, even with uneven cables to be fastened, Hoses and pipes - such as spiral, fabric or tube Braided hoses or mixed forms - not only a sufficient holding / pulling force but also a required tightness to be able to guarantee.

has the cable goods to be laid or the protective hose over an electrically conductive metal mesh in the outer Enclosure - for example, for the purpose of EMC / ESD protection - which consistently be connected with screw and wall / housing must, the use of the metallic quick connector is advantageous out, in which the grounding braid pulled over the sealing ring and with the staple basket and the inner cone of the clamping nut the required electrical connection to the wall / housing manufactures.

The picture shows a screw connection with closed staple basket 3 and locked hose. The wire-reinforced spiral hose is strongly asymmetrical; the position of the sealing ring in the staple basket as well as its sealing property on the wire-reinforced tube are clearly visible.

5 shows - how 2 for the smooth hose - a quick screw connection according to the invention 1 , but with sealing ring 5 in side view and axial section, a) with the staple basket open 3 and unlocked parallel ribbed corrugated hose / tube 72 and b) with the staple basket closed and the corrugated tube locked. The mechanical properties of the quick-action fitting correspond to those described above; The applied to the / the corrugated tube / pipe sealing ring contributes to the strain relief by applying holding / pulling force and seals the / the hose / pipe against the screw. The viscoelastic (VE) foam with memory property nestles in the wave troughs of the corrugated hose / tube and closes - as with the wire-reinforced spiral hose 73 - this tight. The connection screw connection - hose / pipe can be released by turning back the clamping nut.

With 6 becomes a producer kit for the universal quick-connect fitting 1 presented, which is composed as follows. Under a) are the different cables, hoses and pipes 7 presented, including a connector 76 . 78 , followed by b) connecting and connecting elements, such as various tube adapters 4 ; under c) ... f) follows the one-piece universal quick-fitting according to the invention, as detailed above, and under g) in the simplest case, a fastening nut 83 or various adapters 8th as an accessory for the system structure, such as EMC / ESD connection 81 , Swivel / elbows 82 and membrane housing ventilation 84 , The equipment of the screw connection kit is reproduced here by way of example in the form of a basic equipment; An assortment supplement is always available.

The achievable with the present invention consist in particular in that by means of a partially reduced, only one piece, simply constructed and produced universal quick-release from reaching forces for holding and sealing cable / hose / pipe assemblies can be applied protection class and the pick / remove mechanism is simple, self-explanatory and without a 'third hand'.

advantageous Further developments of the invention are the subject of the subclaims; the numerous possibilities and advantages of the design of the Invention are reflected in the number of property rights claims contrary.
