Abstract

The present invention includes an apparatus for attaching hose and cable sets. This comprises at least one connecting body, the connecting body having a first end and a second end. A hose or cable set can be arranged at at least one of the two ends. In addition, the connecting body is set up and intended to be mounted, in particular releasably, on a fixing device. This is characterized in that at least one end of the connecting body has a closure by means of which the device can be attached to the fixing device.

Description

The present invention relates to a device for fastening hose and / or cable sets, as well as a system device according to the preambles of claims 1 and 10.

When assembling complex cable and hose sets, such as ventilation systems, various electrical and pneumatic, but also hydraulic connections must be made.

In the case of installation methods known from the prior art, cables and hoses without connectors were routed into the interior of the housing through, for example, tight PG screw connections and grommets, then wired in the ventilation housing in a time-consuming manner by the fitter and connected to consumers, sensors and actuators.

The requirement for impermeability and protection from outside air inside the housing was met by subsequent sealing using additional sealing compounds.

However, this led to a large installation effort of several hours with the additional risk that the electrical connectors are incorrectly connected by the fitter.

The present invention now sets itself the task of eliminating the above-mentioned problems and therefore offers a device for fastening hose and / or cable sets, in which assembly effort is reduced and an assembly error rate is reduced.

This can be achieved in particular by the fact that the above-mentioned plug connections are already produced by a pre-assembled device for fastening hose and cable sets.

According to at least one embodiment, the device for fastening hose and / or cable sets comprises at least one connection body, the connection body having a first end and a second end, with a hose or cable set being able to be arranged at least at one end.

In addition, the connecting body is set up and provided to be mounted on a fixing device, in particular detachably.

The fixing device can be such a device which is already available for fastening the device in a heating room or a sanitary room. The fixing device is therefore in particular a device different from the device claimed here and is not included in the device itself.

In particular, the fixing device can be a standardized fixing device with connecting elements manufactured according to the DIN standard. For example, the present fixing device therefore serves as a connecting element by means of which the device claimed here can be installed in a larger overall system, for example a heating system or some other technical system.

According to the invention, at least one end of the connecting body has a closure by means of which the device can be attached to a fixing device.

According to at least one embodiment of the device for fastening hose and / or cable sets claimed here, it comprises at least one connecting body, the connecting body having a first end and a second end, with a hose and / or cable set being able to be arranged on at least one end , and wherein the connection body is set up and intended to be mounted, in particular releasably, on a fixing device, and furthermore wherein at least one end of the connection body has a closure by means of which the device can be fastened to the fixing device.

According to at least one embodiment, the closure is formed from a direction, seen parallel to a cable feed-through direction, along a radial circumferential direction by at least two subsegments of different radii, a transition between the subsegments being made by at least one further radius or in a stepped manner.

The subsegments can therefore close the closure laterally to the outside. This can mean in particular that the subsegments, seen from the outside, are then not covered by another part of the closure. Viewed from the cable feed-through direction, the subsegments are completely visible from the outside in one embodiment.

A step, which represents a transition between the two subsegments in the circumferential direction, is thus preferably completely visible from the direction of the cable feed-through direction.
The cable feed-through direction is the direction within the connecting body along which one or more cables run through the connecting body.

Seen from this direction of the connecting body, the closure therefore has at least one, preferably flat, connecting surface and thus closing surface, which preferably has a step in the form of a step at the transition points in the circumferential direction on the individual subsegments. For example, the steps together with the subsegments form a bayonet-like closure together with a correspondingly constructed closure part of the fixing device.

It is conceivable that the individual subsegments have a constant radius in the radial direction.

Preferably only one of the two end surfaces of the connecting body is formed by the subsegments. For example, the other end surface is free of such a partially segment-like end surface. Such a surface can also be designed in the manner of a shaft, viewed from the direction of cable entry. The cables are therefore led out again in such a shaft. The shaft can be rectangular. An outer surface of the shaft can then have a maximum of four corners.

A dead weight of the connecting body is, for example, at most 0.7 kg.

As an alternative to this, however, it is conceivable that the subsegments, viewed in the radial direction, for example in the clockwise direction and the circumferential direction, have a radius that is increasing within the subsegment.

For example, it is conceivable that a subsegment begins with a predetermined radius and that this radius becomes larger, for example gradually, in a clockwise direction or in the reverse direction, that is to say linearly to the angle of rotation (in radial measure).

It is conceivable that the radius with which a subsegment begins in the circumferential direction is at most 20% smaller or larger than the radius with which a corresponding subsegment ends in the circumferential direction.

In addition, the, in particular step-like, transitions can also be designed in the form of saw teeth. The closure thus has a closing surface which is designed in the form of a sawtooth blade.

According to at least one embodiment, the closure is an integral part of the connecting body.

This can mean in particular that the closure is designed in one piece with the connecting body. The closure is therefore not arranged to be movable relative to the connecting body. In this respect, the entire device can be formed by one or more injection molding, injection molding or encapsulation steps, but the entire device is still in one piece.

According to at least one embodiment, the closure is a separate element mounted on one end of the connecting body. Therefore, instead of an element produced together with the connecting body as part of an injection molding, injection molding or casting process, such a closure is preferably an element arranged on the connecting body in a separate assembly step. The closure can be arranged on the connecting body such that it can rotate about the cable feed-through direction.

According to at least one embodiment, the closure is arranged to be rotatable relative to the connecting body about the cable feed-through direction.

For example, the closure is arranged on the connecting body by means of a rotary connection.

If the connection body has to be fastened to the fixing device, it can be fastened by rotating the closure and by subsequently engaging the closure on a corresponding connection device or fixing device.
According to at least one embodiment, the closure is arranged displaceably in a direction perpendicular to the cable feed-through direction.

Instead of or in addition to the above-mentioned rotary movement, the connection body can also be mounted on the fixing device by means of a corresponding displacement movement.

It is also conceivable that the closure is arranged on the connection body on the basis of a sliding connection. This enables, in particular, a particularly simple exchange of the closure in the event of possible wear of the same.

According to at least one embodiment, at least one sealing disk is arranged on the closure.

The sealing disk itself can be mechanically fixed, but preferably releasably arranged on the closure. It is also conceivable that the sealing washer is arranged around the closure so that it can rotate about the cable feed-through direction relative to the closure. As an alternative or in addition, however, the sealing washer can also be arranged such that it can be displaced relative to the closure in a direction perpendicular to the cable feed-through direction. The closure and the sealing disk can be formed with different materials.

The closure and the sealing disk have corresponding cable openings in order to be able to lead the cables and / or hoses passed through the connection body out of the connection body.

In a top view, the sealing disk preferably has the same dimensions and geometrical configurations as the closure surface of the closure. In this respect, the sealing washer can also have the same subsegments and the structure associated therewith. The sealing disk can thus also be constructed in the form of a sawtooth blade.

According to at least one embodiment, the sealing washer is applied to the closure in the course of an injection molding or potting step.

It is conceivable that the sealing washer is injection-molded with the closure as part of a 2K injection or potting step. This can mean that the sealing disk and the closure are formed in one piece, but preferably with different materials.

For example, the sealing washer is designed in the form of a flat seal. Flat gaskets belong to the static gaskets and are mainly installed in apparatus engineering or pipeline construction as a sealing element between two flanges.

A number of materials are available for flat gaskets for different applications (fluids, temperatures, pressures, chemical stress), such as: B. elastomers, pressed fiber, aramid fiber, carbon fiber, mineral fiber, metal, copper. Flexible metal seals are used when low screw forces are required. To prevent the seal from yielding under pressure, there is often either a groove in the flange or support rings are placed from the outside and inside. In order to create a tight barrier and not a large-area porous connection between the flange and seal, a higher pressure is generated locally, e.g. B. by a round or diamond-shaped seal between flat surfaces or cutting in the flange. Soft sealing material is often more permeable to diffusion than the support material, so that the supports are very precise and smooth and the sealing material can be very flat.

In particular, the flat seal can in turn be an encased flat seal. Sheathed flat gaskets can be formed from a core (any flat gasket material, fiber composite, PTFE) that is covered by a PTFE or metal shell (steel or corrosion-resistant nickel alloys). The sheathing protects the core against chemical attack from the medium to be sealed. The core itself has a supporting function that gives way due to the contact pressure.

According to at least one embodiment, the sealing disk is formed with a different material than the closure. This can mean that the material of the sealing washer and the material of the closure are not identical.

As is not finally shown below, the following 3D printing technologies can be used to manufacture the connection body, the closure and / or the sealing washer:

The FDM process (Fused Deposition Modeling)

Alternative names: Fused Filament Fabrication (FFF), Fused Layer Modeling (FLM)

The process refers to the application of layers (extrusion) of a material through a hot nozzle. The consumable material is in the form of a long wire (so-called filament) on a roll and is pushed into a print head by the conveyor unit, where it is melted down and applied to a print bed. The print head and / or print bed can be moved in 3 directions. In this way, layers of plastic can be applied to one another in stages.

The SLS process (selective laser sintering)

In contrast to the sintering process, in which substances are bonded together in powder form under the action of heat, in the SLS process this is done selectively by means of a laser (alternatively electron beam or infrared beam). So only a certain part of the powder is fused together.

For this purpose, a thin layer of powder is always applied to the printing bed by the coating unit. The laser (or other energy source) is now aimed precisely at individual points of the powder layer in order to form the first layer of the print data. The powder is melted or melted and then solidifies again by cooling it slightly. The unmelted powder remains around the sintered areas and serves as a support material. After a layer has solidified, the print bed lowers by a fraction of a millimeter. The coating unit now moves over the print bed and applies the next layer of powder. Then the second layer of the print data is sintered by the laser (or other energy source). This creates a three-dimensional object in layers.

Three-Dimensional Printing (3DP)

The 3DP process works very similarly to selective laser sintering, but instead of a directed energy source, a print head moves over the powder. This releases tiny droplets of binding agent onto the underlying powder layers, which are thus bonded together. Otherwise this procedure is the same as the SLS procedure.

Stereolithography (SLA)

Instead of a plastic wire or printing material in powder form, liquid resins, so-called photopolymers, are used in the stereolithography process. They are hardened in layers by UV radiation and thus create three-dimensional objects. To do this, the construction platform in the Harz Basin is gradually lowered. There are also variants (the so-called Polyjet process) without a whole basin with liquid resin. For this, an epoxy resin is applied drop by drop from a nozzle and cured immediately by a UV laser.

Laminated Object Manufacturing (LOM)

Alternative designation: Layer Laminated Manufacturing (LLM)

The process is based neither on chemical reactions nor on a thermal process. A separating tool (e.g. a knife or carbon dioxide laser) is used to cut a film or plate (e.g. paper) along the contour and glue it in layers. By lowering the construction platform, a layered object is created from glued, overlapping foils.

The present invention also relates to a system device for fastening hose and / or cable sets.

The system device described here has the same features and advantages as the device described above in reverse.

According to the invention, the system device therefore comprises a device as described in at least one of the exemplary embodiments described above, as well as at least one hose and / or cable set, which is arranged at at least one end of the connecting body.

Each hose and each cable of the hose or cable set is preferably passed completely through the connecting body, the closure and any sealing washer. Preferably, therefore, each hose and each cable of the hose or cable set is first introduced into the connecting body through the first end and guided out of the connecting body through the second end.

• Die 3 zeigt in einer schematisch perspektivischen Ansicht ein Ausführungsbeispiel einer hier beanspruchten Systemvorrichtung zur Befestigung von Schlauch- und Kabelsätzen.

In the following, the invention shown above is explained in more detail using an exemplary embodiment and the associated schematic perspective views.

• They show 1A-1D in schematic perspective views a first exemplary embodiment of a device claimed here for attaching hose or cable sets.
• The 2A and 2 B show various exemplary embodiments of a closure surface, seen from the cable lead-through direction, of a closure claimed according to the invention.
• The 3 shows in a schematic perspective view an embodiment of a system device claimed here for fastening hose and cable sets.

In the exemplary embodiments and in the figures, identical or identically acting components are each provided with the same reference symbols. The elements shown here are not to be regarded as true to scale. Rather, individual elements can be exaggerated for a better understanding.

In the 1A is a schematic perspective view of an embodiment of a device described here 100 for attaching hose or cable sets shown.
A connecting body can be seen 1 , the connecting body 1 a first ending 11 , as well as a second end 12 having at least one end 11 , 12 a hose or cable set 2 can be arranged (the hose and cable set 2 is particularly in the 3 shown).

In the 1A to 1D The embodiment shown is the closure 13 an integral part of the connector body 1 and thus also the basis of an injection, injection molding or casting process. Alternatively, however, is the closure 13 rotatable about a cable entry direction K1.

Can also be seen from the 1A to 1D each that two each through the ends 11 and 12 continuous cable routing within the connecting body 1 are formed through which one or more cables or hoses can be passed through.

It is particularly catchy from the perspective representations of the 1A to 1D depicted that the clasp 13 each along a circumferential direction by two sub-segment types T1 , T2 two different radii are formed (see 2A and 2 B) .

That means that there is a sub-segment T1 , T2 a constant radius along the circumferential direction with a sub-segment T1 , T2 of a larger or smaller radius and a respective transition between the two subsegments of the different radii takes place in the form of a step, that is, radially “suddenly”.

It can also be seen that the connecting body 1 has at least one continuous curvature along the cable feed-through direction K1, so that the cables or hoses, for example, perpendicular to one another in the connecting body 1 run out and then out again.

In addition, from the 1A to 1D recognizable that a corresponding sealing washer 15th on the outer surface of the closure 13 is upset. Also this sealing washer 15th naturally includes the corresponding openings for leading individual cables or hoses through the sealing washer 15th . In the present exemplary embodiment, the sealing washer is 15th as part of a 2K potting in one piece with both the closure 13 as well as with the connecting body 1 executed. For example are the clasp 13 and the connecting body 1 formed with the same material.

The 2A and 2 B show the closing surface of the closure along the cable feed-through direction K1 that is also along a direction L1 13 from which the above-mentioned subsegments alternate in the radial circumferential direction T1 , T2 alternate with different radii. As can already be clearly seen from these figures, the respective subsegments T1 , T2 constant radii. However, it is possible to deviate from this, in particular if connections have to be produced with particularly high strength.

Then it can namely be conceivable that the individual subsegments, in particular for the reinforced formation of the step-like transitions, for example for the formation of particularly large saw teeth T1 , T2 have different, for example gradually, ie linearly increasing radii in the circumferential direction.

In addition, those in the 2A and 2 B shown subsegments T1 and T2 , which each extend over 90 degrees in the circumferential direction. However, it is also possible for three or more subsegments each with different radii to alternate along the circumferential direction.

In at least one variant, this is the radius of the sub-segment T1 at least 1.2 times larger than the radius of the sub-segment T2 . For example, is the radius of the part segment T1 two times larger than the radius of the sub-segment T2 . The reverse is also conceivable, which means that the radius of the sub-segment T2 is at least 1.2 times larger than the radius of the sub-segment T1 .

In the 3 is a schematic perspective view of a system device described here 1000 shown, it can be seen that the respective hoses and cables 2 completely through the connecting body 1 are passed through. For example, the individual cables are relative to the connector body 1 arranged immovably. In other words, the position of the hoses within the connecting body 1 not non-destructive relative to each other and also relative to the connecting body 1 be changed yourself.

The invention is not limited by the exemplary embodiments mentioned in the description; rather, the invention encompasses any new feature and any combination of features, which in particular includes any combination of features in the claims, even if this feature or this combination itself is not explicitly included in the Claims or exemplary embodiments is specified.
