Description

Description Device for carrying out flexible long molded parts, in particular cables, pipes or hoses, through a wall of a housing provided with a through hole.

The invention relates to a device for carrying out flexible long-form parts, in particular cables, pipes or hoses, through a wall with a through-hole provided in a housing, consisting of at least one double nipple with an external thread formed at both end regions, with a perforated in a first end region Sealing and clamping insert is used and a perforated pressure screw is screwed onto this end region, by means of which the sealing and clamping insert can be clamped against the jacket of a long molded part guided through the double nipple.

Such devices, also called cable glands, are widely known. In particular, a corresponding device is known from DE 19 738 517 C1. Such a device serves to guide a flexible long molded part, for example a cable, a pipe or a hose, through a wall. The wall, which can be, for example, a housing wall, has a through-hole which is used to carry out the long molded part. In the prior art, the corresponding double nipple is inserted with its second end region into the through-hole of the wall and is fixed, for example, by means of a nut screwed against it. A perforated sealing and clamping insert is inserted on the first end area of the double nipple, and a perforated pressure screw is screwed onto the first end area. The corresponding long molded part is guided through this double nipple and the corresponding parts. For sealing, the perforated pressure screw can be tightened so that the sealing and / or clamping insert is pressed against the jacket of the long molded part, so that sealing and strain relief are achieved. Such facilities are quite suitable for the intended purpose. One problem is that if the long molded part that is carried out is not to continue in a straight line at its end that is led away from the first end region of the double nipple, but is to be angled, for example angled by 30 °, 60 ° or 90 °. In this case, the user has to bend the flexible long molded part accordingly so that it achieves the desired shape of the outlet. This results in crushing of the long molded part and possibly also deformations, which is undesirable since the long molded part carried out should be removed without kinks and without sharp bends.

Based on this prior art, the invention has for its object to provide a device of the generic type for use in the hygiene field, in which a deviating from the central longitudinal axis of the double nipple exit of the long molded part is possible, this exit is preformed and that corresponding long molded part leads accordingly, without kinks of the long molded part occurring during installation or use, and without free threads, gaps or the like posing a risk in terms of cleanability in the assembled state.

To achieve this object, the invention proposes that an angle piece is provided in the form of a hollow body, the cavity of which has a first outlet which can be inserted through the through-hole or can be positioned on it and locked in this position, and at least one second outlet , whose central longitudinal axis includes an angle deviating from 0 ° with the central longitudinal axis of the first outlet and into which the second end region of a double nipple can be fitted.

The formed in the form of a hollow body elbow can be used with the first outlet in the through hole of the wall or the like and can be locked in this position, for example by locking, screwing or in any other suitable manner. The second outlet is not directed coaxially to the first outlet, but at an angle of 30 °, 60 °, 90 °, 120 ° or 150 °, for example, which deviates from the central longitudinal axis of the first outlet. This second outlet serves to receive and hold a conventional double nipple with its second end region. Because of this configuration, it is possible to provide an angular outlet of the long molded part that is carried out without the user having to make manual angling of the long molded part. Rather, the long molded part is guided in a conventional manner through the double nipple with insert and pressure screw and through the hollow body, in particular its cavity, so that a predetermined angular alignment of the outgoing end of the long molded part is achieved. The cavity of the hollow body is designed in such a way that the long molded part guided through the hollow body and through the double nipple is positively guided and directed when it is passed through these parts, so that a corresponding alignment is made possible.

A special further embodiment is seen in the fact that the cavity of the hollow body has a plurality of second outlets, each with double nipples mounted or mountable therein with the second end region.

Such an embodiment makes it possible to pass several long molded parts through the device, for example two long molded parts being passed through the hollow body and one of these long molded parts being discharged via one of the second outlets, which has the double nipple with a correspondingly fitted insert and pressure screw. In this way, it is possible to remove a plurality of long-shaped parts by means of only one through-hole in the wall of the housing, which can optionally be removed from the hollow body in the same or different direction in accordance with the direction of the outlets.

It is preferably also provided that the first outlet of the hollow body has a threaded connector.

CH 710 959 B1 This makes it possible to insert the hollow body with the threaded connector into the through-hole, it being possible to screw a lock nut or the like onto the end of the threaded connector passing through the through-hole in order to fix the hollow body to the wall.

Another embodiment of this is seen in the fact that the threaded connector is attached to the hollow body in one piece.

In such a configuration, the assembler must ensure during assembly that not only the threaded connector is inserted into the corresponding through-hole, but that the hollow body is appropriately aligned so that the second outlet provided with the double nipple is directed in the desired direction , In this orientation, the user could screw a lock nut onto the threaded connector and bring about the final fixing of the hollow body on the wall in the desired position.

In order to allow the user a simple way of aligning the second outlets of the hollow body, it is provided that the threaded connector is inserted into a sleeve and axially immovable, but is rotatably held in the sleeve about its longitudinal axis, the sleeve in the first Outlet of the hollow body is detachably mounted, in particular screwed in, preferably sunk flush in the first outlet.

In such an embodiment, the threaded connector at the end region which is inserted into the first outlet of the hollow body can have a radially projecting collar or the like. Furthermore, the corresponding sleeve is pushed onto the threaded connector. This sleeve, in turn, has an external thread and is screwed into the internally threaded first outlet of the hollow body, the screw-in depth being chosen as far as possible so that the sleeve is flush with the first outlet. In this position the threaded connector can then be inserted through the through holes and fixed with a lock nut. Despite this arrangement, it is then possible to rotate the hollow body about the central axis formed by the threaded connector because the hollow body is rotatably arranged on the threaded connector with the sleeve screwed into it.

An alternative arrangement, which also serves to enable simple alignment of the hollow body with its second outlets, is that the threaded connector is inserted with an end region in the first outlet of the hollow body and by means of an annular groove in the outside of the threaded connector and is held axially immovable in an internal circumferential annular groove of the outlet, the hollow body being rotatable about the central axis relative to the threaded connector.

Here, the threaded connector is inserted with an end region in the first outlet of the hollow body. The threaded connector has a circumferential ring groove at this end region, and the first outlet also has a circumferential ring groove on the inside. A snap ring engages in these ring grooves, by means of which the parts are fixed to one another. The threaded connector can then be mounted so that it protrudes through the through holes and can be fixed with a lock nut. However, the mobility of the hollow body relative to the threaded connector is retained because the hollow body is rotatably held relative to the threaded connector.

A preferred embodiment can also consist in that the cavity of the hollow body has a plurality of second outlets with different or the same diameter and correspondingly adapted double nipples including insert and pressure screw.

The cavity of the hollow body can therefore have a plurality of second outlets, which can have the same diameter or different diameters corresponding to the diameter of the long molded part to be carried out and have the corresponding again adapted double nipple including insert and pressure screw.

A further preferred embodiment is seen in the fact that the angle piece at the mouth area of the first outlet has a flat support surface which is directed transversely to the central axis of the first outlet and which has a receiving groove all around on the end face and into an outer wall of the angle piece, in which an annular groove Sealing element is arranged, which projects axially beyond the support surface and is radially aligned with the support surface on the outside.

The angle piece, which is designed in the form of a hollow body, has a flat support surface directed transversely to the central axis of the outlet at the mouth region of the first outlet. This, in turn, has a receiving groove all around the front and merging into the outer wall, in which a ring-shaped sealing element is arranged, which projects axially beyond the supporting surface and is aligned radially on the outside with the supporting surface. In the target assembly position, this sealing element is clamped between the support surface and the surface of the wall that has the through-hole, so that this area is sealed. In addition, an easy-to-clean arrangement is ensured, since the sealing element is aligned with the outer casing of the contra-angle in the area of the first outlet and therefore no corners or edges are formed on which dirt could settle and which are difficult to clean.

Also for the purpose of particularly simple sealing and cleaning, it is provided that the elbow on the respective second outlet has a flat support surface which is oriented transversely to the central axis of the outlet, and that the pressure screw on an end of a collar directed towards the support surface is annular Has sealing element, which is axially clamped against the support surface in the target mounting position and does not protrude radially on the outside or only insignificantly beyond the jacket of the end of the collar.

CH 710 959 B1 The flat support surface in turn serves as a counter bearing for the sealing element provided on the end face of the pressure screw, this sealing element also not protruding beyond the jacket of the pressure screw or the jacket of the collar thereof, so that a flush arrangement of the sealing element relative to the pressure screw is achieved is. This arrangement ensures a clean seal and a simple cleaning possibility even in the area of the seal arrangement.

Furthermore, it is preferably provided that the respective double nipple between the end regions has a circumferential, radially projecting stop shoulder, which is ring-shaped or a polygon.

This arrangement provides a simple possibility to be able to screw the double nipple with a tool into the corresponding second outlet of the hollow body. The radially projecting stop shoulder, which is designed as a polygon or in a similar way as a tool grip, enables the user to enable and facilitate screwing in the double nipple into the second outlet by means of a tool.

For the same reason, it is preferably provided that the respective pressure screw and / or hollow body has tool engagement surfaces, in particular in the form of a polygon, on its jacket surrounding the first outlet.

Here, too, the corresponding tool engagement surfaces serve to facilitate assembly for the user, so that the user can screw the pressure screw onto the double nipple in a simple manner and can fix the hollow body after assembly in the area of the through-hole by means of a lock nut or the like screwed onto its threaded connector.

An additional preferred embodiment is seen in the fact that the hollow body has a plurality of second outlets which are arranged parallel to one another, at an angle to one another, one above the other or distributed over the circumference of the hollow body.

The hollow body can have a plurality of outlets, which are provided in different or the same orientation to one another, in order to provide corresponding outlet options for long molded parts.

The invention is explained below using exemplary embodiments.

In the drawings, an apparatus for carrying out flexible long molded parts, for example cables, pipes or hoses, is shown. This device is used to guide corresponding long molded parts through a wall of a housing or the like. For this purpose, the wall has a corresponding perforation through which the long molded part can be guided and on which the device is mounted in order to enable the long molded part to be passed through.

CH 710 959 B1 The device consists of a double nipple 1 with an external thread formed at both end areas, a perforated sealing and clamping insert 3 being inserted into a first end area 2 and a perforated pressure screw 4 being screwed onto this end area 2 , which is designed in the manner of a cap nut.

By means of the pressure screw 4, the sealing and clamping insert 3 can against the jacket one through the double nipple

I guided long molded part are tightened so that a seal and a strain relief takes place.

Furthermore, an angle piece 5 in the form of a hollow body 6 is provided. Its cavity 7 has a first outlet 8, which can be plugged through the corresponding through-hole in the wall and can be locked in this position, and a second outlet 9, whose central longitudinal axis 10 includes an angle deviating from 0 ° with the central longitudinal axis 11 of the first outlet 8, for example an obtuse angle of 120 ° or a right angle.

In the second outlet 9, the second end region of the double nipple 1 can be mounted, this having the insert 3 and the pressure screw 4 at the first end region 2. As a result, when the pressure screw 4 is tightened, the long molded part that is carried out is sealed and held in a strain-relieved manner.

This arrangement makes it possible for the long molded part to be carried out, for example, in the direction of the central longitudinal axis

II to lead through the wall of the corresponding part and insert it into the cavity 7, the long molded part then being continued through the hollow channel of the double nipple 1 and being guided in a different angular position from the insertion point to the corresponding position behind the wall.

The first outlet 8 of the hollow body 6 has a threaded connector 13. In a simplest embodiment, the threaded connector 13 can be made in one piece with the hollow body 6.

4, the threaded connector 13 is inserted into a sleeve 14 and in the through hole, not shown here, screwed or fixed with a lock nut and thus rotatable about its longitudinal axis in the desired mounting position, but held axially immovable in the sleeve , The sleeve 14 is detachably screwed into the first outlet 8 of the hollow body 6 in the exemplary embodiment, it being arranged flush in the first outlet 8 in the desired position, which is shown in FIG. 4. The threaded connector 13 has at its end region located in the cavity 7 a circumferential collar 15 which is supported on an inner end face of the sleeve 14. In the desired position, the threaded connector 13 inserted through the corresponding wall perforation is fixed with a screwed lock nut.

In this position, the axial mobility is blocked. The rotational movement about the central longitudinal axis 11 is retained. It is thus possible for the user to rotate and align the contra-angle 5 in accordance with its desired use.

In the embodiment according to FIG. 2, the threaded connector 13 is inserted with an end region 16 into the first outlet 8 of the hollow body 6 and engages by means of an annular groove 17 in the outer circumference 17 of the threaded connector 13 and in an inner annular groove 18 in the outlet 8 Snap ring 19 held so that the threaded connector 13 is held axially immovable, but is rotatable about its central longitudinal axis 11. Here, too, after the fixing in the perforation of the housing wall by means of a lock nut which is screwed onto the threaded connector 13, the rotational mobility of the angle piece 5 is still retained, so that an alignment of the second outlet 9 in the desired position is made possible.

6, the threaded connector 13 with a radially projecting collar 20, which carries an external thread, is screwed into a corresponding thread formation of the first outlet 8. The angle piece 5 can be aligned in the desired installation position when the threaded connector 13 passes through the corresponding perforation in the wall until the lock nut is screwed on and tightened.

1 to 6, the cavity 7 of the hollow body 6 each has only a second outlet 9, in the embodiments according to FIGS. 7 to 15, a multiple arrangement of second outlets 8 is provided on the hollow body 6, so that several Departures are formed for long molded parts. The corresponding outlets can have different or the same diameter. A suitable double nipple 1 can be screwed into each of the outlets 8.

All embodiments have in common that the angle piece 5 at the mouth area of the first outlet 8 has a flat support surface 21 directed transversely to the central axis 11 of the outlet 8, which has a receiving groove 22 all around on the end face and into the outer wall, in which a ring-shaped groove Sealing element 23 is arranged, which projects slightly axially beyond the support surface 21 in the unloaded position and is approximately radially outward aligned with the collar 20 of the hollow body 6, so that the sealing element does not project or protrude significantly beyond the outer contour in this area. This arrangement serves on the one hand to seal the support surface 21 from the housing wall which has the through-hole, and on the other hand this arrangement serves to prevent the accumulation of dirt in the area of the seal and to enable easy cleaning in this area.

For a similar purpose, the angle piece 5 on the second outlet 9 also has a flat support surface 24 which is oriented transversely to the central longitudinal axis 10 of the outlet 9. The pressure screw 4 has at one end of the collar 25 directed towards the support surface 24 an annular sealing element 26, which axially against the

CH 710 959 B1

Support surface 24 is tense and does not protrude radially or only insignificantly over the jacket of the end of the collar 25.

The double nipple 1 has between the end regions 2 and 12 a circumferential, radially projecting stop shoulder 27, which is preferably designed as a polygon, so that external engagement surfaces are formed, for example, for a wrench or another tool. The pressure screw 4 also has corresponding tool engagement surfaces 28 on its jacket, and likewise the hollow body 6 has tool engagement surfaces 29 on its jacket surrounding the first outlet 8.

In the embodiments of the hollow body 6, which have a plurality of second outlets 9, these can be directed parallel to one another, as shown in FIGS. 11 to 15, or directed at an angle to one another, as shown in FIGS. 7 and 8. These can also be arranged one above the other, as in the embodiments according to FIGS. 9 to 11 or distributed over the circumference of the hollow body 6, as shown in FIGS. 7 and 8 or FIGS. 13 to 15.

The invention enables a wide range of applications in which the long molded part is guided at an angle, the angle being determined by the structural elements and not having to be set manually by the user.
