Description

Device for the sealing passage of lines through a separating element Description

The invention relates to a device for the sealing passage of lines, e.g. in the form of individual wires of an electric cable, through a separator, e.g. a partition, according to the preamble of claim 1. Such a device comprises a holding part with a plurality of seals, which are each provided for sealingly receiving a (electrical or optical) line, and a guide member which is to be arranged in an opening of the separating element, through which the lines are intended to be passed. Under a separating element is generally understood here an element through which lines are to be passed sealingly, so that along the lines no moisture, pollutants or the like. From one side to the other side of the separating element can get. From GB 2 115 238 A a device for sealing passage of lines through a partition wall is known in which the guide member forms a housing which on the one hand encloses an associated, the seals containing holding part and which on the other hand engages through an opening in the partition. In the embodiment of a device for the passage of lines through an opening of a separating element is generally the problem that on the one hand the individual lines within the holding part of the seals provided there are to be reliably sealed and that at the same time a reliable seal the interface between the separator and the Guide part should be guaranteed.

The invention is based on the problem of providing a device for the passage of lines through an opening of a separating element, which ensures a high density with a simple structure.

This problem is solved according to the invention by providing a device having the features of claim 1. Thereafter, the holding part and the guide part of the device in such a way (movable) with each other that they can be locked together in at least two different connection positions, wherein the guide member in a first connection position allows a relaxation of the seals of the holding member, while the guide member in a second connection position the seals deformed to seal the respective associated lines.

In this case, the holding part on the one hand and the guide part on the other hand each be integrally formed or composed of several components.

The solution according to the invention is based on the recognition that by connecting the holding part and the guide part first in a first connection position, with (compared to the second connection position) relaxed seals of the holding part, the individual lines are passed in a simple manner by a respective associated seal can, while after the transfer of guide member and holding part in the second connection position, a reliable sealing of the said lines by means of the respectively associated, now deformed seal can be achieved. The first connection position thus corresponds to a mounting position of the holding part and guide part; and the second connection position corresponds to an operating position.

It can be sealed at the same time in the second connection position by the action of the guide member on the seals of the holding part and any free spaces between those seals.

The holding part and the guide part are locked in the respective connection position relative to each other, in particular by positive locking. For this purpose, stops may be provided on the holding part on the one hand and on the guide part on the other hand, via which those two parts are supported in the respective connecting position to each other.

It can be provided in particular that the support member and the guide member in the first connection position, in which the guide member does not act on the seals of the holding member to deform them, supported along one direction via inclined surfaces to each other. The inclined surfaces extend inclined to the direction along which the guide member and the holding member from the first connection position can be converted into the second connection position, in which latter the guide member acts on the seals of the holding member to these deform. It can be achieved by a corresponding force with a force direction corresponding to the direction of a relative movement of the guide member and holding part from the first connection position to the second connection position, that the inclined to each other extending stop surfaces slide together. As a result, the connection between the guide part and the holding part can be canceled in the first connection position, and the two parts can be transferred into the second connection position. For this purpose, moreover, the holding part and / or the guide part can be designed limited elastically deformable. The guide part and the holding part can be movable in particular along that direction from the first connecting position into the second connecting position, along which the lines are guided in the seals of the holding part. To guide a respective line, in particular in the form of a wire, in a seal, the latter can have a corresponding passage opening.

A respective seal is designed so that an associated line can be inserted into its passage opening or can be passed through it, when the guide member and the holding member are in the first connection position. When transferring the two parts in the second connection position, the guide member then acts on the seals in such a way that they are deformed, resulting in a seal of a respective line in the associated seal result. That is, the inner wall of the through hole of a respective seal seals against the pipe therein. To act on the seals of the holding part can be provided on the guide part inclined surfaces which are inclined to the direction along which the guide member and the holding member from the first connection position in the second connection position can be transferred. As a result, those inclined surfaces act with a force component transverse to said transfer or movement direction on the seals in order to deform them so that they are pressed to seal against the respectively associated line. Alternatively or additionally, the inclined surfaces exert on the seals a force along the direction of movement from the first connection position to the second connection position. In general, acting surfaces can be provided on the guide part, via which the guide part in the transfer to the second connecting position acts on the seals of the holding part in such a way that they are compressed to give them sealing to create a respective associated line. The upsetting of the seals can take place along the direction of movement, along which the transfer of guide part and holding part from the first connection position takes place in the second connection position, and / or transverse to that direction. In addition, any free spaces between the seals can be sealed by the action surfaces of the guide part.

For further guidance of the pipe sections emerging from the seals, the guide part can have corresponding guide channels.

Advantageously, the guide part has a sealing surface protruding from the holding part in the second connecting position, via which the guide part seals against the inner wall of an opening of a separating element, e.g. a sleeve provided on the opening of the separating element, can be applied in order to allow a sealed passage of the lines provided in the feedthrough device through that separating element. The sealing surface can be formed in particular by a (circular in cross-section) outer wall of the guide member.

Furthermore, a stop can be provided on the holding part and / or on the guide part, by means of which the feedthrough device defined can be applied to an associated separating element (for example in the form of a dividing wall) or a sleeve provided there.

Further details and advantages of the invention will become apparent in the following description of an embodiment with reference to the figures.

Fig. 4, the holding part and the guide member together with a severed by this separation element.

Fig. 1 shows a holding part 1 of a device for conducting lines, e.g. of individual wires of a cable, by a separating element, in particular by an opening of the separating element.

The holding part 1 has an annular circumferential side wall 10, which in

Embodiment is designed circular in cross-section, and a bottom eleventh

The bottom 1 1 closes the defined by the annular peripheral side wall 10 interior 15 of the holding part 1 on one side.

In the interior 15 of the holding part 1, a plurality of seals (sealing elements 3) are arranged, each having a passage opening 35 for a line, in particular in the form of a respective single core of a cable. The extension of the passage openings 35 of the sealing elements 3 coincides in the exemplary embodiment with the axial direction a, along which the side wall 10 of the holding part 1 protrudes from the bottom 1 1.

The individual sealing elements 3 are designed in the embodiment as separate components. Alternatively, however, the seals may also be components of an integrally molded seal assembly.

The sealing elements 3 consist of a (soft elastic) material, which can be deformed under forces in action. In the undeformed state of the sealing elements 3 shown in FIG. 1, their passage openings 35 have such a cross-section that a line can be led through a respective sealing element 3, which is to be sealed by means of the corresponding sealing element 3. In the deformed state of the sealing elements 3, which will be explained below with reference to FIG. 2B, sets a respective sealing element 3 with the inner wall of its respective passage opening 35 to an associated line to seal them.

From the inner surface 16 of the side wall 10 of the holding part 1 are stops 17, 18, which serve to connect the holding part 1 with an associated guide part 2, such as shown with reference to FIGS. 2A and 2B. In the exemplary embodiment, a plurality of stops 17 of a first type and a plurality of stops 18 of a second type along the circumferential direction of the side wall 10 are arranged one behind the other. The stops 17 of the first type and the stops 18 of the second type have a different position along the axial direction a on the inner surface 16 of the side wall 10.

Further, on the inner surface 16 of the side wall 10 guide webs 19 a, 19 b are provided, which serve to guide the guide part 2, when it is moved along the holding part 1 in order to act on the sealing elements 3.

The sealing elements 3 are fixed to the holding part 1. This is done in the embodiment of FIG. 2A, characterized in that the sealing elements 3 are arranged on the bottom 1 1 of the holding part 1. For this purpose, a respective sealing element 3 on a mounting portion 30 which is inserted into an associated mounting opening 12 of the bottom 11.

It can further be seen from FIGS. 1 and 2A that the sealing elements 3 each have a deformable section 32 which is provided with lateral elevations 34. Both the attachment portion 30 and the deformable portion 32 of a respective sealing element 3 are thereby penetrated by one of the through holes 35.

Fig. 2A also shows a guide part 2, which is connected to the holding part 1 in a first connection position. The guide member 2 has guide channels 25 which are aligned with the through holes 35 of the sealing elements 3 at the intended connection between the holding part 1 and guide part 2. Thus, through a respective passage opening 35 of a sealing element 3 and the associated guide channel 25 of the guide member 2, a conduit, e.g. in the form of a single wire of a cable to be passed. The respective line thus engages through the passage device formed by the holding part 1 and the guide part 2.

The guide part 2 comprises a base section 21 accommodated in the interior 15 of the holding part 1 and a guide section 22 projecting therefrom (in the axial direction a), which protrudes from the holding part 1. The guide portion 22 defines an outer wall 20, over which the feed device formed by the holding part 1 and the guide member 2 sealingly against the inner wall of an opening of a Separating element, for example, provided at the opening sleeve can create, as shown in Fig. 4.

For locking the holding part 1 and the guide part 2 in the first connection position shown in Fig. 2A, a positive connection is provided. For this purpose, the stops 15, 18 projecting into the interior 15 of the holding part 1 are associated with corresponding stops 27, 28 on the outside of the guide part 2. In the first connecting position shown in FIG. 2A, the holding part 1 and the guide part 2 received therein with a base section 21 are supported on first stop pairs 17, 27 along a first direction and on second stop pairs 18, 28 along a second, opposite direction, so that a total positive locking of holding part 1 and guide part 2 is achieved in the first connection position. The respective support direction in this case runs along the (axial) direction (a), along which the guide part 2 (with its base portion 21) can be inserted into the holding part 1. Along this direction extend in the embodiment, the through holes 35 of the sealing elements 3 and the guide channels 25 of the guide member second

Along the other spatial directions, i.e., perpendicular to the aforementioned support direction, the guide part 2 (or its base part 21) is secured to (in) the holding part 1 by its peripheral side wall 10 (including the guide webs 19a, 19b).

In addition, in the first connection position, the seals 3 are held captive in the holder 1 by the guide part 2 (or by its regions at a front end 23). It is also clear from FIG. 2A that the first pairs of stops 17, 27 abut one another via inclined surfaces 17a, 27a, which in each case run inclined to the support direction (axial direction a). By a corresponding forces in effect along the supporting direction on the guide part 2 and / or the holding part 1 can therefore be achieved that the inclined stop surfaces 17a, 27a of the first stop pairs 17, 27 slide on each other. In a limited elastically deformable embodiment of the holding part 1 and / or the guide part 2, this allows a running over of the corresponding stop pair 17, 27, so that the guide member 2 relative to the Holding part 1 (along the axial direction a as a transfer direction) can be transferred from the first connection position shown in Fig. 2A in the second connection position shown in Fig. 2B. In the second connection position, the guide part 2 and the holding part 1 are also positively held to each other in the embodiment in turn in such a way that the holding part 1 and the guide member 2 at different pairs of stops 17, 27; 1 1, 23 in the opposite direction (in each case along the transfer direction / axial direction a) abut each other.

Specifically, in the second connection position, the holding part 1 and the guide part 2 in the embodiment on the one hand on second stop surfaces 17b, 27b of the first pairs of stops 17, 27, and on the other hand with an axial end 23 of the guide member 2 (optionally also indirectly via at least one intermediate Component) on the bottom 1 1 of the holding part. 1

On the guide part 2, in the embodiment specifically in the region of one (front) axial end 23, there are provided reaction surfaces 29 which are inclined to the transfer direction (axial direction a), along which the guide part 2 and the holding part 1 from the first connection position can be brought into the second connection position. With these contact surfaces 29, the guide part 2 acts on the sealing elements 3, more precisely on the respective sealing portions 32, when the guide part 2 and the holding part 1 have been transferred from the first connecting position to the second connecting position, which is shown in FIG. 2B. In the exemplary embodiment, the action takes place concretely on the laterally protruding projections 34 of a respective sealing element 3. As a result, a respective sealing element 3 is compressed so that the inner wall of its respective passage opening 35 abuts against the respective associated, guided through line. Specifically, in the embodiment, a respective sealing element 3 is compressed both axially and radially by the inclined extending surfaces 29 (compressed). In addition, the guide part 2 (in particular with the contact surfaces 29) also seals free spaces between the sealing elements 3 in the holding part 1.

In addition, in the second connection position, the sealing elements 3 are fixed by the action of the guide part 2 in the holding part 1 (or more precisely in the bottom-side openings 12). As a result, in the feedthrough device 1, 2 (through the through holes 35 of the sealing elements 3 and through the guide channels 25 of the guide member 2) extending lines form a sealed harness. This can in turn be sealingly passed through a passage opening of a separating element, by serving as an outer sealing surface outer wall 20 of the guide member 2, which projects according to Figures 2B and 3 in the second connection position from the interior 15 of the holding part 1, sealingly against the inner wall that passage opening or a sleeve provided there applies. This is shown in FIG. 4. 4 passes through the feedthrough device 1, 2 with the projecting out of the holding part 1 and serving as a sealing surface outer wall 20 of the guide member 2 an opening 101 of a separator 100. The to-swept opening of the separator 100 is limited by one of an elastic material (eg Rubber) existing sleeve 4 ("rubber spout), which has a ring-shaped in cross-section, hollow cylindrical in the embodiment, sealing portion 42, on the inner wall 40 (inner surface), the feedthrough device 1, 2 on the (acting as a sealing surface) outer wall 20 of the 2 can create management part. For this purpose, the outer diameter of the guide part 2 in the region of the outer wall 20 is selected such that it rests sealingly against the inner wall / inner surface 40 of the sleeve 4 when the guide part 2 is arranged in the opening of the separating element 100.

The sleeve 4 can be connected as a separate component with the separator 100 or integrally formed hereby. In the second case, the sleeve 4 can simultaneously form the separating element.

For defined positioning of the feedthrough device 1, 2 on the separating element 100 is the former via a stop 13 which is formed on a bottom 1 1 facing away from (axial) portion of the holding part 1, on the sleeve 4, more precisely at one end 43 of the sealing portion 40. In addition, at least one provided on the guide part 2 pin 24 (in the embodiment, a plurality of pins 24 in the form of lugs) engages behind the sleeve 4 on the side facing away from the holding part 1.

In Fig. 4, one of the lines L is also exemplified by dashed lines, which is guided by means of the feedthrough device 1, 2. The line L engages on the one hand, one of the seals 3 of the holding part or its passage opening 35 and the other an adjoining guide channel 25 of the guide part. 2
