[0028] FIG. 2 a sectional representation of the assembly for feeding a cable through a separating element in the mounted state;

[0029] FIG. 3 schematic perspective representations of a cable feedthrough in the assembled state;

[0030] FIG. 4 schematic representations of the assembly from FIG. 3 from the front and from the rear;

[0031] FIG. 5 schematic perspective representations of another assembly for a cable feedthrough from obliquely front and obliquely rear and

[0032] FIG. 6 schematic perspective representations of the other assembly for a cable feedthrough from FIG. 5 from the front and in section.

[0033] FIG. 1 shows a schematic perspective representation of an assembly for a cable feedthrough for feeding cables (not shown) through a separating element 1, which can be, for example, a separating wall or a housing wall, for example, a housing wall of a control cabinet or an electrical or electronic device. A feedthrough housing 2, a dividing component 3, sealing elements 4 and a screw-in and locking component 5 are provided for the cable feedthrough. Furthermore, a fastening component 6 is shown in FIG. 1, which is provided in the embodiment shown in order to secure the cable feedthrough on the separating element 1 by forming a screw connection between the fastening component 6 and the screw-in and locking component 5 (see FIG. 2).

[0034] The feedthrough housing 2 has a housing interior 7 which is delimited by a lateral housing wall 8 and a housing bottom 9. In the region of the housing bottom 9, a bottom opening 10 is formed which, in the embodiment illustrated, is designed to largely encompass the housing bottom 9 and is used to feed the cables (not illustrated) through. A seal 9a is arranged circumferentially around the bottom opening 10. In the embodiment shown, the seal 9a is formed with a web (sealing web). The seal 9a is integrally formed on the feedthrough housing 2, for example, by means of 2C injection molding. Alternatively, it can be provided that the seal 9a is detachably arranged on the feedthrough housing 2, for example, as a removable sealing ring or collar. In the installed state (see FIGS. 2 to 4) of the sealing elements 4, the seal 9a rests against said sealing elements and thus seals them laterally along a portion adjacent to the feedthrough housing 2. Here, the seal 9a is in sealing contact with a rear surface 4a of the sealing elements 4 (see particularly FIG. 2). It can be provided that the seal 9a encompasses an edge region of the sealing element 4. Alternatively or in addition, it can be provided that the seal 9a lies in a groove 4b on the sealing element 4.

[0035] The feedthrough housing 2 also has an internal screw-thread 11. A circumferential seal 13 is provided on the feedthrough housing 2 in the region of an end-face surface 12.

[0036] The dividing component 3 has intersecting dividing walls 14, so that receptacles 15 are provided into which the sealing elements 4 can be inserted when the dividing component 3 is arranged in the housing interior 7 of the feedthrough housing 2 (see FIG. 2). When inserting into the interior 7 of the feedthrough housing 2, portions 16 of the separating walls 14 on the outside or at the edge are arranged in associated guides 17 in the housing interior 7. In this way, the dividing component 3 can be arranged in a self-retaining manner in the housing interior 7, for example, in a self-clamping manner. A surface-side seal made of an elastic material can be provided in the region of the edge-side portions 16.

[0037] In the embodiment illustrated, the sealing elements 4 have a separating cut 18 in the longitudinal direction, through which a cable can be introduced in the passage 19 of the respective sealing element 4. The sealing elements 4 have a plurality of sealing lips 20 around the circumference. In a comparable manner, inner sealing lips 21 are provided in the passage 19.

[0038] The screw-in and locking component 5 has a proximal screw-thread portion 22 and a distal screw-thread portion 23, which, in the embodiment shown, are arranged on component portions having different diameters. In the illustrated embodiment, the screw-in and locking component 5 is formed in several parts with two component halves 24, 25 which can be detachably connected to one another by means of projections 26 and associated recesses 27 in order to then screw the proximal screw-thread portion 22 into the internal screw-thread 11 of the feedthrough housing 2, so that here the dividing component 3 and the sealing elements 4 are secured, particularly clamped, in such a way that an end-face surface of the screw-in and locking component 5 facing them respectively comes to rest against the dividing component 3 and sealing elements 4.

[0039] For mounting on the separating element 1 in the region of an opening 28, the distal screw-thread portion 23 can then be partially fed through the opening 28 in order to screw on the fastening component 6. A cable feedthrough designed in this way is shown in section in FIG. 2. Alternatively or in addition, it can be provided that an internal screw-thread is formed along the circumferential edge 29 of the opening 28, into which the distal screw-thread portion 23 is screwed.

[0040] FIGS. 3 and 4 show schematic representations of an assembly in which the cable feedthrough is assembled without being mounted on the separating element 1. The same reference numbers are used in FIGS. 3 and 4 as in FIGS. 1 and 2 for the same features.

[0041] FIGS. 5 and 6 show schematic representations of another assembly for a cable feedthrough. The same reference numerals are used in FIGS. 5 and 6 for the same features as in the embodiment in FIGS. 1 to 4.

[0042] Sealing elements 4 are inserted into associated receptacles 15, which are provided in the feedthrough housing 2 by means of the dividing component 3.

[0043] In contrast to the embodiment in FIGS. 1 to 4 having the screw-in and locking component 5, breakthroughs 30 are provided on the feedthrough housing 2, into which breakthroughs screw means (not shown) can be inserted in order to fasten the feedthrough housing 2 to a separating or housing wall, not shown to simplify the representation, in such a way that the circumferential seal 13 seals the housing interior 7. The seal 9a is arranged on the feedthrough housing 2 for sealing in the region of the bottom opening 10. When arranged in an inserted end position, the sealing elements 4 come to a stop here, so that a sealing effect is formed circumferentially along the circumference of the bottom opening 10. According to the sectional representation in FIG. 6, the seal 9a lies with a protruding portion 9b in an associated groove 4a on the sealing element 4. The seal 9a has, comparable to the example in FIG. 2, an L-shape in cross-section, which is optional.

[0044] The features disclosed in the above description, the claims and the drawing can be important both individually and in any combination for the implementation of the various embodiments.
