Definitions
- the invention relates to a cable bushing for a control cabinet and a control cabinet.
- Plug connections of lower protection class are often mean much more effort when replacing cables than a plug connection on the outside of the control cabinet.
- control cabinet which is constructed in a simple way and enables a quick, tool-free change or exchange of a cable.
- Embodiments are the subject of the dependent claims.
- the present invention relates to a cable bushing for a control cabinet with a housing, which can be closed with a housing cover, the cable bushing comprising a frame open on one side, which can be releasably fastened flush to one end of the housing, with at least one removable guide element in the frame for passing a Cable is arranged.
- the change or exchange of a cable which is to be guided into the interior of a control cabinet can be done without tools, since only the guide element and the cable are removed from the frame of the
- the frame of the cable bushing which is releasably fastened to the housing, remains flush with the end face of the housing.
- the guide element can have an opening on one side
- the cable can be inserted or pressed into the guide element laterally through the slot. There is no need to thread the cable through the housing, which may be provided with a plug, since the cable can be pressed into the guide element, regardless of the size of the plug.
- the guide element can preferably be made of a polymer or an elastomer, e.g. B. a thermoplastic elastomer or rubber exist.
- a polymer or an elastomer e.g. B. a thermoplastic elastomer or rubber exist.
- Contamination can penetrate into the housing via the guide element, since the guide element surrounds the cable in a dust-tight or fluid-tight manner, in particular mechanically contacts or clamps the cable jacket.
- the frame of the cable bushing can have a plurality of guide elements in different sizes for receiving cables with different diameters. Because of the different In the embodiment of the guide elements, cables of different diameters are also enclosed in a fluid-tight manner and guided safely.
- a control cabinet is provided with a
- the housing cover of the housing of the control cabinet having a circumferential sealing element which, when the housing is closed, rests against the end face and locks and seals the frame and the at least one guide element in a fluid-tight manner.
- the guide elements and the frame are sealed against dust, water or other contamination that can get into the housing and are also securely held or locked in position. Individual guide elements can therefore not slip out of the frame.
- the housing cover is detachably arranged on the housing by means of hinges. Due to the detachable attachment, the
- the housing cover should be temporarily removed when changing or exchanging the cables or when assembling the frame
- Housing cover may not be sufficient when the housing cover is attached to the housing.
- the housing of the control cabinet has a recess in which the frame of the cable bushing can be fastened and wherein the frame covers the recess in areas.
- the cable guide can be inserted flush with the end face of the housing, so that the sealing lip of the housing cover can also rest flush.
- Fig. 2 shows a control cabinet with cable feed-through when it is open
- Housing cover; 3 shows a control cabinet with a cable duct with a closed
- the cable bushing 1 is in a perspective view for a
- Control cabinet 2 with a housing 3 can be seen.
- the control cabinet 2 can be closed with a housing cover 4, not shown here.
- the cable bushing 1 comprises a frame 5 which is open on one side and which is formed from a plastic. It would also be conceivable to use other materials, for example metal.
- the frame 5 is releasably fastened flush on an end face 6 of the housing 2.
- the fastening takes place via a screw connection 7.
- further fastening means for example gluing or a press fit, can also be used.
- the cable bushing 1 has guide elements 8a-8f which are detachably arranged in the frame 5.
- the guide elements 8a-8f serve to lead through a cable 9a, 9b into an interior 10 of the housing 2.
- an opening 11a-11f is provided in the form of a slot.
- the cable 9a, 9b is pressed into the guide element 8a-8f through this opening 11a-11f.
- the cable 9a, 9b can again be removed or pressed out of this opening 11a-11f from the guide element 8a-8f.
- the guide elements 8a-8f consist of a polymer or an elastomer such as rubber, the guide elements 8a-8f are deformable to a certain extent. That is to say, after the cable 9a, 9b has been pressed in, the guide elements 8a-8f lie in a fluid-tight manner around the cable 9a, 9b and thus protect against the ingress of dust, splash water or other contamination of the interior 10 of the housing 2.
- the guide elements 8a-8f that are not required can also consist of one Be designed solid material so that the control cabinet 2 is still protected against the ingress of dust, spray water or other contamination.
- the frame 5 has grooves 12 in which webs 13 formed on the guide elements 8a-8f engage or are guided in them. For the sake of clarity, this is only shown on one guide element.
- the guide elements 8a-8f are designed in different sizes, so that the cable 9a, 9b can be passed through in different diameters while still providing a fluid-tight seal.
- a control cabinet 2 is shown with a cable bushing 1 releasably fastened to the housing 3 without a cable 9a, 9b passed through
- housing 3 the housing cover 4 is arranged by means of hinges 14, so that the housing cover 4 can close the housing 2. Furthermore, at the
- Housing cover 4 a circumferential sealing lip 15 is arranged, which also consists of a polymer or elastomer, e.g. rubber.
- Control cabinet 2 is shown, the housing cover 4 being arranged on the hinges 14.
- the sealing lip 15 lies on the end face 6 of the housing 3 and thus also on the frame 5 and the
- the guide elements 8a-8f and the frame 5 are through the application of the
- Sealing lip 15 is locked and also sealed in a fluid-tight manner. In other words, the penetration of dust, splash water or other contamination into the housing 2 is prevented.
