Component holder for electromechanical components

Description

TECHNICAL AREA

[0001] The invention relates to a component holder by means of which electromechanical components can be fixed to a metal rail. Such a component holder can, for example, be designed as a corrugated conduit holder for fastening and guiding conduits in the form of corrugated conduits. A corrugated conduit is generally a flexible plastic tube used for installing electrical cables. This allows for the orderly and protected routing and fastening of cables in electrical installations. Corrugated conduits can also serve to prepare for the later replacement or retrofitting of wired supply lines. STATE OF THE ART

[0002] Corrugated pipe holders are already known in the prior art. These holders typically have a C-shaped receptacle into which the corrugated pipe can be clipped. The receptacle is attached to a corrugated pipe base or is integrally molded into it. Depending on its design, this corrugated pipe base can, for example, be fixed in position within a recess in a metal rail. Alternatively, the corrugated pipe base can also have a connection for screw fastening.

[0003] Relevant prior art is disclosed in US 2016 / 025244 A1, US 2018 / 045335 Al and EP3296461 Al. PRESENTATION OF THE INVENTION

[0004] Based on this prior art, the invention aims to provide an improved component holder that can be attached to different metal rails as easily as possible.

[0005] The component holder according to the invention is defined by the features of main claim 1. Further developments of the invention are the subject of subsequent claims.

[0006] The component holder according to the invention has a fastening unit by means of which an electromechanical component can be attached to the component holder. Furthermore, at least one retaining element is provided. The component holder can be attached to a metal rail by means of the retaining element. According to the invention, the retaining element is approximately L-shaped and has a first leg and a second leg, which are arranged approximately perpendicular to each other. At least one hook element is provided on the first leg, so that a metal rail can be clamped between the hook element and the second leg. In order to be able to attach the component holder to metal rails of different depths, preferably two hook elements can be provided on the first leg. Thus, a first, inner hook element can be provided, the distance to which is less than the distance of the second leg to a second, outer hook element.The first hook element can be used for attachment to shallower metal rails. If the first hook element is removed, the second hook element can be used to attach to deeper metal rails. To allow for easy and clean removal of the first hook element, it can have a predetermined breaking point, preferably located at the connection point between the hook element and the first leg. The first hook element can then be broken off from the first leg, for example, using pliers, allowing the component holder to be attached using the second hook element. This eliminates the need to keep different component holders in stock and allows for quick adaptation of the component holder to metal rails of varying depths.

[0007] The second leg of the retaining element may preferably have at least one fastening element to fix the component holder to the metal rail. In this case, the fastening element may have at least one opening, allowing the component holder to be screwed to the metal rail.

[0008] Preferably, the fastening element can have at least one inwardly facing locking pin. Such a locking pin can be inserted into a front-facing recess of the metal rail, thus enabling fixation along the length of the metal rail. Preferably, at least two locking pins can be present, which can engage in adjacent recesses. To allow for screw fastening despite the locking pins, the at least one locking pin can have at least one predetermined breaking point, preferably located in the area where the locking pin connects to the second leg of the retaining element. The at least one locking pin can then be broken off, for example, using pliers, so that the resulting opening in the second leg aligns with one of the recesses in the metal rail, allowing for screw fastening.

[0009] In a particularly preferred embodiment, the at least one locking pin can be integrally formed on a resilient cantilever. In this case, the at least one locking pin can have a first and a second outer contour, with the first outer contour being located in the connection area of ​​the resilient cantilever. By forming two different outer contours, the locking pin can be inserted into different recesses of the metal rail. The component holder can thus be positioned independently of the shape of the recesses in the metal rail without requiring any modification of the component holder. The first outer contour, located in the connection area of ​​the resilient cantilever, can be adapted to the larger recess of the metal rail, while the second outer contour can be adapted to the smaller recess of the metal rail.Typically, the larger recess in the metal rails has a square contour, while the smaller recesses are circular. Accordingly, the first outer contour of the locking pin can be approximately square or rectangular; the second outer contour can be approximately circular.

[0010] To remove the locking pin from the recesses in the metal rail as gently as possible and to detach the component holder from the metal rail, the spring-loaded locking tongue can have an actuating element located approximately above the locking pin. Such an actuating element can, for example, be designed as a groove. A tool, particularly a screwdriver, can be inserted into this groove to lift the spring-loaded locking tongue and remove the locking pin from the recess.

[0011] Preferably, at least one fastening element can be provided on the first leg of the retaining element to fix the component holder to the metal rail. This fastening element should be arranged between the second leg and the first, inner hook element. In this way, the fastening option can be implemented regardless of the design of the metal rails. Preferably, the fastening element can have at least one inwardly facing locking pin. Such a locking pin can be inserted into a lateral recess in the metal rail, thus enabling fixation along the longitudinal direction of the metal rail. Preferably, at least two locking pins can be provided that can engage in adjacent recesses.

[0012] In a particularly preferred embodiment, the first hook element can be designed as a cantilever. In this case, the second, outer hook element can have a bend pointing towards the second leg. The first, inner hook element can be set back from the second, outer hook element. Due to the geometry of the different metal rails, such a component holder can be attached to different metal rails without having to remove the inner hook element. Such a component holder is particularly flexible in its application, without requiring any special adaptation to different metal rails. Furthermore, a spring tongue can be present in the area of ​​the first leg, running between the second leg and the first, inner hook element. At the level of the first, inner hook element, the spring tongue can have a hook bend.This hook bend allows the component holder to grip the edge of flatter metal rails, ensuring secure attachment. On deeper metal rails, the spring-loaded tongue can be deflected, allowing the hook bend to be set back, similar to the cantilever, and enabling attachment using the second hook element.

[0013] In a first embodiment, the component holder can be designed as a corrugated tube holder. In this case, the fastening unit is designed as a C-shaped corrugated tube receptacle. In a particularly preferred embodiment, at least one cable holder can be provided on at least one of the two legs of the corrugated tube receptacle. In this way, individual cables can be guided and secured by the corrugated tube holder in addition to the corrugated tube itself. This eliminates the need for additional components for securing and guiding the cables, which can be particularly advantageous in confined spaces.

[0014] Preferably, at least one cable holder can be provided on each leg of the corrugated tube receptacle. In particular, several cable holders can be provided; the individual cable holders can be designed for cables of different thicknesses. The at least one cable holder can preferably be integrally molded onto at least one leg of the corrugated tube receptacle.

[0015] Preferably, the guide axis of the corrugated tube holder and the guide axis of the at least one cable holder can run parallel to each other. The cables guided by the cable holders thus run parallel to the corrugated tube, resulting in a clear and organized cable routing.

[0016] The guide axis of the corrugated conduit holder and the guide axis of the retaining element for the metal rail can preferably run parallel to each other. The corrugated conduit is thus guided parallel to the metal rail, allowing for space-saving and clear routing of the corrugated conduit and consequently also of the cables guided within it.

[0017] To prevent the corrugated pipe from slipping in the corrugated pipe holder, the holder can have at least one profile spring on its C-shaped corrugated pipe receptacle, which can engage in one of the zigzag grooves of the corrugated pipe. This provides strain relief for the corrugated pipe.

[0018] In a second embodiment, the component holder can have a perforated mounting plate as a fastening unit. Various components can be attached to such a perforated mounting plate. For example, DIN rail brackets, corrugated pipe holders, clamps, cover holders, or the like can be attached to such a plate. The perforated mounting plate can preferably be arranged parallel to the second leg of the holding element, so that after the component holder is mounted, the mounting plate is approximately vertically oriented and allows for front-side fastening of the individual components.

[0019] The perforated grid plate can be positioned in the area of ​​the first leg of the retaining element. In this case, the perforated grid plate is approximately at the same height as the metal rail, so that the individual components can be positioned next to the metal rail using the perforated grid plate.

[0020] Alternatively, the perforated panel can be attached to the mounting element using a spacer. In this case, the spacer can be aligned with the first leg of the mounting element. This positions the perforated panel a certain distance above the metal rail, allowing the individual components to be positioned above the metal rail using the perforated panel.

[0021] In a third embodiment, the at least one mounting unit can be designed as a DIN rail or a T-rail. The DIN rail or T-rail can preferably be aligned parallel to the second leg of the mounting element, so that front mounting of the components to the DIN rail or T-rail is possible. The DIN rail or T-rail can be arranged in the area of ​​the first leg of the mounting element or as an extension of the second leg of the mounting element.

[0022] In a fourth embodiment, the at least one mounting unit can be designed as a DIN rail holder. In this case, the DIN rail holder can have two lateral guide grooves in which one edge of a DIN rail can be positioned. One of the two lateral guide grooves can be stationary, while the other can have a movable locking hook. This movable locking hook can form the top of the guide groove. The DIN rail can thus initially be inserted at an angle into the stationary guide groove. The DIN rail is then guided from above past the locking lug of the movable locking hook, so that the locking hook is deflected accordingly. After the movable locking hook snaps back into place, the edge of the DIN rail can then be securely held in the guide groove.Such a design with one stationary and one movable guide groove has the advantage that, on the one hand, the movable guide groove facilitates the insertion of the DIN rail, while on the other hand, the stationary guide groove ensures sufficient stability. With two movable guide grooves, however, there would be a risk that the DIN rail could detach from its mounting under heavy loads. Since heavy equipment is typically mounted on DIN rails, a secure and stable mounting of the DIN rail bracket is particularly important.

[0023] Preferably, the movable locking hook can have a locking lug with a convex outer contour. The curved, rounded outer contour has the advantage that the locking hook deflects more easily when sliding along the edge of the DIN rail. Therefore, less force is required to deflect the locking hook, significantly simplifying the installation of the DIN rail.

[0024] The first leg of the retaining element may have a second mounting unit for another electromechanical component. This second mounting unit could, for example, be another perforated plate. Alternatively, the second mounting unit could have at least one groove and / or at least one tongue of a tongue-and-groove connection.

[0025] The component holder according to the invention is based on the fundamental principle of screwless or tool-free technology. The component holder can therefore be assembled entirely without tools, as no screw fixings are required. This significantly reduces assembly time.

[0026] Further advantages and features of the invention can be seen in the features further specified in the claims and in the exemplary embodiments below. BRIEF DESCRIPTION OF THE DRAWING

WAYS TO IMPLEMENT THE INVENTION

[0028] A first embodiment of the component holder 10 according to the invention is described in the Figs. 1 and 2 The component holder 10 is shown in perspective. In this case, it is designed as a corrugated pipe holder. The corrugated pipe holder 10 has a C-shaped corrugated pipe receptacle 12 as a fastening unit into which a corrugated pipe 14 can be clipped (see Fig. 5 The corrugated pipe receptacle 12 has an internally circumferential profile spring 16. This profile spring 16 can engage in a groove 18 of the corrugated pipe 14, so that the corrugated pipe 14 is held in the corrugated pipe receptacle 12 in a positionally fixed and strain-relieved manner.

[0029] The C-shaped corrugated pipe holder 12 has two legs 20, 22 which are integrally formed on a retaining element 24. The retaining element 24 is approximately L-shaped and has a first leg 26 and a second leg 28, which are oriented approximately perpendicular to each other. The two legs 20, 22 of the corrugated pipe holder 12 are located on the first leg 26 of the retaining element 24.

[0030] In the present example, a first, inner hook element 30 and a second, outer hook element 32 are integrally formed on the side of the first leg 26 facing away from the corrugated pipe holder 12. The distance between the first hook element 30 and the second leg 28 is chosen such that a metal rail 34 with a depth of approximately 15 millimeters can be clamped between the first hook element 30 and the second leg 28, thus enabling the corrugated pipe holder 10 to be attached to the metal rail 34.

[0031] To attach the corrugated pipe holder 10 to a deeper metal rail 36 (see Fig. 4 To enable the metal rail 36 to be attached, the inner hook element 30 has a predetermined breaking point 38 located directly at the connection point to the first leg 26 of the retaining element 24. The first hook element 30 can be broken off at this predetermined breaking point 38, particularly using pliers, so that the metal rail 36 can be clamped between the second leg 28 and the outer hook element 32.

[0032] In the present example, the second leg 28 of the retaining element 24 has a central opening 40. This central opening 40 can be used for a screw fastening (not shown here). The opening 40 thus serves as a fastening element for fixing the corrugated pipe holder 10 in the longitudinal direction 42 and in the transverse direction of the metal rail 34, 36.

[0033] Furthermore, in this example, two inwardly pointing locking pins 44 are integrally formed on the second leg 28. The two locking pins 44 can engage in recesses 46 of the metal rail 34, 36, thus also enabling the corrugated pipe holder 10 to be fixed longitudinally 42 along the metal rail 34, 36. The locking pins 44 therefore also serve as fastening elements. In this example, the locking pins 44 are arranged such that the opening 40 does not align with a recess 46 of the metal rail 34, 36 when the locking pins 44 engage in the recesses 46. Therefore, in order to mount the corrugated pipe holder 10 to the metal rail 34, 36 using a screw fastening, the locking pins 44 must be removed. The locking pins 44 can therefore have a predetermined breaking point, not shown here, which should preferably be located directly in the connection area to the second leg 28 of the retaining element 24.The locking pins 44 can therefore be broken off if necessary, especially using pliers, so that screw fastening is possible.

[0034] If the second leg 28 of the retaining element 24 is wider, and more recesses 46 of the metal rail 34 are covered by the second leg 28, the locking pins 44 could also be arranged so that the opening 40 can align with one of the recesses 46 of the metal rail 34. In this case, the predetermined breaking point of the locking pins 44 could also be omitted.

[0035] In the present example, two cable holders 50, 52 are integrally formed on the leg 20 of the corrugated tube receptacle 12 that faces the second leg 28 of the retaining element 24. Cable holder 50 is designed for cables 54 with a diameter of four to nine millimeters, while cable holder 52 is designed for cables 56 with a diameter of three to seven millimeters (see figure). Fig. 5 ).

[0036] In contrast to the embodiment shown here, more or fewer cable holders 50, 52 could also be present on leg 20. Additionally or alternatively, one or more cable holders 50, 52 could also be present on the other leg 22 of the corrugated tube holder 12. The individual cable holders 50, 52 could also be connected to legs 20, 22 of the corrugated tube holder 12 via predetermined breaking points, so that the unused cable holders 50, 52 can be removed if necessary.

[0037] To ensure clear routing of the corrugated tube 14 and the cables 54, 56, the guide axis 60 of the corrugated tube holder 12 (corresponding to the longitudinal direction of the corrugated tube 14) runs parallel to the guide axis 42 of the retaining element 24 (corresponding to the longitudinal direction 42 of the metal rail 34, 36). The corrugated tube 14 thus runs parallel to the metal rail 34, 36 to which the corrugated tube holder 14 is attached. The guide axes 62, 64 of the two cable holders 50, 52 also run parallel to the guide axis 60 of the corrugated tube holder 12. Therefore, the cables 54, 56 also run parallel to the corrugated tube 14 and thus also parallel to the metal rails 34, 36.

[0038] A second embodiment of the component holder 70 according to the invention is described in Figs. 6 and 7The component holder 70 is shown in perspective. It has a retaining element 24, as already described in connection with the corrugated tube holder 10. The fastening unit 72 of the component holder 70, however, is designed as a perforated plate 72. The perforated plate 72 runs parallel to the second leg 28 of the retaining element 24. The perforated plate 72 is directed away from the second leg 28 and integrally formed with the first leg 26. The perforated plate 72 is positioned approximately midway between the inner hook element 30 and the second leg 28. The size of the perforated plate 72 can, in principle, be freely chosen. As a rule, however, the perforated plate 72 should only have one or at most two slots of perforation to ensure the stability of the component holder 70's fastening to the metal rail 34, 36.Depending on the required length of the perforated grid plate 72, several retaining elements 24 could also be provided, so that there should be no limitations regarding stability.

[0039] If the component holder 70 is attached to a metal rail 36 (see Fig. 7 ) or 34, the perforated plate 72 lies next to the metal rail 36, 34. A DIN rail holder 74 can, for example, be attached to the perforated plate 72, as shown in Fig. 7 as shown. Instead of the DIN rail holder 74, other components that can be fixed to a corresponding hole pattern could also be attached to the component holder 70.

[0040] A third embodiment of the component holder 80 according to the invention is described in Figs. 8 and 9The component holder 80 is shown in perspective. It has a retaining element 24, as already described in connection with the corrugated pipe holder 10. In this example, the component holder 80 has a first fastening unit 82, which is designed as a perforated plate 82. The perforated plate 82 is integrally formed with the retaining element 24 via a spacer 84. The spacer 84 is aligned with the first leg 26 of the retaining element 24. When the component holder 80 is attached to a metal rail 34, 36 (see Fig. 10The perforated plate 82 is located above this metal rail 34, 36. A DIN rail holder 74, for example, can be attached to the perforated plate 82. In addition to the perforated plate 82, the component holder 80 has a second mounting unit, which in this example has two cantilever elements 86, each with a groove 88. The cantilever elements 86 with the grooves 88 are integrally formed on the two edge regions of the first leg 26 of the retaining element 24. The cantilever elements 86 are located approximately midway between the second leg 28 of the retaining element 24 and the inner hook element 30. A suitable component 90 with corresponding springs can be inserted into the groove 88, as shown in the example in Fig. 11 The component 90 is shown. In this example, component 90 is designed as terminal 90.

[0041] A fourth embodiment of the component holder 100 according to the invention is described in Figs. 12 and 13The component holder 100 has a retaining element 24, as already described in connection with the corrugated pipe holder 10. The fastening unit 102 is designed as a T-rail 102. The T-rail 102 runs parallel to the second leg 28 of the retaining element 24 and is integrally connected to the retaining element 24 via a connecting plate 104. The connecting plate 104 is flush with the second leg 28 of the retaining element 24. A clamp 106, for example, can be attached to the T-rail 102 (see Fig. 15 ) are attached. Depending on the desired length of the T-rail 102, several retaining elements 24 could also be provided.

[0042] A fifth embodiment of the component holder 110 according to the invention is described in Fig. 14The component holder 110 has two retaining elements 24, as already described in connection with the corrugated pipe holder 10. The mounting unit 112 is designed as a DIN rail 112. The DIN rail 112 runs parallel to the two second legs 28 of the retaining elements 24 and is integrally connected to the two retaining elements 24 via a connecting plate 114. The connecting plate 114 is integrally formed on the first legs 26 of the retaining elements 24 at approximately the height of the inner hook elements 30. Various components can be attached to the DIN rail 112. Depending on the length of the DIN rail 112, a single retaining element 24 may be sufficient. For longer DIN rails 112, however, additional retaining elements 24 can be provided.

[0043] A sixth embodiment of the component holder 120 according to the invention is described in the Figs. 16 to 19The fastening unit 122 is designed as a DIN rail bracket 122 in this example. The DIN rail bracket 122 is integrally formed with a retaining element 124. The retaining element 124 is approximately L-shaped and has a first leg 126 and a second leg 128, which are oriented approximately perpendicular to each other. The DIN rail bracket 122 is integrally formed with the second leg 128 of the retaining element 124.

[0044] In the present example, a first, inner hook element 130 and a second, outer hook element 132 are integrally formed on the first leg 126. The distance between the first hook element 130 and the second leg 128 is chosen such that a metal rail 34 with a depth of approximately 15 millimeters can be clamped between the first hook element 130 and the second leg 128, thus enabling the component holder 120 to be attached to the metal rail 34 (see Fig. 16 ).

[0045] The first hook element 130 is designed as a cantilever and is set back slightly from the second, outer hook element 132. The cantilever 130 does not extend continuously over the entire area of ​​the component holder 120. Rather, the cantilever 130 has two gaps in the edge region of the component holder 120 (see in particular...). Fig. 19In the area of ​​these gaps, the hook bend 134 of a spring tongue 136 is present. The spring tongues 136 extend essentially over the entire area between the second leg 128 and the first hook element 130.

[0046] To be able to attach the component holder to a deeper metal rail 36 (see Figs. 20 and 21 The inner hook element 130 is set back a short distance compared to the second hook element 132. This allows the inner hook element 130, designed as a cantilever 130, to engage in the groove 138 present in a deeper metal rail 36 without the need to remove the cantilever 130. The spring tongue 136 is deflected backwards by the groove 138 of the metal rail 36 (see Fig. 23In some cases, the spring tongue 136 may break off. However, it is not necessary to intentionally remove the spring tongue 136, so this additional step can be omitted during the assembly of the component holder 120.

[0047] In this case, the outer hook element 132 can, with its bend 139 pointing towards the second leg 128, clamp around the edge of the metal rail 36, so that the metal rail 36 can be held clamped between the second leg 128 and the outer hook element 132.

[0048] In the present example, the second leg 128 of the retaining element 124 has a central opening 140. This central opening 140 can be used for a screw fastening (not shown here). The opening 140 thus serves as a fastening element for fixing the component holder 120 in the longitudinal direction 42 and in the transverse direction of the metal rail 34, 36.

[0049] Furthermore, in this example, two inwardly pointing locking pins 144 are integrally formed on the second leg 128. The locking pins 144 can engage in recesses 46 of the metal rail 34, 36, thus also enabling the component holder 120 to be fixed longitudinally 42 along the metal rail 34, 36. The locking pins 144 therefore also serve as fastening elements. In this example, the locking pins 144 are arranged such that the opening 40 aligns with a recess 46, 48 of the metal rail 34, 36 when the locking pins 144 engage in the recesses 46, 48. Therefore, both fastening options for the second leg 128 of the retaining element 124 can be used simultaneously.

[0050] The metal rail 34, 36 typically has two different recesses 46, 48. Most of the recesses 46 have a circular cross-section. At greater intervals, instead of the circular recesses 46, there are alternative recesses 48 with an approximately square cross-section. To enable the locking pins 144 to engage in both recesses 46, 48, the locking pins 144 have two different outer contours 146, 148 (see Fig. 16In the connection area of ​​the locking pin 144, the locking pin 144 has a first outer contour 146, which is approximately square or rectangular. This first outer contour 146 is adapted to the larger recesses 48 of the metal rail 34, 36, so that the locking pin 144 can be inserted into the recesses 48. Below the first outer contour 146 is a second, different outer contour 148 of the locking pin 144. This second outer contour 148 is approximately circular and can therefore be inserted into the recesses 46.

[0051] Since the recesses 46 are significantly smaller than the recesses 48, the locking pin 144 is formed on a spring-loaded tongue 150 in each case. The spring-loaded tongue 150 allows the locking pin 144 to be pushed upwards away from the metal rail 34, 36, so that its circular second outer contour 148 can engage in the smaller, round recesses 46 of the metal rail 34, 36.

[0052] To release the locking pins 144 from the recesses 46, 48 of the metal rail 34, 36 as planned and to remove the component holder 120 from the metal rail 34, 36, an actuating element 152 is integrally formed on the spring-loaded tongue 150 above the locking pin 144. In this example, the actuating element 152 is designed as a groove. A suitable tool, in particular a screwdriver, can be engaged in this groove 152. This allows the spring-loaded tongue 150 to be lifted slightly, so that the locking pin 144 is removed from the recess 46, 48.

[0053] In this example, the first leg 126 of the retaining element 124 has two inwardly pointing locking pins 154. The locking pins 154 are each located next to the spring-loaded tongues 136. The locking pins 154 can engage in lateral recesses 156 of the metal rail 34, 36, thus enabling the component holder 120 to be fixed longitudinally 42 along the metal rail 34, 36. The locking pins 154 therefore serve as an additional fastening element for the first leg 126 of the retaining element 124.

[0054] The DIN rail holder 122 has two lateral guide grooves 160, 162, in which one edge of a DIN rail can be positioned (see Figs. 18 and 19In the present example, one of the two lateral guide grooves 160 is stationary. The stationary guide groove 160 is not movable, so the DIN rail is first inserted into this stationary guide groove 160 with one edge. The other of the two guide grooves 162, however, has a movable locking hook 164. The locking lug 166 of the locking hook 164 forms the upper surface of the guide groove 162 in this case. To insert the DIN rail into the DIN rail holder 122, it is first inserted at an angle into the stationary guide groove 160 with one edge. The DIN rail is then guided from above past the locking lug 166 of the movable locking hook 164, deflecting the locking hook 164 accordingly. After the movable locking hook 164 snaps back into place, this edge of the DIN rail is also securely held in the guide groove 162.In this example, the locking lug 166 of the movable locking hook 164 has a convex outer contour 168. Such an outer contour 168 has the advantage that the locking hook 164 deflects more easily when sliding along the edge of the DIN rail. Therefore, less force is required to deflect the locking hook 164, thus significantly simplifying the installation of the DIN rail.
