Description

TECHNICAL FIELD

[0001] The present application relates to a support rail fixing device for fixing a support rail equipped with components to a wall, for example a wall of a switchgear cabinet. The present application also relates to an assembly and a switchgear cabinet having such an assembly. BACKGROUND

[0002] Support rails can be designed as elongated U-shaped or C-shaped profiles and are used to accommodate a large number of components, in particular connection terminals, such as terminal blocks. These components can be installed in the switchgear cabinet by means of the support rail. The support rail usually has a plurality of openings through which the support rail can be bolted to the wall of the switchgear cabinet. Since the support rail cannot be accessed by the bolts when it is equipped with components, the support rail must first be fixed to the switchgear cabinet by means of the bolts and can only be equipped with components after the support rail has been fixed or assembled to the wall of the switchgear cabinet. Therefore, it is not possible to install a support rail in the switchgear cabinet which is prefabricated and equipped with components. As a result, automated assembly of the support rail is also not possible. Therefore, the assembly effort for equipping the switchgear cabinet with components and support rails is very high. Furthermore, for the connection of the shielding layer or shielding braid of a cable to one of the components, a separate support block is usually required to accommodate the terminal, wherein this support block must also be fixed to the support rail, thereby further increasing the assembly effort. SUMMARY

[0003] It is an object of the present application to provide a support rail fixing device, an assembly and a switchgear cabinet which reduce the assembly effort.

[0004] According to the application, the object is achieved by the features of the independent claims. Suitable design embodiments and advantageous extensions of the application are given in the dependent claims.

[0005] The support rail fixing device according to the application is characterized in that it has a fixing device having at least two fixing elements for accommodating a support rail, a rail assembly connected to the at least two fixing elements and at least one terminal arranged on the rail assembly.

[0006] According to the application, the fixing of the terminal is now achieved by the fixing elements of the fixing device, which is also used to fix the support rail to the wall or mounting plate. An additional component to be fixed to the support rail for accommodating the terminal is therefore no longer required. The number of components to be assembled can thereby be reduced, and the assembly effort can also be reduced. In the state already assembled, the support rail is fixed to the wall by the fixing elements of the fixing device, so that the support rail can be indirectly mounted to the wall. These fixing elements can be connected with the rail assembly on which the terminals are arranged, so that the rail assembly can be in direct contact with the fixing elements of the fixing device. The fixing elements can each have an accommodating contour, by means of which a form-fit and / or force-fit connection of the fixing elements to the rail assembly is achieved. The terminals are indirectly fixed to the fixing elements by means of the rail assembly. The terminals can be, for example, shielding terminals for clamping the shielding of a cable connected to the assembly, feed terminals or connection terminals. Other types of terminals are also possible. The components can be, for example, junction boxes, controls, power supplies and the like, wherein different types of components can also be arranged on the support rail, in particular clipped thereon.

[0007] The rail assembly preferably has at least two holding rails, wherein one of the at least two holding rails can be assigned to each fixing element and wherein the rail assembly can have a busbar connected to the at least two holding rails, wherein at least one terminal can be fixed to the busbar. The rail assembly therefore preferably comprises a plurality of holding rails, along which the busbar can extend, wherein the terminals are arranged on the busbar, for example in order to clamp and connect conductors or the shielding of a cable to the busbar. The number of holding rails can correspond, for example, to the number of fixing elements of the fixing device, so that one fixing rail can be assigned to each fixing element. The rail assembly can be directly connected and thereby fixed to the fixing elements by means of the holding rails.

[0008] The at least two holding rails are preferably releasably fixed on the at least two fixing elements. Each fixing element can have a receiving contour by which one of the holding rails can be received on the fixing element, respectively. The receiving contour can be designed, for example, in the form of a recess, in particular a slot-shaped recess, into which one of the holding rails can be inserted or pushed. The form-fit connection between one of the fixing elements and one of the holding rails can be made by means of the receiving contour. Furthermore, the holding rails can be connected to the respective fixing element in a force-fit manner. The force-fit connection can be realized by means of a fixing mechanism which can preferably also be used at the same time for fixing the fixing elements of the fixing device to the wall. Thus, the fixing mechanism can form a force-fit connection between one fixing element of the fixing device, the holding rail and the wall, respectively. The fixing mechanism can be, for example, a screw connection. Thus, the holding rails can also be fixed to the wall by means of the fixing mechanism. The fixing mechanism can be guided through the respective fixing element of the fixing device and through the holding rail in order to be fixed to the wall subsequently, so that the fixing elements of the fixing device and the respective holding rail of the rail assembly can be fixed to the wall at the same time.

[0009] The at least two holding rails can each be formed in the form of an angle rail, in particular in the form of an L-shaped angle rail. By forming the holding rails each in the form of an angle rail, a quick and easy assembly of the holding rails on the respective fixing element of the fixing device and of the busbar on the holding rail is achieved. The angle rail preferably has two rail arms which are preferably arranged at right angles to each other. The holding rail can be fixed on the first rail arm to the respective fixing element of the fixing device and the busbar and thus the terminal can be fixed on the second rail arm to the holding rail.

[0010] In order to facilitate the mounting of the busbar on the holding rail, a connecting element can be provided on each holding rail by means of which the busbar can be fixed on the respective holding rail. The connecting element enables the indirect fixing of the busbar on the holding rail, so that the holding rail itself does not necessarily have a specially designed receiving portion for the busbar. The connecting element can be fixed to the respective holding rail preferably detachably. For example, the connecting element can be fixed on the holding rail by means of a screw connection. The connecting element is preferably fixed on the holding rail at a distance from the respective fixing element of the fixing device.

[0011] The connecting element can be U-shaped and have two opposite flanks, respectively, which each have a through-opening through which the busbar can extend in the fixed state. The connecting element can be designed as a punched and bent sheet metal. The busbar can be pushed through the through-openings of the two flanks of the connecting element in order to receive and fix the busbar on the connecting element. In order to form the U-shape, the connecting element can have a bottom wall by means of which the two flanks are connected to each other. The connecting element can be fixed to the holding rail by means of the bottom wall.

[0012] Each fixing element of the fixing device can have a wall fixing section for fixing the fixing element to the wall and a support rail fixing section for fixing the fixing element to the support rail. In the state in which the fixing element is fixed to the support rail, the support rail fixing section can at least partially pass through an opening formed on the support rail. The support rail section preferably has a rear catch into which a section of the support rail can be inserted in the fixed state. In order to fix the support rail to the wall, in particular to the wall of a switchgear cabinet, a fixing device is now provided which has at least two fixing elements, wherein the fixing elements can first be fixed to the wall, which can also be a mounting plate, for example, and a pre-assembled support rail with components is then fixed to the fixing elements and thereby to the wall. The support rail can be pushed into the fixing elements fixed to the wall, so that the support rail can be held and fixed to the wall by being pushed into the fixing elements of the fixing device. There is no longer a need to fix further fixing means, for example a plurality of screws, to the support rail in order to fix the support rail to the wall. This leads to a significant simplification of the installation of the support rail on the wall. The support rail can be screwed directly to the wall, for example by means of a locking element, such as a screw, only at the end sections of the support rail, where no components are caught on the support rail, in order to be able to prevent the support rail from slipping out of the rear catches of the fixing elements accidentally. The fixing elements have two sections, a support rail fixing section and a wall fixing section. The support rail fixing section is formed directly adjacent to the wall fixing section. The components are caught on the support rail in the region of the top side of the support rail. The support rail is mounted on the wall by means of the bottom side of the support rail, which is opposite the top side, on which no components are caught. Through this bottom side, the fixing elements guide with their support rail fixing sections through the openings of the support rail, so that in the fixed state the fixing elements project with their support rail fixing sections at least partially through the openings of the support rail. Along the length of the support rail, it preferably has a plurality of such openings, in each of which such a fixing element can be arranged in order to fix the support rail to the wall. The openings on the support rail are preferably each formed elongated, so that their length is greater than their width. Along its length, the support rail fixing section can have a rear catch into which a section of the support rail adjacent to the opening can be inserted during assembly, so that the support rail can engage in the fixed state with the rear catch and the support rail can be held on the respective fixing element of the fixing device by means of the rear catch. The support rail can thereby be held and fixed on the fixing elements of the fixing device and thereby on the wall by means of a pure form-fit connection. By means of such a fixing device, a support rail which has already been assembled with components, a so-called pre-assembled support rail, can be quickly and easily fixed to the wall and thus with little installation effort.

[0013] The rear engagement portion can be designed in the form of a recess formed on the outer circumferential surface of the support rail fixing section. The support rail fixing section can have a cylindrical and thereby elongated shape, which can have a circular or oval cross section, for example. The recess can be formed on the outer circumferential surface of this cylindrical shape. The recess can be formed in the form of a notch on the outer circumferential surface of the support rail fixing section. From the outer circumferential surface, the recess extends in the direction of the central axis of the support rail fixing section.

[0014] The rear engagement portion, and thereby the recess, can taper from the outer circumferential surface of the support rail fixing section in the direction of the central axis of the support rail fixing section. By tapering, the section of the support rail can be purposefully introduced into the rear engagement portion. Furthermore, the section of the support rail can be introduced into the rear engagement portion simply.

[0015] The rear engagement portion, and thereby the recess, can be delimited by a first wall surface and a second wall surface opposite the first wall surface, wherein the first wall surface can have a ramped shape. By the ramped shape, the first wall surface can form an inclined surface. In contrast, the second wall surface preferably does not have a ramped shape. The second wall surface preferably extends in a horizontal plane, which extends transversely to the central axis of the support rail fixing section. The first wall surface can extend inclined to the second wall surface, for example, at an angle of between 30° and 70°, preferably between 40° and 60°. By the ramped shape, tolerances of the support rail can be compensated. Furthermore, a support rail having different material thicknesses can thereby be fixed on the fixing element of the fixing device. Furthermore, a virtually gap-free connection between the fixing element and the support rail, and thereby between the fixing device and the support rail, can thereby be achieved.

[0016] The support rail fixing section is preferably formed in one piece with the wall fixing section. Thus, the entire fixing element is preferably manufactured as one piece.

[0017] Furthermore, the fixing device can have a locking element in addition to the fixing element. The locking element is preferably arranged separately and thereby at a distance from the fixing element. By means of the locking element, the support rail can be prevented from unintentionally slipping out of or coming loose from the fixing element of the fixing device. The locking element can be fixed directly on the wall or directly on the support rail. The locking element is preferably arranged at an end of the support rail at which no parts or the like are engaged on the support rail. For example, the locking element can be a bolt. However, the locking element can also have the same shape as the fixing element, for example. The locking element formed in the same shape as the fixing element can then be fixed on the wall and on the support rail, for example, 180° rotated relative to the actual fixing element, in order to be able to form a blocking action which prevents the support rail from being pushed or slipped.

[0018] Each fixing element can have two centering ribs extending parallel to each other for orienting the support rail on the fixing element. The centering ribs can be formed on a wall fixing section of the fixing element. The centering ribs can be oriented in such a way that they can extend along the length of the support rail. The two centering ribs formed on the fixing element can be spaced apart from each other in such a way that the support rail can be accommodated between the two centering ribs. By means of the two centering ribs, the wall fixing section of the fixing element can form a U-shaped profile in cross section. The wall fixing section can be formed in the form of a flange, on which the two centering ribs can be molded.

[0019] Furthermore, the object according to the application is achieved by means of an assembly having a support rail and a support rail fixing device designed and further expanded as described above, wherein the support rail is fixed to a wall by means of the support rail fixing device in order to hold the support rail on the wall. Preferably, a plurality of fixing elements of the fixing device can be arranged along the length of the support rail, so that the support rail can be fixed to the wall with high stability and high reliability. The fixing elements of the fixing device arranged along the length of the support rail are preferably arranged spaced apart from each other.

[0020] Furthermore, the object according to the application is achieved by means of a switchgear having at least one previously described, formed and further expanded assembly fixed on a wall of the switchgear. BRIEF DESCRIPTION OF DRAWINGS

[0029] Figures 1 to 6 A support rail 200 equipped with components 300 is shown mounted on a wall 400 by means of a support rail fixture 100.

[0030] The support rail fixture 100 has a fixture 110 for fixing the support rail 200 on the wall 400 and a rail assembly 150 for mounting one or more terminals 170.

[0031] The fixture 110 has two fixture elements 111 here, which are each fixed on the wall 400 at a distance from one another.

[0032] The fixture elements 111 each have a wall fixing section 112, by means of which the fixture elements 111 can be fixed on the wall 400. In addition, each fixture element 111 has a support rail fixing section 113, by means of which the fixture elements 111 can be fixed on the support rail 200. The support rail fixing section 113 directly adjoins the wall fixing section 112. The support rail fixing section 113 is formed in one piece with the wall fixing section 112. The support rail fixing section 113 projects from the wall fixing section 112. The cross-sectional area of the support rail fixing section 113 is significantly smaller than that of the wall fixing section 112.

[0033] A rear catch 114 is formed on the support rail fixing section 113, into which a section 210 of the support rail 200 for fixing the support rail 200 to the fixture elements 111 can be inserted. The rear catch 114 is present as an undercut. The rear catch 114 is formed in the form of a recess, which is formed on the outer circumferential surface of the support rail fixing section 113. The recess and thus the rear catch 114 extend from the outer circumferential surface of the support rail fixing section 113 in the direction of the central axis of the support rail fixing section 113. In the design shown, the rear catch 114 extends into the support rail fixing section 113 to such an extent that the rear catch 114 extends all the way to the central axis of the support rail fixing section 113.

[0034] The recess forming the rear catch 114 is shaped such that it tapers in the direction of the central axis of the support rail fixing section 113 starting from the outer peripheral surface of the support rail fixing section 113. This tapering is achieved by one of the two wall surfaces 115, 116 delimiting the recess or the rear catch 114 having a ramped shape. The first wall surface 115 has a ramped shape, whereas the second wall surface 116 extends in a horizontal plane. The horizontal plane extends transversely to the central axis. By virtue of the ramped shape, the first wall surface 115 is designed to extend obliquely such that the first wall surface 115 extends at an angle of preferably between 30° and 60° with respect to the second wall surface 116.

[0035] The wall fixing section 112 adjoins the second wall surface 116 or the wall surface 116 can already be formed by the wall fixing section 112.

[0036] The second wall surface 116 forms a flat support surface for the section 210 of the support rail 200.

[0037] The wall fixing section 112 is in the form of a flange. By virtue of its flange shape, the wall fixing section 112 forms a support surface for the support rail 200 and the wall 400.

[0038] An opening 117 is formed in the wall fixing section 112, into which a fixing means 118, for example a screw connection bolt, can be inserted in order to fix the fixing element 111 to the wall 400. The wall 400 in turn has an opening 410 for each fixing element 111, into which the fixing means 118 of the fixing element 111 can be fixed, in particular screwed.

[0039] The fixing element 111 is also connected with a rail assembly 150. The rail assembly 150 has a plurality of retaining rails 152. In the design variant shown here, one retaining rail 152 is assigned to each fixing element 111.

[0040] An accommodation profile 119 for accommodating the retaining rail 152 is formed on the wall fixing section 112 of the fixing element 111. The accommodation profile 119 is formed on the bottom side 120 of the wall fixing section 112 which points in the direction of the wall 400. By means of this bottom side 120, the wall fixing section 112 and thus the fixing element 111 lies flat against the wall 400 in the installed state on the wall 400. The accommodation profile 119 is designed in the form of a trough-shaped recess. The accommodation profile 119 extends over the entire width of the wall fixing section 112 and thus of the fixing element 111.

[0041] In the assembled state, the retaining rail 152 is inserted or pushed into the receiving profile 119 of the fixing element 111, then the retaining rail 152 is connected with the fixing element 111 by guiding the fixing means 118 through the opening 117, and in this connected state the fixing element 111 is fixed with the retaining rail 152 on the wall 400 by the fixing means 118, as shown in Figure 1 In the assembled state, the fixing means 118 thus extends through the fixing element 111 and the retaining rail 152.

[0042] The retaining rail 152 is detachably fixed on the fixing element 111 by the receiving profile 119 and the fixing means 118.

[0043] The receiving profile 119 is designed such that in the pushed-in or inserted state the retaining rail 152 is flush with the bottom side 120 of the wall fixing section 112, so that the retaining rail 152 in the mounted state lies flat against the wall 400 like the bottom side 120 of the wall fixing section 112 of the fixing element 111.

[0044] The retaining rail 152 is formed in the form of an L-shaped angle rail, respectively. By being formed as an angle rail, the retaining rail 152 has a first rail arm 153 and a second rail arm 154. The first rail arm 153 extends at a right angle to the second rail arm 154. The retaining rail 152 is fixed on the fixing element 111 and the wall 400 on the first rail arm 153. The busbar 155 of the rail assembly 150 is fixed on the retaining rail 152 on the second rail arm 154.

[0045] Figure 2 The assembled state of the retaining rail 152 and the fixing element 111 on the wall 400 is shown.

[0046] If the retaining rail 152 of the rail assembly 150 and the fixing element 111 of the fixing device 110 are fixed on the wall 400, the support rail 200 with the component 300 is fixed on the fixing element 111 of the fixing device 110. For a better understanding, Figure 2 The support rail 200 is shown without the component 300 engaged thereon.

[0047] The support rail 200 is thus fixed on the fixing element 111 of the fixing device 110, which is already fixed on the wall 400. The support rail 200 is placed on the fixing element 111 here such that the support rail fixing sections 113 pass through the openings 211 formed on the support rail 200, respectively. At this point, the support rail fixing sections 113 are still spaced apart from the section 210 of the support rail 200, through which the support rail 200 is actually fixed on the fixing element 111.

[0048] To reach the final fixed state, the support rail 200 is moved in a pushing movement V so that the section 210 formed by the abutment opening 211 of the support rail 200 is pushed into the rear catch 114 of the support rail fixing section 113 of the fixing element 111. The inserted state is shown in Figure 2 In the case of a plurality of fixing elements 111, the support rail 200 is pushed with the respective sections 210 of the support rail 200 simultaneously into the rear catches 114 of the respective fixing elements 111.

[0049] In addition to the two fixing elements 111 shown here, the fixing device 110 also has a locking element 121. The locking element 121 is provided in the form of an additional component to the fixing elements 111. The support rail 200 can be fixed to the wall 400 at the end section 214 of the support rail 200 by means of the locking element 121, so that an unintentional slipping out of the support rail 200 from the rear catch 114 of the fixing element 111 can be prevented. The locking element 121 passes through an opening 216 on the end section 214 of the support rail 200. Unlike the opening 211, this opening 216 is not designed as an elongated hole here.

[0050] The locking element 121, like the fixing element 111, has a support rail fixing section 122 and a wall fixing section 123. The support rail fixing section 122 has a rear catch 124 into which a portion of the support rail 200 can be inserted, for example as shown in Figure 3 The rear catch 124 is present as an undercut. The rear catch 124 is formed in the form of a recess which is formed on the outer peripheral surface of the support rail fixing section 122. The recess and thus the rear catch 124 are formed here with the same shape as the recess and the rear catch 114 of the fixing element 111. The recess and thus the rear catch 124 taper in the direction of the central axis of the support rail fixing section 122.

[0051] The wall fixing section 123 is also designed here in the form of a flange in which an opening 125 is formed in which a fixing means 126 in the form of a threaded connection is arranged in order to fix the locking element 121 with its wall fixing section 123 to the wall 400.

[0052] The support rail 200 pushes with its end section 214 into the rear catch 124 of the support rail fixing section 122 of the locking element 121. This takes place in the region of the opening 216 on the end section 214 of the support rail 200. The opening 216 is formed open here so that the opening 216 has a U-shape. By the formation of the opening 216 open on one side, the support rail fixing section 122 of the locking element 121 can be pushed into the opening 216 until the support rail 200 sits in the rear catch 124 and is thus locked to the rear catch 124.

[0053] The locking element 121 is thus formed in the same shape as the fixing element 111. The support rail fixing section 122 of the locking element 121 is identical in shape to the support rail fixing section 113 of the fixing element 111. The wall fixing section 123 of the locking element 121 is also formed in the same shape as the wall fixing section 112 of the fixing element 111.

[0054] In order to achieve the locking effect of the locking element 121, the locking element 121 is arranged rotated by 180° relative to the identically shaped fixing element 111.

[0055] The wall fixing section 112 of the fixing element 111, which is formed as a flange, and the wall fixing section 123 of the locking element 121 are U-shaped in cross section, so that the support rail 200 can be pushed into the U-shaped cross section of the wall fixing sections 112, 123, as shown in Figure 3 In order to form the U-shape, the wall fixing sections 112, 123 each have two centering ribs 127, 128 arranged parallel to each other on the side thereof which points in the direction of the support rail 200, between which the support rail 200 can be inserted, so that lateral slipping or tilting of the support rail 200 on the flange-shaped wall fixing sections 112, 123 can be prevented.

[0056] After the support rail 200, which is fitted with the component 300, has been fixed to the fixing device 110 by placing the support rail 200 on the fixing device 110 and moving the support rail 200 in the direction indicated by the arrow V, the shielding layer or shielding braid of a cable which is inserted into the component 300, not shown here, can be fixed or clamped to the terminal 170, which is a shielding terminal here, for example, so that the shielding layer can be clamped to the busbar 155.

[0057] As shown in Figure 5 and Figure 6 The busbar 155 extends parallel to the length of the support rail 200. The busbar 155 is fixed to the holding rail 152 by means of a connecting element 156. One connecting element 156 is arranged on each holding rail 152. The connecting elements 156 are fixed to the second rail arm 154 of the holding rail 152, respectively. The fixing is effected here by means of a screw connection 157, so that the connecting elements 156 can be detachably screwed to the holding rail 152.

[0058] The connecting elements 156 each have a U-shape with two flanks 158, 159 which extend parallel to one another and a bottom wall 160 which is formed between the two flanks 158, 159. The bottom wall 160 is arranged at right angles to the two flanks 158, 159. The connecting elements 156 are fixed to the holding rail 152 by means of the bottom wall 160 by extending the screw connections 157 through the bottom wall 160. In the fixed state, the connecting elements 156 each lie with their bottom wall 160 flat on the holding rail 152 or the second rail arm 154 of the holding rail 152.

[0059] The flanks 158, 159 each have a through-opening 161, 162 for the busbar 155 in order to hold the busbar 155 on the connecting element 156. The through-openings 161, 162 of the flanks 158, 159 or of the connecting element 156 are arranged or oriented in alignment with one another.
