Description

  The invention relates to an assembly device for assembling bus bars of a busbar, comprising fixing flanges which are provided with fixing holes and on which the bus bars can be screwed. As shown in document US Pat. 'other. However, this assembly device is not suitable for all possible assemblies of a busbar set, such as the T-branch, branches in offset planes, etc. The object of the invention is to create an assembly device for assembling bus bars of a busbar, which allows in a simple and universal way to carry out all types of bus bar diversions which are

  necessary for a busbar.

  According to the invention, this object is achieved by the fact that four fixing flanges form two fixing brackets which are interconnected in the area of the outer edge of their angle by a junction element so as to form a single piece, that the fixing flanges start from the joining element and extend in pairs in opposite directions, and that the fixing surfaces of the pairs of fixing flanges are each located in parallel planes, the planes of the pairs

  of fixing bnides being perpendicular to each other.

  By making the assembly element in this way, it is possible to assemble the bus bars by the front faces or the external longitudinal faces in different directions. This gives a busbar a

universal use.

  If, in accordance with another embodiment, it is provided that at least the fixing surfaces of a pair of fixing flanges are arranged in the same plane, then one obtains, at least in certain cases of application, a bypass in

  flush with the assembled bus bars.

  One embodiment makes it possible to obtain an optimal match between the bus bars and the assembly device by the fact that the bus bars have an essentially square section with a predefined side length, and that the fixing surfaces of the fixing flanges are also made square with the predefined side length, since in all application cases the fixing flanges are

  end flush with the faces of the bus bars facing each other.

  The fixing of the bus bars to the fixing flanges of the assembly element is facilitated and simplified by the fact that the bus bars are provided in the middle of each outer face with a longitudinal groove cn T in which can be inserted parts d assembly for T-grooves made with a corresponding T-section, that the assembly parts for T-grooves have in at least one front face a threaded housing and, at a distance from a front face corresponding to the predefined side length , a tapped hole orients transversely to the longitudinal direction of the longitudinal groove, that the distance between the tapped housing and the outside face of the busbar constitutes a predefined assembly distance, that the tapped hole is distant from the front face of the connecting piece for T-slot of a distance corresponding to half of 10 the predefined side length, that the fixing flanges are provided in the middle of their fixing surface with a fixing hole for a fixing screw which can be screwed into a tapped hole in an assembly part for a T-slot, and which the fixing flanges carry, at a distance from the free end edge of the fixing flange equivalent to the assembly distance and in the middle of the width of said fixing flange, an additional fixing hole for a fixing screw which can be screwed into a threaded housing with an assembly part for a T-slot. Consequently, it is not necessary to provide the bus bars with fixing holes,

  just put them to the desired length.

  If, in addition, it is intended that the mounting flanges are provided on the face opposite the mounting surface with tunnel-like recesses around the mounting holes and additional mounting holes, then the heads of the screws

  are embedded in the mounting flange.

  The connecting pieces for T-slots are perfectly immobilized in the longitudinal groove of the busbar when the connecting pieces for T-slots are provided with a slot extending to the threaded hole, which starts from a front face of the assembly piece for T-slot without threaded housing. The fixing screw spreads the parts of the assembly part to

  T-shaped groove in the area of the slot and immobilizes them against the walls of the groove.

  If the construction is such that the joining element has a section in the shape of a parallelogram, or the joining element has a rectangular section, then the fixing surfaces are each offset from one another in the perpendicular fixing planes of the pairs of fixing flanges of a

  distance previously defined by the junction element.

  For good current flow with low contact resistance, the

  assembly device is copper.

  The invention is described in more detail with the aid of exemplary embodiments shown in the drawings. The figures show: Fig. I seen in exploded view, an assembly device whose joining element has a section roughly in the shape of a parallelogram FIG. 2 seen in exploded view, an assembly device whose joining element has an approximately rectangular section; Fig. 3 perspective view, part of a busbar set with several different branches; and Fig. 4 top view, intersection with a bus bar above bars

omnibus already in place.

  As shown in fig. 1, an assembly device 20 according to the invention has four fixing flanges 21, 22, 27 and 28. The fixing flanges 21 and 22 form a first fixing bracket with their fixing surfaces A and B perpendicular to each other, and the fixing flanges 27 and 28 a second fixing bracket with their fixing surfaces C and D. The fixing brackets are connected together in the region of the outer edge of their angle by a junction element 50, so to form a single piece. The fixing flanges 21 and 27, as well as 22 and 28 are each located in fixing planes parallel to each other, knowing that the fixing planes of the fixing flanges 21 and 27 are perpendicular to the fixing planes of the fixing flanges 22 and 28. This is also the case in the example of

  production of an assembly device 20 according to FIG. 2.

  We see in fig. 2 that the fixing surfaces A and C of the fixing flanges 21 and 27 are offset with respect to each other by a distance c, while the fixing surfaces B and D of the fixing flanges 22 and 28 are offset from each other by a distance d. These offsets c and d are determined by the section of

  connecting elements 50 (fig. 1) and 51 (fig. 2) respectively.

  The bus bar 10 has an essentially square outer section with a predefined side length a. In the middle of all the outer faces of the busbar 10, a longitudinal T-shaped section groove 11 is formed, the longitudinal median plane of which is located at a distance a / 2 from the outer faces of the

  bus bar 10 which connects to it perpendicularly.

  In the longitudinal grooves 11 can be inserted assembly parts for T-grooves 60, the cross section of which corresponds to the cross section of the longitudinal grooves 11 of the bus bar 10 and which have a threaded bore 61 extending transversely to their longitudinal direction , for fixing screws 40, 41 and 42. The tapped hole 61 is accessible by the external face of the bus bar 10 which is associated with it and is distant from a front face of the assembly part for T-slot 60 a distance corresponding to half the length of side a. In addition, a threaded housing 63 for a fixing screw 43 is provided at least in this front face. The assembly piece for T-slot 60 is provided with a slot 62 extending from a front face, which extends to the threaded hole 61 and which defines clamping jaws, which lock in the longitudinal groove 11 when a fixing screw 40, 41 or 42 is screwed into the threaded bore 61 and thus immobilize the latter in the axial direction. The threaded housing 63 can also extend to the threaded hole 61, so that the longer fixing screw 43 can also spread the clamping jaws in the region of the slot 62. The longitudinal axis of the threaded housing 63 is distant from the external face which is associated with it by a distance b when the connecting piece for T-slot 60 is inserted in the

  longitudinal groove 11 of this outer face.

  The fixing surfaces A to D are square and have, like the bus bar 10, a side length a. In the middle of each fixing flange 21, 22, 27, and 28 sc there is a fixing hole 23, 24, 29 and 30 respectively for a fixing screw 40, 41 or 42, which coincides with the longitudinal central axis 12 of the bus bar 10, so that a front face of the bus bar 10 can be screwed onto each of the fixing flanges 21, 22, 27 or 28 of the assembly device 20. An additional fixing screw 43 can be screwed into a threaded housing 63 of an assembly piece for a T-slot 60 when using the fixing holes 25, 26, 31, and 32 formed in the fixing flanges 21, 22, 27 and 28, which are produced at a distance b from the free end edge and at a distance a / 2 from the lateral edges of the flanges

fastening 21, 22, 27 and 28.

  The fixing flanges 21, 22, 27 and 28 can have recesses on the faces opposite to the fixing surfaces A, B, C and D similar to tunnels 33, 34, 35 and 36 around the fixing holes 23, 24, 29 and 30, as well as 25, 26, 31 and 32, in which the heads of the fixing screws 40, 41, 42 and 43 can be

drowned.

  The fixing surfaces A and C and / or B and D on the junction elements 50 and 51 respectively of the assembly devices 20 according to FIGS. 1 and 2 can be

  arranged in the same plane, so that the offset c and / or d becomes zero.

  As shown by a busbar according to fig. 3, an assembly device according to FIG. 1 or 2 allows bus bars 10.1 to 10.6 to be derived in different directions. A 10.2 busbar may extend downwards from any location on a horizontal busbar 10 using an assembly device 20.1, the front face of the 10.1 busbar having relative to the rear face from the bus bar 10.2 an offset c. The front face of the busbar 10.1 is then screwed onto the fixing flange 21, the threaded bore 61 made in the assembly part for T-slot 60 located below being used for this purpose. On the fixing flange 28 of the assembly device 20. I is screwed the front face of the busbar 10.2, the fixing screw 43 being screwed into the tap housing 63 of the assembly piece for T-groove 6 (0 The fixing flange 22 of the assembly device 20.1 I can also be screwed onto the underside of the bus bar 10.1 and the fixing flange 27 of the assembly device 20. 1, onto the rear face of the bus bar 10.2, the threaded hole 61 in the assembly parts for associated T-slots (6) being used for this purpose. The assembly device 20.2 makes it possible to derive in the same way the bus bar 10. 3 oriented downwards. the rear face of the busbar 10.1, knowing that there is also the offset c between the rear face of the bar

  bus 10.1 and the front of the bus bar 10.3.

  The assembly device 20.3 makes it possible to fix to the busbar 10.3 extending vertically a busbar 10.4 which is derived therefrom horizontally, the front lace of the busbar 10.4 having an offset with respect to the left side of the busbar 10.3 c, since these faces are screwed onto the fixing surfaces A and C of the fixing flanges 21 and 27 of the assembly device

20.3.

  The assembly device 20.4 makes it possible to fix perpendicularly to the rear face of the busbar 10.1 the horizontal busbar 10.5, the assembly device 20.4 ending in flush with the front face of the busbar 10.1. The rear face of the bus bar 10.1 is offset by the distance c with respect to the front face of the bus bar 10.5, since these faces occupy the fixing flanges 21 and 27 with their fixing surfaces A and C. The face lower of the busbar 10.1 is offset by the distance d relative to the upper face of the busbar 10.5, since these faces are screwed onto the fixing flanges 22 and 28 of the assembly device 20.4. On the other front face of the bus bar 10.5 is fixed using the assembly device 20.5 a bus bar oriented perpendicularly downwards 10.6, the front faces of the two bus bars 10.5

  and 10.6 being screwed onto the fixing flanges 21 and 28 of the assembly device 20.5.

  The front face of the bus bar 10.5 therefore has relative to the front face of the bus bar 10.6 the offset c, and the underside of the bus bar

  ) 10.5, the offset d from the front face of the busbar 10.6.

  In fig. 4, the references 10.10, 10.1 1 and 10.12 designate the busbars oriented vertically in a plane of a three-phase busbar. An additional horizontally arranged bus bar 10.7 is added to this set of bus bars. The front face of this bus bar 10.7 is screwed onto the fixing flange 27 and its rear face onto the fixing flange 28 of the assembly device 20. 6, so that a bus bar 10.8 can be connected horizontally to the flanges 21 and 22 by being offset horizontally backwards or forwards from offset d and can cross the bus bars 10.) 10 to 10.12 without touching them. The assembly device 20.7 extends the intersection with respect to the bus bar 10.9, which is

  as for it again disposde in the plane of the three bus bars 10. 10 to 10.12.
