Definitions

  • the invention relates to a busbar system.
  • Busbars and busbar systems are basically known from the prior art. These are used in particular for electrical devices such as lights in order to supply them with electrical energy (current and/or voltage) and/or data.
  • the busbar usually extends along a longitudinal direction, for example on a ceiling, so that the devices connected to the busbar can be easily electrically connected to the busbar or to the electrical lines running in the busbar via a plug.
  • the power rail also offers the advantage that the lamp can also be mechanically attached to the power rail, for example to a support rail of the power rail.
  • a busbar is known in which electrical lines (electrical conductors) are integrated into contact webs of a busbar profile in order to be provided on two levels of different heights.
  • electrical lines electrical conductors
  • the manufacture of this conductor rail profile is complex, since in particular the electrical lines have to be provided laterally in the respective contact webs. Due to the fact that the electrical lines are accommodated laterally in the contact webs, the electrical lines are also relatively difficult to contact.
  • the present invention sets itself the task of providing a busbar and a busbar system provide that are particularly easier to produce and easier to electrically contact.
  • the invention relates to a busbar, having a busbar profile with a first and a second group (row) of grooves, the grooves of the first group (row) starting at a different depth than the grooves of the second group (row). from the side of the conductor rail profile via which the grooves are accessible to a bottom of the grooves.
  • a respective electrical line is accommodated in each of the grooves and is accessible via the respective groove for electrical contacting.
  • the electrical lines of the conductor rail profile can be provided at different levels of the conductor rail or the conductor rail profile simply by virtue of the grooves of different depths or bottoms of the grooves of different heights.
  • the electrical lines of the slots of the first group are thus provided laterally offset from one another in relation to the electrical lines of the slots of the second group.
  • the power rail is usually - that is, preferably - an elongate busbar with an elongate busbar profile with a direction of extension. This direction of extent is preferably rectilinear, but can also run differently.
  • the grooves of the first and the second group are preferably accessible from the same side of the busbar profile. This is particularly advantageous for simple electrical contacting of the electrical lines accommodated in the slots.
  • the conductor rail profile alternately has a groove from the first group and a groove from the second group.
  • a groove of the other group for example the first group
  • two adjacent grooves of one group for example the second group.
  • Such a nested configuration of the first and the second group allows the conductor rail to be of compact design.
  • the conductor rail profile can have at least eleven, preferably 15, grooves, and/or the first group preferably has at least five grooves and the second group preferably has at least six grooves. With the corresponding number of electrical lines, the conductor rail profile can therefore be designed with 11 poles or 15 poles.
  • the grooves of the first group have a greater depth than the grooves of the second group, starting from the side of the conductor rail profile via which the grooves are accessible, down to the bottom of the grooves.
  • the busbar profile preferably has a direction of extension, with the grooves of the first and second group extending in the direction of extension--that is, along or along the direction of extension.
  • the bus bar can be made compact.
  • the busbar, the busbar profile and/or the grooves of the first and the second group can be elongate. Elongated is understood here to mean that the respective length corresponds to a multiple of the respective width.
  • the respective electrical line preferably extends in each of the grooves in a plane which corresponds to the depth of the respective groove.
  • the respective electrical line can be accommodated on the bottom of the respective groove or can be arranged on or near the bottom.
  • the at least two electrical lines can be accommodated in the respective grooves in a detachable or non-detachable manner.
  • the respective electrical line is preferably in non-positive, positive and/or material-locking contact with the respective groove and/or with the bottom of the respective groove.
  • the electrical lines are or were preferably produced directly with the busbar profile, in particular injected at the same time.
  • the conductor rail can thus be produced particularly easily with the electrical lines.
  • the electrical lines are subsequently introduced into the respective grooves, preferably clipped or rolled in.
  • the busbar profile is preferably made of plastic.
  • the busbar particularly preferably the busbar profile, has a fastening means for non-positive and/or positive fastening of the busbar on or in a (light) mounting rail.
  • the mounting rail is part of a lamp housing or forms a lamp housing.
  • the fastening means can have at least one latching projection for engaging in a corresponding latching receptacle, in particular in one corresponding contour of the mounting rail, so that the busbar, preferably the busbar profile, can be attached to the mounting rail.
  • the invention relates to an (elongated) busbar system with a busbar and a plug holder for holding a plug electrically connected to the busbar.
  • the plug holder can cause already known plugs to be used for electrical tapping of the busbar, in particular for electrical tapping of the electrical line provided in the busbar at different levels; the plug holder can therefore serve as a kind of adapter so that an existing plug does not have to be structurally adapted to the busbar.
  • the busbar of the busbar system is, for example, the busbar described above.
  • the busbar can have: a busbar profile with grooves, a respective electrical line being accommodated in each of the grooves and being accessible via the respective groove for electrical contacting.
  • the bus bar can be designed like the bus bar described above, with the difference that the bus bar does not require the following: a division into a first and a second group of grooves, the grooves of the first group compared to the grooves of the second group have different depths, starting from the side of the conductor rail profile via which the grooves are accessible, down to a bottom of the grooves.
  • the connector holder has a (connector holder) attachment means for non-positive and/or positive attachment of the connector holder to the busbar.
  • the fastening means fastens the connector to the busbar in such a way that moving the connector holder relative to the busbar, in particular (only) along the (longitudinal) Extension direction or longitudinal axis of the busbar (that is, preferably along with respect to (the direction of extension) of the busbar) is possible.
  • a plug held by the plug holder and in electrical contact with the electrical lines can be moved along the busbar without interrupting the electrical connection between the busbar or electrical lines and the plug; During the movement of the plug holder relative to the busbar, the plug or its plug contacts then slide on the electrical lines.
  • the plug or a lamp connected to the plug since even after the plug holder or plug has been attached to the busbar, the position of the plug holder or plug - and thus, for example, also a connected electrical device such as a lamp - can be changed relative to the power rail.
  • the (connector holder) fastening means connects the connector holder or the connector to the busbar in a fixed manner, i.e. not movable with respect to all degrees of freedom.
  • the (plug holder) fastening means has at least one latching projection, which engages in a corresponding latching receptacle, in particular in a groove, in the busbar, preferably the busbar profile, so that the plug holder is fastened to the busbar (movable relative to the busbar).
  • the connector holder can thus be attached to the busbar in a particularly simple manner.
  • the connector holder has at least one elastic element, such as a spring element, which extends into the busbar, preferably into one of the grooves, particularly preferably into a groove of the group of grooves with a smaller depth, and into the busbar, preferably in the respective groove and / or on the respective electrical line is supported in such a way that the connector holder is biased relative to the busbar.
  • a certain inhibition between the connector holder and busbar can be brought about in order to position the connector holder (movable relative to the busbar) securely at a defined position along the busbar.
  • the plug holder preferably has at least one centering and/or guiding element for centering and/or guiding the plug holder relative to the busbar or the current-carrying profile.
  • the centering and/or guiding element is preferably a projection engaging in one of the grooves.
  • the grooves can thus be used at the same time for centering and/or guiding the connector holder relative to the busbar, which is consequently advantageous for compact and simple production of the elements required for centering and/or guiding.
  • the projection particularly preferably engages in a groove of the group of grooves with a greater depth. Due to the relatively large depth, a particularly good centering and/or guidance of the plug holder can be effected. Alternatively or additionally—in particular for particularly good centering and/or guidance of the plug holder—it is preferred that the spring element extends further from the plug holder than the spring element.
  • the plug holder has insertion openings for inserting plug contacts of a plug into the busbar, preferably into the grooves for contacting the respective electrical lines.
  • the insertion openings can guide the plug in such a way that it is automatically fastened to the plug holder, for example via the fastening means mentioned above.
  • the insertion openings are preferably formed as groups, for example corresponding to the groups of grooves, in the plug holder.
  • the insertion opening can be formed in rows (provided/distributed along the longitudinal direction), in particular as only two rows, in the plug holder.
  • the insertion openings are distributed not only in the width direction but also in the longitudinal direction of the connector holder, so that the connector holder can be made more compact particularly in terms of its width.
  • the insertion openings preferably each have insertion bevels.
  • the plug holder preferably has a (further plug holder) attachment means for non-positive and/or positive attachment of the plug holder to a mounting rail connected to the busbar.
  • the hold of the plug holder on the busbar can thus be improved.
  • the mechanical connection between the connector holder and busbar can be relieved by diverting the power flow to the mounting rail.
  • the (additional connector holder) fastening means can fasten the connector holder to the mounting rail in such a way that the connector holder can be moved relative to the mounting rail, in particular in the longitudinal direction of the mounting rail. This is particularly advantageous when the (plug) fastening means movably connects the plug holder to the busbar, as described above.
  • the support rail can thus also serve, for example, as a guide for the connector holder relative to the busbar.
  • the (additional connector holder) fastening means preferably has at least one latching projection which can engage in a corresponding latching receptacle, in particular in a corresponding contour, of the mounting rail in order to secure the connector holder on the mounting rail to fix.
  • the connector holder can thus be fastened to the mounting rail in a particularly simple manner, in particular in a movable manner.
  • the busbar and/or the plug holder has reverse polarity protection, which means that the plug holder can be plugged onto the busbar in only one orientation relative to a direction of attachment of the busbar for plugging the plug holder onto the busbar.
  • the push-on direction is generally the depth direction of the respective grooves and/or a direction perpendicular to the longitudinal direction of the busbar.
  • the (mechanical) protection against reverse polarity is therefore structurally avoided in that a user of the busbar system connects the plug holder to the busbar in the wrong orientation, in which the plug and the busbar would be electrically connected to one another with the wrong polarity.
  • the reverse polarity protection thus offers a so-called poka-yoke solution.
  • the reverse polarity protection has a first projection on the side of the busbar and a second projection on the side of the connector holder, the projections being provided in such a way that the projections collide with one another (are in the way) in at least one orientation of the connector holder relative to the direction in which the busbar is attached. , to prevent the connector holder from being attached to the busbar. Therefore, if the projections collide, the previously mentioned (plug holder) fastening means, in particular, cannot fasten the plug holder on the busbar. This in particular because the locking projection cannot engage in the corresponding locking receptacle due to the distance caused by the projections colliding. In this way, the reverse polarity protection can be provided structurally in a particularly simple manner.
  • the busbar system preferably also has a plug for making electrical contact with electrical lines running in the busbar, for example the electrical lines, with the plug being held on the busbar by the plug holder.
  • a simple electrical connection between the power rail and a lamp can be provided via the plug.
  • the plug can be designed to make electrical contact with the electrical lines from a single defined side of the busbar. Thus, all electrical lines can be easily electrically contacted through the plug in only one plug-in direction, which is, for example, perpendicular to the only defined side (for example the plug-on direction mentioned above).
  • the plug preferably has plug contacts for making electrical contact with the electrical lines.
  • the plug can have a corresponding number of plug contacts, which are preferably provided detachably with the plug.
  • the plug contacts preferably extend away from the plug with different lengths in order to make electrical contact with the electrical lines provided in the grooves that are preferably of different depths.
  • the plug contacts can thus be provided on a common level, for example in a common housing part of the plug, as a result of which a compact plug can be provided.
  • the plug and the plug holder are preferably non-detachably connected to one another, in particular formed integrally with one another.
  • the plug and the plug holder can also be connected to one another in a detachable manner, preferably via corresponding connecting means such as, for example, via a snap-in connecting means.
  • the connecting means are preferably designed with a support rail connected to the power rail in power and/or positive contact, for example in a latching contact to come.
  • the detachable connection between the connector and the connector holder is particularly advantageous when existing/existing connectors are to be used for electrical contacting with the conductor rail and mechanical retention by the connector holder.

The restoring force of the elastic elements 22 can thus be summed up in order to bring about an even greater inhibition between the busbar 1 and the connector holder 20 .
  • the plug holder 20 preferably has at least one centering and/or guide element 23 for (leading) centering or guiding of the plug holder 20 relative to the busbar 1 or to the current-carrying profile 2 .

  • the projection is a projection 231 which extends into a groove of the first group 4 of grooves, ie the group of grooves with a greater depth, or engages in the respective groove.
  • the projection 231 can extend further away from the plug holder 20 than the elastic element or spring element 22, preferably so far that the projection 231 is in contact with the groove in the respective first group 4 recorded electrical line 7 comes into (non-conductive) contact.
  • the centering and/or guiding element 23 can have a further projection 232, which extends into a groove of the first group 4, but preferably extends less far away than the elastic element or spring element 22; the further projection 232 is therefore preferably shorter than the projection 231. It is preferred if the plug holder 20 has at least two projections 231 and/or at least two, preferably three, projections 232 which (only) engage in grooves of the first group 4.
  • the respective projection 231 or 232 is preferably provided between two elastic elements 22 .

  • Figure 4d an example of an orientation of the connector holder 20 relative to the busbar 1 is shown, in which the connector holder 20 cannot be plugged onto the busbar 1 or the busbar profile 2 . It can be seen that in this orientation the fastening means 21 of the plug holder 20 cannot engage with the busbar 1 because of the reverse polarity protection 25 in order to fasten the plug holder 20 to the busbar 1 .
  • a fitter will recognize this and rotate the plug holder 20 accordingly, in particular by 180° around the plug-on direction, so that the plug holder 20 can be attached to the busbar 1 via the attachment means 21 .

  • the lead 252 can be formed laterally in the plug holder 20, for example integrally with the locking projection 211.
  • the projection 252 preferably extends in an area next to the locking projection 32, which corresponds to the area in which the projection 251 is provided next to the locking projection 31, but with the difference that that there is no protrusion for protrusion 252 to encounter; the fastening means 21 can thus come into engagement with the conductor rail 1 or the conductor rail profile 2 .
  • the plug holder 20 preferably has a (further) fastening means 26 for non-positive and/or positive fastening of the plug holder 20 to a mounting rail 10 connected to the busbar 1; this connected state between fasteners 26 and support rail 10 is, for example, in the Figure 8b clearly visible.
  • the fastening means 26 fastens the connector holder 20 to the mounting rail 10, preferably in such a way that the connector holder 20 can be moved relative to the mounting rail 10, ie in particular in the longitudinal direction.

  • the groove 14 is designed essentially corresponding to the groove 13 so that what was said with regard to the groove 13 applies analogously to the further groove 14 .

  • the plug contacts 41 are preferably designed to make electrical contact with the electrical lines 7 provided on levels of different heights due to the grooves of different depths. This is preferably done by the plug contacts 41 extending away from the plug 40 for different lengths; the plug contacts 41 thus have longer plug contacts 411 (for the deeper grooves or lines) and shorter plug contacts 412 (for the higher grooves or lines).
  • the plug contacts 411, 412 are preferably provided in accordance with the groups 241, 242 at insertion openings in the plug 40, for example in groups and/or as rows (arranged/distributed in the longitudinal direction of the busbar system 100), preferably (only) two rows.
