The housing 104 is further pressed in the direction of the line holder 134 and thereby the housing cover 119 is displaced in the direction of the housing 104. Thus, the current-carrying elements 127 come out of the protective elements 139 and stand over the

Protective elements 139 via. The current-carrying elements 127 come into contact with the previously selected line 138.

FIG. 8 shows one side of the current tap assembly 100 opposite the side shown in FIG. The third pantograph 108 and the fourth pantograph 109 are accessible from this side, for example. For example, the third pantograph 108 and the fourth pantograph 109 are immovable relative to one another. The third current collector 108 and the fourth current collector 109 are in particular displaceable relative to the housing 104 along the first direction 111. Thus, for example, a data line or signal line is selectable from the lines 138 to which the third current collector 108 is connected. By fixing the two current collectors 108 and 109 to one another, the line 138 is thus also predetermined, with which the fourth current collector 109 is connected. There may be further pantographs 148 formed

for example, a contact with the ground potential

realize. The further current collector 148 is according to

Embodiment identical to the other pantographs 106 to 109. According to further embodiments, the further current collector 148 is formed differently.

FIG. 9 shows the current tap arrangement 100 without

Housing cover 119. The housing 104 has a spring receptacle 149, in which a spring can be arranged. The spring urges the housing cover 109 in the second direction 112 away from the housing 104.

In the housing 104, a housing insert 105 is arranged. The housing insert 105 is mechanical with the first

Pantograph 106 and the second pantograph 107th

coupled. The housing insert 105 is immovably coupled to the housing 104 in a first state relative to the housing 104. In a second state is the housing insert

105 along the first direction 111 relative to the housing 104 slidably. The first current collector 106 is displaceable in the first state relative to the housing insert 105 along the first direction 111. Thus, in the first state by means of the shifting, a selection of the associated line 138 to the first current collector 106 is possible. The second current collector 107 is immovably fixed to the housing insert 105. Thus, the second current collector 107 in the first state is associated with one of the lines 138, independently of the first one

Pantograph 106 is moved. In a second state, the first pantograph 106 couples with the housing insert 105 such that the first pantograph

106 is only together with the housing insert 105 relative to the housing 104 slidably. Thus, in the second state, the first current collector 106 and the second current collector 107 are immovable with respect to each other

Housing insert 105 connected. The first pantograph 106 and the second pantograph 107 are common with the

Housing insert 105 relative to the housing 104 along the first direction, to move both for the first

Pantograph 106 as well as for the second pantograph 107 to make a line selection of the lines 138. In the housing 104, a further housing insert 118 is arranged. The third pantograph 108 and the fourth pantograph 109 are connected to the further housing insert 118. The third pantograph 108 and the fourth

Current collector 109, for example, fixed relative to each other immovably to the other housing insert 118. The third current collector 108 and the fourth current collector 109, together with the further housing insert 118, are displaceable relative to the housing 104 along the first direction 111. A displacement of the further housing insert 118 serves for line selection for the third current collector 108 and the fourth current collector 109.

Other types of release of displacements and the coupling of displacements of the individual pantographs 106 to 109 are possible.

FIG. 10 shows the housing 104 in accordance with FIG

 Embodiment. The housing 104 has a holding element 110. The holding member 110 is a kind of

Snap hook springy trained. In particular, that is

 Retaining element along the second direction 112 on one side movable.

Figures 11 and 12 show the housing insert 105 according to an embodiment. The housing insert 105 has a recess 150 corresponding to the retaining element 111. If the holding element 110 is arranged at least partially in the recess 150, the holding element 110 blocks a movement of the housing insert 105 relative to the housing 104 by a stop of the retaining element 110 with the boundary walls of the recess 150. If the retaining element 110 from a

Rest position is deflected and is no longer disposed in the recess 150, the movement of the housing insert 105 is released relative to the housing 104 along the first direction 111.

The housing insert 105 has a guide 151. The

Guide 151 is for example in the manner of a web

trained and set up the movement of the

Housing insert 105 relative to the housing 104 along the first direction 111 to lead. The housing insert 105 has a first receptacle 152 for the first current collector 106. The housing insert 105 has a second receptacle 153 for the second current collector 107. The first receptacle 152 is designed such that the first current collector 106 is fixed immovably along the second direction 112 and the third direction 113 relative to the housing insert 105 on the housing insert. Along the first direction 111, a movement of the first current collector 106 relative to the housing insert 105 is made possible by the shape of the first receptacle 152.

The second receptacle 153 is designed such that the second current collector 107 is firmly connected to the housing insert 105. The housing insert 105 has a pickup holder 115. The pickup bracket 115 is resiliently formed along the second direction 112. The pickup bracket 115 is configured to resist movement of the first one Stromabnehmers 106 along the first direction to act. The first receptacle 152 has at its end facing the second receptacle 153 along the first direction one end

Stop 116 on. The pickup bracket 115 and the stopper 116 are positioned relative to each other so that the first pantograph 106 can be held therebetween and fixed relative to the housing insert 105. Movement in the first direction 111 is blocked by the stop 116. The pickup holder 115 forms a

Resistance to movement against the first direction 111 from. In particular, a resistance between the

Housing insert 105 and the housing 104 when moving the housing insert 105 relative to the housing 104 is less than the resistance which is acted upon by the pickup holder 115. Thus, a displacement of the housing insert 105 together with the first pantograph 106 and the second pantograph 107 is possible when the first pantograph 106 is held by the pickup bracket 115 and the stopper 116. Only when the housing insert 105 again comes into engagement with the holding element 110, the resistance to the movement of the housing insert 105 is greater and thus a force against the first direction 111 to the first

Pantograph 106 is deflected into a depression of the pickup holder 115. Thus, a movement of the first

Current collector 106 is released relative to the housing insert 105 via the pickup holder 115.

The first receptacle 152 and the second receptacle 153 have, for example, latching hooks or other elements in order to be able to hold the first current collector 106 and the second current collector 107. Figure 13 shows the housing 104 with inserted

Housing insert 105. The holding element 110 is in the

Recess 150 disposed and holds the housing insert 105 along the first direction relative to the housing 104 fixed.

In addition, a cover guide 154 is shown. The cover guide 154 guides the movement of the housing cover 119 relative to the housing along the second direction 112. FIG. 14 shows the housing insert 105 in the housing 104 with the first current collector 106 and second inserted

Current collector 107. The housing insert 105 is fastened to the housing 104 in such a way that the first current collector 106 and the second current collector 107 are reliably fastened to the housing 104. The first pantograph 106 and the second

 Current collector 107 are offset along the third direction 113 to each other. In particular, the first current collector 106 projects beyond the housing 104 counter to the third direction 113. Thus, a point of attack for a

Moving realized. The second current collector 107 is set back.

FIG. 15 shows the further housing insert 118 according to one exemplary embodiment. The further housing insert 118 has a third receptacle 155 for the third current collector 108. The further housing insert 118 has a fourth

Receiving 156 for the fourth pantograph 109. The third receptacle 155 and the fourth receptacle 156 each have latching hooks or the like to the third

Each of the current collector 108 and the fourth current collector 109 can be reliably held on the further housing insert 118. Figure 16 shows the further housing insert 118 with mounted third pantograph 108 and fourth pantograph 109. On the pantographs 108 and 109 are taker guides 157 formed to guide the movement of the pantograph relative to the housing 104 along the first direction 111.

FIG. 17 shows a further housing insert 118 mounted in the housing 104. The further housing insert 118 securely holds the third pantograph 108 and the fourth pantograph 109 in the housing 104. The third pantograph 108 and the fourth

Current collector 109 project in particular in the third direction 113 via the housing 104. Thus, one is

Implementation point for a move realized. Figure 18 shows a current collector, the first

 Pantograph 106, the second pantograph 107, the third pantograph 108 or the fourth pantograph 109 or another pantograph can be. In particular, the

Pantograph 106 to 109 of identical construction. The

Current collector 106 to 109 has a coupling body 126, which is formed in particular from a plastic. The coupling body 126 can be coupled to the housing insert 105 and / or the further housing insert 118. The current collector 106 to 109 has the current-carrying element 127, which is formed in particular from an electrically conductive material. The current-carrying element 127 has a

Contact tip 120 on. The contact tip is used for

Contacting the line 138 and forming a

electrical connection between the pantograph 106 to 109 and the line 138th

The current collector 106 to 109 has a cable opening 129. The cable opening 129 serves to receive an electrical conductive cable or an electrically conductive line. One end of the electrically conductive cable is

for example, plugged into the cable opening 129. The

opposite end, for example, the

Functional insert 101 electrically coupled.

The coupling body 126 has the pickup guide 157. In addition, the coupling body 126 has a clearance 121. The franking serves as counter element to the receptacles 152, 153, 155, 156.

The current collector 106 to 109 has an actuating element 114. The actuating element serves for the deflection of the retaining element 110 from its rest position when the

Current collector 106 to 109 in the housing insert 105 at the stop

116 is arranged. For example, the actuator 114 is part of a bottom of the pantograph of FIG. 106.

FIG. 19 shows a part of the current tap arrangement 100 in a sectional view. The first current collector 106 and the second current collector 107 are held in their respective receptacles 152 and 153 along the second direction 112 and the third direction 113. As can be seen from FIG. 19, it is possible for the first current collector 106 and the second current collector 107 to be offset relative to one another along the third direction 113. This allows in the assembled ready state, an increase in the distance between the two current-carrying elements 127. The first pantograph 106 and the second pantograph 107 are offset along the second direction 112 to each other. The first

Pantograph 106 and the second pantograph 107 are in particular arranged offset to one another, as the Lines in the bus bar in two planes along the second direction 112 are arranged offset from one another.

Figures 20 and 21 each show a sectional view of the Stromabgriffsanordnung 100 in the assembled ready state. Between the coupling body 126 and the

Power guide element 127 is a spring 128 is arranged. The spring exerts a spring force in the second direction 112. The functional insert 101 is mechanically coupled to the support rail 102 and, in particular, immovable against the second direction 112. Thus, the Stromabgriffsanordnung 100 is stably stored in the mounting rail 102. Thus, the spring 128 presses the current-carrying element 127 in the second direction 112 against the line 138. The housing cover 119 is deflected counter to the second direction 112 from its rest position, thus releasing the contact tip 120.

Between the cable opening 129 and the current-carrying element 127, an electrical connection 130 is provided. The electrical connection 130 is formed for example of an electrically conductive material such as a metal and in particular at least partially resilient. A line is along the third direction 113 in the

Cable opening 129 can be inserted and jammed

for example, with the electrical connection 130th

mechanically. Through the contact between the line and the electrical connection 130, an electrical connection is formed. Between the electrical connection 130 and the

 Current-carrying element 127 is a sliding contact 131

educated. So is the electric current or the

electrical voltage from the current-carrying element 127 on the electrical connection 130 transferable and vice versa. The sliding contact 131 allows the movement of the

Power guide element 127 relative to the other current collector 106 and in particular to the electrical connection 130 and the cable opening 129th

The busbar system 103 has the busbar 133 and the functional insert 101 with the Stromabgriffsanordnung 100. The functional insert 101 is in particular a luminaire or a luminaire arrangement which can be used in the busbar system 103. The busbar 133 has the support rail 102, on which the functional insert 101

can be attached. The busbar 133, which may also have a plurality of busbar elements, has over the entire length of the busbar

133 running electrical supplies and

Data supplies on. At various points it is possible, by means of the Stromabgriffsanordnung 100 power to supply various electrical components

tap off. In addition, it is possible to use the

Current tap arrangement 100 also lines 138 too

contact those who do not serve the power supply,

For example, data transmission lines or

Control lines. Due to the arrangement of the cable holder

134 in the mounting rail 102 so that the lines 138 along the third direction 113 and along the first direction 111 are arranged side by side, it is possible to dispense with an extra channel, for example in the mounting rail or in the functional insert 101, in conventionally the lines are arranged. The lines 138 of the busbar system 103 can be used over their entire length without extra insulation in the

Conduit holder 134 may be arranged. Thus, there is no localized stripping at the positions at which the functional insert 101 is to be contacted. Due to the particular arrangement of the current collectors 106 to 109 in the housing 104 and the housing cover 119 creepage currents or other interactions between the current-carrying elements 127 are sufficient without additional insulation

prevented. The individual lines 138 are sufficient due to their positioning in the line holder 137

protected from each other, for example, by the staggered arrangement along the second direction of adjacent lines 138 to each other.

In addition, in the busbar system 103, a plurality of lines, for example for the normal power supply, the emergency power supply and control lines or

Lines for data transmission, realizable, while the outer dimensions of the system flexibly specified. A deviation from desired dimensions of the mounting rail 103, for example, along the first direction 111 is

preventable. The busbar system 133 is designed in particular, the emergency light standard DIN 6059822 with a

Lamp insert to meet, which is also suitable for normal operation. Here, due to the displaceability of the current collector 106 to 109 relative to the housing 104 same Stromabgriffsanordnung 100 and thus the same

Functional insert 101 usable as for the normal

Supply of light.

The lines 138 are arranged in the line holder 134 so that in compliance with air gaps and creepage distances the Displacement of the pantograph 106 to 109 is possible. It is the phase selection in the normal network between the phases LI, L2, L3 possible with N. In addition, a selection of the emergency power grid L ', N' and L '', N '' possible. In addition, a shift between Dali 1 and Dali 2 is possible, for example, between two different data networks, control networks or other networks that are not or not primarily the supply of electrical energy. The lines 138 for the phases LI, L2, L3, L 'and L "are in particular in one

common level. The lines for the Dali election, ie for Dali 1 and Dali 2, lie in particular in a further common level. The two planes are spaced apart along the second direction 112. This will

For example, a small space allows compliance with all air creepage distances. The displacement of the current collector 106 to 109 is done in particular by hand without tools.

The current tap arrangement 100 has a plurality of

Pantographs 106 to 109 on. It can be provided four pantographs, it can also more or less

 Pantograph be provided. The current collectors 106 to 109 are in the base housing 104 and in particular in the

Housing insert 105 and the other housing insert 118 inserted. For receiving and guiding serve the receptacle 152, 153, 155 and 156 and the picking guide 157 and the

Clearance 121. The current collectors 106 to 109 each have a cable opening 129, also called a cable receptacle. Here can be wired. The current-carrying element 127 serves for making electrical contact with one of the lines 138.

On the spring-mounted housing cover 119 are the

Protective elements 139 to protect the current-carrying elements 127th and in particular the contact tips 120 are provided. The

Protective elements 139 additionally serve to maintain the specified clearances and creepage distances and for correct positioning. Proper positioning of the current tapping assembly 100 relative to the conductor holder 134 is further accomplished by the projection 144 and the ridge 147

guaranteed. This is also 180 ° Verdrehschutz

guaranteed. So can not be contacted the wrong way around. For the Dali displacement, the third pantograph 108 and the fourth pantograph 109 are with the other

Housing insert 118 connected. The two current collectors 108 and 109 are only displaceable together in the composite. So you can move from D1 + and Dl- to D2 + and D2-.

The first pantograph 106 and the second pantograph 107 are positioned in the housing insert 105. For the selection of the normal operating power network, the second current collector 107 is positioned so that it always contacts the neutral conductor N. The first current collector 106 is relatively displaceable between the phases LI, L2 and L3. For emergency network selection, the current tap assembly 100 is designed such that when the first pantograph 106 reaches the position associated with L3, further pushing of the first

Pantograph 106 in the first direction 111 of

 Housing insert 105 taken. Thus, the second

Current collector 107 automatically from its position N

moved simultaneously with the first pantograph 106. Thus, the first pantograph 106 and the second

Pantograph 107 from the position L3 and N on L 'and N' shifted. Another shift to L '' and N '' is possible. In the last area is just a move of the first pantograph 106 and the second pantograph 107 together in a composite possible.

When moving the first pantograph 106 of the

Position associated with L3, the holding member 110 is pressed after. This releases the possibility of moving the housing insert 105. Now you can move to L 'and N' and further to L '' and N ''. The second pantograph 107 is attached to the housing insert 105. When pushing back L 'and N' to L3 and N, the pickup holder 115 serves to hold the first one

Current collector 106 relative to the housing insert 105th Das

Retaining element 110, when displaced against the first direction 111, requires in particular a smaller one

 Force to overcome as a customer support 115. Thus, the position L3 and N can be reached. For another

Moving the first pantograph 106 from L3 to L2 overrides the pickup bracket 115. The position N of the second current collector 107 is held. The housing insert 105 is opposite to the first direction 111 at one

Side wall 122 (Figure 10) of the housing 104 at. On

Moving the housing insert 105 relative to the housing 104 against the first direction 111 is thus not possible.

By arranging the lines 138 in the line holder 134 in a plane, it is sufficient for line selection, the

Pantograph 106 to 109 to move along a single direction 111.

The current tap assembly 100 allows use of the functional insert 101 for all applications, in particular for a normal application, use as emergency lighting, a Dali election. There are no special variants with their own wiring necessary. In particular, the DIN EN

60598222 complied with the busbar system 102, without different functional inserts 101 are required.

This reduces costs and variants. In addition, a user has a free choice as to which functional inserts 101 should be used.

Figures 22 to 27 show the principle of selection of

different lines 138.

In FIG. 22, the first current collector 106 is arranged in a position in which it contacts the line 138a, ie LI. The second pantograph 107 is in one position

arranged by contacting the line 138d, ie N.

The third pantograph 108 and the fourth pantograph 109 are only displaceable together and so on

arranged that the lines 138b and 138c are contacted, so D1 + and D1-.

FIG. 23 shows the phase selection after the first one

Pantograph 106 has been moved by one position. The first current collector 106 has been moved to the position that contacts the line 138e, ie L2. This shifting of the first current collector 106 has not changed the position of the second current collector 107. Also, the third pantograph 108 and the fourth pantograph 109 were not moved thereby. FIG. 24 shows the phase selection in which the first one

Pantograph 106 has been moved to the position that belongs to L3. The first pantograph 106 now contacts the lead 138f. By moving the first pantograph 106, the position of the second current collector 107, the third current collector 108, and the fourth current collector 109 has not been changed respectively. Figure 25 shows the phase selection in which an emergency power network L 'and N' was selected. The first pantograph 106 has been shifted from position L3 to position L 'such that the first pantograph 106 contacts the line 138g. This shifting of the first current collector 106 also results in a displacement of the second current collector 107, so that it now contacts the line 138h. The two

Current collector 106 and 107 are now coupled together, so that they can only be moved together with each other.

FIG. 26 shows the selection of a further emergency power network L "and N". Moving the first pantograph 106 to the position associated with L '' causes the second pantograph 107 to also be displaced. Thus, the first current collector 106 now contacts the line 138i and the second current collector 107 contacts the line 138k.

Figure 27 shows the change of the selection on the second line level. In particular, this selection, which is realized by a displacement of the third pantograph 108 and the fourth pantograph 109, regardless of the

Phase selection. The third pantograph 108 and the fourth

Pantographs 109 are only common with each other

displaceable. Thus, shifting from, for example, D1 + to D2 + also translates from D1 to D2. The third current collector 108 and the fourth current collector 109 thus contact the lines 138m and 138n after being moved. The invention is not limited by the description based on the embodiments of these. Rather, the invention encompasses every new feature as well as every combination of features, which in particular includes any combination of features in the patent claims, even if this feature or combination itself is not explicitly described in the claims
