Abstract

A current conducting system, in particular for lighting systems of the most varied types, has a current conducting rod, at least 50 % of the cross-section area thereof being occupied by at least two mutually-isolated metallic current conductors. Thus it is possible to work with high current densities, especially when using the current conducting system in the low voltage range. The current conducting rod is preferably round, so that holding clamps that carry electric consumers such as lamps, fans, etc. can be rotated thereon. Advantageous implementations of the holders allow the holders to swing as well, so that the user is virtually free to arrange and position the electric consumer as he wishes.

Description

conductor arrangement

Description

The invention relates to a current conductor arrangement in the form of a current conductor rod which has at least two metallic current conductors which are insulated from one another.

Current conductor arrangements of this type have grooves or recesses, in each of which a metal strip with a small cross-sectional area is inserted. Contacts of the electrical consumers, which are attached to the conductor rod, are in electrical contact with the metal strips in the groove of the conductor rod for current transmission. An axial displacement of the load contacts on the current conductor rail is possible, but not a rotation of the electrical load on the outer circumference of the current conductor rod, since the electrical contact of the load is inserted into the groove or grooves containing the metal strip and thus the current conductor. In addition, due to the metal strip having a small cross section, only low current intensities can be used with the known current conductor arrangement.

The invention is therefore based on the object of creating a current conductor arrangement which, with the simplest handling and assembly, allows great flexibility in the attachment, alignment and adjustment of the electrical consumers, for example lighting fixtures, can be operated with high current intensities and yet in a simple and cost-effective manner can be manufactured and installed.

Based on the current conductor arrangement mentioned at the outset, the stated object is achieved in that at least 50% of the cross-sectional area of the current conductor rod consists of the material of the current conductor. In contrast to conventional current conductor arrangements, in which only a thin metal strip with a small cross section is used as the current conductor, in the current conductor arrangement according to the invention the cross section of the current conductor rod is at least

50% from the material of the current conductor, i. That is, the current conductor has a high cross section, so that the current conductor arrangement according to the invention can also be subjected to high currents, as is the case with low-voltage systems, for example. The material of the conductors thus also forms a significant part of the interior of the conductor bar.

According to a preferred embodiment of the invention, the current conductor rod consists of at least 80% of the material of the current conductors. In this way, the conductor rod is used even better for conducting high currents. Due to this high proportion of metal, the current conductor arrangement can therefore also be heavily loaded in the low-voltage range.

Although the current conductor rod can also have a square, rectangular or oval cross-section, the other is. Embodiment of the invention, form the conductor rod with a round cross section, particularly advantageous. This makes it possible to attach and adjust electrical consumers, which--as will be described in detail below--on the surface of the conductor rod, not only axially, but also as desired in terms of the angle of rotation. It is particularly advantageous that the insulating material and the material of the current conductors form a surface that is uniformly circular in cross section; i.e. That is, the current conductor surface is not radially offset from the insulating surface of the current conductor cable, but both

Materials form a uniform circumference. On this way, the twisting of an electrical load attached to the current conductor rod is readily possible, so that. the user is free to choose both in terms of the axial position and in terms of the rotational position when attaching the electrical consumers and the consumers can easily attach or change their position as desired.

In particular when the current conductor arrangement according to the invention is used in the low-voltage range, the metallic current conductors on the surface of the current conductor rod are freely accessible for making contact. As a result, simple retaining clips can be used for attachment, which are either conductive themselves or have internal contact surfaces for making contact with the current conductors of the current conductor rod.

According to a preferred embodiment of the invention, the freely accessible peripheral surfaces of the conductor and the peripheral patches of the insulating material alternate around the circumference of the conductor bar. The design of the cross-sectional shape of the current conductors within the current conductor bar can be selected depending on the given circumstances or the conditions that occur. It is particularly advantageous to manufacture the current conductor rod from segments or partial segments of the current conductor and insulating material that alternate over the circumference.

According to a further embodiment of the invention, the freely accessible circumferential areas of the current conductors each have a circumferential angle that is smaller than the circumferential angles of the insulating circumferential areas. In this way, by simply rotating a retaining clip on the conductor rod, it is possible to move the contact surfaces of the clip into and out of contact with the conductors of the conductor to bring stabs. This results in a simple way of switching on and off.

It is particularly advantageous if, in the case of a conductor bar with two metal conductors, their freely accessible peripheral surfaces have a peripheral angle of 80° and the insulating peripheral surfaces have a peripheral angle of 100° each. In this way it is ensured that a retaining clip which has a contact angle on the conductor rod of approximately 90° on both sides can be safely "switched" in the manner described above.

In connection with the exemplary embodiments described above, it should again be pointed out that even with a relatively large circumferential angle of the insulating material on the circumferential surface, the proportion of the conductor in relation to the cross section of the conductor rod can be large, since the interior of the conductor rod - apart from a relatively thin insulating layer or plate - consists of the metallic current conductor material can exist.

According to a preferred embodiment of the invention, the current conductor bar can also be in a curved form, with the metallic current conductors being arranged in the inner and outer radius of curvature. The metallic current conductors therefore form the tension and pressure band in a bent current conductor rod.

In a further preferred embodiment of the invention, the material of the current conductors is pressed with the insulating material. In this way, with simple Her Position an intimate connection of the current conductor metal with the Isolatiαnsmaterial.

Due to its simple structure, the current conductor rod according to the invention can be cut to length by the user himself, depending on his wishes. The current conductor rods can be coupled with one another by simple assembly on the cut side.

The surface of the conductor rod is preferably finely ground.

The current conductor arrangement according to the invention is suitable not only as a conductive element, ie as a current conductor, but also as a supporting element for a wide variety of uses. For example, the current conductor rod according to the invention can be used as a load-bearing and conductive element for current and lighting systems, for example in the form of stand rods, gallery rails, decorative elements, shelf and support elements, light rails, etc. In the technical field, the current conductor bar can also be used as a supporting sliding element for transfer lines, as a carrier rail for modern pneumatic tube systems, as a current conductor for galvanic systems or as a contact rail in the laboratory area, in particular for connecting low-voltage units. It is also possible to use the current conductor bar as a signal or alarm line for high-frequency signals modulated onto the carrier voltage, for example alarm signals. Due to the simple, stable and for the user having a large variety of construction, it is possible to provide the current conductor arrangement according to the invention practically unlimited for the most diverse applications. According to a particularly advantageous embodiment of the invention, electrical loads, such as lighting fixtures, fans, motors, clocks, winches, electrical components, etc., are attached to the conductor bar by means of retaining clamps, the retaining clamps having inner contact surfaces which are connected to the conductors of the conductor bar for the electrical supply of the consumers in be in contact. As already explained, with a round conductor bar it is possible not only to move the holding clamps axially on the conductor bar, but also to rotate them in a plane perpendicular to the axis of the conductor bar. The holding clamps can be locked in a simple manner, analogous to the clothes pegs, by snapping them vertically onto the conductor bar, whereby on the one hand a mechanically and electrically firm connection between the conductor bar and the holding clamp is ensured without loosening a screw and on the other hand an axial displacement or rotation of the clamp is possible .

A further embodiment of the invention consists in the provision of connecting devices which mechanically and electrically connect two conductor rods, each having two conductors, to one another. In this way it is possible to lengthen the current conductors as desired.

It is preferably provided that the connecting devices each consist of two electrically conductive elements which can each be screwed to a current conductor, the elements not being in contact with one another. Since the individual conductors are to remain electrically insulated even when a conductor bar is continued, the connecting devices are therefore designed in such a way that one element always connects only the corresponding two conductors of two conductor bars.

It is particularly advantageous if the electrically conductive elements are cylinder segments whose inner radius of curvature is essentially the same as the radius of the current conductor rod. In this way, cuff-like connection devices result, in which the current conductor rods have a firm hold and are reliably electrically connected to each other. The segment angles of the cylinder segments are preferably less than 180° in order to prevent the cylinder segment-shaped elements from touching after assembly.

According to a further embodiment of the invention it is provided that the electrically conductive elements are angle connector elements whose legs to be connected to the current conductors have the shape of a cylinder segment whose inner radius of curvature is essentially equal to the radius of the current conductor rod. The connector angles can preferably be 90°, but also any other angle. This results in a wide variety of mounting and assembly options for the current conductor arrangement according to the invention. In this case, the connecting devices can be fastened to the current conductors in a simple manner with screws, which have previously been provided with corresponding threaded bores. Installation is extremely simple, and a wide variety of shapes and constructions are possible with the current conductor arrangement according to the invention in any environment, even without manual skills and technical knowledge.

The invention is explained in more detail below with reference to the drawing, for example. 1 shows an embodiment of a round current conductor rod according to the invention, FIG. 2 shows a cross section through that shown in FIG

Current conductor bar on an enlarged scale, Fig. 3a an embodiment of a holding clamp according to the present invention in side view,

3b shows the retaining clip shown in FIG. 3a in a viewing direction changed by 90°, FIGS. 4a, 4b and 4c a retaining clip leg in each of 90° different viewing directions, FIGS. 5a, 5b and 5c a contact spring in each by 90° different viewing directions, Fig. 6a and 6b an embodiment of a holder for an electrical consumer and Fig. 7a, 7b and 7c connecting devices for connecting round conductor rods. The current conductor rod 1 shown in perspective in FIG. 1 has two current conductors 2, 3, which are electrically insulated from one another with an insulating material 4. Between the current conductors 2 and 3 there is an intermediate layer 5 of the insulating material.

As can be seen from FIGS. 1 and 2, the current conductor rod 1 has a round cross section in the exemplary embodiment shown. The outer surfaces 6, 7 of the current conductors 2 and 3 form part of the circumference of the entire current conductor rod 1. The remaining circumferential areas of the current conductor rod 1 are formed by the surface of the insulating material 4.

The entire conductor bar 1 is preferably finely ground and has a homogeneous, circular surface. The conductor surfaces 6, 7 are exposed and are used to make contact with retaining clamps to be described below, with which electrical consumers are clamped to the conductor arrangement.

The shape of the current conductors 2 and 3 inside the current conductor rod is such that the majority of the cross-sectional area of the current conductor rod 1 consists of the current conductor material. This results in a large conductor cross-section in relation to the cross section or diameter of the conductor bar 1, so that the conductor bar 1, despite its compactness, can conduct currents with high current intensities without the conductor bar 1 heating up.

Grooves 8 on the current conductors 2, 3 (cf. in particular FIG. 2) serve to connect the insulating material 4 to the current conductors 2, 3 in a mechanically fixed manner. As an alternative to the embodiment of the conductor rod 1 shown in FIGS. 1 and 2, there is also the possibility of constructing the conductors and the insulating material as segments of a circle. However, the embodiment shown in FIGS. 1 and 2 is superior to an embodiment with circular segments in that a larger cross-sectional area of the current conductor rod 1 can be used for the current conductor.

1 and 2 represent a current conductor arrangement with two current conductors. Of course, it is also possible to create current conductor rods with more than two current conductors in order to have several current phases and to be able to supply electrical consumers with electricity independently of one another, without having to for the Electrical consumers supplied with different current phases have their own current conductor arrangements or current conductor rods.

Depending on the particular application, it is also possible for the current conductor rod not to be round but to be oval, square or rectangular in cross section. However, the round shape has the advantage that retaining clamps can also be rotated around the current conductor rod and thus brought into any desired position.

Fig. 3a and 3b show an embodiment of a retaining clip. Between two holding clamp legs 9, a holder 11 is screwed on by means of a screw 10, which has, for example, a Larapen socket or other attachment option for an electrical consumer, for example a fan, a motor, a clock or other device. The holder 11 is rotatable about the axis of the screw 10 between the holding clamps. The holding clamp legs 9 are on the respective Inside designed so that they fit on the conductor rod 1. Contact springs 12 are provided for making contact, which are attached inside the retaining clamp legs 9, as will be explained in detail below.

Both the retaining clamp legs 9 and the contact springs 12 are made of an elastic material, so that the entire retaining clamp can be pressed onto the conductor rod 1.

For the sake of better understanding, FIGS. 4a, 4b and 4c show a holding clamp leg again as an individual part from the various sides. A hole 13 is provided for the screw connection. Around the hole 13 there is a recess 14 in which the contact spring 12 (cf. FIGS. 5a, 5b and 5c) lies. As can be seen in particular from FIG. 5b, the shape of the contact spring 12 in the area where it rests on the current conductor rod corresponds to the round shape of the holding clamp leg 9, as can also be seen from FIGS. 3a and 3b. The bulge 15 of the retaining clip leg is the complementary shape of the current conductor rod 1; In the illustrated embodiment, the conductor rod 1 is round, so that the bulge 15 is in the form of a segment of a circle. A nose 17 of the contact spring 12 is located in a groove 16 at the end of the retaining clamp leg 15 for fixing the contact spring also at the end of the retaining clamp leg 9.

The contact spring 12 conducts the current from the conductor rod 1 via metal discs, for example copper discs 18 to electrical connections of electrical consumers that are attached to or in the holders 11 .

A preferred embodiment of the holder shown in Figs. 3a and 3b, in particular its attachment arm 19, on which the retaining clip legs 9 are attached with the contact springs 12, is shown in Figs. 6a and 6b.

In a chamber 20 of the holder 11 is an electrical consumer, such as a lamp base attached. One of the two connecting cables is passed through the wall through two bores 21, so that the stripped, free end of one connecting cable is in the circular recess 22 on one side of the holding arm and the other free end of the other connecting cable is in the circular recess on the other side of the support arm 19 is located. A metal disc, preferably a highly conductive copper disc, is placed on each of these free conductor ends lying in the recesses and, when the retaining clamp is assembled, rests on that part of the contact spring 12 which is connected by the screw 13 between a retaining clamp leg on the one hand and the retaining arm 19 of the holder 11 is arranged. By tightly screwing the holding clamp legs by means of the screw 13, the disk 18 is pressed firmly onto the conductor ends of the electrical load lying in the circular recesses 22, so that a good contact and a low ohmic resistance is achieved. On the other hand, the metal disks 18 rest against the parts of the contact springs 12 pressed between the holding clamp legs 9, which are also made of a conductive material, preferably copper. In this way, despite a very good electrical connection between the connecting wires and the discs 18, there is a good sliding effect between the discs 18 and the contact springs 12, so that the holding arm 19 and thus the holder 11 can be pivoted with respect to the holding clamp legs without a Screw would have to be loosened or removed. In the simplest way possible, this results in a great variety in the attachment and adjustment of electrical Ver users, such as lighting fixtures, fans, etc., since the possible rotation of the retaining clamp on the conductor rod 1 and the pivoting of the holder 11 with respect to the retaining clamps for the user at any time in the simplest of catfish a readjustment or change is practically unlimited.

FIGS. 7a, 7b and 7c show exemplary embodiments of connecting devices with which round conductor rods 1 each having two conductors 2, 3 can be connected to one another both mechanically stable and with good electrical contact.

Fig. 7a is provided for the connection of two current conductor rods 1 in a straight direction. This connecting device according to FIG. 7a has two essentially symmetrical elements 71 and 72 which are designed as cylinder segments. The inner radius of the cylinder segments 71 and 72 essentially corresponds to the radius of the conductor rod.

The conductor rods 1 to be connected are provided with threaded bores in the two conductors 2 and 3 at the ends to be connected, which run in the radial direction. The threaded holes still end in the respective conductors 2 and 3 as blind holes.

The elements 71 and 72 in the form of a segment of a cylinder are then laid over the ends of two conductor rods 1 to be connected. Screws are passed through the prepared holes 73 and 74 in the upper element 71 and through corresponding holes in the lower element 72 (not shown in the figure). This results in a sleeve-like connection two conductor rods 1.

To ensure that the two conductor bars do not come into electrical contact with each other, the cylinder segments have a segment angle less than 180° so that after attachment to the conductor bars the segments do not touch but leave a gap. Due to the blind threaded holes, it is also not possible for an electrical connection to be made between the conductors via the screws.

Fig. 7b shows a connecting device for an angled connection. The angle is 90° in the illustrated embodiment. The angles of the two angle elements 75 and 75 on both legs again have the cylinder segment shape and the screw holes 77, 78, as have already been described with reference to the embodiment shown in FIG. 7a. The conductor rods 1 to be connected can be mitred. All that is required, however, is that the ends of the current conductor rods 1 to be connected as far as possible into the

Project angle connector elements that the screws can be screwed into the corresponding threaded holes in their conductors 2 and 3.

7c also shows a right-angled connecting device with connecting elements 79 and 80. The connection of the conductor rods 1 takes place in the same way as in the connecting devices shown in FIGS. 7a and 7b and described in connection therewith. However, the connecting device shown in FIG. 7c is required in addition to the connecting device shown in FIG. 7b if a connection of the current conductor rods is desired in a direction pointing out of the plane spanned by the legs of the connecting device shown in FIG. 7b is. In the angle connectors shown in Figures 7b and 7c, the connector angle is 90°. If desired, angle connection devices with connection angles other than 90°, e.g. B. be provided with a connection angle of 60 °.

The connecting devices enable flexible and varied assembly and construction of the conductor rods 1 to form the most diverse conductor arrangements.

The invention has been explained using preferred exemplary embodiments. However, modifications, configurations and extensions are possible for a person skilled in the art without departing from the idea of the invention.

Description

The invention relates to a current conductor arrangement in the form of a current conductor rod which has at least two metallic current conductors which are insulated from one another.

Current conductor arrangements of this type have grooves or recesses, in each of which a metal strip with a small cross-sectional area is inserted. Contacts of the electrical consumers, which are attached to the conductor rod, are in electrical contact with the metal strips in the groove of the conductor rod for current transmission. An axial displacement of the load contacts on the current conductor rail is possible, but not a rotation of the electrical load on the outer circumference of the current conductor rod, since the electrical contact of the load in the metal band, and thus the current conductor having groove or. Grooves is used. In addition, due to the metal strip having a small cross section, only low current intensities can be used with the known current conductor arrangement.

The invention is therefore based on the object of creating a current conductor arrangement which, with the simplest handling and assembly, allows great flexibility in the attachment, alignment and adjustment of the electrical consumers, for example lighting fixtures, can be operated with high current intensities and yet in a simple and cost-effective manner can be manufactured and installed.

Based on the current conductor arrangement mentioned at the outset, the stated object is achieved in that at least 50% of the cross-sectional area of the current conductor rod consists of the material of the current conductor. In contrast to conventional current conductor arrangements, in which only a thin metal strip with a small cross section is used as the current conductor, in the current conductor arrangement according to the invention the cross section of the current conductor rod consists of at least 50% of the material of the current conductor, i.e. the current conductor has a large cross section on, so that the current conductor arrangement according to the invention can also be subjected to high currents, as is the case, for example, with low-voltage systems. The material of the conductors thus also forms a significant part of the interior of the conductor bar.

Material of the conductors. In this way, the conductor rod is used even better for conducting high currents. Due to this high proportion of metal, the current conductor arrangement can therefore also be heavily loaded in the low-voltage range.

Although the current conductor bar can also have a square, rectangular or oval cross section, the further embodiment of the invention, constructing the current conductor bar with a round cross section, is particularly advantageous. This makes it possible to attach and adjust electrical consumers, which--as will be described in detail below--on the surface of the conductor rod, not only axially, but also as desired in terms of the angle of rotation. It is particularly advantageous that the insulating material and the material of the current conductors form a surface that is uniformly circular in cross section; ie the conductor surface is not offset radially with respect to the insulating surface of the conductor cable, but both materials form a uniform circumference. On In this way, the twisting of an electrical consumer attached to the current conductor rod is easily possible, so that the user can choose freely both with regard to the axial position and with regard to the rotational position when fastening the electrical consumers and can easily attach or remove the consumers in their position as desired. can change .

In particular when the current conductor arrangement according to the invention is used in the low-voltage range, the metal current conductors on the surface of the current conductor rod are freely accessible for making contact. As a result, simple retaining clips can be used for attachment, which are either conductive themselves or have internal contact surfaces for making contact with the current conductors of the current conductor rod.

This ensures that a retaining clip that has a contact angle on the conductor rod of approximately 90° on both sides can be safely "switched" in the manner described above.

In connection with the exemplary embodiments described above, it should be pointed out again that even with a relatively large circumferential angle of the insulating material on the circumferential surface, the proportion of the current conductor in relation to the cross-section of the current conductor bar can be large, since the interior of the current conductor bar - apart from a relatively thin insulating layer or plate - consists of the metallic current conductor material can exist.

The invention is explained in more detail below with reference to the drawing, for example. 1 shows an embodiment of a round current conductor rod according to the invention, FIG. 2 shows a cross section through that shown in FIG

The current conductor rod 1 shown in perspective in FIG. 1 has two current conductors 2, 3, which are electrically insulated from one another with an insulating material 4. Between the current conductors 2 and 3 there is an intermediate layer 5 of the insulating material.

As can be seen from FIGS. 1 and 2, the current conductor rod 1 has a round cross section in the exemplary embodiment shown. The outer surfaces 6, 7 of the current conductors 2 and 3 form part of the circumference of the entire current conductor rod 1. The remaining circumferential areas of the current conductor rod 1 are formed by the surface of the insulating material 4.

The entire conductor bar 1 is preferably finely ground and has a homogeneous, circular surface. The conductor surfaces 6, 7 are exposed and are used to make contact with retaining clamps to be described below, with which electrical consumers are clamped to the conductor arrangement.

As an alternative to the embodiment of the conductor rod 1 shown in FIGS. 1 and 2, there is also the possibility of constructing the conductors and the insulating material as segments of a circle. However, the embodiment shown in FIGS. 1 and 2 is superior to an embodiment with circular segments in that a larger cross-sectional area of the current conductor rod 1 can be used for the current conductor.

1 and 2 represent a current conductor arrangement with two current conductors. Of course, it is also possible to create current conductor rods with more than two current conductors in order to have several current phases and to be able to supply electrical consumers with electricity independently of one another, without having to for the Electrical loads supplied with different current phases require their own current conductor arrangements or current conductor rods.

Between two holding clamp legs 9, a holder 11 is screwed on by means of a screw 10, which has, for example, a lamp socket or other mounting option for an electrical load, for example a fan, a motor, a clock or other device. The holder 11 is rotatable about the axis of the screw 10 between the holding clamps. The holding clamp legs 9 are on the respective Inside designed so that they fit on the conductor rod 1. Contact springs 12 are provided for making contact, which are attached inside the retaining clamp legs 9, as will be explained in detail below:

Both the retaining clamp legs 9 and the contact springs 12 are made of an elastic material, so that the entire retaining clamp can be pressed onto the conductor rod 1.

For the sake of better understanding, FIGS. 4a, 4b and 4c show a holding clamp leg again as an individual part from the various sides. A hole 13 is provided for the screw connection. Around the hole 13 is a recess 14 in which the contact spring 12 (see Figures 5a, 5b and 5c) lies. As can be seen in particular from FIG. 5b, the shape of the contact spring 12 corresponds to that in the region of the contact on the current conductor rod. the round shape of the holding clamp leg 9, as can also be seen from FIGS. 3a and 3b. The bulge 15 of the retaining clip leg is the complementary shape of the current conductor rod 1; In the illustrated embodiment, the conductor rod 1 is round, so that the bulge 15 is in the form of a segment of a circle. A nose 17 of the contact spring 12 is located in a groove 16 at the end of the retaining clamp leg 15 for fixing the contact spring also at the end of the retaining clamp leg 9.

The contact spring 12 conducts the current from the conductor rod 1 via metal discs, for example copper discs 18 to electrical connections of electrical consumers that are attached to or in the holders 11 .

A preferred embodiment of the holder shown in Figs. 3a and 3b, in particular its attachment arm 19, on which the retaining clip legs 9 are attached with the contact springs 12, is shown in Figs. 6a and 6b.

In a chamber 20 of the holder 11 is an electrical consumer, such as a lamp base attached. One of the two connecting cables is passed through the wall through two bores 21, so that the stripped, free end of one connecting cable is in the circular recess 22 on one side of the holding arm and the other free end of the other connecting cable is in the circular recess on the other side of the support arm 19 is located. A metal disc, preferably a copper disc with good conductivity, is placed on each of these free conductor ends lying in the recesses and, when the retaining clamp is assembled, rests on that part of the contact spring 12 which is connected by the screw 13 between a retaining clamp leg on the one hand and the retaining arm 19 of the Holder 11 is arranged. By tightly screwing the holding clamp leg by means of the screw 13, the disc 18 is pressed firmly onto the conductor ends of the electrical load lying in the circular recesses .22, so that a good contact and a low ohmic resistance is achieved. On the other hand, the metal disks 18 rest against the parts of the contact springs 12 pressed between the holding clamp legs 9, which are also made of a conductive material, preferably copper. In this way, despite a very good electrical connection between the connecting wires and the discs 18, there is a good sliding effect between the discs 18 and the contact springs 12, so that the holding arm 19 and thus the holder 11 can be pivoted with respect to the holding clamp legs without a Screw would have to be loosened or removed. In the simplest way possible, this results in a great variety in the attachment and adjustment of electrical Ver users, such as lighting fixtures, fans, etc., since the possible rotation of the retaining clamp on the conductor rod 1 and the pivoting of the holder 11 with respect to the retaining clamps for the user at any time in the simplest way a new setting or change is practically unlimited.

FIGS. 7a, 7b and 7c show exemplary embodiments of connecting devices with which round conductor rods 1 each having two conductors 2, 3 can be connected to one another both mechanically stable and with good electrical contact.

Fig. 7a is provided for the connection of two current conductor rods 1 in a straight direction. This connecting device according to FIG. 7a has two essentially symmetrical elements 71 and 72 which are designed as cylinder segments. The inner radius of the cylinder segments 71 and 72 essentially corresponds to the radius of the conductor rod.

The conductor rods 1 to be connected are provided with threaded bores in the two conductors 2 and 3 at the ends to be connected, which run in the radial direction. The threaded holes end in the respective conductors 2 and 3 as blind holes.

The elements 71 and 72 in the form of a segment of a cylinder are then laid over the ends of two conductor rods 1 to be connected. Screws are passed through the prepared holes 73 and 74 in the upper element 71 and through corresponding holes in the lower element 72 (not shown in the figure). This results in a sleeve-like connection two conductor rods 1.

In order to ensure that the two conductor bars do not come into electrical contact with one another, the cylinder segments have a segment angle which is less than 180° so that after attachment to the conductor bars the segments do not touch but a gap is left. Due to the blind threaded holes, it is also not possible for an electrical connection to be made between the conductors via the screws.

Fig. 7b shows a connecting device for an angled connection. The angle is 90° in the illustrated embodiment. The angles of the two angle elements 75 and 75 on both legs again have the cylinder segment shape and the screw holes 77, 78, as have already been described with reference to the embodiment shown in FIG. 7a. The conductor rods 1 to be connected can be mitred. All that is required, however, is that the ends of the current conductor rods 1 to be connected as far as possible into the

Project angle connector elements that the screws can be screwed into the corresponding threaded holes in their conductors 2 and 3.

7c also shows a right-angled connecting device with connecting elements 79 and 80. The connection of the conductor rods 1 takes place in the same way as in the connecting devices shown in FIGS. 7a and 7 and described in connection therewith. However, the connecting device shown in FIG. 7c is required in addition to the connecting device shown in FIG. 7b if a connection of the current conductor rods is desired in a direction pointing out of the plane spanned by the legs of the connecting device shown in FIG. 7b is. In the angle connectors shown in Figures 7b and 7c, the connector angle is 90°. If desired, angle connection devices with connection angles other than 90°, e.g. B. be provided with a connection angle of 60 °.

The connecting devices enable flexible and varied assembly and construction of the conductor rods 1 to form the most diverse conductor arrangements.

The invention has been explained using preferred exemplary embodiments. However, modifications, configurations and extensions are possible for a person skilled in the art without departing from the idea of the invention.
