Definitions

  • the present invention relates to a lamp or an electrical unit which is provided for connection to a mounting rail, the mounting rail having a mounting rail profile with two side walls and at least one busbar with contactable lines arranged in the mounting rail profile.
  • Support rails with a support rail profile and a busbar held in the support rail profile are known from the prior art and are used, for example, to implement elongated so-called light band systems.
  • a known trunking system is sold by the applicant under the name “TECTON” and is characterized by the fact that lights or other electrical loads can be flexibly positioned on the trunking over the entire length of the system.
  • WO 2001/091250 A1 such a trunking system.
  • two conductor rails are arranged opposite one another on the two side walls of a U-shaped support rail profile that is open at the bottom.
  • the lines of the busbars are then contacted in that the lamp or the consumer has a rotatable contacting element which is inserted into the support rail from the underside and then rotated by approximately 45 °.
  • Contacts arranged on the contacting element are designed in such a way that they are swiveled out to the side as a result of the rotation and ultimately contact the lines of the busbars in the rotated state.
  • the rotatable contacting elements described above were designed and mounted on the lamp or the electrical consumer in such a way that they could be actuated, ie rotated, by a user from the underside of the lamp.
  • the luminaire or a carrier element of the luminaire or of the consumer was then attached to the mounting rail from the underside, the contacting element or elements then being rotated in this state in contact with the mounting rail.
  • the contacting elements had to be accessible for actuation from the underside of the luminaire or the consumer, which usually did not pose a problem, since elongated fluorescent lamps were used as the lighting means, which were only used after the luminaire had been attached to the mounting rail could easily be used by the consumer in the sockets of the lamp.
  • LEDs or LED circuit boards are predominantly used as lighting means in lighting technology, even in the case of lights that are intended for use in such mounting rails. Since the subsequent arrangement of LED light sources on a luminaire does not make sense or is possible and, moreover, a uniform light output can only be achieved if the LEDs are arranged more or less continuously evenly distributed over the entire length of the light strip system, it is As a rule, it is no longer possible to configure the rotatable contacting elements explained above in such a way that they are accessible from the underside.
  • a solution described, for example, in DE 10 2010 003 805 A1 therefore provides that the rotatable contacting element is designed with a lever which protrudes laterally outward through a slot in the support element of the lamp.
  • FIG. 4 Such a solution known from the prior art is shown in FIG. 4, the elongate carrier element 110 of a so-called bar light 100 being initially recognizable here, on which a contacting element 120 is rotatably mounted.
  • the carrier element 110 present in the form of a profile element must be attached from the underside to the support rail (not shown) of the trunking system and then the contacting element 120 must be rotated.
  • the carrier element 110 has side walls 111 on both longitudinal sides, an elongated slot 112 being formed on one side wall 111 through which the end region of a lever 125 connected to the contacting element 120 protrudes.
  • the lever 125 can be pivoted along the slot 112 between the two positions shown, with a corresponding rotation of the contacting element 120 then also taking place.
  • Contacts 122 of the contacting element 120 which are arranged on the outer circumference of the base body 121, are then pivoted out laterally in this case, so that they rest against the lines of the busbars come.
  • mechanical locking elements are also swiveled out in this case, which engage behind the corresponding projections of the mounting rail profile, so that in addition to the electrical contacting, a mechanical fastening of the light 100 on the mounting rail is also achieved.
  • the laterally protruding lever 125 shown in FIG. 4 thus enables the contacting element 120 to be rotated, the underside of the carrier element 110 of the lamp 100 being freely accessible despite everything and thus being able to be equipped with illuminants over the entire length, for example.
  • This solution accordingly already represents a step forward compared to the original variant, in which the locking element had to be actuated from the underside.
  • the lever 125 must protrude laterally to a certain extent in order to enable comfortable actuation of the contacting element 120.
  • the lateral slot 112 represents a permanent opening and thus a problem if the luminaire 100 is to be protected from the ingress of dust and / or moisture in order to meet the requirements of what is known as an IP protection class.
  • the present invention is therefore based on the object of offering an alternative possibility of reliably contacting the lines of a busbar positioned in a mounting rail profile, the above-mentioned disadvantages being avoided.
  • connection contacts are now not arranged on a rotatable body, but part of a linear, laterally adjustable contact block, which is located between an open position in which the contact element can be inserted and removed from the mounting rail profile, and a contact position in which the contact block with the Connection contacts is extended laterally to contact the lines, is adjustable.
  • a lamp or an electrical unit for a mounting rail which has a mounting rail profile with two side walls and at least one busbar which is arranged on one of the two inner sides of the side walls of the mounting rail profile and has electrically contactable lines
  • the Luminaire or the electrical unit has a contacting element for electrical and possibly mechanical connection to the mounting rail, and wherein the contacting element can be inserted into the mounting rail profile and has connection contacts which are adjustable so that the contacting element is in contact with lines when the contacting element is inserted into the mounting rail profile to get to the power rail.
  • Contacting element has at least one linear, laterally adjustable contact block with at least one connection contact, which is positioned between an open position, in which the contacting element can be inserted and removed from the mounting rail profile, and a contacting position, in which the contact block with the connection contact is extended laterally for contacting the lines , is adjustable.
  • a contacting element for electrically and mechanically connecting a lamp or an electrical unit to a mounting rail, which has a mounting rail profile with two side walls and at least one busbar which is arranged on one of the two inner sides of the side walls of the mounting rail profile and has electrically contactable lines , wherein the contacting element can be inserted into the mounting rail profile and has connection contacts which are adjustably mounted in order to enable the in a state inserted into the mounting rail profile
  • the contacting element has at least one linearly laterally adjustable contact block with at least one connection contact, which is adjustable between an open position, in which the contacting element can be inserted and removed from the support profile, and a contacting position, in which the contact block with the connection contact is extended laterally for contacting the lines.
  • the contacting element has two contact blocks with connection contacts pointing in opposite directions, both contact blocks being coupled in such a way that, starting from the open position, they can be moved away from one another into the contacting position Busbars corresponding to the side walls of the support rail are arranged, as is the case, for example, with the above-mentioned “TECTON” system. Both contact blocks can then move in opposite directions or towards one another in order to transfer the contacting element from a state in which it can be inserted into the support rail or removed from the support rail into one
  • Both contact blocks can advantageously interact with one another in order to use the linear movement according to the invention for contacting the lines.
  • both contact blocks are connected to one another via articulated arms that form a parallel guide.
  • the two contact blocks are mounted preloaded in the contacting position, with suitable pushing or actuating elements being arranged on the contacting element or a carrier element of the lamp or the electrical unit, which enable the contact blocks to be manually compressed into the open position . Only for the introduction or removal of the contacting element from the mounting rail therefore both contact blocks have to be temporarily pressed together. If, on the other hand, the pressure or actuation elements are relieved, the contact blocks automatically migrate to the side in order to contact the lines of the busbars.
  • Another preferred embodiment of the invention provides that the contacting element is designed such that an axially into the
  • Mounting rail profile directional movement is converted into a lateral movement of the two contact blocks.
  • the two contact blocks are connected to one another via articulated arms that form a toggle joint.
  • the toggle joint can be designed in such a way that when pressure is exerted on the contact blocks in a direction opposite to the direction of insertion into the mounting rail profile, the contact blocks are transferred from the open position to the contacting position.
  • the contact blocks When the contacting element is inserted into the support rail, the contact blocks automatically migrate laterally into the contacting position, which is a particularly efficient and convenient embodiment of the contacting element according to the invention.
  • a solution comparable to the variant just described provides that the two contact blocks are mounted on a carrier of the lamp or the electrical unit by means of a wedge guide in such a way that when pressure is exerted on the contact blocks in a direction opposite to the direction of insertion into the mounting rail profile Contact blocks are urged by a wedge arranged on the carrier from the open position into the contacting position. In this case, too, the insertion movement is automatically used to move the contact blocks laterally into the contacting position.
  • the contact blocks are preloaded into the open position, in particular are connected to one another accordingly via a tension spring.
  • the contact blocks of the contacting element according to the invention can also have outwardly facing latching elements for mechanical attachment to the mounting rail profile.
  • the effect can also be achieved in this case that, in addition to contacting the lines of the busbars, the luminaire or the electrical unit is also mechanically fastened to the mounting rail profile at the same time.
  • At least one of the contacts of the contacting element according to the invention can be supported on its contact block in a height-adjustable manner. This opens up the possibility of flexibly contacting the various lines of the busbars, for example in order to specifically assign a specific function to the consumer or the lamp.
  • the lamp according to the invention is preferably an LED bar lamp.
  • the configuration of the contacting element according to the invention opens up the possibility of continuously arranging LEDs as lighting means over the entire length of the lamp.

  • a special feature of this system is that the lines running along the mounting rail for powering the lights or consumers are stored in such a way that they can be contacted over the entire length of the trunking system, so that lights or other consumers are flexible can be arranged over the entire length of the trunking system.
  • the present invention is not limited to this special trunking system, but the contacting elements according to the invention can in principle always be used when corresponding contacts of the contacting element have to be moved laterally in order to contact the lines of a support rail of a trunking system in order to connect the lines of a Contact busbar.
  • the mounting rail with the busbars arranged therein is therefore only shown schematically.
  • contacting the lines of a busbar does not necessarily have to be used to supply the unit to be connected with power.
  • the connection to data lines used for communication would also be conceivable, whereby in particular the connection of sensors, cameras or similar components would also be conceivable, which transmit data on their own via the lines of the trunking system, which are then used, for example, for automated control of the system.

However, it is essential that the lines 25 are mounted in such a way that they are accessible from the interior 18 of the support rail 10 and can be contacted accordingly from this direction. However, the lines 25 do not necessarily have to cover the entire length Be accessible along the length of the system 1, but it would also be conceivable that contacting is only possible or provided in sections.
  • a so-called bar luminaire 30 is shown in the present figures, which, as shown in FIGS. 1a and 1b, rests on the underside of the mounting rail profile 15 in the assembled state and has an elongated profile body 31 as a supporting element.
  • the profile body 31 is used here in particular to support the lighting means, any components for powering the lighting means, and any optical components that may be present, which influence the light output of the lamp 30 in the desired manner.
  • the design of these components is, however, independent of the present invention, which is why these components are not shown in detail in the figures and should not be explained in more detail below.
  • the lamp 30 is designed to be mechanically attached to the support rail 10 and to contact at least some of the lines 25 of the two busbars 20, which is made possible with the aid of the contacting elements according to the invention described in more detail below.
  • the contacting elements are designed in such a way that they can be transferred from a first configuration to a second configuration.
  • the contacting element is designed in such a way that it can be introduced into the interior space 18 of the support rail 10 and in particular does not collide with the lower edges of the side walls 16 of the support rail profile 15. In this state, there is also no contacting of the lines 25 of the busbars 20. In the second configuration, however, the contacting element is in a state in which at least some of the lines 25 of the busbars 20 are contacted. Ideally, mechanical latching or locking elements also engage behind corresponding projections on the support rail 10, so that in addition to the electrical contacting, mechanical attachment to the support rail 10 also takes place. The contacting element is therefore also responsible for fastening the unit to be connected to the support rail 10. In the solution known from the prior art shown in FIG.
  • the contacting element was transferred from the first configuration to the second configuration by rotating it.
  • linear displacements or movements are now used in order to fulfill the above-mentioned functions.
  • Three preferred exemplary embodiments of this idea are to be explained in more detail below.
  • the first exemplary embodiment of a contacting element according to the invention is provided with the reference number 40.
  • it has two so-called contact blocks 41 and 42, which are arranged on both sides of a longitudinal center plane E and have contacts 43 pointing in opposite directions or respectively outward.
  • the number and the height positioning of the contacts 43 is shown in the figures only by way of example and can of course also vary.
  • one or some of the contacts 43 are height-adjustable on the corresponding blocks 41, 42, so that by appropriate positioning of the contacts 43 it can be determined which of the superposed lines 25 of the busbars 20 are to be contacted. If, for example, the different lines 25 are used for different phases of a power supply circuit or are used to provide a specific supply voltage or specific control information, a specific function can be assigned to the lights or, in general, to the connected unit.
  • the contacts 43 for example designed as contact tongues, can contact the lines 25, it must be possible to extend these contacts 43 to the side.
  • this is made possible by the fact that the contact blocks 41, 42 are coupled to one another via a so-called toggle joint 45.
  • This toggle joint 45 is formed by a vertically upwardly projecting first arm 46 which is rigidly connected to the carrier 31 of the lamp 30. At its upper end, the arm 46 is connected via a hinge 47 to two pivotably mounted arms 48, the end regions of which are in turn articulated to one of the contact blocks 41 or 42. Furthermore, a tension spring 49 is provided which connects the end regions of the two arms 48 to one another.
  • the toggle joint 45 formed in this way now enables the two contact blocks 41 and 42 to be transferred from the position shown in FIG. 1a, which corresponds to an open position of the contacting element 40, into the position shown in FIG. 1b.
  • both contact blocks 41 and 42 are laterally extended laterally, in such a way that the outer ends of the contact tongues 43 now come into contact with the lines 25 of the busbars 20.
  • latching lugs 44 of the contact blocks 41, 42 engage behind latching projections provided at the lower end of the side walls 16 of the support rail 10.
  • the lamp 30 is therefore not only electrically connected to the lines 25 of the busbars 20, but is also mechanically fixed to the support rail 10.
  • the position of the arms 48 in the contacting position of the contact blocks 41 and 42 shown is also such that the contact blocks 41 and 43 are locked in the position shown by the tension spring 49.
  • the contact blocks 41, 42 initially in the position illustrated in FIG. 1 a will come into contact with the horizontal wall 17 of the support rail 10 or with a stop 19 provided on the wall 17. If the carrier element 31 of the lamp 30 is now pushed further upwards, the pressure exerted by the wall 17 or the stop on the contact blocks 41, 42 counter to the insertion movement causes the toggle joint 45 this axial movement to deflect the contact blocks laterally 41 and 42 by pivoting the arms 48 about the hinge point 47 until they assume the position shown in FIG. 1b. As already mentioned, a dead center of the joint 45 is exceeded and the tension spring 49, which pulls the contact blocks 41 and 42 into the open position in the position in FIG.
  • FIGS. 1 a and 1 b therefore represents a very convenient way of enabling the lamp 30 to be connected to the support rail 10. It is only necessary to insert the luminaire 30 from the underside into the support rail 10 and to press it upwards with an appropriate force in order to achieve the configuration shown in FIG. 1b. This locking or contacting configuration can then be released again corresponding pulling on the lamp 30 can be achieved. If necessary, the webs 35 shown schematically in the figures can also be used here, which form a guide for the lateral movement of the two contact blocks 41, 42.
  • FIGS. 2a and 2b show a second exemplary embodiment of a contacting element according to the invention, now provided with the reference number 50.
  • This also offers the advantage that the two contact blocks 51, 52 provided in turn, which are equipped with corresponding contacts 53, come into contact with a stop 19 or the wall 17 when they are pushed into the receiving space 18 of the mounting rail 10 and then automatically migrate to the side. Again, the axial insertion movement is converted into a lateral movement of the contact blocks 51, 52.
  • a guide element 55 used for this purpose, with an approximately truncated cone-like cross-section, is in turn firmly connected to the support 31 of the lamp 30 and forms two guide surfaces 56 projecting upward at an angle which contact blocks 51, 52, which are in turn connected to one another via a tension spring 59, can slide.
  • the contact blocks 51, 52 here have side walls facing the guide surfaces 56, which have a corresponding inclination, so that a change in the height of the contact blocks 51, 52 compared to the guide element 55 is converted into a lateral movement.
  • the contact blocks 51 and 52 will initially come into contact with their upper sides against the wall 17 or the stop 19 when they are inserted into the interior of the support rail 10. A further pushing of the lamp 30 and thus of the contacting element 50 upwards then leads to the contact blocks 51,
  • the contact blocks 51, 52 then again assume a position in which, on the one hand, the contacts 53 contact the lines 25 of the busbars and, on the other hand, latching projections 54 engage behind the support rail 10.
  • the contact blocks 51, 52 then again assume a position in which, on the one hand, the contacts 53 contact the lines 25 of the busbars and, on the other hand, latching projections 54 engage behind the support rail 10.

  • FIGS. 3a, 3b show different variants of a corresponding parallel guide 65, the guide 65 in FIG. 3a being reached by a web 67 of the other contact block 61 that engages in a slot-like recess 66 of a contact block 62, whereas in the variant according to FIG 3b the parallel guide 65 is formed with the aid of two articulated arms 68.
  • both contact blocks 61, 62 are biased in an outwardly directed position.
  • leaf springs 69 FIGS. 3a and 3b
  • a spiral spring 70 positioned in the lower area (FIG. 3b). Both variants have the effect that the contact blocks 61, 62 are pretensioned in the outwardly directed contacting position.
  • both contact blocks 61, 62 are temporarily moved towards one another against the spring force, which can be done manually by means of two laterally provided pressure fields 71, 72. If these pressure fields 71, 72 are relieved in the inserted state of the contacting element 70 in the interior 18 of the support rail 10, the contact blocks 61, 62 automatically migrate to the outside again due to the spring force and, in turn, the lines 25 of the busbars 20 and additionally also a contact mechanical locking with the support rail 10 via the latching elements 64.

Abstract

L'invention concerne un luminaire (30) ou une unité électrique destinée à être raccordée à un rail de support (10) qui comporte un élément de mise en contact (40, 50, 60), qui peut être introduit dans le profilé de rail de support (15) et présente des contacts de connexion (42, 52, 62) montés de manière réglable pour s'appuyer contre des lignes (25) de la barre omnibus (20) dans un état dans lequel l'élément de mise en contact (40, 50, 60) a été inséré dans le profilé de rail de support (15). L'élément de mise en contact (40, 50, 60) a au moins un bloc de contact (41, 42, 51, 52, 61, 62) avec des contacts de connexion (43, 53, 63), qui est réglable linéairement latéralement entre une position ouverte et une position de contact.
