Description

The present invention relates to a power supply device according to the preamble of claim 1.

A lighting device is off DE 20 2004 006 641 U1 previously known. It serves the in DE 20 2004 006 641 U1 disclosed rail lamp assembly at the same time as a shelf rail on the shelves can be fastened.

Rail systems are also known in which rails are fastened, for example, to the ceiling of a room. The rails have on their front side extending over the entire length of the rail engagement opening for adapters, which have electrical contacts for contacting the arranged in the rail busbars. The electrical contacts can be brought by twisting with the busbars of the rail in contact. However, rails are also known in which by the insertion of the adapter in the rail, the electrical connection between the contacts of the adapter and the busbars is made.

A disadvantage of the prior art rails and lighting devices is that elongated lamps, in particular tubular lamps, such. LED fluorescent tubes, or heavy electrical loads, which would exert adverse lateral forces on the adapter and rail, are not usable, since they are not designed for this purpose. In addition, each mounted on the rail light is always attached only by means of a single adapter, so that only relatively light fixtures are fastened to the rail, or the rails and adapters robust and stiff enough must be designed to accommodate the holding forces and bending moments occurring.

The object of the present invention is to provide a power supply device and corresponding adapters, wherein electrical consumers of very different size and weight, in particular also elongate lighting means, such as e.g. Light tubes, are fastened to an elongated body.

This object is advantageously achieved by a power supply device having the features of claim 1. Advantageous embodiments of the power supply device according to claim 1 result from the features of the dependent on the claim 1 dependent claims 2 to 15; the adapters required for the power supply device are described and claimed by the claims.

The invention is based on the concept of the invention that at least one electrical consumer can be connected and fastened to the base body by means of two adapters which can be attached to the base body at freely selectable locations on a base body. By attaching the electrical load on both sides, the adapter must absorb lower forces and torques. Thus, even heavy consumers, such as fans, can be attached to the main body and electrically connected, with only one adapter for electrical power to the consumer must serve. Of course, it is also possible that both adapters have an electrical function. Advantageously, the power supply device according to the invention can also serve and be designed only as a pure lighting device, can be attached to the bulbs or lamps at different locations on the fixed to a wall or a ceiling base body. As a result, it is advantageously possible to arrange tubular light sources, in particular LED tubes, in the required length and at the required position in the room. Of course, other, as described in this application, electrical consumers can also be attached and electrically powered by means of appropriate adapter to the lighting device. Thus, it is also possible that in addition to the held by two adapters electrical consumers and consumers are attached only by means of a single adapter to the body and electrically powered.

The electrical consumer can optionally also be attached directly to the base body by additional fastening means.

If the electrical load is a tubular lamp, e.g. an LED tube, so the tube is used with their two-sided sockets in corresponding sockets of the two holding adapter. If the adapters have the same dimensions, then the tube runs parallel to the main body. It is of course also possible that the illuminant or another electrical consumer is not parallel, but at an angle to the base body can be arranged by differently shaped adapter.

In the simplest case, the base body is designed as a commercially available power distribution rail, which has a groove extending in the longitudinal direction of the rail groove, which the through-opening or. Engaging opening for the adapter forms and are arranged in the busbars, which can be brought into electrical connection with the contacts of the adapter.

However, it is also possible for the main body to have a plurality of through-openings, in particular at equidistant intervals from one another in which the adapters are anchored. The passage openings also produce the electrical connections to the conductors or data lines arranged in the main body. For this purpose, pass through, in particular slidably disposed in the adapter housing, contacts the access openings. The distances or the grid dimension in which the pass-through openings are arranged relative to one another can be selected so that a system of differently long tubular lamps can be arranged in any combination on one or more base bodies arranged one behind the other. Thus, fluorescent tubes or LED tubes exist in different lengths.

The through openings can all have the same dimensions, diameters and / or cross-sectional shapes. In order to produce reverse polarity protection, the access openings can also be designed and arranged such that the adapters can be fastened to the base body only in one orientation, thus ensuring that only the mutually corresponding contacts of the adapters and conductors of the base body can be connected to one another ,

If an electrical consumer only needs to be supplied with electrical energy from one side, then only one of the two adapters holding the consumer has to be equipped with electrical contacts.

The adapters can advantageously have at least one socket into which the base of an electrical consumer can be inserted. The socket can optionally be arranged displaceably on the adapter housing, so that tolerances can be compensated. Additional spring elements can be provided for a bias, so that the electrical contacts are always pressed together safely.

Advantageously, the adapters are designed such that only after the attachment of the consumer to the adapter, the consumer comes into electrical connection with the conductors. For this purpose, an adapter may have a corresponding actuating element, whereby the adapter to the switch becomes. The actuating element can be secured by an additional locking device.

The Figures 1 and 2 show a power supply device according to the invention, which has a base body 2, which has a longitudinal side 2a with a longitudinal groove 2b, in which the adapter 1, 11 are used. In the longitudinal groove 2b are extending in the longitudinal direction extending, not shown, arranged conductor. The adapters 1, 11 have electrical contacts 1c, which are adjustable by an adjusting mechanism 1j after insertion of the adapter 1, 11 in the direction of the conductors, so that an electrical contact between the contacts 1c and the conductors is constructed. By means of the locking wheel 1d, the adapter can be fastened to the base body 2 via the projections 1b engaging in undercuts of the groove 2b become. The main body can be a commercially available busbar, for example from ERCO®. The pedestals 1a of the adapters 1, 11, as in FIG FIG. 3 shown, may be formed according to the adapter used for the bus bar used and known. At least two adapters 1, 11 are to be fastened to the main body, which carry and electrically supply an electrical load 3 between them. In the Figures 1 and 2 the electrical load is a tubular light source, which may be, for example, an LED light tube. The adapters 1, 11 have a housing 1e which is formed or arranged in each case on the base 1a and which carries or forms at least one mount 1f, 1f '. The sockets can be formed with and without electrical contacts. If an electrical consumer only needs to be electrically supplied from one side, or is allowed to, it makes sense if only one socket 1f has electrical contacts. This can be prevented inter alia, that in a wrong installation, in which the consumer is used upside down in the adapter, short circuits or other damage caused by false electrical potentials. Also, it makes sense if the adapters 1, 11 and the base body 2 are formed such that the adapters 1, 11 can be used only in one direction, so that it can not come to an electrical reverse polarity. If necessary, corresponding right and left adapters 1, 11 are provided.

Like in the FIG. 1 shown, two consumers 3 are attached by means of two adapters 1 on the base body 2 respectively. The adapters 1 each have only one socket 1f, 1f 'which supply the sockets 1f via electrical contacts to the consumer 3. The sockets 1f 'may be formed as "blind sockets" which have no electrical contacts. Of course, it is also possible that all adapters have only sockets with electrical contacts. If, in addition, the electrical consumers are still controlled via data lines, special adapters can also be provided which only transmit data, the electrical supply being made via adapters which transmit only electrical current. Nevertheless, it is also possible that an adapter transmits both electrical energy and data.

As in FIG. 2 shown, an adapter 11 may also have two facing away from each other versions. As a result, two adjoining consumers 3 can be kept space-saving by an intermediate adapter.

It is optionally possible for an adapter 1 to take on additional functions. Thus, in the housing 1e, a region 1g may be formed, in which a lighting means is arranged, which serves as an emergency light, for example. This can for example be switched on permanently or in an emergency, eg via a separate power supply, operated ( FIG. 4 ). The area 1g can be covered by means of an attachable cap 1g '. The cap 1g 'may be formed in different colors, so that in this way the color of the emergency light 4 can be determined. Alternatively, as in the FIGS. 5 and 6 represented, instead of an emergency light 4, a speaker 5 or a motion detector 6 in the area 1g of the adapter 1 are arranged. The electrical components arranged in the region 1g can be connected via separate contacts of the adapter to separate current and / or data conductors of the main body 2, so that they can be operated independently of the electrical load 3.

The FIG. 7 shows a second alternative embodiment of a power supply device, in which are attached as electric consumers tubular lighting means 3 by means of the adapter 21 on the base body 12. The base body 12 has on its one longitudinal side, in particular rectangular, square, circular and / or elliptical, through-openings 12b, in which the adapters 21 are fastened and through which the electrical contacts of the adapters 21 reach into the base body 12 in order to generate an electric current Make contact with the arranged in the base body 12 conductors (not shown) produce. At the end of the main body 12, an end cap 12k may optionally be arranged. The main body can be attached with its lower longitudinal side 12u on a wall or a ceiling, such as a building or a piece of furniture.

Like in the FIG. 8 1, the through-openings can be arranged in two rows R1, R2, with the through-openings 22a, 22b of each row R1, R2 being arranged at equidistant, ie constant, distances from one another, so that the adapters are placed at arbitrary positions on the base body 12, 22, 22 'are fastened. Of course, it is possible that more than two rows R _i can be provided by access openings.

Alternatively, through openings 22a, 22b of the rows R1 and R2 may have different cross-sectional openings. If the contacts of the adapters and / or the fastening means of the adapters, with which the adapters are anchored or fastened in the through openings, have corresponding cross-sectional shapes, such as the associated through openings, this ensures that the adapters are only in alignment with the main body at this can be attached. Thus, the cross-sectional openings of the through-openings 22a are rectangular, in particular square, and the cross-sectional openings of the through openings 22b are round, in particular circular or elliptical. Accordingly, the contacts and / or fastening means of the adapter are to be formed.

In the FIGS. 9 to 12 Various possible electrical consumers 13, V, R and La are shown, which can be fastened between two adapters 21 on the main body 12. In this case, the consumer 13 is a lamp, the consumer V is a fan, the consumer R is a smoke detector and the consumer La a in the direction of arrow relative to the adapters 21 pivotable light source S.

The Figures 13, 13a and 13b show a further possible embodiment of the power supply device according to the invention. The main body 32 has, on its longitudinal side receiving the adapters 31, side by side and into one another sockets 32f, which are arranged at equidistant distances from one another. The sockets 32f are circular in shape and merge into each other, since the distance of the juxtaposed sockets 32f is smaller than the radius of the circular sockets 32f. The circular sockets are formed by the circular walls 32c. In the bottom wall 32w, the through-openings 32a and 32b are arranged, through which the correspondingly formed contacts 31k of the adapter 31 are insertable. The passage openings 32a, 32b are arc-shaped and have at their one end 32a ', 32b' on a larger diameter, so that the contacts 31k are inserted with their enlarged diameter end. By turning the adapter 31, this is held in a form-fitting manner in the base body. The version of the body is thus of the type GU10 and forms a twist lock, formed by not only the electrical contact but also the adapter is mechanically attached to the body. The adapter housing 31g has a round portion 31a which corresponds to the walls 32c of the main body. In addition, the adapter housing has two sockets 31f which point away from one another, so that, for example, two light sources 3 can be attached to an adapter as electrical consumers and fastened in series one behind the other on the base body and can be electrically connected.

The FIGS. 14 to 14d show a further third possible embodiment of the power supply device according to the invention. In this embodiment, busbars L1 and L2 are arranged in the base body 42, which engage in recesses 42a 'of an insulating body 42a. The main body 42 may be made of any, in particular bending resistant material. However, it is optionally possible that bending-resistant profiles, in particular within the base body 42, are arranged, which ensure its stability. At its front longitudinal side, the base body has the passage openings 42b through which the fastening means 41r engage in the form of resilient latching noses and engage behind with their noses. The noses of the locking lugs 41r are slightly beveled, so that the adapter 41 is detachable from the base body 42 by a small amount of force. The electrical contacts 41k1 and 41k2 of the adapter 41 are displaceably mounted in the housing 41g of the adapter 41 by means of the actuating element 41b.

When inserting the latching lugs 41r of the adapter into the passage openings 42b of the base body 42, the contacts 41k1 and 41k2 are displaced upward, so that the latching lugs 41r can easily be pivoted from the edges of the passage openings. After the complete introduction of the detents, as shown in the partially sectioned illustration according to Figure 14a The electric contact between the contacts 41k1 and 41k2 with the resiliently formed regions L1c and L2c of the conductors L1 and L2 is produced by the actuation of the actuating element 41b, whereby the Contacts 41k1 and 41k2 are adjusted in the direction of the conductors L1, L2 ( FIG. 14b ). As soon as the contacts 41k1 and 41k2 reach through the through openings 42b, they prevent the latching lugs 41r from being able to be pivoted, as a result of which the adapter 41 is securely fastened to the base body 42. The electrical contacts 41k1 and 41k2 are fixed with their upper ends to the body 41p, which is connected to the actuating element 41b or integrally formed. On the body 41p contacts 41m are arranged, which correspond to contacts 41l of the socket 41f. The contacts 41l are arranged on a slider and locking element 41v and are displaced therefrom by the pressed-in actuating element 41b in the direction of the contacts 41m and finally pressed against them to form an electrical connection. This ensures that only after locking with the slide element 41v of the electrical load 3 is connected to the conductors L1, L2.

The adapter 41 may optionally also be designed such that the electrical load can only be removed from the holder 41f, 41f 'if at least the locking element in the form of the slider 41v is displaced into the unlocking position, and thus the consumer only removes it without current can be.

The FIGS. 14c show the main body and the adapter 41 in a sectional view. The left diagram shows the adapter with not yet actuated actuator 41b. The right illustration shows the locked adapter 41.

The FIGS. 15a to c show the main body 52 and the associated adapter 51 of a fourth possible embodiment. The adapter 51 has as in the FIGS. 14 to 14d shown adapter 41 via locking lugs 51r, which reach into the through-openings 52b and then engage behind. The detents are also prevented by the electrical contacts 52k1 and 52k2 on pivoting ( FIG. 15c ), whereby the adapter 51 is securely fastened to the main body 52. The electric contacts 52k1 and 52k2 are moved by the operating member 52b through the through holes 52b and brought into contact with the conductors L1 and L2, and are also in contact with the contact springs 51fk of the sockets 51f. The locking member 51s serves to lock the actuating means 51b in the lower position. It can additionally be provided that the electrical consumer can only be inserted or removed from the socket when the actuating means 51b is in its upper position, in which the contacts 51k1 and 51k2 are not connected to the conductors L1 and L2 ,

The FIGS. 16a to d show a main body 62 and the associated adapter 61 according to a fifth possible embodiment, in which the electrical contacts 61k1 and 61k2 of the adapter 61 with the resilient conductor portions L1c and L2c of the conductors L1 and L2 of the main body 62 in the contacted state, as shown in FIG FIG. 16a is shown to form a frictional connection, on the one hand ensures the electrical contact on the other hand, but also ensures the mechanical connection between the adapter 61 and the body. Locking lugs, as they were needed in the embodiments three and four, are not required here, but can of course be additionally provided. The frictional connections are formed by the contact areas L1c and L2c bent downwards by the electrical contacts 61ki. The conductors L1c and L2c thus prevent the removal of the contacts 61k1 and 61k2, whereby the adapter can not be lifted off the base body. Only when the unlocking 61o with its coaxial end 61o 'is pressed against the conductor portions L1c and L2c, they are moved away from the electrical contacts 61k1 and 61k2, whereby the adhesion is released. The electrical contacts 61k1 and 61k2 can then be displaced upward out of the region of the conductors L1 and L2, after which the adapter 61 can be removed as a whole from the main body 62.

The FIGS. 17a and b show the base body 62 of the embodiment described above in a slightly modified form, are provided in the flaps 62k as shock protection, which prevent direct access from the outside through the access openings on the conductors L1 and L2.

Of course, it is also possible that the passage openings of the embodiments described above by other contact protection measures, e.g. in the form of sliding elements, as they are known in child-safe sockets, are secured. It is also possible to provide rubber lips that close the passage openings until they are pivoted by the electrical contacts and / or locking lugs of the adapter. The openings closing or covering means also have the advantage that no dirt or small animals or insects can get into the interior of the body. If the passages are small enough from their cross-sectional openings, can be dispensed with an additional contact protection.

The FIG. 18 shows an adapter which is secured by means of an additional cap 53. The cap 53 has a hinge joint 53a through which its two halves can be placed around the upper housing area of the adapter and optionally also around an end face area of the consumer 3. The cap can be arranged for purely aesthetic reasons. However, it can also have a technical function. Thus, it can serve to actuate and / or secure the actuating element 51b. In the closed, so closed state thus the cap 53 actuates a switching element, whereby only then electrical contact between adapter and power distribution device is formed and the contact is disconnected when opening the door again.

Also, it can provide an extra grip for the consumer 3.

It is, of course, possible for a plurality of the above-described basic bodies to be arranged one behind the other and / or next to one another adjacent to or at a distance from each other, so that e.g. a continuously longer and / or wider basic body can be formed.

As described above, a prescribed adapter can be attached only by means of the electrical contacts on the base body. However, it is also possible to attach the adapter by other fastening means on the base body. Similarly, it is also possible that the electrical contacts of the adapter and additional purely mechanical fastening means are used for fastening the adapter to the base body. The additional fastening means can of course also engage in the passage openings of the base body and engage behind the boundary walls of the passage openings for a secure fit. Thus, locking lugs by pins, which have no electrical function, on pivoting, analogous to the embodiment according to. of the FIGS. 14 to 14d be prevented, the pins are adjusted, for example, with the electrical contacts of the adapter via the actuating element 41b or via a further actuator independently of the electrical contacts. So it is also possible to provide not only two electrical contacts, but more than two electrical contacts. It is also possible for the electrical contacts to contact the corresponding conductors of the basic body in succession, ie, with a time delay, so that, for example, it can be ensured that first the protective conductor and only then the phases and neutral conductors are contacted. When the contacts are disconnected, the phase (s) are removed first and then the protective conductor contact is removed at the end. This can be realized, for example, by staggered conductors or contacts.
