DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(12) FIG. 1 and FIG. 2 illustrate a device 1 according to the invention for the contacting of electrical conductors which are not illustrated, and an electrical plug connector, illustrated as plug 10. This device 1 is embodied here as a terminal and connecting clamp.

(13) The device 1 comprises a front housing part 2 and a rear housing part 3. In the front housing part 2, electrical connections can be made, and, in the rear housing part 3, further electrical connections can be made. In the front housing part 2, the contacting points 7 can be embodied as per se known connection terminals. In the rear housing part 3, the contacting points 9 can be embodied as per se known female plug connections for the contacts 11 of the plug 10. Furthermore, the plug 10 can comprise connection terminals 12 in order to allow an electrical connection with further electrical elements which are not illustrated.

(14) The lower side 5 of the rear housing part 3 of the device 1 is arranged offset relative to the lower side 4 of the front housing part 2 of the device 1, so that a step exists between lower side 4 of the front housing part 2 and lower side 5 of the rear housing part 3. The upper side of the front housing part 2 and the upper side of the rear housing part 3 are preferably provided on the same plane, as illustrated. The shoulder between the lower side 4 of the front housing part 2 and the lower side 5 of the rear housing part 3 allows the arrangement of contacting points 8 on the lower side of the device 1, which are illustrated by way of example in this embodiment as terminal connections.

(15) Furthermore, fastening elements 16 can be provided on the lower side of the device 1, here, as snap-fastening element, in order to a fastening of the device 1 with elements which are not illustrated. In particular, the device 1 can be fitted to lighting modules or lighting elements.

(16) The device 1 also comprises a per se known earth 13 on the lower side 4 of the front housing part 2. According to the invention, an earth strip 14 is provided on the lower side 4 of the front housing park 2, which is disposed in constant contact with the earth 13 and comprises spring arms 15 at the side of the front housing part 2. In particular, in the case of the contacting points 7, a terminal connection is provided for the earth.

(17) It is also conceivable that the earth 13 is dispensed with and that only the earth strip 14 is present on the device 1. In this case, an electrical connection or respectively contact connection is present between a terminal connection of the contacting point 7 and the earth strip 14.

(18) FIG. 3 illustrates one possible area of application for the device 1. The device 1 is arranged in a rail system 17, preferably a rail system for lighting elements, which are not illustrated, wherein the device 1 can be fitted in a sheet aperture 18 of the rail system 17.

(19) The earth strip 14 is clamped in the sheet aperture 18 by means of its spring arms 15, and an earth contact to the rail system is therefore provided.

(20) FIG. 4 and FIG. 5 illustrate a further embodiment of the device according to the invention, wherein an additional connection possibility is provided, here, by comparison with FIG. 1, in the rear housing part 3. The contacting point 22 is provided on the upper side of the device 1. In this embodiment, a plug 19 matches the contacting point 22, wherein the plug 19 is largely similar to the plug 10. During assembly, the contacts 20 of the plug 19 are plugged into the contacting points 22. The terminal connections 21 of the plug 19 are provided for electrical conductors, not illustrated, which are per se known or respectively conventional for such applications, for further electrical connection.

(21) FIG. 6 shows a cross-sectional view of the device, wherein it is evident that the punched part 23, which ensures the electrical contact connection of the contacting point 7 within the device 1, also ensures the electrical contact connection of the contacting point 8 within the device 1. No additional punched parts or electrical connecting element is necessary for the contacting point 8.

(22) FIG. 7 and FIG. 8 show a third embodiment of the device according to the invention. In the front housing part 3, the additional connection possibility to the contacting point 9 is embodied as contacting point 27. In this embodiment, a plug 24 for the contacting point 27 matches the electrical connection, wherein the plug 24 is provided, for example, for a mains supply. The contacts 25 of the plug 24 are plugged into the contacting points 27 during assembly. The connecting point 26 of the plug 24 are preferably provided for a further plug, not illustrated, which is per se known or respectively conventional for such applications, for further electrical connection.

(23) An exploded view of this embodiment is shown in FIG. 9 and FIG. 10. In the contacting points 27, punched parts 29 are provided, in the contacts 25 of the plug 24, punched parts 28 are similarly provided. It is advantageous if the punched parts 28 and 29 are each integrated in their components. Per se known punched parts can be used, even the same but contrary punched parts, on the one side, as fork contact and on the other side as transverse contact, so that they match one another. Such a combination between plug and coupling particularly suitable for relatively high current passages (16A) and relatively large cross-sections.

(24) Connecting elements 30 and 31, which are conductive, connect the punched parts 23 to the respective contacting points 27 and 9. In the case of the connecting elements 30, a hook is present at one end, which is plugged into the punched parts.

(25) Visible details in the drawings which have not been expressly described here are also the subject matter of the invention. Further embodiments of the device according to the invention which are not illustrated here should not be excluded from the invention.
