(14) Below, an embodiment example of the present invention is explained by referring to the attached FIGS. 1 through 11.

(15) FIG. 1 shows a strongly schematic depiction of a vehicle 70 and a charging station 60. The vehicle 70 comprises a battery pack 50 that is provided in an exchangeable manner on the vehicle 70. If applicable, several battery packs 50 may also be provided on the vehicle.

(16) Here, the battery pack 50 is an electrical component 1 that comprises a housing 2 and plug contacts 3 on a contact mount 7.

(17) In addition to the utilization of the electrical component 1 in accordance with the invention, on a vehicle, the utilization on a stationary device or other mobile devices or installations is also possible.

(18) Here, in the embodiment example, the battery pack 50 as electrical component 1 may have a high weight of 100, 150 or even 200 kg. For purposes of exchanging the battery pack 50, a forklift (not depicted here) may be used that removes the battery pack 50 from the vehicle 70 and takes it to the charging station 60 that may e.g. be realized in a shelf-like manner and that comprises different charging positions for battery packs 50.

(19) The forklift or a conveyor belt or transport belt or similar device transports the battery pack 50 to an unoccupied charging position and connects the battery pack 50 with the plug contacts 3 through 6 to the charging station 60.

(20) Thereby, the electrical component 1 is reliably connected with the charging station 60. This is ensured by the dual floating arrangement of the plug contacts 3 through 6 via the contact mount 7 on the housing 2 of the electrical component 1.

(21) FIG. 2 shows the area of the connection of the electrical component 1, whereby the plug contacts 3 and 5 in the case of direct current serve as plus or minus poles, respectively, while the plug contact 4 preferably serves as PE contact. It is also possible to provide additional plug contacts. In the present embodiment example, an additional plug contact 6 is provided that here also may comprise several poles and that is realized as a connector plug 28.

(22) Opposite the housing 2, the contact mount 7 that is here realized in plate form is held in a floating manner via, according to the embodiment example, a total of four compensating devices 8. The compensating devices 8 are connected firmly and rigidly through screws 14

(23) with the housing 2. The discs 13 of the compensating devices 8 prevent the contact mount 7 from being detached unintentionally from the housing 2.

(24) On the electrical component 1, bushes 39 in the form of guide bushes are provided with which at least a rough leading of the electrical component takes place when connecting the electrical component 1 to an electrical component 1 a.

(25) An electrical component 1a is depicted in FIG. 3, and it comprises guide pins 18, two of which are provided here in this embodiment example. It is also possible to provide an electrical component 1 or 1a with only one guide pin 18 or, however, with three or four guide pins 18.

(26) The electrical component 1a also has plug contacts 3 through 6 that may be connected in a plug-like manner with the corresponding plug contacts at the electrical component 1. If applicable, the electrical component 1a also may comprise a contact mount 7 which then, in turn, is held in a floating manner opposite the housing 2 of the electrical component 1a.

(27) The guide pins 18 are throughout most of their length realized as tubes and have here three annular thickenings 20 in each of which an outer diameter 27 is significantly greater than the other outer diameter 26. At the tip of the guide pin 18, a tip 23 is provided that may be rounded, conical or similarly shaped, and with which an initial and simple centering of the electrical component 1 takes place when the electrical component 1 with the bushes 39 is slid onto the tips 23 of the guide pins 18. The annular thickenings 20, having only a small tolerance between the outer diameter 27 and the annular thickening 20 and the inner diameter of the bush 39, allow for a very precise and reproducible contacting of the electrical component 1.

(28) Due to the fact that the outer diameter 27 is only present at the annular thickenings 20, the electrical component 1 is reliably prevented from tilting during contact. Therefore, the mounting forces remain insignificant.

(29) FIG. 4 shows a top view onto the contact area of the electrical component 1 with the housing 2 in the base position 16. In the base position 16, the contact mount is in a resting position relative to the housing 2. This means that the compensating devices 8 are not deflected.

(30) Each of the plug contacts 3, 4, 5 and 6, respectively, is arranged in a floating manner vis-a-vis the contact mount 7. In at least one direction and here in both the lateral and vertical direction, a certain adjustability of the individual plug contact 3 through 6 vis-a-vis the contact mount 7 is present. The aforesaid adjustability may e.g. be in the range of between 0.1 and 0.5 mm. Thereby, an exact adjustment of each individual plug contact 3 through 6 is made possible, even after the orientation of the contact mount 7 through the guide pin 18, thereby preventing especially high mounting forces from arising during contact. In this case, an adjustment by a distance 42, which may measure up to e.g. 0.5 mm, took place, both vertically and laterally. In other specific embodiments, smaller and/or also greater adjustment movements are possible. The contact mount, 7, however, may be preferably deflected by a few millimeters.

(31) FIG. 5 depicts the deflected position 17 in which the contact mount 7 was deflected vis--vis the resting position 16. In this case, an adjustment by a distance 38, which may measure up to e.g. 5 mm, took place, both vertically and laterally. In other specific embodiments, smaller and/or also greater adjustment movements are possible.

(32) FIG. 6 shows a strongly schematic lateral view of a guide pin 18 with annular outer contours 20 and 25.

(33) In this case, such an outer contour 20 and/or 25 may arise through an annular thickening, but also through individual nubs 24 that are distributed around the circumference that here are depicted schematically in cross-sectional form. It is of the essence that in the locations of the annularly enlarged outer contours 20 and 25, an enlarged outer diameter 27 is present that e.g. is by 0.1 to 0.5 mm larger than the outer diameter 26 of the actual outer surface of the guide pin 18. The guide pin 18 extends along a longitudinal stretch 19, whereby in certain and pre-defined distances the annularly enlarged outer contours 20 and/or 25 are provided.

(34) Especially, the first or an annularly enlarged outer contour 20 and/or 25 is provided in a manner such that a simple contacting of the plug contacts 3-6 is allowed. At the very moment when the plug contacts are establishing contact, the annularly enlarged outer contour 20 and/or 25 ensures a tighter fit at the bush 39.

(35) FIG. 7 depicts the cross-section A-A from FIG. 5. In this case, the deflected position 17 is depicted in which the contact mount 7 was moved laterally by a distance 38 in which, as now may be seen in FIG. 7, the contact mount 7 was deflected by an angle 37 vis--vis the housing 2. When connecting the electrical component 1 to e.g. a charging station 60, this enables an angle deviation by an angle 27 that may measure e.g. 1 degree or 5 degrees or a similar magnitude. This enables a clearly more flexible contacting of an electrical component 1, resulting especially with large-scale and heavy electrical components, such as battery packs 50, in a considerable simplification of the contact process.

(36) As can be seen from FIG. 7, each compensating device 8 has one centering cone 9 that is arranged on one side 11 of the contact mount 7. On the other side 12, a disc 13 is provided that covers the opening 10 in the contact mount 7 and thus holds the contact mount firmly to the housing 2, although an angle and lateral orientation is possible. Preload devices 15 that are realized as coil springs serve to preload the compensating device into the base position 16.

(37) FIG. 8 depicts a connector plug 28 that was here sketched as plug contact 6 into the prior Figures. The connector plug 28 has a base body 31 and a contact body 32 in order to receive a plurality of plug contacts. Furthermore, a pull relief device 30 is provided that here comprises a pull relief 33 and holding catches on the base body 31.

(38) The pull relief 33 is realized as a strip-shaped flat metal sheet 34, thus enabling a simple stamping production process with low waste.

(39) Close to one end of the pull relief 33, openings 36 at the pull relief 33 are provided that act together with the holding catches 35 of the base body 31 in order to produce an interlocking connection between the pull relief 33 and the base body 31 and/or the contact housing 29, respectively.

(40) The connector plug 28 is depicted in FIG. 9 in a lateral view, and in FIG. 10 in a top view. The connector plug 28 may in addition to power output connections that are here sketched in largeralso have a number of data connector plugs so that it may be possible to provide an electronic device or a small computer or a load device or similar with the necessary energy, while at the same time enabling the exchange of data that were generated or processed.

(41) While the holding catches 35 are provided in a mounted condition at the openings 36 in and/or at the base body 31, the other end of the pull relief 33 protrudes from the base body 31. At the other end, grooves 40 may be provided in order to there provide the connection of a cable binder or other components. For purposes of assembly, the pull relief with the openings 36 is first inserted into the base body 31 of the connector plug 28. Subsequently, the openings 36 are put over the holding catches 35 inside the base body 31, and the pull relief 33 is placed against an inner wall of the base body 31. Subsequently, the contact body 32 with the contact cases that are not depicted here, may be introduced into the concave base body 31, so that the contact body 32 and the pull relief 33 are received in an interlocking manner at the base body 31. By mounting the connector plus 28 on a circuit board or on the contact mount 7, the contact body 32, too, is safely received on the base body 31.

(42) In sum, the invention enables the use of an electrical component 1 in the form of e.g. battery packs or accumulator packs 50 or other electrical components in which a reliable and safe contact action with low transitional resistances takes place, wherein the tolerances to be adhered to when generating the plug connection are relatively minor since the contact mount 7 and the individual plug contacts 3 through 6, respectively, are held in a floating manner. Thereby, the mounting forces, when establishing the connection, and also the separation forces during the separation of the connector plugs are reduced significantly, while at the same time providing a contact surface with high conductivity.

(43) While the tolerances of the plug contacts that are contacting one another are e.g. around 1/10 or 1/100 mm, respectively, considerably higher tolerances may be chosen for establishing the connection, so that e.g. a lateral shift of 5 mm or similar may be compensated.

(44) Each individual plug contact 3 through 6 may e.g. be arranged on a bore with over-dimension, thus moving in all lateral directions by a certain degree.

(45) The connector plug in accordance with the invention has a simple structure and is easily assembled and disassembled, thereby ensuring reliable function with little assembly effort.
