DETAILED DESCRIPTION OF AN EMBODIMENT OF THE INVENTION

[0063] In the following description of preferred embodiments of the invention, identical reference numerals refer to identical or similar components. For clarity, in the case of multiple identical parts in the figure generally only one of these parts is provided with a reference numeral.

[0064] The adaptive connector 1 shown in FIG. 1 comprises three lamella carriers to each of which a busbar 2 is attached by means of a screw 3. Both the lamella carriers and the bus bars 2 are of a conductive material, preferably copper or a copper alloy. The lamella carrier comprises a first 4 and a second part 5, between which a one-sided lamella basket 6 is clamped.

[0065] The lamella basket 6 is formed of a slotted and bent metal sheet and is resiliently elastic. Each of the lamellae of the lamella basket has a first end, where the lamellae are fixed relatively to each other, and a second, free end. The lamellae extend in mainly the direction of the symmetry axis of the lamella basket 6 and inwardly. The lamellae extend generally along the inner sidewalls of the sleeve-shaped second part 5 of the lamella carrier with the free ends pointing towards a mating opening 7 end of the lamella carrier.

[0066] Moreover, three adapter elements 8 are provided that have contact jacks in the form of contact pins 9, 10 on both ends. The contact pins 9 on one end of each adapter element 8, through the respective mating openings 7 of the lamella carriers, extends into the inside of the lamella baskets 6. The lamellae are elastically biased against the contact pins 9 to provide for a reliable electrical contact. The elasticity of the lamellae and the space between the lamellae and the wall of the second part of the lamella carriers 5 allows the contact pin 9 to be pivoted and translationally moved relatively to the lamella carrier while maintaining contact.

[0067] The three lamella carriers 8 are fixed in a shared housing 11 and the first parts 4 of the lamella carriers are accessible from the outside of the housing 11 so that the busbars 2 can easily be screwed to the lamella carriers. The adapter elements extend in cylindrical cavities in the housing 11 from the end of the housing 11 where the lamella carriers are located to the opposite end of the housing 11. The contact pins 10 on the ends of the adapter elements 8 opposite those that contact the adaptive connector's 1 lamella carriers are exposed to the outside of the housing 11. They therefore constitute connection pins in the sense of the present invention.

[0068] Near the connection pins, each adapter element 8 is provided with a radially extending collar 12 that cooperates with a constriction 13 of the housing's 11 cylindrical cavity to limit the motion of the adapter element 8 in its longitudinal direct and prevent the adapter element to fall out of the housing 11. The diameter of the constriction 13 is larger than that of the part of the adapter element 8 that passes through the constriction; this allows for a tilting and a radial translational motion of the adapter element 8 relatively to the housing 11. Yet, the difference between the diameter of the constriction 13 and the diameter of the part of the adapter element 8 that passes through the constriction also sets limits to the tilting and the translation of the adapter element 8.

[0069] At a location along each of the adapter elements 8 between the two contact pins 9, 10, there is provided a silicon rubber collar 14 that serves three functions: It acts as a seal of the adapter element 8 against the housing 11 in order to prevent a fluid from getting from one end to the other end of the adapter element 8; it acts as a dampening element for dampening the motion of the adapter element 8, for example under the influence of vibration; and it acts as a biasing element for biasing the adapter element 8 in a resting position. The resting position of the adapter element 8 is the central position shown in FIGS. 1 and 2 from which the adapter element 8 can, essentially by the same amount in opposite directions, be pivoted and moved translationally in a direction perpendicular to the longitudinal extension of the adapter element 8. In the longitudinal direction, the rubber collar 14 biases the adapter element 8 in the position of maximal distance from the lamella basket 6.

[0070] In FIG. 2, the adaptive connector 1 is joined with a counter connector 15 that has three connection sockets matching the connection pins 10 of the adaptive connector 1. Each connection sockets comprise a lamella basket 16 arranged in a lamella carrier 17 similarly to the lamella basket and the lamella carriers of the adaptive connector. The connection sockets are fixed in a shared housing 18 of the counter connector 15. The adapter element 8 of FIGS. 1 and 2 with the lamella baskets 6, 16 and the lamella carriers 5, 17 of the adaptive connector 1 and the counter connector 15 is also shown in FIG. 6.

[0071] As can be seen in FIG. 2, an O-ring 19 are provided to seal the counter connector 15 against the adaptive connector 1. Moreover, the counter connector 15 is provided with seals 20 that, when the counter connector 15 is attached to the adaptive connector 1, prevents fluids from getting from the outside of the housings 11, 18 into the connection socket of the counter connector 15. These seals 20 of the counter connector seal the outside walls parts of the counter connector 15 that, upon joining the counter connector 15 with the adaptive connector 1, enter into parts of the cavities of the adaptive connector 1 surrounding the connection pins 10, against the inside walls of these parts. Alternatively, the seals 20 can be provided on the adaptive connector 1.

[0072] An embodiment of the accommodating connector 1 with adapter elements that have connection lamella elements in the form of non-circularly-symmetrical connection sockets 21 on both ends is shown in FIGS. 3 and 4. As in the case of the adaptive connector 1 of FIGS. 1 and 2, the adaptive connector 1 of FIGS. 3 and 4 comprises three adapter elements 8 in a shared housing 11. Also as in the previous case, at a location along each of the adapter elements 8 between the two connection sockets 21 there is provided a silicon rubber collar 14 that serves as a seal between the adapter element 8 and the housing 11 in order to prevent a fluid from getting from one end to the other end of the adapter element 8, as a dampening element for dampening the motion of the adapter element 8, and as a biasing element for biasing the adapter element 8 in a central resting position and at an extreme position in the longitudinal direction of the adapter element 8.

[0073] Each connection socket 21 comprises two parallel one-sided lamella combs 22, which are welded to a lamella carrier 23. The lamellae of each comb 22 of the pair of combs 22 extend mainly along an inner wall of the lamella carrier 23 and towards the other one of the pair of combs 22. They can preferably be elastically biased against a matching non-circularly-symmetrical connection pin inserted between the pair of lamella combs 22. The ends 24 of busbars serve as such connection pins. These ends 24 each are essentially rectangular in cross section.

[0074] An alternative embodiment of an adapter element 8 is shown in FIG. 5. Unlike the adapter element 8 of FIGS. 3 and 4, the lamella combs are circularly-symmetrical lamella baskets 26. There is one lamella device at each end of the adapter element 8, each lamella device comprising the lamella basket 26 and a lamella carrier 23. This is also in contrast to the adapter element 8 in FIGS. 1, 2 and 6, where there are circularly-symmetrical contact pins 9, 10 at each end. FIGS. 5 and 6 both show how a contact pin 25, 9, 10 interacts with the lamella basket 26, 6, 16 when the contact pin 25, 9, 10 is slightly tilted relatively to the lamella basket 26, 6, 16. The lamellae are elastically biased against the contact pin 25, 9, 10, thereby compensates for the tilting and ensuring a reliable connection between the lamella basket 26, 6, 16 and the contact pin 25, 9, 10.

[0075] The adapter element 8 in FIGS. 7 and 8 is provided on one end with a lamella device in the form of a circularly-symmetrical stud 27 with a lamella basked 28 in a lamella carrier 29. The lamella device is mated with a matching circularly-symmetrical contact sleeve 30. On the other end, the adapter element 8 has the non-circularly-symmetrical socket 21 with a matching contact pin 24 similar to that shown in FIGS. 3 and 4. FIGS. 7 and 8 are different views of the same adapter element and matching contact sleeve 30 and contact pin 24; the view of FIG. 8 is rotated about the longitudinal axis of the adapter element by 90° relatively to the view of FIG. 7. As a result, the lamella comb 22 hidden in FIG. 7 behind the contact pin 24 can be seen in FIG. 8.

[0076] Finally, in FIG. 9 an adapter element 8 is shown that has contact jacks on both sides, namely a contact pin 33 on one and a contact sleeve 34 on the other end. The adapter's 8 contact pin 33 is slotted, the slot 35 extending perpendicularly to the paper plane and in longitudinal direction of the contact pin. Similarly, the contact sleeve 34 of the adapter is provided with four equidistant slots 36, two of which can be seen in the figure. Apart form the slots 35, 36, the contact pin 33 and the contact sleeve 34 are circularly-symmetrical in cross-section. The adapter's 8 contact pin 33 and contact socket 34 are mated with a corresponding non-slotted contact sleeve 37 and a non-slotted contact pin 38, respectively. These, too, are essentially circularly-symmetrical.

[0077] The features described in the above description, claims and figures can be relevant to the invention in any combination. Their reference numerals in the claims have merely been introduced to facilitate reading of the claims. They are by no means meant to be limiting.
