DETAILED DESCRIPTION OF THE INVENTION

(10) FIG. 1 is a side view of a plug connector according to a first embodiment of the invention. The plug connector has a housing 1, on which a first plug 21 and a second plug 22 are arranged.

(11) In this embodiment, the first plug 21 and the second plug 22 are configured as two-pole jack plugs. Jack plug connections are frequently used to transmit audio signals, particularly from electronic instruments such as electric guitars or electric basses. As depicted in FIG. 1a, the poles of the plugs 21 and 22 are formed by tips 21a, 21b [sic] and rear cylindrical portions 21b, 22b of the plugs 21, 22 (the so-called sheaths), which are electrically insulated from one another by insulation rings 21c, 22c. The sheaths 21b, 22b are grounded. In the interior of the plugs 21, 22, provision is made of an electrical connection (not shown) of the tips 21a, 22a of the plugs 21, 22 to the respective opposite ends of the plugs, which end in an electric contact. This can be discerned in the second plug 22 in FIG. 3. In that figure, the electric contact for the tip 22a of the second plug 22 bears the reference sign 24. The first plug 21 is constructed similarly and has, on its end opposite the tip 21a, an electric contact 23, which is connected to the tip 21a by an electrical connection in the interior of the first plug 21.

(12) The first plug 21 defines a plug-in direction A. In this embodiment, the first plug 21 is arranged on a first housing side 11a. The second plug 22 defines a plug-in direction B. The second plug 22 is arranged on a second housing side 11b, along which it is displaceable such that the relative position between the first plug 21 and the second plug 22 can be varied. Thus the relative positional relationship of the plug-in directions A and B to each other can likewise be varied.

(13) The plug connector shown in FIG. 1 can be used, for example, to connect two devices that are arranged adjacently to one another in such a way that they have two essentially parallel surfaces facing one another. If a socket is provided on each of these surfaces, then the plug connector can also be used for connecting the two devices if the sockets are arranged offset to one another by sliding the second plug 22 along the second housing side 11b.

(14) The height of the housing, i.e. the distance between the first housing side 11a and the second housing side 11b, is 10 mm in a preferred embodiment. The plug connector thus takes up little space and the devices to be connected can be arranged at very short distances from one another.

(15) The slidability of the second plug 22 is illustrated in FIGS. 2a and 2b, which show a perspective view from below of the plug connector from FIG. 1. In FIG. 2a, the second plug 22 is situated in a position that has a maximum offset between the plug-in directions A and B. In FIG. 2b, the plug 22 is situated in a position in which the plug-in directions A and B lie on a straight line. With this arrangement of the second plug 22, it is possible to connect two sockets that are aligned with one another.

(16) As can be discerned in FIGS. 2a and 2b, the end of the second plug 22 facing the housing 1 is mounted on the second housing side 11b in a guide slot 13, in which the slidable second plug 22 is guided. The guide slot 13 has a width that corresponds to the outer diameter of the second plug 22. This ensures that the second plug 22 can only be slid along the guide slot 13 and does not have any play in a direction perpendicular to that of the guide slot 13.

(17) FIG. 3 is an exploded view of the plug connector from FIG. 1. The housing 1 is formed by a first half shell 14 and a second half shell 15, which are inserted one on top of the other or glued or screwed together, or connected to one other in some other manner.

(18) The first half shell 14 and the second half shell 15 are made of a conductive material such as metal. The first plug 21 is fixedly connected by its sheath 21a to the first half shell 14. The (not shown in FIG. 3) electric contact 23 of the first plug 21 faces the interior of the first half shell 14. On the inside, the second half shell 15 has a displacement surface 12 along which the second plug 22 can be slid.

(19) In the embodiment shown FIG. 3, the second plug 22 is guided with its end arranged in the housing 1 by a cap 8, a ring 7, and a spring element 6. An insulating washer 5 is fixedly connected to the end of the second plug 22 arranged in the housing 1. The insulating washer 5 has a hole 51 in the center, through which the electric contact 24 of the second plug 22 protrudes in the assembled state. The cap 8 has a hollow cylindrical shape with an outer diameter that corresponds to the width of the housing 1 perpendicular to the guide slot 13.

(20) On the side facing the guide slot 13, the cap 8 has a radially inwardly projecting edge. The ring 7 is likewise of hollow-cylindrical design and has an outer diameter that corresponds to the inner diameter of the cap 8 on the radially projecting edge. The inner diameter of the ring 7 corresponds to the outer diameter of the second plug 22. On its end facing the insulating plate 4, the ring 7 has a radially outwardly projecting edge.

(21) An insulating plate 4 is arranged in the housing, on the side of the insulating washer 5 facing away from the second plug 22. The insulating plate 4 is made of an electrically insulating material, for example by a circuit board. A strip conductor 3, which is made of a conductive material, is provided on the side of the insulating plate 4 facing the second plug 22. In the exemplary embodiment shown, the strip conductor 3 is inlaid in a matching recess of the insulating plate 4 such that is flush with the surface of the insulating plate 4. However, the strip conductor 3 can also be imprinted or etched on the insulating plate 4.

(22) The strip conductor 3 is arranged on the insulating plate 4 in such a way that in the assembled state, it extends parallel to the guide slot 13. This arrangement ensures that the electric contact 24 of the second plug 22 is always in contact with the strip conductor 3 when the plug 22 is slid along the guide slot 13.

(23) To improve the electric contact further, the second plug 22 is additionally pre-tensioned toward the strip conductor 3, along the plug-in direction B. The pre-tension force is generated by the spring element 6. In the assembled state of the two housing shells 14 and 15, the side of the insulating plate 4 facing away from the strip conductor 3 abuts on the inside of the first half shell 14. At its housing-side end with the insulating washer 5 fixed thereon, the second plug 22 abuts on the insulating plate 4, wherein the electric contact 24 of the second plug 22 protrudes through the hole 51 of the insulating washer 5 and is in contact with the strip conductor 3.

(24) The spring element 6 is arranged on the plug axis of the second plug 22 and in engagement with the insulating washer 5. Between the spring element 6 and the second housing shell 15, provision is made of the ring 7 and the cap 8, which are likewise arranged on the plug axis of the second plug 22. The spring element 6 engages with the edge of the ring 7 and presses it towards the guide slot 13. In this process, the edge of the ring 7 engages with the edge of the cap 8. Because the cap 8 has an outer diameter that is larger than the width of the guide slot 13, the engaged assembly of the ring 7 and the cap 8 is pre-tensioned by the spring element 6 against the inner wall of the second half shell 15. The spring element 6 simultaneously pre-tensions the second plug 22 towards the insulating plate 4.

(25) The cap 8 and the ring 7 are made of a conductive material. The inner diameter of the ring 7 corresponds to the outer diameter of the second plug 22 in such a way that the sheath 22b of the second plug 22 is in conductive contact via the ring 7 and the cap 8 with the second half shell 15. The sheath 21b of the first plug 21 is in conductive contact with the first half shell 21 such that the sheaths 21a, 21b of the two plugs are conductively interconnected in the assembled state. The tip 22b of the second plug 22 is conductively connected via the electric contact 24 to the strip conductor 3. On the side facing away from the strip conductor 3, the insulating plate 4 has a hole 41 at a position that corresponds to the position of the electric contact 23 of the first plug 21. The strip conductor 3 extends over the hole 41 and is thus accessible from the side of the first plug 21. The electric contact 23 of the first plug 21 can be configured to fit the dimensions of the hole 41 so that the electric contact 23 can be plugged into the hole 41 in order to establish the contact with the strip conductor 3. As an alternative, the electric contact 23 can be soldered to or otherwise conductively connected to the strip conductor 3.

(26) With the plug connector constructed in this manner, a connection is created between the plugs 21 and 22 without the use of cables, which has a simple and mechanically sturdy construction and permits a variable arrangement of the plug-in directions A and B to one another. With appropriate selection of the dimensions of the individual parts described, the plug connector can also be produced without the use of connecting means such as screws or the like.

(27) In the embodiment described above, the displacement surface 12 is on the inside of the second half shell 15 parallel to the second housing side 11b, on which the second plug 22 is arranged. However, in principle it is also possible to configure the second housing side as non-parallel to the displacement surface 12. It is likewise conceivable to provide a construction in which the displacement surface 12, along which the plug 22 is slidably mounted, is on the outside of the housing. The crucial factor is merely that the second plug 22 is mounted slidably along a displacement surface.

(28) It is furthermore possible to embody the mounting of the second plug 22 in the housing in another fashion. The crucial factor is merely that contact between the strip conductor 3 and the electric contact 24 of the second plug 22 is ensured in every position of the second plug 22. For example, it is conceivable to connect the insulating washer 5 in a non-fixed manner to the second plug 22 and instead design the ring element 6 [sic] so that it engages radially, in regions, with the second plug 22 while it pre-tensions the second plug 22 towards the strip conductor. Nor is it absolutely necessary to provide the combination of the ring 7 and the cap 8 as long as it is ensured that the second plug 22 is still slidable along the displacement surface 12. For example, this could be achieved by omitting the ring 7 and designing the spring element 6 so that it engages directly with the radially inwardly projecting edge of the cap 8 for pre-tensioning the second plug 22 towards the strip conductor 3.

(29) FIG. 4 is a side view of a plug connector according to the second embodiment of the invention. Whereas the first housing side 11a and the second housing side 11b were arranged parallel to each other in the first embodiment, the first housing side 11a and the second housing side 11b in the second embodiment mutually form an angle . The angle is suitably an acute angle. The plug-in directions A and B of the plugs 21, 22 thus form an obtuse angle . This embodiment of the plug connector is an option when two devices to be interconnected are not arranged parallel to one another, for example on a crescent-shaped pedal board.

(30) The structure of the plug connector in FIG. 4 essentially corresponds to that of the first embodiment. As indicated by dashed lines, the strip conductor 3 is again arranged in the interior of the housing in such a way that it extends parallel to the guide slot 13 in order to ensure that the second plug 22 is in electric contact in every position in the guide slot 13. To this end, the insulating plate 4 is fastened, for example screwed, inside the housing 1 at a suitable point. As an alternative, the housing 1 can have corresponding formations on the inside on which the insulating plate 4 is fastened. In the second embodiment, the electric contact 23 of the first plug 21 is connected in a suitable fashion to the strip conductor 3, for example by a conductor element of appropriate length.

(31) FIG. 5 is a side view of a plug connector according to the third embodiment of the invention. Unlike the first embodiment, the first plug 21 is not arranged on the housing side 11, but on a longitudinal end portion of the housing 1. It is thus possible to create a plug connector that can provide mutually perpendicular plug-in directions A, B.

(32) The configuration of the plug connector from FIG. 5 corresponds to that of embodiment 1. Because the first plug 21 is mounted at a different position on the housing 1, the electric contact 23 is connected to the strip conductor 3 by provision of an appropriate conductor element. The arrangement of the insulating plate 4 and of the rest of the components corresponds to that of embodiment 1.

(33) FIG. 6 is a perspective view of a plug connector according to a fourth embodiment of the invention. In structure, the plug connector corresponds to the plug connector according to the first embodiment. In the case of the plug connector in FIG. 6, a washer 9 is applied, preferably molded, on the second plug 22, which extends radially outward from the second plug 22 and is positioned such that it abuts on the second housing side 11b. The washer 9 is preferably made of the same material as the sheath 22b of the second plug [22]. The stability and the guiding of the second plug 22 in the guide slot 13 can be improved with the washer 9.

(34) FIG. 7 is a view from above of an assembly of two effect devices 91, 92 and a plug connector according to this invention. On their left and right side surfaces, the effect devices 91, 92 each have a socket 91a, 92a, which is configured for receiving a jack plug corresponding to the plugs 21, 22. The relative position of the sockets 91a, 92a on the side surfaces of the effect devices 91, 92 is different. However, by using a plug connector according to this invention, the two effect devices can be arranged adjacently to each other in a space-saving manner by plugging the first plug 21 of the plug connector into the socket 91a of the one effect device 91 and by sliding the slidable second plug 22 such that it can be plugged into the socket 92a of the second effect device 92 when the effect devices 91, 92 are in parallel alignment.

(35) On their outwardly facing side surfaces in FIG. 6, the effect devices 91, 92 have additional sockets. With additional plug connectors, additional effect devices can be hooked up via these sockets. A signal chain can thus be formed out of any number of effect devices in a space-saving manner. If an angled arrangement of two effect devices is necessary, a plug connector according to the second embodiment of the invention can be used. Moreover, if an effect device has a socket on one of its end faces, a connection to an effect device with a socket on a longitudinal side of the effect device can be established with the plug connector according to the third embodiment.
