DETAILED DESCRIPTION

(9) In the following descriptions of the figures, the same elements or functions are marked with the same identifiers.

(10) FIGS. 1 and 2 show views of two complementary first and second plug connectors 10 and 20 in accordance with an embodiment of this invention. FIG. 3 shows the plug connector 20 shown in FIG. 2 as a two-part plug connector.

(11) The plug connector shown in FIG. 3 differs from the plug connector shown in FIG. 2 only by the fact, that for easier mounting onto e.g. a cable, it is constructed from two parts and it can be combined to form a complete plug connector by means of the connection elements 23. The connection elements 23 can be constructed in different ways, as a snap joint, as a screw joint, they can be glued, welded or connected in a different way provided the plug connector is firmly attached to the component.

(12) In the description below, the plug connector shown in FIG. 1 is described as the first plug connector 10 and the plug connector shown in FIG. 2 or FIG. 3 is described as the second plug connector 20, where the designations only serve to make the description easier. The reversed designations could be used equally well. The same applies for all of the components below described as first.

(13) In FIG. 1 a first plug connector 10 is shown, which at its end zone 101 can be connected to an electrical component, e.g. a cable, a socket or a different component. At its second end 102, the first plug connector 10 can be connected to a second end zone 202 of a second plug connector 20 shown in FIG. 2, which has a shape complementary to that of the first plug connector 10.

(14) For this, the body of the first plug connector 10 is equipped with the insertion aids 12 and 13 for the combination of the two plug connectors 10 and 20. The insertion aids 12 and 13, shown in FIG. 1, include the insertion ramps 13 on the body of the first plug connector 10 opposite to each other, which allow the bayonet-like locking, as well as a first guide element 12, which is located on the face of the first plug connector 10 in the form of a recess within the circumference, in order to accommodate the guide protrusion 22 of a second plug connector 20 and guide it into the insertion ramp 13. 13. The insertion aids 12 and 13 serve as the first part of a bayonet-like connection in conjunction with the second complementary part of the bayonet-like connection, which are shown in FIG. 2 correspondingly in the form of guide protrusions 22.

(15) The second plug connector 20, shown in FIG. 2 or 3, can at its first end zone 201, be connected to an electrical component, e.g. a cable. At its second end zone 202, its shape allows connection to the first plug connector 10. To do this, it is shaped as a complementary plug connector to the first plug connector 10 in such a way that it contains a second guide element 22 as the second part of the bayonet-like connection in the shape of a guide protrusion 22. In FIG. 2 or FIG. 3, two guide protrusions 22 are provided, which fit into the corresponding first guide element 12 on the first plug connector 10.

(16) In the embodiment shown in FIGS. 1 and 2 or 3, the first and the second plug connectors 10 and 20 are essentially cylindrical. However, any other suitable shape can be chosen, as long as the connection can be made as described in this invention.

(17) In FIG. 1, two insertion ramps 13 and two first guide elements 12 are shown. Depending on the application, it is, however, possible to provide only one insertion ramp 13 and one first guide element 12 or more than two insertion ramps 13 or first guide elements 12. The second plug connector 20 for the connection to the first plug connector 10 is chosen correspondingly.

(18) The first guide elements 12, shown in FIG. 1, are shaped in such a way that they form recesses in the circumference at the face of the first plug connector 10, so that a second complementary guide element 22, e.g. a guide protrusion, can be guided by it in order to then be inserted into the insertion ramp 13. The first guide element 12 in the form of a recess, has the advantage that even in its end position it will not, or only negligibly, protrude further from the plug connector arrangement than the second guide element 22 inserted via the bayonet-like connection of the second plug connector 20.

(19) In addition to the space-saving bayonet-like connection, the first plug connector 10, shown in FIG. 1, provides at its face four first locking elements 11 for the secure fixation of the connection, which are arranged in pairs side-by-side and opposite to the other two locking elements 11. The first locking elements 11 are arranged at the face or close to it, i.e. at a small distance from the face of the second end 102 of the first plug connector 10, in order to lock in the plugging direction to the corresponding complementary second locking elements 21 of the second plug connector 20. The arrangement of the locking elements 11 depends on the application and is not limited to the locking elements 11 being located directly at the face of the second end 102 on the first plug connector 10. Rather, a distance to the face can be specified, as long as the complementary locking element 21 has an appropriate shape to achieve the same locking effect.

(20) The second plug connector 20, shown in FIG. 2 or FIG. 3, has at a distance from its second end zone 202, at which the guide protrusions 22 are located, the second locking elements 21 complementary to the locking recesses 11, shown in FIG. 1, which have the shape of locking protrusions 21. The second locking elements 21 are arranged in such a way on the second plug connector in FIG. 2 that, in the plugging direction, i.e. the direction, in which the first plug connector is combined with or disconnected from the second plug connector (see reference mark 40 in FIG. 4), it can lock to the first locking element on the first plug connector 10.

(21) The shape of the locking elements 11 and 21 is chosen so that a firm, largely play-free connection is achieved after locking together. Shapes like triangles, trapezes, nubs or others can be chosen to enable the locking together. Advantageous is a choice of shape which can be easily manufactured, e.g. by injection molding.

(22) The plug connector material is chosen so that, in radio frequency applications, intermodulation is prevented or that it is resistant to intermodulation. Furthermore, the material should provide a certain elasticity because, in order to avoid overlifting with the bayonet-like connection, an elastic deformation and return to the original form is required for at least the guide element 22 in the form of a guide protrusion. Equally, a locking element can be constructed elastically. This is the obvious solution if the guide protrusion 22 and the locking protrusion 21 are located at the same plug connector. In this case, it is also advantageous if the guide protrusion 22 is closer to the second end zone 202 of the plug connector than the locking protrusion 21, which, in turn, is arranged at a distance from the guide protrusion 22. When combining the two plug connectors, as shown in FIG. 4, the guide protrusions 22 of the second plug connector 20 are inserted into the guide recesses 12 in the first plug connector 10. Then the plug connectors 10 and 20 are twisted with respect to each other as shown in FIG. 5, so that the guide protrusions 22 are inserted into the insertion ramps 13 until the locking elements 21 of the second plug connector 20 meet the face of the first plug connector 10. This is shown in FIG. 6. In FIG. 6, it is shown that the guide protrusions 22 have not yet reached an end position and the locking elements 11, 21 have not yet locked together. In order to reach the end position or to achieve the locking, the two plug connectors are rotated further. When doing this, the distance between the guide protrusions 22 and the locking protrusions 21 is elastically expanded on account of the material between the insertion ramp 13 and the face of the first plug connector 10, which in the rotation direction corresponds to a wedge. When the end position is reached, as shown in FIG. 7, the material of the second plug connector 20 can elastically return to its original shape while the locking elements 21 lock to each other. Depending on the application and the manufacturing tolerances, a residual stress can remain in the guide protrusions 22 in the axial direction, i.e. in the plugging direction 40. On account of the elastic deformability of the guide protrusions 22 and/or the locking elements 21, overlifting can be avoided inside the plug connectors 10, 20, i.e. when the components are electrically connected to each other, which results in a higher reliability.

(23) In FIG. 7, a plug connector arrangement 30 is shown, in which the first plug connector 10 has been connected to the second plug connector 20 and where the end position has been reached, i.e. the locking elements 11 and 21 are locked to each other. On account of the space-saving bayonet-like connection and the locking elements arranged in the plugging direction, the plug connector arrangement 30 requires very little space and can be easily mounted. For this reason, several plug connector arrangements can be located side by side closely spaced, which in turn results in a cost saving.

(24) The plug connector arrangement is separated by reversing the mounting process. The lock connection can be separated by applying a force, which is determined by the corresponding choice of the locking elements 11 or 21. On account of the elastic deformability of the guide element 22 or the locking elements 21 and/or of the material of the plug connector, no overlifting occurs at the electrical components during the separation process of the plug connector arrangement.

(25) In the figures, concretely a first and a second plug connector, guide element and locking element are referred to. This concretization is only used to achieve a better description. The designations first and second are therefore interchangeable.

(26) On account of the axial combination of the plug connectors, a minimized space requirement has been realized without detrimental effect on the secure fixation of the plug connectors.
