Description

The invention relates to an electrical assembly connector having an inner conductor contact element and a dielectric, the inner conductor contact element extending through the dielectric along a longitudinal axis of the dielectric, according to the preamble of claim 1.

The invention also relates to an electrical assembly connection and an assembly arrangement.

For signal transmission between electrical circuit boards, electrical assembly connectors can be used (in particular also known by the terms “circuit board connector” and “board-to-board connector”). As a rule, an end-face contact connection is provided between inner conductor contact elements of the assembly connector and mating connectors of the circuit boards. The contact connection can preferably be implemented via spring contact pins (also known under the term "pogo pin").

If there is a high number of signal connections to be made between the circuit boards, a correspondingly high number of assembly connectors must be used. The high mechanical contact pressure that acts on the printed circuit boards as a result can, however, be problematic. The possible number of assembly connectors - and thus the possible number of transmission channels between the circuit boards - can therefore be limited in practice.

Another problem that is associated with the constant miniaturization of electronic circuits and their assemblies is an axial offset (e.g. of up to one millimeter or more) between the printed circuit boards to be connected to one another or their mating connectors. In the future, the assembly connectors must increasingly be able to compensate for an axial offset between the mating connectors to be connected to one another.

In view of the known prior art, the object of the present invention is to provide an electrical assembly connector which preferably exerts no or only negligible contact pressure on the assemblies to be connected and which is preferably able to compensate for an axial offset between the assemblies.

The present invention is also based on the object of providing an electrical assembly connection which preferably exerts no or only negligible contact pressure on the assemblies to be connected and which is preferably able to compensate for an axial offset between the assemblies.

It is also an object of the invention to provide an improved assembly arrangement.

The object is achieved for the electrical assembly connector with the features listed in claim 1. With regard to the electrical assembly connection, the object is achieved by the features of claim 9. With regard to the assembly arrangement, the object is achieved by claim 15.

The dependent claims and the features described below relate to advantageous embodiments and variants of the invention.

An electrical assembly connector is provided, having an inner conductor contact element and a dielectric, the inner conductor contact element extending through the dielectric along a longitudinal axis of the dielectric. In the area of a first end, the inner conductor contact element has a first contact section for contacting a first electrical mating connector of a first electrical assembly assigned to the first end. The first contact section is designed to enable a lateral or radial / lateral contact connection with the first mating connector.

In particular, it can be provided that there is no end-side contact between the first contact section and the first mating connector.

The electrical assembly connector is particularly advantageously suitable as a circuit board connector in order to connect several electrical circuit boards, in particular precisely two electrical circuit boards, to one another for the exchange of electrical data and / or supply signals. The first assembly can thus preferably be a first electrical circuit board (also referred to as a “printed circuit board, PCB”) and the second assembly, which is also mentioned below, can be a second electrical circuit board. In principle, however, any electrical assemblies (including different types of assemblies) can be connected to one another with the assembly connector according to the invention, for example also integrated circuits accommodated in a chip housing, or electrical connectors or adapters.

A force-fit and / or form-fit lateral contact connection between the first contact section and the first mating connector can be provided.

Due to the lateral contact connection according to the invention, an axial contact pressure on the electrical assemblies can advantageously be avoided. As a result, the mechanical load on the electrical assemblies involved, in particular the printed circuit boards, can be neglected even with a large number of assembly connectors used.

According to the invention it is provided that the lateral contact connection and / or the dielectric are designed to enable tilting and / or an axial offset of the inner conductor contact element relative to the longitudinal axis of the dielectric.

Thus, according to the invention, the contact pressure between the electrical assemblies to be connected can advantageously be reduced at the same time, with an axial offset of the assemblies also being able to be compensated for at the same time.

In an advantageous development of the invention, it can be provided that the inner conductor contact element has a second contact section in the region of a second end for contacting a second electrical mating connector of a second electrical assembly assigned to the second end, the second contact section being designed to provide a lateral contact connection with to enable the second mating connector.

The inner conductor contact element thus preferably has a contact section at each of its two ends and can therefore advantageously be used for the electrical connection of two mating connectors of two electrical assemblies. In principle, however, it can also be provided that the inner conductor contact element is connected directly to the second assembly with one of its two ends, for example soldered, (cold) welded or pressed or crimped.

In particular, it can be provided that there is no end-side contact between the second contact section and the second mating connector.

A force-fit and / or form-fit lateral contact connection can be provided between the second contact section and the second mating connector.

According to a development of the invention it can be provided that the inner conductor contact element is designed as a flat sheet metal part or as a round contact pin.

In principle, the inner conductor contact element can be produced by any desired shaping method, such as, for example, stamping, bending, deep drawing and / or injection molding. Subtractive methods, such as, for example, etching and / or laser cutting, may also be suitable for producing the inner conductor contact element. The sheet metal part can be a stamped and bent part, for example.

In particular if the inner conductor contact element is designed as a flat sheet metal part, the assembly connector according to the invention can be manufactured easily and inexpensively, which can be a decisive advantage in particular in the context of mass production.

The inner conductor contact element is preferably designed in one piece. The inner conductor contact element can, however, also be configured in several parts, in particular in two or three parts, for example in order to realize the articulated connection described below.

According to a further development of the invention, it can be provided that the inner conductor contact element is designed as an inelastic, rigid component, in particular between the two contact sections.

The deformability or elasticity of the inner conductor contact element can be selected such that the inner conductor contact element cannot bend between its two ends to support tilting relative to the longitudinal axis of the dielectric without experiencing an irreversible, plastic deformation.

According to a further development of the invention, however, it can also be provided that the inner conductor contact element is designed to be elastic, in particular between the two contact sections, at least in a central region.

It can thus be provided that the inner conductor contact element can bend reversibly between its two ends in order to enable or support the tilting relative to the longitudinal axis of the dielectric.

According to a further development of the invention, it can also be provided that the inner conductor contact element has an articulated connection between the two contact sections in a central region.

The articulated connection can be formed, for example, by a two-part construction of the inner conductor contact element.

It can be provided that the inner conductor contact element is basically designed to be inelastic, the inner conductor contact element having a pivotable or bendable central region. The pivotable or bendable central region is thus able to enable or support tilting of the inner conductor contact element in the dielectric.

The pivotable or bendable central area can, for example, be made thinner than the rest of the contact element and thus be sufficiently elastic.

In a further development of the invention it can be provided that the first contact section of the inner conductor contact element and / or the second contact section of the inner conductor contact element has two or more spring tabs curved outwards or inwards.

The inner conductor contact element can preferably have exactly two spring tabs, in particular (but not exclusively) if the inner conductor contact element is designed as a flat sheet metal part. The two spring tabs can preferably be arranged in the manner of pliers or in the manner of a fork contact with one another.

The inner conductor contact element can, however, also have more than two spring tabs, preferably three spring tabs, very particularly preferably four spring tabs. In principle, even more spring tabs can be provided. If more than two spring tabs are provided, the inner conductor contact element can in particular (but not exclusively) be designed as a round contact pin which is axially slotted at its ends in order to form the spring tabs.

Overall, the spring tabs can form a shape that is as spherical as possible, preferably a circle or an ellipse (in the case of two spring tabs) or a hollow sphere or a hollow ellipsoid (in the case of more than two spring tabs).

The spring tabs can form a radial expansion of the inner conductor contact element, which preferably forms the contact section.

By means of the spring tabs, in particular the spherical or radial component of the spring tabs, a lateral contact connection can be created in a particularly advantageous manner which enables the inner conductor contact element to be twisted or even axially offset.

In a development of the invention it can be provided that the first contact section of the inner conductor contact element and / or the second contact section of the inner conductor contact element is designed as a sleeve-shaped spring cage.

In particular, an axially slotted spring cage can be provided.

The spring cage can have a radial bead or a radial course which extends in the direction of the central axis of the inner conductor contact element. This can improve the lateral contact with the mating connector.

It should be mentioned that the first contact section and the second contact section of the inner conductor contact element can be designed differently. However, the contact sections are preferably of identical design.

In an advantageous development of the invention it can be provided that the dielectric has a suitable elasticity in order to enable the tilting and / or the axial offset of the inner conductor contact element relative to the longitudinal axis of the dielectric.

The dielectric can preferably be formed from an elastomer. The dielectric can be formed from a silicone, for example.

The material of the dielectric is preferably so soft that the inner conductor contact element can give way to the mating connectors in the dielectric so that the inner conductor contact element can align itself eccentrically and / or obliquely in the dielectric when it is plugged in.

The dielectric can also have material recesses or slots that run radially around the longitudinal axis of the dielectric at least in sections (in particular, partially ring-shaped and / or ring-shaped slots). The slots can run through the dielectric starting from an inner wall of the dielectric and / or starting from an outer wall of the dielectric. Recesses or slots within the dielectric can also optionally be provided be. The recesses or slots can be made in the dielectric along exactly one or along a plurality of axial sections or completely (for example evenly) distributed along the longitudinal axis over the dielectric. The recesses or slots are preferably formed over the entire circumference, that is to say each run completely around the dielectric. One or more slots running spirally along the longitudinal axis of the dielectric can also be provided.

In an advantageous embodiment of the invention, it can also be provided that the dielectric is pivotable relative to its surroundings, in particular within a bore of the outer jacket mentioned later, at least along an angular segment. For this purpose, the dielectric can, for example, have an outer ring, in particular an outer ring arranged centrally along the longitudinal axis, which contacts a wall surrounding the dielectric (for example the inner surface of the mentioned bore in the outer jacket) and thereby forms a center of rotation for the dielectric.

In an advantageous embodiment of the invention it can also be provided that the dielectric is formed in several parts. The dielectric can in particular be designed in two parts and have an inner part and an outer part which surrounds the inner part in a ring shape. The inner part preferably has a receptacle for the inner conductor contact element. A radial gap can be provided between the inner part and the outer part. The inner part can be pivotably or rotatably connected to the outer part via a membrane. The membrane can preferably be arranged in a central section, particularly preferably exactly in the middle along the longitudinal axis of the dielectric. The inner part and the outer part can be formed from different materials. The inner part and the outer part are preferably formed from the same material. The outer part preferably makes direct contact with the bore in the outer jacket.

In a further development of the invention it can be provided that the dielectric has a funnel-shaped recess widening in the direction of the respective end in the area of at least one of its two ends in order to tilt and / or to axially offset the inner conductor contact element relative to the longitudinal axis of the Allow dielectric.

A funnel-shaped section of the dielectric can be particularly suitable in combination with an elastic inner conductor contact element or with an inner conductor contact element with an articulated connection in order to provide the inner conductor contact element with sufficient space in the area of one or both ends for tilting and / or for an axial offset.

The invention also relates to an electrical assembly connection, having at least one electrical assembly connector according to the statements above and below. The electrical assembly connection also has the mating connector or connectors assigned to a respective assembly connector.

The electrical assembly connection is preferably designed as a circuit board connection and comprises at least one assembly connector configured as a circuit board connector and the mating connectors of the circuit boards to be connected to one another by means of the circuit board connector.

In an advantageous development of the invention, it can be provided that more than one assembly connector is provided for the respective contacting of at least one associated mating connector, preferably two assembly connectors or more assembly connectors, particularly preferably 16 assembly connectors or more assembly connectors, very particularly preferably 128 assembly connectors or more assembly connectors, For example, also 256 assembly connectors or more assembly connectors or 512 assembly connectors or even more assembly connectors.

The invention is particularly suitable for use with a large number (in particular several hundred) assembly connectors, since the contact pressure against the assemblies, for example printed circuit boards, according to the invention can be negligibly low.

Preferably, each of the assembly connectors connects a first mating connector of the first assembly to a second mating connector of the second assembly. A number of mating connectors corresponding to the number of module connectors can thus be provided on each of the two modules. All module connectors and all mating connectors involved together preferably form the module connection according to the invention.

According to a further development of the invention it can be provided that the assembly connection has at least one electrically conductive outer jacket which envelops exactly one of the assembly connectors, a group of assembly connectors or all assembly connectors along the longitudinal axis. All assembly connectors are preferably accommodated in an outer jacket.

In an advantageous embodiment of the invention, it can be provided, in particular, that the assembly connection has an outer jacket that jointly accommodates all assembly connectors (for example in the manner of an outer housing).

The assembly connectors can be received in respective slots of the outer jacket, preferably in respective bores of the outer jacket.

The outer jacket is preferably designed in one piece and has the bores for the assembly connectors.

The outer jacket is preferably formed from a metal or from a metallized plastic.

The outer jacket can be fastened to at least one of the assemblies, preferably to both assemblies, for example it can be screwed to the assembly or assemblies.

The outer jacket can advantageously provide an outer conductor for the inner conductor contact elements of the assembly connector, which outer conductor is able to electromagnetically shield the inner conductor contact elements.

In particular (but not exclusively) if an outer sheath or some other outer conductor is provided (possibly also a multi-part outer sheath, e.g. a respective outer sheath for individual inner conductor contact elements or groups of inner conductor contact elements), the assembly connection can be particularly advantageous for use in high-frequency technology suitable.

In an advantageous development of the invention it can be provided that the mating connector has a contact sleeve.

The contact sleeve of the mating connector can be designed to accommodate the outwardly curved spring tabs of the inner conductor contact element for contacting the spring tabs with an inner surface of the contact sleeve to form the lateral contact connection.

This enables, on the one hand, a suitable possibility for tilting and / or an axial offset of the inner conductor contact element and, on the other hand, self-centering of the contact section of the inner conductor contact element in the mating connector.

It can be provided that the contact sleeve has a radial bead or a radial profile which extends in the direction of the central axis of the mating connector. As a result, the lateral contact with the contact section of the inner conductor contact element can be further improved.

The combination of a contact sleeve of the mating connector with outwardly curved spring tabs of the inner conductor contact element is particularly preferred.

The contact sleeve of the mating connector can alternatively or additionally also be designed to penetrate to form the lateral contact connection between the inwardly curved spring tabs of the inner conductor contact element for contacting the spring tabs with an outer surface of the contact sleeve.

In a further development of the invention it can also be provided that the mating connector has a mating contact with a spherical contact area which is designed to penetrate into the sleeve-shaped spring cage of the inner conductor contact element to form the lateral contact connection.

The spring cage of the inner conductor contact element can thus advantageously encompass the spherical contact area of the mating connector, whereby tilting and / or an axial offset of the inner conductor contact element can also be made possible.

The spherical contact area of the mating connector can be formed in particular in the area of the front, free end of a pin contact of the mating connector. The pin contact can preferably be produced as a turned part. The pin contact can, however, also be produced as a stamped and bent part or in some other way. The pin contact can also be designed to be hollow or at least have an inner bore adjacent to the assembly for simplified assembly, for example to reduce the size of a soldering surface.

It should be mentioned that the first mating connector and the second mating connector can be designed differently. However, the mating connectors are preferably of identical design. The mating connectors that are assigned to different inner conductor contact elements can also be different from one another. However, it is particularly preferred that all mating connectors and all inner conductor contact elements are each designed identically.

According to a development of the invention it can be provided that the lateral contact connection forms a latching connection.

For example, the contact sleeve of the mating connector can have a groove into which a web or a bead of the contact section of the inner conductor contact element can penetrate and latch. It can also be provided that the sleeve-shaped spring cage of the inner conductor contact element has a groove into which a web or a bead of the mating connector can penetrate and lock.

Particularly preferably, it can be provided that a contact sleeve of the mating connector has an inwardly protruding bead at an axial position along a central axis of the mating connector (for example in a central area or in the area of an axial end of the mating connector), in particular a bead extending in an annular manner along the inner surface of the contact sleeve Bead behind which the spring tabs of the inner conductor contact element can snap into place. The spring tabs are thus able to mechanically relax completely or at least partially behind the bead, as a result of which the spring force of the spring tabs mechanically secures the contact connection. In particular, it can be provided that the bead is arranged in the area of one of the axial ends of the mating connector in such a way that the bead, depending on the mounting direction of the mating connector, can form the latching connection together with the spring tabs of the inner conductor contact element (if the bead is in the area of the facing away from the assembly axial end of the mating connector is arranged) or is not able to form a latching connection (if the bead is arranged in the region of the axial end of the mating connector facing the assembly). As a result, the production costs for the mating connector can be further reduced, since in the best case only one mating connector type has to be produced, regardless of whether a snap-in connection is desired or not.

The holding force of the assembly connection and the mechanical stability of the connection between the assemblies can thus be significantly improved by the latching connection. The connection can thus preferably no longer be unintentionally released.

In particular, it can also be provided that only some of the contact connections form a latching connection. For example, it can be advantageous if only the contact connections in the area of the first assembly or in the area of the second assembly form a latching connection. Optionally - insofar as the bead is arranged in the area of one of the axial ends of the mating connector, as described above - the mating connector can then preferably be mounted identically, but in different orientations on the respective assembly.

In principle, however, a latching connection can also be dispensed with.

The axial lengths of the mating connectors on the contact sections of the inner conductor contact elements are preferably matched to one another, so that no additional shaped elements are required in the dielectric.

The invention also relates to an assembly arrangement having a first electrical assembly and a second electrical assembly. To connect the two assemblies, the assembly arrangement has an electrical assembly connection in accordance with the explanations above and below.

The mating connectors can be mechanically and electrically connected to the assembly assigned to them, in particular soldered, pressed or screwed. The mating connectors can be electrically connected to the respective signal and / or supply lines of the assembly assigned to them.

The assembly arrangement is preferably designed as a circuit board arrangement, the first electrical assembly as a first circuit board and the second electrical assembly as a second circuit board. The invention is particularly advantageous for connecting two printed circuit boards.

According to the invention, an inexpensive board-to-board connection can be created which does not exert any permanent forces on the printed circuit boards to be connected. At the same time, an axial offset of an outer conductor housing and a circuit board structure can be compensated for.

The invention can be particularly advantageously suitable for use in mobile radio technology, in particular for the connection of printed circuit boards of mobile radio base stations. For example, for 5G cellular base stations there may be a requirement to provide several hundred data channels between their electrical circuit boards. In principle, however, the invention can advantageously be used in all of electrical engineering, for example also in the vehicle sector.

Features that have been described in connection with the assembly connector according to the invention can of course also be advantageously implemented for the assembly connection and the assembly arrangement - and vice versa. Furthermore, advantages that were mentioned in connection with the assembly connector according to the invention can also be understood in relation to the assembly connection and the assembly arrangement - and vice versa.

In addition, it should be pointed out that terms such as “comprising”, “having” or “with” do not exclude any other features or steps. Furthermore, terms such as “a” or “the” which refer to a single number of steps or features do not exclude a plurality of features or steps - and vice versa.

The first mating connector, the second mating connector and / or the outer jacket can also be part of the electrical assembly connector.

In a puristic embodiment of the invention, however, it can also be provided that the features introduced in the invention with the terms “comprising”, “having” or “with” are conclusively enumerated. Accordingly, one or more lists of features can be regarded as complete within the scope of the invention, for example, considered for each claim. The invention can consist exclusively of the features mentioned in claim 1, for example.

It should also be emphasized that the values and parameters described here have deviations or fluctuations of ± 10% or less, preferably ± 5% or less, more preferably ± 1% or less, and very particularly preferably ± 0.1% or less of the respectively named Include value or parameter, provided that these deviations are not excluded when implementing the invention in practice. The specification of ranges by start and end values also includes all those values and fractions that are enclosed by the respective named range, in particular the start and end values and a respective mean value.

Exemplary embodiments of the invention are described in more detail below with reference to the drawing.

The figures each show preferred exemplary embodiments in which individual features of the present invention are shown in combination with one another. Features of an exemplary embodiment can also be implemented separately from the other features of the same exemplary embodiment and can accordingly be easily combined by a person skilled in the art to form further meaningful combinations and sub-combinations with features of other exemplary embodiments.

In the figures, functionally identical elements are provided with the same reference symbols.

Figure 1 shows an assembly arrangement 1 with a first electrical assembly 2 and a second electrical assembly 3, which are electrically connected to one another via an assembly connection 4 for the exchange of data signals and / or supply signals. The two assemblies 2, 3 are indicated merely by way of example and without further details, the first assembly 2 in FIG Figure 1 for a better illustration of the assembly connection 4 is also shown partially in section.

In principle, the invention is suitable for use with any assemblies 2, 3, but in particular for use with electrical circuit boards. The first assembly 2 is thus preferably designed as a first circuit board and the second assembly 3 as a second circuit board.

The electrical assembly connection 4 has a plurality of electrical assembly connectors 5, each of which has a first mating connector 6 of the first assembly 2 with a second mating connector 7 (see e.g. Figure 2 ) of the second assembly 3 with each other. The assembly connection 4 can basically have any number of assembly connectors 5 with the respectively corresponding mating connectors 6, 7, in particular two assembly connectors 5 or more assembly connectors 5, particularly preferably 16 assembly connectors 5 or more assembly connectors 5, very particularly preferably 128 assembly connectors 5 or more assembly connectors 5, for example also 256 assembly connectors 5 or more assembly connectors 5 or 512 assembly connectors 5 or even more assembly connectors 5. The invention is particularly advantageous for producing a large number of connections or transmission channels between the two assemblies 2, 3. If necessary, however, a module connection 4 with only a single module connector 5 and the correspondingly corresponding mating connectors 6, 7 can also be provided.

The assembly connectors 5 are advantageously accommodated in a common, electrically conductive outer jacket 8. In the exemplary embodiments, the outer jacket 8 has respective bores 9 for this purpose. The outer jacket 8 is preferably formed from a metal or from a metallized plastic and is mechanically and electrically connected to the two assemblies 2, 3. The outer sheath 8 can serve as a common outer conductor for the assembly connectors 5. In principle, several outer jackets 8 can also be provided, which enclose individual assembly connectors 5 and / or groups of assembly connectors 5 along their longitudinal axis L.

Figure 2 FIG. 11 shows a further perspective illustration of the assembly arrangement 1 of FIG Figure 1 . The outer jacket 8 is for better illustration in Figure 2 hidden or only indicated by dashed lines. Figure 3 FIG. 11 shows a sectional side view of the assembly arrangement 1 of FIG Figure 1 .

How with the Figures 1 to 3 As can be clearly seen, each assembly connector 5 has an inner conductor contact element 10 and a dielectric 11. The inner conductor contact element 10 extends along a longitudinal axis L of the dielectric 11 through the dielectric 11. For better illustration, the dielectric 11 is shown in FIG Figure 2 hidden for two of the middle assembly connectors 5. For the complete representation of one of the inner conductor contact elements 10, one of the first mating connectors 6 and one of the second mating connectors 7 are also shown in FIG Figure 2 hidden. For reasons of illustration of the inner conductor contact elements 10 are also shown in FIG Figure 1 two of the first mating connectors 6 hidden.

The inner conductor contact element 10 has, in the region of a first end, a first contact section 12 for contacting a first mating connector 6 of the first assembly 2 assigned to the first end. The first contact section 12 is designed to enable a lateral contact connection with the first mating connector 6. The inner conductor contact element 10 also has, in the region of a second end, a second contact section 13 for contacting a second mating connector 7 of the second assembly 3 assigned to the second end. The second contact section 13 is also designed to enable a lateral contact connection with the second mating connector 7.

Basically, it should be mentioned that the inner conductor contact element 10 can also have only one of the contact sections 12, 13. The inner conductor contact element 10 can, for example, be fastened with one end directly to one of the assemblies 2, 3, for example soldered, welded or screwed. However, this is not a preferred use of the assembly connector 5. Two contact sections 12, 13 are preferably provided. The first contact section 12 and the second contact section 13 can be different or identical. The first mating connector 6 and the second mating connector 7 can also differ or be identical.

It is provided that the lateral contact connection and / or the dielectric 11 are designed to enable tilting and / or an axial offset of the inner conductor contact element 10 relative to the longitudinal axis L of the dielectric 11. In Figure 3 Examples of two assembly connectors 5 with a tilted inner conductor contact element 10 (first assembly connector 5 from the right and second assembly connector 5 from the left) and one assembly connector 5 with an axially offset inner conductor contact element 10 (second assembly connector 5 from the right) are shown.

In the embodiment of Figures 1 to 3 the inner conductor contact element 10 is designed as a flat, rigid or inelastic sheet metal part. This variant is particularly preferred due to the simple production of such an inner conductor contact element 10, for example as a stamped and bent part. In principle, however, the inner conductor contact element 10 can also have a different geometry and, for example, be designed as a round contact pin and / or elastic or bendable, which will be shown below.

According to the first embodiment of the Figures 1 to 3 the first contact section 12 and the second contact section 13 of an inner conductor contact element 10 each have two outwardly curved spring tabs 14 which are tong-shaped or shaped like a fork contact. The mating connectors 6, 7 each have a corresponding contact sleeve 15 which is able to accommodate the outwardly curved spring tabs 14 of the contact sections 12, 13 of the inner conductor contact element 10 in order to form the lateral contact connection. The spring tabs 14 thus contact an inner surface of the contact sleeve 15.

To accommodate the inner conductor contact element 10, the dielectric 11 has a central recess; in the embodiment of Figures 1 to 3 a slot 16 (see also Figure 4a ) to accommodate the flat inner conductor contact elements 10.

The inner conductor contact element 10 can be positively received in the dielectric 11 for loss-free fixation, for which, for example, protrusions and recesses of the inner conductor contact element 10 and the recess in the dielectric 11 can advantageously be combined, as in the sectional view of FIG Figure 3 is easily recognizable.

Optionally, a snap connection or latching connection 17 can be provided between the contact sections 12, 13 and the mating connectors 6, 7. For example, all or some of the contact connections can have a latching connection 17. In the embodiments of Figures 1 to 7 a latching connection 17 is provided between the second mating connector 7 of the second assembly 3 and the second contact sections 13 of the inner conductor contact elements 10 (see in particular the enlarged section of a second mating connector 7 in FIG Figure 3 ). The contact sleeves 15 of the second mating connector 7 have, in the area of an axial end facing away from the second assembly 3, a radially or annularly circumferential bead 18 on the inner surfaces, behind which the outwardly curved spring tabs 14 are able to snap in. In the embodiment of Figures 1 to 3 the first mating connector 6 and the second mating connector 7 are each designed identically to reduce manufacturing costs. At the same time, the first mating connectors 6 are fastened to the first assembly 2 with the axial end having the bead 18. This "upside down" arrangement (see also the two enlarged sections in Figure 3 ) Finally, no latching connection 17 is formed. A latching connection 17 can thus optionally be formed solely through the orientation of the contact sleeves 15 or not.

Due to the spherical, lateral contact connection between the mating connectors 6, 7 and the contact sections 12, 13 of the inner conductor contact elements 10, rotation or tilting and even an axial offset or eccentricity of the inner conductor contact element 10 in the connection between the mating connectors 6, 7 is possible , whereby an axial offset between the two assemblies 2, 3 and / or the mating connectors 6, 7 to be connected to one another is advantageously made possible.

It can be provided that the dielectric 11 has a suitable elasticity in order to enable the tilting or the axial offset of the inner conductor contact element 10. For this purpose, a dielectric 11 can be formed, for example, from an elastomer with sufficiently elastic properties. A silicone in particular can be suitable.

As an alternative or in addition, it can also be provided that the dielectric 11 has material recesses 19 that run radially around the longitudinal axis L at least in sections, as in FIG Figure 4a indicated. The material recesses 19 can be designed to be completely ring-shaped or only partially ring-shaped. The material recesses 19 can also only be provided in sections in the dielectric 11. The material recesses 19 can also run spirally. In Figure 4a the material recesses 19 are formed starting from the outer surface of the dielectric 11. As an alternative or in addition, the material recesses 19 can, however, also be provided on the inner surface of the dielectric 11 and / or completely within the dielectric 11.

In order to enable tilting, provision can also be made for the dielectric 11 to be pivotable in the bore 9 or in the outer jacket 8 at least along an angular segment. An exemplary implementation of a pivotable dielectric 11 is shown in FIG Figure 4b shown. The pivotable dielectric 11 can have an outer ring 20, in particular an outer ring 20 arranged centrally along the longitudinal axis L, which contacts the outer jacket 8 and thereby forms a center of rotation for the dielectric 11 within the outer jacket 8.

Another possibility for designing a dielectric 11 is shown in FIG Figure 4c shown. The dielectric 11 of the Figure 4c is designed in two parts and has an inner part 11a and an outer part 11b which surrounds the inner part in an annular manner. The receptacle for the inner conductor contact element 10, for example the slot 16, is formed in the inner part 11a. An air gap is provided between the inner part 11a and the outer part 11b (which can optionally also be filled by a further material, in particular a soft or elastic material). The inner part 11a is pivotably or rotatably connected to the outer part 11b via a membrane 21 (preferably in a central section, particularly preferably exactly in the middle along the longitudinal axis L). The inner part 11a is thus pivotable relative to the outer part 11b. The inner part 11a and the outer part 11b can be formed from different materials, but are preferably formed from the same material. The outer part 11b preferably makes direct contact with the bore 9 of the outer jacket 8.

Figure 5 shows a second exemplary embodiment of an assembly arrangement 1 according to the invention. The first assembly 2 and two of the first mating connectors 6 are shown in FIG Figure 5 hidden for better representation.

The embodiment of the Figure 5 is intended to make it clear that instead of the flat inner conductor contact elements 10, inner conductor contact elements 10 with a round cross section can also be provided. The inner conductor contact elements 10 are designed as round, rigid contact pins. To form the contact sections 12, 13 spring tabs 14 are again provided, the contact pins being slotted at their ends in order to form four outwardly curved spring tabs 14 or spring tabs 14 with an outwardly protruding, spherical bead. Again, the spring tabs 14 are able to contact the contact sleeves 15 of the mating connectors 6, 7 from the inside. A latching connection 17 can also be provided. Figure 6 FIG. 3 shows one of the assembly connectors 5 of FIG Figure 5 in an enlarged side view.

Figure 7 shows a third exemplary embodiment of an assembly arrangement 1 according to the invention. The first assembly 2 and two of the first mating connectors 6 are shown in FIG Figure 7 hidden for better representation.

The embodiment of the Figure 7 shows a variant of the invention, according to which a multi-part inner conductor contact element 10 is provided which has an articulated connection 22 in a central region. Instead of the articulated connection 22, however, an elastic inner conductor contact element 10 can also be provided. In order to enable tilting and / or an axial offset, it is provided that the dielectric 11 has a funnel-shaped recess 23 that widens in the direction of the end in the region of one of its two ends. The contact connections are designed as an example as in the exemplary embodiment of FIG Figure 5 described.

Figure 8 shows a fourth exemplary embodiment of an assembly arrangement 1 according to the invention. The first assembly 2 and two of the first mating connectors 6 are shown in FIG Figure 8 hidden for better representation.

The embodiment of the Figure 8 is intended to make it clear that the contact sections 12, 13 of the inner conductor contact element 10 can each also be designed as a sleeve-shaped spring cage 24. Figure 9 shows a corresponding assembly connector 5 in an enlarged side view. The mating connectors 6, 7 have corresponding mating contacts 25 with spherical contact areas. The mating contacts 25 are designed in the manner of pin contacts. The mating contacts 25 are able to penetrate into the sleeve-shaped spring cage 24 of the inner conductor contact element 10 to form the lateral contact connection.
