Description

[0001] The invention relates to a connector, in particular a high-frequency connector, which has an outer conductor section with indentations. Furthermore, an assembly comprising the connector and a complementary connector is proposed. A method for manufacturing the connector is also described. Additionally, a method for manufacturing the assembly is described.

[0002] Conventional connectors feature a sleeve-shaped outer conductor section designed for electrical contact with the outer conductor of a coaxial cable. This outer conductor section is mated with a complementary outer conductor section of a complementary connector. In conventional connectors conforming to FAKRA standards, the outer conductor section has several spring-loaded tongues separated by slots. When the complementary outer conductor section of the complementary connector, which is often shaped like a hollow cylinder, is inserted, the spring-loaded tongues expand, enclosing and securing the complementary outer conductor section.

[0003] A disadvantage of such a design is that when lateral tension is applied to the outer conductor section, these spring tabs can widen or bend, impairing or losing the mechanical hold and contact between the two outer conductor sections. In the worst case, the connection – which can refer to the electrical and / or mechanical connection – between the outer conductor sections is severed by the mechanical force.

[0004] US 2021 / 119366 A1 discloses an electrical connector comprising an insulating housing with a base, a center conductor attached to the insulating housing, and a metal sleeve attached to the insulating housing and surrounding the center conductor. The metal sleeve includes a sleeve having a lower portion attached to the base of the insulating housing and an upper portion extending upward beyond the base of the insulating housing. The sleeve of the metal sleeve is designed as a seamless structure. An upper portion of the sleeve has a plurality of inwardly directed protrusions. The protrusions engage with a corresponding housing of a complementary electrical connector.

[0005] GB 2 307 358 A discloses a phono jack which is provided with a plurality of internal projections which, in conjunction with longitudinal slots, allow the jack to be used with plugs of different diameters.

[0006] EP 1 677 388 B1 discloses an electrical connector comprising an insulating housing with a base, a center conductor attached to the insulating housing, and a metal sheath attached to the insulating housing and surrounding the center conductor. The metal sheath comprises a sleeve having a lower part attached to the base of the insulating housing and an upper part extending upwards beyond the base of the insulating housing, the insulating housing being overmolded with the center conductor and the metal sheath; and the sleeve of the metal sheath being designed as a seamless structure.

[0007] The object of the invention is to provide a solution to the problem described above.

[0008] The problem is solved by a connector, an assembly, a method for manufacturing a connector, and a method for manufacturing an assembly according to the independent claims. Specific embodiments are given in the dependent claims, this description, and the examples.

[0009] According to the invention, a connector, in particular a high-frequency connector, is proposed. a housing made of electrically insulating material, an outer conductor part arranged inside the housing and designed in a section as a hollow cylinder or entirely as a hollow cylinder, an inner conductor part arranged at least partially inside the outer conductor part, an insulating part arranged at least partially inside the outer conductor part and at least partially enclosing the inner conductor part, wherein the outer conductor part inside the hollow cylinder has exactly two opposing backs, each of which has a plateau offset inwards with respect to an inner wall of the hollow cylinder, wherein the plateau of at least one of the backs has a section in the form of an outwardly bulging cylindrical shell segment or wherein the plateau of at least one of the backs has the form of an outwardly bulging cylindrical shell segment.

[0010] It has been shown that the connector according to the invention is particularly effective at absorbing transverse forces – such as those occurring during FAKRA oblique pull-off tests – and that bending of the outer conductors and / or damage to the contacts under forces encountered in practice, especially during installation and cable routing, can be avoided or largely prevented. This is achieved by oval-shaped deformations of the hollow cylinder and a complementary outer conductor section, offset from each other by 90 degrees or approximately 90 degrees when the connector according to the invention is considered in an assembly with the complementary connector. That is to say: The deformations of the complementary outer conductor section are offset by 90 degrees or approximately 90 degrees in the direction of rotation relative to the deformations of the hollow cylinder.These oval-shaped deformations are achieved because, according to an essential principle of the invention, exactly two plateaus (no more and no less) are provided so that, as a consequence, the advantages of the invention are achieved.

[0011] Features are sometimes described in the singular below, e.g., "the depression" or "the plateau." Such a description may also include, alternatively or additionally, a corresponding disclosure for several such features, if available.

[0012] The term "at least partially" is synonymous with "wholly or partially".

[0013] The transverse direction is the direction perpendicular to the central longitudinal axis (also called the central longitudinal axis) of the hollow cylinder. The central longitudinal axis of the hollow cylinder is the axis of symmetry of the hollow cylinder, i.e., the axis of symmetry of the rotationally symmetric cylinder, which is a section of the outer conductor part.

[0014] The backs are an integral part of the outer conductor section. The backs are positioned opposite each other with respect to the central longitudinal axis of the hollow cylinder. In other words, a first back is located on one side of the central longitudinal axis (laterally relative to the central longitudinal axis) and at a distance from the central longitudinal axis, and a second back is located on the opposite side of the central longitudinal axis, also at a distance from the central longitudinal axis. Exactly two backs are provided.

[0015] The backs are arranged inside the hollow cylinder, the hollow cylinder being a section of the outer conductor part or forming the outer conductor part itself. In other words, the backs are formed on or extend along the inside of the hollow cylinder. In other words, the backs are formed on or extend along the inner wall of the hollow cylinder. In other words, the backs are formed on or extend along the inner wall of the hollow cylinder. In other words, the backs are formed on or extend along the inner surface of the shell of the hollow cylinder. The backs are raised from the inner surface of the shell of the hollow cylinder. The backs rise inwards. The backs are raised from the inner wall of the hollow cylinder.

[0016] The ridges can run in or along the transverse direction. The ridges can extend longitudinally to form the plateaus. In particular, the ridges can extend more transversely than longitudinally. However, it is not impossible that the ridges extend more longitudinally than transversely.

[0017] The longitudinal direction is a direction parallel or aligned with the central longitudinal axis of the hollow cylinder.

[0018] The backs are preferably point-symmetric about a point on the central longitudinal axis of the hollow cylinder, or preferably mirror-symmetric about a mirror plane in which the central longitudinal axis lies.

[0019] The shortest distance between the backs is preferably the shortest distance between the plateaus.

[0020] The plateaus run inside the hollow cylinder.

[0021] The plateaus can also be described as (e.g., recessed or inwardly offset) surface sections or (e.g., recessed or inwardly offset) planar wall sections of the hollow cylinder. The plateaus can be formed, in particular, on the inner wall of the hollow cylinder. The plateaus can each connect the highest—that is, the innermost—points of the back. The highest points (i.e., those located furthest inward along a circumferential direction of the hollow cylinder) of the back are the highest points that result from cross-sections through the back. A cross-section through the back preferably lies parallel to the central longitudinal axis of the hollow cylinder in a plane whose normal direction is along the central longitudinal axis of the hollow cylinder, i.e., transverse or orthogonal to the central longitudinal axis. The above also applies accordingly to cross-sections through the hollow cylinder in general.Potentially infinitely many highest points can be defined.

[0022] In one embodiment, one or both plateaus extend in a planar direction when viewed transversely. However, odd shapes, e.g., curved shapes, are also possible, for example, along a virtual solid cylinder or a virtual solid cylinder shell whose central longitudinal axis may lie on the central longitudinal axis of the hollow cylinder. One or both plateaus can each correspond to surface sections of the virtual solid cylinder or the virtual solid cylinder shell. These surface sections can then have extensions in both the longitudinal and transverse directions. When referring to a virtual solid cylinder, a virtual solid cylinder shell may be meant.

[0023] One or both plateaus can each have a rotational extent of, for example, 10–120 degrees. Further lower limits can be 20, 30, 40, or 50 degrees. Further upper limits can be 100, 90, 80, or 70 degrees. Preferably, the rotational extent is between 30 and 90 degrees, more preferably between 40 and 80 degrees, or alternatively between 50 and 70 degrees, or alternatively between 55 and 65 degrees. A particularly preferred single value for the rotational extent is 60 degrees. A particularly preferred single value for the rotational extent for a single plateau is 60 degrees. The rotational extent can be understood as a quantity defined by an angle and / or the rotational extent of a plateau. For example, an extent of 60 degrees can be understood as an extent that covers one sixth of a total rotation of 360 degrees.

[0024] A ridge can be formed around the plateau—that is, along an outer contour of the plateau—for example, by rising continuously or sharply (e.g., step-like or edge-like). A ridge can be more or less sharply defined, or more or less step-like or continuously rising around the plateau. In particular, a ridge can include the plateau and its outer contour, or it can consist of the plateau and its outer contour.

[0025] The backs can be formed by reshaping the shell of the hollow cylinder. The shell can be reshaped where the backs are formed, thus deviating from its original cylindrical shape. In other words, the backs can be formed within the cylinder shell. For example, the backs can be formed by or created from indentations in the shell of the hollow cylinder. Alternatively, the backs can have formed surfaces or impressions in the shell of the hollow cylinder, or be formed by shaping or impressioning. The backs can be produced using a mandrel.

[0026] In one embodiment, the outer conductor part has two opposing recesses (or beads, formed surfaces, or impressed impressions) on the outer surface of a hollow cylinder's shell, through which the backs are formed or formed on the interior or inner wall. Viewed from the outside, there is thus a recess which, viewed from the inside, corresponds to a back. In this embodiment, the backs are formed by forming, as will be described below with reference to a method. However, the invention is not limited to this.

[0027] The indentations extend into the interior of the hollow cylinder.

[0028] The aforementioned depressions are preferably point-symmetric about a point on the central longitudinal axis of the hollow cylinder, or preferably mirror-symmetric about a mirror plane in which the central longitudinal axis lies.

[0029] Viewed from the outside, the depressions can form channels or grooves (each with an extension perpendicular to the direction of the respective groove) running transversely. The channels or grooves can, for example, taper to a point or curve in the transverse direction. Viewed from the outside, the depressions can also form or exhibit inwardly offset surfaces or impressions.

[0030] In one embodiment, the plateaus have a minimum distance of 90 to 98%, preferably 94 to 96%, particularly preferably 94.4 to 95.6% of the inner diameter of the hollow cylinder.

[0031] According to the invention, the plateau of at least one of the backs (or both backs) has, along its course (possibly each), a section in the form of an outwardly bulging cylindrical shell segment, or the plateau of at least one of the backs (or both backs) has (possibly each) the form of an outwardly bulging cylindrical shell segment. The outward direction is the direction extending from the central longitudinal axis of the hollow cylinder towards the shell of the hollow cylinder. In this embodiment, the cylindrical shell segment is visible when viewed along the central longitudinal axis of the hollow cylinder, with the bulge facing outwards, i.e., away from the central longitudinal axis. The cylindrical shell segment or both cylindrical shell segments can be part of a virtual solid cylinder or solid cylinder shell whose diameter is smaller than the diameter of the hollow cylinder.

[0032] In a more specific embodiment, the plateaus of both backs have, in their respective course, a section in the form of an outwardly bulging cylindrical shell segment, or the plateaus of both backs each have the form of an outwardly bulging cylindrical shell segment, wherein the cylindrical shell segments are each part of a virtual solid cylinder or solid cylinder shell. That is to say, the cylindrical shell segments can, in particular, each be part of the same virtual solid cylinder or solid cylinder shell.

[0033] In one embodiment, the virtual solid cylinder (or cylinder shell) lies concentrically within the hollow cylinder of the outer conductor section, with the central longitudinal axis of the virtual solid cylinder (or cylinder shell) lying in the central longitudinal axis of the hollow cylinder. A constantly wide (virtual) gap is thus formed between the virtual solid cylinder (or cylinder shell) and the inner wall of the hollow cylinder. This embodiment enables a particularly concentric insertion of a complementary outer conductor of a complementary connector, especially a cylindrical complementary outer conductor.

[0034] In one embodiment, the virtual solid cylinder (or solid cylinder shell) has a diameter which is 90 to 98%, preferably 94-96%, of the inner diameter of the hollow cylinder.

[0035] In a particular embodiment, the hollow cylinder does not have a longitudinally extending slot. In a more specific embodiment, the hollow cylinder, in particular, does not have spring tongues as known from the prior art.

[0036] This increases the strength and, in particular, the fatigue strength of the hollow cylinder and a plug connection with a complementary outer conductor part.

[0037] In one embodiment, the plateau of at least one of the backs has an extension along a transverse direction of the hollow cylinder and an extension along a longitudinal direction of the hollow cylinder, wherein the extension along the transverse direction is greater than the extension along the longitudinal direction.

[0038] The longitudinal direction can correspond to a central longitudinal direction of the hollow cylinder. The transverse direction can extend perpendicular to the central longitudinal direction. The plateau can, in particular, extend along the inner wall of the hollow cylinder in the direction of rotation and have a greater extent in the direction of rotation (along the transverse direction) than in the longitudinal direction. That is, the plateau can, in particular, extend in width along the direction of rotation or along the transverse direction in a shape similar to a strip, an oval, or an oval with tapered ends (similar, for example, to the externally visible contour of a human eye). The extent in the longitudinal direction can change along the transverse direction. Thus, the plateau can have a smaller longitudinal extent in the outer transverse areas and a greater longitudinal extent in the inner transverse areas.This embodiment is advantageous because it is easy to manufacture and offers particularly high stability under lateral forces.

[0039] In one embodiment, the plateau of at least one of the backs inside the hollow cylinder has a convex contour that extends at least partially in an arc shape along a transverse direction of the hollow cylinder.

[0040] The contour can be convex in such a way that a central part of the contour, or of a section of the contour, or of a flank of the contour – viewed in the transverse direction – is located closer to a plug-side end of the inner wall than parts of the contour spaced away from the central part. The contour can, in particular, be oval-shaped or oval-shaped with tapered end regions.

[0041] For example, if the contour has the shape of an oval or an oval with tapered ends (similar to the externally visible contour of a human eye), a long section of the oval or a section between the tapered ends may extend in the transverse direction and / or in the circumferential direction.

[0042] The contour can descend inwards from the inner wall of the hollow cylinder, particularly in the form of a continuous slope or a sloping incline.

[0043] The presented design offers the advantage of particularly simple assembly with a complementary outer conductor section and improved machine and / or automated processing. During insertion, the outermost edge of the complementary outer conductor section can first contact a central portion of the convex contour (viewed in the transverse direction) and then, only as the insertion process continues, come into contact with more distant parts of the contour. The insertion force required to insert the complementary outer conductor section can thus build up slowly and continuously.

[0044] In a further aspect, the invention relates to an assembly comprising the connector according to the invention and a complementary outer conductor part of a complementary connector, wherein the complementary outer conductor part has a complementary cylindrical section which is inserted at least partially into the hollow cylinder of the connector, wherein the complementary cylindrical section is in pressure contact with the plateaus and the complementary cylindrical section is compressed along an axis extending between the plateaus.

[0045] The hollow cylinder can additionally be widened along this axis. The axis can, in particular, be a transverse axis with respect to the connector according to the invention. The axis can be orthogonal to the central longitudinal axis of the hollow cylinder.

[0046] The complementary cylindrical section is deformed by pressure exerted on it by the hollow cylinder via the plateaus, causing its diameter between the plateaus to compress. If the diameter of the complementary cylindrical section is considered orthogonal to the axis between the plateaus (i.e., at a 90-degree angle to this axis), then it can (and usually will in practice) be expanded. The pressure causes a force from the hollow cylinder to act on the complementary section. This force can be a spring force or be understood as such.

[0047] The hollow cylinder, which has the backs with the plateaus, is expanded by (counter-)pressure exerted on the plateaus by the complementary cylindrical section. If the diameter of the hollow cylinder is considered orthogonal to the axis between the plateaus (i.e., at a 90-degree angle to this axis), then it can be (and usually is in practice) compressed.

[0048] The axis is to be understood as a virtual axis and can, for example, extend through the center of one plateau and the center of the other. The axis can intersect the central longitudinal axis of the hollow cylinder orthogonally. Compression along an axis can mean a decrease in the diameter of the complementary cylindrical section when its diameter is considered in the axial direction. Expansion along an axis can mean an increase in the diameter of the hollow cylinder when its diameter is considered in the axial direction.

[0049] The aforementioned compressions and expansions of both the hollow cylinder and the complementary cylindrical section result in a firm and stable connection between the hollow cylinder and the complementary connector. Due to the resulting self-centering and the forces that can act like a spring force, assembly is particularly simple and easily automated. Since neither the hollow cylinder nor the complementary connector contains any interruptions, such as slots or spring tongues, the assembly according to the invention is particularly effective at absorbing lateral forces. The advantages of the connector according to the invention apply accordingly.

[0050] The fact that the complementary outer conductor part is at least partially "inserted" into the hollow cylinder of the connector can, in particular, mean that the complementary outer conductor part is inserted into it and / or arranged in it and / or surrounded by it.

[0051] The assembly can alternatively or additionally comprise the connector according to the invention and a complementary outer conductor part of a complementary connector, wherein the complementary outer conductor part has a complementary cylindrical section which is inserted at least partially into the hollow cylinder of the connector. wherein the complementary cylindrical section is in pressure contact with the plateaus and the complementary cylindrical section is deformed in cross-section in the manner of a first oval, such that a narrow diameter of the first oval is located between the plateaus, wherein the hollow cylinder is deformed in cross-section in the manner of a second oval, such that a wide diameter of the second oval extends between the plateaus. The deformations need not correspond exactly to ovals. Oval-like deformations, for example, are sufficient, i.e., deformations that roughly correspond to ovals.

[0052] In another aspect, the invention relates to a method for manufacturing a connector according to the invention, or a component for such a connector, comprising Providing an outer conductor part which is formed in one section as a hollow cylinder, stamping two opposing depressions into the outer surface of the shell of the hollow cylinder, wherein exactly two ridges extending inside the hollow cylinder are formed, each having a plateau offset inwards with respect to an inner wall of the hollow cylinder, assembling the outer conductor part, the housing, the inner conductor part and the insulating part to form the connector or component.

[0053] Additional parts can be added during assembly to form the connector.

[0054] The process can refer to the assembly of a component that can be supplemented or assembled with other parts or components to form a connector.

[0055] The method can be used to manufacture any connectors according to the invention that have been structurally described above. Features of the embodiments or process features described above can also be incorporated into the method according to the invention. With regard to the method according to the invention, full reference is made to the embodiments of the connector according to the invention, and vice versa.

[0056] In a special variant, the process involves: the insertion or placement of a forming tool into the hollow cylinder and the shaping of one or both backs in such a way that the plateau of the respective back receives a section in the form of an outwardly bulging cylinder shell segment, or the plateau receives the form of an outwardly bulging cylinder shell segment.

[0057] In another aspect, the invention relates to a method for manufacturing an assembly according to the invention, comprising: Providing the connector according to the invention; providing a complementary connector with a complementary outer conductor part having a complementary cylindrical section; inserting the complementary cylindrical section at least partially into the hollow cylinder of the connector, wherein the complementary cylindrical section is placed in pressure contact with the plateaus and the complementary cylindrical section is compressed along an axis extending between the plateaus.

[0058] The hollow cylinder can also be widened along the axis.

[0059] The method can be used to produce any embodiment of the assembly according to the invention (in particular, any embodiment of the connector according to the invention that has been described structurally above). The previously described material features of the embodiments presented or the previously described process features of the method for manufacturing the connector can be the subject of the method according to the invention.

[0061] Identical reference symbols used in different drawings signify identical features, even if not every drawing refers to all features shown with reference symbols again.

[0062] Fig. 1 Figure 1 shows a connector 1 according to the invention, which in this case is an angled connector. However, the invention is not limited to angled connectors. The connector 1 has a housing 2 made of plastic. A base body 3, for example a zinc die-cast part, is rotatably mounted in the housing and is rotatable about the longitudinal axis L. A cable 4 runs transversely to the longitudinal axis L, i.e., at an angle, and is guided through sleeves 5, 6 and connected to the base body 3 by these sleeves.

[0063] Inside the housing 2 are an outer conductor part 7, an inner conductor part 8, and an insulating part 9. The inner conductor part 8, here a female inner conductor part, is electrically contacted with the inner conductor 11 of the cable 4 via the pin 10. The outer conductor part 7 is electrically contacted via the base body 3 and the conductive sleeves 6 and 5 with a shield 12, which is shown here in a stylized, fanned-out state.

[0064] Fig. 2 Figure 1 shows a connector 41 according to the invention, which in this case is not an angled connector but a straight connector. The invention is not limited to straight connectors. The connector 41 has a housing 42 made of plastic. A base body 43 is mounted in the housing. A cable 44 is guided through a sleeve 45.

[0065] Inside the housing 42 is an outer conductor part 47 and a female inner conductor part 48, which is electrically contacted with the inner conductor of the cable 4. The outer conductor part 47 is electrically contacted via the conductive sleeve 45 with a shield 52, which is shown here in a stylized, fanned-out state.

[0066] Fig. 3 shows section Y from Fig. 1 The ridges 13 and 14, indicated here with reference symbols, are formed by deformations in the outer conductor section 7. Indentations 15 and 16 are embossed on the outer surface of the outer conductor section 7, forming the aforementioned ridges 13 and 14 on the inner surface. The ridges 13 and 14 run along a transverse direction Q (and in the direction of rotation), which here runs in the direction of the viewer's gaze. The structure of the ridges and indentations is described in more detail with reference to the following figures.

[0067] First, in Fig. 4 An outer conductor section 7' ​​according to the prior art is shown. This outer conductor section 7' ​​has four spring tongues 17, which are separated from each other by slots 18 extending in the longitudinal direction L.

[0068] In contrast, in Fig. 5 an outer conductor part 7 is shown, as it is used in the connector 1 according to the invention and in Fig. 1 and 3as already shown. The outer conductor part 7 is designed as a hollow cylinder 19 in section A. In the longitudinal direction L, a flared part 20 adjoins it at the front, on the opening side. A complementary outer conductor 31 of a mating connector is inserted there (see Fig. 11 ).

[0069] In the other direction, 19 further, progressively narrowing sections 21, 22, 23 are attached to the hollow cylinder.

[0070] The hollow cylinder 19 has the shell 24, as well as the outer surface 25 and the interior (inner space) 26. The shell 24 has an inner wall 57.

[0071] The perspective view shows the recess 15, through which the back 13 (shown in Fig. 2 ) is formed, and the back 14, which is formed by the depression 16 (shown in Fig. 2 ) is formed. On the back 14 (as part of the back 14) a plateau 27 is provided, which extends over a larger area along the transverse direction Q (and in the direction of rotation). The plateau 27 also has a smaller extent in the longitudinal direction L, which varies along the transverse direction Q. The plateau 27 has an oval shape and contour with tapered end regions. The backs 13, 14 each have the plateau 27, 28 and the outer contour (more precisely: contour areas 27a, 27b, 28a, 28b, cf. Fig. 8 ) of the respective plateau 27, 28.

[0072] In this case, the transverse direction Q is exactly perpendicular to the longitudinal direction L, although perpendicularity is not mandatory according to the invention. Furthermore, the plateau 27, which in this embodiment extends symmetrically along the transverse direction Q, can also be odd or asymmetrical. A plateau 28 of the back 13 is shown with a reference numeral in parentheses because the plateau 28 runs inside 26, like the opposite plateau 27, and is not visible from the outside.

[0073] Fig. 6 shows a side view compared to the perspective view of the Fig. 5 The transverse direction Q is in the viewer's line of sight. The recesses 15, 16 each have a small, longitudinally extending, planar longitudinal section, which is surrounded on both sides by slopes.

[0074] Fig. 7 Figure 1 shows another view of the outer conductor part 7 according to the invention. The recess 15 can be seen in a top view – that is, the outer conductor part 7 is shown in the Fig. 7 opposite Fig. 6 rotated 90 degrees around the longitudinal direction L (which corresponds to the direction of the central longitudinal axis of the outer conductor part 7). The recess 15 (and also the recess 16, not shown) has, like the plateaus 27, 28, an oval-shaped outer contour with tapered end regions, wherein a strip-like surface area or imprint extending along the transverse direction Q is provided (e.g., pressed or embossed) in the center of the recess.

[0075] Fig. 8 This shows in Fig. 6-7 The outer conductor section 7 is shown in longitudinal section. The plateau 27 can be seen in plan view. Contour areas 27a and 27b extend continuously inwards from the inner wall 57 of the outer conductor section 7. This is also shown in

[0076] Fig. 9 evident, which the outer conductor part 7 in a opposite Fig. 8 The longitudinal section is shown rotated by 90 degrees. Contour areas 27a and 27b rise continuously towards the center of plateau 27. The same applies to plateau 28, which has contour areas 28a and 28b. Both plateaus are symmetrical with respect to the central longitudinal axis of the outer conductor section 7 (or a longitudinal plane that contains the central longitudinal axis and is orthogonal to an imaginary line connecting plateaus 27 and 28).

[0077] Figur 10 shows a cross-section along line CC from Fig. 6 The cut passes precisely through the deepest areas of depressions 15 and 16 and exactly in the middle of plateaus 27 and 28, which lie precisely in the cutting plane. This is particularly evident from the... Fig. 10 It is evident that the plateaus 27 and 28 each have the shape or profile of an outwardly bulging cylindrical shell segment. These cylindrical shell segments lie on the same virtual solid cylinder (or solid cylinder shell), not shown here, which is arranged concentrically and on the same central longitudinal axis as the hollow cylinder 19 and has a smaller diameter than the hollow cylinder 19 (and its inner wall 57). The cylindrical shell segments each have a radius of curvature that corresponds to the radius of curvature of the virtual solid cylinder (or solid cylinder shell).

[0078] The inner diameter of the hollow cylinder 19 is denoted by d1. The diameter of the virtual solid cylinder (or solid cylinder shell) is denoted by d2.

[0079] The cylinder shell segments can be obtained by inserting into the outer conductor part 7 of the Fig. 10 a cylindrical forming tool (not shown here) is inserted or placed centrally in the longitudinal direction L, which has the diameter d2 of the virtual solid cylinder (or solid cylinder shell).

[0080] Fig. 11 Figure 1 shows an assembly of the outer conductor part 7 and a complementary outer conductor part 31 of a complementary connector. Neither the connector 1 nor the complementary connector and their other components are shown here, but only the assembly of the outer conductor part 7 with the complementary outer conductor part 31. The complementary cylindrical section 32 of the complementary outer conductor part 31 is inserted into the outer conductor part 7 and into its hollow cylinder 19.

[0081] Fig. 12 and 13 each shows a section accordingly along line AA in Fig. 11 In Figur 12 It is evident that the outer diameter of the complementary cylindrical section 32 of the complementary outer conductor section 31 is larger than that in Fig. 7 The drawn diameter d2 of the virtual solid cylinder (or solid cylinder shell) is determined by shaping the cylindrical section 32, by shaping the backs 13, 14 and their plateaus 27, 28 and / or by shaping the cylinder 19. Fig. 13 The actual state shown is achieved in which the complementary cylindrical section 32 is inserted as far as possible into the hollow cylinder 19 and has a firm, planar pressure contact on its outside to the backs 13, 14, thereby creating a stable plug connection.

[0082] In one direction or axis R1 between plateaus 27, 28, the cylinder 19 is widened, and the complementary cylindrical section 32 is compressed in this direction. In a direction orthogonal to the direction between plateaus 27, 28 in the plane of the Fig. 13 In contrast, cylinder 19 is reduced in diameter (compressed), and the complementary cylindrical section 32 is widened. This results in oval-shaped deformations of both cylinder 19 and the complementary cylindrical section 32.
