Description

TECHNICAL FIELD

[0001] The invention relates to a hollow conductor assembly with a cavity for guiding high-frequency waves, wherein the hollow conductor assembly consists of one or more components which are put together to produce at least one wall section of the hollow conductor assembly which is loaded with high-frequency waves and which bounds the cavity, wherein at least one connecting element is provided which is designed and arranged to establish a high-frequency-compatible connection between the components or component sections which form the mentioned wall section. BACKGROUND

[0002] It is known from the prior art that hollow conductors consist of a plurality of assemblies. For example, split-block arrangements are known in which two metal halves are milled in the manner of half components and then assembled. This can also be considered with injection-molded and metallized plastic halves, and in the assembly a bonding process, a soldering process, a welding process, a screwing process and / or a riveting process is required in order to be able to achieve a connection which is as completely closed as possible and in particular mechanically gap-free.

[0003] In the connection according to the prior art, a mechanically gap-free connection should be pursued, because otherwise electromagnetic waves can exit from the gap, thereby limiting the functionality of the hollow conductor.

[0004] It is generally a disadvantage of the known processes for connecting assemblies of hollow conductors that they can limit the high-frequency-technical functionality of the hollow conductor. Thus, for example, soldering protrusions can undesirably protrude into the hollow conductor when soldering. Undesirable shrinkage cavities can also form and protrude into the hollow conductor when welding, where they undesirably interact with electromagnetic waves. The same problems arise with bonding and other processes in the prior art.

[0005] It is known that screws are provided for purely mechanical connections. In order to thereby produce a mechanically gap-free closure at all relevant points of the transition between the assemblies, on the one hand a large number of screws is often required. On the other hand it can happen that by warping when tightening one or more screws, such an undesirable mechanical gap is produced at points of the transition which are important in terms of high-frequency technology, since the screwed assemblies are then mechanically tensioned.

[0006] It is also known from the prior art that certain mechanical gaps are tolerated and a functional system is still established for a narrow bandwidth range by means of resonant shapes, such as electromagnetic bandgap structures (EBG). However, the functional system has a limited bandwidth, among other disadvantages, and in addition, for example, precise gap sizes can also be required, which is problematic in particular in mass production.

[0007] The mechanical clearances which can arise by the methods mentioned from the prior art limit the design freedom and reliability of such hollow conductors and also limit the functionality of such hollow conductors. SUMMARY

[0008] In the context of this, the object on which the invention is based is to improve the hollow conductors mentioned above in such a way that an improved connection between the two components of the hollow conductor is achieved, which can also be reliably used in series and mass production, in particular

[0009] The object is achieved by the subject-matter of independent claim 1. Advantageous embodiments of the invention are the subject-matter of the dependent claims.

[0010] It is proposed in this connection that the at least one connecting element completely or partially forms the mentioned wall of the hollow space of the hollow conductor component and / or is tangential to the mentioned wall of the hollow space of the hollow conductor component and / or completely or partially projects into the hollow space of the hollow conductor component and has or is formed by one or more protrusions which engage into at least one of the components or component sections which are joined together.

[0011] It is also included in the invention that the connecting mechanism is not formed in one piece with the first component, i.e. separately therefrom.

[0012] The high-frequency-compatible connection is preferably a connection which encloses the hollow space of the hollow conductor component for electromagnetic waves to be generated or present in such a way that the hollow space behaves as effectively as the hollow conductor, without necessarily being completely sealed here. Thus, after the joining together of the at least one or more components of the hollow conductor, the at least one connecting element can for example be completely or partially the contour of the inner wall of the hollow conductor and in cross-section a closed contour can be achieved. However, in the direction of propagation the contour does not necessarily have to be closed everywhere, so that in the region of the joining together of the components or component sections a kind of "garden fence" is derived which "closes" the contact area in the longitudinal direction.

[0013] In other words, it can be proposed that in the region of the contact points between one or more components of the hollow conductor component which are relevant for high-frequency technology a high-frequency-compatible connection is provided which makes the gap for the electromagnetic waves transmitted through the hollow conductor component disappear, even if a gap mechanically still exists or can exist. However, a gap-free implementation in the region of the connection is also included in the invention.

[0014] The hollow conductor component can for example be a hollow conductor, an antenna, a part of a hollow conductor or a part of an antenna. Thus, the term "hollow conductor component" also includes for example a hollow conductor or an antenna itself.

[0020] It is preferably proposed that one or more parts are connected to one another by another connection mechanism or not by another connection mechanism. It is thus conceivable that no other connection mechanism exists in addition to the connection mechanism according to claim 1.

[0021] However, a further connection mechanism is also provided, which is however arranged separately from the one or more parts. It is understood that, in said embodiment, the further connection mechanism is arranged in such a way that it is not an integral part of the conduction path of the high-frequency waves and has no influence on said high-frequency waves.

[0083] Furthermore, the present invention relates to a high-frequency technology system having at least one hollow conductor assembly according to any one of the preceding claims. Here, it may be one or more circuit boards, antennas, or antenna arrays, or a portion thereof.

[0084] The present invention also relates to a method for manufacturing a hollow conductor according to the present invention and / or a high-frequency technology system according to the present invention.

[0085] It should be noted here that the terms "a" and "an" do not necessarily refer to exactly one element among the elements, although this is a feasible implementation, but can also represent multiple elements. Similarly, the use of the plural includes the presence of elements in the singular, and conversely, the singular also includes multiple elements among the elements in the plural. Furthermore, all features of the invention described herein can be claimed arbitrarily in combination with each other or independently of each other.

[0086] Other advantages, features and effects of the present invention will become apparent from the following description of preferred embodiments and from the accompanying drawings, which illustrate preferred embodiments of the invention.

[0087] The first embodiment relates to a hollow conductor in an antenna array for radar used in the automotive field.

[0088] First, a flat sheet metal is formed with multiple U-shaped grooves in its cross-section using a pressing or deep drawing method, with one side of the grooves open. Additionally, other recesses or openings are introduced along the grooves for subsequent joining.

[0089] In another sheet metal section—for example, by means of stamping—radiating, slit-like openings are introduced, which should form the radiating slits of the antenna. Furthermore, tabs are introduced into the second sheet metal section by introducing U-shaped cutting lines. The tabs are bent and act as cutting edges for connecting elements / connecting mechanisms.

[0090] Two sheet metal pieces are joined together, for example by pressing, such that a groove in the first sheet metal, together with the second sheet metal, forms a cavity. Here, the radial slot in the second sheet metal is located in an area that, together with the slot in the first sheet metal for this purpose, constitutes a hollow conductor slot antenna. The area of ​​the hollow conductor supplying power to the antenna and the distribution network formed therefrom does not necessarily have the slot in the second sheet metal.

[0091] The connecting element is introduced into a recess or opening provided in the first sheet metal along the groove during assembly. Therefore, the connecting element closes the cross-section of the hollow conductor at its location and ensures—from a high-frequency technology perspective—a connection suitable for HF. Furthermore, the connection may have gaps or holes, particularly in the contact area along the hollow conductor profile. However, these gaps or holes no longer impair HF functionality.

[0092] The contact area established by means of the blade can also retain mechanical clearance between components in the region of the hollow conductor cross-section, thereby enabling coarser production tolerances, which is particularly advantageous for batch or mass production.

[0093] One component of the assembly can be entirely or partially additively manufactured due to its geometric complexity. For example, by means of plastic-3D printing and subsequent metal cladding. In particular, hollow conductors, hollow conductor assemblies, and / or antennas may already exist before being assembled together. Detailed Implementation

Through the shown shaping of the protrusion, a [shape / form] is achieved on the upper side of the cover member 10. Figure 1 The recess is visible in the middle. A protrusion is created by introducing the tab into the cover component via a U-shaped cutting line. The tab created here is bent and is a blade, that is, a protrusion that serves as a connecting element / connecting mechanism.

[0105] According to the embodiment, the aforementioned connection mechanisms 30 and 40 of the hollow conductor establish a high-frequency applicable connection between component 10 and component 20, and interact with electromagnetic waves guided in the hollow conductor.

[0106] In the embodiment shown here, the connecting mechanism is an integral part of the cover component 10 and the lower component 20.
