DETAILED DESCRIPTION

(14) Before the coaxial connector according to the invention is discussed in detail, the coaxial connector according to the prior art will firstly be described below, in the non-plugged-together state on the basis of FIGS. 1A and 1B and in the plugged-together state on the basis of FIGS. 2A and 2B:

(15) The coaxial connector is composed of a first coaxial connector portion 1 and a second coaxial connector portion 2.

(16) The first coaxial connector portion 1 has a spring cage 3, which forms the external conductor, a substantially hollow cylindrical insulator part 4, which is situated within the spring cage 3, and a substantially cylindrical internal conductor 5, which is situated within the hollow cylindrical insulator part 4.

(17) The second coaxial connector 2 has a substantially hollow cylindrical external conductor 6, a substantially hollow cylindrical insulator part 7, which is situated within the external conductor 6, and a substantially cylindrical internal conductor 8, which is situated within the insulator part 7.

(18) In the three-dimensional side view as per FIGS. 1A and 1n the two-dimensional front view as per FIG. 1B, the spring cage 3 has substantially a prismatic hollow body with five edges. Thus, said spring cage 3 has a total of five spring lugs 9.sub.1, 9.sub.2, 9.sub.3, 9.sub.4 and 9.sub.5, which are separated from one another by in each case one gap 10.sub.1, 10.sub.2, 10.sub.3, 10.sub.4 and 10.sub.5. The invention however also encompasses a spring cage 3 having a different, technically expedient number of edges and therefore of spring lugs.

(19) Furthermore, each spring lug 9.sub.1, 9.sub.2, 9.sub.3, 9.sub.4 and 9.sub.5 has in each case one planar surface correspondingly to the prismatic main hollow body. The planar surface of each spring lug 9.sub.1, 9.sub.2, 9.sub.3, 9.sub.4 and 9.sub.5 narrows in each case with regard to its width toward the distal end of the first coaxial connector portion 1. Furthermore, in the direction of the distal end of the first coaxial connector portion 1, the planar surface of each spring lug is oriented radially inward in a first section and oriented radially outward in an adjoining second section. By means of the radial orientation of the second section of each spring lug 9.sub.1, 9.sub.2, 9.sub.3, 9.sub.4 and 9.sub.5, the second coaxial connector portion 2 can be more easily centered in the first coaxial connector portion 1 during the plugging-together process.

(20) In the plugged-together state of the coaxial connector as can be seen from FIGS. 2A and 2B, within the transition region between the radially inwardly directed first section and the radially outwardly directed second section of each spring lug 9.sub.1, 9.sub.2, 9.sub.3, 9.sub.4 and 9.sub.5, there is in each case substantially punctiform electrical contact with the external conductor 6 of the second coaxial connector 2.

(21) Each spring lug 9.sub.1, 9.sub.2, 9.sub.3, 9.sub.4 and 9.sub.5 has, on its inner side, in each case one elevation—a so-called bead—which is in each case not illustrated in FIGS. 1A, 1B, 2A and 2B and which runs centrally in the direction of the longitudinal axis of the coaxial connector.

(22) Proceeding from the distal end of the coaxial connector, said bead extends not over the full length of the spring lug 9.sub.1, 9.sub.2, 9.sub.3, 9.sub.4 and 9.sub.5. In that region of the respective spring lug 9.sub.1, 9.sub.2, 9.sub.3, 9.sub.4 and 9.sub.5 in which a bead runs, the respective spring lug 9.sub.1, 9.sub.2, 9.sub.3, 9.sub.4 and 9.sub.5 exhibits high stability in each case, whereas, in that region of the respective spring lug 9.sub.1, 9.sub.2, 9.sub.3, 9.sub.4 and 9.sub.5 in which the bead is omitted, the respective spring lug 9.sub.1, 9.sub.2, 9.sub.3, 9.sub.4 and 9.sub.5 exhibits high flexibility in each case.

(23) The comparison of FIGS. 1B and 2B shows that the gaps 10.sub.1, 10.sub.2, 10.sub.3, 10.sub.4 and 10.sub.5 between the individual spring lugs 9.sub.1, 9.sub.2, 9.sub.3, 9.sub.4 and 9.sub.5 are smaller in the non-plugged-together state of the coaxial plug connector than in the plugged-together state, and thus disadvantageously release a considerably greater amount of electromagnetic radiation and thus a considerably greater amount of electromagnetic signal energy from the coaxial connector.

(24) To reduce the radiation of electromagnetic signal energy through the gaps 10.sub.1, 10.sub.2, 10.sub.3, 10.sub.4 and 10.sub.5 between the individual spring lugs 9.sub.1, 9.sub.2, 9.sub.3, 9.sub.4 and 9.sub.5, shielding components 11.sub.1, 11.sub.2, 11.sub.3, 11.sub.4 and 11.sub.5 are respectively provided in the individual gaps 10.sub.1, 10.sub.2, 10.sub.3, 10.sub.4 and 10.sub.5.

(25) As known in the art, radiation of electromagnetic signal energy typically travels along straight line paths known as rays.

(26) As shown in the figures, spring lugs 9.sub.1, 9.sub.2, 9.sub.3, 9.sub.4, 9.sub.5 may constitute tab-like structures. As likewise shown in the figures, a tab may comprise at least one shielding portion in the form a respective shielding component 11.sub.1, 11.sub.2, 11.sub.3, 11.sub.4, 11.sub.5. As shown in the figures and described hereinbelow, the individual shielding components 11.sub.1, 11.sub.2, 11.sub.3, 11.sub.4, 11.sub.5 may be fastened to a respective tab, namely to a portion of the respective tab that may be designated as a first portion. As shown in the figures and described above, a tab may comprise at least one planar surface. As such, a tab may comprise, for example, a first plane 14.sub.1, 14.sub.2 defined by a major planar surface, e.g. by a major planar surface of the first portion of the respective tab. Similarly, a tab may comprise a second plane 16.sub.1, 16.sub.2 defined by a major planar surface, e.g. by a major planar surface of a second portion of the respective tab. A portion of the first/second portion toward the proximal end of the tab may be designated as a proximal portion. A portion of the first/second portion toward the distal end of the tab may be designated as a distal portion.

(27) As shown in the figures and described hereinbelow, a tab may comprise at least one bend. For example, in FIGS. 3A and 5A reference sign 22 identifies a bend along a border of a shielding portion. In the embodiments depicted in FIGS. 3A and 5A, bend 22 may furthermore be described as being intermediate the first portion and the shielding portion of the respective tab. In FIG. 4B reference sign 24 identifies another type of bend, namely a bend situated within the bounds of a shielding component. As depicted, such a bend may divide the shielding component into two regions. Bend 24 may furthermore be described as being intermediate a first region of the shielding portion and a second region of the shielding portion.

(28) In a first embodiment of the invention, in each case one shielding component 11.sub.1, 11.sub.2, 11.sub.3, 11.sub.4 and 11.sub.5 is provided in each gap 10.sub.1, 10.sub.2, 10.sub.3, 10.sub.4 and 10.sub.5. Said shielding component 11.sub.1, 11.sub.2, 11.sub.3, 11.sub.4 and 11.sub.5 is respectively fastened to a spring lug 9.sub.1, 9.sub.2, 9.sub.3, 9.sub.4 and 9.sub.5, preferably to the gap-side end of the spring lug 9.sub.1, 9.sub.2, 9.sub.3, 9.sub.4 and 9.sub.5, which is adjacent to the gap 10.sub.1, 10.sub.2, 10.sub.3, 10.sub.4 and 10.sub.5 that is to be shielded.

(29) In a first sub-variant of the first embodiment according to the invention as per FIGS. 3A and 3B, the shielding component 11.sub.1, 11.sub.2, 11.sub.3, 11.sub.4 and 11.sub.5 is preferably of planar design. It has a size, shape, position and orientation with respect to the respective spring lug 9.sub.1, 9.sub.2, 9.sub.3, 9.sub.4 and 9.sub.5 to which it is fastened which permit optimum shielding of the respective gap 10.sub.1, 10.sub.2, 10.sub.3, 10.sub.4 and 10.sub.5. The size, shape, position and orientation of the shielding component 11.sub.1, 11.sub.2, 11.sub.3, 11.sub.4 and 11.sub.5 also prevent jamming or blocking with the respectively oppositely situated spring lug 9.sub.1, 9.sub.2, 9.sub.3, 9.sub.4 and 9.sub.5 in the non-plugged-together state of the coaxial connector portion and during the plugging-together of the first coaxial connector portion 1 with the second coaxial connector portion 2.

(30) In a second sub-variant of the first embodiment according to the invention as per FIGS. 4A and 4B, the shielding component 11.sub.1, 11.sub.2, 11.sub.3, 11.sub.4 and 11.sub.5 has, approximately in the center of its width, in each case one bend which divides the individual shielding component 11.sub.1, 11.sub.2, 11.sub.3, 11.sub.4 and 11.sub.5 into two regions with respectively different orientation. The orientation of the two regions of each shielding component 11.sub.1, 11.sub.2, 11.sub.3, 11.sub.4 and 11.sub.5 corresponds approximately to the orientation of the respectively adjoining spring lug 9.sub.1, 9.sub.2, 9.sub.3, 9.sub.4 and 9.sub.5. Since the respectively adjacent spring lugs 9.sub.1, 9.sub.2, 9.sub.3, 9.sub.4 and 9.sub.5 have different orientations, a shielding component 11.sub.1, 11.sub.2, 11.sub.3, 11.sub.4 and 11.sub.5 with two regions whose orientation is approximated to the orientation of the adjoining spring lugs 9.sub.1, 9.sub.2, 9.sub.3, 9.sub.4 and 9.sub.5 realizes substantially optimum shielding of the interposed gap 10.sub.1, 10.sub.2, 10.sub.3, 10.sub.4 and 10.sub.5.

(31) In a third sub-variant of the embodiment according to the invention, the individual shielding components 11.sub.1, 11.sub.2, 11.sub.3, 11.sub.4, 11.sub.5 and 11.sub.6 as per FIG. 5A each have a curvature which corresponds to the curvature of the individual spring lugs 9.sub.1, 9.sub.2, 9.sub.3, 9.sub.4, 9.sub.5 and 9.sub.6.

(32) This third sub-variant of the first embodiment according to the invention is suitable in particular for a spring cage which has a hollow cylindrical main body. In the case of the third sub-variant of the first embodiment according to the invention, too, the gap is substantially optimally covered by the associated shielding component 11.sub.1, 11.sub.2, 11.sub.3, 11.sub.4, 11.sub.5 and 11.sub.6.

(33) In an enhancement of the first embodiment according to the invention, the individual shielding components 11.sub.1, 11.sub.2, 11.sub.3, 11.sub.4, 11.sub.5 and 11.sub.6 cover not only the respective gap but also a sub-region of the oppositely situated spring lug 9.sub.1, 9.sub.2, 9.sub.3, 9.sub.4, 9.sub.5 and 9.sub.6. This is illustrated in in FIG. 5B for the case of a curved shielding component 11.sub.1, 11.sub.2, 11.sub.3, 11.sub.4, 11.sub.5 and 11.sub.6 as per the third sub-variant of the first embodiment according to the invention. A shielding component 11.sub.1, 11.sub.2, 11.sub.3, 11.sub.4, 11.sub.5 and 11.sub.6 which covers not only the associated gap but also the oppositely situated spring lug 9.sub.1, 9.sub.2, 9.sub.3, 9.sub.4, 9.sub.5 and 9.sub.6 is also conceivable for the first and second sub-variants of the first embodiment according to the invention, and is also encompassed by the invention.

(34) In a second embodiment of the invention, in each case two shielding components 11.sub.1, 11.sub.2, 11.sub.3, 11.sub.4, 11.sub.5, 11.sub.1′, 11.sub.2′, 11.sub.3′, 11.sub.4′ and 11.sub.5′ are provided in each gap 10.sub.1, 10.sub.2, 10.sub.3, 10.sub.4 and 10.sub.5, which shielding components are respectively fastened to one of the two adjacent spring lugs 9.sub.1, 9.sub.2, 9.sub.3, 9.sub.4 and 9.sub.5. The two shielding components 11.sub.1, 11.sub.2, 11.sub.3, 11.sub.4, 11.sub.5, 11.sub.1′, 11.sub.2′, 11.sub.3′, 11.sub.4′ and 11.sub.5′ are in this case preferably fastened to the gap-side end of the respective spring lug 9.sub.1, 9.sub.2, 9.sub.3, 9.sub.4 and 9.sub.5. The doubling of the shielding components per gap improves the shielding of the respective gaps and thus reduces a radiation of the electromagnetic single energy out of the coaxial connector.

(35) In a first sub-variant of the second embodiment according to the invention as per FIGS. 6A and 6B, the two shielding components 11.sub.1, 11.sub.2, 11.sub.3, 11.sub.4, 11.sub.5, 11.sub.1′, 11.sub.2′, 11.sub.3′, 11.sub.4′ and 11.sub.5′ of a gap 10.sub.1, 10.sub.2, 10.sub.3, 10.sub.4 and 10.sub.5 are fastened in each case to the gap-side ends of the respectively adjacent spring lugs 9.sub.1, 9.sub.2, 9.sub.3, 9.sub.4 and 9.sub.5, and are directed radially outward with respect to the longitudinal axis of the coaxial connector. In this way, between the two shielding components 11.sub.1, 11.sub.2, 11.sub.3, 11.sub.4, 11.sub.5, 11.sub.1′, 11.sub.2′, 11.sub.3′, 11.sub.4′ and 11.sub.5′ of a gap 10.sub.1, 10.sub.2, 10.sub.3, 10.sub.4 and 10.sub.5, there is formed in each case one channel in which electromagnetic radiation energy is attenuated between the two oppositely situated shielding components 11.sub.1, 11.sub.2, 11.sub.3, 11.sub.4, 11.sub.5, 11.sub.1′, 11.sub.2′, 11.sub.3′, 11.sub.4′ and 11.sub.5′. The electromagnetic radiation energy is thus considerably attenuated at the exit of a channel of said type.

(36) In a second sub-variant of the second embodiment according to the invention as per FIGS. 7A and 7B, the two shielding components 11.sub.1, 11.sub.2, 11.sub.3, 11.sub.4, 11.sub.5, 11.sub.1′, 11.sub.2′, 11.sub.3′, 11.sub.4′ and 11.sub.5′ of a gap 10.sub.1, 10.sub.2, 10.sub.3, 10.sub.4 and 10.sub.5 at least partially cover one another.

(37) In a third sub-variant of the second embodiment according to the invention as per FIGS. 8A and 8B, the two shielding components 11.sub.1, 11.sub.2, 11.sub.3, 11.sub.4, 11.sub.5, 11.sub.1′, 11.sub.2′, 11.sub.3′, 11.sub.4′ and 11.sub.5′ of a gap 10.sub.1, 10.sub.2, 10.sub.3, 10.sub.4 and 10.sub.5 respectively cover a different section of the gap 10.sub.1, 10.sub.2, 10.sub.3, 10.sub.4 and 10.sub.5. The shape, size, the position and the orientation of the two shielding components 11.sub.1, 11.sub.2, 11.sub.3, 11.sub.4, 11.sub.5, 11.sub.1′, 11.sub.2′, 11.sub.3′, 11.sub.4′ and 11.sub.5′ of a gap 10.sub.1, 10.sub.2, 10.sub.3, 10.sub.4 and 10.sub.5 should in this case be configured such that, firstly, the respective gap 10.sub.1, 10.sub.2, 10.sub.3, 10.sub.4 and 10.sub.5 is as far as possible optimally covered by the two shielding components and thus shielded, and, secondly, no seizing, jamming or blocking of the two shielding components of a gap with respect to one another occurs in the plugged-together and non-plugged-together states of the coaxial connector and during the plugging-together of the first coaxial connector portion and of the second coaxial connector portion to form the coaxial connector.

(38) FIG. 9B shows a multiple coaxial connector portion in the non-plugged-together state, in which three first coaxial connectors 1.sub.1, 1.sub.2 and 1.sub.3 are arranged and integrated in parallel in one housing 12. The invention also encompasses the integration of a different number of first coaxial connector portions in one housing 12. FIG. 9A shows multiple coaxial connector portions plugged together in parallel, in the case of which the first coaxial connector portions 1.sub.1, 1.sub.2 and 1.sub.3 are each arranged and integrated in one housing 12 and the associated second coaxial connector portions 2.sub.1, 2.sub.2 and 2.sub.3 are each arranged and integrated in a further housing 13.

(39) The manufacturing method for producing a first coaxial connector having a prismatic basic structure will be described below on the basis of the flow diagram in FIG. 10:

(40) In the first method step S10, a planar component, which is intended to form the spring cage or the coaxial socket of the first coaxial connector portion, is punched in accordance with the axial length and the circumferential length of the spring cage or of the coaxial socket. For this purpose, a relatively large planar structural body composed of an electrically conductive material, preferably of a metal and particular preferably of a copper alloy, for example of spring bronze (CuSn.sub.6), is used. During the punching process, the shielding components that are provided in each gap of the spring cage are in particular also punched out in accordance with their size, their position and their shape.

(41) Here, it must be taken into consideration that the size, shape, number and arrangement of the individual shielding components in the individual gaps of the spring cage should be dimensioned and selected such that they can be punched out of the planar structural body in the region of the individual gaps of the spring cage that are formed.

(42) In the next method step S20, the punched-out planar component is bent to form a prismatic spring cage and is connected together at the two shell-side ends of the component of prismatic shape.

(43) In the subsequent method step S30, each shielding component in the individual gaps of the spring cage is bent and aligned with regard to its shape and its orientation with respect to the respective spring lug to which it is connected.

(44) In the next method step S40, into the spring cage produced in the preceding method step S30, which spring cage serves as external conductor, there are fitted the associated insulator part and the associated internal conductor are fitted, and said insulator part and internal conductor are connected to one another to form a first coaxial connector portion according to the invention.

(45) Optionally, in a final method step S50, multiple first coaxial connector portions produced in this way are fitted and fastened in a housing in order to produce a multiple coaxial connector portion.

(46) The spring cage with a prismatic and sleeve-shaped basic structure may also, alternatively to the punching and bending process, be produced by means of cutting manufacturing methods. The attachment of the shielding components to the individual spring lugs of the spring cage is also conceivable by means of mechanical connecting techniques, for example by means of brazing or welding.

(47) FIG. 11 finally illustrates a spectral illustration, created by means of simulation, of the shielding attenuation a.sub.D for the case of a spring cage without shielding component in the individual gaps (dashed line) according to prior art and for the case of a spring cage according to the invention with at least one shielding component in the individual gaps (solid line).

(48) It can be clearly seen that, over the entire frequency range considered, the shielding attenuation is much more pronounced in the case of a spring cage according to the invention with shielding components than in the case of a spring cage without shielding component according to the prior art.

(49) The invention is not restricted to the illustrated embodiments, sub-variants and enhancements. The invention also encompasses in particular all combinations of the features respectively claimed in the individual patent claims, of the features respectively disclosed in the description, and of the features respectively illustrated in the figures of the drawing, where technically expedient.
