Description
Technical Field
The invention relates to a high-frequency plug-in connection device for detachably contacting a coaxial contact partner, in particular a BMA plug, according to the preamble of claim 1. The invention further relates to a plug connection system according to claim 11, having a high-frequency plug device and a contact partner, in particular a BMA plug.
Background
In the contacting of high-frequency plugs (HF plugs), various requirements have to be met in order to transmit the corresponding high-frequency signals.
On the one hand, due to the so-called Skin effect (Skin-effect), it is important to ensure that the coaxially guided outer conductor of such an HF plug is in contact on its inner side. At the same time, in order to avoid undesired resonances, for example in the form of resonance chambers, it is desirable or desirable to tap the signal as far as possible over the entire circumference of the inner surface of the outer conductor of the HF plug. If possible, the fact that the contacts to the plug device are to be formed or formed over the entire inner circumference of the outer conductor leads to the need to generate corresponding requirements on a high-frequency plug device (HF plug device) which interacts with such an HF plug, in particular a coaxial HF plug, in order to generate the contacts and transmit signals.
Further special requirements of high-frequency plug-in devices for detachably contacting coaxial contact partners (in particular HF plugs) are: a very small radial spacing between the outer conductor and the inner conductor, wherein, according to the above-mentioned problems, this small free space has to be used or utilized for inserting or at least partially introducing the inner conductor assembly and the outer conductor assembly into a coaxial HF plug (preferably a BMA plug), so that in the introduced state both a contact of the inner conductor on the outer surface with the inner contact portion of the inner conductor assembly and a contact of the outer conductor on the inner surface with the outer contact portion of the outer conductor assembly are produced.
In this type of plug-in device, there are also problems: the inner contact of the outer conductor of the plug-in counterpart is released by means of a deformable sliding contact (lamellar contact). But these are disadvantageous for different reasons. The disadvantage of the laminar sliding contacts is the very limited service life, so that a very limited maximum number of connections can be made efficiently and reliably by such high-frequency plug devices before the plug devices have to be repaired or even replaced immediately due to wear or damage to the outer contact portions of the outer conductor assemblies which are designed as laminar. Furthermore, with the known laminar sliding contacts as the outer contact section of the outer conductor assembly for the outer conductor of the inner contact counterpart, the necessary or required adaptation of the resulting total impedance can only be achieved to a very limited extent, which in turn is of great importance for minimizing signal reflections.
Disclosure of Invention
Against this background, it is an object of the present invention to provide a high-frequency plug device for detachably contacting a coaxial contact partner, in particular a BMA plug, and a plug connection system having a high-frequency plug device and a contact partner, in particular a BMA plug, in which an outer conductor arrangement is realized which is in reliable, permanent contact with the entire inner circumference of the outer conductor of the contact partner.
This object is achieved by a high-frequency plug-in device according to claim 1. The object is likewise achieved by a plug connection system having the features of claim 11. In particular, high-frequency plug devices for detachably contacting coaxial contact partners (in particular BMA plugs) generally have: an outer conductor arrangement forming an end-side outer contact section and an inner conductor arrangement forming an end-side inner contact section, wherein the outer conductor arrangement and the inner conductor arrangement are preferably jointly movable in the axial direction relative to the guide sleeve and are preferably shiftable from a rest position into a contact position and back into the rest position under elastic deformation of the spring element, are provided according to the invention in such a way that: the outer conductor arrangement comprises an expansion body arranged at the end, which is designed to: upon reaching the contact position, the force acting on the expansion body by the contact counterpart (in particular by the outer conductor of the contact counterpart) causes a radial deformation of the expansion body in the axial direction, which presses the outer contact section (preferably arranged on the expansion body) from the radially inner side towards the outer conductor of the contact counterpart.
By means of the solution according to the invention, surprisingly and contrary to the known laminar contacts for contacting the outer conductor, a radial relative movement of the outer contact part can be achieved, which is produced in a particularly advantageous manner by the necessary axial adjustment and the resulting contact between the plug device and the contact partner, so that a reliable or at least almost continuous contact with the inner surface or inner circumference of the outer conductor of the contact partner and thus a continuous or at least almost continuous contact with the inner surface over the entire outer circumference is achieved. The reversibly deformable expansion body has a durability which is increased by several times and a wear rate which is degraded by several orders of magnitude, so that a significantly greater number of reliable and high-quality contacts with the outer contact section according to the invention can be realized for signal transmission. In addition, it is also achieved in a particularly advantageous manner that: the outer contact section of the expansion body of the outer conductor arrangement predominantly establishes or forms a mechanical contact with the outer conductor only when the plug device reaches the contact position, so that, at best, no or only minimal axial displacement takes place in the contact range between the outer conductor of the contact partner and the outer contact section of the outer conductor arrangement of the plug device, thereby ensuring that the outer contact section and the inner surface of the outer conductor of the contact partner are not damaged or abraded by mechanical damage, scratching or abrasion.
In addition to the use in the field of coaxial plugs, the subject matter of the invention also relates to, for example, spring-loaded contact pins having the inventive expansion body arranged in a contact region or contact section. The invention can therefore be extended from the outer conductor arrangement to a generic contact device or contact pin using an expansion body, wherein the expansion body makes contact on the inner surface of a generic contact partner (for example in the form of a bushing or hollow body).
According to a first advantageous embodiment of the plug device, it is provided that the expansion body has a radially outwardly projecting support edge spaced apart from the outer contact section, which support edge is preferably circumferential in the circumferential direction and which is provided to bear on a front end or front edge of the outer conductor of the contact partner when the contact position is reached or is about to be reached. The spacing between the support edge and the outer contact section is particularly preferred for lever arm formation or torque formation. The radial projection of the support edge essentially provides for supporting it at its end side on the end or edge of the outer conductor of the contact partner. In order to ensure as uniform an expansion of the expansion body as possible and a resulting radial expansion of the outer contact section when the contact position of the plug-in device is reached, it is particularly advantageous if the support edge is formed completely in the circumferential direction. It may however also be provided that the support edge is formed only in certain areas or parts of the outer periphery.
In a further particularly preferred embodiment of the plug device, it can be provided that the expansion body comprises a region of reduced wall thickness on the side of the support edge remote from the outer contact section. The reduced wall thickness on the side of the support edge remote from the outer contact portion enables better or easier deformability in the radial direction, in particular expansion of the expansion body. The elastic deformation of the expansion body is carried out in an area arranged on the side of the support edge remote from the outer contact portion. In other words, the expansion characteristics can be adjusted or determined by adjusting the wall thickness of the originally axisymmetric expansion body. In order to achieve a sufficient radial expansion of the expansion body in the event of a predetermined or predefined pressing force of the plug device on the contact partner in the axial direction, it is necessary for the outer contact part to be in contact with the inner surface of the outer conductor of the contact partner.
Alternatively or in addition, provision may be made for the expansion body to have a plurality of, preferably 2 to 12, slots distributed over the circumference, which are preferably distributed uniformly over the circumference and extend in the axial direction from the end of the expansion body corresponding to the outer contact section at least as far as the height of the support edge, preferably as far as the region of the expansion body in which the wall thickness is reduced. The desired state can be deviated by a predetermined slot, wherein the desired state is set as: the outer conductor of the contact partner is contacted over the entire circumference (in particular the inner surface of the outer conductor of the contact partner), but the slot in the expansion body can be designed as a filament, so that the risk of forming a resonance chamber with a corresponding contact of the outer conductor with the outer contact portion of the expansion body is small and negligible. The particular advantage of providing corresponding axially extending slots on the outer circumference of the expansion body is also: the expansion of the expansion body is better controllable, durable and reversible.
In a further advantageous embodiment of the plug device, the outer contact section has a curved outer surface which projects radially outward and which is preferably parabolic or circular-arc-shaped and in particular has such dimensions that the maximum outer diameter of the outer contact section in the unstressed or undeformed state is slightly smaller than the inner diameter of the outer conductor of the contact partner. A better and reliable contact can be achieved by the outer surface of the outer contact section of such a curved, preferably parabolic or circular-arc-shaped expansion body, even when the plug device in the contact position is not arranged completely parallel to the contact partner but is slightly deflected relative thereto. By designing the maximum outer diameter of the outer contact section in the undeformed or unexpanded state of the expansion body preferably slightly smaller than the inner diameter of the outer conductor of the contact partner, in the ideal case, the contact of the inner surface of the outer conductor of the contact partner is achieved by radial expansion of the expansion body only immediately before the contact position is reached or reached, and mechanical contact, in particular wear, friction or scraping, between the outer contact section and the outer conductor (or even between the outer conductor assembly and the outer conductor) is not caused during the transition of the plug-in device between the contact position and the rest position. In a particularly advantageous embodiment of the plug-in device, it is furthermore provided that the outer contact section is arranged at the front end of the expansion body. The front end of the expansion body is preferably opposite the end of the expansion body corresponding to the support edge.
In accordance with a further particularly preferred embodiment of the plug device, it is also provided that the support edge has, on the side facing away from the outer contact section, a radially inwardly extending bevel oriented away from the outer contact section, which bevel preferably merges via a protruding bend into the housing section of the expansion body. This wing-or mushroom-shaped design of the support edge has different advantages. On the one hand, even if the support edge is not aligned completely parallel to the front edge of the outer conductor of the contact partner, an effective and sufficient expansion of the expansion body is still allowed, which may be due to different reasons, at least to a tilting of the contact partner or to an unevenness of the front edge of the outer conductor. In addition, such a shape allows setting and determining the required and preset torque in a desired manner.
In accordance with a likewise preferred embodiment of the plug device, it is provided that the support edge has, on the side facing away from the outer contact section, a radially inwardly extending bevel oriented away from the outer contact section, which bevel preferably merges or merges into a region of reduced wall thickness of the expansion body. By means of such a design of the outer contour of the support edge (i.e. the outer contour of the support edge remote from the outer contact portion) it is possible on the one hand to ensure that the forces to be absorbed, i.e. the forces occurring when contacting the front-side end or the front-side edge of the outer conductor, are absorbed or conducted and at the same time to ensure that a reversible and moderate deformation of the expansion body, i.e. an expansion of the expansion body in the radial direction, is caused.
In a further particularly preferred embodiment, the axial extent of the inner conductor arrangement, in particular of the inner contact section, is likewise dimensioned such that, when the contact position is reached, the axial boundary of the inner conductor or of the inner contact section defined by the contact partner is spaced apart from the axial end of the inner contact section of the inner conductor arrangement. Such a dimensioning of the inner conductor assembly with the inner contact portion relative to the outer conductor assembly with the outer contact portion reliably achieves a contacting of the inner conductor and in each case an expansion of the support edge or a comparable device causing an expansion of the expansion body when the contact position is reached, which can be manipulated or activated by an axial force so that the inner contact portion strikes against the axial boundary of the inner conductor before the inner contact portion of the inner conductor assembly limits or terminates the axial adjustment of the adjusting means.
It is also advantageously provided that, with respect to the spring element which has a restoring effect on the displacement of the plug device relative to the guide sleeve and with respect to the contact partner, the expansion body is dimensioned such that: when a predetermined axial target contact pressure of the plug device on the contact partner is reached, a radial deformation of the expansion body is caused, which brings about a contact between the outer contact part and the outer conductor. In other words, when the contact position is reached, the spring element forms a sufficient resistance or a sufficient reaction force, so that a necessary and large axial force is generated between the expansion body (preferably the supporting edge of the expansion body) and the contact partner (preferably the outer conductor of the contact partner), which then translates into a radial expansion of the expansion body.
It is also particularly advantageously provided that a guide and/or protective sleeve is provided at the end of the plug device, on which the inner contact part and the outer contact part are formed, which guide and/or protective sleeve can serve on the one hand as a guide when approaching the contact partner and on the other hand as a protection against damage to the inner conductor arrangement and the outer conductor arrangement. The guiding and/or protecting sleeve may preferably be made of plastic.
The invention also solves the problem with a plug connection system for a high-frequency plug, with a high-frequency plug device according to one of the embodiments described above and a high-frequency contact partner (in particular a BMA plug).

Detailed Description
Fig. 1 shows a plug device 01 having an outer conductor arrangement 02 and an inner conductor arrangement 03. The outer conductor arrangement 02 and the inner conductor arrangement 03 are displaced in the axial direction a relative to the guide sleeve 04, wherein the displacement of the outer conductor arrangement 02 and the inner conductor arrangement 03 relative to the sleeve 04 deforms the spring element 05 and generates a restoring force. The illustration of fig. 1 shows the outer conductor assembly 02 and the inner conductor assembly 03 in a rest position with respect to the guide sleeve 04. In this rest position, the stop 06 placed in the guide sleeve 04 is forced by the spring element 05 toward the tapered end 07 of the guide sleeve 04. The guide sleeve 04 is connected to the mounting 08 for connecting the plug device 01 to a further counterpart, for example a circuit board or the like. On the rear side of the plug device 01, a contact interface 09 is provided, via which electrical signals detected and forwarded by the outer conductor arrangement 02 and the inner conductor arrangement 03 can be decoupled, transmitted or forwarded.
In a variant of the embodiment shown in fig. 1, the inner conductor arrangement 03 can also be designed as a separate spring contact pin or as a separate spring-acting inner conductor arrangement which, in addition to being placed in the guide sleeve 04, can be moved, preferably mounted in a spring-loaded manner relative to the outer conductor arrangement. Such separately mounted inner conductor assemblies are known in the art in different forms. Here, the matching is performed according to the characteristics and shape of the main body of the inner conductor of the contact mating member.
At the radially outer, opposite end of the outer conductor assembly 02, there is a protective and guide sleeve 10, which simplifies the contacting of a contact partner, which is not shown in fig. 1. As can already be seen in fig. 1, the outer conductor arrangement 02 has an expansion body 11 arranged at the end, which expansion body 11 is designed as: upon reaching the contact position, the axial force exerted by the contact partner on the expansion body 11 is converted into a radial deformation of the expansion body, so that the outer contact section 12 of the expansion body 11 is pressed from the radially inner side against the outer conductor of the contact partner. The specific function and interaction of expansion body 11 is described in more detail with reference to figures 2 to 4 below.
However, it can also be seen in fig. 1 that the expansion body 11 has a radially outwardly projecting support edge 13 spaced apart from the outer contact portion 12, which support edge 13 is provided for: a support formed on the front-side end of the outer conductor of the contact fitting upon reaching the contact position or immediately upon reaching the contact position. It can also be seen from fig. 1 that the expansion body 11 has a region 14 of reduced wall thickness in a region remote from the supporting edge 13 of the outer contact section 12. It is likewise possible to see from fig. 1 a slot 15 which extends in the axial direction a from the end of the expansion body 11 corresponding to the outer contact section 12 up to the region 14 of reduced wall thickness. The areas of reduced wall thickness 14 and the slots 15 are used for: the force acting in the axial direction from below on the support edge 13 is converted into a torque, so that at least the outer contact section 12 is thereby also moved or spread radially outward.
Fig. 2 shows a plug-in device 01 substantially according to fig. 1 and an associated contact partner 16 in the form of a BMA plug. The contact partner 16 has an inner conductor 18 in addition to an outer conductor 17. In order to transmit electrical signals between the contact fitting 16 and the plug device 01, as good a contact as possible must be made between the inner conductor arrangement 03 and the inner conductor 18 and between the outer conductor 17 and the outer conductor arrangement 02 (in particular the outer contact section 12 of the outer conductor arrangement 02).
For the connection between the inner conductor arrangement 03 and the inner conductor 18, this contact is effected in a manner known per se by means of an inner contact section 19, which inner contact section 19 is designed essentially as a slotted sleeve and is slipped onto the inner conductor 18. The contact of the outer conductor 17, which is preferably carried out on the inner surface 20 of the outer conductor 17, is effected by the expansion body 11 according to the invention and the outer contact part 12 provided at its end side in such a way that, upon reaching the contact position of the plug device 01 (see fig. 3), the support edge 13 of the expansion body 11 is supported on the front end 21 of the outer conductor 17 and the force thus generated in the axial direction a and acting on the support edge 13 is converted on the support edge into an expansion of the expansion body 11, which in turn ensures that the outer contact part 12 is pressed or pressed from the radial inside toward the outer conductor 17 of the contact partner 16. As can be gathered from the illustration in fig. 2, the outer diameter of the outer contact section 12 is equal to or slightly greater than the inner diameter of the outer conductor 17, and the dimensional ratio, in particular the diameter ratio, shown in fig. 2 between the inner surface 20 of the outer conductor 17 and the outer diameter of the outer contact section 12 represents a possible embodiment of the expansion body 11. In this embodiment, when the contact position is reached, the contact between the outer contact part 12 and the inner surface of the outer conductor 17 is already formed partially or circumferentially in the circumferential direction before the expansion body 11 is expanded. This may lead to undesired wear or friction in the outer contact part 12 and in the contact partner, in particular the outer conductor 17. Accordingly, in a particularly advantageous embodiment it is provided that the radially projecting outer contact section 12, preferably the parabolic or circular-arc-shaped outer surface, is dimensioned: in the rest position or in the unexpanded position of the expansion body 11, the maximum outer diameter of the outer contact section 12 is slightly smaller than the inner diameter of the outer conductor 17 of the contact partner 16.
In the latter case, rubbing or scraping of the outer side contact part 12 on the inner surface 20 of the outer side conductor 17 is completely avoided and only a radially outwardly oriented pressing force of the outer side contact part 12 is exerted on the inner surface 20 of the outer side conductor 17 when the contact position is reached. As can be seen from fig. 2, the protective and guide sleeve 10 serves to align the plug device 01 relative to the contact fitting 16.
Fig. 3 also shows a system comprising a plug device 01 and a contact fitting 16. In this case, the plug device 01 (in particular the outer conductor arrangement 02) is transferred together with the inner conductor arrangement 03 into the contact position, which is made clear by the movement of the stop 06 in the sleeve 04. For the sake of clarity, the spring element 05 is not shown in the illustration of fig. 3 but is shown in fig. 1.
It can also be seen in fig. 3 that the support edge 13 is already supported on the front end 21 of the outer conductor 17 and that the force acting on the contact fitting 16 in the axial direction a by the plug device 01 results, in addition to the deformation of the spring element 05, in: said front edge 21 of the outer conductor 17 exerts a force acting in the axial direction a on the support edge 13, which force further provides a lever arm or generates a torque, so that the outer contact portion 12 is pressed from the inside towards the outer conductor 17. In this case, the support edge 13 has a shape that will be explained in more detail below with reference to fig. 4.
Fig. 4 shows an enlarged view of the expansion body 11, which expansion body 11 has a supporting edge 13 at approximately half the height in the axial direction a. Also visible in the figure is a curved (preferably parabolic or circular arc-shaped) outer contact portion 12 which projects radially outwards. The support edge 13 has, on a side 22 facing the outer contact portion 12, a radially inwardly extending bevel 23 oriented away from the outer contact portion 12, which bevel 23 transitions via a bend 24 into a jacket portion 25 of the expansion body 11. By means of this design, a contact between the supporting edge 13 and the outer conductor 17 which extends as far as possible over the entire circumference can be achieved when the contact position 16 is reached, even if the plug device 01 is slightly inclined relative to the axis of symmetry or coaxial axis of the contact counterpart 16. On the side 26 of the support edge 13 facing away from the outer contact part 12, a radially inwardly extending bevel 23 facing away from the outer contact part 12 is provided, which bevel 23 merges into the region 14 of reduced wall thickness of the expansion body 11. In this case, the slot 15 extends from the end corresponding to the outer contact portion 12 via the support edge 13 up to the region 14 of reduced wall thickness.
