Description

FIELD OF THE INVENTION

The present invention relates to an electrical contact device, a first elastic element included in this electrical contact device, and an assembly containing this electrical contact device.

TECHNICAL BACKGROUND

As a fast data transmission interface for high-frequency signals between two high-frequency components, such as two printed circuit boards, each with a high-frequency electronics, so-called board-to-board connectors have established (German: PCB to PCB connector). These board-to-board connectors not only have the task of providing an electrical connection for high-frequency signals between the two high-frequency components with matched characteristic impedance, but also to compensate for an axial offset and an angular offset between the two high-frequency components.

In particular, to compensate for the axial offset between the two high-frequency components so-called coax SLC contact elements (English: coaxial spring loaded contact, German: coaxial springing contact) is used. For example, in the US 7,416,418 B2 the structure and operation of such a Coax SLC contact element is disclosed:

The inner conductor side contact is known as a spring contact pin, i. as a contact pin, which is resiliently mounted in a bush-shaped housing, realized. While the sleeve-shaped housing is typically fixed to the one high-frequency component, the contact pin contacts with its contact tip the respective other high-frequency component. The outer conductor side contact is realized as a contact ring, which is resiliently mounted to a slotted contact socket. The slotted contact socket is typically fixed to the one high-frequency component, while the contact ring contacts the respective other high-frequency component

Due to the suspension of the contact pin in the bush-shaped housing, a sufficient contact pressure and thus a secure electrical contact between the contact tip of the contact pin and an associated contact surface on the respective other high-frequency component within a certain range for the distance between the two high-frequency components can be realized inside conductor side. Equivalent is the outside conductor side by the suspension of the contact ring also a sufficient contact pressure and thus a secure electrical contact between the contact ring and an associated contact surface on the respective other high-frequency component within a certain range for the distance between the two high-frequency components feasible.

As the representations in the US 7,416,418 B2 As can be seen, a Coax SLC contact element contains a comparatively large number of individual parts, which unnecessarily increases the costs for the production and logistics of such a product. In addition, the geometric extent of such a Coax SLC contact element is still too large to meet future requirements for the distance between a plurality of coax SLC contact elements positioned in a grid or in a row.

This is a condition to be improved.

The underlying idea / idea of the present invention consists in realizing the two technical functions of electrical insulation (insulator element) originally realized in two separate components and the application of an axial elasticity (spring) in a single component. For this purpose, according to the invention, between the at least one inner conductor and the outer conductor, an elastic element, which is referred to below as the first elastic element, made of an electrically insulating material. Due to its arrangement between the at least one inner conductor and the outer conductor and its electrically insulating property, the first elastic element serves on the one hand as an insulator element within the high-frequency contact device.

Due to its elasticity and its fixation on the outer conductor, the elastic element in the compressed case - if the variable in its axial extent outer conductor is also compressed when contacting the first and the second component - transmitted to the outer conductor a spring force, with the outer conductor one sufficient contact pressure on the first and second component exerts.

In this way, a compact electrical contact device for high-frequency signals from a minimized number of individual parts is provided according to the invention, which realizes reliable electrical contact between the two high-frequency components depending on the present in each moment axial offset between the two high-frequency components to be connected.

The outer conductor and the at least one inner conductor can each be firmly connected to the first component and / or to the second component, for example by means of a solder connection.

Alternatively, the outer conductor and the at least one inner conductor can each contact the first component and / or the second component only electrically. In this case, the outer conductor and the at least one inner conductor are each pressed against associated contact surfaces on the first component and / or on the second component.

Advantageous embodiments and further developments will become apparent from the other dependent claims and from the description with reference to the figures of the drawing.

It is understood that the features mentioned above and those yet to be explained below can be used not only in the particular combination indicated, but also in other combinations or in isolation, without departing from the scope of the present invention.

In a preferred embodiment, the first elastic element with its electrically insulating property is made of an elastomer, for example natural rubber, silicone, rubber, or a TPE (thermoplastic elastomer).

The first elastic element is arranged with respect to its function as an insulator element between the at least one inner conductor and the outer conductor of the electrical contact device and is thus formed approximately sleeve-shaped. In a middle region between two end regions, which are respectively adjacent to an axial end of the first elastic element, the first elastic element preferably has a reduced rigidity.

This reduced rigidity of the first elastic element in its center region advantageously has the effect that the greatest elastic deformation of the first elastic element occurs primarily in this central region and not in the two end regions.

The reduced stiffness in the center region of the first elastic element is preferably realized by a reduced outer diameter and by a plurality of longitudinally extending slots, which are located between the outer and inner surfaces of the hollow-shaped first elastic element. As a result of these slits extending in the longitudinal axis direction, the reduced outer diameter of the central region increases in the case of a compressive force acting in the longitudinal axial direction, while the axial longitudinal extent of the middle region of the first elastic element advantageously shortens. The reduced outer diameter in the middle region can extend up to the size of the unreduced outer diameter in the end regions of the first elastic element.

An additional reduction in stiffness is achieved by having within the central region of the sleeve-shaped first elastic element on the inner and / or outer surface in each case at least one recess is provided. This at least one recess leads to an additional reduction of the cross section of the first elastic element in the region of the recess. Preferably, the individual recesses are arranged at locations of the central region, in which a deformation of the first elastic element in the radial direction occurs particularly strongly upon contraction.

Due to the reduced outer diameter, the individual slots and the individual recesses in the middle region of the first elastic element, the effective permittivity of the electrically insulating region in a section of the electrical contact device in which the middle region of the first elastic element is located is reduced compared to a section of the electrical Contact device in which the two end portions of the first elastic element are located. This increases the characteristic impedance in this section of the electrical contact device. To realize a characteristic impedance, which is advantageously adapted over the entire longitudinal extent of the electrical contact device, the outer diameter of the at least one inner conductor is increased in the middle region relative to the end regions.

In a first embodiment of an electrical contact device according to the invention, the axial variability of the outer conductor and of the at least one inner conductor is preferably realized in that the at least one inner conductor in each case from a first inner conductor part connected or contactable with the first component and a second connected or contactable with the second component Inner conductor part and the outer conductor of a connected to the first component or contactable first outer conductor part and a second component connected to the second component or contactable second outer conductor part is composed.

The first and second outer conductor part are in electrical contact with each other. They are mutually movable in the axial direction and overlap in the axial direction. Depending on the degree of overlap of the first and the second outer conductor part results in a different axial extent of the outer conductor. By increasing the degree of overlap of the first and the second outer conductor part in the case of a compression of the electrical contact device due to a contact pressure of the first and the second component on the electrical contact device, the effective axial extent of the outer conductor is reduced compared to the non-compression case. Thus, via the axial overlap of the first and the second outer conductor part, an outer conductor is realized with a variable in the axial direction extension.

Equivalently, the first and the second inner conductor part of each individual inner conductor are likewise in electrical contact with each other. They are also movable in the axial direction to each other and overlap in the axial direction. Thus, the overlapping of the first and the second inner conductor part results in each case in an inner conductor with an extent that can be changed in the axial direction.

In the case of insufficient planarity of the second component, the extent of the inner conductor that can be changed in the axial direction can be decoupled from the extent of the outer conductor that can be changed in the axial direction. For this purpose, a second elastic element is provided between the first and the second inner conductor part of the at least one inner conductor. This second elastic element realizes an elastic connection between the first and the second inner conductor part and makes it possible to compensate for an inner conductor-side axial offset between the first and the second component.

Since the first and the second inner conductor part of the at least one inner conductor are already in electrical contact with one another, as already stated above, the second elastic element need not realize any additional electrical contact between the first and the second inner conductor part. Thus, the second elastic member in this first sub-variant of the first embodiment equivalent to the first elastic member is also made of an electrically insulating material.

In a preferred first embodiment of this first sub-variant of the first embodiment, the first elastic element and the second elastic element are realized as a single common elastic element.

The electrical contact between the first and the second inner conductor part typically takes place via a plurality of spring tongues of a contacting region of the first or the second inner conductor part which are distributed on the circumference of the first or the second inner conductor part and are separated by a slot. The spring tabs of the first or the second inner conductor part are in each case connected to a contacting region on the outer surface of the respectively opposite second or first inner conductor part in a positive or non-positive connection.

The common elastic member includes a portion corresponding to the first elastic member which is outside the spring sleeve of the first or second inner conductor member, and a second elastic member corresponding portion which is located within the spring sleeve of the first or second inner conductor member. To realize the common elastic element, the common elastic element is shaped in such a way that it is passed through at least one slot of the respective spring sleeve belonging to the first or second inner conductor part. The common elastic element thus contains, in addition to the areas corresponding to the first and second elastic elements, at least one additional connecting area, which is guided in each case through a slot and connects the first and second elastic elements to one another.

Since the at least one connection region within the common elastic element is typically designed to be small-volume relative to the two regions corresponding to the first and second elastic elements, the regions of the common elastic element respectively corresponding to the first and second elastic elements are approximately decoupled from each other with regard to their elasticity ,

In a second embodiment of this first sub-variant of the first embodiment, the first and the second elastic element are each realized as non-interconnected items. In this case, the elasticities of the first and second elastic members are completely decoupled from each other.

In a second sub-variant of the first embodiment, the second elastic element is made of an electrically conductive material. In this case, the second elastic element advantageously implements not only an elastic mechanical connection, but also a further electrical contact between the first and the second inner conductor part of the respective inner conductor. As a second elastic element may in this case preferably each spring element made of a metal, for example a coil spring, use find.

In a third sub-variant of the first embodiment, in each case no second elastic element is provided between the first and the second inner conductor part of the at least one inner conductor. To realize the elasticity of the at least one inner conductor and thus the relative elastic mobility of the first and the second inner conductor part to one another, the first elastic element is additionally fixed to the at least one inner conductor.

In a second embodiment of the electrical contact device according to the invention, the axially variable extension of the outer conductor takes place in that the outer conductor is realized as an electrically conductive coating on the outer surface of the first elastic element. Preferably, a metallic coating is used as the electrically conductive coating.

In this case, upon contraction, i. in a compression, the electrical contact device due to a contact pressure of the first and the second component on the electrical contact device, not only the first elastic element, but also the outer conductor applied as a coating on the first elastic element. The completely axial extent of the outer conductor in the case of non-compression merges into axial and radial extension regions of the outer conductor in the event of compression. The effective axial extent of the outer conductor in the compression case, which results from the sum of the axial extension ranges, is thus reduced compared to the effective axial extent of the outer conductor in the non-compression case. In this way, a variable in its axial extent outer conductor is also realized.

The at least one inner conductor is in this first sub-variant of the second embodiment, as in the first embodiment of the electrical contact device according to the invention in two parts from a first component connected to the first component or contactable inner conductor part and a contactable with the second component second inner conductor part together. In the first sub-variant of the second embodiment, the characteristic impedance of the electrical contact device is adapted over the entire longitudinal extent such that in the case of compression the outer conductor extending radially outwards in the middle region is compensated by an outer diameter of the at least one inner conductor which is enlarged in the central region.

To realize the elasticity of the at least one inner conductor, a second elastic element, which is preferably embodied as an electrically conductive spiral spring, is also located between the first and the second inner conductor part of the at least one inner conductor in the first sub-variant of the second embodiment of the electrical contact device according to the invention.

In a second sub-variant of the second embodiment, analogously to the third sub-variant of the first embodiment, no second elastic element is provided in each case between the first and the second inner conductor part of the at least one inner conductor. Instead, the first elastic element is additionally fixed to the at least one inner conductor.

In addition, the inner surface of the first elastic member is in a third sub-variant of the second embodiment with a provided electrically conductive coating which serves as an inner conductor of the electrical contact device according to the invention.

Also in this case, the axial extension of the non-compressed inner conductor goes over in a compression of the electrical contact device in axially extending portions and radially extending portions. The effective axial extension of the inner conductor is reduced accordingly.

The characteristic impedance is adapted in this third sub-variant of the second embodiment over the entire axial length of the electrical contact device according to the invention in that only in the central region in compression of the electrical contact device, the changed distance between the inner and outer conductor coating by a suitable arrangement and number of slots and Recesses and compensated by a suitable dimensioning of the slot width and the slot length and the recess width and the recess depth.

In addition to the electrical contact device according to the invention, an assembly according to the invention, which includes the inventive electrical contact device, the first component connected to the electrical contact device according to the invention or contactable and the second component connected or contactable with the electrical contact device according to the invention, covered by the invention.

Finally, the invention also covers a first elastic element made of an electrically insulating material, which is set up such that it can be fixed to an outer conductor of an electrical contact device.

Embodiments and developments can, if appropriate, combine with one another as desired. Further possible refinements, developments and implementations of the invention also include combinations, not explicitly mentioned, of features of the invention described above or below with regard to the exemplary embodiments. In particular, the person skilled in the art will also add individual aspects as improvements or additions to the respective basic form of the present invention.

Other embodiments and many of the stated advantages will become apparent with reference to the drawings. The elements of the drawings are not necessarily shown to scale to each other.

In the figures of the drawing are the same, functionally identical and same-acting elements, features and components - unless otherwise stated - each provided with the same reference numerals.

In the following the figures are described coherently and comprehensively.

DESCRIPTION OF EMBODIMENTS

Before using the 6A to 6C An electrical contact device according to the invention for transmitting a differential high-frequency signal, ie a symmetrical high-frequency signal, between two components will be explained with reference to the following 1A to 5B each different forms of a coaxial contact device for transmitting an asymmetric high-frequency signal presented in detail. In this case, the first figure represents each presented sub-variant or expression of the electrical contact device in each case the operating case in which there is no electrical contact between the two components via the electrical contact device and thus the electrical contact device is not compressed. In the second figure of each presented sub-variant or expression of the electrical contact device in each case the operating case is shown, in which an electrical contact between the two components via the electrical contact device takes place and thus the electrical contact device is compressed:

In the case of a transmission of an asymmetrical high-frequency signal, the electrical contact device according to the invention is designed as a coaxial contact device. The coaxial contact device has for this purpose an outer conductor 1 and a single inner conductor 2 on, coaxial with the outer conductor 1 within the outer conductor 1 is arranged.

To achieve an electrical contact between a first component 3 , preferably a first high-frequency component, and a second component 4 , preferably a second high-frequency component, in particular in the presence of an axial offset between the first and the second component 3 and 4 is the axial extent of the outer conductor 1 and the inner conductor 2 the electrical contact device according to the invention changeable.

In a first embodiment of the electrical contact device according to the invention according to the 1A to 6C is the variable outer conductor in its axial extent 1 from a first outer conductor part 1 ₁ and a second outer conductor part 1 ₂ assembled, on the one hand to each other in an electrical contact and on the other hand in the axial longitudinal extent are mutually movable. Analogously, the changeable in its axial extent inner conductor 2 from a first inner conductor part 2 ₁ and a second inner conductor part 2 ₂ together, which are also on the one hand to each other in an electrical contact and on the other hand in the axial longitudinal extent to each other are movable. Depending on the size of the present axial offset, the first and the second outer conductor part overlap 1 ₁ and 1 ₂ and the first and second inner conductor parts 2 ₁ and 2 ₂ different lengths. The effective axial extent of the outer conductor 1 and the inner conductor 2 results from the degree of overlap of the first and the second outer conductor part 1 ₁ and 1 ₂ or of the first and the second inner conductor part 2 ₁ and 2 ₂ ,

The first outer conductor part 1 ₁ and the first inner conductor part 2 ₁ the electrical contact device according to the invention are each with associated contact surfaces on the first component 3 electrically and mechanically connected. The connection takes place here via common connection techniques, for example by means of soldering. Alternatively, the first outer conductor part 1 ₁ and the first inner conductor part 2 ₁ , as in 4A is indicated with the first component 3 only be contactable. In this case, the first outer conductor part 1 ₁ and the first inner conductor part 2 ₁ in the case of operation via an in 4A not shown device with the associated contact surfaces on the first component 3 brought into electrical contact without a permanent mechanical connection between the first outer conductor part 1 ₁ or the first inner conductor part 2 ₁ and the associated contact surfaces on the first component 3 to realize.

Equivalent are the second outer conductor part 1 ₂ and the second inner conductor part 2 ₂ the electrical contact device according to the invention with associated contact surfaces on the second component 4 contactable or by means of a common connection technology with associated contact surfaces on the second component 4 firmly connected.

At the first component 3 and the second component 4 each is preferably a high-frequency component. This high-frequency component may typically comprise a printed circuit board equipped with high-frequency electronics, a housing in which high-frequency electronics are installed, a substrate in which high-frequency electronics are integrated, or a single high-frequency component, for example a high frequency filter or a high frequency amplifier.

To realize a secure electrical contact between the first and the second outer conductor part 1 ₁ and 1 ₂ is either the first outer conductor part 1 ₁ or the second outer conductor part 1 ₂ in each case in its contact region with the respectively contacting outer conductor part 1 ₂ respectively. 1 ₁ shaped as a spring sleeve. Analog is the contact region of the first inner conductor part 2 ₁ or the second inner conductor part 2 ₂ with the respective contacting inner conductor part 2 ₂ respectively. 2 ₁ also realized as a spring sleeve to secure electrical contact between the first and the second inner conductor part 2 ₁ and 2 ₂ to realize. In the 1A . 1B and 1C is for example the second outer conductor part 1 ₂ formed in his contact area as a spring sleeve, with radially outward extensions at the distal ends of their spring tabs 5 the inner surface of the first outer conductor part 1 ₁ contacted. Inner conductor side, however, is the first inner conductor part 2 ₁ formed in his contact area as a spring sleeve, with radially inward extensions at the distal ends of their spring tabs 6 the outer surface of the second inner conductor part 2 ₂ contacted. With regard to the design of the spring tabs 6 the spring sleeve of the first inner conductor part 2 ₁ and the contact with the outer surface of the second inner conductor part 2 ₂ be on the 2A and 2 B directed.

To limit the axial mobility of the second outer conductor part 1 ₂ in the direction of the second component 4 has the first outer conductor part 1 ₁ at its distal end an inwardly directed web 7 ₁ on, as a stopper for one on the outer surface of the second outer conductor part 1 ₂ provided and radially outward web 7 ₂ serves.

Coaxial to the outer conductor 1 and to the inner conductor 2 is a first elastic element 8th arranged from an electrically insulating material. As an electrically insulating material with elasticity is preferably an elastomer, such as natural rubber, silicone, rubber, or a thermoplastic elastomer (TPE).

The first elastic element 8th is at the outer conductor 1 , preferably both on the first outer conductor part 1 ₁ as well as on the second outer conductor part 1 ₂ , fixed. To serve as fixation, as in the 1A and 1B is indicated, preferably claws 9 , respectively on the inner surface of the first and second outer conductor part 1 ₁ and 1 ₂ are formed and in associated recesses 10 at appropriate positions on the outer surface of the first elastic member 8th are hacked. Alternative fixation methods, such as bonding, are covered by the invention. Alternatively, the first elastic element 8th also only on the second outer conductor part 1 ₂ be fixed.

By fixing the first elastic element 8th at the outer conductor 1 , preferably on the first and on the second outer conductor part 1 ₁ and 1 ₂ , are the first outer conductor part 1 ₁ and the second outer conductor part 1 ₂ coupled elastically to each other. By this elastic coupling are the first and the second outer conductor part 1 ₁ and 1 ₂ mutually elastically movable. Thus, an axial extension of the outer conductor 1 feasible when contacting the second outer conductor part 1 ₂ with the second component 4 and the first outer conductor part 1 ₁ with the first component 3 to the distance between the first and second component 3 and 4 corresponds.

The first elastic element 8th is formed in the case of a coaxial contact device substantially sleeve-shaped. In a middle area 11 the sleeve-shaped first elastic element 8th that is between the two end areas 12 ₁ and 12 ₂ at the axial ends of the elastic element extends, there is an elasticity to the elasticity in the two end regions 12 ₁ and 12 ₂ is increased.

For this, the outer diameter is in the middle region 11 of the first elastic element 8th relative to the outer diameter in the two end regions 12 ₁ and 12 ₂ reduced. Besides, are in the middle area 11 of the first elastic element 8th as seen in the three-dimensional representation of the first elastic element 8th in the first embodiment of the electrical contact device according to the invention in 5 shows, extending in the axial longitudinal direction of the coaxial contact device slots 13 preferably arranged in equidistant angle sections. These slots 13 extend from the outer surface to the inner surface of the sleeve-shaped first elastic member 8th , The first elastic element preferably contains 8th two slots 13 , Alternatively, a higher number of slots may be used 13 in the first elastic element 8th present, which is covered by the invention.

Due to the reduced outside diameter and through the provided slots 13 in the middle area 11 widens with a contraction of the first elastic element 8th the diameter of the center area 11 of the first elastic element 8th while the axial longitudinal extent of the central region 11 of the first elastic element 8th shortened.

An additional increase in elasticity in the middle region 11 of the first elastic element 8th is through additional recesses 14 on the inner surface and / or on the outer surface of the central region 11 of the first elastic element 8th achieved.

The reduced outer diameter of the center region 11 of the first elastic element 8th , the slots 13 and the additional recesses 14 in the middle area 11 of the first elastic element 8th increase the characteristic impedance in the section of the electrical contact device according to the invention, in which the center region 11 of the first elastic element 8th located opposite the characteristic impedance in the sections of the electrical contact device according to the invention, in which the two end portions 12 ₁ and 12 ₂ of the first elastic element 8th are located. To compensate for this change in the characteristic impedance, the outer diameter of the first and the second inner conductor part 2 ₁ and 2 ₂ in the section of the electrical contact device according to the invention, in which the center region 11 of the first elastic element 8th located, in relation to the outer diameter of the first and the second inner conductor 2 ₁ and 2 ₂ in the sections of the electrical contact device according to the invention, in which the two end regions 12 ₁ and 12 ₂ of the first elastic element 8th are located, enlarged. In this way, the characteristic impedance of the electrical contact device according to the invention over the entire axial longitudinal extent is advantageously adapted.

Between the first and the second inner conductor part 2 ₁ and 2 ₂ is with regard to an elastic coupling of the first and the second inner conductor part 2 ₁ and 2 ₂ and thus an elastic mobility of the first and the second inner conductor part 2 ₁ and 2 ₂ to each other a second elastic element 15 intended. This second elastic element 15 is in an interior 16 arranged, which extends between the sleeve-shaped end of the second inner conductor part 1 ₂ and the shaped as a spring sleeve end of the first inner conductor part 1 ₁ located.

This second elastic element 15 is made of an electrically insulating material in the first sub-variant of the first embodiment of the electrical contact device according to the invention. It is preferably made of the same material as the first elastic element 8th , namely made of an elastomer.

In a first embodiment of the first sub-variant within the first embodiment of the electrical contact device according to the invention according to the 1A . 1B . 1C and 1D form the first elastic element 8th and the second elastic element 15 a common elastic element 17 , Here is the first elastic element 8th a first area 17 ₁ of the common elastic element 17 and the second elastic element 15 a second area 17 ₂ of the common elastic element 17 dar. The first area 17 ₁ and the second area 17 ₂ are over several connection areas 17 ₃ within the common elastic element 17 connected with each other. The connection areas 17 ₃ are each through a slot formed as a spring sleeve contact region of the first inner conductor part 2 ₁ passed.

Out 1C shows that the number of slots of the spring sleeve and thus the number of connection areas 17 ₃ between the two areas 17 ₁ and 17 ₂ of the common elastic element 17 that is the first elastic element 8th or the second elastic element 15 correspond, preferably two. But of the invention, a different number of slots of the spring sleeve and thus covered by connecting areas with.

Like from the 1A and 1B can be seen, is the axial longitudinal extent of the first elastic element 8th or common elastic element 17 at its axial ends with respect to the axial longitudinal extension of the inner conductor 2 and the outside manager 1 slightly reduced. This slight reduction of the axial longitudinal extent allows safe electrical contacting of the first inner conductor part 2 ₁ and the first outer conductor part 1 ₁ each with the first component 3 and the second inner conductor part 2 ₂ and the second outer conductor part 1 ₂ each with the second component 4 ,

In a second embodiment of the first sub-variant of the first embodiment of the electrical contact device according to the invention according to the 2A and 2 B are the first elastic element 8th and the second elastic element 15 each realized as individual parts. While in the first embodiment due to the elastic connection of the first and second elastic members 8th and 15 over the individual connection areas 17 ₃ of the common elastic element 17 still a slight coupling between the first and the second elastic element 8th and 15 is present, in the second embodiment, the first and the second elastic element 8th and 15 completely decoupled from each other elastically. The outer conductor 1 and the inner conductor 2 Thus, in the second embodiment, they have their own decoupled elasticity and, in this way, can produce non-planarity in the first component 3 and / or in the second component 4 optimally balance.

Instead of a second elastic element 15 an elastomer is also a second elastic element 15 possible, which is designed as a spiral spring made of an electrically insulating material, and covered by the invention with.

From the 2A and 2 B is always apparent that the outer diameter of the inner conductor 2 at least in a certain range of the axial longitudinal extent - here: the enlarged outer diameter of the first inner conductor part 2 ₁ in the immediate vicinity of the center area 11 of the first elastic element 8th - The inner diameter of the elastic element 8th equivalent. In this way, the inner conductor 2 from the first elastic element 8th advantageously performed in its radial positioning within the electrical contact device according to the invention.

In a second sub-variant of the first embodiment of the electrical contact device according to the invention according to the 3A and 3B becomes the realization of the elasticity of the inner conductor 2 a second elastic element 15 ' used from an electrically conductive material. In this way, in addition to the spring sleeve contact, an additional electrical contact between the first and the second inner conductor part 1 ₁ and 1 ₂ realized. Preferably, the second elastic element 15 ' made of a metal and realized as a spiral spring.

In a third sub-variant of the first embodiment of the electrical contact device according to the invention according to the 4A and 4B is on the second elastic element 15 completely omitted. In this case, the elasticity of the inner conductor 2 additionally by a further expression of the first elastic element 8th' realized. This expression of the first elastic element 8th' is not only on the outer conductor 1 , but also parallel to the inner conductor 2 fixed. In analogy to the fixation of the first elastic element 8th at the outer conductor 1 can be the fixation of the first elastic element 8th' on the inner conductor 2 preferably both on the first and on the second inner conductor part 2 ₁ and 2 ₂ respectively. Alternatively, of the invention but also the fixation of the first elastic element 8th' only on the second inner conductor 2 ₂ covered with.

The first and second inner conductor part 2 ₁ and 2 ₂ has for this purpose several distributed at equidistant angular intervals arranged claws 18 on that in associated recesses 19 of the first elastic element 8th' hack. Alternatively, other fixation methods, such as gluing or any other suitable positive or non-positive connection can be used.

Around the first elastic element 8th' the outer conductor 1 and the inner conductor 2 each imprinted elasticity at least partially decoupling from each other, are at different locations in the two end regions 12 ₁ and 12 ₂ of the first elastic element 8th' each recesses 20 intended. These recesses 20 are each completely random without the existence of any particular order within the first elastic element 8th' positioned. In this way, the first elastic element 8th' in one to the outer conductor 1 adjacent area a different elasticity than in an inner conductor 2 adjacent area on. This ensures that the outer conductor 1 one to the inner conductor 2 has different elasticity.

As in the third sub-variant, the second elastic element 15 is not needed, is for positioning the second elastic member 15 also no interior 16 between the first and the second inner conductor part 2 ₁ and 2 ₂ required. The second inner conductor part 2 ₂ must therefore no longer be sleeve-shaped at its contacting end, but can advantageously be made fully solid.

In a fourth sub-variant of the first embodiment, the electrical contact device according to the invention contains a plurality of inner conductors. According to of the 6A . 6B and 6C lie in the electrical contact device according to the invention two inner conductors 2 ¹ and 2 ² which together transmit a differential high-frequency signal (so-called twinax arrangement). The invention is not limited to two inner conductors. In addition, several pairs of two inner conductors, each transmitting a differential signal, are also covered by the invention. In the case of a star quad array of the inner conductors, for example, two pairs of two inner conductors each are arranged in a crossed relationship to one another.

According to the fourth sub-variant of the first embodiment, there are a plurality of inner conductors in the electrical contact device according to the invention, so that the arrangement between the outer conductor and the inner conductors, as from the cross section of 6B and 6C shows no more coaxiality. Also, the first elastic element is no longer coaxial with the inner and outer conductors arranged and shaped.

Like from the 6A . 6B and 6C are apparent within the outside leader 1 , which in equivalence to the previously described sub-variants and characteristics of a first and a second outer conductor part 1 ₁ and 1 ₂ composed, the spaced apart inner conductor 2 ¹ and 2 ² with their first and second inner conductor parts 2 ¹ ₁ and 2 ¹ ₂ respectively. 2 ² ₁ and 2 ² ₂ arranged.

To realize a relative elastic mobility between the first and the second outer conductor parts 1 ₁ and 1 ₂ is a first elastic element 8th'' between the outer conductor 1 and the two inner conductors 2 ₁ and 2 ² arranged and on the outer conductor 1 preferably by means of claws 9 fixed.

To the first elastic element 8th'' as a casting of an electrically insulating material, preferably made of an elastomer to be able to manufacture, are the area 21 ₁ between the two inner conductors 2 ¹ and 2 ² and the two areas 21 ₂ and 21 ₃ , each referring to the area 21 ₁ opposite between the outer conductor 1 and one of the two inner conductors 2 ¹ and 2 ² not the first elastic element 8th'' filled.

In a preferred embodiment of the fourth sub-variant of the first embodiment of the electrical contact device according to the invention, as shown in the 6A . 6B and 6C is shown, in each inner conductor 2 ¹ and 2 ² each have a second elastic element 15 ¹ and 15 ² also made of an electrically insulating material, preferably made of an elastomer provided. About the second elastic element 15 ¹ and 15 ² is an elasticity of the inner conductor 2 ¹ and 2 ² and thus a relative elastic mobility between the associated first and second inner conductor parts 2 ¹ ₁ and 2 ¹ ₂ respectively. 2 ² ₁ and 2 ² ₂ realized.

Alternatively, similar to the first embodiment of the first sub-variant of the first embodiment, a common elastic element of the first elastic element 8th'' and the two second elastic elements 15 ¹ and 15 ² conceivable and covered by the invention. Also, the realization of the two second elastic elements of an electrically conductive material, preferably as coil springs, analogous to the second sub-variant of the first embodiment and the realization without second elastic elements, wherein the first elastic element 8th'' in addition to the two inner conductors 2 ¹ and 2 ² is fixed, analogous to the third sub-variant of the first embodiment are covered by the invention.

In a second embodiment of the electrical contact device according to the invention according to the 7A to 8B is the outer conductor 1 as a coating 1' on the outer surface of the first elastic member 8th''' realized. Will the electrical contact device according to the invention and thus the first elastic element 8th''' due to contact pressure of the first and second components 3 and 4 compressed to the electrical contact device according to the invention, the diameter increases in the central region 11 of the first elastic element 8th''' with simultaneous axial shortening of the middle region 11 as shown in the three-dimensional representation of the first elastic element 8 '''in the second embodiment of the electrical contact device according to the invention in 9 evident. In the compression case, the extension of the outer conductor coating, which is completely axial in the non-compression case, proceeds 1' in radial extension regions and reduced axial extension regions. In this way, the effective axial extent of the outer conductor is reduced 1' ,

As the thickness of the outer conductor coating 11 ' is made comparatively small, is at the axial ends of the first elastic element 8th''' especially in the field of outer conductor coating 1' one contact crown each 22 intended. This contact crown 22 is with the outer conductor coating 11 ' firmly mechanically, for example by means of soldering or interference fit, connected. Thus, a secure electrical contact between the outer conductor coating 1' and the associated contact surfaces on the first and second components 3 and 4 guaranteed.

Within the sleeve-shaped first elastic element 8th''' is the inner conductor 2 arranged. The inner conductor 2 is like in the first embodiment of a first and a second inner conductor part 2 ₁ and 2 ₂ put together, each other in are in electrical contact and are elastically movable relative to each other. Like from the 7A and 7B can be removed, in this case, the second inner conductor part 2 ₂ in its contact area with the first inner conductor part 2 ₁ formed as a spring sleeve whose spring tabs the outer surface of the first inner conductor part 2 ₁ contact electrically.

In the first sub-variant of the second embodiment, the elasticity of the inner conductor is preferred 2 in analogy to the third sub-variant of the first embodiment via a second elastic element 15 ' made of an electrically conductive material, preferably via a coil spring realized. Alternatively, also a second elastic element 15 of an electrically insulating material, preferably of an elastomer, according to the second embodiment of the first sub-variant within the first embodiment conceivable and covered by the invention.

In a second sub-variant of the second embodiment, the first elastic element 8th''' in addition to the inner conductor 2 fixed according to the fourth sub-variant of the first embodiment, so that a technical solution without a second elastic element is conceivable.

Thus, in this third sub-variant of the second embodiment also of a first and a second inner conductor part 2 ₁ and 2 ₂ self-assembled inner conductors 2 through an inner conductor coating 2 ' replaced and thus saved advantageous.

To improve the electrical contact between the inner conductor coating 2 ' and the associated contact surfaces on the first and second components 3 and 4 is at the axial ends of the first elastic element 8th''' in the field of inner conductor coating 2 ' also a contact crown 23 intended. These contact crowns 23 is also via a fixed mechanical connection, for example by means of soldering or interference fit, with the inner conductor coating 2 ' connected.
