Description

CONNECTOR SYSTEM

The invention relates to a connector system having at least two connector assemblies, each comprising a socket part and a plug-in part with the socket part connectable plug.

Such connector systems are used to connect electrically conductive components, in particular electrical cables with each other. They have a plurality of socket parts, which are each mechanically and electrically releasably connectable with a complementary designed plug part. For the transmission of DC signals and AC signals relatively low frequency such connector systems have been proven. If, however, high-frequency AC signals, in particular AC signals in the gigahertz range, are to be transmitted, as used, for example, in mobile radio applications, then it is important that as far as possible no passive intermodulation (PIM) occurs, that is to say no mutual interference of electrical signals should take place which are transmitted at different frequencies. In order to achieve the lowest possible passive intermodulation, such signals are usually transmitted via coaxial cable, wherein for connecting a first coaxial cable with a second coaxial cable in each case a separate coaxial connector assembly is used, which is designed as an independent module. Such coaxial connector arrangements are known, for example, from EP 2 605 338 A1.

The transmission of high-frequency electrical signals, especially in the mobile sector, on individual coaxial connector assemblies has been proven, however, such a transmission is associated with a considerable installation effort and requires a relatively large amount of space, each with a female part of a coaxial connector assembly be able to mechanically and electrically connect a plug part of the same coaxial connector assembly.

Object of the present invention is to develop a connector system of the type mentioned in such a way that it allows transmission of electrical signals with the lowest possible passive intermodulation.

This object is achieved in a connector system of the generic type according to the invention that the connector assemblies are designed as coaxial connector assemblies whose socket parts each have an electrically conductive socket sleeve and their connector parts each insertable in the axial direction in a female sleeve and electrically connectable to the female sleeve Have a plug sleeve, wherein in the socket sleeve of the plug sleeve facing away from a first pin and the plug sleeve of the bushing sleeve side facing away from a second contact pin are inserted and in the plug sleeve an insulating part is arranged, in which an inner conductor part is positioned on the two contact pins are electrically conductively connected to each other, and wherein all the socket parts in a common, surrounded by a socket housing Buchsenisolierkörper and all the plug parts in a common seeds, surrounded by a connector housing Steckerisolierkörper are arranged and the female housing with the connector housing is releasably mechanically connected.

The connector system according to the invention forms a system of coaxial connector assemblies, which forms an independent module and over the coaxial cable electrically conductively connected to each other and the electrically conductive connection is characterized by a very low passive intermodulation. Such connector systems can be used in particular in the mobile sector.

The connector system according to the invention comprises a plurality of coaxial plug connector assemblies, each having a female part and one with the Socket part electrically conductively connectable plug part. each

Socket part comprises a bushing sleeve and each plug part comprises a plug sleeve. The bushing sleeve can with the outer conductor of a first

Coaxial cable are electrically connected, and the plug sleeve can be electrically connected to the outer conductor of a second coaxial cable. The plug sleeve can be inserted into the socket sleeve, with the insertion of an electrically conductive connection between the plug sleeve and the socket sleeve is made. An end of the first

Coaxial cable can be introduced with its inner conductor, which forms a first contact pin from the plug sleeve facing away from the axial side into the socket sleeve, and in a corresponding manner, the inner conductor of the second coaxial cable, which forms a second contact pin, from the sleeve side facing away from the sleeve be inserted in the axial direction in the connector sleeve. The two contact pins can be inserted into recesses of an inner conductor part and connected to each other via this electrically conductive. The inner conductor part is held in an insulating part which is arranged in the plug sleeve.

Each of the coaxial connector assemblies of the connector system of the invention allows the transmission of electrical signals with very little passive intermodulation. In order to avoid mutual interference of the coaxial connector assemblies, all of the female parts of the coaxial connector assemblies are disposed in a common female insulating body, and all male parts of the coaxial connector assemblies are disposed in a common male insulating body. The female insulating body and / or the male insulating body may be made of the same material as the insulating member disposed in each male sleeve. In particular, it can be provided that the female insulating body and / or the Steckerisolierkörper are made of a polytetrafluoroethylene material.

The female insulating body is arranged according to the invention in a female housing and the Steckerisolierkörper is in a connector housing ange- assigns, and the two housings are releasably mechanically connected to each other. It has been found that by providing the female insulating body accommodating all the female parts and the male insulating body accommodating all the male parts and providing the female housing surrounding the female insulating body and the male housing surrounding the male insulating body, the deterioration of the Signal transmission over the individual coaxial connector assemblies can be kept very low. The connector system according to the invention is therefore characterized by a possibly very low passive intermodulation, wherein at least two pairs of coaxial cables can be electrically connected to one another in a simple manner. The connector system according to the invention can in this case be exposed to very harsh environmental conditions, without affecting the transmission of the electrical signals. This is ensured in particular by the provision of the female housing and the connector housing, which give the connector system a high mechanical strength and also ensure that the individual parts of the socket can not inadvertently come loose from the respective associated connector part. The mechanical connection of the female housing to the male housing, in combination with the female insulating body and the male insulating body, ensures that the individual male parts are respectively fixed reliably and practically immovably in the associated female part.

The connector system according to the invention comprises at least two coaxial plug connector assemblies, so that at least two pairs of

Coaxial cables can be interconnected. However, the connector system according to the invention is not limited to the use of at least two coaxial connector assemblies. It can also be more than two coaxial connector assemblies are used, for example, three, four, five or more coaxial connector assemblies, each having a female part and with this electrically and mechanically releasably connectable plug part, wherein all the socket parts in a common, from a Socket housing surrounded Buchsenisolierkörper are arranged and wherein all connector parts are arranged in a common, surrounded by a plug housing Steckerisolierkörper.

It is advantageous if the plug housing and / or the socket housing forms a metallic shield. For example, it may be provided that the plug housing and / or the socket housing, in particular on its outer side have a metallic coating or are made of metal, such as an aluminum alloy or stainless steel, for example. The provision of a metallic shield by the plug housing and / or the socket housing has the particular advantage that the transmission of electrical signals via the individual coaxial connector assemblies is not affected by external electromagnetic fields.

It is particularly favorable if the plug housing and / or the socket housing are designed as metal housings. In such an embodiment, the plug housing and / or the socket housing are made entirely of metal, for example of an aluminum alloy or stainless steel. This allows a cost-effective production and gives the connector system according to the invention a particularly high mechanical strength and insensitivity to the external environment.

As already mentioned, the plug housing with the socket housing is releasably mechanically connected. In a preferred embodiment of the invention, the plug housing can be screwed to the socket housing. The plug housing and the socket housing have for this purpose complementary to each other configured thread. For example, it can be provided that the connector housing has an internal thread which can be screwed onto a complementary ausgestaltetes external thread of the female housing.

In an advantageous embodiment of the invention, the plug housing with the socket housing is pluggable connectable. It is advantageous if the plug housing is detachably lockable with the socket housing. For locking, a locking element movably mounted on the socket housing or on the plug housing is favorably used, which can be moved back and forth between a locking position and a release position. In its locking position, the locking element ensures that the female housing can not be separated from the male housing, and in the release position, the locking element allows separation of the female housing from the male housing. A separation may be provided, for example, for assembly purposes.

It is particularly advantageous if a locking hook pivotable back and forth between a release position and a locking position is mounted on one of the two housings, and on the other of the two housings a locking projection engageable by the locking hook in the locking position is arranged. By means of the locking hook can be ensured in a simple manner that the connector housing does not inadvertently detached from the socket housing. For this purpose, it is only necessary to transfer the locking hook in its locking position. In the locking position, the locking hook engages behind a locking projection associated therewith.

The locking projection may be designed, for example, in the manner of a pin, in particular a mushroom-shaped pin, which can be engaged behind by the locking hook.

The locking hook is conveniently rigidly connected to an actuator that can be grasped by the user to pivot the locking hook.

It is advantageous if the actuator is integrally connected to the locking hook. In particular, it can be provided that the actuating member and the locking hook together form a one-piece component form, which is pivotally mounted on the connector housing or on the socket housing.

The Buchsenisolierkörper and Steckerisolierkörper are cylindrical or cuboid in an advantageous embodiment of the invention. A cuboid design makes it possible to design the plug connector system according to the invention as flat as possible, wherein a plurality of coaxial plug connector assemblies are arranged in a row next to each other. A cylindrical configuration of the female insulating body and the male insulating body makes it possible to arrange a plurality of coaxial connector assemblies along the circumference of an imaginary circle. The coaxial connector arrangements can be arranged uniformly distributed over the circumference of the imaginary circle. For example, it can be provided that four coaxial connector assemblies are each offset by 90 ° to each other over the circumference of the imaginary circle.

It is particularly advantageous if the Buchsenisolierkörper forms an end stop to which the Steckerisolierkörper can be applied in the axial direction. In such an embodiment of the invention, the Buchsenisolierkörper is directly on the Steckerisolierkörper as soon as the mechanical connection between the female housing and the connector housing is made. The Buchsenisolierkörper and Steckerisolierkörper are thus fixed to each other in the axial direction, so that unintentional movements of the two insulator are avoided relative to each other and the highest possible mechanical stability is achieved. The passive intermodulation is influenced, among other things, by the stability of the mechanical connection between the female parts and the male parts. In order to obtain the highest possible mechanical stability, it is advantageous if the bushing insulating body surrounding all the bushing parts rests in the axial direction directly on the plug insulating body surrounding all plug parts.

The end stop of the female insulating body is in an advantageous embodiment of the invention of the front of the Steckerisolierkörper facing formed side of Buchsenisolierkörpers. In such an embodiment, the Steckerisolierkörper can thus be applied directly to the facing him end face of Buchsenisolierkörpers.

In a particularly preferred embodiment of the invention, the Steckerisolierkörper can be acted upon with an axial force in the direction of the Buchsenisolierkörper and / or the Buchsenisolierkörper can be acted upon with an axial force in the direction of the Steckerisolierkörper. The application of the axial force can be effected, for example, by mechanically connecting the plug housing to the socket housing, wherein the plug insulation body is acted upon by the plug housing with an axial force in the direction of the socket insulation body and / or the socket insulation body by an axial force in the socket housing Direction is applied to the Steckerisolierkörper. It may alternatively be provided, for example, that a locking hook exerts an axial force on one of the two insulating body by the engagement of an associated locking projection, which is transmitted from this insulating body to the other of the two insulating body. The application of an axial force counteracts any micromotion of the plug insulation body relative to the socket insulation body and thereby improves the electrical transmission quality that can be achieved by means of the connector system according to the invention.

As already mentioned, the plug sockets can each be inserted into a socket sleeve. In a particularly preferred embodiment of the invention, each of the plug sleeves contacted in the inserted state, the associated sleeve sleeve only in at least one extending in the circumferential direction of the connector sleeve contact area of the female sleeve, and the connector sleeve is acted upon by Steckerisolierkörper with an axial force in the direction of the sleeve sleeve, said arranged in the connector sleeve insulating member bears with a projecting in the axial direction over the free end of the plug sleeve contact surface on the female sleeve. In such an embodiment of the invention, the plug sleeve of each coaxial connector assembly tion in the inserted state only in at least one contact area extending in the circumferential direction of the plug sleeve, electrically connected to the associated sleeve sleeve, an electrical contact on the front side of the plug sleeve is avoided, however, by the arranged in the plug sleeve insulating part over the free end of the plug sleeve protrudes and forms a stop surface, which rests in the inserted state of the plug sleeve on the associated sleeve sleeve. The front in the insertion of the insulating part thus forms a spacer, which ensures a distance between the free end of the plug sleeve and the associated sleeve sleeve in the inserted state of the respective plug sleeve, an electrical contact on the front side of the plug sleeve is avoided by the spacer. A basic problem of an end-to-end contacting is that, due to uneven surfaces on the front sides as well as micro-movements between the front sides, undefined contacts can occur, which considerably impair passive intermodulation. It has been found that by a radial contact, that is. by contacting over a circumferentially extending contact area, and by avoiding micro-movements between the connector sleeves and the female sleeves, the passive intermodulation of a coaxial multiple connector can be kept particularly low. In order to avoid an axial movement of the plug sleeve relative to the bushing sleeve, the plug sleeve is acted upon by Steckerisolierkörper with an axial force in the direction of the bushing sleeve. The force ensures that the over the free end of the plug sleeve protruding end of the insulating member maintains its position on the female sleeve, the insulating part is thus pressed by Steckerisolierkörper against the female sleeve. When inserting the plug sleeve into the socket sleeve, the bushing sleeve forms, for example with a bottom wall a stop on which abuts the projecting beyond the free end of the plug sleeve stop surface of the insulating before the free end of the plug sleeve can contact the bottom wall of the sleeve sleeve in the axial direction. It is advantageous if the insulating part arranged in the plug sleeve bears against the plug sleeve with a rear stop face facing away from the socket sleeve, preferably on an inner shoulder of the plug sleeve. In such an embodiment, the insulating parts of each coaxial connector arrangement of the connector system according to the invention are clamped under the action of the axial force of the Steckerisolierkörpers each between a plug sleeve and a female sleeve. This increases the mechanical strength of the coaxial connector assemblies and avoids axial movement of the male connectors relative to the female sleeves.

It is particularly advantageous if each of the plug sleeves, in the inserted state, electrically contacts the assigned socket sleeve only in a single contact area, wherein the contact area is arranged on an inner side of the socket sleeve and surrounds the respective plug sleeve in the circumferential direction. Such a configuration is characterized by a particularly low passive intermodulation, because unintentional relative movements of the connector sleeves relative to the respective associated sleeve sleeve in the axial direction and also in the circumferential direction result in such a configuration at best very little impairment of the electrical transmission quality of the connector system.

The contact area of the bushing sleeves extending along the circumference of each plug sleeve is expediently configured as a cylindrical wall section of the bushing sleeves.

In an advantageous embodiment of the invention, a wall section of the bushing sleeve that widens conically towards the free end of the bushing sleeve adjoins the cylindrical wall section of the bushing sleeves, into which the respective plug bush plunges, the conically widening wall section and the plug bushing between them Define annulus. At the flared wall portion of the female sleeves can connect in the direction of the free end of the female sleeves each have a cylindrical wall portion of the female sleeves.

The bushing sleeves are rigidly formed in an advantageous embodiment of the invention, so that they can not be practically deformed in the radial and axial directions.

It is advantageous if the Steckerisolierkörper has on its the female insulating facing end side a plurality of this end face protruding extension rings, each surrounding a plug sleeve in the circumferential direction and inserted into a female sleeve, in particular be pressed. If the plug housing is connected to the socket housing, the extension rings arranged on the end face of the plug insulation body facing the socket insulation body respectively dip into a socket sleeve, wherein they are preferably pressed together with the socket sleeve and are thereby mechanically fastened to the respective socket sleeve. Unintentional micro-movements of the Steckerisolierkörpers relative to the female sleeves can be kept particularly low.

It is advantageous if the respective plug sleeves enclosed by an extension ring can be pressed into the extension rings. This facilitates the assembly of the plug sleeves on Steckerisolierkörper and gives the connector system a particularly high mechanical strength.

As already mentioned, the electrical transmission quality of the connector system can be affected by unintentional movements of the connector sleeves relative to the female sleeves. In order to keep such impairments particularly low, in an advantageous embodiment of the connector system, the coaxial connector arrangements each have a spring element which can be clamped in the axial direction between a support surface of the socket sleeve and a support surface of the plug sleeve. By using the spring elements unintentional micromotion of the Plug sleeves are kept particularly low relative to the female sleeves. The spring elements also act as a tolerance compensation, which compensates for manufacturing inaccuracies of the plug sleeves and the socket sleeves.

It is advantageous if the spring elements can be clamped not only in the axial direction but also in the radial direction between two mutually facing support surfaces of a plug sleeve and a socket sleeve. This has the advantage that each spring element can act on a plug sleeve and a sleeve sleeve both with an axial spring force and with a radial spring force. As a result, any micro-movements of the connector sleeves can be counteracted particularly effective relative to the female sleeves.

Each spring element is favorably supported on radially oriented steps of a plug sleeve and a bushing sleeve. For example, it can be provided that the spring element is supported on the one hand on a shoulder of the plug sleeve and on the other hand on a radially oriented step of the sleeve sleeve.

It is advantageous if the spring elements are each arranged on the inside of a bushing sleeve and surround a plug sleeve in the circumferential direction.

The spring elements are conveniently designed as annular elastomeric parts. In such an embodiment, each spring element is made of an elastomeric material, which ensures elastic deformation of the spring element in a structurally simple manner. The elastomer part is formed in the manner of a ring and can take a position between the support surface of the female sleeve and the support surface of the connector sleeve when inserting a connector sleeve in the associated sleeve sleeve.

It is particularly advantageous if an extending between the plug sleeve and the sleeve sleeve each coaxial connector assembly Annular space can be sealed by means of a spring element. The spring element has in such an embodiment of the invention in addition to its resilient function on a sealing function by avoiding the ingress of moisture and dirt particles in each extending between a plug sleeve and a sleeve sleeve annulus.

The spring elements are configured in a preferred embodiment of the invention as an O-ring or in the form of a sealing sleeve. The sealing sleeves form a cylinder jacket, which bears against the inside of a female sleeve and surrounds the associated connector sleeve in the circumferential direction.

In the figures 1 to 4, a first advantageous embodiment of a connector system according to the invention is shown schematically and overall occupied by the reference numeral 10. The connector system 10 includes a connector housing 12, which is designed in the illustrated embodiment as a union nut and has an internal thread 14. In addition, the connector system 10 includes a female housing 16, which forms a flange 18 in the illustrated embodiment, which can be bolted, for example, with a housing, not shown in the drawing to achieve a better overview of an electrical component.

The plug housing 12 surrounds a Steckerisolierkörper 20, which is made of an electrically insulating material, for example of a polytetrafluoro ethylene material, and four identically designed connector parts 22, 24, 26, 28 receives.

The female housing 16 surrounds a Buchsenisolierkörper 30, the four identically designed socket parts 32, 34, 36, 38 surrounds. In each case a plug part 22, 24, 26, 28 forms in combination with an associated socket part 32, 34, 36, 38 a in Fig. 3 schematically shown in a longitudinal section coaxial connector assembly 40th

The plug parts 22, 24, 26, 28 each comprise a plug sleeve 48 and the socket parts 32, 34, 36, 38 each comprise a bushing sleeve 50. All plug sleeves 48 as well as the associated socket sleeve 50 of an electrically conductive material, in particular of metal, manufactured.

The Steckerisolierkörper 20 has on its the Buchsenisolierkörper 30 facing end face 52 four identically designed extension rings 54 which are integrally connected to the Steckerisolierkörper 20 and together with the Steckerisolierkörper 20 a one-piece, electrically insulating forming component. The plug sleeves 48 are each pressed into one of the extension rings 54, wherein the extension rings 54 each surround a central portion 62 of a plug sleeve 48 in the circumferential direction. At the central portion 62, a collar-shaped rear end portion 64 of the plug sleeve 48 connects, which dips into a Steckerisolierkörper 20 in the axial direction sweeping through passage 66. The rear end portion 64 forms a cylinder jacket into which a first coaxial cable 68 can be inserted. Of the first coaxial cable 68, only one end portion is shown in FIG. The first coaxial cable 68 has in the usual way an inner conductor 70 and an outer conductor 72, between which a dielectric 74 is arranged. The exposed outer conductor 72 is electrically conductively connected to the plug sleeve 48 in the region of the rear end portion 64. In particular, it can be provided that the outer conductor 72 is soldered to the plug sleeve 48. The exposed inner conductor 70 protrudes in the axial direction into the central portion 62 of the plug sleeve 48 and forms a first contact pin 76th

The Steckerisolierkörper 20 has a total of four identically configured through-channels 66, in each of which a plug sleeve 48 dips and through which a first coaxial cable can be passed.

In the rear end portion 64 of the plug sleeve 48 facing away from the direction closes at the central portion 62 of the plug sleeve 48 via a radially inwardly directed step 78, a front end portion 80 of

Plug sleeve 48 on. The front end portion 80 is conical and tapers continuously in the direction away from the central portion 62 forward direction. At its front end, the front end portion 80 carries a circumferentially extending annular bead 82.

The front end portion 80 is formed by a plurality of spring tongues 84, between each of which an axial slot 86 extends, which divides the annular bead 82 into individual annular bead portions 88. In the area of the spring tongues 84, the plug sleeve 48 is elastically deformable in the radial direction. The plug sleeve 48 surrounds with its central portion 62 and with its front end portion 80, an insulating member 90 which, like the Steckerisolierkörper 20 and the female insulation 30 is made of an electrically insulating material, in particular of a Polytetrafluorethylenmaterial. With a rear abutment surface 92, the insulating part 90 bears against an inner shoulder 94 of the plug sleeve 48, and with a front abutment surface 96, the insulating part 90 protrudes beyond the free end of the plug sleeve 48 and bears against a bottom wall 98 of the female sleeve 50.

The bushing sleeve 50 has a central portion 100 to which a collar-shaped rear end portion 102 adjoins in the direction away from the plug sleeve 48, which penetrates into a passage 104 passing through the bush insulating body 30 in the axial direction. The rear end portion 102 forms a cylinder jacket into which a second coaxial cable 106 is inserted. For clarity, only one end portion of the second coaxial cable 106 is shown in the drawing. The second coaxial cable 106 has in the usual way an inner conductor 108 and an outer conductor 110, between which a dielectric 112 is arranged. The exposed outer conductor 110 is electrically conductively connected to the bushing sleeve 50 in the region of the rear end section 102. In particular, it can be provided that the outer conductor 110 is soldered to the bushing sleeve 50. The exposed inner conductor 108 projects in the axial direction into the bushing sleeve 50 and forms a second contact pin 114.

The Buchsenisolierkörper 30 has a total of four identically configured passageways 104, in each of which a socket sleeve 50 dips and through which a second coaxial cable can be passed.

At the central portion 100 of the sleeve sleeve 50 is followed by a radially outwardly directed step 116, a front end portion 118 at. The inner diameter of the front end portion 118 is set larger than the outer diameter of the central portion 62 of the plug sleeve 48 and the Middle labschnitt 62 and the plug sleeve 48 circumferentially surrounding extension ring 54 is pressed into the front end portion 118 of the sleeve sleeve 50.

The middle section 100 of the bushing sleeve 50 forms on its inner side a first cylindrical wall section 120 adjoining the bottom wall 98, to which a conical wall section 122 adjoins in the direction facing away from the bottom wall 98, which via a radially outwardly directed step 124 into one second cylindrical shell portion 126 passes. The second cylindrical shell portion 126 extends to the free end of the front end portion 118.

In the area between the radially outwardly directed step 124 of the bushing sleeve 50 and the radially inwardly directed step 78 of the plug sleeve 48, a sleeve-shaped spring element 128 is arranged on the inside of the bushing sleeve 50, which between the radially outwardly directed step 124 and the radially internally directed step 78 is clamped. The spring element 128 is made of an elastomeric material and therefore elastically deformable. A between the conical wall portion 122 of the sleeve sleeve 50 and the spring tongues 84 of the plug sleeve 48 extending annular space can be sealed by means of the spring member 128 to prevent the ingress of moisture and dirt particles.

The central portion 100 of the female sleeve 50 is as well as the adjoining front end portion 118 of the female sleeve 50 is pressed into the passageway 104 of the female insulating 30. At the level of the radially outwardly directed step 116 of the bushing sleeve 50, the passageway 104 has a radial extension 130, at which the radially outwardly directed step 116 of the bushing sleeve 50 is supported in the axial direction.

The insulating part 50 arranged in the plug sleeve 48 has a through bore aligned coaxially to a longitudinal axis 132 of the coaxial plug connector arrangement 40 in which an electrically conductive inner conductor part 134 is arranged. The inner conductor part 134 has, facing the first coaxial cable 68, a first blind hole-like recess 136 and facing the second coaxial cable 106, the inner conductor part 134 has a second blind hole-like recess 138. The first contact pin 76 dips into the first recess 136 of the inner conductor part 134 and is electrically conductively connected to the inner conductor part 134. In particular, it can be provided that the first contact pin 76 is soldered to the inner conductor part 134 in the region of the first recess 136. For this purpose, a solder depot not shown in the drawing can be arranged in the first recess 136.

If the female housing 12 mechanically connected to the connector housing 18, then each connector sleeve 48 so far immersed in the associated sleeve sleeve 50 that the front abutment surface 96 of the insulating 90 abuts against the bottom wall 98 of the female sleeve 50, and the second contact pin 114 dives into the second recess 138 of the inner conductor part 134, wherein an electrically conductive connection is made between the second contact pin 114 and the inner conductor part 134. The first contact pin 76 is then electrically conductively connected via the inner conductor part 134 with the second contact pin 114. At the same time, the outer conductor 72 of the first coaxial cable 68 is electrically conductively connected via the electrically conductive plug sleeve 48 and the annular bead 82 to the socket sleeve 50, whose rear end portion 102 is in turn electrically conductively connected to the outer conductor 110 of the second coaxial cable 106.

The electrically conductive connection of each plug sleeve 48 and the associated sleeve sleeve 50 is exclusively on the annular bead 82 of the plug sleeve 48 and the first cylindrical wall portion 120 of the sleeve sleeve 50. An electrical connection in the axial direction between the plug sleeve 48 and the sleeve sleeve 50 is through the insulating part 90 prevented with the projecting beyond the free end of the plug sleeve 48 front

Stop surface 96 abuts against the bottom wall 98, so that the free end of the plug sleeve 48 in the inserted state in the axial direction at a distance from the bottom wall 98 occupies. If the plug housing 12 is mechanically connected to the socket housing 16, then the plug sockets 48 of the four coaxial plug connector assemblies 40 each dip into a socket sleeve 50, the extension rings 54 being respectively pressed into a front end portion 118 of a socket sleeve 50 the end face 52 of the plug insulating body 20 rests against the end of the plug insulating body 30 facing the plug insulating body 20. The end face 140 of the female insulating body 30 thus forms an end stop for the Steckerisolierkörper 20. By making the mechanical connection between the connector housing 12 and the female housing 16, the male insulating body 20 is pressed against the female insulating body 30, and this in turn causes the male sleeves 48 to be pressed into the female sleeves 50 and thereby the insulating members 90 with their front abutment surface 96 each abut a bottom wall 98. In this case, the spring elements 128 are compressed in the axial direction. The plug sleeves 48 are fixed immovably in the socket sleeves 50, so that even mechanical effects that can act on the connector system 10 from the outside, for example, weather conditions, cause virtually no micromotion of the plug sleeves 48 relative to the bushing sleeves 50. Even very high-frequency electrical signals can be transmitted with very good transmission quality via the connector system 10. The connector system 10 is characterized by a very low passive intermodulation.
