Description

COAXIAL CONNECTOR ARRANGEMENT

The invention relates to a coaxial connector assembly having an electrically conductive outer sleeve and an axially insertable into the outer sleeve and electrically connectable to the outer sleeve electrically conductive inner sleeve, wherein in the outer sleeve of the inner sleeve side facing away from a first contact pin and in the inner sleeve of the the outer sleeve facing away from a second contact pin are inserted, and wherein in the inner sleeve, an insulating part is arranged, in which an inner conductor part is held, and the two contact pins are electrically conductively connected to each other via the inner conductor part.

Coaxial connector arrangements of the type mentioned are used to make an electrical connection between a first coaxial cable and a second coaxial cable or between a coaxial cable and other electrical assembly. An end portion of the first coaxial cable can be inserted with its inner conductor, which forms a first contact pin, from the inner sleeve facing away from the axial side into the outer sleeve, and in a corresponding manner, the inner conductor of a second coaxial cable, which forms a second contact pin, from the the outer sleeve facing away from the axial direction are introduced into the inner sleeve. The two contact pins can usually be inserted into recesses of the inner conductor part and connected to each other via this electrically conductive. The outer conductors of the two coaxial cables can be electrically connected to the outer sleeve or with the inner sleeve, for example by means of a solder joint, and then the inner sleeve can be inserted into the outer sleeve, wherein the inner sleeve electrically contacts the outer sleeve and thereby an electrical connection is made between the outer conductors the two coaxial cables. In the same way, by means of such coaxial connector arrangements, a coaxial cable can also be connected to an electrical module become. In this case, the electrical module provides one of the two contact pins and the coaxial cable provides the other contact pin with the end region of its inner conductor. The contact pin of the electrical assembly can be electrically connected via the inner conductor part with the contact pin of the coaxial cable and corresponding outer conductor of the module and the coaxial cable can be electrically conductively connected to each other via the outer sleeve and the inner sleeve.

It is important for the operating behavior of the coaxial plug connector arrangements that as far as possible no passive intermodulation (PIM) occurs, that is to say that as far as possible mutual interference of electrical signals which are transmitted at different frequencies via the coaxial plug connector arrangements should not take place. Among other things, passive intermodulation is influenced by the stability of the mechanical connection between the inner sleeve and the outer sleeve. In order to obtain the highest possible mechanical stability, therefore, in many cases, the inner sleeve is screwed into the outer sleeve. The screw connection reduces the risk that the inner sleeve moves relative to the outer sleeve and thereby the electrical transmission quality is impaired. However, the provision of a screw connection is associated with not inconsiderable production costs and makes it difficult to handle such coaxial connector arrangements.

In DE 10 2011 056 466 AI a locking connection between the inner sleeve and the outer sleeve is proposed, wherein an electrical contact between the inner sleeve and the outer sleeve takes place only in the radial direction along the circumference of the inner sleeve, a contacting of the inner sleeve with the outer sleeve in axial direction, ie in particular on the end face of the inner sleeve is avoided. The electrical connection is made on the one hand via an annular sleeve arranged on the inner sleeve and on the other via a spaced apart from the annular bead radial expansion of the inner sleeve. The radial enlargement serves at the same time to produce a latching connection between the inner sleeve and the outer sleeve. in the region of the radial extension an annular groove is arranged, in which an annular locking projection of the outer sleeve dips.

The object of the present invention is to develop a coaxial connector arrangement of the type mentioned at the outset in such a way that it has simple handling and low passive intermodulation.

This object is achieved in a coaxial connector assembly of the generic type according to the invention in that the coaxial connector assembly has a locking element, which can be mounted on one of the two sleeves prior to insertion of the inner sleeve in the outer sleeve and during or after insertion of the inner sleeve the outer sleeve is pushed onto the other of the two sleeves, wherein the inner sleeve by means of the locking element in the outer sleeve is releasably fixable.

In the case of the coaxial connector assembly according to the invention, a locking element is used in addition to the inner sleeve and the outer sleeve, with the aid of which the inner sleeve can be fixed in the outer sleeve and, if required, released again from the outer sleeve. The locking element thus reduces the risk that moves the inner sleeve after insertion relative to the outer sleeve and thereby the electrical transmission quality of the coaxial connector assembly is adversely affected. The coaxial connector assembly according to the invention is therefore characterized by a low passive intermodulation.

In the coaxial connector assembly according to the invention, the locking element can be mounted in a first assembly step on the inner sleeve or on the outer sleeve. If the inner sleeve is subsequently inserted into the outer sleeve, then the locking element can be pushed onto the other of the two sleeves in order to fix the two sleeves relative to one another. The locking element can already occupy its end position when inserting the inner sleeve on the outer sleeve, or it can after the Successful insertion of the inner sleeve are moved into the outer sleeve in its final position.

In the coaxial connector assembly according to the invention can therefore be provided, for example, that the locking element is first preassembled on the inner sleeve. If the inner sleeve is then inserted into the outer sleeve, then the locking element is slid so far onto the outer sleeve in the axial direction that a releasable mechanical connection between the inner sleeve and the outer sleeve is achieved by means of the locking element for fixing the inner sleeve in the outer sleeve.

It can also be provided that the locking element is first preassembled on the outer sleeve. If the inner sleeve is then inserted into the outer sleeve, then the locking element is pushed against the insertion direction of the inner sleeve so far on the inner sleeve, that by means of the locking element a releasable mechanical connection between the inner sleeve and the outer sleeve is achieved for fixing the inner sleeve in the outer sleeve.

It is advantageous if the locking element before insertion of the inner sleeve in the outer sleeve either on the inner sleeve or on the outer sleeve mountable and during or after insertion of the inner sleeve in the outer sleeve on the other of the two sleeves can be pushed, because this facilitates the Assembly of the coaxial connector assembly, since the user has the ability to choose the optimal for the particular application, pre-assembly of the locking element.

Conveniently, the inner sleeve by means of the locking element in the outer sleeve rotatably fixed.

It is advantageous if the inner sleeve by means of the locking element in the outer sleeve is axially immovable and rotationally fixed. A particularly simple pre-assembly of the locking element optionally on the inner sleeve or on the outer sleeve is achieved in an advantageous embodiment of the invention in that the locking element is pushed onto one of the two sleeves prior to insertion of the inner sleeve into the outer sleeve. In such an embodiment of the invention, the locking element can thus be pushed in a first step, for example, on the inner sleeve and then pushed onto the outer sleeve during insertion of the inner sleeve in the outer sleeve. But the user also has the option to postpone the locking element in a first step on the outer sleeve. If the inner sleeve is then inserted into the outer sleeve, then the locking element is also pushed onto the inner sleeve in order to releasably fix it in the outer sleeve.

It is advantageous if the locking element after insertion of the inner sleeve in the outer sleeve surrounds at least one of the two sleeves, in particular both sleeves in the circumferential direction. In such an embodiment, the locking element forms a jacket, for example a cylinder jacket, which completely surrounds at least one of the two sleeves in the circumferential direction after the inner sleeve has been inserted into the outer sleeve. The locking element expediently surrounds both sleeves after the inner sleeve has been inserted into the outer sleeve. This has the advantage that the outer sleeve and the inner sleeve are protected in the area surrounded by the locking element from environmental influences and mechanical impairments.

It is advantageous if the locking element surrounds the inner sleeve and / or the outer sleeve in an electrically insulating manner.

In an advantageous embodiment of the invention, the locking element with the inner sleeve and / or with the outer sleeve is releasably latched. It can be provided, for example, that the locking element can be pushed onto one of the two sleeves for pre-assembly and locked with this sleeve. Afterwards, the locking element can cken the inner sleeve pushed into the outer sleeve and the other of the two sleeves and conveniently be locked releasably with this.

In a preferred embodiment of the invention, the locking element has a plurality of latching wings which are distributed over the circumference of the locking element and engage with associated latching elements of the inner sleeve and / or the outer sleeve. The latching wings are deformable in the radial direction and are distributed over the circumference of the locking element. For example, it can be provided that the locking element has three circumferentially spaced apart locking wings. The latching wings each cooperate with an associated latching element in the sense of a latching connection. The latching elements may be formed, for example, in the form of latching recesses into each of which a latching wing with a latching nose dips. The latching elements can be arranged on the inner sleeve, so that the locking element can be latched by means of the latching wings with the inner sleeve. Alternatively or additionally, it may be provided that the latching elements are arranged on the outer sleeve, so that the locking element can be latched to the outer sleeve.

It is particularly advantageous if the locking element has a plurality of first latching wings, which dive into a region between the inner sleeve and the outer sleeve and latch with locking elements which are arranged on the inside of the outer sleeve. The locking elements may in this case be designed in the form of a common annular groove, which is arranged on the inside of the outer sleeve.

Conveniently, the locking element comprises a plurality of second latching wings which are arranged distributed over the circumference of the locking element and engage with latching elements which are arranged on the outer side of the inner sleeve. It is advantageous if the arranged on the outside of the inner sleeve locking elements together over the entire

Form the circumference of the inner sleeve extending annular collar. The second stop wings can each have a recess, into which the collar dips.

Preferably, the first and second locking elements are arranged alternately in the circumferential direction of the locking element. In the circumferential direction thus follows a first latching wing, which cooperates with an internally arranged on the outer sleeve latching element, a second latching wing, which cooperates with a locking element arranged on the outside of the inner sleeve.

It is advantageous if the locking element is at least partially elastically and / or plastically deformable in the radial direction. For pre-assembly on one of the two sleeves and / or sliding on the other of the two sleeves, the locking element can be elastically and / or plastically deformed in such a configuration of the invention, at least in individual areas in the radial direction.

It is particularly advantageous if the locking element can be pressed onto the inner sleeve and / or onto the outer sleeve and / or can be pressed in between the inner sleeve and the outer sleeve. It can thus be achieved between the outer sleeve and the locking element and / or between the inner sleeve and the locking element a press connection.

In a preferred embodiment of the invention, the locking element has a plurality of spring tongues. The spring tongues make it possible to deform the locking element in a structurally simple manner in the radial direction inwards and / or outwards. Such a deformation is particularly advantageous when the locking element is pushed onto the inner sleeve or to the outer sleeve for pre-assembly.

It is advantageous if the locking element engages behind a holding surface of the inner sleeve and / or the outer sleeve in the axial direction. This increases the mechanical strength of the mechanical connection between the inner sleeve and the outer sleeve, which is achieved by means of the locking element. The holding surface is advantageously aligned perpendicular to the longitudinal axis of the coaxial connector assembly.

It can be provided, for example, that the inner sleeve and / or the outer sleeve have a radially outwardly facing step, to which the locking element can be applied with a cross-engaging portion.

A particularly simple handling is achieved in a preferred embodiment of the invention in that the locking element is mounted on the inner sleeve and the outer sleeve without tools. For pre-assembly of the locking element on one of the two sleeves and also for the final assembly of the locking element on both sleeves it is not necessary in such an embodiment of the invention any special tool.

It may be provided that the locking element for pre-assembly initially pressed onto the outer sleeve and / or can be locked to the outer sleeve, and that the locking element when inserting the inner sleeve in the outer sleeve also pressed onto the inner sleeve and / or can be locked to the inner sleeve ,

It can also be provided that the locking element can first be pressed onto the inner sleeve and / or latched to the inner sleeve, and that when inserting the inner sleeve in the outer sleeve, the locking element can also be pressed onto the outer sleeve or locked with the outer sleeve.

Conveniently, the locking element has a plurality of deformable press vanes spaced apart in the circumferential direction of the locking element, which can be pressed in between the inner sleeve and the outer sleeve. The press wings are arranged in the circumferential direction of the locking element at a distance from each other. For example, it can be provided that the locking element three over the circumference of the locking element having uniformly distributed squeeze wings. Conveniently, the press wings in the circumferential direction each extend over an angular range of about 40 ° to 60 °.

It is advantageous if the radial extent of the press wings before being pressed into a receiving space extending between the inner sleeve and the outer sleeve is at least partially larger than the radial extent of the receiving space. In such an embodiment, the squeeze wings have an excess and are compressed upon insertion into the receiving space. The press wings are elastically or plastically deformable for this purpose.

It can be provided that the presser wings before pressing in the extending between the inner sleeve and the outer sleeve receiving space along its entire extension relative to the circumferential direction of the locking element have a radial extent which is greater than the radial extent of the receiving space. In such an embodiment, the press wings over their entire extension relative to the circumferential direction of the locking element to an excess, so that they lie flat along their entire extension of the outer sleeve and on the inner sleeve and are pressed together.

Alternatively, it can be provided that the press vanes have a plurality of radial elevations spaced apart from one another in the circumferential direction of the locking element and have a radial extent greater than that in the region of the radial elevations before being pressed into the receiving space extending between the inner sleeve and the outer sleeve radial extent of the receiving space. In such an embodiment of the invention, the press wings in the region of their radially outwardly and / or radially inwardly directed elevations an excess and are pressed together during insertion into the receiving space in the region of these elevations. This facilitates the insertion of the squeeze wings in the receiving space, wherein they are in the area when inserted into the receiving space can bend elastically or plastically between the elevations in order to increase the pressing force acting on the inner sleeve and the outer sleeve.

In a preferred embodiment of the invention, the inner sleeve contacted in the inserted state, the outer sleeve only in at least one extending in the circumferential direction of the inner sleeve bearing portion of the outer sleeve and the inner sleeve is acted upon by the locking element with an axial tensile force in the direction of the outer sleeve, wherein the insulating part with an in axial direction over the free end of the inner sleeve projecting abutment surface bears against the outer sleeve. In such an embodiment of the invention, the inner sleeve is in the inserted state only in at least one contact area extending in the circumferential direction of the inner sleeve, electrically connected to the outer sleeve, an electrical contact on the front side of the inner sleeve is avoided, however, by the insulating part on the free End of the inner sleeve protrudes and forms a stop surface, which rests in the inserted state of the inner sleeve on the outer sleeve. The front end region of the insulating part in the insertion direction thus forms a spacer element which, in the inserted state of the inner sleeve, ensures a spacing between the free end of the inner sleeve and the outer sleeve. In order to avoid an axial movement of the inner sleeve relative to the outer sleeve, the inner sleeve is acted upon by the locking element with an axial tensile force in the direction of the outer sleeve. The tensile force ensures that the over the free end of the inner sleeve projecting end of the insulating member maintains its position on the outer sleeve, the insulating part is thus pressed by the locking element against the outer sleeve. When inserting the inner sleeve into the outer sleeve, the outer sleeve forms a stop, for example, with a bottom wall to which abuts the projecting beyond the free end of the inner sleeve abutment surface of the insulating before the free end of the inner sleeve can contact the bottom wall of the outer sleeve in the axial direction.

It is advantageous if the insulating part rests against the inner sleeve with a rear abutment surface remote from the outer sleeve, preferably at an inner end. shoulder of the inner sleeve. In such an embodiment, the insulating part is clamped under the action of the axial tensile force of the locking element between the inner sleeve and the outer sleeve. This increases the mechanical strength of the coaxial connector assembly and avoids axial movement of the inner sleeve relative to the outer sleeve.

It is particularly advantageous if the inner sleeve in the inserted state electrically contacts the outer sleeve only in a single contact region, wherein the contact region is arranged on an inner side of the outer sleeve and surrounds the inner sleeve in the circumferential direction. Such a configuration is characterized by a particularly low passive intermodulation, because unintentional relative movements of the inner sleeve relative to the outer sleeve in the axial direction or in the circumferential direction result in such a configuration at best very little impairment of the electrical transmission quality of the coaxial connector assembly.

The contact region of the outer sleeve extending along the circumference of the inner sleeve is expediently configured as a cylindrical wall section of the outer sleeve.

On the cylindrical wall portion of the outer sleeve joins in an advantageous embodiment of the invention in a direction towards the free end of the outer sleeve conically expanding wall portion of the outer sleeve into which the inner sleeve dips, wherein the flared wall portion and the inner sleeve between them an annulus define.

At the conically widening wall portion of the outer sleeve can connect in the direction of the free end of the outer sleeve, a cylindrical wall portion.

The outer sleeve is rigidly formed in an advantageous embodiment of the invention, so that it can not be practically deformed in the radial and axial directions. It can be provided that the outer sleeve is integrally connected to a housing wall of an electrical assembly. Via a passage opening of the housing wall, a first contact pin can be inserted into the outer sleeve connected in one piece with the housing wall, the first contact pin being electrically connected to a second contact pin after insertion of the inner sleeve into the outer sleeve via the inner conductor part.

The locking element has in a preferred embodiment of the invention, an electrically non-conductive spacer, which is inserted between a first contact pin remote from the end portion of the outer sleeve and in the inserted state of this end portion in the circumferential direction region of the inner sleeve. The spacer ensures that the end portion of the outer sleeve facing away from the first contact pin can not inadvertently electrically contact the region of the inner sleeve surrounded by this end portion.

It is particularly advantageous if the spacer can be pressed in between the end section of the outer sleeve facing away from the first contact pin and the region of the inner sleeve surrounded by this end section. The spacer in such an embodiment not only has the function of ensuring a distance between the end portion of the outer sleeve facing away from the first contact pin and the area of the inner sleeve which is surrounded by this end portion, but the spacer also has the function of a clamping member having a mechanically loadable Ensures connection between the outer sleeve and the inner sleeve.

In a particularly preferred embodiment of the invention, the locking element has an annular space into which the outer sleeve with an end portion facing away from the first contact pin is insertable. The end portion of the outer sleeve facing away from the first contact pin thus assumes a position in the annular space of the locking element in the end position of the locking element. The locking element extends in such a Embodiment both on the inside and the outside of the end portion of the outer sleeve facing away from the first contact pin and on the end face thereof.

Preferably, the end portion of the outer sleeve facing away from the first contact pin can be pressed into the annular space.

The locking element is advantageously made of an electrically non-conductive material.

As already mentioned, the electrical transmission quality of coaxial connector assemblies can be affected by unintentional movements of the inner sleeve relative to the outer sleeve. In order to keep such impairments particularly low, in an advantageous embodiment of the invention, the coaxial connector arrangement has a spring element which can be clamped in the axial direction between mutually facing support surfaces of the inner sleeve and the outer sleeve. The spring element is compressed when inserting the inner sleeve in the outer sleeve in the axial direction and thus counteracts the aligned in the axial direction holding force of the locking element. The interaction of the locking element and the spring element ensures that the extent of unintentional micromotion of the inner sleeve relative to the outer sleeve can be kept particularly low. The spring element counteracts axial micro-movements of the inner sleeve and causes a tolerance compensation, the manufacturing tolerances of the inner sleeve, the outer sleeve and the locking element compensates.

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

The spring element is advantageously supported on radially oriented steps of the inner sleeve and the outer sleeve. For example, it may be provided that the inner sleeve carries a circumferentially extending annular groove in which the spring element is arranged, wherein the spring element protrudes in the radial direction of the annular groove and abuts in its protruding portion at a stage of the outer sleeve, on which the inner wall the outer sleeve extended in the radial direction.

It can also be provided that the spring element is supported on the one hand on a shoulder of the inner sleeve and on the other hand on a radially oriented step of the outer sleeve.

Preferably, the spring element surrounds the inner sleeve in the circumferential direction.

It is particularly advantageous if the spring element is designed as an annular elastomer part. In such an embodiment, the spring element is made of an elastomeric material, which ensures an elastic deformation of the spring element in a structurally simple manner. The elastomeric part is designed in the manner of a ring and can occupy a position between a support surface of the outer sleeve and a support surface of the inner sleeve when inserting the inner sleeve in the outer sleeve.

It is particularly advantageous if an annular space extending between the inner sleeve and the outer sleeve can be sealed by means of the 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 the extending between the inner sleeve and the outer sleeve annulus. The spring element is formed in a preferred embodiment of the invention as an O-ring or in the form of a sealing sleeve. The sealing sleeve forms a cylinder jacket, which surrounds the inner sleeve in the circumferential direction and is supported for example on a shoulder of the inner sleeve and on a step of the outer sleeve.

At the fifth stage 98, a second circular cylindrical wall portion 100 of the outer sleeve 12 connects. The second circular-cylindrical wall section 100 extends up to the end face 90 of the outer sleeve 12.

In addition to the outer sleeve 12 and the inner sleeve 26, the coaxial connector assembly 10 has a locking element 102 which defines the inner sleeve 26 in the outer sleeve 12. The locking element 102 is made of an electrically non-conductive material. In particular, it can be provided that the locking element 102 is made of the same electrically non-conductive material as the insulating part 70. For the production of the locking element 102, for example, a polytetrafluoroethylene material can be used.

The locking element 102 is designed in the manner of a sleeve, which is designed double-walled relative to the longitudinal axis 78 of the coaxial connector arrangement 10 at the level of an end section 104 of the outer sleeve 12 which is adjacent to the end face 90. At the level of the end portion 104, the locking element 102 has a locking collar 106, which is formed by a plurality of press wings uniformly distributed over the circumference of the inner sleeve 26, of which a press wing 108 is shown in FIG. The press wings 108 are designed in the manner of spring tongues and carry at their free end in each case a radially inwardly directed latching projection 110, which engages behind the second step 36 of the second inner sleeve section 34. The press wings 108 can be pressed in between the end section 104 of the outer sleeve 12 and the second inner sleeve section 34 of the inner sleeve 26.

Between two adjacent pressing wings 108, the locking element 102 in each case one of the end face 90 of the outer sleeve 12 facing away latching wing 112 which engages behind the first stage 32, via which the first inner sleeve section 30 merges into the second inner sleeve section 34. The latching wings 112 are also formed in the manner of spring tongues. The locking collar 106 is surrounded by a jacket 114 of the locking element 102. The jacket 114, in combination with the locking collar 106, defines an annular space 116 into which the end portion 104 of the outer sleeve 12 facing away from the first contact pin 25 is inserted. The jacket 114 extends up to the level of the radially outwardly directed fourth step 86 of the outer sleeve 12, wherein it engages behind the fourth stage 86 by means of locking lugs 118. The detents 118 are also configured in the manner of spring tongues. They are distributed over the circumference of the inner sleeve 26 and each separated by longitudinal slots 120 of the shell 114 from each other. The longitudinal slots 120 extend in the axial direction to a longitudinally central region of the jacket 114. By the use of the locking lugs 118 and by the use of the presser wings 108 and the locking wings 112, the locking element 102 is elastically deformable in the radial direction.

The locking element 102 can optionally be pre-assembled on the inner sleeve 26 or on the outer sleeve 12. This will be explained in more detail below with reference to Figures 5 and 6. Subsequently, the locking element 102 can be pushed onto the outer sleeve 12 or onto the inner sleeve 26 when the inner sleeve 26 is inserted into the outer sleeve 12. In its end position, the locking element 102 can be locked both with the inner sleeve 26 and with the outer sleeve 12, the end portion 104 can be pressed into the annular space 116 and the press wings 108 can be pressed between the inner sleeve 26 and the outer sleeve 12 so that means the locking element 102 a resilient and releasable mechanical connection between the inner sleeve 26 and the outer sleeve 12 can be achieved for fixing the inner sleeve 26 relative to the outer sleeve 12th

In order to counteract manufacturing tolerances of the outer sleeve 12, the inner sleeve 26 and the locking element 102, which could lead to the inner sleeve 26 still being able to carry out micro movements relative to the outer sleeve 12 despite the use of the locking element 102, the coaxial Connector assembly 10, a spring element in the form of an O-ring 122 which is disposed in the annular groove 28, wherein it protrudes in the radial direction of the annular groove 38. The O-ring 122 is made of an elastomeric material and is based on the one hand on the annular groove 38 bounding third stage 40 of the inner sleeve 26 and on the other hand on the between the conical wall portion 26 and the second circular cylindrical wall portion 100 fifth step 98 of the outer sleeve 12 from , The O-ring 122 is elastically deformable and is compressed in the axial direction when the locking element 102 assumes its end position.

By means of the O-ring 122 micro-movements of the inner sleeve 26 can be kept very small relative to the outer sleeve 12. In addition, the O-ring 122 forms a sealing element, with the penetration of moisture into the outer sleeve 12 can be prevented as well as the ingress of dirt particles. An annular space 124 extending between the third inner sleeve section 46 and the conical wall section 96 can be sealed in a splash-water-proof and dust-tight manner by means of the O-ring 122.

As already mentioned, the locking element 102 can be preassembled by the user optionally on the inner sleeve 26 or also on the outer sleeve 12. FIG. 5 illustrates a situation in which the locking element 102 has been pushed onto and pressed onto the inner sleeve 26 in such a way that the rearward locking wings 112 engage behind the first step 32 and the pressing wings 108 engage behind the second step 36, so that the Locking element 102 for pre-assembly with the inner sleeve 26 latched and axially immovable and rotationally fixed to the inner sleeve 26 is held. In a further assembly step, the O-ring 122 is inserted into the annular groove 38. The preassembled structural unit in the form of the inner sleeve 26, the locking element 102 and the O-ring 122 can then be connected to the outer sleeve 12. The inner sleeve 26 is in this case inserted so far into the outer sleeve 12, that the front abutment surface 74 comes to rest on the bottom wall 76 and the second annular bead 58 abuts the abutment region 94. Simultaneously, the locking element 102 in the axial direction so far on the outer sleeve 12th pushed and pressed that the locking lugs 118 engage behind the fourth stage 86 of the outer sleeve 12. The inner sleeve 26 is in this case acted upon by the locking element 102 with a force in the direction of the outer sleeve 12, so that the O-ring 122 is slightly elastically deformed and the insulating member 60 between the bottom wall 76 of the outer sleeve 12 and the inner shoulder 56 of the inner sleeve 26 is clamped ,

Alternatively, the user also has the option of setting the locking element 102 for preassembly on the outer sleeve 12. This is shown in FIG. In this case, the locking element 102 can be pushed and pressed onto the outer sleeve 12 by the user in the axial direction so far that the latching lugs 118 engage behind the fourth step 86 and the end section 104 dips into the annular space 116. The preassembled on the outer sleeve 12 locking element 102 can then be pushed so far when inserting the inner sleeve 26 in the outer sleeve 12 on the inner sleeve 26 and pressed that the locking wings 112, the inner sleeve 26 engage behind the first stage 32 and the press wing 108 between the end portion 104 of the outer sleeve 12 and the second inner sleeve portion 34 are pressed and the inner sleeve 26 engage behind the second stage 36. Thus, when inserting the inner sleeve 26 into the outer sleeve 12, a rotationally fixed and axially immovable locking connection between the locking element 102 and the inner sleeve 26 is achieved, so that the inner sleeve 26 is fixed by means of the locking element 102 in the outer sleeve 12.

In the figures 7 and 8, a second advantageous embodiment of a coaxial connector assembly according to the invention is shown, which is generally designated by the reference numeral 130. The coaxial plug connector arrangement 130 is largely identical in construction to the coaxial plug connector arrangement 10 described above with reference to FIGS. 1 to 6. For identical components, therefore, the same reference numerals are used in FIGS. 7 and 8 as in FIGS 6 and with respect to these components, reference is made to the above explanations to avoid repetition. The coaxial connector assembly 130 differs from the coaxial connector assembly 10 in that the second inner sleeve portion 34 has a constant outer diameter over its entire length with respect to the longitudinal axis 78. Thus, the second stage 36 is omitted in the case of the coaxial connector arrangement 130. Accordingly, the locking collar 106 of the locking element 102 of the coaxial connector arrangement 130 has no latching projections 110. When the locking element 102 is pushed onto the second inner sleeve section 34, the locking collar 106 is radially widened in the case of the coaxial connector arrangement 130, that is to say the locking collar 106 is pressed onto the second inner sleeve section 34. When it is pressed onto the second inner sleeve section 34, the locking element 102 reaches its end position in that the latching wings 112 engage behind the first step 32, as has already been explained above with reference to the coaxial connector arrangement 10.

Another difference between the coaxial connector assembly 130 and the coaxial connector assembly 10 is the design of the spring member. While an O-ring 122 is used in the coaxial connector assembly 10, in the case of the coaxial connector assembly 130 a sealing sleeve 132 is used, which is made of an elastomeric material and on the one hand on an annular shoulder 134 of the inner sleeve 26 and on the other a fifth step 98 of the outer sleeve 12 is supported. The sealing sleeve 132 forms in a similar manner as the above-described in detail O-ring 122 a spring and sealing element, which counteracts any micro-movements of the inner sleeve 26 and beyond the penetration of moisture and dirt particles in the outer sleeve 12 is prevented.

Also in the coaxial connector assembly 130, the user has the ability to pre-assemble the locking member 102 selectively on the inner sleeve 26 or on the outer sleeve 12. If the locking element 102 is initially applied to the second inner sleeve section 34 of the inner sleeve 26 pushed, wherein the locking element 102 is extended in the radial direction, the locking element 102 can then be pushed so far onto the outer sleeve 12 during insertion of the inner sleeve 26 in the outer sleeve 12 until the locking lugs 118 engage behind the fourth stage 86 of the outer sleeve 12. However, the user also has the option of first pushing the locking element 102 onto the outer sleeve 12 for preassembly, and then the locking element 102 can be slid so far into the outer sleeve 12 on the second inner sleeve section 34 of the inner sleeve 26 when the inner sleeve 26 is inserted into the outer sleeve 12. until the latching wings 112 of the locking element 102 engage behind the first step 32 of the inner sleeve 26.

Also in the case of the coaxial plug connector arrangement 130 shown schematically in FIGS. 7 and 8, the inner sleeve 26 is fixed in the outer sleeve 12 with the aid of the locking element 102 and any micromotion of the inner sleeve 26 is counteracted by the use of the sealing sleeve 132.

FIGS. 9 and 10 schematically show a third advantageous embodiment of a coaxial plug connector arrangement according to the invention, which is designated overall by the reference numeral 150. The coaxial connector assembly 150 is designed substantially identical to the coaxial connector assembly 130 described above with reference to FIGS. 7 and 8. For identical components, therefore, the same reference numerals are used in FIGS. 8 and 9 as in FIGS 8 and with respect to these components, reference is made to the above explanations to avoid repetition.

The coaxial connector assembly 150 differs from the coaxial connector assembly 130 on the one hand in that instead of the sealing sleeve 132, which is clamped only in the axial direction between two mutually facing support surfaces of the inner sleeve 26 and the outer sleeve 12, a sealing sleeve 152 is used both in the axial direction and in radial Direction between facing support surfaces of the inner sleeve 26 and the outer sleeve 12 is clamped. In the axial direction, the sealing sleeve 152 is clamped in a similar manner as the sealing sleeve 132 of the embodiment shown in Figures 7 and 8 between the fifth stage 98 of the outer sleeve 12 and the annular shoulder 134 of the inner sleeve 26, and in the radial direction, the sealing sleeve 52 between a clamped in the direction of the end face 90 to the fifth step 98 subsequent cylindrical wall portion 154 of the outer sleeve 12 and in the direction of the annular bead 54 adjoining the annular shoulder 134 conical wall portion 156 of the inner sleeve 26. The conical wall section 156 is in this case formed by the spring tongues 50 of the inner sleeve 26. The sealing sleeve 152 forms a spring element, which counteracts any micro-movements of the inner sleeve 26 relative to the outer sleeve 12 and moreover causes a reliable seal, so that liquid and dirt particles can not penetrate into the annular space 124 and consequently not in the investment area, in which the annular bead 52 rests against the circular cylindrical wall section 94 of the outer sleeve 12.

Of the coaxial connector assembly 130 shown schematically in FIGS. 7 and 8, the coaxial connector assembly 150 shown schematically in FIGS. 9 and 10 also differs in that the locking member 102 has three press wings 158 uniformly distributed around the circumference of the locking member 102 has, prior to insertion of the inner sleeve 26 in the outer sleeve 12 have a radial extent which is greater than the extent of extending between the end portion 104 of the outer sleeve 12 and the second inner sleeve portion 34 receiving space 160 into which the press wings 158 can be pressed , The press vanes 158 have an oversize, which is illustrated in FIG. 10 and which, in the embodiment shown schematically in FIGS. 9 and 10, extends over the complete outside 164 and over the entire inside 166 of the press vanes 158. The press wings 158 are thus after the insertion of the inner sleeve 26 in the outer sleeve 12 with its outer side 164 flat on the inside of the end portion 104 of Outer sleeve 12, and with its inner side 166 are the press wings 158 after insertion of the inner sleeve 26 in the outer sleeve 12 flat on the outside of the inner sleeve portion 34 at. The press wings 158 are in this case plastically or preferably elastically compressed and thereby exert on the inner sleeve 26 and the outer sleeve 12 a considerable holding force, so that the inner sleeve 12 can perform virtually no micro-movements relative to the outer sleeve 12.

Also in the coaxial connector assembly 150, the user has the option of preassembling the locking member 102 either on the inner sleeve 26 or on the outer sleeve 12. In this regard, reference is made to the foregoing explanations of the coaxial connector assembly 130 to avoid repetition.

FIGS. 11 and 12 schematically show a fourth advantageous embodiment of a coaxial connector arrangement according to the invention, which is generally designated by the reference numeral 180. The coaxial connector assembly 180 is designed substantially identical to the coaxial connector assembly 150 described above with reference to FIGS. 9 and 10. For identical components, therefore, the same reference numerals are used in FIGS. 11 and 12 as in FIGS 10 and with respect to these components, reference is made to the above explanations to avoid repetition.

The coaxial connector assembly 180 differs from the coaxial connector assembly 150 in that it employs presser vanes 182 that are oversized only in the region of radially aligned protrusions. For this purpose, the pressing vanes 182 have on their outer side 184 two spaced-apart, radially outwardly facing outer elevations 186, 188, and on their inner side 190, the pressing vanes 182 each have a radially inwardly directed inner elevation 192. Relative to the circumferential direction of the locking element 102, the inner elevation 192 of each squeeze blade 182 is centered between the outer bumps 186 and 188 arranged. In the area between the outer and inner elevations 186, 188 and 192, the presser vanes 182 of the coaxial connector assembly 180 have no excess, but in the area between the outer elevations 186, 188 and the inner elevation 192, the radial extent of the press vanes 182 at most the same size as the radial extent of the receiving space 160, in which the press wings 182 can be pressed. In the region of the outer elevations 186, 188 and in the region of the inner elevation 192, however, the radial extent of the presser vanes 182 before being pressed into the receiving space 160 is greater than the radial extent of the receiving space 160, so that the presser vanes 182 in the region of the outer elevation 186 , 188 and the inner projection 192 when inserted into the receiving space 160 are compressed. In addition, the press wings 182 are bent when inserted into the receiving space 160 in the area between the outer elevations 186, 188 and the inner elevation 192. This becomes clear in particular from FIG. 12. The oversize present only in the region of the outer and inner elevations 186, 188, 192 facilitates the pressing of the presser vanes 182 into the receiving space 160, and the bending of the press vanes 192 in the area between the outer elevations 186, 188 and the inner elevation 192 ensures in combination with the compression of the elevations 186, 188 and 192 a reliable fixation of the inner sleeve 26 in the outer sleeve 12th

FIGS. 13 and 14 schematically show a fifth advantageous embodiment of a coaxial connector arrangement according to the invention, which is generally designated by the reference numeral 210. The coaxial connector assembly 210 is similarly configured as the coaxial connector assembly 150 described above with reference to FIGS. 9 and 10. For identical components, therefore, the same reference numerals are used in FIGS. 13 and 14 as in FIGS. 9 and 10 and with respect to these components, reference is made to the foregoing explanations to avoid repetition. The coaxial connector assembly 210 differs from the coaxial connector assembly 150 by a locking member 212 which, unlike the locking member 102 discussed above, does not have a skirt surrounding the outer sleeve in the circumferential direction. Rather, the locking element 212 has three circumferentially uniformly spaced pressing wings 214, which can be pressed in a similar manner as the above-described with reference to Figures 9 and 10 press wings 158 between the inner sleeve 26 and the outer sleeve 12 and this before the Press in an oversize. In addition, the locking element 212 has three first latching wings 216, which cooperate with latching elements in the form of an internally formed in the end portion 104 of the outer sleeve 12 locking groove 218 to achieve a latching connection. The latching groove 218 has a groove wall 220 oriented perpendicular to the longitudinal axis 78 of the coaxial plug connector arrangement 210, which forms a holding surface and is engaged behind by a latching hook 222 of the latching blade 226. In the circumferential direction of the locking element 212, the pressing vanes 214 and the first latching vanes 216 alternate, so that in the circumferential direction in each case one latching leaf 216 follows a pressing wing 214. This becomes clear in particular from FIG. By means of the first latching wings 216, a latching connection between the latching element 212 and the outer sleeve 12 of the coaxial plug connector arrangement 210 can thus be produced. In addition, a locking connection between the locking element 212 and the inner sleeve 26 of the coaxial connector assembly 210 can be made. For this purpose, the locking element 212 has three uniformly distributed over the circumference of the locking element 212 second locking wings 224 which cooperate with a locking element of the inner sleeve 26 in the sense of a latching connection. The locking element forms a first annular collar 226, which extends in an outer sleeve 12 facing away from the end portion 228 over the circumference of the inner sleeve 26. The second latching wings 224 each form a latching recess 230, which receive the first annular collar 226, wherein the second latching wings 224 engage behind a rear side 232 of the first annular collar 226 facing away from the outer sleeve 12. The back 232 thus forms as well as the groove wall 220 of the locking groove 218 a perpendicular to Longitudinal axis 78 of the coaxial connector assembly 210 aligned holding surface, which is engaged behind by the locking element 212.

The coaxial connector assembly 210 is characterized by a particularly compact design, wherein the locking element 12 engages the outer sleeve 12 on the inside and the inner sleeve 26 on the outside and thereby acts on the inner sleeve 26 with a force in the direction of the outer sleeve 12. In addition, any micro-movements of the inner sleeve 26 are counteracted by the press wings 240.

In a similar manner as in the case of the coaxial connector assembly 150 described above with reference to FIGS. 9 and 10, a sealing sleeve 234 is also used in the coaxial connector assembly 210, which is located between the inner sleeve 26 and in the axial direction both in the radial direction and in the axial direction Outer sleeve 12 is clamped. The sealing sleeve 234 is in this case clamped in the axial direction on the one hand on an inside step 236 of the outer sleeve 12 of the coaxial connector assembly 10 and on the other hand on an end face 238 of a spaced apart from the first annular collar 226 second annular collar 240. In the radial direction, the sealing sleeve 234 between a circular cylindrical wall portion 242 of the outer sleeve 12 and in the direction of the second annular bead 52 adjoining the second annular collar 240 wall portion 244 of the inner sleeve 26 of the coaxial connector assembly 210 is clamped. The sealing sleeve 234 also counteracts any micro-movements of the inner sleeve 26 and also prevents the penetration of liquid and dirt particles in the area in which the annular bead 52 of the inner sleeve 26 rests against the first circular-cylindrical wall portion 92 of the outer sleeve 12.
