The invention relates to an electrical connector according to the preamble of patent claim 1 and a connector assembly with an inventive electrical plug connector ^¬ and an associated mating connector. Furthermore, the invention relates to a use of Steckverbinderano ^¬ rdnung for electrical connection of two circuit boards. For the electrical connection of adjacent and parallel ^¬ directed printed circuit boards connectors are used, which fastened to opposite surfaces of the guide plates who ^¬ . Such connectors referred to as B2B (board-to-board) connectors consist of three connector parts, namely two sockets each secured to the printed circuit board and one

Adapter (also referred to as bullet), which is formed at the two ends in each case as a plug. With such an adapter, a lateral axis offset with respect to the longitudinal axes of the two sockets can be compensated for by allowing the adapter to be tilted, thereby making contact with the two sockets possible again. The disadvantage of such B2B connectors is their three-part view.

The invention has for its object to provide an improved connector of the type mentioned, with wel ^¬ chem a B2B connector is produced. Another object is to provide a connector assembly with this electrical connector, with which a B2B connection can be realized.

The first object is achieved by an electrical connector having the features of patent claim 1. Such an electrical connector with

a sleeve formed outer conductor,

- an inner conductor, and

- one designed as a cylindrical Dielektrikumskörper dielectric having an internal bore for receiving the Innenlei ^¬ ters,

- The sleeve is formed with an axial holding portion and an axial compensation portion, which are connected via an axial bending portion,

- the bending portion a extending in a circumferential line of the sleeve slot having at least said nichtge ^¬ slit region is formed as the holding portion with the Ausgleichsab ^¬ cut connecting the connecting web, and - the Dielektrikumskörper a arranged in the holding portion first Dielektrikumsteilkörper and arranged in Verbindungsab cut ^¬ having second dielectric sub-body, wherein the dielectric sub- ^{bodies are} arranged in the sleeve spaced ^¬ on.

With such an inventive electrical Termina ^¬ which implements a B2B connector together with a mating connector, the tegriert the lateral axis offset compensating tolerance compensation in the electrical Plug connector by means of a flexible bending portion of the sleeve in ^¬. By means of this flexible bending section, the equalizing section relative to the holding portion, which is preferably connected to a circuit board prior ^¬ be pivoted from the Rich ^¬ tung the longitudinal axis of the sleeve of the connector. This eliminates a known from the prior art adapter, so that only two components are required to implement a B2B connector. This makes it possible to automate the assembly process and the connection of the circuit boards, since the two components of the B2B connector according to the invention can be designed as SMD components.

It will be noted for clarification of terminology that a circumferential line of a sleeve is a line whose points tensystem in the description of the electrical plug ^¬ connector and / or the sleeve in a cylindrical coordinate in which the axial direction of axis defining by the plug-in direction of the electrical connector is given before ^¬ all have the same coordinate on this axis, so that the circumferential line in a plane which is perpendicular ^¬ right to the direction of insertion, is located.

In one embodiment of the invention, at least two slots are arranged one behind the other in the circumferential direction of the sleeve, wherein preferably in the axial direction of the bending portion is formed with at least two slots which are arranged offset from one another. Making it possible to achieve, with which an axial offset can be compensated with productive ^¬ tion usual values a sufficient bending radius.

According to a particularly preferred embodiment of the invention, the connecting web is formed with an axial width corresponding to the width of the slot. Such a slot has an axial width, so that the opposite end faces of the holding portion and the compensating portion are spaced and therefore also the connecting web an axial width of the slot corresponding axial length have ^¬ , whereby the required bending elasticity in the region of the bending section is ensured. A further advantageous development of the invention provides that the inner conductor in the transition region of the first and second lektrikumsteilkörpers The ^¬ Dielektrikumsteilkörpers has a cross-sectional taper. This also the inner conductor is given that he ^¬ ford variable bending elasticity in the range of the bending portion of the sleeve.

A further improvement of the bending elasticity in the region of the bending section is ensured by the fact that the diameter of the inner conductor is formed in the region of the second dielectric ^{¬ part} body with a smaller diameter compared to the diameter of the inner bore of the second dielectric ^{¬ part} body. In order to ensure the dielectric of the Dielektrikumseigenschaft OF INVENTION ^¬ to the invention connector, comprises in a further embodiment of the invention the adjacent end faces of the first and second Dielektrikumsteilkörpers a blind bore and the other end side of the arrival thereto matched contour.

Another advantageous embodiment of the invention provides that the connecting web, starting from the holding section or the compensating section, is extended by means of cutouts into the compensating section or the holding section, wherein the free cuts are preferably arranged running parallel in the axial direction. With such cutouts ei ^¬ ne sufficient length of the connecting web or the webs Verbin ^¬ dung for realizing the required Biegeelastizi- ty is ensured in the region of the bending portion.

A further improvement in the bending elasticity in the region of the bending section is achieved by further development, that the connecting web has an inwardly pointing and extending in the circumferential direction bead.

With such a bead in the connecting web of the second partial dielectric body is formed with a duri ^¬ fenden in the axial direction groove, which is congruent with the connecting web for receiving the bead and therefore designed with a depth of at least the height of the bead on the inner wall of the sleeve corresponding depth , Preferably, the Si ^¬ bridge is formed as a triangular bead. In order for a Längenaus is equal effected using this Si ckenartigen connecting webs during pivoting of the off ^¬ same section relative to the holding portion. According to a further preferred embodiment of the invention, the holding portion of the sleeve is formed on a bending portion opposite the end face with a connecting flange for mechanical and electrical connection to a ^{Leiterplat ¬} te. Thus, the sleeve of the connector according to the invention can be used as an SMD component.

According to the invention, it is provided that the Ausgleichsab ^{¬ section of} the sleeve with a bending section gegenüberlie ^¬ ing end face is formed with a contact zone for electrical contacting with a mating connector.

Here, preferably, the contact zone of the compensating portion before ^¬ a circumferential bead, the bead base is configured for making contact with an outer conductor of a mating connector. The second dielectric body part is preferably shortened by the axial length of the contact zone so that the sleeve can receive the contact zone of a mating connector in the region of the contact zone as a socket. The second-mentioned object is achieved by an electrical connector assembly having the features of claim 17. Such an electrical connector assembly with a ^¬ he inventive electrical connector and a mating connector ^¬ is characterized according to the invention is characterized in that the mating connector comprising:

Connector assembly of a connector ge ^¬ according to Figure 9 and a mating connector according to Figure 10. Figures 1 and 2 show an electrical connector 1.1, which together with an associated Gegensteckverbin ^¬ of 1.2 according to Figures 5 and 6, a connector assembly 1 as a B2B connector two circuit boards 10 and 11 electrically interconnected (see Figure 7). For this purpose, according to Figure 7, the electrical connector 1.1 mechanically and electrically connected via a connection ^¬ flange 2.10 mechanically and electrically to the circuit board 10 and the mating connector 1.2 via a connecting flange 1.23 with the other circuit board 11.

This connector assembly 1 has the property that with a lateral displacement or angular displacement of the mechanically connected to the printed circuit boards 10 and 11. Plug connector 1.1 and 1.2 with respect to their axes of symmetry Al and A2 (see FIG. 8), a tolerance compensation of this offset of ^¬ means of the electrical connector 1.1 is enabled. Ge ^¬ genüber the connector assembly 1 according to FIG 7, in wel ^¬ cher the two axes of symmetry Al and A2 th curse each other, the connector assembly 1 of Figure 8 to an angular displacement of the size s. This angular offset s, ie a tilting of the two connectors 1.1 and 1.2 zueinan ^¬ , is offset by means of a bending section 2.3 and a bending ^¬ zone of the electrical connector 2.1 of the connector assembly 1. These compensation or tolerance radio ^¬ tion of the electrical connector 1.1 is hereinafter he explained ^¬.

According to Figures 1 and 2, the electric components of 1.1 a sleeve 2 comprises as an outer conductor 2.0, an inner conductor pin 3 as the inner conductor 3.0 as well as a space between the inner conductor 3.0 and the outer conductor 2.0 filling Dielekt ^¬ rikum 4.0, which as a cylindrical Dielektrikumskörper 4 2-part of a first dielectric part body 4.1 and ei ^¬ nem second dielectric sub-body 4.2 is constructed.

The sleeve 2 of the electrical connector 1.1 consists of three axial sections, namely an axial holding section 2.1 and an axial compensating section 2.2, which are mechanically connected via the already mentioned above axial bending section 2.3. At the free end face of the holding section 2.1, a connecting flange 2.10 is formed by the edge region of this end face is funnel-shaped aufwei ^¬ tet and thereby a contact surface for abutment against the Lei ^¬ terplatte 10 and for mechanical connection with the same arises. Further, this connecting flange is provided with Radi ^¬ alschlitzen 2.11 2.10. On the opposite end face of the sleeve 2 of the compensating section 2.2 ends in a contact zone 20.2 for electrically contacting the external conductors ^¬ ters 2.0 or of the inner conductor 3.0 with an outer conductor 1210 and an inner conductor 1240 of the mating connector 1.2 (see FIG. 7).

In the region of the bending section 2.3, two circumferentially adjacent circumferential lines LI and L2 run in the axial direction. Is suggested as already by the term "circumferential line", the axial ^¬ coordinate of all points is always the same at a given circumferential line, the circumferential lines LI and L2 are thus in each case in an unillustrated plane on which the axial direction is perpendicular.

On the circumferential line LI two slots 5.1 and 5.2 are arranged, between which each unslotted areas lie on the circumferential line LI and each form a ring segment-like connecting web 5.0. On the other circumferential line L2 are also two slots 6.1 and 6.2 with between these slits 6.1 and 6.2 lying on the circumferential line L2 unslit areas as a further ring segment-like Verbin ^¬ dung stege 6.0. The slits 6.1 and 6.2 lying on the circumferential line L2 are offset relative to one another with respect to the slits 5.1 and 5.2 lying on the circumferential line LI, so that the connecting webs 5.0 and 6.0 are not aligned axially with one another.

The distance a of the two circumferential lines LI and L2 is small compared to the axial length L of the electrical connector 1.1. The slots 5.1, 5.2, 6.1 and 6.2 have a width b, which may be, for example, in the order of mm. The axial length of the connecting webs 5.0 and 6.0 therefore correspond to the width b of the slots 5.1, 5.2, 6.1 and 6.2. The processed neighboring position of the two circumferential lines LI and L2 results in egg ^¬ ner forming an annular region 7 between Schlit ^¬ zen 5.1 and 5.2 on the circumferential line LI and the slits 6.1 and 6.2 on the circumferential line L2. The two portions of the sleeve 2, the holding section 2.1 and the compensation section 2.2 are connected via this annular region 7 as well as the one hand via the connecting webs 5.0 and on the other hand on the Ver ^¬ bond bridges 6.0.

With such a bending section 2.3 of the sleeve 2 is an overall steering like characteristic is achieved so that the Ausgleichsab ^¬ section 2.2 angled with respect to the holding section 2.1 who can ^¬. This elastic bending property is also to be ensured for the dielectric 4.0 and the inner conductor 3.0. The corresponding bending elasticity for the dielectric 4.0 is achieved in that the dielectric body 4 comprises two parts of a first dielectric arranged in the holding section 2.1. Partial body 4.1 and in the compensating section 2.2 ange ^¬ arranged second dielectric part body 4.2 is made.

These two dielectric part bodies 4.1 and 4.2 are spaced by means of a gap formed by adjacent end faces 4.11 and 4.21 4.3 arranged in the sleeve 2, wherein the gap 4.3, starting from the peripheral surface of the two Dielekt ^¬ rics part body 4.1 and 4.2 aligned with the annular portion 7 of the bending section 2.3 ,

The two end faces 4.11 and 4.21 of the two Dielektri ^¬ kumsteilkörper 4.1 and 4.2 are formed with matched contours. The front side 4.11 of the first Dielekt ^¬ rics Teilkörpers 4.1 has a central blind hole 4.12, to which the end face 4.21 with a zylinderförmi ^¬ gene extension 4.22, which dips into the blind hole 4.12, is adjusted. The diameter of the header 22.4 is smaller than the diameter of the blind bore 4.12 so that the gap 4.3 on the basis rikumsteilkörper 4.1 and 4.2 over a radial distance Zvi ^¬ rule of the circumferential surface of the two Dielekt- the extension 22.4 and the circumferential surface of the Sacklochboh ^¬ tion 12.04 maze-like to the inner conductor 3.0 continues.

The inner conductor 3.0 as inner conductor pin 3 is mounted in an inner bore 4.10 of the holding section 2.1 and a Innenboh ^¬ tion 4.20 of the compensation section 2.2, wherein Be ^¬ rich the groove bottom of the blind hole 4.12 on the front ^¬ page 4.11 of the holding section 2.1 of the inner conductor pin 3 egg ^¬ ne cross-sectional tapering 3.1 in the form of a circumferential groove 3.10 having a rectangular cross section, said groove 3.10 extends into the extension 4.22. In the region following the groove 3.10 in the direction of the compensation section 2.2, the inner conductor pin 3 has a diameter d, which is slightly smaller than the diameter D of the blind hole ^¬ 20.4 of the second Dielektrikumsteilkörpers 4.2.

With such a trained inner conductor pin 3, together with the 2-part dielectric body 4 and the Biegeab ^{¬ section} 2.3 of the sleeve 2 for a compensation of a latera ^¬ len axis offset with respect to the axes of symmetry AI and A2 of the electrical connector 1.1 and the Gegensteckverbin ^¬ DERS 1.2 required bending elasticity of the connector 1.1 reached.

The mating connector 1.2 used for the connector assembly 1 according to FIGS. 7 and 8 is shown in FIG. 6 and comprises a sleeve 1.21 as an outer conductor 1210, in which an inner conductor pin 1.24 as inner conductor ¹²⁴⁰ and a cylindrical dielectric body 1.26 as dielectric 1,260 is arranged.

The mating connector 1.2 has at one end a contact zone 1.22, which is formed by the sleeve 1.21 by means of an outwardly remote extension. At the other end of the Ge ^¬ gensteckverbinders 1.2 is from the sleeve 1.21 a connec ^¬ tion flange 1.23 in which the edge region of the sleeve 1.21 funnel-shaped to form a contact surface for abutment with the circuit board 11 and for mechanical connection with the ^¬ same expanded. Furthermore, this connecting flange is 1.23 provided with radial slots 1.230.

Between this connection flange 1.23 and the contact zone 1.22 is the dielectric body 1.26 with a In ^¬ nenbohrung 1.27 for receiving the inner conductor pin 1.24. The ^¬ ser inner conductor pin 24.1 has a slotted funnel shaped and listed at its projecting into the end contact zone 22.1 extended blind bore 1.25 for receiving the Innenleiterstif- tes 3 of the electrical connector 1.1.

The electrical connector 1.1 according to Figures 1 and 2 can also be performed with more than two slots 5.1 and 5.2 on a circumferential line LI. In addition, it is also possible to provide only one circumferential line LI or more than two circumferential lines instead of two circumferentially adjacent lines LI and L2 provided in the axial direction.

The plug connection between the electrical connector 1.1 and the mating connector 1.2 is carried out according to Figure 7 on the trained as a socket contact zone 2.20 of the plug connector ^¬ DERS 1.1 and formed as a plug contact zone 1.22 of the mating connector 1.2.

To achieve a resilient property are in this contact zone 2.20 axially extending slots 2.22 pre ^¬ see. The second partial dielectric body 4.2 ends before this contact zone 2.20, the inner conductor pin 3 projecting into this contact zone 2.20.

For electrically connecting the electrical connector 1.1 to the mating connector 1.2, the contact portion 1.22 of the mating connector 1.2 inserted from the contact zone 2.20 sleeve 2, so that the groove ^{¬ base of} the bead 2.21 on the peripheral surface of the contact zone 1.22 of the sleeve 1.21 under formation an electrical contact on ^¬ and simultaneously the end of the inner conductor pin 3 of electrical connector 1.1 is inserted into the blind bore 1.25 of the inner conductor pin 1.24 of the mating connector 1.2 to form an electrical contact, as can be seen from Figure 7.
