Description
Technical Field
The invention relates to an electrical plug connector according to the preamble of claim 1 and to a plug connector assembly with an electrical plug connector according to the invention and a dependent mating plug connector. Furthermore, the invention relates to the use of a plug connector assembly for electrically connecting two circuit boards.
Background
In order to electrically connect adjacent circuit boards which are oriented parallel to one another, plug connectors are used which are fastened to opposite sides of the circuit boards. This plug connector, which is referred to as a B2B (board-to-board) connector, is composed of three plug connectors, namely two sockets, each of which is fastened to a circuit board, and an adapter (also referred to as a plug connector), each of which is designed as a plug at both ends. By means of such an adapter, a lateral axial offset in relation to the longitudinal axes of the two sockets can be compensated for in that the adapter can be tilted and thus in turn brought into contact with the two sockets. A disadvantage of this B2B plug connector is its three-piece construction.
Disclosure of Invention
The invention is based on the object of providing an improved plug connector of the type mentioned at the outset, by means of which a B2B plug connection can be established. A further object is to provide a plug connector assembly with such an electrical plug connector, by means of which a B2B connection can be realized.
The first object is achieved by an electrical plug connector having the features of claim 1.
The electrical plug-in connector has
An outer conductor configured as a sleeve,
-an inner conductor, and
a dielectric, which is designed as a cylindrical dielectric body and has an inner bore for accommodating the inner conductor,
according to the invention, it is distinguished in that,
the sleeve is designed with an axial holding section and an axial compensating section, which are connected by an axial bending section,
the bending section has at least one slot running on the circumference of the sleeve, wherein the unslotted region is configured as a connecting bridge connecting the holding section to the compensating section, and
the dielectric body has a first dielectric part body arranged in the holding section and a second dielectric part body arranged in the connecting section, wherein the dielectric part bodies are arranged in the sleeve at a distance from one another.
With such an electrical plug connector according to the invention, which makes a B2B plug connection with a mating plug connector, tolerance compensation for transverse axial misalignment is incorporated into the electrical plug connector by means of the flexible bending sections of the sleeve. By means of the flexible bending section, the compensation section can be deflected out of the direction of the longitudinal axis of the sleeve of the plug connector relative to the retaining section, which is preferably connected to the circuit board. Thus, the adapter known from the prior art is omitted, so that only two components are required to implement the B2B plug connection.
This allows automation of the assembly process and the connection of the circuit board, since the two components of the B2B plug connection according to the invention can be designed as SMD components.
For the purpose of explaining the terms used, it should be pointed out here that the circumference of the sleeve is a line whose points all have the same coordinate on a cylindrical coordinate system (axis in which the axial direction is defined by the insertion direction of the electrical plug connector) when describing the electrical plug connector and/or the sleeve on this axis, so that the circumference lies in a plane perpendicular to the direction of extension.
In one refinement of the invention, at least two slots are arranged one after the other in the circumferential direction of the sleeve, wherein the curved section is preferably configured with at least two slots arranged offset from one another in the axial direction. In this way, a sufficient bending radius is achieved, by means of which the axial offset values that are usual in terms of production can be compensated.
According to a particularly preferred embodiment of the invention, the connecting bridge is configured with an axial length corresponding to the width of the slot. Such a slot has an axial width, so that the opposite end sides of the retaining section and the compensating section are spaced apart from one another, and therefore the connecting bridge also has an axial length corresponding to the axial width of the slot, thereby ensuring the desired bending resilience in the region of the bending section.
A further advantageous development of the invention provides that the inner conductor has a cross-sectional narrowing in the transition region of the first dielectric part body and the second dielectric part body. In this way, the inner conductor is provided with the required bending elasticity also in the region of the bent section of the jacket.
A further improvement of the bending elasticity in the region of the bending section is ensured in that the diameter of the inner conductor in the region of the second dielectric part body is configured to be smaller than the diameter of the inner bore of the second dielectric part body.
In order to ensure the dielectric properties of the dielectric of the plug connector according to the invention, according to a further embodiment of the invention one of the adjacent end faces of the first and second dielectric part bodies has a blind hole and the other end side has a contour which matches the blind hole.
A further advantageous embodiment of the invention provides that the connecting web extends from the holding section or the compensating section into the compensating section or the holding section by means of grooves, wherein the grooves are preferably arranged to run parallel in the axial direction. By means of such a groove, a sufficient length of the connecting bridge or connecting bridges is ensured to achieve the desired bending elasticity in the region of the bending section.
According to a further development, the bending elasticity in the region of the bending section is further improved in that the connecting webs have inwardly directed crimping portions which extend in the circumferential direction.
By means of such a bead in the connecting web, the second dielectric part is formed with a groove running in the axial direction, which runs exactly like the connecting web to accommodate the bead of the connecting web and is therefore embodied with a depth at least corresponding to the height of the bead on the inner wall of the sleeve. Preferably, the bead portion is configured as a triangular bead portion. As a result, when the compensating section is deflected relative to the holding section, a length compensation takes place via the bead-type connecting bridge.
According to a further preferred embodiment of the invention, the holding section of the sleeve is formed on the end side opposite the bending section with a connecting flange for mechanical and electrical connection to the circuit board. The sleeve of the plug connector according to the invention can thus be used as an SMD component.
According to a further development, it is provided that the compensation section of the sleeve is configured with an end face opposite the bending section, which end face has a contact region for electrical contact with a mating plug connector. The contact region of the compensation section preferably has a circumferential bead, the bottom of which is designed to establish contact with the outer conductor of the mating plug. Preferably, the second dielectric part body is configured such that the axial length of the contact section is shortened, so that the sleeve in the region of the contact section as a socket can accommodate the contact section of the mating plug connector.
The second object of the invention is achieved by an electrical plug connector assembly having the features of claim 17.
According to the invention, such an electrical plug connector assembly with an electrical plug connector according to the invention and a mating plug connector is distinguished in that the mating plug connector comprises:
an outer conductor, which is configured as a set and has a contact region for contacting an outer conductor of a plug connector and a connection flange for mechanical and electrical connection to a circuit board,
an inner conductor having a blind hole for receiving an inner conductor pin of an electrical plug connector,
a dielectric, which is designed as a cylindrical dielectric body and has an inner bore for receiving the inner conductor.
Such an electrical plug connector assembly is suitable for use as a B2B plug connector for connecting two circuit boards arranged in parallel, in which lateral axial misalignment between the electrical plug connector and the associated mating plug connector is compensated for by means of the bending sections of the plug connector according to the invention.

Detailed Description
Fig. 1 and 2 show an electrical plug connector 1.1 which, together with a subordinate mating plug connector 1.2 according to fig. 5 and 6, electrically connects two circuit boards 10 and 11 to one another as a B2B connector as a plug connector assembly 1 (see fig. 7). For this purpose, according to fig. 7, the electrical plug connector 1.1 is mechanically and electrically connected to the circuit board 10 via the connection flange 2.10 and the mating plug connector 1.2 is mechanically and electrically connected to the further circuit board 11 via the connection flange 1.23.
The plug connector assembly 1 has the property that, when the plug connectors 1.1 and 1.2, which mechanically connect the circuit boards 10 and 11, are laterally or angularly offset with respect to their axes of symmetry a1 and a2 (see fig. 8), tolerance compensation of this offset by means of the electrical plug connector 1.1 is achieved. With respect to the plug connector assembly 1 according to fig. 7, in which the two axes of symmetry a1 and a2 are aligned with one another, the plug connector assembly 1 according to fig. 8 has an angular offset of the size s. This angular offset s, i.e. the inclination of the two plug connectors 1.1 and 1.2 relative to one another, is compensated by means of the bent section 2.3 or bent section of the electrical plug connector 2.1 of the plug connector assembly 1. The compensation or tolerance function of the electrical plug connector 1.1 is explained below.
According to fig. 1 and 2, the electrical plug connector 1.1 comprises a sleeve 2 as an outer conductor 2.0, an inner conductor pin 3 as an inner conductor 3.0 and a dielectric 4.0 which fills the space between the inner conductor 3.0 and the outer conductor 2.0, the dielectric 4.0 being formed as a cylindrical dielectric body 4 in a two-part manner from a first dielectric part body 4.1 and a second dielectric part body 4.2.
The sleeve 2 of the electrical plug 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 to one another by means of the axial bending section 2.3 already explained above. On the free end face of the holding section 2.1, a connecting flange 2.10 is molded in such a way that the edge region of this end face expands outwards in a funnel-shaped manner and thus creates an abutment surface for abutting against the circuit board 10 and mechanically connecting to the circuit board 10. Furthermore, the connecting flange 2.10 is provided with radial slots 2.11. On the opposite end side of the sleeve 2, the compensation section 2.2 ends in a contact region 2.20 for making electrical contact between the outer conductor 2.0 or the inner conductor 3.0 and the outer conductor 1.210 or the inner conductor 1.240 of the mating plug connector 1.2 (see fig. 7).
Two circumferential lines L1 and L2 adjacent in the axial direction run in the region of the bending section 2.3. As already given by the term "contour", on a given contour the axial coordinates of all points are always the same; therefore, the circumferential lines L1 and L2 are respectively located on a not-shown plane perpendicular to the axial direction.
The second slots 5.1 and 5.2 are arranged on a peripheral line L1, between which there is an unslotted region on the peripheral line L1 and each forms a part-annular connecting bridge 5.0. On the other circumferential line L2, there are likewise two slots 6.2 and 6.2, with the region between the slots 6.2 and 6.2 which is not slotted on the circumferential line L2 as a further annular connecting bridge 6.0. The slots 6.1 and 6.2 located on the circumferential line L2 are arranged offset from one another with respect to the slots 5.1 and 5.2 located on the circumferential line L1, so that the connecting bridges 5.0 and 6.0 are not axially aligned with one another.
The distance a of the two circumferential lines L1 and L2 is small compared to the axial length L of the first electrical plug connector 1.1. The slots 5.1, 5.2, 6.1 and 6.2 have a width b, which may be of the order of mm, for example. The axial length of the connecting bridges 5.0 and 6.0 thus corresponds to the width b of the slots 5.1, 5.2, 6.1 and 6.2. The adjacent position of the two circumferential lines L1 and L2 results in the formation of an annular region 7 between slots 5.1 and 5.2 on circumferential line L1 and slots 6.1 and 6.2 on circumferential line L2. The two sections of the sleeve 2, the holding section 2.1 and the compensating section 2.2, are connected by this annular region 7 and on the one hand by the connecting bridge 5.0 and on the other hand by the connecting bridge 6.0.
By means of such a bending section 2.3 of the sleeve 2, the ability to hinge is achieved, so that the compensation section 2.2 can be bent relative to the holding section 2.1. This elastic bending behavior is also ensured for the dielectric 4.0 and the inner conductor 3.0.
A corresponding bending elasticity for the dielectric 4.0 is achieved in that the dielectric body 4 is made in two parts from a first dielectric body part 4.1 arranged in the holding section 2.1 and a second dielectric body part 4.2 arranged in the compensation section 2.2.
The two dielectric part bodies 4.1 and 4.2 are arranged in the sleeve 2 at a distance by means of a gap 4.3 formed by adjacent end sides 4.11 and 4.21, wherein the gap 4.3 is aligned with the annular region 7 of the bending section 2.3 starting from the circumferential surface of the two dielectric part bodies 4.1 and 4.2.
The two end sides 4.11 and 4.21 of the two dielectric part-bodies 4.1 and 4.2 are configured with contours matching one another. The end side 4.11 of the first dielectric part body 4.1 has a central blind hole 4.12, and the end side 4.21 with the cylindrical projection 4.22 projecting into the blind hole 4.12 is adapted to the blind hole 4.12. The diameter of the projection 4.22 is smaller than the diameter of the blind hole 4.12, so that the gap 4.3 extends labyrinthine from the circumferential surface of the two dielectric part bodies 4.1 and 4.2 to the inner conductor 3.0 beyond the radial distance between the projection 4.22 and the circumferential surface of the blind hole 4.12.
The inner conductor 3.0 as the inner conductor pin 3 is supported in the inner bore 4.10 of the holding section 2.1 and in the inner bore 4.20 of the compensation section 2.2, wherein, in the region of the groove base of the blind hole 4.12 on the end face 4.11 of the holding section 2.1, the inner conductor pin 3 has a cross-sectional constriction 3.1 in the form of a circumferential groove 3.10 with a rectangular cross section, wherein the groove 3.10 extends into the projection 4.22. In the region of the compensation section 2.2 following the slot 3.10, the inner conductor pin 3 has a diameter D which is slightly smaller than the diameter D of the blind hole 4.20 of the second dielectric part body 4.2.
With the inner conductor pin 3 thus configured, together with the two-part dielectric body 4 and the bent section 2.3 of the sleeve 2, the bending resilience of the plug connector 1.1 required for compensating lateral axial misalignment in the symmetry axes a1 and a2 of the electrical plug connector 1.1 and the mating plug connector 1.2 is achieved.
The mating connector 1.2 for the plug connector assembly 1 according to fig. 7 and 8 is shown in the side 14 of fig. 6 and comprises a sleeve 1.21 as the outer conductor 1.210, an inner conductor pin 1.24 as the inner conductor 1.240 and a cylindrical dielectric body 1.26 as the dielectric 1.260 arranged in the outer conductor 1.210.
The mating plug connector 1.2 has a contact section 1.22 on one end, which is formed by the sleeve 1.21 in a stepped manner projecting outward. At the other end of the mating plug connector 1.2, a connection flange 1.23 is formed by the sleeve 1.21, in which connection flange 1.23 the edge region of the sleeve 1.21 is enlarged funnel-shaped in the case of forming an abutment surface for abutment on the circuit board 11 and mechanical connection to the circuit board 11. Furthermore, the connecting flange 1.23 is provided with radial slots 1.230.
Between the connection flange 1.23 and the contact region 1.22, a dielectric body 1.26 is present for receiving the inner bore 1.27 of the inner conductor pin 1.24. The inner conductor pin 1.24 has a slotted and funnel-shaped enlarged blind hole 1.25 at its end projecting into the contact region 1.22 for receiving the inner conductor pin 3 of the electrical plug connector 1.1.
The electrical plug connector 1.1 according to fig. 1 and 2 can also be embodied with more than two slots 5.1 and 5.2 on the circumference L1. Furthermore, instead of two circumferential lines L1 and L2 arranged adjacent to one another in the axial direction, it is also possible to provide only one circumferential line L1 or more than two circumferential lines.
According to fig. 7, the plug connection between the electrical plug connector 1.1 and the mating plug connector 1.2 is realized by means of the contact regions 2.20 of the plug connector 1.1, which are designed as slots, and the contact regions 1.22 of the mating plug connector 1.2, which are designed as plugs.
The contact region 2.20 of the compensation section 2.2 of the sleeve 2 of the plug connector 1.1 has an inwardly directed collar 2.21 extending in the circumferential direction, by means of which the end face of the compensation section 2.2 widens funnel-shaped. To achieve the elastic behavior, axially extending slots 2.22 are provided in the contact region 2.20. The second dielectric part body 4.2 ends before the contact region 2.20, the inner conductor pin 3 projecting into the contact region 2.20.
In order to electrically connect the electrical plug connector 1.1 with the mating plug connector 1.2, the contact section 1.22 of the mating plug connector 1.2 is pushed into the insertion groove formed by the contact section 2.20 of the sleeve 2, so that the groove bottom of the bead section 2.21 abuts against the circumferential surface of the contact section 1.22 of the sleeve 1.21 with electrical contact being made, and at the same time the end of the inner conductor pin 3 of the electrical plug connector 1.1 is inserted into the blind hole 1.25 of the inner conductor pin 1.24 of the mating plug connector 1.2 with electrical contact being made, as can be seen from fig. 7.
Instead of the electrical plug connector 1.1 according to fig. 1 and 2, the electrical plug connector 1.1 according to fig. 3 and 4 can also be used for producing the plug connector 1 according to fig. 7 and 8.
In addition to the holding section 2.1 and the compensation section 2.2, the plug connector 1.1 according to fig. 3 and 4 also has a bending section 2.3, by means of which bending section 2.3 compensation of the lateral or angular misalignment of the axes of symmetry a1 and a2 of the plug connectors 1.1 and 1.2 connected to the circuit board 10 or 11 is likewise achieved in the plug connection with the mating plug connector 1.2 shown in fig. 6 (corresponding to fig. 8).
According to fig. 3 and 4, the electrical plug connector 1.1 comprises a sleeve 2 as an outer conductor 2.0, an inner conductor pin 3 as an inner conductor 3.0 and a dielectric 4.0 which fills the cavity between the inner conductor 3.0 and the outer conductor 2.0, the dielectric 4.0 being formed as a cylindrical dielectric body 4 in a two-part manner from a first dielectric part body 4.1 and a second dielectric part body 4.2.
The sleeve 2 of the electrical plug connector 1.1 according to fig. 3 and 4 consists of three axial sections, namely an axial retaining section 2.1 and an axial compensating section 2.2, which are mechanically connected to one another by means of the axial bending section 2.3 already explained above. On the free end face of the holding section 2.1, a connecting flange 2.10 is molded in such a way that the edge region of this end face expands outwards in a funnel-shaped manner and thus creates an abutment surface for abutting against the circuit board 10 and mechanically connecting to the circuit board 10. Furthermore, the connecting flange 2.10 is provided with radial slots 2.11. On the opposite end side of the sleeve 2, the compensation section 2.2 ends in a contact region 2.20 for electrically contacting the outer conductor 2.0 or the inner conductor 3.0 with the outer conductor 1.210 or the inner conductor 1.240 of the mating plug connector 1.2 according to fig. 5 and 6. In its embodiment, the contact region 2.20 corresponds to the contact region of the electrical plug connector 1.1 according to fig. 1 and 2.
A circumferential line L1 with three slots 5.1, 5.2 and 5.3 that are only a few millimeters narrow extends in the region of the bending section 2.3, on which circumferential line L1 the unslotted regions lie between the slots 5.1, 5.2 and 5.3 and respectively form a connecting bridge 5.0. The slots 5.1, 5.2 and 5.3 are distributed uniformly over the circumference of the sleeve 2 and therefore each have the same central angle.
Starting from the holding section 2.1 of the sleeve 2, the connecting bridge 5.0 extends in a stepped manner into the circumferential surface of the compensating section 2.2 of the sleeve 2 by means of axially and parallel running grooves 5.01, wherein the connecting bridge 5.0 is designed with a bead 5.02 running in the circumferential direction and pointing inwards. By means of the connecting bridges 5.0, which are formed with triangular bead portions 5.02, a pivoting movement of the compensating section 2.2 relative to the holding section 2.1 can be achieved by elastic length compensation of the connecting bridges 5.0, which are formed by crimping.
In order to achieve the bending resilience of the electrical plug connector 1.1 in the region of the bending section 2.3, corresponding to the embodiment according to fig. 1 and 2, a two-part dielectric body 4 is also provided in the plug connector 1.1 according to fig. 3 and 4, which comprises a first dielectric part body 4.1 arranged in the holding section 2.1 and a second dielectric part body 4.2 arranged in the compensation section 2.2. The first dielectric part body 4.1 ends in a radial plane defined by the circumferential line L1 with an end side 4.11. For this purpose, the second dielectric part body 4.2 starts at a distance c from the first dielectric part body through the end side 4.21, as a result of which a gap 4.3 is produced which has a distance corresponding to the distance c.
In order to achieve an inward extension of the connecting bridge 5.0 by means of the bead 5.02, corresponding to the illustration of the section a-a in fig. 5, an axially extending slot 4.23 is provided starting from the circumferential surface of the second dielectric part body 4.2, which slot 4.23 is aligned with the connecting bridge 5.0 and has a depth T which at a minimum corresponds to the height h of the bead 5.02 (see fig. 4), whereas preferably, corresponding to the illustration according to fig. 4, the depth T is greater than the height h of the bead 5.02 relative to the inner wall 2.4 of the sleeve 2.
The inner conductor pin 3, which is embodied continuously with the same diameter, is accommodated in the inner bore 4.10 of the first dielectric part body 4.1 and the inner bore 4.20 of the second dielectric part body 4.2.
In the electrical plug connector according to fig. 3 and 4, less than three slots 5.1, 5.2 and 5.3 or more than three slots can also be provided on the circumferential line L1. In the case of three slots, this results in a connecting bridge 5.0 with three associated grooves 4.23 (see fig. 5). With more than three slots 5.1, 5.2 and 5.3, a corresponding number of connecting bridges 5.0 with associated slots 4.23 is also required.
The gap 4.3 between the first and second dielectric part bodies 4.1 and 4.2 of the electrical plug connector according to fig. 1 to 4 is adapted to the requirements of the respective application.
Fig. 9 shows an electrical plug connector 8.1 which, together with a corresponding mating plug connector 8.2 according to fig. 10, forms a plug connector assembly 8 as a B2B connector for electrically connecting two circuit boards to one another, as shown in fig. 11. To this end, according to fig. 11, the electrical plug connector 8.1 is mechanically and electrically connected with one circuit board by means of its connecting flange 8.10, and the mating plug connector 8.2 is mechanically and electrically connected with the other circuit board by means of its connecting flange 8.23.
The main difference between the plug connector assembly 8 according to fig. 9 to 11 and the plug connector assembly 1 described above is that in the electrical plug connector 8.1 the contact section 9.20 is enlarged in the direction of the plug-side end of its sleeve 9 and is bridged by the contact section 8.22, which has a funnel-shaped widening of the projection 8.21b as an insertion aid, in order to ensure good electrical contact.
The electrical plug connector 8.1 and the mating plug connector 8.2 differ from the electrical plug connector 1.1 and the associated mating plug connector 1.2 with regard to the embodiment of their sleeves 9 and 8.21 and are otherwise structurally identical. In particular, the connection of the inner conductors is implemented as in the plug connector assembly 1.
Like the sleeve 2 of the electrical plug connector 1.1, the sleeve 9 of the electrical plug connector 8.1 also consists of three axial sections, namely an axial retaining section 9.1 and an axial compensating section 9.2, which are mechanically connected by an axial bending section 9.3. The free end face of the holding section 9.1 is also provided with a connecting flange 9.10 by molding in such a way that the edge region of the end face expands outwards in a funnel-shaped manner and thus creates an abutment surface for abutting and mechanically connecting to the circuit board. Furthermore, the connecting flange 9.10 is provided with radial slots.
On the opposite end side of the sleeve 9, the compensation section 9.2 is in a contact region 9.20 for electrically contacting the outer conductor 9.0 with the outer conductor 8.210 of the mating plug-in connector 8.2 (see fig. 11).
The contact region 9.20 of the compensation section 9.2 of the sleeve 9 of the plug connector 8.1 is enlarged substantially funnel-shaped, wherein a contact surface 9.23 is realized by means of a circumferentially extending, outwardly directed bead 9.21, which is in front of the end face end of the compensation section 9.2, said contact surface forming the radially outermost section of the contact region 9.20.
To achieve the elastic behavior, axially extending slots 9.22 are provided in the contact region 9.20. Preferably, the second dielectric part body also ends before this contact region 9.20, wherein the inner conductor pin projects into the contact region 9.20.
The bending section 9.3 is constructed identically to the bending section 2.3 of the plug connector 1.1, so that the same reference numerals are used for it and the description thereof refers to the corresponding description of fig. 1 and 2.
A mating plug connector 8.2 for the plug connector assembly 8 according to fig. 11 is shown in fig. 10 and comprises a sleeve 8.21 as an outer conductor, in which sleeve an inner conductor pin as an inner conductor and a cylindrical dielectric body as a dielectric are arranged.
The mating plug connector 8.2 has a contact region 8.22 at one end, which is formed by a section 8.21a of the sleeve 8.21 and a projection 8.21b which widens funnel-shaped in the direction of the electrical plug connector 8.1. At the other end of the mating plug-in connector 8.2, a connecting flange 8.23 is formed by the sleeve 8.21, in which connecting flange 8.23 the edge region of the sleeve 8.21 is enlarged in funnel-like manner with the formation of an abutment surface for abutment on and mechanical connection with the circuit board. Furthermore, the connecting flange 8.23 is provided with radial slots 8.230.
