Technical Field

The invention relates to a plug connector according to claim 1 and a plug connection device having a first plug connector and a second plug connector having the features of claim 13.

Background

Plug connection devices of different designs are known from the prior art and comprise a first plug connector and a second plug connector, wherein the respective plug connector comprises a housing and at least one conductor and, upon a plug-in mating of the two plug connectors in a plug-in direction, the respective conductors are brought into electrical contact, as a result of which a transmission of electrical signals is effected between the conductors of the first plug connector and the conductors of the second plug connector. On the one hand, the transmission of the electrical signals should take place as loss-free as possible, and on the other hand, the plug connection should be horizontally and vertically offset in order to compensate for tolerances between the two components to be electrically connected. For such plug connections, coaxial plug connections are generally used in the prior art, which are often designed in a multi-part plug connection for high frequencies up to 6GHz in an SMP design.

It has been found to be disadvantageous in this prior art that the plug connection devices known from the prior art only allow a small axial offset between the conductors to be coupled in each case, and are prone to errors and expensive due to the complicated construction, in particular when using such plug connection devices as multi-stage conductors.

Disclosure of Invention

It is therefore an object of the present invention to provide an improved plug connector and an improved plug connector device which, on the one hand, permit as wide an axial offset as possible between the conductors to be connected, not only horizontally but also vertically, ensure the transmission of fault-free and error-free electrical signals, in particular high-frequency electrical signals, achieve a compact and weight-saving design and can be arranged on the respective printed circuit board in a fully automated manner by means of a so-called "pick-and-place" positioning system, for example as a component with SMT functionality.

The above object is achieved by the invention by a plug connector having the features of claim 1 and a plug connection device having a first plug connector and a second plug connector having the features of claim 13.

The dependent claims contain advantageous developments of the invention.

The plug connector according to the invention comprises: at least one housing having at least one recess; and at least one single-piece conductor and at least one outer conductor, wherein the at least one conductor includes a first leg having a first end and a second leg having a second end, wherein the second leg of the at least one conductor is partially retained in the groove of the housing. Preferably, the second leg of the at least one conductor is held securely on the housing, and more preferably securely electrically insulated, in the region of the second end. At least one spring region is arranged between the first leg and the second leg, wherein the first leg or the first end of the conductor is elastically deflectable around the spring region to compensate for axial offset. Although the conductor is held in the region of the second leg in a manner supported at one end by the housing, the conductor is arranged in the region of the first leg in a freely movable and elastic manner at the other end by the spring region. Here, the first leg is preferably freely movable within the recess of the housing. The first free end is arranged to establish an electrical connection with the second plug connector and the second end may protrude from the housing to establish an electrical connection with an electrical component, in particular a printed circuit board. When the plug connector is transferred to the plugged state with the second plug connector, the axial offset can be compensated for by the elastic deformation of the spring region alone without producing stresses in the respective conductor at the elastic material limit. In addition, it is preferred that the first leg is arranged coaxially to the plugging direction, so that the first leg can be deflected elastically relative to the second leg by the spring region with an axial offset. Thereby, an axial offset between the respective conductors when shifting into the plugged-in state can be compensated.

According to the invention, it is proposed that the outer conductor is arranged at least partially around the at least one conductor. More preferably, the outer conductor is arranged locally coaxially around the at least one conductor and electrically but also electromagnetically shields the conductor, which is particularly preferably designed as an inner conductor. In particular, high-frequency electrical signals can thus be transmitted without interference via the at least one conductor. Particularly preferably, the outer conductor at least partially surrounds the first leg of the at least one conductor, whereby the first leg of the at least one conductor is mechanically protected on the one hand and not only electrically but also magnetically shielded on the other hand.

Furthermore, it is proposed according to the invention that the outer conductor has a spring cup at the first end and at the second end. It is particularly further advantageous if a dielectric is arranged between the conductors and the outer conductor, wherein the dielectric in a preferred embodiment couples the first leg of the at least one conductor with the outer conductor such that the respective conductor or the inner conductor and the outer conductor together can compensate for axial offset. In addition, the spring cup can make an electrical connection with the housing at the second end of the outer conductor when the axial offset is compensated, and on the other hand an additional restoring force can be applied to the outer conductor and the inner conductor by the spring force of the spring cup.

A further advantageous embodiment of the invention provides that the second leg is arranged at an angle. Preferably, the angle sandwiched between the two legs is less than 180 °. More preferably, the second leg is arranged at an angle of 135 °, even more preferably 90 °, to the first leg, whereby, on the one hand, particularly preferably, the spring region allows a pivoting movement on an axis perpendicular to the plugging direction, and, more preferably, on the other hand, the at least one conductor can perform a sprung movement in the plugging direction. Alternatively, the spring region may be arranged on the axis of the first and second legs, in a Z-shape, S-shape, serpentine shape or in any way have a non-linear shape.

More preferably, the spring region of the at least one conductor comprises at least one curvature. The at least one curvature is preferably constituted by a bend having an approximately constant radius, wherein the radius is a multiple of the average diameter of the at least one conductor in the first leg and/or the second leg.

Preferably, the curvature of the at least one conductor is also designed such that the stresses occurring in the conductor in the axial deflection compensation are kept as low as possible and within the elastic material limits. Preferably, the at least one conductor is circular in cross section in the region of the curvature, so that a uniform stress profile is produced in the at least one conductor at any deflection.

A further advantageous embodiment of the invention provides that the spring region between the first leg and the second leg of the at least one conductor comprises at least one cross-sectional taper. The cross-sectional taper can provide the spring region with a bending stiffness that is less than the bending stiffness of the conductor in the first leg and/or the second leg. It is particularly preferred, however, that the cross-sectional taper reduces the bending stiffness in the spring region, for example by 5 to 75%, compared to the bending stiffness in the first leg and/or the second leg. The cross-sectional taper allows the restoring force of the first leg of the at least one conductor of the spring region to be set, wherein a low restoring force facilitates an easy transfer of the plug connection device into the plugged state when it is axially deflected.

In addition, it has proven to be advantageous if the second end of the outer conductor is arranged in the plug-in direction in a common plane with the spring region. The outer guide, which preferably has a spring cup at the second end, is thus arranged particularly closely adjacent to the axis about which the first leg pivots when deflected to compensate for the axial offset. More preferably, the second end of the outer conductor is engaged into an undercut. The undercut can be formed or machined into the groove of the housing, wherein even more preferably the undercut is designed as a radial groove and particularly preferably as a radial groove with a rounding-off. The outer conductor can thus be electrically contacted in the pivoting of the first leg, preferably by the circumference, as completely as possible in the recess or undercut.

In addition, it is advantageous if the at least one conductor or its first leg is arranged freely movably in the recess in the housing. The recess may define a maximum compensatable axial offset or a maximum angle at which the first leg may deflect upon deflection, wherein preferably the spring region is only elastically deformed. It is thereby ensured that the spring region does not prematurely break due to material fatigue and the conductive contact in the conductor is interrupted.

In a further advantageous embodiment of the invention, it is provided that the recess is partially conical and comprises a conical region. In particular, it is preferred here that the recess has a continuously tapering shape starting from the first end of the conductor. A maximum deflection for compensating an axial offset of the at least one conductor or of the first leg of the at least one conductor and the outer conductor is predetermined by the conical region of the recess.

It is particularly advantageous if the housing is made of an electrically conductive material, whereby the at least one conductor in the housing does not require additional electrical or electromagnetic shielding by an outer conductor. In particular, it can be advantageous if the housing is formed in one piece or in multiple pieces, further preferably by injection molding, and is formed in a mounting-and weight-optimized manner.

Advantageously, the housing comprises fastening means arranged to be connected to the printed circuit board. In this case, it is also particularly preferred that the first plug connector and/or the second plug connector can be arranged on a printed circuit board by means of a mechanical positioning device (pick-and-place) and can be coupled to the printed circuit board using SMT functionality.

Another aspect of the invention relates to a plug connector with a first plug connector and a second plug connector, wherein the first plug connector is designed with a first housing and at least one conductor and the second plug connector is also designed with a first housing and at least one conductor. The first plug connector and the second plug connector can be transferred in each case in one plugging direction into a plugged-in state, wherein in the plugged-in state of the plug connector device an electrical connection is established between the respective at least one conductor between the first plug connector and the second plug connector. According to the invention, at least one of the plug connectors is designed such that the at least one conductor of the first plug connector and/or the at least one conductor of the second plug connector comprises a spring region, by means of which a circumferential offset between the respective conductors can be compensated elastically.

Detailed Description

The plug connection device 1 according to the invention comprises a first plug connector 10 and a second plug connector 50. The plug connector 10 shown in perspective view in fig. 1 can be transferred to the plugged state together with the second plug connector 50 shown in perspective view in fig. 2. The plugged-in state of the plug connection 1 according to the invention can be seen from the sectional view according to fig. 3, wherein the section of the sectional view corresponds to section B-B according to fig. 4.

The plug connector 1 serves, for example, as an antenna contact which transmits a large number of high-frequency signals between the two components via the conductor pair in an electrically and magnetically shielded manner as optimally as possible. In the exemplary embodiment shown, the first plug connector 10 and the second plug connector 50 each comprise five conductor pairs, each plug connector 10, 50 having a single- piece conductor 12, 52, wherein the number of conductor pairs can be selected at will. The conductors 12, 52 in the respective first plug connector 10 and the respective second plug connector 50 are preferably of identical construction.

The first plug connector 10 shown in detail in fig. 1, 4, 5 and 6 comprises a housing 11, which housing 11 encloses a conductor 12.

The housing 11 is made of an electrically conductive material, for example of aluminum, and comprises a recess 30 with a plug-in region 31, into which recess 30 a second plug-in connector 50 can be introduced locally to establish an electrical connection of the conductor pairs.

The conductor 12 is made electrically conductive in its entirety and comprises a first end 13 and a second end 14, wherein the first end 13 is arranged to establish an electrically conductive connection with a corresponding conductor 52 of the second plug connector 50. The second end 14 of the conductor 52 may be connected to an electrical component, such as a printed circuit board (not shown).

The respective conductor 12 can be divided into three regions, namely a first leg 41, a second leg 42 and a spring region 40, wherein the spring region 40 is arranged between the first leg 41 and the second leg 42. Although the first leg 41 of the conductor 12 is aligned in the plugging direction 5, the second leg 42 can be aligned at an angle, preferably perpendicular to the first leg 41 as in the illustrated embodiment. The spring region 40 is designed as a rocker spring with a curvature 45 and can be produced by deformation, in particular bending, from an electrical conductor which is designed in one piece. The spring region 40 is in a free state in the recess 30 of the housing 11.

The second leg 42 or the second end 14 of the conductor 12 is held on the housing 30 in an electrically insulated manner by means of the dielectric 38 and projects from the housing 11 in order to establish an electrical connection to a printed circuit board, not shown.

With reference to fig. 5, 6 and 7, the first leg 41 projects freely into the recess 30 of the first housing 11 in alignment in the plugging direction of the first plug connector 10 and is freely pivotable in this recess 30.

The conductor 12 may be surrounded by a dielectric 38 and an outer conductor 35, which dielectric 38 and outer conductor 35 may combine to project integrally into the recess 30 and to pivot together from the spring region 40 about at least one axis perpendicular to the plugging direction 5 at an angle α, as shown in fig. 6.

The recess 30 comprises a plugging region 31 and a tapered region 32, the tapered region 32 being provided with a cross section tapering continuously from the first end 13 of the conductor 12. The tapered region 32 is formed as a tapered recess symmetrical to the first leg 41. Thus, each conductor 12 of the conductor pair has its own tapered region 32 in the recess 30.

The tapered region 32 enables free pivoting of the first leg 41 in the groove 30. The conical region 32 can also predetermine the maximum deflection of the first leg 41 and for this purpose have a constant opening angle. The opening angle of the conical region is selected such that the spring region 40 is elastically deformed only within the elastic material boundary when the first leg 41 is deflected, and premature mechanical failure of the spring region 40 and separation or fracture of the electrical conductor 12 are prevented. At maximum deflection of the first leg 41, the first leg 41 preferably rests on the tapered region 32. Further preferably, the opening angle is typically >0 ° and <60 °, such that the maximum deflection for compensating axial offset in each direction is about half of the opening angle.

The outer conductor 35 is a conductive sleeve which surrounds the first leg 41 or the conductor 12 in the region of the first leg 41 and is arranged mechanically securely in electrical isolation from the conductor 12 by means of the dielectric 38. The outer conductor 35 may preferably be circular in cross-section. Furthermore, it can be seen in particular from fig. 5 that the outer conductor 35 comprises a spring cover 39 both at the first end 36 and at the second end 37.

The spring cover 39 is approximately circular in cross section and consists of a plurality of projecting and elastic spring tongues, which can project radially and axially. The spring tongues of the spring cup 39 press at the second end 37 against the recesses 30 of the housing 11 and can electrically connect the outer conductor 35 to the housing 11. Here, the second end 37 of the outer conductor 35 or of the spring cup 39 is arranged in such a way that the second end 37 is arranged in a common plane with the spring region 40.

The second end 37 of the outer conductor 35 or of the spring cup 39 is adjacent and further preferably arranged on an axis about which the first leg 41 is pivoted by the spring region 40 at an angle α when deflected to compensate for the axial offset, furthermore, the spring tongue can generate a restoring force in addition to the spring region 40 when the first leg 41 is deflected, thereby restoring the first leg 41 to the starting position, for which purpose the spring tongue of the spring cup 39 can engage in an undercut 33 at the second end 37 of the outer conductor 35, which undercut 33 is further preferably designed as a circular radial groove which is circumferentially symmetrical.

The first end 36 projects over the conductor 12 opposite the plugging direction 5 shown in fig. 5 by means of an arrow, so that on the one hand the conductor 12 is protected and on the other hand the centering of the second plug connector 50 when it is transferred into the plugged-in state takes place, as will be explained in more detail below.

The second plug connector 50 is shown in fig. 2 and 3 and comprises a housing 51 and a conductor 52, the conductor 52 having a first end 53 and a second end 54. The housing 51 of the second plug connector 50 engages in the conductor 52, wherein the conductor 52 is held in the housing 51 in an electrically insulated manner by means of a dielectric 68. The first end 53 of the conductor 52 is arranged to establish an electrical connection with the first end 13 of the conductor 12 of the first plug connector 10. The second end 54 protrudes freely from the housing 52 and is preferably configured to establish an electrical connection, for example, with a printed circuit board or another electrical component.

The housing 51 also has for each conductor 52a contact sleeve 65 projecting in the plugging direction 6, wherein the contact sleeve 65 is arranged to engage into the recess 30 of the first plug connector 10. As shown in fig. 3, the contact sleeve 65 engages around the outer conductor 35 of the first plug connector 10 in the plugged state and has a conical opening 66, through which conical opening 66 the centering of the spring cap 39 can take place.

The electrical conductors 52 and the housing 51 of the second plug connector 50 are preferably L-shaped, so that the conductors 52 have a first leg and a second leg which are arranged at an angle of 90 ° to one another. The first leg is aligned in the plugging direction 6. The angle between the first and second legs of the conductor 52 may be formed by deformation, for example by bending.

Fig. 3 furthermore shows that the contact sleeve 65 projects beyond the conductor 52 in the plugging direction 6, so that it is ensured that, when the first and second plug connectors 10, 50 are transferred into the plugged state, first of all the first end 36 of the outer conductor 35 contacts the contact sleeve 65, as a result of which the conical opening 66, the pivotably held first leg 41 and the spring action of the spring tongues of the spring cover 39 can elastically compensate for the axial offset between the conductors 12, 52, and the plug connection 1 according to the invention can compensate for wide tolerances.

Fig. 3 also shows that the first ends 53 of the conductors 20 of the second plug connector 50 are sleeve-shaped and are arranged to engage around the first ends 13 of the conductors 12 in the plugged state.

Both the housing 11 of the first plug connector 10 and the housing 51 of the second plug connector 50 can be designed in a weight-and production-optimized manner. For weight-optimized production of the first plug connector 10 and the second plug connector 50, recesses 17, 57 can be provided, by means of which recesses 17, 57 a rigid and tilt-proof arrangement on the components and a weight reduction can be achieved.

The housing 11 of the first plug connector 10 and the housing 51 of the second plug connector 50 may preferably each be constructed in multiple parts and more preferably be made of a light metal, preferably aluminum, in an injection molding process. In a further method step, the conductor 12, 52 is partially encapsulated, in particular injection-molded, with the dielectric 38, 68, and the outer conductor 35 is arranged on the first leg 41 of the conductor 12. Subsequently, the conductor 12, 52 is deformed and preferably formed into an L-shape by bending, and then inserted into the housing 11, 51. The insertion into the housings 11, 51 preferably takes place from the rear side of the respective housing 11, 51 in the plugging direction 5, 6, respectively. The housing 11, 51 is closed, for example, by means of a second electrically conductive housing part and can be mounted as an SMD component on an electrical component, for example a printed circuit board.
