Technical Field

The invention relates to a circuit board having a plug connector interface for direct contact with a plug connector and to an electrical plug connector arrangement having such a circuit board and a plug connector connected directly to the circuit board.

Background

For the electrical connection of adjacent and parallel-aligned circuit boards, plug connectors are used which are fastened to opposite sides of the circuit board. Such plug connectors, which are referred to as B2B (board-to-board) connectors, comprise three plug parts, namely two sockets which are each fastened to a circuit board and an adapter (also referred to as a bullet) which is each designed as a plug at both ends. With such an adapter, it is possible to compensate not only for tolerance compensation with respect to the spacing between the circuit boards to be connected, but also for transverse shaft offsets with respect to the longitudinal axes of the two sockets. This three-piece design of the B2B plug connector can be regarded as a disadvantage.

An electrical plug connector is known, for example, from DE 102018113278B3, which, together with a mating plug connector, makes a B2B plug connection. This known B2B plug connection comprises only two plug parts, namely an electrical plug connector and a mating plug connector. The electrical plug connector is mechanically and electrically connected to the circuit board by means of a flange which is arranged on the end side on the sleeve as the outer conductor and is widened in a funnel shape, while the mating plug connector is likewise mechanically and electrically connected to the other circuit board by means of a flange which is arranged on the end side on the sleeve as the outer conductor and is widened in a funnel shape. Tolerance compensation for the transverse axial offset is achieved in the electrical plug connector by means of flexible bending sections of the sleeve of the plug connector.

Disclosure of Invention

The object of the invention is to provide a circuit board with which direct contact with an electrical plug connector can be made. It is also an object of the invention to provide an electrical plug connection with the circuit board for establishing direct contact with an electrical plug connector.

The first object is achieved by a circuit board according to the invention.

Such a circuit board comprises a plug connector interface for direct contact with a plug connector, wherein the plug connector interface on the front side of the circuit board is configured with:

a contact pin, which is arranged centrally in the blind hole with the formation of the annular cylindrical insertion chamber, and which has an inner bore with a first contact region for an inner conductor for contacting an inner conductor of a plug connector; and

a second contact region of the outer conductor, which is arranged in the insertion chamber, is used for contacting the outer conductor of the plug connector.

With such a circuit board according to the invention, the plug connector interface is mechanically and electrically connected directly to the plug connector. The plug connector itself is mechanically connected to the other circuit board via flanges provided on the opposite ends of its sleeve in order to produce a B2B plug connection, so that only a single plug is required for this purpose.

In the circuit board according to the invention, the plug connector interface assumes the function of a socket for the plug connector. According to the invention, the plug connector interface has an insertion chamber into which the plug-side end of the plug connector is inserted, so that on the one hand a mechanical and electrical connection can be established between the contact regions of the respective outer conductors and on the other hand a mechanical and electrical connection can be established between the contact regions of the respective inner conductors.

To this end, according to an advantageous development of the invention, the insertion chamber has a contact section with the second contact region and a funnel section with a chamfer widening radially towards the front side of the circuit board. Preferably, the contact pins are configured with a length that is inserted into the contact section of the chamber. By means of the funnel section, the plug-side end of the plug connector can be introduced into the insertion chamber in a manually improved manner.

According to a further preferred embodiment of the invention, the inner conductor is guided onto a conductor track plane opposite the front side of the printed circuit board and is electrically connected to the conductor tracks of the conductor track plane. The conductor circuit plane can be realized as an embedded conductor circuit plane of a multilayer circuit board or be present as a conductor circuit plane on the rear side of the circuit board opposite the front side.

Furthermore, it is advantageous according to a further embodiment of the invention for the second contact region to be arranged at least on the outer side of the annular cylindrical insert chamber. Thus, a more reliable electrical contact for the sleeve of the plug connector, which sleeve is in the form of an outer conductor, can be ensured, since the electrical contact is usually made by means of an elastic section of the sleeve having a circumferential rim.

Furthermore, according to a development, it is advantageous if the outer conductor is guided onto a conductor circuit plane opposite the front side of the printed circuit board and is electrically connected to the conductor circuit of said conductor circuit plane. The conductor circuit plane can be realized as an embedded conductor circuit plane of a multilayer circuit board or be present as a conductor circuit on the rear side of the circuit board opposite the front side.

For manual operation for introducing the plug-side end of the plug connector into the plug connector interface, the inner bore of the contact pin is formed with a radially widened chamfer on the end side.

In order to ensure reliable mechanical and electrical contact of the plug connector with the plug connector interface of the circuit board, the radial width of the annular cylindrical insertion chamber is adapted to form a sleeve of the outer conductor of the plug connector in order to establish a resilient plug contact.

The second-mentioned object is achieved by an electrical plug connection according to the invention.

Such an electrical plug connector arrangement with a circuit board according to the invention and a plug connector which interfaces with the plug connector of the circuit board is distinguished in that,

for contacting the first contact region of the plug connector interface, the plug connector has an inner conductor in the form of an inner conductor pin for insertion into an inner bore of a contact pin of the plug connector interface;

the plug connector has an outer conductor embodied as a sleeve, which has a contact region for contacting a second contact region of the plug connector interface; and

the plug connector has a dielectric body with an inner bore for receiving the inner conductor pin, wherein the dielectric body is arranged in the sleeve.

In the electrical plug connector arrangement according to the invention, no mating plug connector, as proposed in the above-mentioned DE 102018113278B3, is required for the plug connector, which is arranged on the circuit board. The plug connector described there interfaces with a plug connector of a circuit board, the free end of the plug connector preferably being mechanically connected directly to the other circuit board via the flange of its sleeve in order to establish a B2B plug connection.

Drawings

The invention is described in detail below with the aid of embodiments and with reference to the attached drawings. In the figure:

figure 1 shows a perspective view of an electrical plug connector arrangement consisting of a circuit board according to the invention and a plug connector directly connected thereto;

fig. 2 shows a sectional view of the plug connector arrangement of fig. 1; and

fig. 3 shows a sectional view of a circuit board according to the invention with a plug connector interface.

Detailed Description

Fig. 1 shows a perspective view and fig. 2 shows a sectional view of an electrical plug connector arrangement 100 comprising a circuit board 1 with a plug connector interface 1.0 and a plug connector 10 which is directly electrically and mechanically connected to the circuit board 1 via the plug connector interface 1.0.

The plug connector interface 1.0 is formed according to a socket in the circuit board 1 which is adapted to the plug connector 10. The plug connector 10 comprises a sleeve 11 (see fig. 2) with a dielectric body 13, wherein an inner conductor pin 12 is arranged centrally in the dielectric body 13 as an inner conductor 12.0 of the plug connector 10 in the bore. The sleeve 11 forms the outer conductor 11.0 of the plug connector 10.

The sleeve 11 of the plug connector 10 comprises a plurality of sections, namely a plug-side equalization section 11.1, which has an end-side contact zone 11.10, with which a contact with the plug connector interface 1.0 of the circuit board 1 is established; a holding section 11.2 having an end-side connection flange 11.20, which can be brought into electrical and mechanical connection with a further printed circuit board (not shown); and a curved section 11.3 connecting the balancing section 11.1 with the holding section 11.2. The compensation of tolerances for the transverse axial offset between the balancing section 11.1 and the holding section 11.2 is achieved by means of the bending section 11.3 in that the bending section 11.3 of the sleeve 11 is designed with a plurality of tangentially extending slits 11.31 and 11.32.

Furthermore, it is necessary for the transverse axial displacement to be achieved that the dielectric body 13 of the plug connector 10 is composed of two sub-dielectric bodies 13.1 and 13.2. Starting from contact region 11.10 of balancing section 11.1, first sub-dielectric 13.1 extends partially into bending section 11.3, while second sub-dielectric 13.2 is connected to first sub-dielectric 13.1 with gap 15 and extends into the region of holding section 11.2. The inner sleeve 14 covers the bending section 11.3, but does not limit the bendability of the bending section 11.3.

Finally, an adaptation of the inner conductor pin 12 is also necessary for achieving a transverse axial offset. For this purpose, the inner conductor pin 12 has a cross-sectional taper 12.2 in the region of the gap 15, which is configured as a groove.

According to fig. 2 and 3, the plug connector interface 1.0 is realized as a blind hole 1.1 from the front side V of the circuit board 1, wherein the blind hole 1.1 is provided with a chamfer 1.60, so that a funnel-shaped opening is formed. In the center of the blind hole 1.1, a contact pin 1.2 is arranged, which is surrounded by an annular cylindrical insertion chamber 1.10. Starting from the bottom 1.12 of the blind hole 1.1, the blind hole 1.1 therefore comprises a contact section 1.5 forming the insertion chamber 1.10 and a funnel section 1.6 having a chamfer 1.60. The length of the contact pin 1.2 located above the bottom 1.12 is therefore equal to the height of the contact section 1.5.

The contact pin 1.2 has an inner bore 1.20 provided with a chamfer 1.21, which has a first contact area 1.30 as the inner conductor 1.3 of the plug connector interface 1.0 for contacting the inner conductor 12.0 of the plug connector 10. Only the inner conductor 1.3 with the contact region 1.30 is shown in fig. 3. The contact region 1.30 is located on the side of the inner bore 1.20 leading to the rear side R of the printed circuit board 1. The inner conductor 1.3 transitions on the rear side R of the printed circuit board 1 to the conductor track 1.70 of the conductor track plane 1.7 arranged on the rear side R of the printed circuit board 1.

The bottom 1.12 of the insertion chamber 1.10 is a circular ring-shaped surface which is connected to the rear side R of the circuit board 1 via a plurality of contact holes 1.13 (see fig. 2).

According to fig. 3, the second contact region 1.40 is located as the inner conductor 1.4 of the plug connector interface 1.0 on the outer side 1.11 and partially on the bottom 1.12 of the insertion chamber 1.10, so that the region of the contact opening 1.13 is also covered. The contact hole 1.13 is contacted through the rear side R of the printed circuit board 1 and is connected to the conductor track 1.71 of the conductor track plane 1.7. The second contact region 1.40 is electrically connected to the outer conductor 11.0 of the plug connector 10.

For the direct electrical and mechanical connection of the plug connector 10 to the plug connector interface 1.0 of the circuit board 1, the plug-side end of the plug connector 10 is inserted into the blind hole 1.1 of the plug connector interface 1.0 using the contact region 11.10 of the sleeve 11 and the insertion pin 12.1 of the inner conductor pin 12. Here, the insertion pin 12.1 is accommodated by the inner bore 1.20 and at the same time the contact region 11.10 is accommodated by the insertion chamber 1.10. The chamfers 1.60 and 1.21 facilitate the manual insertion of the plug connector 10 into the blind hole 1.1.

In order to ensure both a good electrical connection between plug connector 10 and plug connector interface 1.0 and a reliable mechanical connection between the plug connector and the plug connector interface, on the one hand, insertion pins 12.1 of inner conductor pins 12 are cut crosswise, so that elastic contact arms 12.10 are produced. The diameter of the inner bore 1.20 is adapted to the contact arms in such a way that, when the insertion pin 12.1 is introduced into the inner bore 1.20, the contact arms 12.10 are pressed together against their same spring force.

On the other hand, the width W of the annular cylindrical insert chamber 1.10 is adapted in the radial direction to the contact pressure plate 11.11 of the contact region 11.10. A plurality of contact lugs 11.11 are each separated by a slit running in the longitudinal direction of the plug connector 10, which are flared radially outward for producing a spring effect and have a circumferential rim on the end side. As the contact area 11.10 is introduced into the insertion chamber 1.10, the contact pressure plate 11.11 is pressed radially inwards against the force of the spring, with the rim of the contact pressure plate abutting against the second contact area 1.40.

A blind hole 13.10 is provided at the end side of the first sub-dielectric 13.1, into which blind hole the inner conductor pin 12 projects with the aid of the insertion pin 12.1. If the plug connector 10 is connected to the plug connector interface 1.0, the contact pins 1.2 project into the blind holes 13.10.

In the circuit board 1 shown in fig. 3, a conductor circuit plane 1.7 with conductor circuits 1.70 and 1.71 is present on the rear side R. The conductor circuit plane may also be an embedded conductor circuit plane of a multilayer circuit board.
