Accordingly, an electrical connection arrangement for an electrical plug connector comprises a first electrical contact element extending in the direction of a first central axis, a second electrical contact element extending in the direction of a second central axis, and a printed circuit board. The printed circuit board has a front surface, a rear surface, and side surfaces which connect the front surface to the rear surface. The printed circuit board further comprises an electrical functional element, a first contact spring, and a second contact spring. The contact springs are in electrically conductive contact with the electrical functional element. The first contact spring is resiliently connected to the first contact element, and the second contact spring is resiliently connected to the second contact element.The two central axes run parallel to each other and define a reference plane. The circuit board lies entirely within an installation space. Viewed in the direction of the central axes, the installation space is delimited by the two contact elements and two boundary planes.

The second boundary plane runs parallel to the reference plane and through a second surface line, which lies opposite the first surface line with respect to the central axis of the contact element.

[0058] DESCRIPTION OF PREFERRED EMBODIMENTS

[0059] Figures 1 to 8 show various embodiments of an electrical connection arrangement for an electrical connector. Identical parts are provided with the same reference numerals. Figure 9 shows a printed circuit board 3, which is used in both embodiments of the electrical connection arrangement.

[0060] The electrical connection arrangement shown in the figures forms part of an electrical connector. The electrical connection arrangement provides an assembly for the electrical connector, which can be used, for example, as a housing of the connector. The electrical connector is preferably a connector in the field of electromobility.

[0061] The electrical connection arrangement according to both embodiments for the electrical connector comprises a first electrical contact element 1 extending in the direction of a first central axis M1, a second electrical contact element 2 extending in the direction of a second central axis M2, and a printed circuit board 3. The two central axes M1, M2 run parallel to each other and define the plug-in direction of the connector. The two central axes M1, M2 span a reference plane R. The reference plane R is a virtual plane that will be used to define the arrangement of the printed circuit board 3 below.

[0062] In the embodiment shown, the cross section of the first contact element 1 is larger than the cross section of the second contact element 2. The first contact element 1 is preferably a power contact and the second contact element 2 is preferably a signal contact.

[0063] The circuit board 3 has a front surface 4, a rear surface 5, and side surfaces 6 that connect the front surface 4 to the rear surface 5. The circuit board 3 is designed as a flat cuboid. An electrical functional element 7, a first contact spring 8, and a second contact spring 9 are arranged on the front surface 4 of the circuit board 3. The contact springs 8, 9 are in electrically conductive contact with the electrical functional element 7.

[0064] Furthermore, the first contact spring 8 is resiliently connected to the first contact element 1 in an electrically conductive manner, and the second contact spring 9 is resiliently connected to the second contact element 2 in an electrically conductive manner. Thus, the contact elements 1, 2 are electrically connected to the electrical functional element via the contact springs 8, 9.

[0065] The printed circuit board 3 lies entirely within an installation space E, which is delimited by the two contact elements 1, 2 and two boundary planes B1, B2. The boundary planes B1, B2 are shown in Figures 2 and 6 and run perpendicular to the surface of the drawing sheet. Both boundary planes B1, B2 run parallel to the reference plane R. The first boundary plane B1 lies on one side of the reference plane R, and the second boundary plane B2 lies on a side of the reference plane R opposite the aforementioned side.

[0066] The first boundary plane B1 continues through a first surface line L1 of a reference diameter of one of the two contact elements 1, 2. Here, the first surface line L1 is assigned to the first contact element 1. However, the first surface line L1 can also be assigned to the second contact element 2. The surface line L1 runs parallel to the first central axis M1 and is shown in Figure 1. The second boundary plane B2 continues through a second surface line L2, which lies opposite the first surface line L1 with respect to the central axis M1 of the aforementioned contact element, here the first contact element 1. The surface lines L1, L2 here lie on the maximum diameter of the first contact element 1.

[0067] The surface lines L1, L2 can also lie on the maximum diameter of the second contact element 2, whereby the maximum diameter of the second contact element 2 is smaller than the maximum diameter of the first contact element. In this variant, the two reference planes B1, B2 are closer to each other than in the variant shown in Figures 2 and 6. However, the circuit board shown in these figures also lies between the two reference planes B1 and B2 in this case.

[0068] The surface line L1, L2 is preferably defined as the intersection line between the cylindrical outer side of the respective contact element on the reference diameter and a plane passing through the respective central axis and at right angles to the reference plane R.

[0069] Between the two boundary planes B1, B2, the installation space E is delimited by the lateral surfaces of the two contact elements 1, 2 located between the two boundary planes B1, B2. The lateral surfaces can be the surfaces on which the aforementioned surface line lies, or they can also be other surfaces. In the embodiment shown, these are the surfaces located below the contact surfaces 15, 16, which are described in more detail below.

[0070] In the direction of the central axis M1, M2, the installation space has an extension which is typically smaller than the extension between the first contact element 1 and the second contact element 2 and / or than the extension between the two reference planes B1, B2. In the embodiment shown, as can be seen from the sectional views in Figures 4 and 8, each of the contact elements 1, 2 has a contact shaft 10 on the front and a mounting shaft 11 adjoining the contact shaft 10. The said surface line L1, L2 lies on a section of the mounting shaft 11 which has the largest diameter of the contact element 1, 2. Furthermore, in the embodiment shown, each contact element 1, 2 has a connection section 28 to which an electrical cable can be connected. The connection section 28 is located on the mounting shaft 11 opposite the contact shaft 10.

[0071] As shown in the figures, the printed circuit board 3 can be designed such that the defined installation space is only partially filled. The printed circuit board 3 is designed to be as large as possible to fill the defined installation space E. This applies in particular to the lateral surfaces of the contact elements 1, 2 and the reference planes B1, B2.

[0072] The electrical contact between the contact springs 8, 9 and the contact elements 1, 2 will now be explained in more detail using the sectional view in Figures 4 and 8. The first contact element 1 has a first contact surface 15, and the second contact element 2 has a second contact surface 16. The contact surfaces 15, 16 are designed here as annular surfaces that extend around the respective central axis M1, M2. The contact surfaces 15, 16 extend at an angle, here at right angles, to the respective central axis M1, M2. The first contact spring 8 is in resilient contact with the first contact surface 15, and the second contact spring 9 is in resilient contact with the second contact surface 16.The contact between the respective contact spring 8, 9 and the respective contact surface 15, 16 takes place in the direction of the respective central axis M1, M2, wherein the contact surfaces 15, 16, as mentioned, run at an angle, here at right angles, to the respective central axis M1, M2.

[0073] The embodiments of the electrical connection arrangement shown in the figures further comprise a bearing element 17. The bearing element 17 has a bearing receptacle 18 for each of the contact elements 1, 2. The contact element 1, 2 is mounted in the bearing receptacle 18. Furthermore, the bearing element 17 has further bearing receptacles for further contact elements not shown in the figures. Preferably, the contact elements 1, 2 are mechanically fixedly mounted in the bearing receptacles 18. In particular, the contact elements 1, 2 are clipped or snapped into the bearing receptacles 18. In the embodiment shown, each of the bearing receptacles has an edge region 29, which is clearly visible in Figures 3 and 7. The edge region 29 has an opening 30 into which the printed circuit board 3 projects. The contact springs 8, 9 are located in the region of the opening 30. The edge region 29 has a bearing surface 33 laterally to the opening.The contact springs 8, 9 protrude with the spring sections 13 from the opening 30 and the spring sections 13 extend from the opening 30 over the bearing surface 33. The contact element 1, 2 can strike the bearing surface 33 with the respective contact surface 15, 16 and the electrical contact between the spring section 13 and the respective contact surface 15, 16 can be established by the projection of the spring section 13.

[0074] The bearing element 17 further comprises a bearing point 19 for the printed circuit board 3, in which the printed circuit board 3 is mounted.

[0075] In the first embodiment according to Figures 1 to 4, the bearing point 19 has at least one guide pin 20. The circuit board 3 has at least one guide opening 21, wherein when the circuit board is mounted, the guide pin 20 protrudes into the guide opening 21. In the embodiment shown, the bearing point 19 has at least one locking element 22, which locks the circuit board 3 to the bearing element 17. Here, two locking elements 22 are arranged on two opposite sides of the circuit board 3. The locking elements 22 extend with a spring arm 31 along the side surface, and a locking cam 32 arranged at the free end of the spring arm 31 comes to rest on the front surface 4. The rear surface 5 of the circuit board 3 rests on the bearing element 17.

[0076] In an embodiment not shown in the figures, the guide mandrel 20 protrudes beyond the front surface 4 of the circuit board with a melting section, wherein the melting section is deformed by the action of heat in such a way that the melting section is deformed into a holding section, wherein the holding section has an extension which is greater than the diameter of the guide opening 21.

[0077] In the second embodiment according to Figures 5 to 8, the electrical connection arrangement further comprises at least one screw 24. The bearing point 19 has at least one opening 25 provided for receiving the screw 24. The circuit board 3 has at least one screw opening 26 through which the screw 24 is passed, such that the circuit board 3 is secured to the bearing element 17 with the at least one screw 24.

[0078] In both embodiments, the bearing point 19 can have a recess 27. The circuit board 3 lies with the rear surface 5 and at least partially with the side surfaces 6 in the recess 27.

[0079] Figures 4 and 8 show that the electrotechnical functional element 7 and / or the first contact spring 8 and / or the second contact spring 9 are arranged on the front surface 4 of the printed circuit board. A surface normal F, which extends at right angles from the front surface 4, runs parallel to the first central axis M1 and the second central axis M2. Furthermore, these two figures show that the spring force of the respective contact springs 8, 9 acts on the corresponding contact surface 15, 16 in a direction oriented parallel to the respective central axis M1, M2.

[0080] Further preferred features of the printed circuit board 3 will now be explained in more detail with reference to Figure 9.

[0081] The two contact springs 8, 9 are arranged on the front surface 4 of the circuit board 3. The two contact springs 8, 9 protrude from the front surface 4 of the circuit board 3. The two contact springs 8, 9 are arranged such that the contact springs 8, 9 do not extend beyond the edge of the front surface 4. This means that the contact springs 8, 9 do not extend beyond the side surfaces 6 of the circuit board 3.

[0082] The contact springs 8, 9 each have a fastening section 12, with which the contact spring 8, 9 is electrically connected to a conductor track of the circuit board 3. The fastening section 12 is preferably soldered to a conductor track on the circuit board 3. Furthermore, the contact springs 8, 9 have a spring section 13 adjoining the fastening section 12, with which the corresponding contact element 1, 2 can be electrically contacted. In the mounted state, the spring section 13 is spaced from the front surface 4 of the circuit board 3.

[0083] In the embodiment shown, the contact spring 8, 9 has a support section 14, which lies between the fastening section 12 and the aforementioned spring section 13. The support section 14 extends below the spring section 13 in the direction of the deflection of the spring section 13 and can support it from below during the contacting process of the respective contact element 1, 2, i.e. during deflection. Furthermore, the contact springs 8, 9 are arranged axially symmetrically on the front surface 4 of the circuit board 3 with respect to an axis of symmetry S, which extends perpendicular to the front surface 4 and through the center of gravity of the front surface 4. This has the advantage that the circuit board 3 can be positioned between the two contact elements 1, 2 without any orientation specifications; however, this is subject to the proviso that the circuit board 3 lies in the aforementioned installation space E.

[0084] Preferably, the contact springs 8, 9 are placed adjacent to two opposing side surfaces 6 on the front surface 4. Here, the contact springs 8, 9 are located on the side surfaces 6 that adjoin the shorter side edge of the front surface 4.
