DETAILED DESCRIPTION OF THE DRAWINGS

[0053] FIG. 1 shows a soldering contact 2 according to the invention. The soldering contact 2 has a contact region 4 for contacting a plug connector contact. The soldering contact 2 has SMD soldering surfaces 6, 8, 10, 12, which are configured for soldering to a printed circuit board and or for materially bonded connection to a soldering pin.

[0054] The soldering contact 2 also has recesses 14, 16, 18, which are each configured to receive a soldering pin.

[0055] In this case, the soldering contact 2 is composed of an electrically conductive metallic material. The recesses 14, 16, 18 have been produced by punch-outs.

[0056] The soldering contact 2 according to FIG. 1 may be used as an SMD soldering contact and fitted, for example, in a contact module such as a contact socket, a base strip or the like. Such a base strip or contact socket, having one or more soldering contacts 2, can in each case be soldered to a printed circuit board by means of the SMD soldering surfaces 6, 8, 10, 12.

[0057] FIG. 2 shows a further development of a soldering contact 20 according to the invention. In order to avoid repetitions, only the differences between the embodiment variants described below and the exemplary embodiment described above are discussed, and features that are the same are denoted by the same references.

[0058] The soldering contact 20 according to FIG. 2 has a soldering pin 22, which has been received in the recess 18 and connected in a materially bonded manner to the surfaces 24, 26 delimiting the recess 18.

[0059] A longitudinal extent of the soldering pin 22 along its longitudinal extent L is oriented transversely in relation to an insertion direction R of the plug connector contact to be connected. In this case, an angle of 90° is provided between the insertion direction R and the longitudinal axis L.

[0060] FIG. 3 shows the fully assembled state of the soldering contact 20 relative to a printed circuit board 28. According to this, the insertion direction R has an orientation that is substantially parallel to a face plane P spanned by the printed circuit board 28.

[0061] In other words, a plug connector contact 30 is then accordingly pushed onto the contact region 4 of the soldering contact 20, parallel to a face plane spanned by the printed circuit board 28. The soldering contact 20 in this case is accommodated in a plastic housing 32 of a contact module, such as a contact socket or base strip.

[0062] The contact region 4 has two projecting webs 34, 36, the longitudinal extent of which has an orientation substantially parallel to the insertion direction R. Accordingly, the longitudinal extent of the soldering pin 22 along the longitudinal axis L is likewise oriented transversely in relation to the longitudinal extent of the webs 34, 36. In this case, the webs 34, 36 form spring arms, each having end contact lugs 38, 40, in the region of which a local constriction is formed.

[0063] FIG. 4 shows a further variant of a soldering contact 42, which differs from the previously described exemplary embodiment of FIGS. 2 and 3 in that there is now a soldering pin 44 received in the recess 16.

[0064] According to this, according to the variant of FIG. 4, a longitudinal extent of the soldering pin 44 along its longitudinal axis L has an orientation parallel to an insertion direction R of a plug connector contact, such that the longitudinal extent of the soldering pin 44 along the longitudinal axis L includes an angle of 0° relative to the insertion direction R.

[0065] FIG. 5 shows the fully assembled state of such a soldering contact 42, which is accommodated in a plastic housing 32. Owing to the arrangement of the soldering contact 42 in the recess 16, an insertion direction R is now oriented perpendicularly in relation to the face plane P spanned by the printed circuit board 28.

[0066] FIG. 6 shows a further variant of a soldering contact 46, which differs from the previously described exemplary embodiment in an SMD soldering surface 48, which is inclined at an angle of 45° relative to the insertion direction.

[0067] A soldering pin 50 is welded to the SMD soldering surface 48, which is inclined at the angle of 45°. This accordingly allows an arrangement of a base strip or contact socket that renders possible an insertion direction R of a plug connector contact, relative to a printed circuit board, that is inclined at an angle of 45° relative to a face plane P of a printed circuit board.

[0068] FIG. 7 shows a further variant of a soldering contact 52, which has a soldering pin 54 that is received in the recess 18, and a soldering pin 56 that is welded to the SMD soldering surface 10. Two connections to a printed circuit board can thus be produced for the soldering contact 52.

[0069] FIG. 8 shows a soldering contact 58 having an arrangement of two soldering pins 60, 62 that allow an insertion direction R oriented perpendicularly in relation to the face plane P of a printed circuit board.

[0070] FIG. 9 shows a further variant of a soldering contact 64, having a soldering pin 66 received in the recess 16, the soldering pin 66 in this case being angled by 90° in order to enable an insertion direction R having an orientation parallel to a face plane P of a printed circuit board when the soldering pin 66 is fitted in the recess 16.
