DETAILED DESCRIPTION

(6) The figures illustrate in part simplified schematic views. In part, identical reference numerals are used for similar but possibly not identical elements. Different views of similar elements may be scaled differently.

(7) FIGS. 1a-b illustrate a printed circuit board connector 1.

(8) The printed circuit board connector 1 is configured as a pin contact with a pin axis A indicated in FIG. 1b and is embodied from an at least slightly reversibly deformable, electrically conductive material. In the present case, the printed circuit board connector 1 is embodied from metal but it is also feasible to use another material by way of example an electrically conductive or conductively coated synthetic material.

(9) The printed circuit board connector 1 comprises a connection-side end 11 and a mating-side end 12. It comprises a printed circuit board connection region 111 on its connection-side end 11. Lying opposite, it comprises a mating region 122 that tapers toward the mating-side end 12. The printed circuit board connector 1 comprises between the printed circuit board connection region 111 and the mating region 122 a pin-shaped connecting section 10 whose region is graphically emphasized in FIG. 1b with the aid of a curly bracket. The printed circuit board connector 1 comprises between the connecting section 10 and the printed circuit board connection region 111 a cylindrical, circumferential collar 13.

(10) The printed circuit board connector 1 comprises two slits S1, S2, namely a first slit S1 and a second slit S2 that cross in the pin axis at a right angle and end in the connecting section 10, said slits commencing at the mating-side end 12 and extending in the direction of the printed circuit board connection region 111 along the pin axis A. As a consequence, four identical segments 14 that are particularly clearly visible in FIG. 1a are formed in the printed circuit board connector 1. Each of the four segments 14 comprises at the mating-side end 12 of the printed circuit board connector 1 a free-standing end that for the sake of clarity are not provided with separate reference numerals. The segments 14 face with their free-standing ends jointly in the mating direction of the printed circuit board connector 1.

(11) FIG. 1c illustrates a cross-sectional view of the printed circuit board connector 1 with two printed circuit boards 21, 22, namely a first printed circuit board 21 and a second printed circuit board 22, said printed circuit boards being connected by means of said printed circuit board connector. The two printed circuit boards 21, 22 have in each case multiple through-going contact openings 210, 220.

(12) On the one hand, the printed circuit board connector 1 is inserted with its printed circuit board connection region 111 through one of the through-going contact openings 210 of the first printed circuit board 21 and soldered to the contact region 228 (shown in FIG. 2c) that is located thereon also on the inner face. Simultaneously, it is placed with its collar 13 on the second printed circuit board 22.

(13) Furthermore, it is clearly apparent that on the other hand, so as to electrically connect the two printed circuit boards 21, 22, the printed circuit board connector 1 has been guided beforehand with its mating region 122 through the through-going contact opening 220 of the second printed circuit board 22 and now engages therethrough in an electrically contacting manner with a part of its connecting section 10, said part being adjacent to the mating region 122. In so doing, as the mating region 122 is inserted into the through-going contact opening 220 the respective free-standing ends of the four segments 14 are to move toward one another whilst the segments 14 deform in a slightly elastic manner. As a consequence, the segments 14 generate a corresponding counterforce with which they press against a contact material that is arranged in the through-going opening 220 and is a component of the contact region 228.

(14) In this manner, a mechanical attachment arrangement and an electrical contacting arrangement is created between the two printed circuit boards 21, 22, wherein the electrical contacting arrangement prints a particularly high conductivity value as a result of the corresponding high contact force. The mechanical attachment arrangement has simultaneously the desired tolerance values.

(15) By virtue of this deformation, in the plugged-in state the four segments 14 are oriented with their free-standing ends slightly toward one another. Consequently, in the plugged-in state the printed circuit board connector 1 tapers slightly toward its mating region 12. Conversely, in the plugged-in state it widens slightly in the direction of its printed circuit board connection region 111.

(16) The second printed circuit board 22 may therefore be inserted within a predetermined tolerance range slightly deeper, but ideally not to any depth, onto the connecting region 10 of the printed circuit board connector 1. In the reverse direction, i.e. in the mating direction, the second printed circuit board 22 may also be moved away from it and/or completely pulled off it. In other words, the printed circuit board connector 1 may be inserted with its connecting region 10 still somewhat deeper into the through-going contact opening 220 of the second printed circuit board 22 or pulled back somewhat further out. As the printed circuit board connector 1 is inserted deeper in, the segments 14 move with their free-standing ends in a somewhat slightly more elastic manner with respect to one another. As the printed circuit board connector 1 is pulled out slightly, said segments move back in a somewhat more intense manner away from one another. As a consequence, a tolerance region is created within which the plug-in depth may vary. Consequently, a distance D between the two printed circuit boards 21, 22 may also vary within the thereby predetermined tolerance range while simultaneously the electrical contacting arrangement is ensured for high current strengths, for example >10 amps.

(17) FIGS. 2a and 2b illustrate an oblique view and a lateral view of the two mutually parallel printed circuit boards 21, 22 with conductor tracks 213, 223 located thereon. The two printed circuit boards 21, 22 are mechanically and electrically connected to one another via multiple printed circuit board connectors 1, as explained above in detail with reference to the example of a printed circuit board connector 1. The electrical connection is thereby formed between two conductor tracks 213, 223 respectively.

(18) FIG. 2c illustrates a plan view of this arrangement. It is clearly apparent how the printed circuit board connector 1 engages through the through-going contact opening 220 of the second printed circuit board 22 and protrudes with its mating-side end 12 out of the second printed circuit board 22, as a result of which it elastically contacts the corresponding conductor track 223 at the contact region 228 thereof.

(19) Even if different aspects or features of the invention are illustrated in the figures in each case in combination, it is obvious to the person skilled in the art—unless otherwise indicated—that the illustrated and discussed combinations are not the only possible combinations. In particular, units or feature complexes of different exemplary embodiments that correspond to one another may be exchanged with one another.
