DETAILED DESCRIPTION

[0032] The disclosure is explained in more detail in the following with reference to FIGS. 1 to 5, wherein use of the same reference numerals in the figures indicates the same structural and/or functional features.

[0033] FIGS. 1 and 2 show two different exemplary embodiments of a printed circuit board corner connector 1.

[0034] The respective printed circuit board corner connector 1 is designed for connecting a first printed circuit board LP to a second printed circuit board LP comprising a substantially flat contact body 10. This contact body 10 contains a respective first connection end 20 in the form of a press-on connector for connecting to one of the printed circuit boards. Two soldering pins 30 protrude laterally from the lateral surface 11 of the respective contact body 10, which soldering pins are formed for producing a soldered connection with the other printed circuit board. The soldering pins 30 may be round, oval, squared, or star-shaped or provided with solder flank structures, e.g. with external bars.

[0035] As can be easily seen in FIG. 4, two depressions 31 are indicated in lateral surface 12 opposite lateral surface 11, which depressions are formed on the other side in corresponding positions as relates to the soldering pins 30. The soldering pins 30 in this case integrally protrude from the central region B of the flat contact body 10. As can be seen in FIGS. 1 and 2, the soldering pins 30 protrude in the manner of a crater from a central region of the flat contact body 10 and have a substantially cylindrical casing surface.

[0036] In the exemplary embodiment of FIG. 1, the flat contact body 10 has a substantially rectangular basic shape with rounded corners 14.

[0037] In the exemplary embodiment of FIG. 2, the flat contact body 10 has a substantially rectangular basic shape, wherein respectively lateral overhangs or widenings 22 are provided in the region of the soldering pins 20, and that is with a somewhat cylindrically shaped side wall 23.

[0038] FIG. 5 shows a board connection assembly with a plurality of 3 printed circuit board corner connectors 1 mounted on a printed circuit board LP. The board connection assembly comprises a sealing overmold U, which seals off the circuit board corner connector on a flat bar section SA thereof. The printed circuit board corner connectors 1 are pressed, with the press-in section thereof, into the press-in zones EZ in the printed circuit board LP. In addition, assembly aids M are provided with which the overmold U is mounted on the printed circuit board, preferably with mechanical support.

[0039] The disclosure is not limited in its design to the aforementioned preferred exemplary embodiments. Rather, a number of variants is conceivable, which would make use of the solution shown even with essentially different designs.
