DETAILED DESCRIPTION

[0027] FIG. 1 shows a sectional view of an electronics housing 10 with two housing parts 1, 2. The housing part 1 arranged at the bottom in FIG. 1 is cut off at the bottom and represents, for example, a housing body mounted on a drive train component, such as a transmission, in a motor vehicle.

[0028] The housing part 2 arranged at the top in FIG. 1 is a housing cover with a plug connection region 13. The electronics housing 10 can be connected to a further vehicle component (not shown in FIG. 1) via the plug connection region 13, which is used, for example, to insert a corresponding plug.

[0029] A circuit board 3 is arranged in the electronics housing 10. The circuit board 3 is combined with a press-fit body 4. A press-fit connection 5 is inserted into the circuit board 3 in a manner known per se. The press-fit connection 5 is one of multiple press-fit connections shown in FIG. 1 arranged side by side in a row extending perpendicular to the drawing plane of FIG. 1.

[0030] The press-fit connection 5 is arranged in a horizontal direction in FIG. 1 between two guide pins 6, 7 which extend from the press-fit body 4 in FIG. 1 in a vertical direction parallel to one another from bottom to top. The guide pins are essentially in the form of straight circular cylinders.

[0031] The press-fit connection 5 is arranged approximately in the middle of the two guide pins 6, 7. As can be seen in FIG. 1, the plug connection region 13 is arranged above the guide pins 6, 7 and above the press-fit connection 5. The plug connection region 13 on the housing cover 2 is arranged centrally between two parallel longitudinal axes of the guide pins 6, 7.

[0032] The guide pins 6, 7 are integrally connected to the press-fit body 4 and extend through circuit board through-holes 8, 9 in the circuit board 3. On a side facing away from the guide pins 6, 7, the press-fit body 4 has an assembly protrusion 11 projecting downwards in FIG. 1, which engages in an assembly recess 12 provided for this purpose in the housing body 1.

[0033] The housing cover 2, the circuit board 3 and the press-fit body 4 are mounted by means of screws 14, 15 screwed into threaded holes 24, 25 in the housing body 1, namely in FIG. 1 from above. The housing body 1 includes two deepenings 27, 28 between the assembly recess 12 and the threaded holes 24, 25, which are designed, for example, as threaded holes, for corresponding extensions of the press-fit body 4.

[0034] The guide pins 6, 7 engage above the circuit board 3 in guide recesses 16, 17 provided for this purpose in the housing cover 2. Particularly advantageously, only the two circuit board through-holes 8, 9 in the circuit board 3 are required for the two guide pins 6, 7. Advantageously, no guide pins are required on the housing cover 2.

[0035] The two guide pins 6, 7 are used to effectively position the press-fit body 4, the housing cover 2 and the circuit board 3 arranged between them with the circuit board through-holes 8, 9. The mounting relative to one another is implemented by means of screws 14, 15.

[0036] For this purpose, the housing cover 2 is equipped with a mounting flange 26, which has two mounting through-holes 18, 19 for the screws 14, 15. Coaxial mounting through-holes 20, 21; 22, 23 are provided in the circuit board 3 and in the press-fit body 4 for the mounting screws 14, 15.

[0037] The guide pins 6, 7 are advantageously used to first position the press-fit body 4 relative to the circuit board 3 during assembly, wherein the press-fit connection 5 or multiple press-fit connections can be made simultaneously. Advantageously, the press-fit body 4 can be positioned relative to the housing body 1 with the assembly protrusion 11 in the assembly recess 12 before this operation.

[0038] The housing cover 2 can then be positioned using the guide pins 6, 7 and fixed in place using the screws 14, 15. At the same time, the circuit board 3 and the press-fit body 4 are fixed between the two housing parts 1, 2.

[0039] In FIG. 2, it can be seen that a second press-fit body 34 is arranged in the electronics housing 10 in addition to the press-fit body 4, which is also referred to as the first press-fit body 4. The second press-fit body 34 is used to represent a second press-fit connection 35, which is joined to the circuit board 3 from above in FIG. 2.

[0040] The second press-fit body 34 is connected to the plug connection region 13 via connection lines 36. In this regard, the second press-fit body 34 is mounted to the housing part 2 of the electronics housing 10. Advantageously, the guide pins 6, 7 of the first press-fit body 4 can be used for guiding of the second press-fit body 34 during assembly.

[0041] In FIG. 3, a partially transparent view of the housing part 2 illustrates how the guide pins 6, 7 project upward from the circuit board 3. When assembling the electronics housing 10, the housing part 2 is pre-assembled with the second press-fit body 34 on the circuit board 3 to make the second press-fit connection 35.

[0042] The first press-fit connection 5 has advantageously already been mounted on the circuit board 3 from below with the first press-fit body 4 in FIG. 2. The housing part 2 is then advantageously assembled together with the already pre-assembled press-fit bodies 4, 5 and the circuit board 3 with the housing part 1 to complete the electronics housing 10.
