Positioning element
The present invention relates to a part of a housing producible by means of a mold and having at least one positioning element, which is arranged on one of the inner sides of the part of the housing. The positioning element is produced from the same mold half of the mold of the part of the housing used to produce one of the external sides of the part of the housing. The positioning element is also a component of this part of the housing, wherein the positioning element forms at least one reference surface. The positioning element is thereby produced from the same mold half used to produce that part of the housing to which another part of the housing, or a part to be arranged on and/or inside the housing, is to be added or attached by means of the positioning element. The tolerance during assembly is thus primarily determined by the positioning element. The positioning element and the reference surfaces assigned or belonging thereto define the position of the other part of the housing or of the part to be arranged on and/or inside the housing in its position to said part of the housing. Thus the accuracy of the position is determined only by one half of a mold and no longer by the other mold half. This results in the desired arrangement with more exact fit.

characterized in that a printed circuit board having plug contacts is attached to a part of a housing that is joined to least one other part of a housing and forms a housing part, wherein the printed circuit board demonstrates at least one through-hole which corresponds to the at least one reference surface of the at least one positioning element in such a manner that one surface side of the printed circuit board can come to rest on the at least one reference surface of the at least one positioning element with positive fit in the mounted state; and
further characterized in that the printed circuit board having the plug contacts is attached to one of the part of the housing and the other part of the housing that is assembled with the part of the housing.

3. The part of a housing according to claim 1 , characterized in that the mold is an injection mold.
4. The part of a housing according to claim 1 , characterized in that the at least one positioning element is a pin, a peg, a bolt, or a geometric shape projecting over the base from the inner side of the part of the housing nearly perpendicularly off from the base of the inner side of the part of the housing.
5. The part of a housing according to claim 4 , characterized in that the pin, the peg, the bolt, or the geometric shape projecting over the base from the inner side of the part of the housing nearly perpendicularly off from the base of the inner side of the part of the housing demonstrates at least one detent on its side facing away from the base.
6. The part of a housing according to claim 1 , characterized in that the part of the housing is joined to the least one other part of the housing and forms a housing part which is assembled into a housing with other housing parts, and wherein the assembled housing nearly encloses the interior space being formed so that it is watertight.
7. The part of a housing according to claim 6 , characterized in that the other part of the housing demonstrates an aperture corresponding to the at least one positioning element so that the at least one positioning element protrudes through the at least one other part of the housing when the part of the housing is assembled with the at least one other part of the housing.
8. The part of a housing according to claim 6 , characterized in that the at least one other part of the housing demonstrates at least one plug basket.
9. The part of a housing according to claim 1 , characterized in that the at least one reference surface of the at least one positioning element can limit the position of the printed circuited board relative to the inner side of the part of the housing.
10. The part of a housing according to claim 1 , characterized in that the at least one positioning element can fix the printed circuit board on the part of the housing by means of at least one detent.
11. A part of a housing comprising:
a base having an external side and an opposed inner side; and
a positioning element that extends from the inner side of the base and is a single part with the base, the positioning element including a reference surface;
wherein the base and the positioning element are produced in a multi-part mold, and wherein the positioning element and the reference surface are produced as a component of the base and in the same mold half as the external side of the base;
characterized in that a circuit board having plug contacts is attached to a part of the housing that is joined to least one other part of a housing and forms a housing part, wherein the circuit board demonstrates at least one through-hole which corresponds to the at least one reference surface of the at least one positioning element in such a manner that one surface side of the circuit board can come to rest on the at least one reference surface of the at least one positioning element with positive fit in the mounted state; and
further characterized in that the printed circuit board having the plug contacts is attached to one of the part of the housing and the other part of the housing that is assembled with the part of the housing.
12. The part of a housing of claim 11 , further including a second positioning element that extends from the inner side of the base and includes a second reference surface, wherein the base and the second positioning element are produced in a multi-part mold, and wherein the second positioning element and the second reference surface are produced as a component of the base and in the same mold half as the external side of the base.
13. The part of a housing of claim 12 , wherein the second reference surface is in the same plane as the first reference surface.
