Abstract

A printed circuit board-and-plug arrangement comprises a printed circuit board from which at least one electrically conductive contact lug which is electrically connected to at least one conductor track of the printed circuit board protrudes, and a plug housing composed of insulating material, which plug housing has at least one opening, wherein a metal strip or metal wire is embedded in the insulating material so that at least a portion of the metal strip or the metal wire protrudes into the opening, wherein the plug housing is releasably connected to the printed circuit board so that the contact lug is inserted into the opening and thereby comes into contact with the portion, wherein the longitudinal direction of the contact lug and the longitudinal direction of the portion run perpendicularly in relation to one another.

First claim

The invention claimed is:

1 . A method of producing a printed circuit board-and-plug arrangement, comprising:
a printed circuit board from which at least one electrically conductive contact lug which is electrically connected to at least one conductor track of the printed circuit board protrudes, and comprising a plug housing composed of insulating material, which plug housing has at least one opening, wherein a metal strip or metal wire is embedded in the insulating material so that at least a portion of the metal strip or the metal wire protrudes into the opening, wherein the plug housing is releasably connected to the printed circuit board so that the contact lug is inserted into the opening and thereby comes into contact with the portion, wherein longitudinal direction of the contact lug and longitudinal direction of the portion run perpendicularly in relation to one another.

2 . The method as claimed in claim 1 , wherein the portion is embedded in the insulating material of the plug housing only on one side and is elastically bent by the contact lug protruding into the opening.

3 . The method as claimed in claim 1 , wherein the portion is embedded in the insulating material of the plug housing on both sides and is elastically deformed by the contact lug protruding into the opening.

4 . The method as claimed in claim 1 , wherein the portion is embedded in the insulating material of the plug housing on both sides and is in contact with a bottom of the opening and the contact lug protruding into the opening is formed with a spring element which presses the contact lug against the portion.

5 . The method as claimed in claim 1 , wherein the printed circuit board is provided with an insulating casing.

6 . The method as claimed in claim 1 , wherein that end of the contact lug which comes into contact with the portion is structured.

7 . The method as claimed in claim 6 , wherein the end of the contact lug has teeth or is pointed or rounded.

8 . The method as claimed in claim 7 , wherein the portion has a mating structure which interacts with the structure.

9 . The method for producing a printed circuit board-and-plug arrangement as claimed in claim 1 , wherein the plug housing is releasably connected to the printed circuit board by means of a snap-action connection.

10 . The method as claimed in claim 4 ,
wherein the printed circuit board is provided with an insulating casing, wherein that end of the contact lug which comes into contact with the portion is structured, wherein the end of the contact lug has teeth or is pointed or rounded, wherein the portion has a mating structure which interacts with the structure, and wherein the plug housing is releasably connected to the printed circuit board by means of a snap-action connection.

11 . A printed circuit board-and-plug arrangement, comprising:
a printed circuit board from which at least one electrically conductive contact lug which is electrically connected to at least one conductor track of the printed circuit board protrudes, and comprising a plug housing composed of insulating material, which plug housing has at least one opening, wherein a metal strip or metal wire is embedded in the insulating material so that at least a portion of the metal strip or the metal wire protrudes into the opening, wherein the plug housing is releasably connected to the printed circuit board so that the contact lug is inserted into the opening and thereby comes into contact with the portion, wherein longitudinal direction of the contact lug and longitudinal direction of the portion run perpendicularly in relation to one another.

12 . The arrangement as claimed in claim 11 , wherein the portion is embedded in the insulating material of the plug housing only on one side and is elastically bent by the contact lug protruding into the opening.

13 . The arrangement as claimed in claim 11 , wherein the portion is embedded in the insulating material of the plug housing on both sides and is elastically deformed by the contact lug protruding into the opening.

14 . The arrangement as claimed in claim 11 ,
wherein the portion is embedded in the insulating material of the plug housing on both sides and is in contact with a bottom of the opening and the contact lug protruding into the opening is formed with a spring element which presses the contact lug against the portion.

15 . The arrangement as claimed in claim 14 ,
wherein the printed circuit board is provided with an insulating casing, wherein that end of the contact lug which comes into contact with the portion is structured, wherein the end of the contact lug has teeth or is pointed or rounded, wherein the portion has a mating structure which interacts with the structure, and wherein the plug housing is releasably connected to the printed circuit board by means of a snap-action connection.

16 . The arrangement as claimed in claim 11 ,
wherein the printed circuit board is provided with an insulating casing.

17 . The arrangement as claimed in claim 11 ,
wherein that end of the contact lug which comes into contact with the portion is structured.

18 . The arrangement as claimed in claim 17 ,
wherein the end of the contact lug has teeth or is pointed or rounded.

19 . The arrangement as claimed in claim 18 ,
wherein the portion has a mating structure which interacts with the structure.

20 . The arrangement as claimed in claim 11 ,
wherein the plug housing is releasably connected to the printed circuit board by means of a snap-action connection.
