Abstract

In an electric connector on a printed circuit board that features a connector part acted upon with relatively high electric voltage values, sparkovers between the continuing strip conductors arranged on the printed circuit board and the soldering points of the electric contacts are prevented by providing a snap-on element with several chamber in the connector part, wherein the chamber walls of this snap-on element can be inserted into slots arranged in the printed circuit board, and wherein the chambers respectively enclose the soldering point of one of the electric contacts in the connector part.

Claims

1. A connection terminal for a printed circuit board, comprising a connector part having a plurality of sockets in which a plurality of electric contacts with a mating side and a terminal side are arranged, wherein

the terminal sides of the electric contacts protrude at least partially through said printed circuit board into separate chambers of a snap-on element positioned over the terminal sides of the electric contacts, and wherein

the snap-on element is inserted into correspondingly shaped slots in the printed circuit board with the chamber walls and interlocked by hooks.

2. The connection terminal according to claim 1, wherein

the separate chambers of the snap-on element are formed by chamber walls that are moulded onto a base plate perpendicular thereto.

3. A connection terminal according to claim 1, wherein said connector part is comprised of a support plate made of an insulating material, said plurality of sockets being arranged perpendicular to said support plate.

4. A connection terminal according to claim 3, wherein said connector part is further comprised of a plurality of spacers to ensure that a minimum distance is maintained between the sockets and the printed circuit board.

5. A connection terminal according to claim 1, wherein each of said separate chambers formed by the snap-on element are open on at least on side.

6. A connection terminal for a printed circuit board, comprising a connector part in which a plurality of electric contacts with a mating side and a terminal side are arranged, wherein

the terminal sides of the electric contacts protrude at least partially through said printed circuit board into separate chambers of a snap-on element positioned over the terminal sides of the electric contacts, and wherein

the snap-on element is fixed on the printed circuit board by an interlocking device.

7. A connection terminal according to claim 6, wherein said connector part is comprised of a support plate made of an insulating material and a plurality of sockets, said plurality of sockets being arranged perpendicular to said support plate.

8. A connection terminal according to claim 7, wherein said connector part is further comprised of a plurality of spacers to ensure that a minimum distance is maintained between the sockets and the printed circuit board.
