Abstract

In an electric connector on a printed circuit board (20) that features a connector part (1) acted upon with relatively high electric voltage values, sparkovers between the continuing strip conductors arranged on the printed circuit board and the soldering points (22) of the electric contacts (8) are prevented by providing a snap-on element (10) with several chambers (13) in the connector part (1), wherein the chamber walls (12) of this snap-on element can be inserted into slots (23) arranged in the printed circuit board (20), 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 and an insulating housing of which features several sockets in which electric contacts with a mating side and a terminal side are arranged, wherein

the terminal sides of the electric contacts protrude at least partially into separate chambers of a snap-on element that can be positioned over the sockets of the connector part from the terminal side.

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 connector part according to claim 1, wherein

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

4. The connector part according to claim 1, wherein

the snap-on element of the connector part can be fixed on the printed circuit board by an interlocking device.
