Über das Anschlusselement, welches entweder direkt auf eine Leiterplatte gelötet oder mittels eines Pins auf eine Leiterplatte gesteckt werden kann, kann die elektrisch leitende Verbindung zwischen dem eingeführten elektrischen Leiter und der Leiterplatte hergestellt werden. Bei bekannten Leiterplattenanschlussklemmen ist das Kontaktelement in der Regel ein aufwändiges Stanz-Biege-Teil mit mehreren gegeneinander abgebogenen Flächen, welches insbesondere auch einen Anlageschenkel der Klemmfeder innerhalb des Gehäuses abstützt.Circuit board connection terminals are known with a arranged in a housing clamping spring for clamping fixing an inserted into the housing electrical conductor. Furthermore, a contact element is arranged within the housing, which is in electrically conductive connection with a connecting element arranged outside the housing. The clamping spring of the known printed circuit board connection terminals presses the electrical conductor against the contact element. About the connection element, which can be either soldered directly to a circuit board or plugged by a pin on a circuit board, the electrically conductive connection between the inserted electrical conductor and the circuit board can be made. In known printed circuit board connection terminals, the contact element is usually a complex stamped and bent part with a plurality of mutually bent surfaces, which in particular also supports an abutment leg of the clamping spring within the housing.

Das Kontaktelement wird im Wesentlichen durch eine einzige im Wesentlichen ebene Fläche gebildet, welche über ein Verbindungselement mit dem Anschlusselement verbunden ist, welches ebenfalls als im Wesentlichen ebene Fläche ausgebildet ist. Ein aufwändiges Kontaktelement mit vielen gegeneinander abgeknickten Flächen kann somit entfallen, wodurch die Leiterplattenanschlussklemme kostengünstiger herstellbar wird.The printed circuit board connection terminal according to the invention with a housing which has an inner wall and an outer wall, a clamping spring, a contact element arranged inside the housing and a connection element arranged outside the housing, wherein the contact element and the connection element are electrically conductively connected to one another, is characterized in that the contact element are arranged flat on the inner wall and the connection element lying flat against the outer wall.

Dadurch ergibt sich ein besonders platzsparender, kompakter und damit kostengünstiger Aufbau.Preferably, the contact element bears on a single side wall of the housing and / or the connection element on a single side wall of the housing, wherein preferably the contact element and the connection element bear against the same side wall but on opposite surfaces of the side wall of the housing.

This further simplifies the manufacturing process.
Das Kontaktelement und das Anschlusselement können vorteilhafterweise als Stanz-Biege-Element ausgebildet sein, wobei insbesondere weniger Biegeprozesse im Vergleich zu herkömmlichen Kontaktelementen mit daran angeordneten Anschlusselementen vonnöten sind.The contact element and the connection element can advantageously be designed as a stamped and bent element, wherein in particular fewer bending processes are required in comparison to conventional contact elements with connecting elements arranged thereon.
Eine vorteilhafte Weiterbildung der Erfindung sieht vor, dass an dem Kontaktelement eine Lasche, ein Vorsprung, eine Nase oder eine sonstige erhabene Kontur oder eine Vertiefung angeordnet ist, wodurch der elektrische Kontakt zwischen einem eingeführten elektrischen Leiter und dem Kontaktelement verbessert und die Drahtauszugskraft erhöht werden können.An advantageous development of the invention provides that on the contact element a tab, a projection, a nose or other raised contour or a recess is arranged, whereby the electrical contact between an inserted electrical conductor and the contact element can be improved and the wire extraction force can be increased ,
