Bei solchen Steckverbindern greift die mechanische Belastung, wie sie sich beim Ein- und Ausstecken durch die Verriegelgung mit dem Kabelstecker ergibt, unmittelbar auf das Kunststoffgehäuse, in dem der eine Verriegelungsteil der Verriegelungsvorrichtung zwischen Steckverbinder und Kabelstecker von der Deckwand her eingesteckt ist. Vom Kunststoffgehäuse aus wirkt sich die Belastung auf die leiterplattenseitigen Kontaktanschlüsse bzw. deren Lötverbindung mit der Leiterplatte aus. Eine gewisse Entlastung dieser Lötverbindung ist durch in das Kunststoffgehäuse seitlich eingesteckte Lötwinkel gegeben. Nachteilig ist nicht nur die unmittelbare Übertragung der mechanischen Belastung unmittelbar auf das Kunststoffgehäuse und die Lötverbindung sondern auch die Vielzahl der für den Aufbau des Steckverbinders zu verwendenden und damit zu montierenden Teile. Dies alles erfordert ein stabiles und wegen der Materialauswahl Kunststoff für das Gehäuse voluminöses Bauteil.Connectors of this type, as for example in Mobile phones are used and how they are used for example in DE 195 00 102 A1 are supposed to be in ever smaller versions offered, however, must always have the same powers at Can endure insertion and removal of a cable connector. at such connectors engages the mechanical load, such as when locking and unplugging the cable connector results directly on the Plastic housing in which the one locking part of the Locking device between the connector and Cable connector is inserted from the top wall. from Plastic case affects the load on the PCB-side contact connections or their Solder connection to the circuit board. A certain one Relief of this solder joint is through in that Plastic housing on the side inserted soldering angle. A disadvantage is not only the direct transmission of the mechanical load directly on the plastic housing and the solder connection but also the multitude of for the Structure of the connector to be used and therefore too assembling parts. All of this requires a stable and because of the choice of material plastic for the housing voluminous component.
