Weiterhin werden Gehäuseschalen von Kommunikationsendgeräten mittels selbstfurchender Schrauben bzw. Gewindeeinsätzen und metrischen Schrauben verbunden. Hier wirkt sich im Wesentlichen die aufwendig und störungsanfällige Automatisierungstechnik negativ aus. Weiterhin nachteilig bei dieser Art der Verbindung sind der erhöhte Platzbedarf und die langen Montagezeiten.Furthermore, housing shells of communication terminals by means of self-tapping screws or thread inserts and connected to metric screws. This essentially affects the complex and fault-prone automation technology negative. Another disadvantage of this type of connection are the heightened Space requirements and long assembly times.

Aufgabe der vorliegenden Erfindung ist es daher, ein Kommunikationsgerät, bestehend aus einer oberen und einer unteren Gehäuseschale, anzugeben, bei welchem auf einfache Art und Weise die beiden Gehäuseschalen zusammengefügt werden können, und welches in einem Reparaturfall wieder einfach zu öffnen ist.Object of the present invention It is therefore, a communication device consisting of an upper and a lower housing shell, specify in which in a simple manner, the two housing shells together can be, and which in a repair case is easy to open again.

Diese Aufgabe wird für das eingangs genannte Kommunikationsendgerät erfindungsgemäß dadurch gelöst, dass die beiden Gehäuseschalen reversibel miteinander verklebt sind.This task will be for the beginning called communication terminal according to the invention thereby solved, that the two housing shells are reversibly glued together.

Durch den Einsatz der Klebetechnik können die Werkzeuge für die Schalen weniger aufwendig gestaltet werden.
