Embodiment Construction

[0166] figure 1 An isometric front view of a leak-tightness testing device according to the invention, here comprising eight measuring cells, is shown.

[0167] Accordingly, the leak-tightness testing device has a surrounding, box-like housing 2 , which delimits an interior space in which a plurality of measuring units and other instruments are arranged.

[0168] Each measuring unit comprises a substantially hollow-cylindrical adapter 4 which, in the mounted state, protrudes with its insertion opening 4a, which is open to the front, from a corresponding opening in the housing 2, so that the test body or test piece can be The open test end is inserted into said insertion opening 4a. Each adapter 4 is connected to a valve 8 via a line piece 6 arranged at the rear end of the adapter 4 . Furthermore, connected to the line part 6 is a pressure sensor 10 which detects the line pressure and the system pressure in the line and test body. Finally, the valve is connected to a piston ...

Abstract

To perform a particularly simple and quick leak-tightness test on a test subject for leak-tightness, the invention proposes a testing method and a leak-tightness testing device designed for carrying out the method. The method is characterised in that the test subject is inserted with an optionally stripped test end into an adapter 4, that the adapter 4 is sealed off with respect to the surroundings, that a test pressure is applied to the test subject, and that a leakage rate is determined.

Description

technical field [0001] The invention relates to a testing method for checking the tightness of cables and a device for carrying out the testing method. Background technique [0002] Here, the term "cable" is to be understood as a line consisting of a plurality of pipelines, which may generally but not necessarily have a common jacket or cable jacket. A “pipeline” is to be understood as meaning the cable cores of a cable which are insulated separately from one another, so that a group of parallel pipelines can likewise be represented as one cable. Wires or strands made of electrically conductive material are referred to as "cable cores". A "cable connection part" is a connection between a pipeline (or cable core) of a first cable and a pipeline of a second cable or other cables and / or contact with each other and / or by means of other components. [0003] In order to connect several cables or several lines of a cable to other lines of the same cable or to other lines of other...
