Embodiment Construction

[0055] figure 1 A hollow tube 1 is shown on which a flange 2 is arranged at one of its two ends, said flange substantially corresponding to the flange. It can also be seen that the hollow tube 1 is provided with a thread 8 on its outer side. Thread 8 extends from flange 2 to the end of hollow tube 1 opposite flange 2 .

[0056] Furthermore, a sealing element 11 can be seen which has a bore 12 through which the hollow tube 1 is guided such that the sealing element 11 bears against the flange 2 of the hollow tube 1 . When a sufficiently high pressing force is applied, the sealing element 11, which preferably comprises polyethylene or preferably consists of polyethylene, melts, thereby compensating for unevenness between the flange 2 and the element performing the compression. The element presses the high barrier film 3 against the flange 2 from the other side.

[0057] Furthermore, the hollow tube is guided through the hole 4 of the high-barrier membrane 3 by means of the end...

Abstract

The invention relates to a device for conducting electrical conductors through a high barrier film in a vacuum-tight manner. The device comprises: a hollow tube 1 having a flange 2 protruding therefrom; a high barrier film 3 having a through-hole 4 through which the hollow tube 1 extends hole; and a pressing element 5, which is arranged on the side of the high barrier film 3 away from the flange 2 and presses the high barrier film 3 toward the flange 2, wherein the The high barrier film 3 is arranged between the flange 2 of the hollow tube 1 and the pressing element 5 . Furthermore, the device is characterized in that electrical leads run in the hollow tube 1 , which lead from one side of the high-barrier film 3 towards the other side of the high-barrier film, and in which A sealing compound is present in the hollow tube to seal the hollow tube 1 in a vacuum-tight manner. It is thereby possible to provide cost-effective electrical feedthroughs, via which higher powers can also be transmitted in a diffusion-tight manner through the high-barrier film with low losses.

Description

technical field [0001] The invention relates to a device for the vacuum-tight introduction of electrical lines through a high-barrier film and a method for producing a vacuum-tight lead-through by means of the device according to the invention. Background technique [0002] Vacuum insulation is usually present in cooling or freezing plants in order to achieve sufficient thermal insulation of the plant. [0003] In order to produce such vacuum insulation, it is necessary to produce a high-barrier film which surrounds a filling material which gives the vacuum insulation a corresponding shape and stability and at the same time prevents the walls of the vacuum insulation from directly against each other in the evacuated state. The use of high-barrier films is an inexpensive variant in order to maintain the vacuum levels required in vacuum insulation installations for many years. In order to provide a sufficient service life for such vacuum-insulated containers, the area surrou...
