[0050] In order to better illustrate the technical effects of the present invention, the present invention provides the following specific embodiments to illustrate the above technical process:

[0051] Example 1: A cable wall penetration device suitable for vacuum environment, such as Figure 1 、 Figure 2 As shown, it is widely applicable to various vacuum chambers.
