6. cable sealing ring is inserted in the interior step through-hole of bottom plate, connection pressing plate forms cable fixed plate with bottom plate and fixed
Cable；
7. liquid sealant encapsulating solidification, is completed from the cable inlet port injection on the inside of closed container.
Because the external diameter of pressing plate is identical with the mounting surface external diameter on bottom plate, the installation of bottom plate and second flange face is not influenceed,
And bottom plate is fixed, be advantageous to cable sealing ring and be accurately pushed into bottom plate outer step through hole.But because liquid sealant is in encapsulating cylinder
Be connected with closed container installation after inject, be only applicable to closed container cable inlet port be located at container lower section when use.When
When cable inlet port is located at container side, sealing adaptor bend pipe can be set in container port（Such as Fig. 6）Using of the invention real
Apply example 1；Can be by the bottom plate enlarged outside diameter of the cable fixed plate of the present invention, increase when cable inlet port is located above container
Sealing surface and seal groove, cable fixed plate are reversely connected with closed container port, and encapsulating cylinder only has the second method being connected with bottom plate
Orchid, the port of liquid sealant never sealing flange are injected to form cable seal penetration piece（Concrete structure such as Fig. 7）.
The first half sets in the embodiment of the present invention 1, the second half sets and insulated screw are made up of insulation polyethylene material；Encapsulating
Cylinder, bottom plate and pressing plate are made using stainless steel material.
