Abstract

The invention discloses a cable penetration sealing device and a production method thereof, and relates to a structure improvement of the cable penetration sealing device. The invention provides the cable penetration sealing device having the advantages of simple structure, unified specification and batch production. The cable penetration sealing device comprises a frame body, and is characterized in that sealing modules with through holes are arranged in the frame body in a layering manner, wherein spacing plates are arranged between the layers; gaps between the sealing module and the frame body and the spacing plates are filled by blind plug modules; and a pressing block is arranged above the uppermost layer of the spacing plates.

Description

technical field [0001] The present invention relates to the improvement of the structure of the cable penetration sealing device. Background technique [0002] The existing cable penetration seals are all designed according to the user's needs. Such a sealing method is relatively rigid and it is difficult to change its structure. In addition, due to the different specific conditions of users, the structure of the cable penetration seal cannot be unified, let alone mass production. Time-consuming and labor-intensive. Contents of the invention [0003] The present invention aims at the above problems, and provides a cable penetration sealing device with simple structure, uniform specifications and mass production. [0004] In order to achieve the above-mentioned purpose of the present invention, the present invention adopts the following technical scheme. A cable penetration sealing device of the present invention includes a frame body, and its structural points are layered...
