Description of the Invention: [Technical Field] The present invention relates to a method for inserting a plurality of communication cables into a communication device box, such as a terminal box, a pre-stubbed terminal, an optical network terminal = or 5 The introduction device in other junction boxes, wherein the communication cable comprises an optical fiber 1 copper wire or a micro coaxial cable ^ [Prior Art] "Communication of 5 cables is common, and is widely used for network data distribution. 10 Although the ability to transmit data over optical cables continues to increase, the use of fiber optic cables in communication networks is growing rapidly, but most cables are also electrically conductive cables (typically copper cables). 'Because the communication cable is routed according to the data network, it is necessary to open the cable periodically so that one or more of the two lines 15 can be connected, so that the data can be distributed to other communication networks. In a cable or branch. At each point where the communication cable is opened, it is desirable to provide a communication device box for protecting the exposed internal portion of the cable. Cables may be further distributed until the network reaches individual users' homes, businesses, offices, and so on. 20 Many traditional communication equipment boxes use glue or rubber grommet to introduce cables into the equipment box. Some cement and grommet components can accommodate more than one cable. Optionally, it is also known to introduce a cable onto the cable before it is installed in the cassette of the communication device box. However, typically these lead-in devices accommodate only one cable in each turn of the equipment box. A conventional introduction device is described in the U.S. Patent No. 5,2010, 051, issued to the U.S. Patent Application Serial No. 60/895,233, the entire disclosure of which is incorporated herein by reference. . 5
