Moreover, there were drawbacks such as the fact that it was impossible or extremely difficult to disassemble the seal portion for reconnection. Furthermore, there are construction methods that use non-adhesive sealing materials to compensate for these drawbacks of conventional methods, but as the sealing materials flow and deform, the airtightness of the connections deteriorates over a long period of time, causing gas leakage. There were inconveniences such as unreliability such as

つて上記接続用函体１８内は気密に保持される。 In the communication cable connection section configured in this manner, when a gas for gas retention such as air or nitrogen gas is pressurized and sealed into the cable 1, the outer sheath 4 is peeled off and the exposed conductor connection section 3 is passed through the connection section 3. The space 23 is also filled with the gas, and the inside of the connection case 18 is pressurized to the same pressure as the inside of the cable 1. Then, the gas pressure within the connection box 18 acts to push and expand the end plate 5 from within the grooves 14 in the inner and outer circumferential directions. As a result, the end plate 5 expands toward the outer and inner circumferences, so that the protrusions 8..., 16... formed on the inner and outer circumferential surfaces of the end plate 5 are connected to the cable 1 through the sealing materials 10, 17, respectively. outer covering 4
The connecting case 18 is tightly adhered to the inner circumferential surface of the connecting case 18, so that the inside of the connecting case 18 is kept airtight.

なものとすることが可能となる。 However, according to such a connection part of a communication cable, the gas pressure inside the connection case 18 is reduced to the groove part 1.
4... Since the end plate 5 is expanded from inside in the inner and outer circumferential directions to airtightly seal the inside of the connection case 18, airtightness is maintained even if the sealing material flows and deforms on the outer sheath 4 of the cable 1. can do. In addition, since the pillars 15 are provided between the grooves 14, even if the radial force is applied to the end plate 5 due to bending of the cable 1, for example, and the area around the grooves 14 is compressed, the grooves 14 There is no fear that ... will become blocked. Further, since the annular protrusions 8, 16, etc. are provided on the inner and outer circumferential surfaces of the end plate 5, the sealing effect with the contact surface is increased, and higher airtightness can be obtained. Furthermore, since the above-mentioned connecting portion has an extremely simple structure, it is easy to construct and disassemble, and thus the cable 1 can be easily reconnected.

As explained above, in the connection part of the communication cable of this invention, the gas pressure inside the connection case expands the end plate from inside the groove in the inner and outer circumferential directions, causing the sealing material to come into close contact with the connection case, thereby making the inside of the connection case airtight. Since it is sealed for a long time, high airtightness can be maintained for a long period of time. Furthermore, since the pillars are provided between the grooves, there is no fear that the grooves will become clogged. Furthermore, since the structure is extremely simple, it is easy to disassemble, and therefore cables can be easily reconnected.
