In communication cables that require gas maintenance, pressurized air or nitrogen gas is sealed inside the cables, so it is necessary to prevent gas leakage from the connections. Conventionally, methods for configuring the above-mentioned cable connections include the auxiliary lead pipe method that uses heat, the GS cable method, the heating wire fusion method, the see-through fusion method, and the airtight method, or purely mechanically, using sealing tape. Airtight construction methods are used.

があつた。 However, these conventional airtight cable connection methods are cumbersome and require the use of heat, or involve wrapping multiple layers of highly adhesive sealing tape, resulting in poor workability. 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 methods that use non-adhesive rubber packing to compensate for these drawbacks of conventional methods, but in both cases, the flow of the sealing material and the expansion of the auxiliary lead pipe can cause sealing failures, resulting in the joints becoming damaged over a long period of time. There were disadvantages such as a lack of reliability, such as poor airtightness and gas leaks.

A recessed portion having a U-shaped cross section and fan-shaped is formed along the recess, and the recessed portion forms a thin walled portion 23 on the inner and outer peripheries of the half-split body 6. A thick wall portion 24 is provided on the end surface.
is formed. Further, by these recesses, spaces (gas inflow portions) 14, 14 are formed inside the half bodies 6, 6, respectively, to communicate with the inside of the connection case 17. Moreover, the half bodies 6, 6 of the end face member 5
There are multiple pieces (four pieces in the figure) along the circumferential direction on the outer circumferential surface.
An annular protrusion 15 is formed. Here, a sealing material 16 similar to the sealing material 10 is also wound around the outer periphery of the end face member 5 on which the protrusions 15 are formed. A connection case 17 is provided on the outer periphery of the end face member 5 with the sealing material 16 interposed therebetween. The connection box 17 has a substantially cylindrical appearance, and the halves 18, 18 are divided into two equal parts along the axial direction, and the bolts 19,... and the nuts 20,...
It is integrally connected by. At the end of the connection box 17 and at a position slightly longer than the width of the end face member 5 from the end in the longitudinal direction, there are annular shapes projecting radially inward, respectively. Locking protrusions 21, 21 are formed. The connection case 17 is attached to the outer periphery of the end member 5 so that the outer periphery of the end member 5 is sandwiched between the locking protrusions 21, 21. Further, the other end (not shown) of the connection case 17 is similarly attached to the outer periphery of an end face member provided on the other cable jacket.

接続用函体１７内は気密に保持される。 In the connection part of the communication cable constructed in this way, when gas for gas maintenance is pressurized and sealed into the cable 1, the outer sheath 4 is peeled off and the above-mentioned space 22 is also connected to the above-mentioned space 22 through the exposed conductor connection part 3. Since it is filled with gas, the inside of the connection case 17 is pressurized to the same pressure as the inside of the cable 1. Then, the connection case 1
The gas in 7 flows into the cavity 14 of the end member 5 as shown by the arrow in FIG. 1, and the cavity 14 expands. As a result, the thin portion 23 of the end face member 5 expands outward. Therefore, the protrusions 8..., 15... formed on the middle and outer peripheral surfaces of the end face member 5 are tightly adhered to the outer jacket 4 of the cable 1 and the inner peripheral surface of the connection case 17 via the sealing materials 10, 16, respectively. Therefore, the inside of the connection case 17 is kept airtight.

る。 According to such communication cable connection portion and connection method, the thin wall portion 23 of the end face member 5 expands due to the gas pressure inside the connection case 17, thereby airtightly sealing the inside of the connection case 17. Therefore, high airtightness can be maintained. Furthermore, the structure is extremely simple and it is easy to remove, so that the cable 1 can be easily reconnected. Furthermore, annular protrusions 8..., 15... are formed on the inner and outer peripheral surfaces of the end face member 5.
Since this is provided, the sealing effect between the contact surface and the contact surface is increased, and therefore higher airtightness can be obtained.

を示すものである。 In this experiment, an aluminum pipe with a pressure sensor built into its surface was used instead of a cable, and the cable connection part and the cable connection part according to the present invention were simulated on the outer circumference of the aluminum pipe using the conventional auxiliary lead pipe construction method. The degree of adhesion to the outer periphery of the aluminum pipe at each of the connecting portions formed was measured as a pressure value using the pressure sensor. In FIG. 3, the horizontal axis represents the passage of time, and the vertical axis represents the measured value of the pressure sensor that changes with the passage of time.

ないことがわかる。 As is clear from the graph shown in Fig. 3, in the case of the conventional connection shown by A in the figure, the adhesion pressure to the outer circumference of the pipe gradually decreases over time due to the fitting of the lead pipe, etc. Maintaining airtightness within the joint must rely solely on the adhesive strength of the sealing tape. On the other hand, in the case of the present invention, even if the bolt tightening force decreases due to the fitting of the bolt tightening part, the maintenance gas pressure in the connection part will cause the end face member to move toward its inner and outer circumferences. It can be seen that since the end face member is inflated and pressed against the pipe, the end face member always comes into close contact with the outer circumferential portion of the pipe at a pressure P substantially corresponding to the maintenance gas pressure, so that the airtightness does not deteriorate over time.

As explained above, in the communication cable connection method and connection part of the present invention, the gas supplied into the connection case flows into the gas inflow part of the end face member, and this gas inflow part expands. As a result, the thin inner and outer circumferential parts of the end face member are expanded in the radial direction and are brought into close contact with the connection case and the outer sheath of the cable, and the inside of the connection case is airtightly sealed, so that airtightness is not reduced. High airtightness can be maintained, the structure is extremely simple, and since it is easy to remove as well as remove, cables can be easily reconnected. Furthermore, if an annular protrusion along the circumferential direction is provided on the inner circumferential surface or outer circumferential surface of the end face member, the sealing effect can be further increased.
