Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a cable for a sonobuoy that connects a buoy floating on the sea surface and equipment such as a sonar, which is a listening device installed in the sea, and in particular, to a sonar terminal. The present invention relates to a sonobuoy cable that is provided with a branch connection section that enables connection.

[Prior Art] A sonobuoy cable, which is made by twisting together enameled wires, tension members, steel wires, or stainless steel wires and applying an insulating coating thereon, is a thin cable with excellent tensile strength.

[Problems to be Solved by the Invention] However, when attaching such a sonobuoy cable to a sonar terminal, in order to attach the enameled wire to the terminal as it is, a special method is required because the enameled wire is thin and its enamel layer is thin. In addition to requiring special techniques, the insulator coating is extremely thin, so cutting the insulator to expose the internal enamelled wire and tension member, and separating the two may result in scratches, resulting in loss of insulation resistance, or damage during use. Since the separated part becomes a rigid inflection point, there are disadvantages such as repeated bending and wire breakage, and although it is an excellent sonobuoy cable, its use is limited.

SUMMARY OF THE INVENTION An object of the present invention is to solve the problems of the prior art described above and to provide a new sonobuoy cable that can be connected to a sonar terminal in the same way as a normal insulated wire.

[Means for Solving the Problems] The sonobuoy cable according to the present invention has a branch connection section provided at a predetermined location of the sonobuoy cable by connecting the core conductor of the insulated wire to each core conductor of the enamelled wire. It is something.

As the insulated wire, a general insulated wire coated with a well-known material such as rubber, polyethylene, or polyvinyl chloride is used.

[Embodiment] Fig. 1 is a sectional view showing an embodiment of the sonobuoy cable according to the present invention. The wire 2 and the tension member 3 are twisted together, and the insulator coating 1 is placed on top of the twisted wire 2 and the tension member 3.
1 has been applied. In the branch connection section 10 provided on the sonobuoy cable 1, the enamelled wire 2 and the tension member 3 are separated by covering the tension member 3 with a protective cap 4 at the point where the insulator coating 11 is removed. Next, the core conductor 2A of each enameled wire 2 and the core conductor 5A of the general insulated wire 5 are individually connected at the connection point 6. After connection, the enamelled wire 2 and its core conductor 2A and the insulated wire 5 and its core conductor 5A are covered with an insulator 7, a protective layer 8 is applied thereon, and a sleeve 9 is further coated.

Such branch connections 10 may be provided at both ends of the sonobuoy cable 1 as shown in FIG. 2, or at both ends and at an intermediate point as shown in FIG.

[Effect of the invention] As described above, the sonobuoy cable of the present invention has the following effects:
Since the branch connection portion is provided by separately connecting the core conductor of the enamelled wire and the core conductor of the insulated wire, there is an effect that connection to the sonar terminal becomes extremely easy.
