Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a multi-core coaxial cable. Background Art

[0002] Coaxial cable is a kind of wire and signal transmission line, which is mainly used for the transmission of analog and digital signals. Multi-core coaxial cable integrates multiple coaxial cables into one cable to facilitate the laying of lines. When using traditional multi-core coaxial cables, multiple coaxial cables are often directly wrapped with rubber sleeves. At this time, multiple coaxial cables are directly attached together, and the buffering effect is poor, which may cause damage to the multi-core coaxial cable. For this reason, we propose a multi-core coaxial cable to facilitate the protection of the cable. Utility Model Content

The filling layer A is filled between the inner wall of the insulating sleeve and the rubber sleeve, and the filling layer B is filled at the inner wall of the rubber sleeve.

[0005] By adopting the above technical scheme, when protecting the multi-core coaxial cable, since a protective mechanism is installed on the inner wall of the insulating sleeve, the protective mechanism is composed of a filling layer A, a rubber sleeve and a filling layer B. The insulating sleeve and the rubber sleeve are filled with the filling layer A, the inner wall of the rubber sleeve is filled with the filling layer B, and the main body of the cable conductor is located in the filling layer B. Since the materials of the filling layer A and the filling layer B are both aluminum foil materials, the aluminum foil material has good buffering and pressure resistance, thereby realizing protection of the multi-core coaxial cable.

[0006] Specifically, it also includes a blocking mechanism, and the inner wall of the filling layer B is connected to the blocking mechanism.

[0007] By adopting the above technical solution, the cable conductor body can be protected by the blocking mechanism.

[0008] Specifically, the blocking mechanism is composed of a protective sleeve, a metal mesh sleeve, a metal wrapping layer, a resin layer and a cable conductor body. Two groups of symmetrical protective sleeves are sleeved on the inner wall of the filling layer B, the two groups of protective sleeves are sleeved on the inner wall of the sleeves with metal mesh sleeves, the metal wrapping layer is sleeved on the inner wall of the metal mesh sleeve, the resin layer is sleeved on the inner wall of the metal wrapping layer, and the cable conductor body is plugged on the inner wall of the resin layer.

[0009] By adopting the above technical scheme, when increasing the protection for the main body of the cable conductor, since the inner wall of the filling layer B is connected with a blocking mechanism, the blocking mechanism is composed of a protective sleeve, a metal mesh sleeve, a metal wrapping layer, a resin layer and a main body of the cable conductor, after the protective sleeve is wrapped by the filling layer B, the material of the protective sleeve is an insulating rubber material, the inner wall of the protective sleeve is connected with a metal mesh sleeve, the inner wall of the metal mesh tube is connected with a metal wrapping layer, the main body of the cable conductor is shielded by the metal mesh sleeve and the metal wrapping layer, the main body of the cable conductor is located in the resin layer, and the resin layer is located in the metal wrapping layer, thereby achieving barrier protection for the main body of the cable conductor.

[0010] Specifically, reinforcing ribs are inserted and connected in the filling layer B, and the reinforcing ribs are located between the protective sleeves.

[0011] By adopting the above technical solution, the tensile strength of the cable is increased by reinforcing ribs.

[0012] Specifically, the filling layer A and the filling layer B are both made of aluminum foil.

[0013] By adopting the above technical solution, the cable is protected by extruding and overlapping the aluminum foil materials.

[0014] Beneficial effects of the utility model:

Since the filling layer A and the filling layer B are both made of aluminum foil, the aluminum foil has good buffering and pressure resistance, thereby protecting the multi-core coaxial cable.

[0016] (2) The multi-core coaxial cable described in the present invention provides additional protection for the main body of the cable conductor. Since a barrier mechanism is connected to the inner wall of the filling layer B, the barrier mechanism is composed of a protective sleeve, a metal mesh sleeve, a metal sheath, a resin layer and a main body of the cable conductor. After the protective sleeve is wrapped by the filling layer B, the material of the protective sleeve is an insulating rubber material. The inner wall of the protective sleeve is connected to a metal mesh sleeve, and the inner wall of the metal mesh tube is connected to a metal sheath. The main body of the cable conductor is shielded by the metal mesh sleeve and the metal sheath. The main body of the cable conductor is located in the resin layer, and the resin layer is located in the metal sheath, thereby achieving barrier protection for the main body of the cable conductor.
