Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a crossover cable for locomotive vehicles. Background Art

[0002] A cable is a power or signal transmission device composed of several or several groups of wires. The crossover cable for locomotive vehicles is applied in locomotives, passenger cars, and high-speed rails for connecting each carriage. Developing the crossover cable for railway locomotive vehicles can not only contribute to the localization of railway locomotive equipment in China, but also greatly promote the progress and development of China's wire and cable industry in aspects such as design technology, material technology, manufacturing technology, and test technology.

[0003] The crossover cable for locomotive vehicles needs to be able to connect the train power supply circuit, control signal, and network signal. However, after long-term use, the existing cable will have a decrease in strength due to aging. Therefore, the cable needs higher strength to cope with the complexity of vehicle operation. To improve the performance of the crossover cable for locomotive vehicles, the utility model proposes a crossover cable for locomotive vehicles. Summary of the Utility Model

[0004] To solve the technical problems in the background art, the utility model proposes a crossover cable for locomotive vehicles.

[0005] The crossover cable for locomotive vehicles proposed by the utility model includes a plurality of conductors and an outer sheath. A shielding layer is arranged inside the outer sheath, and a braided layer is arranged inside the shielding layer.

[0006] Preferably, the outer sheath is a rubber composite sheath.

[0007] Preferably, the shielding layer is made of a semi-conductive material.

[0008] Preferably, a filling layer is arranged between the plurality of conductors and the braided layer.

[0009] Preferably, the filling layer includes a plurality of glass fiber filament layers and a plurality of polyester tape layers, and the plurality of glass fiber filament layers and the plurality of polyester tape layers are arranged at intervals.

[0010] Preferably, the braided layer is formed by braiding aramid fibers.

[0011] In the utility model, the proposed crossover cable for locomotive vehicles has the following beneficial technical effects:

[0012] Through the arrangement of the braided layer, due to the soft texture, low density, high strength and high modulus of aramid fibers, the mechanical properties of the cable are further enhanced. The multiple glass fiber filament layers and multiple polyester tape layers of the filling layer are arranged at intervals. Glass fibers have higher heat resistance, non-combustibility, corrosion resistance, heat insulation and sound insulation than polyester tapes, high tensile strength and good electrical insulation, while polyester tapes are light in weight, flexible, and have high strength and elasticity. Therefore, they are durable and wrinkle-resistant, and due to the arrangement of multiple glass fiber filament layers and multiple polyester tape layers at intervals, they combine the advantages of glass fiber filaments and polyester tapes, further enhancing the performance of the locomotive and rolling stock jumper cable.

[0013] Additional aspects and advantages of the present utility model will be given in part in the following description, become apparent in part from the following description, or be learned through the practice of the present utility model. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the drawings, where the same or similar symbols represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0018] As Figure 1 - Figure 2 shown, a locomotive and rolling stock jumper cable includes a plurality of conductors 1, and further includes an outer sheath 2. A shielding layer 3 is fixedly connected inside the outer sheath 2, and a braided layer 4 is fixedly connected inside the shielding layer 3.

[0019] A further improvement of the technical solution lies in that the outer sheath 2 is a rubber composite sheath.

[0020] A further improvement of the technical solution lies in that the shielding layer 3 is made of a semi-conductive material, and the shielding layer 3 is composed of a semi-conductive material with a very low resistivity and a relatively thin thickness.

[0021] A further improvement of the technical solution lies in that a filling layer 5 is fixedly connected between the plurality of conductors 1 and the braided layer 4. The filling layer 5 includes a plurality of glass fiber filament layers 51 and a plurality of polyester tape layers 52, and the plurality of glass fiber filament layers 51 and the plurality of polyester tape layers 52 are arranged at intervals.

[0022] A further improvement of the technical solution lies in that the braided layer 4 is formed by braiding aramid fibers, and due to the soft texture, low density, high strength and high modulus of aramid fibers, the mechanical properties of the cable are further enhanced.

[0023] Through the arrangement of the braided layer 4, due to the soft texture, low density, high strength and high modulus of aramid fibers, the mechanical properties of the cable are further enhanced. The multiple glass fiber layers 51 and multiple polyester tape layers 52 of the filling layer 5 are arranged at intervals. Glass fibers have higher temperature resistance, are non-combustible, corrosion-resistant, heat-insulating, sound-insulating, have high tensile strength and good electrical insulation, while polyester tapes are light in weight, flexible, have high strength and elasticity. Therefore, they are durable and wrinkle-resistant, further enhancing the performance of the locomotive vehicle jumper cable.
