DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0023] like Figure 1As shown, a missile matching cable comprises a cable core 1, an inner flame retardant cushion layer 2, a general shielding layer 3, an outer flame retardant cushion layer 4, and an outer sheath 5. The inner flame retardant cushion layer, the general shielding layer, the outer flame retardant cushion layer, and the outer sheath are sequentially coated on the cable core from the inside to the outside.

[0024] The cable core has a three-layer structure, including an inner layer, a wrapping layer 10, and an outer layer from the inside to the outside. The inner layer includes a first signal line 11, a second signal line 12, a data bus 31, and a core filling 32. The wrapping layer is wound on the inner layer to fix the inner layer as a whole. The wrapping layer is an aluminum-plastic composite tape, which improves the overall mechanical strength and has a certain shielding ability. The outer layer includes a third signal line 13, a fourth signal line 14, a fifth signal line 15, a first power line 21, a second power line 22, and a third power line 23 arranged around the wrapping layer. Since the cable core includes power lines, signal lines, and data buses, it is highly integrated, the construction is more convenient, the wiring is more beautiful, and the space utilization rate of the ship laying site can be fully optimized.

[0025] The data bus is a 1553B data bus, and the number is two. The number of the core filling is one. The first signal line, the third signal line, the fourth signal line, and the fifth signal line are all twisted pairs with shielding layers. The second signal line is a single line with a shielding layer. The first power line, the second power line, and the third power line are all twisted pairs. The data bus, the first signal line, the second signal line, the third signal line, the fourth signal line, and the fifth signal line are used to transmit signals. The first power line, the second power line, and the third power line are used to provide power supply guarantee for the cabinet.

[0026] As a preference: the first signal line is two 0.35mm 2 The first signal line is one; the second signal line is 0.35mm 2 The number of the second signal wires is thirty-one; the third signal wires are two 2.5mm 2 The number of the third signal wires is two; the fourth signal wire is two 2.0mm 2 The fourth signal line is two; the fifth signal line is two 1.2mm 2 The first power line is two 1.5mm 2 The first power line is one; the second power line is two 1.2mm 2 The second power line is one; the third power line is two 3.0mm 2 The third power supply wires are composed of twisted insulated core wires, and the number of the third power supply wires is two.

[0027] Preferably, the first signal line, the second signal line, the third signal line, the fourth signal line, and the fifth signal line are all three-layer structures, including an insulating core wire layer 41 (one insulating core wire or two twisted insulating core wires), a shielding layer 42, and a sheath 43. Since each signal line has a shielding layer, the electromagnetic compatibility of each shielding unit can be guaranteed. The insulating core wire includes a conductor and an insulating layer. The conductor is a silver-plated twisted conductor, which is twisted with a small pitch to resist external electromagnetic interference, more effectively guarantee the quality of signal transmission, and realize the integrated transmission of multiple lines in a smaller space, while also ensuring good flexibility.

[0028] The insulating layer is made of FEP material (fluorinated ethylene propylene), which not only ensures the insulating electrical and mechanical properties, but also ensures the high and low temperature resistance.

[0029] The inner flame retardant cushion layer and the outer flame retardant cushion layer are made of low-smoke halogen-free flame retardant fabric tape. The low-smoke halogen-free flame retardant fabric tape is made of halogen-free material and does not contain toxic chemicals such as chlorine and bromine. When a fire occurs, it can prevent the flame from burning the wires and will not produce harmful gases, thereby effectively reducing casualties and property losses.

[0030] The total shielding layer is a tinned braided shielding layer with a density greater than or equal to 90%, which makes the cable have stronger anti-interference ability; the total shielding layer is wrapped inside and outside by the inner flame retardant cushion layer and the outer flame retardant cushion layer. This design can avoid direct contact between the tinned structure of the total shielding layer and other cable structures to extend the service life. In addition, the wrapping layer of the aluminum-plastic composite tape and the tinned braided shielding layer form a combined shielding, which ensures the electromagnetic compatibility of each shielding unit and improves the stability of signal transmission.

[0031] In order to enable the missile supporting cables to cope with the relatively harsh working environment at sea, the outer sheath is made of TPV material (cold-resistant low-smoke halogen-free flame-retardant elastomer). The outer sheath has the characteristics of high and low temperature resistance (temperature resistance -55 to 125 degrees), flame retardant (reaching V0 level), low smoke and halogen-free, mildew resistance (not greater than level 0), salt spray resistance, sunlight radiation resistance (meeting the GJB150.7 sunlight radiation test), and oil resistance (meeting the oil resistance test specified in GJB1916), which can play a better protective role in harsh working environments.

[0032] All components of the utility model are prior art and can be purchased from outside.

[0033] The preferred embodiments of the present invention are shown in the accompanying drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described in this specification. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.
