[0021] The following is a further detailed description of the specific embodiments of the present utility model, such as the shapes, structures of the various components involved, the mutual positions and connection relationships between the various parts, the functions and working principles of the various parts, etc., with reference to the drawings:

[0022] As shown in the attached Figure 1As shown in the figure, the utility model relates to an electromagnetic interference resistant structure for a ship electronic system. The equipment connection cable body 2 includes a single cable or multiple cables. The outer circle of the equipment connection cable body 2 is wrapped with a tin foil layer 3. A metal fastening clip 4 is arranged outside the tin foil layer 3. One end of the grounding conductor 5 is connected to the metal fastening clip 4, and the other end of the grounding conductor 5 is connected to the grounding end 6. The grounding end 6 is welded to the ship bulkhead or ship deck near the grounding part. For the deficiencies in the prior art, the above structure proposes an improved technical solution. When setting up the structure, the equipment is connected through the equipment connection cable body 2. To reduce and eliminate electromagnetic interference between ship equipment and systems and external electromagnetic interference, the structure of the equipment connection cable body 2 is improved to set up an electromagnetic interference resistant structure for the ship electronic system. As different embodiments of the structure, the equipment connection cable body 2 can be a single cable or multiple cables. The outer circle of the equipment connection cable body 2 is wrapped with a tin foil layer 3. A metal fastening clip 4 is arranged outside the tin foil layer 3. The tin foil layer 3 is used for conducting electricity. One end of the grounding conductor 5 is connected to the metal fastening clip 4, and the other end of the grounding conductor 5 is connected to the grounding end 6. In this way, the grounding conductor 5 is connected to the metal fastening clip 4, that is, the grounding conductor 5 is connected to the equipment connection cable body 2. The grounding end 6 is welded to the ship bulkhead or ship deck near the grounding part, and the grounding of the equipment connection cable body 2 is reliably realized. In this way, through the change of the reliable grounding structure, the engineering state that all electronic systems on the ship are compatible with each other and do not interfere with each other is satisfied, electromagnetic interference between ship equipment and systems and external electromagnetic interference are reduced and eliminated, electromagnetic hazards are reduced, the safety of personnel and weapon systems is guaranteed, the anti-interference ability between various equipment is improved, the electromagnetic compatibility of equipment and systems is realized, the energy efficiency of ship equipment and systems is maximally exerted, and the ship exerts the maximum combat effectiveness. The electromagnetic interference resistant structure for the ship electronic system described in the utility model has a simple structure, can effectively enhance the electromagnetic interference resistance ability of the cable, solve the problem of electromagnetic compatibility of equipment, and improve the reliability of the electronic system.

[0023] When the equipment connection cable body 2 described includes multiple cables, an insulating sheath 7 is wrapped around the outer circles of the multiple cables. A sheath stripping area 8 is arranged at the position where the insulating sheath 7 wraps the tin foil layer 3. When the equipment connection cable body 2 described includes multiple cables, a convex part 9 arranged along the inner circle for one week is arranged inside the inner circle of the metal fastening clip 4. The convex part 9 is located in the sheath stripping area 8. For the above structure, as a specific embodiment, as shown in the appendix Figure 2As shown, a single cable cannot meet the requirements for the equipment connection cable body 2 of some equipment, so multiple cables are set. The outer circles of the multiple cables are wrapped with an insulating sheath 7. In this way, it is necessary to strip the insulating sheath 7 at the part of the equipment connection cable body 2 where the tin foil layer 3 is to be set, then wrap the tin foil layer in the sheath stripping area 8, and then set the metal fastening clip 4. Since the sheath stripping area 8 is a concave structure, after the metal fastening clip is set, the metal fastening clip 4 is in a suspended state at the sheath stripping area 8 and cannot reliably contact the tin foil layer 3, and naturally cannot reliably fit with the equipment connection cable body 2. Therefore, a convex portion 9 arranged along the inner circle for one week is set on the inner circle of the metal fastening clip 4. When the metal fastening clip 4 is sleeved on the outer circle of the equipment connection cable body 2, the convex portion 9 is clamped in the sheath stripping area 8, which not only realizes the limiting effect on the metal fastening clip 4 to prevent the metal fastening clip 4 from moving relative to the equipment connection cable body 2, but also enables the metal fastening clip 4 to reliably contact the tin foil layer through the convex portion 9, realizing the contact connection of the components.

[0024] The equipment connection cable body 2 is provided with ship electronic system anti-electromagnetic interference structures respectively near both ends. The equipment connection cable body 2 is provided with multiple ship electronic system anti-electromagnetic interference structures at intervals. For the above structures, multiple grounding points can be set according to the needs of different equipment, so as to effectively reduce the influence of electromagnetic interference and reliably solve the problem of electromagnetic compatibility.

[0025] The metal fastening clip 4 is a metal clamp or a metal tie. For the above structure, the metal fastening clip 4 is a metal clamp or a metal tie. On the one hand, it is used to connect the grounding conductor 5. On the other hand, when the equipment connection cable body 2 is multiple cables, it is used to restrain the multiple cables.

[0026] The metal fastening clip 4 and the convex portion 9 are of an integral structure. The convex portion 9 of the metal fastening clip 4 for connecting the grounding conductor 5 is provided with a groove, and the grounding conductor 5 is connected to the metal fastening clip 4 through the collar portion 1, and the collar portion 1 is clamped in the groove of the convex portion 9. For the above structure, the grounding conductor 5 is connected to the metal fastening clip 4 through the collar portion 1, and the collar portion 1 is clamped in the groove of the convex portion 9, improving the connection reliability between the grounding conductor 5 and the metal fastening clip 4 and enhancing the grounding effect.

[0027] Two to three layers of the tin foil layer 3 are set. For the above structure, the setting of multiple layers of the tin foil layer effectively guarantees the wrapping effect on the equipment connection cable body 2 and helps to improve the grounding reliability.

[0028] The anti-electromagnetic interference structure of the ship electronic system described in the present utility model is configured such that the devices are connected through the device connection cable body 2. To reduce and eliminate electromagnetic interference between shipboard devices and systems and external electromagnetic interference, the structure of the device connection cable body 2 is improved to provide the anti-electromagnetic interference structure of the ship electronic system. As different embodiments, the device connection cable body 2 can be a single cable or multiple cables. A tin foil layer 3 is wrapped around the outer circumference of the device connection cable body 2, and a metal fastening clip 4 is provided outside the tin foil layer 3. The tin foil layer 3 is used for conducting electricity. One end of the grounding conductor 5 is connected to the metal fastening clip 4, and the other end of the grounding conductor 5 is connected to the grounding end 6. In this way, the grounding conductor 5 is connected to the metal fastening clip 4, that is, the grounding conductor 5 is connected to the device connection cable body 2. The grounding end 6 is welded to the ship's bulkhead or ship's deck near the grounding location, reliably achieving the grounding of the device connection cable body 2. In this way, through reliable grounding treatment, the engineering state where all ship electronic systems are mutually compatible and do not interfere with each other is satisfied, reducing and eliminating electromagnetic interference between shipboard devices and systems and external electromagnetic interference, reducing electromagnetic hazards, ensuring the safety of personnel and weapon systems, improving the anti-interference ability between devices, achieving electromagnetic compatibility of devices and systems, maximizing the energy efficiency of shipboard devices and systems, and enabling the ship to exert its maximum combat effectiveness.
