[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] Example
[0024] See also Figure 1-Figure 3 As shown, this embodiment provides an electromagnetic interference-enhanced military power supply, including an installation component 10, the installation component 10 includes a main shell 11, a mounting groove 12 is opened on one side of the main shell 11, a power supply body 20 is arranged in the mounting groove 12, an auxiliary shell 13 is arranged on the side of the main shell 11 away from the power supply body 20, and a protective pad 30 is arranged between the inner wall of the power supply body 20 and the auxiliary shell 13. The installation component 10 is used to protect the power supply body 20 from electromagnetic interference, and then the power supply body 20 is mechanically protected by the protective pad 30.
[0025] Working principle: When the electromagnetic interference-resistant enhanced military power supply provided by the utility model is used, the installation component 10 is provided to protect the power supply body 20 from electromagnetic interference, and the protective pad 30 is used to mechanically protect the power supply body 20; in addition, when the power supply body 20 is not in use, the auxiliary shell 13 is pushed to fit with the main shell 11, and the protective pad 30 made of rubber material is used to mechanically protect the power supply body 20. When in use, the auxiliary shell 13 is pulled away from the main shell 11, thereby facilitating the use of the power supply body 20.
[0026] In order to mechanically protect the power supply body 20, the main shell 11 is slidably connected to the auxiliary shell 13. An operation port 14 is provided on the side of the auxiliary shell 13 away from the main shell 11, and a shielding door 15 is hinged in the operation port 14. The main shell 11 and the auxiliary shell 13 are both made of copper. When not in use, the auxiliary shell 13 is pushed to fit the main shell 11, and the power supply body 20 is mechanically protected with a protective pad 30 made of rubber. When in use, the auxiliary shell 13 is pulled away from the main shell 11, thereby facilitating the use of the power supply body 20.
[0027] Considering the need to provide electromagnetic protection for the power source body 20, a plurality of grids are provided on the shielding door 15. The principle is that the metal grid is conductive, and when electromagnetic waves hit the surface of the metal grid, part of the electromagnetic waves will be reflected by the metal grid, while the other part will be absorbed by the metal grid, thereby effectively weakening or preventing the propagation of the electromagnetic waves.
[0028] In order to achieve further electromagnetic protection for the power source body 20, a conductive coating is applied to the inner wall of the placement slot 12. The principle is that the conductive coating has good electromagnetic wave reflection and absorption capabilities. When external electromagnetic waves or interference signals are projected onto the surface of the conductive coating, part of the electromagnetic waves will be reflected by the coating surface, while the other part will be absorbed by the coating. In this way, the conductive coating can effectively weaken or prevent the propagation of electromagnetic waves. In addition, the conductive coating forms a conductive shielding layer that can effectively block the penetration of external electromagnetic waves or interference signals. Since the conductive coating has good conductivity, the propagation of electromagnetic waves on the coating surface will be hindered, thereby reducing interference with the protected object.
[0029] In order to provide electromagnetic and mechanical protection to the power source body 20 at the same time, the material of the protective pad 30 is conductive rubber. The principle is as follows: the conductive property of the conductive rubber enables it to absorb and reflect electromagnetic waves. When external electromagnetic waves or interference signals are projected onto the surface of the conductive rubber, part of the electromagnetic waves will be absorbed by the rubber surface, while the other part will be reflected by the conductive network inside the rubber. In this way, the conductive rubber can effectively weaken or prevent the propagation of electromagnetic waves. In addition, the conductive rubber is soft and plastic, and can adapt to various shapes and surfaces, so it is suitable for various forms of electromagnetic shielding applications.
[0030] The anti-electromagnetic interference enhanced military power supply provided in the utility model is used to protect the power supply body 20 from electromagnetic interference through the installation component 10 when it is used. Specifically, the main shell 11 and the auxiliary shell 13 are made of copper. When not in use, the auxiliary shell 13 is pushed to fit with the main shell 11, and the protective pad 30 made of rubber material is used to mechanically protect the power supply body 20. When in use, the auxiliary shell 13 is pulled away from the main shell 11, so as to facilitate the use of the power supply body 20; the power supply body 20 is then mechanically protected by the protective pad 30. Specifically, the conductive property of the conductive rubber enables it to absorb and reflect electromagnetic waves. When external electromagnetic waves or interference signals are projected onto the surface of the conductive rubber, part of the electromagnetic waves will be absorbed by the rubber surface, while the other part will be reflected by the conductive network inside the rubber. In this way, the conductive rubber can effectively weaken or prevent the propagation of electromagnetic waves; in addition, the conductive rubber has softness and plasticity, and can adapt to various shapes and surfaces, so it is suitable for various forms of electromagnetic shielding applications.

Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
