Description

Technical Field

[0001] This utility model relates to the field of electromagnetic shielding cylinder cover technology, and in particular to an integrated threaded shielding cylinder cover. Background Technology

[0002] Many shielding cylinder covers on the market use a single-layer shielding structure. This structure has poor electromagnetic shielding effect when facing complex electromagnetic environments. Because it relies on only a single shielding layer, it is difficult to effectively block electromagnetic wave interference of different frequencies. For example, in some aerospace equipment scenarios with high requirements for electromagnetic shielding, the shielding cylinder cover with a single-layer shielding structure cannot provide sufficient protection for internal components, which affects the normal operation of the equipment.

[0003] Furthermore, single-layer shielding structures also pose serious hidden dangers in the sealing process. When performing sealing operations, staff cannot intuitively and accurately know the actual sealing effect. In practical applications, once the sealing fails, external electromagnetic waves can easily enter through gaps and other parts, causing the electromagnetic shielding effect of the entire device to fail, greatly reducing the insulation performance of the equipment, and affecting the normal use and safety performance of the equipment. Utility Model Content

[0004] In order to overcome the problem that the electromagnetic shielding effect of the existing shielding cylinder cover is poor due to its single-layer shielding structure, and that the staff cannot know the sealing effect of the single-layer shielding structure during sealing, resulting in the failure of the overall electromagnetic shielding effect of the device, this utility model provides an integrated threaded shielding cylinder cover.

[0005] The technical solution is as follows: An integrated threaded shielding cylinder cover includes an electromagnetic shielding component and an electromagnetic monitoring component; the electromagnetic monitoring component is disposed inside the circular part of the electromagnetic shielding component; the electromagnetic shielding component includes a first electromagnetic shielding cover, a second electromagnetic shielding cover, a third electromagnetic shielding cover, a fourth electromagnetic shielding cover, a handle, and an insulating rubber column; the electromagnetic monitoring component includes an electromagnetic shielding rod, an electromagnetic monitoring sensor, a locking nut, an electromagnetic shielding washer, an electromagnetic shielding cable, and an electromagnetic signal alarm light; the second electromagnetic shielding cover, the third electromagnetic shielding cover, and the fourth electromagnetic shielding cover are disposed inside the first electromagnetic shielding cover, and the first electromagnetic shielding cover, the second electromagnetic shielding cover, the third electromagnetic shielding cover, and the fourth electromagnetic shielding cover are arranged sequentially from the outside to the inside.

[0006] Furthermore, insulating rubber pillars are provided between the first electromagnetic shielding cover, the second electromagnetic shielding cover, the third electromagnetic shielding cover, and the fourth electromagnetic shielding cover, and the insulating rubber pillars are fixedly connected to the first electromagnetic shielding cover, the second electromagnetic shielding cover, the third electromagnetic shielding cover, and the fourth electromagnetic shielding cover.

[0007] Furthermore, an electromagnetic shielding rod is provided inside the center of the electromagnetic shielding component, and an electromagnetic monitoring sensor is provided at the lower end of the electromagnetic shielding rod. The electromagnetic monitoring sensor is integrally formed with the electromagnetic shielding rod, and the model of the electromagnetic monitoring sensor is Mag639.

[0008] Furthermore, the electromagnetic shielding rod is equipped with locking nuts on the outside, and the upper and lower locking nuts are a group. There are two groups of locking nuts, and an electromagnetic shielding gasket is provided on the inner side of one group of locking nuts.

[0009] Furthermore, the upper and lower sets of locking nuts are respectively set on the outside of the central holes of the third and fourth electromagnetic shielding covers for clamping.

[0010] Furthermore, an electromagnetic shielding cable is installed at the upper end of the electromagnetic shielding rod, and the cable inside the electromagnetic shielding cable is electrically connected to the electromagnetic monitoring sensor; an electromagnetic signal alarm light is installed on one side of the electromagnetic shielding cable, and the electromagnetic signal alarm light is electrically connected to the signal light control unit inside the electromagnetic shielding rod.

[0011] Furthermore, a handle is provided at the upper end of the first electromagnetic shielding cover, and the handle is fixedly connected to the first electromagnetic shielding cover.

[0012] The beneficial effects are as follows: To achieve efficient electromagnetic protection, this utility model employs a multi-layered protection design for the electromagnetic shielding component. The first, second, third, and fourth electromagnetic shielding covers are nested together sequentially to form a multi-layered shielding structure. The handle facilitates handling and operation of the component, while the insulating rubber pillars provide support and insulation for the fourth electromagnetic shielding cover, ensuring the relative stability of the shielding covers. Through this combined design, the multi-layered electromagnetic shielding covers effectively block external electromagnetic interference, providing reliable electromagnetic protection for the internal space of the fourth electromagnetic shielding cover.

[0013] By setting up the electromagnetic monitoring component, the locking nut of the electromagnetic monitoring component threads the electromagnetic shielding rod into the hole at the center of the electromagnetic shielding component. Then, the hole of the electromagnetic shielding component is shielded by an electromagnetic shielding gasket, thereby improving the electromagnetic shielding effect. The electromagnetic shielding cable is used to supply power and transmit signals to the electromagnetic monitoring sensor under electromagnetic protection. When the electromagnetic monitoring sensor detects an abnormal electromagnetic signal that interferes inside the fourth electromagnetic shielding cover, it will emit an alarm signal light through the electromagnetic signal alarm light to remind the staff that the electromagnetic shielding component has not been sealed as required, preventing the electromagnetic shielding component from failing due to improper installation.

[0026] An electromagnetic shielding cable 205 is provided at the upper end of the electromagnetic shielding rod 201, and the cable inside the electromagnetic shielding cable 205 is electrically connected to the electromagnetic monitoring sensor 202; an electromagnetic signal alarm light 206 is provided on one side of the electromagnetic shielding cable 205, and the electromagnetic signal alarm light 206 is electrically connected to the signal light control unit inside the electromagnetic shielding rod 201.

[0027] The electromagnetic shielding assembly 1 employs a multi-layered protection design.
