Description

Technical Field

[0001] The utility model relates to the field of signal shielding wires, in particular to a wrapped signal shielding wire with anti-interference function. Background Art

[0002] Shielded wires are widely used in various scenarios. For example, in applications requiring high-quality and reliable signal transmission, such as the transmission of audio and video signals, the role of shielded wires is particularly important. In addition, shielded wires can also perform excellently in high-frequency interference environments, near high-voltage equipment, data transmission lines, and connecting sensitive equipment.

[0003] Currently, signal shielding cables on the market usually adopt a single-layer shielding structure during use. However, in some areas with strong signal penetration, the single-layer shielding structure cannot form a strong shield for the penetrating signal, which can easily lead to interference with the signal transmitted by the signal shielding cable in areas with strong signal penetration.

[0004] Therefore, in view of the above-mentioned areas where signal penetration is strong, the signals transmitted by the signal shielding cable will still be interfered with. A wrapped signal shielding cable with anti-interference function can be designed. By upgrading the structure of the shielding cable from a single layer to a multi-layer, and installing a storage device with anti-interference function at the outer end of the shielding cable to store excess unused shielding cables, the area where the signal is interfered with and penetrated is reduced, thereby solving the above-mentioned problem. Utility Model Content

[0005] In order to overcome the current signal shielding cables on the market, a single-layer shielding structure is usually used during use. However, in some areas with strong signal penetration, the single-layer shielding structure cannot form a strong shield for the penetrating signal, which can easily lead to the problem that the signal transmitted by the signal shielding cable will still be interfered with in areas with strong signal penetration.

[0006] The technical solution of the utility model is: a wrapped signal shielded wire with anti-interference, comprising an anti-interference storage barrel, a shielded wire body, a storage roll, a storage cover, a crank and a support frame; a storage bin is provided inside the anti-interference storage barrel, and a storage roll for storing the shielded wire is provided at the inner center of the storage bin, a storage cover is provided on one side of the anti-interference storage barrel, the storage cover is matched and snapped with the anti-interference storage barrel, a crank for driving the storage roll to rotate is provided at the outer center of the storage cover, a support frame for supporting the anti-interference storage barrel is provided below the anti-interference storage barrel, a spiral wire winding groove is provided at the outer end of the storage roll, a shielded wire body is wound around the outer end of the spiral wire winding groove, and the shielded wire body comprises a wire core, a rubber insulating sleeve, a graphene film sleeve, a primary metal mesh sleeve, a primary non-woven fabric winding sleeve, a polypropylene insulating sleeve, a secondary metal mesh sleeve, a secondary non-woven fabric winding sleeve and an outer rubber protective sleeve.

[0008] Preferably, a rubber insulating sleeve, a graphene film sleeve, a primary metal mesh sleeve, a primary non-woven fabric wrapped sleeve, a polypropylene insulating sleeve, a secondary metal mesh sleeve, a secondary non-woven fabric wrapped sleeve and an outer rubber protective sleeve are sequentially arranged along the outer end of the wire core.

[0011] Preferably, a rotating sleeve is provided between the fixed shaft and the rotating groove, the fixed shaft and the rotating groove are movably connected through the rotating sleeve, and a locking slot is provided at the other end of the storage roll.

[0012] Preferably, a turning hole is provided through the center of the storage cover, a transmission shaft is provided at one end of the turning handle, and one end of the transmission shaft is connected to the turning handle.

[0013] Preferably, the other end of the transmission shaft passes through the rotating hole and extends to the interior of the engaging slot, and the other end of the transmission shaft is provided with an engaging block corresponding to the engaging slot.

[0014] Beneficial effects of the utility model:

The present application combines a crank, a storage roll, an anti-interference storage barrel and a storage cover, so that when the shielded wire body is long, the user can turn the crank to drive the storage roll to rotate, thereby rolling up the excess shielded wire body into the anti-interference storage barrel.

[0024] See also Figure 2-Figure 3 In this embodiment, a polypropylene flexible plate 9 is fitted on the inner wall of the storage bin 2, and a wire outlet hole 12 is opened on one inner wall of the storage bin 2. A wire rack 13 is provided on the outer end of the anti-interference storage barrel 1, and a wire ring 14 corresponding to the wire outlet hole 12 is fixedly installed on one end of the wire rack 13. Through the combination of the polypropylene flexible plate 9, the wire outlet hole 12, the wire rack 13 and the wire ring 14, the polypropylene flexible plate 9 can enhance the anti-interference performance of the anti-interference storage barrel 1, and the wire rack 13 can fix the wire ring 14 at the front end of the wire outlet hole 12, so that when the shielded wire body 4 passes through the wire outlet hole 12, the wire ring 14 can play a guiding role. A rotating groove 19 is opened at the center of one end of the storage reel 3, and a fixed shaft 10 is provided at the center of one end of the storage bin 2. One end of the fixed shaft 10 extends to the inside of the rotating groove 19. Through the combination of the fixed shaft 10 and the rotating groove 19, the storage reel 3 can be movably fixed to the center of the storage bin 2 through the rotating groove 19 and the fixed shaft 10 to reel in the shielded wire body 4.

[0025] See also Figure 3-Figure 4 In this embodiment, a rotating sleeve 11 is provided between the fixed shaft 10 and the rotating groove 19, and the fixed shaft 10 and the rotating groove 19 are movably connected through the rotating sleeve 11.

[0026] See also Figure 3-Figure 5In this embodiment, the other end of the transmission shaft 16 extends through the rotating hole 6 to the inside of the snap-fitting slot 17.

At the same time, the graphene film sleeve 403, the primary metal mesh sleeve 404 and the secondary metal mesh sleeve 407 are combined, so that when the signal penetration is strong, the primary metal mesh sleeve 404 and the secondary metal mesh sleeve 407 can form a double signal shielding layer at the outer end of the wire core 401, thereby effectively blocking the penetration of the signal, and through the excellent conductive properties of the graphene film sleeve 403, the electric field is effectively evenly distributed, and the stability of the signal shielding is increased, thereby further preventing the external electromagnetic environment from interfering with the signal in the cable, and ensuring the signal transmission quality.
