Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electric power, in particular to a power-using device and a wave-absorbing cable. BACKGROUND

[0002] Cables are important electrical components for power supply and signal transmission, and are widely used in various places. When the external power environment is complex, the transmission signals in the cable are easily disturbed or affected by external electromagnetic wave signals, and at the same time, the cable itself also radiates electromagnetic waves to the outside, so the wave-absorbing cable with strong anti-electromagnetic interference performance and the ability to reduce its own interference to the environment and power supply is widely used. The traditional wave-absorbing cable has low tensile strength and is easy to be damaged during use. SUMMARY

[0003] Therefore, it is necessary to provide a power-using device and a wave-absorbing cable to solve the problem of low tensile strength and easy damage.

[0004] The technical scheme is as follows:

[0005] In one aspect, a wave-absorbing cable is provided, comprising:

[0006] a shielding outer skin, the shielding outer skin being provided with an inner cavity;

[0007] at least three core wires, each of the at least three core wires being arranged in the inner cavity, an outer side wall of each of the core wires being tangentially arranged with an inner side wall of the inner cavity, and outer side walls of two adjacent core wires being tangentially arranged and surrounded by the inner side wall of the inner cavity to form a first filling space; and

[0008] at least three first wave-absorbing wires, each of the at least three first wave-absorbing wires being correspondingly arranged in the at least three first filling spaces, and an outer side wall of each of the first wave-absorbing wires being tangentially arranged with the outer side walls of the two adjacent core wires and the inner side wall of the inner cavity.

[0009] The technical scheme is further described as follows:

[0010] In one embodiment, the outer side walls of the at least three core wires surround a second filling space, and the wave-absorbing cable further comprises a second wave-absorbing wire, the second wave-absorbing wire being arranged in the second filling space, and an outer side wall of the second wave-absorbing wire being tangentially arranged with the outer side wall of each of the core wires.

[0011] In one embodiment, the outer side walls of the at least three core wires surround a third filling space, and the wave-absorbing cable further comprises an intermediate support, the intermediate support being arranged in the third filling space, and an outer contour of the intermediate support matching a contour of the third filling space.

[0012] In one of the embodiments, the intermediate support comprises a wave-absorbing support.

[0013] In one of the embodiments, the core wire is three, and the three core wires are distributed in a triangle in the inner cavity and form three first filling spaces, and the first wave-absorbing wire is three, and the three first wave-absorbing wires are arranged in the three first filling spaces one by one, and the outer side wall of each first wave-absorbing wire is arranged tangentially to the inner side wall of the corresponding first filling space.

[0014] In one of the embodiments, the core wire is four, and the four core wires are distributed in a rectangle in the inner cavity and form four first filling spaces, and the first wave-absorbing wire is four, and the four first wave-absorbing wires are arranged in the four first filling spaces one by one, and the outer side wall of each first wave-absorbing wire is arranged tangentially to the inner side wall of the corresponding first filling space.

[0015] In one of the embodiments, the cross section of the core wire and the first wave-absorbing wire is circular.

[0016] In one of the embodiments, the shielding outer skin comprises an insulating sheath and a shielding layer, the insulating sheath is sleeved on the outer side wall of the shielding layer, and the shielding layer is provided with the inner cavity.

[0017] In one of the embodiments, the shielding layer comprises at least one of iron foil ring, aluminum foil ring or copper foil ring.

[0018] On the other hand, a kind of electrical equipment is provided, comprising at least two electrical devices and at least one wave-absorbing cable, and at least two electrical devices are electrically connected by the wave-absorbing cable.

[0019] In the electrical equipment and absorbing cable described above, electromagnetic interference from the outside is reflected by the shielding outer sheath, preventing the core wire from being interfered with or affected by the outside. Signal transmission is accurate. Even if a small amount of electromagnetic interference enters the inner cavity, it can be absorbed by the first absorbing line, preventing electromagnetic interference. Simultaneously, during the radiation of electromagnetic interference from the core wire itself towards the outside, part is directly absorbed by the first absorbing line within the inner cavity, and the other part is completely absorbed by the first absorbing line after multiple reflections by the shielding outer sheath within the inner cavity. Ordinary insulating materials can be used for the insulating outer sheath; there is no need to use absorbing materials, thus avoiding interference with signal transmission. Furthermore, since the thermal conductivity of the first absorbing line is an order of magnitude higher than that of air, using at least three first absorbing lines can also serve as heat conduction paths for at least three core wires, dissipating the heat from the core wires to the outside. This avoids the risk of short circuits caused by overheating in the absorbing cable, resulting in high safety performance. The outer wall of each core wire is tangent to the inner wall of the cavity; and the first absorbing wire in each first filling space is tangent to both the inner wall of the cavity and the outer wall of the core wire, that is, the first absorbing wire is tangent to the inner wall of the first filling space; the first absorbing wire does not fill the first filling space, which can reduce the weight of the absorbing cable and reduce manufacturing costs. Moreover, when the absorbing cable is pulled and stretched, the first absorbing wire, the core wire and the shielding sheath can move relative to each other in the radial direction of the cavity, resulting in high tensile strength and preventing damage.

[0026] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] In one embodiment, an electrical device is provided, including at least two electrical components and at least one microwave absorbing cable 10, thereby electrically connecting the various electrical components using the microwave absorbing cable 10 to achieve the transmission of electrical energy or the transmission of signals.

[0028] Among them, the electrical device can be any existing device that needs to transmit electrical energy or signals.

[0029] like Figure 1 and Figure 2 As shown, optionally, the absorbing cable 10 includes a shielding outer sheath 100, at least three core wires 200 and at least three first absorbing wires 300.

[0030] The shielding outer sheath 100 has an inner cavity 130. The shielding outer sheath 100 can wrap the core wire 200, which can not only prevent the core wire 200 from being corroded by foreign objects, but also reflect external interference signals to achieve the shielding effect.

[0031] At least three core wires 200 are disposed within the inner cavity 130. Furthermore, the outer sidewall of each core wire 200 is tangential to the inner sidewall of the inner cavity 130, thereby enabling the core wire 200 to move relative to the shielding sheath 100 in the radial direction of the inner cavity 130.

[0032] Furthermore, the outer walls of two adjacent core wires 200 are tangentially arranged and enclose the inner wall of the inner cavity 130 to form a first filling space 131, thereby forming at least three first filling spaces 131.

[0033] It should be noted that those skilled in the art will understand that the core wire 200 can be any existing cable capable of transmitting electrical energy or signals, and may specifically include an insulating outer sheath 210 and a metal inner core 220.

[0034] At least three first absorbing wires 300 are disposed in at least three first filling spaces 131, one-to-one. Furthermore, the outer wall of each first absorbing wire 300 is tangentially disposed to the outer walls of the two adjacent core wires 200 and the inner wall of the inner cavity 130, thereby enabling both the first absorbing wire 300 and the core wire 200 to move relative to the shielding sheath 100 in the radial direction of the inner cavity 130, and also enabling relative movement between the first absorbing wire 300 and the core wire 200 in the radial direction of the inner cavity 130.

[0035] Optionally, the first absorbing line 300 can be made of any existing absorbing material, and no limitation is made here.

[0036] In the above embodiment of the absorbing cable 10, electromagnetic interference from the outside is reflected by the shielding outer sheath 100, preventing the core wire 200 from being interfered with or affected by the outside, and the signal can be transmitted accurately. Even if a small amount of electromagnetic interference enters the inner cavity 130, it can be absorbed by the first absorbing wire 300 to avoid electromagnetic interference.

[0037] In a traditional type of electromagnetic wave absorbing cable 10, to achieve the wave absorption effect, an outer sheath made of wave-absorbing material is used to wrap a metal inner core 220. Due to the reflection effect of the wave-absorbing material on electromagnetic waves, the electromagnetic interference of the metal inner core 220 is confined within the outer sheath, forming a waveguide-like effect. This causes some interference to be transmitted to the terminal and ultimately emitted outward, interfering with the normal transmission of signals. In the above embodiment of the electromagnetic wave absorbing cable 10, during the radiation of electromagnetic interference from the core wire 200 itself towards the outside, part of it is directly absorbed by the first wave-absorbing line 300 within the inner cavity 130, and the other part is completely absorbed by the first wave-absorbing line 300 after multiple reflections within the inner cavity 130 by the shielding outer sheath 100. The insulating outer sheath 210 can use ordinary insulating material, without the need for wave-absorbing material, thus avoiding interference with signal transmission.

[0038] Furthermore, since the thermal conductivity of the first absorbing wire 300 is an order of magnitude higher than that of air, at least three first absorbing wires 300 can also serve as heat conduction paths for at least three core wires 200 to conduct heat out of the core wires 200, thus avoiding the risk of short circuit caused by overheating of the absorbing cable 10, resulting in high safety performance.

[0039] Traditional absorbing cables 10 fill the gap between the core wire 200 and the shielding sheath 100 with corresponding absorbing material. The core wire 200 and the absorbing material filling the entire gap fill the entire cavity 130 of the shielding sheath 100. This not only makes the absorbing cable 10 heavier and more expensive to manufacture, but also makes it more susceptible to damage due to its poor tensile strength when subjected to pulling and tugging. In the above embodiment of the microwave absorbing cable 10, the outer sidewall of each core wire 200 is tangent to the inner sidewall of the inner cavity 130; and the first microwave absorbing wire 300 in each first filling space 131 is tangent to both the inner sidewall of the inner cavity 130 and the outer sidewall of the core wire 200, that is, the first microwave absorbing wire 300 is tangent to the inner sidewall of the first filling space 131; the first microwave absorbing wire 300 does not fill the first filling space 131, which can reduce the weight of the microwave absorbing cable 10 and reduce manufacturing costs. Moreover, when the microwave absorbing cable 10 is pulled and stretched, the first microwave absorbing wire 300, the core wire 200 and the shielding outer sheath 100 can move relative to each other in the radial direction of the inner cavity 130, resulting in high tensile strength and preventing damage.

[0040] Preferably, the cross-section of the core wire 200 is circular, and the cross-section of the first absorbing wire 300 is also preferably circular. In this way, the first absorbing wire 300 is tangentially arranged with the core wire 200, so that the first absorbing wire 300 and the core wire 200 are in line contact. When the absorbing cable 10 is pulled or stretched by an external force, the first absorbing wire 300 and the core wire 200 can move relative to each other in the radial direction of the inner cavity 130, thereby buffering the impact force and preventing damage to the core wire 200 and the first absorbing wire 300.

[0041] Optionally, the outer walls of at least three core wires 200 are arranged to form a second filling space (not shown). Thus, the outer walls of at least three core wires 200 are tangent to each other and form a second filling space in the middle.

[0042] Furthermore, the electromagnetic wave absorbing cable 10 also includes a second absorbing wire (not shown). The second absorbing wire is disposed within the second filling space, and its outer wall is tangential to the outer wall of each core wire 200. This not only allows for further absorption of electromagnetic waves using the second absorbing wire, but also facilitates the transfer and dissipation of heat generated by the core wire 200. Combined with the heat transfer from the first absorbing wire 300, this provides the core wire 200 with two heat dissipation paths, resulting in better heat dissipation. Moreover, when the electromagnetic wave absorbing cable 10 is subjected to external pulling or stretching, the second absorbing wire and the core wire 200 can move relative to each other in the radial direction of the inner cavity 130, which also buffers the impact force and prevents damage to the core wire 200 and the second absorbing wire.

[0043] The second absorbing line can be made of any existing absorbing material, and there is no limitation here. The second absorbing line can be made of the same material as the first absorbing line 300.

[0044] The cross-section of the second absorbing wire is preferably circular. This arrangement, with the second absorbing wire tangent to the core wire 200, allows for more flexible relative movement between the second absorbing wire and the core wire 200 when the absorbing cable 10 is subjected to external force.

[0045] like Figure 1 and Figure 2 As shown, optionally, the outer walls of at least three core wires 200 are arranged to form a third filling space 400. Thus, the outer walls of at least three core wires 200 are tangent to each other and form a third filling space 400 in the middle.

[0046] like Figure 1 and Figure 2 As shown, the absorbing cable 10 further includes an intermediate support 500. The intermediate support 500 is disposed within the third filling space 400. Furthermore, the outer contour of the intermediate support 500 matches the contour of the third filling space 400. This increases the contact area between the intermediate support 500 and each core wire 200, allowing the heat generated by each core wire 200 to be fully transferred to the intermediate support 500 and dissipated outwards through the intermediate support 500, resulting in better heat dissipation.

[0047] Furthermore, the intermediate support 500 includes an absorbing support (not labeled). Thus, because the outer contour of the absorbing support matches the contour of the third filling space 400, the contact area between the absorbing support and the core wire 200 is large, allowing for sufficient absorption of the electromagnetic waves generated by the core wire 200. Combined with the reflection effect of the shielding outer sheath 100 on the electromagnetic waves generated by the core wire 200, the absorbing support can quickly and effectively absorb the electromagnetic waves generated by the core wire 200.

[0048] The absorbing bracket can be made of any existing absorbing material, and there are no restrictions here.

[0049] The specific number of core wires 200 and the specific number of first absorbing wires 300 used can be flexibly designed or adjusted according to actual usage needs.

[0050] like Figure 1As shown, optionally, there are three core wires 200, which are arranged in a triangle within the inner cavity 130 to form three first filling spaces 131. There are also three first absorbing wires 300, which are correspondingly positioned within the three first filling spaces 131. Furthermore, the outer wall of each first absorbing wire 300 is tangent to the inner wall of the corresponding first filling space 131. Thus, with the three core wires 200 and three first absorbing wires 300 positioned within the inner cavity 130, and the outer walls of adjacent core wires 200 tangent to the first absorbing wires 300 within the corresponding first filling space 131, when the absorbing cable 10 is subjected to external force, the three first absorbing wires 300 and the three core wires 200 move relative to each other in the radial direction of the inner cavity 130. This buffers the impact force and prevents damage to the core wires 200 and the first absorbing wires 300.

[0051] like Figure 2 As shown, optionally, there are four core wires 200, which are rectangularly distributed within the inner cavity 130 to form four first filling spaces 131. There are also four first absorbing wires 300, each corresponding to one of the four first filling spaces 131. Furthermore, the outer wall of each first absorbing wire 300 is tangent to the inner wall of the corresponding first filling space 131. Thus, with the four core wires 200 and four first absorbing wires 300 positioned within the inner cavity 130, and the outer walls of adjacent core wires 200 tangent to the first absorbing wires 300 within their respective first filling spaces 131, when the absorbing cable 10 is subjected to external force, the four first absorbing wires 300 and the four core wires 200 move relative to each other in the radial direction of the inner cavity 130. This buffers the impact force and prevents damage to the core wires 200 and the first absorbing wires 300.

[0052] The shielding outer sheath 100 can not only provide insulation protection for the core wire 200 inside the inner cavity 130, but also reflect and shield against external electromagnetic interference. Furthermore, it can reflect the battery waves generated by the core wire 200 itself inside the inner cavity 130 so that the first absorbing wire 300 can fully absorb them and avoid electromagnetic pollution.

[0053] like Figure 1 and Figure 2As shown, optionally, the shielding outer sheath 100 includes an insulating sheath 110 and a shielding layer 120. The insulating sheath 110 is fitted onto the outer wall of the shielding layer 120. Thus, the insulating sheath 110 provides insulation protection for the core wire 200, preventing safety accidents such as leakage. The shielding layer 120 has an inner cavity 130. Thus, the first absorbing wire 300 and the core wire 200 are placed within the inner cavity 130. The shielding layer 120 can reflect and shield external electromagnetic interference. Furthermore, the shielding layer 120 can also reflect the electromagnetic waves generated by the core wire 200 itself within the inner cavity 130, allowing the first absorbing wire 300 to fully absorb them and preventing electromagnetic pollution.

[0054] Optionally, the shielding layer 120 includes at least one of an iron foil ring, an aluminum foil ring, or a copper foil ring, thus forming a metallic shielding space with good shielding effect.

[0055] Alternatively, the insulating sheath 110 may be made of insulating materials such as rubber or silicone.
