Description

Technical Field

[0001] This invention relates to the technical field of communication cable structures, and specifically to an anti-interference communication cable and its sheath installation method. Background Technology

[0002] PoE technology in digital communication cables refers to the ability to provide DC power to IP terminals, such as IP phones, wireless LAN access points (APs), and network cameras, while transmitting data signals without any changes to the existing Ethernet infrastructure.

[0003] With the continuous advancement of science and technology, the speed of cable power supply and communication transmission also needs to be higher and faster, thus requiring an increase in the operating power of the equipment. In 2011, Cisco increased the operating power of the equipment to 60W; in 2018, the TEEE 802.3bt standard was released, adding Class 5 to Class 8 classifications, with the maximum power of the PD reaching 71.3W. If the line length is known, the maximum power of the PD can be increased to 90W.

[0004] This shows that as the operating power of the equipment increases, high-power power supply will cause the cable temperature to rise significantly, thereby reducing the transmission performance of the cable and even accelerating the aging of the cable. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, the purpose of this invention is to provide an anti-interference communication cable and its sheath installation method, which can effectively buffer the cable temperature rise problem caused by the increase in power during cable operation.

[0006] The objective of this invention is achieved through the following technical solution:

[0007] An anti-interference communication cable includes an outer sheath with a heat dissipation section on its inner circumferential surface, a frame and several conductors disposed inside the outer sheath, the conductors being separated by the frame, the surface of the conductors being wrapped with an insulation layer, a heat transfer element being detachably connected to the frame, the heat transfer element being located between the conductors and the heat dissipation section, and the heat dissipation section on the inner circumferential surface of the outer sheath being directly opposite the heat transfer element.

[0008] Furthermore, the skeleton is strip-shaped, and its length direction is consistent with the length direction of the conductor. The cross-section of the skeleton is cross-shaped, and the four ends of the cross-section of the skeleton are close to the inner circumferential surface of the outer sheath. The skeleton forms four spacer grooves between its cross-sectional shape and the inner circumferential surface of the outer sheath, and a plurality of the conductors are equally distributed in the four spacer grooves.

[0009] Furthermore, each of the four ends of the cross-section of the skeleton is integrally connected with a bidirectional hook block. The two hook ends of the bidirectional hook block are respectively positioned facing the two adjacent spacer slots. The heat transfer element is disposed between two adjacent ends in the cross-section of the skeleton. The heat transfer element includes a heat-conducting strip whose length direction is consistent with the length direction of the skeleton. The cross-section of the heat-conducting strip is strip-shaped. The cross-sectional length of the heat-conducting strip is equal to the distance between two adjacent ends in the cross-section of the skeleton. Furthermore, both ends of the heat-conducting strip along its cross-sectional length direction are integrally connected with connecting hooks, which are hooked and engaged with the hook ends of the bidirectional hook block.

[0010] Furthermore, each of the aforementioned slots contains two wires. The inner corners between adjacent ends of the skeleton are rounded, and the radius of curvature of the inner circumferential surface of the rounded corner is consistent with the radius of curvature of the outer circumferential surface of the insulation layer of the wire. The heat-conducting strip is integrally connected to a limiting slot on its side facing the slot. The limiting slot extends along the length of the heat-conducting strip. The outer circumferential surface of the insulation layer of one of the wires in the slot is in contact with the inner circumferential surface of the rounded corner in the slot. The other wire is confined within the limiting slot by its insulation layer, and the wire abuts against the inner wall of the limiting slot. The two wires abut against each other.

[0011] Furthermore, the heat dissipation part includes a serrated surface disposed on the inner circumferential surface of the outer sheath, the length direction of the serrated surface is consistent with the length direction of the outer sheath, and a plurality of serrated surfaces are evenly distributed along the circumferential direction about the axis of the outer sheath.

[0012] Furthermore, the outer sheath has a heat dissipation hole through its end face along the length direction. The heat dissipation hole is located between the inner and outer circumferential surfaces of the outer sheath. The outer circumferential surface of the outer sheath has a plurality of connecting holes that are connected to the heat dissipation hole. The plurality of connecting holes corresponding to the same heat dissipation hole are arranged at intervals along the depth direction of the heat dissipation hole.

[0013] Furthermore, the outer peripheral surface of the outer sheath is provided with a heat-conducting layer, and a straight groove is formed on the outer peripheral surface of the outer sheath. The straight groove extends through the outer sheath along its length. A straight strip protrudes from the inner peripheral surface of the heat-conducting layer. The straight strip extends along the length of the heat-conducting layer and is inserted into the straight groove. An assembly hole is formed on the outer peripheral surface of the heat-conducting layer, and the assembly hole is directly opposite the connection hole.

[0014] Furthermore, the number of heat dissipation holes is multiple, and several of the heat dissipation holes are equally spaced along the circumferential direction about the axis of the outer sheath. The cross-section of the heat dissipation hole is waist-shaped, and the length direction of the cross-section of the heat dissipation hole is consistent with the circumferential extension direction of the outer sheath.

[0015] Furthermore, the cross-section of the insulation layer of the conductor is honeycomb-shaped.

[0016] A method for installing the sheath of an anti-interference communication cable includes the following steps:

[0017] Internal sheathing: Connect the two connecting hooks of the heat-conducting strip to the hook ends of the two bidirectional hook blocks at the adjacent ends of the frame. Face the limiting groove of the heat-conducting strip into the interval groove, and then insert two wires into each interval groove. The two guides abut against each other, and one wire abuts against the inner surface of the rounded corner through the insulation layer. The other wire is restricted in the limiting groove through the insulation layer and abuts against the inner wall of the limiting groove through the insulation layer. Repeat this operation to complete the installation of the wires in each interval groove of the frame, thereby forming the cable core.

[0018] External sheath: An outer sheath is die-cast onto the surface of the cable core, so that the serrated surface of the outer sheath faces the cable core and is directly opposite the heat-conducting strip of the cable core. Then, a cutting process is used to push the roller to cut a straight groove on the surface of the outer sheath with a cutter. The cutting direction extends along the length of the outer sheath. Then, the heat-conducting layer is applied to the surface of the outer sheath, and its mounting holes correspond to the connection holes.

[0019] Water-cooled jacket: Water pipe interfaces are connected to the assembly holes at intervals along the depth direction of the heat dissipation holes to inject coolant into the heat dissipation holes. At the same time, some of the spaced-out assembly holes are suspended to facilitate the discharge of the high-temperature coolant in the heat dissipation holes, so as to achieve the functions of continuous cooling and water-cooled jacket.

[0020] The present invention has the following beneficial effects:

[0021] An anti-interference communication cable is designed to effectively buffer the cable temperature rise caused by increased power during operation. Therefore, by incorporating a frame and multiple conductors within the outer sheath, the frame separates the conductors, effectively isolating heat radiation generated by adjacent conductors during operation and reducing the possibility of adjacent conductors becoming heat sources for each other. Simultaneously, by applying an insulation layer to the surface of the conductors, interference between the transmitted current signal and external sources is reduced, thereby improving signal stability. Furthermore, by detachably installing a heat transfer element on the frame and positioning it between the conductors and the heat dissipation section, the conductors can rapidly absorb heat through the heat transfer element when operating and generating heat. The heat is then cooled by the heat dissipation section of the outer sheath. This effectively buffers the temperature rise of the conductors, reducing damage and shortening their lifespan caused by overheating.

[0022] An anti-interference communication cable sheath installation method mainly consists of three steps: internal sheathing, external sheathing, and water-cooled sheathing. The internal sheathing primarily involves placing insulated conductors within the spacers of the cable frame, while detachably installing heat-conducting strips between adjacent ends of the frame, thus forming the cable core. During operation, the heat generated by the conductors is transferred to the heat-conducting strips, improving heat dissipation efficiency and compensating for additional cable attenuation caused by temperature rise. The external sheath consists of an outer sheath and a heat-conducting layer on the outer surface of the cable core. The serrated surface and ventilation holes on the outer sheath increase convection space, while the ventilation holes allow for heat dissipation through air transfer. The heat-conducting layer absorbs heat from the outer sheath surface, further improving heat dissipation efficiency and compensating for additional cable attenuation caused by temperature rise. Additionally, water-cooled sheathing involves connecting water pipes to the mounting holes at intervals to allow coolant to be introduced into the heat dissipation holes. The coolant is used to quickly cool the cable core during operation, while the empty mounting holes allow the cooled coolant to drain out. This ensures that most of the coolant in the heat dissipation holes remains at a relatively cool temperature, thereby improving the efficiency of cooling the cable core and mitigating the additional attenuation caused by temperature rise in the cable.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. Terms such as “upper,” “inner,” “middle,” “left,” “right,” and “one” used in this specification are merely for clarity of description and are not intended to limit the scope of the invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention.

[0031] Reference Figures 1 to 6 As shown, an anti-interference communication cable includes an outer sheath 1 with a heat dissipation part on its inner circumferential surface. The outer sheath 1 contains a frame 3 and several conductors 5, which are separated by the frame 3. The surface of the conductors 5 is covered with an insulation layer 51. The frame 3 is detachably connected to a heat transfer element, which is located between the conductors 5 and the heat dissipation part. The heat dissipation part on the inner circumferential surface of the outer sheath 1 is directly opposite the heat transfer element.

[0032] Specifically, this invention aims to effectively buffer the cable temperature rise problem caused by increased power during cable operation. Therefore, by setting a frame 3 and multiple conductors 5 inside the outer sheath 1, the frame 3 separates the multiple conductors 5, effectively isolating the heat radiation generated by adjacent conductors 5 during operation, thus reducing the possibility of adjacent conductors 5 becoming heat sources for each other. Simultaneously, by setting an insulation layer 51 on the surface of the conductors 5, interference between the transmitted current signal and external sources is reduced, thereby improving the stability of the transmitted signal. Furthermore, by detachably installing a heat transfer element on the frame 3 and positioning it between the conductors 5 and the heat dissipation section, when the conductors 5 are operating and generating heat, they can quickly absorb heat using the heat transfer effect of the heat transfer element, and then cool the heat from the heat transfer element through the heat dissipation section of the outer sheath 1. This effectively buffers the temperature rise of the conductors 5 using the heat dissipation section of the outer sheath 1, thereby reducing damage and reduced service life caused by temperature rise.

[0033] Reference Figures 1 to 6As shown, to achieve the function of spacing multiple conductors 5 between each other using the frame 3, the frame 3 is strip-shaped, with its length direction aligned with the length direction of the conductors 5. The cross-section of the frame 3 is cross-shaped, with all four ends of the cross-section approaching the inner circumferential surface of the outer sheath 1. The frame 3 forms four spacing slots 32 between its cross-section and the inner circumferential surface of the outer sheath 1, and a number of conductors 5 are equally distributed within the four spacing slots 32. Specifically, by setting the frame 3 with a cross-shaped cross-section, four spacing slots 32 are formed at equal angles about the axis. The spacing slots 32 facilitate the placement of a specified number of conductors 5 within them. The isolation effect of the ends of the frame 3's cross-section reduces the heat radiation of conductors 5 from adjacent spacing slots 32 during operation, thus minimizing its impact on the conductors 5 in adjacent spacing slots 32. Furthermore, the cross-shaped cross-section of the frame 3 provides optimal installation space for the conductors 5, thereby simplifying installation operations.

[0034] To ensure the heat transfer element effectively absorbs and transfers heat, and to allow for detachable connection between the heat transfer element and the frame 3, a bidirectional hook block 31 is integrally connected to each of the four ends of the frame 3's cross-section. The two hook ends of the bidirectional hook block 31 face adjacent slots 32, and the hook openings of the hook ends of the bidirectional hook block 31 face into the slots 32. The heat transfer element is positioned between two adjacent ends of the frame 3's cross-section. The heat transfer element includes a heat-conducting strip 4 whose length direction is aligned with the length direction of the frame 3. The heat-conducting strip 4 has an arc-shaped cross-section, and its cross-sectional length is equal to the distance between two adjacent ends of the frame 3's cross-section. Connecting hooks 41 are integrally connected to both ends of the heat-conducting strip 4 along its cross-sectional length direction. After the connecting hooks 41 engage with the hooks of the bidirectional hook blocks 31, the heat-conducting strip 4 is inserted along the length direction of the frame 3, aligning its ends with the ends of the frame 3. Among them, the heat-conducting strip 4 has good thermal conductivity and can quickly transfer heat energy. The heat-conducting strip 4 can be made of metal materials with good thermal conductivity, such as metal steel, metal copper, and metal chromium. The metal strip is in sheet shape, which has the function of quick and easy processing.

[0035] Specifically, by setting a bidirectional hook block 31 at the end of the frame 3, the heat-conducting strip 4 can hook and engage with the hook part of the bidirectional hook block 31 through its connecting hook 41, thereby realizing the function of detachable connection of the heat-conducting strip 4. This allows the spacer groove 32 of the frame 3 and the heat-conducting strip 4 to directly form a space for the installation of the wire 5. As a result, after the wire 5 in the spacer half heats up during operation, it can directly contact the heat-conducting strip 4 and directly absorb the heat of the wire 5 through the heat-conducting strip 4, and then dissipate the heat through the heat dissipation part of the outer sheath 1 to achieve rapid cooling.

[0036] Since cables typically involve signal input and output when transmitting information, cable conductors 5 are usually presented in the form of wire pairs. Therefore, in order to allow two conductors 5 of a wire pair to be placed in the spacer slot 32 of the frame 3, and to keep the two conductors 5 in the spacer slot 32 in a relatively fixed state. Therefore, the structure of the spacer groove 32 and the heat-conducting strip 4 is defined as follows: the number of wires 5 in each spacer groove 32 is two, and the inner corners between adjacent ends of the skeleton 3 are provided with rounded corners 33. The radius of curvature of the inner circumferential surface of the rounded corner 33 is consistent with the radius of curvature of the outer circumferential surface of the insulation layer 51 of the wire 5. The side of the heat-conducting strip 4 facing the spacer groove 32 is integrally connected to the limiting slot 43. The limiting slot 43 extends along the length of the heat-conducting strip 4. The outer circumferential surface of the insulation layer 51 of one wire 5 in the spacer groove 32 is in contact with the inner circumferential surface of the rounded corner 33 in the spacer groove 32. The other wire 5 is limited in the limiting slot 43 by its insulation layer 51, and the wire 5 abuts against the inner wall of the limiting slot 43. The two wires 5 abut against each other.

[0037] Specifically, a rounded corner 33 is provided within the spacer groove 32, and a limiting slot 43 is provided on the side of the heat-conducting strip 4 facing the spacer groove 32. This limiting slot 43 is formed by integrally connecting the opening limiting block 42 to the side of the outer heat-conducting strip 4 facing the spacer groove 32. Simultaneously, the distance between the bottom surface of the rounded corner 33 and the bottom surface of the limiting slot 43 is limited to twice the cross-sectional diameter of the conductor 5 with the insulating layer 51 on its surface. Therefore, when a pair of conductors 5 is installed within the spacer groove 32, the rounded corner 33 and the limiting slot 43 effectively restrict the movement of the two conductors 5 and confine the specified conductor 5 to a defined position, facilitating troubleshooting during maintenance and allowing for easy location of the required conductor 5 during upkeep. Furthermore, since the conductors 5 placed within the spacer groove 32 are in pairs, this pair of conductors 5 is used for signal input and output. By utilizing the shape characteristics of the cross-section of the skeleton 3, signal crosstalk between adjacent pairs of conductors 5 can be effectively reduced, thereby improving the cable signal transmission efficiency.

[0038] Reference Figures 1 to 6 As shown, to achieve the function of heat dissipation for the heat-conducting strip 4 and the conductor 5, the heat dissipation unit includes a serrated surface 11 disposed on the inner circumferential surface of the outer sheath 1. The length direction of the serrated surface 11 is consistent with the length direction of the outer sheath 1, and several serrated surfaces 11 are evenly distributed around the axis of the outer sheath 1 along the circumferential direction. By providing the serrated surface 11 on the inner circumferential surface of the outer sheath 1, the inner circumferential surface area of ​​the outer sheath 1 is increased, thereby expanding the convection space of the internal conductor 5 and the heat-conducting strip 4, which is beneficial to improving heat dissipation efficiency and can compensate for the additional attenuation caused by the temperature rise of the cable.

[0039] To further enhance the heat dissipation function of the outer sheath 1 for the internal conductors 5 and heat-conducting strips 4, a heat dissipation hole 12 is provided through the end face of the outer sheath 1 along its length. The heat dissipation hole 12 is located between the inner and outer circumferential surfaces of the outer sheath 1. Several connecting holes 13 are provided on the outer circumferential surface of the outer sheath 1, and the connecting holes 13 are connected to the heat dissipation holes 12. Multiple connecting holes 13 corresponding to the same heat dissipation hole 12 are arranged at intervals along the depth direction of the heat dissipation hole 12. Specifically, in this embodiment, the connecting holes 13 are used to connect to the connectors of water pipes. Therefore, in the actual heat dissipation process, the connectors of water pipes can be installed at intervals on multiple connecting holes 13 to inject coolant into the connecting holes 13, thereby achieving the function of cooling the conductors 5 and heat-conducting strips 4 inside the cable by water cooling. At the same time, since the connectors are connected to the connecting holes 13 at intervals, the coolant that has been heated by heat exchange in the heat dissipation holes 12 can be discharged from the empty connecting holes 13, thereby achieving the function of coolant fluid circulation and efficient cooling.

[0040] To reduce the risk of wear on the surface of the outer sheath 1 and damage to the connection hole 13, preventing the installation of the connector, it is necessary to protect the surface of the outer sheath 1. Simultaneously, to further transfer the heat generated within the heat dissipation holes 12 of the outer sheath 1 outwards, thereby rapidly reducing the temperature of the internal conductor 5 of the cable, a heat-conducting layer 2 is fitted onto the outer circumferential surface of the outer sheath 1. A straight groove 14 is formed on the outer circumferential surface of the outer sheath 1, extending and penetrating along the length of the outer sheath 1. A straight strip 22 protrudes from the inner circumferential surface of the heat-conducting layer 2, extending along the length of the heat-conducting layer 2 and interlocking with the straight groove 14. This improves the stability of the heat-conducting layer 2 during installation and reduces rotation on the surface of the outer sheath 1. The outer peripheral surface of the heat-conducting layer 2 is provided with an assembly hole 21, which is directly opposite to the connection hole 13. In this embodiment, the assembly hole 21 can also be used for the connection of the water pipe joint. Therefore, in actual use, the water pipe joint can be connected to the assembly hole 21. When the surface of the heat-conducting layer 2 is damaged, the water pipe joint can be connected to the exposed connection hole 13, thereby realizing the function of inputting coolant into the heat dissipation hole 12.

[0041] To ensure optimal heat dissipation from the multiple wires 5 and heat-conducting strips 4 within the outer sheath 1, the heat dissipation holes 12 are arranged in a plurality, evenly spaced along the circumferential direction about the axis of the outer sheath 1. The cross-section of each heat dissipation hole 12 is waist-shaped, with its length aligned with the annular extension direction of the outer sheath 1. This arrangement allows the heat dissipation holes 12 to face the heat-conducting strips 4 and / or wires 5 with a larger surface area. Furthermore, the annular arrangement of the multiple heat dissipation holes 12 effectively improves heat dissipation and efficiency.

[0042] In order to dissipate heat from the conductor 5 and reduce insulation loss and signal attenuation, the insulation layer 51 of the conductor 5 has a honeycomb cross-section.

[0043] Based on the above-mentioned structure of the anti-interference communication cable, the following method for assembling the cable's sheath is disclosed:

[0044] A method for installing the sheath of an anti-interference communication cable includes the following steps:

[0045] Internal sheathing: Connect the two connecting hooks 41 of the heat-conducting strip 4 to the hook ends of the two bidirectional hook blocks 31 at the adjacent ends of the frame 3 respectively. Face the limiting groove 43 of the heat-conducting strip 4 into the interval groove 32. Then, put two wires 5 into each interval groove 32 and abut against each other. One wire 5 abuts against the inner surface of the rounded corner 33 through the insulation layer 51, and the other wire 5 is restricted in the limiting groove 43 through the insulation layer 51 and abuts against the inner wall of the limiting groove 43 through the insulation layer 51. The installation of wires 5 in each interval groove 32 in the frame 3 is completed in this way, thereby forming the cable core.

[0046] External sheath: An outer sheath 1 is die-cast onto the surface of the cable core, such that the serrated surface 11 of the outer sheath 1 faces the cable core and is directly opposite the heat-conducting strip 4 of the cable core. Then, a cutting process is used to push the roller to cut a straight groove 14 on the surface of the outer sheath 1, with the cutting direction extending along the length of the outer sheath 1. Then, the heat-conducting layer 2 is fitted onto the surface of the outer sheath 1, and its mounting hole 21 corresponds to the connection hole 13.

[0047] Water-cooled jacket: Water pipe interfaces are connected to the mounting holes 21 at intervals along the depth direction of the heat dissipation holes 12 to inject coolant into the heat dissipation holes 12. At the same time, some of the spaced mounting holes 21 are suspended to facilitate the discharge of the high-temperature coolant in the heat dissipation holes 12, so as to achieve continuous cooling and water-cooled jacket function.

[0048] Specifically, the cable sheathing method of the present invention mainly consists of three steps: internal sheathing, external sheathing, and water-cooled sheathing. Internal sheathing involves placing the conductor 5 with insulation layer 51 within the spacer groove 32 of the frame 3, and detachably installing heat-conducting strips 4 between adjacent ends of the frame 3, thereby forming the cable core. During operation, the temperature rise of the conductor 5 is transferred to the heat-conducting strips 4 to improve the heat dissipation efficiency of the conductor 5 and compensate for the additional attenuation caused by temperature rise in the cable. External sheathing involves setting an outer sheath 1 and a heat-conducting layer 2 on the outer surface of the cable core. Due to the serrated surface 11 and heat dissipation holes 12 on the outer sheath 1, the serrated surface 11 increases convection space, while the heat dissipation holes 12 facilitate heat dissipation through air transfer. The heat-conducting layer 2 absorbs heat from the surface of the outer sheath 1, thereby improving heat dissipation efficiency and compensating for the additional attenuation caused by temperature rise in the cable. Additionally, the water-cooled sheath consists of connectors for water pipes that are intermittently connected to the mounting holes 21 to allow coolant to be introduced into the heat dissipation holes 12. The coolant is used to quickly cool the cable core when the conductor 5 is in operation. The empty mounting holes 21 allow the coolant that has undergone heat exchange to be discharged, thereby ensuring that most of the coolant in the heat dissipation holes 12 remains at a relatively cool temperature. This improves the efficiency of heat dissipation and cooling of the cable core and improves the compensation for the additional attenuation caused by the temperature rise of the cable.

[0049] The embodiments of the present invention are not limited thereto. Based on the above description of the present invention, and using common technical knowledge and conventional means in the field, the present invention can be modified, replaced or combined in various other forms without departing from the basic technical idea of ​​the present invention, and all such modifications, replacements or combinations fall within the scope of protection of the present invention.

5. The anti-interference communication cable as described in claim 2, characterized in that: The cross-section of the insulation layer of the conductor is honeycomb-shaped.

6. A method for installing the sheath of an anti-interference communication cable as described in any one of claims 2 to 5, characterized in that, Includes the following steps: Internal sheathing: Connect the two connecting hooks of the heat-conducting strip to the hook ends of the two bidirectional hook blocks at the adjacent ends of the frame. Face the limiting groove of the heat-conducting strip into the interval groove, and then insert two wires into each interval groove. The two guides abut against each other, and one wire abuts against the inner surface of the rounded corner through the insulation layer. The other wire is restricted in the limiting groove through the insulation layer and abuts against the inner wall of the limiting groove through the insulation layer. Repeat this operation to complete the installation of the wires in each interval groove of the frame, thereby forming the cable core. External sheath: An outer sheath is die-cast onto the surface of the cable core, so that the serrated surface of the outer sheath faces the cable core and is directly opposite the heat-conducting strip of the cable core. Then, a cutting process is used to push the roller to cut a straight groove on the surface of the outer sheath with a cutter. The cutting direction extends along the length of the outer sheath. Then, the heat-conducting layer is applied to the surface of the outer sheath, and its mounting holes correspond to the connection holes. Water-cooled jacket: Water pipe interfaces are connected to the assembly holes at intervals along the depth direction of the heat dissipation holes to inject coolant into the heat dissipation holes. At the same time, some of the spaced-out assembly holes are suspended to facilitate the discharge of the high-temperature coolant in the heat dissipation holes, so as to achieve the functions of continuous cooling and water-cooled jacket.
