[0053] like Figure 1 As shown, a heat dissipation mechanism 100 according to an embodiment of the present invention is used to dissipate heat for a unit requiring heat dissipation.

[0054] The heat dissipation demand unit comprises an inner heat dissipation demand component and an outer sleeve 300 sleeved on the inner heat dissipation demand component 200 , and an assembly gap is provided between the outer sleeve 300 and the inner heat dissipation demand component 200 .

[0055] Specifically, the internal heat dissipation requiring component 200 can be a tubular structure, a cylindrical structure, a columnar structure or a wire; the outer sleeve 300 is used to be mounted on the outside of the internal heat dissipation requiring component 200, and there is an assembly gap between at least part of the inner wall of the outer sleeve 300 and at least part of the outer wall of the internal heat dissipation requiring component 200, and the assembly gap is used for the installation of the heat dissipation mechanism 100, thereby improving the heat dissipation effect of the internal heat dissipation requiring component 200.

[0056] Combination Figure 1 and Figure 2 The heat dissipation mechanism 100 includes an inner heat dissipation sleeve 110 , an outer heat dissipation sleeve 120 , a heat conducting member 130 and an elastic member 140 .

[0057] The inner heat dissipation sleeve 110 is used to be sleeved on the outer side of the inner heat dissipation requirement component 200 , and the inner side wall of the inner heat dissipation sleeve 110 is in contact with the outer side wall of the inner heat dissipation requirement component 200 .

[0058] It should be noted that the inner heat dissipation sleeve 110 is made of heat-conducting material, such as copper, graphite or phase change material. The inner wall of the inner heat dissipation sleeve 110 is in contact with the outer wall of the inner heat dissipation requirement part 200, and heat can be transferred between the inner heat dissipation requirement part 200 and the inner heat dissipation sleeve 110.

[0059] Of course, in other embodiments, the inner wall of the inner heat dissipation sleeve 110 may also be attached with a first heat conductive layer, and the first heat conductive layer is used to fit with the outer wall of the inner heat dissipation requirement component 200. The material of the first heat conductive layer may also be copper, graphite or phase change material.

[0060] like Figures 1 to 3 As shown, the outer heat dissipation sleeve 120 includes a plurality of outer heat dissipation plates 1201, which are arranged at intervals along the circumference of the inner heat dissipation sleeve 110, and each outer heat dissipation plate 1201 has a heat dissipation gap with the inner heat dissipation sleeve 110, and the outer wall of the outer heat dissipation sleeve 120 is used to fit with the inner wall of the outer jacket body 300.

[0061] Specifically, the outer heat dissipation sleeve 120 is made of a heat-conducting material, such as copper, graphite or phase change material. Specifically, each outer heat dissipation plate 1201 is made of a heat-conducting material. Multiple outer heat dissipation plates 1201 are arranged at intervals along the circumference of the inner heat dissipation sleeve 110 to form a sleeve-like structure, and multiple outer heat dissipation plates 1201 surround the inner heat dissipation sleeve 110; specifically, each outer heat dissipation plate 1201 is an arc-shaped plate, and the inner side wall of each outer heat dissipation plate 1201 is arranged toward the inner heat dissipation sleeve 110, and the axis of each outer heat dissipation plate 1201 coincides with the axis of the inner heat dissipation sleeve 110. In addition, each outer heat dissipation plate 1201 is spaced from the inner heat dissipation sleeve 110 to form a heat dissipation gap, and the outer side wall of each outer heat dissipation plate 1201 is used to fit with the inner side wall of the outer jacket 300, and heat transfer can be performed between the outer heat dissipation plate 1201 and the outer jacket 300.

[0062] Of course, in other embodiments, the outer wall of the outer heat dissipation plate 1201 may also be attached with a second heat conducting layer, and the second heat conducting layer is used to fit with the inner wall of the outer casing 300. The material of the second heat conducting layer may also be copper, graphite or phase change material.

[0063] Combination Figure 2 and Figure 3 There are multiple heat-conducting members 130 , and at least a portion of the outer heat-dissipating plates 1201 and the inner heat-dissipating sleeves 110 are connected with heat-conducting members 130 .

[0064] It can be understood that, for at least a portion of the outer heat sinks 1201, a heat conductor 130 is arranged between these outer heat sinks 1201 and the inner heat sink 110, wherein the number of heat conductors 130 between a single outer heat sink 1201 and the inner heat sink 110 may be one or more, and the heat conductor 130 is made of a heat-conducting material, such as copper, graphite or phase change material, and the heat conductor 130 can enable heat transfer between the outer heat sink 1201 and the inner heat sink 110.

[0065] Specifically in this embodiment, a heat conductor 130 is connected between all the outer heat dissipation plates 1201 and the inner heat dissipation sleeve 110 , that is, heat can be transferred between all the outer heat dissipation plates 1201 and the inner heat dissipation sleeve 110 under the action of the corresponding heat conductor 130 .

[0066] Combination Figure 2 and Figure 4 There are multiple elastic members 140 , and an elastic member 140 is abutted against each outer heat dissipation plate 1201 and the inner heat dissipation sleeve 110 . Each outer heat dissipation plate 1201 is configured to be able to move along the radial direction of the inner heat dissipation sleeve 110 .

[0067] It is understandable that the elastic member 140 can apply a radial thrust to the outer heat dissipation plate 1201 connected thereto along the inner heat dissipation sleeve 110 , so that the outer heat dissipation plate 1201 tends to move away from the inner heat dissipation sleeve 110 along the radial direction of the inner heat dissipation sleeve 110 .

[0068] The elastic member 140 may be a spring or elastic rubber.

[0069] Specifically in this embodiment, the elastic member 140 is a heat-conducting spring, which can assist in transferring heat.

[0070] When installing the heat dissipation mechanism 100 of the present invention, firstly, the inner heat dissipation sleeve 110 is sleeved on the outer side of the inner heat dissipation demanding part 200, and the inner side wall of the inner heat dissipation sleeve 110 is fitted with the outer side wall of the inner heat dissipation demanding part 200; then, a plurality of heat conducting members 130 are connected to the inner heat dissipation sleeve 110; then, a plurality of elastic members 140 are connected to the inner heat dissipation sleeve 110; and then, a plurality of outer heat dissipation plates 1201 are arranged at intervals along the circumference of the inner heat dissipation sleeve 110, and each outer heat dissipation plate 1201 is fitted with at least one elastic member 140. 0, and make at least a part of the outer heat dissipation plates 1201 connected to each heat-conducting member 130; then, apply pressure to each outer heat dissipation plate 1201 to make each outer heat dissipation plate 1201 move toward the inner heat dissipation sleeve 110, so that the outer heat dissipation sleeve 120 shrinks until the diameter of the outer heat dissipation sleeve 120 is less than or equal to the inner diameter of the outer sleeve 300, and then the outer sleeve 300 is sleeved on the outside of the heat dissipation mechanism 100, so that the outer wall of the outer heat dissipation plate 1201 fits with the inner wall of the outer sleeve 300.

[0071] It can be understood that when the inner heat dissipation requirement component 200 generates heat, the heat generated by the inner heat dissipation requirement component 200 is transferred to the inner heat dissipation sleeve 110, and then transferred to each outer heat dissipation plate 1201 through the heat conductive component 130, and then transferred to the outer sleeve body 300, and then discharged, thereby improving the heat dissipation effect. In addition, after the heat generated by the inner heat dissipation requirement component 200 is transferred to the inner heat dissipation sleeve 110, some of the heat can be discharged through the heat dissipation gap between the inner heat dissipation sleeve 110 and the outer heat dissipation plate 1201, further improving the heat dissipation effect.

[0072] It should be noted that in some cases, if the outer shell 300 generates heat, the heat generated by the outer shell 300 will be transferred to the outer heat dissipation plates 1201. This part of the heat can be discharged to a certain extent through the heat dissipation gap between the inner heat dissipation sleeve 110 and the outer heat dissipation plates 1201, thereby improving the heat dissipation effect.

[0073] It should also be noted that in the heat dissipation mechanism 100 of the present invention, each outer heat dissipation plate 1201 can move along the radial direction of the inner heat dissipation sleeve 110 under the action of the elastic member 140. Therefore, the distance between the outer heat dissipation plate 1201 and the inner heat dissipation sleeve 110 can be adjusted according to the inner diameter of the outer sleeve 300, so that the heat dissipation mechanism 100 is suitable for outer sleeves 300 with different inner diameters. In addition, under the action of the elastic member 140, the inner heat dissipation sleeve 110 and the outer heat dissipation plate 1201 can be closely fitted with the inner heat dissipation demand part 200 and the outer sleeve 300, respectively, which can increase the contact area between the inner heat dissipation sleeve 110 and the inner heat dissipation demand part 200 and the contact area between the outer heat dissipation plate 1201 and the outer sleeve 300, thereby ensuring the heat dissipation effect.

[0074] Combination Figure 2 and Figure 3 In some embodiments, at least a portion of the outer heat sinks 1201 have inner side walls provided with positioning holes 121, the total number of the positioning holes 121 is the same as the total number of the heat conductive members 130, a plurality of heat conductive members 130 and a plurality of positioning holes 121 correspond one to one, the heat conductive members 130 are connected to the inner heat sink 110 and are passed through the corresponding positioning holes 121; wherein, the heat conductive members 130 are also used to guide the outer heat sinks 1201 having the corresponding positioning holes 121 to move radially along the inner heat sink 110.

[0075] It should be noted that the heat conducting member 130 not only connects the inner heat dissipation sleeve 110 with the outer heat dissipation plate 1201 , but also guides the outer heat dissipation plate 1201 , thereby preventing the movement direction of the outer heat dissipation plate 1201 from deviating.

[0076] Specifically, the heat conductive member 130 has a columnar guide portion, each heat conductive member 130 is connected to the inner heat dissipation sleeve 110, and the axis of the guide portion of each heat conductive member 130 intersects and is perpendicular to the axis of the inner heat dissipation sleeve 110, and the positioning hole 121 corresponding to the heat conductive member 130 is coaxially arranged with the guide portion of the heat conductive member 130, and the guide portion of the heat conductive member 130 is used to be inserted into the corresponding positioning hole 121, so that the heat conductive member 130 can guide the outer heat dissipation plate 1201 and can guide the outer heat dissipation plate 1201 to move radially along the inner heat dissipation sleeve 110.

[0077] Specifically in this embodiment, the inner walls of all the outer heat dissipation plates 1201 are provided with positioning holes 121, and each positioning hole 121 is used for a heat conductive member 130 to pass through. In this way, all the outer heat dissipation plates 1201 can not only transfer heat with the inner heat dissipation sleeve 110 under the action of the heat conductive member 130, but also all the outer heat dissipation plates 1201 can accurately move along the radial direction of the inner heat dissipation sleeve 110 under the guidance of the corresponding heat conductive member 130.

[0078] Furthermore, the outer wall of the inner heat dissipation sleeve 110 is provided with a plurality of mounting holes 111, the total number of the mounting holes 111 is the same as the total number of the positioning holes 121, the plurality of heat conductive parts 130, the plurality of positioning holes 121 and the plurality of mounting holes 111 correspond one to one, and in the corresponding heat conductive parts 130, the positioning holes 121 and the mounting holes 111, the heat conductive parts 130 are passed through the mounting holes 111 and the positioning holes 121.

[0079] It can be understood that the mounting hole 111 is used for the heat conducting member 130 to pass through, thereby achieving the positioning of the heat conducting member 130 .

[0080] Specifically, the heat conductor 130 can be first inserted into the mounting hole 111 to connect the heat conductor 130 to the inner heat dissipation sleeve 110, and then the outer heat dissipation plate 1201 can be operated so that the heat conductor 130 is inserted into the positioning hole 121 of the outer heat dissipation plate 1201, thereby realizing the positioning of the outer heat dissipation plate 1201.

[0081] Among them, the mounting hole 111 is a threaded hole, which can be a through hole or a blind hole, and it passes through the outer wall of the inner heat dissipation sleeve 110; the heat conductive member 130 has a threaded section, and the threaded section of the heat conductive member 130 is inserted into the mounting hole 111, thereby realizing the connection between the heat conductive member 130 and the inner heat dissipation sleeve 110; and the positioning hole 121 is an ordinary hole, which can be a through hole or a blind hole, and it passes through the inner wall of the outer heat dissipation plate 1201; the heat conductive member 130 is inserted into the positioning hole 121, and the outer heat dissipation plate 1201 can move relative to the inner heat dissipation sleeve 110 along the radial direction of the inner heat dissipation sleeve 110.

[0082] Combination Figure 2 and Figure 4Furthermore, a first assembly hole 122 is provided on the inner wall of each outer heat dissipation plate 1201, and a plurality of second assembly holes 112 are provided on the outer wall of the inner heat dissipation sleeve 110. The total number of the first assembly holes 122, the total number of the second assembly holes 112 and the total number of the elastic members 140 are the same. The plurality of elastic members 140, the plurality of first assembly holes 122 and the plurality of second assembly holes 112 correspond one to one. In the corresponding first assembly holes 122, the second assembly holes 112 and the elastic members 140, the two ends of the elastic member 140 are respectively passed through the first assembly holes 122 and the second assembly holes 112.

[0083] It can be understood that the first assembly hole 122 and the second assembly hole 112 are used to position the elastic member 140 to reduce the risk of the elastic member 140 falling off.

[0084] Combination Figure 2 and Figure 5 In some embodiments, the heat dissipation mechanism 100 further includes a plurality of pre-tightening members 150, each outer heat dissipation plate 1201 is connected to a pre-tightening member 150, and each pre-tightening member 150 is also connected to the inner heat dissipation sleeve 110; wherein the pre-tightening member 150 is used to limit the maximum radial distance between the outer heat dissipation plate 1201 connected thereto and the inner heat dissipation sleeve 110; in the radial direction of the inner heat dissipation sleeve 110, the pre-tightening member 150 is operable to move toward the inner heat dissipation sleeve 110 to drive the outer heat dissipation plate 1201 connected thereto to move toward the inner heat dissipation sleeve 110; in the radial direction of the inner heat dissipation sleeve 110, the pre-tightening member 150 is operable to move away from the inner heat dissipation sleeve 110, so that the outer heat dissipation plate 1201 connected thereto moves away from the inner heat dissipation sleeve 110 under the drive of the elastic member 140.

[0085] It can be understood that each pre-tightening member 150 can adjust the maximum radial distance between each outer heat dissipation plate 1201 and the inner heat dissipation sleeve 110 , thereby facilitating the installation of the heat dissipation mechanism 100 .

[0086] Combination Figure 1 and Figure 2 Specifically, after the entire heat dissipation mechanism 100 is sleeved on the inner heat dissipation requirement part 200, the pre-tightening member 150 can be used to adjust the maximum radial distance between each outer heat dissipation plate 1201 and the inner heat dissipation sleeve 110, so that the outer heat dissipation sleeve 120 shrinks until the diameter of the outer heat dissipation sleeve 120 is less than or equal to the inner diameter of the outer sleeve 300, so as to facilitate the subsequent sleeve 300 on the heat dissipation mechanism 100.

[0087] Combination Figure 2 and Figure 5Furthermore, each outer heat dissipation plate 1201 is provided with a third assembly hole 123, and the inner heat dissipation sleeve 110 is provided with multiple fourth assembly holes 113. The total number of the third assembly holes 123, the total number of the fourth assembly holes 113 and the total number of the preload members 150 are the same. For the corresponding preload members 150, the third assembly holes 123 and the fourth assembly holes 113, the preload members 150 are passed through the third assembly holes 123 and the fourth assembly holes 113.

[0088] Specifically, the preload member 150 is a bolt, the third assembly hole 123 is an ordinary through hole, and the fourth assembly hole 113 is a threaded hole. The bolt is sequentially inserted into the third assembly hole 123 and the fourth assembly hole 113, and the third assembly hole 123 is provided with a step, and the threaded head of the bolt is abutted against the step. By rotating the bolt, the maximum radial distance between the outer heat dissipation plate 1201 and the inner heat dissipation sleeve 110 can be adjusted.

[0089] Combination Figure 1 , Figure 2 and Figure 3 In some embodiments, the inner heat dissipation sleeve 110 includes a plurality of inner heat dissipation plates 1101, which are arranged at intervals along a circumferential direction and surround a space for the inner heat dissipation requirement part 200 to pass through, and each inner heat dissipation plate 1101 is used to fit the outer wall of the inner heat dissipation requirement part 200.

[0090] Specifically, each inner heat dissipation plate 1101 is made of heat-conducting material, and multiple inner heat dissipation plates 1101 are arranged at intervals along a circumferential direction to form a sleeve-like structure. Specifically, each inner heat dissipation plate 1101 is an arc-shaped plate, and the axis of each inner heat dissipation plate 1101 coincides. The inner side wall of each inner heat dissipation plate 1101 is used to fit with the internal heat dissipation requirement part 200, and heat can be transferred between the inner heat dissipation plate 1101 and the internal heat dissipation requirement part 200.

[0091] It is understandable that the inner heat dissipation sleeve 110 is formed by a plurality of inner heat dissipation plates 1101 , and each inner heat dissipation plate 1101 can be expanded or contracted to change the inner diameter of the inner heat dissipation sleeve 110 , thereby being suitable for inner heat dissipation parts 200 with different outer diameters.

[0092] Combination Figure 1 and Figure 2 The heat dissipation mechanism 100 further includes a fastening unit 160 , which is used to fit and fix the plurality of inner heat dissipation plates 1101 on the outer wall of the inner heat dissipation requiring component 200 .

[0093] The fastening unit 160 may be an elastic band (such as Figure 2The fastening unit 160 may also include a plurality of screws, each inner heat dissipation plate 1101 is penetrated with a screw, and the screw may also be penetrated on the inner heat dissipation demand part 200 (such as Figure 7 shown).

[0094] Please refer to Figure 1 and Figure 2 The present invention also provides a method for installing the heat dissipation mechanism, comprising:

[0095] S100 , the inner heat dissipation sleeve 110 is sleeved on the outer side of the inner heat dissipation requirement component 200 , and the inner side wall of the inner heat dissipation sleeve 110 is fitted with the outer side wall of the inner heat dissipation requirement component 200 .

[0096] Specifically, the inner sidewalls of each inner heat dissipation plate 1101 are attached to the outside of the inner heat dissipation requiring component 200 , and the fastening unit 160 is used to fix the plurality of inner heat dissipation plates 1101 to the outer sidewalls of the inner heat dissipation requiring component 200 .

[0097] S200 , connecting a plurality of heat conducting members 130 to the inner heat dissipation jacket 110 .

[0098] Specifically, a plurality of heat conducting members 130 are inserted into the mounting holes 111 of the inner heat dissipation sleeve 110 .

[0099] S300, connecting a plurality of elastic members 140 to the inner heat dissipation sleeve 110;

[0100] Specifically, a plurality of elastic members 140 are inserted into each second assembly hole 112 of the inner heat dissipation sleeve 110;

[0101] Among them, step S200 and step S300 can be interchanged.

[0102] S400 , arranging a plurality of outer heat dissipation plates 1201 at intervals along the circumference of the inner heat dissipation sleeve 110 , making each outer heat dissipation plate 1201 abut against at least one elastic member 140 , and making at least a portion of the outer heat dissipation plates 1201 connected to at least one heat conductive member 130 .

[0103] Specifically, each outer heat dissipation plate 1201 is installed on the outer side of the inner heat dissipation sleeve 110 , and the other end of the elastic member 140 is passed through the first assembly hole 122 of the outer heat dissipation plate 1201 , and the heat conductive member 130 is passed through the positioning hole 121 of the outer heat dissipation plate 1201 .

[0104] S500 , driving all the outer heat dissipation plates 1201 to move toward the inner heat dissipation sleeve 110 by means of the pre-tightening components 150 .

[0105] Specifically, the preload member 150 can be used to adjust the maximum radial distance between each outer heat dissipation plate 1201 and the inner heat dissipation sleeve 110, so that the outer heat dissipation sleeve 120 shrinks until the diameter of the outer heat dissipation sleeve 120 is less than or equal to the inner diameter of the outer sleeve 300, so as to facilitate the subsequent connection of the outer sleeve 300 to the heat dissipation mechanism 100.

[0106] S600 , sleeve the outer sleeve 300 onto the end of the heat dissipation mechanism 100 .

[0107] Specifically, the outer sleeve 300 is only inserted into the end of the heat dissipation mechanism 100, and is not completely inserted outside the heat dissipation mechanism 100, so as to perform step S700.

[0108] S700, operate each pre-tightening member 150 to move away from the inner heat dissipation sleeve 110, so that each outer heat dissipation plate 1201 moves away from the inner heat dissipation sleeve 110 under the drive of the elastic member 140, so that the outer wall of each outer heat dissipation plate 1201 is attached and pressed against the inner wall of the outer sleeve body 300.

[0109] S800 , completely sleeve the outer shell 300 on the outside of the heat dissipation mechanism 100 .

[0110] like Figure 1 As shown, the present invention also provides a device using the above heat dissipation mechanism, the device includes the above heat dissipation mechanism 100, an inner heat dissipation component 200 and an outer sleeve 300.

[0111] Among them, the outer sleeve 300 is arranged outside the inner heat dissipation requirement component 200, and there is an assembly gap between the outer sleeve 300 and the inner heat dissipation requirement component 200; the heat dissipation mechanism 100 is arranged in the assembly gap, and the inner wall of the inner heat dissipation sleeve 110 is fitted with the outer wall of the inner heat dissipation requirement component 200, and the outer wall of each outer heat dissipation sleeve 120 is fitted with the inner wall of the outer sleeve 300.

[0112] It can be understood that when the inner heat dissipation requirement component 200 generates heat, the heat generated by the inner heat dissipation requirement component 200 is transferred to the inner heat dissipation sleeve 110, and then transferred to each outer heat dissipation plate 1201 through the heat conductive component 130, and then transferred to the outer sleeve body 300, and then discharged, thereby improving the heat dissipation effect. In addition, after the heat generated by the inner heat dissipation requirement component 200 is transferred to the inner heat dissipation sleeve 110, some of the heat can be discharged through the heat dissipation gap between the inner heat dissipation sleeve 110 and the outer heat dissipation plate 1201, further improving the heat dissipation effect.

[0113] It should be noted that in some cases, if the outer shell 300 generates heat, the heat generated by the outer shell 300 will be transferred to the outer heat dissipation plates 1201. This part of the heat can be discharged to a certain extent through the heat dissipation gap between the inner heat dissipation sleeve 110 and the outer heat dissipation plates 1201, thereby improving the heat dissipation effect.

[0114] It should also be noted that in the heat dissipation mechanism 100 of the present invention, each outer heat dissipation plate 1201 can move along the radial direction of the inner heat dissipation sleeve 110 under the action of the elastic member 140. Therefore, the distance between the outer heat dissipation plate 1201 and the inner heat dissipation sleeve 110 can be adjusted according to the inner diameter of the outer sleeve 300, so that the heat dissipation mechanism 100 is suitable for outer sleeves 300 with different inner diameters. In addition, under the action of the elastic member 140, the inner heat dissipation sleeve 110 and the outer heat dissipation plate 1201 can be closely fitted with the inner heat dissipation demand part 200 and the outer sleeve 300, respectively, which can increase the contact area between the inner heat dissipation sleeve 110 and the inner heat dissipation demand part 200 and the contact area between the outer heat dissipation plate 1201 and the outer sleeve 300, thereby ensuring the heat dissipation effect.

[0115] like Figure 6 As shown, the present invention further provides a cable system, including a first heat dissipation mechanism 100a and a second heat dissipation mechanism 100b, a cable 400 and a cable terminal.

[0116] The first heat dissipation mechanism 100a and the second heat dissipation mechanism 100b are the heat dissipation mechanisms mentioned above.

[0117] The structure of the first heat dissipation mechanism 100a can be referred to Figures 2 to 5 The structure of the second heat dissipation mechanism 100b can refer to Figures 7 to 10 .

[0118] like Figure 6 As shown, the first heat dissipation mechanism 100a is sleeved on the outside of the cable 400, and the inner heat dissipation sleeve 110 of the first heat dissipation mechanism 100a is fitted with the outer wall of the cable 400; the cable terminal includes a cone support 500 and a stress cone cover 600; the cone support 500 is sleeved on the outside of the first heat dissipation mechanism 100a, and the inner wall of the cone support 500 is fitted with the outer wall of each outer heat dissipation plate 1201 of the first heat dissipation mechanism 100a; the second heat dissipation mechanism 100b is sleeved on the outside of the cone support 500, and the inner heat dissipation sleeve 110 of the second heat dissipation mechanism 100b is fitted with the outer wall of the cone support 500; the stress cone cover 600 is sleeved on the outside of the second heat dissipation mechanism 100b, and the inner wall of the stress cone cover 600 is fitted with the outer wall of each outer heat dissipation plate 1201 of the second heat dissipation mechanism 100b.

[0119] It can be understood that when the cable 400 is heated, the heat generated by the cable 400 is transferred to the inner heat dissipation sleeve 110 of the first heat dissipation mechanism 100a, and then transferred to each outer heat dissipation plate 1201 of the first heat dissipation mechanism 100a through the heat conductive member 130 of the first heat dissipation mechanism 100a, and then transferred to the cone support 500, and then transferred to the inner heat dissipation sleeve 110 of the second heat dissipation mechanism 100b, and then transferred to each outer heat dissipation plate 1201 of the second heat dissipation mechanism 100b through the heat conductive member 130 of the second heat dissipation mechanism 100b, and then transferred to the stress cone cover 600 and discharged, and the heat dissipation effect is good. In addition, after the heat generated by the cable 400 is transferred to the inner heat dissipation sleeve 110 of the first heat dissipation mechanism 100a, part of the heat can be discharged through the heat dissipation gap between the inner heat dissipation sleeve 110 and the outer heat dissipation plate 1201 of the first heat dissipation mechanism 100a, further improving the heat dissipation effect. In addition, the heat transferred to the inner heat dissipation sleeve 110 of the second heat dissipation mechanism 100b can also be discharged through the heat dissipation gap between the inner heat dissipation sleeve 110 of the second heat dissipation mechanism 100b and the outer heat dissipation plate 1201, further improving the heat dissipation effect.
