In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0023] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0024] like Figure 1 As shown, an embodiment of the present invention relates to a cable terminal with a heat dissipation structure, which includes a terminal body 100 and a heat dissipation mechanism 200. The heat dissipation mechanism 200 is used to improve the heat dissipation effect of the terminal body 100 and reduce the risk of aging or deformation of the related cable 10 and insulation material due to the terminal body 100 being in a high temperature environment for a long time.

[0025] The terminal body 100 includes a stress cone 110 , a cone support assembly 120 and a cone cover assembly 130 .

[0026] The stress cone 110 is provided for the cable 10 to pass through. Specifically, the stress cone 110 is provided with a wire passage, and the cable 10 is passed through the wire passage and has an interference fit with the stress cone 110. The stress cone 110 is used to disperse the electric field strength at the end of the cable 10, relieve electric field concentration, and eliminate local stress spikes.

[0027] One end of the conical support assembly 120 supports the stress cone 110. The conical support assembly 120 is configured to be mounted outside the cable 10, with a first chamber 101 formed between the conical support assembly 120 and the cable 10. Specifically, the conical support assembly 120 supports the stress cone 110 to reduce the risk of relative sliding between the stress cone 110 and the cable 10. Furthermore, the conical support assembly 120 is mounted outside the cable 10, with the conical support assembly 120 spaced apart from the cable 10, forming the first chamber 101 between the conical support assembly 120 and the cable 10.

[0028] Combine Figure 1 and Figure 2 Furthermore, the cone support assembly 120 includes a cone support 122 and a cone support support 121. The cone support 122 is sleeved outside the stress cone 110 and supports the stress cone 110. One end of the cone support support 121 is connected to the cone support 122 and supports the cone support 122. The cone support support 121 extends from the cone support 122 back to the stress cone 110. The cone support support 121 is sleeved outside the cable 10 at intervals, and the first chamber 101 is formed between the cone support support 121 and the cable 10.

[0029] Furthermore, the cone support assembly 120 further includes an elastic member 123 disposed between the cone support member 121 and the cone support 122. The elastic member 123 is used to provide support force to the cone support 122 so that the cone support 122 is supported against the stress cone 110. The elastic member 123 may be a spring.

[0030] Combine Figure 1 and Figure 3 It should be noted that the end of the first chamber 101 away from the stress cone 110 is sealed by the first sealing structure 160. In other words, the end of the first chamber 101 away from the stress cone 110 is in a sealed state isolated from the outside world. It should be noted that the end of the first chamber 101 away from the stress cone 110 is sealed by the first sealing structure 160. This can mean that the first sealing structure 160 directly seals the end of the first chamber 101 away from the stress cone 110, preventing the end of the first chamber 101 away from the stress cone 110 from communicating with the outside world. It can also mean that the end of the first chamber 101 away from the stress cone 110 is still connected to other chambers, but this chamber is sealed by the first sealing structure 160, resulting in the end of the first chamber 101 away from the stress cone 110 being isolated from the outside world.

[0031] like Figure 1 As shown, one end of the cone cover assembly 130 is sleeved over the stress cone 110 and sealably engages with the stress cone 110. The cone cover assembly 130 is also sleeved over the cone support assembly 120, with the second chamber 102 formed between the cone support assembly 120. Specifically, one end of the cone cover assembly 130 is sleeved over the stress cone 110 and abuts against the stress cone 110, thereby forming a seal between the cone cover assembly 130 and the stress cone 110. Furthermore, the cone cover assembly 130 extends away from the stress cone 110 and sleeved over the cone support assembly 120 at intervals, so that the cone cover assembly 130 and the cone support assembly 120 support each other to form the second chamber 102. It will be understood that because one end of the cone cover assembly 130 is sleeved over the stress cone 110 and sealably engages with the stress cone 110, the second chamber 102 is sealed at the end adjacent to the stress cone 110.

[0032] Specifically, the cone cover assembly 130 includes a cone cover 131 and a cone cover support 132. The cone cover 131 is sleeved on the outside of the stress cone 110 and sealed with the stress cone 110. The cone cover support 132 supports the cone cover 131 to reduce the risk of relative sliding between the cone cover 131 and the stress cone 110. The cone cover support 132 extends from the cone cover 131 back to the stress cone 110 and is sleeved on the outside of the cone support 121 at intervals. At least part of the second chamber 102 is formed between the cone cover support 132 and the cone support 121.

[0033] Combine Figure 1 and Figure 2Furthermore, the second chamber 102 is connected to the first chamber 101 . Specifically, one end of the second chamber 102 close to the stress cone 110 is connected to one end of the first chamber 101 close to the stress cone 110 .

[0034] like Figure 2 As shown, specifically, one end of the cone support member 121 close to the stress cone 110 extends to the side of the stress cone 110, and the one end of the cone support member 121 close to the stress cone 110 is spaced from the stress cone 110 to form a gap, and the second chamber 102 is connected to the first chamber 101 through the gap.

[0035] Combine Figure 1 and Figure 3 It should be noted that the end of the second chamber 102 away from the stress cone 110 is sealed by the second sealing structure 170; in other words, the end of the second chamber 102 away from the stress cone 110 is in a sealed state isolated from the outside world.

[0036] It should be further explained that the first chamber 101 and the second chamber 102 are isolated from the outside world, so that the outside air, water vapor, etc. can be prevented from entering the first chamber 101 and the second chamber 102 to affect the cable 10, stress cone 110 and other components.

[0037] Combine Figure 1 and Figure 3 The heat dissipation mechanism 200 is arranged outside the terminal body 100. The heat dissipation mechanism 200 includes a circulating air pipe 210 and an air pump 220 arranged on the circulating air pipe 210. One end of the circulating air pipe 210 is connected to the first chamber 101, and the other end is connected to the second chamber 102.

[0038] It is understood that the heat dissipation mechanism 200 is disposed outside the terminal body 100 and does not occupy additional internal space of the terminal body 100. Specifically, the circulating air pipe 210 is located outside the terminal body 100, and the air pump 220 is also located outside the terminal body 100. The circulating air pipe 210 is used to connect the first chamber 101 and the second chamber 102. In this way, the first chamber 101, the second chamber 102, and the circulating air pipe 210 form a circulation loop. When the air pump 220 is turned on, the gas in the first chamber 101 and the second chamber 102 can circulate in the circulation loop, thereby improving the gas flowability and improving the heat dissipation performance of the cable terminal. In addition, the heat dissipation mechanism 200 is disposed outside the terminal body 100, and the gas in the circulating air pipe 210 can also better exchange heat with the outside air. The heat in the circulating air pipe 210 is more easily dissipated to the outside world, further improving the heat dissipation effect.

[0039] like Figure 3As shown, further, the terminal body 100 is provided with a first air hole communicating with the first cavity 101 and a second air hole communicating with the second cavity 102 , and both ends of the circulation air pipe 210 are respectively connected to the first air hole and the second air hole.

[0040] Specifically, the terminal body 100 also includes a tail pipe transition piece 180, which is connected to the end of the cone support assembly 120 away from the stress cone 110 and is used to be mounted outside the cable 10. A third chamber 103 connected to the first chamber 101 is formed between the tail pipe transition piece 180 and the cable 10. The first sealing structure 160 is disposed at the end of the third chamber 103 away from the first chamber 101. The tail pipe transition piece 180 is provided with a first air hole connected to the third chamber 103, and the second sealing structure 170 is provided with a second air hole connected to the second chamber 102. The first and second air holes are respectively connected at both ends of the circulating air pipe 210.

[0041] Furthermore, a first self-sealing valve 240 is provided at the outer end of the first air hole, a second self-sealing valve 250 is provided at the outer end of the second air hole, and both ends of the circulating air pipe 210 are connected to the first self-sealing valve 240 and the second self-sealing valve 250 respectively.

[0042] It can be understood that before the circulating air pipe 210 is connected, the first self-sealing valve 240 seals the first air hole and the second self-sealing valve 250 seals the second air hole. When the two ends of the circulating air pipe 210 are respectively connected to the first self-sealing valve 240 and the second self-sealing valve 250, the first self-sealing valve 240 and the second self-sealing valve 250 are in a normally open state.

[0043] Furthermore, a gas drying device 230 is provided on the circulating gas pipe 210 to dry the gas and reduce the moisture in the gas. Furthermore, the gas drying device 230 is filled with color-changing silica gel. When the color-changing silica gel completely changes color, the gas drying device 230 needs to be replaced.

[0044] It should be noted that when the gas drying device 230 is replaced, the connection structure between the circulating gas pipe 210 and the first self-sealing valve 240 can be removed. After the circulating gas pipe 210 and the first self-sealing valve 240 are disassembled, the first self-sealing valve 240 remains closed, which can prevent outside air from entering the first chamber 101 and the second chamber 102.

[0045] Combine Figure 3 and Figure 5In some embodiments, the first sealing structure 160 includes a first flange 161 connected to the end of the tail pipe transition piece 180 away from the cone support assembly 120, and a first compression-sealing rubber ring 163 supported by the first flange 161 and sealed on the cable 10, wherein the first flange 161 is also connected to a support ring 162, and the support ring 162 is supported by the first compression-sealing rubber ring 163.

[0046] Furthermore, the terminal body 100 further includes a tail pipe 190 , which is connected to the first flange 161 and sleeved outside the cable 10 .

[0047] Combine Figure 3 and Figure 4 In some embodiments, the second sealing structure 170 includes a second flange 171 connected to the end of the cone support assembly 120 away from the stress cone 110, a third flange 172 connected to the end of the cone cover assembly 130 away from the stress cone 110, and a second pressure sealing rubber ring 173 arranged between the second flange 171 and the third flange 172.

[0048] Furthermore, a fourth flange 181 is connected to one end of the tail pipe transition piece 180 close to the cone support assembly 120 . The fourth flange 181 is connected to the second flange 171 . The second air hole passes through the second flange 171 and the fourth flange 181 and communicates with the second chamber 102 .

[0049] like Figure 1 As shown, it should be noted that the cable terminal also includes a sleeve 140, which is sleeved on the outside of the cone cover assembly 130, wherein a accommodating cavity 104 for filling the insulating layer 150 is formed between the sleeve 140 and the cone cover assembly 130, and the second cavity 102 and the first cavity 101 are both separated from the accommodating cavity 104.

[0050] It can be understood that the stress cone 110 is sealed outside the cable 10 to prevent the insulating layer 150 from entering between the stress cone 110 and the cable 10. One end of the cone cover assembly 130 is sleeved outside the stress cone 110 to prevent the insulating layer 150 from entering the second chamber 102.

[0051] The present invention also provides a cable system, comprising the cable terminal with a heat dissipation structure of the above embodiment and a cable 10, wherein the cable 10 is passed through the cone support assembly 120 and the stress cone 110, and the cable 10 and the cone support assembly 120 form a first chamber 101.

[0052] In the cable system of the present invention, the heat dissipation mechanism 200 is arranged outside the terminal body 100 and does not occupy additional internal space of the terminal body 100. Specifically, the circulating air pipe 210 is located outside the terminal body 100, and the air pump 220 is also located outside the terminal body 100. Among them, the circulating air pipe 210 is used to connect the first chamber 101 and the second chamber 102. In this way, the first chamber 101, the second chamber 102 and the circulating air pipe 210 form a circulation loop. When the air pump 220 is turned on, the gas in the first chamber 101 and the second chamber 102 can circulate in the circulation loop, thereby improving the fluidity of the gas and improving the heat dissipation performance of the cable terminal. In addition, the heat dissipation mechanism 200 is arranged outside the terminal body 100, and the gas in the circulating air pipe 210 can also better exchange heat with the outside air. The heat in the circulating air pipe 210 is more easily dissipated to the outside, further improving the heat dissipation effect.
