A first seal 250 is provided on the second box body 130, and the first seal 250 is configured to cover the end of the first fastener 230 away from the first terminal 210 and the end of the second fastener 240 away from the second terminal 220.

[0112] Since one end of the first connection harness 150 is connected to the first terminal 210, and one end of the second connection harness 160 is connected to the second terminal 220, the first fastener 230 provided on the first wiring block 200 presses the first terminal 210, and the second fastener 240 presses the second terminal 220. In other words, the first fastener 230 presses the first connection harness 150, and the second fastener 240 presses the second connection harness 160, so that the first connection harness 150 and the second connection harness 160 are fixed to the first terminal 210 and the second terminal 220, respectively. It can ensure that the first connecting wire harness 150 and the second connecting wire harness 160 are stably fixed inside the second box body 130, reducing the probability of short circuit, leakage or power outage caused by loosening or falling off of the first connecting wire harness 150 and the second connecting wire harness 160. In addition, through the fixing effect of the first fastener 230 and the second fastener 240, the position of the first connecting wire harness 150 and the second connecting wire harness 160 in the second box body 130 is stabilized, reducing the risk of displacement or damage of the first connecting wire harness 150 and the second connecting wire harness 160 due to external factors such as vibration and impact, helping to extend the service life of the first connecting wire harness 150 and the second connecting wire harness 160, and is beneficial to maintaining the stability of the power system.

[0113] A first seal 250 is also provided on the second box body 130. The first seal 250 can cover the end of the first fastener 230 away from the first terminal 210 and the end of the second fastener 240 away from the second terminal 220. That is to say, the first seal 250 can wrap the first fastener 230 and the second fastener 240 inside the first terminal 210 and the second terminal 220, thereby reducing the probability of the first connecting harness 150 and the first terminal 210 and the second connecting harness 160 and the second terminal 220 being exposed to the external air, thereby reducing the probability of power failure and leakage at the first terminal block 200.

[0114] Exemplarily, the first fastener 230 and the second fastener 240 can be set as bolts, and the first connection harness 150 and the second connection harness 160 are fastened to the first terminal 210 and the second terminal 220 respectively by bolt connection. The bolt connection is a detachable connection method. When the first terminal block 200 needs to be repaired, replaced or adjusted, it can be easily separated by removing the bolts without destroying the first fastener 230 and the second fastener 240 itself. Moreover, the bolt itself is made of high-strength materials, such as carbon steel, stainless steel or alloy steel, and can withstand large tension and shear forces. In addition, by selecting a suitable bolt diameter, length and thread type, its bearing capacity and durability can be further enhanced to ensure the long-term stability of the connection. Bolt connection has high precision because the tightness and stability of the connection can be ensured by controlling the tightening torque and preload of the bolt. This precision helps to reduce looseness and vibration and improve the operating efficiency and reliability of the equipment. Bolt connection usually does not require complex installation tools or equipment, and only basic tools such as wrenches and screwdrivers are needed to complete the installation. At the same time, due to the detachability of the bolts, the maintenance and care of the first wiring block 200 becomes easier and more convenient.

[0115] A first groove 260 and a second groove 270 are also provided on the first wiring block 200. The first groove 260 surrounds the end of the first fastener 230 away from the first terminal 210, and the second groove 270 surrounds the end of the second fastener 240 away from the second terminal 220. At least part of the first seal 250 is fitted in the first groove 260 and the second groove 270.

[0116] The first sealing member 250 may include a docking rubber block 2501 and a sealing frame 2502. The docking rubber block 2501 may be made of an insulating hard rubber material. The sealing frame 2502 is arranged on a side of the docking rubber block 2501 close to the first wiring block 200. The first wiring block 200 is provided with a first groove 260 and a second groove 270. The sealing frame 2502 cooperates with the first groove 260 and the second groove 270 respectively. The docking rubber block 2501 is docked with the first wiring block 200, which can reduce the probability of the first connection harness 150 and the second connection harness 160 being exposed to the outside of the air at the first wiring block 200, and reduce the probability of power failure and leakage at the first wiring block 200.

[0117] Please refer to Figures 1 to 8 The leakage protection device also includes a first guide member 280 arranged in the second accommodating space 131, and the first guide member 280 is provided with a first guide groove that cooperates with a portion of the first connecting wire harness 150. The leakage protection device also includes a second guide member 300 arranged in the second accommodating space 131, and the second guide member 300 is provided with a second guide groove that cooperates with a portion of the second connecting wire harness 160.

[0118] The first guide 280 and the second guide 300 are arranged in the second box body 130, the first guide 280 is arranged with a first guide groove, and the second guide 300 is arranged with a second guide groove. Part of the first connecting wire harness 150 cooperates with the first guide groove, and part of the second connecting wire harness 160 cooperates with the second guide groove, so that the first connecting wire harness 150 and the second connecting wire harness 160 can be more stably fixed inside the second box body 130, reducing the probability of the first connecting wire harness 150 and the second connecting wire harness 160 falling off, and reducing the probability of power failure and leakage at the first wiring block 200. Moreover, fixing the first connecting wire harness 150 and the second connecting wire harness 160 on the first guide 280 and the second guide 300 can make the positions of the first connecting wire harness 150 and the second connecting wire harness 160 inside the second box body 130 more orderly, reducing the probability of the first connecting wire harness 150 and the second connecting wire harness 160 appearing in disorder inside the second box body 130.

[0119] Please refer to Figures 1 to 8 A second sealing member 320 is also provided on the second box body 130, and the second sealing member 320 cooperates with the first guide member 280 and the second guide member 300 to seal part of the first connecting harness 150 in the first guide groove and part of the second connecting harness 160 in the second guide groove.

[0120] In the vertical direction, the second seal 320 is disposed on both sides of the first seal 250, and the second seal 320 is respectively clamped on the first guide 280 and the second guide 300. It can be understood that the second seal 320 is respectively clamped on the first guide groove of the first guide 280 and the second guide groove of the second guide 300. Since the first connection harness 150 and the second connection harness 160 are partially matched with the first guide groove and the second guide groove, the second seal 320 can seal the first connection harness 150 and the second connection harness 160, further reducing the probability of power failure and leakage at the first junction block 200, and improving the stability of the power system operation.

[0121] In some embodiments, the second seal 320 can be configured as a mating film that cooperates with the first guide 280 and the second guide 300 to seal portions of the first connection harness 150 and the second connection harness 160 on the first guide 280 and the second guide 300 .

[0122] Please refer to Figures 1 to 8 In this embodiment, the second box body 130 includes a box body 134 and a sealing plate 133 . The sealing plate 133 is detachably disposed on the box body 134 . A second sealing block 330 and a third sealing block 340 are disposed on the inner side of the sealing plate 133 .

[0123] The second box body 130 is also provided with a sealing plate 133, which is detachably provided on the box body 134. When it is necessary to replace or repair the internal components of the second box body 130, the sealing plate 133 can be removed, and then the internal components of the second box body 130 can be replaced or repaired. Exemplarily, a fixing screw 460 can also be provided on the side of the sealing plate 133 facing the second box body 130, and corresponding to the fixing screw 460, the second box body 130 can also be provided with a screw hole 470, and the fixing screw 460 cooperates with the screw hole 470, so that the sealing plate 133 can be detachably provided on the box body 134. The inner side surface of the sealing plate 133 (the side facing the box body 134) is provided with a second sealing block 330 and a third sealing block 340. The second sealing block 330 and the third sealing block 340 are buckled on the edge of the edge sealing groove 440. That is to say, the second sealing block 330 and the third sealing block 340 can further prevent external air from entering the interior of the second box body 130, thereby improving the vacuum degree of the second accommodating space, and thereby reducing the probability of power failure or leakage at the first wiring block 200.

[0124] Please refer to Figures 1 to 8 In this embodiment, a support column 350 is further provided on the inner side of the sealing plate 133 , and a mounting hole for accommodating the moisture absorbent member 360 is provided in the support column 350 .

[0125] The inner side of the sealing plate 133 is also provided with a support column 350. Along the length direction of the support column 350, the cross-sectional shape of the support column 350 can be set to be circular, rectangular or other polygonal. The embodiment of the present application does not impose any specific restrictions on the shape of the cross-sectional shape of the support column 350. The moisture absorbent 360 is snap-fitted to the support column 350. The moisture absorbent sheet absorbs moisture from the second accommodation space, reduces the water molecules inside the second accommodation space, reduces the probability of power failure or leakage at the first wiring block 200, and improves the stability and reliability of the power system operation.

[0126] Please refer to Figures 1 to 8 In this embodiment, the leakage protection device also includes a third seal 390, which is arranged between the inner wall of the second opening 132 and the first connecting harness 150, and the leakage protection device also includes a fourth seal 400, which is arranged between the inner wall of the third opening 170 and the second connecting harness 160.

[0127] The third seal 390 is arranged between the inner wall of the second opening 132 and the first connecting harness 150, and the fourth seal 400 is arranged between the inner wall of the third opening 170 and the second connecting harness 160, which can effectively seal the interior of the second box body 130, reduce the probability of power outage or leakage at the first wiring block 200, and improve the stability and reliability of the power system operation.

[0128] Please refer to Figures 1 to 8 There are multiple first connection harnesses 150 and multiple second connection harnesses 160 , and the other end of each first connection harness 150 is electrically connected to one end of the corresponding second connection harness 160 .

[0129] There are multiple first connection harnesses 150 and second connection harnesses 160, which can realize the metering or distribution of electric energy to different circuits or equipment, and ensure the normal operation of the power system. The other end of each first connection harness 150 is electrically connected to one end of the corresponding second connection harness 160, that is, the first connection harness 150 and the second connection harness 160 are electrically connected through the first wiring block 200, so that the current can flow from the second connection harness 160 to the first connection harness 150. Since the first wiring block 200 is arranged inside the second accommodation space, the second accommodation space is vacuumed, which can reduce the probability of power failure and leakage at the contact end of the first connection harness 150 and the second connection harness 160, and improve the stability and reliability of the operation of the power system. Exemplarily, the third seal 390 and the fourth seal 400 can be set as sealant. When the sealant is filled to the specified position, it will form a soft rubber state after curing, and will not affect the first connection harness 150 and the second connection harness 160. For example, the first connection harness 150 may enter the first connection terminal 210 through the first connection hole 480 , and the second connection harness 160 may enter the second connection terminal 220 through the second connection hole 490 , thereby electrically connecting the first connection harness 150 and the second connection harness 160 .

[0130] In some embodiments, an opening is provided at the top of the first box body 110, the first box body is connected to the external environment, a sealing rubber sleeve 310 is provided at the opening, and the vacuum pump performs vacuum processing on the protective device from the exhaust port 180. The vacuum degree of the second storage space can be higher than the vacuum degree of the first storage space, and there is less gas inside the second storage space and the negative pressure is greater.
