[0041] In this embodiment, the wires are extended and connected to the inside of the main body 1 through the sealing component 4, and the sealing cover 2 is placed on the top of the main body 1 and wrapped around the outside of the top of the main body 1. At the same time, the sealing cover 2 drives the connecting plate 24 to move to the outside of the main body 1. When it moves to the preset position, the connecting plate 24 is snapped to the main body 1, so that the sealing cover 2 is fixed on the main body 1, making the installation of the sealing cover 2 and the main body 1 more convenient. At the same time, the snap-fit ​​connection between the connecting plate 24 and the main body 1 causes the sealing cover 2 to press the sealing gasket 5, thereby sealing the sealing cover 2 and the main body 1, effectively preventing moisture intrusion and ensuring the safety and stability of the internal circuit. At the same time, when the main body 1 is installed by passing the bolt through the mounting component 3, the mounting component 3 further fixes the main body 1 and the sealing cover 2 by the bolt, improving the installation stability of the sealing cover 2 and the tightness of the connection between the sealing cover 2 and the main body 1, and further improving the sealing effect between the main body 1 and the sealing cover 2.

[0042] Example 2

[0043] like Figure 2 As shown, the waterproof junction box housing proposed in this utility model differs from the first embodiment in that the sealing cover 2 includes a cover body 21 and a limiting ring 22.

[0044] The cover 21 is fitted onto the top of the main body 1;

[0045] The limiting ring 22 is located on the inner side of the cover 21 and near the center, with the bottom end of the limiting ring 22 extending to the inner side of the main body 1.

[0046] In an optional embodiment, an extension shell 7 is provided on the inner top of the main body 1, and a cover 21 is wrapped around the outer top of the extension shell 7. A sealing gasket 5 is located between the cover 21 and the limiting ring 22 and is attached to the upper end face of the extension shell 7. It is used to limit the position of the sealing gasket 5 by the cooperation of the limiting ring 22 and the cover 21 during use, so as to prevent the connection between the sealing gasket 5 and the extension shell 7 from being misaligned.

[0047] In an optional embodiment, the bottom end of the sealing gasket 5 extends from the outer side of the limiting ring 22 toward the inner side of the extension shell 7. The sealing gasket 5 is fitted and connected to the inner side of the extension shell 7 and the outer side of the limiting ring 22. This is used to fit and connect the sealing gasket 5 to the top and inner side of the extension shell 7 during use, thereby increasing the sealing area of ​​the sealing gasket 5 and improving the sealing effect.

[0048] In an optional embodiment, a slot 6 is provided on the outer side of the extension shell 7, and a block 23 is provided on the side of the connecting plate 24. When the connecting plate 24 and the extension shell 7 are installed together, the block 23 is accommodated in the slot 6. The shapes of the slot 6 and the block 23 are only schematic. They are used to fix the connecting plate 24 to the top of the extension shell 7 by the cooperation of the slot 6 and the block 23, making the installation of the cover 21 more convenient and increasing the pressure of the edge of the cover 21 on the sealing gasket 5, thereby further improving the sealing performance of the connection between the cover 21 and the extension shell 7.

[0049] In this embodiment, the sealing gasket 5 is installed in the cover 21 by the limiting ring 22, and the cover 21 is placed on the top of the extension shell 7 and wrapped around the outside of the extension shell 7. At the same time, the cover 21 drives the connecting plate 24 to move towards the top of the main body 1, so that the connecting plate 24 drives the locking block 23 to engage with the inside of the locking groove 6. The engagement of the locking groove 6 and the locking block 23 fixes the connecting plate 24, thereby fixing the cover 21 to the top of the extension shell 7 and pressing the cover 21 against the sealing gasket 5, so that the sealing gasket 5 seals between the cover 21 and the extension shell 7. At the same time, since there are multiple connecting plates 24, the connecting plates 24 evenly press the edge of the cover 21 onto the extension shell 7, enhancing the stability and sealing of the overall structure and ensuring the waterproof effect.

[0050] Example 3

[0051] like Figure 3 As shown, the waterproof junction box housing proposed in this utility model differs from the first embodiment in that the mounting component 3 includes a first extension plate 31, a second extension plate 32, a connecting block 34, and a connecting pipe 35.

[0052] The first extension plate 31 is located at the top outer side of the cover 21 and has connecting holes at the corners;

[0053] The second extension plate 32 is located at the bottom outer side of the main body 1 and its outer dimensions are the same as those of the first extension plate 31.

[0054] There are multiple connecting blocks 34, all of which are located at the bottom end of the first extension plate 31 and have countersunk holes 33 in the middle that connect to the first extension plate 31. These holes are used to place the ends of the bolts during use and prevent the ends of the bolts from protruding from the top of the first extension plate 31.

[0055] The connecting pipe 35 is located at the top of the second extension plate 32 and at the bottom of the connecting block 34. The connecting pipe 35 and the connecting block 34 are arranged in a one-to-one correspondence.

[0056] In this embodiment, by providing a first extension plate 31 and a second extension plate 32 on the outer side of the main body 1 and the sealing cover 2, the main body 1 is installed on the outer side, reducing the number of openings on the inner side of the main body 1 and improving the waterproof effect of the main body 1. The first extension plate 31 also causes the cover 21 to move upward, allowing the cover 21 to slide out from the inner side of the slot 6 via the connecting plate 24, making the disassembly of the cover 21 convenient. At the same time, by providing a connecting block 34 and a connecting pipe 35 between the first extension plate 31 and the second extension plate 32, the connection between the first extension plate 31 and the second extension plate 32 is supported, improving the installation stability of the first extension plate 31 and preventing the bolt from causing the first extension plate 31 to bend downward.

[0057] Example 4

[0058] like Figure 4 As shown, the waterproof junction box housing proposed in this utility model differs from the first embodiment in that the sealing component 4 includes a sleeve 41, a sealing sleeve 42, and a connecting ring 44.

[0061] There are two connecting rings 44, which are respectively disposed on the outer side of one end of the sealing sleeve 42 and are fitted and connected to the end face of the sleeve 41.

[0062] In an optional embodiment, the sealing sleeve 42 has a through hole in the middle, and one end of the through hole is a tapered hole. The size of the tapered hole gradually decreases from the outside of the main body 1 to the inside of the main body 1 along the length direction of the sealing sleeve 42. This is used to improve the sealing performance of the wire by wrapping one end of the sealing sleeve 42 around the outside of the wire through the tapered hole when the wire passes through the through hole and is inserted into the inside of the main body 1.

[0063] In an optional embodiment, the inner side of the through hole of the sealing sleeve 42 is provided with a plurality of protruding rings 43. The plurality of protruding rings 43 are arranged at equal intervals inside the through hole of the sealing sleeve 42, so that they can contact the wire through the protruding rings 43 during use, and the cooperation of the plurality of protruding rings 43 can further seal the wire inside the sealing sleeve 42, thereby improving the sealing effect.

[0064] In this embodiment, when the sealing sleeve 42 is installed on the main body 1, the sleeve 41 supports it and connects to the end of the sleeve 41 through the connecting ring 44, so that the sealing sleeve 42 is fixed in the sleeve 41 and the sealing sleeve 42 has a certain length. The inner end of the sealing sleeve 42 is tapered, so that one end of the sealing sleeve 42 wraps around the outside of the wire to seal the connection. At the same time, by setting multiple protruding rings 43 on the inner side of the sealing sleeve 42, the inner side of the multiple protruding rings 43 is in close contact with the wire, so that the wire has a long sealing length inside the sealing sleeve 42, effectively preventing moisture intrusion, ensuring that the inside of the junction box is dry, and improving the overall waterproof performance.

[0065] In this invention, the wire is extended through the through hole of the sealing sleeve 42 to the inside of the main body 1 for connection. Simultaneously, the inner wall of one end of the sealing sleeve 42 wraps around the outside of the wire to seal the connection. Multiple protruding rings 43 on the inner side of the sealing sleeve 42 are fitted over the outside of the wire and closely connected to it, further sealing the wire within the sealing sleeve 42. At the same time, the cover 21 is placed on top of the extension shell 7 and wraps around the top of the extension shell 7. The cover 21 moves the sealing gasket 5 towards the extension shell 7, and the connecting plate 24 moves towards the main body 1. The connecting plate 24 moves the locking block 23 to engage with the inside of the slot 6, while the connecting plate 24 and the cover 21 simultaneously press and fix the sealing gasket 5 to the extension shell. At the top of 7, the main body 1 is fixedly connected to the sealing cover 2, and the connection position is sealed. The first extension plate 31 and the second extension plate 32 cover the outer side of the body 21 and the main body 1 respectively. At the same time, the first extension plate 31 and the second extension plate 32 are supported by the connecting block 34 and the connecting pipe 35. When the bolt passes through the first extension plate 31, the second extension plate 32, the countersunk hole 33, the connecting block 34 and the connecting pipe 35 to fix the main body 1, the shape of the countersunk hole 33 matches the bolt, so that the sealing cover 2 is fixed to the main body 1 at the same time, which improves the installation stability of the sealing cover 2, effectively prevents water intrusion, ensures that the inside of the junction box is dry, and improves the overall waterproof performance.

[0066] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto.
