[0043] like Figures 1-4 As shown, in one embodiment of the present invention, a wire-passing sealing plug specifically includes a sealing plug body 10, a wire-passing channel 120, and a puncture-proof wall 122. The sealing plug body 10 is made of a flexible material. In this embodiment, the sealing plug body 10 is integrally molded from rubber. In other embodiments, the specific material used for the sealing plug body 10 can be selected according to specific circumstances and is not limited here. The sealing plug body 10 is used to insert into the opening 21 to be sealed. The wire-passing channel 120 is provided on the sealing plug body 10 and is used for the wire to pass through. The puncture-proof wall 122 is provided at the entrance of the wire-passing channel 120 and is used when the wire passes through the wire-passing channel. When the cable passes through channel 120, the tip of the cable has a certain sharpness and hardness. The cable can puncture the wall 122 to be punctured, forming a hole in the wall 122 that matches the cable. After the wall 122 is punctured by the cable, the remaining part of the wall 122 located outside the hole blocks the gap between the cable passage 120 and the cable. In this embodiment, it is only described that the cable (e.g., cable, wire harness, etc.) is used to puncture the wall 122 to be punctured, and the remaining part of the wall 122 blocks the gap. It is not limited to using the cable to puncture the wall. In other embodiments, other tools (e.g., scissors, screwdrivers) can also be used to puncture the wall before the cable is passed through the cable passage 120.
[0044] In the above embodiment, the sealing plug body 10 can be manually pressed into the opening 21 in the box body without using a wrench tool, and the installation of the sealing plug body 10 is completed. After the sealing plug body 10 is inserted into the opening 21 of the box, the gap between the sealing plug body 10 and the opening 21 of the box is sealed, and the sealing plug body 10 is installed at the opening 21 of the box. The online sealing plug is simple and fast to install, and does not need to consider leaving space for wrench tightening operation inside the box. The to-be-punched wall 122 is provided in the wire passing channel 120, which can effectively seal the gap between the wire passing channel 120 and the wire body. Therefore, when the sealing plug body 10 is installed at the opening 21 of the box body, the sealing effect of the wire passing part can be achieved.
[0045] As shown in Figures 1-4 In an embodiment of the present application, the sealing plug body 10 includes a mounting sleeve 11 and a wire passing sleeve 12 arranged in the mounting sleeve 11. The end of the wire passing sleeve 12 is provided with an annular connecting wall 14 connected with the mounting sleeve 11. The outer diameter of the mounting sleeve 11 is larger than the hole diameter of the opening 21 of the box. The wire passing channel 120 and the to-be-punched wall 122 arranged in the wire passing channel 120 are both formed in the wire passing sleeve 12. The sealing plug body 10 is divided into two independent pipe sleeves, and the two pipe sleeves are connected by the annular connecting wall 14. The mounting sleeve 11 is used for installation, and the wire passing sleeve 12 is used for wire sealing. Due to the split arrangement, the two pipe sleeves can work independently without interfering with each other.
[0046] As shown in Figures 1-4 In an embodiment of the present application, the wire passing channel 120 is tapered, and the radial cross-sectional area of the wire passing channel 120 gradually decreases from the wire entry end of the wire passing channel 120 to the wire exit end of the wire passing channel 120. When the wire body passes through the wire passing channel 120, the tightness of the wire body wrapped by the wire passing sleeve 12 gradually increases, which can further improve the sealing effect between the wire passing channel 120 and the wire body.
[0047] As shown in Figures 1-4 In an embodiment of the present application, the mounting sleeve 11 and the wire passing sleeve 12 have a deformable gap 13 therebetween. The deformable gap 13 provides a deformable space for the wire passing sleeve 12 to be deformed by the wire body when the wire body passes through. The deformable gap 13 makes the wire passing channel 120 adaptable to wires of different diameters. When the wire body passes through, the deformable gap 13 of the wire passing sleeve 12 is deformed by extrusion, so as to adapt to the diameters of different wire bodies and ensure that the wire body can pass through smoothly. The elasticity of the wire passing sleeve 12 enables it to closely fit the surface of the wire body, thereby forming a good seal.
[0048] As shown in Figures 1-4As shown, in one embodiment of the present invention, there are two sealing rings 121, both of which are formed within the wire guide sleeve 12. The two sealing rings 121 are arranged sequentially at intervals along the channel direction of the wire guide channel 120. The inner diameter of each sealing ring 121 is smaller than the outer diameter of the wire passing through the wire guide channel 120. The inner diameter of the two sealing rings 121 is designed to be smaller than the outer diameter of the wire passing through the wire guide channel 120 to ensure that the wire can be tightly wrapped by the sealing rings 121, thereby achieving a good sealing effect. In this embodiment, two sealing rings 121 are provided in the wire guide channel 120. However, in other embodiments, only one sealing ring 121 is provided in the wire guide channel 120, which can also meet the sealing requirements. The specific arrangement can be selected according to the specific situation and is not limited here.
[0049] like Figures 1-5 As shown, in one embodiment of the present invention, a first limiting boss 110 is provided radially at one end of the outer peripheral surface of the mounting sleeve 11. The first limiting boss 110 is used to abut against the outer wall 22 of the box when the mounting sleeve 11 is inserted into the box opening 21. The first limiting boss 110 covers the box opening 21 in the orthogonal projection area of the outer wall 22 of the box. After the mounting sleeve 11 is inserted into the box opening 21, the first limiting boss 110 is used to limit the insertion depth of the mounting sleeve 11 in the box opening 21, preventing the sealing plug body 10 from being dragged into the box by the wire when the wire passes through the wire channel 120, and also sealing the gap between the sealing plug body 10 and the box opening 21.
[0050] like Figures 1-5 As shown, in one embodiment of the present invention, a second limiting boss 111 is provided radially at one end of the outer peripheral surface of the mounting sleeve 11. The second limiting boss 111 is used to abut against the inner wall 23 of the box when the mounting sleeve 11 is installed in the box opening 21. The second limiting boss 111 covers the box opening 21 in the orthogonal projection area of the inner wall 23 of the box. When the second limiting boss 111 is set independently, it can play a unidirectional limiting role on the inner side of the box and can also seal the gap between the sealing plug body 10 and the box opening 21. If a first limiting boss 110 and a second limiting boss 111 are provided at both ends of the outer peripheral surface of the mounting sleeve 11, the mounting sleeve 11 is bidirectionally limited on both the inner and outer sides of the box, and the mounting sleeve 11 can be firmly installed at the box opening 21, which can also seal the gap between the sealing plug body 10 and the box opening 21.
[0051] like Figures 1-4As shown in the embodiment of the present application, the first limiting boss 110 is in the shape of a disc, and the second limiting boss 111 is in the shape of an oval disc, and the length and the short axis of the oval disc are both smaller than the radius of the disc. By manually pushing the second limiting boss 111, the resistance at the opening 21 of the box is small due to the design of the oval disc. Therefore, the second limiting boss 111 is easily deformed at the opening 21 of the box and is smoothly inserted into the box. The box wall 20 is tightly clamped between the first limiting boss 110 and the second limiting boss 111. With this structure, the wire sealing plug is easily installed into the box, and the sealing plug and the box are tightly matched and not easily separated.
