[0080] In an embodiment of the application, as shown in Figures 3 to 6As shown, the target piece 200 surrounds the sealed cavity 210, and is provided with the mounting hole 220 which communicates with the sealed cavity 210. When the wire passing device 100 provided with the wire piece 300 is inserted into the mounting hole 220, one end of the wire piece 300 is located in the sealed cavity 210, and the other end is located outside the sealed cavity 210.

[0081] It should be noted that, in order to realize the wire piece 300 provided in the wire passing device 100, the wire piece 300 and the wire passing device 100 can be integrally formed, or the wire piece 300 and the wire passing device 100 are separately manufactured, and then the wire piece 300 is provided in the wire passing hole 110 of the wire passing device 100. In addition, the wire passing hole 110 of the wire passing device 100 can be reserved at least one, such as one, two, three or more, wherein the specific number of the wire passing hole 110 of the wire passing device 100 can be determined according to actual needs, which is not particularly limited herein.

[0082] In the embodiment of the utility model, as shown in Figure 1 , Figure 2 and Figure 7 , the wire passing device 100 comprises the first sealing part 1 and the second sealing part 2 which are connected, and when the wire passing device 100 is inserted into the mounting hole 220, the first sealing part 1 is at least partially inserted into the mounting hole 220, wherein the first sealing part 1 can be used to seal the gap between the hole wall of the mounting hole 220 and the outer wall of the wire passing device 100 in the mounting hole 220. Understandably, the first sealing part 1 can be directly in the mounting hole 220, and / or can indirectly seal the gap between the mounting hole 220 and the wire passing device 100 in the mounting hole 220 by plugging the mounting hole 220, which can be determined according to actual needs.

[0083] As shown in Figure 2 , the second sealing part 2 surrounds the wire passing groove 21, wherein the wire passing groove 21 is at least used for the wire piece 300 to pass through, and is used for sealing the periphery of the wire piece 300 which passes through. Understandably, by sealing the wire passing groove 21 of the second sealing part 2 provided with the wire piece 300, the periphery of the wire piece 300 can be sealed, and the gap between the wire piece 300 and the wire passing device 100 can be sealed.

[0084] And / or, after the second sealing part 2 is folded, the second sealing part 2 is sleeved on the target piece 200 to seal the gap between the hole wall of the mounting hole 220 and the outer wall of the wire passer 100 in the mounting hole 220. Understandably, by folding the second sealing part 2 to sleeve the second sealing part 2 on the target piece 200, on the one hand, the sealing length of the gap between the hole wall of the mounting hole 220 and the outer wall of the wire passer 100 in the mounting hole 220 in the extension direction of the first sealing part 1 can be extended, which is beneficial to provide better sealing performance; on the other hand, in the case of extending the sealing length of the first sealing part 1, the thickness of the target piece 200 corresponding to the mounting position is not increased, which is beneficial to simplify the overall structure; and on the other hand, the extension direction of the gap between the hole wall of the mounting hole 220 and the outer wall of the wire passer 100 in the mounting hole 220 can be changed, and the mounting hole 220 can be blocked, which further provides better sealing effect.

[0085] Exemplarily, after the wire passer 100 is mounted in the mounting hole 220, in the case that the second sealing part 2 is not folded, the sealing glue solution can be injected into the wire passing groove 21 in which the wire piece 300 is arranged, and after the glue solution is solidified, the gap between the wire piece 300 and the wire passer 100 can be sealed.

[0086] Alternatively, in the case that the second sealing part 2 is not folded, the sealing glue solution is injected into part of the wire passing groove 21 in which the wire piece 300 is arranged, and after the glue solution is solidified, the gap between the wire piece 300 and the wire passer 100 can be sealed, and then the second sealing part 2 which is not injected with the sealing glue solution is folded to block the mounting hole 220 from the outside to further seal the gap between the hole wall of the mounting hole 220 and the outer wall of the wire passer 100 in the mounting hole 220.

[0087] Alternatively, after the wire passer 100 is mounted in the mounting hole 220, the second sealing part 2 is directly folded to sleeve on the target piece 200 to block the mounting hole 220 from the outside to seal the gap between the hole wall of the mounting hole 220 and the outer wall of the wire passer 100 in the mounting hole 220.

[0088] It should be noted that the injection of the glue or the sealing glue solution described herein can be performed by a machine without manual dispensing. In addition, in actual application, the second sealing part 2 can be located outside the sealing cavity 210 or inside the sealing cavity 210, which can be determined according to actual conditions and is not particularly limited herein.

[0089] In summary, compared with the prior art, the wire passer 100 has at least the following beneficial effects:

[0090] The overline device 100 seals the gap between the hole wall of the mounting hole 220 of the target piece 200 and the outer wall of the overline device 100 in the mounting hole 220 through the physical structure of the first sealing part 1, and seals the periphery of the wire piece 300 through industrialized glue injection and the like operation on the overline groove 21 of the second sealing part 2, so as to seal the gap between the wire piece 300 and the overline device 100; and / or the second sealing part 2 is folded to be sleeved on the target piece 200, so as to extend the sealing length of the gap between the hole wall of the mounting hole 220 and the outer wall of the overline device 100 in the extension direction of the first sealing part 1, and make the extension direction of the gap between the hole wall of the mounting hole 220 and the outer wall of the overline device 100 in the mounting hole 220 turn, so that the sealing performance of the overline device 100 and the mounting hole 200 can be better; and since the sealing length of the first sealing part 1 is extended without increasing the thickness of the corresponding mounting position of the target piece 200, the overall structure is simplified. In addition, the gap between the hole wall of the mounting hole 220 and the outer wall of the overline device 100 in the mounting hole 220 can also be sealed by the physical structure of the folded second sealing part 2, so that at least one layer of sealing is implemented on the sealing cavity 210 of the target piece 200 through various sealing modes, so as to improve the sealing performance of the sealing cavity 210, the reliability is high, the expected waterproof level is reached, and the industrialization is realized without relying on manual glue injection, so as to improve the production efficiency of the product.

[0091] In order for those skilled in the art to better understand the technical scheme of the present application, the following will combine the drawings of the present application with the specific embodiments of the present application to clearly and completely describe the technical scheme of the present application. Figures 1 to 11 The technical scheme of the present application is clearly and completely described.

[0092] In some embodiments of the present application, in order to realize the sealing of the gap between the hole wall of the mounting hole 220 and the outer wall of the overline device 100 in the mounting hole 220 through the physical structure of the first sealing part 1, the first sealing part 1 has at least the following two specific embodiments, which are as follows:

[0093] In the first specific embodiment (not shown in the figure), the first sealing part (not shown in the figure) includes a support section and a sealing ring, wherein the support section is provided with a first through hole for the wire piece to pass through, and the support section is inserted into the mounting hole. The sealing ring is sleeved on the support section and tightly matched with the mounting hole. Illustratively, the wire piece is previously passed through the first through hole of the support section sleeved with the sealing ring, and then the support section sleeved with the sealing ring is inserted into the mounting hole, wherein the sealing ring can be used to seal the gap between the support section and the mounting hole, so as to realize the sealing of the gap between the hole wall of the mounting hole and the outer wall of the overline device in the mounting hole, so as to effectively reduce the water vapor entering the gap between the mounting hole and the overline device.

[0094] It should be noted that the support section can be sleeved with multiple sealing rings. Generally, the more the number of sealing rings, the higher the waterproof level. Therefore, in actual application, the number of sealing rings can be adjusted according to the waterproof level requirement.

[0095] It should also be noted that, in the case where the first sealing part includes a support section and a sealing ring, the second sealing part can also connect the support section outside the sealing cavity, so as to seal the gap between the hole wall of the mounting hole and the outer wall of the wire passing device in the mounting hole outside the sealing cavity by folding the second sealing part, so as to strengthen the sealing of the connection between the wire passing device and the target piece. And / or, glue is injected into the wire passing groove of the second sealing part outside the sealing cavity, so as to seal the connection between the wire piece and the wire passing device.

[0096] Alternatively, in the second specific embodiment, as shown in Figure 1 、 Figure 2 and Figure 7 , the first sealing part 1 includes a support section 11, a sealing ring 12 and a cover 13. The support section 11 is provided with a first through hole 111 along its axial direction for the wire piece 300 to pass through, and the support section 11 is inserted into the mounting hole 220. The sealing ring 12 is sleeved on the support section 11 and tightly fits the mounting hole 220. The cover 13 is connected to the side of the support section 11 away from the sealing cavity 210, and the cover 13 is provided with a second through hole for the wire piece 300 to pass through the first through hole 111 and is used to close the mounting hole 220 outside the sealing cavity 210. It should be noted that the diameter of the mounting hole 220 < the diameter of the sealing ring 12 ≤ the diameter of the cover 13.

[0097] Exemplarily, the wire piece 300 is sequentially passed through the second through hole and the first through hole 111 in advance, so as to pass through the first sealing part 1 with the sealing ring 12 sleeved on the support section 11, and then the first sealing part 1 with the sealing ring 12 sleeved is inserted into the mounting hole 220 of the target piece 200. When the support section 11 is inserted into the mounting hole 220, the sealing ring 12 tightly fits the mounting hole 220, so as to seal the gap between the mounting hole 220 and the wire passing device 100 from the inside of the mounting hole 220 by the sealing ring 12, and the cover 13 abuts against the target piece 200 outside the mounting hole 220, so as to seal the gap between the mounting hole 220 and the wire passing device 100 from the outside of the sealing cavity 210 by the cover 13, so as to achieve double sealing of the mounting hole 220 from the periphery of the wire passing device 100, which is beneficial to improve the sealing performance and achieve a higher waterproof level.

[0098] In some examples, as shown in Figure 1 、 Figure 2 、 Figure 4 and Figure 9As shown, to realize the sealing of the mounting hole 220 from the periphery of the wire pass-through device 100 by the cover 13, a first step 132 is formed between the cover 13 and the support section 11, wherein the first step 132 abuts against the target piece 200 at the entrance of the mounting hole 220 to jointly form a first sealing surface 133 for sealing the mounting hole 220. Understandably, when the support section 11 is inserted into the mounting hole 220, the cover 13 can completely block the mounting hole 220 outside the mounting hole 220, and the sealing gap between the wire pass-through device 100 and the mounting hole 220 is realized by the first sealing surface 133.

[0099] And / or, in some examples, to simplify the overall structure of the wire pass-through device 100, the cover 13 is integrally formed with the support section 11. For example, the cover 13 can be formed by a protruding edge of the support section 11 in the radial direction. Of course, the cover 13 can also be formed by other suitable existing or newly created ways, which are not particularly limited here.

[0100] And / or, in some examples, to facilitate adjustment of the sealing performance of the wire pass-through device 100 to meet the different waterproof level requirements of users, the sealing ring 12 is provided with multiple ones, wherein the multiple sealing rings 12 are arranged along the axial gap of the support section 11. It should be noted that generally, the waterproof level is higher as the number of sealing rings 12 increases, and the number of sealing rings 12 can be adjusted according to the actual waterproof level requirements of users.

[0101] In some embodiments of the utility model, the second sealing part 2 has a first state or a second state, and the state in which the second sealing part 2 is not folded and is directly used is the first state.
