Description

Cable guides and waterproofing equipment

[0001] This application claims priority to Chinese Patent Application No. 202423154941.9, filed on December 18, 2024, entitled "Wire Guide and Waterproof Device", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of waterproof and dustproof technology, and in particular to a wire guide and waterproof equipment. Background Technology

[0003] To ensure a certain level of waterproofing, components requiring electrical connections, such as motors and circuit boards, are typically installed within a sealed cavity. Cables are then routed through this cavity to establish electrical connections between the internal and external components.

[0050] To address the aforementioned technical problems, this application also provides a waterproof device, employing the technical solution described below:

[0051] The waterproofing equipment includes:

[0052] The mounting component surrounds a sealing cavity and has a mounting hole communicating with the sealing cavity;

[0053] The aforementioned cable guide;

[0054] When the wire guide with the wire threaded through it is inserted into the mounting hole, one end of the wire thread is located inside the sealing cavity, and the other end of the wire thread is located outside the sealing cavity.

[0055] Compared with the prior art, the cable guide and waterproof device provided in this application have the following advantages:

[0056] This cable guide seals the gap between the wall of the mounting hole of the target component and the outer wall of the cable guide inside the mounting hole through the physical structure of the first sealing part, and seals the periphery of the cable component by industrial-scale glue injection and other operations on the cable groove of the second sealing part, thereby sealing the gap between the cable component and the cable guide; and / or folds the second sealing part to fit onto the target component, thereby extending the sealing length of the gap between the wall of the mounting hole and the outer wall of the cable guide inside the mounting hole in the extending direction of the first sealing part, and causing the extending direction between the wall of the mounting hole and the outer wall of the cable guide inside the mounting hole to change, so that the sealing performance between the cable guide and the mounting hole can be better; and since the thickness of the target component at the corresponding mounting position is not increased when the sealing length of the first sealing part is extended, it is beneficial to simplify the overall structure. Furthermore, the physical structure of the folded second sealing part can also seal the gap between the hole wall of the mounting hole and the outer wall of the wire guide inside the mounting hole. This allows for at least one or two layers of sealing of the sealing cavity of the target part through various sealing methods, thereby improving the sealing performance and reliability of the sealing cavity, which is conducive to achieving the expected waterproof level. Moreover, it does not require manual glue application, which is conducive to industrialization and thus improves the production efficiency of the product. Attached Figure Description

For example, when an element is referred to as "connected to" another element, it may be directly or indirectly connected to that other element.

[0073] Furthermore, the reference to "embodiment" herein means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0074] This application provides a wire guide 100, as shown in Figures 1 and 2, which is used for installation on a target component 200. The target component 200 described herein includes, but is not limited to, mounting components for equipment such as cleaning robots and lawnmowers. It should be noted that the wire guide 100 is generally applicable to electrical equipment, waterproof equipment 1000, or dustproof equipment that only requires electrical connection, waterproofing, and / or dustproofing. This application does not specifically limit the application scenarios of the wire guide 100.

[0075] In the embodiments of this application, as shown in Figures 3 to 6, the target component 200 is surrounded by a sealing cavity 210 and has a mounting hole 220 communicating with the sealing cavity 210. When the wire guide 100 through which the wire component 300 passes is inserted into the mounting hole 220, one end of the wire component 300 is located inside the sealing cavity 210 and the other end is located outside the sealing cavity 210. For example, the wire 300 can be first passed through the wire guide 100, and then the wire guide 100 with the wire 300 can be inserted into the mounting hole 220 from the outside of the sealing cavity 210 or from the inside of the sealing cavity 210. After the wire guide 100 is encapsulated in the mounting hole 220, one end of the wire 300 in the wire guide 100 can be located inside the sealing cavity 210 and the other end can be located outside the sealing cavity 210, so that the electrical connection between the inside and outside of the sealing cavity 210 can be achieved by passing the wire 300 through the wire guide 100.

[0076] It should be noted that, to allow the wire 300 to pass through the wire guide 100, the wire 300 and the wire guide 100 can be integrally formed, or the wire 300 and the wire guide 100 can be manufactured separately, and then the wire 300 can pass through the wire guide hole 110 reserved in the wire guide 100. Furthermore, the wire guide 100 can have at least one wire guide hole 110, such as one, two, three, or more. The specific number of wire guide holes 110 in the wire guide 100 can be determined according to actual needs and is not specifically limited here.

[0077] In the embodiments of this application, as shown in Figures 1, 2, and 7, the cable guide 100 includes a first sealing portion 1 and a second sealing portion 2 connected together. When the cable guide 100 is inserted into the mounting hole 220, the first sealing portion 1 is at least partially inserted into the mounting hole 220. The first sealing portion 1 can be used to seal the gap between the wall of the mounting hole 220 and the outer wall of the cable guide 100 within the mounting hole 220. Understandably, the first sealing portion 1 can be directly inside the mounting hole 220 and / or indirectly outside the sealing cavity 210 by blocking the mounting hole 220 to achieve the gap between the mounting hole 220 and the cable guide 100 within it, depending on actual needs.

[0078] As shown in Figure 2, the second sealing part 2 is surrounded by a wire passage groove 21, wherein the wire passage groove 21 is at least used for the wire 300 to pass through and for sealing the periphery of the wire 300 through which it passes. Understandably, by sealing the wire passage groove 21 of the second sealing part 2 through which the wire 300 passes, the periphery of the wire 300 can be sealed, thereby sealing the gap between the wire 300 and the wire guide 100.

[0079] And / or, after the second sealing part 2 is folded over, it is fitted around the target part 200 outside the mounting hole 220 to seal the gap between the wall of the mounting hole 220 and the outer wall of the wire guide 100 inside the mounting hole 220. Understandably, by folding the second sealing part 2 over to fit it onto the target part 200, on the one hand, the sealing length of the gap between the wall of the mounting hole 220 and the outer wall of the wire guide 100 inside the mounting hole 220 can be extended in the extending direction of the first sealing part 1, which is beneficial for providing better sealing performance; on the other hand, while extending the sealing length of the first sealing part 1, the thickness of the target part 200 at the corresponding mounting position is not increased, which is beneficial for simplifying the overall structure; furthermore, the extending direction of the gap between the wall of the mounting hole 220 and the outer wall of the wire guide 100 inside the mounting hole 220 can be reversed, and the mounting hole 220 can be sealed, further providing a better sealing effect.

[0080] For example, after the wire guide 100 is installed in the mounting hole 220, if the second sealing part 2 is not folded, sealant can be filled into the wire groove 21 through which the wire member 300 passes. After the sealant cures, the gap between the wire member 300 and the wire guide 100 can be sealed.

[0081] Alternatively, without folding the second sealing part 2, sealant is injected into a portion of the wire guide groove 21 through which the wire member 300 passes. After the sealant cures, the gap between the wire member 300 and the wire guide 100 can be sealed. Then, the second sealing part 2 without sealant is folded over to block the mounting hole 220 from the outside, which can also seal the gap between the wall of the mounting hole 220 and the outer wall of the wire guide 100 inside the mounting hole 220.

[0082] Alternatively, after the wire guide 100 is installed in the mounting hole 220, the second sealing part 2 can be folded over and sleeved on the target part 200 to seal the mounting hole 220 from the outside, thereby sealing the gap between the hole wall of the mounting hole 220 and the outer wall of the wire guide 100 inside the mounting hole 220.

[0083] It should be noted that the adhesive injection or filling of sealant described herein can be performed directly by machine without manual dispensing. Furthermore, in practical applications, the second sealing part 2 can be located outside or inside the sealing cavity 210, depending on the specific circumstances, and is not specifically limited here.

[0084] In summary, compared with existing technologies, the wire guide 100 has at least the following beneficial effects:

[0085] The wire guide 100 seals the gap between the wall of the mounting hole 220 of the target part 200 and the outer wall of the wire guide 100 inside the mounting hole 220 through the physical structure of the first sealing part 1, and seals the periphery of the wire part 300 by industrial-scale glue injection into the wire groove 21 of the second sealing part 2, thereby sealing the gap between the wire part 300 and the wire guide 100; and / or folds the second sealing part 2 to fit onto the target part 200, thereby extending the sealing length of the gap between the wall of the mounting hole 220 and the outer wall of the wire guide 100 inside the mounting hole 220 in the extending direction of the first sealing part 1, and turning the extending direction between the wall of the mounting hole 220 and the outer wall of the wire guide 100 inside the mounting hole 220, so that the sealing performance between the wire guide 100 and the mounting hole 200 can be better; and since the thickness of the target part 200 at the corresponding installation position is not increased when the sealing length of the first sealing part 1 is extended, it is beneficial to simplify the overall structure. Furthermore, the physical structure of the folded second sealing part 2 can also seal the gap between the hole wall of the mounting hole 220 and the outer wall of the wire guide 100 inside the mounting hole 220. Thus, at least one layer of sealing is achieved for the sealing cavity 210 of the target part 200 through multiple sealing methods, thereby improving the sealing performance of the sealing cavity 210. This results in high reliability, facilitates achieving the expected waterproof rating, and eliminates the need for manual glue application, which is conducive to industrialization and improves product production efficiency.

[0086] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to Figures 1 to 11.

[0087] In some embodiments of this application, in order to seal the gap between the wall of the mounting hole 220 and the outer wall of the wire guide 100 inside 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 implementations, as follows:

[0088] In a first specific embodiment (not shown), the first sealing part (not shown) includes a support section and a sealing ring. The support section has a first through hole for the wire to pass through, and the support section is inserted into the mounting hole. The sealing ring is sleeved on the support section and tightly fitted into the mounting hole. Exemplarily, the wire passes through the first through hole of the support section with the sealing ring sleeved beforehand, and then the support section with the sealing ring sleeved is inserted into the mounting hole. The sealing ring can be used to seal the gap between the support section and the mounting hole, thereby sealing the gap between the wall of the mounting hole and the outer wall of the wire guide inside the mounting hole, effectively reducing the ingress of moisture from the gap between the mounting hole and the wire guide.

[0089] It should be noted that the support section can be fitted with multiple sealing rings. Generally, the higher the number of sealing rings, the higher the waterproof rating. Therefore, in practical applications, the number of sealing rings can be adjusted according to the waterproof rating requirements.

[0090] It should also be noted that, when the first sealing part includes a support section and a sealing ring, the second sealing part can also be connected to the support section outside the sealing cavity. This allows the second sealing part to be folded over outside the sealing cavity to seal the gap between the wall of the mounting hole and the outer wall of the cable guide inside the mounting hole, thereby strengthening the seal at the connection between the cable guide and the target component. And / or, by injecting adhesive into the cable guide groove of the second sealing part outside the sealing cavity, the connection between the cable component and the cable guide can be sealed.

[0091] Alternatively, in a second specific embodiment, as shown in Figures 1, 2, and 7, the first sealing part 1 includes a support section 11, a sealing ring 12, and a cover 13. The support section 11 has a first through hole 111 along its axial direction for the wire 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 fitted into the mounting hole 220. The cover 13 is connected to the side of the support section 11 opposite to the sealing cavity 210; the cover 13 has a second through hole for the wire 300 to pass through the first through hole 111, 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.

[0092] For example, the wire 300 passes through the second through hole and the first through hole 111 in sequence before passing through the first sealing part 1 of the support section 11, which is fitted with a sealing ring 12. Then, the first sealing part 1 with the sealing ring 12 is inserted into the mounting hole 220 of the target part 200. When the support section 11 is inserted into the mounting hole 220, the sealing ring 12 is tightly fitted with the mounting hole 220 to seal the gap between the mounting hole 220 and the wire guide 100 from the inside of the mounting hole 220. The cover 13 abuts against the target part 200 outside the mounting hole 220 to seal the gap between the mounting hole 220 and the wire guide 100 from the outside of the sealing cavity 210. This achieves a double seal on the mounting hole 220 from the periphery of the wire guide 100, which helps to improve the sealing performance and achieve a higher waterproof rating.

[0093] In some examples, as shown in Figures 1, 2, 4, and 9, a first step 132 is formed between the cover 13 and the support section 11 to achieve a seal on the mounting hole 220 from the periphery of the cable guide 100. At the entrance of the mounting hole 220, the first step 132 abuts against the target member 200 to jointly form a first sealing surface 133 that seals 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 from the outside, and the first sealing surface 133 seals the gap between the cable guide 100 and the mounting hole 220.

[0094] And / or, in some examples, to simplify the overall structure of the wire guide 100, the cover 13 is integrally formed with the support section 11. For example, the cover 13 may be formed by a radially projecting flange of the support section 11. Of course, the cover 13 may also be formed by other suitable existing or innovative methods, which are not particularly limited here.

[0095] And / or, in some examples, to facilitate adjustment of the sealing performance of the wire guide 100 to meet different waterproofing requirements of users, multiple sealing rings 12 are provided, wherein the multiple sealing rings 12 are arranged along the axial gap of the support section 11. It should be noted that, generally, the waterproofing level is higher as the number of sealing rings 12 increases, and the number of sealing rings 12 can be adjusted according to the user's actual waterproofing requirements.

[0096] In some embodiments of this application, 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 available for use is set as the first state. As shown in Figures 1 to 6, in the first state, the wire groove 21 of the second sealing part 2 is filled with cast sealant (not shown) to seal the gap between the wire component 300 and the wire groove 21, thereby achieving a seal between the wire component 300 and the wire guide 100.

[0097] Alternatively, the second state can be defined as a state in which at least part of the second sealing part 2 is folded over for use. In the second state, the target part 200 has a mounting boss 230 protruding inside or outside the sealing cavity 210 (see Figures 8 to 11), and the mounting boss 230 and the target part 200 connected thereto have a mounting hole 220. The second sealing part 2 is folded over and fitted onto the mounting boss 230 to seal the mounting hole 220 outside the mounting hole 220. Alternatively, a cast sealant (not shown) is cured on the side of the wire guide groove 21 near the first sealing part 1 to seal the gap between the wire part 300 and the wire guide hole 110 of the wire guide 100. Furthermore, the second sealing part 2, on the side away from the first sealing part 1, is folded towards the target part 200 and fitted onto the mounting boss 230. The folded second sealing part 2 then seals the mounting hole 220 outside the mounting hole 220, thereby sealing the gap between the wire guide 100 and the mounting hole 220. This achieves sealing of the mounting hole 220 from both the inner and outer layers of the wire guide 100, which helps to improve the sealing performance of the sealing cavity 210.

[0098] It should be noted that the first state and the second state of the second sealing part 2 are different usage states of the second sealing part 2, and the specific state can be selected according to actual needs.

[0099] In some embodiments of this application, a second step 22 is formed between the second sealing part 2 and the first sealing part 1, wherein, outside the mounting hole 220, the second step 22 abuts against the mounting boss 230 to jointly form a second sealing surface 23 that seals the mounting hole 220.

[0100] For example, as shown in FIG9, the second sealing part 2 is located in the sealing cavity 210. The outer diameter of the second sealing part 2 is larger than the outer diameter of the first sealing part 1, and the outer diameter of the second sealing part 2 is smaller than the outer diameter of the mounting boss 230, so as to form a second step 22 between the second sealing part 2 and the first sealing part 1. When the second sealing part 2 is folded, the second step 22 can abut against the mounting boss 230. On the one hand, the gap between the mounting hole 220 and the wire guide 100 can be sealed by the second sealing surface 23 inside the sealing cavity 210 and outside the mounting hole 220. On the other hand, it is beneficial that the folded part of the second sealing part 2 can be tightly fitted onto the mounting boss 230. The fit between the second sealing part 2 and the mounting boss 230 will not be loose due to the outer diameter of the second sealing part 2 being too large, and the fit between the second sealing part 2 and the mounting boss 230 will not be difficult to fit onto the mounting boss 230 when folding due to the outer diameter of the second sealing part 2 being too small.

[0101] In some embodiments of this application, as shown in Figures 1, 2 and 7, the wire guide 100 further includes a third sealing part 3. As shown in Figures 4 and 9, the third sealing part 3 is connected to the side of the first sealing part 1 away from the sealing cavity 210, wherein the third sealing part 3 has a third through hole 31 for the wire 300 to pass through, and is used to seal the gap between the wire 300 and the third through hole 31.

[0102] To achieve the sealing function of the third sealing part 3, in some examples, the wire guide 100 has a wire-passing hole 110 along its axial direction. As shown in Figures 2 to 6 and Figures 8 to 11, when the wire component 300 and the wire guide 100 are manufactured separately, the wire guide 100 also includes a fastener 4. The fastener 4 is used to press the third sealing part 3 from its periphery to seal the gap between the wire component 300 and the wire-passing hole 110 outside the sealing cavity 210, thereby preventing most of the liquid flow, airflow, dust, etc., from entering the sealing cavity 210. It should be noted that the fastener 4 includes, but is not limited to, cable ties.

[0103] For example, when the second sealing part 2 is connected to the end of the first sealing part 1 near the sealing cavity 210, and the first sealing part 1 also includes a cover 13, the third through hole 31 of the third sealing part 3, the second through hole of the cover 13, the first through hole 111 of the support section 11, and the wire passage groove 21 of the second sealing part 2 can together form the aforementioned wire passage hole 110. The wire 300 can sequentially pass through the third through hole 31, the second through hole, the first through hole 111, and the wire passage groove 21 to pass through the wire guide 100 with the sealing ring 12 fitted on the support section 11. Then, the support section 11 with the sealing ring 12 is inserted into the mounting hole 220 of the target part 200, so that the second sealing part 2 is located inside the sealing cavity 210, the third sealing part 3 and the cover 13 of the first sealing part 1 are located outside the mounting hole 220, and the two ends of the wire 300 are located inside and outside the sealing cavity 210, respectively. Then, fasteners 4, such as cable ties, are used to cover the third sealing part 3, and the fasteners 4 clamp the wire 300 from the outside of the third sealing part 3, thereby sealing the gap between the wire 300 and the third through hole 31 outside the mounting hole 220, so as to block most of the liquid flow, air flow, dust and other substances from entering the sealing cavity 210 from the wire hole 110, which helps to improve the sealing performance.

[0104] And / or, when the wire guide 100 with wire 300 is inserted into the mounting hole 220, a sealant for sealing the gap between the wire guide hole 110 and the wire 300 is cured inside the wire guide hole 110.

[0105] For example, the sealant inside the wire hole 110 can be formed by curing adhesive adhering to the wire 300 passing through the wire hole 110. For instance, adhesive can be first applied to the wire 300, and then the wire 300 with adhesive can be passed through the wire hole 110 of the wire guide 100. After the adhesive cures, sealant can be formed inside the wire hole 110 to achieve a seal.

[0106] And / or, the sealant in the wire passage hole 110 can be formed by curing the adhesive poured into the wire passage groove 21 of the second sealing part 2. For example, after the support section 11 of the first sealing part 1 of the wire guide 100 is inserted into the mounting hole 220, adhesive can be injected into the wire passage groove 21 of the third sealing part 3 located outside the sealing cavity 210 or outside the sealing cavity 210. The injected adhesive may also enter the first through hole 111 of the support section 11 from the wire passage groove 21. In this way, after the adhesive cures, sealant can be formed in the wire passage groove 21 and / or the first through hole 111 to seal the wire passage hole 110.

[0107] In summary, when the wire guide 100 of this paper is inserted into the mounting hole 220 at the first sealing part 1, it has at least the following sealing methods, as detailed below:

[0108] The first sealing method is to seal the gap between the mounting hole 220 and the wire guide 100 by tightly fitting the sealing ring 12 inside the mounting hole 220 with the hole wall of the mounting hole 220.

[0109] The second sealing method involves sealing the entrance of the mounting hole 220 outside the mounting hole 220 by using the cover 13 of the first sealing part 1, thereby sealing the gap between the mounting hole 220 and the wire guide 100.

[0110] The third sealing method involves sealing the mounting hole 220 by using a second sealing part 2 located outside or inside the sealing cavity 210 to block the mounting hole 220 from the outside, thereby achieving a seal between the mounting hole 220 and the wire guide 100.

[0111] The fourth sealing method involves injecting adhesive into the wire groove 21 of the second sealing part 2 located outside or inside the sealing cavity 210. After the adhesive cures, the gap between the wire component 300 and the wire hole 110 of the wire guide 100 is sealed by the sealant.

[0112] The fifth sealing method involves clamping the third sealing part 3 from the periphery of the third sealing part 3 with fasteners 4 to seal the gap between the wire part 300 and the wire hole 110 of the wire guide 100.

[0113] The sixth sealing method involves first applying adhesive to the wire 300 before it passes through the wire guide 100, then passing the wire 300 with the adhesive through the wire guide hole 110 of the wire guide 100, and sealing the wire guide hole 110 after the adhesive has cured.

[0114] It should be noted that the first sealing method is the same as that used in all examples. The second to sixth sealing methods can be used in various combinations according to actual needs, and will not be listed here.

[0115] This application embodiment also provides a wire guide 100, which is used to install on a target component 200. The target component 200 is surrounded by a sealing cavity 210 and has a mounting hole 220 communicating with the sealing cavity 210. When the wire guide 100, through which a wire component 300 passes, is inserted into the mounting hole 220, one end of the wire component 300 is located inside the sealing cavity 210 and the other end is located outside the sealing cavity 210. For example, the wire 300 can be first passed through the wire guide 100, and then the wire guide 100 with the wire 300 can be inserted into the mounting hole 220 from the outside of the sealing cavity 210 or from the inside of the sealing cavity 210. After the wire guide 100 is encapsulated in the mounting hole 220, one end of the wire 300 in the wire guide 100 can be located inside the sealing cavity 210 and the other end can be located outside the sealing cavity 210, so that the electrical connection between the inside and outside of the sealing cavity 210 can be achieved by passing the wire 300 through the wire guide 100.

[0116] In embodiments of this application, as shown in Figures 1, 2, and 7, the cable guide 100 includes a first sealing part 1, a second sealing part 2, and a third sealing part 3. The first sealing part 1 is at least partially inserted into the mounting hole 220. The first sealing part 1 can be used to seal the gap between the wall of the mounting hole 220 and the outer wall of the cable guide 100 within the mounting hole 220. Understandably, the first sealing part 1 can be directly inside the mounting hole 220, and / or indirectly outside the sealing cavity 210, by blocking the mounting hole 220 to achieve the gap between the mounting hole 220 and the cable guide 100 within it, depending on actual needs.

[0117] As shown in Figures 1, 2 and 7, the third sealing part 3 is connected to the side of the first sealing part 1 away from the sealing cavity 210. The third sealing part 3 can be used to seal the gap when the wire 300 is running on the outside of the sealing cavity 210.

[0118] In addition, the second sealing part 2 is connected to the first sealing part 1, and the second sealing part 2 has a first state or a second state. The state in which the second sealing part 2 is used directly without being folded is set as the first state; the state in which the second sealing part 2 is used after at least part of it is folded is set as the second state.

[0119] In the first state, as shown in Figures 2 and 6, the second sealing part 2 is provided with a wire passage groove 21 for the wire 300 to pass through. The wire passage groove 21 is at least used to seal the gaps when the wire 300 is running through the internally injected cured sealant.

[0120] In the second state, as shown in Figures 8 and 11, the target component 200 has a mounting boss 230 protruding inside or outside the sealing cavity 210. The mounting boss 230 and the target component 200 connected thereto have a mounting hole 220. As shown in Figure 9, the second sealing part 2 is folded over and fitted onto the mounting boss 230 to seal the mounting hole 220 from the outside, thereby sealing the gap of the first sealing part 1 in the mounting hole 220.

[0121] In summary, compared with existing technologies, the wire guide 100 has at least the following beneficial effects:

[0122] The wire guide 100 seals the gap between the wall of the mounting hole 220 of the target part 200 and the outer wall of the wire guide 100 inside the mounting hole 220 through the physical structure of the first sealing part 1. By performing industrial-scale glue injection and other operations on the wire groove 21 of the second sealing part 2, the periphery of the wire part 300 is sealed, thereby sealing the gap between the wire part 300 and the wire guide 100. And / or the second sealing part 2 is folded over to be fitted onto the target part 200, thereby extending the sealing length of the gap between the wall of the mounting hole 220 and the outer wall of the wire guide 100 inside the mounting hole 220 in the extending direction of the first sealing part 1, and causing the extending direction between the wall of the mounting hole 220 and the outer wall of the wire guide 100 inside the mounting hole 220 to be reversed, so that the sealing performance between the wire guide 100 and the mounting hole 220 can be better. Moreover, since the thickness of the target part 200 at the corresponding installation position is not increased when the sealing length of the first sealing part 1 is extended, it is beneficial to simplify the overall structure. Furthermore, the physical structure of the folded second sealing part 2 can also seal the gap between the wall of the mounting hole 220 and the outer wall of the wire guide 100 inside the mounting hole 220. And by operating the third sealing part 3 accordingly, the gap of the wire 300 when the wire is running can be sealed on the outside of the sealing cavity 210. Thus, by using multiple sealing methods, the mounting hole 220 entering the sealing cavity 210 in the target part 200 can be sealed with both inner and outer layers, thereby improving the sealing performance of the sealing cavity 210. It has high reliability, is conducive to achieving the expected waterproof level, and does not require manual glue application, which is conducive to industrialization and thus improves the production efficiency of the product.

[0123] In some embodiments of this application, as shown in Figures 1, 2, and 7, the first sealing part 1 includes a support section 11 and a sealing ring 12. As shown in Figures 4 and 9, the support section 11 is inserted into the mounting hole 220, and the support section 11 has a first through hole 111 for the wire 300 to pass through (see Figure 2). The sealing ring 12 is sleeved on the support section 11 and tightly fitted into the mounting hole 220. The second sealing part 2 and the third sealing part 3 are respectively connected to opposite ends of the support section 11. Exemplarily, when the wire guide 100 is inserted into the mounting hole 220, the second sealing part 2 is located inside the sealing cavity 210, and the third sealing part 3 is located outside the sealing cavity 210.

[0124] In some embodiments of this application, as shown in Figures 4 and 9, the first sealing part 1 further includes a cover 13, wherein the cover 13 is connected to the side of the support section 11 away from the sealing cavity 210 and is connected to the third sealing part 3.

[0125] When the cable guide 100 is inserted into the mounting hole 220, the cover 13 abuts against the target part 200 at the entrance of the mounting hole 220, and together with the target part 200, forms a first sealing surface 133 to seal the mounting hole 220. The first sealing surface 133 blocks the mounting hole 220 outside the sealing cavity 210, thereby sealing the gap between the mounting hole 220 and the cable guide 100.

[0126] And / or, in the second state, the second sealing part 2 abuts against the mounting boss 230 at the outlet of the mounting hole 220, and together with the mounting boss 230 forms a second sealing surface 23 to seal the mounting hole 220, so as to block the mounting hole 220 inside the sealing cavity 210 and outside the mounting hole 220 through the second sealing surface 23, so as to seal the gap between the mounting hole 220 and the wire guide 100.

[0127] It should be noted that the cable guide 100 described in this embodiment has a generally similar structure to the cable guide 100 described above, and details in all aspects will not be repeated here.

[0128] Based on the aforementioned cable guide 100, as shown in Figures 2 to 6 and Figures 8 to 11, this application embodiment also provides a waterproof device 1000, which includes a mounting member 200 and the aforementioned cable guide 100. The mounting member 200 surrounds a sealing cavity 210 and has a mounting hole 220 communicating with the sealing cavity 210. When the cable guide 100, through which a cable 300 is threaded, is inserted into the mounting hole 220, one end of the cable 300 is located inside the sealing cavity 210, and the other end of the cable 300 is located outside the sealing cavity 210.

[0129] It should be noted that the mounting component 200 mentioned here is the target component 200 to which the above-mentioned cable guide 100 is plugged.

[0130] In summary, compared with the prior art, the waterproofing device 1000 has at least the following beneficial effects: by using the aforementioned wire guide 100, the waterproofing device 1000 implements at least one layer of sealing on the mounting hole 220 of the mounting component 200 through multiple sealing methods, thereby significantly improving the sealing performance and sealing reliability of the sealing cavity 210, which is conducive to achieving the expected waterproofing level, and does not require manual glue application, which is conducive to industrialization, thereby improving the production efficiency of the waterproofing device 1000.

[0131] The above description is merely a preferred embodiment of this application and is not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art.
