DETAILED DESCRIPTION

[0031] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0032] In the present disclosure, unless otherwise specified, directional words such as "inside" and "outside" refer to "inside" and "outside" relative to the corresponding component's own contour. In addition, the terms "first", "second", etc. used in the present disclosure are to distinguish one element from another and do not have order and importance. In addition, in the following description, when referring to the drawings, unless otherwise explained, the same figure numbers in different drawings represent the same or similar elements. The above definitions are only used to explain and illustrate the present disclosure and should not be understood as limitations on the present disclosure.

[0033] The present disclosure provides a hole plug assembly 1, which is used to close a terminal hole 3 of a connector. Figures 1 to 5 As shown in , the hole plug assembly 1 includes: a breathable member 12, which is suitable for being arranged in the terminal hole 3 to cover the terminal hole 3; and a sealing blind plug 13, which is detachably connected to the breathable member 12 and is suitable for being pluggable and arranged in the terminal hole 3.

[0034] Through the above technical solution, when the hole plug assembly 1 provided by the present disclosure is used, on the one hand, the terminal hole 3 of the connector can be reliably sealed by the cooperation of the air-permeable member 12 and the sealing blind plug 13 to ensure that the connector meets the air-tightness detection requirements. On the other hand, the sealing blind plug 13 can be removed from the air-permeable member 12 and the terminal hole 3 while the air-permeable member 12 is set in the terminal hole 3 of the connector. In this way, when the connector is assembled, the gas can be discharged through the air-permeable member 12 to reduce the pressure inside the connector and reduce the bonding force during the assembly of the connector, thereby reducing the labor intensity of the workers. In addition, since the hole plug assembly 1 of the present disclosure is an independently set component and is not directly attached to the connector itself, it can be selected to be inserted into the terminal hole 3 of the connector or pulled out from the terminal hole 3 of the connector according to actual conditions, so it has better flexibility.

[0035] In the exemplary embodiment provided by the present disclosure, the air permeable member 12 can be arranged in the terminal hole 3 in any suitable manner, and the present disclosure does not limit this. Optionally, the hole plug assembly 1 can also include a hole plug body 11, the hole plug body 11 is provided with a through hole 111 penetrating through itself and is suitable for being sealedly arranged in the terminal hole 3, the air permeable member 12 is arranged in the hole plug body 11 and covers the through hole 111, and the sealing blind plug 13 is pluggable and arranged in the through hole 111. Through such an arrangement, the air permeable member 12 and the sealing blind plug 13 can be reliably arranged in the terminal hole 3 of the connector with the help of the hole plug assembly 1.

[0036] In the exemplary embodiment provided by the present disclosure, the hole plug body 11 has a first end and a second end that are relatively arranged, the air permeable member 12 is arranged at the first end, and the sealing blind plug 13 is arranged at the second end, so that when the hole plug assembly 1 is inserted into the terminal hole 3 of the connector as a whole, the end provided with the air permeable member 12 can be directed toward the inside of the terminal hole 3, and the end provided with the sealing blind plug 13 can be directed to the outside and partially exposed to the outside, so that whether it is a detection process that requires the sealing blind plug 13 to be inserted or an assembly process that requires the sealing blind plug 13 to be removed, the corresponding plugging and unplugging operations of the sealing blind plug 13 can be conveniently performed through the part of the sealing blind plug 13 exposed to the outside.

[0037] In the above embodiment, “one end of the sealing blind plug 13 faces the outside and is partially exposed to the outside” means that the main body of the sealing blind plug 13 is inserted into the through hole 111 of the plug body 11, while part or all of the operating part is exposed to the outside of the through hole 111.

[0038] In the exemplary embodiment provided by the present disclosure, the air-permeable member 12 can be disposed on the hole plug body 11 in any suitable manner, and the present disclosure does not limit this. Optionally, the air-permeable member 12 can be directly disposed on the hole plug body 11 by bonding or the like, or can be indirectly disposed on the hole plug body 11 by other structures or components. Figure 1 and Figure 3 As shown in the figure, a first mounting groove 14 is formed at the first end of the hole plug body 11, and the air-permeable member 12 is disposed in the first mounting groove 14 and connected to the first mounting groove 14 by bonding or the like. The first mounting groove 14 can be formed by the first end being recessed inwardly, or can be formed by any other suitable method, which is not limited by the present disclosure.

[0039] In the exemplary embodiments provided in the present disclosure, reference is made to Figure 1 As shown in the figure, in order to realize the sealed connection between the hole plug assembly 1 and the terminal hole 3 of the connector, the hole plug assembly 1 can be provided to further include a sealing member 15, the sealing member 15 is sleeved on the hole plug body 11 and is suitable for being sealedly arranged in the terminal hole 3, so that when the hole plug assembly 1 is inserted into the terminal hole 3 of the connector, due to the setting of the sealing member 15, the hole plug body 11 in the hole plug assembly 1 can be sealedly connected with the terminal hole 3 of the connector through the sealing member 15.

[0040] It should be noted that the terms "sealed connection" and "sealed arrangement" and the like in the present disclosure are used to refer to the arrangement without gap between two components. For example, "sealed connection between the hole plug assembly 1 and the terminal hole 3 of the connector" means that there is no gap between the hole plug assembly 1 and the terminal hole 3 of the connector, and "the seal 15 is sleeved on the hole plug body 11 and is suitable for sealingly setting in the terminal hole 3" means that there is no gap between the hole plug body 11 and the terminal hole 3 of the connector through the seal 15.

[0041] In the exemplary embodiment provided by the present disclosure, the seal 15 can be directly set on the hole plug body 11, or can be set on the hole plug body 11 in any other suitable manner, which can be flexibly selected according to actual conditions, and the present disclosure does not limit this. Figure 1 As shown in , the outer wall of the hole plug body 11 can be concavely formed with a second installation groove 16 along the circumferential direction, and the seal 15 is arranged in the second installation groove 16. Here, the seal 15 can be configured as any suitable seal 15 such as a sealing ring, which can be flexibly selected according to actual conditions, and the present disclosure does not limit this.

[0042] In the exemplary embodiment provided by the present disclosure, the breathable member 12 can be a waterproof breathable member, which can not only ensure the breathability of the connector during the assembly process to reduce the bonding force between the connectors and reduce the labor intensity of the workers, but also ensure the waterproof performance of the connector during subsequent use to ensure safe use. Among them, the waterproof breathable member can be constructed as a waterproof breathable membrane, a waterproof breathable valve or other waterproof breathable member. Among them, constructing the waterproof breathable member as a waterproof breathable membrane can make the structure of the hole plug assembly 1 simple, easy to implement, and low in cost. In the exemplary embodiment provided by the present disclosure, reference Figure 1 and Figure 2 As shown in the figure, the sealing blind plug 13 may include a blind plug body 131 and a sealing portion 132, and the sealing portion 132 is arranged on the outer wall of the blind plug body 131. In this way, when the sealing blind plug 13 is inserted into the through hole 111 of the plug body 11, the setting of the blind plug body 131 and the sealing portion 132 can completely seal the through hole 111 of the plug body 11, thereby avoiding the influence of the through hole 111 on the plug body 11 on the air tightness detection of the connector.

[0043] In the exemplary embodiments provided by the present disclosure, the sealing portion 132 can be constructed in any suitable manner, and the present disclosure does not limit this. For example, when the blind plug body 131 is made of a hard material (such as plastic, metal, etc.), the construction method of the sealing portion 132 can refer to the setting method of the sealing member 15 on the outer wall of the hole plug body 11 in the previous text; when the blind plug body 131 is made of a soft material (such as silicone, rubber, etc.), one implementation method of the sealing portion 132 is to refer to Figure 1As shown in , the sealing portion 132 can be made of the same soft material as the blind plug body 131. In this case, the sealing portion 132 is coated on the outer periphery of the blind plug body 131 and can be integrally formed with the blind plug body 131. When the blind plug body 131 is made of a soft material (such as silicone, rubber, etc.), another implementation method of the sealing portion 132 is to refer to Figure 2 As shown in FIG. 1 , the sealing portion 132 is configured as a sealing protrusion protruding along the circumferential direction of the outer wall of the blind plug body 131 .

[0044] Among them, when the sealing portion 132 is constructed as a sealing protrusion protruding circumferentially along the outer wall of the blind plug body 131, the sealing protrusion may include multiple sealing protrusions, and the multiple sealing protrusions are arranged axially along the blind plug body 131. In this way, by increasing the number of sealing protrusions, when the connector is tested for air tightness, these sealing protrusions arranged layer by layer along the axial direction of the blind plug body 131 can ensure layer by layer that the sealing blind plug 13 reliably seals the through hole 111 of the plug body 11, thereby further ensuring the normal detection of the air tightness of the connector.

[0045] In the exemplary embodiments provided in the present disclosure, reference is made to Figure 2 As shown in the figure, the multiple sealing protrusions may include a first sealing protrusion 132a and a second sealing protrusion 132b, and the sealing blind plug 13 has an implantation end 133, and the first sealing protrusion 132a is close to the implantation end 133. In this way, when the first sealing protrusion 132a fails during the air tightness test of the connector, the second sealing protrusion 132b arranged on the outer layer can timely and reliably seal the through hole 111 on the plug body 11 to ensure the normal progress of the air tightness test of the connector. Therefore, such a setting can further improve the reliability of the sealing blind plug 13 and reduce replacement.

[0046] In the exemplary embodiments provided in the present disclosure, reference is made to Figure 2 As shown in , the first sealing protrusion 132a and the second sealing protrusion 132b can be constructed in any suitable manner, and the present disclosure is not limited to this. Optionally, the first sealing protrusion 132a and the second sealing protrusion 132b can be constructed in the following three possible implementations:

[0047] In a first possible implementation manner, the first sealing protrusion 132a and the second sealing protrusion 132b may be configured as bowl-shaped protrusions.

[0048] In a second possible implementation manner, the first sealing protrusion 132a and the second sealing protrusion 132b may be configured as columnar protrusions.

[0049] In a third possible implementation, refer to Figure 2 As shown in FIG. , the first sealing protrusion 132 a may be configured as a columnar protrusion, and the second sealing protrusion 132 b may be configured as a bowl-shaped protrusion.

[0050] In the above three possible implementations, the columnar protrusion refers to a sealing protrusion with the same outer diameter, and the bowl-shaped protrusion refers to a sealing protrusion with one end being large and the other end being small and having an arc-shaped outer wall. Among them, since the columnar protrusion has the same outer diameter, the contact area between the columnar protrusion and the through hole 111 of the hole plug body 11 will be relatively large. Therefore, constructing the first sealing protrusion 132a or the second sealing protrusion 132b as a columnar protrusion can increase the contact area between the sealing blind plug 13 and the through hole 111 in the hole plug body 11, increase the friction between the two, and thus improve the sealing performance of the sealing protrusion. Since the bowl-shaped protrusion is large at one end and small at the other end and has an arc-shaped outer wall, when the first sealing protrusion 132a or the second sealing protrusion 132b is constructed as a bowl-shaped protrusion, the small end of the bowl-shaped protrusion can be set toward the implantation end 133 of the sealing blind plug 13. This is beneficial to the smooth insertion of the sealing blind plug 13 on the one hand, and on the other hand, the arc-shaped design of the outer wall of the bowl-shaped protrusion can also buffer the airflow generated inside the connector, thereby increasing the service life of the sealing blind plug 13.

[0051] Among them, reference Figure 2 As shown in , to ensure that the second sealing protrusion 132b can reliably seal the through hole 111 in the plug body 11 in time when the first sealing protrusion 132a fails, the outer diameter of the first sealing protrusion 132a can be set smaller than the outer diameter of the second sealing protrusion 132b.

[0052] In the exemplary embodiments provided in the present disclosure, reference is made to Figure 2 As shown in the figure, in order to facilitate the process of inserting the sealing blind plug 13 into the through hole 111 of the hole plug body 11 more smoothly, it can be provided that the sealing blind plug 13 also includes a guide portion 134, the sealing blind plug 13 has an implantation end 133, and the guide portion 134 is arranged at the implantation end 133. The guide portion 134 can be constructed in any suitable manner. Exemplarily, the guide portion 134 can be constructed as an inverted cone.

[0053] In the exemplary embodiments provided in the present disclosure, reference is made to Figure 2 As shown in , in order to facilitate the plugging and unplugging of the sealing blind plug 13 , the sealing blind plug 13 may further include a plugging and unplugging handle 135 , which is disposed at one end of the sealing blind plug 13 away from the through hole 111 .

[0054] In order to explain in detail the functions of the hole plug assembly 1 of the present disclosure, the following will be described in combination with three different states of the connector:

[0055] The first state is the airtightness test state of the connector. Figure 4As shown in , in this state, the hole plug assembly 1 of the present invention is inserted into the terminal hole 3 of the connector that is not equipped with the conductive wire 4, and at this time, the sealing blind plug 13 also needs to be inserted into the corresponding position of the through hole 111 of the hole plug body 11, and the side of the connector where the terminal of the conductive wire 4 is exposed is used to connect with the conductive tooling 5 to form a sealed space for air-tightness detection. In this way, due to the arrangement of the hole plug body 11 and the sealing blind plug 13, the terminal hole 3 in the connector that is not equipped with the conductive wire 4 can be well sealed. In this way, it can be avoided that the connector is affected by the fact that some terminal holes 3 are not equipped with the conductive wire 4 during the air-tightness detection process, so that the normal detection of the air-tightness of the connector can be ensured.

[0056] The second state is the final assembly state of the connector, refer to Figure 5 As shown in , in this state, the hole plug assembly 1 of the present invention continues to be inserted into the terminal hole 3 of the connector where the conductive wire 4 is not inserted. At the same time, the sealing blind plug 13 needs to be pulled out from the through hole 111 of the hole plug body 11, and the side of the connector where the terminal of the conductive wire 4 is exposed is used to connect with the plug end 6 to form a closed space. At this time, since the through hole 111 of the hole plug body 11 is covered with a waterproof breathable part but the sealing blind plug 13 is not inserted, the compressed gas generated in the closed space during the final assembly process can be discharged through the waterproof breathable part 12 provided on the through hole 111, thereby reducing the force applied to the connector by the workers during the final assembly of the connector, and ultimately reducing the labor intensity of the workers during the final assembly of the connector.

[0057] The third state, that is, the use state of the connector, continues to refer to Figure 5 As shown in the figure, in this state, the hole plug body 11 is always inserted in the terminal hole 3 of the connector, and the sealing blind plug 13 needs to be pulled out from the through hole 111 of the hole plug body 11. Since the waterproof breathable component is always arranged in the hole plug body 11 and can cover the through hole 111, when the connector is in use, the through hole 111 of the hole plug body 11 inserted in the terminal hole 3 of the connector is still provided with a waterproof breathable component, and the waterproof breathable component is not only waterproof but also breathable, that is, when the connector in the use state is inserted with the hole plug assembly 1, it can not only realize the waterproof function inside the connector, but also realize the convection heat exchange between the inside of the connector and the external air.

[0058] On the basis of the above technical solution, the present disclosure further provides a connector, which includes a connector body 2 and the above hole plug assembly 1, the connector body 2 is provided with a terminal hole 3, and the hole plug assembly 1 is arranged in the terminal hole 3 to close the terminal hole 3. Figure 4 and Figure 5As shown in , the connector has a detection state and an assembly state. In the detection state, the sealing blind plug 13 is inserted into and seals the terminal hole 3; in the assembly state, the sealing blind plug 13 is removed to avoid the terminal hole 3. Here, since the above process has described the relationship between the connector and the hole plug assembly 1 in detail, the present disclosure will not repeat it here to avoid repetition.

[0059] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings; however, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0060] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0061] In addition, various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
