[0023] The present application provides a sealing plug structure and a connector, which are described in detail below. It should be noted that the order of description of the following embodiments does not limit the preferred order of the embodiments of the present application. In addition, in the following embodiments, the description of each embodiment has its own focus. For parts not described in detail in one embodiment, please refer to the relevant description of other embodiments.
[0024] The sealing plug structure provided in the present application is used for sealing a hole structure, and the sealing plug structure includes a sealing plug and a sealing ring, and the sealing plug includes a sealing body, a cap and a stopper, and the sealing body is respectively connected to the cap and the stopper at both ends in its extension direction, and the sealing ring is sleeved on the sealing body and limited on the sealing body along the extension direction by the stopper and the cap, and the sealing ring has an outer surface configured to sealingly engage with the hole structure, and an inner surface sealingly engaged with the sealing body.
[0025] Among them, the side of the sealing body connected to the stopper is used to be inserted into the hole structure that needs to be sealed, and the side of the sealing body provided with the cap is covered at the port of the hole structure to achieve the blocking of the hole structure and prevent moisture, dust or other foreign matter from the external environment from entering the hole structure. At the same time, since the sealing body is respectively connected to the cap and the stopper at both ends of its extension direction, the sealing ring is sleeved on the sealing body and is limited to the sealing body along the extension direction by the stopper and the cap, thereby preventing the sealing ring from slipping or falling off the sealing body. In addition, since the sealing ring has an outer surface configured to sealingly engage the inner wall of the hole structure and the inner surface of the sealing body, it can ensure that the sealing plug structure has a good sealing effect and waterproof effect, which is conducive to improving the sealing performance of the sealing plug structure.
[0026] Figure 1 This is a structural diagram of the sealing plug structure in the embodiment of the present application. Figure 2 Schematic diagram of the sealing plug in the sealing plug structure in the embodiment of the present application. Figure 1 and Figure 2 The sealing plug structure provided in the present application is used for sealing a hole structure, and the sealing plug structure includes a sealing plug 1 and a sealing ring 2. The sealing plug 1 includes a sealing body 11, a cap 12 and a stopper 13. The sealing body 11 is respectively connected to the cap 12 and the stopper 13 at both ends in its extension direction. The sealing ring 2 is sleeved on the sealing body 11 and is limited on the sealing body 11 along the extension direction by the stopper 13 and the cap 12. The sealing ring 2 has an outer surface configured to sealingly engage with the hole structure, and an inner surface sealingly engaged with the sealing body 11.
[0027] In this technical solution, the side of the sealing body 11 connected to the stopper 13 is used to be inserted into the hole structure that needs to be sealed, and the side of the sealing body 11 provided with the cap 12 is covered at the port of the hole structure to achieve the blocking of the hole structure and prevent moisture, dust or other foreign matter from the external environment from entering the hole structure. At the same time, since the sealing body 11 is respectively connected to the cap 12 and the stopper 13 at both ends of its extension direction, the sealing ring 2 is sleeved on the sealing body 11 and is limited to the sealing body 11 along the extension direction by the stopper 13 and the cap 12, thereby preventing the sealing ring 2 from slipping or falling off the sealing body 11. In addition, since the sealing ring 2 has an outer surface that is configured to sealingly engage the hole wall of the hole structure and an inner surface that sealingly engages the sealing body 11, it can ensure that the sealing plug structure has a good sealing effect and waterproof effect, which is conducive to improving the sealing performance of the sealing plug structure.
[0028] For example, the sealing body 11 is a hollow cylindrical structure that, in some embodiments, can be used to accommodate elongated components, such as wires, cables, or elongated cylindrical structures, that are installed within the aperture structure. It will be appreciated that the extending direction of the sealing body 11 is the axial direction of the cylindrical sealing body 11.
[0029] Please continue to refer to Figure 2 The stopper 13 is a stop ring, which is sleeved on the outer periphery of the sealing body 11 to limit the sealing ring 2 to the left side of the extending direction of the sealing body 11. Or, as Figure 3 As shown, the stopper 13 is at least two protrusions 131 protruding from the outer periphery of the sealing body 11. The at least two protrusions 131 are arranged at equal angles around the central axis of the sealing body 11 and extend radially away from the central axis of the sealing body 11.
[0030] Specifically, the outer diameter of the stop ring gradually decreases from the cap 12 to the stop ring. Therefore, when installing the sealing ring 2, the sealing ring 2 can be first placed on the end with the smaller diameter of the stop ring, which plays a certain guiding role in the installation of the sealing ring 2 and facilitates the installation of the sealing ring 2. In addition, the outer wall of the stop ring is provided with smooth chamfers at both ends in the axial direction to protect the sealing ring 2 and prevent damage to the sealing ring 2 when it is installed from the position of the stop ring to the sealing body 11.
[0031] Furthermore, in some embodiments, the end surface of the stop ring facing away from the cap 12 is flush with the end surface of the sealing body 11 facing away from the cap 12, to avoid making the sealing body 11 too long, which would require additional manufacturing materials and would be detrimental to reducing its manufacturing cost. Furthermore, the flush end surfaces allow the end surface of the stop ring facing away from the cap 12 to be coplanar with the end surface of the sealing body 11 facing away from the cap 12, thereby providing more uniform pressure distribution, making the sealing body 11 more stable during pressure or temperature changes, and helping to prevent deformation of the sealing body 11. In some embodiments, the above-mentioned stop ring can also enhance the structural strength of the sealing body 11.
[0032] Please continue to refer to Figure 2 The cap 12 includes a cap body 121, a boss 122 protruding from the outer periphery of the cap body 121, and a positioning portion 123 provided on the outer periphery of the cap body 121. The positioning portion 123 is located on the side of the boss 122 facing the sealing body 11. The boss 122 is used to limit the depth of the sealing plug 1 inserted into the hole structure. During specific installation, the end face of the boss 122 facing the stopper 13 abuts against the end face of the structural member having the hole structure. At the same time, the positioning portion 123 is used to adapt to the adapter on the hole structure to limit the relative rotation between the two, so as to prevent the loosening caused by the rotation of the sealing plug 1, and further ensure the sealing performance and connection stability of the sealing plug structure.
[0033] It should be noted that, for the embodiment including "the stop member 13 is a stop ring, and the stop ring is sleeved on the outer periphery of the sealing body 11", and "the cover cap 12 includes a cap body 121 and a boss 122 protruding from the outer periphery of the cap body 121", the above-mentioned stop ring has a first limiting surface 132 facing the cap body 121, and the above-mentioned cap body 121 has a second limiting surface 1211 facing the stop ring. The sealing ring 2 is sleeved on the sealing body 11, and is limited between the first limiting surface 132 and the second limiting surface 1211 along the extension direction of the sealing body 11.
[0034] The sealing ring 2 has a first sealing end face and a second sealing end face arranged opposite to each other along its axial direction, and the distance between the first sealing end face and the second sealing end face is equal to or less than the distance between the first limiting surface 132 and the second limiting surface 1211. If the distance between the first sealing end face and the second sealing end face is equal to the distance between the first limiting surface 132 and the second limiting surface 1211, the two end faces of the sealing ring 2 in the axial direction respectively abut against the first limiting surface 132 and the second limiting surface 1211. If the distance between the first sealing end face and the second sealing end face is less than the distance between the first limiting surface 132 and the second limiting surface 1211, the two end faces of the sealing ring 2 in the axial direction may contact one of the first limiting surface 132 and the second limiting surface 1211, or may not contact either the first limiting surface 132 or the second limiting surface 1211.
[0035] In some embodiments, the sealing ring 2 has a first sealing end face and a second sealing end face disposed axially opposite each other, and a protrusion 21 is provided on the first sealing end face and / or the second sealing end face. For example, the protrusion 21 is a spherical bump structure. Thus, during the manufacturing process, if the sealing ring 2 falls into a gap in a machine tool or work surface, only the spherical top of the protrusion 21 will contact the gap wall, rather than the entire surface of the first and second sealing end faces, thereby facilitating removal of the sealing ring 2.
[0036] Please refer to Figure 4 The positioning portion 123 includes a plurality of positioning posts, all of which are disposed on the outer periphery of the cap body 121. Each of the positioning posts extends in the same direction as the sealing body 11. The size of the positioning post near the stopper 13 is smaller than the size of the positioning post facing away from the stopper 13. In other words, the size of the positioning post gradually decreases from the left side to the right side in the figure. This facilitates inserting the positioning post into the corresponding adapter portion during assembly of the sealing plug structure. The adapter portion is an adapter groove that matches the shape of the positioning post. There are at least two of these positioning posts, which serve as guides during installation of the sealing plug structure.
[0037] Alternatively, in some other embodiments not shown in the drawings of the present application, the positioning portion 123 includes a plurality of positioning grooves, the extension direction of each of the positioning grooves is the same as the extension direction of the sealing body 11, and the size of the positioning groove close to the stop member 13 is larger than the size of the positioning groove facing away from the stop member 13, so as to have the same function as the positioning column.
[0038] In order to further ensure the connection reliability and stability of the sealing plug structure, at least two lock buckles 1212 are connected to the outer periphery of the cap body 121, and each of the lock buckles 1212 has a coupling portion and a locking portion. The coupling portion is connected between the locking portion and the outer periphery of the cap body 121, and the locking portion extends toward the sealing body 11 along the extension direction of the positioning column. During specific installation, the locking portion is used to be coupled with the coupling portion on the protruding portion of the connector housing to achieve coupling and locking fixation between the two.
[0039] In some embodiments, as Figure 5 As shown, the end surface of the cap body 121 facing away from the sealing body 11 is provided with a groove 1213 that is recessed toward the sealing body 11. The notch of the groove 1213 is located within the end surface of the cap body 121 facing away from the sealing body 11, and the bottom of the groove 1213 is connected to the sealing body 11. As a result, the end surface of the cap body 121 facing away from the sealing body 11 is no longer a complete horizontal plane. The provision of the groove 1213 can effectively prevent high-pressure water flushing environments, thereby isolating the sealing ring 2 from the external environment of the connector housing and protecting the sealing ring 2. The sealing plug structure with the above structure can be used in more harsh environments, such as high-pressure water spraying environments.
[0040] Among them, the stop member 13 is a stop ring, which is sleeved on the outer periphery of the sealing body 11, and the cap body 121, the sealing body 11 and the stop ring are an integrated structure and are coaxially arranged. The outer diameter of the cap body 121 is larger than the outer diameter of the sealing body 11, and the outer diameter of the stop ring is larger than the outer diameter of the sealing body 11, so as to realize the limitation of the sealing ring 2 installed on the sealing body 11 in its axial direction, and the structure is simple and easy to implement.
[0041] In some embodiments of the present application, a connector is provided that includes a connector housing and a sealing plug structure as described in any of the above technical solutions. The connector housing includes a shell and a protrusion protruding from the outer periphery of the shell. The shell has a receiving cavity formed therein, and the protrusion has a hole structure disposed therein that communicates with the receiving cavity. The receiving cavity is used to accommodate a terminal assembly. The sealing plug structure is disposed in the hole structure.
[0042] It can be understood that the side of the sealing body 11 connected to the stopper 13 is used to be inserted into the hole structure, and the side of the sealing body 11 provided with the cap 12 is covered at the port of the hole structure to achieve the blocking of the hole structure, and prevent moisture, dust or other foreign matter from the external environment from entering the receiving cavity through the hole structure, so as to avoid electrical failure of the terminal assembly installed in the receiving cavity. At the same time, since the sealing body 11 is respectively connected to the cap 12 and the stopper 13 at both ends of its extension direction, the sealing ring 2 is sleeved on the sealing body 11 and is limited to the sealing body 11 along the extension direction by the stopper 13 and the cap 12, thereby preventing the sealing ring 2 from slipping or falling off from the sealing body 11. In addition, since the sealing ring 2 has an outer surface configured to sealingly engage the inner wall of the hole structure and the inner surface of the sealing body 11, it can ensure that the sealing plug structure has good sealing and waterproof effects, which is conducive to improving the sealing performance of the sealing plug structure.
[0043] Based on the above embodiment, the cap 12 includes a cap body 121 and a positioning portion 123 provided on the outer periphery of the cap body 121. An adaptor is provided on the hole wall of the hole structure. After the sealing plug 1 is connected to the hole structure, the portion of the cap body 121 provided with the positioning portion 123 is inserted into the hole structure. The positioning portion 123 is adapted to the adaptor to limit the rotation between the cap body 121 and the hole structure, and to limit the insertion depth of the cap body 121 relative to the hole structure. The outer diameter of the cap body is adapted to the inner diameter of the hole structure.
[0044] For example, the cap 12 includes a cap body 121 and a boss 122 protruding from the outer periphery of the cap body 121. The boss 122 divides the cap body 121 into a first part and a second part along the extension direction of the sealing body 11. The first part is closer to the sealing body 11 relative to the second part. The cap body 121 is provided with a positioning portion 123 on the outer periphery of the first part. The hole wall of the hole structure is provided with an adapter. After the sealing plug 1 is connected to the hole structure, the first part extends into the hole structure. The positioning portion 123 is adapted to the adapter to limit the rotational movement between the first part of the cap body 121 and the hole structure. The above-mentioned positioning portion 123 is adapted to the adapter to limit the relative rotation between the cap 12 and the protrusion to prevent the sealing plug 1 from loosening due to rotation, further ensuring the sealing performance and connection stability of the sealing plug structure.
[0045] One of the positioning portion 123 and the adapting portion is a slot structure, while the other is a columnar structure. Furthermore, the shapes of the two are compatible to ensure that they can be installed and connected together. It should be noted that the slot structure does not radially penetrate the component in which it is located.
[0046] In other embodiments, the cap 12 includes a cap body 121, and at least two locking buckles 1212 are connected to the outer periphery of the cap body 121. A clamping portion is provided on the outer periphery of the protrusion, and the locking buckles 1212 are clamped and connected to the clamping portion. For example, the locking buckles 1212 are provided with a clamping hole, and the clamping portion is a clamping protrusion. After the sealing plug 1 is connected to the hole structure, the clamping protrusion is clamped into the clamping hole. Alternatively, the clamping claws of the locking buckles 1212 have a clamping protrusion as the clamping portion, and the clamping claws are clamped with the clamping protrusions.
[0047] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.
[0048] The above is only a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any person skilled in the art can easily think of changes or replacements within the technical scope disclosed in the present application, which should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
