Description

Technical Field

[0001] This application relates to the field of terminal technology, and in particular to a communication device and connection component. Background Technology

[0002] With the continuous development of outdoor communication equipment, the demand for Power over Ethernet (PoE) technology continues to grow. This technology enables the simultaneous transmission of power and network signals through a single network cable (i.e., a PoE cable), allowing the cable to not only provide power to outdoor communication equipment but also enable data communication between the outdoor communication equipment and indoor systems.

[0003] Typically, the physical connection structure and sealing reliability between the PoE cable and outdoor communication equipment are crucial for ensuring system stability. In related technologies, PoE cables are connected to outdoor communication equipment via threaded, waterproof cable connectors to guarantee the waterproof performance and mechanical stability of the connection point.

[0004] However, this installation method requires users to assemble at least four different parts, making the installation process more complex and reducing installation efficiency. Furthermore, due to the complex structural design and multiple sealing connection points, the overall waterproof performance is reduced, affecting the reliability of equipment operation. Utility Model Content

[0005] This application provides a communication device and a connection component, which can not only improve the installation efficiency of the device, but also improve the reliability of the device operation to a certain extent.

[0006] To achieve the above objectives, the embodiments of this application adopt the following technical solutions:

[0007] In a first aspect, this application provides a communication device, comprising: a device body, an elastic retainer, a seal, and a connecting housing; the device body has a port; the elastic retainer is connected to the side of the device body having the port; the seal has a through hole for a cable to pass through; the elastic retainer is sleeved on the seal, and the through hole and the elastic retainer are used for the cable to pass through and connect to the port; the connecting housing is sleeved on the elastic retainer and connected to the device body; the elastic retainer is elastically deformable and is used to abut against the surface of the seal.

[0008] When connecting the cable to the communication equipment, the user only needs to pass the cable sequentially through the connecting housing, the through hole of the seal, and the elastic retainer, and then connect it to the port on the equipment body. Next, the elastic retainer is installed onto the equipment body, and the seal is housed within the elastic retainer. Finally, the connecting housing is fixedly connected to the equipment body, completing the entire connection process. Since the connection process mainly involves three core components—the elastic retainer, the seal, and the connecting housing—the number of parts required for installation is reduced, making the installation process simpler and more efficient, thus improving the equipment's installation efficiency. Furthermore, during the connection process between the connecting housing and the equipment body, the elastic retainer undergoes elastic deformation, applying a clamping force to the seal, ensuring a tight fit against the cable's outer wall, effectively improving sealing and waterproofing performance, thereby enhancing the reliability of equipment operation.

[0009] In one possible implementation, the resilient retainer includes: a fixed portion connected to the device body on one side having a port, and multiple resilient arms extending along the fixed portion on the side opposite to the device body. The multiple resilient arms are spaced apart on the outer periphery of the seal and are capable of elastic deformation to abut against the surface of the seal.

[0010] During the connection process between the housing and the device body, multiple elastic arms undergo elastic deformation under stress, thereby applying clamping force to the seal and ensuring a tight fit against the cable's outer wall. This not only improves connection stability but also achieves excellent sealing performance, thereby enhancing the operational reliability of the communication equipment.

[0011] In one possible implementation, the resilient retainer has a receiving space comprising: a first cavity segment and a second cavity segment that are in communication; the first cavity segment is closer to the device body than the second cavity segment, and the inner diameter of the first cavity segment is smaller than the inner diameter of the second cavity segment, so as to form a first annular limiting surface between the first cavity segment and the second cavity segment. The seal is located within the second cavity segment and is in contact with the first annular limiting surface.

[0012] The first annular limiting surface provides reliable axial support for the seal. During assembly, the seal is stably confined within the second cavity segment enclosed by the elastic retainer, effectively preventing the seal from shifting during installation and thus improving installation stability.

[0013] In one possible implementation, the resilient retainer has a plurality of first engaging portions on the side facing the device body, the plurality of first engaging portions being distributed circumferentially along the resilient retainer; the device body has a plurality of second engaging portions that mate with the plurality of first engaging portions. The plurality of first engaging portions and the plurality of second engaging portions correspond one-to-one, with each first engaging portion engaging with its corresponding second engaging portion.

[0014] Through the precise matching and snap-fit ​​of the first and second snap-fit ​​parts, a reliable mechanical connection is achieved between the elastic retainer and the device body. This snap-fit ​​structure not only improves the overall mechanical strength of the communication equipment but also enhances its resistance to external vibrations or impacts. Furthermore, compared to traditional screws or other fixing methods, this snap-fit ​​structure requires no additional tools for assembly, effectively simplifying installation steps, reducing assembly complexity, and thus improving assembly efficiency and ease of operation.

[0015] In one possible implementation, one of the first and second snap-fit ​​portions is a snap-fit ​​protrusion and the other is a snap-fit ​​groove; at least a portion of the snap-fit ​​protrusion is located within the snap-fit ​​groove.

[0016] By embedding the snap-fit ​​protrusion into the snap-fit ​​groove, displacement of the elastic retainer during use can be effectively prevented, thereby improving the stability of the connection between the elastic retainer and the equipment body. Simultaneously, because the snap-fit ​​protrusion and snap-fit ​​groove have a clear mating relationship, they can guide the accurate alignment and installation of the elastic retainer, avoiding misalignment and improving assembly efficiency.

[0017] In one possible implementation, the device body has a protrusion on the side facing the connecting housing, and the connecting housing is connected to the protrusion.

[0018] During the connection process between the housing and the protrusion in the device body, multiple elastic arms in the elastic retainer undergo elastic deformation and apply clamping force to the seal, making it fit tightly against the outer wall of the cable, thereby effectively improving the sealing and waterproof performance, and thus improving the reliability of the communication equipment operation.

[0019] In one feasible approach, the connecting housing is threadedly connected to the protrusion.

[0020] The inner wall of the connecting housing has an internal thread section, and the outer wall of the protruding part has a corresponding external thread section. The two are connected by threaded engagement. This allows the position of the connecting housing relative to the main body of the equipment to be adjusted by rotating the connecting housing. In addition, the threaded connection design simplifies the installation process, allowing for quick assembly without additional tools and improving assembly efficiency.

[0021] In one possible implementation, the fixing portion includes a first sub-fixing portion and a second sub-fixing portion, the first sub-fixing portion being closer to the device body than the second sub-fixing portion. The outer diameter of the first sub-fixing portion is smaller than the outer diameter of the second sub-fixing portion, forming a second annular limiting surface between the first and second sub-fixing portions. The communication device also includes a sealing gasket located between the second annular limiting surface and the end of the protrusion facing away from the device body.

[0022] By placing a sealing gasket between the second annular limiting surface and the end of the protrusion facing away from the equipment body, after the elastic retainer and the equipment body are engaged, the sealing gasket is compressed and deformed by the combined action of the second annular limiting surface and the end of the protrusion, thereby forming a sealing barrier between the connecting housing and the equipment body. This effectively prevents external moisture, dust, and other contaminants from entering the equipment body. Furthermore, since the sealing gasket is positioned with a clearly defined support surface provided by the second annular limiting surface, potential misalignment or displacement during assembly is avoided, improving assembly accuracy.

[0023] In one possible implementation, the outer wall of the fixing part has at least one first positioning surface, and the inner wall of the protrusion has at least one second positioning surface, with the first and second positioning surfaces in contact with each other.

[0024] When the connecting housing is connected to the protrusion via threaded rotation, the first positioning surface and the second positioning surface fit tightly together. Because the positioning surfaces adopt a rectangular planar structure, when the elastic retainer tends to rotate, the two rectangular planes will directly contact each other, thus restricting its rotational freedom. In this way, the elastic retainer is reliably fixed to the device body after assembly, preventing relative rotation and thus avoiding the transmission of rotational force through the seal. This prevents torsional deformation of the seal and cable, ensuring a stable connection between the cable and the communication equipment and improving the reliability of equipment operation.

[0025] In one possible implementation, the cross-sectional shape of the through hole in the seal is circular; or, the cross-sectional shape of the through hole in the seal is rectangular.

[0026] By setting the cross-sectional shape of the through hole in the seal to be either circular or rectangular, the adaptation requirements of cables of different shapes can be met, thereby improving the compatibility of communication equipment with various cable types.

[0027] In one possible implementation, the through hole has a circular cross-sectional shape, and its diameter gradually increases along a first direction; or, the diameter of the through hole gradually decreases along the first direction. The first direction is the insertion / removal direction of the cable.

[0028] Because the diameter of the through hole gradually increases or decreases in the cable insertion / removal direction, the seal can achieve a good fit and seal regardless of the direction the cable is inserted. Therefore, there is no need to specify the installation direction of the seal during assembly, significantly improving assembly flexibility.

[0029] In one feasible approach, the seal is a resilient seal.

[0030] During the connection process between the housing and the device body, multiple elastic arms undergo elastic deformation under external force, thereby applying clamping force to the seal. Since the seal is made of elastic material, it can undergo corresponding elastic deformation after being subjected to the clamping force from the multiple elastic arms, causing its inner wall to fit tightly against the outer wall of the cable. This not only improves the stability of the connection but also achieves excellent sealing performance, thereby enhancing the reliability of the communication equipment.

[0031] Secondly, this application provides a connection assembly, including: an elastic retainer, a seal, and a connecting housing; the seal has a through hole for a cable to pass through; the elastic retainer is sleeved on the surface of the seal; the connecting housing is sleeved on the elastic retainer; the elastic retainer is elastically deformable for abutting against the surface of the seal.

[0032] When connecting the cable to the communication equipment, the user only needs to pass the cable sequentially through the connecting housing, the through hole of the seal, and the elastic retainer, and then connect it to the port on the equipment body. Next, the elastic retainer is installed onto the equipment body, and the seal is housed within the elastic retainer. Finally, the connecting housing is fixedly connected to the equipment body, completing the entire connection process. Since the connection process mainly involves three core components—the elastic retainer, the seal, and the connecting housing—the number of parts required for installation is reduced, making the installation process simpler and more efficient, thus improving the equipment's installation efficiency. Furthermore, during the connection process between the connecting housing and the equipment body, the elastic retainer undergoes elastic deformation, applying a clamping force to the seal, ensuring a tight fit against the cable's outer wall, effectively improving sealing and waterproofing performance, thereby enhancing the reliability of equipment operation.

[0033] In one possible implementation, the resilient retainer includes: a fixed portion connected to the device body on one side having a port, and multiple resilient arms extending along the fixed portion on the side opposite to the device body. The multiple resilient arms are spaced apart on the outer periphery of the seal and are capable of elastic deformation to abut against the surface of the seal.

[0034] During the connection process between the housing and the device body, multiple elastic arms undergo elastic deformation under stress, thereby applying clamping force to the seal and ensuring a tight fit against the cable's outer wall. This not only improves connection stability but also achieves excellent sealing performance, thereby enhancing the operational reliability of the communication equipment.

[0035] In one possible implementation, the resilient retainer has a receiving space comprising: a first cavity segment and a second cavity segment that are in communication; the first cavity segment is closer to the device body than the second cavity segment, and the inner diameter of the first cavity segment is smaller than the inner diameter of the second cavity segment, so as to form a first annular limiting surface between the first cavity segment and the second cavity segment. The seal is located within the second cavity segment and is in contact with the first annular limiting surface.

[0036] The first annular limiting surface provides reliable axial support for the seal. During assembly, the seal is stably confined within the second cavity segment enclosed by the elastic retainer, effectively preventing the seal from shifting during installation and thus improving installation stability.

[0037] In one possible implementation, the resilient retainer has multiple snap-fit ​​protrusions on the side facing the device body for connection with the device body.

[0038] It effectively prevents the elastic retainer from shifting during use, thereby improving the stability of the connection between the elastic retainer and the equipment body. Attached Figure Description

[0060] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0061] This application provides a communication device. For example, the communication device in this application can be a customer premises equipment (CPE), an outdoor camera, a monitoring device, or other devices that require power supply via Ethernet. This application does not specifically limit the communication device.

[0062] Please refer to Figure 1 , Figure 2 and Figure 3 , Figure 1 This is a schematic diagram of the structure of a communication device provided in an embodiment of this application. Figure 2 This is an exploded view of a communication device provided in an embodiment of this application. Figure 3 This is a schematic diagram of the structure of a device body provided in an embodiment of this application.

[0063] The communication device may include a device body 100, which may have a port 101. For example, the port 101 may be an Ethernet interface for connection to a cable 001 to enable data transmission and power supply. The cable 001 can transmit both data signals and power, and may be referred to as a PoE (Power over Ethernet) cable. Through this PoE cable, the communication device can not only achieve high-speed data communication, but also power the device without laying additional power cables, thereby simplifying the wiring structure and reducing installation costs.

[0064] Since cable 001 needs to be electrically connected to port 101 in device body 100, this application embodiment provides a connection component that can be applied in the above-mentioned communication device, such as... Figure 2 As shown, the connection assembly may include a resilient retainer 200, which may be connected to the side of the device body 100 having a port 101.

[0065] Figure 4 This is a structural schematic diagram of a sealing element provided in an embodiment of this application. See Figure 2 and Figure 4 The connection assembly may also include a seal 300, which may have a through hole N for the cable 001 to pass through. A resilient retainer 200 is sleeved over the seal 300, and the through hole N and the resilient retainer 200 are used for the cable 001 to pass through and connect to the port 101 in the device body 100.

[0066] like Figure 1 and Figure 2 As shown, the connection assembly may also include a connection housing 400, which can be fitted onto the elastic retainer 200 and connected to the device body 100.

[0067] The elastic retainer 200 in the connecting assembly is capable of elastic deformation and is used to abut against the surface of the seal 300.

[0068] In this embodiment, when a user connects cable 001 to a communication device, the cable 001 only needs to pass through the connecting housing 400, the through hole N of the seal 300, and the elastic retainer 200 in sequence, and connect to the port 101 on the device body 100. Then, the elastic retainer 200 is installed onto the device body 100, and the seal 300 is housed within the elastic retainer 200. Finally, the connecting housing 400 is fixedly connected to the device body 100, thus completing the entire connection process. Since the connection process mainly involves three core components—the elastic retainer 200, the seal 300, and the connecting housing 400—the number of components required for installation is reduced, making the installation process simpler and more efficient, thereby improving the installation efficiency of the device. Furthermore, during the connection process between the connecting housing 400 and the device body 100, the elastic retainer 200 undergoes elastic deformation and applies a clamping force to the seal 300, causing it to tightly adhere to the outer wall of the cable 001, thereby effectively improving sealing and waterproof performance, and thus enhancing the reliability of the device operation.

[0069] Figure 5 This is a schematic diagram of the structure of an elastic retainer provided in an embodiment of this application. For example... Figure 5 As shown, the elastic retainer 200 in the connection assembly may include: a fixed part 201 and a plurality of elastic arms 202 connected to each other; the fixed part 201 may be connected to the side of the device body 100 having a port 101, and the plurality of elastic arms 202 may extend along the side of the fixed part 201 away from the device body 100.

[0070] Among them, multiple elastic arms 202 in the elastic retainer 200 can be distributed at intervals on the outer periphery of the seal 300, and the multiple elastic arms 202 can elastically deform to abut against the surface of the seal 300.

[0071] During the connection process between the housing 400 and the device body 100, multiple elastic arms 202 undergo elastic deformation under force, thereby applying a clamping force to the seal 300, making it tightly fit against the outer wall of the cable 001. This not only improves the stability of the connection but also achieves excellent sealing performance, thereby enhancing the operational reliability of the communication equipment.

[0072] Figure 6 yes Figure 5 The cross-sectional view of the elastic retainer is shown. Figure 7 This is an assembly diagram of an elastic retainer and a seal provided in an embodiment of this application. Figure 6 and Figure 7As shown, the elastic retainer 200 in the connecting assembly may have a receiving space C, which may include: a first cavity segment C1 and a second cavity segment C2 that are connected to each other; wherein the first cavity segment C1 is closer to the device body 100 than the second cavity segment C2, and the inner diameter of the first cavity segment C1 is smaller than the inner diameter of the second cavity segment C2, so as to form a first annular limiting surface A1 between the first cavity segment C1 and the second cavity segment C2.

[0073] Here, the first cavity C1 is located within the fixing part 201, constituting the portion of the accommodating space C near the device body 100; the second cavity C2 is formed by multiple elastic arms 202 surrounding it, constituting the portion of the accommodating space C away from the device body 100. Specifically, both the first cavity C1 and the second cavity C2 are cylindrical structures, and the transition area between them forms a complete and continuous circular edge, distributed around the central axis of the elastic retainer 200, which is the first annular limiting surface A1.

[0074] The seal 300 in the connecting assembly can be located within the second cavity C2 and in contact with the first annular limiting surface A1.

[0075] The first annular limiting surface A1 provides reliable axial support for the seal 300. During assembly, the seal 300 is stably confined within the second cavity C2 enclosed by the elastic retainer 200, effectively preventing the seal 300 from shifting during installation and thus improving installation stability.

[0076] In the embodiments of this application, please refer to Figure 5 and Figure 8 , Figure 8 This is a cross-sectional view of a device body provided in an embodiment of this application. The elastic retainer 200 in the connecting assembly has a plurality of first latching portions 203 on the side facing the device body 100, and the plurality of first latching portions 203 are distributed circumferentially along the elastic retainer 200; the device body 100 has a plurality of second latching portions 103 that cooperate with the plurality of first latching portions 203.

[0077] In this configuration, each of the multiple first latching parts 203 corresponds one-to-one with a multiple of the multiple second latching parts 103, with each first latching part 203 latching with its corresponding second latching part 103. For example, there are two of each of the multiple first latching parts 203 and the multiple second latching parts 103.

[0078] Through the precise matching and snap-fitting of the first snap-fit ​​part 203 and the second snap-fit ​​part 103, a reliable mechanical connection is achieved between the elastic retainer 200 and the device body 100. This snap-fit ​​structure not only improves the overall mechanical strength of the communication device but also enhances its resistance to external vibration or impact. Furthermore, compared to traditional screws or other fixing methods, this snap-fit ​​structure allows for assembly without the need for additional tools, effectively simplifying installation steps, reducing assembly complexity, and thus improving assembly efficiency and ease of operation.

[0079] In some examples, such as Figure 5 and Figure 8 As shown, one of the first latching portion 203 and the second latching portion 103 is a latching protrusion P, and the other is a latching groove Q; at least a portion of the latching protrusion P is located within the latching groove Q. For example, all of the latching protrusion P is located within the latching groove Q.

[0080] By fully embedding the snap-fit ​​protrusion P into the snap-fit ​​groove Q, displacement of the elastic retainer 200 during use can be effectively prevented, thereby improving the connection stability between the elastic retainer 200 and the equipment body 100. Simultaneously, because the snap-fit ​​protrusion P and the snap-fit ​​groove Q have a clear mating relationship, they can guide the accurate alignment and installation of the elastic retainer 200, avoiding misalignment and improving assembly efficiency.

[0081] In this application example, the first latching portion 203 and the second latching portion 103 can be flexibly designed as complementary concave and convex shapes, that is, the first latching portion 203 and the second latching portion 103 can be interchanged as latching protrusions P or latching grooves Q; if the first latching portion 203 is designed as a latching protrusion P, then the second latching portion 103 matches as a latching groove Q; conversely, if the first latching portion 203 is designed as a latching groove Q, then the second latching portion 103 is adapted to be a latching protrusion P. For clarity, this application uses the example of the first latching portion 203 being a latching protrusion P and the second latching portion 103 being a latching groove Q for illustration.

[0082] In some examples, such as Figure 2 and Figure 3 As shown, the device body 100 in the connection assembly may have a protrusion 102 on the side facing the connection housing 400, and the connection housing 400 may be connected to the protrusion 102.

[0083] During the connection process between the housing 400 and the protrusion 102 in the device body 100, the multiple elastic arms 202 in the elastic retainer 200 will undergo elastic deformation and apply clamping force to the seal 300, so that it fits tightly against the outer wall of the cable 001, thereby effectively improving the sealing and waterproof performance, and thus improving the reliability of the communication equipment operation.

[0084] In this embodiment, the connecting housing 400 is threadedly connected to the protrusion 102.

[0085] For example, the inner wall of the connecting housing 400 is provided with an internal thread section, and the outer wall of the protrusion 102 is provided with a corresponding external thread section. The two are connected by threaded engagement. In this way, the position of the connecting housing 400 relative to the device body 100 can be adjusted by rotating the connecting housing 400. In addition, the threaded connection design simplifies the installation process, allowing for quick assembly without additional tools and improving assembly efficiency.

[0086] In the embodiments of this application, please refer to Figure 9 , Figure 9 This is a schematic diagram of another elastic retaining member provided in an embodiment of this application. The fixing part 201 in the elastic retaining member 200 may include: a first sub-fixing part 2011 and a second sub-fixing part 2012, wherein the first sub-fixing part 2011 is closer to the device body 100 than the second sub-fixing part 2012.

[0087] like Figure 9 As shown, the outer diameter of the first sub-fixing part 2011 in the fixing part 201 is smaller than the outer diameter of the second sub-fixing part 2012, so as to form a second annular limiting surface A2 between the first sub-fixing part 2011 and the second sub-fixing part 2012. Specifically, both the first sub-fixing part 2011 and the second sub-fixing part 2012 have a cylindrical structure, and the transition area between them forms a complete and continuous circular edge. This edge is distributed around the central axis of the elastic retainer 200, which is the second annular limiting surface A2.

[0088] Figure 10 This is an exploded view of another communication device provided in an embodiment of this application. For example... Figure 10 As shown, the connecting assembly may also include a sealing gasket 500, which may be located between the second annular limiting surface A2 and the end of the protrusion 102 away from the device body 100.

[0089] For example, the sealing gasket 500 may be made of a resilient material, such as at least one of rubber, silicone, or thermoplastic elastomer.

[0090] To achieve a better sealing effect, the sealing gasket 500 can be a ring structure.

[0091] By providing a sealing gasket 500 between the second annular limiting surface A2 and the end of the protrusion 102 facing away from the equipment body 100, after the elastic retainer 200 and the equipment body 100 are engaged, the sealing gasket 500 is subjected to the combined action of the second annular limiting surface A2 and the end of the protrusion 102, resulting in compression deformation. This forms a sealing barrier between the connecting housing 400 and the equipment body 100, effectively preventing external moisture, dust, and other contaminants from entering the equipment body 100. Furthermore, since the positioning of the sealing gasket 500 is clearly supported by the second annular limiting surface A2, potential misalignment or displacement during assembly is avoided, improving assembly accuracy.

[0092] In one possible scenario, when cable 001 is connected to the communication equipment, the rotation of the connection housing 400 may cause the elastic retainer 200 to rotate as well. This, in turn, causes the seal 300 to rotate due to the friction between the elastic retainer 200 and the seal 300, resulting in the cable 001 being twisted and deformed, which in turn leads to a poor connection between cable 001 and the communication equipment.

[0093] In the embodiments of this application, such as Figure 5 and Figure 8 As shown, the outer wall of the fixing portion 201 in the elastic retainer 200 has at least one first positioning surface S1, and the inner wall of the protrusion 102 on the device body 100 has at least one second positioning surface S2, and the first positioning surface S1 and the second positioning surface S2 are in contact. For example, there are two first positioning surfaces S1 and two positioning surfaces S2. The first positioning surface S1 can be a rectangular planar area formed on the outer wall of the fixing portion 201, and the second positioning surface S2 can be a corresponding rectangular planar area formed on the inner wall of the protrusion 102. These rectangular planar structures can be formed by machining, mold forming, or other processes to ensure their shape accuracy and fit performance.

[0094] When the connecting housing 400 is connected to the protrusion 102 via threaded rotation, the first positioning surface S1 and the second positioning surface S2 are tightly fitted together. Because the positioning surfaces adopt a rectangular planar structure, when the elastic retainer 200 tends to rotate, the two rectangular planes will directly contact each other, thus restricting its rotational freedom. After assembly, the elastic retainer 200 is reliably fixed to the device body 100 and cannot rotate relative to it. Therefore, it will not transmit rotational force through the seal 300, avoiding torsional deformation of the seal and cable 001. This ensures a stable connection between the cable 001 and the communication equipment, improving the reliability of the equipment operation.

[0095] In this embodiment, the connecting components are compatible with a variety of cables 001, and their cross-sectional shapes also vary. To effectively seal and secure different types of cables 001, the cross-sectional shape of the through hole N in the sealing member 300 for the cable 001 is also designed with various adaptation forms to meet the adaptation requirements of different cables 001. For clarity, this embodiment will be illustrated using the following two optional implementation methods as examples:

[0096] For the first optional implementation method, please refer to... Figure 4 and Figure 11 , Figure 11 yes Figure 4 The diagram shows a cross-sectional view of the seal. The through hole N in the seal 300 has a circular cross-sectional shape. Here, the cross-section refers to a plane perpendicular to the extension direction of the cable 001. Furthermore, the diameter of the through hole N gradually increases along the first direction X; or, the diameter of the through hole N gradually decreases along the first direction X; wherein, the first direction X is the insertion / removal direction of the cable 001.

[0097] By employing a gradually changing diameter design for the through hole N, the seal 300 can accommodate cables 001 with varying outer diameters, thus enhancing its versatility. Furthermore, because the diameter of the through hole N gradually increases or decreases in the insertion / removal direction of the cable 001, the seal 300 achieves a good fit and seal regardless of the direction the cable 001 is inserted. Consequently, there is no need to specifically limit the installation direction of the seal 300 during assembly, significantly improving assembly flexibility.

[0098] In some examples, the diameter of the through hole N ranges from 5 mm to 8 mm. For example, the diameter of the through hole N can be 5.5 mm, 6 mm, or 7 mm. Of course, the diameter of the through hole N can also be other values, as long as the diameter of the through hole N is guaranteed to be within the range of 5 mm to 8 mm.

[0099] For the second optional implementation method, please refer to... Figure 12 , Figure 12 This is a schematic diagram of another sealing element provided in an embodiment of this application. The through hole N in the sealing element 300 has a rectangular cross-sectional shape, where the cross-section refers to a plane perpendicular to the extension direction of the cable 001. In this case, the cross-section of the through hole N is designed to be rectangular, which can be applied to cables 001 with rectangular or other non-circular cross-sections.

[0100] In this embodiment, the seal 300 in the connecting assembly is an elastic seal. For example, the seal 300 may be made of an elastic material. For instance, the material of the seal 300 may be silicone rubber, fluororubber, or nitrile rubber, etc.

[0101] During the connection process between the housing 400 and the device body 100, multiple elastic arms 202 undergo elastic deformation under external force, thereby applying a clamping force to the seal 300. Since the seal 300 is made of elastic material, it can undergo corresponding elastic deformation after being subjected to the clamping force from the multiple elastic arms 202, causing its inner wall to tightly adhere to the outer wall of the cable 001. This not only improves the stability of the connection but also achieves excellent sealing performance, thereby enhancing the reliability of the communication equipment.

[0102] To more clearly describe the installation process of the communication equipment, the following detailed explanation will be provided in conjunction with the accompanying drawings. Please refer to the attached diagrams. Figure 13 and Figure 14 , Figure 13 This is an exploded view of another communication device provided in the embodiments of this application, used to illustrate the connection relationship between the elastic retaining member 200 and the device body 100. Figure 14 This is an exploded view of another communication device provided in an embodiment of this application. For example... Figure 13 and Figure 14 As shown, when the user connects cable 001 to the communication device, cable 001 is first passed through the connecting housing 400, the through hole N of the seal 300, and the elastic retainer 200 in sequence, and then connected to port 101 on the device body 100. Then, the elastic retainer 200 is installed onto the device body 100. This process achieves the desired result. Figure 14 The structure. Please refer to... Figure 15 , Figure 15 This is another exploded view of a communication device provided in an embodiment of this application, showing the seal 300 housed within the elastic retainer 200, thus achieving... Figure 15 The structure. Please refer to... Figure 16 , Figure 16 This is a schematic diagram of another communication device provided in an embodiment of this application. The entire connection process is completed by fixing the connecting housing 400 to the device body 100. Figure 16 The structure.

[0103] The connection component provided in this application can be used not only in the aforementioned communication devices, but also in vehicle-mounted or medical devices.
