[0040] This application discloses a connector assembly and a cable connector, which includes some or all of the technical features of the following embodiments; that is, the connector assembly and the cable connector include some or all of the following structures. In one embodiment of this application, a connector assembly includes a housing, an inner sleeve, a sealing sleeve, and a waterproof sealing ring; the inner sleeve is fitted inside the housing, and one end of the inner sleeve mates with the housing to form a terminal, and the other end mates with the housing to form a plug-in terminal. The terminal is used to connect a cable, and the plug-in terminal is used to connect to a socket so that the cable can transmit signals; the inner sleeve has a position that abuts against the housing so that a receiving area is formed between the inner sleeve and the housing at the terminal; the sealing sleeve is disposed in the receiving area, and when the cable is connected, the cable passes through the sealing sleeve, and the sealing sleeve is deformed by the force of the inner sleeve and the housing to seal the terminal; at the plug-in terminal, the waterproof sealing ring is fitted outside the inner sleeve, so that when the socket is connected, the waterproof sealing ring abuts against the inner sleeve and the socket respectively. The aforementioned connector assembly, through the cooperation of a housing, inner sleeve, sealing sleeve, and waterproof sealing ring, provides a waterproof seal for the cable connection, meeting waterproofing requirements. Furthermore, the sealing sleeve achieves a seal at the terminal through deformation under stress between the housing and inner sleeve, offering simplicity and reliability. Additionally, the structural design of the waterproof sealing ring and inner sleeve facilitates quick and secure connection to the socket, enabling the installation of the connector assembly. Moreover, simply assembling the sealing sleeve into the receiving area achieves terminal sealing, thus offering advantages such as simple structure and ease of assembly, minimizing the risk of losing small parts. The following section will further elaborate on this. Figures 1 to 17 The connection plug assembly and cable connector are described in detail below.

[0041] In some embodiments, a connector assembly 100, such as Figure 1 and Figure 2 As shown, it includes a housing 110, an inner sleeve 120, a sealing sleeve 130, and a waterproof sealing ring 140; the inner sleeve 120 is fitted inside the housing 110, and one end of the inner sleeve 120 mates with the housing 110 to form a terminal 101, and the other end mates with the housing 110 to form a plug-in terminal 102, combined with... Figure 10 and Figure 11 The terminal 101 is used to connect the cable 200, in conjunction with Figure 17 The plug-in terminal 102 is used to connect to the socket 300 so that the cable 200 can transmit signals; combined with Figure 6 and Figure 7The inner sleeve 120 has a position that abuts against the outer shell 110, so that a receiving area 103 is formed between the inner sleeve 120 and the outer shell 110 at the terminal 101; the sealing sleeve 130 is disposed in the receiving area 103, and when the cable 200 is connected, the cable 200 passes through the sealing sleeve 130, and the sealing sleeve 130 is deformed by the force of the inner sleeve 120 and the outer shell 110 to seal the terminal 101; at the plug end 102, the waterproof sealing ring 140 is fitted outside the inner sleeve 120, so that when the socket 300 is connected, the waterproof sealing ring 140 abuts against the inner sleeve 120 and the socket 300 respectively. This design, through the cooperation of the outer shell 110, inner sleeve 120, sealing sleeve 130, and waterproof sealing ring 140, achieves a sealing and waterproof function for the cable 200 connection, meeting waterproof requirements. Furthermore, the sealing sleeve 130 achieves a seal on the terminal 101 by deforming under force between the outer shell 110 and the inner sleeve 120, offering advantages of simplicity and reliability. Additionally, the structural design of the waterproof sealing ring 140 in conjunction with the inner sleeve 120 facilitates quick and secure connection of the socket 300, thereby enabling the installation of the connector assembly 100. Moreover, simply assembling the sealing sleeve 130 into the receiving area 103 is sufficient to seal the terminal 101, thus offering advantages of simple structure and ease of assembly, minimizing the risk of losing small parts.

[0042] In various embodiments, the inner kit 120 is fitted within the outer casing 110, meaning that the inner kit 120 is at least partially located within the outer casing 110. As an example, in conjunction with... Figure 1 and Figure 3 The outer casing 110 has a first inner cavity 112, and the inner sleeve 120 is partially or entirely located within the first inner cavity 112. One end of the inner sleeve 120 mates with the outer casing 110 to form a terminal 101, which is then connected to... Figure 10 and Figure 11The terminal 101 is used to connect the cable 200. The other end of the inner sleeve 120 cooperates with the outer shell 110 to form a plug-in terminal 102. The plug-in terminal 102 is used to connect to the socket 300 so that the cable 200 can transmit signals. As an example, the wire of the cable 200 enters the inner sleeve 120 from the terminal 101, and the connector of the cable 200 connects to the wire of the cable 200 from the plug-in terminal 102 and is located in the inner sleeve 120. Those skilled in the art will understand that, in specific applications, the connector assembly 100 may also have a component in the inner sleeve 120 for fixing the connector of the cable 200. This design, on the one hand, through the tight fit between the sealing sleeve 130 and the inner sleeve 120 and the outer shell 110, will provide multiple layers of sealing for the cable 200 due to deformation when the cable 200 is connected, preventing moisture, dust and other impurities from entering from the terminal 101, greatly improving the reliability of the connector assembly 100 in humid environments and meeting the requirements of high waterproof application scenarios. On the other hand, at the plug end 102, the waterproof sealing ring 140 is fitted over the inner sleeve 120. When the socket 300 is connected, it abuts against both the inner sleeve 120 and the socket 300, providing radial support for the connection. This effectively prevents the plug from loosening due to vibration or external force, ensuring stable signal transmission between the cable 200 and the socket 300, and reducing transmission interruptions or data loss caused by poor contact. Furthermore, simply assembling the sealing sleeve 130 into the receiving area 103 allows the sealing of the terminal 101 to be achieved through the force exerted by the inner sleeve 120 and the outer shell 110. This simplifies the assembly process, reduces the technical requirements for assembly workers and the assembly error rate, improves production efficiency, and avoids incomplete assembly due to the loss of small parts. On the other hand, if a component for fixing the cable 200 connector is provided in the inner kit 120, it can enhance the fixation of the cable 200 within the inner kit 120, preventing displacement or deformation of the cable 200 due to uneven force during insertion, further improving the overall structural stability of the connector assembly 100 and extending its service life. Furthermore, the connector assembly 100 has a simple and versatile design, adaptable to different types and specifications of cables 200 and sockets 300, and has good applicability in various fields such as industrial control, communication equipment, automotive electronics, and medical instruments, providing reliable solutions for cable connections in different scenarios, such as applications in mobile communication products.

[0043] In some of these embodiments, such as Figure 7 and Figure 8As shown, a gap 104 exists between the inner component 120 and the outer shell 110, allowing the inner component 120 to rotate within the outer shell 110. As an example, in an embodiment with a body 121 and a shell 111, the body 121 rotates within the shell 111 via the gap 104, facilitating the assembly of the inner component 120 into the outer shell 110. This design, on the one hand, allows the inner component 120 to rotate flexibly during assembly, making it easier for operators to smoothly insert the inner component 120 into the outer shell 110, reducing assembly difficulty and time, and improving production efficiency. On the other hand, during assembly, because the inner component 120 can rotate within the outer shell 110, even with slight deviations in the assembly angle, it can be adjusted to the correct position through rotation, thereby increasing the assembly success rate and reducing the defect rate caused by improper assembly. On the other hand, the gap 104 provides the inner kit 120 with a certain amount of room to move, allowing it to adapt to housings 110 of different sizes or shapes, thus enhancing the versatility and adaptability of the connector assembly 100 and facilitating its use in various application scenarios. Furthermore, since the inner kit 120 can rotate freely within the housing 110, precise alignment using complex tools may not be required during assembly, further simplifying the assembly process and reducing production costs.

[0044] The outer casing 110 is fitted over the inner casing 120. In some embodiments, the outer casing 110 has a force-applying position 115 for applying force to the outer casing 110 through the force-applying position 115. In some embodiments, the outer casing 110 has an identification portion 116 for indicating the assembly direction of the outer casing 110 with the connected dust cover 150 or socket 300. That is, when installing or removing the outer casing 110 and the dust cover 150, or when installing or removing the outer casing 110 and the socket 300, the installation or removal direction can be known through the identification portion 116. As an example, the outer casing 110 has a force-applying position 115 on its housing 111 for applying force to the outer casing 110 through the force-applying position 115; or, the outer casing 110 has an identification portion 116 on its housing 111 for indicating the assembly direction of the inner casing 120 with the outer casing 110. This design, by providing a force application point 115 on the housing 111, allows operators to more easily apply force to the outer casing 110. For example, during installation or disassembly, the force application point 115 provides a clear point of application, reducing damage caused by improper force during assembly and improving assembly efficiency. Furthermore, the marking section 116 clearly indicates the correct assembly direction of the inner component 120 and the housing 110, avoiding assembly failure or functional abnormalities due to incorrect assembly direction, thereby improving assembly accuracy and reliability. On the other hand, the design of the force application point 115 and the marking section 116 makes the assembly process more intuitive and simple, reducing assembly time and error rates, thus significantly improving production efficiency and reducing production costs. Moreover, the design of the force application point 115 and the marking section 116 makes the installation and use of the connector assembly 100 more convenient, reducing problems caused by improper operation and improving the overall user experience. Furthermore, when maintenance or component replacement of the connector assembly 100 is required, the force application point 115 and the marking section 116 help users complete the operation quickly and accurately, reducing maintenance time and workload. On the other hand, by clearly defining the force application point 115 and the marking part 116, the correct assembly between the inner kit 120 and the outer shell 110 can be ensured, reducing structural loosening or functional failure caused by improper assembly, thereby improving the overall reliability and service life of the product.

[0045] In various embodiments, the inner sleeve 120 has a position that abuts against the outer shell 110, forming a receiving area 103 between the inner sleeve 120 and the outer shell 110 at the terminal 101; in some embodiments, the outer shell 110 has a protruding abutment 114, and the inner sleeve 120 has a protruding protrusion 124; when the inner sleeve 120 is fitted inside the outer shell 110, the protrusion 124 abuts against the abutment 114, thereby limiting the force exerted on the sealing sleeve 130 by the inner sleeve 120 and the outer shell 110, thus protecting the sealing sleeve 130; in some embodiments, the outer shell 110 has a protruding abutment 114 inside the housing 111, and the inner sleeve 120 has a protruding protrusion 124 outside the body 121; when the body 121 is fitted inside the housing 111, the protrusion 124 abuts against the abutment 114, thereby limiting the extreme position of the body 121 within the housing 111. This design, on the one hand, ensures the position of the receiving area 103 by the contact between the protrusion 124 and the abutment 114, preventing the sealing sleeve 130 from being excessively compressed. It also provides a stable and uniform force to the sealing sleeve 130, causing it to deform at the terminal 101, thus tightly fitting the cable 200 and effectively preventing moisture and dust from entering, ensuring the sealing performance of the connector assembly 100. On the other hand, the abutment 114 and the protrusion 124 increase the contact area and stability between the inner sleeve 120 and the outer shell 110, preventing the inner sleeve 120 from loosening or shifting after assembly, and improving the overall structural stability of the connector assembly 100. Furthermore, this design means that the sealing effect of the sealing sleeve 130 does not rely on additional fasteners or complex assembly processes. Sealing is achieved simply by assembling the inner sleeve 120 with the outer shell 110 and then installing the dust cover 150 or the socket 300, simplifying the assembly process and improving assembly reliability and consistency. On the other hand, the fit between the protrusion 124 and the abutment 114 can be adjusted according to the sealing sleeve 130 of different sizes, which enhances the adaptability of the connector assembly 100 to cables 200 of different specifications, enabling it to be widely used in a variety of application scenarios.

[0046] In each embodiment, the sealing sleeve 130 is disposed in the receiving area 103. When the cable 200 is connected, the cable 200 passes through the sealing sleeve 130, and the sealing sleeve 130 deforms under the force of the inner sleeve 120 and the outer shell 110 to seal the terminal 101. That is, the sealing sleeve 130 has a compression-type structure design, achieving a seal through compression. Thus, the sealing sleeve 130, the inner sleeve 120, and the outer shell 110 achieve axial and radial sealing through compression. Furthermore, the sealing sleeve 130 has a corrugated design, combining waterproof sealing with elastic locking functions, which facilitates contraction to form a seal, thereby achieving compression-type waterproof sealing.

[0047] In some embodiments, the sealing sleeve 130 has a corrugated shape, that is, the sealing sleeve 130 has a corrugated design, including a corrugated outer shape and / or corrugated grooves therein. In some embodiments, at the terminal 101, the sealing sleeve 130 is pre-connected to the inner sleeve 120 or the outer shell 110. As an example, the sealing sleeve 130 is bonded to the inner sleeve 120 by heat fusion; or, both the sealing sleeve 130 and the inner sleeve 120 are plastic parts, and the sealing sleeve 130 is integrally formed with the inner sleeve 120; or, the sealing sleeve 130 is bonded to the outer shell 110 by heat fusion; or, both the sealing sleeve 130 and the inner sleeve 120 are plastic parts, and the sealing sleeve 130 is integrally formed with the outer shell 110. As an example, the sealing sleeve 130 is integrally formed with the inner sleeve 120 or the outer shell 110, for example, as an integrally formed plastic part. This facilitates production and processing and product sealing, and significantly improves product structural stability and production convenience.

[0048] Specifically, this design, on the one hand, ensures a tight fit between the sealing sleeve 130 and the inner kit 120 or the outer shell 110 through pre-connection, enhancing sealing performance and effectively preventing moisture and dust from entering, thereby improving the waterproof and dustproof rating of the connector assembly 100. Furthermore, pre-connection eliminates the need for additional fixing or adjustment steps during assembly of the sealing sleeve 130, reducing assembly steps, assembly difficulty and time, and improving production efficiency. On the other hand, pre-connection makes the sealing sleeve 130 and the inner kit 120 or the outer shell 110 form a whole, enhancing the structural stability of the entire assembly and reducing the risk of parts loosening or falling off due to vibration or external forces. Moreover, pre-connection ensures the connection quality between the sealing sleeve 130 and the inner kit 120 or the outer shell 110, reducing sealing problems caused by assembly errors and improving the overall consistency and reliability of the product. Finally, pre-connection also reduces the need for additional sealing materials or fasteners during assembly, lowering production costs.

[0049] In various embodiments, at the plug-in end 102, the waterproof sealing ring 140 is fitted over the inner sleeve 120, so that when the socket 300 is connected, the waterproof sealing ring 140 abuts against the inner sleeve 120 and the socket 300 respectively. In some embodiments, combined with Figure 4 and Figure 7 At the insertion end 102, the inner sleeve 120 or its body 121 is provided with a groove 126. The waterproof sealing ring 140 is fitted over the groove 126 to maintain the relative position of the waterproof sealing ring 140 and the inner sleeve 120, for example, maintaining the relative position of the waterproof sealing ring 140 and the inner sleeve 120 in the axial direction. In this embodiment, the protrusion 124 is provided at the end 125 of the inner sleeve 120 near the insertion end 102. This design, on the one hand, provides a clear installation position for the waterproof sealing ring 140, preventing it from shifting or sliding in the axial direction, thereby ensuring that the waterproof sealing ring 140 is always in the correct position when connected to the socket 300 and performs its sealing function. On the other hand, fixing the waterproof sealing ring 140 with the groove 126 ensures a tight fit when connected to the socket 300, effectively preventing moisture from entering from the plug end 102 and improving the waterproof performance of the connector assembly 100. Furthermore, the design of the groove 126 makes the installation of the waterproof sealing ring 140 more intuitive and convenient, reducing the need for adjusting the sealing ring position during assembly, improving assembly efficiency, and reducing assembly difficulty. Moreover, fixing the position of the waterproof sealing ring 140 reduces the risk of seal failure due to sealing ring displacement, thereby improving the overall reliability and service life of the connector assembly 100. Additionally, this design allows the connector assembly 100 to maintain stable sealing performance in different operating environments, making it suitable for various scenarios requiring waterproof protection. This enhances the product's versatility, allowing it to be used as a waterproof connector or a sealed connector. It provides a waterproof solution for cable connectors using the connector assembly 100, with PG waterproof connector specifications achieving waterproof ratings of IP66 and even IP67, thus helping to solve the problem of waterproof sealing at outdoor equipment ports.

[0050] In some of these embodiments, such as Figure 12 and Figure 13 As shown, the connector assembly 100 also includes a dust cover 150, combined with... Figure 14 The dust cover 150 is detachably inserted into the plug-in end 102, and is used to abut against the inner sleeve 120 and the waterproof sealing ring 140, and to snap onto the outer shell 110, and apply pressure to the sealing sleeve 130, when the plug-in end 102 is not connected to the socket 300. Figure 15 and Figure 16In this way, with the connector assembly 100 connected to the cable 200, the dust cover 150, together with the inner sleeve 120 and the outer shell 110, can seal the end of the product, improving the sealing effect of the terminal 101. It also serves as a dustproof measure during daily transportation or storage, protecting the connector assembly 100 and the assembled cable 200. During installation, simply remove the dust cover 150 and then install the connector assembly 100 with the cable 200 onto the socket 300.

[0051] Exemplary examples show that in each embodiment, only two hardware structures, the outer shell 110 and the inner sleeve 120, are used to compress the sealing sleeve 130. No additional deformation structures are needed to restrict the position of the sealing sleeve 130, thus resulting in a simple structure that is easy to assemble. As an example, combined with... Figure 3 and Figure 4 The sealing sleeve 130 has a through-slot 131 through which the cable 200 passes. In embodiments with the through-slot 131, the through-slot 131 may have different diameters to improve deformation sealing under pressure. In some embodiments, combined with... Figure 6 and Figure 7 At the terminal 101, the inner sleeve 120 or its body 121 has a protruding limiting area 129, which is wider than the cable 200. The sealing sleeve 130 has a portion located within the limiting area 129; that is, the sealing sleeve 130 can have portions of different sizes to enhance the deformation sealing effect under pressure. This design, on the one hand, allows the sealing sleeve 130 to better fit the cable 200 and the inner sleeve 120 under pressure, forming a tighter seal, effectively preventing moisture and dust from entering, and improving the waterproof and dustproof performance of the connector assembly 100. On the other hand, the limiting area 129 being wider than the cable 200 allows the sealing sleeve 130 to adapt to cables of different diameters, enhancing the versatility and flexibility of the connector assembly 100, making it suitable for various application scenarios. Furthermore, the limiting area 129 provides a fixed position for the sealing sleeve 130, preventing displacement during assembly or use, thereby improving the structural stability of the entire assembly. On the other hand, the sealing sleeve 130 has parts of different sizes, which can produce more uniform deformation under pressure, further improving the sealing effect, while reducing the risk of damage to the sealing sleeve due to excessive local pressure.

[0052] For example, in an embodiment with a second wire hole 123, the limiting region 129 is wider than the second wire hole 123; that is, for a circular cross-section structural member, the diameter of the limiting region 129 is larger than the diameter of the second wire hole 123. This design helps to increase the different deformation effects at the contact positions between the sealing sleeve 130 and the cable 200, thereby improving the sealing effect of the sealing sleeve 130 on the cable 200. Furthermore, the limiting region 129 being wider than the second wire hole 123 allows the sealing sleeve 130 to fit more tightly against the cable 200 under pressure, forming a multi-layer seal that effectively prevents moisture and dust from entering, thus improving the waterproof and dustproof rating of the connector assembly 100.

[0053] In some of these embodiments, such as Figure 3 and Figure 4 As shown, the outer casing 110 includes a housing 111, and a first inner cavity 112 and a first wire hole 113 communicating with the first inner cavity 112 are formed in the housing 111; combined with Figure 5 and Figure 6 The inner fitting 120 includes a body 121, and a second inner cavity 122 and a second wire hole 123 communicating with the second inner cavity 122 are formed in the body 121; the body 121 is fitted into the housing 111, and one end of the body 121 cooperates with the housing 111 to form the terminal 101, and the other end cooperates with the housing 111 to form the plug-in terminal 102; combined Figure 7The body 121 has a position that abuts against the housing 111, so that at the terminal 101, the receiving area 103 is formed between the body 121 and the housing 111. The first wire hole 113 and the second wire hole 123 are both located at the terminal 101. When the cable 200 is connected, the cable 200 passes sequentially through the first wire hole 113, the sealing sleeve 130, and the second wire hole 123. The sealing sleeve 130 is deformed by the force of the body 121 and the housing 111 to seal the first wire hole 113, the second wire hole 123, and the receiving area 103. As an example, the second inner cavity 122 is provided with a plug-in mechanism for connecting the cable 200; or it is provided with a connector for the cable 200. This design has several advantages. First, the cable 200 passes sequentially through the first wire hole 113, the sealing sleeve 130, and the second wire hole 123. The sealing sleeve 130 deforms under the force of the body 121 and the housing 111, tightly fitting the cable 200. This creates a multi-layered seal between the first wire hole 113, the second wire hole 123, and the receiving area 103, effectively preventing moisture and dust from entering through the terminal 101 and significantly improving the waterproof and dustproof performance of the connector assembly 100. Second, the body 121 of the inner sleeve 120 is fitted inside the housing 111 of the outer shell 110, forming the terminal 101 and the plug-in terminal 102. This fitted structure makes the entire assembly compact, enhancing overall structural stability and reducing the risk of component loosening due to vibration or external forces. Third, the receiving area 103 formed between the body 121 and the housing 111 provides a clear installation position for the sealing sleeve 130, making its assembly simpler and more accurate, reducing errors during assembly, and improving assembly efficiency and reliability. On the other hand, the design of the first wire hole 113 and the second wire hole 123 can accommodate cables 200 of different diameters, enhancing the versatility and flexibility of the connector assembly 100 and enabling it to be widely used in various application scenarios. Furthermore, the sealing sleeve 130 deforms under the force of the body 121 and the housing 111. This design allows the sealing sleeve 130 to produce more uniform deformation, further improving the sealing effect while reducing the risk of damage to the sealing sleeve due to excessive local pressure.

[0054] In this embodiment, the outer casing 110 has a slot 117 on the housing 111 to engage the socket 300 when connected, thereby improving the connection and sealing effect in conjunction with the inner sleeve 120 and the waterproof sealing ring 140. In some embodiments, such as Figure 3 and Figure 7As shown, the outer shell 110 has a protruding abutment 114 inside the housing 111, and the inner sleeve 120 has a protrusion 124 protruding outside the body 121. When the body 121 is fitted inside the housing 111, the protrusion 124 abuts against the abutment 114, causing the sealing sleeve 130 to deform under the force of the body 121 and the housing 111. In some embodiments, the protrusion 124 is integrally formed with the body 121; for example, the protrusion 124 and the body 121 are integrally formed plastic parts. This design, on the one hand, allows the abutment between the protrusion 124 and the abutment 114 to provide a stable and uniform force to the sealing sleeve 130, causing it to deform uniformly at the terminal 101, thereby tightly fitting the cable 200, effectively preventing moisture and dust from entering, and ensuring sealing performance. On the other hand, the engagement between the protrusion 124 and the abutment 114 increases the contact area and stability between the inner sleeve 120 and the outer shell 110, preventing the inner sleeve 120 from loosening or shifting after assembly, thus improving the overall structural stability of the connector assembly 100. Furthermore, the abutment between the protrusion 124 and the abutment 114 eliminates the need for additional fasteners or complex assembly processes to achieve the sealing effect of the sealing sleeve 130, simplifying the assembly process and improving assembly efficiency. Moreover, the protrusion 124 and the body 121 are integrally molded structural components. This design ensures a tight fit between components, reducing sealing problems caused by assembly errors and improving the overall consistency and reliability of the product. In addition, the integrally molded structural components reduce assembly steps in the production process, lowering production costs while improving the product's durability and service life.

[0055] In some embodiments, both the body 121 and the housing 111 are cylindrical. As an example, the outer shell 110 has an expansion end 118 near the plug end 102 to accommodate the socket 300, while simultaneously reducing the volume of other parts of the connector assembly 100, thus saving materials and reducing costs. In some embodiments, such as... Figure 8 As shown, the body 121 is provided with a threaded limiting portion 127 for limiting the circumferential position of the body 121 and the connected dust cover 150 or socket 300. In some embodiments, such as Figure 9 As shown, the main body 121 is provided with a strip-block limiting part 128 for limiting the circumferential position of the main body 121 and the connected dust cover 150 or socket 300. Thus, after the dust cover 150 or socket 300 is installed, the dust cover 150 or socket 300 is abutted and limited by the threaded limiting part 127 or the strip-block limiting part 128, maintaining the installation position of the dust cover 150 or socket 300 and preventing uncontrolled rotation on the main body 121. For example, in conjunction with... Figure 3The outer casing 110 is provided with an abutment protrusion 119. For example, the outer casing 110 has an abutment protrusion 119 protruding from its housing 111 within the first inner cavity 112. The abutment protrusion 119 is adapted to the strip-limiting portion 128 to restrict the extreme position of the inner component 120's rotation within the outer casing 110. For instance, the inner component 120 can rotate appropriately within the outer casing 110, but only within a certain range. This design helps prevent the cable 200 from being subjected to circumferential force and rotating after assembly, thus avoiding the inner component 120 rotating within the outer casing 110 and protecting the connector assembly 100 and the connected cable 200.

[0056] In some embodiments, a cable connector 400, such as Figure 17 As shown in the figure, for ease of understanding, the cable 200 connected to the cable connector 400 is illustrated. The cable connector 400 includes a socket 300 and a connector plug assembly 100 as described in any embodiment. The socket 300 is detachably plugged into the insertion end 102 of the connector plug assembly 100. In the plugged state, the socket 300 abuts against the inner sleeve 120 and the waterproof sealing ring 140, snaps into the outer shell 110, and applies pressure to the sealing sleeve 130. As an example, this protects the optical cable head, and the cable connector 400, divided into a socket part and a plug part, is easy to assemble and use. Exemplarily, the cable connector 400 can be used as an optical fiber protection connector, and can also be used in other cable connections. Those skilled in the art will understand that in practical applications, the socket 300 may also have a plugging structure that mates with the plug of the cable 200, which is not shown in the figure. It is understood that, since the cable connector 400 adopts the connector plug assembly 100 described in any embodiment, it also has the beneficial technical effects of the connector plug assembly 100, which will not be elaborated here.

[0058] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application.
