[0036] The following embodiments of the present application are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0037] See also Figure 1-Figure 5An embodiment of the present application provides a cable connector 100, comprising: a placement member 10, a connector 20, and a first shell 30. The placement member 10 comprises: an inner fitting surface 11 that is rotated along the central axis of the cable connector 100 to form a ring, an outer fitting surface 12 that faces away from the fitting surface, and an abutment portion 13 that is perpendicularly connected to the inner fitting surface 11. The connector 20 is fitted with the inner fitting surface 11, and the connector 20 is abutted with the abutment portion 13, and the connector 20 is sleeved inside the placement member 10. The first shell 30 is fitted with the outer fitting surface 12, and the first shell 30 is abutted with the placement member 10. The first shell 30 is sleeved on the end of the placement member 10 that faces away from the connector 20.

[0038] Specifically, the inner fitting surface 11 is in close contact with the outer surface of the connector 20, providing good support and stability. The inner fitting surface 11 is designed in a ring shape, which not only surrounds the cable but also allows the connector 20 to be stably fixed in the placement member 10, effectively reducing the movement or shaking of the connector 20 and ensuring the stability of signal transmission.

[0039] The outer fitting surface 12 is located on the side opposite to the inner fitting surface 11 and is tightly fitted with the first housing 30. The outer fitting surface 12 is also designed to be annular, so that the first housing 30 can be securely mounted on the outside of the placement member 10, thereby forming an overall stable structure and further improving the stability of the connector.

[0040] The abutment portion 13 is perpendicularly connected to the inner fitting surface 11, providing structural support. The abutment portion 13 is primarily used to abut the corresponding portions of the connector 20 and the first housing 30, ensuring a tight connection between the components and preventing displacement of the connector during use.

[0041] Through the inner and outer fitting surfaces 12 and the abutting portion 13 of the placement member 10 , the cable connector 100 can form a stable closed structure, effectively reducing the impact of the external environment on the connector, such as vibration or pulling.

[0042] Connector 20 fits snugly within placement member 10, closely fitting within inner contact surface 11 and secured to placement member 10 via abutment 13. Connector 20's primary function is to provide an electrical connection between the cable and the connector. The close fit between connector 20 and inner contact surface 11 ensures the cable is securely secured within connector 20, preventing it from shifting or falling out due to external forces during use.

[0043] The abutment with the abutment portion 13 further enhances the fixing effect of the connecting member 20 , thereby preventing the cable connector 100 from becoming loose or misaligned during long-term use.

[0044] The combination of the connecting member 20 and the placing member 10 makes the overall structure of the cable connector 100 more compact, reduces the displacement of the connecting member 20 due to external forces, and thus improves the stability of the electrical connection.

[0045] The first housing 30 covers the exterior of the placement member 10 and the connector 20, protecting the internal structure. By tightly fitting the outer mating surface 12, the first housing 30 prevents external factors such as dust and moisture from entering the connector, ensuring the long-term reliability of the connector. The first housing 30 abuts one end of the placement member 10, further stabilizing the placement member 10 and the connector 20 and preventing deformation or displacement of the cable connector 100 when subjected to external forces.

[0046] In one embodiment, a through hole 14 is defined within the placement member 10. The through hole 14 includes a first portion 141 and a second portion 142 connected to the first portion 141. One end of the connector 20 is located at the junction between the first portion 141 and the second portion 142. The connector 20 located at the second portion 142 is connected to the input cable, while the connector 20 located at the first portion 141 is connected to the output cable.

[0047] Specifically, first portion 141 is primarily used to connect the output cable. The size and shape of first portion 141 are adapted to the output cable, ensuring that the cable can be stably embedded therein, forming a secure connection. This portion also cooperates with connector 20 to further secure the cable, preventing it from moving or falling off during use.

[0048] Second portion 142 accommodates the connector 20. This portion matches the connector 20, allowing it to be stably embedded therein. This design provides support and fixation for the connector 20, preventing it from loosening within the placement member 10. It is primarily used for connecting the input cable. The size and shape of second portion 142 are adapted to the input cable, ensuring that the cable can be stably embedded therein, forming a secure connection. This portion also further secures the cable by cooperating with the connector 20, preventing it from moving or falling off during use.

[0049] Through the design of the first portion 141 and the second portion 142 , the through hole 14 provides a clear and stable path for cable connection, ensuring that the cable can be well supported and protected within the placement member 10 .

[0050] In one embodiment, the cable connector 100 includes a fixing assembly 40 and a protective assembly 50. The fixing assembly 40 is in contact with the inner contact surface 11 and the abutment portion 13. The fixing assembly 40 is sleeved within the placement member 10 and is located within the second portion 142. The protective assembly 50 is in contact with the fixing assembly 40 and the outer contact surface 12, and is connected to the first housing 30. The protective assembly 50 is encircled and in contact with the input cable.

[0051] Specifically, the fixing assembly 40 is a key component of the cable connector 100, primarily used to stabilize the connector 20 and support the cable. The fixing assembly 40 fits snugly against the inner fitting surface 11 of the placement member 10, ensuring it is securely embedded within the placement member 10. This snug fit provides effective support, preventing the fixing assembly 40 from shifting during use.

[0052] The other end of the fixing assembly 40 contacts the abutment portion 13 of the placement member 10. This structure further positions and supports the fixing assembly 40 within the placement member 10, ensuring the stability of the overall structure. The fixing assembly 40 is designed to be placed within the second portion 142 of the through-hole 14 within the placement member 10. This ensures that the fixing assembly 40 can tightly surround the connector 20 and provide initial securement of the cable, preventing unnecessary movement or wear of the cable within the connector.

[0053] The fixing assembly 40 provides a stable support structure for the cable connection by closely cooperating with the fitting surface 11 and the abutting portion 13 of the placement member 10, thereby preventing the connection from being unstable due to external factors.

[0054] The protection component 50 is designed to further enhance the protection function of the cable connector 100 and ensure the integrity and safety of the cable during use.

[0055] The protection component 50 fits tightly onto the outer surface of the fixing component 40 and the outer fitting surface 12 of the placement component 10. This double fitting ensures the stability of the protection component 50, enabling it to effectively protect the cable from the influence of the external environment.

[0056] The protective assembly 50 is also connected to the first housing 30 to form a complete protective structure. Through this connection, the protective assembly 50 not only enhances the structural strength of the overall connector, but also further seals the cable connection portion 421 to prevent dust, moisture or other contaminants from entering.

[0057] The protective assembly 50 is arranged around the input cable and fits tightly against the surface of the cable. This design effectively secures the cable and prevents it from being damaged by stretching or bending during use.

[0058] The protective component 50 provides comprehensive protection for the cable through its dual fitting design with the fixing component 40 and the outer fitting surface 12, as well as its connection with the first shell 30, ensuring that the cable connector 100 can maintain its functionality and stability in various complex environments.

[0059] In a specific embodiment, the fixing assembly 40 includes a second shell 41, the second shell 41 is in contact with the inner contact surface 11, the second shell 41 is in contact with the abutting portion 13, the second shell 41 is located in the second portion 142, and the connecting member 20 is in contact with the second shell 41.

[0060] Specifically, the second housing 41 fits tightly against the inner fitting surface 11 of the placement member 10. This design ensures that the second housing 41 is securely fixed within the placement member 10, preventing it from shifting or loosening during use. By fitting against the inner fitting surface 11, the second housing 41 provides a stable support base for the connector 20.

[0061] One end of the second housing 41 contacts the abutment portion 13 of the placement member 10. This structural design further enhances the stability of the second housing 41, ensuring that it remains firmly fixed within the placement member 10. The abutment portion 13 provides additional mechanical support through contact with the second housing 41, thereby reducing the risk of displacement of the connector 20 under external forces.

[0062] The second housing 41 is designed to be placed within the second portion 142 of the through-hole 14 of the placement member 10. This arrangement enables the second housing 41 to tightly surround the connector 20 and provide additional protection for the connector 20. Through this structure, the second housing 41 not only enhances the stability of the connector 20, but also provides additional physical protection for the connector 20 and the cable, preventing them from being damaged by external environmental factors.

[0063] One end of the connector 20 is designed to contact and be fixed with the inner surface of the second housing 41. This abutment structure ensures that the connector 20 obtains additional support force in the second housing 41, effectively preventing the connector 20 from loosening or shifting due to vibration or tension during use.

[0064] The second shell 41, through close cooperation with the inner fitting surface 11 and the abutment portion 13, not only provides a more stable support structure for the connector 20, but also adds a layer of protection to the overall design of the fixing assembly 40, thereby improving the overall reliability of the cable connection.

[0065] In one embodiment, the fixing assembly 40 further includes a fixing member 42, which is connected to the second housing 41 and is located at an end of the second housing 41 away from the connector 20. One surface of the fixing member 42 is in contact with the inner contact surface 11, and the other surface of the fixing member 42 is formed into a ring shape. The fixing member 42 is used to fix the input cable.

[0066] Specifically, the fixing member 42 is securely mounted within the connector by connecting to the second housing 41. Its connection is located at the end of the second housing 41 away from the connector 20, ensuring that the fixing member 42, supported by the second housing 41, effectively secures and protects the input cable. This connection structure not only enhances the structural strength of the entire fixing assembly 40 but also ensures that the input cable's fixed position is protected from external interference.

[0067] One side of the fixing member 42 fits tightly against the inner contact surface 11 of the placement member 10, providing additional support and securing force, preventing the fixing member 42 from shifting due to vibration or external forces during use. By fitting against the inner contact surface 11, the fixing member 42 gains more stable support within the placement member 10, thereby ensuring the stability of the entire connector structure.

[0068] The other side of the fixture 42 forms a ring to accommodate and secure the input cable. This ring-shaped design ensures the input cable is securely fixed within the connector, preventing it from loosening or shifting due to external tension or other stresses during use. This ring-shaped structure effectively distributes stress on the input cable, reducing single-point pressure concentration and thus extending the service life of the cable and connector.

[0069] In a specific embodiment, the fixing member 42 includes a connecting portion 421 , and the connecting portion 421 abuts against the connecting hole 411 defined in the second shell 41 .

[0070] Specifically, the connecting portion 421 is a portion of the fixing member 42 and is typically configured as a protruding or extending structure for mating with the connecting hole 411 on the second housing 41. The main function of the connecting portion 421 is to ensure that the fixing member 42 is securely fixed within the second housing 41 through physical contact with the connecting hole 411, thereby preventing it from shifting or loosening during use.

[0071] Connecting hole 411 is provided on the second housing 41 and is specifically designed to accommodate the connecting portion 421 of the fixing member 42. The position and size of the connecting hole 411 are precisely designed to ensure that the connecting portion 421 can be tightly inserted and abutted. This design not only strengthens the connection between the fixing member 42 and the second housing 41, but also provides additional stability through a physical locking mechanism, preventing the fixing member 42 from shifting when subjected to external stress.

[0072] The abutment between the connecting portion 421 and the connecting hole 411 forms a more secure connection between the fixing member 42 and the second housing 41. This enhanced connection not only increases the overall strength of the fixing assembly 40, but also effectively improves the tensile strength of the cable connector 100, ensuring that the cable remains firmly connected even when subjected to external forces, avoiding the risk of loosening or breaking.

[0073] In one embodiment, the protective assembly 50 includes a first protective cover 51 and a second protective cover 52. The first protective cover 51 is sleeved over the outer fitting surface 12 and is located at the end facing away from the first housing 30. The second protective cover 52 is connected to the first protective cover 51, and the fixing member 42 is sleeved within the second protective cover 52.

[0074] Specifically, the first protective cover 51 is designed to fit over the outer mating surface 12 of the placement member 10, located at the end away from the first housing 30. Its primary function is to protect the exterior structure of the cable connector 100, preventing physical damage and environmental factors such as moisture and dust from entering the connector interior. The design of the first protective cover 51 ensures that the cable connector 100 is not easily affected by external factors during installation and use, thereby extending its service life.

[0075] The second protective cover 52 connects to the first protective cover 51 and encloses the fixture 42. It further protects key components within the cable connector 100, particularly the fixture 42, from direct impact by external mechanical forces or damage due to environmental fluctuations. The second protective cover 52 provides an additional layer of protection for the fixture 42 and enhances the durability and stability of the overall connector structure.

[0076] By fitting the first protective cover 51 over the outer contact surface 12 of the placement member 10 and connecting the second protective cover 52 to the first protective cover 51, a comprehensive protective barrier is formed. This design not only strengthens the connector's exterior but also protects the internal components from direct exposure to external impacts, thus preventing damage. This sleeve structure plays a key role in the protective assembly 50, ensuring the long-term stable operation of the connector.

[0077] The input cable enters the second portion 142 through the through hole provided in the second protective cover 52 and is connected to the input terminal of the connector 20 to transmit electrical signals.

[0078] In a specific embodiment, the diameter of the second protective sheath 52 gradually decreases along the direction opposite to the input cable connection.

[0079] Specifically, the second protective sleeve 52 has a tapered structure, that is, its diameter gradually decreases from the end close to the connector in the direction opposite to the input cable connection direction, so as to fit the shape of the cable and provide stronger physical protection and sealing effect.

[0080] The tapered design allows the second protective cover 52 to tightly wrap around the cable, reducing the gap between the cable and the second protective cover 52, thereby effectively preventing moisture, dust, and other external contaminants from entering the connector. This sealing performance is crucial for the long-term use of the cable connector 100 in harsh environments, preventing damage to the electronic components within the connector and ensuring stable and reliable signal transmission.

[0081] The tapered structure mechanically helps reduce stress concentration when the cable is subjected to tension or bending. When the cable is subjected to tension or bending, the tapered sleeve better distributes the stress, reducing stress concentration at a single point and reducing the risk of cable breakage or fatigue. This design effectively extends the service life of the cable and connector, especially in applications frequently subjected to external forces.

[0082] In a specific embodiment, when viewed along the axial direction F1 of the cable connector 100 , the connector, the fixing assembly 40 , the placement member 10 and the first shell 30 are sequentially sleeved from the inside out.

[0083] Specifically, connector 20 is located in the innermost layer, making direct contact with the cable's conductors to establish an electrical connection. As a core component for signal transmission, connector 20 ensures a stable electrical connection between the input and output cables. Its location in the inner layer minimizes environmental interference and damage.

[0084] The fixing assembly 40 fits snugly around the exterior of the connector 20, contacting the inner mating surface 11 and abutment portion 13 of the placement member 10. The main function of the fixing assembly 40 is to secure and stabilize the connector 20 within the placement member 10, preventing it from moving or loosening due to external forces or vibration, thereby ensuring a reliable electrical connection.

[0085] The placement member 10 is sleeved onto the exterior of the fixing assembly 40, with its inner contact surface 11 contacting the fixing assembly 40 and its outer contact surface 12 contacting the first housing 30. The placement member 10, with its annular structure, provides a stable support frame for the connector 20 and the fixing assembly 40. It not only supports and protects the internal components but also, through its interaction with the external housing, ensures the stability and sealing of the overall structure.

[0086] The first housing 30 is the outermost layer, covering the exterior of the placement member 10. As the outer shell of the entire cable connector 100, the first housing 30 provides ultimate physical protection and sealing. It effectively prevents environmental damage (such as moisture and dust) from eroding internal components, while also further strengthening the structural integrity of the connector through its close fit with the placement member 10.

[0087] The sequential assembly from the inside out ensures that each component fits tightly together during assembly. With the inner connector 20 securing the cable connector and the outer shell protecting it, the entire cable connector 100 forms a cohesive, impact-resistant structure. This structural design excels in resisting external physical shock and stress, thereby enhancing the connector's long-term reliability.

[0088] In a specific embodiment, when viewed along the radial direction F2 of the cable connector 100 , the connector, the fixing assembly 40 , the protection assembly 50 , the placement member 10 and the first shell 30 are coaxially arranged.

[0089] Specifically, the coaxial arrangement ensures optimal alignment of each component within the cable connector 100, thereby improving the mechanical strength and electrical performance of the entire connector. This design effectively reduces stress concentration caused by component misalignment and enhances the impact resistance and durability of the connector.

[0090] The above is only an implementation method of the present application. It should be pointed out that for ordinary technicians in this field, improvements can be made without departing from the creative concept of the present application, but these all fall within the scope of protection of the present application.
