For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood by specific circumstances.

[0022] See also Figures 1 to 5 The coaxial mixed connector of the embodiment of the utility model includes: a tail cap connector 1, which has a coaxial tail cap 2, a coaxial shielding layer 3 and a pin assembly 4 built in, the pin assembly 4 is fixedly connected to the inside of the tail cap connector 1, the coaxial shielding layer 3 is fixedly arranged on the pin assembly 4, the coaxial shielding layer 3 is provided with a hole axis 31, the hole axis 31 is provided with a circle of support platform 32, the coaxial tail cap 2 is built in the coaxial shielding layer 3 and abuts against the support platform 32, the coaxial tail cap 2 is welded and connected to the coaxial shielding layer 3; a shell 5 connected to the tail cap connector 1, which has a jack assembly 6 built in; and a core 7, the core 7 is respectively arranged on the jack assembly 6 and the coaxial tail cap 2.

[0023] In the above embodiment, the tail cap connector 1 is used as the main structure, and the coaxial tail cap 2, the coaxial shielding layer 3 and the pin assembly 4 are built in. The coaxial shielding layer 3 is tightly combined with the coaxial tail cap 2 through its designed hole axis 31 and the support platform 32, and the firmness of the connection is ensured by welding. This connection method not only enhances the stability of the connection, but also improves the durability and reliability of the connector, and effectively prevents the problem of loose connection or breakage caused by factors such as vibration or impact. The signal is mainly transmitted through the ferrule 7 in the coaxial tail cap 2 in the coaxial mixed connector. The ferrule 7 serves as the main transmission channel for the signal. The coaxial shielding layer 3 plays a vital role. It can not only effectively prevent the influence of external interference on the signal and protect the stable transmission of the signal, but also prevent signal leakage and reduce the loss and attenuation of the signal during the transmission process. In addition, the shielding layer can also improve the quality of the signal, making the signal clearer and more accurate during the transmission process. The shell 5 is the external structure of the connector, which is connected to the tail cap connector 1 and has a jack assembly 6 built in. The jack assembly 6 matches the interface of the external device or cable, and the connection between the connector and the external device or cable is achieved through the close fit between the ferrule 7 and the jack assembly 6. The ferrule 7 is respectively arranged in the jack assembly 6 and the coaxial tail cap 2, and is connected to the external device or cable by inserting the jack assembly 6. This connection method not only facilitates users to quickly connect and disconnect operations, but also ensures the stability and reliability of the connection. In summary, the working principle of the coaxial mixed connector is to ensure the stable transmission of the signal and the reliability of the connector through the combined effects of multiple aspects such as the signal transmission of the center conductor, the protection of the coaxial shielding layer 3, the firmness of the welding connection, and the close fit between the jack assembly 6 and the ferrule 7. Its design fully considers the convenience and durability of use, and provides users with a high-quality connection experience.

[0024] Please refer to Figures 1 to 5 In another embodiment, the housing 5 includes an inner sleeve 51 and an outer sleeve 52 , the inner sleeve 51 is threadedly connected to the tail cap connector 1 , and the outer sleeve 52 is sleeved on the inner sleeve 51 .

[0025] In the above embodiment, the inner sleeve 51 is tightly connected to the tail cap connector 1 through threads. This connection method not only ensures the firmness of the connection, but also enables the connector to maintain structural stability when subjected to external forces. The threaded connection is self-locking, which can prevent the connector from loosening under vibration or impact, thereby ensuring the long-term reliable use of the connector. The outer sleeve 52 is sleeved on the inner sleeve 51, further enhancing the structural stability of the connector. The outer sleeve 52 can prevent the inner sleeve 51 from being directly impacted and worn by the external environment, and can also prevent the inner sleeve 51 from dimensional changes caused by temperature changes, thereby ensuring that the connector can maintain stable performance under various environmental conditions.

[0026] Please refer to Figures 1 to 5In another embodiment, the inner sleeve 51 is provided with a barb 511 and a protrusion 512 , and the outer sleeve 52 is provided with a hole groove 521 that fits with the barb 511 and the protrusion 512 .

[0027] In the above embodiment, when the inner sleeve 51 is assembled with the outer sleeve 52, the barb 511 and the protrusion 512 on the inner sleeve 51 will be embedded in the hole groove 521 of the outer sleeve 52. This embedding design not only enhances the connection strength between the inner and outer sleeves 52, but also makes it difficult for the inner and outer sleeves 52 to be relatively displaced or loosened when the connector is subjected to external force. This design greatly improves the overall stability of the connector, allowing it to maintain stable performance in various complex environments. In addition, the fit between the barb 511 and the protrusion 512 and the hole groove 521 also makes it easier to align and fix the connector during the assembly process, thereby improving the efficiency and accuracy of assembly.

[0028] Please refer to Figures 1 to 5 In another embodiment, a friction layer 522 is disposed on the outer side of the outer sleeve 52 .

[0029] In the above embodiment, the friction layer 522 provides better grip and anti-slip function. When installing or removing the connector, the user can hold the outer sleeve 52 more easily through the friction layer 522 to prevent the user from slipping or falling.

[0030] Please refer to Figures 1 to 5 In another embodiment, a sealing element is further included, and the sealing element is arranged between the tail cap connector 1 and the shell 5.

[0031] In the above embodiments, since the coaxial mixed connector often needs to be used in various environments, including humid, dusty or corrosive environments, the sealing element can effectively prevent moisture, dust or other contaminants from entering the interior of the connector. By keeping the interior of the connector clean and dry, the sealing element ensures the normal operation of the internal components of the connector, thereby improving the stability and reliability of the connector. Secondly, the sealing element also plays a role in shock absorption and buffering. When the connector is subjected to vibration, impact or other external forces, the sealing element can absorb part of the energy and reduce the stress and damage inside the connector. This shock absorption and buffering effect not only protects the components inside the connector, but also extends the service life of the connector. Finally, the sealing element also ensures the stability of the connector during the connection process. When the connector is connected to an external device or cable, the sealing element can ensure a close fit between the connector and the interface to prevent signal loss or interference caused by looseness or excessive gaps. This stability not only ensures the transmission quality of the signal, but also improves the reliability of the connector.

[0032] Please refer to Figures 1 to 5In another embodiment, the pin assembly 4 includes a conductive pin 41 and an insulating spacer 42 , and the conductive pins 41 are isolated from each other by the insulating spacer 42 and fixed in the tail cap connector 1 .

[0033] In the above embodiment, the insulating spacer 42 plays a vital role in the pin assembly 4. It is located between the conductive pins 41, isolating the conductive pins 41 from each other, and preventing interference and short circuit between signals. The insulating spacer 42 is usually made of a material with good insulation performance, such as plastic or rubber, to ensure that it can effectively isolate the conductive pins 41. Through the isolation effect of the insulating spacer 42, the conductive pins 41 are stably fixed in the tail cap connector 1 and maintain a certain distance between each other. This design not only ensures the stable transmission of signals, but also improves the reliability and safety of the connector.

[0034] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with the profession can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention.
