Detailed implementation manners

[0055] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0056] Before further detailed description of the embodiments of the present invention, the orientation terms involved in the embodiments of the present invention, such as "upper part", "lower part", and "side part", do not have the meaning of limiting the protection scope of the present invention.

[0057] To make the technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0058] Figure 1 A schematic diagram of a three-core coaxial conductor assembly according to an embodiment of the present invention; Figure 2 An exploded schematic diagram of a three-core coaxial conductor assembly according to an embodiment of the present invention.

[0059] As Figure 1 and Figure 2 shown, an embodiment of the present invention provides a three-core coaxial conductor assembly 100, and the three-core coaxial conductor assembly 100 includes:

[0060] Conductor body 110;

[0061] A connector, including a socket connector 120 and a pin connector 130 which are connected to each other. One end of the socket connector 120 away from the pin connector 130 is fixedly connected to the conductor body 110, and one end of the pin connector 130 away from the socket connector 120 is connected to a cable.

[0062] A protective shell 140. A plurality of conductor bodies 110 are arranged in the protective shell 140. The plurality of conductor bodies 110 are arranged in a staggered manner and are evenly arranged in the protective shell 140.

[0063] Among them, the three-core coaxial conductor assembly 100 includes a protective shell 140 and a plurality of conductor bodies 110 arranged in the protective shell 140. The plurality of conductor bodies 110 are evenly distributed in the protective shell 140. Transmission signals are simultaneously transmitted through the plurality of conductor bodies 110, improving the efficiency of electrical connection and signal transmission, thereby improving work efficiency and user experience. At the same time, the connection between the conductor body 110 and other cables is realized through the connector. The connector includes a socket connector 120 and a pin connector 130. The socket connector 120 and the pin connector 130 are plugged and connected. One end of the socket connector 120 facing away from the pin connector 130 is connected to the conductor body 110, and one end of the pin connector 130 away from the socket connector 120 is connected to a cable, which can improve the sealing effect of the connector, prevent liquid and moisture from entering the three-core coaxial conductor assembly 100, and improve the transmission stability and use safety of the three-core coaxial conductor assembly 100.

[0064] Specifically, the three-core coaxial conductor assembly 100 of the present application uses three conductor bodies 110 placed in the protective shell 140 to achieve good electrical connection and signal transmission, improving work efficiency. If two conductor bodies 110 are used, the transmission efficiency can also be improved, but the remaining space in the protective shell 140 will be relatively large, and the space in the protective shell 140 is not effectively utilized, resulting in space waste. If four or more conductor bodies 110 are used, a protective shell 140 with a correspondingly larger diameter is required, which also limits the use space of the conductor assembly 100. Therefore, the present application uses three conductor bodies 110 placed in the protective shell 140. On the one hand, it can make full and reasonable use of the space in the protective shell 140, and on the other hand, it can avoid the diameter of the protective shell 140 being too large, affecting the space occupied during the subsequent installation of the conductor assembly 100.

[0065] Exemplarily, the three conductor bodies 110 in this embodiment are arranged in a circle within the protective shell 140. The connecting lines of the centers of the three conductor bodies 110 form a circle with a diameter of 12 mm. This can ensure that the three conductor bodies 110 are reasonably arranged within the protective shell 140. At the same time, the connectors are located at the ends of the conductor bodies 110. The connecting lines of the centers of the three connectors form a circle with a diameter of 25 nm. Since the three conductor bodies 110 are evenly arranged within the protective shell 140, the connecting line between the center of the protective shell 140 and the center of the conductor body 110 is set as the connection line, and the included angle between adjacent two connection lines is 120°.

[0066] It should be noted that the height difference between multiple conductor bodies 110 is 100 mm to 150 mm. That is to say, the height difference between the three conductor bodies 110 is 100 mm to 150 mm. This can avoid interference and collision between adjacent connectors and ensure the stability and reliability of signal transmission of the conductor assembly 100.

[0067] It can be understood that the material of the protective shell 140 is stainless steel. The three conductor bodies 110 are accommodated together by the protective shell 140, which is convenient for the three conductor bodies 110 to be used together and transmit signals together, thereby improving the signal transmission efficiency. The stainless steel protective shell 140 can extend the service life of the three-core coaxial conductor assembly 100.

[0068] Exemplarily, usually the protective shell 140 protects the three conductor bodies 110 by avoiding the connector positions. Since the conductor body 110 is a semi-rigid conductor and is not easily bent, after installing the connector, it is necessary to avoid the situation that the protective shell 140 covers the connector and causes the connector and the conductor body 110 to be in a stressed state, so as to ensure the service life of the conductor body 110 and the connector.

[0069] Figure 3 Schematic diagram of a conductor body according to an embodiment of the present invention; Figure 4 Exploded schematic diagram of a conductor body according to an embodiment of the present invention.

[0070] In a feasible implementation manner, as Figure 2 and Figure 3 shown, the conductor body 110 includes:

[0071] A wire core 111;

[0072] An insulating dielectric layer 112, which is externally provided on the wire core 111. The insulating dielectric layer 112 includes a plurality of interconnected insulating particles 1121;

[0073] A shielding tube 113, which is externally provided on the insulating dielectric layer 112;

[0074] The insulating sheath 114 is externally provided on the shielding tube 113.

[0075] Among them, the conductor body 110 is a semi-rigid coaxial conductor, and the conductor body 110 includes a wire core 111, an insulating dielectric layer 112, a shielding tube 113, and an insulating sheath 114 that are sleeved in sequence.

[0076] Exemplarily, in this embodiment, the wire core 111 is made of copper, the shielding tube 113 is made of a copper cylindrical pipe material, and the insulating dielectric layer 112 and the insulating sheath 114 are made of polyether ether ketone material, polysulfone material, and / or polyimide material.

[0077] It should be noted that copper has excellent electrical conductivity. Its conductivity is second only to silver (with a lower price than silver) among metals, far higher than aluminum and other metal materials. That is to say, the copper wire core 111 can carry a larger current with a smaller cross-sectional area, thereby reducing energy loss; copper also has the effects of low resistivity and small voltage loss, and can maintain a high voltage quality during power transmission to ensure stable power supply; at the same time, copper also has good heat dissipation, corrosion resistance, relatively high strength, and fatigue resistance, which can improve the quality and service life of the conductor body. Copper as the shielding tube 113 can effectively isolate the electromagnetic field and prevent electromagnetic interference from affecting other electronic devices or systems; at the same time, the electrical conductivity of copper can absorb or reflect electromagnetic waves to maintain the integrity of the signal, thereby improving the anti-interference ability of the conductor body 110. The insulating dielectric layer 112 is adjacent to the wire core 111, which can prevent current leakage and ensure that the current can be efficiently transmitted through the wire core 111. The insulating dielectric layer 112 has good electrical insulation and heat resistance, which can ensure the safety of the conductor body 110 during use. The insulating sheath 114 is wrapped outside to play a protective role, which can prevent the conductor body 110 from being affected by external factors such as mechanical damage and chemical corrosion, thereby extending the service life of the conductor body 110, and at the same time can also improve the wear resistance of the conductor body 110.

[0078] Specifically, the insulating dielectric layer 112 and the insulating sheath 114 are made of polyether ether ketone, polysulfone, and / or polyimide. Polyether ether ketone (PEEK) has excellent insulation performance and can maintain stable electrical performance under high voltage and high-frequency environments. Its dielectric properties are excellent below 260°C, and it can resist irradiation by energy rays; PEEK maintains good insulation performance under high-dose irradiation; at the same time, PEEK also has the characteristics of high temperature resistance, high strength, corrosion resistance, and flame retardancy. Polysulfone (PSF) has excellent mechanical properties, including high rigidity, wear resistance, and high strength, and can maintain excellent mechanical properties even at high temperatures. Its service temperature range is from -100°C to 150°C, the long-term use temperature is 160°C, and the short-term use temperature is 190°C. At the same time, it has characteristics such as high thermal stability, hydrolysis resistance, good dimensional stability, small molding shrinkage rate, non-toxicity, radiation resistance, flame resistance, and self-extinguishing properties. Polyimide (PI) has excellent insulation performance and radiation resistance. Polyimide has excellent electrical properties and heat resistance within the range of 200°C to 400°C. It is a type of insulating material with excellent comprehensive performance. The high dielectric strength of polyimide enables it to effectively insulate electrical components and prevent current flow; at the same time, polyimide can maintain stable performance in a radiation environment. In this embodiment, the insulating dielectric layer 112 and the insulating sheath 114 are made of polyether ether ketone material.

[0079] In a feasible implementation manner, the insulating particles 1121 include a large cylindrical section and a small cylindrical section that are connected to each other. The small cylindrical section is provided with a first central hole, the diameter of the first central hole matches the outer diameter of the wire core 111, the large cylindrical section is provided with a second central hole, the diameter of the second central hole matches the outer diameter of the small cylindrical section, and the axes of the first central hole and the second central hole coincide;

[0080] Wherein, when two adjacent insulating particles 1121 are connected, the small cylindrical section is inserted into the second central hole.

[0081] It should be noted that in this example, the insulating dielectric layer 112 is made into a plurality of insulating particles 1121 that can be plugged into each other. In this way, when the insulating dielectric layer 112 is sleeved on the wire core 111, it can meet the requirements of different lengths of the three conductor bodies 110, avoiding temporary cutting. On the one hand, it improves the production efficiency of the conductor body 110, and on the other hand, it can avoid waste of materials, thereby reducing production costs.

[0082] Specifically, the insulating particles 1121 include a large cylindrical section and a small cylindrical section. The small cylindrical section can be inserted into the large cylindrical section of another insulating particle to ensure the stability and reliability of the connection between two adjacent insulating particles 1121. At the same time, the large cylindrical section and the small cylindrical section are sleeved together on the outside of the wire core 111, and the wire core 111 is located at the central position of the large cylindrical section and the small cylindrical section to ensure the uniformity of the insulating dielectric layer 112 on the wire core 111 and ensure the stability and balance of insulation and radiation resistance.

[0083] Figure 5 is an exploded schematic diagram of a jack connector according to an embodiment of the present invention; Figure 6 Schematic cross-sectional view of a jack connector according to an embodiment of the present invention.

[0084] In a possible implementation, Figure 5 and Figure 6 As shown, the jack connector 120 includes:

[0085] A first housing 121, wherein a first hole section 1211, a second hole section 1212, a third hole section 1213 and a stepped hole section 1214 are sequentially disposed in the first housing 121;

[0086] The first insulator 122 is disposed in the first housing 121 , and the first insulator 122 is located in the first hole section 1211 , the second hole section 1212 , and the third hole section 1213 ;

[0087] The second insulator 123 is in contact with the first insulator 122 and is located in the third hole section 1213. A plug hole 124 is provided at the center of the first insulator 122 and the second insulator 123.

[0088] A large shaft sleeve 125, at least a portion of the large shaft sleeve 125 is disposed in the stepped hole section 1214, and the large shaft sleeve 125 abuts against a side of the second insulator 123 facing away from the first insulator 121;

[0089] A small shaft sleeve 126, at least a portion of the small shaft sleeve 126 is disposed in the large shaft sleeve 125;

[0090] The wire clamp 127 is disposed in the large shaft sleeve 125 . The small shaft sleeve 126 abuts against the wire clamp 127 . The wire clamp 127 is configured to clamp the conductor body 110 .

[0091] Among them, one side of the wire clip 127 of the jack connector 120 is covered on the conductor body 110, and one side of the first shell 121 of the jack connector 120 is plugged with the pin connector 130, and the end of the pin connector 130 away from the jack connector 120 is connected to other flexible coaxial cables to achieve signal transmission. It can be understood that when the conductor body 110 is not working, the jack connector 120 and the pin connector 130 are separated, and at this time, the end of the jack connector 130 away from the conductor body 110 is closed by the first cap to prevent dust and debris from entering the jack 124 and affecting the subsequent connection between the jack connector 120 and the pin connector 130; similarly, at this time, the end of the pin connector 130 away from other flexible coaxial cables is closed by the second cap to ensure the reliability and stability of subsequent use.

[0092] It should be noted that the jack connector 120 also includes:

[0093] The first sealing ring 128 is arranged between the large shaft sleeve 125 and the first housing 121, and the first sealing ring 128 is located at one end close to the second insulator 123.

[0094] Specifically, the first sealing ring 128 and the wire clamp 127 are the tails of the socket connector 120. After inserting the conductor body 110 into the wire clamp 127, the large shaft sleeve 125 is threadedly connected to the first housing 121. By rotating the large shaft sleeve 125 to squeeze the first sealing ring 128, it can prevent liquid and moisture from invading the inside of the socket connector 120 between the first housing 121 and the large shaft sleeve 125 of the socket connector 120. The small shaft sleeve 126 is threadedly connected to the large shaft sleeve 125. By tightening the small shaft sleeve 126, the small shaft sleeve 126 moves towards the wire clamp 127 direction, and then squeezes and compresses the wire clamp 127. Since the material of the wire clamp 127 is red copper and the surface of the wire clamp is silver-plated, it has certain ductility. After being compressed and extruded, it generates plastic deformation, and then can hoop the insulating sheath 114 of the conductor body 110, which can prevent liquid and moisture from entering the inside of the socket connector 120 between the small shaft sleeve 126 and the insulating sheath 114, ensure the sealing performance of the socket connector 120, and improve the reliability and stability of the transmission of the conductor assembly 100. It can be understood that the conductor body 110 is inserted into the socket 124 of the socket connector 120 to improve the reliability and stability of the data transmission of the conductor body 110.

[0095] It should be noted that the socket 124 is in the shape of a hollow shell and is inserted into the first insulator 122 and the second insulator 123. The first insulator 122 and the second insulator 123 can separate and insulate the socket 124 from the first housing 121, avoiding the conduction between the socket 124 and the first housing 124 from affecting the signal transmission of the conductor body 110. The materials of the first insulator 122 and the second insulator 123 are polyether ether ketone. Polyether ether ketone has excellent high-temperature resistance and radiation resistance performance, which can ensure the normal use of the socket connector 120 in high-temperature and radiation environments, expand the application range of the conductor assembly 100, and at the same time improve the service life of the conductor assembly 100.

[0096] It can be understood that the outer surface of the first housing 121 is a milled hexagon, which is convenient for the installation and tightening operation of the connector in a narrow space, and avoids the interference with other conductors when tightening with a torque wrench.

[0099] A nut 1301;

[0100] A first bushing 1302 disposed within the nut 1302. A first step 1321 is provided on the outside of the first bushing 1302. An insertion joint seam 1322 is formed between the first bushing 1302 and the nut 1301, and the first housing 121 is inserted into the insertion joint seam 1322;

[0101] A third insulator 1303 located within the first bushing 1302 and at least partially outside the nut 1301. A pin 1308 is provided at the center of the third insulator 1303, and the pin 1308 is in plug-in mating with the jack 124;

[0102] A second housing 1304, at least part of which is located within the nut 1301. The second housing 1304 abuts against the first bushing 1302. A fourth hole section 1341 and a fifth hole section 1342 are provided within the second housing 1304, and the third insulator 1303 is located within the fourth hole section 1341;

[0103] A second bushing 1305 disposed within the fifth hole section 1342 and close to the third insulator 1303;

[0104] A connecting bushing 1306 disposed within the fifth hole section 1342, at least part of the connecting bushing 1306 being outside the second housing 1304. A washer 1307 is provided between the connecting bushing 1306 and the second bushing 1305.

[0105] Similarly, the washer 1307 and the connecting bushing 1306 of the pin connector 130 are sleeved on other flexible coaxial cables. The nut 1301 end of the pin connector 130 is plugged into the jack connector 120, and the end of the jack connector 120 away from the pin connector 130 is connected to the conductor body 110 to achieve signal transmission.

[0106] Among them, the pin connector 130 further includes:

[0107] A second sealing ring 1309 disposed within the nut 1301 and located on the first step 1321;

[0108] A third sealing ring 1310 disposed between the connecting bushing 1306 and the washer 1307;

[0109] Among them, when the pin connector 130 is connected to the jack connector 120, the first housing 121 abuts against the second sealing ring 1309.

[0110] Specifically, an insertion joint seam 1322 is formed between the first bushing 1302 and the nut 1301. Then, the first outer shell 121 of the jack connector 120 is inserted into the insertion joint seam 1322. After the jack 124 of the jack connector 120 is connected to the pin 1308 of the pin connector 130, the first outer shell 121 presses the second sealing ring 1309, thereby achieving a tight combination of the jack connector 120 and the pin connector 130, and preventing liquid and moisture from entering the connector interior from the connection between the jack connector 120 and the pin connector 130, which affects the transmission efficiency and transmission stability of the signal transmission of the conductor assembly 100. The third sealing ring 1310 is arranged at the tail of the pin connector 130. The connecting bushing 1306 is threadedly connected to the second outer shell 1304. By tightening the connecting bushing 1306, the third sealing ring 1310 and the washer 1307 are compressed. On the one hand, other flexible coaxial cables are clamped, and on the other hand, it can prevent liquid and moisture from entering the interior of the pin connector 130 from between the connecting bushing 1306 and the second outer shell 1304. It can be understood that at least a part of other cables needs to enter the interior of the pin 1308. After the pin 1308 and the jack 124 are connected, the conduction between the conductor body 110 and other cables is ensured, thereby realizing the reliability and stability of signal transmission.

[0111] It should be noted that the third insulator 1303 can separate and insulate the pin 1308 and the second outer shell 1304, preventing the pin 1308 and the second outer shell 1304 from conducting and affecting the signal transmission of the conductor body 110. The material of the third insulator 1303 is polyether ether ketone, and polyether ether ketone has excellent high-temperature resistance and radiation resistance performance, which can ensure the normal use of the pin connector 130 in high-temperature and radiation environments, expand the applicable range of the conductor assembly 100, and at the same time improve the service life of the conductor assembly 100.

[0112] It should be noted that the materials of the first bushing 1302 and the second bushing 1305 are brass, which can play a role in assisting conduction and supporting the internal structure, and improve the stability of the pin connector 130.

[0113] In a feasible implementation manner, a first annular groove is provided on one side of the nut 1301 facing the second outer shell 1304, and a second annular groove is provided on one side of the second outer shell 1304 facing the nut 1301. The pin connector 130 further includes:

[0114] A snap ring 1311, part of the snap ring 1311 is snap-fitted into the second annular groove, and part of the snap ring 1311 is snap-fitted into the first annular groove.

[0115] Among them, the fixing connection between the second housing 1304 and the nut 1301 is realized through the snap ring 1311. While realizing the connection between the second housing 1304 and the nut 1301, the rotation of the nut 1304 and the second housing 1304 can also be realized. When the fixing connection between the pin connector 130 and the jack connector 120 is realized by rotating the nut 1301 in this way, the stability of the second housing 1304 can be ensured, and it can be avoided that other cables and the conductor body 110 rotate along with it, causing self-twisting of other cables and the conductor body 110, which affects the use safety and service life of other cables and the conductor body 110.

[0116] In summary, the insulating parts of the present application all adopt polyetheretherketone materials. While ensuring the insulation performance, the three-core coaxial conductor assembly 100 can also be used in high-temperature and irradiated environments, improving the applicable range and service life of the conductor assembly 100. Through the matching connection between the conductor body 110 and the connector, the structure is simple, suitable for mass production, improving production efficiency and reducing production costs.
