Abstract
Description
Technical Field
[0001] This application relates to the technical field of cable connectors, and in particular, to a coaxial cable connector assembly and a coaxial cable combination. Background Art
[0002] Radio frequency coaxial cables are mainly used in applications in the high-frequency range, such as in environments like wireless communication, radio frequency measurement, satellite communication, and radar. Radio frequency coaxial cables can provide higher signal quality and lower signal loss. A radio frequency coaxial cable typically includes an inner conductor and an outer conductor. An insulating support structure is provided between the outer conductor and the inner conductor, and an insulating sheath is provided on the outer side of the outer conductor.
[0003] With the continuous improvement of signal transmission requirements, the transmission power of radio frequency coaxial cables is also increasing. For high-power radio frequency coaxial cables, a large amount of heat is generated during operation. At the same time, as the power of the signal source increases, the generated heat also increases sharply. When the radio frequency coaxial cable is in a high-power operating state, the heat generated by the inner conductor is much greater than that of the outer conductor, the temperature of the inner conductor is higher than that of the outer conductor, and the degree of thermal expansion of the inner conductor is more significant than that of the outer conductor. The inner conductor is more likely to arch inside the cable. Even more seriously, a short circuit may occur between the inner conductor and the outer conductor inside the cable, causing the high-power radio frequency cable to malfunction.
[0004] In response to the above heat dissipation problem, some improvements have also been proposed in the prior art. For example, Chinese Patent Publication No. CN221327425U discloses a water-cooled coaxial cable on July 12, 2024. The outer layer of this coaxial cable includes a first transmission line, outer conductive tubes symmetrically located at both ends of the first transmission line, and an outer insulating and waterproof sleeve. The inner layer of this coaxial cable includes a second transmission line, a first inner conductive tube, and a second inner conductive tube. The intermediate layer includes an insulating fixed head and an inner and outer waterproof isolation layer. The first transmission line is electrically connected to the outer conductive tube, and the outer insulating and waterproof sleeve is sleeved on the first transmission line and the outer conductive tube. The second transmission line is electrically connected to the first inner conductive tube and the second inner conductive tube in sequence. The insulating fixed head is sleeved and fixed between the second inner conductive tube and the outer conductive tube. A first water inlet pipe and a first water outlet pipe are respectively provided on the second inner conductive tube. Second water inlet pipes and second water outlet pipes are respectively provided at both ends of the channel formed between the outer layer and the intermediate layer. The utility model reduces inductance, improves the cooling effect, reduces equipment power loss, and increases the transmission distance. However, after carefully studying this technical document, it can be found that in order to achieve the effect of water-cooling and temperature reduction, the coaxial cable has also been correspondingly modified in this technical solution. This technical solution cannot be applied to general-form radio frequency coaxial cables in the prior art, and has important defects such as high implementation costs and poor implementation flexibility.

Detailed implementation manners
[0043] In order to enable those skilled in the art to better understand the solution of the present application, the technical solutions in the specific implementation manners of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the implementation manners of the present application. In the description of the present application, if a part has a central axis or a hollow chamber, the "inner side" of the part refers to the side of the part close to the central axis of the part or the side disposed inside the hollow chamber; the "outer side" of the part refers to the side of the part far from the central axis of the part. It should be noted that for the present application, the setting of the inner conductor and the outer conductor in the coaxial cable and the first fluid channel and the second fluid channel formed thereby are the most important technical features. In the following text, only the inner conductor, the outer conductor and other components in the coaxial cable are basically described. Other structures in the coaxial cable, such as the support structure between the inner conductor and the outer conductor, the insulation structure outside the outer conductor and other possible conductor structures, etc., are not very closely related to the implementation manners explained below. Therefore, in the following description, related other structures are omitted or only briefly introduced. It should be understood that the coaxial cable involved in the present application includes not only the inner conductor, the outer conductor, the first fluid channel and the second fluid channel mentioned below, but also other structures and components that are reasonable in the field of coaxial cables or are well - known to those of ordinary skill in the art and not mentioned.
[0044] The implementation manners of the present application provide a kind of as Figure 1The coaxial cable connector assembly 100 shown is used to connect to both ends of a coaxial cable 200 as shown in Figure 2 and can form a coaxial cable combination 300 as shown in Figure 3 so that the coaxial cable 200 can be interconnected with external devices (external devices refer to devices other than the coaxial cable combination 300, including but not limited to signal sources and antennas, etc., the same below). As shown in Figure 2 , the interior of the coaxial cable 200 includes an inner conductor 21 and an outer conductor 22. The inner conductor 21 is a hollow structure, and a first fluid channel 23 is formed in the inner conductor 21. The outer conductor 22 is also a hollow structure and is coaxially arranged with the inner conductor 21. A second fluid channel 24 is formed between the outer conductor 22 and the inner conductor 21.
[0045] As shown in Figure 1 , Figure 2 and Figure 3 , the coaxial cable connector assembly 100 includes a first connection mechanism 11 and a second connection mechanism 12. The first connection mechanism 11 is used to connect to one end of the coaxial cable 200, and the second connection mechanism 12 is used to connect to the other end of the coaxial cable 200.
[0046] As shown in Figure 4As shown, the first connection mechanism 11 extends substantially along the direction of the first straight line 101. A first chamber 111 is formed inside the first connection mechanism 11, and the first chamber 111 also extends substantially along the direction of the first straight line 101. Inside the first connection structure, the first chamber 111 is further divided into a first inlet chamber 1111 and a first outlet chamber 1112 that are isolated and not connected to each other. Injection holes 112 and discharge holes 113 are also formed on the side wall of the first connection mechanism 11. The injection holes 112 communicate with the first inlet chamber 1111. After the injection holes 112 and the first inlet chamber 1111 are connected, corresponding fluid can be injected into the first connection mechanism 11 through the injection holes 112. The discharge holes 113 communicate with the first outlet chamber 1112. After the discharge holes 113 and the first outlet chamber 1112 are connected, corresponding fluid can be discharged from the first connection mechanism 11 through the discharge holes 113. Further, the injection holes 112 can extend along a direction perpendicular to the first straight line 101, and the discharge holes 113 can also extend along a direction perpendicular to the first straight line 101. A first tubular channel 114 is also formed inside the first connection mechanism 11. The first tubular channel 114 is located in the first chamber 111. One end of the first tubular channel 114 is located in the first inlet chamber 1111, and the other end of the first tubular channel 114 is located in the first outlet chamber 1112. One end of the first tubular channel 114 is used to connect to the first fluid channel 23 in the coaxial cable 200. Only from the perspective of the first connection mechanism 11, the first tubular channel 114 can connect the first inlet chamber 1111 and the first outlet chamber 1112. However, when the first connection mechanism 11 is connected to the coaxial cable 200, the first tubular channel 114 is connected to the first fluid channel 23. At this time, the first tubular channel 114 cannot connect the first inlet chamber 1111 and the first outlet chamber 1112 to each other, and the first inlet chamber 1111 and the first outlet chamber 1112 are completely separated from each other. A first through hole 115 is provided at the other end of the first tubular channel 114. The first through hole 115 extends substantially along a direction perpendicular to the first straight line 101. The first through hole 115 communicates with the first inlet chamber 1111, and the first through hole 115 can connect the first tubular channel 114 and the first inlet chamber 1111. After the first connection mechanism 11 is connected to the coaxial cable 200, the first outlet chamber 1112 is connected and communicated with the second fluid channel 24.
[0047] As Figure 5As shown, the second connecting mechanism 12 extends substantially along the direction of the second straight line 102. A second chamber 121 is formed inside the second connecting mechanism 12, and the second chamber 121 also extends substantially along the direction of the second straight line 102. A second tubular channel 122 is further formed inside the second connecting mechanism 12. The second tubular channel 122 is located in the second chamber 121. One end of the second tubular channel 122 is used to connect to the first fluid channel 23 in the coaxial cable 200. The other end of the second tubular channel 122 is provided with a second through hole 123. The second through hole 123 extends substantially perpendicular to the second straight line 102. The second through hole 123 communicates with the second chamber 121, and the second through hole 123 can connect the second tubular channel 122 and the second chamber 121. After the second connecting mechanism 12 is connected to the coaxial cable 200, the second tubular channel 122 is connected and communicated with the first fluid channel 23, and the part of the second chamber 121 other than the second tubular channel 122 is connected and communicated with the second fluid channel 24. The second chamber 121 is a completely connected chamber. Although some structures and components are provided in the second chamber 121, the through holes provided in these structures and components that can communicate both sides do not divide the second chamber 121 into several completely isolated parts.
[0048] Under the above structural settings, when the first connecting mechanism 11 is connected to one end of the coaxial cable 200 and the second connecting mechanism 12 is connected to the other end of the coaxial cable 200, the injection hole 112, the first inlet chamber 1111, the first through hole 115, the first tubular channel 114, the first fluid channel 23, the second tubular channel 122, the second through hole 123, the second chamber 121, the second fluid channel 24, the first outlet chamber 1112 and the discharge hole 113 are sequentially connected to form a flow channel through which fluid can flow. At the same time, since the ends of the first connecting mechanism 11 and the second connecting mechanism 12 away from the coaxial cable 200 need to be connected to external devices, the above flow channel can form a closed channel that communicates with the outside only through the injection hole 112 and the discharge hole 113 during use. Fluid can enter through the injection hole 112 and flow in the closed flow channel and then be discharged through the discharge hole 113, realizing the flow and circulation of the fluid in the flow channel. In the present application, the above flow channel formed by the connection of the coaxial cable connector assembly 100 and the coaxial cable 200 can provide a channel for fluid flow and circulation without affecting the normal operation of the coaxial cable 200. To solve the problems such as poor heat dissipation performance and heat accumulation during the operation of the coaxial cable 200, fluids that are conducive to heat dissipation such as air can be injected into the flow channel, so that the temperatures at various parts inside the coaxial cable 200 tend to be the same, reducing the temperature difference at various parts inside the coaxial cable 200. At the same time, the heat inside the coaxial cable 200 can be carried out through the circulation of the fluid, slowing down or even completely solving the problem of heat accumulation inside the coaxial cable 200, improving the heat dissipation performance and heat dissipation effect during the operation of the coaxial cable 200, and further solving problems such as cable internal arching and short circuit caused by uneven heat, heat accumulation and poor heat dissipation efficiency. In practical applications, the fluid used for heat dissipation can be ordinary air, or other gases or liquids that can achieve heat dissipation effects and will not cause corrosion and damage to the coaxial cable 200. In the present application, the overall structures of the first connecting mechanism 11 and the second connecting mechanism 12 are basically similar. To adapt to different functions provided at both ends of the coaxial cable 200, there are some differences between the first connecting mechanism 11 and the second connecting mechanism 12 in some partial structures such as the injection hole 112, the discharge hole 113, the first chamber 111 and the second chamber 121.
[0049] As an alternative embodiment, as Figure 6As shown, the first connection mechanism 11 includes a first housing assembly 116 and a first connector 117. The first housing assembly 116 encloses a first chamber 111. An injection hole 112 and a discharge hole 113 are formed through the side wall of the first housing assembly 116. The first connector 117 is disposed within the first chamber 111. The first housing assembly 116 constitutes the main structure of the first connection mechanism 11, and other structures of the first connection mechanism 11 are disposed on or within the first housing assembly 116. The first housing assembly 116 encloses the aforementioned first chamber 111, and the injection hole 112 and the discharge hole 113 penetrate through the side wall of the first housing assembly 116, enabling the first chamber 111 to communicate with the outside. The first connector 117 is connected to the inner wall of the first housing assembly 116, and a first tubular channel 114 is formed inside the first connector 117. At the same time, the connection structure between the first connector 117 and the first housing assembly 116 divides the first chamber 111 into a first inlet chamber 1111 and a first outlet chamber 1112. The injection hole 112 communicates with the first inlet chamber 1111, and corresponding fluid can be input into the first inlet chamber 1111 through the injection hole 112. The discharge hole 113 communicates with the first outlet chamber 1112, and the corresponding fluid in the first outlet chamber 1112 can be discharged through the discharge hole 113. When the first connection mechanism 11 is connected to the coaxial cable 200, the first inlet chamber 1111 and the first outlet chamber 1112 are completely isolated.
[0050] As Figure 7As shown, the second connection mechanism 12 includes a second housing assembly 124 and a second connector 125. The second housing assembly 124 encloses the second chamber 121, and the second connector 125 is disposed within the second chamber 121. The second housing assembly 124 constitutes the main structure of the second connection mechanism 12, and other structures of the second connection mechanism 12 are disposed on or within the second housing assembly 124. The second housing assembly 124 encloses to form the aforementioned second chamber 121, the second connector 125 is disposed within the second chamber 121, and a second tubular channel 122 is formed inside the second connector 125. The function of the second chamber 121 is not only to form a space for accommodating the second connector 125 and allowing fluid to flow through, but also, when the second connection mechanism 12 is connected to the coaxial cable 200, the second chamber 121 also serves to connect the first fluid channel 23 and the second fluid channel 24 of the coaxial cable 200, enabling the fluid to flow from the first fluid channel 23 to the second fluid channel 24, so that the fluid can flow smoothly throughout the coaxial cable 200. In the second connection mechanism 12, although the second connector 125 is disposed within the second chamber 121 and fixed to the inner wall of the second chamber 121, the second connector 125 does not divide the second chamber 121 into two completely isolated small spaces. The entire second chamber 121 remains intact and connected, and each part in the second chamber 121 is interconnected and communicated, and the fluid can flow between various parts of the second chamber 121.
[0051] As an alternative embodiment, as Figure 8 and Figure 9As shown, the first connector 117 includes a first body member 1171 and a first connecting member 1172. The first body member 1171 is used to connect to the first fluid passage 23. One end of the first body member 1171 is used to be interconnected with the inner conductor 21 of the coaxial cable 200, and the other end of the first body member 1171 is used to connect the first connection mechanism 11 to an external device. The first connecting member 1172 is sleeved outside the first body member 1171. The first connecting member 1172 can connect and fix the first body member 1171 to the inner wall of the first housing assembly 116. At the same time, the first connecting member 1172 also serves to divide the first chamber 111 into two completely isolated first inlet chambers 1111 and first outlet chambers 1112. Specifically, the first body member 1171 is made of a material with good electrical conductivity such as metal, and the first connecting member 1172 is made of a material with good insulation such as a polymer material. The first body member 1171 needs to be interconnected with the inner conductor 21 of the coaxial cable 200, and the first housing assembly 116 needs to be connected to the outer conductor 22 of the coaxial cable 200. The first body member 1171 with good electrical conductivity can better connect the inner conductor 21 of the coaxial cable 200 to an external device. The first connecting member 1172 with good insulation can play an insulating role between the first body member 1171 and the first housing assembly 116, avoiding a short circuit between the first body member 1171 and the first housing assembly 116, and thus avoiding a short circuit between the inner conductor 21 and the outer conductor 22 of the coaxial cable 200. At the same time, the first connecting member 1172 can also play a role in positioning and fixing the position of the first body member 1171 in the first chamber 111, avoiding the situation where the position of the first body member 1171 in the first chamber 111 is easily changed, and ensuring and improving the connection convenience and smoothness between the first connection mechanism 11 and the coaxial cable 200.
[0052] As an alternative implementation, as Figure 10 and Figure 11As shown, the first body member 1171 includes a first head 1171a, a first tail 1171b, a first connecting sleeve 1171c, and a first anti - detachment portion 1171d. One end of the first head 1171a is used to connect to an external device, the first tail 1171b is connected to the other end of the first head 1171a, and the end of the first tail 1171b away from the first head 1171a is used to connect to the inner conductor 21 of the coaxial cable 200. The first head 1171a is hollow, the first tail 1171b is hollow, and after the first tail 1171b is connected to the first head 1171a, a first tubular channel 114 is formed. A first through - hole 115 is provided in the first head 1171a.

The first housing assembly 116 is in the form of a combination of multiple components, which can increase the convenience of operations such as the installation and replacement of the first connector 117 within the first housing assembly 116, and can also enhance the convenience of connecting the coaxial cable 200 to the first connection mechanism 11. The first housing assembly 116 formed by the combination of multiple components also has diversity, and different components can be selected for combination according to actual needs, enabling it to adapt to a wider range of application scenarios. The first middle shell 1162 is connected to the first head shell 1161.

By the method of fixing the first connector 117 after connecting the first middle shell 1162 and the first head shell 1161, the difficulty of fixing the first connector 117 is reduced, facilitating wide-range application. At the same time, after fixing by this method, a good fixing and connection strength can also be achieved between the first connector 117 and the first housing assembly 116. The first tail shell 1163 is connected to one end of the first middle shell 1162 away from the first head shell 1161. After the first tail shell 1163 is connected to the first middle shell 1162, a first sealing groove 1165 can be formed. The first sealing groove 1165 can be used to place a sealing member. The first tail shell 1163 is located at one end where the first connection mechanism 11 is connected to the coaxial cable 200. The first tail shell 1163 needs to be connected to the outer conductor 22 of the coaxial cable 200. After setting a sealing member at the position of the first tail shell 1163, the connection sealing performance between the first connection mechanism 11 and the coaxial cable 200 can be increased, especially the connection sealing performance between the first connection mechanism 11 and the outer conductor 22 of the coaxial cable 200, avoiding leakage and other situations in the second fluid channel 24 of the outer conductor 22. At the same time, setting a sealing member at this position can also increase the connection stability. For the connection structure between the first head shell 1161, the first middle shell 1162, and the first tail shell 1163, preferably, the first middle shell 1162 and the first head shell 1161 can be fixed to each other by using fasteners, and the first head shell 1161 and the first middle shell 1162 can be fixed to each other by using a snap structure.

Different from the first connector 117, the second connecting member 1252 in the second connector 125 does not divide the second chamber 121 into two completely isolated chambers. A plurality of channels are provided in the second connecting member 1252, so that the parts of the second chamber 121 on both sides of the second connecting member 1252 can communicate with each other. The second body member 1251 is made of a material with good electrical conductivity such as metal, and the second connecting member 1252 is made of a material with good insulation such as a polymer material. The second body member 1251 needs to be connected to the inner conductor 21 of the coaxial cable 200, and the second housing assembly 124 needs to be connected to the outer conductor 22 of the coaxial cable 200. The second body member 1251 with good electrical conductivity can better connect the inner conductor 21 of the coaxial cable 200 to an external device. The second connecting member 1252 with good insulation can play an insulating role between the second body member 1251 and the second housing assembly 124, avoiding a short circuit between the second body member 1251 and the second housing assembly 124, and further avoiding a short circuit between the inner conductor 21 and the outer conductor 22 of the coaxial cable 200. At the same time, the second connecting member 1252 can also play a role in positioning and fixing the position of the second body member 1251 in the second chamber 121, avoiding the situation that the position of the second body member 1251 in the second chamber 121 is easily changed, and ensuring and improving the connection convenience and smoothness between the second connection mechanism 12 and the coaxial cable 200.
[0055] As an alternative implementation, as Figure 15 and Figure 16As shown, the second body member 1251 includes a second head 1251a, a second tail 1251b, a second connecting sleeve 1251c, and a second anti - detachment portion 1251d. One end of the second head 1251a is used to connect to an external device. The second tail 1251b is connected to the other end of the first head 1171a. The end of the second tail 1251b away from the second head 1251a is used to connect to the inner conductor 21 of the coaxial cable 200. The second head 1251a is hollow - provided, and the second tail 1251b is hollow - provided. After the second tail 1251b is connected to the second head 1251a, a second tubular channel 122 is formed. A second through - hole 123 is provided in the second head 1251a. The second connecting sleeve 1251c is sleeved on the outer side of the second tail 1251b. The second anti - detachment portion 1251d is provided between the second connecting sleeve 1251c and the second tail 1251b, and the second anti - detachment portion 1251d is provided away from the second head 1251a.

The second tail 1251b is connected to the second head 1251a, and the second tail 1251b is used to connect to the inner conductor 21 of the coaxial cable 200. The second tail 1251b and the inner conductor 21 of the coaxial cable 200 not only achieve mechanical connection but also can achieve electrical connection. The second head 1251a and the second tail 1251b are connected to form the main body part of the second body member 1251, which can play a role in electrically connecting the inner conductor 21 of the coaxial cable 200 to an external device. At the same time, after the second tail 1251b and the second head 1251a are connected, a second tubular channel 122 can be formed, and this second tubular channel 122 can be connected to the second fluid channel 24 of the inner conductor 21 of the coaxial cable 200, playing a role in conveying fluid. The outer side of the second connecting sleeve 1251c is provided with a thread. The threaded second connecting sleeve 1251c can better connect with the threaded inner conductor 21, enhancing the connection reliability between the second body member 1251 and the inner conductor 21. The setting of the second anti - detachment portion 1251d can further improve the connection reliability after the second body member 1251 and the inner conductor 21 are connected, avoiding situations such as detachment during use. In the embodiment of the present application, the second body member 1251 can adopt exactly the same structure and components as the first body member 1171, which can also reduce the manufacturing cost and manufacturing difficulty of the connector assembly.
[0056] As an alternative embodiment, as Figure 17As shown, the second housing assembly 124 includes a second head shell 1241, a second middle shell 1242, and a second tail shell 1243. The second housing assembly 124 adopts a form of combining multiple components, which can increase the convenience of operations such as the installation and replacement of the second connector 125 within the second housing assembly 124, and can also enhance the convenience of connecting the coaxial cable 200 to the second connection mechanism 12. The second housing assembly 124 formed by combining multiple components also has diversity. Different components can be selected for combination according to actual needs, enabling it to adapt to a wider range of application scenarios. The second middle shell 1242 is connected to the second head shell 1241. After the second middle shell 1242 and the second head shell 1241 cooperate with each other, a second connection groove 1244 can be formed, and the second connection groove 1244 can be used to accommodate and fix the second connector 125. Specifically, the second connecting member 1252 in the second connector 125 can be fixed in the second connection groove 1244 (as shown in Figure 5). By the method of fixing the second connector 125 after connecting the second middle shell 1242 and the second head shell 1241, the difficulty of fixing the second connector 125 is reduced, facilitating wide - range application. At the same time, after fixing by this method, a good fixing and connection strength can also be achieved between the second connector 125 and the second housing assembly 124. The second tail shell 1243 is connected to one end of the second middle shell 1242 away from the second head shell 1241. After the second tail shell 1243 is connected to the second middle shell 1242, a second sealing groove 1245 can be formed, and the second sealing groove 1245 can be used to place a sealing member. The second tail shell 1243 is located at one end where the second connection mechanism 12 is connected to the coaxial cable 200. The second tail shell 1243 needs to be connected to the outer conductor 22 of the coaxial cable 200. After setting a sealing member at the position of the second tail shell 1243, the connection sealing performance between the second connection mechanism 12 and the coaxial cable 200 can be increased, especially the connection sealing performance between the second connection mechanism 12 and the outer conductor 22 of the coaxial cable 200, avoiding situations such as leakage in the second fluid channel 24 of the outer conductor 22. At the same time, setting a sealing member at this position can also increase the connection stability. Regarding the connection structure between the second head shell 1241, the second middle shell 1242, and the second tail shell 1243, preferably, the second middle shell 1242 and the second head shell 1241 can be fixed to each other by using fasteners, and the second head shell 1241 and the second middle shell 1242 can be fixed to each other by using a snap - fit structure. Of course, it can be understood that other connection methods can also be used to connect the second head shell 1241, the second middle shell 1242, and the second tail shell 1243. The second middle shell 1242 and the second head shell 1241 and the second tail shell 1243 can also be connected by using fasteners, and the second middle shell 1242 and the second head shell 1241 and the second tail shell 1243 can also be connected by using snap - fits, as long as the connection strength in the corresponding application scenarios can be ensured.
[0057] As an alternative embodiment, as Figure 18 shown, the first housing assembly 116 is further provided with at least one connecting nozzle 1166. The connecting nozzle 1166 is connected to at least one of the injection hole 112 or the discharge hole 113 and is in communication with the injection hole 112 or the discharge hole 113. The connecting nozzle 1166 can facilitate the injection of fluid into the injection hole 112 or the discharge of fluid from the discharge hole 113. Preferably, at least a connecting nozzle 1166 communicating with the injection hole 112 is provided. Usually, corresponding equipment is needed to inject fluid. Therefore, setting the corresponding connecting nozzle 1166 at the injection hole 112 can greatly improve the convenience of equipment connection and also improve the speed and convenience of fluid injection. For the discharge hole 113, if the circulated fluid is directly emptied, a connecting nozzle 1166 may not be provided in the discharge hole 113, which can reduce the overall manufacturing cost of the connector assembly and also reduce the overall size of the first connecting mechanism 11. For the case where the fluid needs to be recovered or recycled again after being discharged from the coaxial cable 200, setting the corresponding connecting nozzle 1166 in the discharge hole 113 can also greatly improve the convenience of equipment connection and also improve the speed and convenience of fluid recovery or recycling.
[0058] On the other hand, the present application also provides a coaxial cable assembly 300 (as Figure 3 shown). The coaxial cable assembly 300 includes a coaxial cable 200 and a coaxial cable connector assembly 100. The coaxial cable connector assembly 100 is connected to both ends of the coaxial cable 200. The coaxial cable 200 includes a hollow inner conductor 21 and a hollow outer conductor 22. The outer conductor 22 is sleeved outside the inner conductor 21. A first fluid channel 23 is formed in the inner conductor 21, and a second fluid channel 24 is formed between the outer conductor 22 and the inner conductor 21. As Figure 19 shown, the first connecting mechanism 11 is connected to the first end of the coaxial cable 200, and the second connecting mechanism 12 is connected to the second end of the coaxial cable 200. The first tubular channel 114 communicates with the first end of the first fluid channel 23, and the second tubular channel 122 communicates with the second end of the first fluid channel 23. The first chamber 111 communicates with the first end of the second fluid channel 24, and the second chamber 121 communicates with the second end of the second fluid channel 24. Among them, the injection hole 112, the first inlet chamber 1111, the first through hole 115, the first tubular channel 114, the first fluid channel 23, the second tubular channel 122, the second through hole 123, the second chamber 121, the second fluid channel 24, the first outlet chamber 1112, and the discharge hole 113 are connected in sequence to form a flow channel through which fluid can flow.
[0059] In the embodiment of the present application, the flow direction of the fluid in the coaxial cable assembly 300 (as Figure 19The direction indicated by the arrow (in the figure) is basically from the first fluid channel 23 to the second fluid channel 24, that is, the injected fluid first flows through the interior of the inner conductor 21 and then flows between the inner conductor 21 and the outer conductor 22. Such a setting can better and more quickly carry out the heat in the inner conductor 21 through fluid circulation. Even if the heat in the inner conductor 21 cannot be completely discharged outside the coaxial cable assembly 300, this part of the heat can also be circulated to the second fluid channel 24, making the heat in the entire coaxial cable 200 more uniform. After the heat is evenly distributed, the deformation problem caused by the temperature difference at various parts inside the coaxial cable 200 can be solved, the structural stability of the coaxial cable 200 can be improved, and further the power flow of the coaxial cable 200 during application can be increased.
