However, the existing data cables have a single structure and function. When the data cables are used for a long time, the large amount of resistance heat generated by the circuit board may cause the circuit board to overheat and be damaged. The shell that encapsulates it is often not transparent, which makes it difficult to find the source of the fault, and the data cable has poor aesthetics. If an additional cooling structure is required, the terminals also involve components such as the circuit board and the shell. The commonly used overall integrated assembly of the data cable makes the internal structure of the data cable complex and the assembly is laborious and time-consuming.

[0042] See also Figure 1 and Figure 2 The embodiment of the utility model provides a circuit board assembly 121, including a circuit board 1211, a first positioning member 1212 and a second positioning member 1213. The first positioning member 1212 and the second positioning member 1213 are arranged on the circuit board 1211 at intervals, the first positioning member 1212 includes a first positioning structure 12121 and a first matching structure 12122, the second positioning member 1213 includes a second positioning structure 12131 and a second matching structure 12132, and the direction of the first positioning structure 12121 relative to the first matching structure 12122 and the direction of the second positioning structure 12131 relative to the second matching structure 12132 are consistent. The projection area of ​​the first positioning structure 12121 along the axial direction of the circuit board 1211 is not less than the projection area of ​​the second positioning member 1213 along the axial direction of the circuit board 1211. By arranging the first positioning member 1212 and the second positioning member 1213 on the circuit board 1211 at intervals, when it is applied to its corresponding matching shell 122, when the circuit board 1211 needs to be placed in the sealed shell 122, it is only necessary to connect the first positioning member 1212 and the second positioning member 1213 to the two ends of the shell 122, so as to quickly complete the sealing of the two ports of the shell 122, and accommodate the circuit board 1211 in its closed space, thereby improving the assembly efficiency of corresponding products such as the data line terminal 12.

[0043] It should be supplemented that the relationship between the first positioning member 1212 and the second positioning member 1213 and the circuit board 1211 exists in at least the following situations: the first positioning member 1212 and the second positioning member 1213 can be independent components not attached to the circuit board 1211. In this case, the first positioning member 1212 and the second positioning member 1213 need to be assembled with the circuit board 1211, and the assembly method can be snap-on or adhesive, etc.; in addition, the circuit board 1211, the first positioning member 1212 and the second positioning member 1213 can also be an integrally formed component prepared by injection molding and other technologies; in addition, the above two methods can be combined, one of the first positioning member 1212 and the second positioning member 1213 is an independent component, and the other is integrally formed with the circuit board 1211, etc., so as to better adapt to different application scenarios.

[0044] See also Figure 1 , Figure 2and Figure 3 The embodiment of the utility model also provides a data line terminal 12, which includes a housing 122, an interface 123, a flowing medium and the above-mentioned circuit board assembly 121. The housing 122 is defined as a receiving channel 1221, and the receiving channel 1221 penetrates the housing 122 at opposite ends in the axial direction to form a first port 12211 and a second port 12212. The interface 123 is arranged at one end of the circuit board 1211 close to the first positioning member 1212. The circuit board 1211 is at least partially received in the receiving channel 1221, the first positioning member 1212 is threadedly connected to the first port 12211 to close the first port 12211, and the second positioning member 1213 is threadedly connected to the second port 12212 to close the second port 12212. The receiving channel 1221 is filled with a flowing medium, which can flow freely in the receiving channel 1221.

[0045] The circuit board 1211 is accommodated in the accommodating channel 1221, and the accommodating channel 1221 is filled with a flowing medium, which can flow in the accommodating channel 1221, thereby increasing the rate at which the circuit board 1211 diffuses heat, enhancing heat dissipation, and extending the life of the data cable 1. In addition, both ends of the accommodating channel 1221 are respectively threadedly connected with the first positioning member 1212 and the second positioning member 1213 to close both ends of the housing 122 and prevent the flowing flowing medium from overflowing the housing 122. The first positioning member 1212 and the second positioning member 1213 have simple structures, and are easy to assemble with the housing 122, thereby simplifying the assembly process of the data cable 1 during manufacturing and improving production efficiency.

[0046] It should be added that the flowing medium is an insulating material that can directly contact the circuit board 1211. The physical state of the flowing medium mainly satisfies the requirement of being able to flow freely in the accommodating channel 1221. The specific state can be presented as liquid or fine solid particles or powder, such as coolant. In addition, there is no specific restriction on the color of the flowing medium or the shape and size of the solid particles, so as to create a variety of appearances, enhance the beauty of the data cable 1, and meet the various aesthetic needs of users.

[0047] For further information, see Figure 2 and Figure 3, threads are formed on the surfaces of the first positioning structure 12121 and the second positioning structure 12131 along the inner wall direction of the shell 122. In order to realize the rapid threaded connection between the shell 122 and the first positioning member 1212 and the second positioning member 1213, a first thread groove 1222 is opened on the inner wall of the shell 122 corresponding to the first positioning structure 12121, and a second thread groove 1223 is opened corresponding to the second positioning member 1213. The first positioning member 1212 is tightly fitted with the first thread groove 1222, and the second positioning member 1213 is also tightly fitted with the second thread groove 1223, so that the two ends of the accommodating channel 1221 can be closed after the threaded connection, so that the flowing medium can be stored in the accommodating channel 1221 without leaking out of the shell 122.

[0048] In addition, in addition to achieving the connection between the first positioning member 1212 and the second positioning member 1213 and the shell body by matching the first positioning structure 12121 with the first thread groove 1222 and the second positioning structure 12131 with the second thread groove 1223, in order to improve the stability of the connection between the first positioning member 1212 and the second positioning member 1213 and the shell body 122, and to further ensure the airtightness of the first positioning member 1212 and the second positioning member 1213 blocking the accommodating channel 1221, sealing measures such as bonding the first matching structure 12122 and the second matching structure 12132 and the end faces of the shell body 122 corresponding to the first port 12211 and the second port 12212 should also be adopted.

[0049] For further information, please refer to Figure 2 and Figure 3 The first positioning structure 12121 passes through the first port 12211 and is threadedly connected with the first thread groove 1222. The first matching structure 12122 is closely attached to the first port 12211 and is located outside the accommodating channel 1221. The maximum cross-sectional area of ​​the first matching structure 12122 is greater than the cross-sectional area of ​​the port of the accommodating channel 1221, so as to close the first port 12211. The first positioning structure 12121 is connected with the thread groove, the cross-sectional area of ​​the first matching structure 12122 is greater than the cross-sectional area of ​​the first port 12211, and the first matching structure 12122 is closely attached to the first port 12211 and is located outside the accommodating channel 1221, so as to achieve seamless sealing of the outer side of the first port 12211.

[0050] It should be added here that the first matching structure 12122 also wraps the circuit board 1211 and the interface 123 to improve the connection strength between the two.

[0051] For further information, see Figure 2 and Figure 4The inner wall of the shell 122 at least partially corresponds to the second positioning structure 12131 and protrudes along the radial direction of the shell 122 and toward the direction of the axial center line to form a boss 1224. The accommodating channel 1221 corresponds to the boss 1224 to form an inner hole 12241. The second matching structure 12132 is arranged on the side of the boss 1224 close to the first positioning member 1212, and the cross-sectional area of ​​the second matching structure 12132 is larger than the cross-sectional area of ​​the inner hole 12241, so that the second matching structure 12132 closes the inner hole 12241.

[0052] Here, at least a portion of the inner wall of the housing 122 corresponds to the second positioning structure 12131 and protrudes in the radial direction of the housing 122 and in the direction of the axial centerline to form a boss 1224, and the accommodating channel 1221 corresponds to the boss 1224 to form an inner hole 12241. By forming the boss 1224, the boss 1224 limits the second matching structure 12132, and further limits the second positioning member 1213 in the housing 122. The second matching structure 12132 is arranged on a side of the boss 1224 close to the first positioning member 1212, and the cross-sectional area of ​​the second matching structure 12132 is greater than the cross-sectional area of ​​the inner hole 12241, so that the second matching structure 12132 closes the inner hole 12241, thereby sealing the second port 12212.

[0053] It should be added here that the design of the boss 1224 is mainly aimed at achieving a radius of the inner hole 12241 that is smaller than the radius of the second matching structure 12132. It can be understood that the radius of the accommodating channel 1221 where the second matching structure 12132 is located should be greater than or equal to the radius of the second matching structure 12132. As a simple specific implementation method, the design of the boss 1224 can be reflected in the shell 122 as a step formed by the change in the radius size of the accommodating channel 1221, and the accommodating channel 1221 can be simply divided into two sections, the first section is from the first end face to the boss 1224, and the second section is from the boss 1224 to the second end face. The cross-sectional area of ​​the first section of the accommodating channel 1221 is greater than the cross-sectional area of ​​the second section. At this time, it is easy to understand that the space where the flowing medium can actually exist is the space formed by the accommodating channel 1221 between the second matching structure 12132 and the first positioning structure 12121.

[0054] For further information, see Figure 2 and Figure 3 At least one side of the circuit board 1211 forms a notch 12111 along the direction of the first positioning structure 12121 from one end of the second matching structure 12132 close to the first positioning member 1212. The notch 12111 enables the circuit board 1211 to be clamped on the side of the second sealing member away from the second positioning structure 12131 to position the second threaded member in the accommodating channel 1221.

[0055] For further information, see Figure 3and Figure 5 The data line terminal 12 further includes a first seal 124 and a second seal 125. The first seal 124 is sleeved on one end of the first positioning structure 12121 close to the first matching structure 12122, and the second seal 125 is sleeved on one end of the second positioning structure 12131 close to the second matching structure 12132. The first seal 124 and the second seal 125 are both interference-fitted with the accommodating channel 1221. The first seal 124 and the second seal 125 interference-fitted with the accommodating channel 1221 are provided to further seal the housing 122 to prevent leakage of the flowing medium.

[0056] It should be added that the materials of the first seal 124 and the second seal 125 are not specifically required as long as they do not interact chemically with the flowing medium. For example, silicone seals can be selected, which have good sealing effects and low costs.

[0057] For further information, see Figure 1 , Figure 2 and Figure 3 The second positioning member 1213 is provided with at least one feed channel 12133 penetrating the second positioning member 1213 along the axial direction of the housing 122, and the feed channel is connected to the accommodating channel 1221; the data line terminal 12 also includes a number of blocking members 126 corresponding to the number of feed channels 12133, so that the blocking members 126 block the feed channels 12133. By providing the feed channels 12133, the user can inject the flowing medium from the feed channels 12133 into the accommodating channel 1221; by equipping the feed channels 12133 with the blocking members 126 to block the feed channels 12133, the flowing medium is prevented from overflowing from the housing 122 through the feed channels 12133 and damaging the data line 1.

[0058] It should be added that there is no limitation on the number and specific shape of the feed channels 12133; the material of the plugging member 126 is specifically selected according to the properties of the flowing medium, such as a rubber plug.

[0059] For further information, see Figure 2 , the flowing medium is a flowing medium of insulating material, so as to achieve direct contact between the flowing medium and the circuit board 1211, and prevent the flowing medium and the circuit board 1211 from causing circuit interference and other effects. In addition, the housing 122 is at least partially transparent, so that the internal structure and the color, shape or flow state of the flowing medium are visible to the outside world, so that the data cable 1 has a multi-level aesthetic feeling, which helps to improve the aesthetics of the product. And when the internal components such as the circuit board 1211 are damaged or other faults occur, the fault source can be quickly checked to reduce the maintenance cost.
