Description

Technical Field

[0001] The present invention relates to the field of high-frequency signal transmission, and in particular to a conductor component. Background Art

[0002] In fields such as microwave communications, radio frequency systems, and high-speed digital circuits, the quality of connections between conductors directly affects the integrity of signal transmission and system performance. Traditional conductor connection methods, such as threaded connections, pogo pin contacts, or soldering, can meet requirements in low-frequency or DC applications, but have significant limitations in high-frequency (MHz to GHz) scenarios:

[0003] First, mechanical connections (such as bolted connections) can lead to unstable contact resistance due to microscopic gaps or oxide layers on the contact surface, thereby increasing signal attenuation and heat accumulation. Second, while soldering can reduce contact resistance, the inconsistency of the solder's dielectric properties can introduce parasitic capacitance or inductance, disrupting the impedance continuity of the transmission line and causing signal reflections. Furthermore, existing connection structures have poor adaptability to environmental stresses such as vibration and thermal cycling. After long-term use, connections are prone to loosening, further degrading high-frequency signal transmission performance and making it difficult to meet long-term stability requirements. Summary of the Invention

[0004] An object of the present invention is to provide a conductor assembly that can achieve low-loss, high-stability and tight connection between signal transmission conductors.

[0008] When compressed gas is continuously introduced into the compression chamber, the compressed gas can push the moving member to move in the sealed chamber, so that the end surface of the second conductor is tightly connected to the end surface of the first conductor.

[0011] Furthermore, in the present invention, the longitudinal section of the groove is in a stepped shape with increasing diameter from the inside to the outside, and the outer diameter of the moving part is smaller than the inner diameter of the smallest diameter portion of the groove.

[0012] Furthermore, in the present invention, the sealing plate has a stepped longitudinal section and is adapted to be embedded in the end of the groove, with its outer end surface flush with or lower than the outer end surface of the first conductor.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0026] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0027] Example 1

[0028] Please refer to Figure 1 , which is a schematic structural diagram of a conductor assembly according to an embodiment of the present invention;

[0029] The present embodiment provides a conductor assembly, comprising a first conductor 1 and a second conductor 2 that can be connected to each other, wherein a sealed cavity 11 is provided at the end of the first conductor 1, and the sealed cavity 11 is a closed cavity provided at the end of the first conductor 1. A moving part 21 is provided at the end of the second conductor 2, and the moving part 21 is movably provided in the sealed cavity 11, that is, the moving part 21 can move in the sealed cavity 11, thereby being able to drive the second conductor 2 to move toward or away from the first conductor 1, thereby achieving connection or release with the first conductor 1. The moving part 21 separates the sealed cavity 11 into a compression cavity 111 and an atmospheric pressure cavity 112 along the axial direction of the conductor; wherein the compression cavity 111 is externally connected to a compressed gas source 3, and compressed gas can be introduced into the compression cavity 111, and the atmospheric pressure cavity 112 is connected to the atmosphere, and the gas in the atmospheric pressure cavity 112 can be discharged, so that the pressure in the compression cavity 111 and the atmospheric pressure cavity 112 are inconsistent, thereby being able to push the moving part 21 to move.

[0030] Specifically, if Figure 1 The compression chamber 111 is located on the side close to the second conductor 2, and the atmospheric pressure chamber 112 is located on the side away from the second conductor 2. When compressed gas is continuously introduced into the compression chamber 111, the pressure in the compression chamber 111 increases, the gas in the atmospheric pressure chamber 112 is discharged, and the pressure decreases. The compressed gas can push the moving part 21 toward the side of the first conductor 1, and then drive the second conductor 2 to move toward the side of the first conductor 1, so that the end face of the second conductor 2 is tightly connected with the end face of the first conductor 1.

[0031] As an example, a gas delivery channel 13 is provided inside the first conductor 1. The gas delivery channel 13 extends inward from the side wall of the first conductor 1 and is divided into a plurality of branch channels that extend toward the compression chamber 111, respectively, until they are connected to the compression chamber 111. The compressed gas source 3 is provided on one side of the first conductor 1 and is connected to the inlet of the gas delivery channel 13. The compressed gas can be passed into the compression chamber 111 through the gas delivery channel 13 and the plurality of branch channels. An atmospheric pressure channel 14 is provided inside the first conductor 1 and is connected to the atmospheric pressure chamber 112. The atmospheric pressure channel 14 is connected to the outside of the first conductor 1 and can discharge the gas inside through the atmospheric pressure channel 14, thereby making the pressure of the atmospheric pressure chamber 112 lower than the pressure of the compression chamber 111, thereby achieving a tight connection of the conductors.

[0032] Furthermore, to facilitate quick and easy disassembly of the first and second conductors 1 and 2, the first conductor 1 is provided with a pressure relief passage 15. One end of the pressure relief passage 15 communicates with the compression chamber 111, while the other end communicates with the exterior of the conductor, with a sealing plug 7 positioned at the connection point. During disassembly, the sealing plug 7 is opened to quickly discharge the compressed gas within the compression chamber 111 through the pressure relief passage 15, aligning the pressures of both the compression chamber 111 and the atmospheric pressure chamber 112 with atmospheric pressure. The movable member 21 no longer exerts a pulling force on the second conductor 2, allowing for rapid separation of the first and second conductors 1 and 2. To reconnect the first and second conductors 1 and 2, the pressure relief passage 15 is sealed with the sealing plug 7.

[0033] As an example, a connecting rod 22 is provided at the end of the second conductor 2, and the movable member 21 is connected to the connecting rod 22. By providing the connecting rod 22, the movable member 21 is connected to the end of the second conductor 2, so that there is a certain distance between the movable member 21 and the end face of the second conductor 2. While being able to be movably set at a suitable position inside the sealed cavity 11, the end face of the second conductor 2 can be tightly connected to the end face of the first conductor 1.

[0034] Furthermore, in order to facilitate manufacturing and installation, the movable member 21 and the connecting rod 22 can be detachably connected, and specifically, the two can be connected and fixed by connecting members such as bolts.

[0035] As an example, the sealed cavity 11 can be composed of a groove provided at the end of the first conductor 1 and a sealing plate 12 detachably connected to the end of the groove, so that the movable part 21 can be detachably arranged in the sealed cavity 11. The sealing plate 12 is provided with a through hole 121, and the connecting rod 22 can movably pass through the through hole 121, so that the movable part 21 can move back and forth in the sealed cavity 11; and the connecting rod 22 is sealed with the inner wall of the through hole 121, which can prevent the compressed gas in the compression chamber 111 from leaking out. Specifically, the sealing plate 12 can be fastened to the end face of the groove by a plurality of internally sunken bolts, which is convenient for disassembly and assembly.

[0036] Furthermore, a first sealing ring 4 is provided between the outer wall of the connecting rod 22 and the inner wall of the through hole 121. The first sealing ring 4 can be embedded in the outer wall of the connecting rod 22 or the inner wall of the through hole 121. The first sealing ring 4 is made of rubber, which can improve the sealing performance between the connecting rod 22 and the through hole 121, enhance the sealing effect, and avoid compressed gas leakage resulting in the inability to effectively push the moving part 21, thereby causing the first conductor 1 and the second conductor 2 to be loosely connected.

[0037] A second sealing ring 5 is provided between the outer wall of the above-mentioned moving part 21 and the inner wall of the sealing chamber 11. The second sealing ring 5 is used to seal the outer ring surface of the moving part 21 and the inner wall of the sealing chamber 11, and can effectively separate the sealing chamber 11 into a compression chamber 111 and an atmospheric pressure chamber 112, thereby avoiding gas flow between the two and affecting the sealing effect of the compression chamber 111.

[0038] A third sealing ring 6 is provided at the edge of the butt joint surface between the first conductor 1 and the second conductor 2. The third sealing ring 6 is used to seal the edge of the butt joint surface between the first conductor 1 and the second conductor 2 to prevent the gas in the compression chamber 111 from leaking out from the butt joint surface, thereby further improving the sealing effect of the compression chamber 111.

[0039] As an example, in order to facilitate the processing of the gas delivery channel 13 and the filling of compressed gas, the longitudinal section of the above-mentioned groove is in a stepped shape with increasing diameter from the inside to the outside. The outer diameter of the moving part 21 is smaller than the inner diameter of the smallest part of the groove diameter, so that the moving part 21 can move in this part. At the same time, the diameter of the compression chamber 111 part is larger than the diameter of the atmospheric pressure chamber 112 part, which facilitates the connection between the gas delivery channel 13 and the compression chamber 111, avoids multiple bends in the channel, and makes the production simple.

[0040] Furthermore, in order to improve the tightness of the connection between the first conductor 1 and the second conductor 2, the longitudinal cross-section of the sealing plate 12 is also stepped and is adapted to be embedded at the end of the groove, matching the stepped structure of the groove end, and its outer end face is flush with or lower than the outer end face of the first conductor 1. In this way, the end face of the second conductor 2 can be tightly fitted with the end face of the first conductor 1, avoiding the formation of gaps that may cause gas leakage.

[0041] The working principle of the conductor assembly provided in this embodiment is as follows:

[0042] During assembly, after the connecting rod 22 passes through the through hole 121 of the sealing plate 12, the moving part 21 is connected to the end of the connecting rod 22 by bolts, and the moving part 21 is placed inside the sealing cavity 11, and then the sealing plate 12 is fixed to the end of the first conductor 1 by bolts. The pressure relief channel 15 is sealed with a sealing plug 7, and the entrance of the gas delivery channel 13 is connected to the compressed gas source 3. The compressed gas source 3 is turned on and compressed gas is continuously introduced into the compression chamber 111. The compressed gas pushes the moving part 21 to move toward the side of the first conductor 1, squeezing the atmospheric pressure cavity 112. The gas in the atmospheric pressure cavity 112 is discharged through the atmospheric pressure channel 14; the second conductor 2 is driven by the moving part 21 to move toward the side of the first conductor 1, so that its end face is closely fitted with the end face of the first conductor 1, achieving a tight connection.

[0043] The beneficial effects of the conductor assembly provided by this embodiment are as follows:

[0044] The introduction of compressed gas quickly establishes a tight connection between conductors, improving the connection quality. It also allows for quick separation of the first conductor 1 and the second conductor 2, making assembly and disassembly easy and simple. This prevents microscopic gaps between conductors during mechanical connection, which can lead to unstable resistance, and also prevents solder from introducing other materials into the welded connection, which can cause signal reflections. Furthermore, the compressed gas connection automatically adapts to deformation and stress caused by vibration, thermal expansion, and contraction, resulting in highly stable connections.

[0045] Example 2

[0046] Reference Figure 2 The conductor assembly provided in this embodiment is substantially the same as the conductor assembly in Example 1, except that the gas delivery channel 13 of this embodiment is provided in the second conductor 2.

[0047] Specifically, the gas delivery channel 13 extends inward from one side of the second conductor 2 and, after extending into the interior of the connecting rod 22, forms a plurality of branch channels that extend outward from the connecting rod 22 to communicate with the compression chamber 111. At this point, the compressed gas source 3 is disposed on one side of the second conductor 2 and communicates with the inlet of the gas delivery channel 13. The atmospheric pressure channel 14 is disposed on the first conductor 1 and extends from the atmospheric pressure chamber 112 to the exterior of the first conductor 1 to communicate with the external atmospheric pressure.

[0048] Furthermore, the pressure relief channel 15 may also be provided on the second conductor 2, extending from the side wall of the connecting rod 22 to the side wall of the second conductor 2 until it is connected to the external atmospheric pressure, and a sealing plug 7 may be provided at the connection point.

[0049] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
