Description

Technical Field

[0001] This utility model relates to the field of electronic equipment, and more specifically, to a conductor assembly and a microwave device. Background Technology

[0002] In electronic devices, it is often necessary to connect one conductor to another. Current technology typically uses welding; however, this conventional connection method is unreliable, often resulting in weld cracks and failure of the connection between the two conductors. Utility Model Content

[0003] The purpose of this invention is to provide a conductor assembly that enables two conductors to be firmly connected, reducing the risk of loosening.

[0004] Another objective of this invention is to provide a microwave device that employs the aforementioned conductor assembly.

[0005] This utility model is implemented as follows:

[0006] A conductor assembly, comprising:

[0007] The first conductor is a hollow tubular structure, and a circular sidewall through hole is provided on the sidewall of the first conductor.

[0008] The second conductor includes a connector and a body;

[0009] The connector is connected to one end of the body. The connector is cylindrical in shape and has a tapered through hole. The larger diameter end of the tapered through hole faces the body.

[0010] The connector is inserted into the through hole in the side wall;

[0011] The body is provided with a body through hole extending along its length direction. The body through hole and the tapered through hole are coaxially arranged. A sliding rod is provided in the body through hole. The sliding rod is slidably arranged in the body through hole.

[0012] The end of the sliding rod can abut against the inner wall of the tapered through hole and be fixed in the corresponding position, so that the connector is subjected to radial force, thereby making the connector tightly connected to the side wall through hole.

[0013] Furthermore, the connector is provided with at least one gap, which extends along the axial direction of the connector and divides the connector into at least two parts; when the connector is subjected to radial force, the at least two parts can move closer to or further away from each other, so that the outer diameter of the connector decreases or increases accordingly.

[0014] Furthermore, a sphere is provided inside the tapered through hole, and the end of the sliding rod can abut against the sphere.

[0015] Furthermore, the taper of the tapered through hole enables the sphere and the connector to achieve self-locking, the sliding rod is connected to the sphere, and the length of the sliding rod is greater than the length of the through hole in the body.

[0016] Furthermore, a nut is provided at the end of the through hole of the body away from the connector, the nut is provided with a threaded hole, the sliding rod is provided with an external thread, and the sliding rod is disposed in the threaded hole.

[0017] Furthermore, the sliding rod is connected to the sphere via a connecting rope.

[0018] Furthermore, the first conductor is also provided with a negative pressure pipe connection port, which is used to connect a negative pressure pump so that the inner cavity of the first conductor is under negative pressure.

[0019] Furthermore, a sealing ring is fitted onto the sliding rod; a sealing ring is also provided between the end of the body and the outer wall of the first conductor.

[0020] Furthermore, the length of the second conductor is one-quarter of the wavelength of the microwave signal within the first conductor.

[0021] Furthermore, a gas container is connected to the end of the body through hole away from the connector, the gas container being used to contain compressed air.

[0022] A microwave device includes a housing and the conductor assembly, the conductor assembly being disposed within the housing, and a second conductor being connected to the inner wall of the housing.

[0023] The beneficial effects of this utility model are:

[0024] In this invention, the conductor assembly obtained by the above design has a second conductor inserted into the side wall through hole via a connector. Then, the end of the sliding rod abuts against the inner wall of the tapered through hole and is fixed in the corresponding position, thereby causing the connector to be subjected to radial force from the sliding rod, which in turn causes the outer wall of the connector to be tightly connected to the inner wall of the side wall through hole.

[0025] Compared to traditional welding, where the weld bead is in direct contact with the conductor, and the conductor generates a large amount of heat during operation and cools down after operation, the different coefficients of thermal expansion between the weld bead and the conductor cause the weld to crack and the connection to fail. If screw connections are used, multiple threaded holes need to be machined on the first conductor, and the screws are also prone to loosening due to thermal expansion and contraction. The conductor assembly provided in this application offers a more reliable connection that is less prone to loosening. Electronic devices using this conductor assembly exhibit significantly higher operational reliability. Attached Figure Description

[0031] like Figure 1 and Figure 2 This embodiment provides a conductor assembly, which includes a first conductor 1 and a second conductor 2. The first conductor 1 is a hollow tubular structure, and a circular sidewall through hole is provided on the sidewall of the first conductor 1. The second conductor 2 is inserted into the sidewall through hole to form a conductor assembly.

[0032] The first conductor 1 mentioned above is generally used to transmit electromagnetic signals. When it transmits signals, it generates a lot of heat. Therefore, it is necessary to set a second conductor 2 on its side wall to transfer the heat to the device housing through the second conductor 2.

[0033] The second conductor 2 includes an integrally formed connector 21 and a body 22. The connector 21 is generally cylindrical and has a tapered through-hole, with the larger diameter end of the tapered through-hole facing the body 22. The body 22 has a body 22 through-hole arranged along its length, coaxially with the tapered through-hole, and the diameter of the body 22 through-hole is larger than the larger diameter of the tapered through-hole. In other embodiments, the connector 21 is not limited to being cylindrical; its shape can also be square.

[0034] A sliding rod 3 is provided inside the through hole of the body 22. The sliding rod 3 can slide freely inside the through hole of the body 22. After the sliding rod 3 slides to a preset position, the sliding rod 3 can abut against the inner wall of the tapered through hole; and the sliding rod 3 can be held in this position, so that the connector 21 is subjected to radial force, which makes the outer wall of the connector 21 tightly connected with the inner wall of the side wall through hole.

[0035] Furthermore, in order to ensure that the overall outer diameter of the connector 21 increases accordingly when subjected to an outward radial force, the connector 21 in this embodiment is divided into multiple parts along its axial direction, with a gap 211 provided between adjacent parts. When the sliding rod 3 abuts against the inner wall of the tapered through hole, the radial force causes the multiple parts to move away from each other, thereby increasing the outer diameter of the connector 21 accordingly. In other embodiments, the connector 21 may not be divided into multiple parts. In this case, the connector 21 can be made of a material that is easily elastically deformable, and a thinner wall thickness can achieve the change in the outer diameter of the connector 21.

[0036] In addition, in order to reduce the friction between the end of the sliding rod 3 and the connector 21, a ball 4 is provided at the end of the sliding rod 3; the sliding rod 3 abuts against the connector 21 through the ball 4, which can also apply radial force to the connector 21 and reduce the friction.

[0037] To ensure the sliding rod 3 remains in the contact position and to prevent loosening of the connection due to temperature changes in the first conductor 1, a negative pressure adsorption method is employed in this embodiment. Specifically, the first conductor 1 is provided with a negative pressure connection port, which is connected to a negative pressure pump via a negative pressure pipe. The negative pressure pump maintains a negative pressure inside the first conductor 1. Therefore, even if temperature changes in the first conductor 1 cause the connection to loosen, the negative pressure inside the first conductor 1 can continuously draw the sphere 4 and the sliding rod 3 inward, thereby maintaining a tight fit between the connector 21 and the side wall through-hole.

[0038] In addition, to improve airtightness, a sealing ring is fitted on the sliding rod 3; a sealing ring is also provided between the end of the body 22 and the outer wall of the first conductor 1.

[0039] Furthermore, the length of the second conductor 2 is one-quarter of the wavelength of the microwave signal in the first conductor 1; thereby preventing the second conductor 2 from affecting the transmission of the signal in the first conductor 1.

[0040] The conductor assembly provided in this embodiment operates on the following principle:

[0041] When it is necessary to connect the second conductor 2 to the first conductor 1, the connector 21 is inserted into the side wall through hole, and then the sliding rod 3 is pushed so that the sliding rod 3 abuts against the ball 4; at this time, the end of the sliding rod 3 protrudes from the body 22 through hole for easy disassembly. Then, the inner cavity of the first conductor 1 is evacuated, so that the inner cavity generates negative pressure; under the action of atmospheric pressure, the push rod can continuously apply a large thrust to the ball 4, thereby allowing the ball 4 to apply a large radial pressure to the connector 21, so that the connector 21 and the side wall through hole can fit tightly. Since atmospheric pressure can continuously apply a thrust to the sliding rod 3, and the ball 4 and the conical through hole have a self-locking effect; therefore, no matter how the temperature of the first conductor 1 changes, the first conductor 1 and the second conductor 2 can maintain a reliable connection, avoiding loosening due to temperature changes.

[0042] Furthermore, if screws are used for connection, multiple threaded holes need to be machined on the first conductor 1, and screws are prone to loosening due to thermal expansion and contraction. Moreover, if the threads of the threaded holes are damaged, it may prevent the first conductor 1 from connecting to the second conductor 2. The connection method provided in this embodiment completely avoids these problems.

[0043] When disassembly is required, simply introduce air into the cavity of the first conductor 1 and then pull out the sliding rod 3. Example

[0044] like Figure 3 This embodiment provides another conductor assembly, which differs from Embodiment 1 in that the inner cavity of the first conductor 1 does not need to be evacuated, and the sliding rod 3 can be connected to the second conductor 2, so that the sliding rod 3 can continuously press against the sphere 4.

[0045] Specifically, a nut 222 is fixedly installed at the outer end of the through hole of the body 22, and the diameter of the threaded hole of the nut 222 is smaller than the diameter of the through hole of the body 22; the sliding rod 3 is provided with external threads and is disposed in the threaded hole of the nut 222. When the sliding rod 3 is rotated, the sliding rod 3 can move axially, thereby pressing the ball 4 against the inner surface of the tapered through hole; thus, the connector 21 can be tightly fitted with the side wall through hole. The threaded connection method of this embodiment is less affected by thermal expansion and contraction because it is far away from the heat source (i.e., the first conductor 1), and under the self-locking action of the tapered through hole, a reliable connection can be maintained between the first conductor 1 and the second conductor 2.

[0046] To facilitate the rotation of the sliding rod 3, a crank handle is provided at the outer end of the sliding rod 3.

[0047] For easy disassembly, the inner end of the sliding rod 3 is connected to the ball 4 via a connecting rope (not shown in the figure). When the sliding rod 3 is rotated to retract outward, the sliding rod 3 pulls the ball 4 out of the conical through hole via the connecting rope. Alternatively, in other embodiments, the sliding rod 3 may be directly fixedly connected to the ball 4. Example

[0048] like Figure 4 This embodiment provides a conductor assembly that differs from Embodiment 1 in that the inner cavity of the first conductor 1 does not need to be connected to a negative pressure pump. Instead, a gas container 5 is provided at the end of the through hole of the body 22 of the second conductor 2. This gas container 5 is used to fill compressed air. The compressed air in the gas container 5 can continuously apply a thrust to the sliding rod 3, so that the sliding rod 3 can continuously press the ball 4 tightly.

[0049] Specifically, the outlet pipe of the gas container 5 is detachably mounted on the end of the through hole of the main body 22, and the sliding rod 3 is also covered inside the outlet pipe; the gas container 5 can be made of an elastic deformable material, and the elasticity of the gas container 5 itself can also increase the pressure of the compressed air. Alternatively, an air pump can be directly connected to the gas container 5.

[0050] Furthermore, a through hole is provided on the side wall of the first conductor 1 to facilitate communication with atmospheric pressure; thereby facilitating the compression of air to drive the sliding rod 3. Example

[0051] This embodiment provides an electronic device having a housing and a conductor assembly as described in embodiments 1, 2, or 3, wherein the end of the second conductor 2 is fixedly connected to the housing. The second conductor 2 serves both to fix the first conductor 1 and to conduct heat, allowing the heat from the first conductor 1 to be quickly transferred to the housing via the second conductor 2, thereby facilitating heat dissipation.

[0052] If the conductor assembly of Embodiment 1 or 2 is used, the sliding rod 3 can slide freely through and protrude outside the housing, thus facilitating operation; if the conductor assembly of Embodiment 3 is used, the gas container 5 can be placed outside the housing, thus facilitating operation.

[0053] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
