Description

A high-efficiency filament clamping device that can be connected to different numbers of power sources Technical Field

[0001] This utility model belongs to the technical field of filament mounting structure, specifically a high-efficiency filament clamping device that can be connected to different numbers of power supplies. Background Technology

[0002] In the field of space electron flow technology, electron flow density is a core technical indicator that determines system performance. During the thermionic emission process, traditional filament assemblies suffer from unintended heat dissipation through the clamping device due to the thermal conduction effect between the filament and the conductive support structure, which severely restricts the improvement of electron flow density. Furthermore, in compact device architectures, traditional discrete filament assemblies are limited by the spatial layout of the power supply system.

[0003] Existing technologies generally employ an integrated filament structure with a single power supply system. This architecture suffers from geometrical continuity in the heat conduction path, leading to an uncontrollable increase in heat dissipation area. Furthermore, it is difficult to add power supplies to achieve flexible control according to the segmented electron flow requirements.

[0004] Therefore, there is an urgent need to develop new filament integrated systems that can optimize thermal management and provide flexible control of multiple power sources while meeting the dynamic regulation requirements of multi-directional electron flow in compact spaces.

[0035] Example 1

[0036] Existing clamping devices suffer from high unintended heat dissipation. When a single long filament is installed, the filament is prone to drooping and contacting other metal parts, causing device failure. Therefore, a more efficient filament clamping device was designed, as follows:

[0037] As shown in Figures 1-3, a high-efficiency filament clamping device that can be connected to different numbers of power sources includes: a base 1 and a pair of conductive posts 2 mounted on the base 1, a continuous long filament 4 connected between the conductive posts 2, and the conductive posts 2 being electrically connected to an external power source.

[0038] When the filament 4 is heated by a large current, its length increases and it droops, which may cause it to come into contact with metals of different potentials, resulting in device failure. In this embodiment, a support structure is provided on the base 1 to provide physical support for the filament 4.

[0039] The support structure is an inverted "Y" shape. It includes a support base 301, a guide rail 302, a limiting member 304, and a slider 303. The slider 303 has a "U" shape. The limiting member 304, a square sheet structure, is mounted on the slider 303. The upper part of the limiting member 304 has a through hole 3041 for the filament 4 to pass through, and the lower part has a connecting hole. Screws are used to connect the limiting member 304 to the upper part of the slider 303. The slider 303 is connected to the guide rail 302. Bolts are located at the bottom of the slider 303, allowing control of the tightness between the slider 303 and the guide rail 302 to adjust the position of the slider 303. The guide rail 302 has two... The end is provided with a connecting part, which is fixedly connected to the support base 301 by screws.

The upper insulating part 305 and the lower insulating part 306 are equivalent to insulating gaskets. The support base 301 is fixedly connected to the base 1 by installing screws from bottom to top on the lower insulating part 306.

The external power supply is equipped with a matching plug, and the plug hole can be quickly plugged in to improve the efficiency of disassembly and assembly.

[0042] The base 1 has multiple mounting holes 101, which can be either through holes or countersunk holes. In this embodiment, the base 1 is a long strip block structure. Through holes are provided at both ends of the base 1 for the installation of conductive posts 2. Multiple elliptical countersunk holes are symmetrically provided on the top and bottom surfaces of the base 1 between the two through holes. Two through holes are provided in each countersunk hole. Screw holes are provided at the bottom of the support base for the installation of the support structure.

[0043] In this embodiment, the filament clamping device provides physical support for the filament 4 after it has been heated by a large current, by setting a support structure between the single long filaments 4. This prevents the filament 4 from drooping and coming into contact with the metal. Insulating components are provided between the conductive post 2, the support structure and the base 1, which reduces the heat conduction efficiency of the device and reduces heat dissipation.

[0058] The base 1 is a long strip-shaped block structure. Through holes are opened at both ends of the base 1 for the installation of conductive posts 2. Multiple elliptical countersunk holes are symmetrically opened on the top and bottom surfaces of the base 1 between the two through holes. Each countersunk hole has two through holes for the installation of the support structure.

[0059] The support structure includes two fixing components. Each fixing component includes a pair of conductive blocks 3011, a connector 309, and two clamping blocks 3010. The conductive blocks 3011 have an inverted "F" shape and are fixedly installed on the base 1. An insulating component is sleeved at the connection between the conductive blocks 3011 and the base 1.

[0060] Example 6

[0061] As shown in Figure 9, the structure of the clamping device is basically the same as that of Embodiment 1. The difference is that the device includes a base 1 and three pairs of conductive posts 2. The three pairs of conductive posts 2 are electrically insulated from each other, and a short filament 4 is connected to each of the three pairs of conductive posts 2.

[0062] The base 1 is a long strip-shaped block structure. Circular through holes are opened at both ends of the base 1 for the installation of conductive posts 2. Multiple circular through holes are also opened between the two end through holes of the base 1 for the installation of conductive posts 2.

[0063] The conductive post 2 is a rod-shaped structure with a limiting part in the middle.

[0065] The filament clamping device in this solution is designed with an adjustable support structure. Dynamic compensation is achieved through the limiting of the slider 303 and the oblong guide rail 302, which effectively prevents the short circuit risk caused by the filament 4 sagging due to heat and adapts to the deformation of the filament 4 under working conditions.

[0066] The double-layer insulating pad or tubular insulating sleeve 202, as well as the insulating base 308 and the limiting base 203, make the conductive post 2, the supporting structure and the base 1 electrically insulated, increase the thermal resistance and significantly reduce the heat conduction loss to the base 1.

[0067] The structural design supports the combined use of one or more filaments 4, and allows for independent control of multiple filaments 4, making it easy to adjust the electron flux density in different working areas.

[0068] The structural design of the conductive post 2 and the base 1 allows for the rapid replacement of the entire filament clamping device and its components.

[0069] It reduces the heat loss of filament 4, improves the recombination efficiency of filament 4, and improves the space utilization of filament 4, thereby improving the precision of electron flow control and energy efficiency in fields such as plasma equipment and electron beam processing.
