Description

Technical Field

[0001] The utility model relates to the technical field of anti - conductive structures, and more specifically, the utility model relates to an anti - conductive structure for a vacuum power type electrode. Background Art

[0002] A vacuum power type electrode is a sealing device that can penetrate the vacuum chamber wall and transmit electric power, electrical signals, etc. at the atmospheric end to the inside of the vacuum chamber. Its principle is mainly to use electrodes made of metal for energy or signal transmission, and achieve efficient and low - loss power transmission through a vacuum environment.

[0003] The existing anti - conductive structure of the vacuum power type electrode only relies on the size of the designed gap between the electrode rod and the outer wall of the electrode, and cannot prevent the phenomenon of the electrode being electrically connected to external metal parts. When the current suddenly becomes abnormal, it is easy to be electrically connected to external metal parts, which is likely to cause electric shock to normal operators and endanger the safety of the operators themselves. Summary of the Utility Model

[0004] In order to overcome the deficiencies of the prior art, the utility model provides an anti - conductive structure for a vacuum power type electrode, which has the advantage of good pressing and sealing effect.

[0005] To achieve the above purpose, the utility model provides the following technical solution: an anti - conductive structure for a vacuum power type electrode, including a conductive rod, a ceramic is fixedly sleeved above the conductive rod, a welding alloy one is fixedly sleeved above the ceramic, an insulating ceramic two is movably sleeved above the conductive rod, a vacuum container wall plate is movably sleeved outside the insulating ceramic two, a KF center ring is movably sleeved at one end of the insulating ceramic two, the KF center ring is located on one side of the vacuum container wall plate, a KF half - open flange is movably installed on one side of the vacuum container wall plate, a connecting screw is movably installed on the side of the KF half - open flange, one end of the connecting screw passes through the left and right sides of the KF half - open flange in sequence and extends into the inside of the vacuum container wall plate, an insulating ceramic one is fixedly sleeved above the conductive rod, one end of the insulating ceramic one extends to the upper middle part of the ceramic, a KF joint is fixedly sleeved outside the insulating ceramic one, and a welding alloy two is movably sleeved on the side of the insulating ceramic one.

[0006] As a preferred technical solution of the utility model, one end of the connecting screw is located inside the vacuum container wall plate, and the connecting screw is threadedly sleeved with the KF half - open flange and the vacuum container wall plate.

[0007] As a preferred technical solution of the utility model, the top of the welding alloy two is movably connected to the bottom of the ceramic, and the KF joint is movably connected to the welding alloy two.

[0008] As a preferred technical solution of the present utility model, the bottom end of the first insulating ceramic is located inside the top end of the second insulating ceramic, and the outer diameter value of the second insulating ceramic is greater than the outer diameter value of the first insulating ceramic.

[0009] As a preferred technical solution of the present utility model, the KF center ring is located in the middle of the KF joint and the vacuum vessel wall plate, and the KF center ring is movably connected to the KF semi-open flange.

[0010] As a preferred technical solution of the present utility model, the number of the connecting screws is six, and each of the connecting screws is evenly distributed on the side surface of the KF semi-open flange.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] When the current flows through the conductive rod in the present utility model and encounters the second insulating ceramic, the inside of the second insulating ceramic prevents the current from penetrating, and the current only flows around it. When the current encounters the first insulating ceramic, the situation is the same. The side surface of the first insulating ceramic isolates the current, ensuring that the current passes through the conductive rod to the other end along the original path without obstruction. Compared with the traditional device, through the design of the second insulating ceramic and the first insulating ceramic, this device can prevent the phenomenon of electric connection between the electrode and the external metal parts, and will not cause electric shock to normal operators, thus endangering the safety of the operators themselves. At the same time, this device has a compact structure, is simple and easy to operate, can be installed at all angles, solves the problem of large current arcing and electric connection of the wire rod, and has a good compression sealing effect.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] As Figures 1 to 5 shown, the present invention provides a vacuum power type electrode anti-conduction structure, which includes a conductive rod 1. A ceramic 3 is fixedly sleeved above the conductive rod 1, and a welding alloy 1 2 is fixedly sleeved above the ceramic 3. An insulating ceramic 2 7 is movably sleeved above the conductive rod 1. A vacuum container wall plate 11 is movably sleeved outside the insulating ceramic 2 7. One end of the insulating ceramic 2 7 is movably sleeved with a KF center ring 8. The KF center ring 8 is located on one side of the vacuum container wall plate 11. A KF half-open flange 9 is movably installed on one side of the vacuum container wall plate 11. A connecting screw 10 is movably installed on the side of the KF half-open flange 9. One end of the connecting screw 10 sequentially penetrates the left and right sides of the KF half-open flange 9 and extends into the interior of the vacuum container wall plate 11. An insulating ceramic 1 6 is fixedly sleeved above the conductive rod 1. One end of the insulating ceramic 1 6 extends to the upper middle part of the ceramic 3. A KF joint 5 is fixedly sleeved outside the insulating ceramic 1 6. A welding alloy 2 4 is movably sleeved on the side of the insulating ceramic 1 6.

[0021] When current flows smoothly in the conductive channel of the conductive rod 1, it will inevitably encounter the insulating barrier of the insulating ceramic 2 7. Since the insulating ceramic 2 7 is made of carefully selected insulating materials and has extremely strong resistance to the penetration of current inside, although the current contacts the surface of the insulating ceramic 2 7, it can only flow around its outside and cannot penetrate its interior. Subsequently, the current continues to move forward. When it encounters the insulating ceramic 1 6, the situation remains the same. The insulating ceramic 1 6 is also an insulator, and its side effectively isolates the intrusion of current, ensuring that the current does not enter its interior but penetrates to the other end of the conductive rod 1 along the established path without hindrance.

[0022] When the current flows in the conductive rod 1 and encounters the insulating ceramic 2 7, the current is blocked from penetrating inside the insulating ceramic 2 7 and only flows around its outside. When the current encounters the insulating ceramic 1 6, the situation is the same. The side of the insulating ceramic 1 6 isolates the current, ensuring that the current passes through the conductive rod 1 to the other end along the original path without hindrance. Compared with traditional devices, through the design of the insulating ceramic 2 7 and the insulating ceramic 1 6, this device can prevent the phenomenon of electrical connection between the electrode and external metal parts, and will not cause electric shock to normal operators, thus endangering the safety of the operators themselves.

[0023] One end of the connecting screw 10 is located inside the wall plate 11 of the vacuum container, and the connecting screw 10 is threadedly sleeved with the KF half-open flange 9 and the wall plate 11 of the vacuum container.

[0024] By threadedly sleeving the connecting screw 10 with the KF half-open flange 9 and the wall plate 11 of the vacuum container, a firm connection and tightness are ensured, which is convenient for installation and disassembly.

[0025] Among them, the top of the welding alloy two 4 is movably connected to the bottom of the ceramic 3, and the KF joint 5 is movably connected to the welding alloy two 4.

[0026] Through the connection between the ceramic 3 and the welding alloy two 4, it is convenient for the assembly of the device. The components can be installed separately in small groups and then assembled together, which can achieve the sectional installation of the components and avoid time conflicts during installation.

[0027] Among them, the bottom end of the insulating ceramic one 6 is located inside the top end of the insulating ceramic two 7, and the outer diameter value of the insulating ceramic two 7 is greater than the outer diameter value of the insulating ceramic one 6.

[0028] Through the design of the insulating ceramic two 7 and the insulating ceramic one 6, the tightness of the connection between the insulating ceramic two 7 and the insulating ceramic one 6 is improved.

[0029] Among them, the KF center ring 8 is located between the KF joint 5 and the wall plate 11 of the vacuum container, and the KF center ring 8 is movably connected to the KF half-open flange 9.

[0030] Through the connection between the KF center ring 8 and the wall plate 11 of the vacuum container, the convenience of device operation can be improved, which is convenient for the assembly of the device.

[0031] Among them, the number of the connecting screws 10 is six, and each connecting screw 10 is evenly distributed on the side surface of the KF half-open flange 9.

[0032] Through the design of the connecting screw 10, the stability after installation can be improved, and the phenomenon of device separation can be avoided.

[0033] The working principle and usage process of the present utility model:

[0034] When the current flows smoothly in the conductive rod 1 as a conductive path, it will inevitably encounter the insulating barrier of the insulating ceramic two 7. Since the insulating ceramic two 7 is made of carefully selected insulating materials and has extremely strong resistance to the penetration of current inside, although the current contacts the surface of the insulating ceramic two 7, it can only flow around its outside and cannot penetrate its interior. Subsequently, the current continues to move forward. When it encounters the insulating ceramic one 6, the situation remains the same. The insulating ceramic one 6 also acts as an insulator, and its side effectively blocks the invasion of the current, ensuring that the current does not enter its interior but travels along the established path without hindrance to the other end of the conductive rod 1.
