Description

Technical Field

[0001] This utility model relates to the field of microfocus X-ray power supply technology, and in particular to high-voltage insulation technology for X-ray power supplies, specifically to an insulating housing for a microfocus X-ray power supply. Background Technology

[0002] Microfocus X-ray technology is a high-resolution X-ray imaging technique. Its core lies in using an extremely small X-ray source to generate high-definition images, and it is widely used in precision testing, materials analysis, electronics, and medical imaging. To ensure high image clarity, the high-voltage power supply must be stable with minimal ripple. This requires the power supply to avoid unstable factors, such as excessive component temperature rise or external electromagnetic interference, which can lead to voltage fluctuations and consequently, unclear images.

[0003] Existing high-voltage power supplies for microfocus X-rays still suffer from unstable high-voltage output. Electromagnetic interference affects image clarity, and excessive temperature rise prevents the X-ray equipment from operating continuously for extended periods, resulting in poor image stability and reduced work efficiency. Utility Model Content

[0004] To address the problems in the background technology, the purpose of this utility model is to provide an insulating housing for a micro-focus X-ray power supply. The high-voltage transformer and voltage multiplier circuit are placed inside the housing and encapsulated with insulating colloid. This not only solves the main insulation problem but also effectively solves other problems such as heat dissipation and shielding, thereby effectively improving the clarity of X-ray imaging.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An insulating housing for a microfocus X-ray power supply includes a housing column with an opening at the top and a circuit board groove formed on the symmetrical wall of its inner cavity. The bottom of the housing column is closed, with a terminal block pre-embedded in the middle and a circular end on the outer side of the bottom. A groove is provided on the outer side of the housing column. Both the housing column and the circular end are made of insulating material.

[0007] Preferably, the inner cavity of the housing column is a square or circular cavity, and the depth of the cavity matches that of the circuit board.

[0008] Preferably, the wall thickness of the shell column is 2 to 5 millimeters.

[0009] Preferably, the shell column is made of epoxy resin casting and is integral with the inner cavity, formed in one piece.

[0010] Preferably, the annular end and the inner cavity are integrally formed in one piece, with the end tapered inward.

[0011] Preferably, the height of the annular end is 25-35 mm.

[0012] Preferably, the terminal is made of copper and is cylindrical.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention places the high-frequency transformer and voltage multiplier circuit of the high-voltage generation part of the miniature X-ray high-voltage power supply inside the casing of this invention, effectively solving problems such as electromagnetic interference and excessive temperature rise, and thus solving the difficulty of stable and clear X-ray imaging. Experimental tests show that the transformer and voltage multiplier circuit device has less interference, better heat dissipation, and lower cost when housed in an insulating casing.

[0017] In the diagram: 1. Square inner cavity, 2. Circular end, 3. Circuit board groove, 4. Groove, 5. Terminal. Detailed Implementation

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] like Figure 1 As shown, this utility model discloses a micro-focus X-ray power supply insulating housing, including a square inner cavity 1. The square inner cavity 1 is a rectangular cavity made of insulating material, used to house the transformer and back pressure circuit board integration. This design uses an epoxy resin casting with a wall thickness of 2-5 mm. The upper part of the cavity is open, and there are four vertical walls on the sides. Two of the symmetrical vertical walls are designed with circuit board grooves 3. The function of the circuit board grooves 3 is to place and limit the circuit board in the inner cavity. The bottom is closed, and a terminal 5 is pre-embedded in the middle of the bottom. The high voltage generated by the circuit board and transformer is output to the device through the terminal 5. The outer side of the bottom is a circular end 2. The wall thickness of the circular end 2 is the same as that of the square inner cavity 1. The end of the circular end is tapered inward to facilitate casting and removal from the mold. Its height is moderate. In this design, the height is about 30 mm. The function of the circular end is to isolate the high voltage from the surrounding environment and prevent discharge. One side of the outer side of the square inner cavity 1 is a groove 4, which is open from top to bottom, so that the heat generated in the cavity can be carried away by airflow, effectively solving the heat dissipation problem.

[0020] The transformer generates more heat than the voltage multiplier circuit during use. When placing the transformer in the cavity, it should be placed closer to the side of groove 4 to ensure a shorter heat dissipation path and better air circulation.

[0021] Through experiments and practical operation, this solution effectively solves the stability problem of microfocus X-ray high-voltage power supply, greatly reduces ripple, and thus improves the clarity and stability of X-ray images.

[0022] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
