Detailed Description

Referring to fig. 1, 2 and 3, the present utility model provides a high voltage cable connector for an X-ray tube, which can be applied to an X-ray tube, a high voltage generator, etc. to provide a high voltage current. The high voltage cable connector of the X-ray tube may include a flexible socket structure 50 and a plug structure 60, wherein the flexible socket structure 50 may be mounted on the tube housing 10 of the X-ray tube, the plug structure 60 may be detachably connected to the flexible socket structure 50, and an external power source may sequentially pass through the plug structure 60 and the flexible socket structure 50 to provide high voltage current to the X-ray tube.

Referring to fig. 1, in one embodiment of the present utility model, a flexible socket structure 50 may include a seal 51, a flexible socket body 52, and a socket electrode 53. Wherein, the tube shell 10 can be perforated, and the sealing member 51 can be fixed at the perforation of the tube shell 10. The sealing member 51 may be a flange, and the connection between the sealing member 51 and the envelope 10 may be sealed. The flexible socket body 52 may have an opening structure, and an opening end of the flexible socket body 52 may be connected to the inside of the sealing member 51 in a sealing manner, and be located at the opening of the package 10, that is, the opening of the package 10 may be sealed by the sealing member 51 and the flexible socket body 52. The other end of the flexible socket body 52 may be provided with a socket electrode 53. The flexible socket body 52 may be a hollow structure, and the socket electrode 53 may be located on an end of the flexible socket body 52 remote from the package 10. The flexible socket body 52 may be made of a flexible elastic material, for example, rubber.

Referring to fig. 3 and 4, further, since the cooling medium 20 is filled in the tube shell 10, the flexible socket structure 50 can be elastically deformed when the plug structure 60 is not inserted into the flexible socket structure 50. For example, as the ambient temperature at the location of the cartridge 10 increases, the cooling medium 20 begins to expand due to thermal expansion and contraction, at which time the pressure within the cartridge 10 increases and the pressure experienced by the flexible socket structure 50 increases. As the cooling medium 20 expands, the flexible socket body 52 begins to compress until the flexible socket body 52 is squeezed out of the cartridge 10 by the cooling medium 20, at which time the inner surface of the flexible socket body 52 protrudes from the surface of the cartridge 10 and is located outside the cartridge 10. That is, the flexible socket body 52 may be located inside the cartridge 10 when the cooling medium 20 is not expanded, and when the cooling medium 20 is expanded. The flexible socket body 52 is capable of elastic deformation, and the flexible socket body 52 may be gradually compressed and expanded out of the inside of the package 10, at which time the flexible socket body 52 may be located outside of the package 10. The flexible socket body 52 can also play a role in pressure relief during deformation, and prevent damage to the structure of the cartridge 10 and the internal components thereof caused by excessive pressure of the cooling medium 20 in the cartridge 10.

Further, to facilitate elastic deformation of the flexible socket body 52, the overall shape of the flexible socket body 52 may be a shape approximating a pen point. The flexible socket body 52 may include a flexible sealing member 521 and a flexible connection member 522, and the flexible sealing member 521 and the flexible connection member 522 may be made of the same material. The number of the flexible sealing members 521 may be at least one, and the number of the flexible connecting members 522 may be at least one. When the number of the flexible sealing members 521 is one, the flexible connecting member 522 may not be provided, and the whole of the flexible sealing member 521 may have a shape similar to that of a pen point. When the number of the flexible sealing members 521 is plural, adjacent two flexible sealing members 521 are connected by a flexible connection member 522. The outer diameters of adjacent two flexible seals 521 may be different in size, e.g., the outer diameter of the flexible seal 521 that is closer to the seal 51 is larger for different flexible seals 521.

Referring to fig. 2, in one embodiment of the present utility model, the plug structure 60 may include a connection wire 61, a plug body 62, and a plug electrode 53. The connection wire 61 may be fixed to one end of the plug main body 62, and the plug electrode 53 may be fixed to the other end of the plug main body 62. The connection line 61 may be electrically connected to an external power source, and the plug electrode 53 may be electrically connected to the connection line 61, and thus the external power source may transmit a high-voltage current to the plug electrode 53 through the connection line 61. The shape of the plug main body 62 may be adapted to the shape of the flexible socket main body 52, and the plug electrode 53 may be inserted into the flexible socket main body 52. When the plug main body 62 is inserted into the flexible socket main body 52, the outer surface of the plug main body 62 is attached to the inner wall of the flexible socket main body 52, that is, the plug main body 6 is in close contact with the flexible socket main body 52, and no gap exists between the plug main body 6 and the flexible socket main body 52. The plug electrode 53 may be electrically connected to the socket electrode 53. During operation of the X-ray tube, the cooling medium 20 may expand thermally. Because the outer surface of the plug body 62 is attached to the inner wall of the flexible socket body 52, after the plug structure 60 is inserted into the flexible socket structure 50, a pressure buffer device can be disposed in the X-ray tube body, so that the pressure in the X-ray tube body can be ensured to be within a certain range. Therefore, the pressure relief effect can be achieved to a certain extent, and the structure of the X-ray tube can be protected.

Referring to fig. 3, further, after the plug main body 62 is plugged into the flexible socket main body 52, the external power source, the connection wire 61, the plug electrode 63 and the socket electrode 53 can be electrically connected in sequence, at this time, the flexible socket structure 50 can be located inside the package 10, the socket electrode 53 can be electrically connected with the device 30 in the package 10, and the external power source can provide high-voltage current to the device 30 in the package 10 through the connection wire 61, the plug electrode 63 and the socket electrode 53 in sequence. Of course, in order to facilitate the electrical connection of the socket electrode 53 to the device 30, a contact groove 40 may be further provided on the device 30, and the shape of the contact groove 40 may be adapted to the shape of the socket electrode 53, so that the socket electrode 53 can be in contact with the contact groove 40 when the flexible socket body 52 is not elastically deformed. The device 30 may be various electrical components such as a cathode structure, an anode bearing, etc. in the X-ray tube, which need to use high voltage current.

The utility model also provides an X-ray tube, which can comprise an X-ray tube main body and high-voltage cable joints, wherein the number of the high-voltage cable joints can be at least one, the high-voltage cable joints can be arranged on the tube shell 10 of the X-ray tube main body, the specific distribution positions of the high-voltage cable joints can be not limited, and the high-voltage cable joints can be set according to actual requirements.

Therefore, in the above scheme, because the flexible socket structure adopts the flexible elastic structure, under the transportation or storage state of the X-ray tube, the plug structure is not inserted into the flexible socket main body, and when the cooling medium in the X-ray tube expands due to heating, the flexible socket main body can elastically deform and expand out of the tube shell, so that the pressure relief can be effectively carried out inside the tube shell, and then the tube shell and the electric elements inside the tube shell can be protected.
