Detailed Description
Example (b):
the embodiments of the present invention will be described in detail below with reference to the accompanying drawings, and it is to be understood that the described embodiments are merely illustrative of some, but not all embodiments of the invention.
In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.
As shown in fig. 1 to 4, a ceramic for magnetron, in which two lead holes 101 are opened in an axial direction of a ceramic body 1, the lead holes 101 penetrating from an outer end surface to an inner end surface of the ceramic body 1 for inserting leads 2; the end surface of the inner side of the ceramic body 1 is provided with a connecting sheet groove for placing a connecting sheet matched with the connecting sheet groove; the outer end face of the ceramic body 1 is further provided with a limiting groove 102 to form positioning limitation on the lead 2 inserted into the lead hole 101. As an insulating and sealing part of a magnetron, the ceramic of the embodiment is used in a cathode component of the magnetron, in the processing process, two leads 2 pass through lead holes 101 of a ceramic body 1 and are introduced into the magnetron, when the ceramic is brazed and sealed with a connecting sheet, the limiting grooves 102 on the ceramic body 1 limit and position the two leads 2, so that mutual limiting between materials is directly realized, the materials cannot rotate and deviate, a clamp is not needed to be additionally used for positioning in the welding process, the use of a magnetron processing and positioning tool is reduced, and the production efficiency and the product quality of the magnetron are improved.
In the embodiment, the lead 2 matched with the ceramic for the magnetron is combined and used to form a novel magnetron lead structure. Referring to the drawings specifically, in this embodiment, the limiting groove 102 of the ceramic body 1 is an elongated limiting groove, which extends outward from the center of the ceramic body 1 and crosses the outer ports of the two lead holes 101, respectively, and the width of the elongated limiting groove is not less than the diameter of the lead holes 101.
