Manufacturing method of center conductor assembly and circulator

Abstract

The invention discloses a manufacturing method of a center conductor assembly and a circulator, and belongs to the technical field of microwave components. The manufacturing method comprises the following steps: mounting the ferrite in the insulation limiting structure; wrapping an insulation limiting structure by an inner conductor structure, wherein the inner conductor structure comprises an inner conductor body and three inductance wires, and the three inductance wires are arranged on the periphery of the inner conductor body at equal intervals in the circumferential direction; sequentially winding the three inductance wires around the upper side of the insulation limiting structure to be woven in a crossed mode to wrap the insulation limiting structure, and limiting the ferrite between the inner conductor body and the three inductance lines; enabling the adjacent inductance wires to be insulated and isolated through the sheet-shaped insulation structures in the process that the three inductance wires are sequentially wound around the upper sides of the insulation limiting structures to be woven in a crossed mode; and limiting the connecting tail ends of the three inductance wires which are woven in a crossed manner to obtain a central conductor assembly. According to the manufacturing method of the center conductor assembly, the attaching degree of the ferrite and the inner conductor body can be improved.

[0002] The circulator is an important part of the microwave system, which ensures the isolation between the transmitting part and the receiving part of the microwave circuit; further, the manufacturing method of the central conductor assembly in the circulator belongs to one of the core parts of the circulator. Some center conductor components are mainly composed of inner conductor, ferrite and insulating film. There are three inductance lines on the inner conductor, and the ferrite is bonded to the inner conductor through the three inductance lines. However, at present, in the manufacture of the center conductor During the assembly process, due to the existing cylindrical structure of the ferrite, the tightness between the ferrite and the inductor wire is insufficient, resulting in insufficient adhesion between the ferrite and the inner conductor body, thereby reducing the performance of the circulator index
