The purpose of this utility model is achieved through the following technical solutions:
The surface-adhered type microwave circulator of novel port organization, comprise housing and cover plate, described housing is half open cylindrical cavity body structure, the sidewall of housing is provided with three port slotted eyes, be respectively equipped with boss on the housing sidewall with on three corresponding positions of port slotted eye, in half open cylindrical cavity of housing, be placed with permanent magnet, even magnetic conducting strip, ferrite, center conductor and temperature-compensating sheet, cover plate is stamped at the top of housing, the port slotted eye that described center conductor passes housing sidewall stretches out outside the chamber, characteristics are: three boss of described housing sidewall all have through hole, port pin pin insulator all is installed in each through hole, the port pin pin of packing in each port pin pin insulator, three port pin pin and center conductor are electrically connected.
Further, the surface-adhered type microwave circulator of above-mentioned novel port organization, wherein, described three port pin pin and center conductor are welded to connect fixing.
Further, the surface-adhered type microwave circulator of above-mentioned novel port organization, wherein, the through hole on described port pin pin insulator and the boss is an interference fit.
Further, the surface-adhered type microwave circulator of above-mentioned novel port organization, wherein, described port pin pin and port pin pin insulator are interference fit.
Again further, the surface-adhered type microwave circulator of above-mentioned novel port organization, wherein, the material of described port pin pin insulator is a polytetrafluoroethylene.
The substantive distinguishing features of technical solutions of the utility model and progressive being mainly reflected in:
1. design a boss in the port of housing, with housing be whole, and drill through the hole at boss, in through hole, load onto port pin pin insulator, port pin pin is installed in the port pin pin insulator, center conductor welds with port pin pin, realizes being electrically connected; Because the through hole of port pin pin insulator and boss adopts interference fit, port pin pin and port pin pin insulator also adopt interference fit, and center conductor and the welding of port pin pin are so the location of port pin pin is quite accurately with stable;
2. after the device in the shell cavity is located by anchor clamps, add respectively in the housing, weld and debug, technology is easy;
3. encapsulating structure of the present utility model makes the reliability of microwave circulator obviously improve on the basis that does not change device performance, and solder yield obviously improves; Have that volume is little, performance is excellent, bear advantages such as power is big, temperature range is wide, be applicable to the large-scale production of circulator.
