Description

Novel surface mount-type microwave isolator
Technical field
The utility model relates to a kind of novel surface mount-type microwave isolator, belongs to wireless communication technology field.
Background technology
At present, both at home and abroad the surface mount microwave isolator of producing generally all adopts the input and output pin of " gull wing " form, and its structure prolongs also in addition by center conductor " Y " type arm that the bending of " L " type forms.Though the input/output port of this type is simple, but center conductor thickness is 0.127~0.254 millimeter usually, the non-constant of intensity, and the pin overall length dimension is between 7~10 millimeters, size and dimension is easy to change in production and transportation, so not only influence tested service behaviour, also can cause in the dislocation of production line upper surface isolator, rosin joint, the weldering of end user's product and not go up defectives such as housing and circuit board failure welding.In order to keep port sizes and shape invariance shape, on producing, need special forming jig and cutting clamper, and make production efficiency low, need special packing box in transit and cost is increased.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists, and a kind of novel surface mount-type microwave isolator is provided.
The purpose of this utility model is achieved through the following technical solutions:
Novel surface mount-type microwave isolator comprises housing and cover plate, and characteristics are: described housing is formed with half open cylindrical cavity, and the sidewall of housing has port, and position male relative with port on housing sidewall is provided with boss, has through hole on the boss; In half open cylindrical cavity of housing, place permanent magnet, even magnetic conducting strip, ferrite, center conductor and temperature-compensating sheet, and be stamped cover plate, and the port that center conductor passes on the housing sidewall stretches out outside the chamber; Port pin insulator is installed in the through hole of housing sidewall boss, and the port pin is packed in the port pin insulator, port pin and center conductor electric connection.
Further, above-mentioned novel surface mount-type microwave isolator, described port pin and center conductor welding.
Further, above-mentioned novel surface mount-type microwave isolator, the material of described port pin insulator is a polytetrafluoroethylene.
Further, above-mentioned novel surface mount-type microwave isolator, the through hole of described port pin insulator and housing sidewall boss is an interference fit.
Again further, above-mentioned novel surface mount-type microwave isolator, described port pin and port pin insulator are interference fit.
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 bore a hole at boss, in the hole, load onto port pin insulator, the port pin is installed in the port pin insulator, center conductor again with the welding of port pin, realize being electrically connected; Because the through hole of port pin insulator and boss adopts mechanical tight fit, port pin and port pin insulator also adopt mechanical tight fit, and center conductor and the welding of port pin are so the size of port pin and position are quite firmly with stable;
2. after the device in the shell cavity is located by anchor clamps, add respectively in the housing, weld and debug; The technology practicality is a design newly;
3. encapsulating structure of the present utility model makes the reliability of microwave isolator 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 isolator.

Embodiment
As shown in Figure 1 and Figure 2, novel surface mount-type microwave isolator, comprise housing 10 and cover plate 1, housing 10 is formed with half open cylindrical cavity, the left and right sides sidewall of housing 10 all has port, the position male relative with port is provided with boss on housing 10 sidewalls, about each one, have through hole on the boss; In half open cylindrical cavity of housing 10, place permanent magnet 9, even magnetic conducting strip 8, ferrite 7, center conductor 6, ferrite 5, even magnetic conducting strip 4, permanent magnet 3 and temperature-compensating sheet 2, and be stamped cover plate 1, and the port that center conductor 6 passes on housing 1 sidewall stretches out outside the chamber; Port pin insulator 11 is installed in the through hole of housing 10 sidewall boss, the material of port pin insulator 11 is a polytetrafluoroethylene, port pin insulator 11 is an interference fit with the through hole of housing 10 sidewall boss, port pin 12 is packed in the port pin insulator 11, port pin 12 is an interference fit with port pin insulator 11, port pin 12 makes its electric connection with center conductor 6 by welding, forms pad 13.The cross section of port pin 12 is rounded or square, and impedance is 50 ohm (radiofrequency signals relatively).
During concrete the assembling: in the aperture of the housing port boss of earlier port pin insulator 11 being packed into, again port pin 12 is packed in the aperture of port pin insulator 11, then permanent magnet 9, even magnetic conducting strip 8, ferrite 7, center conductor 6, ferrite 5, even magnetic conducting strip 4, permanent magnet 3 and temperature-compensating sheet 2 are packed in order in the housing 10, tighten cover plate 1; At last, port pin 12 and center conductor 6 weld together.
