The utility model discloses a cavity is made by stamping process, simultaneously, the utility model discloses a base also is made by stamping process, thereby makes the utility model discloses a manufacturing cost greatly reduced.
Description
Technical field
The utility model relates to a kind of circulator and isolator, is specifically related to the shell of a kind of circulator and isolator.
Background technology
Circulator is to enter the incident wave of its arbitrary port, imports the multiport device of next port according to the direction order of being determined by quiet bias field into.Its controls electromagnetic wave along a certain belt direction transmission, reverse be obstructed.Circulator has branch's transmission system of characteristics of non-reciprocity, and conventional ferrite circulator is Y shape junction circulator, and it is to be made up of three symmetrical branch lines in angle that are mutually 120 °.The principle of its one-way transmission is owing to having adopted ferrite gyromagnetic material.This material adds under high frequency wave field and the acting in conjunction of Constant Direct Current magnetic field outside, produces gyromagnet characteristic (claiming again tensor permeability characteristic).This gyromagnet characteristic just, makes the electromagnetic wave of propagating in ferrite that the rotation (Faraday effect) polarizing occur, and electromagnetic wave energy strong absorption (ferromagnetic resonance), utilizes just this gyromagnet phenomenon, makes junction circulator, circulator.The features such as it has that volume is little, bandwidth, Insertion Loss are little, thereby application is very extensive.
It is one-way transmission higher frequency signal energy that circulator is again the outstanding feature of isolator.The characteristic of this one-way transmission higher frequency signal energy, is used between the output and load of high frequency power amplifier, plays separately independently, mutually the effect of " isolation ".Load impedance is changing even open circuit or is not affecting the operating state of power amplifier short circuit in the situation that, thereby has protected power amplifier.
Circulator and isolator are class Microwave Iron Oxide Elements, by the transmission of ferrite control microwave signal.Because it has nonreciprocity, forward Insertion Loss is very little, and oppositely time, the energy overwhelming majority is absorbed.Circulator and isolator rely on magnetic field to complete the work of nonreciprocity, but only have magnetic field and there is no microwave ferrite, and the transmission of microwave signal still can reciprocity.Microwave ferrite in device has determined its resonance frequency.
As shown in Figure 1, circulator and isolator in prior art, its shell is made up of base (D1), sidewall (D2) and top cover (D3), described base (D1) is integral type with sidewall (D2), described sidewall (D2) is polygon, described top cover (D3) is fixed in sidewall (D2) by screw thread, and the shell of this kind of circulator and isolator need obtain by mach mode, thereby causes its manufacturing cost higher.
Therefore, we need a kind of manufacturing cost lower, the shell of circulator and isolator.
Summary of the invention
The purpose of this utility model is will solve in above-mentioned prior art, the shell of circulator and isolator, and the problem that manufacturing cost is higher, provides the novel housing that a kind of production cost is lower.
For achieving the above object, the technical scheme that the utility model adopts is as follows:
The shell of a kind of circulator and isolator, formed by base, cavity and top cover, described cavity is fixed in base, described top cover is fixed in cavity by screw thread, it is characterized in that: described base and cavity are split-type structural, described cavity is made up of columnar sidewall and circular base plate, and described sidewall and base plate are integral type structure.
Described sidewall is provided with three breach, and three breach are uniformly distributed circumferentially, the rectangular setting of described breach.
Described base plate is provided with equally distributed installation foot, and the quantity of described installation foot is three.
Described base is provided with installing hole at the installation foot place of corresponding base plate, can embed installation foot, by the mating reaction of installing hole and installation foot, realizes the affixed of cavity and base.
Compared with prior art, the utility model has the advantage of: cavity of the present utility model is made up of columnar sidewall and circular bottom plate, described sidewall and base plate are integral type structure, thereby cavity of the present utility model can be manufactured by punch machining process, simultaneously, base of the present utility model is also to be made by punch machining process, thereby manufacturing cost of the present utility model is reduced greatly.

Fig. 2 is the use state explosion schematic diagram of the utility model embodiment;
Fig. 3 is the overall structure exploded perspective view of the utility model embodiment;
Fig. 4 is the schematic top plan view of base in Fig. 3.
Embodiment
Below in conjunction with accompanying drawing, introduce in detail a kind of embodiment of the present utility model.
As shown in Figures 2 and 3, the shell of the utility model embodiment circulator and isolator, is made up of base 1, cavity 2 and top cover 3, and cavity 2 is fixed in base 1, and top cover 3 is fixed in cavity 2 by screw thread.Base 1 is split-type structural with cavity 2.Cavity 2 is made up of columnar sidewall 21 and circular base plate 22, and sidewall 21 and base plate 22 are integral type structure, and this kind is designed to ensure that cavity 2 can be made by punch machining process.Sidewall 21 is provided with 211, three breach 211 of three breach and is uniformly distributed circumferentially, the rectangular setting of breach 211.Base plate 22 is provided with equally distributed installation foot 221, and the quantity of installation foot 221 is three.As shown in Figure 4, base 1 is provided with installing hole 11 at installation foot 221 places of corresponding base plate 22, and can embed installation foot 221, the mating reaction by installing hole 11 with installation foot 221, realizes the affixed of cavity 2 and base 1.
The cavity 2 of the shell of the utility model circulator and isolator and base 1, adopt punch machining process to make, thus the manufacturing cost of shell of the utility model circulator and isolator reduces greatly.
Below by reference to the accompanying drawings execution mode of the present utility model is explained in detail; but the utility model is not limited to above-mentioned execution mode; in the ken possessing those of ordinary skill in the art; can also under the prerequisite that does not depart from the utility model aim, make various changes and modifications, these changes and improvements all fall in the protection range of the utility model requirement.
