Description

Technical Field

[0001] The invention relates to the field of microstrip circulators, and in particular to a miniaturized microstrip circulator processing technology and a microstrip circulator. Background Art

[0002] Circulators are an important type of basic device in microwave engineering. They are widely used in various civil and military equipment such as civil communications, microwave measurement, radar, communications, electronic countermeasures, aerospace, etc. In the equipment, they are mainly used to achieve antenna transmission and reception sharing, inter-stage isolation and other issues.

[0003] The following problems exist in the process of processing and working of microstrip circulator:

[0004] 1. During the processing, it is difficult for traditional processing methods to eliminate the influence of gravity and meet the requirements of product testing in a vertical state and use in a weightless environment;

[0005] 2. During operation, the microstrip circulator needs to transmit and receive microwaves, but the transceiver has different microwave transmission and reception effects at different positions, and the transceiver is not easy to adjust, resulting in poor signal transmission and reception effects and low signal transmission and reception efficiency;

[0006] 3. During operation, a large amount of heat is generated inside the microstrip circulator.

[0016] A processing technology for a miniaturized microstrip circulator, the processing steps are as follows:

[0017] S1. Punch holes at places on the ferrite substrate where metallized grounding through holes are required, make vents for heat dissipation and ventilation, and install heat dissipation filters in the vents;

[0018] S2, using the prefabricated circuit coating on the sputtered film layer, and installing the microstrip circuit in the ring;

[0026] 1. In the present invention, the gas valve on the gas transmission pipe is opened, and the gas enters the annular tube, and enters the second regulating chamber of this section through the connecting pipe. The gas pressure causes the piston to move in the opposite direction of the second regulating chamber, so that the telescopic device contracts, the return spring is compressed, and the regulating ball moves, driving the transceiver connected thereto to move. Since the displacement of the transceiver is restricted, the transceiver moves at an angle, so that the transceiver is easy to adjust, thereby improving the effect and efficiency of sending and receiving signals.

[0027] 2. The heat gas generated by the present invention enters the airbag through heat dissipation and is not discharged, thereby reducing the influence of heat dissipation on surrounding components and improving the heat dissipation effect and efficiency.

[0028] 3. The present invention filters the gas through the heat dissipation filter, enters the heat dissipation pipe, is driven by the heat dissipation pump, extracts the gas, and then enters the air bag through the output pipe to dissipate the heat inside the circulator without affecting the surrounding components, thereby improving the heat dissipation efficiency.

[0029] 4. The present invention stores the heat-dissipating gas in the airbag and uses the heat-dissipating gas to adjust the angle of the transceiver while the circulator is working, thereby improving the synchronization of the work.

[0030] 5. In the present invention, since the adjustment cavity is a cross-shaped structure, air can be introduced into different adjustment cavities when adjusting the angle of the transceiver. By adjusting the amount of air introduced, the various angles of the transceiver can be adjusted, so that the transceiver can rotate 360°, thereby improving the effect and efficiency of transmitting and receiving signals.

[0031] 6. The present invention evenly places auxiliary pads under the annulator, and measures and compensates the auxiliary pads in a vertical state to make their flatness meet certain requirements. This plane is used as a machining clamping reference and a rough machining reference to achieve the product's testing in a vertical state and use requirements in a weightless environment.

[0032] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] In the description of the present invention, it should be understood that the terms "upper", "middle", "outer", "inner" and the like indicating directions or positional relationships are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0044] like Figure 1-6 As shown, this embodiment is a miniaturized microstrip circulator, including a covered cuboid 110, an intracavity element 120, a metal connecting portion 130, a ring 140, a microstrip circuit 150, a heat dissipation component 160 and a receiving adjustment component 170;

[0045] A cavity 210 is provided inside the covered rectangular parallelepiped 110, an intra-cavity element 120 is provided inside the cavity 210, a ring 140 is provided around the covered rectangular parallelepiped 110, the ring 140 and the covered rectangular parallelepiped 110 are connected via a plurality of metal connecting parts 130, a microstrip circuit 150 is provided inside the ring 140, a heat dissipation assembly 160 is provided at the bottom of the covered rectangular parallelepiped 110, a receiving adjustment assembly 170 is provided inside the covered rectangular parallelepiped 110, and the receiving adjustment assembly 170 is connected to the heat dissipation assembly 160.

[0046] A base 220 is disposed inside the covered rectangular parallelepiped 110 , and a transceiver 230 is movably disposed on the top of the base 220 .

[0047] The heat dissipation assembly 160 includes a heat dissipation filter 1601, a heat dissipation pipe 1602, an input pipe 1603, a heat dissipation pump 1604, an output pipe 1605 and an air bag 1606. The heat dissipation filter 1601 is arranged at the bottom of the covered rectangular parallelepiped 110, one end of the heat dissipation pipe 1602 is connected to the heat dissipation filter 1601, the other end of the heat dissipation pipe 1602 is connected to the input pipe 1603, the other end of the input pipe 1603 is connected to the input end of the heat dissipation pump 1604, one end of the output pipe 1605 is connected to the output end of the heat dissipation pump 1604, and the other end of the output pipe 1605 is connected to the air bag 1606;

[0048] When working, the gas is filtered through the heat dissipation filter 1601 and enters the heat dissipation pipe 1602. The heat dissipation pump 1604 drives the gas to be extracted and then enters the air bag 1606 through the output pipe 1605 to dissipate the heat inside the circulator without affecting the surrounding components, thereby improving the heat dissipation efficiency.

[0049] During operation, the heat gas generated by heat dissipation enters the air bag 1606 and is not discharged, thereby reducing the influence of heat dissipation on surrounding components and improving the heat dissipation effect and efficiency.

[0050] The receiving adjustment assembly 170 includes a first adjustment chamber 1701, an adjustment ball 1702, a retractor 1703, a return spring 1704, a second adjustment chamber 1705 and a piston 1706. The first adjustment chambers 1701 and the second adjustment chambers 1705 are all arranged inside the base 220. The first adjustment chambers 1701 are connected to the second adjustment chambers 1705. The first adjustment chambers 1701 and the second adjustment chambers 1705 form a cross-shaped structure. The adjustment ball 1702 is movably arranged in the cross-shaped structure. At the center of the structure, a plurality of retractors 1703 are connected to the outer wall of the adjusting ball 1702, and a plurality of retractors 1703 are arranged one by one inside a plurality of first adjusting chambers 1701. A reset spring 1704 is sleeved around the retractors 1703. The second adjusting chamber 1705 is a truncated cone structure. A piston 1706 is connected to the retractor 1703. The piston 1706 is located at the connection between the first adjusting chamber 1701 and the second adjusting chamber 1705. The adjusting ball 1702 is connected to the transceiver 230 through a connecting rod.

[0051] The receiving and regulating component 170 further includes a gas delivery structure 1707, and the heat dissipation component 160 is connected to the receiving and regulating component 170 via the gas delivery structure;

[0052] The gas delivery structure 1707 includes a connecting pipe 310, an annular pipe 320, a control valve 330 and an air delivery pipe 340. The annular pipe 320 is arranged around the base 220. One end of each of the connecting pipes 310 is connected to the annular pipe 320. The other ends of the connecting pipes 310 are connected to the first regulating chambers 1701 in a one-to-one correspondence. The control valves 330 are respectively arranged on the annular pipe 320. One end of each of the air delivery pipes 340 is connected to the airbag 1606. The other ends of the air delivery pipes 340 are connected to the annular pipe 320.

[0053] When working, the gas enters the annular tube 320 through the opening of the gas valve on the gas delivery pipe 340, and enters the second regulating chamber 1705 of this section through the connecting pipe 310. The gas pressure causes the piston 1706 to move in the opposite direction of the second regulating chamber 1705, so that the retractor 1703 contracts, the return spring 1704 is compressed, and the regulating ball 1702 moves, driving the transceiver 230 connected thereto to move. Since the transceiver 230 is restricted in displacement, the transceiver 230 moves at an angle, making it easier to adjust the transceiver 230, thereby improving the effect and efficiency of sending and receiving signals.

[0054] Moreover, since the adjustment cavity is a cross-shaped structure, air can be introduced into different adjustment cavities when adjusting the angle of the transceiver 230. By introducing more or less air, the angles of the transceiver 230 can be adjusted, so that the transceiver 230 can rotate 360 ​​degrees, thereby improving the effect and efficiency of transmitting and receiving signals.

[0055] The gas dissipated by the heat is stored in the airbag 1606, and the angle of the transceiver 230 is adjusted by using the dissipated gas, and the circulator is working at the same time, so as to improve the synchronization of the work;

[0056] Each gas pipeline 340 is controlled by a gas valve so as to input gas into different sections of the annular pipe 320 through different gas pipelines 340 .

[0057] The distances between the control valves 330 are equal, and each control valve 330 is located between two connecting pipes 310 .

[0058] A processing technology for a miniaturized microstrip circulator, the processing steps are as follows:

[0059] S1. Punch holes at places on the ferrite substrate where metallized grounding through holes are required, make vents for heat dissipation and ventilation, and install heat dissipation filters 1601 in the vents;

[0060] S2, using the prefabricated circuit coating on the sputtered film layer, and installing the microstrip circuit 150 in the ring 140;

[0061] S3, welding the covered cuboid 110, the intracavity element 120, the metal connection portion 130, the ring 140, the heat dissipation component 160 and the receiving adjustment component 170 together by soldering;

[0062] S4. The bonded workpiece is placed in a high temperature box for curing, and after curing, the basic structure of the product is formed;

[0063] S5. Evenly glue auxiliary pads to the bottom of the covered cuboid 110 and the ring 140, and vertically hang the annular device on the tooling through two connection points;

[0064] S6. Measure the flatness of the auxiliary pads by using a laser tracker, and compensate the auxiliary pads according to the measurement results to ensure that the coplanarity of all auxiliary pads is less than or equal to 0.15mm;

[0065] S7. Use the auxiliary pad surface as the clamping reference surface and the rough machining reference surface to clamp and process the annular device.

[0066] The laser tracker measured the initial flatness of the active surface and waveguide surface to be 0.57mm and 0.66mm respectively.

[0067] A method for heat dissipation and transceiver adjustment of a miniaturized microstrip circulator comprises the following steps:

[0068] Heat dissipation;

[0069] A plurality of air inlets are provided on the top of the covered cuboid 110. The heat generated in the circulator is filtered through the heat dissipation filter 1601 and enters the heat dissipation pipe 1602. The heat dissipation pump 1604 drives the gas to be pumped out and then enters the air bag 1606 through the output pipe 1605.

[0070] Adjust the transceiver angle;

[0071] When the transceiver angle needs to be adjusted, in order to adjust the direction in which the transceiver needs to move, the air valve on the air pipe 340 in the opposite direction is opened, and the gas enters the annular tube 320, and enters the second regulating chamber 1705 of this section through the connecting tube 310. The air pressure causes the piston 1706 to move in the opposite direction of the second regulating chamber 1705, so that the telescopic device 1703 contracts, the return spring 1704 is compressed, and the regulating ball 1702 moves, driving the transceiver 230 connected thereto to move. Since the transceiver 230 is restricted in displacement, the transceiver 230 moves at an angle.

The preferred embodiments do not describe all the details in detail, nor do they limit the invention to the specific implementation methods described.
