Description

Technical Field

[0001] This utility model relates to the field of microwave device electrical assembly technology, specifically to a coupler tooling fixture. Background Technology

[0002] Cryogenic couplers employ a low-loss circuit dielectric microstrip press-fit parallel-coupled stripline microstrip circuit configuration. The key is controlling the bonding degree between the two microstrip dielectrics to ensure the device's performance specifications in low-temperature environments. Current assembly processes typically involve manually placing the two microstrip circuits sequentially into the lower cavity of the coupler, then securing the upper and lower cavities with hexagonal screws. This assembly method makes the bonding degree between the two microstrips uncontrollable; even small errors can lead to significant deviations in the coupler's signal transmission. Furthermore, manual screwing requires one hand to screw while the other hand is used for positioning the upper and lower cavities, which greatly affects assembly precision.

[0003] Based on this, in order to address the above-mentioned shortcomings, this application proposes a coupler tooling fixture. Utility Model Content

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Reference Figure 1 , Figure 2 and Figure 3 A coupler tooling fixture includes a frame 1, an air source processor 2, a cylinder 3, a pressure plate 4, a solenoid valve 5, a positioning chamber 6, a pressure sensor 7, a switch button 8, a power socket 9, a fixing cover plate 11, a base plate 12, a side panel 13, a front panel 14, a rear panel 15, and a cylinder mounting plate 16.

[0027] The side panel 13 is provided in two sets, forming an "L" shape. The two sets of side panels 13 are detachably installed between the top of the vertical ends via a cylinder mounting plate 16, which can be achieved by screws or pins.

[0028] The two side panels 13 are connected at the top by a fixed cover plate 11 and at the bottom by a base plate 12. The front ends of the two side panels 13 are connected by a front panel 14 and the rear ends are connected by a rear panel 15, thus forming a frame 1 with a cavity at the bottom, in which a solenoid valve 5 is installed. A switch button 8 is installed on the front panel 14. Two through holes are opened on the rear panel 15, one through hole for installing a power socket 9 and the other through hole for air pipe passage. Considering the overall lightweight and sturdiness, the frame 1 is made of aluminum alloy plate.

[0029] Reference Figure 1 and Figure 3 The air source processor 2 is externally mounted on the side panel 13 of the frame 1 with screws. The air source processor 2 and the cylinder 3 are connected by an air pipe. The cylinder 3 is fixed to the center of the cylinder mounting plate 16 with screws. The solenoid valve 5 is fixed to the bottom plate 12 of the frame 1 with screws. The solenoid valve 5 is connected to the air source processor 2 through an air pipe. The switch button 8 is fixed on the front panel 14 of the frame 1. The positioning cavity 6 is fixed to the fixing cover plate 11 with screws.

[0030] Reference Figure 1 A pressure plate 4 is detachably installed at the bottom output end of cylinder 3. The pressure plate 4 is made detachable so that it can be easily replaced to adapt to the size of the corresponding coupler.

[0031] Specifically, the pressure plate 4 has a screw hole in the middle and through holes at the four corners. The screw hole in the middle is used to connect to the cylinder column with countersunk screws, and the position of the through holes corresponds to the position of the coupler mounting screw holes. To ensure the hardness and wear resistance of the pressure plate 4 and to protect the coupler, polytetrafluoroethylene (PTFE) material is used.

[0032] Reference Figure 1 A positioning cavity 6 is installed on the horizontal working surface of the frame 1. The positioning cavity 6 has a rectangular frame structure. A recessed cavity for installing the coupler is set in the middle of the positioning cavity 6. The size of the recessed cavity is tightly matched with the size of the coupler to be assembled, which is used to position the coupler. A groove is set in the recessed cavity, and a pressure sensor 7 is installed in the groove. The depth of the groove is the same as the thickness of the pressure sensor 7, which can ensure that the bottom of the recessed cavity is flat. A long groove for the circuit of the pressure sensor 7 is reserved on the bottom surface of the recessed cavity.

[0033] The specific operating principle of this application is as follows:

[0034] During assembly, the lower cavity of the coupler, printed circuit board a, printed circuit board b, and upper cavity are placed into the positioning cavity 6 in sequence. The pressure control knob of the air source processor 2 is adjusted to control the downward pressure, and then the throttle valve knob on the cylinder 3 is adjusted to control the downward speed of the cylinder rod. After setting, the pressure switch button 8 is pressed, and the cylinder rod drives the pressure plate 4 to start pressing down. The pressure sensor displays the pressure value N1.

[0035] Use a torque screwdriver to tighten the coupler's upper and lower cavities through the four through holes on the pressure plate 4. Then press the switch button 8 to return the pressure plate 4 to its initial position and remove the coupler.

[0036] After installing the SMA connector on the coupler, use a vector network analyzer to test the coupler's coupling degree and other indicators. If they do not meet the requirements, readjust the pressure control knob of the air source processor 2 and the throttle valve knob on the regulating cylinder 3, and record the pressure sensor value N. Continue this process until the coupler performance test is passed, then solidify the pressing pressure and pressing speed to achieve stable mass production.

[0037] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
