Detailed Description
The feedback device and the single-pole double-throw rf coaxial switch according to the present invention will be described and explained in further detail with reference to the accompanying drawings and embodiments.
Embodiment 1 the feedback device of this embodiment has a structure as shown in fig. 1 and 2, and mainly includes a dome assembly 1, a feedback base 2, and a dome base 3. The elastic sheet assemblies 1 are arranged in two groups, are symmetrically arranged on the elastic sheet base 3 and are integrated with the elastic sheet base 3 into a whole through an injection molding process. The elastic sheet assembly 1 comprises a first feedback elastic sheet 4 and a second feedback elastic sheet 5. As shown in fig. 5-8, the first feedback spring piece 1 and the second feedback spring piece 5 are made of metal conductive materials and respectively composed of an inclined portion 17, a vertical portion 18 and a horizontal portion 19.
As shown in fig. 2 and 3, the first feedback spring 4 and the second feedback spring 5 are overlapped on the spring base 3, and the first feedback spring 4 is located above the second feedback spring 5. The inclined part, the vertical part and the horizontal part of the first feedback elastic sheet 4 are respectively parallel to the inclined part, the vertical part and the horizontal part of the second feedback elastic sheet 5. A V-shaped bent portion 20 is provided at the end of the horizontal portion 19 of the first feedback spring 4. A certain distance is provided between the bottom of the bending portion 20 and the horizontal portion of the second feedback spring 5, so that the first feedback spring 4 and the second feedback spring 5 are not in contact with each other when not subjected to an external force.
As shown in fig. 2 and 4, a circular hole 9 is formed in the dome base 3. The middle part of feedback base 2 is provided with axle 8, and through the cooperation in axle and hole, shell fragment base 3 is in the same place with feedback base 2 assembly. On both sides of the feedback base 2, a first support pad 6 and a second support pad 7 are provided. The first support pad 6 and the second support pad 7 are used for supporting the first feedback spring plate 4 and the second feedback spring plate 5 respectively. The purpose of setting up first supporting pad 6 and second supporting pad is for first feedback shell fragment 4 and second feedback shell fragment 5 provide the support, avoids first feedback shell fragment 4 and the contact of second feedback shell fragment 5 under non-operating condition.
The working principle of the feedback device and the single-pole double-throw radio frequency coaxial switch is described as follows: when the switch is switched, the armature assembly 16 in the relay system 14 rotates under the action of the magnetic field, one end tilts up, and the other end falls down. The falling end of the armature assembly 16 is acted by the internal structure of the relay system 14, so that the microwave passages corresponding to the lower part are communicated; the tilted end of the armature assembly acts through the internal structure of the relay system 14 to break the corresponding microwave path below. In the single-pole double-throw radio frequency coaxial switch, the actions of the two armature components and the two feedback devices are synchronous, and the action directions are consistent.
Taking one group of elastic sheet assemblies of the feedback device 13 as an example to describe the feedback principle of the feedback device, the method specifically comprises the following steps: the armature assembly 16 rotates and tilts, one end of the tilting moves upwards to jack the second feedback elastic sheet 5, so that the second feedback elastic sheet 5 moves upwards to contact the bottom of the bent part 20 of the first feedback elastic sheet 4, and the second feedback elastic sheet 5 is connected with the first feedback elastic sheet 4, as shown in a position a in fig. 11. The second feedback dome 5 of the other set of dome assemblies is disconnected from the first feedback dome 4, as shown at B in fig. 11. The second feedback elastic piece 5 is communicated with the inclined part 17 at the upper part of the first feedback elastic piece 4 and the circuit board 12 above the second feedback elastic piece, a circuit communicated with the circuit board 12 is connected with two pins of the control interface 11, the two feedback elastic pieces are respectively communicated with the two pins, and at the moment, a microwave path corresponding to the lower part of the tilting end of the armature component 16 is disconnected, as shown in a part C in fig. 11; the corresponding microwave path below the end where the armature assembly falls communicates as shown at D in fig. 11. Therefore, the communication between the second feedback spring 5 and the first feedback spring 4 is converted into the communication between the two pins of the control interface, so that the communication between the microwave channels of the single-pole double-throw radio frequency coaxial switch can be judged by judging the communication between the two pins in the control interface. The armature assembly 16 rotates and falls, and the falling end moves downwards, so that the second feedback elastic sheet 5 moves downwards, and the second feedback elastic sheet 5 returns to the initial position and is disconnected from the first feedback elastic sheet 4. Therefore, the two pins connected with the second feedback spring 5 and the first feedback spring 4 on the control interface 11 are disconnected. At this time, the microwave path corresponding to the lower side of the dropped one end is reconnected, and the microwave path corresponding to the lower side of the other end is disconnected.
It should be noted that no matter which end of the armature assembly is tilted, two metal elastic pieces of one group of elastic piece assemblies on the feedback device can be contacted, so that two pins of the control interface are communicated, and one of two microwave paths below the armature assembly is communicated.
However, two ends of the armature assembly are in a switched gap, that is, one end of the armature assembly falls down to separate two metal elastic pieces of one group of elastic piece assemblies, but in the process that the other end of the armature assembly is tilted and does not jack up and contact two metal elastic pieces of the other group of elastic piece assemblies, the two metal elastic pieces of the two groups of elastic piece assemblies of the feedback device are both disconnected, at this moment, two pins in the control interface cannot be communicated, and meanwhile, a microwave path below the armature assembly cannot be communicated.
The two-way microwave signal transmission switching function of the single-pole double-throw radio frequency coaxial switch is realized by controlling the connection and disconnection of the two pins of the interface.
The connection and disconnection of the microwave channel can be fed back through the connection and disconnection between the two feedback spring plates of the feedback device. And according to the intercommunication and the disconnection of two sets of shell fragment subassemblies, can judge which way microwave access communicates, which way microwave access disconnection.
