There are no upper or lower limits during the assembly process. The RF component is mainly composed of a cavity cover assembly, a moving switch plate, and an SMA interface. Screws are used to stack and assemble the transmission control part and the RF part. The outer casing covers the transmission control part to protect it and for aesthetic purposes. However, the outer casing has no limiting function and increases the overall weight of the product in the lightweight design. Utility Model Content

[0015] Compared with the prior art, the advantages of this invention are: This invention provides excellent assembly and positioning functionality. The magnet is positioned between the bottom of the upper chuck and the lower inner wall of the first positioning groove, ensuring proper assembly. The magnet's left and right sides are abutted by C-shaped frames, preventing lateral displacement. Another C-shaped frame holds the upper magnetic core between the two C-shaped frames, further preventing lateral movement. Assembly is completed through the cooperation between the upper and lower magnetic cores and the convex positioning holes. This assembly process provides excellent positioning functionality, limiting both vertical and horizontal movement. The second push rod can slide vertically along the inner wall of the second sliding groove, also providing good positioning to prevent lateral deflection during sliding.

[0016] This invention facilitates the switching of high-frequency signals. When the 0V terminal and the second +12V terminal are connected, a strong magnetic force is generated on the upper and lower magnetic core pillars on the left side. This strong magnetic force attracts the top left side of the adsorption block upwards. The adsorption block rotates clockwise around the axis, eventually achieving mutual attraction between the top left side of the adsorption block and the bottom of the lower magnetic core pillar on the left side. During the clockwise rotation of the adsorption block, the push bar also rotates clockwise around the axis. At this time, the bottom right side of the push bar gradually pushes the second push rod on the right side downwards, ultimately causing the first push rod on the right side and the signal connection block to move downwards. At this time, the bottom left and right sides of the signal connection block on the right side are connected to the second SMA interface and the third SMA interface, respectively. When it is necessary to switch high-frequency signals, it is only necessary to connect the 0V terminal and the first +12V terminal, so that the bottom left and right sides of the signal connection block on the left side are connected to the first SMA interface and the second SMA interface, respectively.

[0021] Example: Please see Figure 1-4 An integrally structured snap-fit ​​radio frequency relay, comprising: The overall transmission mechanism 100 specifically includes a top cover 110, a transmission frame 120, and a cavity cover 130. The top cover 110 is fixedly connected to the top of the transmission frame 120, and the cavity cover 130 is fixedly connected to the bottom of the transmission frame 120. In this embodiment, the top cover 110 and the cavity cover 130 can be assembled with the transmission frame 120 by fixing with screws; The electromagnetic mechanism 300 is housed within the overall transmission mechanism 100. The electromagnetic mechanism 300 contains two sets of electromagnet assemblies. Specifically: a second limiting groove 380 is provided at the top of the transmission frame 120; three upper yokes 390 are fixedly connected to the lower inner wall of the second limiting groove 380; a first gap is provided between adjacent upper yokes 390; a first limiting groove 310 is provided within the transmission frame 120, with the upper opening of the first limiting groove 310 flush with the bottom of the upper yokes 390; a magnet 370 is fixedly connected to the center of the lower inner wall of the first limiting groove 310; convex limiting holes 350 are provided on both the left and right sides of the lower inner wall of the first limiting groove 310. Each convex limiting hole 350 consists of an upper hole and a lower hole that are connected vertically, with the diameter of the upper hole being smaller than that of the lower hole. The two sets of electromagnets... The iron components are symmetrically arranged about the magnet 370. Each electromagnet mechanism includes a C-shaped frame 320, an electromagnetic coil 330, an upper magnetic core column 340, and a lower magnetic core column 360. The upper part of the upper magnetic core column 340 is slidably connected to the first gap, and the lower part of the upper magnetic core column 340 is slidably connected to the inner wall of the upper hole of the convex limiting hole 350. The lower magnetic core column 360 is integrally formed at the bottom of the upper magnetic core column 340 and is located in the lower hole of the convex limiting hole 350. There are two C-shaped frames 320, which are respectively attached to the left and right sides of the upper magnetic core column 340. The electromagnetic coil 330 is wound around the two C-shaped frames 320 and generates electromagnetic induction between the upper magnetic core column 340 and the lower magnetic core column 360. In this embodiment: the magnet 370 is positioned between the bottom of the upper chuck 390 and the lower inner wall of the first limiting groove 310, achieving good assembly. The left and right sides of the magnet 370 are abutted by C-shaped frames 320, preventing lateral displacement. Another C-shaped frame 320 holds the upper magnetic core post 340 between the two C-shaped frames 320, preventing lateral movement of the upper magnetic core post 340. Assembly is completed through the mutual cooperation between the upper magnetic core post 340, the lower magnetic core post 360, and the convex limiting hole 350. After assembly through the above steps, it has a good limiting function during assembly, limiting not only its vertical movement but also its lateral movement. It should be noted that the setting of the first gap should be based on the upper magnetic core post... The width of the core post 340 is determined by the specific dimensions of the core post 340, so it will not be described in detail here. When mutual induction occurs between the electromagnetic coil 330, the magnet 370, the upper magnetic core post 340, and the lower magnetic core post 360, a strong magnetic force can be generated, which in turn generates a strong magnetic force on the upper magnetic core post 340 and the lower magnetic core post 360. This cleverly utilizes the principle of electromagnetic induction. It should be noted that the magnitude of the generated strong magnetic force is related to the number of turns of the electromagnetic coil 330 and the magnetic flux of the upper magnetic core post 340 and the lower magnetic core post 360. Therefore, the specific number of turns of the electromagnetic coil 330 and the specifications of the upper magnetic core post 340 and the lower magnetic core post 360 should be set according to the actual situation, so it will not be described in detail here. The snap-fit ​​transmission mechanism 400 is rotatably disposed within the overall transmission mechanism 100. Two sets of electromagnet assemblies drive the snap-fit ​​transmission mechanism 400 to rotate. Specifically, the snap-fit ​​transmission mechanism 400 includes a mounting cavity 410, a rotating shaft 420, a connecting frame 430, an adsorption block 440, and a push bar 450. The mounting cavity 410 is opened within the transmission frame 120. The upper cavity opening of the mounting cavity 410 is flush with the lower opening of the convex limiting hole 350, and the lower cavity opening of the mounting cavity 410 is flush with the top of the cavity cover 130. The rotating shaft 420 is rotatably connected between the front and rear inner walls of the mounting cavity 410, and the rotating shaft 420 is located at the center of the mounting cavity 410. The connecting frame 430 is fixedly connected to the circumferential surface of the rotating shaft 420. The adsorption block 440 is fixedly connected to the top of the connecting frame 430, and the push bar 450 is fixedly connected to the bottom of the connecting frame 430. In this embodiment: the connecting frame 430 can rotate around the rotating shaft 420, thereby realizing the rotation of the adsorption block 440 and the push bar 450. When the upper magnetic core column 340 and the lower magnetic core column 360 on the left side generate a strong magnetic force, the adsorption block 440 rotates clockwise around the rotating shaft 420 through the magnetic adsorption force between the lower magnetic core column 360 and the adsorption block 440, thereby causing the top left side of the adsorption block 440 to attract the bottom of the lower magnetic core column 360 on the left side. When the upper magnetic core column 340 and the lower magnetic core column 360 on the right side generate a strong magnetic force, the adsorption block rotates clockwise around the rotating shaft 420 through the magnetic adsorption force between the lower magnetic core column 360 and the adsorption block 440. 440 rotates counterclockwise around the pivot 420, causing the top right side of the adsorption block 440 to attract each other to the bottom of the lower left magnetic core column 360. It should be noted that when the adsorption block 440 rotates and attracts each other to the lower magnetic core column 360, the left or right end of the adsorption block 440 is in the lower hole of the convex limiting hole 350, achieving good rotational limiting. It should also be noted that the two lower magnetic core columns 360 do not generate strong magnetic force at the same time, which will be described in detail later. Finally, it should be noted that the adsorption block 440 should be made of a material that can be attracted by magnetic force, such as iron, cobalt, nickel, and other magnetic materials. The braking mechanism 900 is mounted on the overall transmission mechanism 100 and is located above the electromagnetic mechanism 300. The braking mechanism 900 drives the strong magnetic force of the two sets of electromagnet assemblies to generate or dissipate. Specifically, the braking mechanism 900 includes a 0V end 910, a first +12V end 920, and a second +12V end 930. The 0V end 910, the first +12V end 920, and the second +12V end 930 are sequentially fixed to the top of the top cover 110 from left to right. All three ends penetrate the top cover 110 and extend into the second limiting groove 380. When the 0V terminal 910, the second +12V terminal 930 and one of the turns of the electromagnetic coil 330 form a circuit, one of the upper magnetic core pillars 340 and the lower magnetic core pillar 360 generate a strong magnetic force. When the 0V terminal 910, the first +12V terminal 920 and another turn of electromagnetic coil 330 form a circuit, another upper magnetic core column 340 and lower magnetic core column 360 generate a strong magnetic force. In this embodiment: when the 0V terminal 910 and the second +12V terminal 930 are connected, a strong magnetic force is generated on the upper magnetic core column 340 and the lower magnetic core column 360 on the left side. When the 0V terminal 910 and the first +12V terminal 920 are connected, a strong magnetic force is generated on the upper magnetic core column 340 and the lower magnetic core column 360 on the right side. It should be noted that how to connect and disconnect the 0V terminal 910 and the second +12V terminal 930, and how to connect and disconnect the 0V terminal 910 and the first +12V terminal 920 are common knowledge to those skilled in the art. For example, they can be started and stopped by a push-button switch or a rotary switch. It should also be noted that when the above settings are made, the 0V terminal 910, the first +12V terminal 920 and the second +12V terminal 930 cannot be connected at the same time. Only by making such a setting can the braking and stopping of the two sets of electromagnet components be achieved separately. The present invention should be set up accordingly based on the above ideas. The pushing mechanism 500 is mounted on the overall transmission mechanism 100 and is located below the snap-action transmission mechanism 400. Two sets of pushing mechanisms 500 are provided. After the snap-action transmission mechanism 400 rotates, it pushes the two sets of pushing mechanisms 500 downwards respectively. Specifically, the two sets of pushing mechanisms 500 are symmetrically arranged about the axis of rotation 420. Each set of pushing mechanisms 500 includes a first slide groove 510, a second slide groove 520, a second push rod 530, a spring 540, a first push rod 550, a sliding hole 560, and a signal connection block 570. The first slide groove 510 is located on the top of the cavity cover 130, and the second slide groove 520 is located on the top of the first slide groove 560. The front inner wall of the groove 510, the second push rod 530 is slidably connected between the left and right inner walls of the second groove 520, the sliding hole 560 is opened in the lower inner wall of the first groove 510, the first push rod 550 is fixedly connected to the bottom of the second push rod 530, and the bottom of the first push rod 550 slides through the sliding hole 560 and extends to the lower side of the cavity cover 130, the signal connection block 570 is fixedly connected to the surface of the first push rod 550, and the signal connection block 570 is located on the lower side of the cavity cover 130, the spring 540 is fixedly connected between the bottom of the second push rod 530 and the lower inner wall of the second groove 520, and the spring 540 is movably sleeved on the surface of the first push rod 550, wherein: When one of the upper magnetic core pillars 340 and the lower magnetic core pillar 360 generates a strong magnetic force, the lower magnetic core pillar 360 attracts and adheres to the top side of the adsorption block 440, and the bottom side of the push bar 450 pushes one of the second push rods 530 downward, and one of the signal connection blocks 570 follows the first push rod 550 downward. The bottom sides of the signal connection block 570 are connected to the first SMA interface 600 and the second SMA interface 700 respectively. When another upper magnetic core post 340 and lower magnetic core post 360 generate a strong magnetic force, the lower magnetic core post 360 attracts and adheres to the other side of the top of the adsorption block 440, and the other side of the bottom of the push bar 450 pushes another second push rod 530 to move downward. Another signal connection block 570 follows the first push rod 550 to move downward. The bottom sides of the signal connection block 570 are connected to the second SMA interface 700 and the third SMA interface 800 respectively. In this embodiment: the second slide groove 520 and the second push rod 530 are necessary. The second push rod 530 can slide up and down along the inner wall of the second slide groove 520, and at the same time has a good limiting function, so that it will not deflect left or right when sliding. The longest width of the second push rod 530 is greater than the width of the first push rod 550. The spring 540 is necessary. Since the second push rod 530 and the first push rod 550 will not directly return to their original position after moving downward, the spring 540 will change from its initial state to a compressed state during the process of pushing the second push rod 530 and the first push rod 550 downward. Therefore, after the push bar 450 disengages from the second push rod 530, it can be reset from the compressed state by the spring 540. The elastic force enables the second push rod 530 and the first push rod 550 to move upward. When the top left side of the adsorption block 440 is attracted to the bottom of the lower left magnetic core column 360, the bottom right side of the push bar 450 will gradually push the second push rod 530 on the right to move downward, thereby enabling the first push rod 550 on the right and the signal connection block 570 to move downward. When the top right side of the adsorption block 440 is attracted to the bottom of the lower right magnetic core column 360, the bottom left side of the push bar 450 will gradually push the second push rod 530 on the left to move downward, thereby enabling the first push rod 550 on the left and the signal connection block 570 to move downward. The first SMA interface 600, the second SMA interface 700, and the third SMA interface 800 are connected to the overall transmission mechanism 100 via a limiting installation mechanism 200. Specifically, the limiting installation mechanism 200 includes a first limiting installation block 210, a second limiting installation block 220, a third limiting installation block 230, and a fourth limiting installation block 240. The fourth limiting installation block 240 and the first limiting installation block 210 are respectively fixedly connected to the left and right sides of the bottom of the cavity cover 130. The first SMA interface 600 and the third SMA interface 800 are fixed to the ends of the fourth limiting mounting block 240 and the first limiting mounting block 210 respectively. The third limiting mounting block 230 and the second limiting mounting block 220 are fixed to the ends of the first SMA interface 600 and the third SMA interface 800 respectively. A second gap is provided between the third limiting mounting block 230 and the second limiting mounting block 220 and the bottom of the cavity cover 130. The second SMA interface 700 is fixedly connected between the third limiting mounting block 230 and the second limiting mounting block 220. When one set of electromagnet components drives the snap-action transmission mechanism 400 to rotate, the snap-action transmission mechanism 400 pushes one set of push mechanisms 500 to move downward, and the push mechanism 500 is connected to the first SMA interface 600 and the second SMA interface 700. When another set of electromagnet components drives the snap-action transmission mechanism 400 to rotate, the snap-action transmission mechanism 400 pushes another set of push mechanism 500 to move downward, and the push mechanism 500 is connected to the second SMA interface 700 and the third SMA interface 800. In this embodiment: when the first push rod 550 and signal connection block 570 on the left move downwards, the signal connection block 570 on the left will eventually connect with the first SMA interface 600 and the second SMA interface 700; when the first push rod 550 and signal connection block 570 on the right move downwards, the signal connection block 570 on the right will eventually connect with the second SMA interface 700 and the third SMA interface 800, thereby realizing the switching of high-frequency signals. It should be noted that the second gap is set to reserve space for the movement of the signal connection block 570. The working principle of this invention is as follows: When the 0V terminal 910 and the second +12V terminal 930 are connected, a strong magnetic force is generated on the upper magnetic core column 340 and the lower magnetic core column 360 located on the left side. This strong magnetic force attracts the top left side of the adsorption block 440 upwards. The adsorption block 440 rotates clockwise around the rotating shaft 420, ultimately achieving mutual attraction between the top left side of the adsorption block 440 and the bottom of the lower magnetic core column 360 located on the left side. During the clockwise rotation of the adsorption block 440, the push bar 450 also rotates clockwise around the rotating shaft 420. At this time, the push bar 450... The bottom right side of the 0 will gradually push the second push rod 530 on the right side downwards, eventually causing the first push rod 550 and the signal connection block 570 on the right side to move downwards. At this time, the left and right sides of the bottom of the signal connection block 570 on the right side are connected to the second SMA interface 700 and the third SMA interface 800, respectively. When it is necessary to switch the high-frequency signal, it is only necessary to connect the 0V terminal and the first +12V terminal, so that the left and right sides of the bottom of the signal connection block 570 on the left side are connected to the first SMA interface 600 and the second SMA interface 700, respectively.

[0022] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concept, should be covered within the scope of protection of the present invention.
