Description

Technical Field

[0001] This utility model relates to the field of double-pole double-throw switch technology, specifically a high-power radio frequency control switch. Background Technology

[0002] Digital amplitude modulation (DAM) transmitters are characterized by their small size, high overall efficiency (over 86%), excellent electroacoustic performance (reaching Class A), high reliability, long transistor amplifier lifespan, high operational flexibility, high degree of automation, and simple operation.

[0003] Radio frequency control switches are devices installed in transmitter combiners to perform power combining or automatic switching. They enable transmitter switching when a single-unit system fails.

[0004] When an RF control switch is in operation, it needs to be in contact with current for a long time. However, when the current is large for a long time, a lot of heat will be gradually generated, which will cause the switch to overload and damage the internal components of the switch.

[0005] Therefore, a high-power radio frequency control switch is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

At the same time, the inclined arrangement of the conductive blocks allows the rotation angle of the blades to be used during blade rotation, thereby increasing the contact area of ​​the blades entering the interior of the copper sheets, making the contact area larger and thus reducing resistance, thereby reducing the heat generated during operation.

[0008] Preferably, a protective shell is slidably fitted on the top of the conductive block; the protective shell and the conductive block are correspondingly arranged; by adding the protective shell, the copper sheet can be closed off during daily use, reducing the amount of dust around it falling onto the blade surface, thereby reducing the excessive friction caused by dust when the blade and the copper sheet come into contact.

[0009] Preferably, a slider is slidably connected inside the mounting bracket; a connecting bracket is fixedly connected to the bottom of the slider; the bottom of the connecting bracket is sloped; a pair of spring telescopic rods are fixedly connected to the top of the connecting bracket; the ends of the spring telescopic rods are fixedly connected to the mounting bracket; a push rod is fixedly connected to the side wall of the drive plate; the end of the push rod is sloped; the push rod and the connecting bracket are correspondingly arranged; by adding a slider, when the drive plate drives the blade to rotate, it can drive the push rod to push the connecting bracket, thereby pushing the slider up, thus increasing the position reference of the blade after movement, so as to quickly determine the position of the blade.

[0010] Preferably, an indicator block is fixed to the top of the slider; the indicator block and the slider are set correspondingly; by adding the indicator block, the slider can be quickly observed through the bright color of the indicator block when the slider is observed from a distance.

[0011] Preferably, the end of the push rod is rotatably connected to a roller; multiple rollers are provided on the push rod; by adding rollers, friction can be reduced when the push rod and the connecting frame come into contact, thereby accelerating the movement speed during contact.

[0012] Preferably, a cover plate is rotatably connected inside the mounting bracket; the cover plate is located above the slider; the cover plate and the mounting bracket are connected by a torsion spring; by adding the cover plate, the marking block can be covered when the slider is not in use, thereby increasing the convenience of observation and making the observation more accurate.

[0013] The advantages of this utility model are:

[0014] 1. The high-power radio frequency control switch of this utility model can increase the current carrying capacity between the blades and the copper sheet by adding multiple blades. At the same time, the inclined setting of the conductive block can use the rotation angle of the blades to increase the contact area of ​​the blades into the copper sheet, thereby increasing the contact area and reducing the resistance, thereby reducing the heat generated during operation.

[0015] 2. The high-power radio frequency control switch described in this utility model can close the copper foil during daily use by adding a protective shell, thereby reducing the amount of dust around it falling onto the blade surface and reducing the excessive friction caused by dust when the blade and copper foil come into contact.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] Specific implementation examples are given below.

[0025] like Figures 1 to 5As shown in the embodiment of this utility model, a high-power radio frequency control switch includes a mounting base 1, inside which a drive assembly 11 is installed; a support frame 12 is fixedly connected to the top of the mounting base 1; a round rod 13 is rotatably connected to the middle of the support frame 12; the round rod 13 and the drive assembly 11 are fixedly connected; a mounting bracket 18 is fixedly connected to the top of the support frame 12; multiple conductive blocks 16 are fixedly connected to the end of the mounting bracket 18; the conductive blocks 16 are inclined; multiple copper foils 17 are fixedly connected to the middle of the conductive blocks 16; a drive plate 14 is fixedly connected to the top of the round rod 13; multiple blades 15 are fixedly connected to the end of the drive plate 14; during operation, the transmitter inside the drive assembly 11 first passes through the control board according to the program. The extension and retraction of the DC motor drives the drive plate 14 to rotate, causing the two blades 15 to approach the copper sheet 17 according to preset requirements and connect with the copper sheet 17 inside the conductive block 16. After the blades 15 are in complete contact with the copper sheet 17, the drive assembly 11 receives the position status signal and stops rotating. When not in use, the blades 15 can be moved to the cavity between the two copper sheets 17. By adding multiple blades 15, the current carrying capacity between the blades 15 and the copper sheet 17 can be increased. At the same time, the tilting setting of the conductive block 16 can use the rotation angle of the blades 15 to increase the contact area of ​​the blades 15 into the copper sheet 17, thereby increasing the contact area and reducing the resistance, thus reducing the heat generated during operation.

[0026] like Figures 1 to 5 As shown, a protective shell 2 is slidably fitted on the top of the conductive block 16; the protective shell 2 and the conductive block 16 are correspondingly arranged; during operation, after the entire assembly is placed, a pair of protective shells 2 can be moved down along the top of the copper sheet 17, so that they gradually come into contact with the copper sheet 17, thereby covering the top of the copper sheet 17 and closing it, thus blocking falling impurities and dust from the blade 15 and the copper sheet 17 during use; by adding the protective shell 2, the copper sheet 17 can be closed by the protective shell 2 during daily use, reducing the amount of dust around it falling onto the surface of the blade 15, thereby reducing the excessive friction caused by dust when the blade 15 and the copper sheet 17 come into contact.

[0027] like Figures 1 to 3As shown, a slider 3 is slidably connected inside the mounting bracket 18; a connecting bracket 31 is fixedly connected to the bottom of the slider 3; the bottom of the connecting bracket 31 is sloped; a pair of spring telescopic rods 32 are fixedly connected to the top of the connecting bracket 31; the ends of the spring telescopic rods 32 are fixedly connected to the mounting bracket 18; a push rod 33 is fixedly connected to the side wall of the drive plate 14; the end of the push rod 33 is sloped; the push rod 33 and the connecting bracket 31 are correspondingly arranged; during operation, when the drive plate 14 rotates, it will drive the push rod 33 to move, and the push rod 33 will move closer to the connecting bracket 31. The slider 3 will gradually contact the bottom, thus pushing the connecting frame 31. After being pushed, the connecting frame 31 will gradually move upward. During the movement, the spring telescopic rod 32 will gradually compress. When the slider 3 is lifted, it will gradually protrude into the mounting frame 18. The position of the blade 15 can be determined by whether the slider 3 protrudes. By adding the slider 3, when the drive plate 14 drives the blade 15 to rotate, it can drive the push rod 33 to push the connecting frame 31. When pushed, the slider 3 will be lifted, thus increasing the position reference of the blade 15 after it moves, so that the position of the blade 15 can be quickly determined.

[0028] like Figures 3 to 4 As shown, a marker block 4 is fixedly attached to the top of the slider 3; the marker block 4 and the slider 3 are set accordingly; during operation, when the slider 3 is exposed, the marker block 4 will rise together with it. Since the marker block 4 is brightly colored, it is more conspicuous when observing the slider 3; by adding the marker block 4, the slider 3 can be quickly observed to be prominent through the bright color of the marker block 4 even when the distance is slightly far.

[0029] like Figure 3 As shown, a roller 5 is rotatably connected to the end of the push rod 33; multiple rollers 5 are provided on the push rod 33; during operation, when the push rod 33 pushes the connecting frame 31, the connecting frame 31 will contact the roller 5 as it moves along the push rod 33. When in contact, the roller 5 will rotate together, which will accelerate the movement speed of the connecting frame 31 on the push rod 33, making it move quickly; by adding rollers 5, the friction at the time of contact between the push rod 33 and the connecting frame 31 can be reduced, thereby accelerating the movement speed at the time of contact.

[0030] like Figures 3 to 4As shown, a cover plate 6 is rotatably connected inside the mounting bracket 18; the cover plate 6 is located above the slider 3; the cover plate 6 and the mounting bracket 18 are connected by a torsion spring; during operation, when the slider 3 gradually rises, it will contact the cover plate 6, and after contact, it will gradually lift the cover plate 6. After being lifted, the cover plate 6 will rotate, thereby exposing the slider 3 inside the mounting bracket 18. When the slider 3 is pulled down by the spring telescopic rod 32 returning to its original position, the cover plate 6 will return to its original position due to the force of the torsion spring, closing the top of the slider 3, thereby covering the slider 3; by adding the cover plate 6, the marking block 4 can be covered when the slider 3 is not in use, thereby increasing the convenience of observation and making the observation more accurate.

[0031] Working principle: During use, the transmitter inside the drive assembly 11 controls the extension and retraction of the DC motor via the control board according to the program. The motor drives the drive plate 14 to rotate, causing the two blades 15 to approach the copper sheet 17 according to the preset requirements and connect with the copper sheet 17 inside the conductive block 16. After the blades 15 are in complete contact with the copper sheet 17, the drive assembly 11 receives the position status signal and stops rotating. When not in use, the blades 15 can be moved to the cavity between the two copper sheets 17. After the whole assembly is placed, a pair of protective shells 2 can be moved down along the top of the copper sheet 17, gradually contacting the copper sheet 17, thus covering the top of the copper sheet 17 and closing it. This prevents falling impurities and dust from the blades 15 and copper sheet 17 during use. When the drive plate 14 rotates, it drives the push rod 33 to move. When the push rod 33 approaches the connecting frame 31, it gradually contacts the bottom, thus pushing the connecting frame 31. After pushing, the connecting frame 31... The slider 3 will gradually move upwards. During this movement, the spring telescopic rod 32 will gradually compress. When the slider 3 is lifted, it will gradually protrude into the mounting bracket 18. The position of the blade 15 can be determined by whether the slider 3 protrudes. When the slider 3 is exposed, the indicator block 4 will rise along with it. Since the color of the indicator block 4 is bright, it is more conspicuous when observing the slider 3. When the push rod 33 pushes the connecting bracket 31, the connecting bracket 31 will contact the roller 5 as it moves along the push rod 33. When it contacts the roller 5, it will drive the roller 5 to rotate together. When it rotates, it will accelerate the movement speed of the connecting bracket 31 on the push rod 33, making it move quickly. When the slider 3 gradually rises, it will contact the cover plate 6. After contact, it will gradually lift the cover plate 6. After being lifted, the cover plate 6 will rotate, thus exposing the slider 3 into the mounting bracket 18. When the slider 3 is pulled down by the spring telescopic rod 32 returning to its original position, the cover plate 6 will return to its original position due to the force of the torsion spring, closing the top of the slider 3, thus blocking the slider 3.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
