Description

Technical Field

[0001] The invention belongs to the technical field of anti-interference magnetic bead connector protection, in particular to an anti-interference magnetic bead connector and a protection component. Background Art

[0002] Anti-interference magnetic bead connectors, as an important electronic component, play a key role in suppressing high-frequency noise and spike interference in circuit design. Anti-interference magnetic beads, also known as EMI absorption magnetic rings or magnetic beads, work based on the characteristic that impedance changes with frequency. In the low frequency band, the inductive impedance of the magnetic beads is low and has little effect on signal transmission; in the high frequency band, as the frequency increases, the impedance of the magnetic beads gradually increases and gradually shows resistance function. This characteristic enables the magnetic beads to effectively convert high-frequency noise into heat energy consumption, thereby filtering out noise and protecting the stable operation of the circuit.

[0003] In the process of using the existing anti-interference magnetic bead connector, the connector is plugged into the connecting plug to achieve circuit connectivity. However, when the connector is used in equipment in some chemical plants, the process of producing chemical products in the factory will cause corrosive gases to be contained in the factory. At the same time, in order to reduce the spread of these corrosive gases, the general factory will use a spraying method to absorb and settle the corrosive gases, thereby improving the working environment.

[0004] However, spraying water mist will greatly increase the humidity in the factory, which will cause the humid water mist to adhere to the connector or even penetrate into the connector, thereby causing a short circuit in the connector. When a short circuit occurs in the connector, the connector cannot automatically cut off the circuit, causing the current in the connector to increase sharply, causing the connector to melt or even cause a fire, resulting in equipment damage.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. The anti-interference magnetic bead connector and protection component described in the present invention controls the power off of the electrophoretic magnetic column in the fixed box through a temperature sensor. After the power is off, the electrophoretic magnetic column will lose its magnetic force and will not be able to generate suction to the protrusion which is also magnetic. Without the suction of the electrophoretic magnetic column, the first compression spring will be released, pushing the protrusion to squeeze the inclined block. Because the electrophoretic magnetic column will adsorb the protrusion to squeeze the first root when it is energized, the inclined block will be squeezed after the insertion block is squeezed, so that the insertion block drives several connecting rods to disengage from the connecting pins, so that the current passing through the connector is automatically cut off, so that the connector can be protected in time to prevent the connector from being melted or causing greater losses under continuous high current conditions.

[0020] 2. The anti-interference magnetic bead connector and protection component described in the present invention cuts off the power to the electrophoretic magnetic block in the second cavity. The electrophoretic magnetic block will lose its magnetism after the power is cut off. At this time, the third compression spring will release the elastic force, and then push the push block to move toward the card block. In the process of the push block moving toward the card block, the limit block elastically arranged in the card slot on one side will abut against the card block, and then the limit block will retract into the card slot. In the process of the limit block retracting into the card slot, the trapezoidal limit block will squeeze the top plate in the top slot, and then the top plate will extend out of the top slot and will lift up the end of the rotating plate, so that the rotating plate will be separated from the card block, and the contact plug-in block and the positioning frame will be stably plugged in. After the release, the electrophoretic magnetic column in the fixed box will be powered off, and then the plug-in block and the positioning frame will be separated quickly, thereby achieving the effect of protecting the equipment and also protecting the connector. If the connector is subsequently checked and found to be not damaged, it can continue to be used, thereby extending the service life of the connector.

[0021] 3. The anti-interference magnetic bead connector and protection component described in the present invention rotates a plurality of rollers rotatably arranged in a fixed box. After each roller rotates, it will drive the first gear at one end thereof to rotate, and the rotation of the first gear will drive the first strip steel to transmit, and the transmission of the first strip steel can drive the second gear to rotate, and the rotation of the second gear can drive the reciprocating screw to rotate, and then the push plate slidably connected to the circumferential surface of the reciprocating screw will move toward the silicone block, and the initial state is that the push block is in contact with the silicone block. Therefore, when the reciprocating screw drives the push block to move, it can directly squeeze toward the silicone block to squeeze out the moisture in the silicone block, and then the water will flow to the inclined plate on the bottom surface of the fixed box, and be drained by the inclined plate, so as to flow out from the water outlet of the fixed box, thereby ensuring the adsorption effect of the silicone block and improving the adsorption efficiency of the silicone block.

[0039] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0040] Embodiment 1

[0041] like Figures 9 to 11As shown, an anti-interference magnetic bead connector described in an embodiment of the present invention includes a base plate 5, a plug shell 51 is fixedly connected to one side of the base plate 5, a back cover 53 is fixedly connected to one side of the base plate 5, a plurality of terminals 52 are plugged between the plug shell 51 and the back cover 53, a plurality of magnetic rings 54 are fixedly connected to the lower surface of the back cover 53, and the terminals 52 can penetrate the magnetic rings 54 and be plugged into the magnetic rings 54.

[0042] like Figures 1 to 8 As shown, an anti-interference magnetic bead connector and a protection component of an embodiment of the present invention include a fixing plate 1, a positioning frame 14 is fixedly connected to one side of the fixing plate 1, a connecting cavity 12 is provided in the positioning frame 14, a plurality of connecting pins 11 are plugged into the interior of the positioning frame 14, a plurality of connecting pins 11 are plugged into the same plug block 3, a connecting tube 13 is fixedly connected to the position of each plug pin of the plug block 3, and the connecting tube 13 can be plugged and energized with the connecting pin 11; two groups of protective parts are arranged inside the positioning frame 14, and each group of protective parts includes A fixing box 2 is fixedly connected to the inner wall of the positioning frame 14, and a first cavity 21 is opened in the fixing box 2. Two electrophoresis magnetic columns 22 are fixedly connected inside the first cavity 21. A telescopic column 23 is fixedly connected to the middle of the first cavity 21. A first compression spring 24 is sleeved on the circumferential surface of the telescopic column 23. A protrusion 25 is fixedly connected to the top of the first compression spring 24. Two inclined blocks 31 are fixedly connected to the side of the insert block 3 close to the positioning frame 14. The two inclined blocks 31 are both in contact with the corresponding protrusions 25. A temperature sensor 17 is fixedly connected to the inner wall of the positioning frame 14.

[0043] Specifically, in the process of using the existing anti-interference magnetic bead connector, the connector is plugged into the connecting plug to achieve circuit connectivity. However, when the connector is used in equipment in some chemical plants, the process of producing chemical products in the factory will cause corrosive gases to be contained in the factory. At the same time, in order to reduce the diffusion of these corrosive gases, the factory generally uses a spraying method to adsorb and precipitate the corrosive gases, thereby improving the working environment. However, spraying water mist will greatly increase the humidity in the factory, which will cause the humid water mist to adhere to the connector and even penetrate into the connector, thereby causing the connector to short-circuit. When the connector short-circuits, the connector cannot automatically cut off the circuit, causing the current in the connector to increase sharply, so that the connector may melt, or even cause a fire, resulting in equipment damage.

[0044] Therefore, the present invention solves this problem by setting a certain structure. First, when the plug block 3 and the positioning frame 14 are plugged and powered on, the connecting tube 13 of the plug block 3 and the connecting pin 11 in the positioning frame 14 are plugged, and the plugging length is less than the width of the protrusion 25. When the connecting pin 11 inside the connector is short-circuited, the current at the connecting pin 11 will increase sharply, causing the temperature of the connecting pin 11 to rise rapidly. After the temperature of the connecting pin 11 rises, the temperature sensor 17 will monitor the temperature change. When the temperature exceeds the set temperature threshold, the temperature sensor 17 will control the electrophoresis magnetic column 22 in the fixing box 2. When the power is turned off, the electrophoretic magnetic column 22 will lose its magnetic force and will not be able to generate suction force on the convex block 25 which is also magnetic. Without the suction force of the electrophoretic magnetic column 22, the first compression spring 24 will be released, pushing the convex block 25 to squeeze the inclined block 31. Because the electrophoretic magnetic column 22 will absorb the convex block 25 to squeeze the first root when it is powered on, the inclined block 3 will be squeezed after being squeezed, so that the plug block 3 drives several connecting rods to separate from the connecting pin 11, so that the current passing through the connector is automatically cut off, so that the connector can be protected in time to prevent the connector from being melted or causing greater losses under continuous high current conditions;

[0045] The problem that when a short circuit occurs in the connector, the connector cannot automatically cut off the circuit, causing the current in the connector to increase sharply, which may cause the connector to melt, or even cause a fire, resulting in equipment damage, is solved.

[0046] like Figure 2 and Figure 3 As shown, in this embodiment, a plurality of auxiliary rods 15 are fixedly connected to the inner wall of the positioning frame 14 , and an auxiliary frame 16 is fixedly connected to the position of each auxiliary rod 15 of the insert block 3 , and the auxiliary frame 16 is plugged into the auxiliary rod 15 .

[0047] Specifically, during the process of plugging the plug block 3 into the positioning frame 14, a plurality of auxiliary rods 15 are fixedly connected to the inner wall of the positioning frame 14, and then when the plug block 3 is plugged in, a plurality of auxiliary frames 16 fixed on one side thereof will be aligned with the auxiliary rods 15, and then the auxiliary frames 16 and the auxiliary rods 15 are plugged in together, thereby improving the plugging stability of the positioning frame 14 into the plug block 3 and better connecting the connector and the device together.

[0048] like Figure 2 and Figure 3 As shown, the upper surface of the positioning frame 14 of this embodiment is provided with a clamping part, and the clamping part includes a clamping block 34 fixedly connected to the upper surface of the positioning frame 14, and two positioning rods 32 are fixedly connected to the upper surface of the insertion block 3. A rotating plate 33 is rotatably connected between the two positioning rods 32 through a torsion spring, and the cross-section of the rotating plate 33 is "L"-shaped, and the rotating plate 33 can be buckled on the clamping block 34.

[0049] Specifically, after the positioning frame 14 and the plug-in block 3 are plugged together, the rotating plate 33 arranged between the two positioning rods 32 is rotated, and then the rotating plate 33 is engaged with the card block 34 on the positioning frame 14, so that the plug-in block 3 can be prevented from falling off. The plug-in block 3 is generally set on the equipment, and power is supplied or data is transmitted by connecting the plug-in block 3 with the connector.

[0050] like Figure 5 As shown, the upper surface of the positioning frame 14 of this embodiment is fixedly provided with a release member, and the release member is used to release the clamping member. The release member includes a connecting frame 310 fixedly connected to the upper surface of the positioning frame 14, and a second cavity 311 is opened inside the connecting frame 310. Two electrophoretic magnetic blocks 312 are fixedly connected in the second cavity 311. A third compression spring 313 is fixedly connected to the middle of the second cavity 311, and a push block is fixedly connected to the end of the third compression spring 313 away from the connecting frame 310. 314, a slot 315 is provided on one side of the push block 314, a plurality of first springs 316 are fixedly connected in the slot 315, one end of the plurality of first springs 316 is fixedly connected to the same limit block 317, the limit block 317 is trapezoidal, a top slot 318 is provided on the upper surface of the push block 314 corresponding to the limit block 317, a top plate 319 is slidably inserted in the top slot 318, a plurality of second springs 320 are fixedly connected between the top plate 319 and the top wall of the slot 315.

[0051] Specifically, when a short circuit occurs in the connector and the temperature sensor 17 detects an abnormal temperature, the electrophoretic magnetic block 312 in the second cavity 311 is powered off. The electrophoretic magnetic block 312 loses its magnetism after being powered off. At this time, the third compression spring 313 releases its elastic force and pushes the push block 314 to move toward the card block 34. During the movement of the push block 314 toward the card block 34, the elastically arranged limit block 317 in the card slot 315 on one side thereof abuts against the card block 34, and then the limit block 317 retracts into the card slot 315. During the process of the limit block 317 retracting into the card slot 315, In the process, the trapezoidal limit block 317 will squeeze the top plate 319 in the top groove 318, and then the top plate 319 will extend out of the top groove 318, and will lift the end of the rotating plate 33, so that the rotating plate 33 will be separated from the block 34, and the contact plug-in block 3 and the positioning frame 14 will be stably plugged in. After the release, the electrophoresis magnetic column 22 in the fixing box 2 will be powered off, and then the plug-in block 3 and the positioning frame 14 will be quickly separated, thereby achieving the effect of protecting the equipment and also protecting the connector. If the connector is subsequently checked and found to be not damaged, it can continue to be used, thereby extending the service life of the connector.

[0052] like Figure 6As shown, in this embodiment, an extrusion block 35 is fixedly connected to the upper surface of the rotating plate 33, and a limit frame 36 is fixedly connected to the upper surface of the plug block 3. A positioning groove 37 is provided in the limit frame 36. A second compression spring 38 is fixedly connected to the bottom wall of the positioning groove 37. A top block 39 is fixedly connected to the top of the second compression spring 38. The bottom wall of the positioning groove 37 is elastically connected to the internal foam cavity of the plug block 3, and the connecting pipe 13 is fixedly connected to the foam cavity.

[0053] Specifically, when the rotating plate 33 is released from the clamping, the rotating plate 33 will automatically flip and reset under the action of the torsion spring provided between the two positioning rods 32. During the flipping process, under the action of the torsion spring force, the extrusion block 35 fixed on the upper surface of the rotating plate 33 will squeeze the top block 39 on the upper surface of the plug block 3, and the top plate 319 will slide into the positioning groove 37 after being squeezed. At this time, the second compression spring 38 on the lower surface of the top plate 319 will also apply an extrusion force to the bottom wall of the positioning groove 37, thereby triggering the foam cavity inside the plug block 3, so that the foam cavity is punctured, and then the foam inside The foam fire extinguishing agent will be sprayed out from the nozzle at the end of the connecting pipe 13. The end of the connecting pipe 13 located inside the plug block 3 is provided with a nozzle. The connecting pipe 13 is made of copper and can conduct electricity. Therefore, the foam fire extinguishing agent sprayed out from the connecting pipe 13 is to prevent the temperature from changing too much when it is too high. At this time, the connector may have been burning. Cutting off the current in time can no longer control the burning. The small range of burning cannot be detected in time, which may lead to the expansion of the burning area. Therefore, by spraying the foam fire extinguishing agent at the same time, the working equipment is protected and the fire is prevented from expanding and causing greater losses.

[0054] Embodiment 2

[0055] like Figures 1 to 8 As shown, compared with Example 1, another embodiment of the present invention is: a fixed box 4 is fixedly connected to one side of the fixed plate 1, a third cavity 41 is opened in the fixed box 4, and two groups of silica gel blocks 42 are fixedly connected to the inner wall of the third cavity 41, and the silica gel blocks 42 are used for adsorbing corrosive gases and moisture in the air.

[0056] Specifically, a fixing box 4 is fixedly connected to one side of the fixing plate 1, and then two groups of silicone blocks 42 are fixedly connected to the inner wall of the third cavity 41 of the fixing box 4, so as to adsorb water mist close to the connector and reduce the adhesion of water molecules on the surface of the connector, thereby reducing the short circuit of the connector caused by water seepage and improving the working stability of the connector.

[0057] like Figure 8As shown, the fixed box 4 of this embodiment is internally rotatably connected with a plurality of fixed shafts 43, and a roller 410 is fixedly connected to the circumferential surface of each fixed shaft 43, and a first gear 44 is fixedly connected to one end of the fixed shaft 43, and the first gear 44 is transmission-connected to a first steel strip 46, and the end of the first steel strip 46 away from the first gear 44 is transmission-connected to a second gear 47, and a reciprocating screw 48 is fixedly connected to the middle of the second gear 47, and a push plate 49 is slidably connected to the circumferential surface of the reciprocating screw 48, and a water outlet 418 is opened on one side of the fixed box 4, and an inclined plate 416 is fixedly connected to the bottom wall of the fixed box 4, and the inclined plate 416 is used to guide the water flow.

[0058] Specifically, after the silicone block 42 in the fixed box 4 has been used for a certain period of time, by rotating a plurality of rollers 410 rotatably arranged in the fixed box 4, each roller 410 will drive the first gear 44 at one end thereof to rotate, and the rotation of the first gear 44 will drive the first steel strip 46 to transmit, and the transmission of the first steel strip 46 can drive the second gear 47 to rotate, and the rotation of the second gear 47 can drive the reciprocating screw 48 to rotate, and then the push plate 4 connected to the circumferential surface of the reciprocating screw 48 by sliding is driven. 9 will move toward the silica gel block 42. In the initial state, the push block 314 is in contact with the silica gel block 42. Therefore, when the reciprocating screw 48 drives the push block 314 to move, it can directly squeeze toward the silica gel block 42 to squeeze out the moisture in the silica gel block 42. Then, the water will flow to the inclined plate 416 on the bottom surface of the fixed box 4, and will flow out from the water outlet 418 of the fixed box 4 after being drained by the inclined plate 416, thereby ensuring the adsorption effect of the silica gel block 42 and improving the adsorption efficiency of the silica gel block 42.

[0059] like Figure 8 As shown, in this embodiment, a coil spring 45 is fixedly connected to one end of the roller 410 away from the first gear 44 . The coil spring 45 is fixedly connected to the inner wall of the fixed box 4 . An air inlet 417 is opened on the upper surface of the fixed box 4 .

[0060] Specifically, after the roller 410 rotates, the coil spring 45 arranged at one end of the roller 410 away from the first gear 44 will automatically rewind, and then drive the roller 410 to automatically rotate, and then it can drive the reciprocating screw 48 to rotate, so that the push plate 49 returns to its initial position, and an air inlet 417 is opened on the upper surface of the fixed box 4, which increases the contact area between the fixed box 4 and the air around the connector, thereby improving the effect of the fixed box 4 in protecting the connector.

[0061] like Figure 8As shown, in this embodiment, two slide grooves 412 are opened on one side of the fixed box 4, and slide rods 413 are slidably connected in the two slide grooves 412. The top ends of the two slide rods 413 are fixedly connected to the same cross plate 415, and the bottom ends of the two slide rods 413 are fixedly connected to the same slide plate 414, which is a rubber plate. A plurality of convex balls 411 are fixedly connected to the circumferential surface of each roller 410, and the convex balls 411 are rubber balls.

[0062] Specifically, when rotating the roller 410, because the connector is small, it is not very convenient to rotate it manually. Therefore, slide grooves 412 are opened on both sides of the fixed box 4, and then a slide rod 413 is slidably connected in each slide groove 412. The slide rod 413 is driven to move upward by pulling the cross plate 415, thereby controlling the same slide plate 414 fixed at the bottom ends of the two slide rods 413, so that the slide plate 414 is in contact with the roller 410. Because the roller 410 and the slide plate 414 are both made of rubber with a large friction coefficient, the roller 410 can be better driven to rotate by the slide plate 414, and a number of convex balls 411 are fixed on the circumferential surface of the roller 410 to improve the rotation efficiency of the roller 410, thereby achieving a more convenient processing of the silicone block 42, so that the water filled in the silicone block 42 can be squeezed out in time, so as to better use the silicone block 42.

[0063] Working principle: first, when the plug block 3 and the positioning frame 14 are plugged and powered on, the connecting tube 13 of the plug block 3 and the connecting pin 11 in the positioning frame 14 are plugged, and the plugging length is less than the width of the protrusion 25. When the connecting pin 11 inside the connector is short-circuited, the current at the connecting pin 11 will increase sharply, causing the temperature of the connecting pin 11 to rise rapidly. After the temperature of the connecting pin 11 rises, the temperature sensor 17 will monitor the temperature change. When the temperature exceeds the set temperature threshold, the temperature sensor 17 will detect the temperature change. After the temperature sensor 17 detects that the temperature is abnormal, the electrophoretic magnetic block 312 in the second cavity 311 is powered off. The electrophoretic magnetic block 312 loses its magnetism after the power is turned off. At this time, the third compression spring 313 releases its elastic force and then pushes the push block 314 to move toward the card block 34. During the movement of the push block 314 toward the card block 34, the elastically arranged limit block 317 in the card slot 315 on one side thereof abuts against the card block 34, and then the limit block 317 retracts into the card slot 315. During the process of retracting the card slot 315, the trapezoidal limit block 317 will squeeze the top plate 319 in the top groove 318, and then the top plate 319 will extend out of the top groove 318, and will push up the end of the rotating plate 33, so that the rotating plate 33 will be separated from the card block 34, and the contact plug block 3 and the positioning frame 14 will be stably plugged in. After the release, the temperature sensor 17 will control the electrophoresis magnetic column 22 in the fixed box 2 to cut off the power. After the electrophoresis magnetic column 22 is powered off, it will lose its magnetic force and will not be able to generate suction to the protrusion 25 which is also magnetic. With the suction force of the electrophoretic magnetic column 22, the first compression spring 24 will be released, pushing the protrusion 25 to squeeze the inclined block 31. Because the electrophoretic magnetic column 22 will absorb the protrusion 25 to squeeze the first root when it is energized, the inclined block 31 will be squeezed, so that the plug block 3 drives several connecting rods to separate from the connecting pin 11, so that the current passing through the connector is automatically cut off, so that the connector can be protected in time to prevent the connector from being melted or causing greater losses under the condition of continuous high current;

[0064] During the plug-in process of the plug-in block 3 and the positioning frame 14, a plurality of auxiliary rods 15 are fixedly connected to the inner wall of the positioning frame 14, and then when the plug-in block 3 is plugged in, a plurality of auxiliary frames 16 fixedly connected to one side thereof will be aligned with the auxiliary rods 15, and then the auxiliary frames 16 and the auxiliary rods 15 are plugged in together, thereby improving the plug-in stability of the positioning frame 14 and the plug-in block 3, and better connecting the connector and the device together;

[0065] In addition, when the rotating plate 33 is released from the clamping, the rotating plate 33 will automatically flip and reset under the action of the torsion spring set between the two positioning rods 32. During the flipping process, under the action of the torsion spring force, the extrusion block 35 fixed on the upper surface of the rotating plate 33 will squeeze the top block 39 on the upper surface of the plug block 3, and the top plate 319 will slide into the positioning groove 37 after being squeezed. At this time, the second compression spring 38 on the lower surface of the top plate 319 will also apply an extrusion force to the bottom wall of the positioning groove 37, thereby triggering the foam cavity inside the plug block 3, so that the foam cavity is punctured, and then the foam inside The fire extinguishing agent will be sprayed out from the nozzle at the end of the connecting pipe 13. The end of the connecting pipe 13 located inside the plug block 3 is provided with a nozzle. The connecting pipe 13 is made of copper and can conduct electricity. Therefore, the foam fire extinguishing agent sprayed out from the connecting pipe 13 is to prevent the connector from burning when the temperature is too high and the change is too large. At this time, the current cannot be cut off in time to control the burning. The small range of burning cannot be detected in time, which may lead to the expansion of the burning area. Therefore, by spraying the foam fire extinguishing agent at the same time, the working equipment is protected and the fire is prevented from expanding and causing greater losses.

[0066] When the connector is used, the fixing box 4 is fixed to one side of the fixing plate 1, and then two groups of silica gel blocks 42 are fixed to the inner wall of the third cavity 41 of the fixing box 4 to absorb the water mist close to the connector, thereby reducing the adhesion of water molecules on the surface of the connector, thereby reducing the short circuit of the connector caused by water seepage and improving the working stability of the connector;

[0067] After the silicone block 42 in the fixed box 4 has been used for a certain period of time, by rotating a plurality of rollers 410 rotatably arranged in the fixed box 4, each roller 410 will drive the first gear 44 at one end thereof to rotate after rotation, and the rotation of the first gear 44 will drive the first strip steel 46 to transmit, and the transmission of the first strip steel 46 can drive the second gear 47 to rotate, and the rotation of the second gear 47 can drive the reciprocating screw 48 to rotate, and then the push plate 49 slidably connected to the circumferential surface of the reciprocating screw 48 will move toward the silicone block 42, and the initial state is that the push block 314 is in contact with the silicone block 42, so when the reciprocating screw 48 drives the push block 314 to move, it can directly squeeze toward the silicone block 42, squeeze out the moisture in the silicone block 42, and then the water will flow to the inclined plate 416 on the bottom surface of the fixed box 4, and flow out from the water outlet 418 of the fixed box 4 through the drainage of the inclined plate 416, thereby ensuring the adsorption effect of the silicone block 42 and improving the adsorption efficiency of the silicone block 42.
