Description

Technical Field

[0001] The present invention relates to the field of isolators, in particular to a circuit isolator separation safety device. Background Art

[0002] The signal isolator first modulates and transforms the signal of the transmitter or instrument through semiconductor devices, then isolates and converts it through optical or magnetic induction devices, and then demodulates and transforms it back to the original signal before isolation. At the same time, the power supply of the isolated signal is isolated to ensure that the converted signal, power supply, and ground are absolutely independent.

[0003] According to Chinese patent publication number CN213522919U, a new multifunctional signal isolator is disclosed. This invention adds a heat dissipation structure, which allows it to dissipate heat within the isolator at any time, thereby enhancing the isolator's isolation effect. The device is easy to install and operate, and has high safety and stability, making it worthy of promotion. At the same time, because the isolator is fixed by inserting a card block into a card slot and using the action of a spring, when the isolator is bumped and moved, it still pushes the card block to move, causing the card block to move out of the card slot, thereby making the isolator unstable and easy to move, and reducing the isolator's fixing efficiency. At the same time, because the surface of the heat sink has heat dissipation holes, the heat generated by the isolator during operation can be dissipated through the heat dissipation holes. However, when heat dissipation is not required, external dust will continue to enter the heat sink through the heat dissipation holes and adhere to the side of the heat dissipation net close to the mounting plate. Over time, it is easy for a large amount of dust to adhere to the heat dissipation net and may cause clogging of the heat dissipation net, thereby affecting the subsequent air circulation efficiency and reducing the heat dissipation efficiency of the isolator. Summary of the Invention

[0004] Based on this, the purpose of the present invention is to provide a loop isolator disengagement safety device to solve the technical problems of unstable fixation of the isolator and the easy adhesion of a large amount of dust on the side of the heat dissipation net close to the mounting plate, thereby affecting the heat dissipation efficiency.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a loop isolator disengagement safety device, comprising a mounting plate, a card slot being provided on one side of the mounting plate, a card block being connected inside the card slot, a heat sink being installed on one side of the card block, a plug-in slot being provided on one side of the heat sink, an isolator being plugged into the plug-in slot, cavities being provided above and below the interior of the heat sink, a card connection assembly being provided inside the cavity, a heat dissipation hole being provided on one side of the outer surface of the heat sink, a dustproof net being installed inside the heat dissipation hole, and a sealing assembly being provided on the outer surface of the heat sink.

[0006] By adopting the above technical solution, after the card block is inserted into the card slot, the user can quickly install the heat sink. At the same time, after the isolator is inserted into the socket, it is convenient to limit and fix it. The heat generated by the isolator can be dissipated through the heat dissipation holes. At the same time, the setting of the dust net can reduce the amount of dust entering the socket slot.

[0007] Furthermore, the clamping assembly includes bearings installed above one side and below one side of the heat sink, multiple first springs fixed to one side of the cavity, a baffle fixed above the cavity and multiple second springs, a sliding rod fixed to the cavity and a clamping hole opened at the top and bottom of the isolator, the bottom ends of the multiple second springs are fixed with a movable rod, the top of one movable rod and the bottom of another movable rod are fixed with multiple clamping rods, the bottom of one movable rod and the top of another movable rod are installed with a top block, one end of the first spring is fixed with a push block, one side of the push block is fixed with a pressure rod extending to the outside of the heat sink, one end of the pressure rod is fixed with a pressure block, the outer surface of the pressure block is provided with a limiting groove, the outer surface of the sliding rod is sleeved with a sliding sleeve, and one end of the bearing is installed with a limiting plate through the damping shaft.

[0008] By adopting the above technical solution, when the isolator is inserted into the plug-in slot and needs to be limited and fixed, the user can press the pressure block, which will drive the pressure rod to move and stretch the first spring, and at the same time drive the push block to move. After the push block contacts the top block, as the push block continues to move, it will push the top block to move, so that the movable rod drives the card rod to move, and then the card rod can be locked into the card hole to limit the isolator.

[0009] Furthermore, one side of the sliding sleeve is connected to one end of the movable rod, the movable rod is slidably connected to the sliding rod through the sliding sleeve, and the push block is located on one side of the top block.

[0010] By adopting the above technical solution, when the movable rod moves, it will drive the sliding sleeve to move, and the movable rod will stretch or squeeze the second spring, and at the same time, the push block will squeeze the top block when it moves.

[0011] Furthermore, the number of the clamping rods corresponds to the number of the clamping holes, the clamping rods are matched with the clamping holes, and the limiting plates are matched with the limiting grooves.

[0012] By adopting the above technical solution, the clamping rod can be clamped into the clamping hole, and then the isolator can be limited and fixed to prevent the isolator from moving at will.

[0013] Furthermore, the sealing assembly includes a wire pulley installed on the top and bottom of the heat sink, a pull rope fixed on the top of the slide sleeve, and a slide groove opened on the outer surface of the heat sink. Return springs are fixed on the upper and lower parts of the slide groove. One end of the return spring is connected to a slider, and a sealing plate is installed on one side of the slider through a connecting rod.

[0014] By adopting the above technical solution, when the isolator is taken out, the movement of the sliding sleeve can loosen the pull rope. At this time, the reset spring recovers its elasticity and stretches to push the slider to reset. The reset of the slider can drive the sealing plate to reset, so that the two sealing plates are closed and block the heat dissipation holes. In the sealing process, the dust attached to the surface of the dustproof net can be cleaned off to prevent the dust from covering the surface of the dustproof net all the time, thereby improving the cleaning efficiency of the dustproof net surface.

[0015] Furthermore, the blocking plate is semicircular, and is slidably connected to the slide groove via a connecting rod and a slider, and the back of the blocking plate is in contact with the outer surface of the heat sink.

[0016] By adopting the above technical solution, the blocking plate can drive the slider to move when it moves up and down, and the slider can slide inside the sliding groove and squeeze or stretch the reset spring.

[0017] Furthermore, the diameter of the blocking plate is larger than the diameter of the heat dissipation hole, and one end of the pull rope passes through the wire pulley and is connected to the top of the blocking plate.

[0018] By adopting the above technical solution, the blocking plate can be pulled up when the pull rope is wound up, so that the blocking plate no longer blocks the heat dissipation hole. At this time, the heat inside the heat dissipation seat can be dissipated through the heat dissipation hole.

[0019] Furthermore, the clamping block is fixedly connected to the mounting plate by fastening bolts, a heat dissipation net is fixed inside the plug slot, and limiting blocks are fixed above and below the inside of the plug slot, and one side of the isolator is in contact with the limiting block.

[0020] By adopting the above technical solution, the user can fix the block by tightening the bolts to prevent the block from moving at will. At the same time, the setting of the limit block can prevent the isolator from moving further into the interior of the socket.

[0021] In summary, the present invention mainly has the following beneficial effects:

[0022] When the locking plate is in the same horizontal line as the locking groove, the locking plate is released, and the first spring recovers its elasticity and drives the locking plate to move slightly, so that the limiting plate can be locked in the limiting groove, and then the locking plate can be limited to prevent it from moving, thereby ensuring that the locking plate will not move out of the locking hole, so that the locking plate can always limit the isolator, thereby improving the fixing efficiency of the isolator and avoiding the situation that the isolator moves due to unstable fixation.

[0023] 2. The present invention is provided with a blocking component. When the isolator is taken out, the sliding sleeve moves to loosen the draw rope. At this time, the reset spring recovers its elasticity and stretches to push the slider to reset. The reset of the slider can drive the blocking plate to reset, so that the two blocking plates are closed and block the heat dissipation holes. In the blocking process, dust attached to the surface of the dustproof net can be cleaned to prevent dust from covering the surface of the dustproof net all the time, thereby improving the cleaning efficiency of the dustproof net surface. After the blocking plate blocks the heat dissipation holes, it can prevent external dust from entering the interior of the plug-in slot through the heat dissipation holes, so that there will not be much dust attached to the side of the heat dissipation net close to the mounting plate, preventing dust from covering the heat dissipation net, ensuring that the heat generated by the subsequent isolator operation can be discharged through the heat dissipation net and the heat dissipation holes.

The first spring 806 is moved and stretched, and the push block 809 is driven to move at the same time. After the push block 809 contacts the top block 816, as the push block 809 continues to move, it pushes the top block 816 to move, so that the movable rod 808 drives the card rod 812 to move, and then the card rod 812 can be stuck into the inside of the card hole 815 to limit the isolator 7. The outer surface of the slide rod 814 is sleeved with a sliding sleeve 813, and one side of the sliding sleeve 813 is connected to one end of the movable rod 808.

[0035] See Figure 1 、 Figure 2 、 Figure 3 and Figure 6The sealing assembly 9 includes a wire wheel 901 installed on the top and bottom of the heat sink 5, a pull rope 902 fixed to the top of the sliding sleeve 813 and a slide groove 906 opened on the outer surface of the heat sink 5. A return spring 904 is fixed on the upper and lower parts of the slide groove 906. One end of the return spring 904 is connected to a slider 905. When the isolator 7 is taken out, the sliding sleeve 813 moves to loosen the pull rope 902. At this time, the return spring 904 recovers its elasticity and stretches to push the slider 905 to reset. The reset of the slider 905 can drive the blocking plate 903 to reset, so that the two blocking plates 903 are closed and block the heat dissipation hole 11. In the blocking process, the dust attached to the surface of the dustproof net 12 can be cleaned to prevent the dust from covering the surface of the dustproof net 12 all the time, thereby improving the To improve the cleaning efficiency of the surface of the dustproof net 12, a blocking plate 903 is installed on one side of the slider 905 through a connecting rod 907. The diameter of the blocking plate 903 is larger than the diameter of the heat dissipation hole 11. One end of the pull rope 902 is connected to the top of the blocking plate 903 through the wire pulley 901. The blocking plate 903 is semicircular, and the blocking plate 903 is slidably connected to the slide groove 906 through the connecting rod 907 and the slider 905.

At the same time, when the pull rope 902 is wound, the blocking plate 903 can be pulled up so that the blocking plate 903 no longer blocks the heat dissipation hole 11. At this time, the heat inside the heat dissipation seat 5 can be dissipated through the heat dissipation hole 11.

[0036] The implementation principle of this embodiment is as follows: first, the user can insert the card block 3 into the card slot 2 and fix the card block 3 by tightening the bolt 4 to prevent the heat sink 5 from moving, and then install the mounting base 1 on the card board, and then insert the isolator 7 into the inside of the plug-in slot 13, and by pressing the pressure block 801, the pressure block 801 will drive the pressure rod 810 to move and stretch the first spring 806, and at the same time drive the push block 809 to move. After the push block 809 contacts the top block 816, as the push block 809 continues to move, it will push the top block 816 to move, so that The movable rod 808 drives the clamping rod 812 and the sliding sleeve 813 to move, and then the clamping rod 812 can be clamped into the clamping hole 815 to limit the isolator 7. Then, by rotating the limiting plate 803, the limiting plate 803 and the limiting groove 802 are in the same horizontal straight line. Then, the pressure block 801 is released, and the first spring 806 recovers its elasticity and drives the pressure block 801 to move slightly, so that the limiting plate 803 can be clamped into the limiting groove 802, and then the pressure block 801 can be limited to prevent it from moving, thereby ensuring that the clamping rod 812 will not move out of the clamping hole 815. When the isolator 7 is taken out, the card rod 812 is always limited to the isolator 7, and the sliding sleeve 813 moves to pull the pull rope 902. When the pull rope 902 is pulled, the blocking plate 903 is pulled to move, and the slider 905 slides in the slide groove 906 and squeezes the return spring 904, so that the return spring 904 is compressed. After the two blocking plates 903 are separated, they no longer block the heat dissipation hole 11. At this time, the heat generated by the isolator 7 will be dissipated through the heat dissipation hole 11. When the isolator 7 is taken out, the sliding sleeve 813 moves to loosen the pull rope 902. At this time, the return spring 904 The elasticity is restored and stretched, and then the slider 905 is pushed to reset. The reset of the slider 905 can drive the sealing plate 903 to reset, so that the two sealing plates 903 are closed and block the heat dissipation hole 11, and the dust attached to the surface of the dustproof net 12 can be cleaned during the blocking process. After the sealing plate 903 blocks the heat dissipation hole 11, it can prevent external dust from entering the interior of the plug-in slot 13 through the heat dissipation hole 11, so that there will not be much dust attached to the side of the heat dissipation net 10 close to the mounting plate 1, ensuring that the heat generated by the subsequent operation of the isolator 7 can be discharged through the heat dissipation net 10 and the heat dissipation hole 11.
