Description

Technical Field

[0002] In today's highly information-based and intelligent age, integrated circuits, as core components of electronic devices, are widely used in various fields such as communications, computers, consumer electronics, and industrial control. As one of the key devices in the application of integrated circuits, the integrated circuit commutation device mainly changes the transmission direction of the integrated circuit to meet the needs of different circuit layouts and signal processing.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Among them, when the integrated circuit commutation device is in use, a protective shell 2 is installed on the outer surface of the commutation device body 1 to protect the commutation device body 1, and baffles 411 are installed on both sides for shielding. At the same time, a shielding plate 3 is installed in conjunction with the installation to shield the magnetic field outside the commutation device body 1, thereby avoiding interference with the inside of the commutation device body 1 and affecting the stable output and commutation use of the integrated circuit. Since a through hole for replacing parts is provided between the baffle 411 and the shielding plate 3, the through hole will affect the sealing of the commutation device body 1. The gap between the baffle 411 and the shielding plate 3 can be sealed by the conductive rubber ring 413; and an inner semicircular groove 425 is provided on the outer surface of the conductive rubber ring 413. By filling the inner semicircular groove 425 with lubricating oil, the sealing effect between the conductive rubber ring 413 and the shielding plate 3 and the baffle 411 is ensured by the lubricating oil, thereby increasing the stability of the commutation device operation. Furthermore, the lubricating oil can be introduced into the annular groove formed by the inner semicircular groove 425 and the outer semicircular groove 412 through the air pump 421, thereby achieving stable filling of the inside of the annular groove, and the air collecting cylinder 431 is connected at the other end of the annular groove, and the interior of the air collecting cylinder 431 is exhausted through the suction end of the air pump 421, thereby avoiding unstable air pressure inside the reversing groove and ensuring the filling stability of the lubricating oil inside the annular groove. The inside of the annular groove can be continuously exhausted by the action of the breathable film 435 installed inside the annular groove to eliminate the bubbles remaining in the annular groove, so that the tightness of the lubricating oil inside the annular groove is better.

[0024] In some embodiments, baffles 411 are fixedly installed at both ends of the commutation device body 1, and a shielding plate 3 for shielding the external magnetic field is installed on the outer surface of the baffle 411, and a conductive rubber ring 413 is arranged between the baffle 411 and the shielding plate 3.

[0025] Among them, a conductive rubber ring 413 is provided between the baffle 411 and the shielding plate 3, so as to achieve the closure of the through hole and reduce the impact of gas leakage inside the protective shell 2; during the assembly process of the integrated circuit commutation device, there will inevitably be tiny gaps between the components. The conductive rubber ring 413 has good elasticity and flexibility, and can undergo elastic deformation, tightly filling these gaps, effectively preventing external dust, moisture, impurities, etc. from entering the interior of the device, protecting the integrated circuit from pollution and damage, and ensuring the cleanliness of the internal environment of the device. At the same time, the conductive rubber ring 413 has conductive properties, which can timely discharge the static electricity generated inside the device and the surrounding environment, avoid static electricity accumulation, thereby preventing electrostatic discharge from damaging the integrated circuit, and improving the reliability and stability of the device; the shielding plate 3 can shield the external magnetic field, reduce the interference of the external magnetic field on the integrated circuit inside the commutation device body 1, and ensure the stable output and commutation use of the integrated circuit.

[0026] In some embodiments, the exhaust assembly 43 further includes a breathable film 435 connected to and mounted on the exhaust pipe 432 . Two support plates 434 are mounted on the exhaust pipe 432 , and the breathable film 435 is located between the two support plates 434 .

[0027] Among them, the breathable film 435 allows gas to pass through and prevents liquids such as lubricating oil from passing through. When the air pump 421 exhausts the gas collecting cylinder 431 through the exhaust pipe 432, the breathable film 435 can continuously exhaust the inside of the annular groove, eliminate the bubbles remaining in the annular groove, and make the lubricating oil tightly fill the annular groove, further improving the sealing effect and ensuring the sealing performance between the conductive rubber ring 413 and the shielding plate 3 and the baffle 411.

[0028] In some embodiments, a rolling block 433 for pressurizing the exhaust pipe 432 is rotatably installed on the baffle 411 and the shielding plate 3 near the outer surface of the exhaust pipe 432 , and the cross section of the rolling block 433 is cam-shaped.

[0029] Among them, by rotating the rolling block 433, its cam structure can pressurize the exhaust pipe 432, change the pressure in the exhaust pipe 432, thereby affecting the air pressure in the annular groove, assisting the filling of lubricating oil and the removal of bubbles, and improving the sealing effect and the stability of the device operation.

[0030] In some embodiments, a lubrication assembly 42 is provided on the outer surface of the reversing device body 1. The lubrication assembly 42 includes a lubrication cylinder 423 installed on the outer surface of the reversing device body 1. A piston is provided inside the lubrication cylinder 423. The output end of the air pump 421 is connected to one end of the lubrication cylinder 423 through an air inlet pipe 422. The free end of the lubrication cylinder 423 is connected to an oil outlet pipe 424, and the oil outlet pipe 424 is connected to the annular groove.

[0031] Among them, when the air pump 421 is running, the gas enters the lubricating cylinder 423 through the air inlet pipe 422, pushes the piston to move, and presses the lubricating oil in the lubricating cylinder 423 into the annular groove through the oil outlet pipe 424, thereby realizing a stable supply of lubricating oil, ensuring good lubrication between the conductive rubber ring 413 and the shielding plate 3 and the baffle 411, reducing friction and wear, extending the service life of the device, and ensuring the sealing effect.

[0032] In some embodiments, a sealing ring 414 is provided in the annular groove formed by the inner semicircular groove 425 and the outer semicircular groove 412, a reinforcement ring 426 is installed inside the sealing ring 414 for stabilizing the sealing ring 414, and a plurality of protrusions 429 for guiding the lubricating oil are installed on the outer surface of the sealing ring 414.

[0033] Among them, the reinforcement ring 426 can stabilize the sealing ring 414 and keep it stable in the annular groove; the protrusion 429 can guide the lubricating oil, promote the flow of lubricating oil in the annular groove, make the lubricating oil evenly distributed, and improve the sealing effect and reliability of the device operation.

[0034] In some embodiments, a partition 427 is rotatably installed on the outer surface of the conductive rubber ring 413, a sliding groove is provided near the partition 427 of the conductive rubber ring 413, a slider is slidably installed inside the sliding groove, the partition 427 is fixedly connected to the sealing ring 414 through the slider, and a rotating rod 428 is installed on the outer surface of the partition 427.

[0035] Among them, the rotating rod 428 drives the partition 427 to rotate, and the partition 427 drives the sealing ring 414 to rotate. The protrusion 429 on the outer surface of the sealing ring 414 promotes the flow of lubricating oil in the annular groove, so that the lubricating oil slowly fills the annular groove, accelerates the removal of bubbles, and improves the filling effect and sealing performance of the lubricating oil.

[0036] In some embodiments, a limiting mechanism 44 is provided inside the protective shell 2, and the limiting mechanism 44 includes a negative pressure cylinder 444 installed inside the protective shell 2, and a gas rod 442 is slidably installed inside the negative pressure cylinder 444, and the free end of the gas rod 442 is fixedly installed with a pressure plate 441 for clamping the shielding plate 3, and the pressure plate 441 is installed with screws, and a spring 443 is fixedly installed between the negative pressure cylinder 444 and the pressure plate 441, and the top end of the negative pressure cylinder 444 is connected to the installation of an intake pipe 445 for negative pressure exhaust, and the input end of the air pump 421 and the protective shell 2 are connected to the installation of a connecting pipe 45 for vacuuming the inside of the protective shell 2.

[0037] Among them, when the air pump 421 is running, the inside of the protective shell 2 is vacuumed through the connecting pipe 45, so as to ensure the vacuum protection effect of the internal parts of the reversing device body 1. At the same time, when vacuuming, the negative pressure cylinder 444 is exhausted through the suction pipe 445, and the action of the spring 443 is combined with the pressure plate 441 to pressurize and limit the shielding plate 3 and the baffle 411, so that the conductive rubber ring 413 can be used more tightly, reducing the loosening of the seal due to vibration and other reasons, and improving the sealing performance and operation stability of the device.

[0038] In some embodiments, the inner surface of the reversing device body 1 is covered with an anti-friction plate 5 , and a plurality of support pads 6 are installed between the anti-friction plate 5 and the protective shell 2 .

[0039] Among them, the anti-friction plate 5 can reduce the friction between the inner surface of the reversing device body 1 and other components, and the support pad 6 can support and buffer the protective shell 2 to ensure the relative position between the protective shell 2 and the reversing device body 1 is stable.

[0040] Working principle: When the integrated circuit commutation device is in use, a baffle 411 and a shielding plate 3 are installed on the outer surface of the commutation device body 1 to shield the magnetic field outside the commutation device body 1, thereby avoiding interference with the inside of the commutation device body 1 and affecting the stable output and commutation use of the integrated circuit. At the same time, the conductive rubber ring 413 can seal the gap between the baffle 411 and the shielding plate 3, and the annular groove opened on the outer surface of the conductive rubber ring 413 is filled with lubricating oil. The lubricating oil ensures the sealing effect between the conductive rubber ring 413 and the shielding plate 3 and the baffle 411, thereby increasing the stability of the commutation device operation. At the same time, the lubricating oil can be introduced into the annular groove formed by the inner semicircular groove 425 and the outer semicircular groove 412 through the air pump 421, thereby achieving stable filling and sealing inside the annular groove, and the other end of the annular groove is connected to the air collecting cylinder 431. The air pump 421 cooperates with the breathable film 435 to continuously exhaust the inside of the annular groove to remove the bubbles remaining in the annular groove, so that the tightness of the lubricating oil inside the annular groove is better.
