[0002] A connector is an electronic component used to connect two active devices to achieve current or signal transmission. It is a basic component necessary for the connection of the entire system and is widely used in various electronic devices and systems. In electronic devices, many electrical connections require efficient heat dissipation to ensure stable operation and extend the service life of the equipment. For example, components such as transformers and rectifiers in power supplies generate heat when working, and a heat dissipation system is required to maintain their stable operation.

[0003] Patent with authorization announcement number CN221727494U discloses an electrical connector including an insulating body with a slot and a power terminal fixed to the insulating body. The power terminal includes an elastic arm with a contact portion protruding into the slot and a mounting pin extending out of the insulating body.

DETAILED DESCRIPTION

[0029] 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.

[0030] like Figure 1-Figure 8 As shown, an air-cooled circuit connector of the present invention comprises a connecting tube body 1, one end of the connecting tube body 1 is provided with a first expansion cover 12, a first air-cooling channel 121 is provided through the side wall of the connecting tube body 1, a plug-in outer cover 13 is rotatably provided at the end of the connecting tube body 1 away from the first expansion cover 12, a plug-in inner ring 14 is provided on the inner wall of the plug-in outer cover 13, the plug-in outer cover 13 and the plug-in inner ring 14 form a cavity, and the first air-cooling channel 121 penetrates the connecting tube body 1 at the end away from the first expansion cover 12 and is in communication with the cavity formed by the plug-in outer cover 13 and the plug-in inner ring 14;

[0031] The opening of the first air cooling channel 121 is rounded, and the diameter of the first air cooling channel 121 is between 90 mm and 110 mm. The thickness of the first expansion cover 12 is between 50 mm and 70 mm, and the first expansion cover 12 is made of polybutylene terephthalate.

[0032] When the connector is used, one end of the connector is connected to the main line 3, and the other end is plugged into another component. The two components are connected through the connector, and the connection of the component is inserted into the connection socket 16. When it is windy outdoors, more air can flow into the first air cooling channel 121 through the first air cooling channel 121, wherein the first air cooling channel 121 runs through the connecting tube body 1, and the connecting tube body 1 can be air-cooled when the wind passes through, so as to facilitate the heat dissipation of the electrical components placed in the connecting tube body 1. The diameter of the first air cooling channel 121 is set at 90 The thickness of the first expansion cover 12 is between 50mm and 70mm, which can increase the air flow rate when the air passes through the first expansion cover 1 and enters the first air cooling channel 121, so as to achieve a better heat dissipation effect. The first expansion cover 12 is made of polybutylene terephthalate, which has high heat resistance and a thermal deformation temperature of about 200°C (the glass fiber reinforced type can be higher), so that it can maintain stable performance at a higher temperature. The surface is smooth, has self-lubricating properties, and has a low friction coefficient, which helps to reduce wear and friction noise. The thickness of the first expansion cover 12 is 50mm to 70mm, which has sufficient strength.

[0033] The airflow enters the cavity formed by the plug-in outer cover 13 and the plug-in inner ring 14 and flows through the bottom of the cavity formed by the plug-in outer cover 13 and the plug-in inner ring 14, so that the gas can dissipate heat to the connecting pipe body 1 while also dissipating heat secondary through the outer wall of the plug-in inner ring 14.

[0034] Specifically, the external fixing sleeve of the connecting pipe body 1 is provided with a first air-cooling ring 2, the edge of the first air-cooling ring 2 is corrugated, and the first air-cooling ring 2 is made of aluminum alloy, and the corrugated ends of the first air-cooling ring 2 are all provided with chamfers.

[0035] The first air-cooling ring 2 is made of aluminum alloy and is relatively light in weight. At the same time, it can also dissipate heat for the connecting pipe body 1 in a timely manner. The corrugated shape arranged at the edge of the first air-cooling ring 2 can increase the basic area with the air, thereby achieving a faster heat dissipation effect.

[0036] Specifically, a boss is provided at one end of the connecting tube body 1 away from the first expansion cover 12, and a second expansion cover 15 is provided on one side of the boss. The diameter of the second expansion cover 15 is larger than the diameter of the first expansion cover 12, and a second air duct 151 is provided through the side wall of the boss. The second air duct 151 is inclined, and one end of the second air duct 151 is connected to the cavity formed by the plug-in outer cover 13 and the plug-in inner ring 14.

[0037] The boss can block the air, which is beneficial for the air to enter the second expansion cover 15. At the same time, it can also support the connection of the plug-in outer cover 13. The second expansion cover 15 can collect the air and then enter the cavity formed by the plug-in outer cover 13 and the plug-in inner ring 14 through the second air duct 151. The middle part of the plug-in outer cover 13 is plugged with the connection end of the component, which can cool the internal connection end to ensure that the temperature inside the connector is not too high, which is beneficial to ensure the normal operation of the components.

[0038] Specifically, the boss is fixedly connected to a supporting cross bar near the plug-in outer cover 13, and a torsion spring 18 is sleeved on the outer wall of the supporting cross bar. The plug-in outer cover 13 consists of two groups, and one end of the plug-in outer cover 13 near the torsion spring 18 is rotatably connected to the side wall of the boss, and the two ends of the torsion spring 18 are respectively fixedly connected to the corresponding plug-in outer covers 13 on both sides, and a plurality of tension springs 17 are arranged in the middle of one end of the two plug-in outer covers 13 near the torsion spring 18.

[0039] The torsion spring 18 disposed outside the supporting cross bar can give the two plug-in covers 13 a force to rotate. When the internal temperature of the plug-in covers 13 exceeds a preset range, the two plug-in covers 13 will rotate open, so that the bottom of the plug-in covers 13 can be exposed to the air, which can dissipate heat to the greatest extent. When the plug-in covers 13 are opened, the staff can promptly discover problems with the connector, which is convenient for the staff to promptly discover damaged areas and perform repairs in a timely manner.

[0040] The coordinated arrangement of the tension spring 17 and the torsion spring 18 can separate the two plug-in covers 13 more quickly, wherein before the two plug-in covers 13 are opened, the tension spring 17 is in a compressed state, and when the plug-in covers 13 are rotated to open, the two ends of the tension spring 17 pull the sides of the tops of the two plug-in covers 13 that are close to each other to rotate, thereby accelerating the separation of the bottoms of the two plug-in covers 13. The opening of the bottoms of the two plug-in covers 13 accelerates heat dissipation, and at the same time, the tops of the plug-in covers 13 can block rainwater, thereby preventing rainwater from entering in rainy weather.

[0041] Specifically, the outer wall of the plug-in outer cover 13 is provided with a second air-cooling ring 21 , which is semicircular, and the edge of the second air-cooling ring 21 is provided with the same corrugated shape as the first air-cooling ring 2 .

[0042] The second air-cooling ring 21 can continuously dissipate heat for the plug-in outer cover 13. The second air-cooling ring 21 is made of aluminum alloy and has a good heat dissipation effect. The second air-cooling ring 21 is attached to the outer wall of the plug-in outer cover 13. The second air-cooling ring 21 uses the thermal conductivity of the aluminum alloy to accelerate the heat dissipation of the plug-in outer cover 13 to ensure that the internal temperature is not too high. When taking it, the corrugated setting at the edge can play an anti-slip role.

[0043] Specifically, the plug-in outer cover 13 is fixedly connected to the plug-in inner ring 14 by a connecting rod. The middle of the plug-in outer cover 13 is hollow to form an inner cavity 131. A guide groove 133 is formed on the inner wall of one end of the plug-in outer cover 13 away from the supporting cross bar, and a sliding column 67 is movably arranged in the guide groove 133.

[0044] The sliding column 67 can slide along the inner wall of the guide groove 133. The sliding column 67 can also rotate during the sliding process. During the rotation of the plug-in outer cover 13, the plug-in inner ring 14 can be driven to rotate synchronously. The plug-in inner ring 14 can support and tighten the connecting end of the component. The rotation of the plug-in inner ring 14 can expose the connecting end of the component to the outside for faster heat dissipation. A step is provided at the opening of the plug-in inner ring 14, which can facilitate smoother insertion of the connecting end of the component.

[0045] Specifically, a stretching block 66 is fixedly sleeved on the outer wall of the sliding column 67, and a through hole block 661 is fixedly connected to one side of the stretching block 66, and a round hole is provided in the middle of the through hole block 661;

[0046] The inner wall of the inner cavity 131 of the plug-in outer cover 13 is fixedly attached with a high-pressure airbag 6, and one end of the high-pressure airbag 6 close to the stretching block 66 is fixedly penetrated with a gas pressure rod 61, and the gas pressure rod 61 is fixedly connected to the inner wall of the plug-in outer cover 13, and the telescopic end of the gas pressure rod 61 is provided with a telescopic hook 611, and the telescopic hook 611 is provided in cooperation with the circular hole provided in the middle of the through hole block 661;

[0047] A limit plate 62 is fixedly connected to the middle of the upper surface of the guide groove 133, and the limit plate 62 is connected to the stretching block 66 by a pull spring 65. The end of the guide groove 133 away from the stretching block 66 is rotatably connected to a rotating shaft 63, and the rotating shaft 63 is connected to a sliding column 67 in the opposite side plug-in outer cover 13 through a connecting rod 64.

[0048] In the initial state, the telescopic hook 611 is hooked in the circular hole provided in the middle of the through-hole block 661. When the internal temperature of the connector rises, the gas pressure inside the high-pressure airbag 6 will increase. When the air pressure increases to a preset value, the telescopic end of the gas pressure rod 61 will extend and push the telescopic hook 611 to move. When the telescopic hook 611 moves to separate from the through-hole block 661, the bottoms of the two plug-in covers 13 will rotate in the direction away from each other. At the same time, the stretching block 66 will follow the sliding column 67 to slide along the inner wall of the inner cavity 131, and the ends of the two connecting rods 64 will follow the sliding column 67 to move. When the sliding column 67 moves to the preset position, the limit plate 62 will block the sliding column 67. The plug-in cover 13 can be opened but not fully opened to still cover the connecting end of the component inside to prevent rainwater from entering in rainy weather, and still protect it. The opening of the plug-in cover 13 can increase the heat dissipation of the component and avoid burning due to overheating of the connecting end of the component.
