[0023] Example:

[0024] Reference Figure 1-Figure 4A waterproof and sealed circular electrical connector includes a connector seat 1, and an electrical connection portion is provided in the connector seat 1. The electrical connection portion includes an electrical connection end 102 fixedly provided in a plug-in slot 101, and multiple groups of pins 103 are fixedly provided on the electrical connection end 102. The pins 103 are provided in two to ten groups, preferably nine groups. The inner wall of the thermal conductive ring 4 is abutted against the outer wall of the electrical connection end 102. When in use, the heat on the electrical connection end 102 can be transferred to the thermal conductive ring 4, and then the heat can be dissipated to the outside of the connector seat 1 through the heat dissipation plate 501, thereby improving the heat dissipation effect and ensuring the reliable use of the connector seat 1. It also includes: a sealing ring 104, a plug-in slot 101 is opened on one end of the connector seat 1, the power connection part is set in the plug-in slot 101, and the connector is inserted into the plug-in slot 101 to achieve electrical connection. At this time, the seat of the connector will be against the sealing ring 104, which improves the waterproof and sealing effects. The sealing ring 104 is fixedly set on the open end face of the plug-in slot 101, and a first capsule 3 is fixedly set on the inner wall of the plug-in slot 101. An inflation component for inflating the first capsule 3 is provided on the connector seat 1. When in use, by fixing the sealing ring 104 on the connector seat 1, water can be reduced from entering the connector seat 1 during connection. The first capsule 3 is fixedly set on the inner wall of the plug-in slot 101, and after inflating the first capsule 3 , so that the first capsule 3 expands and wraps around the connector, further improving the waterproof and sealing effects; a heat-conducting ring 4 is fixedly arranged in the connector seat 1, and the inner wall of the heat-conducting ring 4 is pressed against the power connection part. The material of the heat-conducting ring 4 is ceramic or silicon nitride, preferably ceramic. Ceramic can achieve good thermal conductivity while maintaining good insulation, and multiple groups of heat dissipation plates 501 are arranged on the heat-conducting ring 4, and the heat dissipation plates 501 are arranged in two to twenty groups, preferably four groups. When in use, by pressing the inner wall of the heat-conducting ring 4 against the outer wall of the power connection end 102, the heat in the power connection end 102 and the connector seat 1 can be transferred to the heat dissipation plate 501 through the heat-conducting ring 4, and dissipated to the outside through the heat dissipation plate 501, thereby improving the heat dissipation effect and ensuring the reliable operation of the connector seat 1.

[0025] Reference Figure 1-Figure 4 A threaded barrel 2 is sleeved on the connector seat 1, a rotating groove 106 is opened on the outer wall of the connector seat 1, and a rotating ring 201 is sleeved in the rotating groove 106, and the outer wall of the rotating ring 201 is fixedly connected to the inner wall of the threaded barrel 2. When in use, by sleeved on the connector seat 1 with the threaded barrel 2, the reliable connection between the connector seat 1 and the connector can be ensured, and looseness can be reduced. Moreover, the rotating ring 201 is sleeved on the connector seat 1 to prevent the threaded barrel 2 from falling off the connector seat 1 and affecting normal use.

[0026] Reference Figure 1-Figure 4A guide block 105 is fixedly provided on the inner wall of the plug-in slot 101, and the guiding direction of the guide block 105 is parallel to the axis of the plug-in slot 101. That is to say, when the connector is plugged into the plug-in slot 101, the guide block 105 can guide the connector to ensure correct connection, and when the threaded barrel 2 is rotated, it can prevent the connector and the connector seat 1 from rotating with the threaded barrel 2, resulting in abnormal use.

[0027] Reference Figure 3 and Figure 4 The inflation component can use an air pump or a fan to inflate the first sac 3. Here, we design the inflation component as: a second sac 301, and fix the second sac 301 on the inner wall of one end of the rotating groove 106. The first sac 3 and the second sac 301 are both annular structures. The first sac 3 is connected to the second sac 301 through a channel, and the side wall of the rotating ring 201 is abutted against the second sac 301. After the connector is completed, the rotating threaded barrel 2 is threadedly connected to the seat of the connector. During this process, the rotating ring 201 can squeeze the second sac 301, the gas in the second capsule 301 is pressed into the first capsule 3 through the channel, so that the first capsule 3 expands and wraps around the outer wall of the connector, which can improve the waterproof and sealing effect between the connector and the plug-in slot 101. Moreover, after the threaded barrel 2 is connected, the rotating ring 201 and the second capsule 301 are abutted against each other, which can improve the sealing effect between the threaded barrel 2 and the connector seat 1. When the connector is pulled out, the first capsule 3 and the second capsule 301 are elastically restored, that is, the gas in the first capsule 3 returns to the second capsule 301, thereby improving the use effect.

[0028] Reference Figure 4 , multiple groups of limiting grooves 401 are evenly provided on the heat-conducting ring 4, and the limiting grooves 401 are provided with two to ten groups, preferably four groups. The heat-conducting plates 5 are respectively slidably provided in the four groups of limiting grooves 401, and the four groups of heat-dissipating plates 501 are respectively fixedly connected to the corresponding heat-conducting plates 5, and the top of the heat-dissipating plate 501 is abutted against the inner wall of the rotating ring 201, and a spring is provided in the limiting groove 401, and the two ends of the spring are respectively abutted against the limiting groove 401 and the heat-conducting plate 5. When the connector seat 1 is not in use, the top of the heat-dissipating plate 501 is abutted against the inner wall of the rotating ring 201. At this time, the heat sink 501 is located in the limiting groove 401, which can reduce dust falling on the heat sink 501, and under the elastic force of the spring, the top of the heat sink 501 is against the inner wall of the rotating ring 201, which can provide a certain resistance for the sliding of the rotating ring 201 and reduce the possibility of its sliding. When the connector seat 1 is in use, the threaded barrel 2 is threadedly connected to the seat body of the connector, and the rotating ring 201 slides over the heat sink 501. Under the elastic force of the spring, the heat sink 501 can rise from the limiting groove 401, and at this time, the heat dissipation effect can be improved.

[0029] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
