[0022] like Figures 1 to 7 As shown, the utility model relates to an electrical connector with a sealing protection function, comprising a detachably connected connector 1 and a connector seat 2, the through hole at the top of the connector 1 being detachably connected to a connecting sleeve 201 through an internal thread groove 101, the connecting sleeve 201 being fixedly connected to the bottom end of the connecting seat 2, the through hole of the connector 1 and the inner side of the connecting sleeve 201 being respectively provided with two adaptable connecting wires 3, the top of the connector 1 being provided with a sealing ring groove 102, the bottom end of the connecting seat 2 being provided with a sealing ring 202, and the sealing ring 202 being adapted to the sealing ring groove 102, the upper part of the connector 1 being slidably connected to a sealing cylinder 402, the outer side of the sealing cylinder 402 being provided with a sealing ring 403, the bottom end of the connecting seat 2 being provided with a sealing sleeve 5, the inner side of the sealing sleeve 5 being provided with a sealing ring groove 501, and the sealing ring groove 501 being adapted to the sealing ring 403. The present invention forms an inner seal through the connecting sleeve 201, a middle seal through the cooperation of the sealing ring 202 and the sealing ring groove 102, and an outer seal through the cooperation of the sealing cylinder 402 and the sealing sleeve 5, and the sealing ring 403 and the sealing ring groove 501. The present invention utilizes a three-layer, easily removable sealing structure to optimize the sealing performance of the electrical connector while also facilitating disassembly.
[0023] Furthermore, the connector 1 is rotatably connected to the connecting wire 3, the connecting base 2 is embedded and connected to another connecting wire 3, and the two connecting wires 3 are plugged in. In the present invention, the connecting wire 3 of the connecting base 2 drives the connecting wire 3 of the connector 1 to rotate, thereby not affecting the connection between the connector 1 and the connecting base 2.
[0024] As another embodiment of the present invention, in order to make the sealing cylinder 402 easier to push and facilitate the use of force, as shown in FIG. Figure 4 The present invention discloses the structure of the connection between the connector 1 and the sealing cylinder 402. A sliding groove 4 is defined at the center of each of the six sides of the hexagonal prism structure. Sliders 401 are slidably connected within the sliding grooves 4. Six sliders 401 are fixedly connected to the sealing cylinder 402. By adapting the sealing cylinder 402 to the hexagonal prism at the top of the connector 1, the present invention allows the sealing cylinder 402 to move linearly within the top of the connector 1, preventing rotation. When the sealing cylinder 402 is pushed, it does not rotate, making it easier to bear force and convenient for pushing and pulling.
[0025] It is worth noting that the six sides of the hexagonal prism structure are each provided with a slide groove 4 at the center, wherein a slider 401 is slidably connected to the slide groove 4. The six sliders 401 are welded to the sealing cylinder 402. In the present invention, the slider 401 slides in the slide groove 4, allowing the sealing cylinder 402 to slide linearly on the upper part of the connector 1.
[0026] As another embodiment of the present invention, in order to improve the airtightness of the connection between the connector 1 and the connector base 2 and prevent the connector 1 and the connector base 2 from loosening, as shown in FIG.

The side of the bottom end of the snap block 601 away from the blocking block 6 is set as an arc surface 602, and the top of the snap block 601 is set as a plane. A blocking ring 603 is provided in the through hole of the connecting head 1, and the blocking ring 603 is adapted to the blocking block 6. The present utility model limits the relative movement of the blocking block 6 and the blocking ring 603 by cooperating with the snap block 601 and the blocking ring 603 during connection, thereby preventing the loosening of the connecting seat 2 and the connecting head 1, and improving the air tightness through the cooperation of the blocking block 6 and the blocking ring 603. The present utility model sets a sealing structure on the inner side of the connecting head 1 and the connecting seat 2, while limiting the movement of the connecting seat 2 and the connecting head 1, avoiding the loosening of the connecting seat 2 or the connecting head 1, thereby improving the air tightness.
[0027] Working principle: This embodiment provides an electrical connector with a sealing protection function. When in use, the connecting base 2 is inserted into the connecting head 1, the connecting wire 3 in the connecting head 1 is rotated to match the position of the connecting wire 3 in the connecting base 2, and then the connecting wire 3 is plugged in. The connecting base 2 cooperates with the internal thread groove 101 in the through hole of the connecting head 1 through the connecting sleeve 201 and is fixed on the connecting head 1. At the same time, the sealing ring 202 is inserted into the sealing ring groove 102, and the sealing block 6 is inserted into the sealing ring 603 through the snap block 601. Then the sealing cylinder 402 is slid, the sealing cylinder 402 is inserted into the sealing sleeve 5, and the sealing ring 403 is inserted into the sealing ring groove 501 to complete the connection between the connector 1 and the connecting base 2.
