[0030] As a further implementation of the present invention, a plurality of exhaust grooves 6 are provided, and the length of the exhaust grooves 6 is half the length of the pin 7. When the sealing plate 51 and the exhaust grooves 6 overlap in vertical projection, the gas between the sealing plate 51 and the connector movable end 3 will be discharged through the exhaust grooves 6.

[0031] As a further implementation scheme of the present scheme, a plurality of connecting rods 71 ​​are provided, the connecting rods 71 ​​are parallel to each other, the top end of the connecting rod 71 is arc-shaped, the angle between the connecting rod 71 and the sealing plate 51 is 90°, the square hole 72 and the circular hole 75 are both connected to the center hole 74, two square holes 72 and two circular holes 75 are provided, the end of the conductive pad 73 away from the center hole 74 is pitted, the vertical cross-section size of the conductive pad 73 and the middle position of the square hole 72 is equal, through the above-mentioned arrangement of the pin 7, when the vertical projection position of the sealing plate 51 and the exhaust groove 6 does not overlap, the gas between the sealing plate 51 and the movable end 3 of the connector will enter the center hole 74 through the circular hole 75, thereby deforming the conductive pad 73 fixedly connected to the inside of the square hole 72, and stably connecting it to the female plug inside the fixed end 1 of the connector, so as to ensure the stability of signal transmission.
