[0024] Figure 1 : is an exploded view of the sealing joint of the embodiment of the present application. Figure 1 As described above, embodiments of the present application provide a novel sealed joint, comprising a first joint 1 and a second joint 2. The first joint 1 and the second joint 2 are each connected to a cable. When the first joint 1 and the second joint 2 are connected, a circuit is established. The connection between the first joint 1 and the second joint 2 is provided by a novel sealing structure, achieving a secure seal and a simple structure.

[0025] Figure 2 This is a structural diagram of the first connector in the embodiment of the present application. Figure 2 As shown, the first connector 1 includes a first body 11 and a conductive pin 12. In this embodiment, the first body 11 is truncated cone-shaped and is made of PPS (polyphenylene sulfide) plus GF (glass fiber) material. The conductive pin 12 is embedded in the first body 11, and one end extends out of the upper surface of the first body 11. The end of the conductive pin 12 embedded in the first body 11 is used to connect to the cable, and the end extending out of the upper surface of the first body 11 is used to connect to the second connector 2. In this embodiment, the conductive pins 12 are copper pins, and there are three of them. The number can also be increased or decreased according to the situation.

[0026] A first ring-shaped sealing ring 13 is provided on the upper surface of the first body 11. The conductive pin 12 is positioned within the ring, passing through the inner circle of the ring. When the first connector 1 is connected to the second connector, the ring acts as a seal, preventing the conductive pin 12 from coming into contact with water. The ring can be integrally formed with the first body 11.

[0027] The outer wall of the conductive pin 12 is covered with a sealing column 14. The sealing column 14 covers the conductive pin 12, which can further prevent the conductive pin 12 from contacting water and ensure the waterproof performance of the sealed joint. The height of the sealing column 14 does not affect the connection between the conductive pin 12 and the second connector 2.

[0028] Figure 3 This is a structural diagram of the second connector in the embodiment of the present application. Figure 4This is a partial enlarged view of the jack in the embodiment of the present application. Figure 3 and 4 As shown, the second connector 2 includes a second body 21 and a conductive pin holder 23. The second body 21 is provided with a socket 22 corresponding to the conductive pin 12. The conductive pin holder 23 is fully embedded in the socket 22, meaning that the bottom end of the conductive pin holder 23 is a certain distance from the bottom opening of the socket 22. One end of the conductive pin holder 23 is connected to an external cable, and the other end is used to connect to the conductive pin 12. When the conductive pin 12 is inserted into the socket 22 and contacts the conductive pin holder 23, the first connector 1 and the second connector 2 are electrically connected.

[0029] The second body 21 can be made of TPU (Thermoplastic polyurethanes) by injection molding. The conductive needle seat 23 and the cable 24 are welded, and the conductive needle seat 23 is embedded in the second body 21 and then vulcanized to obtain the second connector 2.

[0030] Figure 5 This is a partial enlarged view of the connection between the first connector and the second connector in the embodiment of the present application. Figure 5 As shown, when the conductive needle 12 is inserted into the conductive needle seat 23, the first sealing ring 13 contacts the bottom surface of the second connector 3, which has a flat surface. The first sealing ring 13 is tightly pressed against the bottom surface of the second connector 3, forming a first waterproof seal. When the conductive needle 12 is inserted into the conductive needle seat 23, the sealing post 14 follows and enters the insertion hole 22. The outer wall of the sealing post 14 contacts the inner wall of the insertion hole 22, and the two are tightly fitted together, forming a second waterproof seal.

[0031] When using the sealing joint of this embodiment, the first joint 1 can be fixed to the equipment requiring waterproof sealing. The first joint 1 is connected to the second joint 2 to achieve electrical connection between the electrical components inside the equipment and the components outside the equipment. The sealing joint has a simple structure, is easy to install, and has low manufacturing cost. The two waterproof seals ensure the safety of the internal electrical components.

[0032] Optionally, in this embodiment, the bottom surface of the sealing column 14 is connected to the upper surface of the first body 11, and the two can be integrally formed. When manufacturing the first connector 1, the conductive pin 12 is used as an insert, and the first body 11, the first sealing ring 13, and the sealing column 14 are integrally formed by injection molding.

[0033] As an optional solution, a sealing protrusion 221 is provided on the inner wall of the socket 22, extending along the circumference of the inner wall. When the conductive needle 12 is inserted into the conductive needle holder 23, the outer wall of the sealing post 14 contacts the sealing protrusion 221. Passing through the sealing protrusion 221, the conductive needle 12 and the sealing post 14 fit more tightly together, improving the waterproof performance of the sealed joint.

[0034] In the above sealing joint, there are multiple sealing protrusions 221, which are arranged in a vertical direction to further improve the waterproof effect of the sealing joint. In this embodiment, the number of sealing protrusions 221 is two, but this application is not limited to this.

[0035] Optionally, a first external thread 15 is provided on the side wall of the first body 11.
