For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0031] like Figures 1 to 5 As shown, this utility model discloses a connector socket with a sealing and waterproof function, including a housing 1. The housing 1 includes an integrally injection-molded flange end 11 and a mating end 12. The integral injection molding method can avoid secondary assembly and improve assembly efficiency.

[0032] Specifically, the mating end 12 has a signal female terminal slot 13 and a power female terminal slot 14 parallel to its central axis. The signal female terminal slot 13 houses a matching signal female terminal 2, and the power female terminal slot 14 houses a matching power female terminal 3. A plug (not shown in the figure) is provided on one side of the mating end 12, which houses a signal male terminal and a power male terminal. When the plug and the socket are mated, the signal male terminal and the power male terminal are electrically connected to the signal female terminal 2 and the power female terminal 3.

[0033] In this application, both the signal female terminal 2 and the power female terminal 3 have a rubber-coated groove 10, and a rubber-coated ring 19 adapted to the groove 10 is provided. The outer circumferential surface of the rubber-coated ring 19 abuts against the mating end 12. The rubber-coated ring 19 not only achieves precise positioning of the signal female terminal and the power female terminal, but also seals them. This sealing structure eliminates the need for other sealing fixtures, simplifying the assembly structure and reducing costs. Simultaneously, it ensures the sealing performance of the socket, preventing moisture from entering the device and affecting its electrical performance or causing damage.

[0034] Furthermore, the rubber-coated ring 19 is formed within the rubber-coated groove 10 of the signal female terminal 2 and the power female terminal 3. This method achieves an integrated structure of the signal female terminal 2, the power female terminal, and the rubber-coated ring 19, saving a significant amount of manpower in assembling the rubber-coated ring 19. Moreover, the integrated structure of the signal female terminal 2, the power female terminal, and the rubber-coated ring 19 allows for more precise installation and positioning of the rubber-coated ring, thereby improving production efficiency and yield.

[0035] The mating end 12 has a plug portion 121 that mates with a connector plug and a tail portion 122 that mates with a client (not shown). A shielding layer 4 is wrapped around the plug portion 121. The shielding layer 4 has an extension 41 that penetrates the flange end 11 and is fixed to the inner surface 111 of the flange end 11. The shielding layer 4 also includes a shielding sleeve 42 fitted onto the plug portion 121. One end of the shielding sleeve 42 has a bent portion 43, and the other end is fixed with the extension 41. The extension 41 is Z-shaped, and the bent portion 43 is engaged with the plug portion 121. In this configuration, the shielding layer 4 reduces interference from high-frequency electromagnetic waves to the circuit, ensuring that it is not affected by external interference during operation.

[0036] Preferably, a limiting hole 44 is formed on the surface of the shielding sleeve 42, and a latch 45 is provided in the limiting hole 44. The latch 45 is fixed on the shielding sleeve 42 and integrally formed therewith. The latch 45 can abut against the plug part 121 for positioning, which can prevent the shielding sleeve from shifting or moving. In addition, this positioning method is simple, convenient, stable and reliable, greatly improving the working stability and assembly efficiency.

[0037] A sealing groove 5 is provided on the inner side 111. The sealing groove 5 consists of a large sealing groove 52 provided on the outer side of the plug tail 122 and a small sealing groove 53 provided on the outer side of the extension 41. The small sealing groove 53 communicates with the large sealing groove 52. A sealing ring 51 adapted to it is built into the sealing groove 5, and the other side of the sealing ring 51 abuts against the client.

[0038] In this application, since the small sealing groove 53 and the large sealing groove 52 are interconnected, only one sealing ring 51 that matches the outer contour of the sealing groove 5 is needed to achieve assembly sealing. Compared with the prior art where the small sealing groove 53 and the large sealing groove 52 are separate and require sealing rings to be used separately, this reduces the number of parts, greatly improves assembly efficiency, and has a wider range of applicability.

[0039] In this application, the socket also includes a housing 9, which is composed of an integrally formed flange plate 91 and a receiving end 92 disposed on one side of the flange plate 91. The flange plate 91 has insert holes 95 around its perimeter, and insert rings 96 are embedded in the insert holes 95. Locking bolts can pass through the insert rings to lock the flange plate onto the client, achieving a quick connection between the two. This simple and convenient operation greatly improves work efficiency. A limiting post 18 is also provided on the flange end 11. The limiting post 18 can extend and be placed within the limiting hole of the client, serving a limiting and guiding function.

[0040] The flange plate 91 has an inner groove that matches the outer contour of the flange end 11. The flange plate 91 also has a through groove that matches the plug portion 121. The plug portion 121 extends through the through groove and is placed within the receiving space 93 of the receiving end 92. An O-ring 94 is fitted onto the flange end 11, positioned within the receiving groove and abutting against the flange plate 91. The O-ring 94 ensures the sealing performance of the socket, preventing moisture from entering the equipment and affecting its electrical performance or causing damage.

[0041] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0042] The detailed descriptions listed above are merely specific descriptions of feasible implementations of this utility model, and are not intended to limit the scope of protection of this utility model. All equivalent implementations or modifications made without departing from the spirit of this utility model should be included within the scope of protection of this utility model.
