[0024] See Figure 1 and Figure 3 As shown, this application proposes an electrical connector with a waterproof cover, comprising: a socket 1, one end of which is provided with a socket; a waterproof cover 6, which is used to seal the socket; and a threaded sleeve 2, which is connected to the waterproof cover 6. The threaded sleeve 2 is provided with an internal thread section 22, and the socket 1 is provided with an external thread section that adapts to the internal thread section 22.

[0025] The socket 1 serves as the structural basis for an electrical connector with a waterproof cover. All other components of the waterproof-covered electrical connector are directly or indirectly mounted on the socket 1. The other end of the socket 1, where the socket has a prong, is embedded within a panel or other socket 1 mounting component. The waterproof cover 6 is used to seal the prong, and the threaded sleeve 2 is used to install the waterproof cover 6 onto the socket 1, thus sealing the prong.

[0026] Specifically, when socket 1 is idle or in a reserved use state, by screwing the threaded sleeve 2 onto one end of socket 1 where the socket is set, the waterproof cover 6 is used to seal the socket, ensuring that the socket of socket 1 is sealed and dry, preventing the socket of socket 1 from being contaminated, thereby improving the safety of the electrical connector and preventing the socket of socket 1 from being damaged due to contamination.

[0027] Preferably, the socket 1 is provided with a marking strip groove 103, which is used to fill the brightly colored marking strip. When the threaded sleeve 2 can completely cover the marking strip and cannot be screwed in, it is determined that the threaded sleeve 2 has been installed in place. When the threaded sleeve 2 cannot be screwed in but does not completely cover the marking strip, it is determined that it is not installed in place. At this time, it is necessary to adjust the angle of the threaded sleeve 2 and check the structure of the internal thread section 22 on the threaded sleeve 2 and the structure of the external thread section on the socket 1.

[0028] The waterproof cover 6 and the threaded sleeve 2 are made of corrosion-resistant alloys such as stainless steel, which have good mechanical properties and excellent corrosion resistance, helping an electrical connector with a waterproof cover to adapt to various harsh operating environments.

[0029] See Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, the device further includes: an abutment portion 62, which is disposed on the waterproof cover 6, and a threaded sleeve 2 having an abutment surface 21 adapted to the abutment portion 62. The contact between the abutment portion 62 and the abutment surface 21 achieves a limiting position of the waterproof cover 6 relative to the threaded sleeve 2 in one vertical direction; a retaining groove 63, which is disposed on the waterproof cover 6; and a retaining ring 4, which is disposed in the retaining groove 63 and abuts against the end face of the threaded sleeve 2. The abutment between the retaining ring 4 and the end face of the threaded sleeve 2 achieves a limiting position of the waterproof cover 6 relative to the threaded sleeve 2 in another vertical direction, thereby assembling the waterproof cover 6 onto the threaded sleeve 2.

[0030] In this embodiment, the retaining ring 4 is a C-shaped retaining ring with an opening and a certain degree of elasticity. The waterproof cover 6 extends from the inside of the threaded sleeve 2 and abuts against the threaded sleeve 2 with the abutting part 62. Then, through the deformation of the retaining ring 4, it is inserted into the retaining groove 63, thereby fixing the waterproof cover 6 onto the threaded sleeve 2. Furthermore, it only restricts the relative movement of the waterproof cover 6 and the threaded sleeve 2, but does not restrict their relative rotation. Since parts like the waterproof cover 6 and the threaded sleeve 2 are easily lost during electrical connection use, the loss of the waterproof cover 6 and the threaded sleeve 2 will cause minor economic losses, and the lost waterproof cover 6 and the threaded sleeve 2 may roll into important areas, causing safety accidents. Therefore, an anti-loss chain needs to be installed on the waterproof cover 6 to install the waterproof cover 6 to other structures to prevent the waterproof cover 6 and the threaded sleeve 2 from being lost. The aforementioned anti-loss chain may make it difficult for the waterproof cover 6 to rotate, while the threaded sleeve 2 needs to be screwed onto the socket 1. Therefore, it is necessary to only restrict the relative movement and not restrict the relative rotation.

[0031] See Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, the device further includes: an annular groove 61 disposed on the waterproof cover 6; and sealing rings 7 disposed on the annular groove 61. The cooperation between the sealing rings 7 and the annular groove 61 can improve the sealing performance between the waterproof cover 6 and the socket 1, further ensuring the seal within the socket 1 and improving its reliability. The diameter of the sealing ring 7 is larger than the depth of the annular groove 61. When the waterproof cover 6 is screwed into the socket 1, the sealing ring 7 is deformed under the pressure of the annular groove 61 and the waterproof cover 6 to ensure the sealing performance between the waterproof cover 6 and the socket 1.

[0032] In this embodiment, two or more annular grooves 61 can be arranged at vertical intervals, and each annular groove 61 has a matching sealing ring 7. By arranging multiple annular grooves 61 at vertical intervals, the sealing performance between the waterproof cover 6 and the socket 1 can be further improved.

[0033] See Figure 3 , Figure 4 and Figure 5As shown, in some embodiments, the socket 1 further includes: a first chamfer 101, which is provided at one end of the socket 1 where the socket is located; the first chamfer 101 is used to avoid stress concentration at the outer edge of the socket 1 where the socket is located, and can effectively prevent the outer edge of the socket 1 where the socket is located from scratching the workers. The first chamfer 101 can be either a rounded corner or a beveled corner; and a second chamfer 102, which is provided at one end of the socket 1 where the socket is located. The second chamfer 102 can be either a rounded corner or a beveled corner. Since the diameter of the sealing ring 7 is larger than the depth of the annular groove 61, the second chamfer 102 can guide the sealing ring 7 during the process of screwing the waterproof cover 6 into the socket 1, allowing it to slide in smoothly.

[0034] See Figure 1 , Figure 3 and Figure 5 As shown, in some embodiments, it further includes a chain hole 5, which is disposed in the waterproof cover 6. The chain hole 5 is used to fix the anti-loss chain, and the waterproof cover 6 is installed on other structures through the anti-loss chain to avoid the loss of the waterproof cover 6 and the threaded sleeve 2.

[0035] See Figure 3 and Figure 4 As shown, in some embodiments, it further includes: knurled surface 3, which is disposed on the outer peripheral surface of the threaded sleeve 2. The knurled surface 3 makes it easier for workers to screw the threaded sleeve 2.

[0036] The above description is only a part or preferred embodiment of this application. Neither the text nor the drawings should limit the scope of protection of this application. All equivalent structural transformations made using the content of this application's specification and drawings under the overall concept of this application, or direct / indirect applications in other related technical fields, are included within the scope of protection of this application.
