DETAILED DESCRIPTION

[0025] The present application is further described in detail below in conjunction with the accompanying drawings.

[0026] The embodiment of the present application discloses a waterproof and sealed electrical connector.

[0027] Reference Figure 1 The waterproof sealed electrical connector includes a socket 1, which is formed with a socket 2 for inserting the end of a plug, and the socket 1 is integrally formed with a mounting seat 4 located outside the socket 2, and the mounting seat 4 is symmetrically arranged on both sides of the socket 2.

[0028] like Figure 2 , Figure 3 As shown, a latch rod 6 is movably provided on the mounting seat 4, and the end of the latch rod 6 is inserted into the mounting seat 4 from the outer wall of the mounting seat 4, and then passes out from the mounting seat 4 to the outside of the mounting seat 4. A latch groove 60 located outside the mounting seat 4 is coaxially provided on the circumferential outer wall of the end of the latch rod 6, and a limit insert ring 61 is provided on the latch rod 6 through the latch groove 60. The limit insert ring 61 is limited in the latch groove 60, and the limit insert ring 61 and the outer wall of the mounting seat 4 are mutually fitted. The limit insert ring 61 limits the latch rod 6 to be fixed on each mounting seat 4.

[0029] like Figure 2 , Figure 3 As shown, the outer wall of the socket 1 is provided with a waterproof cover plate 3 and a locking member 5 respectively located on the respective mounting seats 4, and the waterproof cover plate 3 and the locking member 5 are arranged opposite to each other. The waterproof cover plate 3 and the locking member 5 are respectively movably sleeved on the outside of their respective latch rods 6, and the waterproof cover plate 3 and the locking member 5 are rotatably arranged on the mounting seat 4 through the latch rod 6. The rotation axes of the waterproof cover plate 3 and the locking member 5 are parallel to each other, and the waterproof cover plate 3 and the locking member 5 are turned around their respective rotation axes in the direction of approaching or moving away from each other.

[0030] like Figure 2 , Figure 3 As shown, a guide groove 40 is provided on the inner wall of the mounting seat 4 and is located on one side of the latch rod 6. The width of the guide groove 40 is adapted to the diameter of the latch rod 6. The latch rod 6 is located in the guide groove 40. After the end of the latch rod 6 is inserted into the mounting seat 4, by inserting the end of the latch rod 6 into the guide groove 40, under the limiting guidance of the guide groove 40, it can be ensured that the end of the latch rod 6 can smoothly pass through the mounting seat 4 to the outside of the mounting seat 4.

[0031] like Figure 2 , Figure 3 As shown, a first torsion spring 30 located in the mounting seat 4 is provided between the waterproof cover plate 3 and the respective opposite latch rods 6, and the first torsion spring 30 is sleeved on the outside of the latch rod 6. One end of the first torsion spring 30 contacts the waterproof cover plate 3, and the other end of the first torsion spring 30 contacts the inner side wall of the mounting seat 4. In a natural state, the first torsion spring 30 is used to push the waterproof cover plate 3 to flip in a direction close to the socket 2 until the waterproof cover plate 3 covers the opening surface of the socket 2.

[0032] like Figure 2 , Figure 3 As shown, a second torsion spring 50 located in the mounting seat 4 is provided between the locking member 5 and the respective opposite latch rods 6. The second torsion spring 50 is sleeved on the outside of the latch rod 6. One end of the second torsion spring 50 contacts the locking member 5, and the other end of the second torsion spring 50 contacts the inner side wall of the mounting seat 4. In a natural state, the second torsion spring 50 is used to push the locking member 5 to flip toward the direction close to the socket 2.

[0033] like Figure 2 , Figure 3As shown, a slot 31 is integrally formed on the outer wall of the waterproof cover plate 3 away from the first torsion spring 30, and a block 51 for engaging with the slot 31 is provided on the outer wall of the locking member 5 away from the second torsion spring 50. When the waterproof cover plate 3 covers the opening surface of the socket 2 under the action of the first torsion spring 30, the locking member 5 will be engaged and fixed with the waterproof cover plate 3 through the engagement of the block 51 with the slot 31 under the action of the second torsion spring 50, thereby locking the waterproof cover plate 3.

[0034] like Figure 2 , Figure 3 As shown, a waterproof sealing pad 7 is fixedly arranged on the side wall of the waterproof cover plate 3 facing the socket 2, and the waterproof sealing pad 7 is made of a rubber material with a certain elastic deformation ability. The socket 1 is integrally formed with a sealing convex edge 10 that is circumferentially distributed on the side wall of the opening surface of the socket 2, and the sealing convex edge 10 is located on the turning path of the waterproof sealing pad 7. When the waterproof cover plate 3 covers the opening surface of the socket 2, the waterproof sealing pad 7 will fit with the side wall of the opening surface of the socket 2, and the sealing convex edge 10 will be pressed into the waterproof sealing pad 7. Through the mutual interference between the sealing convex edge 10 and the waterproof sealing pad 7, the waterproof sealing performance of the socket 2 can be further enhanced.

[0035] like Figure 1 , Figure 2 As shown, a drainage hole 20 is provided on the inner wall of the bottom of the socket 2, and the drainage hole 20 passes through the outer wall of the socket 1. When rainwater accidentally enters the socket 2 due to the waterproof cover 3 being opened, the drainage hole 20 provided at the bottom of the socket 2 can allow the rainwater to be discharged from the socket 2 in time, effectively alleviating the accumulation of rainwater in the socket 2.

[0036] like Figure 3 , Figure 4 As shown, an insulating barrier member 8 located at the end of the signal plug is integrally formed on the side wall of the socket 1 away from the mounting seat 4, and a limiting block 80 is integrally formed on the side wall of the barrier member 8 away from the socket 1. The limiting block 80 is used to contact the outer side wall of the terminal fixedly installed at the end of the signal plug later. The installation position of the terminal is positioned by the limiting block 80 to prevent the terminal from rotating during the installation process. In addition, the creepage distance between adjacent signal plugs can be increased, thereby improving the stability and safety of adjacent signal plugs during signal transmission.

[0037] The implementation principle is: when the waterproof cover 3 covers the opening surface of the socket 2, the waterproof cover 3 is clamped and fixed by the locking member 5. At this time, the waterproof cover 3 can be stably and firmly pressed against the opening surface of the socket 2 under the locking of the locking member 5. Even if the waterproof cover 3 is subjected to external force, the waterproof cover 3 is not easy to separate from the opening surface of the socket 2, thereby ensuring the waterproof sealing performance of the waterproof cover 3 to the socket 2, and the waterproof sealing performance is good, which can effectively prevent rainwater from entering the socket 2.

[0038] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
