[0014] Example 1.

[0015] Please see Figures 1 to 7 The present invention provides a waterproof adapter, comprising an upper cover plate 1, a lower cover plate 2, a welding part 3, and an adhesive part 4; The lower cover plate 2 includes a lower housing 21 and a surrounding plate 22, and the upper cover plate 1 is connected to the lower housing 21 to form a sealed cavity; The welding section 3 is located at the intersection of the upper cover plate 1 and the lower housing 21 and welds the upper cover plate 1 and the lower housing 21 together; The enclosure 22 originates from the outer wall of the lower housing 21 and extends away from the lower housing 21, and the enclosure 22 extends toward the upper cover 1. The enclosure 22 is spaced apart from the upper cover 1 and the lower housing 21 to form a receiving groove 23. The adhesive part 4 is disposed in the receiving groove 23 and connects the upper cover 1 and the lower cover 2.

[0016] Specifically, in this embodiment, the upper cover plate 1 has an upper cavity, and the lower shell 21 has a lower cavity. After the upper cover plate 1 and the lower shell 21 are closed, the upper cavity and the lower cavity form a sealed cavity. Preferably, the contact surfaces of the upper cover plate 1 and the lower shell 21 are welded together to form a welded part 3, thereby achieving a seamless connection. The surrounding plate 22 starts from the outer surface of the lower shell 21 and extends in a direction away from the outer surface and towards the upper cover plate 1. The upper surface of the surrounding plate 22 extends beyond the upper surface of the lower shell 21. The distance between the surrounding plate 22 and the combination of the lower shell 21 and the upper cover plate 1 forms a receiving groove 23. The combination of the upper cover plate 1 and the lower cover plate 2 is placed in an injection mold for secondary molding. After injecting glue into the receiving groove 23 and cooling, a glue part 4 is formed. The glue part 4 bonds the upper cover plate 1 and the lower shell 21, thereby achieving a further sealing effect and achieving the purpose of waterproof sealing.

[0017] By providing a surrounding plate 22 on the outer surface of the lower housing 21, the surrounding plate 22 starts from the outer surface of the lower housing 21 and extends away from the surrounding plate 22 and towards the upper cover plate 1. The spacing between the surrounding plate 22 and the combination of the upper cover plate 1 and the lower housing 21 forms an accommodating groove 23. The welding part 3 welds the intersection of the upper cover plate 1 and the lower housing 21, and the adhesive part 4 bonds the upper cover plate 1 and the lower housing 21, achieving a double-layer sealing effect, achieving the purpose of waterproof sealing, and meeting the application requirements of high waterproofing.

The protruding ring portion 11 is embedded in the inner ring groove 211, and the inner ring groove 211 is recessed on the upper surface of the lower housing 21. The protruding ring portion 11 is embedded in the inner ring groove 211, which improves the connection firmness and assembly accuracy between the upper cover plate 1 and the lower housing 21, and at the same time increases the contact surface between the welding part 3 and the lower housing 21 and the upper cover plate 1, thereby improving the sealing effect.

[0019] The waterproof adapter also includes an indicator light 5. The upper cover plate 1 has a through hole 12 and a light guide post 13. The through hole 12 penetrates the upper cover plate 1 along its thickness direction. The light guide post 13 is located on the upper cover plate 1 and inside the sealed cavity. The central axis of the light guide post 13 coincides with the central axis of the through hole 12. The light guide post 13 is fixedly connected to the through hole 12. The indicator light 5 is located on the light guide post 13. The indicator light 5 helps users distinguish between charging and charging completed states. Preferably, after the upper cover plate 1 with the through hole 12 is formed, the upper cover plate 1 is then formed a second time to inject the transparent light guide post 13 onto the upper cover plate 1, so that the light guide post 13 is located below the through hole 12, making the light guide post 13 integrally formed with the upper cover plate 1, further improving the waterproof sealing effect. The light guide post 13 has a small hole to facilitate the electronic end of the indicator light 5 to extend into the sealed cavity and communicate with the electronic components inside the adapter, realizing the indication effect of the indicator light 5.
