[0032] Example 1

[0033] Please refer to Figures 1 to 6 As shown, it illustrates the specific structure of a preferred embodiment of the present invention, which is a waterproof socket.

[0034] This type of socket has excellent waterproof performance, with a simple drainage structure and thorough drainage, leaving no water residue.

[0035] This application provides a waterproof socket, including a housing body 10 and a housing cover 20. A first waterproof step 11 is provided on the back edge of the housing body 10, and a second waterproof step 21 is provided on the housing cover 20. The housing cover 20 covers the housing body 10, and the first waterproof step 11 and the second waterproof step 21 abut against each other. A first sealing ring 14 is provided in the wiring hole 12 on the housing body 10. A wire passes through the first sealing ring 14 and is connected to a circuit board 112 inside the housing body 10. A sealing gasket 32 ​​is provided in the mounting groove 114 on the housing body 10. The socket body 30 protrudes from the mounting groove 114 and presses the sealing gasket 32 ​​tightly. The wiring terminals on the socket body 30 are connected to the circuit board 112. A first drainage groove 16 is provided on the housing body 10, and the first drainage groove 16 is located on the outer periphery of the socket body 30. A light guide post 113 is provided on the housing body 10, and the indicator light on the circuit board 112 faces the light guide post 113. In this embodiment, the shell body 10 and shell cover 20 are manufactured using injection molding, resulting in excellent insulation performance. The shell body 10 and shell cover 20 are fixed together with screws, causing the first waterproof step 11 and the second waterproof step 21 to abut against each other. This structure is simple and provides good waterproofing. The wire passes through the first sealing ring 14 on the shell body 10, preventing water from entering the socket through the wire. The socket body 30 can be screwed into the mounting groove 114, pressing the sealing gasket 32 ​​tightly, preventing water from entering the socket through the mounting groove. Simultaneously, this design allows water to drain directly from the outer surface of the socket through the first drainage groove 16, a more thorough drainage method. Therefore, this type of socket incorporates excellent waterproofing measures between the shell cover 20 and shell body 10, between the socket body 30 and mounting groove 114, and between the wire and shell body 10, preventing water from entering the socket. The circuit board 112 is an intelligent charging circuit board 112, specifically, it can be a circuit board 112 equipped with one of the following chips: PW4052 lithium battery charging management chip, PW2303 synchronous buck chip, or PW2303 synchronous buck chip, enabling intelligent management and control. The circuit board 112 is connected to the wiring terminals on the socket body 30 via wires. The light guide column 113 is injection molded onto the shell body 10, and its structure is inherently waterproof. The light from the indicator light on the circuit board 112 is transmitted to the outside through the light guide column 113 for easy observation. Therefore, this type of socket has a simple waterproof structure, good waterproof performance, and a simple drainage structure with no water residue. The socket hole 31 of the socket body 30 is lined with elastic insulating plastic, providing excellent waterproof performance when the plug is inserted into the hole.

[0036] Preferably, a second drainage groove 13 is provided at the outer opening of the wiring hole 12, and a fitting groove 15 is provided on the first sealing ring 14, which is fitted into the wiring hole 12. The fitting groove 15 can be tightly fitted into the wiring hole 12 to improve waterproofing. At the same time, the second drainage groove 13 can promptly drain water from the opening of the wiring hole 12, effectively preventing water residue and further improving waterproofing performance.

[0037] Preferably, a first mounting post 110 is provided inside the housing body 10; a first fastener 111 fixes the circuit board 112 to the first mounting post 110; a hanging ear 17 is provided at the end of the housing body 10. A buffer pad is provided on the positioning post, and the first fastener 111 is a spring screw, which presses the circuit board 112 against the buffer pad. Preferably, a positioning post is provided on the housing cover 20, which passes through the circuit board 112, and a connecting plate 116 connects the inner wall of the housing body 10 and the first mounting post 110. The hanging ear 17 has holes for hanging the socket. The first fastener 111 presses the circuit board 112 against the buffer pad, which provides a certain degree of cushioning for the circuit board 112. This design prevents the socket from being damaged by drops and improves its drop resistance. The buffer pad can be made of elastic silicone or plastic. The positioning post passing through the circuit board 112 improves the firmness of the circuit board 112 installation. The inner wall of the shell body 10 and the connecting plate 116 of the first mounting post 110 can improve the strength of the first mounting post 110 and prevent it from breaking.

[0038] Preferably, a waterproof cover 18 is also elastically hinged to the socket body 30, which can be closed onto the socket body 30. The waterproof cover 18 is installed on the socket body 30 using one of the following methods: spring pivot, spring hinge, or spring hinge shaft. The waterproof cover 18 closing onto the socket body 30 improves its waterproof capability. More preferably, the waterproof cover 18 is provided with a clearance opening to avoid the charging plug cable, so this type of waterproof socket can still be used normally in the rain. When used in the rain, the waterproof socket is suspended, the plug is inserted into the socket hole 31 of the socket body 30, and then the waterproof cover 18 is placed on the socket body 30. At this time, the clearance opening faces downwards, preventing water from falling onto the socket body 30.

[0039] Preferably, the first drainage channel 16 is arranged at an angle, and a water collection channel 115 is provided on the upper side of the socket body 30, which is connected to the upper first drainage channel 16; the lower first drainage channel 16 is connected to the mounting groove 114. Some water on the waterproof socket will fall into the water collection channel 115 and then drain away from the upper first drainage channel 16. The lower first drainage channel 16 will drain the water in the mounting groove 114 in a timely manner, so there will be no water accumulation in the mounting groove 114. The waterproof performance between the socket body 30 and the shell body 10 is also very good, and there will be no water accumulation.

[0040] Preferably, the first sealing ring 14 and the sealing gasket 32 ​​are components made of one of the following materials: silicone, polyurethane, rubber, or elastic plastic.

[0041] Preferably, the shell body 10 and shell cover 20 are accessories manufactured using injection molding or die casting processes, which are simple, efficient, and cost-effective to produce.

[0042] Example 2

[0043] Please refer to Figure 7 As shown, preferably, the housing body 10 is provided with a plurality of hollow heat dissipation pipes 19, through which air can flow. The heat dissipation pipes 19 can be metal pipes, directly injection molded to the housing body 10. Of course, the heat dissipation pipes 19 can also be directly injection molded from the housing body 10. The air flow through the heat dissipation pipes improves the heat dissipation performance inside the waterproof socket, resulting in higher safety. The heat dissipation pipes 19 are coated with an insulating film, and the heat dissipation pipes 19 are insulated from the socket components.

[0044] In summary, the key design feature of this utility model is that, after the waterproof socket is assembled, the first waterproof step 11 and the second waterproof step 21 abut against each other, preventing water from entering the socket from between the shell body 10 and the shell cover 20. The socket body 30 presses the sealing gasket 32 ​​within the mounting groove 114 tightly, preventing water from entering the socket from between the socket body 30 and the mounting groove 114. The wire passes through the first sealing ring 14 on the shell body 10, preventing water from entering the socket from the wire. This type of waterproof socket has good overall waterproof performance and a simple waterproof structure. Furthermore, the first drainage groove 16 is exposed on the surface of the shell body 10, ensuring thorough drainage without residue.
