Description
Technical Field
[0001] This utility model relates to the field of socket manufacturing technology, specifically a waterproof socket structure. Background Technology
[0002] Waterproofing national standard sockets has always been a major challenge. Existing waterproof structures mostly use rubber seals. For example, the waterproof structure disclosed in patent application CN202320981502.1, entitled "Waterproof Socket," includes a housing with a front cover and a bottom cover. The bottom cover is detachably connected to the front cover. The waterproof socket also includes a third waterproof part (i.e., a rubber sealing ring). This third waterproof part is constructed as a soft, elastic structure and connects between the front cover and the bottom cover to seal the gap between them. Like most existing socket structures, it uses a single-layer sealing ring between the front and bottom covers. However, the waterproofness and reliability of this structure are very limited, therefore, its structure needs further improvement. Utility Model Content
[0003] The purpose of this utility model is to overcome the above-mentioned deficiencies and to disclose to the public a waterproof socket structure with a reasonable structure that can effectively improve waterproof sealing.
[0004] The technical solution of this utility model is implemented as follows:
[0005] A waterproof socket structure includes a housing, within which a power receiving module and a circuit board are disposed, and a power cord is disposed on the circuit board. The housing includes a base and a top cover. A baffle plate is vertically disposed on the base, and a cavity is formed within the baffle plate. The power receiving module and the circuit board are placed within the cavity. A first sealing element is disposed between the top of the baffle plate and the top cover. A second sealing element is disposed between the base and the top cover on the outer periphery of the baffle plate. A waterproof sealing assembly is disposed between the power cord and the housing.
[0006] Further optimization measures for this technical solution are as follows:
[0007] As an improvement, a sealing groove is provided inside the upper cover, and the first sealing element is placed inside the sealing groove. The sealing groove facilitates the installation of the first sealing element.

[0035] like Figures 1 to 10 As shown, a waterproof socket structure includes a housing, within which a power receiving module 1 and a circuit board 2 are disposed. A power cord 3 is disposed on the circuit board 2. The housing includes a base 4 and a top cover 5. A baffle plate 41 is vertically disposed on the base 4, and a cavity 4a is formed within the baffle plate 41. The power receiving module 1 and the circuit board 2 are placed within the cavity 4a. A first sealing element 61 is disposed between the top of the baffle plate 41 and the top cover 5. A second sealing element 62 is disposed on the outer periphery of the baffle plate 41 between the base 4 and the top cover 5. A waterproof sealing assembly is disposed between the power cord 3 and the housing.
[0036] The power connection module 1 is existing technology, namely a socket module with conductive parts inside that cooperate with the plug.
[0037] The upper cover 5 is provided with a sealing groove 5a, and the first sealing element 61 is placed in the sealing groove 5a.
[0038] The upper cover 5 has a stepped surface 5b on its outer periphery. When the upper cover 5 and the base 4 are closed, the second sealing member 62 abuts against the stepped surface 5b for sealing.
[0039] The enclosure plate 41 is provided with a groove 41a for the power cord 3 to pass through.
[0040] After the power cord is inserted through the mounting hole of the top cover 5, it is placed in the groove 41a of the baffle plate 41. The groove 41a is designed to facilitate the assembly of the socket.
[0041] The second sealing element 62 is provided with a through hole 62a for the fixing screw 7 to pass through. The upper cover 5 and the base 4 are fixed by the fixing screw 7. When fixed, the fixing screw 7 passes through the through hole 62a on the second sealing element 62. This setting can play a positioning role and prevent the second sealing element 62 from shifting when the upper cover 5 and the base 4 are fixed.
[0042] The waterproof sealing assembly includes an inner sealing ring 81, a constricted part 82, and an outer fixing part 83 arranged sequentially from the inside to the outside. The outer side of the inner sealing ring 81 is provided with a conical surface 81a, the outer side of the constricted part 82 is provided with a constricted part 82a, and the outer fixing part 83 is fixed to the upper cover 5.
[0043] The constricted portion 82a is composed of a plurality of spaced elastic portions 82b.
[0044] The external fixing member 83 is fixed to the upper cover 5 by screws. As the screws are tightened, the external fixing member 83 compresses the constricted portion 82a of the constricted part 82, so that the constricted portion 82a hugs the power cord 3. At the same time, the constricted part 82 presses the conical surface 81a of the inner sealing ring 81, so that the inner sealing ring 81 and the power cord 3 are in sealed contact, thereby ensuring the waterproof seal between the power cord 3 and the outer shell.
[0045] A third sealing element 63 is provided between the top surface of the power receiving module 1 and the upper cover 5. The third sealing element 63 ensures the sealing between the power receiving module 1 and the upper cover 5, thereby improving the waterproof sealing performance of the socket.
[0046] The outer casing is provided with a switch button assembly 9, which includes a directionally adapted inner button bracket 91 and a silicone button 92, and a button reinforcement 93 is provided between the inner button bracket 91 and the silicone button 92.
[0047] The outer periphery of the inner support 91 of the button is provided with a snap-fit part 91a, and an annular groove 91b is formed on the inner side of the snap-fit part 91a. The lower part of the silicone button 92 is placed in the annular groove 91b, and the snap-fit part 91a is fixed to the upper cover 5. The outer periphery of the silicone button 92 is provided with an annular cavity 92a, and the edge of the mounting hole of the upper cover 5 is embedded in the annular cavity 92a.
[0048] After the switch button assembly 9 is assembled, the button reinforcement 93 is placed between the inner button bracket 91 and the silicone button 92. The lower part of the silicone button 92 is placed in the annular groove 91b. Then, the inner button bracket 91 is fixed to the upper cover 5 by the snap fastener 91a. As the snap fastener 91a is engaged, the edge of the mounting hole of the upper cover 5 is embedded in the annular cavity 92a. This design ensures the waterproof sealing of the switch button assembly 9.
[0049] This utility model discloses a waterproof socket structure with a reasonable structure. It isolates the installation space of the power module 1 and the circuit board 2 through the setting of the baffle plate 41. A first sealing element 61 is set at the top of the baffle plate 41, and a second sealing element 62 is set on the outer periphery of the baffle plate 41. When the upper cover 5 and the base 4 are closed, the first sealing element 61 is located between the base 4 and the upper cover 5 and is located in the sealing groove 5a of the upper cover 5. The second sealing element 62 is located between the base 4 and the upper cover 5 and abuts against the stepped surface 5b of the upper cover 5. Due to the setting of the baffle plate 41, there is a height difference between the first sealing element 61 and the second sealing element 62 in the longitudinal direction, thereby forming a stepped double-layer sealing structure, which can effectively improve the waterproof sealing performance of the socket.
[0050] In addition, the new national standard for sockets has added a pressure test. When the socket body is subjected to external pressure, the outer shell may undergo slight deformation. This utility model provides a waterproof socket structure with a baffle plate 41 on the base 4. When the top cover 5 is closed, it is located outside the baffle plate 41, forming a double-layer structure that improves the overall strength of the socket. Simultaneously, the stepped double-layer sealing structure increases safety redundancy and effectively improves the reliability of the seal compared to the single-seal ring structure of existing sockets.
[0051] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
