Description

Technical Field

[0001] This utility model relates to the field of socket technology, and in particular to a multi-hole socket with high sealing performance. Background Technology

[0002] A multi-socket socket is a power supply device with multiple sockets. It can power multiple appliances simultaneously by connecting to a power source with a single plug. It is widely used in homes, offices, and other places, and has the advantages of saving space and being easy to use. Some models also have safety functions such as overload protection, lightning protection, and independent switches.

[0003] Existing multi-socket sockets lack effective sealing devices in the socket area. Relying solely on simple plastic covers or ordinary dust plugs, they cannot form a tight seal. Once exposed to humid or dusty environments for a long time, dust and moisture can easily seep into the socket, causing poor contact, short circuits, or even corrosion. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a multi-hole socket with high sealing performance. It has excellent sealing performance, effectively prevents moisture, dust and foreign objects from entering the socket area, improves the overall protection level, and is suitable for complex environments with high humidity and dust.

[0005] To solve the above-mentioned technical problems, this utility model provides a multi-hole socket with high sealing performance, including a housing, a plurality of socket assemblies on the housing, a mounting base inside the housing, and the plurality of socket assemblies mounted on the mounting base. Each socket assembly includes a socket body, a grounding contact piece passing through the socket body, and a socket hole on the socket body. The mounting base has a conductive connection part, and the socket hole corresponds one-to-one with the conductive connection part. The socket body has a sealing element, and the sealing element has a cover. The side wall of the sealing element has a sealing ring integrally formed therewith. The sealing ring includes a support part, and the support part has a flexible sealing part that abuts against the cover.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0029] according to Figures 1 to 5As shown, this utility model discloses a multi-hole socket with high sealing performance, comprising a housing 1, on which multiple socket assemblies 2 are provided. A mounting base 3 is provided inside the housing 1 for mounting and fixing the multiple socket assemblies 2. Each socket assembly 2 includes a socket body 4, on which a grounding contact 5 passes. A conductive connection portion 7 is provided inside the mounting base 3, and a socket hole 6 corresponding to the conductive connection portion 7 is provided on the socket body 4 to achieve electrical conduction. To improve the sealing effect, a sealing element 8 is provided on the socket body 4. A sealing ring 10 is integrally formed on the side wall of the sealing element 8. The sealing ring 10 includes a support portion 11, on which a flexible sealing portion 12 is provided. The flexible sealing portion 12 bends away from the cover body 9 and can effectively fit the cover body 9 during use, preventing external impurities from entering the socket hole 6 area. A limiting ring 13 is also provided on the cover body 9 to limit the range of motion of the sealing ring 10. The end of the limiting ring 13 away from the cover body 9 has a first inclined portion 14, and the end closer to the cover body 9 has a second inclined portion 15, which together form a trapezoidal structure. When the cover 9 is opened, the flexible sealing part 12 on the sealing ring 10 is guided by the limiting ring 13, slides along the first inclined part 14 and gradually leaves the surface of the cover 9, so that the sealing structure is gradually released, which is conducive to smooth opening; when the cover 9 is closed, the flexible sealing part 12 gradually returns to its original position along the second inclined part 15 and adheres to the surface of the cover 9, achieving a tighter press seal through the deformation of the inclined part.

[0030] In addition, there are three sets of socket components 2, which are securely installed by the first clip 16 located on the upper end of the mounting base 3 and the second and third clips 18 on both sides, making it easy to disassemble and replace.

[0031] A rotating shaft 19 is provided on one side of the housing 1, and a rotating part 20 is provided on the cover 9 to cooperate with it. The rotating part 20 is rotatably mounted on the rotating shaft 19 to form a flip cover structure. A torsion spring 32 is provided between the rotating part 20 and the rotating shaft 19 to provide elastic force for automatic reset, so that the cover 9 can automatically close when not in use. A limiting arm 21 is also provided on the cover 9 to limit the position during the rotation of the cover 9 and avoid excessive rotation that could cause structural damage.

[0032] according to Figure 6 As shown, the mounting base 3 also includes a protective kit 22, which comprises a base 23 and a mounting shaft 24 mounted thereon. A rotatable protective cover 25 is mounted on the mounting shaft 24 to provide cover when the plug is not inserted, preventing foreign objects from entering. The protective cover 25 has an arcuate portion 26 corresponding to the position of the socket 6.

A return spring 27 is provided on one side of the protective cover 25, which automatically drives it back to the covered position after the plug is removed, maintaining a sealed state.

[0033] To ensure a stable connection between the seal 8 and the socket body 4, the seal 8 is provided with a mounting protrusion 28, and the socket body 4 is provided with a matching slot 29. During installation, the protrusion is inserted into the slot 29 to achieve fixation.

[0034] according to Figure 7 As shown, the socket body 4 is also provided with a guide block 30, which cooperates with the guide groove 31 on the housing 1, so that the socket assembly 2 can move smoothly along the guide groove 31 during installation, thereby improving the ease of installation.

[0035] When in use, with no plug inserted, the socket cover 9 is closed. Simultaneously, the flexible sealing part 12 below the cover 9 adheres to the inner wall of the cover 9, bending inwards to provide resilience and improve fit and sealing. The protective cover 25 under the socket is also closed. When the user needs to use the socket, they manually open the cover 9. The rotating part 20 drives the cover 9 to rotate and open. At this time, the flexible sealing part 12 gradually slides, deforms, and leaves the surface of the cover 9 under the guidance of the first inclined part 14 of the limiting ring 13, releasing the sealing structure. The plug pushes the arc-shaped part 26 of the protective cover 25, causing the protective cover 25 to rotate around the mounting shaft 24, making room for the socket 6. After the plug is successfully inserted, the socket 6 on the socket body 4 contacts the conductive connection part 7 in the mounting base 3, achieving conductivity. The grounding piece on the plug is connected to the grounding contact piece 5 in the socket body 4, ensuring electrical safety. When the plug is unplugged, the protective cover 25 automatically resets under the action of the reset spring 27, restoring the cover to the socket 6; the cover 9 automatically rotates back under the drive of the torsion spring 32, and the flexible sealing part 12 is guided along the second inclined part 15 of the limiting ring 13 to automatically adhere back to the surface of the cover 9, the sealing structure is re-pressed, and the initial protective state is restored.

[0036] The beneficial effects of this utility model are:

[0037] This invention boasts superior sealing performance, effectively preventing moisture, dust, and foreign objects from entering the socket area, thus enhancing the overall protection level and making it suitable for complex environments characterized by humidity and dust.

[0038] This invention automatically covers the socket when the plug is not inserted, effectively preventing foreign objects from entering and greatly improving safety.

[0039] The sealing structure allows for automatic closure, eliminating the need for manual resetting and making it more convenient to use, thus preventing contamination or damage caused by forgetting to close the lid.
