Therefore, the directional and positional terms used are intended to illustrate and facilitate understanding of this invention and are not intended to limit the scope of protection of this invention.
[0028] like Figures 1 to 6 As shown in FIG. 1 , an embodiment of the present invention is an expansion socket with a USB interface, comprising a socket body 1 and an interface 2 and a plug 3 provided on the socket body 1 , the plug 3 being used to be inserted into a wall socket, the interface 2 being used to electrically connect an electrical appliance, and a socket shell 4 and a waterproof component for shielding the interface 2. The socket shell 4 is connected to the socket body 1 by a snap 5, and a socket 6 is provided on the end surface of the socket shell 4 corresponding to the position of the interface 2. The waterproof component comprises a mounting frame 7, a connector 8 and a cover plate 9 connected in sequence. A ring platform 10 is raised on the inner edge of one end of the socket body 1 connected to the socket shell 4, the mounting frame 7 is sheathed on the outside of the ring platform 10, and the mounting frame 7 is fixed to the socket body 1 by snapping the socket shell 4. A groove 11 for snapping the cover plate 9 is recessed on the end surface of the socket shell 4 corresponding to the socket 6, and the cover plate 9 snaps into the groove 11 while shielding the socket 6.
[0029] The beneficial effects of this arrangement are as follows: the present invention protects the interface on the expansion socket through a waterproof assembly. The cover of the waterproof assembly can be snapped into the groove of the socket shell to simultaneously cover the jack and the interface. The groove is used to fix the cover to prevent water splashing and causing a short circuit in the socket. The cover is also connected to the installation frame via a connector. The installation frame is clamped and fixed between the socket shell and the socket body. The ring further limits the installation frame, facilitating installation. The waterproof assembly is easily installed on the expansion socket. When the interface is needed, the cover is removed. The cover is connected via the connector and is not easily lost, allowing for flexible use. The socket body 1 also has a circuit board 21 inside. The interface 2 and plug 3 are both electrically connected to the circuit board 21.
[0030] It is further provided that the end surface of the cover plate 9 is raised with a boss 12 adapted to the groove 11 .
[0031] The beneficial effects of such a setting are as follows: the boss increases the contact area between the cover plate and the groove, making the fastening more secure and improving the waterproof capability.
[0032] It is further provided that an inserting block 13 for inserting into the interface 2 is protruded from the boss 12 .
[0033] The beneficial effects of this arrangement are as follows: when the cover is fastened to the socket housing, the insert extends into the interface, which can prevent foreign matter from entering the interface. While protecting the interface, it also increases friction to prevent the cover from loosening.
[0034] It is further provided that a shift block 14 extends from the edge of the cover plate 9 .
[0035] The beneficial effect of this arrangement is as follows: the cover plate can be removed from the socket housing more easily by using the shift block.
[0036] It is further provided that an anti-slip pattern 15 is raised on the end surface of the shift block 14 .
[0037] The beneficial effects of this setting are as follows: the anti-slip texture increases the friction when moving the shift block, making it easier to remove the cover and saving more effort.
[0038] It is further provided that the outer edge of the ring platform 10 is provided with an oblique conical surface 16 .
[0039] The beneficial effect of this arrangement is as follows: the inclined conical surface allows the mounting frame to slide off the ring platform during assembly, thereby improving assembly efficiency.
[0040] It is further provided that four clips 5 are provided on the socket shell 4, and the four clips 5 are distributed in pairs on both sides of the socket shell 4. Four card slots 17 adapted to the clips 5 are opened at one end of the socket body 1 close to the ring platform 10, and the four card slots 17 are also distributed in pairs on both sides of the socket body 1.
[0041] The beneficial effects of this arrangement are as follows: the snap-fit structure between the buckle and the slot is both convenient for assembly and disassembly and securely fixed.
[0042] Furthermore, a pressing block 18 is provided on the side wall of the socket body 1 , and a wedge-shaped pattern 19 is provided on the outer wall of the pressing block 18 .
[0043] The beneficial effects of this setting are as follows: the pressing block provides a force point when the extension socket is plugged in and unplugged from the wall socket. There are pressing blocks on both sides, which provide uniform force, make plugging and unplugging easier, prevent the plug from tilting, and the wedge-shaped texture increases friction.
[0044] It is further provided that the socket housing 4 is provided with a side opening 20 for the connecting member 8 to pass through.
[0045] The beneficial effects of such a configuration are as follows: the socket shell is tightly fastened to the socket body, and the side opening is only for the connector to extend out, thereby protecting the stable installation of the mounting frame.
[0046] It is further configured that the interface 2 includes a USB interface and a Type-C interface, and the connector 8 is made of an elastic or flexible material.
[0047] The beneficial effects of this setting are as follows: the interface can adopt USB interface and Type-C interface, etc., which is convenient for connecting multiple electrical appliances at the same time, and different types of interfaces enrich the electrical connection methods. The connector uses elastic or flexible materials and can be twisted and stretched at will, which is convenient for driving the cover to be fastened and removed, and the cover has a higher degree of freedom.
[0048] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
