For those skilled in the art, the specific meanings of the above terms in the present invention may be understood based on specific situations.

(15) As shown in FIGS. 1 to 8, one embodiment of the present application provides a USB socket, which includes a housing 10, a rubber core 20 and a set of terminals 30. The housing 10 defines a cavity 11 extending through a front end and a rear end of the housing 10. The rubber core 20 is mounted in the cavity 11, and the set of terminals 30 is mounted on the rubber core 20. The set of terminals 30 includes a first contact terminal 31 and a plurality of second contact terminals 32, and the first contact terminal 31 and each of the second contact terminals 32 are arranged side by side. A rear end of the first contact terminal 31 and a rear end of each of the second contact terminals 32 extend out of a rear end of the housing 10. A front end of each of the second contact terminals 32 is exposed out of the rubber core 20 and located within the cavity 11. A front end of the first contact terminal 31 is located below the front end of its adjacent second contact terminal 32. An elastic or variable gap 33 is formed between the front end of the first contact terminal 31 and the front end of the second contact terminals 32. In this way, when a USB plug 40 is plugged into the cavity 11, the front end of the first contact terminal 31 is contacted with the front end of the second contact terminal 32 pressed by the USB plug 40. The USB socket of this embodiment of the present application can make the button controller achieve zero standby state when being not in use, so as to avoid power consumption loss.

(16) In some embodiments of the present application, the USB socket is mounted into the button controller. The first contact terminal 31 is connected with a first ground terminal of an electronic device, and the adjacent second contact terminal 32 is connected with a second ground terminal of the electronic device. When the USB plug 40 is not plugged in the cavity 11, the front end of the first contact terminal 3 of the USB socket is not contacted with the adjacent second contact terminal 32 thereof, so no electrical connection occurs, that is, the first ground terminal is not electrically connected with the second ground terminal. In this way, the button controller with the USB socket cannot realize a full path, and there will be no 5V voltage output. As a result, the button controller achieves the zero standby function. When the USB plug 40 is plugged into the USB socket, the front end of the first contact terminal 31 of the USB socket contacts the front end of the adjacent second contact terminal 32, and thus the electrical connection occurs, that is, the first ground terminal is connected with the second ground terminal. Therefore, the button controller with the USB socket realizes the full path, and there will be 5V voltage output to the USB socket for achieving work.

(17) In some embodiments, as shown in FIGS. 3 to 4 and FIGS. 7 to 8, the front end of the second contact terminal 32 adjacent to the first contact terminal 31 includes a bent elastic portion 322 and a flat abutting portion 321 extending distally from an end of the bent elastic portion 322. The bent elastic portion 322 is exposed on the rubber core 20 and located within the cavity 11, and the elastic or variable gap 33 is formed between the flat abutting portion 321 and the front end of the first contact terminal 31. Specifically, by the arrangement of the bent elastic portion 322 disposed on the front end of the second contact terminal 32 adjacent to the first contact terminal 31, it can be ensured that the bent elastic portion 322 deforms and presses down when being subjected to the pressure of the USB plug 40 plugged in the cavity 11, thereby driving the flat abutting portion 321 extended from the front end of the bent elastic portion 322 down and contact the front end of the first contact terminal 31, so as to realize the electrical connection between the first contact terminal 31 and the second contact terminal 32. Once the USB plug 40 is removed, the force applied to press down the bending elastic portion 322 is also removed, so that the bending elastic portion 322 restores its original state and makes the flat contact portion 321 restore its original state and break away from the abutment of the front end of the first contact 31, thereby achieving a power-off state. There will be no 5V voltage output, so that the button controller achieves the zero standby function. The structural design of the present invention is ingenious, and the practicality is high.

(18) In some embodiments, as shown in FIGS. 3 to 4 and FIGS. 7 to 8, the front end of the first contact terminal 31 extends toward a side of its adjacent second contact terminal 32 to form a base abutting portion 311 configured to contact the flat abutting portion 321, and the elastic or variable gap 33 is formed between the base abutting portion 311 and the flat abutting portion 321. Specifically, the base abutting portion 311 extended from a side of the front end of the first contact terminal 31 can ensure that the front end of the first contact terminal 31 is located below the flat abutting portion 321 of the front end of the adjacent second contact terminal 32 spaced apart from the first contact terminal 31. In this way, although the first contact terminal 31 is spaced apart from the second contact terminal 32, it can still be ensured that the base abutting portion 311 of the first contacting end 31 is located below the flat abutting portion 321 of the second contacting terminal 32, so as to further ensure that the elastic or variable gap 33 is formed between the first contact terminal 31 and the second contact terminal 32. In this way, when the USB socket is not in use, the elastic or variable gap 33 makes the flat abutting portion 321 and the base abutting portion 311 to disconnect from each other. When the USB socket is in use, due to the action of the USB plug 40, the flat abutting portion 321 contacts the base abutting portion 311 to achieve the electrical connection and work.

(19) In some embodiments, as shown in FIG. 5, the rubber core 20 includes a first terminal groove 21 configured to hold the first contact terminal 31 and second terminal grooves 22 configured to hold each of the second contact terminals 32 respectively. The first contact terminal 31 is embedded in the first terminal groove 21, the second contact terminals 32 are embedded in the second terminal grooves 22, and a front end of the first terminal groove 21 is in connection with an adjacent front end of the second terminal groove so as to allow the base abutting portion 311 to be located below the flat abutting portion 321. Specifically, an arrangement of the first terminal groove 21 is configured for holding and fixing the first contact terminal 32. Similarly, an arrangement of the second terminal grooves 22 are configured for holding and fixing the second contact terminals 32. The design in which the front end of the first terminal groove 21 is in communication with the front end of the adjacent second terminal groove 22 can ensure that the base abutting portion 311 of the first contact terminal 31 protrudes below the flat abutting portion 321 of the second contact terminal 32. Therefore, the elastic or variable gap 33 is formed between the base abutting portion 311 and the flat abutting portion 321.

(20) In some embodiments, as shown in FIGS. 1 to 3, a periphery of the front end of the housing 10 is provided with a protruding curve edge 12 bent outward to facilitate insertion of the USB plug 40 into the cavity 11. Specifically, an arrangement of the protruding curve edge 12 can make the front end of the housing 11 to form an arc shape, so as to guide the USB plug 40 to be inserted into the cavity 11 of the housing 10. The protruding curve edge 12 has a guiding function to speed up the match between the USB plug 40 and the USB socket.

(21) In some embodiments, as shown in FIGS. 1 to 3, a periphery of the rear end of the housing 10 is provided with a bending edge 13 bent outward to enhance the connection stability between the housing 10 and an external component. Specifically, an arrangement of the bending edge 13 can strengthen a fastening force of the housing 10 fixed to an external component (such as an electronic device), so that the mounting of the entire USB socket is more stable and reliable.

(22) In some embodiments, as shown in FIGS. 1 to 3, first elastic pieces 14 bent toward the cavity 11 for abutting against the USB male socket 40 are formed on both a top portion and a bottom portion of the housing 11. Specifically, each of the first elastic pieces 14 is configured to press against a USB plug working surface inserted in the cavity 11, increase the friction between the USB socket and the USB plug 40, and further increase the stability and reliability of the insertion connection between the USB socket and USB plug 40.

(23) In some embodiment, as shown in FIGS. 1 to 3, second elastic pieces 15, which bend toward the cavity 11 for abutting against the USB male socket 40, are formed on both sides of the housing 10. Similarly, each of the second elastic pieces 15 is configured to press against a USB plug working surface inserted in the cavity 11, increase the friction between the USB socket and the USB plug 40, and further increase the stability and reliability of the insertion connection between the USB socket and USB plug 40.

(24) As shown in FIG. 9, an embodiment of the present application further provides a button controller including a controller body 50. The above USB socket according to one embodiment of the present invention is arranged on the controller body 50. Because the above USB socket is applied to the button controller of the embodiment of the present application, it be can ensured that the button controller achieves zero standby state when the USB socket is not plugged to the USB male socket, so as to avoid power consumption loss.

(25) An embodiment of the present application further provides a smart appliance including a furniture or appliance body. The button controller is arranged on the furniture or appliance body. Because the above button controller is applied to the smart appliance of the embodiment of the present application, so it can be ensured that the button controller achieve zero standby state when the USB socket of the button controller is not plugged to the USB plug, so as to avoid power consumption loss.

(26) The smart appliance of the embodiment of the present application can be a functional sofa or the like.
