DETAILED DESCRIPTION

[0033] The specific implementation of the socket with USB power supply of the utility model is further described below in conjunction with the embodiments given in the accompanying drawings. The socket with USB power supply of the utility model is not limited to the description of the following embodiments.

[0034] A wall socket is an electrical switch installed on the wall to connect the power supply to the electrical equipment. A wall socket generally includes: a base, a socket assembly and a cover plate. For the sake of aesthetics, further fixation, and protection, a panel cover is usually provided on the cover plate. The base is generally embedded in the slot of the wall, the socket assembly is generally arranged in the base, and the cover plate is provided with corresponding jacks corresponding to the socket assembly. Similarly, the panel is also provided with corresponding jacks. The socket with USB power supply is based on the existing wall socket, and a USB interface and its corresponding module are added to realize the power supply for small electrical appliances, mobile terminals and other equipment.

[0035] like Figure 1-2 As shown, this embodiment is a socket with a USB power supply, comprising: a base 10, a USB power supply component 20, a socket component 40, and a cover plate 60. Furthermore, a panel 70 can be arranged on the cover plate 60 for decoration, further fixing and sealing.

[0036] In this embodiment, Figure 2-3, the base 10 is provided with an inner chamber 11, and the inner chamber 11 is provided with a first partition 12 to divide it into a first inner chamber 13 and a second inner chamber 14; the USB power assembly 20 is provided in the second inner chamber 14 of the base 10, and the plug assembly 40 is provided in the first inner chamber 13, and the cover 60 is covered on the base 10 to seal the USB power assembly 20 and the plug assembly 40. The first partition 12 is provided with a partition notch, and the two electrical wires connecting the plug assembly 40 are connected to the USB power assembly 20 in the second inner chamber 14 through the partition notch.

[0037] In this embodiment, combined with Figure 2 , Figure 3 and Figure 7 As shown, the USB power supply assembly 20 includes a USB power board 21 and a USB interface 22 arranged on the USB power board 21. The USB power board 21 is inserted and arranged along the recessed direction of the second inner chamber 14. The interface setting direction of the USB interface 22 is opposite to the insertion direction of the USB power board 21. The cover plate 60 is provided with a USB avoidance hole 62 in the area corresponding to the USB power supply assembly to avoid the USB interface 22. The USB power board 21 is arranged in the second inner chamber 14 of the base 10, which can avoid the increase of the structural thickness of the exposed wall portion due to the addition of the USB power supply assembly 20. At the same time, the USB power board 21 is arranged in an inserted manner so that the board surface and the recessed direction of the second inner chamber 14 are consistent, thereby reducing the horizontal (i.e. width or length) space requirement of the base 10. In this way, the appearance of the exposed wall portion and the horizontal size of the socket of this embodiment are not affected, thereby ensuring its beauty and practicality.

[0038] In this embodiment, if Figure 2 and 3a As shown, both ends of the second inner chamber 14 are provided with slots 141 for inserting the USB power board 21. The USB power board 21 is limited by the slots 141. The structure is relatively simple. The USB power board 21 can be inserted into the slots 141 with a certain interference fit, thereby preventing the USB power board 21 from falling out of the base 10 before the cover 60 is closed.

[0039] Furthermore, the slot 141 is formed by extending upward from the bottom wall of the second inner chamber 14, and a connecting rib 142 is provided on the back of the slot 141 to connect to the side wall of the second inner chamber 14. Since the base 10 is generally a plastic part formed by a mold, and the inner chamber 11 generally has a certain depth, in order to smoothly demould without causing product defects, the cavity wall of the inner chamber 11 usually has a certain inclination to ensure smooth demoulding, and in order to effectively limit the USB power board 21, the slot 141 is parallel to the insertion direction of the USB power board 21, so it is formed by directly extending upward from the bottom wall, and in order to ensure its structural strength, it is connected to the side wall through the connecting rib 142, which can effectively improve its structural strength.

[0040] In this embodiment, if Figure 7 As shown, since the USB power board 21 is provided with a variety of components, such as a filter component 23, a transformer component 24, and an AC-DC conversion module, etc., these components will generate heat during use. Figure 3a and Figure 3b As shown, by providing a plurality of heat dissipation holes 143 on the wall of the second inner chamber 14 , the temperature inside the socket can be effectively reduced.

[0041] In this embodiment, a detachable strong and weak current isolation plate 25 is also provided on the USB power board 21 to isolate the USB interface from various conversion modules, such as the filter component 23, the transformer component 24 and the AC-DC conversion module, to ensure the safety of the USB interface. The strong and weak current isolation plate 25 can be detachably inserted into a horizontal jack (not shown) preset at the relay position of the circuit board, and can also be fixedly welded on the USB power board.

[0042] Furthermore, the plurality of heat dissipation holes 143 are long strip holes, and the arrangement direction thereof is to extend along the direction of the depression of the second inner chamber 14, and the width of the plurality of heat dissipation holes 143 gradually increases in the extension direction thereof. Since the upper portion of the heat dissipation holes 143 is mainly close to the main body of the base and is the main structural connection part (such as the connection with the upper convex edge and the connection structure with the USB power board), a smaller width is beneficial to ensure the structural strength of the second inner chamber 14, and since the lower portion is not used to carry any components, a larger width can be used to increase the overall opening area of ​​the heat dissipation holes 143, which is more conducive to internal heat dissipation.

[0043] Furthermore, the plurality of heat dissipation holes 143 are arranged in the lower area of ​​the side wall of the second inner chamber 14 adjacent to the bottom wall. The area adjacent to the bottom wall does not need to bear other components. Therefore, the heat dissipation holes 143 are arranged in the area adjacent to the bottom wall under no force, which can better ensure the structural strength of the base 10.

[0044] Further, combined with Figure 3a and Figure 7 As shown, a positioning boss 144 is provided on the bottom wall of the second inner chamber 14, and a positioning notch 214 corresponding to the positioning boss 144 is provided on the side of the USB power board 21 facing the bottom wall of the second inner chamber 14. When the USB power board 21 is inserted, the positioning notch 214 and the positioning boss 144 form mutual limitation, further ensuring the installation reliability of the USB power board 21.

[0045] In this embodiment, if Figure 4 and Figure 5 As shown, the socket assembly 40 includes a socket 41, a socket pressure plate 42, a protective door 43 and a wiring terminal 44. The socket 41 includes a three-pin socket 411, a two-pin socket 412 and a terminal connection portion 413. The three-pin socket 411 includes a ground wire, a live wire and a neutral wire socket, and the two-pin socket 412 includes a live wire and a neutral wire socket. The ground wire and live wire sockets of the three-pin socket 411 and the live wire and neutral wire sockets of the two-pin socket 412 are integrally formed with copper sheets. The terminal connection portion 413 is arranged below the three-pin socket 411 and the two-pin socket 412 and is integrally formed with the corresponding copper sheet. Figure 3a As shown, the three-plug socket 411 and the two-plug socket 412 are respectively arranged in the first socket setting area 131 and the second socket setting area 132 at both ends of the first inner chamber 13, and the first socket setting area 131 and the second socket setting area 132 are provided with multiple limiting structures to limit the socket 41.

[0046] The area between the first socket setting area 131 and the second socket setting area 132 is provided with a terminal setting groove 135 extending downward, the wiring terminal 44 is provided in the terminal setting groove 135, and the terminal connecting portion 413 extends to the terminal setting groove 135 and is connected to the wiring terminal 44. The wiring terminal is provided between the three-pin socket 411 and the two-pin socket 412, which is conducive to increasing the distance between the two sockets and facilitating simultaneous use. Different from some methods of providing the wiring terminal on the side, the downward arrangement can reduce the demand for lateral space and maintain the basic lateral (length or width) size of the base 10.

[0047] In this embodiment, a second partition 136 is further provided between the second socket setting area 132 and the terminal setting groove 135 for isolating the two-pin socket 412 from the wiring terminal 44 to prevent the live wire socket and the neutral wire socket of the two-pin socket 412 from contacting the ground terminal.

[0048] In this embodiment, Figure 6As shown, the area of ​​the cover plate 60 corresponding to the socket assembly 40 is provided with a limiting structure (not shown in the figure) for limiting the protective door, and the area corresponding to the socket 41 of the socket assembly 40 is provided with a jack. In this embodiment, the jack includes a three-pin jack corresponding to the three-pin socket 411 and a jack corresponding to the two-pin socket 412. The area of ​​the cover plate 60 corresponding to the USB power supply assembly 20 is provided with a USB avoidance hole 62 for avoiding the USB interface 22.

[0049] The edge of the cover plate 60 is provided with a first protrusion 65, and the first protrusion 65 is provided with a first buckling structure 651 in the direction toward the base 10. Figure 3a As shown, a second protrusion 15 is also provided at the edge of the base 10, and a sinking groove 16 adapted to the shape of the cover plate 60 is provided in the area of ​​the second protrusion 15 corresponding to the cover plate 60, and the cover plate 60 is covered in the sinking groove 16, and a first snap-fit ​​structure 161 corresponding to the first snap-fit ​​structure 651 is provided in the edge area of ​​the sinking groove 16. The cover plate 60 is fixed by the first snap-fit ​​structure 651 in cooperation with the first snap-fit ​​structure 161 to form a limited fixation, and the snap-fit ​​fixation method makes the installation of the cover plate 60 more convenient and more efficient.

[0050] Further, such as Figure 1 , Figure 2 and Figure 8 As shown, in order to further improve the reliability of the socket, a panel 70 is further provided on the cover plate 60 , a second buckling structure 702 is provided on the inner side of the side wall of the panel 70 , and a corresponding second locking structure 102 is provided on the outer edge of the base 10 .

In addition, the terms "first", "second", "third", etc. are only used to distinguish descriptions, and cannot be understood as indicating relative importance.

[0052] The above contents are further detailed descriptions of the present invention in combination with specific preferred implementations, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the protection scope of the present invention.
