TECHNICAL FIELD

[0001] The utility model relates to the field of power socket, especially a wall socket with USB charging port. BACKGROUND

[0002] With the popularization of consumer electronics products and the increase of its categories, the wall socket with USB charging port has been widely used in public places and family residences because it is convenient to charge mobile phones, tablets and other electronic products without using power adapters. The wall socket with USB charging port is mainly composed of a strong current functional part, a USB functional part and a shell, wherein the shell includes a base, an inner panel and an outer panel. When designing the wall socket with USB charging port, although the strong current functional part and the USB functional part have been standardized, due to the diversification of product positioning, there are different series of products such as conventional and ultra-thin products. In order to ensure reliable contact between the plug and the USB interface and meet the uniqueness of the appearance of different series of products, the shell needs to be designed separately for different series of products, which leads to excessive repetitive design of the shell, low research and development efficiency, and the need to open a mold for each series of products to make the shell, which greatly increases the production cost. SUMMARY

[0003] In order to solve the above technical problems of low product universality and high production cost, the utility model provides a wall socket with USB charging port, which improves the standardization degree of the product, increases the universality of the product, and reduces the production cost.

[0004] The specific technical scheme of the utility model is as follows: a wall socket with USB charging port, including base, strong current functional part, USB functional part, inner panel and outer panel, strong current functional part, USB functional part and inner panel are installed on the base, and the inner panel shields the USB functional part, the outer panel is connected with the inner panel or the base and shields the inner panel, the USB functional part is provided with a USB interface, the inner panel is provided with a through hole corresponding to the position of the USB interface, the outer panel is provided with a USB charging jack hole corresponding to the position of the USB interface, the USB interface passes through the through hole and extends out of the front surface of the inner panel, and the end face of the USB interface away from the base is located in the USB charging jack hole.

[0005] After the socket is assembled, the end face of the USB interface away from the base is located in the USB charging socket and protrudes from the front surface of the inner panel by a certain distance, thereby increasing the insertion allowance of the USB interface, ensuring reliable contact between the USB plug and the USB interface, expanding the gap range that can be designed between the outer panel and the inner panel, and allowing the product height to be flexibly adjusted without exceeding the maximum gap. Thus, the base and the inner panel can be used as standard parts, and only a few sets of standard parts can be combined to cover all series of products, thereby improving the standardization of the products, improving the production efficiency, reducing the production cost, providing strong support for the serialization expansion and adaptation to diversified installation environments of the products, and improving the universality and reliability of the products. In the wall socket with a USB charging port, the product height refers to the vertical distance from the wall to the outer surface of the outer panel.

[0006] Preferably, a gap is provided between the front surface of the inner panel and the back surface of the outer panel.

[0009] In the above technical solution, the first support is provided to enhance the structural stability of the socket during the insertion of the USB plug, prevent the outer panel from being deformed due to external force, and guide the insertion and removal of the USB plug, thereby facilitating the insertion and removal of the USB plug. In addition, the first support reinforces the structure of the USB charging socket, so that the USB charging socket is not prone to edge warping.

[0010] Preferably, the first support is arranged around the corresponding USB charging socket to form a ring structure.

[0011] In the above technical solution, the first support has a ring structure, which can uniformly disperse the external force received by the outer panel, avoid the phenomenon of local stress concentration, and further enhance the stability of the overall structure of the socket. In addition, the ring structure has a full-range guiding effect, so that the user does not need to align a certain point when inserting and removing the socket, thereby improving the insertion and removal efficiency of the USB plug.

[0012] Preferably, a strong current socket is provided on the outer panel, and the edge position of the strong current socket is inwardly protruded to form a second support.

[0013] In the above technical solution, the second support is provided to enhance the structural stability of the socket during the insertion of the multi-hole plug, and prevent the outer panel from being deformed due to external force.

[0014] Preferably, the distance between the end face of the USB interface away from the base and the front face of the outer panel is a, and the gap width between the front face of the inner panel and the back face of the outer panel is b, a≥b.

[0015] In the above technical solution, the port of the USB interface is located between the front face and the back face of the outer panel, and the USB plug is more easily connected with the USB interface, so that the plug is more convenient to plug and unplug.

[0016] Preferably, the gap width is 0.5mm-3mm.

[0017] Preferably, the inner panel and the base are detachably connected through a buckle structure, and the outer panel and the base are detachably connected through a buckle structure.

[0018] In the above technical solution, the inner panel and the outer panel are connected with the base respectively, so that the appropriate inner panel or outer panel can be quickly switched according to actual needs, and the product diversification and customization are realized.

[0019] Preferably, a plurality of through holes are arranged on the inner panel, the number of the USB interfaces is equal to the number of the USB charging jack, and the number of the USB charging jack on the outer panel is less than or equal to the number of the through holes on the inner panel.

[0020] In the above technical solution, since the number of the USB interfaces and the number of the corresponding USB charging jack are different for different product series, the inner panel with more through holes can better compatible different product series, and the versatility of the inner panel is improved.

[0021] Compared with the prior art, the utility model has the following advantages:

[0022] (1) high degree of standardization, high production efficiency: by increasing the insertion amount of the USB interface, the gap range between the outer panel and the inner panel can be designed to expand while ensuring reliable contact between the plug and the interface, so that the product height can be flexibly adjusted within the range of the maximum gap, without the need to adjust the base and the inner panel, so that reliable contact between the plug and the interface of different height product series can be realized, so that the base and the inner panel can be used as standard parts, and only a few standard parts can cover all series of products, thereby improving the degree of standardization of the product and improving the production efficiency.

[0023] (2) low cost: the base and the inner panel can be used as standard parts, and can be compatible with different product series, without the need to open a mold for each product series to manufacture the base and the inner panel mold, thereby reducing the production cost.
