Description

Technical Field

[0001] The present application relates to the technical field of electrical sockets, and in particular to a universal socket. Background Art

[0002] As the pace of globalization accelerates, the number of cross-border business trips has shown a significant growth trend. In this context, improving the convenience of cross-border business trips has become particularly important, which not only affects the personal travel experience, but is also an important factor in promoting global development.

[0003] In cross-border business trips, electronic communication products have almost become an indispensable companion. However, there are often significant differences in the power supply infrastructure between different countries, especially the specifications and safety requirements of electrical sockets. This difference has brought many inconveniences to the charging of electronic products during cross-border travel. In order to solve this problem, some multi-purpose conversion pin designs have appeared on the market, such as folding structures and telescopic pin structures with protective functions. Although the multi-purpose conversion sockets on the market currently provide sockets of various specifications, they often fail to fully consider the arrangement and layout between the sockets. This makes it possible for users to encounter interference between plugs when using them, reducing the convenience of use. In addition, unreasonable socket arrangement may also affect the heat dissipation effect of the socket, increasing safety hazards.

[0004] In summary, the existing cross-border travel charging solutions still have many shortcomings, and it is urgent to develop a more convenient, efficient and universal cross-border travel charging conversion equipment to meet the growing needs of cross-border travel. Utility Model Content

[0005] In view of the shortcomings of the prior art, a universal socket is proposed. The purpose of this application is to optimize the structure of the universal socket to solve the above problems.

[0006] The above-mentioned purpose of the present application is achieved through the following technical solutions: a universal socket, including a socket body, the socket body including a socket upper cover and a socket lower shell, the socket upper cover is provided with a plurality of jacks, the jacks include a first jack, a pair of second jacks and a pair of third jacks, the pair of the second jacks are symmetrically arranged, the pair of the third jacks are symmetrically arranged, a fourth jack is provided between the two holes of the second jack, a fifth jack is provided between the two holes of the third jack, and a pin assembly is provided at the lower end of the middle part of the socket lower shell.

[0007] By adopting the above technical solution, considering that the universal socket needs to have sockets for use with standard pins of different countries, by integrating the design of sockets of multiple different specifications in the same area, multiple sockets can be combined into sockets of different national standards. At the same time, the overall structure becomes more compact, thereby reducing the overall volume and improving the portability and user experience of the universal socket.

[0008] Furthermore, the first socket, the fourth socket and the fifth socket are connected and are all grounding sockets.

[0009] By adopting the above technical solution, the use of socket cover materials is reduced, the compactness of the overall structure is further improved, and the universal effect is enhanced.

[0010] Furthermore, the pin assembly includes retractable pins of various specifications, the retractable pins include a first pin, a second pin and a third pin, a plurality of pin retractable holes are provided at the bottom of the socket lower shell, the retractable pins are inserted into the pin retractable holes, the pin assembly also includes a plurality of push buttons, the push buttons include a first push button, a second push button and a third push button, the first push button is fixedly connected to the first pin, the second push button is fixedly connected to the second pin, the third push button is fixedly connected to the third pin, a plurality of open grooves are provided on the side wall of the socket lower shell, and a plurality of push buttons are slidably connected in the open grooves.

When using, only the push button corresponding to the specific pin needs to be selected to push the pin out, thus avoiding the trouble of selecting and classifying different pins, and improving the convenience of using the universal socket.

[0012] Furthermore, the socket upper cover is fixedly provided with a USB socket, and the USB socket is opened on a side away from the socket.

[0013] By adopting the above technical solution, considering that small household appliances such as mobile phones can be directly connected to the universal socket via a charging data cable, there is no need to use a dedicated pin to connect to the universal socket, thereby simplifying the portable equipment required for charging and improving the simplicity and convenience of using the socket.

[0014] Furthermore, the socket cover is also fixedly provided with a plurality of Type-C sockets.

[0015] By adopting the above technical solution, considering that the charging data cables of existing electronic devices are mostly Type-C cables, the versatility of the socket is improved by providing a Type-C socket. Since the universal socket can meet the charging needs of multiple small electronic devices at the same time, providing multiple Type-C sockets can increase the number of devices that the universal socket can carry at the same time and the efficiency of charging multiple devices.

[0016] Furthermore, the socket upper cover is provided with a plurality of positioning holes and plugging slots, and the socket lower shell is fixedly provided with positioning column feet matching the positioning holes and plugging flanges matching the plugging slots.

[0018] Furthermore, a plastic sealing protection pad is fixedly installed on the socket upper cover.

[0019] By adopting the above technical solution, considering that the general socket may work in a humid environment, a plastic sealing protection pad is provided to isolate the positioning holes and the plugging grooves from the surrounding environment, which can better protect the components in the socket body, reduce the probability of component rust and failure, and improve the service life of the overall device.

[0020] Furthermore, the socket body further includes a U-shaped support frame, the support frame is placed between the socket upper cover and the socket lower shell, and the upper end of the support frame is fixedly connected to the socket upper cover.

[0021] By adopting the above technical solution, since the general socket generates a large amount of heat during operation, a U-shaped support frame is provided to separate the jacks, the USB sockets and the Type-C sockets into two parts, avoiding the mutual interference of heat between the two parts and improving the overall heat dissipation effect.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. The general socket adopts an integrated design, combines jacks of various different specifications in the same area to form jacks of different national standards, reduces the volume, improves the portability, and brings a better user experience;

[0024] 2. The general socket is configured with retractable pins of various specifications, and the required pins can be pushed out through simple operations, avoiding the trouble of classification selection and greatly improving the use convenience;

[0025] 3. The general socket supports direct connection of charging data cables without special pins, simplifies the charging device, and improves the simplicity and convenience of use. At the same time, the socket adopts a plug-connected design, which is convenient for maintenance and replacement of parts. In addition, the setting of the support frame effectively separates the jacks and the USB sockets, improving the overall heat dissipation effect. BRIEF DESCRIPTION OF THE DRAWINGS
