[0001] This utility model relates to the field of aviation power sockets, and more particularly to an aviation power socket with a three-hole socket and a TYPE-C interface. Background Technology

[0002] With the increasing variety of travel options available to people, and the growing number of people choosing to travel by air, the demand for charging electronic devices during flights is also becoming more diverse. Therefore, to meet these diverse charging needs, airline seats are often equipped with charging sockets for electronic devices.

[0003] AC (Alternating Current) refers to alternating current, while DC (Direct Current) refers to direct current.

[0004] In the prior art, Chinese utility model publication number CN220421062U discloses a seat power output socket with USB. By setting up a USB interface and a three-hole socket for use, it is convenient for passengers to charge USB devices. It can also charge devices powered by AC. However, with the rapid development of electronic devices, the initial USB standard was designed mainly for data transmission. Therefore, its standard output voltage is 5V and the maximum current is usually 500mA or 900mA, which limits its charging speed. Therefore, the output power of the USB interface can no longer meet the charging needs of existing high-power products. Therefore, it is urgent to design a solution to solve the above problems. Utility Model Content

[0005] To address the problem that the output power of the USB interface in the aforementioned technologies is too low to meet the charging needs of existing high-power products, this utility model provides an aviation power socket with a three-hole socket and a TYPE-C interface. The socket includes a housing containing two independent first cavities and a second cavity.

[0022] To more clearly illustrate this utility model, the following description, in conjunction with the accompanying drawings, will provide a further picture.

[0023] In the following description, specific examples of general selection are given to provide a more in-depth understanding of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of them. It should be understood that the specific embodiments described are only used to explain the present invention and are not intended to limit the present invention.

[0024] It should be understood that when the terms “comprising” and / or “including” are used in this specification, they indicate the presence of a feature, whole, step, operation, element, or component, but do not exclude the presence or addition of one or more other features, wholes, steps, operations, elements, components, or combinations thereof.

[0025] Please see Figures 1 to 4The present invention relates to an aviation power socket with a three-hole socket and a TYPE-C interface, comprising a housing 1, wherein the housing 1 is provided with two independent first cavities 2 and second cavities 3. The first cavity 2 is equipped with a first circuit board 4, which is provided with a TYPE-C interface 6 and a DC input wire 8 electrically connected thereto. The second cavity 3 is equipped with a second circuit board 5, which is equipped with a three-hole socket 7 and an AC input wire 9 electrically connected thereto. The aviation power socket is connected to the power source via DC input wire 8 and AC input wire 9. DC power is input through DC input wire 8, filtered by a protection device to smooth the voltage, and then input to the first circuit board 4. The first circuit board 4 is equipped with a DC-DC converter, which converts the filtered DC power into the required stable DC voltage, which is then output through a Type-C interface. AC power is input through AC input wire 9, and after passing through a protection mechanism, is input to the second circuit board 5. The second circuit board includes an AC terminal module, which outputs AC power through a three-hole socket 7, allowing other devices to obtain power through this socket. The output voltage is related to the upstream power supply equipment. More specifically, during the DC power output process, 28V DC power is input to the first circuit board 4 through DC input wire 8. The transformer module of the first circuit board 4 then adjusts the voltage, automatically identifying the power of the receiving device through a Type-C chip, and finally adjusting the output current and voltage (5V3A, 9V3A, 12V3A, 20V3A) to achieve the function of fast charging the receiving device.

[0026] Please see Figure 2 The system also includes a housing cover plate 10, which is fixed to the housing 1 by fasteners. The housing cover plate 10 is also provided with through holes corresponding to the TYPE-C interface 6 and the three-hole socket 7, allowing the TYPE-C 6 and the three-hole socket 7 inside the housing 1 to be exposed to the outside of the housing 1. The housing cover plate 10 forms a detachable connection with the housing 1, which facilitates the replacement and maintenance of the internal components of the housing 1. At the same time, the housing cover plate 10 and the housing 1 form a certain sealed space to prevent the circuit board from getting damp and to prevent dust from causing short circuits on the circuit board.

[0027] Please see Figure 2 and Figure 5The housing 1 has inwardly recessed mounting grooves 11 on both sides. Each mounting groove 11 has a threaded vertical rod 12. A nut 13 is installed at one end of the threaded vertical rod 12, and a bearing 14 is installed at the other end. The nut 13 passes through the top of the mounting groove 11 and is exposed to the outside. The bearing 14 is installed on the bottom surface of the mounting groove 11. A pressure plate 15 and a spring 16 are also provided within the mounting groove 11. The pressure plate 15 has a threaded through hole through which the threaded vertical rod 12 is rotatably fitted. The spring 16 is also fitted onto the threaded vertical rod 12, with one end abutting against the pressure plate 15 and the other end abutting against the bottom surface of the mounting groove 11. By providing the pressure plate 15 within the mounting groove 11, the housing 1 and the pressure plate 15 cooperate to engage with an external object, thus securing the socket to the object. More specifically, the pressure plate 15 is configured with an L-shaped structure and has an abutment end and a connecting end. A threaded through hole is provided at the connecting end, and the abutment end forms an interlocking structure with the housing 1 to fix the external object. When fixing the socket, the nut 13 of the threaded vertical rod 12 is rotated using a tool, causing the threaded vertical rod 12 to rotate. Since the connecting part of the pressure plate 15 is provided with a threaded through hole, the pressure plate 15 moves linearly along the threaded vertical rod 12 toward the housing cover plate 10. The pressure plate 15 moves continuously until it abuts against the external object, and finally fixes the external object between the abutment part of the pressure plate 15 and the housing 1. When disassembling the socket, the nut 13 of the threaded vertical rod 12 is rotated in the opposite direction of reinforcement, causing the pressure plate 15 to gradually move away from the external object. When the clamping force between the pressure plate 15 and the housing 1 is insufficient, the socket can be removed from the external object. After the socket is removed, the pressure plate 15 can also be screwed into the mounting groove 11 for storage.

[0028] Please see Figure 2 and Figure 3 It also includes an indicator light 17, which is installed inside the housing 1 and electrically connected to the second circuit board 5. The light-emitting part of the indicator light 17 extends from inside the housing 1 through the housing cover 10 and is exposed outside the housing 1. The indicator light 17 is exposed outside the housing 1 through the housing cover 10 and is on the same plane as the TYPE-C interface 6 and the three-hole socket 7. Therefore, the indicator light 17 is easily noticeable when the device is charging, so that people can know the operating status of the socket in real time.

[0029] Please see Figure 3 and Figure 4 The housing is provided with a wire through hole 18, which allows the DC input wire 8 and the AC input wire 9 to extend from inside the housing 1 to the outside of the housing 1. The fact that the DC input wire 8 and the AC input wire 9 are located outside the housing 1 allows for more flexible installation of the socket, as the DC input wire 8 and the AC input wire 9 extend the connection distance between the socket and the power source.

[0030] Please see Figure 4Both the DC input cable 8 and the AC input cable 9 have locking clips 19 at their connectors, which ensure a secure connection between the DC input cable 8 and the AC input cable 9 and the power supply. The locking clips 19 at the connectors of the DC input cable 8 and the AC input cable 9 provide a more stable connection to the power supply, as aircraft experience frequent minor turbulence during flight; therefore, the locking clips 19 prevent the input cables from becoming detached from the power supply.

[0031] The advantages of this utility model are:

[0032] 1. This utility model is equipped with a three-hole socket and a TYPE-C interface, which can provide passengers with DC and AC power to adapt to various electronic devices of passengers.

[0033] 2. The TYPE-C interface of this utility model is electrically connected to a first circuit board. The chip built into the first circuit board can automatically identify the power of the powered device and thus output appropriate power to achieve the fast charging function.

[0034] The above-disclosed embodiments are only a few specific examples of this utility model. However, this utility model is not limited thereto. Any variations that can be conceived by those skilled in the art should fall within the protection scope of this utility model.
