[0019] A charging plug mounting hole is provided on the front panel 10. There are three charging plug mounting holes, which are arranged in a triangular shape. Two of the charging plug mounting holes are symmetrically distributed and there are two types. The grounding charging plug mounting hole includes adjacent rectangular holes and arched holes, which are arranged in a straight line to correspond to different plugs. The two charging plug mounting holes connecting the live wire and the neutral wire are arranged as T-shaped holes. A stepped concave-convex structure is provided on the top surface of the T-shaped hole to accommodate the access of different plugs. The stepped concave-convex structure is six continuous sections of wedge-shaped surfaces with a 30-degree angle. The wedge-shaped surface can achieve a guiding effect when different plugs are connected, and can match a variety of connector models with the T-shaped hole setting, effectively improving the docking installation efficiency and applicability.

[0020] The rear cover is provided with three circuit board fixing bolt seats, and the first circuit board fixing bolt seat is installed on the upper end surface of the left side of the rear cover; a light guide column 11 is installed in the main shell 9, and a hollow area adapted to the light guide column 11 is provided on the front panel 10.

[0021] The rear cover 1 is provided with a nameplate 14 and an SN label 15 on the outside.

[0022] The cable assembly 2 includes a connector shell, which includes an upper connector shell 21 and a lower connector shell 23. The upper connector shell 21 and the lower connector shell 23 are butt-jointed and installed. A crimping terminal 22 is installed in the upper connector shell 21. A multi-core shielded wire 27 is connected to the crimping terminal 22. A heat shrink tube 25 is sleeved between the connector shell and the multi-core shielded wire 27. The multi-core shielded wire 27 is externally coated with a braided sleeve 26, which is fixed by a cable tie 24. The multi-core shielded wire 27 is connected to a micro switch reed 28. The crimping terminal is a Micro-Fit 3.0 crimping terminal.

[0023] The main circuit board assembly 6 includes a main circuit board 41, on which are respectively provided an LED lamp column 1 42, a chip resistor 1 44, a PogoPin connector 46, and a USB board internal threaded column 47; a micro switch reed 2 45, a chip resistor 2 48, and an LED lamp column 2 49 are installed at the bottom of the main circuit board 41; there are two micro switch reeds 2 45, namely a first micro switch reed 2 and a second micro switch reed 2.

[0024] The electrode socket assembly 13 includes a safety buckle 31 , a cylindrical compression spring 32 , and an electrode socket 33 . The electrode socket 33 is movably inserted into the safety buckle 31 , and a cylindrical compression spring 32 is provided between the electrode socket 33 and the safety buckle 31 .

[0025] There are three electrode sockets 33, each of which has a corresponding safety buckle 31 installed inside, and the three electrode sockets 33 are arranged in a triangle, wherein the first electrode socket 33 is connected to the ground wire, the second electrode socket 33 is connected to the neutral wire, and the third electrode socket 33 is connected to the live wire; The safety buckle 31 is a T-shaped structure, with a crimping joint at the bottom of the T-shaped structure and a groove matching the charging plug at the top of the T-shaped structure; the electrode socket 33 includes an electrode docking port, which is a convex structure with an open upper end, the convex structure is hollow inside, and the upper surface of the convex structure also has a dividing groove, which can effectively match different plug structures by setting the dividing groove. A safety buckle docking plate and a cylindrical compression spring mounting plate are installed on one side of the electrode docking port, and a through hole is provided at the bottom of the electrode socket 33 to allow the crimping joint of the safety buckle 31 to pass through; The crimping joint of the safety buckle 31 corresponding to the first electrode socket 33 passes through the electrode socket and contacts the micro switch reed 1 28, and drives the micro switch reed 1 28 to be pressed down to the access state; the crimping joint of the safety buckle 31 corresponding to the second electrode socket 33 passes through the electrode socket and contacts the first micro switch reed 2, and drives the first micro switch reed 2 to be pressed down to the access state; the crimping joint of the safety buckle 31 corresponding to the second electrode socket 33 passes through the electrode socket and contacts the second micro switch reed 2, and drives the second micro switch reed 2 to be pressed down to the access state; only when the micro switch reed 1 28, the first micro switch reed 2 and the second micro switch reed 2 are all in the access state, the circuit is conductive and charging can be carried out. When the three ports of the charging plug are inserted into the deepest part of the electrode socket 33, the metal sheet at the front of the charging plug presses down the metal spring inside the socket so that the metal spring contacts the circuit board contact. At this time, the electric shock protection of the entire circuit fails, and the main circuit enters the working state, which can effectively prevent electric shock caused by improper operations such as inserting foreign objects and accidental touch.

[0026] The rear cover 1 is provided with a circuit board fixing bolt seat 101 and a bolt hole 102 , a wiring hole 103 is provided on one side of the rear cover 1 , and a tie through hole 104 is provided on the rear shell 1 .

[0027] A plurality of electrode cavities 90 are disposed in the main housing 9 , and a light guide column cavity 91 is disposed in the main housing 9 .

[0028] The universal socket with arc protection device uses specially designed anti-spark and anti-electric shock components to effectively prevent electric shock caused by accidental touch, poor contact and other problems.

[0029] This product is redesigned with reference to the specifications of four sockets: Chinese, American, British, and European. It not only allows passengers to charge their electronic devices conveniently without having to carry extra socket converters, but also has a higher charging efficiency, making it convenient for passengers to charge quickly. Adapting to the aircraft's 110V power supply, it not only supports charging of medium-sized electrical appliances, but also has higher charging efficiency; The socket is equipped with an LCD signal indicator to help passengers identify the socket usage status; The socket shell is made of flame-retardant PC, which can effectively avoid problems such as overheating and burning; A thermistor is welded to the circuit board inside the socket to prevent the circuit from overheating, overloading, and other problems that may affect aircraft safety, thereby improving safety.

[0030] Install the socket according to CMM25-26-18 or the corresponding manual of the corresponding seat. First, insert the socket cable plug into the socket, test the seat according to the manual, check whether the electrical accessories of the seat are working properly, and record the status of the socket power indicator. Use a digital multimeter to measure the voltage between the electrode socket and the ground socket. After confirmation, the socket is considered to be in a usable state. When in use, passengers only need to insert the charging plug they carry with them into the deepest part of the socket to charge the charging device. When the charging plug is inserted to the deepest part, the metal sheet at the front of the plug presses the metal reed inside the socket down so that the metal reed contacts the circuit board contact. At this time, the electric shock protection of the entire circuit fails and the main circuit enters the working state. If the passenger does not insert the plug to the deepest part or a foreign object is inserted into the single hole, the two micro switch reeds will not be fully pressed down to contact the circuit board. At this time, the electric shock protection circuit is not closed and the socket will not supply power, which can effectively prevent electric shock caused by improper operations such as inserting foreign objects and accidental touch.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
