[0048] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0049] Please refer to Figure 1 - Fig.12 An embodiment of the utility model provides a USB aviation entertainment system connector socket 100 , and the socket 100 includes: a USB terminal 10 , an upper shell 20 , a lower shell 30 , a first circuit board 40 , a second circuit board 51 and a third circuit board 52 .

[0050] The USB terminal 10 extends into the upper shell 20 along the first direction F1. The lower shell 30 is snap-fitted with the upper shell 20, and an electrode window 31 is formed through the lower shell 20 along the first direction F1. The first circuit board 40 is placed flat in the lower shell 30, and a conductive layer 41 is formed on the side facing away from the upper shell 20, and the conductive layer 41 is electrically connected to external components through the electrode window 31. The second circuit board 51 and the third circuit board 52 are parallel to each other and are vertically placed on the first circuit board 40 and electrically connected thereto. The USB terminal 10 is arranged on the side of the first circuit board 40 close to the upper shell 20, and is located between the second circuit board 51 and the third circuit board 52, and is electrically connected to both or one of them.

[0051] Among them, the USB terminal 10 is designed to extend into the upper shell 20 along the first direction F1 to facilitate the connection between the connector and external devices (such as entertainment systems, electronic products). This position design is not only easy for passengers to plug and unplug USB devices, but also makes the layout of the connector more flexible in a limited space. The lower shell 30 is connected to the upper shell 20 and penetrates along the first direction F1 to form an electrode window 31, which ensures the electrical connection between the internal circuit board and the external components. This design ensures the stability of electrical signal transmission and provides a reliable channel for the access of the connector to the internal electrical network of the aircraft. A conductive layer 41 is formed on the side of the first circuit board 40 away from the upper shell 20, and is electrically connected to the external components through the electrode window 31. Such a layout of the conductive layer 41 ensures a good electrical connection and protects the circuit board from interference from the external environment. The parallel and vertical layout of the second circuit board 51 and the third circuit board 52 makes the most effective use of the internal space. The USB terminal 10 is arranged on the side of the first circuit board 40 close to the upper shell 20 and is located between the second circuit board 51 and the third circuit board 52, which effectively reduces the overall volume of the connector and improves the space utilization efficiency. The electrical connection method of the first, second and third circuit boards 52 enables the connector to better adapt to the access requirements of various electronic devices, while optimizing the overall circuit layout and improving the performance and stability of the connector.

[0052] More preferably, the upper shell 20 is snap-connected with the lower shell 30 along the first direction F1 and forms an accommodation space 60 inside, the USB terminal 10 and the first circuit board 40 are located in the accommodation space 60, and the first circuit board 40 is in contact with a side of the lower shell 30 where the electrode window 31 is formed.

[0053] Among them, the upper shell 20 and the lower shell 30 are snap-fitted along the first direction F1, so that the two shells can be tightly combined. This design simplifies the assembly process, while ensuring that the structure of the connector is firm and improving the overall stability. An accommodating space 60 is formed inside the connector, which is conducive to accommodating the USB terminal 10 and the first circuit board 40. Such a design takes into account the overall size and space utilization of the connector, so that the connector can be laid out more compactly under limited space conditions. The first circuit board 40 is fitted with a side of the lower shell 30 where the electrode window 31 is formed, ensuring a good connection between the electrode window 31 and external components. This tight combination not only contributes to the stable transmission of electrical signals, but also improves the overall electrical performance of the connector. The layout of the USB terminal 10 and the circuit board in the accommodating space 60 makes the connector easier to connect and maintain. When passengers need to connect or disconnect devices during a flight, this design can provide a more convenient user experience.

[0054] More preferably, the second circuit board 51 and the third circuit board 52 are located in the accommodation space 60, and the second circuit board 51 and the third circuit board 52 vertically disposed on the first circuit board 40 divide the accommodation space 60 into a first domain 61, a second domain 62 and a third domain 63 arranged side by side. The second domain 62 is located between the first domain 61 and the second domain 62, the USB terminal 10 is located in the second domain 62, and the electronic component 200 is arranged in the first domain 61 and the third domain 63, and is located on a side of the second circuit board 51 away from the third circuit board 52 and a side of the third circuit board 52 away from the second circuit board 51.

[0055] Among them, the vertical layout of the second circuit board 51 and the third circuit board 52, and their parallel relationship with the first circuit board 40, divide the accommodating space 60 into three side-by-side domains, namely the first domain 61, the second domain 62 and the third domain 63. Such a division fully takes into account the effective use of the internal space. In this division, the USB terminal 10 is located in the second domain 62, so that the USB connector is spatially independent. This helps to optimize the layout of the USB interface and make it easier for passengers to access and use it. The electronic components 200 are arranged in the first domain 61 and the third domain 63 to avoid interference with the USB terminal 10. At the same time, this orderly configuration helps to improve the stability and reliability of the overall circuit. The position of the USB terminal 10 and the configuration of the electronic component 200 take into account the use needs of the end user. Through reasonable internal space division, the designer makes the connector more in line with the user's actual operating habits when in use, improving the user experience.

[0056] More preferably, the upper shell 20 includes: a first main body 21 and a cover portion 22 .

[0057] The first body 21 and the lower shell 30 form an accommodating space 60 inside.

The socket 100 is combined with the external package 300, one side of the external package 300 is in contact with the first step 23, and the other side is flush with the side of the cover plate portion 22 away from the lower shell 30, and the components below the cover plate of the socket 100 are hidden by the external package 300.

[0058] Among them, the first body 21 and the interior of the lower shell 30 form a accommodating space 60, which provides appropriate placement space for the internal electronic components 200 and the connecting wires, which is conducive to the assembly and wiring of the overall structure. The cover plate portion 22 is formed on the side of the first body 21 away from the lower shell 30, and the external package 300 is combined with the socket 100, wherein one side of the external package 300 is in contact with the first step 23 to achieve a sense of unity in appearance. The other side is flush with the side of the cover plate portion 22 away from the lower shell 30, and the components below the cover plate of the socket 100 are effectively hidden by the external package 300, thereby improving the overall safety of the connector. Through this structural design, the internal components of the connector, especially the parts related to the electrical connection, are cleverly hidden under the external package 300 and the cover plate portion 22. This not only helps to improve the overall aesthetics of the connector, but also reduces the impact of the external environment on the internal components, thereby enhancing the stability of the connector.

[0059] More preferably, the upper shell 20 further includes: a screw hole column 24 , a guide rod and a locking member 26 .

[0060] Among them, a pair of screw hole columns 24 are symmetrically formed on the periphery of the first main body 21 and fixed to the external package 300 by screws 400. A guide groove 25 is formed on the periphery of the first main body 21 and connected to one of the pair of screw hole columns 24. The screw hole column 24 connected to the guide groove 25 is recorded as the first screw hole column 241, and the other screw hole column 24 is recorded as the second screw hole column 242. The locking member 26 is inserted into the guide groove 25 along the first direction F1 and penetrates to the lower shell 30, and a third screw hole column 243 corresponding to the first screw hole column 241 is formed on the locking member 26. The screw 400 passes through the third screw hole column 243 and the first screw hole column 241 in sequence and is fixed to the external package 300.

[0061] Among them, a pair of screw hole columns 24 are symmetrically formed on the periphery of the first body 21. This design helps to keep the connector balanced and stable when fixed. Through the pair of screw hole columns 24, the connector can be firmly fixed to the external package 300 by screws 400. The guide groove 25 is formed on the periphery of the first body 21 and is connected to one of the pair of screw hole columns 24. The function of the guide groove 25 is to guide and position the insertion direction of the locking member 26, ensure that the locking member 26 is inserted along the correct path when inserted, and help improve the accuracy and efficiency of assembly. The locking member 26 is inserted into the guide groove 25 along the first direction F1, and a third screw hole column 243 corresponding to the first screw hole column 241 is formed on the locking member 26. This design enables the locking member 26 to be inserted into the guide groove 25 in a specific direction, and through the cooperation with the first screw hole column 241 and the third screw hole column 243, the locking and fixing of the connector is achieved. The screw 400 passes through the third screw hole column 243 and the first screw hole column 241 in sequence and is fixed to the external package 300. This connection method completed by the screw 400 can ensure the firmness of the connector, so that it is not easy to loosen or fall off during use.

[0062] More preferably, the upper shell 20 further includes: a first latch 271 , a second latch 272 and a third latch 273 .

[0063] The first latch 271, the second latch 272 and the third latch 273 are respectively extended along the first direction F1 and are engaged with the lower housing 30, and are respectively formed on the periphery of the first body 21. When viewed along the first direction F1, the first latch 271 and the second latch 272 are respectively located on two sides facing the first body 21, and the third latch 273 is located on a side facing the guide groove 25.

[0064] Among them, the first latch 271, the second latch 272 and the third latch 273 are respectively extended along the first direction F1. This design enables the latch to extend in a specific direction and play a role of clamping. The first latch 271 and the second latch 272 are respectively located on the two sides facing the first body 21, and the third latch 273 is located on the side facing the guide groove 25. This distribution method helps to achieve correct alignment and clamping during insertion, ensuring that the connector can accurately enter the corresponding slot when plugged in. The clamping formed by the latch and the lower shell 30 not only plays a positioning role, but also can provide a certain resistance during clamping, thereby increasing the firmness of the connector.

[0065] More preferably, the lower housing 30 includes: a second body 32 , a first slot 331 , a second slot 332 and a third slot 333 .

[0066] The second body 32 and the first body 21 form an accommodation space 60 inside. Any direction perpendicular to the first direction F1 is recorded as the second direction F2. The first slot 331, the second slot 332 and the third slot 333 are respectively formed on the periphery of the second body 32 and penetrate the second body 32 along the second direction F2. When viewed along the first direction F1, the position of the first slot 331 corresponds to the first latch 271, the position of the second slot 332 corresponds to the second latch 272, and the position of the third slot 333 corresponds to the third latch 273, so as to form a snap connection between the upper shell 20 and the lower shell 30.

[0067] Among them, an accommodating space 60 is formed between the second body 32 and the first body 21, and the structure of the upper shell 20 is more stable through the slot that penetrates along the second direction F2. This helps the connector to withstand external shocks and vibrations during use and improves the overall durability. The first latch 271, the second latch 272 and the third latch 273 are respectively located at the periphery of the first body 21, and the corresponding slots penetrate the second body 32 along the second direction F2. This design ensures the accuracy and firmness of the clamping and avoids the situation that the connector becomes loose or falls off during use. The position of the slot corresponds to the latch, forming a multi-directional clamping structure. Such a design enables the connector to obtain stable clamping in multiple directions and is not easily affected by external interference or vibration. Observed along the first direction F1, the relative position of the slot and the latch ensures the correct clamping direction, so that the upper shell 20 and the lower shell 30 can be clamped together in the correct direction, ensuring the normal use of the connector.

[0068] More preferably, the electrode window 31 passes through the bottom surface of the second body 32 along the first direction F1, and the side of the first circuit board 40 formed with the conductive layer 41 is in contact with the inner bottom surface of the second body 32.

[0069] Among them, the electrode window 31 passes through the bottom surface of the second body 32 along the first direction F1, providing a channel for the connector so that the conductive layer 41 can be electrically connected to external components through the electrode window 31. This design ensures that the connector has a reliable channel when connecting electrical signals. The side of the first circuit board 40 formed with the conductive layer 41 is in contact with the inner bottom surface of the second body 32. Through this tight combination, the conductive layer 41 can effectively transmit electrical signals, reduce resistance, and improve conductivity. Observing along the first direction F1, the projection of the first circuit board 40 on the inner bottom surface of the second body 32 overlaps with the electrode window 31, indicating that the conductive layer 41 has a larger contact area within the range of the electrode window 31. This helps to improve the stability and reliability of the electrical connection.

[0070] More preferably, the first body 21 and the second body 32 are integrally formed by plastic injection molding.

[0071] This specific embodiment also provides a connector, including the USB aviation entertainment system connector socket 100 .

[0072] In this way, the assembly is completed by snapping the upper shell 20 and the lower shell 30 together, which is convenient for assembly. An electrode window 31 is formed through the lower shell 30, and a conductive layer 41 is formed on one side of the first circuit board 40, and is electrically connected to external components through the electrode window 31, so as to facilitate access to the internal electrical network of the aircraft; the USB terminal 10 is arranged between the second circuit board 51 and the third circuit board 52, which are parallel to each other and vertically arranged on the first circuit board 40, and is electrically connected to both or one of them, so as to optimize the internal space layout of the connector socket 100 in combination with the shape characteristics of the USB, and realize the miniaturization, lightweight and convenience of the product.
