[0024] Please see Figures 1 to 7 This application provides a micro rectangular electrical connector, which may include a socket 1 and a plug 2. The socket 1 includes a socket base with various types of sockets, each with a different cross-sectional area. The plug 2 includes a plug base with various types of pins corresponding to the various sockets, each with a different cross-sectional area. The pins can be inserted into their corresponding sockets.

[0025] Specifically, by setting sockets with different cross-sectional areas on the socket base and setting pins corresponding to the sockets on the plug base, when the plug is inserted into the socket, the pins with different cross-sectional areas are inserted into the sockets respectively. Since the pins with different cross-sectional areas can transmit different rated currents, the function of multi-current mixing is realized.

[0026] Please see Figure 1 , Figure 2 In some possible implementations, the multiple sockets include two first sockets 11, and a plurality of second sockets 12 and a plurality of third sockets 13 arranged sequentially between the two first sockets 11, wherein the cross-sectional areas of the first sockets 11, second sockets 12 and the plurality of third sockets 13 are different; the multiple pins include two first pins 21, and a plurality of second pins 22 and a plurality of third pins 23 arranged sequentially between the two first pins 21, wherein the cross-sectional areas of the first pins 21, second pins 22 and third pins 23 are different; wherein the first pins 21 correspond to the first sockets 11 and can be inserted into the first sockets 11; the second pins 22 correspond to the second sockets 12 and can be inserted into the second sockets 12; and the third pins 23 correspond to the third sockets 13 and can be inserted into the third sockets 13.

[0027] In this embodiment, by setting a first socket 11, a second socket 12, and a third socket 13 with different cross-sectional areas, and setting a first pin 21, a second pin 22, and a third pin 23 corresponding to the above sockets, different currents can be effectively transmitted, thereby realizing the function of multi-current mixing.

[0028] Furthermore, the cross-sectional shape of the socket is an asymmetrical irregular shape. During insertion, the plug 2 can only be inserted into the socket 1 in one direction, and cannot be inserted into the socket 1 in the opposite direction. Insertion is only possible when the plug 2 and the socket 1 are compatible.

[0029] Furthermore, micro rectangular electrical connectors include various types, with different shapes and / or sizes of the jacks and pins on different types of micro rectangular electrical connectors.

[0030] In this embodiment, the cross-section of the pins on different types of micro rectangular connectors can be semi-circular, polygonal, or other irregular shapes. Correspondingly, the cross-sectional shape of the socket corresponds to the pin, and the size of both can be adjusted according to actual conditions. This arrangement can effectively prevent mis-insertion of different types of micro rectangular connectors.

[0031] Please see Figure 1 , Figure 2 In some possible implementations, the socket base is further provided with two fixed end locking components 14, which are located at both ends of the socket base respectively; the plug base is further provided with two free end locking components 24, which are located at both ends of the plug base respectively; wherein, the two free end locking components 24 can be connected to the two fixed end locking components 14 respectively.

[0032] In this embodiment, by setting the fixed end locking component 14 and the free end locking component 24, the plug 2 can be locked after it is connected to the socket 1, preventing the connection from becoming loose or disconnected due to vibration or external force, thereby ensuring the stability and reliability of the electrical connection.

[0033] Specifically, after the plug 2 and socket 1 are connected in place, the free end locking component 24 and the fixed end locking component 14 are connected and locked to achieve a stable connection between the plug 2 and socket 1. This locking method is not only easy to operate, but also has a reliable locking effect, which can effectively improve the safety of the electrical connector.

[0034] Please see Figure 4 In some possible implementations, the fixed end locking assembly 14 may include a fixed screw 15 and a mating barrel 16, wherein one end of the fixed screw 15 is threaded to the socket base; the mating barrel 16 is disposed at the other end of the fixed screw 15, the inner wall of the mating barrel 16 is provided with threads, and the free end locking assembly 24 is threaded to the inner wall of the mating barrel 16.

[0035] The fixing screw 15 is securely fixed to the socket base via a threaded connection, providing a solid foundation for the entire locking assembly. The mating barrel 16 is located at the other end of the fixing screw 15, and its threaded inner wall allows the free-end locking assembly 14 to connect tightly with it. This threaded connection not only ensures a stable connection but also facilitates quick installation and disassembly, improving the ease of use of the electrical connector. When it is necessary to lock the plug 2 to the socket 1, simply screw the free-end locking assembly 24 into the mating barrel 16 to complete the locking operation.

[0036] Please see Figure 3 , Figure 4 In some possible implementations, a groove 17 is also provided on the inner wall of the mating barrel 16. The free end locking assembly 24 may include: a rivet tube 25, a screw 26, and a boss 27. The screw 26 is provided at the end of the rivet tube 25; the boss 27 is provided at the end of the rivet tube 25 and is located on the side where the screw 26 and the rivet tube 25 are connected. The screw 26 can be connected to the inside of the mating barrel 16, and when the screw 26 is connected to the inside of the mating barrel 16, the boss 27 is engaged in the groove 17.

[0037] In this embodiment, a groove 17 is provided on the inner wall of the mating barrel 16, and a boss 27 is provided at the end of the rivet 25 of the free end locking assembly 24. When the screw 26 is screwed into the mating barrel 16, the boss 27 will simultaneously embed into the groove 17, forming a mechanical limiting structure. This dual locking mechanism (threaded connection + boss limiting) not only enhances the locking strength but also effectively prevents the screw 26 from loosening due to vibration or external force. In actual operation, the user only needs to align the screw 26 of the free end locking assembly 24 with the mating barrel 16 and screw it in until the screw 26 is completely screwed into the mating barrel 16. Compared with the traditional single-thread locking method, this design greatly improves the tensile strength of the connection.

[0038] Furthermore, micro rectangular electrical connectors include various types, and the shapes of the grooves 17 and bosses 27 on different types of micro rectangular electrical connectors are different.

[0039] Specifically, the groove 17 can be an irregular groove, and the boss 27 can be an irregular boss. By setting irregular grooves 17 with different angles and corresponding unique irregular bosses 27, it is possible to effectively prevent mis-insertion and ensure that the normal use of the equipment is not affected by mis-insertion.

[0040] Please see Figure 4 In some possible implementations, a flat washer 18, a spring washer 19, and a nut 110 are also sequentially provided on the fixing screw 15.

[0041] The flat washer 18 increases the contact area between the fixing screw 15 and the socket base, dispersing pressure and preventing damage to the socket base surface due to excessive local pressure. The spring washer 19, through its elastic deformation capability, provides continuous spring force after the nut 110 is tightened, keeping the nut 110 firmly in place and effectively preventing it from loosening due to vibration or external forces. The nut 110 is threaded onto the fixing screw 15, and the tightening force can be adjusted by rotating the nut 110, ensuring a secure and reliable connection between the fixing end locking assembly 14 and the socket base. This multi-layered protection design significantly improves the stability of the electrical connector in complex environments.

[0042] Please see Figure 1 , Figure 2 In some possible implementations, a socket housing 111 is provided on the socket base, and a plug housing 28 is provided on the plug base, the plug housing 28 being able to fit into the socket housing 111.

[0043] In this embodiment, a socket housing 111 is provided on the socket base, and a plug housing 28 is provided on the plug base, allowing the plug housing 28 to fit inside the socket housing 111, forming a complete protective structure. The socket housing 111 and plug housing 28 not only effectively prevent dust, moisture, and other external impurities from entering the electrical connector, protecting internal electrical components from environmental influences, but also provide cushioning protection when the electrical connector is subjected to external impacts, reducing mechanical damage. Simultaneously, this housing adaptation design ensures accurate positioning when the plug and socket are connected, improving connection efficiency. In practical applications, users simply align the plug housing 28 with the socket housing 111 and insert it to achieve a quick and accurate connection between the plug and socket, while obtaining excellent protection.

[0044] Please see Figure 7 In some possible implementations, the socket housing 111 may include: a first horizontal segment 112, a first connecting segment 113, a second horizontal segment 114, and a second connecting segment 115, wherein one end of the first connecting segment 113 is smoothly connected to the first horizontal segment 112; the second horizontal segment 114 is smoothly connected to the other end of the first connecting segment 113; and one end of the second connecting segment 115 is smoothly connected to the second horizontal segment 114, and the other end is smoothly connected to the first horizontal segment 112.

[0045] Specifically, this segmented structural design allows the socket housing 111 to maintain overall strength while possessing better flexibility. The first horizontal segment 112 and the second horizontal segment 114 achieve a smooth transition through the first connecting segment 113 and the second connecting segment 115, forming a continuous protective curved surface. When the electrical connector is subjected to lateral impact, the smoothly connected curved surface structure can disperse stress, avoiding housing breakage caused by localized stress concentration. At the same time, this streamlined design can also reduce the accumulation of dust and moisture, further improving protective performance. During actual assembly, the smooth connection between each segment ensures a tight fit between the housing and the socket base, effectively preventing protective failure caused by assembly gaps.

[0046] Furthermore, in some possible implementations, the angle between the second connecting segment 115 and the second horizontal segment 114 is 30° to 45°.

[0047] In this embodiment, the included angle between the second connecting segment 115 and the second horizontal segment 114 can be 30°, 35°, 40°, 45°, etc. This design makes the shapes of the first connecting segment 113 and the second connecting segment 115 different, effectively avoiding mis-insertion.

[0048] Furthermore, in some possible implementations, the second socket 12 is provided with 4 sockets, and the third socket 13 is provided with 36 sockets.

[0049] Specifically, the first socket 11 is equipped with two sockets that can transmit two 20A currents, the second socket 12 is equipped with four sockets that can transmit four 5A currents, and the third socket 13 is equipped with 36 sockets that can transmit 36 ​​3A currents.

[0050] It should be noted that the number of the first socket 11, the second socket 12, and the third socket 13 can be set according to the specific transmission current.

[0051] Furthermore, in some possible implementations, the diameter of the first socket 11 is 3.4 mm, the diameter of the second socket 12 is 1.5 mm, and the diameter of the third socket 13 is 0.94 mm.

[0052] The first socket 11 features a 3.4mm diameter design, which not only meets the 20A high-current transmission requirement but also prevents mis-insertion through its non-circular cross-section. The second socket 12 has a 1.5mm diameter that precisely accommodates 5A current transmission, and its four sockets enable multi-channel power supply. The third socket 13 features a 0.94mm micro-hole design that ensures stable transmission of 3A current for 36 channels while optimizing space utilization through dense arrangement. This differentiated aperture design not only distinguishes current levels but also creates a natural anti-mis-insertion mechanism through physical size differences. Combined with the aforementioned non-circular cross-section structure, it provides double protection, effectively avoiding the risk of incorrect insertion of pins of different current levels.

[0053] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
