Therefore, they should not be construed as limitations on the embodiments of this application.

[0075] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0076] In the embodiments of this application, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in the embodiments of this application can be understood according to the specific circumstances.

[0077] In some embodiments, refer to Figures 1 to 4 As shown, this application provides a plug connector, including: a plug housing 1, a first power terminal 2, a second power terminal 3, and a plurality of first interchangeable inserts 4. The first power terminal 2 and the second power terminal 3 are disposed within the plug housing 1; one of the plurality of first interchangeable inserts 4 is selectively disposed within the plug housing 1, and the plurality of first interchangeable inserts 4 are used to transmit different media.

[0078] Specifically, the plug housing 1 serves as the external protective and support frame for the entire connector. It not only provides physical protection for the internal components but also ensures the stability and durability of the overall structure. The first power terminal 2 and the second power terminal 3 are located within the plug housing 1 and can represent positive and negative poles, respectively, for transmitting power. They are the core components of the connector responsible for current transmission. Each of the multiple first interchangeable inserts 4 is designed to transmit different media (e.g., different types of current, signals, fluids, etc.). By selecting one insert and installing it into the plug housing 1, the connector's function can be flexibly adjusted according to actual needs.

[0079] It is understandable that the working principle of the plug connector in this application is based on its modular design concept, that is, to adapt to different usage scenarios by replacing different interchangeable inserts. Specifically: when it is necessary to transmit a specific type of medium such as current, signal, gas or liquid, the user can select and install the corresponding first interchangeable insert 4.

[0080] Therefore, this design in the embodiments of this application greatly improves the versatility and flexibility of the plug connector, enabling it to play a role in a variety of application scenarios, expanding from traditional power transmission to more complex fields such as data and signal transmission.

[0081] In some embodiments, refer to Figures 2 to 4 As shown, the first interchangeable insert 4 includes a first insert shell 5 and a first transmission component. The first insert shell 5 is detachably disposed in the plug housing 1, and the first transmission component is disposed on the first insert shell 5. Each first transmission component is a third power terminal 6, a plurality of first male signal pins 7, a first signal pin combination having a plurality of second male signal pins 8 and a plurality of second female signal pins 9, and a first fluid transmission tube (not shown in the figure).

[0082] Specifically, the first insert 5 is detachably disposed inside the plug housing 1, allowing the user to easily replace different first interchangeable inserts 4 as needed. For example, the outer walls of the first insert 5 are respectively provided with limiting grooves 10, and the inner walls of the plug housing 1 are provided with limiting protrusions. During installation, the limiting grooves 10 of the first insert 5 can be aligned with the limiting protrusions of the plug housing 1, thereby pushing the first interchangeable insert 4 into the plug housing 1.

[0083] The first transmission element is mounted on the first housing 5, and can be configured differently according to specific requirements, including but not limited to the following types:

[0084] The third power terminal 6, together with the first power terminal 2 and the second power terminal 3, forms a 3-pin power terminal, which can be used to transmit three-phase power.

[0085] Multiple first public signal pins (e.g., 6) are combined with the first power terminal 2 and the second power terminal 3 to form a 2PIN power terminal + multiple PIN signal pins, which can be used to transmit power, signals and other media, and are suitable for application scenarios that require high bandwidth data transmission.

[0086] A first signal pin combination comprising multiple (e.g., two) second male signal pins 8 and multiple (e.g., two) second female signal pins 9, which, together with the first power terminal 2 and the second power terminal 3, form a 2PIN power terminal + multiPIN signal pin combination, wherein the second male signal pins 8 can transmit current or signal, and the second female signal pins 9 can transmit signal or current. This design enables multi-functional transmission within a single connector.

[0087] The first fluid transmission tube, combined with the first power terminal 2 and the second power terminal 3, forms a 2PIN power terminal + fluid transmission tube: in addition to power and signal transmission, it can also transmit gas and liquid media, such as cooling gas and coolant, which is suitable for application scenarios that require thermal management.

[0088] Therefore, the modular and highly configurable connector design of this application embodiment significantly improves its applicability and flexibility, enabling it to cope with diverse usage scenarios.

[0089] In some embodiments, refer to Figures 1 to 4 As shown, the plug connector also includes a first fixing clip 11, which is disposed at the tail end of the plug housing 1. When the first transmission element is a third power terminal 6, the wires 12 of the first power terminal 2, the second power terminal 3, and the third power terminal 6 pass through the first fixing clip 11. When the first transmission element is a plurality of first male signal pins 7, the wires 12 of the first power terminal 2 and the second power terminal 3, as well as the plurality of first male signal pins 7, pass through the first fixing clip 11. When the first transmission element is a combination of first signal pins, the wires 12 of the first power terminal 2 and the second power terminal 3, as well as the combination of first signal pins, pass through the first fixing clip 11. When the first transmission element is a first fluid transmission tube, the wires 12 of the first power terminal 2 and the second power terminal 3, as well as the first fluid transmission tube, pass through the first fixing clip 11.

[0090] Specifically, the tail end of the plug housing 1 is provided with a first mounting groove. The first fixing clip 11 includes a first clamping body 13 and a second clamping body 14 spliced ​​together in the first mounting groove. The first clamping body 13 and the second clamping body 14 can be fastened by screws or other fasteners, thereby clamping the above-mentioned components to prevent loosening or disconnection caused by vibration or external force, and ensuring the stability and safety of the electrical connection of each component.

[0091] In some embodiments, refer to Figures 1 to 4 As shown, the plug housing 1 has a first opening at its tail end. The plug connector also includes a first sealing gasket 15, which is sealed within the first opening and sandwiched between the first insert 5 and the first fixing clip 11. When the first transmission element is a third power terminal 6, the wires 12 of the first power terminal 2, the second power terminal 3, and the third power terminal 6 pass through the first sealing gasket 15. When the first transmission element is a plurality of first male signal pins 7, the wires 12 of the first power terminal 2 and the second power terminal 3, as well as the plurality of first male signal pins 7, pass through the first sealing gasket 15. When the first transmission element is a combination of first signal pins, the wires 12 of the first power terminal 2 and the second power terminal 3, as well as the combination of first signal pins, pass through the first sealing gasket 15. When the first transmission element is a first fluid transmission tube, the wires 12 of the first power terminal 2 and the second power terminal 3, as well as the first fluid transmission tube, pass through the first sealing gasket 15.

[0092] Specifically, the tail end of the plug housing 1 is provided with a first opening to facilitate the installation of components such as the power terminal, wire 12, first interchangeable insert 4, and first sealing gasket 15. The first sealing gasket 15 is stably clamped between the first insert 5 and the first fixing clip 11. The first sealing gasket 15 can be made of a material with good elasticity and corrosion resistance (such as silicone or rubber), which can effectively prevent moisture and other external substances (such as dust, debris, etc.) from entering the plug connector, improve the sealing performance of the entire plug connector, thereby extending the service life of the connector and reducing the maintenance frequency.

[0093] Therefore, by introducing the first sealing gasket 15, the waterproof performance of the plug connector is enhanced, significantly improving the overall reliability and durability.

[0094] In some embodiments, refer to Figure 1 As shown, a sealing ring 16 is fitted on the outer wall of the front end of the plug housing 1.

[0095] Specifically, a sealing groove is provided on the outer wall of the front end of the plug housing 1, and a sealing ring 16 is fitted and fixed in the sealing groove. The sealing ring 16 can be made of a material with good elasticity and corrosion resistance (such as silicone or rubber), which can provide a reliable sealing effect under compression. When the front end of the plug housing 1 is inserted into the socket housing 22 of the socket connector, the sealing ring 16 is compressed to form a tight sealing layer, preventing moisture and other external contaminants from entering the interior of the connector.

[0096] Therefore, by using the sealing ring 16, the connection between the plug connector and the socket connector can achieve good sealing and waterproofing, allowing the connector to be used in a wider range of environments, including harsh conditions such as high humidity and rain.

[0097] In some embodiments, refer to Figure 1 As shown, the plug housing 1 has latches 17 on both sides.

[0098] Specifically, the latches 17 are located on both sides of the plug housing 1 and can be made of a material with sufficient strength and elasticity (such as plastic or metal) to maintain their shape and function during repeated insertion and removal. In one example, the latches 17 can be metal springs, one end of which has a locking interface 18. Figure 9 and Figure 10 As shown, the socket housing 22 of the socket connector has protruding locking portions 49 on both sides. When the plug housing 1 mates with the socket housing 22, the snap-fit ​​interface 18 of the metal spring engages with the locking portion 49, ensuring that the plug connector can be firmly locked after insertion, preventing accidental loosening or detachment. When unlocking is required, simply press down on the metal spring, making it very convenient to use.

[0099] Therefore, by introducing the locking design 17, the embodiments of this application not only improve the assembly stability of the plug connector and the socket connector, but also significantly enhance the overall safety and reliability.

[0100] In some embodiments, refer to Figure 1 As shown, the plug housing 1 includes a first accommodating cavity 19, a second accommodating cavity 20 and a third accommodating cavity 21 that are separated from each other. The first power terminal 2 is disposed in the first accommodating cavity 19, the first interchangeable insert 4 is disposed in the second accommodating cavity 20 and the second power terminal 3 is disposed in the third accommodating cavity 21.

[0101] Specifically, the accommodating cavities are separated by insulating material, which can be made of plastic or rubber with good insulating properties to ensure electrical isolation between the cavities. This application improves the creepage distance between conductive components by placing the first power terminal 2, the second power terminal 3, and the first interchangeable insert 4 in different accommodating cavities. This design effectively prevents arcing that may occur under high voltage conditions, improves the high voltage resistance of the plug connector, and thus enhances the overall electrical performance.

[0102] The socket connector provided in this application will now be described.

[0103] In some embodiments, refer to Figures 5 to 10 As shown, this application also provides a socket connector for mating with the plug connector of the above embodiment. The socket connector includes: a socket housing 22, a fourth power terminal 23, a fifth power terminal 24, and a plurality of second interchangeable inserts 25. The fourth power terminal 23 and the fifth power terminal 24 are disposed within the socket housing 22; one of the plurality of second interchangeable inserts 25 is selectively disposed within the socket housing 22, and the plurality of second interchangeable inserts 25 are used to transmit different media; the front end of the socket housing 22 abuts against the front end of the plug housing 1, the fourth power terminal 23 abuts against the first power terminal 2, the fifth power terminal 24 abuts against the second power terminal 3, and the second interchangeable inserts 25 abut against the first interchangeable insert 4.

[0104] Specifically, the socket housing 22 is the main structural part of the socket connector, used to house and protect the internal components, ensuring proper alignment and connection between the power terminals and interchangeable inserts. During assembly, the front end of the plug housing 1 is inserted into the front end of the socket housing 22, allowing for a tight connection.

[0105] The fourth power terminal 23 and the fifth power terminal 24 are located inside the socket housing 22, corresponding to the first power terminal 2 and the second power terminal 3 in the plug connector, respectively, and are responsible for power transmission. When the plug connector is inserted into the socket connector, the fourth power terminal 23 mates with the first power terminal 2, and the fifth power terminal 24 mates with the second power terminal 3, ensuring the stability and reliability of the power transmission path.

[0106] Multiple second interchangeable inserts 25 are disposed within the socket housing 22, similar to the first interchangeable insert 4 in the plug connector. These inserts can be replaced according to specific needs to achieve different types of media transmission (such as power, signal, fluid, etc.). When the plug connector is inserted into the socket connector, the second interchangeable inserts 25 mate with the first interchangeable insert 4 to ensure matching and stability of different media transmission paths.

[0107] Therefore, the socket connector provided in this application embodiment is used to mate with the plug connector, and by introducing multiple second interchangeable inserts 25, different media can be transmitted. It can be selected and replaced according to actual needs, so that the connector can flexibly cope with various usage scenarios and significantly improve the multifunctionality and adaptability of the connector.

[0108] In some embodiments, refer to Figures 6 to 8 As shown, the second interchangeable insert 25 includes a second insert housing 26 and a second transmission element. The second insert housing 26 is detachably disposed within the socket housing 22, and the second transmission element is disposed on the second insert housing 26. Each of the second transmission elements is a sixth power terminal 27, a plurality of first female signal pins 28, a second signal pin combination having a plurality of third male signal pins 29 and a plurality of third female signal pins 30, and a second fluid transmission tube (not shown in the figure).

[0109] Specifically, the design of the second interchangeable insert 25 is similar to that of the first interchangeable insert 4. When the plug connector is inserted into the socket connector, the second interchangeable insert 25 and the first interchangeable insert 4 mate and connect. For example, the sixth power terminal 27 connects with the third power terminal 6 to ensure the continuity of the power transmission path. Multiple first female signal pins 28 connect with multiple first male signal pins 7 to ensure the stability of data signal transmission. The third male signal pin 29 and the third female signal pin 30 in the second signal pin assembly connect with the second female signal pin 9 and the second male signal pin 8 in the first signal pin assembly, respectively, to achieve bidirectional signal transmission. The second fluid transmission tube connects with the first fluid transmission tube to ensure the unobstructed flow of the liquid medium transmission path.

[0110] Therefore, this application can realize multiple media transmission functions through the replaceable first interchangeable insert 4 and second interchangeable insert 25 to meet the needs of different application scenarios.

[0111] In some embodiments, refer to Figures 5 to 8As shown, the socket connector also includes a second fixing clip 31, which is located at the tail end of the socket housing 22. When the second transmission element is the sixth power terminal 27, the wires 12 of the fourth power terminal 23, the fifth power terminal 24, and the sixth power terminal 27 pass through the second fixing clip 31. When the second transmission element is a plurality of first female signal pins 28, the wires 12 of the fourth power terminal 23 and the fifth power terminal 24, as well as the plurality of first female signal pins 28, pass through the second fixing clip 31. When the second transmission element is a combination of second signal pins, the wires 12 of the fourth power terminal 23 and the fifth power terminal 24, as well as the combination of second signal pins, pass through the second fixing clip 31. When the second transmission element is a second fluid transmission tube, the wires 12 of the fourth power terminal 23 and the fifth power terminal 24, as well as the second fluid transmission tube, pass through the second fixing clip 31.

[0112] Specifically, the socket housing 22 has a second mounting groove 32 at its tail end. The second fixing clip 31 includes a third clip 33 and a fourth clip 34 that are spliced ​​together in the second mounting groove 32. The third clip 33 and the fourth clip 34 can be fastened by screws or other fasteners to clamp the above-mentioned components, prevent loosening or disconnection caused by vibration or external force, and ensure the stability and safety of the electrical connection of each component.

[0113] In some embodiments, refer to Figures 5 to 8 As shown, the socket housing 22 has a second opening at its tail end. The socket connector also includes a second sealing gasket 35, which is sealed within the second opening and sandwiched between the second insert 26 and the second fixing clip 31. When the second transmission element is the sixth power terminal 27, the wires 12 of the fourth power terminal 23, the fifth power terminal 24, and the sixth power terminal 27 pass through the second sealing gasket 35. When the second transmission element is a plurality of first female signal pins 28, the wires 12 of the fourth power terminal 23 and the fifth power terminal 24, as well as the plurality of first female signal pins 28, pass through the second sealing gasket 35. When the second transmission element is a combination of second signal pins, the wires 12 of the fourth power terminal 23 and the fifth power terminal 24, as well as the combination of second signal pins, pass through the second sealing gasket 35. When the second transmission element is a second fluid transmission tube, the wires 12 of the fourth power terminal 23 and the fifth power terminal 24, as well as the second fluid transmission tube, pass through the second sealing gasket 35.

[0114] Specifically, the rear end of the socket housing 22 is provided with a second opening to facilitate the installation of components such as the power terminals, wires 12, the second interchangeable insert 25, and the second sealing gasket 35. The second sealing gasket 35 is stably clamped between the second insert 26 and the second fixing clip 31. The second sealing gasket 35 can be made of a material with good elasticity and corrosion resistance (such as silicone or rubber), which can effectively prevent moisture and other external substances (such as dust, debris, etc.) from entering the interior of the socket connector, improve the overall sealing performance of the socket connector, thereby extending the service life of the connector and reducing the maintenance frequency.

[0115] Therefore, by introducing a second sealing gasket 35, the waterproof performance of the socket connector is enhanced, significantly improving the overall reliability and durability.

[0116] In some embodiments, refer to Figure 6 and Figure 10 As shown, the socket housing 22 includes a fourth accommodating cavity 36, a fifth accommodating cavity 37 and a sixth accommodating cavity 38 that are separated from each other. The fourth power terminal 23 is disposed in the fourth accommodating cavity 36, the second interchangeable insert 25 is disposed in the fifth accommodating cavity 37 and the fifth power terminal 24 is disposed in the sixth accommodating cavity 38.

[0117] Specifically, the accommodating cavities are separated by insulating material, which can be made of plastic or rubber with good insulating properties to ensure electrical isolation between the cavities. This application improves the creepage distance between conductive components by placing the fourth power terminal 23, the fifth power terminal 24, and the second interchangeable insert 25 in different accommodating cavities. This design effectively prevents arcing that may occur under high voltage conditions, improves the high voltage resistance of the socket connector, and thus enhances the overall electrical performance.

[0118] In some embodiments, refer to Figure 1 , Figure 2 , Figure 6 and Figure 10 As shown, the first receiving cavity 19 and the third receiving cavity 21 of the plug housing 1 are respectively provided with a first mating part 39. The first mating part 39 is provided with a first receiving groove 40 with an opening on one side. One end of the first power terminal 2 and the second power terminal 3 both extend into their respective first receiving grooves 40. When the plug housing 1 is inserted into the socket housing 22, the two first mating parts 39 are inserted into the fourth receiving cavity 36 and the sixth receiving cavity 38 respectively. At this time, the fourth power terminal 23 is mated with the first power terminal 2, and the fifth power terminal 24 is mated with the second power terminal 3.

[0119] Furthermore, when the first transmission component is the third power terminal 6 and the second transmission component is the sixth power terminal 27, one end of the first housing 5 is provided with a second mating portion 41, the second mating portion 41 is provided with a second receiving groove 42 with an opening on one side, one end of the third power terminal 6 extends into the second receiving groove 42, one end of the second housing 26 is provided with a second mating cavity 43, one end of the sixth power terminal 27 extends into the second mating cavity 43, when the plug housing 1 is inserted into the socket housing 22, the second mating portion 41 mates with the second mating cavity 43, and the third power terminal 6 mates with the sixth power terminal 27.

[0120] In addition, the walls of the first accommodating cavity 19 and the third accommodating cavity 21 are respectively provided with protrusions 44, and the walls of the fourth accommodating cavity 36 and the sixth accommodating cavity 38 are provided with grooves 45 that are adapted to the protrusions 44. When the plug housing 1 is inserted into the socket housing 22, the protrusions 44 are embedded in the grooves 45. Furthermore, the protrusions 44 and the grooves 45 can be designed in various colors to achieve a one-to-one correspondence, that is, housings of different colors cannot be inserted into each other, thereby achieving a foolproof design and improving assembly accuracy.

[0121] In some embodiments, refer to Figure 9 As shown, the socket housing 22 has first fastening holes 46 on both sides, and the assembled connector can be fixed to the electronic device by fastening screws or other fasteners through the first fastening holes 46.

[0122] Reference Figure 10 As shown, the socket housing 22 is provided with a flange 47, the flange 47 is provided with a second fastening hole 48, and a third sealing gasket (not shown in the figure) for waterproofing is installed on the back side of the flange 47. The assembled connector can be fixed to the electronic device by passing through the second fastening hole 48 and the third sealing gasket with fasteners such as screws.

[0123] In some embodiments, refer to Figure 1 and Figure 5 As shown, this application also provides a connector module, including: a plug connector and a socket connector as described in the above embodiments, wherein the plug connector and the socket connector are mated.
