[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0017] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or a connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0018] like Figures 1 to 4 As shown, this utility model embodiment provides a connector power-connecting mating structure, including a first terminal assembly 10, a second terminal assembly 20, and a power-connecting sleeve 30. The three components are nested together to achieve precise mating and stable connection, while ensuring reliable transmission of electrical performance.

[0019] The power-connecting sleeve 30 includes a first insertion end 31 and a second insertion end 32, serving as a connection base for positioning and support. The inner and outer diameters of the first insertion end 31 are both smaller than those of the second insertion end 32, forming a first limiting step 33. The first limiting step 33 provides an axial positioning reference for the first terminal assembly 10 and the second terminal assembly 20, ensuring the accuracy of their mating position. The power-connecting sleeve 30 is also made of conductive material, forming an electromagnetic shielding cavity that effectively blocks external electromagnetic interference and prevents internal signals from radiating outwards, thus improving the stability of signal transmission.

[0020] like Figure 2 and Figure 3 As shown, the first terminal assembly 10 has an L-shaped structure. This structural design can adapt to spatial layout requirements and realize circuit reversal connections. The first terminal assembly 10 includes a first electrical terminal 11 and a first insulating sleeve 12 sleeved on the first electrical terminal 11. Both ends of the first electrical terminal 11 extend through the first insulating sleeve 12. This structural design ensures that the first electrical terminal 11 can establish a connection with the external circuit. The first insulating sleeve 12 is made of high-temperature resistant insulating material, and its function is to achieve electrical isolation between the first electrical terminal 11 and the external structure to prevent short circuits.

[0021] The first electrical terminal 11 has a connecting pin 111 at its horizontal end and a fixing pin 112 at its vertical end. The connecting pin 111 is used to make an electrical connection with the second terminal assembly 20, and the fixing pin 112 is used to make a fixed connection with an external circuit or device to realize the current transmission path.

[0022] The horizontal end of the first insulating kit 12 is provided with a first limiting boss 121. When the horizontal end of the first insulating kit 12 is inserted into the first plug-in end 31 and extends into the second plug-in end 32, the end face of the first plug-in end 31 abuts against the first limiting boss 121, forming an axial limit to prevent the first terminal assembly 10 from being over-inserted. The end face of the horizontal end of the first insulating kit 12 is inserted into the first mating sleeve 21 and abuts against the second insulating kit 24. Physical positioning is achieved through the contact between the insulating kits, while ensuring electrical isolation.

[0023] like Figure 4As shown, during assembly, one end of the first terminal assembly 10 is inserted into the first plug-in end 31 and extends towards the second plug-in end 32. The inner wall of the first plug-in end 31 and the outer wall of the first insulating kit 12 form a tight fit to achieve radial positioning. One end of the second terminal assembly 20 is inserted into the second plug-in end 32 and connected to the first power-connecting terminal 11. The precise docking of the two terminal assemblies is achieved through the overall structure of the power-connecting sleeve 30.

[0024] like Figure 2 and Figure 3 As shown, the second terminal assembly 20 includes a power shield, a second insulating sleeve 24 disposed within the power shield, and a second power terminal 23 disposed within the second insulating sleeve 24. The power shield is made of conductive material, forming an electromagnetic shielding cavity, which can effectively block external electromagnetic interference and prevent internal signals from radiating outward, thereby improving the stability of signal transmission. The second insulating sleeve 24 serves as an insulating barrier, separating the second power terminal 23 from the power shield to prevent short circuits.

[0025] like Figure 3 As shown, the electrical shielding component includes a first pair of insert sleeves 21, a second pair of insert sleeves 22, and a riveted sleeve 25, which work together to form a complete shielding structure. The second insulating kit 24 is located inside the first pair of insert sleeves 21, and the first pair of insert sleeves 21 provide initial shielding.

[0026] The first pair of sleeves 21 includes a first mating section 211 and a second mating section 212, and a first positioning step 213 and a second positioning step 214 are formed at the connection between the two. The first positioning step 213 is located on the outer surface, and the second positioning step 214 is located on the inner surface. The second positioning step 214 is used to mate and position with the second insulating kit 24.

[0027] The first mating section 211 is inserted into the second plug-in end 32, and its end face abuts against the first limiting step 33 to achieve axial positioning. The first mating section 211 has multiple elastic contact pieces 214 evenly distributed around its circumference. These elastic contact pieces 214 have a certain elastic deformation capability. When inserted into the second plug-in end 32, they abut against the inner sidewall to form a tight electrical connection, which not only enhances the stability of the structure but also ensures the continuity of the shielding layer and improves the shielding effect.

[0028] The horizontal end face of the first insulating kit 12 is inserted into the first mating section 211 and abuts against the second insulating kit 24. Precise positioning is achieved through the contact of the two insulating kits, ensuring that the first electrical terminal 11 and the second electrical terminal 23 can be accurately connected.

[0029] The outer surface of the second pair of insert sleeves 22 is provided with a first stop 221, dividing the sleeve into a third mating section 222 and a fourth mating section 223. The third mating section 222 is fitted inside the second mating section 212, realizing the connection with the first pair of insert sleeves 21, and the two cooperate to form a complete shielding cavity. The riveted sleeve 25 is fitted outside the fourth mating section 223 and is stopped and engaged with one side of the first stop 221. The external wire can be fixed on the fourth mating section 223 by the riveting process, while the first stop 221 restricts the position of the riveted sleeve 25 to ensure the reliability of the connection.

[0030] The second insulating kit 24 includes a first insertion section 241 and a second insertion section 242, both having a through insertion hole 243 for accommodating a second electrical terminal 23. The inner and outer diameters of the insertion hole in the first insertion section 241 are smaller than those in the second insertion section 242, forming a second limiting step 244 for positioning the second electrical terminal 23. The first insertion section 241 is disposed within the first mating section 211, and the second insertion section 242 is disposed within the second mating section 212, forming a nested fit with the first pair of plug sleeves 21. The inner surface of the third mating section 222 has a third positioning step 224, which engages with the second insertion section 242 to stop and position the second pair of plug sleeves 22 and the second insulating kit 24.

[0031] The outer surface of the first insertion section 241 is provided with a sealing protrusion 245, which abuts against the inner wall of the first mating section 211 to form a sealing structure. This effectively prevents dust, moisture, and other contaminants from entering the connector, improving its environmental adaptability. The third mating section 222 is sleeved on the outside of the second insertion section 242. One side of the second limiting step 244 engages with the second positioning step 214, and the other side engages with the end face of the third mating section 222. Through multiple engagements, the second insulating kit 24 is precisely positioned in the axial direction, preventing displacement during use.

[0032] like Figure 5 As shown, one end of the second electrical terminal 23 extends a conductive clamp 231, which is disposed within the first insertion section 241. The connecting pin 111 is inserted into the conductive clamp 231. The conductive clamp 231 has a certain degree of elasticity, which can tightly clamp the connecting pin 111 to ensure a reliable electrical connection between the two, while also facilitating insertion and removal operations. The other end of the electrical terminal 23 is provided with a conductive wiring part 232, which is disposed within the second insertion section 242 for connecting to an external wire to realize current transmission.

[0033] The outer surface of the second electrical terminal 23 is also provided with a fastening block 233 and a second stop 234. The fastening block 233 abuts against the inner wall of the first insertion section 241, and the interference fit ensures that the second electrical terminal 23 is fixed in the second insulating kit 24, preventing loosening. The second stop 234 cooperates with the second limiting step 244 to stop and position the second electrical terminal 23, ensuring the accuracy of its axial position and guaranteeing precise docking with the first electrical terminal 11.

[0034] like Figure 6 As shown, this embodiment of the invention also provides a connector 100, which has six sets of the aforementioned connector power-connecting mating structures. Multiple sets of power-connecting mating structures can be provided according to actual needs, with each set operating independently to achieve simultaneous transmission of multiple signals or currents, thereby improving the connector's integration.

[0035] The above description merely illustrates the preferred technical solution of this utility model, and while the description is relatively specific and detailed, it should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and this utility model also intends to include these modifications and variations.
