[0014] Compared with existing technologies, the technical effect achieved by adopting this technical solution is that the plug segment, as the interface with the external socket, realizes the core conductive function of the plug.
[0015] In one embodiment of this utility model, a limiting slot is provided on the side of the mating part away from the pin bracket; a vertical axis is provided along the length direction of the mating part; when the insertion section rotates at a first angle along the vertical axis, the insertion section abuts against the limiting wall of the limiting slot.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
[0041] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a connection, or an integral connection; 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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0042] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0043] See Figure 1 , Figure 1 This is a schematic diagram of the structure of a plug provided in an embodiment of the present utility model; combined with Figures 2 to 8 Specifically, the plug 100 includes: a pin 30 and a connecting sleeve 20; the top of the pin 30 has a mating section 31, and the mating section 31 is provided with a mating groove 311; the top of the connecting sleeve 20 has a flange; the mating section 31 is inserted into the connecting sleeve 20, and the side wall of the connecting sleeve 20 is compressed and embedded in the mating groove 311.
[0044] Specifically, the top of the pin 30 is integrally formed with a mating section 31, and an annular mating groove 311 is provided on the mating section 31; the connecting sleeve 20 is a hollow cylindrical structure, and its top extends outward to form a flange; during assembly, the mating section 31 is inserted into the connecting sleeve 20 along the axial direction, and radial pressure is applied to the side wall of the connecting sleeve 20 by an external stamping device, causing the side wall of the connecting sleeve 20 to deform, and part of the structure is embedded in the mating groove 311.
[0045] For further information, please refer to [link / reference]. Figure 3 and Figure 8 The connecting sleeve 20 is provided with a stamping part 21 corresponding to the mating groove 311; when a stamping force is applied to the stamping part 21, the side wall of the stamping part 21 is embedded in the mating groove 311.
[0046] Based on actual usage, the connecting sleeve 20 is provided with a stamping part 21 at the position corresponding to the mating groove 311; when a stamping force is applied to the stamping part 21, the material of the stamping part 21 is more likely to deform towards the mating groove 311; compared with stamping the entire connecting sleeve 20, providing a dedicated stamping part 21 on the connecting sleeve 20 can reduce the deformation of non-target areas and improve the overall fitting accuracy.
[0047] Preferably, the mating section 31 is an I-shaped structure.
[0048] Please see Figure 7 The mating section 31 has an I-shaped structure, that is, the mating section 31 includes an upper step, a lower step and an intermediate column connecting the two. The mating groove 311 is located at the transition between the intermediate column and the upper and lower steps. Furthermore, the upper and lower steps can respectively form axial limits on the inner wall of the connecting sleeve 20 to prevent the pin 30 from moving along the axis of the connecting sleeve 20.
[0049] For further information, please refer to [link / reference]. Figure 2 and Figure 3 The plug 100 also includes: a pin bracket 10 and a mating part 12; the mating part 12 is disposed on one side of the pin bracket 10; the connecting sleeve 20 is disposed in the mating part 12, and the mating part 12 is provided with a clearance notch 121 corresponding to the stamping part 21.
[0050] Preferably, the pin 30 is rotatably connected to the connecting sleeve 20.
[0051] Please see Figure 2 and Figure 3 The mating part 12 has a cylindrical structure and is fixed to one side of the pin bracket 10. The connecting sleeve 20 is disposed inside the mating part 12, and the side wall of the mating part 12 is provided with a clearance notch 121 corresponding to the stamping part 21. The clearance notch 121 provides space for the deformation of the stamping part 21, avoiding the mating part 12 from blocking the stamping path and effectively solving the problem of stamping operation being blocked. At the same time, the mating part 12 and the pin bracket 10 provide overall support for the connecting sleeve 20 and the pin 30, improving the structural strength of the plug 100.
[0052] Please refer to the specific circumstances. Figure 2 and Figure 3The pin bracket 10 serves as the basic load-bearing structure, and its mating part 12 is specially designed with a clearance notch 121, which reserves space for subsequent stamping operations. The connecting sleeve 20 is installed on the pin bracket 10, and part of its structure is exposed at the clearance notch 121, which facilitates the application of external stamping pressure. The pin 30 is assembled inside the connecting sleeve 20 and can rotate relative to the connecting sleeve 20. This rotating connection method allows the plug 100 to flexibly adjust its angle during use. When it is necessary to fix the pin 30 to the pin bracket 10, stamping pressure is applied to the exposed part of the connecting sleeve 20 through the clearance notch 121 of the pin bracket 10. Under the action of stamping pressure, the connecting sleeve 20 deforms and abuts tightly against the pin 30, thereby firmly fixing the pin 30 to the pin bracket 10. This fixing method avoids the problem of insecure fixing caused by the small target size in the traditional flanging process, and improves the stability of the connection.
[0053] Furthermore, the plug 100 also includes a fixing member, which is located on the side of the pin bracket 10 away from the connecting sleeve 20; the fixing member is used to fix the connecting sleeve 20 to the pin bracket 10.
[0054] Preferably, the fastener is made of insulating material.
[0055] For further information, please refer to [link / reference]. Figure 4 and Figure 7 The pin 30 also includes a plug section 32; the plug section 32 is located on the side of the mating section 31 opposite to the pin bracket 10.
[0056] Specifically, the mating section 31 and the plug section 32 are integrally formed to form the pin part 30. The plug section 32 is a conductive metal rod, which is located on the side of the mating section 31 away from the pin bracket 10.
[0057] For further information, please refer to [link / reference]. Figure 5 The mating part 12 has a limiting slot on the side away from the pin bracket 10; a vertical axis 123 is provided along the length of the mating part 12; when the insertion section 32 rotates at a first angle along the vertical axis 123, the insertion section 32 abuts against the limiting wall 122 of the limiting slot.
[0058] Specifically, the mating part 12 is provided with a limiting slot corresponding to the plug section 32 so that the plug section 32 can adapt to plugs of various angles; while the limiting wall 122 prevents the plug section 32 from rotating excessively by mechanical limiting, which can effectively prevent structural damage to the plug 100 due to excessive rotation angle.
[0059] For further information, please refer to [link / reference]. Figures 1 to 4 The plug 100 also includes: a connecting piece 13, which is disposed on the pin bracket 10; the connecting sleeve 20 presses the connecting piece 13 into the mating part 12 for supplying power to the other plug 100.
[0060] Specifically, the connecting piece 13 is a conductive metal sheet and is disposed on the plug bracket 10. When the connecting sleeve 20 is assembled into the mating part 12, the flange of the connecting sleeve 20 presses one end of the connecting piece 13 into the mating part 12, so that the connecting piece 13 and the plug 30 are electrically connected through the connecting sleeve 20. The other end of the connecting piece 13 is used for external circuit connection, which can realize the power supply function of the other plug 100.
[0061] For further information, please refer to [link / reference]. Figure 3 , Figure 4 and Figure 6 A connecting groove 111 is provided along the length direction of the pin bracket 10; the connecting piece 13 includes a connecting section 132 and a lead-out section 131 connected to the connecting section 132. The connecting section 132 is located in the mating part 12, and the lead-out section 131 is located in the connecting groove 111.
[0062] Specifically, the connecting piece 13 includes an integrally formed connecting section 132 and an outgoing section 131; the connecting section 132 is located inside the mating part 12 and is pressed into contact with the connecting sleeve 20; the outgoing section 131 is bent and extended into the connecting groove 111 and is positioned and fixed by the connecting groove 111.
[0063] Furthermore, the lead-out segment 131 is connected to the socket via a wire to conduct the current from the connection segment 132 into the socket.
[0064] Specifically, the lead-out section 131 of the connecting piece 13 is provided with an adapter structure, which can be connected to a power strip or socket. When the plug 100 in this application is connected to the power supply, the current is transmitted through the pin 30 to the connecting section 132 of the connecting piece 13, and then conducted through the connecting section 132 to the lead-out section 131. The lead-out section 131 conducts the current into the power strip or socket connected to it, thereby supplying power to the power strip or socket. This ensures that the power can be transmitted efficiently and stably from the plug 100 to the power strip or socket.
[0065] Furthermore, this utility model also provides a socket, including the plug 100 in any of the above examples.
[0066] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
