[0051] Please refer to the attached document. Figures 1-5 In this embodiment, the connecting body 10 is provided with a cylindrical part 11, a limiting part 12, and a locking arm 13; the cylindrical part 11 extends along the length direction of the connecting body 10, and the limiting part 12 protrudes from the peripheral sidewall of the connecting body 10; the locking arm 13 and the limiting part 12 are integrally connected; the connection strength between the locking arm 13 and the limiting part 12 is ensured, and the locking arm 13 and the limiting part 12 are exposed on the outer peripheral side of the connecting body 10.

[0052] The inner core 20 is fitted onto the cylindrical portion 11. The inner core 20 has an elongated groove 20a and a locking groove 20b. The locking groove 20b is located on one side of the elongated groove 20a and connects to the elongated groove 20a. The elongated groove 20a is used for the limiting portion 12 to pass through. At the same time, the locking arm 13 engages with the locking groove 20b as the limiting portion 12 connects with the elongated groove 20a, so as to maintain the static state of the inner core 20 and the connecting body 10. This allows the inner core 20 to guide and engage with the limiting portion 12 through the elongated groove 20a and the locking groove 20b, ensuring the stability of the connection between the inner core 20 and the connecting body 10 and preventing the inner core 20 from moving relative to the connecting body 10.

The contact area of ​​the conductive flat parts 42 is larger, which facilitates the conductive bending member 40 and the adapter to conduct electricity and improves the docking stability of the plug assembly 100.

[0055] In this embodiment, the end of the limiting part 12 is arc-shaped to facilitate its adaptation to the end of the elongated groove 20a, and the arc shape reduces stress concentration. The engaging arm 13 is disposed on the outer periphery of the limiting part 12 and close to its end; the engaging arm 13 and the end of the limiting part 12 are connected by a sloped transition; this sloped transition provides buffering and guiding effects. The engaging arm 13 has a first slope 131, which extends obliquely toward the end of the limiting part 12. When the first slope 131 enters the elongated groove 20a, it is squeezed by the inner wall of the elongated groove 20a and undergoes flexible deformation until it engages with the engaging groove 20b. This ensures that the engaging arm 13 can smoothly enter the elongated groove 20a and ultimately engage in the engaging groove 20b, guaranteeing the connection stability between the inner core 20 and the limiting part 12.

[0056] In this embodiment, a second inclined surface is provided at the end of the engaging groove 20b facing the elongated groove 20a, and the second inclined surface is adapted to the first inclined surface 131; this ensures the smoothness and reliability of the engaging process, while reducing the difficulty of aligning the limiting part 12 and the inner core 20.

[0057] In this embodiment, the plug assembly 100 further includes an outer sleeve 50, which is fitted over the outer side of the inner core 20 and located outside the conductive bending member 40. This allows the outer sleeve 50 to protect the inner core 20 from external physical impacts. The outer sleeve 50 has a clearance hole 50a, which is arranged relative to the conductive plane portion 42 to expose the conductive plane portion 42, allowing the conductive plane portion 42 to contact the conductive contacts of the adapter and ensuring a guiding effect between the conductive plane portion 42 and the adapter. The outer sleeve 50 and the inner core 20 together clamp multiple bending positioning portions 41 to maintain the assembly form of the conductive bending member 40. This allows the multiple bending positioning portions 41 to be restricted in multiple directions, ensuring that the multiple bending positioning portions 41 will not deform or shift.

[0058] The outer cover 50 covers the locking arm 13 and limits the locking arm 13 to prevent it from coming off outward. This allows the outer cover 50 to not only provide protection but also limit the locking arm 13, ensuring that the locking arm 13 remains stable in the locking groove 20b and will not loosen due to external force or vibration.

[0059] In this embodiment, the inner core 20 is provided with an arc-shaped protrusion 21 at its corner; the plurality of bending positioning parts 41 include a first bending positioning part 411, which is located on the right side of the conductive plane part 42.

[0060] In this embodiment, the inner core 20 is provided with a docking groove 20c, which is recessed into the side wall of the inner core 20 along an inclined direction; the docking groove 20c and the arc-shaped boss 21 are distributed on different side walls of the inner core 20; the plurality of bending positioning parts 41 include a second bending positioning part 412, which is located on the upper side of the conductive plane part 42.

[0061] In this embodiment, the inner core 20 is provided with a clamping arm 22, and the clamping arm 22 and the side wall of the inner core 20 form a clamping space; the plurality of bending positioning portions 41 include a third bending positioning portion 413, which is located below the conductive plane portion 42. The third bending positioning portion 413 bends to one side along the conductive plane portion 42 and extends along the length direction of the inner core 20; the third bending positioning portion 413 passes through the clamping space and is clamped by the clamping arm 22; so that the inner side wall of the clamping space restricts the position of the third bending positioning portion 413, ensuring the position of the third bending positioning portion 413 relative to the inner core 20.

[0062] The third bending positioning part 413 and the second bending positioning part 412 are arranged on opposite sides of the conductive plane part 42, so that the conductive plane part 42 is restricted to different positions by the inner core 20 through the first bending positioning part 411, the second bending positioning part 412 and the third bending positioning part 413, thereby ensuring the positional accuracy of the conductive bending part 40 relative to the inner core 20 and ensuring that the conductive bending part 40 will not be deformed or displaced.

[0063] In this embodiment, the peripheral sidewall of the plug 30 is provided with a protrusion 31, which is located in the internal space of the inner core 20 and is limited by the sidewall of the internal space of the inner core 20. This allows the inner sidewall of the inner core 20 to limit the protrusion 31 and prevent it from moving freely within the inner sidewall of the inner core 20. The plug 30 is provided with a stepped portion 32, and an elastic member 33 is provided between the plug 30 and the cylindrical portion 11. The elastic member 33 is sleeved on the plug 30 and elastically contacts the stepped portion 32 and the cylindrical portion 11, so that the plug 30 can move elastically relative to the cylindrical portion 11 through the elastic member 33, thereby facilitating the plug 30 to be plugged into the adapter's socket.

[0064] In this embodiment, the inner core 20 is provided with a wire hole 20d and multiple diversion grooves 20e.
