It consists of a plug body, conductive terminals, etc. It has a structural design to adapt to different interfaces, can stably transmit current and provide safety protection. The specifications vary depending on the charging needs and the type of equipment.

[0003] Existing vehicle charging power cord plugs are prone to falling off after long-term use. This is mainly because frequent plugging and unplugging of the interface causes the elasticity of the internal springs or clips to weaken, resulting in loose contact. Alternatively, gaps may be created between the plug and socket due to vibration and wear, which can affect charging reliability and even cause safety hazards such as short circuits.

[0008] The vehicle charging power cord plug includes a plug connected to the power cord and a socket that matches the plug, with an anti-detachment component installed between the plug and the socket;

[0009] The anti-dislodgement component includes a rotating groove formed on the outer arc surface of the plug. An anti-dislodgement sleeve is rotatably installed inside the rotating groove. The anti-dislodgement sleeve is fitted onto the outside of the plug. Two sets of locking blocks are symmetrically installed on the outer wall of the anti-dislodgement sleeve. The outer arc surface of the socket has a locking groove corresponding to the locking block. After the locking block is inserted into the locking groove, it is rotated and locked in the middle of the locking groove.

[0010] Preferably, metal blocks are embedded in the sidewalls of the two sets of card blocks, and two sets of magnetic blocks are embedded in the sidewalls of the card slots corresponding to the metal blocks, with each set of metal blocks and the corresponding magnetic block attracting each other magnetically.

[0011] Preferably, the magnetic block is installed perpendicular to the card slot inlet direction, and the metal block inside the card block generates a magnetic attraction with the magnetic block through rotation.

[0012] Preferably, each group of metal blocks and magnetic blocks has a conductive lubricating layer on the contact surface, the lubricating layer being used to fill the gap between the metal blocks and magnetic blocks.

[0023] 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.

[0024] This utility model provides: a vehicle charging power cord plug, such as... Figures 1-4 As shown, the device includes a plug 1 connected to a power cord and a socket 2 that matches the plug 1. An anti-detachment component 3 is installed between the plug 1 and the socket 2. The plug 1 connects to the power cord and serves as the front-end component for power transmission; its internal conductive structure is responsible for drawing out the power. The socket 2 matches the plug 1 and is embedded in the vehicle's power interface for connecting with the plug 1 to establish circuit conduction. The anti-detachment component 3 provides an additional mechanical locking effect between the plug 1 and the socket 2, preventing the plug 1 from separating from the socket 2 due to external force or prolonged use.

[0025] The anti-dislodgement component 3 includes a rotating groove 31 formed on the outer arc surface of the plug 1. An anti-dislodgement sleeve 32 is rotatably installed inside the rotating groove 31 and fits over the outside of the plug 1. Two sets of locking blocks 33 are symmetrically installed on the outer wall of the anti-dislodgement sleeve 32. A slot 34 is formed on the outer arc surface of the socket 2 corresponding to the locking blocks 33. After the locking blocks 33 are inserted into the slots 34, they are rotatably engaged in the middle of the slots 34. The rotating groove 31 provides a circumferential rotation track for the anti-dislodgement sleeve 32 while restricting its axial movement, ensuring that the anti-dislodgement sleeve 32 can only rotate around the axis of the plug 1. The anti-dislodgement sleeve 32 is rotatably connected to the rotating groove 31, and the two sets of locking blocks 33 symmetrically installed on its outer wall will move synchronously with the rotation of the anti-dislodgement sleeve 32. The slot 34 in the socket 2 engages the locking blocks 33 in the middle of the anti-dislodgement sleeve 32. When in use, first insert the locking block 33 into the slot 34, then rotate the anti-disengagement sleeve 32. The anti-disengagement sleeve 32 rotates in the rotating groove 31, causing the locking block 33 to slide from the slot 34 inlet to the middle. The locking block 33 and the slot 34 fit together to form a firm mechanical engagement, thereby preventing the plug 1 from being pulled out axially.

[0026] Preferably, metal blocks 35 are embedded in the side walls of the two sets of locking blocks 33, and two sets of magnetic blocks 36 are embedded in the side walls of the slots 34 corresponding to the metal blocks 35. Each set of metal blocks 35 and corresponding magnetic blocks 36 are magnetically attracted to each other. The metal blocks 35 and magnetic blocks 36 have mutual magnetic attraction. When the locking block 33 is inserted into the slot 34, the anti-disengagement sleeve 32 is rotated to align the metal blocks 35 and magnetic blocks 36. The two generate radial clamping force through magnetic attraction, which helps to firmly lock the locking block 33 in the middle of the slot 34, preventing the anti-disengagement sleeve 32 from rotating freely and causing the locking block 33 to fall out of the slot 34, further enhancing the anti-disengagement effect and effectively resisting loosening caused by factors such as vehicle vibration.

[0027] Metal block 35 is made of industrial pure iron DT4C, with a coercivity ≤96A / m and remanence ≤0.003T, exhibiting high permeability and low remanence. When aligned with magnetic block 36, it can quickly respond to changes in the magnetic field, generating a stable adsorption force to assist in locking block 33, while preventing residual magnetism from affecting subsequent operations.

[0028] The magnetic block 36 uses neodymium iron boron permanent magnets with a maximum magnetic energy product ≥40MGOe, remanence Br ≥1.4T, and coercivity Hcj ≥1100kA / m. It is installed perpendicular to the inlet of the slot 34 to ensure no magnetic obstruction during insertion and to generate a strong attraction force after being rotated into place.

[0029] Furthermore, the magnetic block 36 is installed perpendicular to the inlet direction of the slot 34. The metal block 35 inside the card block 33 generates a magnetic attraction with the magnetic block 36 through rotation. The magnetic block 36 is installed perpendicular to the inlet direction of the slot 34, requiring the metal block 35 inside the card block 33 to rotate in order to generate a magnetic attraction with the magnetic block 36. During the insertion of the card block 33 into the slot 34, it is not hindered by magnetic force; however, when the rotating anti-disengagement sleeve 32 rotates the metal block 35 to a specific angle, aligning it with the vertically installed magnetic block 36, a magnetic attraction is generated between them, achieving precise positioning and assisted locking.

[0030] Furthermore, each contact surface between the metal block 35 and the magnetic block 36 is provided with a conductive lubricating layer, which fills the gap between the metal block 35 and the magnetic block 36. This conductive lubricating layer fills the tiny gaps between the metal block 35 and the magnetic block 36. When the metal block 35 and the magnetic block 36 are attracted, the conductive lubricating layer ensures good conductivity of the contact surface, preventing resistance heating due to poor contact. Simultaneously, it reduces the frictional resistance when the metal block 35 and the magnetic block 36 rotate relative to each other, making the rotation and engagement of the locking block 33 smoother and reducing wear on the metal parts.

[0031] It is worth noting that the outer wall of the anti-slip sleeve 32 is provided with anti-slip texture 4, which is evenly distributed along the axial direction of the plug 1. During the insertion and removal operation, the texture structure of the anti-slip texture 4 can significantly increase the friction, providing the user with a stronger grip. Especially in humid environments or when the user is wearing gloves, the anti-slip texture 4 can effectively prevent the anti-slip sleeve 32 from not rotating into place due to slippage, thereby ensuring that the locking block 33 and the locking slot 34 are accurately engaged.

[0032] Specifically, the outer arc surface of the plug 1 is provided with a scale ring 5, and a positioning block 6 is installed on the side wall of the anti-disengagement sleeve 32 corresponding to the scale ring 5. The scale ring 5 and the positioning block 6 installed on the side wall of the anti-disengagement sleeve 32 cooperate with each other. The scale ring 5 is fixed to the outer arc surface of the plug 1 and is marked with angle scale; the positioning block 6 is installed on the side wall of the anti-disengagement sleeve 32 to indicate the rotation position. When the anti-disengagement sleeve 32 is rotated, the positioning block 6 will rotate with the anti-disengagement sleeve 32. When the positioning block 6 is aligned with 90° on the scale ring 5, it means that the metal block 35 in the locking block 33 has accurately matched with the magnetic attraction block 36 in the middle of the slot 34, generating magnetic attraction. This visual method helps the user to judge whether the connection status is in place.

[0033] More specifically, the surface of the scale ring 5 is evenly marked with angle graduations along the circumference, and the protruding end of the positioning block 6 is set with corresponding angle graduations. During operation, by observing the alignment of the protruding end of the positioning block 6 with the graduations of the scale ring 5, the user can intuitively and accurately confirm the rotation angle of the anti-disengagement sleeve 32, and thus determine whether the locking block 33 has rotated into place, effectively avoiding the problem of loose connection caused by insufficient angle, and greatly improving the accuracy of operation and the reliability of connection.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
