Figure 3 2 is a schematic diagram of the wrench 2100 provided in the embodiment of the present application rotating relative to the plug assembly 2200 to the second position. Figure 2 and Figure 3 As shown, for the convenience of description, the direction in which the connector plug 2000 shown in each figure is away from the connector socket 3000 is defined as "high" or "top", and the direction in which the connector plug 2000 is close to the connector socket 3000 is defined as "low" or "bottom".

[0076] In some embodiments, the connector plug 2000 includes a plug assembly 2200 and a wrench 2100. The plug assembly 2200 is used to connect to the connector socket 3000. The wrench 2100 is connected to the plug assembly 2200 and can rotate relative to the plug assembly 2200. When the wrench 2100 rotates to a first position relative to the plug assembly 2200, the plug assembly 2200 and the connector socket 3000 are detachably connected. When the wrench 2100 rotates to a second position relative to the plug assembly 2200, the plug assembly 2200 and the connector socket 3000 are locked. Figure 1 The overall structure of the connector plug 2000 includes a plug assembly 2200 and a wrench 2100. The wrench 2100 is connected to the plug assembly 2200 and can rotate relative to the plug assembly 2200. The wrench 2100 is a metal or plastic plate with high strength and toughness, which is convenient for applying force to make it rotate. The plastic process of the metal or plastic plate is simple and the production cost is low. After the connector plug 2000 is connected to the connector socket 3000, Figure 2 and Figure 3 As shown, when the wrench 2100 rotates in the opposite direction relative to the plug assembly 2200 (as shown in FIG. Figure 3 direction of rotation) to a first position (as shown Figure 2 3000), the plug assembly 2200 and the connector socket 3000 are detachably connected, that is, the plug assembly 2200 and the connector socket 3000 are in an unlocked state, at which time the plug assembly 2200 can be detached from or plugged into the connector socket 3000; when the wrench 2100 rotates forward relative to the plug assembly 2200 (as shown in the figure), the plug assembly 2200 and the connector socket 3000 are detachably connected, that is, the plug assembly 2200 and the connector socket 3000 are in an unlocked state, at which time the plug assembly 2200 can be detached from or plugged into the connector socket 3000; Figure 2 direction of rotation) to a second position (as shown Figure 3 When the plug assembly 2200 is in the position shown in the figure, the plug assembly 2200 is locked with the connector socket 3000. At this time, the plug assembly 2200 is plugged into the connector socket 3000 and cannot be detached. Thus, the connection between the plug assembly 2200 and the connector socket 3000 can be locked by the wrench 2100 to prevent the connector plug 2000 and the connector socket 3000 from being loosened, thereby ensuring the stability of the charging performance and improving the user experience.

[0077] In some embodiments, the wrench 2100 is provided with a slide groove 2140 extending along the rotation direction of the wrench 2100, which is used to cooperate with the corresponding component on the connector socket 3000; when the wrench 2100 is in the first position, the first slide groove position 2141 of the slide groove 2140 cooperates with the corresponding component on the connector socket 3000, so that the plug assembly 2200 and the connector socket 3000 are detachably connected; when the wrench 2100 is in the second position, the second slide groove position 2142 of the slide groove 2140 cooperates with the corresponding component on the connector socket 3000, so that the plug assembly 2200 and the connector socket 3000 are locked. Figure 2 and Figure 3 As shown, in this embodiment, the wrench 2100 is provided with a quarter-circular arc-shaped slide groove 2140 extending along the rotation direction of the wrench 2100, and the two ends of the slide groove 2140 are provided with a first slide groove position 2141 and a second slide groove position 2142; the corresponding component on the connector socket 3000 is a protrusion 3100, and the slide groove 2140 is sleeved and slid outside the protrusion 3100, so that the rotation movement of the wrench 2100 relative to the plug assembly 2200 can drive the plug assembly 2200 to be plugged and locked to the connector socket 3000. Specifically, when the wrench 2100 is in the first position (such as Figure 2 3100, the plug assembly 2200 and the connector socket 3000 are in a detachable connection (unlocked) state, and the plug assembly 2200 can be plugged into or out of the connector socket 3000; when the wrench 2100 is in the second position (as shown in the figure), the first slot position 2141 of the slot 2140 cooperates with the protrusion 3100, and the plug assembly 2200 and the connector socket 3000 are in a detachable connection (unlocked) state, and the plug assembly 2200 can be plugged into or out of the connector socket 3000; Figure 3 When the plug assembly 2200 and the connector socket 3000 are in the locked state, the plug assembly 2200 is plugged into the connector socket 3000 and cannot be disengaged. In other embodiments, the slide groove 2140 on the wrench 2100 may also be other irregular curves or straight lines, the first slide groove position 2141 and the second slide groove position 2142 may also be set at the middle position of the slide groove 2140, and the first slide groove position 2141 and the second slide groove position 2142 may also be provided with a fixing groove or a fixing ring to fix the boss 3100, so as to further enhance the plugging stability.

[0078] In this embodiment, the slide groove 2140 also penetrates two opposite surfaces of the wrench 2100 to be sleeved on the boss 3100 and reduce the friction when the slide groove 2140 slides, thereby improving the smoothness of the rotation of the wrench 2100.

[0079] See also Figures 2 to 4 , Figure 4 : is a schematic diagram of the structure of the wrench 2100 provided in an embodiment of the present application. In some embodiments, along the connection direction between the plug assembly 2200 and the connector socket 3000, the slide groove 2140 is connected to the outside at the first slide groove position 2141 to form a notch 2143; when the corresponding component of the connector socket 3000 is located at the first slide groove position 2141 of the slide groove 2140, along the connection direction between the plug assembly 2200 and the connector socket 3000, the corresponding component of the connector socket 3000 and the slide groove 2140 can move relative to each other; when the corresponding component in the connector socket 3000 is located at the second slide groove position 2142 of the slide groove 2140, along the connection direction between the plug assembly 2200 and the connector socket 3000, the corresponding component in the connector socket 3000 and the slide groove 2140 cannot move relative to each other. Figure 4As shown, the slide groove 2140 on the wrench 2100 is connected to the outside at the first slide groove position 2141 to form a gap 2143, and the slide groove 2140 on the wrench 2100 has no gap 2143 at the second slide groove position 2142. Figure 2 As shown, when the wrench 2100 is connected to the plug assembly 2200 and the wrench 2100 is in the first position, the notch 2143 connects the slide groove 2140 with the outside along the connection direction of the plug assembly 2200 and the connector socket 3000, and the slide groove 2140 can be inserted into or separated from the protrusion 3100 along the notch 2143 from the first slide groove position 2141, so that the plug assembly 2200 can be inserted into or separated from the connector socket 3000 along the connection direction of the plug assembly 2200 and the connector socket 3000, thereby unlocking the plug assembly 2200 and the connector socket 3000. Figure 3 As shown, when the wrench 2100 is connected to the plug assembly 2200 and the wrench 2100 is in the second position, the second slide position 2142 of the slide 2140 is engaged with the outside of the boss 3100, so that the plug assembly 2200 cannot be plugged into or detached from the connector socket 3000 along the connection direction between the plug assembly 2200 and the connector socket 3000, thereby locking the plug assembly 2200 and the connector socket 3000.

[0080] See also Figures 2 to 5 , Figure 5 2 is a schematic diagram of the structure of the plug assembly 2200 provided in an embodiment of the present application. In some embodiments, a wrench mounting post 2230 is provided on the outer wall of the plug assembly 2200, and the wrench 2100 includes a wrench arm 2110, and a wrench mounting hole 2130 is correspondingly provided on the wrench arm 2110, and the wrench mounting hole 2130 is sleeved on the wrench mounting post 2230, so that the wrench 2100 can rotate relative to the plug assembly 2200. The wrench mounting hole 2130 and the wrench mounting post 2230 are clearance-matched. In other embodiments, a wrench mounting hole 2130 may also be provided on the outer wall of the plug assembly 2200, and a wrench mounting post 2230 is provided on the wrench arm 2110 of the wrench 2100, and the wrench mounting post 2230 is inserted into the wrench mounting hole 2130 and can rotate, so that the wrench 2100 can rotate relative to the plug assembly 2200 with the wrench mounting post 2230 as the rotation axis.

[0081] In this embodiment, a plurality of material removal holes 2150 of different shapes are further provided on the wrench arm 2110, so as to reduce shrinkage and deformation and other undesirable problems as much as possible while meeting the strength requirements, save materials and improve the lightweight of the product.

[0082] In some embodiments, a boss 2240 is provided at a position of the outer wall of the plug assembly 2200 corresponding to the wrench mounting column 2230, the wrench mounting column 2230 is provided on a side of the boss 2240 away from the outer wall of the plug assembly 2200, and the portion of the wrench arm 2110 abutting against the plug assembly 2200 abuts against the boss 2240. That is, the wrench arm 2110 does not directly abut against the outer wall of the plug assembly 2200, but abuts against the boss 2240, thereby reducing the contact area between the wrench arm 2110 and the plug assembly 2200, reducing the friction force when the wrench arm 2110 rotates, and improving the smoothness of the rotation of the wrench 2100.

[0083] In some embodiments, a rotation limit point 2250 is provided on the outer wall of the plug assembly 2200, and a rotation limit portion 2160 is provided on the wrench arm 2110. The rotation limit portion 2160 cooperates with the rotation limit point 2250 to limit the rotational motion range of the wrench 2100 relative to the plug assembly 2200. In this embodiment, a first rotation limit groove 2251 and a second rotation limit column 2252 are provided on the outer wall of the plug assembly 2200, and correspondingly, a first rotation limit platform 2161 and a second rotation limit surface 2162 are provided on the wrench arm 2110. The first rotation limit platform 2161 is provided on the surface where the wrench arm 2110 abuts against the boss 2240, and the second rotation limit surface 2162 is a bottom surface of the wrench arm 2110. When the wrench 2100 is in the first position, the first rotation limit platform 2161 of the wrench arm 2110 is clamped in the first rotation limit groove 2251, limiting the wrench 2100 from further reverse rotation; when the wrench 2100 is in the second position, the second rotation limit surface 2162 of the wrench arm 2110 abuts against the top surface of the second rotation limit column 2252, limiting the wrench 2100 from further forward rotation; thereby ensuring that the plug assembly 2200 and the connector socket 3000 are plugged in place, and preventing the wrench 2100 from excessive rotation and damaging other components. In other embodiments, the cooperation form of the rotation limit point 2250 and the rotation limit part 2160 can also be set to a card point and a card slot sliding cooperation limit, a baffle rotating against a baffle column limit, etc.

[0084] In some embodiments, the wrench 2100 includes two wrench arms 2110 and a connecting arm 2120, and the ends of the two wrench arms 2110 away from the connector socket 3000 are connected by the connecting arm 2120; an external position is provided on the outer wall of the plug assembly 2200, and when the plug assembly 2200 and the connector socket 3000 are plugged in, the connecting arm 2120 overlaps the external position. In this embodiment, a connecting arm 2120 connects two wrench arms 2110 to form a wrench 2100 with a "J"-shaped structure. Each wrench arm 2110 is provided with a wrench mounting hole 2130, and correspondingly, two opposite outer walls of the plug assembly 2200 are provided with a wrench mounting column 2230. The wrench mounting holes 2130 are correspondingly sleeved on the wrench mounting columns 2230. Each of the two wrench arms 2110 is provided with a slide groove 2140, and two opposite outer walls of the connector socket 3000 are correspondingly provided with a convex column 3100. The slide grooves 2140 are correspondingly sleeved and slid outside the convex column 3100, so that the connector 1000 assembly and the connector socket 3000 are clamped between the two wrench arms 2110. When the wrench 2100 is rotated, the two wrench arms 2110 can be simultaneously stressed and evenly act on both ends of the connector socket 3000, making the unlocking and locking operations of the connector socket 3000 and the plug assembly 2200 smoother, further improving the durability of the product. In other embodiments, a single-sided wrench 2100 structure with a single wrench arm 2110 can also be used.

[0085] In this embodiment, the plug assembly 2200 includes a first end 2210 and a second end 2220, wherein the first end 2210 is used to plug into the connector socket 3000, and the second end 2220 is used to overlap the connecting arm 2120. The bottom surface of the first end 2210 is higher than the bottom surface of the second end 2220, so as to form a certain reserved space to accommodate the connector socket 3000. The top surface of the second end 2220 is lower than the top surface of the first end 2210, so as to form an externally positioned overlapping connecting arm 2120. When the plug assembly 2200 is locked with the connector socket 3000, the connecting arm 2120 overlaps the top surface of the second end 2220 and is flush with the top surface of the first end 2210, so that the overall appearance of the connector plug 2000 is more regular and beautiful, and the connecting arm 2120 of the wrench 2100 is prevented from protruding and being scratched, thereby causing the plug assembly 2200 to be unlocked from the connector socket 3000. In other embodiments, the second end 2220 of the plug assembly 2200 may be provided with a groove, a buckle or other structure to serve as an external position.

[0086] See also Figure 3In some embodiments, the connecting arm 2120 is provided with a first locking portion 2170, and the plug assembly 2200 is provided with a second locking portion 2260. When the plug assembly 2200 is locked with the connector socket 3000, the first locking portion 2170 is engaged with the second locking portion 2260 to further fix the connecting arm 2120 on the plug assembly 2200, and prevent the wrench 2100 from rotating due to the scratch of the connecting arm 2120, resulting in the unlocking of the connector socket 3000 and the plug assembly 2200. The first locking portion 2170 is engaged with the second locking portion 2260 by hook interlocking, buckle interlocking, slot interlocking, etc.

[0087] See also Figure 6 , Figure 6 2 is a schematic diagram of the structure of the first locking portion 2170 of the wrench 2100 provided in an embodiment of the present application.

The plug assembly 2200 includes a plug rubber core 4000, a stamped terminal 5000, a rubber plug 6000 and a rubber package 7000; the plug rubber core 4000 includes a head 4100 and a tail 4200, the head 4100 is used to plug the connector socket 3000, and the tail 4200 is rubber-coated to form the rubber package 7000; the terminal 5000 is a hollow column, and the rubber plug 6000 is filled in the terminal 5000 from the tail 4200 to the head 4100 to close the opening of the terminal 5000 near the tail 4200, and the terminal 5000 filled with the rubber plug 6000 is installed in the plug rubber core 4000. Among them, the terminal 5000 adopts a hollow columnar stamping terminal 5000, which has a lower cost than the traditional machined terminal 5000. Since it has a through hole 7100 structure inside, during the encapsulation process, the encapsulation material will flow from the tail 4200 through the internal through hole 7100 of the terminal 5000, and finally enter the plug-in part of the terminal 5000 to cool and form, so that the terminal 5000 is deformed, resulting in the plug assembly 2200 and the connector socket 3000 cannot be plugged in. Therefore, in this embodiment, a rubber plug 6000 is used to close the opening of the terminal 5000 near the tail 4200. The specific manufacturing steps of the plug assembly 2200 are: fill the rubber plug 6000 into the terminal 5000 from the tail 4200 to the head 4100, then install the single-side sealed terminal 5000 filled with the rubber plug 6000 into the plug rubber core 4000, and finally perform rubber encapsulation on the tail 4200 of the plug rubber core 4000 equipped with the rubber plug 6000 and the terminal 5000 to form an encapsulated body 7000.
