[0046] In addition, in the present invention, descriptions such as "first" and "second" are for descriptive purposes only and should not be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0047] The present invention provides a connector 100. It is understood that the connector 100 is applied to an electric vehicle. The power supply component of the electric vehicle is connected to the connecting plug 2 of the connector 100 via a terminal or cable, so that the electric vehicle is connected to an external charging device through the socket 1 of the connector 100 to charge the electric vehicle.

[0048] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9 As shown, in an embodiment of the present invention, the connector 100 includes a socket 1, a plug 2 and a locking structure, wherein the socket 1 is provided with a connecting groove 11; the plug 2 is provided with a connecting end 21; the locking structure includes a locking body 3 and a protective cover 4 movably covered on the locking body 3, and the locking body 3 is used to lock or release the socket 1 and the plug 2 when the connecting end 21 is inserted into the connecting groove 11.

[0049] In this embodiment, connector 100 is installed in an electric vehicle, machine tool, or other equipment. Plug 2 of connector 100 is connected to a power supply unit of the electric vehicle, machine tool, or other equipment, and socket 1 is connected to an external charging device. To prevent socket 1 of connector 100 from being damaged and unable to be replaced, resulting in the entire connector 100 being scrapped, socket 1 and plug 2 of connector 100 utilize a detachable connection method, such as a snap-fit ​​connection, plug-fit connection, screw connection, pin connection, or threaded connection, which is not limited here.

[0050] As will be appreciated, to facilitate the detachability of the receptacle 1 and plug 2 of the connector 100 and simplify the structure, the receptacle 1 is provided with a connection slot 11, and the plug 2 is provided with a connection end 21, which is inserted into the connection slot 11 of the receptacle 1. To improve the reliability of the connection between the receptacle 1 and plug 2 of the connector 100, the connector 100 is also provided with a locking structure, which facilitates the locking body 3 of the locking structure to lock or release the receptacle 1 and plug 2.

[0051] In order to avoid accidental contact with the locking body 3 during use, which may cause the locking body 3 to release the socket 1 and the plug 2, thereby causing the socket 1 and the plug 2 to separate or be poorly connected, in this embodiment, the locking structure also includes a protective cover 4. By movably covering the protective cover 4 on the locking body 3, the locking body 3 is protected to avoid accidental contact that may cause separation or poor connection between the socket 1 and the plug 2.

[0052] The connector 100 of the present invention provides a connection slot 11 on the socket 1 and a connection end 21 on the plug 2. The connection end 21 is inserted into the connection slot 11, and the locking structure's locking body 3 is used to lock or release the socket 1 and plug 2. The protective cover 4 is movably provided on the locking body 3, so that the protective cover 4 protects the locking body 3, thereby effectively preventing accidental contact with the locking body 3 of the connector 100, thereby preventing the locking body 3 from causing poor connection or separation between the socket 1 and plug 2 due to accidental contact. The connector 100 proposed by the present invention not only facilitates unlocking and reliably prevents accidental contact, but also optimizes the shielding effect of the connector.

[0053] In one embodiment, if Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9 As shown, one end of the protective cover 4 is rotatably connected to the socket 1. As can be understood, the rotatable connection between the protective cover 4 and the socket 1 prevents the protective cover 4 from being separated from the connector 100, thereby preventing loss or installation difficulties. On the other hand, the rotation of the protective cover 4 relative to the socket 1 facilitates the cover to be covered on the locking body 3, thereby improving operational convenience.

[0054] In one embodiment, if Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9 As shown, the locking body 3 includes a buckle 31 and a locking assembly 32, wherein the buckle 31 is protruded from the outer wall of the socket 1 adjacent to the connection groove 11; the locking assembly 32 is rotatably arranged on the outer wall of the plug 2 adjacent to the connection end 21, and the locking assembly 32 is provided with a card hole 3211 adapted to the buckle 31.

[0055] It is understandable that the connection mode of the buckle 31 and the lock assembly 32 can be a buckle connection, plug-in fit, screw connection or pin connection, etc. In order to improve the convenience of disassembly and assembly of the socket 1 and the plug 2, the buckle 31 and the lock assembly 32 can be optionally a buckle connection.

[0056] In this embodiment, one of the latch 31 and the locking assembly 32 is provided on the socket 1, and the other is provided on the plug 2. Thus, when the socket 1 and the plug 2 are connected, the connecting end 21 of the plug 2 is inserted into the connecting groove 11 of the socket 1 to realize the conduction of the connector 100, and the latch hole 3211 of the locking assembly 32 is engaged with the latch 31, thereby realizing the locking of the socket 1 and the plug 2.

[0057] like Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8 As shown, a latch 31 is protruded from the outer wall of the socket 1 adjacent to the connection slot 11, and the locking assembly 32 is rotatably connected to the outer wall of the plug 2 adjacent to the connection end 21, so that the latch 31 is engaged in or disengaged from the latch hole 3211 by utilizing the relative rotation of the locking assembly 32 and the plug 2, thereby achieving locking or release.

[0058] Of course, in other embodiments, the buckle 31 may also be provided on the plug 2 , and the locking assembly 32 is rotatably connected to the outer wall of the socket 1 . In this case, one end of the protective cover 4 is rotatably connected to the plug 2 .

[0059] It can be understood that the connecting end 21 of the plug 2 is inserted into the connecting groove 11 of the socket 1, and the socket 1 is detachably connected to the plug 2 through the snap fit between the card hole 3211 of the lock assembly 32 and the card buckle 31, and the protective cover 4 rotates relative to the socket 1 to cover the card buckle 31 and the lock assembly 32, thereby protecting the card buckle 31 and the lock assembly 32, and avoiding accidental contact with the card buckle 31 and the lock assembly 32 during the use of the connector 100, thereby causing the card buckle 31 to disengage from the card hole 3211 of the lock assembly 32, thereby releasing the plug 2 and the socket 1, causing the plug 2 and the socket 1 to separate or have poor connection.

[0060] In one embodiment, if Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9As shown, the protective cover 4 includes a cover body 41 and two rotating arms 42 provided at one end of the cover body 41. The two rotating arms 42 are arranged in parallel. A first axial hole 421 is provided at one end of each rotating arm 42 away from the cover body 41. Two fixing plates 12 are protruded from the outer wall of the socket 1 adjacent to the connecting groove 11. The two fixing plates 12 are arranged opposite to each other and are located on opposite sides of the buckle 31. Each fixing plate 12 is provided with a first rotating hole 13. The two rotating arms 42 are rotatably connected to the two fixing plates 12 through the first rotating hole 13 and the first axial hole 421 via the first rotating shaft 43.

[0061] In this embodiment, the two rotating arms 42 rotate relative to the two fixing plates 12 so that the cover body 41 covers the buckle 31 and the locking assembly 32 .

[0062] It is understood that the cover 41 can be a shell structure, a housing structure, or a plate-like structure. The cover 41 is used to cover the buckle 31 and the lock assembly 32 to prevent the buckle 31 and the lock assembly 32 from being accidentally touched. The rotating arm 42 is used to achieve the rotational connection of the protective cover 4. In this embodiment, to facilitate the rotational connection between the protective cover 4 and the socket 1, the socket 1 is provided with two fixed plates 12 on opposite sides of the buckle 31. The fixed plates 12 are used to install and support the protective cover 4, thereby preventing the protective cover 4 from interfering with the assembly of the buckle 31 and the lock assembly 32, thereby affecting assembly efficiency.

[0063] In this embodiment, there are many ways to rotatably connect the rotating arm 42 of the protective cover 4 to the fixed plate 12. As long as the structure can achieve the rotatable connection, it can be used without limitation.

[0064] In one embodiment, if Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9 As shown, the cover body 41 is provided with locking presser feet 411 protrudingly adjacent to the two rotating arms 42 .

[0065] In this embodiment, the buckle 31 is engaged with the locking hole 3211, and when the cover body 41 covers the buckle 31 and the locking assembly 32, the locking pressure foot 411 is directly opposite to the locking hole 3211. It can be understood that by providing the locking pressure foot 411, the protective cover 4 uses the locking pressure foot 411 to achieve a locking and limiting effect on the locking assembly 32.

[0066] In this embodiment, the card hole 3211 of the locking assembly 32 and the card buckle 31 are the first level of card connection, and the locking pressure foot 411 and the card hole 3211 of the locking assembly 32 are the second level of card connection, thereby ensuring that when the protective cover 4 is covered on the locking body 1, the socket 1 and the plug 2 are firmly connected through the card hole 3211 of the locking assembly 32 and the card buckle 31.

[0067] In one embodiment, if Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9 As shown, the protective cover 4 further includes a stop edge 44 provided at one end of the cover body 41 away from the two rotating arms 42 . The stop edge 44 is provided at an angle to the cover body 41 and extends in a direction away from the socket 1 .

[0068] It can be understood that the blocking edge 44 is set to be tilted. The blocking edge 44 effectively prevents people or foreign objects from touching the lock assembly 32, and also facilitates the user's fingers to enter when unlocking the lock assembly 32, thereby facilitating the opening of the lock assembly 32.

[0069] In one embodiment, if Figure 1 、 Figure 3 and Figure 9 As shown, two opposite sides of the cover body 41 are bent to form two oppositely arranged wings 412, and the cover body 41 is provided with a limit plate 414 corresponding to each wing 412, and a protrusion 413 is provided on the side of each wing 412 facing the limit plate 414. Two mounting plates 22 are protruded from the outer wall of the plug 2 adjacent to the connecting end 21. The two mounting plates 22 are arranged opposite to each other and are located on opposite sides of the locking assembly 32.

[0070] In this embodiment, when the cover body 41 covers the locking assembly 32 , each mounting plate 22 is limited between a wing 412 and a limiting plate 414 and abuts against the protrusion 413 .

[0071] It can be understood that by bending the fins 412 on opposite sides of the cover body 41, the cover body 41 and the two fins 412 cooperate to form a protective cavity. When the cover body 41 covers the buckle 31 and the lock assembly 32, the buckle 31 and the lock assembly 32 are located in the protective cavity, which effectively avoids accidental collision and also prevents other animals or debris from falling between the cover body 41 and the lock assembly 32, thereby causing accidental collision.

[0072] In this embodiment, a limiting plate 414 is provided so that the extension direction of the limiting plate 414 is the same as the extension direction of the wing 412, thereby forming a limiting cavity between the limiting plate 414 and the wing 412. When the cover body 41 covers the locking assembly 32, the mounting plate 22 is limited in the limiting cavity, that is, the mounting plate 22 is limited between the wing 412 and the limiting plate 414.

[0073] It can be understood that by protruding a protrusion 413 on the side of the wing 412 facing the limiting plate 414, the protrusion 413 is used to further limit the mounting plate 22, so that when the protective cover 4 is closed, the user needs to apply a certain force to open the protective cover 4, thereby further playing the role of the protective cover 4 in protecting the locking body 3.

[0074] In this embodiment, the protective cover 4 is provided with the wing 412 and the protrusion 413, which not only ensures that the protective cover 4 is smoothly opened and closed, but also embraces the outer side of the mounting plate 22 when locked, thereby adding a shielding connection channel.

[0075] In one embodiment, if Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8 As shown, each mounting plate 22 has a second rotating hole 23 adjacent to the connecting end 21 , and the locking assembly 32 has a second axial hole 3212 . The locking assembly 32 is rotatably connected to the two mounting plates 22 via a second rotating shaft 324 passing through the second rotating hole 23 and the second axial hole 3212 .

[0076] As will be appreciated, there are various ways to achieve a rotational connection between the latch assembly 32 and the plug 2, and any structure capable of achieving such a rotational connection is acceptable, and this is not a limitation. By configuring the latch assembly 32 and the plug 2 in a rotational connection, the relative rotation of the latch assembly 32 and the plug 2 causes the latch 31 to engage with or disengage from the latch hole 3211, thereby achieving locking or release.

[0077] In one embodiment, if Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8 As shown, the lock assembly 32 includes a lock 321, a lock cap 322 and a spring 323, wherein the lock 321 is rotatably connected to the plug 2, a locking hole 3211 is provided at one end of the lock 321 adjacent to the connection end 21, and a mounting groove 3213 is provided at the end of the lock 321 away from the locking hole 3211; the lock cap 322 is slidably mounted on the outer wall of the mounting groove 3213; the spring 323 is arranged in the mounting groove 3213, and the two ends of the spring 323 are respectively connected to the bottom wall of the mounting groove 3213 and the lock cap 322.

[0078] It can be understood that by providing the lock cap 322, the lock cap 322 slides relative to the lock catch 321, thereby utilizing the lock cap 322 to achieve rotation of the lock catch 321 relative to the plug 2. In this embodiment, a sliding groove is provided on the side of the lock cap 322 facing the lock catch 321, so that the end of the lock catch 321 provided with the mounting groove 3213 extends into the sliding groove. By providing an increasing or decreasing slide on the groove wall of the sliding groove, when the lock cap 322 slides relative to the lock catch 321, the slide exerts a downward or upward force on the lock catch 321, thereby enabling the lock catch 321 to rotate about the second rotation axis 324, so that the end of the lock catch 321 provided with the locking hole 3211 engages with or disengages from the buckle 31.

[0079] In this embodiment, by arranging a spring 323 between the lock buckle 321 and the lock cap 322, the spring 323 can be used to realize compression and reset functions. When the user pushes the lock cap 322 to slide relative to the lock buckle 321, the lock cap 322 squeezes the spring 323 to make the lock buckle 321 rotate around the second rotation axis 324, so that the locking hole 3211 is disengaged from the buckle 31, thereby releasing the plug 2 and the socket 1; when the user releases, the spring 323 resets and pushes the lock cap 322 to slide relative to the lock buckle 321, so that the lock buckle 321 rotates around the second rotation axis 324, so that the locking hole 3211 is engaged with the buckle 31 to lock the plug 2 and the socket 1, or the locking hole 3211 is away from the buckle 31.

[0080] In one embodiment, if Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8 As shown, the locking assembly 32 further includes a locking spring 325 , which elastically abuts against the locking catch 321 and the outer wall of the plug 2 .

[0081] It can be understood that the locking spring 325 is sleeved on the second rotating shaft 324 and is located between the lock buckle 321 and the outer wall of the plug 2, so that the two ends of the locking spring 325 elastically abut against the lock buckle 321 and the outer wall of the plug 2, thereby utilizing the compression and reset of the locking spring 325 to always keep the locking hole 3211 and the buckle 31 engaged when the locking hole 3211 of the lock buckle 321 is engaged with the buckle 31.

[0082] In one embodiment, if Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8 As shown, a boss 3214 is further provided on one end of the lock buckle 321 away from the installation slot 3213 , and the boss 3214 is located on a side of the locking hole 3211 away from the installation slot 3213 .

[0083] It can be understood that by protruding the boss 3214 on the lock buckle 321, the boss 3214 can be used to cooperate with the locking pressure foot 411 of the protective cover 4, thereby effectively preventing the locking hole 3211 of the lock buckle 321 from being separated from the buckle 31.

[0084] In one embodiment, if Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8 As shown, a limiting platform 24 is protruded from the outer wall of the plug 2 adjacent to the connecting end 21 . When the buckle 31 is engaged with the locking hole 3211 , the lock buckle 321 abuts against the limiting platform 24 .

[0085] It can be understood that by setting the limit platform 24, the two ends of the limit platform 24 are connected to the two mounting plates 22 and are located adjacent to the connecting end 21, so that the limit platform 24 can be used to limit and support the lock 321. In this way, when the connecting end 21 of the plug 2 is inserted into the connecting groove 11 of the socket 1, the lock 321 will not interfere with the socket 1.

[0086] The present invention further provides an electric vehicle comprising a vehicle body and a connector 100 disposed thereon. The specific structure of connector 100 is similar to that of the aforementioned embodiments. Since this electric vehicle utilizes all of the technical solutions of all of the aforementioned embodiments, it possesses at least all of the beneficial effects brought about by the technical solutions of the aforementioned embodiments, and therefore will not be further elaborated upon here.

[0087] The connector 100 proposed by the present invention, through structural optimization, reduces the possibility of accidental or unintentional contact with the locking body 3, which could cause the locking hole 3211 of the lock catch 321 of the locking body 3 to disengage from the lock catch 31 and unlock, leading to a disconnection between the plug 2 and the socket 1 or a momentary interruption of the shield. By forming fins 412 on both sides of the cover body 41 of the protective cover 4, the fins 412 are used to prevent accidental contact while enhancing the shielding effect of the connector. By providing locking pressure feet 411 on the cover body 41, the locking pressure feet 411 are used to limit the closing position when the locking hole 3211 of the lock catch 321 is engaged with the lock catch 31. By providing a protrusion 413 on the fins 412, it is possible to effectively prevent the machine tool or electric vehicle from disengaging due to vibration during operation. The protective cover 4 of the present invention increases the shielding reliability of the connector 100. The connector 100 of the present invention not only achieves convenient unlocking operation and reliable anti-accidental contact locking, but also optimizes the shielding effect of the connector 100.

[0088] The above descriptions are merely optional embodiments of the present invention and do not limit the patent scope of the present invention. All equivalent structural transformations made based on the contents of the present invention's description and drawings, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present invention.
