[0013] Optionally, the elastic locking portion includes a first elastic locking buckle connected to the first elastic triggering piece and a second elastic locking buckle connected to the second elastic triggering piece;

[0014] The buckle includes a first buckle head and a second buckle head symmetrically arranged on opposite sides of the plug; when the first elastic lock buckle is clamped on the first buckle head and the second elastic lock buckle is clamped on the second buckle head, the handle is clamped on the plug.

[0022] In the present invention, since the first end of the connector handle can rotate about the rotation axis on the plug, when the handle rotates about the rotation axis in a first direction, the connecting protrusion also slides along the arcuate slot. When the handle rotates until the first engaging portion at the second end engages with the second engaging portion on the plug, the connecting protrusion slides until it abuts against the locking end located in the arcuate slot. At this time, the sliding of the connecting protrusion in the arcuate slot is prevented, and the position of the connecting protrusion is limited to abutting against the locking end and not moving. As a result, the relative motion relationship between the connecting protrusion and the handle becomes static. In this way, the socket for mounting the connecting protrusion and the plug fixedly connected to the handle also become static and do not produce relative motion. In this way, the dynamic cooperation between the handle, the first locking portion, and the second locking portion achieves a secure locking between the plug and the socket while preventing accidental unlocking due to external forces. The above-mentioned locking structure in the present invention no longer relies on a hard interference connection structure, greatly reducing the stringent requirements for dimensional accuracy, while ensuring the stability and reliability of the connector and reducing the manufacturing difficulty. In addition, in the present invention, the plug and the socket can be locked only by rotating the handle, which greatly improves the convenience of using the connector.

[0035] like Figures 1 to 5 As shown, an embodiment of the present invention provides a connector locking structure, comprising:

[0036] A handle 1, wherein a first end of the handle 1 is rotatably mounted on a rotating shaft 8 of a plug 4 of the connector;

[0037] The first locking portion 2 includes a first clamping portion provided at the second end of the handle 1 and a second clamping portion provided on the plug 4; the first end and the second end are provided opposite to each other;

[0038] The second locking portion 3 includes an arcuate slot 32 provided at the first end of the handle 1, and a connecting protrusion 31 provided on the socket 5 of the connector and slidably inserted into the arcuate slot 32; the arcuate slot 32 includes a locking end 321; the arcuate slot 32 is provided around the rotating shaft 8;

[0039] The connecting protrusion 31 is used to abut against the locking end 321 of the arc-shaped slot 32 that rotates with the handle 1 when the handle 1 rotates around the rotating shaft 8 toward the first direction until the first clamping portion and the second clamping portion are clamped, so as to lock the plug 4 and the socket 5. The second end of the handle 1 of the connector is provided with a first locking portion 2, and the first clamping portion provided on the handle 1 in the first locking portion 2 is clamped with the second clamping portion on the plug 4; the first end of the handle 1 of the connector is rotatably mounted on the plug 4 of the connector through the rotating shaft 8, and the first end of the handle 1 is provided with an arc-shaped slot 32, and the socket 5 of the connector is provided with a connecting protrusion 31, and the connecting protrusion 31 is slidably inserted into the arc-shaped slot 32. When the handle 1 rotates around the rotating shaft 8 toward the first direction (the first direction of rotation of the handle 1 can be clockwise or counterclockwise, such as Figure 1When the handle 1 is rotated to the first engaging portion 2 and the second engaging portion 3, the connecting protrusion 31 will slide to abut against the locking end 321. At this time, the plug 4 and the socket 5 are locked, and the sliding of the connecting protrusion 31 in the arcuate slot 32 will be prevented. The position of the connecting protrusion 31 will be limited to abut against the locking end 321 and will not move. Then, the relative movement relationship between the connecting protrusion 31 and the handle 1 will become a static state. In this way, the socket 5 for installing the connecting protrusion 31 and the plug 4 fixedly connected to the handle 1 will also be in a static state without relative movement. In this way, the dynamic cooperation between the handle 1, the first locking portion 2 and the second locking portion 3 can achieve a firm locking between the plug 4 and the socket 5, and prevent accidental unlocking due to external force.

[0040] In the present invention, since the first end of the handle 1 of the connector can rotate around the rotating shaft 8 on the plug 4, when the handle 1 is rotated around the rotating shaft 8 toward the first direction, the connecting protrusion 31 also slides along the arc-shaped slot 32. When the handle 1 is rotated to the second end of the first clamping portion and is clamped with the second clamping portion on the plug 4, the connecting protrusion 31 will slide until it abuts against the locking end 321 located in the arc-shaped slot 32. At this time, the sliding of the connecting protrusion 31 in the arc-shaped slot 32 will be prevented, and the position of the connecting protrusion 31 will be limited to abutting against the locking end 321 and not moving. Then, the relative movement relationship between the connecting protrusion 31 and the handle 1 will become a static state. In this way, the socket 5 for mounting the connecting protrusion 31 and the plug 4 fixedly connected to the handle 1 will also be in a static state without generating relative movement. In this way, the dynamic cooperation between the handle 1, the first locking portion 2 and the second locking portion 3 not only achieves a firm locking between the plug 4 and the socket 5, but also prevents accidental unlocking due to external force. The locking mechanism of the present invention no longer relies on a rigid interference connection, significantly reducing the stringent requirements for dimensional accuracy. This ensures the stability and reliability of the connector while also reducing manufacturing complexity. Furthermore, the present invention only requires turning the handle 1 to lock the plug 4 and receptacle 5, significantly improving the connector's ease of use.

[0041] In one embodiment, if Figures 1 to 3As shown, an unlocking end 322 is further provided on the end of the arc-shaped slide groove 32 away from the locking end 321. The connecting protrusion 31 is also used to disengage from the unlocking end 322 after the handle 1 is continuously rotated about the rotation axis 8 in the second direction, so as to release the lock of the plug 4 and the socket 5. It can be understood that after the engagement between the first clamping portion and the second clamping portion of the first locking portion 2 is released, the handle 1 is rotated about the rotation axis 8 in the second direction (the second direction is opposite to the first direction, and the first direction of rotation of the handle 1 can be clockwise or counterclockwise, as shown in FIG. Figure 1 In the connector locking structure shown in FIG, the second direction is counterclockwise rotation. At this time, the connecting protrusion 31 is still slidably inserted into the arcuate slot 32, but the connecting protrusion 31 will slide along the arcuate slot 32 from the locking end 321 to the unlocking end 322 during the rotation of the handle 1, and then disengage from the unlocking end 322. At this time, the plug 4 and the socket 5 are unlocked, and the socket 5 and the plug 4 can be separated. The structure of the unlocking end 322 can be set according to needs. The unlocking end 322 can be provided with an opening to allow the connecting protrusion 31 to disengage from the arcuate slot 32 at this opening position. This locking structure can complete the unlocking operation by simply rotating the handle 1, and the unlocking process is smooth and simple without any jamming, further improving the convenience of using the connector.

[0042] In one embodiment, if Figures 1 to 5 As shown, the first engaging portion includes an elastic unlocking portion 21 connected to the second end of the handle 1 and an elastic locking portion 22 connected to the elastic unlocking portion 21; the second engaging portion includes a buckle 23 provided on the plug 4; the handle 1 is engaged with the buckle 23 via the elastic locking portion 22. It is understood that when the handle 1 rotates about the rotation axis 8 in the first direction, the elastic locking portion 22 gradually approaches the buckle 23 on the plug 4 as the handle 1 rotates. When the elastic locking portion and the buckle 23 are aligned and engaged, the plug 4 and the socket 5 are locked.

[0043] When unlocking is required, it is only necessary to press the elastic unlocking portion 21. The elastic unlocking portion 21 is squeezed and deformed, so that the engaging state between the elastic locking portion 22 and the buckle 23 is released. At this time, the handle 1 is rotated about the rotating shaft 8 in the second direction (opposite to the first direction). During the rotation of the handle 1, the connecting protrusion 31 will slide along the arc-shaped sliding groove 32 from the locking end 321 to the unlocking end 322 and disengage from the unlocking end 322. In this way, the lock between the plug 4 and the socket 5 is released, and the plug 4 can be easily pulled out of the socket 5.

[0044] In one embodiment, if Figure 1 and Figure 4As shown, the elastic unlocking portion 21 includes a locking rod 213 connected to the second end of the handle 1, and a first elastic triggering piece 211 and a second elastic triggering piece 212, both connected to the elastic locking portion 22. The locking rod 213 is connected between the first elastic triggering piece 211 and the second elastic triggering piece 212. The first elastic triggering piece 211 and the second elastic triggering piece 212 are symmetrically arranged on opposite sides of the plug 4, and are each separated from the sidewall of the plug 4 by a preset pressing gap. It can be understood that the first elastic triggering piece 211 and the second elastic triggering piece 212 are connected to both ends of the locking rod 213 and together constitute the main body of the elastic unlocking portion 21. The first elastic triggering piece 211 and the second elastic triggering piece 212 are not only responsible for transmitting the force of the locking rod 213, but also have a certain degree of elasticity. The first elastic trigger piece 211 and the second elastic trigger piece 212 are separated from the side wall of the plug 4 by a preset pressing gap. The setting of the preset pressing gap ensures that the first elastic trigger piece 211 and the second elastic trigger piece 212 have a certain movable space (clearance) with the side wall of the plug 4, thereby avoiding the occurrence of hard interference and jamming. It also avoids the problem of unsmooth unlocking caused by dimensional deviation of the unlocking structure of the handle 1, thereby improving the stability and reliability of the connector. For example, when the connection to the machine needs to be unlocked, it is only necessary to apply external force (such as manual pressure) to the first elastic trigger piece 211 and the second elastic trigger piece 212 to cause them to elastically deform and compress the preset pressing gap. The deformation drives the lock rod 213 to move, thereby separating the elastic lock portion 22 from the buckle 23, and realizing the unlocking function.

[0045] In one embodiment, if Figure 3 and Figure 4 As shown, the elastic locking portion 22 includes a first elastic locking buckle 221 connected to the first elastic triggering piece 211 and a second elastic locking buckle 222 connected to the second elastic triggering piece 212;

[0046] The buckle 23 includes a first buckle head 231 and a second buckle head 232 symmetrically arranged on opposite sides of the plug 4; when the first elastic lock buckle 221 is clamped on the first buckle head 231 and the second elastic lock buckle 222 is clamped on the second buckle head 232, the handle 1 is clamped with the plug 4. Understandably, the first elastic lock buckle 221 is connected to the first elastic trigger piece 211, the second elastic lock buckle 222 is connected to the second elastic trigger piece 212, the first buckle head 231 of the buckle 23 is arranged opposite to the first buckle head 231, and the second buckle head 232 of the buckle is arranged opposite to the second buckle head 232; when the first elastic lock buckle 221 is fully aligned and snapped into the first buckle head 231, and the second elastic lock buckle 222 is snapped into the second buckle head 232, a firm snap connection can be achieved between the second end of the handle 1 and the plug 4; this structure can avoid locking failure caused by improper operation or dimensional deviation. Since a pressing gap is preset between the first elastic trigger piece 211, the second elastic trigger piece 212 and the side wall of the plug 4, when the handle 1 is manually pressed or rotated, the unlocking action of the elastic lock part 22 and the buckle 23 can be triggered more easily, and the flexibility of the snap connection operation is also improved.

[0047] In one embodiment, if Figure 1 and Figure 4 As shown, the locking structure further includes a third locking portion, which includes a buckle 6 mounted on the locking rod 213 and a slot 7 provided on the plug 4. It can be understood that when the first elastic locking buckle 221 is engaged with the first buckle head 231 and the second elastic locking buckle 222 is engaged with the second buckle head 232, the buckle 6 on the locking rod 213 is inserted into the slot 7 on the plug 4, further enhancing the locking stability between the second end of the handle 1 and the plug 4.

[0048] The present invention further provides a high-voltage connector, comprising a plug 4, a socket 5, and the above-mentioned connector locking structure; the socket 5 is provided with a rotation shaft 8, and the handle 1 is provided with a rotation hole 11 sleeved on the rotation shaft 8. In the connector locking structure of the above-mentioned embodiment of the present invention, the connector locking structure includes a handle 1, a first end of which is rotatably mounted on the rotation shaft 8 of the connector plug 4;

[0049] The first locking portion 2 includes a first clamping portion provided at the second end of the handle 1 and a second clamping portion provided on the plug 4; the first end and the second end are provided opposite to each other;

[0050] The second locking portion 3 includes an arcuate slot 32 provided at the first end of the handle 1, and a connecting protrusion 31 provided on the socket 5 of the connector and slidably inserted into the arcuate slot 32; the arcuate slot 32 includes a locking end 321; the arcuate slot 32 is provided around the rotating shaft 8;

[0051] The connecting protrusion 31 is used to abut against the locking end 321 of the arc-shaped sliding groove 32 that rotates with the handle 1 when the handle 1 rotates in the first direction around the rotating axis 8 until the first clamping portion is clamped with the second clamping portion, so as to lock the plug 4 and the socket 5.

[0052] In the high-voltage connector of the above embodiment of the present invention, since the first end of the handle 1 of the connector can rotate about the rotation axis 8 on the plug 4, when the handle 1 rotates about the rotation axis 8 in the first direction, the connecting protrusion 31 also slides along the arc-shaped slot 32. When the handle 1 rotates to the second end of the first engaging portion and engages with the second engaging portion on the plug 4, the connecting protrusion 31 will slide until it abuts against the locking end 321 located in the arc-shaped slot 32. At this time, the sliding of the connecting protrusion 31 in the arc-shaped slot 32 will be prevented, and the position of the connecting protrusion 31 will be limited to abutting against the locking end 321 and not moving. Then, the relative motion relationship between the connecting protrusion 31 and the handle 1 will become a static state. In this way, the socket 5 for mounting the connecting protrusion 31 and the plug 4 fixedly connected to the handle 1 will also be in a static state without generating relative motion. In this way, the dynamic cooperation between the handle 1, the first locking portion 2 and the second locking portion 3 not only achieves a firm locking between the plug 4 and the socket 5, but also prevents accidental unlocking due to external force. The locking mechanism of the present invention no longer relies on a rigid interference connection, significantly reducing the stringent requirements for dimensional accuracy. This ensures the stability and reliability of the connector while also reducing manufacturing complexity. Furthermore, the present invention only requires turning the handle 1 to lock the plug 4 and receptacle 5, significantly improving the connector's ease of use.

[0053] In one embodiment, if Figure 1 and Figure 5As shown, the plug 4 is provided with a strip groove 41, and the socket 5 is provided with a slide rail 51. The slide rail 51 is slidably mounted in the strip groove 41. The connecting protrusion 31 is mounted on the slide rail 51, and the connecting protrusion 31 passes through the strip groove 41 and is inserted into the arcuate slide groove 32. It can be understood that the connecting protrusion 31 passes through the strip groove 41 and is inserted into the arcuate slide groove 32. When the plug 4 is pushed toward the socket 5 (the socket 5 is inserted into the plug 4), the slide rail 51 slides along the strip groove 41, and the connecting protrusion 31 gradually penetrates along the guide path of the arcuate slide groove 32 until it reaches the locking end 321. At this time, the socket 5 for mounting the connecting protrusion 31 and the plug 4 fixedly connected to the handle 1 will also be in a stationary state without relative movement, thereby forming a stable electrical connection between the plug 4 and the socket 5. On the contrary, when it is necessary to separate the plug 4 and the socket 5, it is only necessary to apply a reverse force to make the slide rail 51 slide in the opposite direction, and the connecting protrusion 31 will gradually withdraw along the trajectory of the arc-shaped slide groove 32 until the connecting protrusion 31 slides from the locking end 321 to the unlocking end 322 and disengages from the plug 4, thereby achieving convenient separation.

[0054] In one embodiment, if Figure 1 and Figure 4 As shown, the plug 4 is provided with a slot 42, and the socket 5 includes an insertion bar 52, through which the socket 5 is inserted into the slot 42. It is understood that during the process of plugging, locking, and separating the plug 4 and the socket 5, the insertion bar 52 is smoothly inserted or removed along the guide direction of the slot 42. Specifically, when the insertion bar 52 of the socket 5 is aligned and pushed into the slot 42 of the plug 4 until it reaches the predetermined locking position, the contact surface between the insertion bar 52 and the slot 42 is tightly fitted, forming a stable connection between the plug 4 and the socket 5. To separate the plug 4 and the socket 5, simply apply an appropriate counterforce to smoothly remove the insertion bar 52 along the guide direction of the slot 42.

[0055] In one embodiment, if Figure 1 and Figure 4As shown, the socket 5 includes a first power terminal 43 connected to the insert 52 and a copper busbar 9 connected to the first power terminal 43. The plug 4 includes a cable 10, a conductor portion (not shown), a plug body (not shown), and a second power terminal (not shown). The insert 42, the conductor portion, and the second power terminal are all located on the plug body; the conductor portion is connected between the cable 10 and the second power terminal. As can be understood, when the plug 4 and the socket 5 are plugged together, the first power terminal 43 on the socket 5 is electrically connected to the second power terminal through surface contact, helping to provide a stable current transmission path. The conductor portion connects the cable 10 and the second power terminal of the plug 4. The conductor portion is the primary medium for transmitting current from the cable 10 to the second power terminal. It can carry current without overheating. The copper busbar 9 is responsible for transmitting current between the socket 5 and the plug 4, ensuring the stability and safety of current transmission.
