[0035] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0036] Example 1:

[0037] like Figures 1 to 7 As shown, the energy storage connector includes a socket 1 and a plug 2 that engages with the socket 1. The plug 2 has an installation space 4 and a locking mechanism 3. The installation space 4 has an installation cavity 41. When the locking mechanism 3 is in the locked state, the socket 1 and the plug 2 can remain in the plugged state. When the locking mechanism 3 is in the unlocked state, the socket 1 and the plug 2 can switch between the disconnected state and the plugged state. The locking mechanism 3 includes a locking member 31 that is inserted into the installation cavity 41 of the installation space 4. The locking member 31 is configured to perform a clamping action on the socket 1 that engages with the plug 2. The locking mechanism 3 also includes a stop member 33 configured to restrict the movement of the locking member 31. When the stop member 33 is in the stopped state, the locking mechanism 3 can remain in the locked state. When the stop member 33 is in the released state, the locking mechanism 3 can switch between the locked state and the unlocked state. In this embodiment, the locking member 31 can generate elastic deformation after being pressed to apply elastic clamping force, thereby improving the reliability of clamping. Of course, the locking member 31 can also be made of a material that does not generate elastic deformation after being pressed, but the clamping effect will be slightly reduced.

[0038] It should be noted that, for ease of explanation, the instructions attached here are used as a reference. Figure 6 Based on this reference, the side of the pressing part 311 facing away from the plug 2 and socket 1 is considered upper, and the side of the pressing part 311 facing the plug 2 and socket 1 is considered lower. The two sides of the pressing part 311 along its width are left and right, respectively. The locking of the plug 2 and socket 1 is achieved by the locking member 31. (Refer to...) Figure 6 and Figure 7The locking member 31 in the embodiment is in the shape of an inverted "U" as a whole and can be annularly arranged outside the socket 1. The locking member 31 comprises a pressing portion 311 exposed above the mounting cavity 41 and extending downward along both sides of the pressing portion 311 to form left and right extension arms. The pressing portion 311 can facilitate the pressing action of the operator, and the left and right extension arms can move synchronously with the pressing portion 311 to achieve the unlocking or locking of the plug 2 and the socket 1.

[0039] Specifically, each extension arm comprises a first extension portion 312 and a second extension portion 313 arranged adjacently and capable of extending into the interior of the mounting cavity 41. The first extension portion 312 serves to keep the locking member 31 fixed. The first extension portion 312 is outwardly protruded on the side facing the socket 1 to form a first buckle 314 capable of being clamped on the first clamping groove 21 in the interior of the plug 2 to achieve the fixation. Meanwhile, the second extension portion 313 serves to achieve the fixation of the plug 2 and the socket 1. By arranging the connected inclined portion 3131 and flat portion 3132, the inclined portion 3131 can be clamped on the peripheral surface of the socket 1, and the flat portion 3132 can be clamped in the interior of the plug 2. At this time, the plug 2 and the socket 1 cannot move relatively to achieve the locking.

[0040] To lock the plug 2 and socket 1, the operator can manually apply an upward force to the locking member 31, so that the first latch 314 can be engaged inside the plug 2, and the inclined part 3131 can be locked on the circumferential surface of the socket 1. For ease of operation, the locking mechanism 3 in this embodiment also includes an elastic member 32. The elastic member 32 is located below the force-bearing surface of the locking member 31 and makes elastic contact with the locking member 31. The elastic member 32 is elastically and extensibly arranged in the mounting cavity 41 of the mounting space 4. A gap C is formed between the force-bearing surface of the locking member 31 and the bottom of the mounting cavity 41, which can change the size of the gap as the locking member 31 moves back and forth in the direction of the pressing force. When the pressing force is applied, the locking member 31 will move downward as a whole, at which time the plug 2 and the socket 1 can move relative to each other; when the pressing force is removed, under the elastic action of the elastic member 32, the locking member 31 moves upward, so that the inclined part 3131 on the second extension 313 can be locked on the circumference of the socket 1, while the straight part 3132 can be locked inside the plug 2, at which time the plug 2 and the socket 1 remain fixed. It should be noted that the socket 1 has a groove 11 on its circumferential surface that mates with the second extension 313. When the socket 1 and plug 2 are in the plugged-in state, the second extension 313 is engaged in the groove 11. Due to the blocking effect of the second extension 313, the socket 1 cannot move in the plugging direction. In addition, the second extension 313 has a guide surface extending along the plugging direction of the socket 1. When the locking mechanism 3 is in the locked state and the anti-retraction member 33 is in the anti-retraction state, due to the presence of the guide surface, when the socket 1 switches from the separated state to the plugged-in state, the socket 1 can drive the locking mechanism 3 to overcome the elastic effect of the elastic member 32 and move accordingly. The locking mechanism 3 switches from the locked state to the unlocked state. When the socket 1 is plugged in, the locking mechanism 3 switches from the unlocked state to the locked state under the elastic effect of the elastic member 32, thereby keeping the socket 1 and plug 2 in the plugged-in state.

[0041] The elastic element 32 can be designed in various forms such as a spring or a sheet. In this embodiment, the elastic element 32 is a spring. Also, to facilitate the fixing of the elastic element 32, refer to... Figure 6 and Figure 7 In this embodiment, a limiting hole 411 for mounting the elastic member 32 is provided in the mounting cavity 41. The bottom of the elastic member 32 abuts against the limiting hole 411, and its top abuts against the pressing part 311. The function of the elastic member 32 is: when the locking member 31 is in the pressed state, the elastic force of the elastic member 32 can make the locking member 31 return to the upward; when the locking member 31 is not in the pressed state, the elastic force of the elastic member 32 can make the first buckle 314 lock into the first slot 21.

[0042] refer to Figure 4, the plug 2 and the socket 1 are in the first locking state, at this time, the lower part of the pressing part 311 and the bottom of the installation cavity 41 form a clearance C, if the pressing part 311 is pressed to the clearance C, the plug 2 and the socket 1 can be unlocked, in order to prevent the locking part 31 from unlocking, the retreat stop part 33 in the embodiment includes a main body part 331, the main body part 331 extends along the plug-in direction of the plug 2 and the socket 1 and forms two stop arms 332, the top of each stop arm 332 is partially expanded and forms a stop part 3321 which can extend into the clearance C, under the action of external force, the stop part 3321 can extend into the clearance C, thereby preventing the locking part 31 from moving to the bottom of the installation cavity 41 to complete the unlocking action.

[0043] In addition, since the retreat stop part 33 can move forward and backward along the sliding groove 42, and the retreat stop part 33 needs to move into the clearance C to achieve the second locking, it is necessary to fix the position of the retreat stop part 33, the main body part 331 in the embodiment is provided with a locking part 333, the top of the locking part 333 is partially protruded and forms a second buckle 3331, the outer surface of the plug 2 is provided with the sliding groove 42, the upper part of the sliding groove 42 is provided with the second clamping groove 22, and the retreat stop part 33 can be clamped on the second clamping groove 22 during the movement along the plug-in direction, thereby being fixed.

[0044] The working principle of the energy storage connector in the embodiment is as follows:

[0045] Reference Figure 2 , the plug 2 and the socket 1 are in the separated state, at this time, the plug 2 is moved to make the plug 2 and the socket 1 be plugged (the plug-in direction is the direction in which the plug 2 moves to the socket 1), when the first buckle 314 is clamped on the first clamping groove 21, the inclined part 3131 of the second extension part 313 can be clamped on the peripheral surface of the socket 1 and the flat part 3132 can be clamped on the inside of the plug 2, at this time, the plug 2 and the socket 1 are in the first locking state (reference Figure 4 ), the pressing part 311 and the bottom of the installation cavity 41 form a clearance C, the retreat stop part 33 is moved along the plug-in direction until the stop part 3321 extends into the clearance C, at this time, the second buckle 3331 is clamped on the second clamping groove 22 to be fixed, and the pressing part 311 cannot be moved downward to be unlocked under the stop action of the stop part 3321, at this time, the plug 2 and the socket 1 are in the second locking state (reference Figure 5 );

[0046] When it is needed to separate the plug 2 and the socket 1, the second buckle 3331 on the retreat-stop piece 33 is pressed by a tool and moved in the reverse direction of the plug-in direction, so that the stop portion 3321 is moved out of the neutral gap C, then the pressing portion 311 is pressed downward by the operator toward the bottom of the mounting cavity 41, so that the first buckle 314 is moved out of the first slot 21, and the inclined portion 3131 of the second extension portion 313 is moved out of the peripheral surface of the socket 1, at this time, the plug 2 and the socket 1 are in the unlocked state (see Figure 3 ), and the plug 2 and the socket 1 can be separated by moving the plug 2 in the reverse direction of the plug-in direction.

[0047] Embodiment 2

[0048] The energy storage connector in this embodiment has basically the same structure as that in Embodiment 1, and the difference is only in the matching mode of the locking piece 31 and the retreat-stop piece 33. The locking piece 31 in this embodiment is provided with a recess / protrusion on the side close to the retreat-stop piece 33, and the retreat-stop piece 33 is provided with a protrusion / recess matched with the locking piece 31. The specific working principle is as follows: when the plug 2 and the socket 1 are in the primary locked state, the retreat-stop piece 33 can be moved in the plug-in direction, so that the protrusion / recess on the retreat-stop piece 33 is inserted into the recess / protrusion of the locking piece 31, thereby limiting the downward movement of the entire locking piece 31 for unlocking, at this time, the plug 2 and the socket 1 are in the secondary locked state (see Figure 5 ); when it is needed to separate the plug 2 and the socket 1, the retreat-stop piece 33 is moved in the reverse direction of the plug-in direction, so that the plug 2 and the socket 1 can be separated by pressing the pressing portion 311.
