[0032] In addition, the terms "first", "second", etc. are used only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated thereby. Thus, the features defined with "first", "second", etc. can include one or more of the features explicitly or implicitly. In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise specified.

[0033] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0034] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0035] like Figures 1-12 An energy storage connector is shown, comprising a plug 1 and a socket 2 that are plugged into each other. The socket 2 has a slot 3, and the plug 1 has a terminal 4 that mates with the slot 3. The connector is characterized in that: the plug 1 has a female end core 5 sleeved on the outside of the terminal 4, and the female end core 5 can abut and engage with the inner wall of the slot 3; the outer wall of the terminal 4 has a terminal groove 6 circumferentially provided, and the end of the female end core 5 has a hook 7 that engages with the terminal groove 6; after the plug 1 and the socket 2 are plugged in, the plug 1 can rotate circumferentially relative to the female end core 5 and the socket 2 through the engagement of the hook 7 and the terminal groove 6.

[0036] In the above technical solution, after the plug 1 and socket 2 are inserted, the female end core 5 on the plug 1 abuts and locks against the slot 3 on the socket 2. Furthermore, since the female end core 5 has a hook 7 on its inner side and a terminal groove 6 on the outer wall of the terminal, the hook 7 hooks into the terminal groove 6, allowing the plug 1 to rotate 360° relative to the socket 2. This makes it easier for the energy storage connector to connect to external circuits. It should be noted that the female end core 5 provides some protection for the inside of the slot and the terminals.

[0037] Furthermore, the hook 7 is circumferentially formed on the inner side of the end of the female end core 5. In this technical solution, the circumferential arrangement of the hook 7 can increase the contact area between the hook 7 and the terminal slot 6, making it less likely for the hook 7 to detach after engaging with the terminal slot 6, and facilitating the rotation between the plug 1 and the socket 2.

[0038] Further, the hook 7 has an end face abutting against the terminal groove 6 and a slope 8 abutting against the groove opening of the terminal groove 6. In the technical scheme, the end face can prevent the hook from being separated from the terminal groove during use of the energy storage connector; and the slope has a certain guiding property and can assist the hook 7 to be separated from the terminal groove 6 when maintenance is needed.

[0039] Further, a plurality of first foolproof ribs are arranged on the inner wall of the insertion groove 3, and a clamping groove 9 is formed between adjacent first foolproof ribs; a plurality of second foolproof ribs are arranged on the side wall of the female rubber core 5 and matched with the clamping groove 9, and a butt joint groove 10 matched with the first foolproof rib is formed between adjacent second foolproof ribs. In the technical scheme, the clamping and matching of the first foolproof rib and the second foolproof rib can not only effectively prevent the error between the plug 1 and the socket 2, but also effectively lock the female rubber core in the circumferential direction, facilitating the circumferential rotation of the plug.

[0040] Further, the plurality of first foolproof ribs are arranged on the inner wall of the insertion groove 3 in the circumferential direction, and the plurality of second foolproof ribs are arranged on the side wall of the female rubber core 5 in the circumferential direction. In the technical scheme, the axial arrangement of the first foolproof rib and the second foolproof rib can make the force between the female rubber core and the socket more uniform, avoiding that the first foolproof rib and the second foolproof rib are seriously worn due to excessive force at a certain position.

[0041] Further, the outer end face of the first foolproof rib has a first cutting surface 11 inclined downward and inward, and the outer end face of the second foolproof rib has a second cutting surface 12 inclined downward and outward. In the technical scheme, the first cutting surface 11 and the second cutting surface 12 both have a certain guiding property and are used to guide the movement of the female rubber core 5 and the socket 2 after the cutting surfaces contact the two side edges, so as to realize the quick assembly of the female rubber core 5 and the socket 2.

[0042] Further, the side walls on both sides of the second foolproof rib are inclined to make the butt joint groove 10 a trapezoidal groove with the groove opening gradually increasing inward. In the technical scheme, the trapezoidal groove between the second foolproof ribs on the female rubber core 5 can increase the holding force of the second foolproof rib on the first foolproof rib, so that the two are more closely connected, and the structure of the female rubber core 5 and the socket 2 after butt joint is more stable.

[0043] Further, the plug 1 includes a plug A with a second foolproof rib A13 and a plug N with a second foolproof rib N14; the socket 2 includes a socket A15 adapted to the plug A and a socket N16 adapted to the plug N, the socket A15 has a first foolproof rib A17 abutting against the second foolproof rib A13, and the socket 2N has a first foolproof rib N18 abutting against the second foolproof rib N16. In this technical solution, the plug 1 and the socket 2 in the case correspond to two kinds respectively, that is, the plug A and the socket A and the plug N and the socket N, and the specific difference between the two is that the number of corresponding foolproof ribs is different. In addition, in terms of actual application, the colors are also distinguished, that is, the plug A and the socket A are black, and the plug N and the socket N are orange.

[0044] Further, the side wall of the socket 3 is circumferentially provided with a plurality of reinforcing ribs 19; the plug 1 is provided with a mounting groove 20, the terminal 4 and the female core 5 are arranged in the mounting groove 20, and an annular groove 21 adapted to the socket wall of the socket 3 is formed between the outer wall of the female core 5 and the mounting groove 20. In this technical solution, the reinforcing ribs 19 on the socket 3 are provided, specifically, the reinforcing ribs 19 are inclined ribs connected to the socket base, which can increase the strength of the socket. The cooperation of the socket wall and the annular groove can prevent the socket and the plug from shaking after being inserted.

[0045] Further, the socket 3 is provided with a plug pin 22 for conducting electricity, and the terminal 4 is provided with a conductive groove 23 adapted to and electrically connected to the plug pin 22; one end of the hook 7 on the female core 5 is circumferentially provided with a plurality of cutouts 24. In this technical solution, the plurality of cutouts 24 on the female core increase the flexibility of the end of the female core, facilitating the disassembly and assembly of the female core, and the other side of the female core is also provided with an arc-shaped opening, which can play a certain heat dissipation role and increase the flexibility.

[0046] In this specific embodiment, in view of the inconvenience of connecting the existing energy storage connector with the external circuit and the possible error between the plug 1 and the socket 2 in the energy storage connector, the above-mentioned scheme is to set the female core 5 on the terminal of the plug 1, the female core 5 has a second foolproof rib, which can cooperate with the first foolproof rib in the socket slot to effectively prevent errors, and the cooperation of the terminal groove 6 on the terminal and the hook 7 in the female core 5 further realizes the circumferential rotation between the plug 1 and the socket 2. This scheme is simple in structure and strong in practicability, effectively improves the installation efficiency between the energy storage connector and the external circuit, and avoids unnecessary damage of the energy storage connector caused by errors.
