In addition, the terms "first", "second" are used to distinguish the description, and have no special meaning.

[0032] As shown in FIGS. 1-7, in a first aspect, embodiments of the present application provide a connector plug. The connector plug 1 comprises a body 10, one end of the body 10 is provided with a first connecting part 20, the other end of the body 10 is provided with a second connecting part 30, the first connecting part 20 is arranged to be connected with a cable, and the second connecting part 30 is arranged to be plugged with a connector socket; wherein the second connecting part 30 can rotate at least 180° relative to the body 10.

[0033] By applying the technical scheme of the present application, the second connecting part 30 is arranged to rotate at any angle relative to the body 10, so that when the second connecting part 30 is plugged with the connector socket, the outlet direction can be adjusted by rotating the second connecting part 30, thereby facilitating the installation adjustment of the connector, thereby improving the installation efficiency of the connector.

[0034] In some embodiments, a plurality of annular protrusions 13 are arranged on one of the inner side wall of the second connecting portion 30 and the outer side wall of the body 10, and the plurality of annular protrusions 13 are arranged along the axial direction of the outer side wall of the body 10. The plurality of annular protrusions 13 are matched with the other of the inner side wall of the second connecting portion 30 and the outer side wall of the body 10 to form a rotating structure, and the second connecting portion 30 is relatively rotated with the body 10 through the rotating structure. In the present application, the annular protrusions 13 are arranged on the outer side wall of the body 10. Through the above structure, the free rotation of the second connecting portion 30 is realized, and the above structure is simple, so that the processing of the structure is facilitated, and the processing difficulty of the structure is reduced.

[0035] In some embodiments, the second connecting portion 30 has an annular structure which is matched with the connector socket. The diameter of the annular structure is R1, and 29mm≤R1≤30mm. When R1>30mm, the cross-sectional structure of the second connecting portion 30 is too large, which increases the material required in the production of the second connecting portion 30, and thus the production cost of the second connecting portion 30 is increased to a certain extent. Meanwhile, the second connecting portion 30 which is too large also occupies extra installation space, which is not conducive to the installation of other components. When R1<29mm, the cross-sectional structure of the second connecting portion 30 is too small, which may not facilitate the plug-in cooperation with the connector socket, and thus the efficiency of the plug-in cooperation is reduced. Therefore, 29mm≤R1≤30mm not only reduces the material required in the production of the second connecting portion 30, and thus the production cost of the second connecting portion 30 is reduced to a certain extent, but also does not make the second connecting portion 30 occupy extra installation space, which is conducive to the installation of other components, and also facilitates the plug-in cooperation with the connector socket, and thus the efficiency of the plug-in cooperation is improved. Alternatively, R1 can be set as 29mm, 29.5mm or 30mm, and the specific setting should be selected according to the use environment of the second connecting portion 30, which is not limited here.

[0036] In some embodiments, the second connecting portion 30 has an axial extension length L1 of the connection between the second connecting portion 30 and the connector socket, and 31.4mm≤L1≤32.4mm. When L1>32.4mm, the axial extension length of the connection between the second connecting portion 30 and the connector socket is too large, which increases the material required for the production of the second connecting portion 30, and thus increases the production cost of the second connecting portion 30 to some extent. Meanwhile, the second connecting portion 30 with an excessively large size occupies extra installation space, which is not conducive to the installation of other components. When L1<31.4mm, the axial extension length of the connection between the second connecting portion 30 and the connector socket is too small, which reduces the contact area of the connection between the second connecting portion 30 and the connector socket, and thus is not conducive to the plug-in cooperation with the connector socket, and reduces the stability of the connection between them. Therefore, 31.4mm≤L1≤32.4mm not only reduces the material required for the production of the second connecting portion 30, and thus reduces the production cost of the second connecting portion 30 to some extent, but also ensures the contact area of the connection between the second connecting portion 30 and the connector socket, and thus is conducive to the plug-in cooperation with the connector socket, and improves the stability of the connection between them. Alternatively, L1 can be set to 31.4mm, 32mm or 32.4mm, and the specific setting should be selected according to the use environment of the second connecting portion 30, which is not limited herein.

[0037] In some embodiments, the first connecting portion 20 has an radial extension length L2 of the second connecting portion 30, and 31.7mm≤L2≤32.7mm. When L2>32.7mm, the radial extension length of the first connecting portion 20 is too large, which increases the material required for the production of the first connecting portion 20, and thus increases the production cost of the first connecting portion 20 to some extent. Meanwhile, the first connecting portion 20 with an excessively large size occupies extra installation space, which is not conducive to the installation of other components. When L2<31.7mm, the radial extension length of the first connecting portion 20 is too small, which reduces the contact area of the connection between the first connecting portion 20 and the cable, and thus is not conducive to the plug-in cooperation with the connector socket, and reduces the stability of the connection between them. Therefore, 31.7mm≤L2≤32.7mm not only reduces the material required for the production of the first connecting portion 20, and thus reduces the production cost of the first connecting portion 20 to some extent, but also ensures the contact area of the connection between the first connecting portion 20 and the cable, and thus is conducive to the plug-in cooperation with the cable, and improves the stability of the connection between them. Alternatively, L2 can be set to 31.7mm, 32mm or 32.7mm, and the specific setting should be selected according to the use environment of the first connecting portion 20, which is not limited herein.

[0038] In some implementations, the connector plug 1 has an axial extension length L3 along the first connecting portion 20, and 105.85mm≤L3≤107.85mm. When L3>107.85mm, the axial extension length of the connector plug 1 along the first connecting portion 20 is too large, which increases the material required for the production of the connector plug 1, and thus increases the production cost of the connector plug 1 to some extent. Meanwhile, the excessively large connector plug 1 also occupies extra installation space, which is not conducive to the installation of other components. When L3<105.85mm, the axial extension length of the connector plug 1 along the first connecting portion 20 is too small, which reduces the contact area of the connector plug 1 when connected with other components, and thus is not conducive to the connection and cooperation with other components, and reduces the stability during connection. Therefore, 105.85mm≤L3≤107.85mm not only reduces the material required for the production of the connector plug 1, and thus reduces the production cost of the connector plug 1 to some extent, but also ensures the contact area of the connection between the connector plug 1 and other components, and thus facilitates the connection and cooperation with other components, and improves the stability during connection. Alternatively, L3 can be set as 105.85mm, 106mm or 107.85mm, and the specific setting should be selected according to the use environment of the connector plug 1, which is not limited herein.

[0039] In some implementations, the connector plug 1 has an axial extension length L4 along the second connecting portion 30, and 67.7mm≤L4≤68.7mm. When L4>68.7mm, the axial extension length of the connector plug 1 along the second connecting portion 30 is too large, which increases the material required for the production of the connector plug 1, and thus increases the production cost of the connector plug 1 to some extent. Meanwhile, the excessively large connector plug 1 also occupies extra installation space, which is not conducive to the installation of other components. When L4<67.7mm, the axial extension length of the connector plug 1 along the second connecting portion 30 is too small, which reduces the contact area of the connector plug 1 when connected with other components, and thus is not conducive to the connection and cooperation with other components, and reduces the stability during connection. Therefore, 67.7mm≤L4≤68.7mm not only reduces the material required for the production of the connector plug 1, and thus reduces the production cost of the connector plug 1 to some extent, but also ensures the contact area of the connection between the connector plug 1 and other components, and thus facilitates the connection and cooperation with other components, and improves the stability during connection. Alternatively, L4 can be set as 67.7mm, 68mm or 68.7mm, and the specific setting should be selected according to the use environment of the connector plug 1, which is not limited herein.

[0040] In some implementations, an end of the second connecting portion 30 close to the body 10 is provided with a limiting protrusion 32, and the body 10 is provided with a limiting groove 14 corresponding to the limiting protrusion 32, and the limiting protrusion 32 and the limiting groove 14 are in clamping cooperation to limit the position of the second connecting portion 30 relative to the body 10. By setting the above structure, the phenomenon that the second connecting portion 30 is displaced relative to the body 10 during use can be prevented, thereby ensuring the stability of the connector plug 1 during use.

[0041] In some implementations, the body 10 includes a first segment 11 and a second segment 12 connected in sequence and at an included angle, an end of the first segment 11 away from the second segment 12 is connected with the first connecting portion 20, an end of the second segment 12 away from the first segment 11 is connected with the second connecting portion 30, and the second connecting portion 30 can rotate at least 180° along the axis of the second segment 12. In this way, mutual interference between the first connecting portion 20 and the second connecting portion 30 is avoided, thereby facilitating the stable operation of the connector plug 1. In the present application, the angle between the first segment 11 and the second segment 12 is a right angle, which not only facilitates the processing of the first segment 11 and the second segment 12, but also reduces the processing difficulty of the first segment 11 and the second segment 12, thereby facilitating the processing efficiency of the first segment 11 and the second segment 12.

[0042] In some implementations, the connector plug 1 further includes a buckle 40, the buckle 40 is swingably arranged on the outer side wall of the second segment 12, the swing axis of the buckle 40 is perpendicular to the axis of the second segment 12, and the buckle 40 is arranged to fix the connector plug 1 and the connector socket. By setting the above structure, when the connector plug 1 and the connector socket are installed, the buckle 40 can prevent the connector plug 1 and the connector socket from being loose, thereby improving the stability during connection.

[0043] In some implementations, the material of the connector plug 1 includes zinc-nickel alloy. Since the zinc-nickel alloy has excellent corrosion resistance, its corrosion resistance is much better than that of pure zinc plating. At the same thickness, the corrosion resistance of the zinc-nickel alloy layer can reach 4-8 times that of the pure zinc plating layer, or even higher. Such corrosion resistance enables the zinc-nickel alloy to maintain long-term stable performance in various environments, including high temperature, high humidity, high salinity, and other special environments. Thus, the service life of the connector plug 1 can be extended, and the use cost of the connector plug 1 can be correspondingly reduced. Meanwhile, after specific heat treatment, the corrosion resistance of the zinc-nickel alloy can be further improved, while maintaining good resistance to thermal fatigue. The corrosion resistance of the zinc-nickel alloy almost does not change between -60°C and 250°C after quenching and heat treatment. In addition, the zinc-nickel alloy has high strength and hardness, which is more than 30% higher than that of traditional zinc alloy. This enables the zinc-nickel alloy to maintain stable performance in various harsh environments and has good wear resistance, so as to meet the 720h salt spray level and can be used in marine application conditions.

[0044] In some implementations, the outer surface of the connector plug 1 is provided with an insulating coating. By setting the above structure, the outer surface of the connector plug 1 can be provided with electrical insulation to prevent current from flowing in the unwanted path, ensure that the electrical parts inside and outside the connector are isolated from each other, and thus ensure the normal operation of electrical equipment and personnel safety. Meanwhile, the materials of the insulating coating, such as epoxy powder and organic-inorganic composite coating, have good corrosion resistance. These coatings can resist the corrosion of moisture, oxygen, chemicals, and other substances in the environment, thereby prolonging the service life of the connector plug 1.

[0045] In some implementations, the connector plug 1 also has a plurality of key positions 50, which are arranged on the outer side wall of the second connecting portion 30 along the circumference of the second connecting portion 30. The key positions 50 are arranged to be matched with the key position 50 slots on the connector socket. When the connector plug 1 is plugged into the connector socket, the key positions 50 are plugged into the key position 50 slots, and the connector plug 1 is electrically connected to the connector socket. In this way, the positions of different key positions 50 on the connector plug 1 can be matched, and the need for foolproofing of the connector can be met, thereby reducing the production cost without the need to develop a new mold.

[0046] In a second aspect, the embodiments of the present application provide a power storage device. As shown in FIG. 8, the power storage device 100 includes the above-mentioned connector plug 1.

[0047] According to the technical scheme, the second connecting part 30 is arranged to be rotatable relative to the body 10 by any angle, so that when the second connecting part 30 is plugged with the connector socket, the outlet direction can be adjusted by rotating the second connecting part 30, thereby facilitating the installation adjustment of the connector, improving the installation efficiency of the connector, and further improving the installation efficiency of the energy storage device.
