[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0034] like Figures 1 to 7As shown, in the first aspect, an embodiment of the present invention provides a connector plug, which includes: a body 10, a first connecting portion 20 is provided at one end of the body 10, and a second connecting portion 30 is provided at the other end of the body 10, the first connecting portion 20 is used to connect to the cable, and the second connecting portion 30 is used to plug and mate with the connector socket; wherein the second connecting portion 30 can be rotated at least 180° relative to the body 10.

[0035] By applying the technical solution of the present invention, the second connecting part 30 is configured to be rotatable at any angle relative to the main body 10. Therefore, when the second connecting part 30 is plugged into the connector socket, the output direction of the line can be adjusted by rotating the second connecting part 30, thereby facilitating the installation and adjustment of the connector, thereby improving the installation efficiency of the connector.

[0036] In one embodiment, a plurality of annular protrusions 13 are provided on one of the inner sidewall of the second connecting portion 30 and the outer sidewall of the body 10. These annular protrusions 13 are spaced apart axially along the outer sidewall of the body 10. These annular protrusions 13 cooperate with the other inner sidewall of the second connecting portion 30 and the outer sidewall of the body 10 to form a rotational structure, enabling relative rotation of the second connecting portion 30 and the body 10. In the present application, the annular protrusions 13 are provided on the outer sidewall of the body 10. This structure not only enables free rotation of the second connecting portion 30 but also simplifies the structure, facilitating fabrication and reducing its difficulty.

[0037] In one embodiment, the second connecting portion 30 has an annular structure that abuts the connector receptacle. The annular structure has a diameter R1, 29 mm ≤ R1 ≤ 30 mm. When R1 is greater than 30 mm, the cross-section of the second connecting portion 30 is too large, which increases the material required for production and, therefore, increases the production cost. Furthermore, an overly large second connecting portion 30 also occupies additional installation space, hindering the installation of other components. When R1 is less than 29 mm, the cross-section of the second connecting portion 30 is too small, which may hinder mating with the connector receptacle and reduce mating efficiency. Therefore, adjusting the diameter to 29 mm ≤ R1 ≤ 30 mm not only reduces the material required for production of the second connecting portion 30, thereby reducing its production cost, but also reduces the space required for installation, facilitating the installation of other components and facilitating mating with the connector receptacle, thereby improving mating efficiency. Optionally, R1 can be set to a value such as 29 mm, 29.5 mm or 30 mm. The specific setting should be selected according to the use environment of the second connecting part 30 and is not specifically limited here.

[0038] In one embodiment, the axial extension length of the second connection portion 30 at the connection between the second connection portion 30 and the connector receptacle is L1, and 31.4 mm ≤ L1 ≤ 32.4 mm. When L1 is greater than 32.4 mm, the axial extension length of the second connection portion 30 at the connection between the second connection portion 30 and the connector receptacle is too large, which increases the material required for the production of the second connection portion 30 and, to a certain extent, increases the production cost of the second connection portion 30. Furthermore, an oversized second connection portion 30 also occupies additional installation space, hindering the installation of other components. When L1 is less than 31.4 mm, the axial extension length of the second connection portion 30 at the connection between the second connection portion 30 and the connector receptacle is too small, which reduces the contact area between the second connection portion 30 and the connector receptacle, making it difficult to plug and match the connector receptacle and reducing the stability of the connection between the two. Therefore, setting 31.4mm ≤ L1 ≤ 32.4mm not only reduces the material required to produce the second connecting portion 30, thereby reducing the production cost to a certain extent, but also ensures the contact area between the second connecting portion 30 and the connector receptacle, thereby facilitating plug-in mating with the connector receptacle and improving the stability of the connection between the two. Optionally, L1 can be set to 31.4mm, 32mm, or 32.4mm, etc. The specific setting should be selected based on the usage environment of the second connecting portion 30 and is not specifically limited here.

[0039] In one embodiment, the radial extension length of the first connecting portion 20 along the second connecting portion 30 is L2, and 31.7 mm ≤ L2 ≤ 32.7 mm. When L2 is greater than 32.7 mm, the radial extension length of the first connecting portion 20 along the second connecting portion 30 is too large, which increases the material required for production of the first connecting portion 20, thereby increasing the production cost of the first connecting portion 20 to a certain extent. Furthermore, an oversized first connecting portion 20 also occupies additional installation space, hindering the installation of other components. When L2 is less than 31.7 mm, the radial extension length of the first connecting portion 20 along the second connecting portion 30 is too small, which reduces the contact area between the first connecting portion 20 and the cable, making it difficult to plug and mate with the connector receptacle and reducing the stability of the connection between the two. Therefore, setting 31.7 mm ≤ L2 ≤ 32.7 mm not only reduces the material required for production of the first connecting portion 20, thereby reducing the production cost of the first connecting portion 20 to a certain extent, but also ensures the contact area between the first connecting portion 20 and the cable, facilitating connection and mating with the cable and improving the stability of the connection between the two. Optionally, L2 can be set to a value such as 31.7 mm, 32 mm or 32.7 mm. The specific setting should be selected according to the use environment of the first connecting part 20 and is not specifically limited here.

[0040] In one embodiment, the axial extension length of the connector plug along the first connecting portion 20 is L3, and 105.85 mm ≤ L3 ≤ 107.85 mm. When L3 is greater than 107.85 mm, the axial extension length of the connector plug along the first connecting portion 20 is too large, which increases the material required for the connector plug's production, thereby increasing the connector plug's production cost to a certain extent. Furthermore, an oversized connector plug also occupies additional installation space, hindering the installation of other components. When L3 is less than 105.85 mm, the axial extension length of the connector plug along the first connecting portion 20 is too small, which reduces the contact area when the connector plug connects to other components, making it difficult to connect and mate with other components and reducing the stability of the connection. Therefore, setting 105.85 mm ≤ L3 ≤ 107.85 mm not only reduces the material required for the connector plug's production, thereby reducing the connector plug's production cost to a certain extent, but also ensures the contact area between the connector plug and other components, facilitating the connection and mate with other components and improving the stability of the connection. Optionally, L3 can be set to values such as 105.85 mm, 106 mm or 107.85 mm. The specific setting should be selected according to the use environment of the connector plug and is not specifically limited here.

[0041] In one embodiment, the axial extension length of the connector plug along the second connecting portion 30 is L4, and 67.7 mm ≤ L4 ≤ 68.7 mm. When L4 is greater than 68.7 mm, the axial extension length of the connector plug along the second connecting portion 30 is too large, which increases the material required for the connector plug's production, thereby increasing the production cost of the connector plug to a certain extent. Furthermore, an oversized connector plug also occupies additional installation space, hindering the installation of other components. When L4 is less than 67.7 mm, the axial extension length of the connector plug along the second connecting portion 30 is too small, which reduces the contact area when the connector plug is connected to other components, making it difficult to connect and cooperate with other components and reducing the stability of the connection. Therefore, setting 67.7 mm ≤ L4 ≤ 68.7 mm not only reduces the material required for the connector plug's production, thereby reducing the production cost of the connector plug to a certain extent, but also ensures the contact area between the connector plug and other components, thereby facilitating the connection and cooperation with other components and improving the stability of the connection. Optionally, L4 can be set to values such as 67.7 mm, 68 mm or 68.7 mm. The specific setting should be selected according to the use environment of the connector plug and is not specifically limited here.

[0042] In one embodiment, a limiting protrusion 32 is provided on one end of the second connecting portion 30 that is adjacent to the body 10. A limiting groove 14 is provided on the body 10 that corresponds to the limiting protrusion 32. The limiting protrusion 32 engages with the limiting groove 14 to limit the position of the second connecting portion 30 relative to the body 10. This structure prevents the second connecting portion 30 from being displaced relative to the body 10 during use, thereby ensuring the stability of the connector plug during use.

[0043] In one embodiment, the body 10 includes a first section 11 and a second section 12 connected in series and arranged at an angle. The end of the first section 11 distal to the second section 12 is connected to the first connecting portion 20, and the end of the second section 12 distal to the first section 11 is connected to the second connecting portion 30. The second connecting portion 30 can rotate at least 180° along the axis of the second section 12. This arrangement prevents interference between the first connecting portion 20 and the second connecting portion 30, thereby facilitating stable operation of the connector plug. In the present application, the angle between the first section 11 and the second section 12 is a right angle. This not only facilitates the processing of the first and second sections 11, 12, but also reduces the processing difficulty and improves the processing efficiency of the first and second sections 11, 12.

[0044] In one embodiment, the connector plug further includes a latch 40, which is swingably mounted on the outer sidewall of the second section 12, with the latch 40's swing axis perpendicular to the axis of the second section 12. The latch 40 is used to secure the connector plug to the connector receptacle. This structure prevents the connector plug and the connector receptacle from becoming loose after they are assembled, thereby improving the stability of the connection between the two.

[0045] In one embodiment, the connector plug is made of a zinc-nickel alloy. Due to its excellent corrosion resistance, zinc-nickel alloy far surpasses pure zinc plating. At the same thickness, the corrosion resistance of a zinc-nickel alloy layer can be 4-8 times, or even higher, than that of a pure zinc plating layer. This corrosion resistance enables the zinc-nickel alloy to maintain long-term stable performance in a variety of environments, including those with high temperatures, high humidity, and high salinity. This extends the service life of the connector plug and correspondingly reduces its operating cost. Furthermore, after undergoing specific heat treatment, the zinc-nickel alloy's corrosion resistance can be further enhanced while maintaining excellent thermal fatigue resistance. Rapid cooling and heat treatment between -60°C and 250°C produces virtually no change in corrosion resistance. Furthermore, the zinc-nickel alloy boasts high strength and hardness, with a hardness over 30% higher than that of conventional zinc alloys. This ensures the zinc-nickel alloy maintains stable performance in a variety of harsh environments and offers excellent wear resistance, enabling it to meet a 720h salt spray rating and be used in marine applications.

[0046] In one embodiment, the outer surface of the connector plug is provided with an insulating coating. This structure provides electrical insulation to the outer surface of the connector plug, preventing current from flowing along undesirable paths and ensuring isolation between the internal and external electrical components of the connector, thereby ensuring the normal operation of electrical equipment and personnel safety. Furthermore, the insulating coating materials, such as epoxy powders and organic-inorganic composite coatings, exhibit excellent corrosion resistance. These coatings are resistant to corrosion by moisture, oxygen, and chemicals in the environment, thereby extending the service life of the connector plug.

[0047] In one embodiment, the connector plug further comprises a plurality of key positions 50, which are arranged along the circumference of the second connecting portion 30 on the outer sidewall of the second connecting portion 30. The key positions 50 are configured to align with the key position 50 slots on the connector receptacle. When the connector plug and the connector receptacle are mated, the key positions 50 are inserted into the key position 50 slots, and the connector plug and the connector receptacle are electrically connected. This arrangement can match the positions of different key positions 50 on the connector plug and meet the requirements of foolproofing on the connector, thus eliminating the need for redeveloping molds and reducing production costs.

[0048] In a second aspect, an embodiment of the present invention provides an energy storage device, which includes the above-mentioned connector plug.

[0049] By applying the technical solution of the present invention, the second connecting part 30 is configured to be rotatable at any angle relative to the main body 10. Therefore, when the second connecting part 30 is plugged into the connector socket, the output direction of the line can be adjusted by rotating the second connecting part 30, thereby facilitating the installation and adjustment of the connector, thereby improving the installation efficiency of the connector.
