Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of connectors, in particular to a connector and an energy storage device. BACKGROUND

[0002] The energy storage industry plays an important role in the process of power transmission and distribution, and has functions such as transmission, storage, peak regulation and energy replacement. The energy storage industry includes various energy storage systems, such as solar energy storage systems and wind energy storage systems. Among them, connectors are often used in the process of power transmission and distribution of various energy storage systems to connect various devices in the energy storage system and realize power transmission and distribution.

[0003] The types of connectors in the existing market are less in demand. In order to prevent the sockets and plugs in different types of connectors from being inserted incorrectly, the sizes of different types of connectors are differentiated, that is, the sizes of the sockets and plugs in different types of connectors are differentiated. The thickness of the shell in the connection structure of the sockets and plugs of different types and the thickness of the cavity accommodating the shell are different, so the sockets and plugs in different types of connectors cannot be completely plugged. However, in the prior art, when the sockets and plugs in different types of connectors are inserted incorrectly, a small part of the plug can still enter the socket, which poses a risk of conduction.

[0004] Therefore, on the basis of increasing the demand for types of connectors, if the size structure of the plugs and sockets in the existing connectors for preventing incorrect insertion is continued to be used, the thickness range of the shell of the sockets and plugs in the connectors and the thickness of the cavity accommodating the shell will increase, thereby causing the problem of increasing the overall size of the connectors. Content of the utility model

[0017] In some embodiments, a first limiting portion is arranged on the outer wall surface of the plug-in body, and a second limiting portion matched with the first limiting portion is arranged on the inner wall surface of the plug-in sleeve.

[0018] When the plug-in sleeve is sleeved on the plug-in body, the first limiting portion and the second limiting portion are matched with each other to limit the movement of the plug-in sleeve in the axial direction.

[0019] In some embodiments, the first limiting portion comprises one of a limiting protrusion and a limiting groove, and the second limiting portion comprises the other of the limiting protrusion and the limiting groove.

[0038] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are some of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the protection scope of the present application. In the case of no conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0039] In the related art, in order to prevent misplug between the socket and the plug in different types of connectors, the sizes of different types of connectors are distinguished, that is, the sizes of the socket and the plug in different types of connectors are distinguished. The thickness of the shell in the socket and plug connection structure of different types and the thickness of the cavity corresponding to the shell are different, so the socket and the plug in different types of connectors cannot be completely plugged. However, in the prior art, when the socket and the plug in different types of connectors are misplugged, a small part of the plug can still enter the socket, which poses a risk of conduction. Moreover, market demand changes and the demand for types of connectors increases. If the size structure of the plug and the socket in the existing connector for preventing misplug is continued to be used, the thickness range of the shell of the socket and the plug in the connector will increase, thereby causing the technical problem of increasing the overall size of the connector.

[0040] In order to overcome the defects in the related art, the embodiments of the present application provide a connector. A first matching structure is arranged on the socket in the connector, a second matching structure matched with the first matching structure is arranged on the plug in the connector, and then different types of first matching structures and different types of second matching structures are arranged to obtain different types of connectors. Only the first matching structure and the second matching structure in the same type of connector can be matched, so that the technical problem of preventing misplug of the socket and the plug in different types of connectors can be solved by changing only the types of the first matching structure and the second matching structure without changing the size of the connector.

[0041] The content of the present application will be described in detail below with reference to the drawings, so that those skilled in the art can more clearly and specifically understand the content of the present application.

[0042] As shown in Figure 1 and Figure 2 The connector 10 includes a socket 100 and a plug 200. The socket 100 includes a seat body 110, a plugging piece 120 arranged on the seat body 110, and a first coupling piece 130. The plugging piece 120 surrounds the outer circumferential side of the first coupling piece 130 and has a ring structure. At least two first matching structures 140 are arranged on the outer wall surface of the plugging piece 120 and are arranged at intervals along the circumference of the plugging piece 120. The plug 200 includes a plug body 210 and a second coupling piece 220. The plug body 210 has a plugging space 211 matched with the plugging piece 120. The second coupling piece 220 is arranged in the plugging space 211. The inner wall surface of the plugging space 211 has a second matching structure 230 matched with the first matching structure 140 at a position corresponding to each first matching structure 140. When the plugging piece 120 is inserted into the plugging space 211, the first matching structure 140 and the second matching structure 230 are matched with each other, and the first coupling piece 130 and the second coupling piece 220 are electrically coupled.

[0043] Therefore, different kinds of first matching structures are arranged on the outer wall surface of the plug-in piece 120 in the socket 100, including different numbers, shapes, and the like of the first matching structures arranged on the outer wall surface of the plug-in piece 120, and different kinds of second matching structures 230 matched with the first matching structures 140 are arranged on the inner wall surface of the plug-in space 211 in the plug 200, so that different kinds of connectors 10 can be obtained, and because the first matching structures 140 and the second matching structures 230 in the different kinds of connectors 10 are different, the effect of preventing the socket 100 and the plug 200 in the different kinds of connectors 10 from being inserted incorrectly can be achieved.

[0044] In some embodiments, the plug-in piece 120 arranged on the seat body 110 surrounds the outer circumferential side of the first coupling piece 130 and has a ring structure, which can be a circular ring, an elliptical ring, a square ring, or the like, and the shape of the plug-in space 211 in the plug body 210 matches the shape of the plug-in piece 120.

[0045] In some embodiments, as shown in Figs. 1 and 2, the plug-in piece 120 has a circular ring shape, and the first matching structures 140 are uniformly arranged on the outer wall surface of the plug-in piece 120. Figure 1 and Figure 2 As shown in Figs. 1 and 2, the plug-in piece 120 has a circular ring shape, and the first matching structures 140 are uniformly arranged on the outer wall surface of the plug-in piece 120. In addition, in the plug body 210 of the plug 200, the shape of the plug-in space 211 matches the shape of the plug-in piece 120, which is a circular ring shape, and the second matching structures 230 matched with the first matching structures 140 are uniformly distributed at positions corresponding to the first matching structures 140 on the inner wall surface of the plug-in space 211. When the plug-in piece 120 is inserted into the plug-in space 211, the first matching structures 140 and the second matching structures 230 cooperate with each other. Therefore, in different kinds of connectors 10, different kinds of first matching structures 140 are arranged on the outer wall surface of the plug-in piece 120, and different kinds of second matching structures 230 matched with the first matching structures 140 are arranged on the inner wall surface of the plug-in space 211, so that the plug-in piece 120 and the plug-in space 211 in different kinds of connectors 10 cannot be plugged in, thereby achieving the effect of preventing the socket 100 and the plug 200 in different kinds of connectors 10 from being inserted incorrectly.

[0046] In some embodiments, the first matching structures 140 are arranged on the plug-in piece 120 at positions where the plug-in space 211 is first plugged in, and the second matching structures 230 are arranged on the plug-in space 211 at positions where the plug-in piece 120 is first plugged in. Therefore, in different kinds of connectors 10, any part of the plug-in piece 120 cannot be inserted into the plug-in space 211 in another kind of connector 10, thereby avoiding the risk of conduction of the socket 100 and the plug 200 in different kinds of connectors 10 in the case of incorrect insertion.

[0047] In some embodiments, the first coupling member 130 and the second coupling member 220 can include components and structures for energization, such as conductive sheets, wires, coupling member plug-in parts, etc., the first coupling member 130 can be in the shape of a ring structure, which can be a circular ring, an elliptical ring, a square ring, etc., the second coupling member is provided with a coupling member plug-in space and a coupling member plug-in part matched therewith, and when the plug-in part 120 is plugged into the plug-in space 211, the first coupling member 130 is electrically coupled with the second coupling member 220.

[0048] When the first matching structure 140 is one of a matching protrusion and a matching groove, the second matching structure 230 is the other of the matching protrusion and the matching groove.

[0049] In some embodiments, as shown in Figure 1 and Figure 2 the first matching structure 140 provided on the outer wall surface of the plug-in part 120 is a matching groove, the second matching structure on the inner wall surface of the plug-in space 211 is a matching protrusion, and when the plug-in part 120 is plugged into the plug-in space 211, the first matching structure 140 and the second matching structure 230 match with each other.

[0050] In other embodiments, the first matching structure 140 is a matching protrusion, and the second matching structure 230 is a matching groove, and when the plug-in part 120 is plugged into the plug-in space 211, the first matching structure 140 and the second matching structure 230 match with each other.

[0051] The plug-in part 120 includes a plug-in body 121 and a plug-in sleeve 122, the plug-in body 121 is arranged around the outer circumferential side of the first coupling member 130 and is connected with the seat body 110, the plug-in sleeve 122 is sleeved on the plug-in body 121 and can rotate around its own axis relative to the plug-in body 121, and at least two first matching structures 140 are arranged on the outer wall surface of the plug-in sleeve 122 and are arranged at intervals in the circumferential direction.

[0052] The included angle between the adjacent two first matching structures 140 is an acute angle, and the range of the included angle is 10°-30°, and specifically can be at least one of 12°, 15°, 18°, 20°, 24° and 30°.

[0053] In some embodiments, the included angle between the adjacent two first matching structures 140 can be one of 12°, 15°, 18°, 20°, 24° and 30°, and then the first matching structures 140 are uniformly arranged in the circumferential direction on the outer wall surface of the plug-in sleeve 122, which can reduce the difficulty in processing, and different types of connectors 10 can be distinguished in appearance by color, as shown in Figure 3As shown, the angle between the two adjacent first matching structures 140 in the red connector 10 is 15°, and is uniformly arranged on the outer wall surface of the plug sleeve 122. Similarly, the angle between the two adjacent second matching structures 230 on the inner wall surface of the plug space 211 is also 15°. As shown in FIG. 6B, the angle between the two adjacent first matching structures 140 in the orange connector 10 is 18°, and is uniformly arranged on the outer wall surface of the plug sleeve 122. Similarly, the angle between the two adjacent second matching structures 230 on the inner wall surface of the plug space 211 is also 18°. Figure 4 As shown, the angle between the two adjacent first matching structures 140 in the red connector 10 is 15°, and is uniformly arranged on the outer wall surface of the plug sleeve 122. Similarly, the angle between the two adjacent second matching structures 230 on the inner wall surface of the plug space 211 is also 15°. As shown in FIG. 6B, the angle between the two adjacent first matching structures 140 in the orange connector 10 is 18°, and is uniformly arranged on the outer wall surface of the plug sleeve 122. Similarly, the angle between the two adjacent second matching structures 230 on the inner wall surface of the plug space 211 is also 18°. Figure 5 As shown, the angle between the two adjacent first matching structures 140 in the red connector 10 is 15°, and is uniformly arranged on the outer wall surface of the plug sleeve 122. Similarly, the angle between the two adjacent second matching structures 230 on the inner wall surface of the plug space 211 is also 15°. As shown in FIG. 6B, the angle between the two adjacent first matching structures 140 in the orange connector 10 is 18°, and is uniformly arranged on the outer wall surface of the plug sleeve 122. Similarly, the angle between the two adjacent second matching structures 230 on the inner wall surface of the plug space 211 is also 18°. Figure 6 As shown, the angle between the two adjacent first matching structures 140 in the red connector 10 is 15°, and is uniformly arranged on the outer wall surface of the plug sleeve 122. Similarly, the angle between the two adjacent second matching structures 230 on the inner wall surface of the plug space 211 is also 15°. As shown in FIG. 6B, the angle between the two adjacent first matching structures 140 in the orange connector 10 is 18°, and is uniformly arranged on the outer wall surface of the plug sleeve 122. Similarly, the angle between the two adjacent second matching structures 230 on the inner wall surface of the plug space 211 is also 18°.

[0054] In some embodiments, the angle between the two adjacent first matching structures 140 can be two of 12°, 15°, 18°, 20°, 24° and 30°, for example: the angle between the two adjacent first matching structures 140 on the plug sleeve 122 in one connector 10 is a combination of 12° and 15°, a combination of 12° and 18°, a combination of 12° and 20°, a combination of 12° and 240, a combination of 12° and 30°, a combination of 15° and 18°, a combination of 15° and 20°, a combination of 15° and 24°, a combination of 15° and 30°, a combination of 18° and 20°, a combination of 18° and 24°, a combination of 18° and 30°, a combination of 20° and 24°, a combination of 20° and 30°, a combination of 24° and 30°, etc.

[0055] In some embodiments, the included angle between two adjacent first matching structures 140 can be a combination of three of 12°, 15°, 18°, 20°, 24° and 30°, for example: a combination of 12°, 15°, 18°, a combination of 12°, 15°, 20°, a combination of 12°, 15°, 24°, a combination of 12°, 15°, 30°, a combination of 12°, 18°, 20°, a combination of 12°, 18°, 24°, a combination of 12°, 18°, 30°, a combination of 12°, 20°, 24°, a combination of 12°, 20°, 30°, a combination of 12°, 24°, 30°, a combination of 15°, 18°, 20°, a combination of 15°, 18°, 24°, a combination of 15°, 18°, 30°, a combination of 15°, 20°, 24°, a combination of 15°, 20°, 30°, a combination of 15°, 24°, 30°, a combination of 18°, 20°, 24°, a combination of 18°, 20°, 30°, a combination of 18°, 24°, 30°, a combination of 20°, 24°, 30°, or a combination of four, five or six of 12°, 15°, 18°, 20°, 24° and 30°.

[0056] In other embodiments, in addition to the range of 10°-30° described above, the included angle between two adjacent first matching structures 140 can also be in the range of 30°-50°, specifically one or a combination of two, three or four of 30°, 36°, 40°, 48°, or in the range of 45°-72°, specifically one or a combination of two, three or four of 45°, 54°, 60°, 72°.

[0057] In other embodiments, in addition to the above-mentioned different number of first matching structures 140 provided on the outer surface of the plug-in sleeve 122, different interface shapes of the first matching structure 140 can also be provided on the outer surface of the plug-in sleeve 122, such as square, semicircular, semicircular, triangular, trapezoidal, etc., and at positions on the inner wall surface of the plug-in space 211 corresponding to each first matching structure 140, a second matching structure 230 matching the shape of the first matching structure 140 is provided, which can also achieve the effect of preventing wrong insertion of the socket 100 and the plug 200 in different types of connectors 10.

[0058] In some embodiments, as shown in FIG. 1, the first matching structure 140 provided on the outer surface of the plug-in sleeve 122 can be a semicircular structure, and the second matching structure 230 provided on the inner wall surface of the plug-in space 211 can be a semicircular structure matching the first matching structure 140. Figure 1 and Figure 2As shown, the plug sleeve 122 is sleeved on the plug body 121 and can rotate relative to the plug body 121 around its own axis by 360°. Therefore, when the plug 200 is inserted into the plug space 211, the first matching structure 140 and the second matching structure 230 match with each other, the plug 200 can rotate relative to the plug body 121 by 360°, and the plug body 121 is arranged on the base 110, thereby achieving the effect that the plug 200 rotates relative to the socket 100 by 360°, and the power transmission lines connected with the connector can be effectively prevented from being intertwined with each other.

[0059] The outer wall surface of the plug body 121 is provided with a first limiting part 123, and the inner wall surface of the plug sleeve 122 is provided with a second limiting part matched with the first limiting part 123. When the plug sleeve 122 is sleeved on the plug body 121, the first limiting part 123 and the second limiting part match with each other, thereby limiting the movement of the plug sleeve 122 along the axial direction of the plug body 121.

[0060] The first limiting part 123 includes one of a limiting protrusion and a limiting groove, and the second limiting part includes the other one of the limiting protrusion and the limiting groove.

[0061] In some embodiments, as shown in FIG. 1, the outer wall surface of the plug body 121 is provided with a first limiting part 123, and the inner wall surface of the plug sleeve 122 is provided with a second limiting part corresponding to the first limiting part 123. Figure 1 As shown, the outer wall surface of the plug body 121 is provided with a first limiting part 123, which is a limiting groove. The inner wall surface of the plug sleeve 122 is provided with a second limiting part corresponding to the first limiting part 123, which is a limiting protrusion. During assembly, the plug body 121 and the plug sleeve 122 are connected by interference fit, that is, the plug sleeve 122 is deformed and installed on the plug body 121. After installation, the plug sleeve 122 returns to its original state, and the plug sleeve 122 is sleeved on the plug body 121, thereby limiting the movement of the plug sleeve 122 along its axial direction, so as to prevent the plug sleeve 122 from being pulled out of the socket 100 along the axial direction.

[0062] In some embodiments, as shown in FIG. 1, the outer wall surface of the plug body 121 is provided with a first limiting part 123, and the inner wall surface of the plug sleeve 122 is provided with a second limiting part corresponding to the first limiting part 123.

[0063] The outer wall surface of the plug-in part 120 has a first limiting structure 124, and the inner wall surface of the plug-in space 211 has a second limiting structure matching the first limiting structure 124. When the plug-in part 120 is plugged into the plug-in space 211, the first limiting structure 124 and the second limiting structure match each other to limit the movement of the plug-in part 120 in the axial direction.

[0064] The first limiting structure 124 is a limiting groove extending in the circumferential direction on the outer wall surface of the plug-in part 120, and the second limiting structure includes at least two limiting lugs. The at least two limiting lugs are distributed in the circumferential direction on the inner wall surface of the plug-in space 211, and the limiting lugs are configured to be clamped with the limiting groove.

[0065] In some embodiments, the outer wall surface of the plug-in sleeve 122 in the plug-in part 120 has a first limiting structure 124, which is a limiting groove extending in the circumferential direction on the outer wall surface of the plug-in sleeve 122. The limiting groove can be an annular limiting groove extending around the plug-in sleeve 122, or can be an arc-shaped limiting groove extending only on part of the outer wall surface of the plug-in sleeve 122, as shown in Figure 1 and Figure 2 The first limiting structure 124 is an annular limiting groove extending in the circumferential direction on the outer wall surface of the plug-in sleeve 122, and the second limiting structure includes at least two limiting lugs. The included angle between adjacent two limiting lugs is not equal to the included angle between any two first matching structures 140 on the plug-in sleeve 122. When the plug-in part 120 is plugged into the plug-in space 211, the limiting lugs are clamped with the limiting groove to limit the movement of the plug-in part 120 in the axial direction.

[0066] In some embodiments, as shown in Figure 1 and Figure 2 The second limiting structure can also be a claw-shaped buckle. When the plug-in part 120 is plugged into the plug-in space 211, the first limiting structure 124 and the claw-shaped buckle match each other, the claw-shaped buckle is clamped with the limiting groove, and the movement of the plug-in part 120 in the axial direction is limited.

[0067] The embodiments of the present application also provide an energy storage device, which includes a device body and the above-mentioned connector 10. At least two connectors 10 are distributed on the device body. The included angle between adjacent two first matching structures 140 in different connectors 10 is different, and the included angle between adjacent two second matching structures 230 in each connector 10 matches the included angle between adjacent two first matching structures 140 in the same connector 10.

[0068] In some embodiments, the energy storage device includes, but is not limited to, an energy storage battery, a plurality of connectors 10 can be arranged on the energy storage battery, and the appearance can be distinguished by color, such as red, orange, black, blue, etc. At least two connectors 10 are provided, and the included angle between the adjacent two first matching structures 140 on the socket 100 in the different color connectors 10 is selected to be different values. Similarly, the included angle between the adjacent two second matching structures 230 on the plug 200 in the different color connectors 10 is selected to be different values. The included angle between the two adjacent first matching structures 140 in the socket 100 and the plug 200 in the same color connector 10 is consistent, so that in the energy storage device, only the socket 100 and the plug 200 of the same color can be inserted into each other, and the socket 100 and the plug 200 in the different color connectors 10 cannot be inserted, thereby achieving the effect of inserting the socket 100 and the plug 200 in the different types of connectors in the wrong way.

[0069] In some embodiments, in the energy storage device, the first matching structure 140 is arranged at the position where the plug-in part 120 is first inserted into the plug-in space 211, and the second matching structure 230 is arranged at the position where the plug-in part 120 is first inserted into the plug-in space 211. Therefore, when the socket 100 and the plug 200 in the different color connectors 10 on the energy storage device are inserted in the wrong way, there is no risk of conduction. In addition, the plug-in sleeve 122 is sleeved on the plug-in body 121 and can rotate 360° around its own axis relative to the plug-in body 121. Therefore, the plug 200 in the same color connector 10 on the energy storage device can rotate 360° relative to the socket 100, which can effectively prevent the power transmission lines connected to the connectors 10 in the energy storage device from being entangled with each other.
