[0041] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0042] In the description of the present utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present utility model. In addition, the terms "first", "second", "third", "fourth", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0043] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0044] See also Figures 1 to 7 The utility model discloses a waterproof socket, including an electrical terminal 1 and a socket body 2. The socket body 2 is a centrally-through structure, in which a first convex ring 3 is arranged. The first convex ring 3 divides the centrally-through structure into a first space 21 and a second space 22. The electrical terminal 1 can be detachably installed in the socket body 2 and passes through the first space 21 and the second space 22. The inner wall of the first convex ring 3 abuts against the outer wall of the electrical terminal 1. A detachable assembly structure is used between the electrical terminal 1 and the socket body 2, which is convenient for disassembly and assembly and helps with later maintenance.

[0045] In this embodiment, the power terminal 1 is provided with a second convex ring 4, which is limited to the first space 21 and the outer wall of the second convex ring 4 abuts the inner wall of the first space 21; a first sealing ring 9 is provided between the first convex ring 3 and the second convex ring 4, and specifically, the first sealing ring 9 abuts the first convex ring 3, the second convex ring 4, the outer wall of the power terminal 1 and the inner wall of the socket body 2, so that the first sealing ring 9 forms a plane seal between the socket body 2 and the power terminal 1. The socket body 2 is provided with a mounting platform 7 on the outside, and a second sealing ring 10 is provided on the side of the mounting platform 7 close to the first space. The socket is inserted into the energy storage box 13, and the surface of the energy storage box 13 is tightly attached to the mounting platform 7. There is coolant in the energy storage box 13. In order to prevent the coolant from flowing out of the gap and causing damage to the equipment, a second sealing ring 10 is provided at the place where the mounting platform 7 and the energy storage box 13 are attached, which effectively seals and prevents the coolant from flowing out.

[0046] Since the present embodiment adopts a planar sealing method, it is only necessary for the first sealing ring 9 to respectively abut against one end face of the first convex ring 3, one end face of the second convex ring 4, the outer wall of the electrical terminal 1 and the inner wall of the socket body 2, so that the second sealing ring can be tightened to close the sealing gap. Therefore, the present application does not have high requirements on the size of the sealing ring and the assembly is relatively simple.

[0047] In this embodiment, if Figure 2As shown, a first limiting groove 11 is provided on one side of the first convex ring 3 close to the first space 21, and a first sealing ring 9 is installed in the first limiting groove 11. The power terminal 1 fits tightly with the socket body 2, and the first sealing ring 9 is arranged in the first limiting groove 11. Since the first sealing ring 9 abuts against the first convex ring 3, the second convex ring 4, the inner wall of the socket body 2 and the outer wall of the power terminal 1, a planar sealing structure is formed inside the power terminal 1 and the socket body 2; since the first sealing ring 9 is interference fit with the side wall of the first convex ring 3, the side wall of the second convex ring 4, the inner wall of the socket body 2 and the outer wall of the power terminal 1 adjacent to the first sealing ring 9, the first sealing ring 9 can better seal the gap between the socket body 2 and the power terminal 1. Compared with the existing side sealing method, the waterproof socket of the utility model can reach the IP68 waterproof grade, that is, it can achieve a long-term sealing effect, and the sealing effect is better.

[0048] In this embodiment, a plurality of notches 401 are provided on the outside of the second convex ring 4, and a limiting portion 201 corresponding to the notches 401 is provided in the first space 21. The notches 401 and the limiting portion 201 have cross-sectional shapes and sizes that match, so that when the electrical terminal is inserted into the socket body 2, the electrical terminal 1 will not rotate in the socket body 2, and is more stable. In this embodiment, the shape of the second convex ring 4 of the electrical terminal 1 is not recommended to be a perfect circle that can rotate around the center, and the preferred shapes include but are not limited to quadrilaterals and ellipses, so that the structure is more solid.

[0049] In this embodiment, the waterproof socket further comprises a socket end cover 5, which is detachably connected to the front end of the socket housing; the front end of the socket end cover 5 is provided with an end cover opening 501, and the socket end cover 5 is sleeved on the front end of the power terminal 1 and the power terminal 1 is detachably fixed in the socket body 2 through the socket end cover 5. The socket end cover 5 can form a detachable installation between the power terminal 1 and the socket body 2, the power terminal 1 is inserted into the socket body 2, and the end cover opening 501 of the socket end cover 5 passes through the head of the power terminal 1. Specifically, the socket end cover 5 is provided with a fixing portion 502, and the socket body 2 is provided with a fixing member 202 matching the fixing portion 502, and the fixing member 202 of the socket body 2 is engaged with the fixing portion 502 and detachably connected to the socket end cover. When the power terminal 1 is inserted into the socket body 2, the end cover opening 501 of the socket end cover 5 passes through the head end of the power terminal 1. At the same time, the fixing portion 502 and the fixing member 202 are engaged with each other, so that the socket end cover 5 is installed at the front end of the socket body 2, and the power terminal 1 and the socket body 2 are loosened or fall off, making the structure more solid.

[0050] Furthermore, a limiting strip 203 is provided at the front end of the socket body 2, and a matching second limiting groove 503 is provided at the socket end cover 5 corresponding to the socket body 2. The limiting strip and the second limiting groove 503 are limited, so that the socket end cover 5 is more firmly installed at the front end of the socket body 2 and is not easy to rotate or shift.

[0051] In this embodiment, the mounting platform 7 is provided with a mounting groove 701, and the second sealing ring 10 is arranged in the mounting groove 701; specifically, Figure 5 , Figure 7 As shown, the mounting platform 7 is arranged on the outside of the socket body 2, and the socket is inserted into the energy storage box 13. The mounting platform 7 is arranged on the outside of the socket body 2 and can fit with the energy storage box 13. A gap will be generated between the surface of the energy storage box 13 and the mounting platform 7. There is coolant in the energy storage box 13, so the socket is in a liquid environment for a long time. In order to prevent the coolant from flowing out of the gap, a second sealing ring 10 is provided at the connection between the mounting platform 7 and the outer wall of the energy storage box 13. At the same time, a mounting groove 701 for placing the second sealing ring 10 is provided on the mounting platform 7 to prevent the second sealing ring 10 from deflecting or loosening, and the sealing effect is better.

[0052] In this embodiment, an anti-contact cap 6 is provided at the tail end of the power terminal 1 to prevent the staff from accidentally touching the inside of the socket and causing electric shock.

[0053] In addition, if Figure 6 , Figure 7 As shown, the embodiment of the utility model also provides a new energy connector including the waterproof socket, wherein the plug 12 is connected to the rear end of the waterproof socket 14, and the plug 12 and the waterproof socket 14 together form a connector. The plug 12 also includes components such as cables connected to the waterproof socket 14. When in use, the positive energy storage box and the negative energy storage box are respectively connected to a connector, and the two connectors are associated to generate electricity.

[0054] Since the connection method of the power terminal 1 and the socket body 2 in some existing sockets is one-piece injection molding, the one-piece injection molding structure cannot be installed with a sealing ring, and the waterproof performance is poor; the structure of some assembled sockets is relatively complex and difficult to disassemble, and the sealing ring ages with the use time, and the waterproof effect is weakened. Therefore, the utility model sets the connection between the plug 12 and the waterproof socket 14 as a detachable assembly method, and the first sealing ring 9 and the second sealing ring 10 age with the time, so that the sealing effect is weakened. When the sealing ring or some parts are damaged, since the parts between the waterproof socket 14 and the plug 12 are assembled and connected, it is convenient to disassemble and replace, and easy to repair.

[0055] The components of the utility model are connected by means of snap-fit ​​and position limiting assembly, and the structure is simple. When an abnormality occurs, the components are easy to disassemble and replace.

[0056] In addition, in the prior art, a side sealing structure is usually used inside the power terminal 1 and the socket body 2. The side sealing structure has high requirements on the size of the first sealing ring 9. If the first sealing ring 9 is slightly wider or narrower, it will lead to poor assembly. In addition, the waterproof level of the prior art can usually only reach IP67, and IP67 can only meet the requirement of short-term immersion. However, in the utility model, a first sealing ring 9 is arranged between the first convex ring 3 and the second convex ring 4. The first sealing ring 9 is interference fit with the side wall of the first convex ring 3, the side wall of the second convex ring 4 and the inside of the socket body 2 to form a planar sealing structure, so that the socket of the utility model can reach the waterproof level of IP68 and has better sealing.

[0057] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
