Technical Field

[0001] The utility model relates to the technical field of charging sockets, in particular to a car charging socket. Background Art

[0002] A new energy vehicle charging socket is a device used to connect a new energy vehicle charging pile. It is used to complete the power transmission and communication functions between the charging pile and the new energy vehicle. Depending on the charging method and the charging protocol of the connected country or region, new energy vehicle charging sockets are generally divided into two types: DC charging sockets and AC charging sockets.

[0003] During the charging process of new energy vehicles, since the charging socket is often exposed to the outdoor environment, especially in severe weather conditions such as rain and snow, waterproof performance has become one of the important indicators to measure the performance of the charging socket.

[0004] Traditional new energy vehicle charging sockets have certain limitations in terms of waterproof design. First, the structural design of the socket often ignores the importance of waterproof performance, which makes it easy for rainwater to penetrate through the gaps or interfaces of the socket, causing internal circuit short circuits or damage, thereby affecting the normal charging process. Secondly, although some charging sockets have adopted certain waterproof measures, due to the low waterproof level or unreasonable waterproof design, they still cannot effectively meet the waterproof needs under extreme weather conditions. Utility Model Content

[0005] The utility model aims at the technical problems existing in the prior art and provides a car charging socket to solve the problem that the charging socket structure has poor waterproof performance and is easy to cause environmental rainwater to penetrate.

[0006] The utility model solves the above-mentioned technical problems with the following technical solutions: a car charging socket, comprising a fixing seat and a terminal fixing head with a charging terminal installed inside, the fixing seat being provided with a terminal extension hole which can be docked with the terminal fixing head; the fixing seat being provided with a lower protective rib which fully surrounds the terminal extension hole along the outer opening of the terminal extension hole.

[0007] On the basis of the above technical solution, the present invention can also be improved as follows.

[0008] Furthermore, the fixing seat forms a fully surrounding upper protective rib along the upper part of the lower protective rib, and a charging gun positioning groove is formed in the upper protective rib.

[0009] Furthermore, a water accumulation groove is provided on the bottom wall of the charging gun positioning groove.

[0010] Furthermore, the upper protective rib is provided with a drainage hole which is horizontally connected to the water trough.

[0011] Furthermore, a drainage channel extending to the outside of the terminal fixing head is also provided at the bottom of the terminal fixing head.

[0012] Furthermore, a sealing ring is provided at the connection between the fixing seat and the terminal fixing head.

[0013] Furthermore, the inner ring of the sealing ring is formed with two spaced water-retaining protrusions inwardly.

[0014] Furthermore, the fixing seat is also provided with an electronic lock rod hole connected to the charging gun positioning groove.

[0015] Furthermore, a fixing plate is provided outside the terminal fixing head, and an assembly opening adapted to the fixing plate is provided on the fixing seat.

[0016] Furthermore, the fixing plate is fixed in the assembly opening of the fixing seat by means of screws.

[0017] Moreover, compared with the prior art, the car charging plug provided by the utility model has at least the following advantages:

[0018] Beneficial effects:

[0019] 1) The lower and upper protective ribs together form a complete waterproof barrier, effectively preventing rain, dust and other external pollutants from entering the socket, protecting the charging terminals and their circuits. This design not only improves the waterproof level of the charging socket, but also enhances the durability and service life of the equipment.

[0020] 2) The water storage tank in the charging gun positioning groove can collect rainwater or other liquids that enter, preventing them from directly contacting the key components inside the charging gun or socket. The drainage hole horizontally connected to the water storage tank can drain the accumulated water in time, keep the charging gun positioning groove dry, and prevent the accumulated water from interfering with or damaging the charging process.

[0021] 3) The drainage channel at the bottom of the terminal fixing head can discharge the liquid that accidentally enters the terminal fixing head, preventing the internal circuit or charging terminal from being damaged by moisture, thereby ensuring the safety and stability of the charging process.

[0027] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0028] It should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrally formed structure. For ordinary technicians in this field, the specific meanings of such terms in this patent can be understood according to specific circumstances.

[0029] like Figure 1 and Figure 2 As shown, the automobile charging socket of the utility model comprises a fixing seat 1 and a terminal fixing head 2 with a charging terminal installed inside, and the fixing seat 1 is provided with a terminal extension hole 1.1 which can be connected with the terminal fixing head 2; the fixing seat 1 is formed with a lower protective rib 3 which fully surrounds the terminal extension hole 1.1 along the outer opening of the terminal extension hole 1.1.

[0030] When the car needs to be charged, firstly, the charging head of the charging gun is connected to the charging terminal on the terminal fixing head 2. This connection process is achieved through the terminal extension hole 1.1 to ensure the electrical connection between the charging gun and the socket.

[0031] The lower protective rib 3 provides physical protection for the terminal extension hole 1.1, preventing dust, moisture or other debris from entering the hole, thereby protecting the charging terminal from contamination or damage.

[0032] As an implementation mode, the fixing seat 1 forms a fully surrounding upper protective rib 4 above the lower protective rib 3 , and a charging gun positioning groove 4 . 1 is formed in the upper protective rib 4 .

[0033] The upper protective rib 4 and the charging gun positioning groove 4.1 therein work together to provide a stable and accurate positioning point for the charging gun, which helps to ensure the correct connection between the charging gun and the charging terminal, while also reducing the risk of accidental movement or falling off during charging.

[0034] By designing two layers of upper and lower protective ribs, the charging head can be quickly positioned, and the notification can prevent environmental rainwater from directly penetrating into the conductive position of the terminal and causing a short circuit. This car charging socket not only improves the stability and safety of the charging process, but also increases the durability and service life of the equipment.

[0035] As an implementation method, a water collection groove 4.2 is provided on the bottom wall of the charging gun positioning groove 4.1. When rainwater or other liquids accidentally enter the charging gun positioning groove 4.1, the water collection groove 4.2 is designed to collect the liquids and prevent them from directly contacting the key components inside the charging gun or the socket.

[0036] In addition, the upper protective rib 4 is also provided with a drainage hole 4.3 which is in horizontal communication with the water sump 4.2. The liquid in the water sump 4.2 can be discharged through the drainage hole 4.3 which is in horizontal communication with the water sump, thereby keeping the charging gun positioning groove 4.1 dry and preventing the accumulated water from interfering with or damaging the charging process.

[0037] As an implementation manner, a drainage channel 2.1 extending to the outside of the terminal fixing head 2 is further opened at the bottom of the terminal fixing head 2.

[0038] The drainage channel 2.1 at the bottom of the terminal fixing head 2 is designed to drain the liquid when rainwater or other liquid accidentally enters the interior of the terminal fixing head, so as to prevent the internal circuit or charging terminal from being damaged by moisture.

[0039] Specifically, a sealing ring 5 is also installed at the connection between the fixing base 1 and the terminal fixing head 2. The sealing ring 5 installed at the connection between the fixing base 1 and the terminal fixing head 2 plays an important sealing role. This can prevent moisture, dust or other debris from entering the socket through the connection, ensuring the safety of the internal circuit and the charging terminal.

[0040] The inner ring of the sealing ring 5 is formed with two spaced water-retaining protrusions inwardly to ensure the sealing performance.

[0041] As an implementation mode, the fixing seat 1 is further provided with an electronic lock rod hole 1.2 which is connected to the charging gun positioning groove 4.1.

[0042] The electronic lock rod hole 1.2 opened in the fixing seat 1 and connected to the charging gun positioning groove 4.1 is used to install the electronic lock rod. The electronic lock rod is part of the charging gun locking mechanism. When the charging gun is inserted and properly docked, the electronic lock rod can extend and lock the charging gun to prevent it from being accidentally pulled out, ensuring the safety and stability of the charging process.

[0043] As an implementation manner, a fixing plate 6 is disposed outside the terminal fixing head 2 , and an assembly opening 1 . 3 adapted to the fixing plate 6 is opened on the fixing seat 1 .

[0044] Specifically, the fixing plate 6 is fixed in the assembly opening 1.3 of the fixing seat 1 by means of screws.

[0045] The terminal fixing head 2 is fixedly connected to the assembly opening 1.3 of the fixing seat 1 through the fixing plate 6 outside thereof, and the connection is firmly secured by screws. This connection method is not only simple and convenient, but also provides sufficient stability to prevent the terminal fixing head 2 from moving or loosening during charging.
