Description

Technical Field

[0001] This utility model relates to the technical field of vehicle charging sockets, and in particular to a front-draining socket housing and a car charging socket. Background Technology

[0002] With the rapid development of new energy technologies, electric vehicles are becoming increasingly widely used. The main function of an electric vehicle charging socket is to establish an electrical connection between the charging gun and the vehicle's charging connector, ensuring stable charging operations. To guarantee the stability of the charging process, automakers are paying increasing attention to the structure of electric vehicle charging sockets. The drainage or waterproofing function of the charging socket is crucial for ensuring electrical safety and extending its lifespan, especially in humid environments or outdoor use.

[0003] Traditional charging sockets for charging stations mostly use bottom drainage, with the drainage port being a through hole at the bottom of the socket. This makes it impossible to guide the flow of liquid, allowing leaked liquid to directly enter the vehicle's interior, making complete drainage and preventing leakage difficult. Car charging sockets are typically embedded in the vehicle's body at the rear, with the front exposed for electrical connection. However, most existing electric vehicle sockets use a rear-drainage design. For example, patent application CN210272783U discloses an electric vehicle drainage port-type charging socket. This involves adding a drainage port and pipe to the front mounting plate to collect leaked liquid from the socket, then draining the liquid out of the vehicle through a connected hose. This design suffers from the problem of liquid easily leaking to the rear of the socket, posing a significant risk of damaging the vehicle's electrical connections. Furthermore, it requires regular inspection and maintenance by the customer, involves numerous parts in the connection structure, has multiple installation steps, and poor product applicability. Utility Model Content

[0004] The purpose of this invention is to address the problem that existing car charging sockets have a high risk of liquid leakage at the rear end, which could damage the electrical connections inside the vehicle. This invention provides a front-draining socket housing and a car charging socket.

[0005] To achieve the objective of this utility model, one solution provided by this utility model is as follows:

[0006] A front-draining socket housing includes: a housing body and a protective wall; an insulator for a car charging socket is embedded in the housing body; the insertion end of the insulator extends towards the front end of the housing body;

[0007] The protective wall surrounds the outside of the insertion end of the hole insulator, forming a cavity for insertion between the insertion end and the protective wall; one end of the protective wall is integrally formed and fixedly connected to the front plate surface of the shell body, and the other end of the protective wall extends toward the front end of the shell body;

[0008] A first drainage channel is provided at the connection between the protective wall and the front plate, thereby enabling the insertion cavity to be connected to the outside of the protective wall.

[0009] The present invention, by setting the plug-in end of the shell body, the hole insulator, and the protective wall and their orientation, forms a plug-in cavity between the plug-in end and the protective wall. Furthermore, by opening a first drainage channel at the connection between the protective wall and the front panel, the plug-in cavity and the outer side of the protective wall can be connected. If rainwater or other liquids enter the plug-in cavity of the charging socket, under the simple condition that the part of the shell body with the first drainage channel is tilted towards the ground, the liquid or water in the plug-in cavity can be automatically discharged to the outside of the vehicle body by gravity. Due to the overall embedding of the hole insulator, the densely packed terminal circuits on the rear panel of the shell body are kept as much as possible at the front end of the shell body. Compared with traditional or existing rear-end drainage, this reduces the risk of liquid leakage at the rear of the socket damaging the electrical connections inside the vehicle, enhancing waterproof safety. Moreover, at the rear of the shell body, no drainage components such as hoses are needed to drain the liquid out of the vehicle, reducing the frequency of user inspection and maintenance, and improving the applicability, convenience, and reliability of the charging socket.

[0010] Preferably, in the front-draining socket housing of the present invention, the first drainage channel has a guide port on the inner side of the protective wall facing the plug end, and the drainage port on the outer side of the first drainage channel extends towards the protective wall.

[0011] As a preferred embodiment of this utility model, by having the guide port extend towards the plug-in end and the drain port extend towards the protective wall, water or liquid in the plug-in cavity can more easily enter from the guide port when the shell body is tilted towards the first drain channel, and then be discharged from the drain port in the direction extending towards the protective wall. Compared with the traditional drain scheme where the bottom is perpendicular to the protective wall or the bottom is the drain outlet, the drain port will not directly contact the vehicle body surface, allowing the rear half of the shell body to contact the vehicle body. There is no liquid or water outflow channel between the drain port and the vehicle body, further reducing the possibility of liquid leaking into the vehicle when draining, and further reducing the risk of liquid seeping at the rear end of the socket and damaging the electrical connection inside the vehicle.

[0012] Preferably, in the front-drainage socket housing of the present invention, the portion of the first drainage channel near the drainage port extends along the outer side wall of the protective wall.

[0013] As a preferred embodiment of this utility model, by setting the portion of the first drainage channel near the drainage port to extend along the outer side of the protective wall, the liquid or water can be guided by the outer side of the protective wall during the drainage process, thereby reducing the possibility of water or liquid flowing back from the first drainage channel and further improving the reliability of drainage.

[0014] Preferably, in the front-drainage socket housing of this utility model, the inner wall of the first drainage channel is inclined from the guide port to the drainage port.

[0015] As a preferred embodiment of this utility model, by setting the inner wall of the first drainage channel inclined from the guide port to the drainage port, it is beneficial for water or liquid to flow out to the drainage port by its own gravity, thereby further enhancing the reliability of drainage.

[0016] Preferably, in the front-drainage socket housing of this utility model, the drain port is an ellipse with its long side parallel to the protective wall.

[0017] As a preferred embodiment of this utility model, by setting the drain outlet of the aforementioned shape, it is beneficial for the liquid to be discharged along the arc-shaped elliptical edge, reducing the resistance of the liquid flowing out from the first drain channel, and further improving the reliability of the drain.

[0018] Preferably, in the front-draining socket housing of this utility model, a first sealing ring is provided at the joint between the hole insulator and the housing body.

[0019] As a preferred embodiment of this utility model, by providing a first sealing ring at the joint between the hole insulator and the shell body, the possibility of leakage due to excessive liquid or water in the insertion cavity not being drained in time can be avoided. Furthermore, by draining water or liquid to the outside of the vehicle body, the possibility of water or liquid entering the vehicle body and damaging electrical connectors is further reduced, thereby enhancing the water protection performance of the front-draining socket shell.

[0020] Preferably, in the front-draining socket housing of this utility model, the protective wall includes two walls respectively disposed on the outside of the two sets of hole insulators; a second drainage channel is opened between the two protective walls, thereby connecting the two plug-in cavities formed by the two protective walls respectively.

[0021] As a preferred embodiment of this utility model, based on the ability to connect two sets of connection terminals of the car charging socket, a second drainage channel is provided between the two protective walls. This allows the accumulated liquid in the two connection cavities to be connected through the second drainage channel, thereby accelerating the discharge of the accumulated liquid, further improving the drainage efficiency and enhancing the performance.

[0022] Preferably, in the front-drainage socket housing of this utility model, one of the two protective walls has the first drainage channel.

[0023] As a preferred embodiment of this utility model, by opening a first drainage channel in one of the two protective walls, it is beneficial to the orientation of the car charging socket. For example, the part of the shell body with the first drainage channel is located at the bottom, which improves the convenience of installation and replacement.

[0024] To achieve the objective of this utility model, another solution provided by this utility model is:

[0025] An automotive charging socket includes: a socket terminal assembly, a hole insulator, a fixing member, and a front-draining socket housing. The socket terminal assembly is used for electrical connection and is inserted into the hole insulator. The hole insulator is embedded in the housing body and fixedly connected. The fixing member is detachably fixed to the rear end of the hole insulator, thereby fixing the socket terminal assembly.

[0026] The car charging socket described in this utility model, based on the front-draining socket housing, not only reduces the risk of liquid leakage at the rear of the socket damaging the electrical connections inside the vehicle and enhances waterproof safety; but also, through the cooperation of the hole insulator, fixing parts and socket terminal assembly, it can further improve the water-proof protection performance and enhance the protective reliability of the car charging socket.

[0027] Preferably, in the car charging socket of this utility model, a second sealing ring is provided at the insertion point of the socket terminal assembly and the hole insulator.

[0028] As a preferred embodiment of this utility model, by setting a second sealing ring, it is possible to effectively prevent liquid from seeping from the hole insulator into the socket terminal assembly. On the basis of drainage through the front-draining socket housing, the insulation protection and water leakage prevention function of the car charging socket are further enhanced, and the protection reliability is improved.

[0029] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0030] 1. The front-mounted drain socket housing is installed and connected according to the orientation and hole insulator. Compared with the traditional or existing rear-mounted drain, it reduces the risk of liquid leakage at the rear of the socket and damage to the electrical connection in the vehicle, and enhances waterproof safety. In addition, at the rear of the housing body, liquid can be discharged out of the vehicle body without the need for draining components such as hoses, reducing the frequency of user inspection and maintenance, and improving the applicability, convenience and reliability of the charging socket.

[0031] 2. The aforementioned car charging socket not only reduces the risk of liquid leakage at the rear end of the socket damaging the electrical connections inside the vehicle and enhances waterproof safety; but also, through the cooperation of the hole insulator, fixing parts and socket terminal assembly, it can further improve the waterproof protection performance and enhance the protective reliability of the car charging socket.

[0042] It should be noted that the hole insulator 13 of the car charging socket can be understood as the hole insulator 13 of a typical car charging socket, which is used to insulate the metal connection terminal from the outside, and plays the role of insulating or sealing the connection terminal; in this utility model, it can be the hole insulator 13 designed according to the shape and requirements of the actual connection terminal, or it can be the hole insulator 13 in Embodiment 2 of this utility model.

[0043] refer to Figure 1 and Figure 2 As shown, the front end of the housing body 11 described in this utility model is understood as the end where the insertion end 131 of the hole insulator 13 is located, the part where the socket and plug of the live connection terminal are inserted into each other, which is usually the part of the housing body 11 that is exposed to the car body.
