Technical Field

[0001] This utility model relates to the field of socket terminal technology, and in particular to a vehicle charging socket terminal. Background Technology

[0002] When charging new energy vehicles, a charging gun is typically used to connect to the vehicle's charging port to transmit power and charge the vehicle.

[0003] A common charging structure typically involves a charging gun with pin terminals and a vehicle charging port with a socket terminal. By plugging the two together, charging can be achieved.

[0004] Each time the charging pin is inserted into the socket terminal, the socket terminal is subjected to an impact force. In addition, during the daily driving of the car, it is affected by factors such as bumps. Over time, the existing socket terminal is prone to shaking, which can lead to internal circuit breakage or even short circuit, thus creating a safety hazard. Utility Model Content

[0005] The purpose of this utility model is to solve the technical problem that existing plug terminals are prone to shaking, and to propose a vehicle charging plug terminal.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A vehicle charging socket terminal includes a metal cylinder, one end of which is integrally formed with a metal sheet; an injection-molded shell is fixedly connected to the metal cylinder.

[0008] Preferably, the metal cylinder is provided with an injection hole, and the injection-molded shell passes through the injection hole.

[0009] Preferably, the injection holes are designed in two sets.

[0010] Preferably, a threaded ring is fixedly connected to the injection-molded shell.

[0011] Preferably, the injection-molded shell is provided with a slot, and the threaded ring is fixed in the slot.

[0012] Preferably, the metal cylinder is provided with a sealing plug; the sealing plug is located between the injection-molded shell and the metal sheet.

[0014] Preferably, the metal cylinder has a strip groove on the side away from the metal sheet.

[0015] Preferably, a collar is fitted onto the end of the metal cylinder away from the metal sheet.

[0016] Preferably, a sleeve is fixedly connected to the side wall of the metal cylinder away from the metal sheet.

[0017] Compared with the prior art, the present invention provides a vehicle charging socket terminal, which has the following advantages:

[0018] 1. The vehicle charging socket terminal uses an injection molding process to fix the injection molded shell and the metal cylinder together, which makes the two firmly fixed together, improves the stability, and prevents the metal cylinder from accidentally shaking after being fixed by the injection molded shell. This avoids the safety hazards of open circuit or even short circuit during long-term use.

[0019] 2. The vehicle charging socket terminal is made by stamping one end of a metal cylinder to form a sheet metal plate. Then, the connecting wires inside the vehicle are fixed to the metal plate by ultrasonic welding, which improves the firmness of the connection, prevents accidental detachment, and further avoids the safety hazards of open circuit or even short circuit.

[0020] 3. The vehicle charging socket terminal uses an injection molding hole design to integrate the injection molded shell into the metal cylinder, making the metal cylinder and the injection molded shell a single unit, improving the sturdiness and preventing the metal cylinder from shaking.

[0021] 4. After the injection-molded shell of the vehicle charging socket terminal enters the metal cylinder through the injection hole, it is in contact with the sealing plug, which can also protect the sealing plug and prevent the pin from touching the sealing plug when the pin is inserted, thus avoiding a decrease in sealing performance.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0030] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] Example:

[0032] like Figures 1-6 A vehicle charging socket terminal includes a metal cylinder 1, one end of which is open to form a socket, and the other end of which is integrally formed with a metal sheet 101. Both the metal cylinder 1 and the metal sheet 101 are made of copper and are formed by winding and stamping a single sheet of copper. The connection point after winding and stamping is then welded. Figure 6 Welding is performed in area 7 of the welding zone to improve overall strength.

[0033] A plastic injection molded shell 2 is fixedly connected to the metal cylinder 1. The injection molded shell 2 is made of plastic and is fixed to the metal cylinder 1 using an injection molding process.

[0034] The vehicle charging socket terminal is fixed to the designated position of the vehicle charging port on the vehicle via the injection-molded shell 2. The connecting wires inside the vehicle are ultrasonically welded to the metal sheet 101 to achieve circuit connection.

[0035] During charging, the pin terminals on the charging gun can be inserted into the metal cylinder 1 to establish a connection.

[0036] The injection molding process is used to fix the injection shell 2 and the metal cylinder 1 together, which strengthens the stability and prevents the metal cylinder 1 from shaking accidentally after being fixed by the injection shell 2. This avoids the safety hazards of open circuit or even short circuit during long-term use.

[0037] At the same time, one end of the metal cylinder 1 is stamped to form a sheet metal 101. Then, the connecting wires inside the vehicle are fixed to the metal 101 by ultrasonic welding to improve the firmness of the connection, prevent accidental detachment, and further avoid the safety hazards of open circuit or even short circuit.

[0038] like Figure 3 , Figure 5 , Figure 6 The metal cylinder 1 is provided with injection holes 201. The injection holes 201 are designed in two sets, and the two sets of injection holes 201 are designed opposite each other. That is to say, the two sets of injection holes 201 are evenly distributed around the circumference of the metal cylinder 1.

[0039] The injection-molded shell 2 penetrates the injection hole 201, that is to say, as Figure 3 During the injection molding process, the injection shell 2 enters the interior of the metal cylinder 1 through the injection hole 201.

[0040] The design of the injection hole 201 allows the injection shell 2 to be integrated into the metal cylinder 1, making the metal cylinder 1 and the injection shell 2 a single unit, thus improving the stability and preventing the metal cylinder 1 from shaking.

[0041] like Figures 1-3 A threaded ring 4 is fixedly connected to the injection-molded shell 2, and the outer wall of the threaded ring 4 is provided with a threaded groove.

[0042] The injection-molded housing 2 is connected to other parts of the vehicle via the threaded ring 4.

[0043] like Figure 5 The injection-molded shell 2 is provided with a slot 401, and the threaded ring 4 is fixed in the slot 401.

[0044] The threaded ring 4 is engaged in the slot 401, which improves the firmness of the threaded ring 4 relative to the injection molded shell 2.

[0045] like Figure 3 The metal cylinder 1 is equipped with a sealing plug 3, which is made of rubber; the sealing plug 3 is located between the injection-molded shell 2 and the metal sheet 101.

[0046] The two ends and side walls of the sealing plug 3 are tightly attached to the inner walls of the injection-molded shell 2 and the metal cylinder 1, respectively, to achieve a sealing effect and prevent external moisture from entering the car through the metal cylinder 1.

[0047] At the same time, after the injection-molded shell 2 enters the interior of the metal cylinder 1 through the injection hole 201, it comes into contact with the sealing plug 3, which can also protect the sealing plug 3 and prevent the pin from touching the sealing plug 3 when inserting the pin, thus preventing a decrease in sealing performance.

[0048] like Figure 3 , Figure 4 , Figure 6The end of the metal cylinder 1 away from the metal sheet 101 is provided as an outward opening 501, and the outward opening 501 is in the shape of a trumpet that expands outward.

[0049] The design of the outwardly enlarged horn-shaped opening 501 facilitates easier insertion of the pin terminals inside the charging gun.

[0050] like Figure 6 A strip groove 5 is provided on the side of the metal cylinder 1 away from the metal sheet 101.

[0051] The strip groove 5 is designed in multiple groups, with a quantity of 8-20 groups. It is evenly distributed around the circumference of the side wall of the metal cylinder 1, so that the end of the metal cylinder 1 away from the metal sheet 101 becomes a multi-group strip shape.

[0052] When the pin terminal is inserted, the strip-shaped metal cylinder 1 is slightly deformed outward under the action of the strip groove 5, so as to ensure that it is tightly attached to the pin terminal.

[0053] A collar 502 is fitted onto the end of the metal cylinder 1 away from the metal sheet 101. The collar 502 is made of metal, such as copper or stainless steel.

[0054] The collar 502 serves as a limit to prevent the metal cylinder 1, which is strip-shaped, from deforming excessively outwards and becoming unable to return to its original shape when the pin terminals are not inserted correctly.

[0055] A sleeve 6 is fixedly connected to the side wall of the metal cylinder 1 away from the metal sheet 101. The sleeve 6 is made of stainless steel and serves to protect the metal cylinder 1, because copper is soft and easily scratched.

[0056] The sleeve 6 is designed with both ends open, and is directly fitted onto the metal cylinder 1. It is located at one end of the outward opening 501 and is designed to conform to the shape of the outward opening 501 to ensure that the sleeve 6 and the metal cylinder 1 are tightly attached.

[0057] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
