[0031] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be described clearly and completely below in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. All other embodiments obtained by the person skilled in the art without creative labor belong to the scope of protection of the utility model.

[0032] According to Figure 1 , Figure 2 , Figure 5 ,Figure 6 、 Figure 8 and Figure 9 As shown, a new integrated charging station includes a socket body 1, a front end of which is provided with a plug-in cavity 101 for docking with a car power gun, and a rear end provided with a loading hole 102 for loading a PE terminal 2, a power terminal 3, and a signal terminal 9. The plug-in area for loading the PE terminal 2, the power terminal 3, and the front end of the signal terminal 9 is accommodated in the plug-in cavity 101;

[0033] a socket rear cover 5, which is disposed at the rear end of the socket body 1 and is detachably connected to the socket body 1 to retain the PE terminal 2, the power terminal 3, and the signal terminal 9 within the socket body 1, and has axially defined ground connection channels 503 and power connection channels 501 corresponding to the connection ends of the PE terminal 2 and the power terminal 3 and used for wiring; and

[0034] The PCBA circuit board 4 is arranged between the socket back cover 5 and the socket body 1, and the elastic terminals 401 connected thereon are in contact with the signal terminals 9 and the PE terminals 2 respectively, and are used to transmit signals and achieve safe grounding, signal reference and stability, electrostatic discharge and electromagnetic compatibility. A pin 404 for transmitting signals outward is provided thereon. The pin 404 is accommodated in the signal connection channel 502 opened on the socket back cover 5 for plugging in. A multi-core plug is matched to the pin 404 to achieve signal communication with the entire vehicle.

[0035] In this embodiment, in order to realize the quick disassembly and assembly of the socket body 1 and the socket back cover 5 , the socket body 1 and the socket back cover 5 are connected by snap fasteners.

[0036] In this embodiment, if Figure 3 、 Figure 4 and Figure 7 As shown, there are preferably two signal terminals 9 and two power terminals 3.

[0037] In this embodiment, in order to further ensure the stability and safety of the signal terminal 9 when plugged in, a signal bracket 8 for holding the signal terminal 9 in the loading hole 102 is detachably provided at the rear end of the socket body 1 .

[0038] The tail of the power terminal 3 can be designed in different forms, such as welding, crimping, screwing, etc.

[0039] In this embodiment, since rainwater often enters the plug cavity 101 when the charging base is outdoors, in order to drain the accumulated water at the mouth of the charging base in time to ensure the safety of the car when charging, the following method is used: Figure 1 As shown, a drain nozzle 10 is connected below the socket body 1 for communicating with the interior of the plug-in cavity 101 and for draining accumulated water.

[0040] In the embodiment, as shown in Figure 1 and Figure 4 The socket body 1 is provided with an electronic lock 11 for locking the charging gun inserted into the socket body 1. If the charging gun is accidentally disconnected during charging, it may cause damage to the charging equipment and the vehicle, and even cause a safety accident. Therefore, the electronic lock 11 can ensure that the charging gun is firmly connected to the charging seat, prevent the charging from being interrupted due to external force collision, pulling and the like, and prevent the charging gun from being maliciously stolen, since the charging gun and the charging cable are usually expensive. The electronic lock 11 can only be unlocked after the charging is completed or through legal authorization, thereby ensuring the safety of the charging equipment.

[0041] The locking portion 113 of the electronic lock 11 is arranged in the plug cavity 101 to match the groove on the charger. The locking portion 113 is provided with a sealing gasket 111 and a sealing gasket bracket 112. The sealing gasket 111 and the sealing gasket bracket 112 are embedded in the socket body 1. The sealing gasket 111 can be used to seal the circumference of the locking portion 113, so that water cannot enter the electronic lock 11 through the locking portion 113 when the locking portion 113 is in operation. The sealing gasket bracket 112 can keep the sealing gasket 111 in the socket body 1.

[0042] In the embodiment, as shown in Figure 5 The PCBA circuit board 4 is provided with a temperature sensor 403. The temperature sensor 403 can be used to monitor temperature changes and prevent overheating, avoid overcooling affecting the charging efficiency, and adjust the charging parameters according to the temperature to improve the charging efficiency and speed.

[0043] In the embodiment, as shown in Figure 5 The PCBA circuit board 4 is provided with a resistor 402 with a resistance value of 2700Ω. In the circuit, since a large current can cause damage to electronic components, it is necessary to limit the size of the current. The resistor can prevent the current from being too large to damage other sensitive components, and can also be used to stabilize the current and adjust the voltage.

[0044] In the embodiment, as shown in Figure 3 The socket rear cover 5 is connected with a power end rear cover 7 sleeved on the power line. The power end rear cover 7 is connected with a rubber part for wrapping the power connection. The rubber part is accommodated in the power connection channel 501. The rubber part can prevent water and moisture from entering the power connection channel 501, and can increase the mechanical strength and toughness of the power line. In a further embodiment, the socket rear cover 5 and the power end rear cover 7 are connected by a buckle. The buckle connection has the characteristics of quick assembly, low cost, compact structure and high reliability.

[0045] In the embodiment, as shown in Figure 4 The PE end rear cover 6 sleeved on the ground wire is connected to the socket rear cover 5, and the socket rear cover 5 is provided with a rubber covering part for wrapping the ground wire, and the rubber covering part is accommodated in the ground connection channel 503.

[0046] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
