[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] like Figure 1As shown, the wiring harness assembly for a new energy charging socket for construction machinery includes an upper cover 6, which is connected to a charging socket housing 5 via a rotating motorized mechanism 7. A sealing ring 4 is provided on the charging socket housing 5, tightly covering the charging socket. Inside the charging socket housing 5, an electronic lock 1 and a high-pressure air pipe 2 are located. The electronic lock 1 is positioned above the negative DC jack of the charging socket, and the high-pressure air pipe 2 is positioned above the electronic lock 1. The charging socket terminals also include a positive DC jack and a grounding PE jack. The positive DC jack is located to the side of the negative DC jack, and the grounding PE jack is located below the positive and negative DC jacks. A liquid-cooled shielded high-voltage cable assembly 3 is connected to the rear of the charging socket housing 5. Because the charging socket terminals are frequently plugged and unplugged, they can become loose and heat up quickly. Using an electronic lock to secure the charging socket terminals prevents loosening and poor contact, improves the charging port's anti-interference capabilities, and eliminates safety risks. The high-pressure air pipe 2 increases the internal air pressure of the socket, reduces dust, and helps extend the life of the charging socket assembly.

[0018] One end of the rotating motorized device 7 is fixedly connected to one side of the charging base housing 5 , and the other end is hinged to the edge of the upper cover 6 .

[0019] The inner side of the upper cover 6, that is, the surface that contacts the charging seat shell 5 when the upper cover 6 is buckled, is provided with a protective frame that cooperates with the charging socket, and the protective frame is made of plastic material; when the upper cover 6 is buckled, the protective frame can protect the charging port from dust pollution on the one hand, and on the other hand, it can also play the role of fixing the charging port.

[0020] When the upper cover 6 is buckled, the buckle on one side is buckled together with the buckle at the corresponding position of the charging base shell.

[0021] The outer periphery of the charging seat housing 5 is provided with a connection hole, so that the bolts are fixedly connected to the vehicle body through the connection hole.

[0022] like Figure 2 As shown, the electronic lock 1 includes an upper cover 11, a servo motor 12, a lower cover 14, and a lock shaft 13. The lock shaft 13 is located on one side below the lower cover 14. The servo motor 12 is located between the upper and lower covers 11 and 14. The servo motor 12 is connected to a signal line 15. The electronic lock 1 also includes gears. The servo motor 12 drives the gears to move the key block, which contacts the micro switch to start and stop the servo motor 12.

[0023] like Figure 3As shown, the liquid-cooled shielded high-voltage wire assembly 3 includes a charging terminal 31, one end of which is connected to a liquid-cooled heat conduction device 33. This device is sleeved onto one end of a liquid-cooled high-voltage shielded tube 32, which houses a high-voltage shielded wire 34. This device is connected to the high-voltage shielded wire 34. The liquid-cooled shielded high-voltage wire assembly 3 increases the charging rate of the charging socket, mitigates the effects of temperature increases on current carrying capacity, and enhances shielding anti-interference capabilities. The integrated liquid-cooled shielding design reduces wire storage space and facilitates maintenance.
