Description

Technical Field

[0001] The utility model relates to the field of direct current charging, and more specifically, to a circuit-integrated plug device for a charging gun. Background Art

[0002] A DC charging pile is a device that is fixedly installed outside an electric vehicle, connected to the AC power grid, and directly outputs adjustable DC power to charge the vehicle battery. The DC charging pile has a wide voltage and current adjustment range, high power, and fast charging speed, commonly known as "fast charging".

[0003] The front-end components of the DC charging gun plug generally include a pin insulator, a pin, a pin seal, an insulating cap, and a cable. In the prior art, the ground pin and the connection confirmation pin are generally connected by wiring, which has the problems of messy cables and cumbersome crimping process, greatly increasing the complexity of assembly. Utility Model Content

[0004] The utility model overcomes the shortcomings of the prior art and provides a circuit-integrated plug device for a charging gun, so as to solve the problems of the prior art in terms of wiring connectivity, messy cables, and complicated crimping process.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A circuit-integrated plug device for a charging gun, comprising a pin-rear insulator, a PCB board, a pin assembly, and a sealing ring;

[0007] The PCB board is fixed on the insulator behind the needle;

[0008] The pin assembly is connected to the PCB board;

[0009] The sealing ring is installed on the pin assembly.

[0010] At the front end of the charging gun plug, circuit integration is used instead of wiring to achieve pin interconnection, which reduces the complexity of the cable and saves pin rod material.

[0011] A further technical solution is that the pin assembly includes a ground pin, a main power pin, a charging connection confirmation pin, a communication pin, and a low-voltage auxiliary power pin.

[0012] A further technical solution is that the PCB is fixed to the rear-needle insulator by cross-slot pan head self-tapping screws.

[0013] A further technical solution is that the pin assembly is fixedly connected to the insulator behind the pin.

[0014] Since the insulator behind the needle is made of insulating material and has a certain elasticity, the insulator behind the needle can be processed so that it can fix the pin assembly through deformation, further reducing the use of fixing components.

[0015] A further technical solution is that the sealing ring is installed on the pin assembly through a slot provided on the pin assembly.

[0016] A further technical solution is that the circuit-integrated charging gun plug device further includes an insulating cap;

[0017] The insulating cap is fixed on the main power pin through an inner buckle.

[0018] A further technical solution is that the circuit-integrated charging gun plug device further includes a pogpin terminal;

[0019] One end of the pogpin terminal contacts the pin assembly, and the other end is welded on the PCB board.

[0020] Using pogpin terminals for connection can improve the corrosion resistance, stability and durability of the connection.

[0021] A further technical solution is that the pogpin terminal includes an elbow pogpin terminal and a straight pogpin terminal;

[0022] The ground pin is connected to the PCB board using an elbow pogpin terminal, and the main power pin, charging connection confirmation pin, communication pin, and low-voltage auxiliary power pin are connected to the PCB board through a straight pogpin terminal.

[0023] Compared with the prior art, the utility model has at least the following beneficial effects: the utility model adopts circuit integration instead of wiring to realize the intercommunication of pins, creatively selects straight and elbow forms of pogpin to realize the connection between pins and integrated circuit pcb boards, and reasonably selects elbow pogpin terminals and straight pogpin terminals for connection according to the positional relationship between the pins and the integrated circuit pcb board. This construction method reduces the complexity of the cable, saves pin rod materials, and thus reduces the manufacturing cost. BRIEF DESCRIPTION OF THE DRAWINGS
