Embodiment 1

[0027] [0027] Such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 and Figure 14 As shown, this electric vehicle conductive charging connector 1 of the present invention, in this embodiment, the electric vehicle conductive charging connector 1 is used for the on-board charging mode of three-phase alternating current, such as figure 1As shown, the wires in the charging connector are not shown in the figure, and its interface structure is highlighted. The charging connector can be designed in a handle shape, which is easy to hold during use. It includes the vehicle end connection part 31 and the charger end. The connection part 21 and the vehicle end connection part 31 are arranged on the vehicle and are electrically connected to the charging system of the vehicle. The charger end connection part 21 is electrically connected to the charging power source. The charging power source is usually a charger. The ...

Embodiment 2

[0035] [0034] Such as Figure 5 , Figure 6 and Figure 7 , Figure 9 , Figure 10 , Figure 12 , Figure 13 and Figure 14 As shown, the electric vehicle conductive charging connector of this embodiment is used for the on-board charging mode of single-phase alternating current, and it includes a vehicle end connection part 32 and a charger end connection part 22, and the vehicle end connection part 32 is arranged on the vehicle And be electrically connected with the charging device of the vehicle, the charger end connection part 22 is electrically connected with the charging power supply, the vehicle end connection part 32 includes an insulating socket 321 structure, and the charger end connection part 22 includes an insulating plug 221 structure, this embodiment and implementation The difference of Example 1 is that a grounding electrode 51, two power supply electrodes 53 and two charging control electrodes 52 are arranged in the plug 221, and the specific positional ...

Embodiment 3

[0038] [0036] Such as Figure 8 As shown, this embodiment is an improvement on the socket in the socket in Embodiment 1 and Embodiment 2. Specifically, the locking sleeve on the outer periphery of the socket 10 is replaced by a radially telescopic spring 12, and the radially telescopic spring The combination of 12 and the elastic cantilever of the socket realizes the "soft structure" contact. The radially stretchable spring 12 is elastic, and the "pre-deformation" generated in the elastic wall of the socket can generate contact pressure in the radial direction of the socket, thereby realizing Contact compression on the circumferential surface of the post. In the process of joining the post and the socket, a larger contact pressure is realized, the contact resistance is reduced, the characteristic impedance is continuous and uniform, and the intermodulation performance and the plug-in cycle are improved.

[0039] [0037] Of course, the present invention can also have other mo...

Abstract

A conductive charging connector for an electric vehicle, comprising a vehicle end connection portion and a charger end connection portion, the vehicle end connection portion includes an insulating socket structure, the charger end connection portion includes an insulating plug structure, and the plug structure and the socket structure are matched , the plug includes a grounding pole and a power pole, the plug is also provided with a charging control pole, and the socket is provided with a jack to match the plug electrodes, and the heights of the grounding pole, the power pole and the charging control pole decrease in turn. In the present invention, the connecting part of the vehicle end and the connecting part of the charger are connected in a plug-in manner, and the connecting parts of the vehicle end and the connecting part of the charger are respectively provided with corresponding and matched conductors to cooperate. The charging connector can be plugged in directly without intermediate transition structure, and is easy to use. Each electrode adopts a structure with a certain height difference, which eliminates the plugging arc of the connector during engagement and separation, and ensures the safety of operators and vehicles , improve the service life of the connector.

Description

technical field [0001] The present invention relates, in particular, to a charging connector, especially a conductive charging connector under a high current state, especially for use between an electric vehicle and a charging station as well as between the national grid and a charging station, specifically an electric charging connector. Vehicle conductive charging connector. Background technique [0002] The electric vehicle conductive charging connector is an interface electromechanical component specially used to connect and transmit energy and signals. It can be used for the connection between the charging station end and the national grid end and between the vehicle end and the charging station end. connect. In order for the electric vehicle charging connector to effectively transmit energy and signals, its characteristic impedance must match that of the entire connection system. Not only the reflection coefficient and contact loss of the connector itself are required...
