Embodiment 1

[0033] 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 1 As 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 end con...

Embodiment 2

[0041] 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 relation...

Embodiment 3

[0044] 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.

[0045] Of course, the present invention can also have other modifications besi...

Abstract

The invention provides a conduction type charging connector for an electric vehicle. The connector comprises a vehicle end connecting part and a charger end connecting part, wherein the vehicle end connecting part comprises an insulating socket structure, the charger end connecting part comprises an insulating plug structure, the plug structure and the socket structure are matched with each other; the plug comprises an earth electrode and a power supply electrode, a charge controlling electrode is also arranged in the plug; a jack which is formed in the socket is matched with the plug electrodes, the heights of the earth electrode, the power supply electrode and the charge controlling electrode decrease in turn. In the invention, an inserting mode is adopted between the vehicle end connecting part and the charger end connecting part, two conductors which are matched with each other and correspond in positions are respectively arranged on the vehicle end connecting part and the chargerend connecting part; by adopting the structure, the charging connector can be directly inserted without an intermediate transition structure, thus the charging connector is convenient to use; each electrode adopts the structure with a certain height difference, thus the connector can be avoided plugging an electric arc during the connecting and separating process, the safety of the operators and vehicles can be ensured and the service life of the connector can be prolonged.

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...
