Problems solved by technology

If adopted Image 6 The 6A connector structure shown is far from meeting the creepage distance requirements
When the existing conventional connector structure is applied to a 10A charging environment, when a large current passes after the male and female are matched, they all face the defect of insufficient creepage distance, which will cause the terminals to spark each other and cannot guarantee the safety of use

Embodiment 1

[0037] This embodiment introduces a DC charging connector, combined with Figure 1 to Figure 3 , the DC charging connector includes an insulating body 1 , a positive terminal 5 , a negative terminal 4 and a signal terminal 3 .

[0038] refer to figure 2 As shown, the insulating main body 1 is cylindrical, and its axial center is provided with a first socket 12, and the outer periphery of the first socket is provided with a second socket 13; one end of the positive terminal 5 is penetrated to the first socket In the groove, the other end extends toward the tail end of the insulating body 1 ; the negative terminal 4 is arranged on the outer periphery of the positive terminal 5 , and the signal terminal 3 is penetrated through the peripheral portion of the insulating body 1 .

[0039] The inner ring side wall and the outer ring side wall of the second socket are respectively provided with contact ports corresponding to the negative terminal 4 and the signal terminal 3, and the ...

Embodiment 2

[0049] Considering that the existing high-current chargers still have the defects of high scrap rate of finished products caused by unreasonable space utilization and difficulty in assembly and welding, this embodiment introduces another method that can ensure the effective distance between different types of terminals. Basically, it can also reduce the difficulty of assembly and welding, and make full use of the DC charging connector in the internal space of the connector.

[0050] combine Figure 1 to Figure 5 , on the basis of Example 1, in this example, such as figure 1 As shown, the negative terminal 4 includes a cable connection end 41, an annular connection portion 42 and a plurality of socket terminals 43, one end of the cable connection end is connected to one side of the ring connection portion, and a plurality of socket ends are distributed and connected to the ring connection portion. Perimeter on the other side.

[0051] combine figure 1 and Figure 4 , the ...

Abstract

The invention discloses a direct current charging connector suitable for large current. The direct current charging connector comprises an insulating main body, a positive terminal, a negative terminal and a signal terminal; the insulating main body is cylindrical, the axis part of the insulating main body is provided with a first plugging groove, and the periphery of the first plugging groove is provided with a second plugging groove; one end of the positive terminal penetrates into the first plugging groove, and the other end of the positive terminal extends towards the tail end of the insulating main body; the negative terminal is arranged on the periphery of the positive terminal, and the signal terminal penetrates through the peripheral part of the edge of the insulating main body; the inner ring side wall and the outer ring side wall of the second plugging groove are respectively provided with contact ports corresponding to the negative terminal and the signal terminal, and the elastic protruding parts of the negative terminal and the signal terminal respectively extend into the second plugging groove from the corresponding contact ports without external force; and the end face of the tail end of the insulating body between the positive terminal and the negative terminal is provided with at least one protruding part or concave part. The creepage distance between the positive terminal and the negative terminal can be increased, so that the direct-current charging connector can be suitable for large-current charging, and the use safety is guaranteed.

Description

technical field [0001] The invention relates to the technical field of new energy vehicle accessories, in particular to a DC charging connector suitable for high current. Background technique [0002] In the face of increasingly serious energy, climate, and environmental problems, the development of new energy vehicles has gradually become the consensus of the world. In recent years, the production and sales of electric vehicles have been increasing year by year, which has also greatly increased the market demand for charging connectors that supply electric vehicle power. [0003] The electric vehicle charging connector generally includes a socket connector (female seat) and a plug connector (male seat). At the same time, in order to realize the management of the charging process, the charging connector is also equipped with terminals for conducting low-voltage signals. Such as Figure 6 In the shown 6A charging connector socket, a positive terminal 01 is set at the center,...
