Problems solved by technology

[0004] The existing mainstream socket grounding method is to peel the shielding layer through the cable outside the socket, connect the shielding layer to the small square cable, and then connect the small square cable to the body ground; this mainstream socket grounding method The disadvantage is that it is necessary to use an additional structure for protection at the cable stripping place, and the protection is difficult to achieve the effect of IP67; in addition, because the protection structure is complicated, the operation and assembly are relatively poor, so it is necessary to design a A new product to meet the actual needs of use

Abstract

The invention relates to a charging socket internally equipped with a shielding layer, and particularly relates to a socket for charging of an electric automobile. The socket equipped with the shielding layer for internal grounding comprises a front shell, a rear shell, a first terminal module, a second terminal module and a shielding grounding connection module. The first terminal module and thesecond terminal module which stretch forward are arranged on the rear shell. The front end of the rear shell is provided with the corresponding front shell. The front shell is provided with jacks forplugging of the first terminal module and the second terminal module. The first terminal module and the second terminal module are connected through the shielding grounding connection module. The front shell and the rear shell are connected through bolts or buckles. The first terminal module comprises signal terminals, a grounding terminal and AC high voltage terminals. One side of the grounding terminal is provided with a pair of signal terminals with the grounding terminal acting as the center of circle, and the external side of the grounding terminal is also provided with one or two pairs of AC high voltage terminals.

Description

technical field [0001] The invention relates to a charging socket provided with a shielding layer inside, in particular to a charging socket for electric vehicles. Background technique [0002] In the existing electric vehicle charging socket, in order to ensure that the charging socket has good electromagnetic compatibility, it is necessary to carry out electromagnetic shielding treatment on the charging socket to prevent harmful electromagnetic interference from the high-voltage cable. [0003] At present, most OEMs require that the shield be grounded at the connector end, and the socket end does not need to be grounded; however, some OEMs require both ends to be grounded, which requires grounding at the socket end in addition to the connector end. [0004] The existing mainstream socket grounding method is to peel the shielding layer through the cable outside the socket, connect the shielding layer to the small square cable, and then connect the small square cable to the ...
