A power battery connector sealing structure

Abstract

The invention discloses a sealing structure of a power battery connector, which comprises a pressing plate, a raised portion and a protrusion, the pressing plate and the connector are respectively attached to the inner and outer walls of a box body, and the raised portion on the pressing plate is Through the wall of the box body and against the first sealing ring on the connector, the bolt passes through the installation through hole on the connector to match the threaded hole on the pressing plate, and the connection between the connector and the pressing plate presses the first sealing ring Closely between the connector and the raised part of the pressing plate, the sealing of the connector is realized. During the connection process between the compression plate and the connector, both sides of the box wall bear the uniform compressive stress provided by the compression plate and the connector, and the compression plate can support the box wall, reducing the stress in the sealing process of the connector The shape of the box is variable, and the sealing of the connector is realized through the cooperation of the first sealing ring and the raised part. The surface flatness of the raised part will not be affected during the mating process of the pressing plate and the connector, thus ensuring the reliability of the seal. sex.

Description

technical field [0001] The invention relates to the technical field of automobile devices, in particular to a sealing structure of a power battery connector. Background technique [0002] In the prior art, the sealing of the new energy vehicle power battery connector is mainly realized by the sealing ring of the connector itself. The connector 01 is directly connected to the box body 02 to compress the sealing ring 03. In order to ensure the sealing of the sealing ring 03, it is necessary to modify the structure of the box body. The surface has high flatness, such as figure 1 As shown, the contact side of the connector 01 and the box body 02 is a planar structure, and the connector 01 and the box body 02 are directly connected by bolts. During the bolt connection process, the surface of the box body is easily deformed, resulting in the flatness of the box body surface. If the requirements cannot be met, the seal between the connector 01 and the box body 02 will fail. [00...

The connector 01 is directly connected to the box body 02 to compress the sealing ring 03. In order to ensure the sealing of the sealing ring 03, the box structure needs to be adjusted. The surface has a high flatness, such as figure 1 As shown, the contact side of the connector 01 and the box body 02 is a planar structure, and the connector 01 and the box body 02 are directly connected by bolts. During the bolt connection process, the surface of the box body is easily deformed, resulting in the flatness of the box body surface. Can not meet the requirements, the seal between the connector 01 and the box 02 is invalid
