Power battery connector protection device

Abstract

The invention discloses a protection device for a power battery connector. The main design idea of ​​the invention is to wrap the plug connector of the power battery, including the socket and the front half of the plug, in the hollow part of the sheath through a semi-cylindrical sheath that is mated and connected with each other. space, and is limited by the front and rear bosses on the connector, specifically, the first boss is in contact with the socket base and the battery pack box, and the second boss is in contact with the locking slider of the plug and the body. Therefore, it can effectively prevent external sand, rainwater, etc. from entering the inside of the connector, and keep the connector end safe and reliable. The invention is not affected by the structure of the battery pack, has universal applicability, and effectively isolates the joint part of the connector from the external space, thereby improving the insulation performance and prolonging the service life.

Description

technical field [0001] The invention relates to the field of new energy vehicles, in particular to a power battery connector protection device. Background technique [0002] With the vigorous promotion and application of new energy vehicles, there are more and more vehicle usage scenarios. In the long-term use process, the battery connector is exposed for a long time. At present, the mainstream connector lacks corresponding protection, and there are problems such as sediment wrapping, which seriously affects the maintenance of the connector and the safety of the whole vehicle. Specifically, as a key component of new energy vehicles, power batteries should be safe and reliable during use, while the connector ends of existing vehicle power batteries (especially new energy commercial vehicles) are almost exposed at the bottom of the frame. Safety protection measures lead to the phenomenon that the battery connector is covered with sediment after a certain period of use, and th...

AI Technical Summary

Problems solved by technology

[0004] It can be seen that the existing plate-type protection is mainly partial protection, lacking all-round protection, fine particles such as sediment and dust can still enter the interior, and during long-term use, it is easy to cause water ingress and corrosion at the connector end of the box, causing battery insulation Fault; while directly using heat-shrinkable tube wrapping method is difficult to dismantle, inconvenient for maintenance, and can not be reused after dismantling, increasing the cost
