Abstract

The invention relates to the technical field of new energy cars. A sealing connection structure of a power wire of an electric car comprises a power wire consisting of a first section and a second section; a plug is arranged at the first section, comprising a plug housing; a connecting hole is formed in the plug housing; a conductive inserting pin which is electrically connected with the first section is arranged in the connecting hole; a socket is arranged at the second section, comprising a socket housing, and a conductive socket sleeve which is positioned in the socket housing and electrically connected with the second section; the socket housing is provided with a connector; a through hole which is aligned with the conductive socket sleeve is formed in the connector; the connector is detachably inserted into the connecting hole; the connector and the connecting hole are hermetically connected through an inflating type sealing ring; the conductive inserting pin passes through the through hole to be inserted into the conductive socket sleeve by a pluggable manner. The sealing connection structure has the advantage that the power wire can be detachably connected by a sealing manner; the problem that it is inconvenient to separate a driving motor from a power supply can be solved.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a sealed connection structure for electric vehicle power lines. Background technique [0002] The driving motor and the power supply in the existing electric vehicle are connected together through the power line to realize the power supply of the power supply to the driving motor. Power sources include batteries, wind generators, solar photovoltaic panels, etc. In the patent document with the Chinese patent number 2013100672447, the application publication date being August 27, 2014, and the patent document titled "Pure Electric Vehicle Assisted by Combination of Wind Power and Oil and Electricity", a technology for connecting the drive motor and power supply through a power cord is disclosed plan. The existing connection method is to connect one end of the power cord with the terminal of the drive motor, and the other end with the terminal of the power supply. The ...
