A mechanical plug-in for new energy vehicles

Abstract

The invention relates to a mechanical insert for a new energy vehicle, comprising an interface part electrically connected to a copper bar of a new energy vehicle battery power assembly, and a joint part electrically connected to a vehicle MCU; the interface part includes a coated copper bar Connecting the cylindrical chamber of the wire row, the middle position of the front end face of the cylindrical chamber is provided with an electrical connection plug, and the electric connection plug is arranged along the forward extension of the cylindrical chamber, and the front end surface of the cylindrical chamber is arranged with a ring of electrical connection plugs. Conductive elastic pressure piece, the anti-conductive elastic pressure piece includes multiple sets of stacked elastic pressure rings successively connected back and forth along the length direction of the electrical connection plug, the ring centers of the multiple sets of elastic pressure rings are located on the same axis line , and the center of the vertical electrical connection plug passes through the axis line, the front ring diameter of each set of elastic pressure rings shrinks forward in sequence along the arrangement direction of the electrical connection plug, when the anti-conductive elastic pressure piece is in a natural state, The frontmost elastic pressure ring extends in front of the electrical connection plug.

Description

technical field [0001] The invention relates to the field of new energy vehicles, in particular to a mechanical insert for new energy vehicles. Background technique [0002] New energy vehicles mainly include pure electric vehicles, extended-range electric vehicles, hybrid vehicles, fuel cell electric vehicles, and hydrogen engine vehicles. The battery power pack is an important part of it. The battery power pack is connected to the vehicle MCU through a mechanical plug-in. The mechanical plug-in of the new energy vehicle battery power assembly is completed through the clamping of the interface part electrically connected to the copper bar of the battery power component of the new energy vehicle and the joint part electrically connected to the MCU of the vehicle. It is easy to cause the breakage of the clamping structure, which will lead to the loosening of the electrical connection between the interface part of the copper bar electrical connection of the new energy vehicle ...
