Battery anti-loosening wiring device used for new energy automobile

Abstract

The invention discloses a battery anti-loosening wiring device used for a new energy automobile. The device comprises a first connector, a second connector and a lead. The first connector is connectedwith a battery module through the lead, and the first connector and the second connector are electrically connected in an inserted mode or a plug-in mode. The first connector comprises a first plastic block, first interfaces and an induction column. The second connector comprises a second plastic block, second interfaces and an armature. The induction column is glued in the first plastic block, one end of the induction column is exposed out of the first plastic block, the first interfaces are arranged in a side surface of the first plastic block and are located on the same side as an end portion, exposed out of the first plastic block, of the induction column, the two first interfaces are connected with an anode and a cathode of the battery module through leads, and the leads spirally wind the induction column in the first plastic block. One side of the second plastic block is provided with a jack and the two second interfaces, the second interfaces are in butt joint with the first interfaces, the armature is embedded in the jack, the jack is in butt joint with the induction column, the lead is glued in the second plastic block, and the second interfaces are connected with the leads.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to a battery anti-loosening wiring device for new energy vehicles. Background technique [0002] New energy vehicles use power batteries as their power source, and power batteries are often installed inside the car in the form of modules, mostly on the chassis of the car. [0003] All electrical equipment inside the car obtains power from the battery module. The battery module is generally a plurality of single batteries connected to each other to form a module, and then powered externally as a whole. The battery module needs to use connectors for electrical wiring when it supplies power to the outside. The quality of the wiring directly determines whether the battery can stably supply power to the outside. [0004] If there is looseness at the battery terminals or the external wiring, it will cause electric sparks and may be a fire hazard. During the driving process of the car, the batt...

[0004] If the battery terminals or the external wiring are loose, it will cause electric sparks, which may cause a fire hazard

During the driving process of the car, the battery connection is often in a bumpy state, and the connection is likely to be loose, and the higher the speed, the more likely to generate high-frequency vibration. The conventional bolt and screw connection structure is likely to move along the contact surface under high-frequency vibration Slip in the loose direction, resulting in poor contact, and for the most important connection between the battery module and the outside world, it is often necessary to use quick-plug and quick-release wiring to facilitate the quick disconnection of the electrical connection when repairing or replacing the battery module, otherwise It is very troublesome to remove a lot of bolts to take out the battery module. The quick plug and quick release is generally in the form of a plug and socket. This wiring method does not have any fastening and is prone to loosening.
