Description

Technical Field

[0001] The utility model relates to the field of new energy vehicles, and more specifically, to a charging harness connecting device. Background Art

[0002] Faced with increasingly severe energy and environmental problems, the country advocates the development of new energy to reduce carbon emissions and the development of energy-saving and new energy vehicles, especially pure electric vehicles with zero pollution and zero emissions, which are of great significance to energy security and environmental protection.

[0003] When a pure electric vehicle is in use, the electric motor works by electricity, and when the battery is low, it needs to be charged. There are two ways of charging: DC and AC. When using AC for high current charging, multiple chargers are required to work simultaneously. Then the single wiring harness connected to the AC power grid needs to be divided into several branches to connect to the chargers.

[0004] The existing AC charging harness needs to be separated by welding after being led out from the AC power grid, that is, multiple wires to be separated are welded on a main harness. When the wires are separated and connected through the existing charging harness connection device, the wires are introduced into the device from one end as a whole, and the inner end of the wire is connected to the connecting copper bus inside the device after the outer insulation layer is removed. At the same time, the wires are separated, and the wires after separation are connected and used through the outlet at the other end of the device. The problems are:

[0005] After the insulation layer of the wire is removed and the copper busbar is connected inside the device, the sealing and waterproofness of the entire device must be ensured. The existing connection device achieves the waterproof effect by adding a sealing gasket layer to the upper and lower shells. The sealing gasket layer is easily squeezed by the upper and lower shells over time and the waterproof performance is reduced, and the waterproofness needs to be improved. After the wire is connected to the copper busbar and led outward, it is also necessary to seal this part of the wire and the device to prevent water from entering the device through the wire port. The existing connection device cannot meet this requirement well. The connecting copper busbar inside the device is not stable after being connected to the wire, and the wire has become loose inside the device along with the device.

[0006] Therefore, the utility model provides a charging harness connecting device. Utility Model Content
