Connecting piece for power battery and signal acquisition wire harness

Abstract

The invention provides a connecting piece for a power battery and a signal acquisition wire harness. The connecting piece is reasonable in structure, the welding quality of the connecting piece and a flexible circuit board can be effectively improved, after the signal acquisition wire harness adopts the connecting piece, the bubble rate of an insulation protection layer can be effectively reduced, the attaching effect and the insulation effect of the insulation protection layer are ensured, a welding portion is arranged at one end of the connecting piece, a welding coating is arranged on the surface of one side of the welding portion, and an NTC avoiding portion is arranged on the welding portion. The connecting piece is characterized in that a notch portion is arranged on the NTC avoiding portion and enables the NTC avoiding portion to be communicated with the outer side of the connecting piece, and an NTC protection boss is arranged on the edge of the NTC avoiding portion.

Description

technical field [0001] The design of the present invention relates to the technical field of power batteries, in particular to a connection piece and a signal collection wire harness for power batteries. Background technique [0002] With the gradual scarcity of global fuel resources and the intensification of environmental pollution, people's awareness of environmental protection has increased, and the voice of protecting the environment and saving resources has become increasingly louder. All countries in the world are developing new energy vehicles to replace traditional internal combustion engine vehicles. Electric vehicles are non-polluting, can be configured in a variety of energy sources, have low noise, and have higher energy conversion efficiency than internal combustion engine vehicles. At the same time, they also have the advantages of simple structure, low operating costs, and relatively good safety. They represent the new generation of environmentally coordinate...

Problems solved by technology

[0005] However, in actual use, it is found that when the design of the above structure is used to weld the NTC connecting piece and the flexible circuit board, due to the existence of the window area, it is difficult to eliminate the bubbles generated by the gasification of the flux during the welding process, which affects the connecting piece and the flexibility. The welding quality of the circuit board; in addition, after the connection of the NTC connecting piece and the flexible circuit board, when the insulating protective layer is applied, air bubbles are likely to be generated, which affects the insulation effect of the insulating protective layer
