Description

Technical Field

[0001] The utility model relates to the technical field of terminal wire structures, in particular to a terminal wire structure. Background Art

[0002] Battery terminal wires are composed of different numbers of single wires according to different overcurrent requirements. Each wire is arranged side by side, and the head is inserted into the connector to connect to the host. The tail conductor is welded to the battery circuit board, which serves as a bridge between the battery and the host. Wrapping the middle area of ​​the terminal wire with acetate cloth tape can achieve a shaping effect. In order to ensure the stability of the welding between the terminal wire pin solder joint and the circuit board pad, the acetate cloth tape must be at least 7.5mm away from the root of the pin. Since there is a distance at the end of the terminal wire that is not wrapped by the acetate cloth tape, it will be squeezed and deformed when the terminal wire is packaged or transported. At the same time, the acetate cloth tape is pulled, which damages the viscosity of the acetate cloth tape, and the terminal wire body will be scattered and skewed, resulting in the misalignment of the terminal wire pin solder joint and the circuit board pad. There are currently two ways to solve the problem of deformation of terminal wire ends: the first is for welding workers to manually smooth the terminal wire ends during operation. This solution will increase working hours and labor costs and reduce production efficiency; the second is for suppliers to wrap the terminal wire ends with masking tape before shipping to achieve a shaping effect. Before welding workers operate, they need to tear off the masking tape and then put it into the jig for welding with the PCB pad. This solution will increase material costs and time costs.
