Description

Technical Field

[0001] The utility model relates to the technical field of battery connector processing, in particular to a connector bending tool. Background Art

[0002] The new energy industry is booming, and battery systems have attracted much attention. As the smallest battery unit, the battery cell needs to be modularized when used. In this process, the electrical connectors that connect the single battery cells in series / parallel are crucial, and therefore have also been widely studied. The function of the battery connector is to connect the single battery cells in series (parallel) to ensure that the battery pack forms an electrical connection path so that the battery pack can provide electrical energy. The battery connector needs to be bent during processing.

[0003] The publication number CN 218252292 U discloses a bending tool for a copper bar connector, including a clamping unit, a first bending wrench and a second bending wrench. The first bending wrench is arranged on the clamping unit, and an initial protrusion and a limit protrusion are arranged on the clamping unit or the first bending wrench. The lines between the initial protrusion, the hinge point of the first bending wrench and the limit protrusion form a fixed angle; the second bending wrench has the same structural arrangement as the first bending wrench. The copper bar connector is fixed on the clamping unit, and the first bending wrench is rotated from the initial protrusion to the position of the limit protrusion, and a horizontal plate of the copper bar connector is bent clockwise to a fixed angle. Similarly, the second bending wrench bends the other horizontal plate of the copper bar connector counterclockwise to a fixed angle, so that the two horizontal plates of the copper bar connector are still parallel to each other, and at the same time, the angle of the fixed angle is formed between the horizontal plate and the vertical plate of the copper bar connector, thereby improving the processing efficiency and quality.

[0004] However, the bending tool has the following shortcomings: the tool can bend the connector to a fixed angle when in use, but often due to the deviation in the lengths of both sides of some connectors during the center bending process, the sizes of the connectors after bending are quite different, which affects their subsequent processing.

[0005] To this end, the utility model provides a connector bending tool to solve the above-mentioned problem. Utility Model Content
