Technical Field
[0001] The utility model relates to the field of production and manufacturing of new energy vehicle junction boxes, and specifically to a new type of DCDC positive and negative connector testing tooling. Background Art
[0002] During the manufacturing process of new energy vehicle junction boxes, the A pin of the DC / DC positive / negative connector must be connected to the battery's total positive circuit, and the B pin of the DC / DC positive / negative connector must be connected to the battery's total negative circuit. It's common for pins A and B to be connected reversed, with pin A connected to the battery's negative circuit or pin B connected to the battery's positive circuit. Since the interior of the high-voltage box cannot be inspected after assembly, tooling is required to inspect the internal wiring of pins A and B to ensure product quality.
