Primary side large current test tool of Hall current sensor

The invention provides a primary side large current test tool of a Hall current sensor, wherein the primary side large current test tool comprises a base and an upper cover; the upper surface of the base is provided with a placement position for the Hall current sensor; the upper cover is arranged above the base during testing, the upper cover is provided with an upper profiling current bar and an upper testing needle which penetrate through the upper cover, the upper profiling current bar and the upper testing needle are both conductors, the bottom of the upper profiling current bar corresponds to a primary side pin of the Hall current sensor so as to input large current to the primary side pin, and the bottom of the upper testing needle abuts against the upper surface of a signal pin of the Hall current sensor. According to the primary side large current test tool of the Hall current sensor, long-time and large-current work of a product can be guaranteed, so that the test precision of the product is improve
