Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wiring connectors, and more particularly to a resistance test connector for wire connection. BACKGROUND

[0002] As a basic link in the fields of power transmission, electronic device assembly, industrial control, etc., the stability of the connection resistance of the wire connection directly determines the safety, reliability and energy efficiency of the system operation. In key scenarios such as power grids, new energy vehicles, aerospace, and precision electronic manufacturing, an excessively large connection resistance can easily cause local heating and increased energy loss, and in severe cases, can lead to joint ablation, equipment failure, and even safety accidents. On the other hand, an abnormally small resistance value may indicate potential problems such as loose connection structure and poor contact, affecting signal transmission accuracy or power supply stability. Therefore, accurate and efficient testing of the resistance value of the wire connection point is a core link in product factory detection, equipment maintenance, and engineering quality acceptance, and is also a key technical support for ensuring the long-term stable operation of various electrical systems. The current mainstream method for testing the resistance of wire connection mainly relies on traditional general-purpose test instruments (such as multimeters and milliohm meters) combined with conventional wiring terminals, alligator clips or probes to achieve connection.
