[0002] As an important component of circuit connection, the terminal bears connection, transmission of electric signal and other functions. Its quality and reliability directly affect the performance and life of the entire circuit system. In practical application, the terminal is often disturbed by external force, among which the torsional force is one of the important reasons causing the terminal failure. The torsional force can cause the terminal to deform, leading to poor contact or even breakage, and rapidly reducing the safety, reliability and stability of the circuit.

[0003] At present, terminal connection is used in many electric tools, electronic equipment and automotive electronic systems, and the terminals in these systems are often subjected to the combined action of vibration, stretching, torsion and other external forces.

If the terminal structure or material cannot withstand continuous torsion, it will cause equipment failure, safety hazards or even fire accidents.

Therefore, a terminal torsion resistance detection device that is convenient, fast, flexible and efficient is urgently needed, which can simplify the operation process and improve the detection efficiency and flexibility and applicability of the test.
