Background

Inductors are important components used in the electronics industry, almost all equipment is needed, and because of the large demand. Especially, the temperature characteristic and the reliability of the military inductor in use are critical, and the service life of the whole machine is decisive. The inductor is subjected to temperature impact (-55-125 ℃), temperature circulation (-55-125 ℃) and load test, so that the failed inductor is removed in advance, and the temperature characteristic and the reliability of each inductor are ensured to meet the requirements. At present, the ageing test fixture of for military use inductor is a ordinary plank, adopts plastic line and inductor lead-out wire to twist together when experimental, pastes on the plank through the sticky tape, and connecting speed is slow, inefficiency, and the inductor also rocks, and stability is poor, and the sticky tape phenomenon that drops can appear in long-time loading current, leads to experimental data inaccuracy, can not reach experimental purpose. Meanwhile, different currents are connected by adopting different plastic wires, a large number of plastic wires are needed, and the test cost is increased. When the test is carried out in a high-temperature box, the common wood plate has a fire risk; when tested in a low-temperature box, the test environment temperature is low, moisture, fog or frosting can be generated, and the insulation of a common wood board is poor, and even the common wood board can become a conductor board. Therefore, there is a risk of damage to both the high temperature and low temperature test inductors. Because the inductor body can not be fixed on the plank, the risk that the adjacent inductor lead-out wire of long-time test exists the contact can burn out all inductors in the test like this, directly influence the test progress and the qualification rate of inductor, cause the quality accident, raw and other materials loss influences the delivery progress of inductor, directly influences the complete machine installation of military equipment.
