The positioning components on the feeding base, along with the clamping and positioning components and insulating clamps on both sides of the testing fixture, work together to ensure that the contactor arrives at the testing position stably and accurately during the feeding process.

[0038] 2) Electrical performance testing:

[0039] The lifting slide cylinder of the probe mechanism moves, causing the insulating mounting base and the retractable test probe to rise or fall vertically, so that the test probe contacts the corresponding test point of the contactor to perform electrical performance testing.

[0040] 3) Continuity / breakpoint attraction test:

[0041] The coil test power source (pen-shaped cylinder) of the coil attraction mechanism is started, driving the coil assembly to slide inside the coil attraction bracket, placing the coil on the contactor on the feeding mechanism, and then connecting the circuit to perform a continuity test.

Each testing mechanism can work collaboratively to complete different test items sequentially without frequent equipment changes or test position adjustments, further accelerating the testing process. The probe mechanism, coil engaging mechanism, and clamping mechanism operate quickly and precisely, enabling the completion of electrical performance tests, continuity tests, and pressure tests in a short time, reducing testing time and increasing test output per unit time. The positioning and clamping positioning components of the feeding mechanism ensure accurate and stable contactor positioning during testing, avoiding test errors caused by positional deviations. The retractable probe of the probe mechanism accurately contacts the test point, and the lifting slide cylinder ensures the probe's movement accuracy, thereby improving the accuracy of electrical performance testing. The pen-shaped cylinder of the coil engaging mechanism provides stable driving force, ensuring the coil is accurately fitted onto the contactor, guaranteeing the accuracy of continuity tests. Sensors at the beginning and end positions monitor the cylinder's movement status in real time, further ensuring test reliability. The clamping mechanism's linear clamping module, pressure sensor, and displacement sensor precisely control the clamping force and displacement, ensuring the contactor operates in the appropriate condition during testing and improving the accuracy of pressure testing.

The probe mechanism's retractable detection probe can be adjusted according to different testing requirements, and the coil assembly of the coil engaging mechanism can be replaced according to different contactor models, increasing the tester's flexibility. The insulating mounting base and insulating clamps effectively prevent safety accidents such as leakage during testing, improving testing safety.
