Reliability detection device of relay

The invention discloses a reliability detection device of a relay. The relay reliability detection device comprises a control module and a test tool. Wherein the testing tool comprises at least one testing carrier and at least one rotating mechanism, and the rotating mechanisms are connected with the testing carriers in a one-to-one correspondence manner; each test carrier is provided with a detection circuit, the test carriers are used for placing relays, and after the relays are placed, contacts of the relays are connected with the detection circuits; the rotating mechanism is used for driving the test carrier to rotate by different angles; and the control module is electrically connected with a coil of the relay and the detection circuit, and is used for outputting starting voltage to the coil of the relay and determining the reliability of the relay at different angles according to the output state of the detection circuit. According to the invention, the reliability of the relay can be comprehensively de
