Special connection device for mechanical characteristic test of circuit breaker

The invention relates to a special connection device for a mechanical characteristic test of a circuit breaker. The special connection device is characterized by comprising a pinhole socket, a connection wire and a wire clamp, the pinhole socket is an insulator in a columnar structure, the center of one end of the pinhole socket is provided with a conducting jack, the bottom of the jack is connected with the connection wire which is led out from the other end of the pinhole socket, and the other end of the connection wire is connected with the wire clamp. In the mechanical characteristic test of the circuit breaker, the pinhole socket can directly sleeve each pin of an aviation plug to realize connection test, and safety and reliability are achieved while operation efficiency is improved.
