Multifunctional test power source access device

The utility model discloses a multifunctional test power source access device, comprising an experiment plugboard, a wiring mechanism, and an insulating sleeve. The tail end of the wiring mechanism and the experiment plugboard are connected by a wire. The front end of the wiring mechanism is connected with the insulating sleeve. The middle of the insulating sleeve is provided with an insulating isolation plate, so that wire chucks are respectively placed in two different insulating cavities, so as to realize safe insulation. The insulating isolation plate is provided with a clamping column, so the chucks can be clamped on the clamping column and are prevented from dropping. Since two binding posts of a plug are separated, the plug just needs to be put in one of the insulating cavities, and an insulating cover is closed. The insulating sleeve is designed in a manner capable of opening and closing, so the insulating sleeve can realize closing and locking under the action of the insulating cover, so as to realize an insulating function. The device is worthy of popularizing and applying.
