A multimedia intelligent cleaning system and a control method thereof may include a self-propelled cleaning robot for cleaning a working surface and a safety guard device for connection with the self-propelled cleaning robot. The self-propelled cleaning robot and the safety guard device are detachably connected with each other through a securing assembly. The securing assembly has a first state in which the safety guard device is connected with the self-propelled cleaning robot and a second state in which the safety guard device is separated from the self-propelled cleaning robot. The multimedia intelligent cleaning system further comprises a detection assembly for detecting whether the securing assembly is in the first state or the second state, and a control unit for controlling whether the self-propelled cleaning robot enters a safe activation state depending on a detection signal from the detection assembly.

An electrical connector assembly includes a plug, having a body and multiple pins positioned on the body, and a socket connector including an insulating body. Each pin has an insertion portion extending downward out of the body. The insertion portion has a guide surface, and two contact regions located above the guide surface. The guide surface passes through a vertical center line of the insertion portion. Multiple accommodating holes run through the insulating body vertically. Multiple terminals are respectively accommodated in the accommodating holes. Each terminal is provided with two clamping portions. The guide surfaces guide the pins to be inserted downward into the accommodating holes. When each pin is inserted downward to a final position, the insertion portion is located between the two clamping portions, the two clamping portions are correspondingly in contact with the two contact regions, and the guide surface is located below the two clamping portions.

An apparatus for electrically connecting two downhole components configured to be disposed in a borehole. The apparatus includes two complementing tool connectors which each have a corresponding electrical connector. The tool connectors may mate using a bayonet and slot connection. The slot may be L-shaped or l-shaped. The slot may be configured for straight or rotational engagement of the tool connectors. The electrical connectors may mate using concentric contacts that share the same axis. The electrical connectors are configured to rotate without stressing the contacts during assembly, disassembly, and drilling operations. The electrical connectors may support two or more contacts.
