Abstract

The invention relates to a novel male and female plug used for a dust collector. The bottom part of the plug pin of a male plug is provided with a fastening sealing structure. The fastening sealing structure comprises a sealing convex stand, and a fastening sealing ring and a fastening sealing protrusion which are formed by rubber elastomers. The opening of a female plug is provided with a sealing pit which comprises a first sealing pit and a second sealing pit from outside to inside. The cross section of the first sealing pit has an inverted trapezoid structure and the shape and size of the first sealing pit are matched with those of the sealing convex stand which is sleeved by a plug sealing ring. The shape and size of the second sealing pit are matched with those of the sealing protrusion. The plug pin of the male plug is plugged into the opening of the female plug so as to be closely connected with the opening of the female plug. Problems that the plugging part of the male and female plug is liable to loose and line short circuit and even electric leakage situations are liable to occur are solved so that safety hidden trouble is avoided.

Description

technical field [0001] The invention relates to a novel male and female socket, in particular to a novel male and female socket for a vacuum cleaner, which belongs to the field of power connection wires for electrical equipment. Background technique [0002] At present, the straight-shaped power connection wire is commonly used in vacuum cleaners. When the electric floor brush of the vacuum cleaner works for a long time, the straight-shaped power connection wire cannot withstand high-frequency bending, which is easy to cause damage to the wire body and loose connectors. [0003] The current power supply cables are usually inserted through male and female plugs. The structure of the current male and female plugs includes a male plug body and a female plug body. One end of the male plug body is provided with a male housing, the male housing is provided with an insert spring, and the female plug One end of the main body is provided with an open female casing. When the male casi...
