Description
Technical field
The utility model relates to a kind of plug, especially at socket quantity anxiety and the multipurpose plug that has under the dangerous operating position.
Background technology
At present, known attaching plug is to be combined by plastics stand, copper sheet and corresponding trip bolt.When the limited auto production line of supply socket, public arena and family and other need be used multiple electrical equipment simultaneously, have to add in addition and use electric socket, bring great inconvenience to use.Though the plug that has also has the function of socket concurrently, but simultaneously compatible straight cutting and oblique cutting dual mode on two kinds of functions of plug and socket, and without function of socket the time, socket has unsafe factor to welding spark, wet environment and child are arranged, and causes electric shock accidents easily.
Summary of the invention
Existing attaching plug can not be used the plurality of specifications electric socket and the plug that can't use, have under limited supply socket quantity has function of socket concurrently in order to overcome, but moist and aspect deficiencies such as having unsafe factor in child's the environment arranged.The utility model provides a kind of safety plug of expanding, and this plug has the plate that can adapt to multiple inserted mode, and the while is extension socket quantity when needed, and further improve its safety in utilization.
The technical scheme that its technical problem that solves the utility model adopts is: change the internal structure of attaching plug and the structure of interior metal part, the circular hole of two circular holes and a band rectangular channel is set below the connector assembly matrix, two circular holes wherein just are being used for holding plug, the negative pole assembly, and just, the negative pole assembly can rotate therein, satisfy it and turn to user demand, the circular hole of band rectangular channel is used for holding the ground wire utmost point (i.e. zero utmost point) assembly, the plug blades bottom of this ground wire utmost point (i.e. zero utmost point) assembly is connected on the alignment pin, plug blades just in time is retracted after 90 ° of alignment pin reversings and is contained in the rectangular channel, reaches like this and can insert any purpose that satisfies the supply socket of basic specification.Simultaneously, the last end face of blind plug pedestal is provided with three jacks in the position corresponding with ground wire utmost point assembly and positive and negative electrode assembly, positive and negative electrode jack shape Ji Zhichakou and oblique cutting mouth are one, can satisfy any standard plug and insert, and can expand as socket to reach when needing.
Further, for fear of moist and the unsafe factor that exposed jack exists in child's the environment is arranged, the utility model has installed safety cover additional in the one side that is provided with jack, does not need to do the socket time spent over cap is covered, with the same safe ready of ordinary plug.
The beneficial effects of the utility model are: both can be used as ordinary plug and used, and be applicable to the plurality of specifications electric socket by the conversion of plug blades angle; Can under the situation that supply socket can not increase, satisfy the needs of a plurality of plug socket powers again, fully taken into account the fail safe of using with fashion, simple in structure, be particularly useful for auto production line, public arena and family and other need use the occasion of multiple electrical equipment simultaneously.
