Description
Technical field
The utility model relates to socket field, particularly relates to a kind of three-phase and four-line conversion socket.
Background technology
Three-phase four-wire system, in low-voltage network, transmission line generally adopts three-phase four-wire system, and wherein three-line represents A respectively, B, C three-phase, and another is neutral line N.In the single-phase power transmission line entering user, have two lines, one we be called phase line L, we are called center line N for another, and center line under normal circumstances will by electric current to form the loop of electric current in uniline.And in three-phase system, during three-phase equilibrium, the neutral line is currentless, therefore claim three-phase four-wire system.Factory, building site all use the ammeter of three-phase and four-line, but general machine in normal service is all 220V, so need to change.
Utility model content
To the present situation of above-mentioned prior art, technical problem to be solved in the utility model is to provide a kind of three-phase and four-line conversion socket being suitable for multiple plug.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of three-phase and four-line conversion socket; comprise upper cover and lower cover; cover on described and be provided with socket groove; described socket groove comprises flat 10A socket groove, round end 10A socket groove, 16A socket groove and zero line groove; be provided with escutcheon between described upper cover and described lower cover, described escutcheon is provided with shutter, and this shutter is corresponding with described socket groove; be provided with inserted sheet in described lower cover, this inserted sheet is provided with shell fragment.
Further, described inserted sheet is provided with protection doorframe, for the protection of inserted sheet.
Further, described protection doorframe is provided with embraces pin, and this armful of pin is corresponding with described shutter.
Further, described escutcheon side is provided with wiring board, for providing electric power.
Further, cover on described and be provided with lampshade, for display working condition.
Further, outside described lower cover, be provided with depression, for facilitating plug socket.
Compared with prior art, the utility model has the advantage of: the utility model is by arranging 10A socket groove, round end 10A socket groove, 16A socket groove, but this three kinds of electric currents and plug construction; By arranging shutter, directly contacting an armful pin for the protection of outside by socket groove, improving fail safe; By arranging shell fragment, inserted sheet can be upspring, when using inserted sheet, play a supportive role, the utility model is reasonable in design, can large-scale promotion.
