So the utility model can decrease the socket cost and the socket volume, decrease the product weight and is more convenient to be produced; besides, the appearance of the utility model is beautiful; the installation and utilization is more convenient; the circular leg and the flat leg in the utility model are all made of an elastic copper material so as to make the use of the socket more reliable.
Description
Technical field
The utility model relates to a kind of three-phase four-wire socket.
Background technology
At present, three-phase four-wire socket electrical equipment many and that power is bigger is used.This socket is because the electric current, the voltage that bear are bigger, and size is also bigger.Therefore its form is more single, only suitable round pin plug or only suitable flat pin plug, and the versatility that has caused socket to use like this is relatively poor, and the utilance of material, area is lower.
Summary of the invention
The purpose of this utility model is a kind of box-like three-phase four-wire socket that can be fit to flat pin and circle pin three-phase and four-line plug respectively simple and reasonable for structure of design.
The purpose of this utility model is achieved in that box-like three-phase four-wire socket structure is made up of housing, circle pin jack, flat pin jack and terminals; Circle pin jack and flat pin jack are distributed on the housing, and are respectively equipped with round pin and the flat pin that links to each other with respective terminal in two holes, and the circle pin comprises phase, zero circle pin, and flat pin comprises phase, zero flat pin, and terminals are installed in the housing, and the circle pin is distributed in the top of flat pin.
Two adjacent round mutually pin of box-like three-phase four-wire socket are connected by sheet metal with mutually flat pin, and zero circle pin is connected by sheet metal with zero flat pin, and the sheet metal end is connected with respective terminal.
The round mutually pin of box-like three-phase four-wire socket respectively is three with mutually flat pin, zero circle pin respectively is one with zero flat pin, three line ends that join in the described terminals are arranged at a side of housing, one zero terminals are positioned at the opposite side of housing, three round mutually pin are triangularly arranged on housing near joining line end one side, zero circle pin is positioned at the housing opposite side, three mutually flat pin are triangularly arranged in three round mutually pin near the distolateral adjacent of phase connection, zero flat pin is positioned at zero circle pin inboard, promptly round pin is distributed in the top of flat pin, the circle pin is positioned at the zero terminals direction near housing, and flat pin is positioned at the phase connection extreme direction near housing.
Also be provided with installing hole on the housing of box-like three-phase four-wire socket.
The phase of box-like three-phase four-wire socket, zero circle pin with mutually, zero flat pin all adopts copper product to make, housing adopts flame-retardant reinforced nylon to make.
Be provided with four round pin jacks and four flat pin jacks on socket of the utility model respectively, can be respectively applied for grafting round pin plug and flat pin plug, to adapt to different plug needs, the material of the described box-like three-phase four-wire socket of this product, the utilance of area are higher, versatility is stronger, has reduced the socket cost relatively, has also reduced the socket volume simultaneously relatively, reduced the weight of product, and the processing of being more convenient for; And the utility model good looking appearance, easy to install, round pin in this product and flat pin all adopt copper product to make, and elasticity is better, thus it is more reliable that socket is used.
