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 be respectively equipped with the round pin and the flat pin that link to each other with respective terminal in two holes, the circle pin comprises phase, zero circle pin, and flat pin comprises phase, zero flat pin, terminals are installed in the housing, and circle pin jack is distributed in flat pin jack periphery.
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, and three mutually flat pin are triangularly arranged in three inboard adjacents of round mutually pin, and zero flat pin is positioned at zero circle pin inboard.
Also be provided with installing hole on the housing of box-like three-phase four-wire socket.
Box-like three-phase four-wire socket is characterized in that described back side of shell is provided with the track card base that can move up and down, and the below of track card base is provided with groove.
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.
