Specific embodiment
With reference to Figure of description, this utility model is described in detail.
As shown in Figures 1 to 9, a kind of three-phase Split type connecting box that this utility model provides, outer including cuboid
Shell 1 and the multiple joints located inside the shell, shell 1 is provided with the three-phase socket 2 that multiple confession three-phase power lines insert respectively, and three
On the bottom surface of shell 1, shell 1 is provided with the bonnet 7 being detachably connected with it to phase socket 2, and bonnet 7 and shell 1 pass through to insert
Button connects, after cover and be respectively equipped with the external connection end (being not drawn into, can adopt prior art) being connected with external circuit and electric with control
The control connection end (being not drawn into, can adopt prior art) that road connects it is also possible to select other kinds of outer according to practical situation
Connect port, after shell 1 is fastened with bonnet 7, external connection end and control connection end are by inclusion in shell 1.By shell 1 and bonnet 7
Be detachably connected, external circuitses or control circuit are done split type connection with the circuit within ammeter, by different functional areas
Block is distinguish between, and solves the inconvenient installation, maintenance of traditional type binding post and the shortcoming changed, greatly strengthen binding post
Efficiently external and shunting performance.
The copper that ring interface 3 one end fixation that each joint includes being arranged in shell 1 respectively is threaded onto in ring interface 3
Piece 5, the insertion end of copper sheet 5 is slideably positioned in shell 1, and the other end of copper sheet 5 is connected with outside electric elements, three-phase socket
2 position is corresponding with the position of ring interface 3, is provided with the draw-in groove 6 being adapted to ring interface 3 in shell 1, the position of draw-in groove 6 with
External connection end is corresponding with the position controlling connection end, such control circuit, external circuitses and shunt circuit respectively with terminals
Circuit in son connects, and forms overall system.Capacitive element 12 is arranged with each copper sheet 5, capacitive element 12 is arranged at outer respectively
The outside of shell 1 is simultaneously slidably arranged on copper sheet 5, and capacitive element 12 is provided with the electric wire being connected with external circuit, so passes through to adjust
Capacitive element 12 just can be with every attribute of accurate adjustment binding post.Greatly strengthen practicality.
Ring interface 3 can slidably reciprocate in draw-in groove 6, and the direction of insertion of copper sheet 5 is vertical with the glide direction of ring interface 3
Directly, but the copper sheet 5 that again installed of sliding scale limits, so on the side wall of ring interface 3, offer screw, by this
