Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment:
In Fig. 4～7: be provided with a little die cavity and three big die cavities that structure is identical in the box body 3, in described each big die cavity, be provided with an electric current input terminal 13 and electric current outlet terminal 5, voltage input terminal 10 and a voltage outlet terminal 7 and a current terminal 9, in described little die cavity, be provided with a voltage input terminal 10 and a voltage outlet terminal 7.Electric current input terminal 13 is positioned at the below of electric current outlet terminal 5, and electric current brace 14 is communicated with by be installed on the electric current input terminal 13 slidably by screw between the two-terminal; Voltage input terminal 10 is positioned at the below of voltage outlet terminal 7, and voltage brace 8 is communicated with by be installed on the voltage input terminal 10 slidably by screw between the two-terminal; Brace 12 is communicated with by be installed on the current terminal 9 slidably by screw between current terminal 9 and the electric current input terminal 13.
For easy to use, the position on the top of box body 3 corresponding to each connection terminal is provided with binding post 6, each binding post 6 respectively with corresponding connection terminal by being threaded; For the ease of wiring, be equipped with wiring hole 15 in the bottom of electric current input terminal 13, voltage input terminal 10 and current terminal 9.For the ease of the connection of standard scale, on each electric current input terminal 13, electric current outlet terminal 5 and voltage input terminal 10, be respectively equipped with a jack screw 11.
Be not difficult to find out that from Fig. 1 traditional mounting means is all cumbersome for verification, replacing electric energy meter 1, must can carry out around the back to measuring screen 2; Mounting means shown in employing Fig. 2,3 is then very simple, only needs binding post 6 of the present utility model is directly inserted in the wiring hole of electric energy meter 1 correspondence, by lead the utility model is connected with the terminal row 4 that is positioned at measuring screen 2 then to get final product; The all working of verification, replacing electric energy meter 1 all can be finished before table, and is very convenient.
Because the principle of work of A, the B of electric energy meter, C three-phase measuring sensor is identical, be example only therefore with the A phase measuring sensor of electric energy meter, principle of work of the present utility model is illustrated:
