Technical field
The utility model relates to a kind of improvement of electric energy meter combined connection box voltage brace, specifically a kind of electric energy meter combined connection box chopper switching regulator voltage brace that can disposablely push disconnecting or connection to four voltage braces aside.
Background technology
Voltage brace is the break-make brace of the voltage wiring of the current electric energy meter combined connection box using, and establishes altogether four groups in electric energy meter combined connection box, and every group includes a slide and two screws; Described voltage brace is rectangular pieces, and middle part is provided with the bar shaped slide opening of charged terminal screw, and upper end is provided with and movable " U " shape bayonet socket docking of the terminal screw of inputting ammeter, and the lower end of voltage brace is provided with the sliding piece perpendicular to vertical voltage brace.This voltage brace deficiency is in use: because voltage brace is installed for vertical, its sliding piece is in lower end, its " U " shape bayonet socket is in upper end, when changing electric energy meter, need with screwdriver, first become flexible the terminal screw of charged terminal screw and input ammeter, then with screwdriver, stir the sliding piece on vertical voltage brace downwards, " U " shape bayonet socket departs from the terminal screw of input ammeter, can make to disconnect ammeter power supply, now voltage brace hangs on charged terminal screw; When having changed electric energy meter and switched on power, with screwdriver, choose again the upwards promotion of sliding piece of voltage brace lower end, " U " shape bayonet socket of voltage brace upper end is stuck on the terminal screw of input ammeter again, thereby switches on power, finally tighten terminal screw and the charged terminal screw of input ammeter.In making operation process, because voltage brace is to be suspended on charged terminal screw, easily rotate and swing, and with " U " shape bayonet socket snap in input ammeter terminal screw position not in one plane, so be difficult to docking, waste time and energy, reduced efficiency, but also very easily produce electric spark, cause dangerous accident.
Summary of the invention
It is a kind of not only simple in structure that the purpose of this utility model is to provide, and need not become flexible terminal screw, can once be switched on or switched off voltage brace, can increase substantially the electric energy meter combined connection box chopper switching regulator voltage brace of efficiency, handling safety.
In order to reach above object, the technical scheme that the utility model adopts is: this electric energy meter combined connection box chopper switching regulator voltage brace, comprise live end voltage terminal screw and output end voltage terminal screw, it is characterized in that: on described live end voltage terminal screw and output end voltage terminal screw, be equipped with the double-deck conducting strip of " L " shape, at the middle part of the riser of the double-deck conducting strip of " L " of live end voltage terminal screw shape, by bearing pin, is flexibly connected and conducts electricity chopper, conduction chopper rotates end and snaps in the riser jaws of " L " the double-deck conducting strip on output end voltage terminal screw, the double-deck conducting strip of " L " shape of described live end voltage terminal screw and output end voltage terminal screw and connection thereof is established four groups altogether, and corresponding thereto, conduction chopper is also established four, and the pommel portion of four conduction choppers is fixedly connected with same connecting rod.
The utility model is also implemented by following measure: the middle part of described connecting rod is provided with poke rod.
The beneficial effects of the utility model are: this electric energy meter combined connection box chopper switching regulator voltage brace, owing to having adopted chopper switching regulator to be once switched on or switched off voltage brace, so need not become flexible charged terminal voltage terminal screw and output end voltage terminal screw, and can operate outward in terminal box, simple in structure, handling safety, can increase substantially efficiency.Can be widely used in electric energy meter combined connection box.

Fig. 2 is that structure of the present utility model is analysed and observe enlarged diagram along A-A.
Fig. 3 is application state schematic top plan view of the present utility model.
In figure: 1, live end voltage terminal screw; 2, output end voltage terminal screw; 3, the double-deck conducting strip of " L " shape; 4, bearing pin; 5, conduction chopper; 6, connecting rod; 7, riser jaws; 8, poke rod; 9, electric energy meter combined connection box; 10, live end voltage wiring terminal; 11, the output end voltage binding post of access ammeter.
Embodiment
With reference to Fig. 1, Fig. 2, make the utility model.This electric energy meter combined connection box chopper switching regulator voltage brace, comprise live end voltage terminal screw 1 and output end voltage terminal screw 2, it is characterized in that: on described live end voltage terminal screw 1 and output end voltage terminal screw 2, be equipped with the double-deck conducting strip 3 of " L " shape, middle part at the riser of the double-deck conducting strip 3 of " L " of live end voltage terminal screw 1 shape is flexibly connected conduction choppers 5 by bearing pin 4, and conduction chopper 5 rotates end and snaps in the riser jaws 7 of " L " the double-deck conducting strip 3 on output end voltage terminal screw 2; Described live end voltage terminal screw 1 and output end voltage terminal screw 2 and the double-deck conducting strip 3 of " L " shape being connected thereof are established four groups altogether, corresponding thereto, conduction chopper 5 is also established four, the pommel portion of four conduction choppers 5 is fixedly connected with same connecting rod 6, by lifting of connecting rod 6, can realize four conduction choppers 5 and lift simultaneously, deviate from the riser jaws 7 of " L " the double-deck conducting strip 3 on output end voltage terminal screw 2, realize deenergization; Equally, by depressing of connecting rod 6, can realize in the riser jaws 7 that four conduction choppers 5 snap in " L " the double-deck conducting strip 3 on output end voltage terminal screw 2 simultaneously, realization switches on power.
As improvement of the present utility model: the middle part of described connecting rod 6 is provided with poke rod 8, realizes lifting of connecting rod 6 by poke rod 8.
While using this practical, Fig. 3 has provided application state schematic top plan view of the present utility model, by live end voltage terminal screw 1 and output end voltage terminal screw 2, the double-deck conducting strips 3 of two " L " shapes are fixed on four live end voltage wiring terminals 10 of electric energy meter combined connection box 9 and on the output end voltage binding post 11 of access ammeter, the pommel of poke rod 8 stretches out from the lower wall middle part of electric energy meter combined connection box 9, cover the transparency cover of electric energy meter combined connection box 9, install, now, in the situation that not opening transparency cover, pressure due to transparency cover, poke rod 8 can not rotate, so connecting rod 6 can not lift, four conduction choppers 5 also just can not be deviate from the riser jaws 7 of " L " the double-deck conducting strip 3 on output end voltage terminal screw 2, can deenergization.When needs are changed ammeter, open transparency cover, by rotating poke rod 8, can make connecting rod 6 lift, four conduction choppers 5 are deviate from the riser jaws 7 of " L " the double-deck conducting strip 3 on output end voltage terminal screw 2, and deenergization, so just can safety operation.
