Electric energy model differs, cause electric energy meter voltage crimping space, screw place narrower compared with voltage nip width and voltage cannot be got, can only strip off pressure-wire insulating barrier or from situations such as terminal board power takings, in this process, possible damage voltage wire or by mistake touch terminal board current loop.
Chinese patent, the patent No. 201510608706.0, disclose a kind of wiring and quickly connect equipment, particularly to a kind of intelligent electric energy meter voltage link Quick Connect Kit and method, its technical scheme is: include connecting seat, union joint, described connection seat is provided with multiple jack, it is respectively equipped with union joint in described jack, described union joint includes spring bonnet, spring, voltage terminal joint, the front end of spring bonnet is provided with convex gear, spring bonnet is buckled in the inside of jack by convex block card, the inside of described spring bonnet is hollow groove, it is provided with spring inside the hollow groove of described spring bonnet, the bottom of spring connects voltage terminal joint.There is the problem that spring cannot be changed and regulate, and union joint also connects with alligator clamp, it is the most firm to press from both sides, and easily falls.
Summary of the invention
Unstable in order to solve the voltage clip that prior art exists, the problem such as easily loosen, drop, this utility model provides a kind of electric energy meter auxiliary school checking device, and wiring is stable, easy to use.
This utility model solves the technical scheme that its technical problem used: this device includes connecting seat, bindiny mechanism, fixed mechanism, and described connection seat arranges four holes, and position is corresponding with the position of multifunctional meter voltage terminal Stroma respectively；Described bindiny mechanism has four, is arranged in the hole connecting seat, and vertically can move relative to connecting seat；Fixed mechanism has two, the two ends being respectively provided with being connected seat.
As preferably, described bindiny mechanism includes terminal union joint, connecting rod, contact spring, adjusting nut；Described union joint is connected with the upper end of connecting rod, and connecting rod is placed in the hole connected on seat, and connecting rod bottom has screw thread, adjusting nut to be connected with connecting rod, and described contact spring is sleeved in connecting rod, and is connecting between seat and adjusting nut.
As preferably, between contact spring and adjusting nut, it is additionally provided with pad.
As preferably, described union joint is interior for metal hollow cylinder, is outward isolation material.
As preferably, described connecting rod lower end is " one " font.
As preferably, described fixed mechanism is fixed screw, and the top of fixed screw is with stubborn head.
The beneficial effects of the utility model are as follows:
1, external spring can change contact spring easily；
2, the pressure of nut adjustable springs, allows connecting rod contact with the line ball screw of multifunctional meter voltage terminal Stroma tighter,；
3, the lug of measuring instrument is that plug-in type is connected with the connected mode of union joint, and it is more firm to contact, and is difficult to loosen, drop.
