Abstract
The utility model discloses a table connecting terminal for the calibration of a three-phase ammeter, which comprises a shell body, six sliding blocks and six inlaying grafting metal bars. The terminals of the inlaying grafting metal bars are arranged toward lateral side in the middle of each inlaying grafting metal bar, a metal block is fixed on the junction of the middle of the internal surface of the upper edge of the shell body and the middle inlaying grafting metal bars, mutual insulating separated metal blocks are respectively fixed on the junction of the two ends of the external side of the lower end of the shell body and two pairs of inlaying grafting metal bars of two sides, a metal plate is respectively fixed on the bottom of the two pairs of inlaying grafting metal bars. When the springs on the inlaying grafting metal bars are relaxed, the terminals of the middle two inlaying grafting metal bars and the metal plates fixed on the two pairs of inlaying grafting metal bars of two sides are respectively touched with the corresponding metal blocks. So, when the table connecting terminal is adopted to check the three-phase ammeter, the manual short circuit connection isn't needed before checking the three-phase ammeter, the connecting wires of current short circuit aren't needed to disassembly when checking the three-phase ammeter, the calibration of the ammeter is very convenient.
Description
Technical field
The utility model relates to the auxiliary equipment on a kind of watt-hour meter checking table, specifically is used for the meter-connecting wiring terminal of verification three phase watt-hour meter on the watt-hour meter checking table.
Background technology
The meter-connecting wiring terminal that is used at present the verification three phase watt-hour meter on the watt-hour meter checking table generally comprises housing, six slide blocks and six roots of sensation grafting metal bar etc., and peg graft with needing the school watt-hour meter in the upper end of grafting metal bar, its lower end and electric current connection.Because carry out batch calibration during the checking table calibration, connection terminal is connected mutually, so certain connection terminal is during calibration, needs earlier the electric current wiring short circuit of grafting metal bar lower end is connected, and takes apart during calibration again, bothers very much.
Summary of the invention
Technical problem to be solved in the utility model is to provide and need not that the man-made short-circuit connects before a kind of calibration, need not to dismantle the three-phase kilowatt-hour meter verification meter-connecting wiring terminal of short circuit current wiring during calibration, and it makes the verification of three phase watt-hour meter become convenient.
For solving the problems of the technologies described above, three-phase kilowatt-hour meter verification of the present utility model comprises housing with meter-connecting wiring terminal, six slide blocks and six roots of sensation grafting metal bar, elasticity is connected in the respective slide after overlapping upper spring on the every grafting metal bar respectively, the terminals of grafting metal bar are located at the centre of the metal bar of respectively pegging graft towards the lateral, centre at the inside surface of described housing upper edge, its joint with middle two grafting metal bars is fixed with a derby, two ends at described housing lower end lateral surface, its joint with two pairs of grafting metal bars of both sides is fixed with the derby that mutually insulated separates respectively, the bottom of these two pairs of grafting metal bars is fixed with a sheet metal respectively, when the spring on the grafting metal bar was loose, fixing sheet metal touched with the respective metal piece respectively and lumps together on two pairs of grafting metal bars of terminals and both sides of middle two grafting metal bars.
Above-mentioned three-phase kilowatt-hour meter verification meter-connecting wiring terminal is at the two ends of described housing lower end lateral surface, respectively be fixed with a derby along the both sides, front and back of slide block.
Above-mentioned three-phase kilowatt-hour meter verification meter-connecting wiring terminal touches convex respectively being provided with of upside of the fixing sheet metal in the two pairs of metals grafting in inboard and the both sides rod bottom of middle two grafting metal bar terminals
The point.
Above-mentioned three-phase kilowatt-hour meter verification meter-connecting wiring terminal, cover is inserted a case in the lower end of described housing front side, and the lower end of described housing rear side then extends into a shutter downwards.
After adopting technique scheme, because the joint at two pairs of grafting metal bars of the two ends of housing upper edge inside surface and middle two electric current grafting metal bar joints, housing lower end lateral surface and both sides is fixed with derby respectively, when checking table is in non-calibration state, spring on the grafting metal bar is loose, the three pairs of electric current grafting metal bars by terminals or on it fixing sheet metal touch with a respective metal piece respectively and lump together the short circuit conducting.And when checking table was wanted calibration, by after inserting in the grafting metal bar, grafting metal bar, terminals, spring pressed down together with watt-hour meter, grafting metal bar and derby are thrown off, be in non-short circuit conducting state, therefore need not man-made short-circuit's connection or the wiring of dismounting short circuit current again, calibration is very convenient.Each fixes the current capacity that a derby can alleviate derby and sheet metal in the both sides, front and back of slide block.The contact that terminals inboard and sheet metal upper end upwards is convexly equipped with can guarantee good contact the between grafting metal bar and derby.In addition, three derbies are isosceles triangle and are distributed in the housing top and bottom, and the grafting metal bar of both sides can be substantially continuously be drawn close apart from ground and middle grafting metal bar, the needs of different specification size when adapting to calibration.
