Abstract
The utility model discloses an ammeter-connecting and binding terminal for checking three-phase ammeters, comprising a casing, six blocks and six socket metallic rods, wherein each metallic rod is elastically connected into a corresponding block after being sheathed with a spring respectively, the binding terminal is laterally provided in the middle of the metallic rods outwards, and the inner surface of the upper limb of the casing, the joints of the casing and every two socket metallic rods are embedded with a metallic unit respectively, and each metallic unit is mutually insulated and detached. When using the utility model to check an electric meter, manual short-circuiting connections and disassembling current wirings are not required, thereby checking an ammeter is very convenient, simultaneously the utility model has the advantages of small bulk and low producing costs.
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.When needing to gather stain before the calibration, need elder generation that the electric current wiring short circuit of its lower end is connected, unload again during calibration, very trouble.A kind of improved meter-connecting wiring terminal is also arranged, be provided with a derby at the joint of housing downside outer end and electric current grafting metal bar, so just need not that the man-made short-circuit connects or the wiring of dismounting electric current again, calibration is very convenient.But because it also need increase by a housing again it is encased outside derby, therefore make the volume of whole meter-connecting wiring terminal seem very huge, using some is in the way, and has correspondingly increased its production cost.
Summary of the invention
Technical problem to be solved in the utility model need not when being to provide a kind of calibration that the man-made short-circuit connects or the wiring of dismounting electric current, volume is little, cost is light three-phase kilowatt-hour meter verification meter-connecting wiring terminal, and it can make 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, six slide blocks and six roots of sensation grafting metal bar with meter-connecting wiring terminal, elasticity was connected in the respective slide after every grafting metal bar overlapped upper spring respectively, terminals are located at the centre of grafting metal bar towards the lateral, on the inside surface of the upper edge of described housing, the joint of itself and per two described grafting metal bars is embedded with a derby, mutually insulated separately between described each derby, when the spring on the grafting metal bar was loose, described terminals and described derby touched and lump together.
Above-mentioned three-phase kilowatt-hour meter verification meter-connecting wiring terminal is in inboard, its convex contact that is provided with, position that engages with described derby of described terminals.
After adopting technique scheme, owing to be embedded a derby at housing upper edge inside surface and the increase of electric current grafting metal bar joint, when checking table is in non-calibration state, spring on the grafting metal bar is loose, and three pairs of current terminals 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 metal bar, grafting metal bar, terminals, spring pressed down together with watt-hour meter, the wiring rod is thrown off with derby, be in non-short circuit conducting state, therefore need not man-made short-circuit's connection or the wiring of dismounting electric current again, calibration is very convenient.Before the only a few verification, need not under the situation of short circuit connection, only need derby to be clamped out housing and get final product with pliers, very convenient.Simultaneously, the volume of whole meter-connecting wiring terminal does not increase yet, and uses still as originally just like that smoothly, and compared with existing improvement structure, has more reduced production cost.In addition, the contact that upwards is convexly equipped with, terminals inboard can guarantee good contact the between terminals and derby.

Fig. 3 is a perspective view of the present utility model.
Embodiment
As shown in the figure, the three-phase kilowatt-hour meter verification comprises housing 1, six slide blocks 2 and six grafting metal bars 3 with meter-connecting wiring terminal, slide in the groove that each slide block 2 is offered on housing 1 and by screw 10 location, behind each metal bar 3 cover upper spring 4 of pegging graft respectively elasticity be connected in each slide block 2, terminals 5 are located at the centre of grafting metal bar 3 towards the lateral, the inboard convex contact 7 that is provided with of terminals 5, the electric current external connection is fixed on the terminals 5 with screw 9.On the inside surface of housing 1 upper edge, the joint of itself and per two grafting metal bars 3 is embedded with a derby 6, the silver-plated copper billet of derby 6 usefulness is made, 6 mutually insulateds of each derby separately.When the spring on the grafting metal bar 34 was loose, the contact 7 on the terminals 5 was touched with derby 6 and is lumped together.Whole watt-hour meter meter-connecting wiring terminal is fixed on the watt-hour meter checking table by mounting hole 8.
Claims (2)
1, three-phase kilowatt-hour meter verification meter-connecting wiring terminal, comprise housing, six slide blocks, six roots of sensation grafting metal bar and three derbies, elasticity was connected in the corresponding described slide block after described every grafting metal bar overlapped upper spring respectively, terminals are located at the centre of described grafting metal bar towards the lateral, mutually insulated separately between described each derby, it is characterized in that described three derbies are embedded respectively at the joint on the inside surface of described housing upper edge, between described housing and per two described grafting metal bars.
2, three-phase kilowatt-hour meter verification meter-connecting wiring terminal as claimed in claim 1 is characterized in that, in inboard, its convex contact that is provided with, position that engages with described derby of described terminals.
