Abstract
The utility model discloses a kind of connecting terminal for electric energy meter row, comprise terminal base, copper bar, relay and mutual inductor, in the corresponding via hole of front end insertion end stroma front bottom end of described copper bar, described relay and mutual inductor are arranged on the rear end of copper bar by screw assemblies, on terminal base below described copper bar front end, be provided with an Elastic buckle to front upper place perk, below the copper bar front end corresponding with this Elastic buckle, be provided with a draw-in groove, the front end of described copper bar is controlled in its via hole that is fixedly mounted on terminal base by Elastic buckle and draw-in groove clamping.The utility model, by setting up respectively the Elastic buckle being used in conjunction with and a draw-in groove at terminal base and copper bar corresponding position, utilizes the Elastic buckle of terminal base to withstand copper bar, prevents that copper bar from inside contracting; Meanwhile, the copper bar no longer inside contracting does not need, for guaranteeing that its displacement error that may exist increases side-play amount, its entire length to be greatly reduced yet again, and shortens approximately 22%, and the cost of copper bar can reduce by 22%.
Description
Technical field
The utility model relates to a kind of connecting terminal for electric energy meter row.
Background technology
Increasingly mature along with national intelligent grid in recent years, to the demand of intelligent electric energy meter, be also very huge, wherein the terminal base of electric energy meter is owing to being share ware (can switch) between the table of different model, so the quality of terminal base, cost (starting material with price also more expensive) are just particularly important, also become a bottleneck of each electric energy meter producer development of restriction.At present, the connecting terminal block of electric instrument is comprised of copper tip and terminal base (insulated plastic glue material) conventionally, and the hole interference fit by copper tip and terminal base forms.And between terminal base and base table, also having requirement dustproof, waterproof, this just makes the design of terminal base more harsh.
Utility model content
The purpose of this utility model is to provide a kind of cost low, easy to assembly, copper tip can firmly be fixed on terminal base connecting terminal for electric energy meter row.
This connecting terminal for electric energy meter row that the utility model provides, comprise terminal base, copper bar, relay and mutual inductor, in the corresponding via hole of front end insertion end stroma front bottom end of described copper bar, described relay and mutual inductor are arranged on the rear end of copper bar by screw assemblies, on terminal base below described copper bar front end, be provided with an Elastic buckle to front upper place perk, below the copper bar front end corresponding with this Elastic buckle, be provided with a draw-in groove, the front end of described copper bar is controlled in its via hole that is fixedly mounted on terminal base by Elastic buckle and draw-in groove clamping.
The utility model is by setting up respectively the Elastic buckle being used in conjunction with and a draw-in groove at terminal base and copper bar corresponding position, when copper bar hot pressing is entered to terminal base, utilize the draw-in groove on the Elastic buckle of terminal base and the correspondence position of copper bar, when being pressed into copper bar, Elastic buckle allows open position by distortion, waits and packs into after copper bar, Elastic buckle restores, the interference fit of the mating surface by copper bar and terminal base surrounding, Elastic buckle withstands copper bar firmly, prevents that copper bar from inside contracting; Meanwhile, the copper bar no longer inside contracting does not need, for guaranteeing that its displacement error that may exist increases side-play amount, its entire length to be greatly reduced yet again, and shortens approximately 22%, and the cost of copper bar can reduce by 22%.The utility model is simple in structure, and layout is tightly short, and assembling process is simple, convenient, firm, and cost is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As can be seen from Figure 1, this connecting terminal for electric energy meter row of the utility model, comprise terminal base 1, copper bar 2, relay 3, mutual inductor 4 with zero line brace, sealing cord 5 and screw assemblies 6, in the corresponding via hole 11 of front end insertion end stroma 1 front bottom end of copper bar 2, on terminal base 1 below copper bar 2 front ends, be provided with an Elastic buckle 12 to front upper place perk, below the copper bar corresponding with this Elastic buckle 12 2 front ends, be provided with a draw-in groove 21, the front end of copper bar 2 is controlled in its via hole that is fixedly mounted on terminal base 1 11 by Elastic buckle 12 and draw-in groove 21 clampings, relay 3 and mutual inductor 4 are arranged on the rear end of copper bar 2 by screw assemblies 6.
Assembling process of the present utility model is as follows:
1, by the plastic body of injection mo(u)lding terminal base 1.
2, while hot the front end hot pressing of copper bar 2 is entered in the corresponding via hole 11 of terminal base 1 front bottom end.
When 3, being pressed into copper bar 2, the front end of copper bar 2 promotes Elastic buckle 12 and is bent downwardly distortion and allows open position.
4, after copper bar 2 packs into, draw-in groove 21 moves to Elastic buckle 12 tops, and Elastic buckle 12 restores, insert in the draw-in groove 21 of copper bar 2 bottoms, top, the interference fit of the mating surface of copper bar 2 and terminal base 1 surrounding, Elastic buckle 12 withstands copper bar 2 firmly, prevents that copper bar 2 from inside contracting.
5, relay 3, mutual inductor 4 use screw assemblies 6 are fixed on to the posterior end face of copper bar 2.
6, load onto sealing cord 5, the utility model is assembled on the body of electric energy meter.
