Abstract
The utility model discloses an electronic type electric energy meter current divider which has two input end buttons. A manganese copper plate or a constantan plate is arranged between two input end buttons, and a sampling connecting head is arranged on the manganese copper plate or the constantan plate; the input end button and the manganese copper plate or the constantan plate is welded into integration by a soldering or an energy storage welding. The utility model has the advantages of material saving, the improvement of efficiency and more reliable connection, and because of mature technology of the soldering and the energy storage welding, under the short-time heavy current action, a contact surface is melted, cooled and solidified between the manganese copper plate or the constantan plate and an end button; so the utility model has the advantages of very reliable contact, very little contact resistance and easy control.
Description
The utility model relates to electric energy meter, relates in particular to the electronic electric energy meter shunt.
Present electronic electric energy meter shunt, normally adopt on the terminal of end box and be screwed the brass web joint, add the soldering mode with riveted joint on the two brass web joints and fixedly connected, this diversion structure complexity, the heating phenomenon when easily producing the table overcurrent with the copper-manganese plate.
The purpose of this utility model provides that a kind of cost is low, efficient is high, the electronic electric energy meter shunt of good reliability.
In order to achieve the above object, the utility model is taked following measures:
The electronic electric energy meter shunt has two input terminals, laterally is provided with copper-manganese or constantan plate between two input terminals, is provided with the sampling joint on copper-manganese or constantan plate, and said input terminal and copper-manganese or constantan plate are integrally welded.
Advantage of the present utility model:
1. economical with materials: save two brass web joints of former scheme and gib screw;
2. raise the efficiency: former scheme need have riveted joint, soldering, screw retention three process, and the utility model obviously saves time only with soldering or store energy welding one procedure;
3. connect more reliable: this is a biggest advantage.Copper-manganese needs to be connected through two roads with terminal in the former scheme, and the fastening degree of screw depends on preceding working procedure, so contact resistance greatly but factor of assurance is little, and the utility model because soldering, store energy welding technical maturity, between copper-manganese and the terminal under the big function of current in short-term, the surface of contact fusing, the cooling after coagulation, therefore contact is very reliable, and contact resistance is very little and easily controlled.
In sum, the phenomenon that the utility model has generated heat in the time of not only can having reduced cost, raise the efficiency but also avoid the table overcurrent has improved reliability.
Elaborate below in conjunction with accompanying drawing:
Accompanying drawing is an electronic electric energy meter diversion structure synoptic diagram.
The electronic electric energy meter shunt has two input terminals 3, between two input terminals, laterally be provided with copper-manganese or constantan plate 2, on copper-manganese or constantan plate, be provided with sampling joint 1, integrally welded between said input terminal and copper-manganese or the constantan plate by soldering or store energy welding.
