Abstract
The utility model relates to an electric energy meter, which comprises a sampling resistor and a connecting wire. A wiring terminal is arranged on the sampling resistor. The electric energy meter further comprises an end sleeve welding sheet. One end of the end sleeve welding sheet is fastened onto the connecting wire, and the other end of the end sleeve welding sheet is sleeved on the wiring terminal and welded with the wiring terminal. By means of the electric energy meter adopting the structure, connection of the connecting wire and the sampling resistor is firm, the connecting wire and the sampling resistor can bear large tensile force without loosening, tin is not required to be applied on welding points, all welding can be conducted by using machines, and welding efficiency is high.
Description
Technical field:
The utility model relates to electric energy meter and manufactures the field, specifically is a kind of electric energy meter.
Background technology:
Electric energy meter generally is to adopt sample resistance to be used as the element of current sampling, and in the prior art, the sample resistance in the electric energy meter and the connected mode of connecting line generally are as shown in Figure 1: sample resistance 1a is provided with link 2a; Link 2a adopts sample resistance 1a to go up extended copper sheet, and a sample resistance 1a is provided with three link 2a, and each link 2a all adopts connecting line 3a to connect; Connecting line 3a adopts spot-welded on link 2a, and block tin 5a strengthens on weld then, puts terminal cover 4a protection solder joint at weld then; Adopt this syndeton, connecting line 3a carries out spot-welded on link 2a can adopt the machine welding, needs the artificial tin of going up but go up tin; Operate cumbersomely, waste time and energy, welding efficiency is lower; And this connected mode, solder joint is insecure, bear a little bigger slightly pulling force (as＞8N) time; Just break off easily, reliability is lower.
The utility model content:
The technical matters that the utility model will solve is, overcomes existing technological deficiency, provides the welding efficiency of a kind of sample resistance and connecting line high, the electric energy meter that reliability is high.
The technical solution of the utility model is, a kind of electric energy meter is provided, and it comprises sample resistance, connecting line; Said sample resistance is provided with terminals; It also comprises end cover weld tabs, and said end cover weld tabs one end snaps onto on the connecting line, and the other end is enclosed within on the terminals and with terminals and welds.
After adopting said structure, the utlity model has following advantage:
In the utility model electric energy meter, sample resistance connects with adopting end cover weld tabs being connected of connecting line, and an end of end cover weld tabs snaps onto on the connecting line; The other end of end cover weld tabs is welded on the terminals, adopts this connected mode, and connecting line is more firm with being connected of sample resistance; Can bear bigger pulling force (>=25N) and do not unclamp; And not be used in last tin on the solder joint, and can all adopt the machine welding, welding efficiency is higher.
As improvement, the periphery of said end cover weld tabs also is with a terminal cover, is provided with the tie point that the terminal cover can be protected connecting line and sample resistance, and can plays insulating effect, improves the electrical safety grade.
Description of drawings:
Accompanying drawing 1 is the synoptic diagram of connected mode of the sample resistance of prior art electric energy meter;
Accompanying drawing 2 is synoptic diagram of connected mode of the sample resistance of the utility model electric energy meter;
As shown in the figure: 1a, sample resistance in the prior art, 2a, terminals, 3a, connecting line, 4a, terminal cover, 5a, block tin;
In the utility model: 1, sample resistance, 2, terminals, 3, connecting line, 4, the terminal cover, 5, end cover weld tabs.
Embodiment:
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation.
As Fig. 2, shown in: a kind of electric energy meter is provided; It comprises sample resistance 1, connecting line 3, and said sample resistance 1 is provided with terminals 2, and it also comprises end cover weld tabs 5; Said end cover weld tabs 5 one ends snap onto on the connecting line 3; End cover weld tabs 5 snaps onto 3 last times of connecting line, and end cover weld tabs 5 contacts with the current-carrying part of connecting line 3, and the other end is enclosed within on the terminals 2 and with terminals 2 and welds.
As improvement, the periphery of said end cover weld tabs 5 also is with terminal cover 4, is provided with the tie point that the terminal cover can be protected connecting line and sample resistance, and can plays insulating effect, improves the electrical safety grade.
In the utility model electric energy meter, sample resistance connects with adopting end cover weld tabs being connected of connecting line, and an end of end cover weld tabs snaps onto on the connecting line; The other end of end cover weld tabs is welded on the terminals, adopts this connected mode, and connecting line is more firm with being connected of sample resistance; Can bear bigger pulling force (>=25N) and do not unclamp; And not be used in last tin on the solder joint, and can all adopt the machine welding, welding efficiency is higher.
Certainly; Above-mentioned explanation is not to be the limit value to the essential scope of the utility model; The utility model also is not limited in above-mentioned giving an example; The variation that those skilled in the art person has done in the essential scope of the utility model, remodeling, interpolation or replacement also should belong to the protection domain of the utility model.
