Abstract
The utility model discloses a sampling resistor comprising pure copper sheets, a manganese copper alloy plate, sampling wires and heat shrinkable tubes. The number of the pure copper sheets is two; the number of the manganese copper alloy plate is one; the two pure copper sheets and the manganese copper alloy plate are welded into a whole by an electron beam or laser; 1-2 salient point(s) is (are) separately reserved on the pure copper sheets; the sampling wires are welded on the salient points; and the root parts of the sampling wires are sleeved with the heat shrinkable tubes. The sampling resistor overcomes the defect of the traditional sampling resistor that material waste is caused by welding the two pure copper sheets and a manganese copper material in a stacking manner. As a solder and a soldering flux need not to be additionally added during the welding process, both the product and the production process thereof have better environmental-protection property.
Description
Technical field
The utility model relates to a kind of resistor, especially a kind of sample resistance device.
Background technology
Existing sample resistance device all is welded by two pure copper materials and the stack of a slice copper-manganese material, the sample resistance device of this form is owing to its material stack causes waste of material serious, volume is also bigger, and because scolder and scaling powder the time have been added in welding, its feature of environmental protection also is difficult to guarantee.
The utility model content
(1) technical problem that will solve
Technical problem to be solved in the utility model is to provide the sample resistance device at the existing in prior technology defective, solved the prior art waste material, installing space is big and the problem of feature of environmental protection difference.
(2) technical scheme of being taked
The technical scheme that its technical problem that solves the utility model adopts is: sample resistance device, structure comprise fine copper sheet, manganin sheet; Described sample resistance device also comprises sample line and heat-shrink tube; Described fine copper sheet is that 2 and manganin sheet are 1 and become one by electron beam or laser welding; Respectively leave 1-2 salient point on the fine copper sheet, weld sample line above, the root of sample line is with heat-shrink tube.
Described copper-manganese is in the centre, and fine copper is on both sides, and is in same plane.
Described fine copper two ends offer installing hole as required.In order to connect extrinsic current.When current signal was flowed through the sample resistance device, the sample line from salient point carried out sample of signal, realized the effect of big current signal being monitored by small-signal.
(3) sample resistance device of the present utility model compared with prior art has following beneficial effect:
The utility model sample resistance device because pure copper material and copper-manganese material weld not stack side by side, thereby has reduced the material serious waste that traditional sample resistance device causes owing to the material stack.In addition, (no matter being the welding of fine copper and copper-manganese, the still welding of little lead) do not added scolder and helped welding machine, thereby more can guarantee the feature of environmental protection of product in the utility model sample resistance device welding process.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further specified.
Fig. 1 is the structural representation of the utility model sample resistance device;
Fig. 2 cuts into integrally welded schematic diagram behind the billot for the fine copper sheet of the utility model sample resistance device and manganin sheet.
Among the figure: 1, fine copper sheet; 2, manganin sheet; 3, sample line; 4, heat-shrink tube; 5, installing hole.
Embodiment
Shown in figure, the sample resistance device, structure comprises fine copper sheet 1, manganin sheet 2; Described sample resistance device also comprises sample line 3 and heat-shrink tube 4; Described fine copper sheet is that 2 and manganin sheet are 1 and become one by electron beam or laser welding; Respectively leave 1-2 salient point on the fine copper sheet, weld sample line 3 above, the root of sample line is with heat-shrink tube 4.
Described copper-manganese is in the centre, and fine copper is on both sides, and is in same plane.
Described fine copper two ends offer installing hole 5 as required.In order to connect extrinsic current.When current signal was flowed through the sample resistance device, the sample line from salient point carried out sample of signal, realized the effect of big current signal being monitored by small-signal.
Its production technology is earlier pure copper material and copper-manganese material to be divided into billot, place special fixture (the manganin sheet is in the centre, and the fine copper sheet is on both sides, and is placed side by side) then, on electron beam welding machine or laser welder, weld, three block of material are welded into a whole.
The material that butt welding connects is cut into the shape that needs with special fixture in the punch press upper punch.
The sample line of on the reservation salient point of the good sample resistance device of stamping-out, burn-oning, and the heat-shrink tube that cuts is set to root solder joint position, by heating heat-shrink tube is shunk, the butt welding point root plays the effect of protection.
Above-described only is preferred implementation of the present utility model.Should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, all belong to protection range of the present utility model.
Claims (3)
1, sample resistance device, structure comprise fine copper sheet, manganin sheet; It is characterized in that: described sample resistance device also comprises sample line and heat-shrink tube; Described fine copper sheet is that 2 and manganin sheet are 1 and become one by electron beam or laser welding; Respectively leave 1-2 salient point on the fine copper sheet, weld sample line above, the root of sample line is with heat-shrink tube.
2, sample resistance device according to claim 1 is characterized in that: described copper-manganese is in the centre, and fine copper is on both sides, and is in same plane.
