Abstract
The utility model discloses a kind of shaped grooved manganese copper diverter, including copper-manganese piece, and copper-manganese piece two sides distinguish the fixed T2 copper sheet of electron beam welding, form alloy weld seam between copper-manganese piece and T2 copper sheet；The copper-manganese piece is longitudinally spaced to be equipped with one group of lateral rectangular straight slot；The fixed T2 copper sheet of electron beam welding is set, forms alloy weld seam between copper-manganese piece and T2 copper sheet, red copper and copper-manganese come into full contact with, and reduce contact resistance, while reducing material and energy consumption；In addition, can effectively promote product power capacity by way of rectangular straight slot is arranged, temperature rise is reduced.
Description
Technical field
The utility model relates to technical field of electrical components, specifically a kind of shaped grooved manganese copper diverter.
Background technique
Shunt resistance device is widely used in digital watt-hour meter, high-accuracy test instrumentation and all pairs of electric currents and surveys
In amount, the various instrument and meters for sampling, shunting, the main component of current sensor also can be used as.Shunt resistance traditional at present
Device middle section heat Relatively centralized, temperature rise are higher；And the contact resistance that the contact portion of copper-manganese piece and latten(-tin) is formed is uneven
It is even, it causes to generate heat at solder joint serious.
Utility model content
The purpose of this utility model is to provide a kind of shaped grooved manganese copper diverter, which can reduce contact electricity
Resistance, and can reduce temperature rise.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
A kind of shaped grooved manganese copper diverter, including copper-manganese piece, it is purple that the fixed T2 of electron beam welding is distinguished in copper-manganese piece two sides
Copper sheet forms alloy weld seam between copper-manganese piece and T2 copper sheet；The copper-manganese piece is longitudinally spaced to be equipped with one group of lateral rectangle
Through slot；Each T2 copper sheet is equipped with current sampling hole and voltage sampling hole.
Further, the rectangular straight slot is of same size.
Further, the width of the rectangular straight slot is not identical.
The utility model has the beneficial effects that the T2 copper sheet that setting electron beam welding is fixed, copper-manganese piece and T2 copper sheet
Between form alloy weld seam, red copper and copper-manganese come into full contact with, and reduces contact resistance, while reducing material and energy consumption；Separately
Outside, in such a way that rectangular straight slot is set, product power capacity can be effectively promoted, reduces temperature rise.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples:
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
As shown in Figure 1, the utility model provides a kind of shaped grooved manganese copper diverter, including copper-manganese piece 1,1 two sides of copper-manganese piece
The fixed T2 copper sheet 2 of electron beam welding respectively, forms alloy weld seam 3 between copper-manganese piece 1 and T2 copper sheet 2；Copper-manganese piece 1 is along longitudinal direction
It is equipped at intervals with one group of lateral rectangular straight slot 4.The width of rectangular straight slot 4 can be identical, can not also be identical.Each T2 copper sheet
Current sampling hole 2a and voltage sampling hole 2b are equipped on 2, current sampling hole 2a is shifted to install with voltage sampling hole 2b, and two sides
Current sampling hole and voltage sampling hole it is accordingly symmetrical.
The fixed T2 copper sheet of electron beam welding is set, forms alloy weld seam between copper-manganese piece and T2 copper sheet, red copper and
Copper-manganese comes into full contact with, and reduces contact resistance, while reducing material and energy consumption；In addition, passing through the side of setting rectangular straight slot
Formula can effectively promote product power capacity, reduce temperature rise.
The above descriptions are merely preferred embodiments of the present invention, not makees in any form to the utility model
Limitation；Anyone skilled in the art, it is all available in the case where not departing from technical solutions of the utility model ambit
The methods and technical content of the disclosure above makes many possible changes and modifications to technical solutions of the utility model, or is revised as
The equivalent embodiment of equivalent variations.Therefore, all contents without departing from technical solutions of the utility model, according to the utility model
Technical spirit any simple modification, equivalent replacement, equivalence changes and modification made to the above embodiment are still fallen within practical
In the range of the protection of new technique scheme.
