Description
Technical field
The utility model relates to a kind of high current lug plates, belong to transformer technology field.
Background technique
High current lug plate be transformer manufacturing during, the common frame mode of low-voltage lead, general structure and work
Skill technology are as follows: lug plate group is constituted by multi-disc 0.3mm thickness T3 copper sheet as needed, then connecting pin by ward off tin be bonded to it is whole
After body, then the manufacturing process for commonly warding off tin high current lug plate is completed through flush, punching, whole process is complex, when production
Between it is long, production efficiency is low, especially ward off process of tin process generation exhaust gas, waste liquid human body and environment are caused centainly to injure,
It is often difficult to become the old problem of puzzlement enterprise development by environmental impact assessment.And ward off tin process and be affected by human factors, high current wiring
Piece wards off tin poor quality control, is easy to appear phenomena such as running tin and slag inclusion.It runs tin and mainly causes to ward off tin size and do not meet design and want
It asks, causes molding assembly difficulty in transformer lead assembling process, slag inclusion is even more hidden danger of quality, may cause transformer in operation
Safety accident occurs.
Summary of the invention
The purpose of this utility model is to provide a kind of high current lug plate, which accomplishes that structure is simple,
Convenient for operation, the hidden danger of quality being likely to occur is eliminated, improves reliability.
The utility model to achieve the goals above, adopts the following technical scheme that
A kind of high current lug plate, in-between section are lug plate group, are connected with tin plating square type copper at the both ends of lug plate group
Pipe；
Punching hole is provided on tin plating square type copper pipe.
Further, the copper pipe wall thickness of the tin plating square type copper pipe is 1mm, caliber size are as follows: the first side side length A × second
Long B is equal to lug plate group nominal sectional dimension: third side length C+0.5 × the 4th side length D+0.5；
First side length A, the second side length B, third side length C and the 4th side length D unit be millimeter.
Further, the lug plate group is thick by multi-disc 0.3mm, the copper belt composition of third side length C mm wide.
After tin plating square type copper pipe and the assembling of lug plate group, by stamping equipment and punching pressure die, to connecting portion to rush
Pressure mode forms, and completes the manufacturing process of high current lug plate；
A kind of high current lug plate carried out respective electric, mechanical test during invention, met GB/T
9327.2-2008 " cable conductor compression and mechanical connecting joint test method D.C. resistance test method ", GB/T 9327.3-
2008 " cable conductor compression and mechanical connecting joint test method short-circuit test methods ", GB/T 9327.4-2008 " cable
Conductor compression and mechanical connecting joint test method thermal cycling test method " requirement.
The utility model has the advantages that
1, the utility model structure is simple, is easy production, effectively improves labor productivity；
2, the utility model quality is stablized, high reliablity: it eliminates the slag inclusion after warding off tin and wards off the race tin of tin process appearance,
It causes to ward off tin size and the hidden danger of quality such as is difficult to control；
3, the utility model solves high current lug plate junction and wards off tin treatment process process waste gas, waste liquid outlet, right
It is injured caused by environment and health of human body.
Detailed description of the invention
Fig. 1 is a kind of high current lug plate schematic diagram；
Fig. 2 is tin plating square type copper pipe (1) schematic diagram；
Fig. 3 is lug plate group (2) schematic diagram；
Fig. 4 is the overhead view of Fig. 1.
Specific embodiment
1,2,3,4 pair of the utility model is described in detail with reference to the accompanying drawing:
A kind of high current lug plate, in-between section are lug plate group 2, are connected with tin plating square type at the both ends of lug plate group 2
Copper pipe 1；
Punching hole 1-1 is provided on tin plating square type copper pipe 1.
The copper pipe wall thickness of the tin plating square type copper pipe 1 is 1mm, caliber size are as follows: the first side length of side length A × second B is equal to
2 nominal sectional dimension of lug plate group: third side length C+0.5 × the 4th side length D+0.5；
First side length A, the second side length B, third side length C and the 4th side length D unit be millimeter.
The lug plate group 2 is thick by multi-disc 0.3mm, the copper belt composition of third side length C mm wide.
After tin plating square type copper pipe 1 is assembled with lug plate group 2, by stamping equipment and punching pressure die, to connecting portion with
Impact style forms (pressing direction 5), completes the manufacturing process of high current lug plate.
