The utility model discloses a low voltage coil's copper bar and connection structure of copper foil, processing is simple and easy, and is with low costs, need not the electric welding, has advantages such as no crator welding slag, resistance are little.
Description
Technical field
The utility model relates to a kind of copper bar of low-voltage coil and the syndeton of Copper Foil, belongs to transformer manufacture technology.
Background technology
Please participate in Fig. 1, when low-voltage coil wire is Copper Foil, the place of lifting one's head adopts copper bar 1' to be connected with Copper Foil 2', and prior art is connected with the common electric welding of Copper Foil 2' by copper bar 1'.Manual welding error is comparatively large, and crator 3' is uneven, and this technology, by ambient temperature, humidity effect, sealing-off, rosin joint, bubble phenomenon easily occurs, causes welding kesistance excessive, local overheating etc. in running.Manually polish in process after welding, welding slag easily enters coil inside, causes damage in insulation, partial short-circuit etc.
Utility model content
The purpose of this utility model, provides a kind of copper bar of low-voltage coil and the syndeton of Copper Foil exactly in order to solve the problem, adopt and press connection, process simple and easy, cost is low, without the need to electric welding, has without advantages such as crator welding slag, resistance are little.
The purpose of this utility model is achieved in that
A kind of copper bar of low-voltage coil of the present utility model and the syndeton of Copper Foil, described Copper Foil is arranged on the top of described copper bar, the right part of the lower surface of described Copper Foil contacts with the upper surface of described copper bar and arranges, described Copper Foil is connected by pressing with copper bar, and the position that described Copper Foil contacts with described copper bar is provided with and somely presses connecting portion;
Described some connecting portions that presses are matrix arrangement, and often adjacent two press the radial of connecting portion and are spaced apart 20-30mm, and often adjacent two axially spaced-aparts pressing connecting portion are 50-80mm;
Each on described Copper Foil presses connecting portion all to lower recess, and eachly presses connecting portion is 1/2-2/3 from the thickness of described copper bar to the degree of depth of lower recess;
Described each bottom pressing connecting portion does not penetrate described Copper Foil.
Above-mentioned a kind of copper bar of low-voltage coil and the syndeton of Copper Foil, wherein, described in press connecting portion number be 27, these 27 press the matrix forms that connecting portion is arranged in 9 row, 3 row; Be spaced apart radial interval between adjacent two row, radial spacing distance is 20-30mm; Be spaced apart axially spaced-apart between two adjacent row, the distance of axially spaced-apart is 50-80mm.
Above-mentioned a kind of copper bar of low-voltage coil and the syndeton of Copper Foil, wherein, without protruding on the lower surface of described copper bar.
The copper bar of low-voltage coil of the present utility model and the syndeton of Copper Foil, compared with connecting with traditional electric welding, beneficial effect is: copper bar and Copper Foil contact-making surface are evenly pressed, copper bar is effectively connected with Copper Foil, welding slag, wedge angle etc. can not be produced, this technical operation is simple, with low cost, effectively improves transformer performance.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the copper bar of prior art mesolow coil and the syndeton of Copper Foil;
Fig. 2 is the schematic diagram of the copper bar of low-voltage coil of the present utility model and the syndeton of Copper Foil;
Fig. 3 is the schematic diagram of the copper bar of the low-voltage coil of utility model and the process that presses of Copper Foil.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Refer to Fig. 2, there is shown the copper bar 1 of low-voltage coil of the present utility model and the syndeton of Copper Foil 2, Copper Foil 2 is arranged on the top of copper bar 1, the right part of the lower surface of Copper Foil 2 contacts with the upper surface of copper bar 1 and arranges, Copper Foil 2 is connected by pressing with copper bar 1, and the position that Copper Foil 2 contacts with copper bar 1 is provided with and somely presses connecting portion 21; Some connecting portions 21 that presses arrange in matrix, and often adjacent two the radial interval a pressing connecting portion 21 are 20-30mm, and often adjacent two the axially spaced-apart b pressing connecting portion 21 are 50-80mm; Each connecting portion 21 that presses on Copper Foil 2 all to lower recess, and eachly presses connecting portion 21 is 1/2-2/3 from the thickness of copper bar 1 to the degree of depth of lower recess; Each bottom pressing connecting portion 21 does not penetrate Copper Foil 2.Without protruding on the lower surface of copper bar 1
Preferably, the number pressing connecting portion 21 is 27, and these 27 press the matrix form that connecting portion 21 is arranged in 9 row, 3 row; Be spaced apart radial interval a between adjacent two row, radial interval a distance is 20-30mm; Be spaced apart axially spaced-apart b between two adjacent row, the distance of axially spaced-apart b is 50-80mm.
