Five, adopting molecule diffusion welding method, the disposable end by conduction soft ribbons welds together with a clamping plate, temperature 600-620C ° of pressure 8-10kg/cm2,, 20-25 minute heat-insulation pressure keeping time, then slowly cool down, be cooled to slowly release after room temperature；
Six, the other end step 4 of conduction soft ribbons and the method for step 5 are welded together with another clamping plate；
Seven, with step 4, step 5, step 6 method conduction soft ribbons and two installing plates are welded together；
Eight, cleaning solder side with cleaning agent, hole on clamping plate and installing plate, appearance polishes, and whole link sub-surface is tin plating, packaging warehouse-in.
During use, clamping circular arc is enclosed within transformer conducting bar upper end, tightens the gap between two panels clamping plate with bolt, clamping circular arc is fastened on transformer conducting bar；Again lead-out wire copper bar is put in the middle of two panels installing plate, copper bar has the aperture corresponding with the installing hole on installing plate, with bolt, copper bar is fastened in the middle of two panels installing plate.The present invention changes traditional hardwired mode and structure completely, and easy-to-connect, security performance are good, and owing to conduction soft ribbons has flexibility, in the transport of pre-casing type transforming station and the process of lifting, the porcelain vase not resulting in transformer conducting bar bottom breaks.

Detailed description of the invention
Below by detailed description of the invention, the detailed description of the invention is as follows:
In fig. 1 and 2: this distribution transformer low pressure is flexible coupling terminal, including clamping circular arc 1, there is two panels clamping plate 2 at clamping circular arc 1 two ends, clamping plate 2 has holes for clamping 3, clamping plate 2 is connected with conduction soft ribbons 4 one end, and conduction soft ribbons 4 other end is connected with installing plate 5, and installing plate 5 has installing hole 6.
This distribution transformer low pressure is flexible coupling the manufacture method of terminal, it is characterised in that step is as follows:
One, choosing calendering copper soft ribbons and calendering copper material, their section shape and size meets the requirement of safety design current；
Two, calendering copper material entirety is pressed into the shape of clamping circular arc 1 and clamping plate 2, makes two installing plates 5 with calendering copper material, make 2 conduction soft ribbons 4 by calendering copper soft ribbons；
Three, by hard for the length pressure of conduction soft ribbons 4 two ends 6mm, Baltimore groove, spill groove depth 6mm, the cross section of Baltimore groove and the cross section of clamping plate 2, installing plate 5 are made equal；
Four, an end of pickling conduction soft ribbons 4, wraps the thick Xi Bo of 0.5mm by the end of clamping plate 2, as scaling powder, inserts in the Baltimore groove of conduction soft ribbons 4 end with pressure,
Five, adopting molecule diffusion welding method, the disposable end by conduction soft ribbons 4 welds together with a clamping plate 2, temperature 610C ° of pressure 10kg/cm2,, 25 minutes heat-insulation pressure keeping time, then slowly cool down, be cooled to slowly release after room temperature；
Six, the other end step 4 of conduction soft ribbons 4 and the method for step 5 are welded together with another clamping plate 2；
Seven, with step 4, step 5, step 6 method conduction soft ribbons 4 and two installing plates 5 are welded together；
Eight, cleaning solder side with cleaning agent, hole on clamping plate 2 and installing plate 5, appearance polishes, and whole link sub-surface is tin plating, packaging warehouse-in.
When producing in a large number, aforementioned production method inefficiency, following particular manufacturing craft can be adopted to carry out on molecule diffusion welding machine: the structure of this molecule diffusion welding machine is as shown in Figure 3, in figures 4 and 5, this particular manufacturing craft includes an installation bed being fixed between seaming chuck 2 and push-down head 1, bed is installed while being round bar 11, another side is a flat board 12, by clamping plate, after conduction soft ribbons and installing plate are installed together, clamping circular arc is enclosed within round bar 11, flat board 12 is through in the middle of two conduction soft ribbons, conduction soft ribbons top is top die 13, two briquettings 14 of top die 13 bottom are positioned at conduction soft ribbons two ends, top die 13 is fixed on seaming chuck 2, conduction soft ribbons bottom is dip mold 15, dip mold 15 is fixed on push-down head 1.
Before welding, many to be welded terminals that are flexible coupling are arranged on installation bed, what a presses be flexible coupling after terminal, the terminal that is flexible coupling pressed is pushed out along the longitudinal direction of round bar, the next to be welded terminal that is flexible coupling is allowed to enter between upper dip mold, carry out pressure welding, so circulate, continuously perform, welding temperature can be properly increased, or increase welding pressure, to shorten weld interval, improves production efficiency.
