Abstract
A kind of plug slice and manufacture method thereof, including inserted sheet and terminals, described inserted sheet is the biplate pleated sheet adopting scale copper doubling molding, it is characterized in that: described inserted sheet doubling aftershaping has a filling chamber, filling intracavity and be equipped with the enhancing implant of metal material, described enhancing implant is iron plate or curved draw point；The invention also discloses its manufacture method。Compared with existing monolayer inserted sheet, not only save the consumption of copper, and the intensity of inserted sheet, thickness all conformance with standard, compared with the Shooting Technique of existing folded insert-piece, manufacturing process of the present invention is simple, cost is low, reinforced effects is good, is particularly suited for the big inserted sheet of lamellar。
Description
Technical field
The present invention relates to electric appliance plug pins, particularly relate to a kind of plug slice。
Background technology
The standard inserted sheet copper sheet of the appliance plug that existing general electrical equipment uses is made, every needs with copper about 13 grams, in order to save the consumption of copper, having the manufacturing process taking to be folded up by copper sheet biplate at present, the technological process that this biplate folds is: 1) blanking；2) flanging；3) molding。Though the method that this biplate folds can save copper, but there is major defect: do not reach the UL standard-required of inserted sheet thickness 2.54mm ± 0.13, the easy bending of inserted sheet insufficient strength, particularly inserted sheet root after inserted sheet extruding, very easily extrude thinning and loosening。In order to strengthen intensity and the thickness of inserted sheet, adopting the scheme of injection moulding between pleated sheet, for relatively more effective as the columned intensity increase of grounding pin class, but for the big inserted sheet of lamellar, reinforced effects is not good, and Shooting Technique is too complicated, need to improve。
Summary of the invention
To be solved by this invention primarily technical problem is that the plug slice providing a kind of intensity high, simple and practical for the above-mentioned state of the art, not only save the consumption of copper, and inserted sheet intensity, thickness all conformance with standard。
To be solved by this invention another technical problem is that and provide for the above-mentioned state of the art that a kind of intensity is high, the plug slice of technique advantages of simple, not only saves the consumption of copper, and inserted sheet intensity, thickness all conformance with standard。
This invention address that the technical scheme that above-mentioned primary technical problem adopts is: a kind of plug slice, including inserted sheet and terminals, described inserted sheet is the biplate pleated sheet adopting scale copper doubling molding, it is characterized in that: described inserted sheet doubling aftershaping has a filling chamber, fill intracavity and be equipped with the enhancing implant of metal material。
As improvement, described enhancing implant is iron plate or curved draw point, and the size of described iron plate or curved draw point is mated with filling chamber size。
Improving, described terminals are U-shaped again, are located at the afterbody of inserted sheet, and the angle being integrated blanking forming, described terminals and inserted sheet with inserted sheet is 90 degree。
Finally, described terminals be arranged over a perforation, what the other end at pleated sheet was provided with correspondence is available for the through hole that terminals place, and after described pleated sheet doubling, the bottom molding of the other end and terminals is fixed。
This invention address that the technical scheme that another technical problem above-mentioned adopts is: the manufacture method of a kind of above-mentioned plug slice, it is characterised in that:
(1) blanking, by copper sheet size blanking according to the rules, molds pleated sheet to be rolled over, and makes pleated sheet with terminals and through hole and perforation；
(2) flanging, is formed for setting the filling chamber strengthening implant on pleated sheet involutory surface to be rolled over；
(3) preforming, folds up above-mentioned pleated sheet, leaves a gap after now pleated sheet doubling, and the enhancing implant of metal material is inserted the filling intracavity in pleated sheet so that it is fixes and does not drop out；
(4) molding, pleated sheet is compressing, and the other end of pleated sheet and the bottom molding of terminals are fixed after making doubling。
Preferably, described enhancing implant is iron plate or curved draw point, and the size of described iron plate or curved draw point is mated with filling chamber size。
Compared with prior art, it is an advantage of the current invention that: adopt the mode that biplate is folding, and using iron plate or curved draw point as built-in enhancing implant, not only save the consumption of copper, and the intensity of inserted sheet, thickness all conformance with standard, compared with existing Shooting Technique, manufacturing process of the present invention is simple, cost is low, reinforced effects is good, is particularly suited for the big inserted sheet of lamellar。

Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the present invention is described in further detail。
As shown in Figure 1, a kind of plug slice, including inserted sheet 1 and terminals 2, described inserted sheet 1 is the biplate pleated sheet adopting scale copper doubling molding, described inserted sheet 1 doubling aftershaping has a filling chamber, filling intracavity and be equipped with iron plate 4 or curved draw point 5 as strengthening implant 3, the size of described iron plate 4 or curved draw point 5 is mated with filling chamber size；Described terminals 2 are U-shaped, are located at the afterbody of inserted sheet 1, are integrated blanking forming with inserted sheet 1, and the angle of described terminals 2 and inserted sheet 1 is 90 degree；Described terminals 2 be arranged over a rectangular through-holes 11, what the other end at pleated sheet was provided with correspondence is available for the through hole 12 that terminals 2 place, and after described pleated sheet doubling, the bottom molding of the other end and terminals 2 is fixed。
Manufacturing process is:
1, by scale copper size blanking according to the rules, mold pleated sheet to be rolled over, make pleated sheet with terminals and through hole and perforation, as shown in Figure 2；
2, flanging, is formed for setting the filling chamber strengthening implant, as shown in Figure 3 on pleated sheet involutory surface to be rolled over；
3, preforming, as it is shown on figure 3, leave a gap after now pleated sheet doubling, inserts in pleated sheet by iron plate 4 or curved draw point 5 so that it is fixes and does not drop out, it is simple to the operation of molding procedure；
4, molding, pleated sheet is compressing, and the other end of pleated sheet and the bottom molding of terminals are fixed after making doubling。
The thickness of the scale copper of embodiments of the invention is 0.8mm, iron plate 4 thickness is 0.9mm, the diameter of curved draw point 5 is 0.9mm, inserted sheet 1 thickness after folding forming meets the requirement of UL standard 2.54mm ± 0.13, original standard inserted sheet every copper 13 grams, every is about 8 grams with copper now, by every plug three, can saving copper about 15 grams, and adopt iron plate 4 or curved draw point 5 as strengthening implant 3, the cost of increase is few, compare Shooting Technique, the manufacturing process of the present invention is simple, and reinforced effects is good, it is easy to realize。
