Summary of the invention
The utility model provides a kind of stressed even, constitutionally stable whole plane formula arm-tie folder structure to the problems referred to above.
Technical scheme according to the utility model: a kind of whole plane formula arm-tie folder structure; Comprise upper clamping piece, lower clamping piece and arm-tie; The cross section of said upper clamping piece and said lower clamping piece is a flute profile, and the two ends of said arm-tie are provided with dop, has the draw-in groove that is complementary with said dop shape on the web of said upper clamping piece and said lower clamping piece; After said dop was connected in said draw-in groove, said arm-tie and said upper clamping piece and said lower clamping piece were affixed on the same plane unshakable in one's determination.
Said dop and said draw-in groove be shaped as T shape.
The both sides at said arm-tie two ends have the breach of symmetry, and the end of said breach and said arm-tie forms said dop.
Said breach is trapezoidal.
Said upper clamping piece and said lower clamping piece are formed by the steel plate flanging.
The width of the bottom wing listrium of said upper clamping piece is greater than the width of its top flange plate, and the width of the top flange plate of said lower clamping piece is greater than the width of its bottom wing listrium.
Have vertical elongated slot on the said arm-tie.
Said arm-tie has three, has three said draw-in grooves on said upper clamping piece and the said lower clamping piece.
The technique effect of the utility model is: the utility model is provided with dop at the two ends of arm-tie; The dop at arm-tie two ends adopts the mode of inlaying to be connected in the draw-in groove of upper clamping piece and lower clamping piece; Arm-tie and upper clamping piece and lower clamping piece are affixed on the same plane unshakable in one's determination; Make folder more steady to the contact-making surface of iron core, better to bundle folder effect of iron core; Reduced the difficulty of processing of the insulating material of middle filling usefulness.The utility model assembling is simple, and efficiency of assembling unshakable in one's determination is high.

Embodiment
Be further described below in conjunction with the embodiment of accompanying drawing the utility model.
Among Fig. 1 ~ Fig. 8, comprise draw-in groove 1, lower clamping piece 2, upper clamping piece 3, dop 4, arm-tie 5, iron core 6, elongated slot 7, breach 8 etc.
As shown in Figure 1; The utility model is a kind of whole plane formula arm-tie folder structure, and stem unshakable in one's determination is axially reinforced, and laminated core is clamped reinforce into a magnetic circuit integral body; Preventing that yoke seam up and down unshakable in one's determination is stressed brings damage for seam crossing unshakable in one's determination, thereby influences the increase of core loss.It comprises upper clamping piece 3, lower clamping piece 2 and arm-tie 5.Arm-tie 5 has three.
Like Fig. 2～shown in Figure 4, the cross section of lower clamping piece 2 is a flute profile, is formed by the steel plate flanging, and the width of its top flange plate is greater than the width of its bottom wing listrium.The web top edge of lower clamping piece 2 has three draw-in grooves 1 that are shaped as T shape.
Like Fig. 5～shown in Figure 7, the cross section of upper clamping piece 3 also is a flute profile, is formed by the steel plate flanging.Upper clamping piece 3 and lower clamping piece 2 symmetries, the width of the bottom wing listrium of upper clamping piece 3 is greater than the width of its top flange plate.The web lower limb of upper clamping piece 3 also has three draw-in grooves 1 that are shaped as T shape.Draw-in groove 1 can form through laser cutting.
As shown in Figure 8, arm-tie 5 is that strip is dull and stereotyped, and the both sides at its two ends have the breach 8 of symmetry, and breach 8 is preferably trapezoidal, can certainly be other shape, such as rectangle or semicircle.The end of breach 8 and arm-tie 5 forms the dop 4 of T shape, and dop 4 is complementary with the shape of draw-in groove 1, forms public mother and cooperates.Also have vertical elongated slot 7 on the arm-tie 5, can reduce eddy current loss.
Again referring to Fig. 1; After the dop 4 at arm-tie 5 two ends is connected in the draw-in groove 1 of upper clamping piece 3 and lower clamping piece 2; Dop 4 is embedded in the draw-in groove 1, and arm-tie 5 is affixed on the same plane of iron core 6 with upper clamping piece 3 and lower clamping piece 2, has solved traditional folder effectively to the unstable situation of iron core pressurization; Make folder more steady to unshakable in one's determination 6 contact-making surface, better to unshakable in one's determination 6 bundle folder effect; Reduced the difficulty of processing of the insulating material of middle filling usefulness, middle insulating part processing becomes simpler, easy operating, and this structure is to the better adaptability of the insulating material of centre filling.
The utility model assembling is simple, and efficiency of assembling unshakable in one's determination is high, has stopped the phenomenon of doing over again.
