Summary of the invention
The purpose of this utility model is to provide a kind of withstand voltage respond well transformer for the deficiencies in the prior art, the utility model is by improving transformer device structure, effectively solve the problem that transformer exists, promoted the withstand voltage effect of transformer, practical.
For achieving the above object, a kind of withstand voltage respond well transformer of the present utility model, comprise skeleton, described skeleton is provided with magnetic core hole, magnetic core is provided with magnetic core in hole, described skeleton is provided with elementary winding slot and secondary rolling thread groove, described elementary winding slot is provided with primary coil, described secondary rolling thread groove is provided with secondary coil, described elementary winding slot and secondary rolling thread groove are provided with several pins, described elementary winding slot is also provided with and vertically disposed the first wrapping post of pin, described secondary rolling thread groove is also provided with and vertically disposed the second wrapping post of pin, the width T of described secondary rolling thread groove is more than or equal to 6mm.
As preferably, the cross section of described the first wrapping post and the second wrapping post is circle, and the diameter of described the first wrapping post and the second wrapping post is 2mm, and the height of described the first wrapping post and the second wrapping post is 2mm.
As preferably, the width of described secondary rolling thread groove is 8mm.
As preferably, described the first wrapping post and elementary winding slot are one-body molded, and described the second wrapping post and secondary rolling thread groove are one-body molded.
As preferably, described skeleton is arranged with protective sleeve, and described protective sleeve is provided with the buckle closure being fastened and connected with it.
The beneficial effects of the utility model: by setting up the first wrapping post and the second wrapping post, extended the length of enamelled wire, need not add Teflon sleeve pipe, also can normally carry out wicking operation, and wrapping post is designed to cylindrical, even if service time is the long phenomenon that also there will not be enamelled wire to snap again, define the altitude range of the first wrapping post and the second wrapping post, make the insulation distance between elementary winding slot and secondary rolling thread groove keep best, do not need to add insulating sleeve, simplify production process, enhance productivity; By limiting the width of secondary rolling thread groove, distance between pin on secondary rolling thread groove and the pin on elementary winding slot is increased, the line that secondary rolling thread groove is pulled out is first walked around the second wrapping post, again on pin, make the safe distance between elementary winding slot and secondary rolling thread groove reach standard, avoided the bad defect of high pressure, in actual production process, remove this operation of fly line, improved production efficiency.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
As shown in Figures 1 to 5, a kind of withstand voltage respond well transformer, comprise skeleton 1, described skeleton is provided with magnetic core hole 11, in magnetic core hole 11, be provided with magnetic core, described skeleton 1 is provided with elementary winding slot 12 and secondary rolling thread groove 13, described elementary winding slot 12 is provided with primary coil, described secondary rolling thread groove 13 is provided with secondary coil, described elementary winding slot 12 and secondary rolling thread groove 13 are provided with several pins 2, described elementary winding slot 12 is also provided with and vertically disposed the first wrapping post 121 of pin 2, described secondary rolling thread groove 13 is also provided with and vertically disposed the second wrapping post 131 of pin 2, the width T of described secondary rolling thread groove 13 is more than or equal to 6mm.
The present embodiment is by setting up the first wrapping post 121 and the second wrapping post 131, and the length that has extended enamelled wire, need not add Teflon sleeve pipe, also can normally carry out wicking operation; By limiting the width of secondary rolling thread groove 13, distance between pin 2 on secondary rolling thread groove 13 and the pin on elementary winding slot 12 is increased, the line that secondary rolling thread groove 13 is pulled out is first walked around the second wrapping post 131, again on pin 2, make the safe distance between elementary winding slot 12 and secondary rolling thread groove 13 reach standard, avoided the bad defect of high pressure, in actual production process, remove this operation of fly line, improved production efficiency.
