Specific embodiment

Please refer to figs. 1 to 4, that show the specific structures of the preferred embodiment of the utility model, are a kind of Network transformer and its shell structure, the shell structure include insulation shell 10 and conductive terminal 20.

Wherein: the insulation shell 10 is provided with one for assembling the winding accommodating cavity 101 of inductor winding 30, in the present embodiment In, the upper end closed of the insulation shell 10, lower end has open ports, and 10 weeks sides of insulation shell are inclined to set to form upper end phase It is narrower compared with lower end；The inductor winding 30 is set in winding accommodating cavity 101 by the open ports of lower end.The insulation shell 10 It is long in left and right ends, the short narrow width structure setting in rear and front end.Use the insulation shell 10 of such narrow width structure setting can be with So that the area of product minimizes.The conductive terminal 20 is embedded in the two sides of insulation shell 10, which is in multiple groups It is uniformly arranged；Every group of conductive terminal 20 all has the first PIN foot 21, the second PIN foot 22 and third PIN foot 23, the first PIN Foot 21 and 22 distance W1 of the second PIN foot are bigger than the distance W2 of the second PIN foot 22.Adopting the structure setting can prevent The generation the case where company's of causing tin between PIN foot, and centre cap coiling is made to have enough spaces；Second PIN foot, 22 He simultaneously Third PIN foot 23 apart from shortening as far as possible, to reach the space minimum that entire product occupies circuit board.

It says in more detail, each PIN foot all has for the outer PIN foot 201 with welding circuit board and for coiling Interior PIN foot 202.The interior PIN foot 202 is extended downwardly in the bottom of insulation shell 10, and the on both sides of the middle of the interior PIN foot 202 It is recessed with coiling recess portion 2021；The coiling recess portion 2021 of setting can prevent core wire when coiling to be easy the feelings to fall off from PIN foot Condition occurs.The outer PIN foot 201 first extends still further below outward in 10 two sides of insulation shell, and outer 201 end of PIN foot is to being folded outward Bending is at patch type weld part 2011.It is arranged by the structure that conductive terminal 20 is arranged to inside and outside PIN compared to previous integral type PIN foot the case where causing outer 201 bending deformation of PIN foot when can be avoided coiling.And 10 both ends of the insulation shell setting There is fixed part 11, which is above interior PIN foot 202 lower than outer PIN foot 201.

The network transformer, including above-mentioned shell structure and several inductor windings 30, each inductor winding 30 is installed In in winding accommodating cavity 101, the coiling of the inductor winding 30 is arranged in multicomponent cloth, and the center that every group of coiling all has two-wire is taken out Head line 301, the input line 302 of single and the output line 303 of single, the centre cap line 301 are wound in the first PIN foot 21, The input line 302 and output line 303 are wound on respectively in the second PIN foot 22 and third PIN foot 23.Specifically the inductance around Group 30 includes coil 31 and magnet ring 32, and the coil 31 and magnet ring 32 are set to winding accommodating cavity 101 in stand-type up and down It is interior.The insulation shell 10 of inductor winding 30 is put by using that can carry out to stand up and down, is facilitating 31 unification of magnet ring 32 and coil While placement, and the area that entire product occupies circuit board can be reduced.

The design focal point of the utility model is: by by conductive terminal 20 in multiple groups PIN foot structure be uniformly arranged in On insulation shell 10, every group of conductive terminal 20 all has the first PIN foot 21, the second PIN foot 22 and third PIN foot 23, and the first PIN Foot 21 is at a distance from the second PIN foot 22 than the second PIN foot 22 and third PIN foot 23 apart from bigger；Adopting the structure setting can The generation of the case where to prevent the company's of causing tin between PIN foot, and centre cap coiling is made to have enough spaces；2nd PIN simultaneously Foot 22 and third PIN foot 23 apart from shortening as far as possible, to reach the space minimum that entire product occupies circuit board.In addition each PIN foot is provided with outer PIN foot 201 and interior PIN foot 202, and outer PIN foot 201 with circuit board for being welded, interior PIN foot 202 For coiling；Outer 201 bending deformation of PIN foot is caused when can be to avoid coiling using the structure that such inside and outside PIN foot 201 is arranged.

The above descriptions are merely preferred embodiments of the present invention, not makees to the technical scope of the utility model Any restrictions, therefore any trickle amendment made by the above technical examples according to the technical essence of the present invention, equivalent change Change and modify, is still within the scope of the technical solutions of the present invention.
