Embodiment
Detailed description of the present utility model and technology contents, now just coordinate accompanying drawing to be described as follows:
In order to illustrate the utility model, avoid the enforcement structure of the deteriorated coil holder of wire insulation, the utility model is mainly to give an example with bottom view and the end view of described coil holder in this.Refer to Fig. 2 and Fig. 3, coil holder described in the utility model consists predominantly of a winding section 1, and at least one outlet portion 2 that extends described winding section 1 one sides.Wherein, described winding section 1 can supply at least one coil windings 3 windings wherein, and described coil windings 3 can be formed by insulation wire rod institute coiling.And the another side of described outlet portion 2 relatively described winding sections 1 is provided with a plurality of pins 23, and further defining described winding section 1 is an axial A1 with described pin 23, and in described outlet portion 2 relatively described axial A1 with two horizontal A2 separately, at least one the first steering column 21 and at least one the second steering column 22 that A3 arranges, more specifically explanation, horizontal A2 described in the utility model, it is parallel that A3 is, and vertical with described axial A1, so, described in each, the first steering column 21 is adopted interval setting along described horizontal A2, described in each, 21 of the first steering columns are adopted interval setting along described horizontal A3, in other words, described in each, the first steering column 21 is to be to be staggered front to back setting with the second steering column 22 described in each.Accordingly, when described coil windings 3 coilings complete, one winding end 31 of described coil windings 3 extends to described outlet portion 2, after described the first steering column 21 and described the second steering column 22, forms one and is greater than the bending angle C1 of 90 degree and is connected on described pin 23.Thus, because the guiding of described the first steering column 21 and the second steering column 22 makes described winding end 31 turn to by the periphery along described the second steering column 22 through described the first steering column 21, just can be in succession on described pin 23, make the end 31 of described coil windings 3 form described bending angle C1, and so-called described bending angle C1 is that described winding end 31 is with respect to the angle of pin 23.The described bending angle C1 of wide-angle can specifically avoid the wire rod insulating barrier coated because overflexing makes that the deteriorated problem of be full of cracks occurs.Moreover, outlet described in the utility model portion 2 can further be applied to one end of transformer winding primary coil, in addition, the utility model has an iron core support face 25 arranging for iron core (this figure does not show) in the opposite side of described outlet portion's 2 corresponding described those first steering columns 21 and described the second steering column 22.
Refer to again Fig. 3, further, outlet described in the utility model portion 2 has more a described winding section 1 of connection and has the lead-in wire inclined-plane 24 of a default angle C2 with described axial A1, and the use that described lead-in wire inclined-plane 24 is set is intended to, described coil windings 3 completes in the process of extending to described outlet portion 2 in coiling, still likely produce the bending angle that approaches 90 degree, cause wire rod generation insulation degradation, described lead-in wire inclined-plane 24 can make described winding end 31 extend to described outlet portion 2 with the bent radian of comparatively level and smooth circle, and then the generation addressing the above problem.More specifically explanation, alleged its angle of described default angle of the utility model can be greater than 20 degree, further, can be greater than 20 degree and be less than or equal to 45 degree.
Moreover, the utility model is in Fig. 2 embodiment, described coil holder only has single described outlet portion 2, described winding section 1 opposite side that is relatively set with described outlet portion 2 can arrange a wire connecting portion 4, and so-called wire connecting portion 4 in fact as the set leading-out terminal (meaning to be provided with a plurality of positions of drawing angle) of transformer coil holder identical, but the utility model embodiment, not as limit, the both sides of described winding section 1 can be respectively arranged with an outlet portion 2, 2a, and outlet portion 2, 2a can be respectively for armature winding and the secondary winding outlet of transformer, as shown in Figure 4.
In sum, the deteriorated coil holder of wire insulation of avoiding described in the utility model, is mainly comprised of a winding section and at least one outlet portion.Described winding section is at least one coil windings winding, described outlet portion extends a side of described winding section, and the another side of relatively described winding section is provided with a plurality of pins, define described winding section and described pin and be one axial, and relatively described axially with at least one the first steering column and at least one second steering column of two interval horizontally sets in described outlet portion, the end that makes described coil windings is greater than 90 degree and is connected in described pin by a bending angle of the first steering column and the second steering column.By this, excessive to overcome existing outlet bending angle, and the easy problem that produces insulation Material degradation.
Certainly; the utility model also can have other various embodiments; in the situation that not deviating from the utility model spirit and essence thereof; those of ordinary skill in the art are when making various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the utility model.
