Abstract
The utility model discloses a novel transformer framework combination which comprises a wire winding framework and a pair of magnetic cores matched with the wire winding framework. A primary needle base and a secondary needle base are arranged at the lower portions of the two ends of the wire winding framework respectively, and the position, corresponding to the secondary needle base, of the upper end of the wire winding framework is provided with a wire winding groove. The novel transformer framework combination further comprises a shell transversely installed at one end of the wire winding framework, a plurality of wire passing grooves corresponding to the wire winding groove are formed in the outer surface of the shell, the inner side of the shell is provided with a U-shaped clamping groove clamped onto the primary needle base in a matched mode, and the front end of the U-shaped clamping groove tightly butts against a magnetic core. The novel transformer framework combination enables a transformer to meet the requirements for safety distance under the condition that the size of the transformer is reduced.
Description
Technical field
The utility model relates to transformer technology field, relates in particular to a kind of Novel transformer bobbin combination.
Background technology
Transformer to safe distance requirement very strict.And electronic product is towards light, little, slim development, the space of transformer is reduced widely.This class transformer is generally adopted cabling in the raised floor to PIN pin mode.And solve safe distance scheme take exactly to lengthen bobbin Outside Dimensions and the movement outward of PIN pin met to safe distance.Although this practice can meet safe distance requirement, also increased the volume of transformer simultaneously.The skeleton combination of the utility model structure is to see through the mode that increases certain special construction shell, when safe distance is increased, also can allow the volume-diminished of transformer.
Utility model content
The utility model, in order to solve the above-mentioned deficiency of prior art, has proposed a kind of Novel transformer bobbin combination.
In order to solve the problems of the technologies described above, the utility model is by the following technical solutions: a kind of Novel transformer bobbin combination, comprise bobbin and a pair of magnetic core that is matched with bobbin, bottom, described bobbin two ends is respectively elementary needle stand and secondary needle stand, the corresponding secondary needle stand in described bobbin upper end is provided with winding slot, also comprise the shell that is laterally arranged on bobbin one end, the outer surface of described shell be provided with many described winding slots of correspondence for crossed beam trunking, and this shell inner side is provided with the U-shaped draw-in groove of snap-fit on described secondary needle stand, the front end of described U-shaped draw-in groove holds out against in described magnetic core.
In one embodiment, lower end projection three bread of described secondary needle stand enclose the U-shaped barrier wall structure of stitch.
Compared with prior art, the utility model beneficial effect is: the shell mechanism of setting is to design according to the selected core shapes of transformer, the crossed beam trunking that outer surface arranges coordinates the winding slot outlet of bobbin, on the direct stitch of lead-in wire being delivered to secondary needle stand, weld, adopt the skeleton combination of this new structure can make transformer in the situation that volume does not increase, increase safe distance, thereby allow transformer under the condition that meets characteristic, save cost and saved space, and practical, be worthy to be popularized.

Fig. 1 is explosive view of the present utility model;
Fig. 2 is structural representation of the present utility model;
Fig. 3 is the structural representation of A-A amplifier section of the present utility model;
Fig. 4 is another structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, utility model is described in detail.
As shown in Fig. 1,2,3 and 4, the Novel transformer bobbin combination the utility model proposes, comprise a pair of bobbin 1 magnetic core 2 that is matched with of bobbin 1, bobbin 1 bottom, two ends is respectively elementary needle stand 3 and secondary needle stand 4, the corresponding secondary needle stand 4 in bobbin 1 upper end is provided with winding slot 5, also comprise the shell 6 that is laterally arranged on bobbin 1 one end, the outer surface of shell be provided with many corresponding winding slots 5 for crossed beam trunking 7, and this shell inner side is provided with the U-shaped draw-in groove 8 of snap-fit on secondary needle stand 4, and the front end of U-shaped draw-in groove 8 holds out against in magnetic core 2.
The lower end of secondary needle stand 4 is also provided with corresponding barrier in the U-shaped barrier wall structure 9 of stitch.
In the utility model, the lead-in wire of transformer is walked out from the winding slot 5 of bobbin 1, is guided by crossed beam trunking 7, directly extends to bottom and is connected with the stitch of secondary needle stand 4, so just completely lead-in wire and magnetic core 2 is isolated, thereby has increased safe distance.
Wherein, the U-shaped draw-in groove 8 of shell inner side part is not only sticked in secondary needle stand 4, and front end withstands magnetic core of transformer 2, therefore in the time twining pin reason line, can carry out the assembling of shell and homonymy magnetic core simultaneously, has therefore simplified assembling flow path, has improved operating efficiency.
Further, the U-shaped barrier wall structure 9 around secondary needle stand 4 bottoms are arranged on stitch, has increased the safe distance between the stitch of secondary needle stand and the stitch of elementary needle stand.
Above-described embodiment has only been expressed several execution mode of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the utility model patent and protection range should be as the criterion with appended claims.
