Abstract
The utility model discloses a EC magnetic core structure, comprising a magnetic core middle column (1) and magnetic core supporting legs (2)distributed on both sides of the magnetic core middle column (1), the window size of the magnetic core is 30.71cm, the inner chamfer of the magnetic core supporting legs (2) is R2.1cm, the surface that the magnetic core supporting legs (2) towards the magnetic core middle column (1) is R16.15cm and a tangent plane of R2.1cm, the minimum width of the outside of the magnetic core supporting legs (2) to the R16.15cm is 5.65cm, the lateral distance of the two side magnetic core supporting legs (2) is 43.3cm. In the EC magnetic core structure, the original 29.07cm of the window size of the magnetic core is extended to 30.71cm, the original R0.5cm of the chamfer of the magnetic core supporting legs is extended to R2.1cm, the assembly requirement of the large size line package is satisfied, at the same time, the width of the two supporting legs is changed from 5.5cm to5.65cm, the effective area of the magnetic core is increased, the performance of the magnetic core is improved.
Description
Technical field
The utility model relates to the magnetic core technical field, relates in particular to a kind of EC core structure that is used for transformer.
Background technology
Magnetic core; Be applied in the coil or transformer of various electronic equipments, as depicted in figs. 1 and 2, be respectively the front view and the vertical view of EC43 magnetic core in the prior art; The EC43 magnetic core comprises magnetic core intermediolateral column 1 and is distributed in the magnetic core limit leg 2 of magnetic core intermediolateral column 1 both sides that the line bag is arranged on the magnetic core intermediolateral column 1.The size of windows of magnetic cores shown in the figure 29.07 in order to satisfy the performance requirement of transformer, can only dispose the line bag of relative specification.When line bag specification enlarged, current windows of magnetic cores size was less than normal, influences its assembly manipulation.In order to adapt to the assembling of big gauge wire bag, need to increase the windows of magnetic cores size, and the overall structure of magnetic core is made accommodation, to satisfy the overall structure requirement of transformer.
The utility model content
To above defective, the utility model provides a kind of EC core structure, increased the windows of magnetic cores size, satisfied the matching requirements of big gauge wire bag.
For realizing above-mentioned purpose, the utility model is realized through following technical scheme:
A kind of EC core structure comprises the magnetic core intermediolateral column and is distributed in the magnetic core limit leg of magnetic core intermediolateral column both sides that windows of magnetic cores is of a size of 30.71cm, and the chamfering that magnetic core props up inboard leg is R2.1cm.
Preferably, the face that the magnetic core supporting leg is met to the magnetic core intermediolateral column is the tangent plane mutually of R16.15cm and R2.1cm, and it is 5.65cm that magnetic core props up leg outer side to the minimum widith of R16.15cm.
Preferably, the outer lateral extent of both sides magnetic core limit leg is 43.3cm.
Compared with prior art, the utlity model has following beneficial effect:
In the utility model; Expand the windows of magnetic cores size to 30.71cm by original 29.07cm; The chamfering that the magnetic core supporting leg is met to the magnetic core intermediolateral column expands R2.1cm to by original R0.5cm, has satisfied the matching requirements of big gauge wire bag, and the width with two limit legs becomes 5.65cm by 5.5cm simultaneously; Increased the effective area of magnetic core, the serviceability of the magnetic of improvement.
Description of drawings
According to embodiment and accompanying drawing the utility model is done further explain below.
Fig. 1 is the front view of a kind of EC core structure in the prior art.
Fig. 2 is the vertical view of a kind of EC core structure in the prior art.
Fig. 3 is the front view of a kind of EC core structure of the utility model proposition.
Fig. 4 is the vertical view of a kind of EC core structure of the utility model proposition.
Embodiment
Like Fig. 3 and shown in Figure 4, be respectively the front view and the vertical view of a kind of EC core structure of the utility model proposition.With reference to accompanying drawing, a kind of EC core structure that the utility model proposes comprises magnetic core intermediolateral column (1) and is distributed in the magnetic core limit leg (2) of magnetic core intermediolateral column (1) both sides that windows of magnetic cores is of a size of 30.71cm, and the inboard chamfering of magnetic core supporting leg (2) is R2.1cm.The face that magnetic core supporting leg (2) is met to magnetic core intermediolateral column (1) is the tangent plane mutually of R16.15cm and R2.1cm, and magnetic core supporting leg (2) outside to the minimum widith of R16.15cm is 5.65cm.The outer lateral extent of magnetic core limit, both sides leg (2) is 43.3cm.
In the utility model technical scheme; Through core structure of the prior art is improved, expand the windows of magnetic cores size to 30.71cm by original 29.07cm, the chamfering that the magnetic core supporting leg is met to the magnetic core intermediolateral column expands R2.1cm to by original R0.5cm; The matching requirements of big gauge wire bag have been satisfied; Width with two limit legs becomes 5.65cm by 5.5cm simultaneously, has increased the effective area of magnetic core, the serviceability of the magnetic of improvement.
Combine accompanying drawing that the utility model has been carried out exemplary description above; Obviously the realization of the utility model does not receive the restriction of aforesaid way; As long as adopted method design of the utility model and the various improvement that technical scheme is carried out; Or the design of the utility model and technical scheme are directly applied to other occasion without improving, all in the protection range of the utility model.
