Embodiment
For above-mentioned purpose of the present utility model, feature and advantage can be become apparent, below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.At first need to prove, the utility model is not limited to following embodiment, those skilled in the art should understand the utility model from the spirit that following execution mode embodies, and each technical term can be done the most wide in range understanding based on Spirit Essence of the present utility model.Same or analogous member uses the same reference numerals to represent among the figure.
Consult Fig. 3, Fig. 4 and Fig. 5, the electronic installation of the utility model the first preferred embodiment comprises a terminal base 2, and several coils 3.
This terminal base 2 comprises a hollow and has a pedestal 21 of being located at the opening 211 in the outside, and several stretch out at each interval this pedestal 21 outward and are positioned at this opening 211 lead foot 22 on every side.This pedestal 21 is made by the insulated plastic glue material, and has a slice level and rectangular basal wall 212, and a slice is gone out the perisporium 213 of this opening 211 by the upright past extension of these basal wall 212 peripheries and ora terminalis boundary.This basal wall 212 matches with this perisporium 213 and defines an installing space 214.And this perisporium 213 has two assembly wall sections 215 that the interval is relative.Described lead foot 22 is all made by conductive metallic material, and is plugged in respectively at each interval described assembly wall section 215.For clear expression structure, in present embodiment shown in the drawings, make the outside of this pedestal 21 up, namely this opening 211 is to be positioned at the top side, the setting party of this terminal base 2 is to being subject to this certainly, for example can spin upside down or the left and right sides edge-on.
Described coil 3 is installed on respectively in the installing space 214 of this pedestal 21, and each coil 3 all comprises an iron core 31, and circle is around in the wire 32 that this iron core 31 and two ends are connected to respectively wherein two lead foots 22 of described lead foot 22.This iron core 31 has a circle coiled hollow ring and has the external annulus 312 of the relative side wall section 311 in two intervals, and one be arranged in that these external annulus 312 central authorities and consubstantiality connect described side wall section 311 connect wall 313, for clear expression, in Fig. 5 with two imaginary lines 310 separate out this external annulus 312 with should in connect wall 313.This external annulus 312 with should in connect wall 313 and match and define two annular distances 314 separately.This external annulus 312 is oval ring, has a long axis (not shown) that intersects vertically, and a minor axis 315, and this minor axis 315 by described side wall section 311 and should in connect wall 313.The all rounded and equal diameters of described annular distance 314.Certainly on implementing, the shape of this external annulus 312 and described annular distance 314 also can change, be not limited with present embodiment, for example described annular distance 314 can be ellipse, or this external annulus 312 can be circular and described annular distance 314 can be circle or ellipse, or this external annulus 312 can be rectangle and described annular distance 314 can be circle or ellipse, or this external annulus 312 can be rectangle and described annular distance 314 is square or rectangular etc.And these wire 32 circles connect wall 313 peripheries in this iron core 31.Certainly this wire 32 can be kneaded to pool capital by several wires and form, and the quantity of this wire 32 also can increase on implementing, and no longer illustrates at this.In addition, this electronic installation can also comprise several lines 4 that encloses respectively 312 of external annulus that are around in per two adjacent iron cores 31, and just it is general technology, so in this also no longer explanation.
During assembling, each root wire 32 circles are connected wall 313 peripheries in separately iron core 31, and with each root line 4 circles around 312 of the external annulus of the iron core 31 of per two adjacent windings 3, again described coil 3 is placed in the installing space 214 of this pedestal 21, and described wire 32 do not intersected be wrapped in respectively intrusively on the corresponding lead foot 22, then carry out again zinc-plated operation, so as to being electrically connected each coil 3 and corresponding lead foot 22 thereof.Certainly, also can be used for the described coil 3 of fixing protection in these pedestal 21 interior filling one deck insulator (not shown), again a slice lid (not shown) is sealed on the opening 211 of pedestal 21 at last, so that above-mentioned Component encapsulating is combined into one.
Consult Fig. 6, the structure of the second preferred embodiment of the utility model electronic installation is approximately identical to the first preferred embodiment, comprise equally a terminal base 2, and several are installed on respectively the coil 3 in this terminal base 2, difference is in part: the structure of the terminal base 2 of present embodiment is different, and the described lead foot 22 of this terminal base 2 stretches out respectively this pedestal 21 away from a side of this opening 211.That is to say that above-mentioned coil 3 can be installed in the terminal base 2 of various different kenels, is not limited with present embodiment and the first embodiment.
In sum, the utility model electronic installation is to make the iron core 31 of each coil 3 all be provided with this two annular distances 314, and the radius less of each annular distance 314 is in the annular distance 122 of existing coil 12 shown in Figure 2, and allow this wire 32 circles be around in this iron core 31 in connect wall 313, so can produce two circles respectively around the magnetic circuit of described annular distance 314 and opposite direction, the formed inductance of described parallel circuits will addition, and the length of magnetic path less that respectively encloses magnetic circuit is in the length of magnetic path of existing coil 12 shown in Figure 2, so in the constant situation of the number of turns of the number of turns of this wire 32 and the existing coil 12 of Fig. 2, the utility model really can effectively increase the inductance value of each coil 3, thus, when the utility model is implemented, also can be under the condition that does not reduce inductance value, relatively reduce the number of turns of this wire 32, so that processing operation, promote and make efficient, in addition, more owing to wire 32 circles of the present utility model connect on the wall 313 around being arranged in these iron core 31 central authorities, and do not enclose around being positioned on this iron core 31 external annulus 312 on every side, so the magnetic flux of its generation can be limited in this iron core 31 fully, and can not spill outside this iron core 31, so can relatively improve inductance value, so really can reach the purpose of this utility model.
Should be understood that those skilled in the art can make various changes or modifications the utility model after having read above-mentioned instruction content of the present utility model, these equivalent form of values fall within the application's appended claims limited range equally.
