Abstract
The utility model relates to an encapsulated inductor which comprises a lead frame and is characterized in that electrode blocking sheets arranged on the lead frame and a containing space is formed between the electrode blocking sheets. Irregular iron cores are arranged in the containing space, and coils are wound on the irregular iron cores. Polyester casings are distributed at the upper ends of the electrode blocking sheets, and the irregular iron cores and the coils are wrapped on the polyester casings. Therefore, no gaps exist and no noise is generated in use by adopting polyester for pouring to form the polyester casings. Simultaneously, collision resistance of products is improved. More importantly, by aid of matching between the irregular iron cores and the lead frame, connection-in in the bayonet mode can be achieved, and slanting during installation of iron core columns is avoided.
Description
Technical field
The utility model relates to a kind of inductance, relates in particular to a kind of encapsulation type inductance.
Background technology
Traditional Inductive component on the open market for the coiling assembly type, has the some shortcomings part, and such as tight when combination or wind the line when loose, this inductance can produce noise.Simultaneously, when assembling is crooked, can cause magnetic line of force offset generating magnetic leakage.And general magnetic emits and is metal shell, and frangible when product vibration or percussion, reliability is unstable, and needs labor.Appears on the market was the inductor integrally formed in the above-mentioned drawbacks considerably improved, but still have as a result of material (copper and magnetic) is not the same coefficient of expansion, and stripping the resulting stress, resulting in a slight gap will produce noise while also breakable so by touching rub.
The utility model content
The purpose of the utility model is exactly the problems referred to above that exist in the prior art in order to solve, and a kind of encapsulation type inductance is provided.
The purpose of the utility model realizes through following technical scheme:
The encapsulation type inductance; Include lead frame, wherein: described lead frame is provided with the electrode catch, constitutes spatial accommodation between the described electrode catch; Be provided with special-shaped iron core in the described spatial accommodation; Be wound with coil on the described special-shaped iron core, described electrode catch upper end is distributed with the polyester shell, and described polyester shell is enclosed with special-shaped iron core, coil.
Further, above-mentioned encapsulation type inductance, wherein: described coil end is connected with special-shaped iron core spot welding.
Further, above-mentioned encapsulation type inductance, wherein: described special-shaped iron core includes the cross base plate, and described cross base plate is provided with iron core column, and described electrode catch contacts with the cross base plate.
Further, above-mentioned encapsulation type inductance, wherein: described special-shaped iron core includes the I-shaped base plate, and described I-shaped base plate is provided with iron core column, and described electrode catch contacts with the I-shaped base plate.
Further, above-mentioned encapsulation type inductance, wherein: described special-shaped iron core includes T word base plate, and described T word base plate is provided with iron core column, and described electrode catch contacts with T word base plate.
Further, above-mentioned encapsulation type inductance, wherein: described coil is circle line coil, or described coil is the braided wire coil.
Again further, above-mentioned encapsulation type inductance, wherein: described coil twines the number of turns and is at least a circle.
The advantage of the utility model technical scheme is mainly reflected in: adopts polyester to pour into and constitutes the polyester shell, and very close to each other, make in the purposes noise can not occur.Simultaneously, improved the anticollision performance of product.What is more important relies on cooperating of special-shaped iron core and lead frame, can realize the access of a bayonet socket mode, avoids the installation of iron core column to occur crooked.
Description of drawings
The purpose of the utility model, advantage and characteristics will illustrate through the non-limitative illustration of following preferred embodiment and explain.These embodiment only are the prominent examples of using the utility model technical scheme, and all technical schemes of taking to be equal to replacement or equivalent transformation and forming all drop within the scope of the utility model requirement protection.
Fig. 1 is the organigram of lead frame;
Fig. 2 is that coil twines sketch map;
Fig. 3 is the organigram of encapsulation type inductance.
Embodiment
Encapsulation type inductance shown in Fig. 1～3 includes lead frame 1, and its unusual part is: the lead frame 1 that the utility model adopted is provided with electrode catch 2.Specifically, between electrode catch 2, constitute spatial accommodation, be provided with special-shaped iron core in this spatial accommodation.Simultaneously, on special-shaped iron core, be wound with coil 3.And electrode catch 2 upper ends are distributed with polyester shell 4, and this polyester shell 4 is enclosed with special-shaped iron core, coil 3.
With regard to the utility model one preferred implementation, for the ease of the location of coil 3 and the needs of follow-up conduction, coil 3 terminations are connected with special-shaped iron core spot welding.
Actual operating position in conjunction with the utility model; Consider and to let the good location of realization between special-shaped iron core and the electrode catch 2; Prevent skew; Can help simultaneously the guiding of coil 3 terminations, the special-shaped iron core that the utility model adopts includes cross base plate 5, and this cross base plate 5 is provided with iron core column 6.Simultaneously, make electrode catch 2 contact with cross base plate 5.
Certainly, consider that manufacturing is different with the requirement of occupation mode, in order to adapt to different production link and user demand, the special-shaped iron core that the utility model adopted also can include the I-shaped base plate.Correspondence is with it, and the I-shaped base plate is provided with iron core column 6, and electrode catch 2 contacts with the I-shaped base plate.Certainly, one can adopt T word base plate to replace the I-shaped base plate.
Further, consider the operate as normal needs of coil 3, coil 3 twines the number of turns and is at least a circle.In order to satisfy different working conditions, also can be more than Liang Quan, three circles reach.And because the difference of environment for use, the coil 3 that adopts during manufacture is circle line coil 3.Certainly, can also adopt braided wire coil 3.
Can find out through above-mentioned character express, behind employing the utility model, adopt polyester to pour into and constitute the polyester shell, very close to each other, make in the purposes noise can not occur.Simultaneously, improved the anticollision performance of product.What is more important relies on cooperating of special-shaped iron core and lead frame, can realize the access of a bayonet socket mode, avoids the installation of iron core column to occur crooked.
