Abstract
This invention discloses an improved plate inductor including a jacket, a magnetic core in it, a coil winding on the core and a base board adhered on the top surface of the core, in which, humps are set on the base board, recesses are set on the positions of the end surface of the core corresponding to the humps to be inserted into the recesses when adhering, which can strengthen the binding force of the core and the base board.
Description
Technical field
The present invention relates to a kind of improved SMT Inductor.
Background technology
Along with the develop rapidly of electronics and information industry, paster electron-like element is adopted in a large number.SMT Inductor is exactly one of them, SMT Inductor in the market includes overcoat, be provided with I-shaped magnetic core in the overcoat, be wound with coil windings on the magnetic core, one end of magnetic core is pasted with the substrate of band cross notch, four terminations welding of four pin of substrate and coil windings, because magnetic core is different with the material of substrate, their hot coefficient of dilatation is also different, therefore after the transmission that is subjected to welding heat, magnetic core and substrate are thrown off easily, thereby badly influence the quality of SMT Inductor, production firm's repousse on substrate is also arranged, to increase the contact area of magnetic core and substrate, prevent to be heated and throw off the generation of phenomenon, but produce little effect.
Summary of the invention
The objective of the invention is: a kind of improved SMT Inductor is provided, its substrate is provided with projection, the magnetic core end face is provided with groove, and projection embeds in the groove, can strengthen the adhesion of magnetic core and substrate, preventing to be heated because of welding throws off magnetic core and substrate, improves the product quality of SMT Inductor.
Technical scheme of the present invention is: a kind of improved SMT Inductor, comprise magnetic core, the coil windings on the magnetic core in the overcoat, overcoat, stick on the substrate of magnetic core upper surface, described substrate is provided with projection, the end face of magnetic core is provided with groove on the position corresponding to projection, projection embeds in the groove during stickup.
The further technical scheme of the present invention is: a kind of improved SMT Inductor, comprise magnetic core, the coil windings on the magnetic core in the overcoat, overcoat, stick on the substrate of magnetic core upper surface, described substrate is provided with projection, the end face of magnetic core is provided with groove on the position corresponding to projection, projection embeds in the groove during stickup; Described projection and groove closely cooperate, and projection is formed by the downward bending of the notch on the substrate.
The more detailed technical scheme of the present invention is: a kind of improved SMT Inductor, comprise magnetic core, the coil windings on the magnetic core in the overcoat, overcoat, stick on the substrate of magnetic core upper surface, described substrate is provided with projection, the end face of magnetic core is provided with groove on the position corresponding to projection, projection embeds in the groove during stickup; Described projection and groove closely cooperate, and projection is formed by the downward bending of the notch on the substrate; Described projection is trapezoidal, and an end that inserts groove one end big, that connect substrate is less.
Advantage of the present invention is:
1. substrate of the present invention is provided with projection, the magnetic core end face is provided with groove, and projection embeds in the groove, can strengthen the adhesion of magnetic core and substrate, prevents to be heated because of welding magnetic core and substrate are thrown off the product quality of raising SMT Inductor.
2. the projection on the substrate is formed by the downward bending in the edge of cross notch, and is trapezoidal shape, and is not only easily manufactured, and strong with the adhesion of groove, can guarantee the stickup of substrate and magnetic core firmly.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples:
Fig. 1 is a main pseudosection of the present invention;
Fig. 2 is a side cutaway view of the present invention;
Fig. 3 is a vertical view of the present invention.
Wherein: 1 overcoat; 2 magnetic cores; 3 coil windings; 4 substrates; 5 projectioies; 6 grooves; 7 notches.
Embodiment
Embodiment: as Fig. 1, Fig. 2, shown in Figure 3, a kind of improved SMT Inductor, comprise magnetic core 2, the coil windings 3 on the magnetic core 2 in the overcoat 1, overcoat 1, stick on the substrate 4 of magnetic core 2 upper surfaces, the notch 7 of described substrate 4 is bent with projection 5 downwards, the end face of magnetic core 2 is provided with groove 6 on the position corresponding to projection 5, projection 5 embeds in the groove 6 during stickup, and projection 5 closely cooperates with groove 6.
