CN203444907U - SMD (surface mounted device) octagonal inductor - Google Patents

Abstract

The utility model provides an SMD (surface mounted device) octagonal inductor, which comprises a base, wherein the base comprises an upper end face and a lower end face; each of the upper and lower end faces consists of a regular octagon; an enameled copper wire is arranged in a groove between the upper and lower end faces of the base; a protective layer is plated on the surface of the enameled copper wire; a guide piece is arranged on the lower end face of the base. The SMD octagonal inductor is small in size and convenient to mount; influence on the overall layout of a main board after mounting is eliminated; in addition, a function of protecting the enameled copper wire is well realized; a good induction effect is achieved during actual operation; and an electronic product can be prevented from being damaged by extra-high transient current.

Description

A kind of SMD eight limit inductance devices

Technical field

The utility model relates to inductance component field, specifically a kind of SMD eight limit inductance devices.

Background technology

Existing induction structure, mainly by manually the joint portion of coil and terminal being welded with soldering, the requirement for personnel in welding process of this operator scheme one side is high especially, personnel easily make mistakes in operation, easily there are substandard products, operating efficiency is low, on the other hand, with soldering, increased the cost of enterprise, be unfavorable for the enlarged reproduction of enterprise, existing SMD inductance device magnetic core is mostly directly outside exposed, lack corresponding protection, the thermal shock resistance that causes inductance, moisture resistance properties and anti-vibration ability are poor, cannot meet the use in practical operation.

Existing SMD inductance device is commonly square structure, and volume is larger, and takes up room while installing, and what impact was whole arranges.

Utility model content

The utility model provides a kind of SMD eight limit inductance devices; body is less; convenient installation; do not affect the integral layout of mainboard after installing; there is the effect of good protection enamel covered wire simultaneously; in practical operation, there is good inductive effects, can prevent that immediate current is excessive, cause the damage of electronic product.

The utility model comprises a kind of SMD eight limit inductance devices; comprise matrix; matrix comprises upper surface and lower surface; the end face that upper surface and lower surface consist of octagon; the upper surface of matrix and the groove part between lower surface are provided with enamel covered wire; the plated surface matcoveredn of enamel covered wire, wherein, the lower surface of matrix is provided with guide card.

Further improve, described matrix is ferrite iron core.

Further improve, described protective layer is mixed by epoxy resin and magnetic material.

Further improve, between the lower surface of described matrix and guide card, by glue, glue together linking.
