Abstract

A package structure for an inductance element is provided. The package structure comprises a casing, a plurality of conductive terminals, a lid, and a positioning device. The casing has two opposite first sidewalls and two opposite second sidewalls, all of which define a receiving space for receiving the inductance element. Each conductive terminal has an upper end and a lower end. The upper ends extend from an upper portion of one of the first sidewalls, and are located in a recess defined by the two opposite second sidewalls to electrically connect to the inductance element. The lower ends extend from a lower portion of the first sidewalls and are adapted to electrically connect to a circuit board. The lid is configured to cover the inductance element. The positioning device is disposed between the lid and at least one of the first sidewalls to position the lid onto the casing.

Claims

1. A package structure for use in an inductance element, comprising:

a casing having two opposite first sidewalls and two opposite second sidewalls, all of which defining a receiving space for receiving the inductance element;

a plurality of conductive terminals, each having an upper end and a lower end, the upper end extending from an upper portion of one of the first sidewall and being located in a recess defined by the two opposite sidewalls to electrically connect to the inductance element, the lower end extending from a lower portion of the first sidewall and being adapted to electrically connect to a circuit board;

a lid for covering the inductance element; and

a positioning device disposed between the lid and at lest one of the first sidewalls to position the lid onto the casing.

2. The package structure of claim 1, wherein the lid has two opposite first sides and two opposite second sides, the positioning device has a convex portion formed on at least one of the two first sides of the lid and a concave portion adapted to match with the convex portion, and the concave portion is formed on a top of the corresponding second sidewall.

3. The package structure of claim 2, wherein when the convex portion of the lid matches the concave portion of the second sidewalls, a distance is formed between one of the second sides of the lid and the conductive terminals.

4. The package structure of claim 1, wherein the upper portion of each of the conductive terminals extends from an upper surface of the first sidewall, and the lower portion of each of the conductive terminals extends from an lower surface of the first sidewall.

5. The package structure of claim 1, wherein the lid is a sheet-like structure.

6. The package structure of claim 1, wherein the circuit board is a printed circuit board.
