Surface mount inductor

Abstract

A surface mount inductor includes a core having two erected side panels each having a conductor contact attached to a lower portion, and a central part coupled between the side panels for forming an H-shaped core, a wire wound around the central part of the core and having two terminals coupled to the conductor contacts of the core, and a casing having a chamber formed between a front plate and a rear plate and an upper plate for receiving the core and for forming an improved structure having a decreased height, and the central part of the core is opened for allowing the wire to be easily and quickly wound onto the central part of the core.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to the drawings, a surface mount inductor 1 in accordance with the present invention comprises a substantially H-shaped core 10 made of ferrite materials, ceramic materials or the like, and formed by such as molding or mold-injection processes, and including two vertical or erected side panels 11, 12 each having a conductor contact or welding material or member 13, 14 attached or secured to the lower or bottom portion 15 thereof for electrically coupling or securing to various electric circuit boards (not shown) or the like, and including a horizontal or central part 16 horizontally coupled between the side panels 11, 12 for forming the H-shaped core 10.

A wire 20 is wound around the horizontal part 16 of the core 10 and includes two ends or terminals 21, 22 coupled to the conductor contacts or welding materials or members 13, 14 of the core 10 respectively for electrically coupling to the electric circuit boards via the conductor contacts or welding materials or members 13, 14 of the core 10. A casing 30 includes a chamber 31 formed therein and defined between a front plate 32 and a rear plate 33 and an upper plate 34 for receiving the core 10 and for forming the surface mount inductor 1. The casing 30 may also be made of ferrite materials, ceramic materials or the like, and may also be formed by such as molding or mold-injection processes or the like.

It is preferable that the front plate 32 and the rear plate 33 of the casing 30 are disposed or arranged or positioned on the front and the rear portions of the core 10, and/or the side panels 11, 12 and the horizontal part 16 of the core 10 are disposed or arranged or positioned between the front plate 32 and the rear plate 33 of the casing 30, and/or the side panels 11, 12 of the core 10 are disposed or arranged or positioned on the two open side portions 35 of the casing 30 and preferably engaged with the front plate 32 and the rear plate 33 of the casing 30 for enclosing the chamber 31 and/or the two open side portions 35 of the casing 30, and thus for suitably receiving the coiled wire 20 within the chamber 31 that is now defined between the front plate 32 and the rear plate 33 of the casing 30 and the side panels 11, 12 of the core 10.

It is to be noted that the upper plate 34 of the casing 30 and the horizontal part 16 of the core 10 may include a suitable height or thickness such that the height of the present surface mount inductor may be made to the required or decreased height. Furthermore, the horizontal part 16 of the core 10 is opened such that the wire 20 may be easily and quickly engaged or wound onto and around the horizontal part 16 of the core 10 with various automatic machines or facilities (not shown).

Accordingly, the surface mount inductor in accordance with the present invention includes an improved structure having a suitable or decreased height, and for allowing the surface mount inductor to be easily and quickly manufactured.

Although this invention has been described with a certain degree of particularity, it is to be understood that the present disclosure has been made by way of example only and that numerous changes in the detailed construction and the combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as hereinafter claimed.
