Technical field
The utility model relates to patch type electronic component technology field, is specifically related to a kind of chip inductor.
Background technology
Patch type electronic component is widely used in the information industry of develop rapidly, SMT Inductor is exactly one of them, inductor magnetic material used is in the market mostly Ferrite Material, simultaneously, two sections of the inductor of current paster are welded respectively enamelled wire termination, also because some faults of construction cause its volume larger, loss is large simultaneously; Miniaturization, high efficiency ability is inadequate; Meanwhile, the termination of the enamelled wire of existing SMT Inductor and paster adopt welding manner, and this welding portion and paster thereof form a projection, and this projection is unfavorable for the bonding of inductor itself, and impact is used.
Summary of the invention
Technical problem to be solved in the utility model is, for above-mentioned deficiency of the prior art, to provide a kind of SMT Inductor, and it adopts one end welding enamelled wire, and this welding ends does not have projection simultaneously, is conducive to the bonding use of inductor itself.
The utility model solves the technical scheme that its technical problem adopts: a kind of chip inductor, comprises " work " font coil rack, the winding section in the middle of coil rack comprises and the end of both sides; The upper surface of the end of coil rack both sides is respectively equipped with clamping groove, is provided with magnetic stripe mounting groove on middle winding section, and magnetic stripe is placed in magnetic stripe mounting groove; Coiling enamelled wire on described winding section;
Also comprise clamping shell, the clamping projection that clamping shell two ends are provided with on coil rack, clamping groove is corresponding, snapping in the clamping groove of clamping projection embedding coil rack;
The side opening of an end of described coil rack is provided with welding groove, this end is welding ends, in welding groove, be divided into two weld parts in left and right by baffler, in each weld part, be provided with paster, welding groove both sides are also provided with and the weld zone being connected that is conducted, enamelled wire end, and described weld zone is provided with the tin layer for strengthening connection reliability; Described enamelled wire comprises two terminations, and two terminations extend in welding groove via two lead-in wire breach of welding ends lower surface respectively.
One as above-mentioned tin layer structure is improved, and described tin layer is soldering-tin layer or some tin layer.
One as above-mentioned magnetic stripe and clamping shell is improved, and described magnetic stripe adopts amorphous alloy, and described clamping shell adopts single injection-molded.
A kind of chip inductor described in the utility model, it has the following advantages:
In the utility model chip inductor, magnetic stripe is assembled in magnetic stripe mounting groove, entirety adopts clamping shell parcel, overall structure is small and exquisite, easy to assembly, be positioned at the end face of an end of I-shaped wire ring framework due to the welding of enamelled wire simultaneously, make whole welding process reversed line ring framework back and forth, be convenient to assembling, be convenient to realize miniaturization; The utility model, in the Welding Structure of end face, has adopted groove to hold welding termination and the paster of enamelled wire, makes the platform after welding just fill and lead up whole groove, and whole welding ends does not have boss, is conducive to the bonding use of inductor.
