Abstract
The utility model discloses a kind of SMT Inductor for improving base, the SMT Inductor includes the coil windings on base, the I-shaped magnetic core for being located at submounts, magnetic core, one end of the magnetic core is pasted onto the submounts with PIN, weld the termination of the PIN of base and coil windings, the base without breach is provided with the black plastic of PIN end, base is provided with electric spark stricture of vagina with magnetic core adhesive surface.Due to adopting said structure, the product quality and production efficiency of the SMT Inductor are improve.
Description
Technical field
This utility model belongs to technical field of electronic components, more particularly to a kind of SMT Inductor for improving base.
Background technology
With developing rapidly for electronics and information industry, patch type electronic devices and components are adopted in a large number.SMT Inductor is exactly
One of them, SMT Inductor in the market includes base, and submounts are equipped with I-shaped magnetic core, wired above magnetic core
Circle winding, one end of magnetic core are pasted onto the termination weldering of the submounts with PIN, 4 PINs of base and coil windings
Connect.Find in use, this SMT Inductor has problems with：One is that PIN is not thorough in scolding tin aftershaping, produces during production
Product are stuck in material strip and cannot take out, and badly influence the quality of chip inductor；Two is the PIN indentation, there PIN top of base
Black injection molded layers are relatively thin, and during PIN molding, black injection peeling damages tear, although carries out debugging to PIN former and subtracts
Little molding dynamics, but produce little effect；Three is that magnetic core is not also differed with their thermal coefficient of expansion with the material of base, therefore exists
After receiving the transmission of welding heat, magnetic core is easily loosened with base, although increase adhesive glue amount in process of production, to increase glue
Body viscosity but produce little effect.
Content of the invention
The purpose of this utility model is to provide a kind of SMT Inductor for improving base.
The purpose of this utility model is achieved through the following technical solutions, and the SMT Inductor includes base, is located at
Coil windings on the I-shaped magnetic core of submounts, magnetic core, one end of the magnetic core are pasted onto on the base with PIN
Weld the termination of face, the PIN of base and coil windings.
Preferably, breach is provided with the base is without PIN end black plastic.
Preferably, increase PIN black parcel plastic layer thickness at PIN.
Preferably, electric spark stricture of vagina is provided with base and magnetic core adhesive surface.
Preferably, 5 PINs of base are welded with the termination of coil windings.
The beneficial effects of the utility model：Due to adopting said structure, base PIN opposite without PIN black
Breach is provided with injection, and the direction that puts on mould when making production can be exchanged with 180 random degree, carry production efficiency
Height, at the same can bilateral molding, be more thoroughly close to 90 degree than unilateral molding before non-gap, improve the product quality of inducer；
Increase PIN black parcel plastic layer thickness at PIN, make the PIN top black parcel injection in molding of inducer PIN
Cylinder block strength increases, it is to avoid peeling damages phenomenon；In base and magnetic core adhesive surface punching press electric spark stricture of vagina, to increase base and magnetic
The contact area of core abutting edge, increases the bonding strength of base and magnetic core, prevents because heat is received in welding and magnetic core is disengaged with base
Loosen, improve the product quality of SMT Inductor.
Description of the drawings
Of the present utility model embodiment is described in detail below in conjunction with the accompanying drawings
Fig. 1 is schematic diagram of the present utility model
Schematic diagrams of the Fig. 2 for this utility model base
Schematic diagrams of the Fig. 3 for prior art base
In figure：1st, 7, electric spark stricture of vagina at chassis base 2, magnetic core 3, coil windings 4, PIN 5, breach 6, thickening.
Specific embodiment
As shown in Figure 1, 2, the SMT Inductor includes base 1, the I-shaped magnetic core 2 being located above base 1, magnetic core 2
On coil windings 3, one end of magnetic core 2 is pasted onto above the base 1 with PIN, the PIN of base 1 and coil windings
Termination is welded, and increases breach 5 in base 1 without at the black injection of PIN end, increases PIN black parcel plastic cement at PIN
Thickness degree 6, in base 1 and 2 adhesive surface punching press electric spark stricture of vagina 7 of magnetic core, 5 PINs 4 of base are welded with the termination of coil windings 3
Connect.
