Description
Technical field
The utility model relates to electronic component technology field, refers to a kind of inductor especially.
Background technology
Inductor is a kind of can be the device that magnetic energy stores electric energy conversion.It is widely used in the design of various electronic circuit as main electronic component, is to realize the indispensable electronic component of majority circuit function.
The iron core that the inductor that present stage uses generally all is made up of I sheet and E sheet and wire coil form, coil does not have shell coated, easily cause inductance ratio not high because of leakage field, and exposed coil is easily subject to the destruction of water and corrosive gas, reduces the useful life of inductor.
Utility model content
The utility model is not enough for above-mentioned prior art, provides a kind of inductor that can reduce leakage field, improve water proof and dust proof effect.
The utility model solves the technical scheme that its technical problem adopts: a kind of inductor, comprise I sheet, E sheet, glue core and coil, coil is provided with lead-out wire, described glue core is the cube structure of hollow, the upper and lower surfaces correspondence of glue core offers E sheet installing port, and the side opening of glue core is provided with coil installing port, is provided with the fairlead installing lead-out wire bottom glue core, also comprise the lower casing holding E sheet and the upper casing holding I sheet, described upper casing and lower casing are fastenedly connected.
Described a kind of inductor, its lower casing top is provided with snap fit, and described upper casing is provided with the hole clipping with snap fit adaptation.
Described a kind of inductor, is provided with insulating barrier between its coil and glue core.
The beneficial effects of the utility model are: the coil on E sheet is completely glue in-core, increase the coated area of wire coil, effectively can reduce leakage field, improve inductance ratio, and E sheet and I sheet and glue core are packaged together by lower casing and upper casing, can effective anti-sealing, rain, the erosion of snow and corrosive gas, dust is to the destruction of parts, add the useful life of inductor, lower casing is connected with upper casing buckle, makes the structure of product become simple, and assembles and convenience.
Accompanying drawing explanation
Fig. 1 is three-dimensional exploded view of the present utility model;
Fig. 2 is the overall structure figure that the utility model overlooks direction;
Fig. 3 is the overall structure figure that the utility model looks up direction.
Each Reference numeral is: 1-lower casing, 2-I sheet, 3-glue core, 4-E sheet, 5-upper casing, 6-lead-out wire, 7-snap fit, 8-hole clipping.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
With reference to Fig. 1, shown in Fig. 2 and Fig. 3, the utility model discloses a kind of inductor, comprise I sheet 2, E sheet 4, glue core 3 and coil, coil is provided with lead-out wire 6, described glue core 3 is the cube structure of hollow, the upper and lower surfaces correspondence of glue core 3 offers E sheet installing port, the side opening of glue core 3 is provided with coil installing port, coil can be put into glue core 3 from coil installing port during use, then the center pillar of E sheet 4 is inserted from E sheet installing port, coil is just sleeved on the center pillar of E sheet 4 thus, insulating barrier is provided with between coil and glue core 3, the fairlead installing lead-out wire 6 is provided with bottom glue core 3, also comprise the lower casing 1 holding E sheet 4 and the upper casing 5 holding I sheet 2, when E sheet 4 and I sheet 2 install, E sheet 4 and I sheet 2 are packaged together with glue core 3 by lower casing 1 and upper casing 5, and glue core 3 by coil encapsulation on E sheet 4, described upper casing 5 and lower casing 1 are fastenedly connected, as a kind of specific embodiment, lower casing 1 top is provided with snap fit 7, described upper casing 5 is provided with the hole clipping 8 with snap fit 7 adaptation, be connected with the buckle of upper casing 5 to realize lower casing 1.Certainly, shell 1 and upper casing 5 also realize being tightly connected by bonding or other mode.
Compared with existing electronic inductor, coil on the utility model E sheet 4 is completely in glue core 3, increase the coated area of wire coil, effectively can reduce leakage field, improve inductance ratio, and E sheet 4 and I sheet 2 are packaged together with glue core 3 by lower casing 1 and upper casing 5, can effective anti-sealing, rain, the erosion of snow and corrosive gas, dust is to the destruction of parts, add the useful life of inductor, lower casing 1 is connected with upper casing 5 buckle, make the structure of product become simple, and assemble and convenience.
Above-described embodiment is illustrative principle of the present utility model and effect thereof only; and the embodiment that part is used; for the person of ordinary skill of the art; without departing from the concept of the premise of the invention; can also make some distortion and improvement, these all belong to protection range of the present utility model.
