Description
Technical field
The utility model relates to inductive technologies field, is specifically a kind ofly applied in modern electronic technology field the SMD low-frequency antenna of slim three-dimensional needing low frequency wake-up Signal transmissions.
Background technology
Antenna is as the critical component of mobile communication product, and its radiation efficiency, size, directivity, bandwidth, impedance matching property and manufacturing cost etc. have great impact to mobile communication product.And the practical development in current mobile communications market also to the miniaturization of communication products, light and handy, attractive in appearancely propose more and more higher requirement.But currently marketed low-frequency antenna is said from each side such as volume, receiving sensitivity, anti-dust performance, anti-soil shock resistance, anti-drop abilities and can not be met the need of market all far away.
Utility model content
Not enough for prior art, the utility model provides the SMD low-frequency antenna of the slim three-dimensional of small size of dust-proof, anti-soil antidetonation, the anti-drop ability of a kind of high receiving sensitivity, wide in range temperature range and Geng Gao.
The technical scheme in the invention for solving the above technical problem is: the SMD low-frequency antenna of a kind of slim three-dimensional, comprise split type bobbin and FERRITE CORE, it is characterized in that, described split type bobbin is the three-dimensional bobbin of "] [" shape with winding slot; FERRITE CORE is fixed in the middle part of split type bobbin and forms X-axis winding slot and Y-axis winding slot, and described split type bobbin side winding slot is Z axis winding slot; Described split type bobbin is provided with multiple pad; Described X, Y, Z axis winding slot is coiling X, Y, Z axis coil respectively, and this X, Y, Z axis coil is relative to described FERRITE CORE center orthogonal vertical and be connected with described pad respectively and draw, for connecting external equipment.
Further, described split type bobbin four edge bottom surfaces are symmetrical arranged small one and large one two pads respectively; Described "] [" shape split type bobbin Side symmetrical arranges multiple pad.
Further, described pad is alloy material and with coating.
Further, described split type bobbin top arranges baffle plate, and described baffle plate surrounds Z axis winding slot and the location notch for fixing FERRITE CORE.
Further, described FERRITE CORE is square core.
Further, described split type bobbin is highstrenghtpiston's skeleton.
The utility model can be satisfied with the reception of low frequency field signal as the reception of PEPS aerial signal, has high reception stability, high receiving sensitivity, thinner advantage less of conventional receiver antenna; Have the dust-proof of wide in range serviceability temperature scope and Geng Gao, anti-soil antidetonation, anti-drop ability, can meet the requirement of different environment for use simultaneously; This kind of skeleton structure can realize the miniaturized of volume and the impact that can effectively reduce product, is new technological innovation to three-dimensional reception antenna field.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As Figure 1-4, the SMD low-frequency antenna of a kind of slim three-dimensional, comprise split type bobbin 1 and FERRITE CORE 2, it is characterized in that, described split type bobbin 1 is the three-dimensional bobbin of "] [" shape with winding slot, the FERRITE CORE 2 sticky note of electronics binding agent (glue) is fixed in the middle part of split type bobbin 1, and part skeleton and the set of part magnetic core form X-axis winding slot 5 and Y-axis winding slot 6, and described split type bobbin side winding slot is Z axis winding slot 7; Described split type bobbin 1 is provided with multiple pad 3; Described X, Y, Z axis winding slot is coiling X-axis coil 51, Y-axis coil 61 and z axis circle 71 respectively, this X, Y, Z axis coil is relative to described FERRITE CORE 2 center orthogonal vertical and be connected with described pad 3 respectively and draw, by connecting external equipment by paster mode.
Further, as shown in figures 1 and 3, pad 3 is imbedded wherein with fundamental symmetric mode by the split type bobbin 1 of described plastic material in injection moulding process simultaneously, pad 3 split type bobbin 1 bottom surface and side distribution for be connected institute around coil also and client's side link, wherein, described split type bobbin 1 four edge bottom surfaces are symmetrical arranged the pad 3 of small one and large one two flat horizontal surface shapes respectively, described "] [" shape split type bobbin 1 side is symmetrical arranged multiple convex shaped pad 3, described pad 3 is alloy material and with coating, in case oxidation, described convex shaped pad design both ensure that the possibility that the many caves of baffle plate 4 plastics are shaping, made again the position distribution of side bonding pads reasonable, facilitated the following process scolding tin of product.
Further, as shown in Figure 3, described split type bobbin top arranges baffle plate 4, surrounds Z axis winding slot 7 and the location notch for fixing FERRITE CORE bottom described baffle plate 4 and split type bobbin 1.
Further, described FERRITE CORE 2 is square core, and described split type bobbin 1 is highstrenghtpiston's skeleton.
The utility model can also adopt Embedding Material to carry out embedding or encapsulation to overall structure in disposable tool.Described Embedding Material is RF application proprietary material, is used for sealing integral product, has good thermal diffusivity, water proofing property and anti-high and low-temp impact property.The SMD low-frequency antenna product of a kind of slim three-dimensional described in the utility model patent is divided in structural entity can be with shell and can not be with shell two kinds of modes, can select as required.
Operation principle of the present utility model is the use of the winding slot of magnetic core (block) as inductance of the plastic skeleton replacement fragility of high strength, improve the intensity of whole reception antenna, the square core of simple structure has been selected to reduce the cost of product and structure is more reliable, decrease the risk that superfine enamelled wire is cut off by special-shaped magnetic core, improve the safe class of product, reduce the fraction defective of product, present or rhythm of production in the future preferably, what make antenna can be applied to occasion widely.
