Description

Three-dimensional radio frequency inductive

Technical field

Utility model relates to a kind of three-dimensional radio frequency inductive, belongs to the inductance machining technology.

Background technology

In the manufacturing field of existing three-dimensional inductance,, in processing procedure, divide three kinds of directions to do the action of winding coil in a conventional manner because of it contains the coil that three components are in X, Y, Z relative direction; Though adopt this mode can reach its effect and purpose, during because of Z group coil winding, cause through regular meeting and X, Y-axis coil kinking bad, to such an extent as to need pull down all coils coiling again, the increase production cost; And during coiling Z group coil, different during because of angle and the coiling X of its clamping base seat, Y-axis coil, must change chuck and can carry out, and because of coiling face is quite thin, direct coiling mortality is quite high, to sum up will significantly increase production cost.

In addition, in existing three-dimensional radio frequency inductive, its terminal of exerting oneself is often too short and be hidden in the bottom, causes the rear end user on this induction soldering behind the machine plate, can only be with the touching of hand sense organ to determine its tightness, and this will increase user's inconvenience and cost.

And the coil copper cash of general three-dimensional inductance is comparatively tiny, thus be wound in and get loose easily when exerting oneself terminal in the take-up that rises X-axis coil and Y-axis coil, and when z axis snare upper core, having pushed take-up causes damage easily.

The utility model content

Technical problem:

Technical problem to be solved in the utility model is to provide a kind of three-dimensional radio frequency inductive and manufacture method thereof at worker method complexity and the high defective of coiling z axis circle mortality that prior art exists.The manufacture method of three-dimensional radio frequency inductive described in the utility model aborning, worker's method change of z axis circle is made the effect that the consume cost reduces, processing procedure is simplified to reach; Effectively protect the playing unlikely being damaged of take-up of X-axis coil and Y-axis coil and reduce fraction defective at four wire casings of foundation design; On the terminal of exerting oneself, its length growth makes progress smooth in the side of base seat, makes things convenient for the rear end user to check the welding tightness in visual mode, can increase the ease of use of product by this in addition.

Technical scheme:

The three-dimensional radio frequency inductive of the utility model; it is characterized in that comprising pedestal; iron core; the X-axis coil; the Y-axis coil; from stickiness z axis circle and high tempreture tape; wherein pedestal and iron core all are flat square; four angles of pedestal all are provided with projection; all be provided with two terminals of exerting oneself on each projection; totally eight terminals of exerting oneself; the horizontal winding X-axis coil of iron core; vertical winding Y-axis coil of iron core; from stickiness z axis circle be go ahead of the rest be placed in behind the coil of independent winding moulding iron core around; iron core is fixed on the pedestal by epoxy resin; the X-axis coil; the Y-axis coil and from the terminal of stickiness coil respectively with the terminal welding of exerting oneself, again high tempreture tape is sticked on the overall inductance to protect the X-axis coil now; the Y-axis coil; from stickiness z axis circle.

Beneficial effect:

The utility model causes bad to preceding two groups of coil kinkings when effectively reducing because of coiling, three groups of coils are coilings expensive again all; This worker method also can be simplified cost because of the processing procedure simplification in addition; So the utility model all improves widely for the height that causes because of processing procedure is loaded down with trivial details consume, expensive situation and rear end user's that the three-dimension type inductance is faced when producing convenience; Make quality and cost be easy to control, the tightness test that use the rear end is more convenient, is the quantum jump of three-dimensional radio frequency inductive on making.

Embodiment

Be elaborated below in conjunction with the technical scheme of accompanying drawing to utility model:

As shown in Figure 1, the three-dimensional radio frequency inductive that the utility model is made, its material comprises at least: a base seat 10 comprises eight 111,112,121,122,131,132,141,142 and four

wire casings

15,16,17,18 of terminal of exerting oneself, one flat square iron core 20, three groups of

coils

30,40,50 and high tempreture tape 60.

Desiring to make this three-dimensional radio frequency inductive may further comprise the steps at least:

(1) make a flat iron core 20 with magnetic ferrites for the moulding material, this iron core is a class four directions type pattern, precisely because four angles have circular shape;

(2) this iron core 20 is attached on the base seat 10 with epoxy resin, this base seat is high liquid crystal molecule material, and eight terminals 111,112,121,122,131,132,141,142 of exerting oneself are arranged;
