Description

Induction structure

Technical field

The utility model refers to a kind of induction structure especially about a kind of electronic building brick.

Background technology

Inductor (Inductor) is called coil (coil) again, a kind of for passive component, and its be have resist any electrorheological voltinism can electronic building brick, it is twining plug by coil is formed, and plug can be magnetic or nonmagnetic material; And inductor is to change by coil current, to produce magnetic flux change, and the electronic building brick of making according to the phenomenon in magnetic field, wherein, to be electric charge flowing in the source in magnetic field, and alternating current fails to be convened for lack of a quorum and produces magnetic field, and the magnetic field of change can induce electric current, the ratio of its linear relationship, we are called inductance.

Usually have only the plain conductor coiled, have self-induction action, with more than one lead coiling, the mutual inductance effect then arranged; The function of inductor is the noise in the filter current, electric current in the stabilizing circuit, to prevent Electromagnetic Interference, effect is similar with capacitor, be to store, to discharge the stability that the electric energy in the circuit is regulated electric current equally, only electric capacity is to come store electrical energy with the form of electric field (electric charge), and inductance is to reach with the form in magnetic field.

Can change mutually between electricity and the magnetic, can produce magnetic field around the lead that electric current flows through; Opposite, can produce electric current in the coil of cutting magnetic line.The structure of inductance is the coil that the lead coiled is close to each other, when electric current flows through, wherein can be full of magnetic energy, and the magnetic energy in the electrorheological hour, coil can produce one strength, stops electric current to change.

Traditional induction structure as shown in Figure 1, is made of housing 10a, coil 20a and plug 30a; This housing 10a is provided with accommodation chamber 11a, and offers two wire hole 12a that communicate with this accommodation chamber 11a in this housing 10a left and right sides; This coil 20a is located in this accommodation chamber 11a, and this coil 20a has the first terminal 21a, winds and folded mutually layer by layer two or more ring body 22a and the second terminal 23a that connects this ring body 22a from this first terminal 21a end, this first,

second terminal

21a, 23a forging and pressing are for flat, and pass and be positioned at the both sides of this housing 10a from these two wire hole 12a respectively; This plug 30a is arranged among this coil 20a, and is located in this accommodation chamber 11a; Whereby, constitute this induction structure, again this induction structure is welded on the circuit board 40a by this first,

second terminal

21a, 23a at last.

Yet, above-mentioned induction structure, on this body structure and actual the use, still have following shortcoming, because of this first, the second terminal 21a, the 23a forging and pressing are flat, so this is first years old, the

second terminal

21a, 23a sectional area everywhere is all inconsistent, also different with the sectional area of this ring body 22a, therefore comparatively unstable in the time of will causing electric current to flow through this coil 20a, in addition, be positioned at this housing 10a both sides and be welded on this circuit board 40a this first, the

second terminal

21a, 23a, will take this circuit board 40a and go up additional space, in addition, only with this first, the

second terminal

21a, 23a and this circuit board 40a welding, can cause this induction structure on fixing very built on the sand.
