Description
Technical field
Inductance coil technical field is the utility model is related to, more particularly to a kind of high-frequency wireless communication transmission channel device
F type inductance coils.
Background technology
It is well known that inductance coil is to be enclosed to enclose the land by one by wire one to be wound on insulation tube, wire insulate each other, and
Insulation tube can be hollow, can also include iron core or powder core, abbreviation inductance.The nickname of inductance coil inductor, utilize
The device that the principle of electromagnetic induction is operated.Inductance coil is the device being operated using the principle of electromagnetic induction.When having
When electric current flows through a wire, certain electromagnetic field will be produced around this root wire, and the wire sheet of this electromagnetic field
To being in the wire in the range of this electromagnetic field induction effect can occur for body again.The work that the wire for producing electromagnetic field occurs in itself
With being called self-induction, i.e., variable-current caused by wire oneself produces variation magnetic field, and this magnetic field further have impact in wire
Electric current；To being in effect caused by other wires of this electromagnetic field scope, it is called mutual inductance.The electrical characteristics and electricity of inductance coil
Container leads to low frequency on the contrary, resistance high frequency.High-frequency signal can run into very big resistance when passing through inductance coil, it is difficult to pass through；And to low
Frequency signal passes through that the resistance presented when it is then smaller, i.e., low frequency signal can easier pass through it.Inductance coil is to straight
The resistance for flowing electricity is almost nil.Resistance, electric capacity and inductance, certain resistance can be presented for the flowing for electric signal in circuit in they
Power, this resistance we term it the impedance that " impedance " inductance coil is presented to current signal utilize be coil self-induction.
Sometimes it is referred to as " inductance " or " coil " to inductance coil by we, is represented with alphabetical " L ".During coiling inductance coil, institute's coiling
The number of turns of circle we be typically referred to as the number of turn inductance coil of coil performance indications be exactly mainly inductance value size.Separately
Outside, in general the wire of coiling inductance coil always has certain resistance, and this usual resistance is very little, can be ignored not
Note.But when the electric current flowed through in some circuits is very big, the resistance of this very little of coil cannot have ignored, because very big
Electric current can consume power on this coil, cause coil heating or even burning out, so sometimes it is also contemplated that coil energy
The electrical power born.
In recent years, with the fast development of society and the extensive use of precise electronic component, led in high-frequency communication technology
Domain, wireless communication technology have been widely used, such as the most frequently used intercom equipment, and at present, traditional building talkback leads to
Equipment is believed mainly using high-frequency signal, but with the continuous increase of building density, the continuous complication of floor structure, this
A little wall blocking structures cause intercommunication signal constantly to weaken, and therefore, in order to ensure communication quality, people's generally use is increase
The power of talk back equipment, but as the increase of power, the volume increase of communication equipment, energy consumption increase, meanwhile, in communication equipment
Interference between the multiple parts in portion also constantly increases, and in order to reduce the electromagnetic interference between electronic equipment, people design
Shielding box, but because the size of shielding box is smaller, inner space is limited, if traditional inductance coil is reduced into volume applications
In that in shielding box, then can produce new technical problem, i.e., the electromagnetic balance in shielding box is broken, so being directed to existing skill
The drawbacks described above of art, the F type inductance coils for designing and developing a kind of high-frequency wireless communication transmission channel device seem it is particularly heavy
Will.
