Description
Technical field
It the utility model is related to circuit components technical field, more particularly to a kind of resistance with inductance coil.
Background technology
Current-limiting resistance is often series in circuit, to limit the size of place branch current, is burnt out to prevent electric current is excessive
The component connected.Current-limiting resistance can also play partial pressure simultaneously.
Inductor is the element that electric energy can be converted into magnetic energy and stored.The structure of inductor is similar to transformation
Device, but an only winding.Inductor has certain inductance, and it only hinders the change of electric current.If inductor is in no electricity
In the state of stream passes through, it will attempt to hinder electric current to flow through it when circuit is connected；If inductor is in the state for having electric current to pass through
Under, it will attempt to maintain electric current constant when circuit disconnects.
In same circuit, resistance and inductance usually can be used simultaneously, when in use, generally by both elements point
Do not use, it is big that this method has an area occupied, installs the shortcomings that complicated.There is a kind of integrated component on the market at present, can
Possess the function of resistance and inductance simultaneously, and the resistance in this integrated component is also easy to produce substantial amounts of heat in use, such as
Fruit can not radiate in time, dangerous, generation security incident easily easily occur.
Utility model content
The purpose of this utility model is to solve shortcoming present in prior art, and the one kind proposed carries inductor wire
The resistance of circle.
To achieve these goals, the utility model employs following technical scheme：
A kind of resistance with inductance coil, it is characterised in that：Including resistance, resistance both ends are equipped with resistance lead,
Socket inductance coil, inductance leads are respectively equipped with inductance coil both ends on the outside of resistance.
Preferably, the resistance is current-limiting resistance, and the insulation shell of cylinder is provided with the outside of resistance.
Preferably, the inductance coil includes wire, and wire is in the shape of a spiral around being connected on the outside of resistance.
Preferably, the wire is cylindrical, copper wire, is provided with one group of radiating rack on the outside of wire, each radiate rack
Set along the axis direction of wire, radiating rack uniform intervals are distributed on the circumference of wire half, in wire with dissipating
Insulating barrier is equipped with the outside of hot rack.
The utility model has the advantage of：A kind of resistance small volume with inductance coil provided by the utility model,
It can be socketed in simultaneous with the function of resistance and inductance, inductance coil on the outside of resistance, inductance coil contributes to resistive dissipation, drop
Low-resistance temperature.

Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only explaining
The utility model, it is not used to limit the utility model.
As shown in Figure 1, Figure 2 and Figure 3, a kind of resistance with inductance coil provided by the utility model, it is characterised in that：
Including resistance 1, resistance 1 is current-limiting resistance, is provided with the insulation shell of cylinder in the outside of resistance 1, electricity is equipped with the both ends of resistance 1
Hinder lead 2.In the outside of resistance 1 socket inductance coil 3, inductance coil 3 includes wire 5, and wire 5 is cylindrical, copper wire, is led
The outside of line 5 is provided with one group of radiating rack 5.1, and each rack 5.1 that radiates is set along the axis direction of wire 5, and radiate rack 5.1
Uniform intervals are distributed on the circumference of the half of wire 5, and insulating barrier, wire are equipped with wire 5 and the outside of radiating rack 5.1
5 in the shape of a spiral a circle suffer a circle and set around the outside of resistance 1, radiating rack 5.1 is connected on towards outside, wire 5 and radiating rack 5.1 1
Aspect can form inductance coil, and the caused heat that on the other hand resistance 1 can be worked disperses, at the both ends of inductance coil 3
It is respectively equipped with inductance leads 4.
