Abstract
The utility model discloses a magnetic core with a multi-strand lead wire. The magnetic core comprises a magnetic core, wherein a lead pin is arranged on the bottom end of the magnetic core; and a lead wire formed by winding a plurality of strands of copper insulating enameled wires in parallel is arranged on the lead pin. The magnetic core provided by the utility model has the beneficial effects of good current limiting effect and low temperature rise.
Description
Technical field
The utility model relates to the electronic component technology application, particularly a kind of magnetic core that adopts the multiply lead-in wire.
Background technology
Traditional magnetic core lead-in wire winding mode is that sub-thread thick line footpath is wound around, yet this mode exists shortcoming.The problem existed is that the electronics handling capacity is poor, and temperature rise, easily cause the turn-to-turn paradoxical discharge, and then cause security incident.
Summary of the invention
The purpose of this utility model is in order to address the above problem, and has designed a kind of magnetic core that adopts the multiply lead-in wire.
Realize that the above-mentioned purpose the technical solution of the utility model is, a kind of magnetic core that adopts multiply lead-in wire, comprise magnetic core, and the bottom of magnetic core is provided with pin, and pin is provided with the copper enamel insulated wire of multiply and around the lead-in wire formed.
The quantity of described copper enamel insulated wire is the 4-8 thigh.
The number of described pin is at least one.
Utilize the magnetic core of the employing multiply lead-in wire of the technical solution of the utility model making, can meet the metering function in circuit, can guarantee that again temperature rise can be not too high, effectively avoid the turn-to-turn paradoxical discharge hidden danger of copper enamel insulated wire.
The accompanying drawing explanation
Fig. 1 is the structural representation of the magnetic core of employing multiply lead-in wire described in the utility model;
In figure, 1, magnetic core; 2, pin; 3, lead-in wire.
Embodiment
Below in conjunction with accompanying drawing, the utility model is specifically described, as Fig. 1 is the structural representation of the magnetic core of employing multiply lead-in wire described in the utility model, as shown in the figure, a kind of magnetic core that adopts the multiply lead-in wire, comprise magnetic core 1, the bottom of magnetic core is provided with pin 2, and pin is provided with the copper enamel insulated wire of multiply and around the lead-in wire 3 formed.Wherein, the quantity of described copper enamel insulated wire is the 4-8 thigh; The number of described pin is at least one.
The characteristics of the technical program are: the lead-in wire that connects pin adopts multiply and around mode (this programme adopt 6 strands and around), the characteristics of having utilized electronics easily to transmit at conductive surface, it is kelvin effect, simple saying is exactly to have increased the surface area of wire with respect to traditional scheme, such technology mode can meet the metering function in our circuit, can guarantee that again temperature rise is unlikely too high, effectively avoid the turn-to-turn paradoxical discharge hidden danger of copper enamel insulated wire.。
Technique scheme has only embodied the optimal technical scheme of technical solutions of the utility model; those skilled in the art have all embodied principle of the present utility model to some changes that wherein some part may be made, within belonging to protection range of the present utility model.
